Description

One-touch clamping device for practical training materials with no abrasion and good settlement}

The present invention relates to a clamping device for training equipment, and more particularly, a clamping device used to fix and remove training equipment at a desired position on a training table in the form of a profile plate having slots provided at regular intervals. It is about.

In the field of technical engineering, experiments for academic research and technology development, as well as practical training for students, are used for various experimental and practical equipment. In particular, in the fields of aerodynamics, fluid roles, and electronics, they often refer to actual structures such as actuators, valves, gauges, and control boxes to connect and operate under realistic conditions through experiments or hands-on practice.

In the fixed placement of the equipment on the training board to experiment or practice using such equipment, the raw fixing method of fastening using bolts or the like takes a lot of time and it is difficult to change the layout, so the training efficiency is low. Therefore, for efficient experiment practice, it is necessary to quickly fix, separate, and relocate the equipment, and to fix the equipment so that the equipment is not moved or flowed by the pneumatic or hydraulic equipment or by frequent practice and experimentation. Many studies have been conducted for such a function and many patents have been filed.

For example, Korean Patent No. 10-0270567 proposes a clamping device that can be easily attached and detached training equipment such as various pneumatic or hydraulic equipment on the profile type training board formed with a predetermined interval. In this technique, when the clamp member is pulled by manipulating the lever member, the clamp member is in a position to be inserted into or detached from the slot of the training plate while the spring is forcibly contracted and the clamp member is inserted into the slot of the training plate. When the lever member is released, the clamp member can be fixed by pressing the one side edge of the opening of the slot by the elasticity of the spring which has been contracted. However, since the clamping device is clamped only in one direction in which the spring force acts on the slot of the training plate, the clamping device slides in the slot direction perpendicular to the direction in which the spring force acts due to vibration by air pressure or hydraulic pressure during training. The problem of losing flow has been found.

In order to solve this problem, the Republic of Korea Patent No. 10-0459291 is rotated approximately 90 degrees to the position that can enter and exit the slot opening of the training plate according to the rotational position and the posture that is fixed to the inside fixed to the opening It is equipped with a typical clamping element, a gear train in which one gear member with the clamping element and the other gear member with a handle are engaged so that the attitude of the clamping element is changed according to the handle operation so that it can be fixed or released with respect to the slot opening so that the training equipment is leveled. However, a technique that can be fixed in the inclined direction of a vertical or arbitrary angle is proposed. However, in this technique, since the clamping element is provided with only one clamping element formed at the center, the clamping element is weak and the curved protrusion is used as the clamping element. As the compression occurs, abrasion occurs and the fixed binding force is weakened.

On the other hand, the Republic of Korea Patent No. 10-0664976 has two racks (rack) instead of the other gear member of the clamping device is configured as a button type to be operated by pressing alternately side by side on both sides of the one gear member with the clamp element is clamped A clamping device is disclosed in which an element is brought into a locked state by one rack and a locked state is released by the other rack. In addition, the Republic of Korea Patent Publication No. 10-2004-0107212 to support the rotary device and the rotary device consisting of a movable piece having a pusher at one end and one or more rotating members rotated by the operation of the movable piece The pusher of the movable piece protrudes to one side, and the support and the outer flat surface of which the cover is assembled to the upper side are formed in a quadrangle, protrude downward from the bottom of the support, and are assembled with the rotating member so as to rotate according to the rotation of the rotating member. A clamp device including a cam is proposed. However, such a button or push-type clamp element has been found to be a problem that is easy to break, and also wear problems caused by frequent use, loosening the fastening force as the problem was found.

In addition, the Republic of Korea Patent No. 10-0746748 has a detachable portion including a removable member including a housing provided on the upper surface, a guide rail and a movable member provided on the housing, and a locking projection exposed to the lower portion of the housing. As a structure comprising a mechanism, a clamping device is proposed in which the detachable part is mounted in a slot in a one-touch concept by a locking means of a sliding movement method. However, this technology uses a press-fit method in which the locking method is pushed into the slot forcibly, so that the curved portion of the locking protrusion is worn down and loosened by frequent use, which weakens the fixed binding force, and is particularly vertical because only one locking protrusion is used. However, there is a problem that the stability may be lowered when supported at an inclined angle.

In addition, Korean Patent Laid-Open Publication No. 10-2010-0137703 discloses a lever member and a cam interlocking means in order to improve the problems of the conventional gear train method, that is, a problem of clamping failure and difficulty in machining due to wear and backlash of the gear mountain. The clamping device provided is proposed. However, since this technique only plays a role of holding by the elasticity of the shock absorber, there may be a problem of weak force and inferior stability when the shock absorber detaches.

In addition, the Republic of Korea Patent No. 10-1036889 has a clamping element having a latching jaw that is pressed by the clamp wedge and is fixed to the inside of one side edge of the slot opening to press the upper case to hold the upper case in the fixed and fixed state It proposes a clamping device which is separated by lifting and fixed and separated by one-touch operation. This technique is characterized in that the clamping element is prolonged in the conventional clamping device by improving the durability of the clamping element to be easily worn and loosened so that the clamping element is fastened to the slot by a pressure method rather than friction. However, this technique is advantageous in the horizontal profile, but it is difficult to use in the vertical profile or the inclined profile because it can be separated simply by lifting the upper case.

The present invention has been developed to solve the problems of the prior art as described above, the insertion and fixing to the profile slot is made smoothly by only one-touch operation, there is no wear of the clamping element is not loose in frequent use, excellent durability In addition, it is an object of the present invention to provide a clamping device having a new structure that is excellent in stability by being supported at a plurality of points, and can be variously used for not only a horizontal profile but also a vertical profile or an inclined profile.

4. In addition, the guide member facilitates the insertion of the first clamping element and the second clamping element into the slot and at the same time supports the clamping device to further improve the stability.

5. It is also provided with a non-slip member which absorbs vibrations and shocks while preventing slipping by elastically pressing contact with the upper surface of the profile plate while the clamping element is caught and fixed inside the slot opening of the profile plate. Since the base member and the injection molding are integrally provided, the non-slip member can be prevented from being detached by frequent use.

6. In addition, in the conventional technology, there was a problem that the lever shaft and the lever handle are separated by frequent use of the rotary lever. By knurling both ends of the lever shaft and manufacturing the rotary lever by injection molding using the lever shaft thus processed As before, the lever shaft and the lever handle can be prevented from being detached.
