The sliding body 3 and the tension rod 1 are integrally connected with the base 4. There is a pre-tightening force between them; the limit top wire 5 is connected with the base 4 through a screw pair.

The working principle of the present invention is mainly realized by two axial movements and the opening and closing of the umbrella structure. One is the axial movement between the tension rod and the sliding body, the function is to open and close the umbrella structure, and the power source is screw drive; the other is the axial movement between the whole tension rod sliding body and the base , the function is to press the conical boss of the base and the opened umbrella-shaped structure on both sides of the orifice plate respectively to realize locking and unlocking, and the power source is a compression spring. In addition, if the power source of the above two axial moving parts is replaced with a thin linear cylinder, the present invention is more rapid and labor-saving, and can be extended to an automatic locking mechanism.

As shown in Figures 1 to 7, the rotating rocker III and the tensioning rod 1 are fixedly connected in the circumferential direction through a hexagonal section.

As shown in Figures 2 and 3, the locking function is achieved through two axial moving parts and the opening and closing of the umbrella structure 302; one is the axial movement between the tension rod 1 and the sliding body 3, and the power source is Screw drive; the other part is the axial movement between the whole sliding body 3 of the tension rod 1 and the base 4 , and the power source is the compression spring 2 .

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , the embodiment of the present invention includes an orifice plate I, a locking mechanism II and a rotating crank handle III; the orifice plate I is the locking object of the present invention, the locking mechanism II is the content of the invention, and the rotating crank handle III is The special tool used in the locking and unlocking process of the present invention can be removed after the operation.

The tension rod 1 can rotate relative to the sliding body 3 by rotating the crank handle III. Due to the action of the thread, the tension rod 1 and the sliding body 3 move axially, and the ball of the tension rod 1 can open the umbrella structure 302 or Restoration; the function of the limiting shaft shoulder 101 is to prevent the umbrella-shaped structure 302 from being overstretched and damaged. The combination of the tension rod 1 and the sliding body 3 can move axially along the base 4 in the guide groove 401 , and the compression spring 2 is compressed or extended at the same time of movement. The function of the limiting top wire 5 is to limit the axial position of the sliding body 3, and after the umbrella-shaped structure 302 is stretched, the locking is realized.

In the embodiment of the present invention, the outer diameter of the base 4 is 100 mm, the spherical diameter of the tension rod 1 is 22 mm, and the wall thickness of the umbrella structure 302 is 1.5 mm. Lock on the perforated plate.

The working process of the present invention is as follows: first, ensure that the umbrella-shaped structure 302 is in an unstretched state, pass the umbrella-shaped structure 302 of the locking mechanism II through the hole plate I to be locked and fixed, and the three cone-shaped structures of the base 4 The boss is in contact with the hole plate surface I at the same time, as shown in Figure 2.

Next, keep the base 4 still, rotate the limiter screw 5, push the sliding body 3 to move in the direction of the hole plate I, and compress the compression spring 2. The degree of compression of the compression spring 2 determines the final locking force.

Then, keep the base 4 still, connect the rotating handle III with the hexagonal head at the end of the tension rod 1, rotate the rotating handle III, and make the tension rod 1 ball stretch the umbrella-shaped structure 302. The diameter of the umbrella-shaped structure 302 is larger than the diameter of the hole in the hole plate I.

Finally, remove the rotating rocker III, keep the base 4 stationary, rotate the limiting top wire 5 to release the compression spring 2, and the umbrella-shaped structure 302 is in contact with the orifice plate I. At this time, the two sides of the orifice plate I are the bases respectively. 4, the three conical bosses and the umbrella-shaped structure 302, due to the action of the compression spring 2, there is a pre-tightening force on both sides in contact with the orifice plate I, and the locking is completed.

To unlock, simply operate the above steps in reverse order, and reverse each step to achieve.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
