Technical realization elements of expansion screw installation device for military equipment

Technical implementation elements:

4. The purpose of this utility model is to provide a kind of expansion screw installation device for military equipment, so as to solve the problem that the expansion screw proposed in the above-mentioned background technology often needs to be beaten with the help of a common hammer or an electric During the process, the body of the staff will be injured due to improper operation, and the process of knocking and beating will also cause damage to the parts other than the installation part of the expansion screw.

5. In order to achieve the above purpose, the present utility model provides the following technical solutions: an expansion screw installation device for military equipment, comprising a main body case, and a No. It is rotatably connected with the main body box, the middle part of the No. 1 rotating rod is connected with a half gear through the slot key, the lower ends of the two sides of the main body box are provided with a moving column, and the upper end of the moving column is fixedly provided with a rack, and the rack passes through The teeth and the half gears mesh with each other, the inner wall of the rear end of the main body is rotatably connected with a No. 2 rotating rod, one end of the No. 2 rotating rod is provided with a rocker, and the rocker is rotatably connected with the No. 2 rotating rod. A spring telescopic rod is arranged along one side of the inside of the main body box, and the spring telescopic rod and the rocker are rotatably connected through a rotating shaft, the other end of the spring telescopic rod is provided with a No. , the other end of the No. 1 swivel base is provided with a limit block, and the No. 1 swivel base is fixedly connected to the upper side of one end of the limit block, the upper side of the other end of the limit block is welded with a connecting plate, and the upper end of one side of the connecting plate is A compression spring is fixedly connected, the other end of the compression spring is fixedly connected with the inner wall of the main body box, the middle of the other end of the limit block is provided with a No.

6. Preferably, one end of the limiting block is engaged with the rack.

7. Preferably, a No. 1 swing rod is fixedly connected with a No. 1 swing rod along both ends of the outer wall of the main body box, and an anti-skid handle is fixedly connected to the upper ends of the two No. 1 swing rods.

8. Preferably, sliding bars are fixedly connected on both sides of the rack, and the inner walls on both sides of the main body box are provided with matching sliding bars.

The matching slideway, and the slide bar is slidably connected with the slideway.

9. Preferably, the top of the front end of the rack is provided with a fixed frame, and the fixed frame is fixedly connected to the rack, the upper and lower sides of the fixed frame are fixedly connected to a limit spring, and the other end of the limit spring is fixed to a limit spring. plate, and the concave surfaces of the two limit plates are opposite to each other.

10. Preferably, the lower end of the main body box is provided with a hinge, the other end of the hinge is rotatably connected to a handle, and the outer wall of the handle is sleeved with a non-slip pad.

11. Compared with the prior art, the beneficial effects of the present utility model are:

12.1. In this utility model, by setting the No. 1 rotating rod, the half gear and the moving column, the No. 1 swing rod can be rotated clockwise by taking the No. 1 rotating rod as the center of rotation. At this time, the No. 1 swing rod drives the half gear to rotate clockwise. , at this time, the rack meshes with the half gears, thereby driving the moving column to move in the direction of the expansion screw, and the moving moving column continuously squeezes the expansion screw to start expanding, thereby completing the expansion installation of the expansion screw. This process is stable Extrusion of the expansion screw will neither harm the body of the staff due to improper operation, nor cause damage to the installation site of the expansion screw, which is worth promoting.

13.2. In this utility model, by setting the hinge and the handle, when the equipment is not in use, only need to rotate the handle to the bottom of the main box with the hinge as the center of rotation, thereby reducing the overall space occupied by the equipment and making it easier for the staff to This device is stored.
