However, the existing tripod has two outstanding problems that 1, the tripod is erected on soft ground surface such as soil, or on the ground surface with larger roughness and obvious hollowness, so that the tripod can be better fixed and prevented from slipping and falling. 2. Because the tripod legs are extremely sharp and need to penetrate below the ground to provide stability, the ground needs to be damaged, and especially for vulnerable or damaged ground materials, such damage is often irreversible.
The problem of damage caused by the stable manner of the tripod is particularly serious in the field of ancient architecture. For example, when the earth surface is measured in a smoother ancient architecture room, the tips of the tripod can only be inserted into the joints of the brick joints as much as possible so as to prevent lateral sliding, and on some weaker earth surface materials, the sharp tips can damage the earth surface materials. In addition, in the measuring process in the pit in the archaeological field, as the underground pit is in the muddy earth surface, the support feet of the tripod can be pricked into the ground, thereby damaging archaeological remains and causing certain measuring trouble. For the above reasons, it is highly important to develop a nondestructive tripod fixing method to ensure that the tripod cannot slip due to the influence of the ground surface material, especially for tile-type ground surfaces, and to ensure that the ground surface material cannot be damaged.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
A harmless fixed chassis device for tripod tiptoe, as shown in figure 1, including the anti-skidding base 6 that links to each other with the tripod tiptoe, through anti-skidding base 6 and ground contact, avoided the tiptoe of traditional tripod to cause the harmful effects to the ground. The bottom of the anti-skid base 6 is provided with an anti-skid pad or a plurality of anti-skid protrusions 62, the lower end surfaces of the anti-skid protrusions 62 are spherical, and the spherical anti-skid protrusions are configured to be in multi-point contact, so that the anti-skid effect can be achieved, the pressure can be evenly spread, and the damage to the base is avoided. Meanwhile, the plurality of anti-slip bulges are equivalent to a plurality of non-sharp positioning points, so that sideslip or toppling can be avoided as long as one positioning point plays a lateral stop role, and meanwhile, the positioning is performed without being specially close to a brick joint on the ground.
The anti-skid base 6 is connected with the tripod toe through an angle adjusting mechanism, and the anti-skid base 6 can be fixed towards a specific angle in a certain range through rotation and positioning of the angle adjusting mechanism, so that the anti-skid base is suitable for supporting functions of different terrains.
The angle adjusting mechanism comprises a sleeve 1 connected with the tripod toe, and a friction ring 13 matched with the tripod toe is arranged inside the sleeve 1 to ensure the stability when the angle adjusting mechanism is inserted into the tripod toe. The friction ring 13 has smooth upper surface and rough lower surface, which is equivalent to barb structure, and is convenient for plugging and can not be easily loosened.
Two lug plates 11 are arranged at intervals at the bottom end of the sleeve 1, a fixed shaft 12 is connected between the two lug plates 11, and the fixed shaft 12 is fixedly arranged on the lug plates 11, namely, the fixed shaft 12 is fixedly connected with the sleeve 1. The fixed shaft 12 is fixedly provided with a ratchet wheel 4 and is rotatably connected with a special-shaped movable disc 5, and the anti-skid base 6 is rotatably connected with the fixed shaft 12 through a connecting rod 63. The special-shaped movable disc 5 and the anti-skid base 6 can rotate around the fixed shaft 12, namely, can rotate relative to the sleeve 1, and the ratchet wheel 4 is fixed relative to the sleeve 1.
Further, two connecting rods 63 are provided, and two connecting rods 63 are symmetrically arranged on two sides of the anti-skid base 6.
The anti-slip base 6 is provided with a pawl 61 matched with the ratchet, namely, when the anti-slip base 6 rotates around the fixed shaft 12, the pawl 61 can be matched with the ratchet in a clamping way, and then the anti-slip base 6 is positioned in an angle. In order to facilitate the pawl 61 to reciprocally adjust the positioning angle, the outer contour of the special-shaped movable disc 5, which is close to the ratchet teeth of the ratchet wheel 4, exceeds the outer contour of the ratchet teeth, i.e. when the pawl 61 rotates along with the anti-slip base 6 under the action of the special-shaped movable disc 5, the pawl will rotate closely to the outer contour of the special-shaped movable disc 5. But if the pawl 61 always rotates against the outer contour of the profiled movable disc 5, it will not always engage with the ratchet.
In order to make the pawl 61 timely cling to the outer contour of the special-shaped movable disc 5 to rotate and timely match with the ratchet in a clamping way, a limiting structure for limiting the rotation range of the special-shaped movable disc 5 is arranged on the ratchet wheel 4. The limiting structure comprises a stop protrusion 41 arranged on the ratchet wheel 4, and an arc limiting groove 51 matched with the stop protrusion 41 is arranged on the special-shaped movable disc 5. The pawl 61 can rotate conveniently without blocking only when rotating in the coverage range of the special-shaped movable disc 5, and when the pawl 61 exceeds the coverage range of the special-shaped movable disc 5, the pawl 61 can be matched with the ratchet in a clamping way, so that positioning is realized.
The use process of the invention is as follows:
First, as shown in fig. 1, when the anti-skid base 6 is not unfolded, the left end of the arc-shaped limiting groove 51 is in stop fit with the stop protrusion 41, the special-shaped movable disc 5 is located at the right limit position, at this time, the pawl 61 is in close fit with the special-shaped movable disc 5, and the angles of the pawl and the special-shaped movable disc are not changed relatively.
And secondly, as shown in fig. 2, the anti-skid base 6 is adjusted clockwise, and the pawl 61 drives the special-shaped movable disc 5 to rotate clockwise while following until the right end of the arc-shaped limiting groove 51 is in stop fit with the stop protrusion 41, and the special-shaped movable disc 5 is positioned at the left limit position.
And thirdly, as shown in fig. 3, the anti-skid base 6 is continuously adjusted clockwise, at the moment, the pawl 61 rotates clockwise relative to the special-shaped movable disc 5 while following, and contacts with the ratchet at the leftmost end of the ratchet wheel to realize clamping and fixing.
Fourth, as shown in fig. 4, if the inclination angle of the anti-skid base 6 needs to be adjusted to be small, the anti-skid base 6 is adjusted counterclockwise. At this time, the pawl 61 is engaged with the ratchet, and the outer contour of the special-shaped movable disc 5 near the ratchet of the ratchet wheel 4 exceeds the outer contour of the ratchet, and the pawl 61 drives the special-shaped movable disc 5 to rotate anticlockwise while following until the anti-slip base 6 is adjusted to a proper angle.
And fifthly, when the inclination angle of the anti-skid base 6 needs to be increased again, the anti-skid base 6 is continuously adjusted anticlockwise, the pawl 61 drives the special-shaped movable disc 5 to anticlockwise rotate while being driven, and the special-shaped movable disc 5 is located at the right limit position until the left end of the arc-shaped limiting groove 51 is in stop fit with the stop protrusion 41. At this time, the pawl 61 moves out of the contour of the profiled movable disc 5 from the engagement of the ratchet teeth while following, and then is adjusted according to the steps one to three.
The present invention is not limited to the conventional technical means known to those skilled in the art.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
