A connection groove 7 is opened on the left side of the right moving plate 201. A moving groove 8 is opened on the front of the right moving plate 201. A connection structure 3 is arranged on the inner wall of the connection groove 7. The connection structure 3 includes a moving component 4 and a fixing component 5.

[0023] Referring to Figure 3 and 4 , the moving component 4 includes a linking block 9. The linking block 9 is arranged on the front of the right protective plate 2. The outer surface of the linking block 9 is slidably connected to the inner wall of the moving groove 8. A moving block 10 is fixedly connected to the front of the linking block 9. A linking rod 11 is arranged on the back of the linking block 9.

[0024] Adopting the above scheme: By setting the linking block 9, when the moving block 10 is toggled, the moving block 10 can drive the linking block 9 to slide leftward in the moving groove 8, so that the linking block 9 can drive the linking rod 11 to move.

[0025] Reference Figure 4 The linkage rod 11 is arranged on the inner wall of the connecting groove 7. The front surface of the linkage rod 11 is fixedly connected to the back surface of the linkage block 9. The linkage rod 11 cooperates with the fixing assembly 5 to work.

[0026] With the above scheme: By arranging the linkage rod 11, the linkage rod 11 can drive the two linkage arms 12 during the movement process, so as to drive the operation of the fixing assembly 5.

[0027] Reference Figure 4 The fixing assembly 5 includes linkage arms 12. Both of the two linkage arms 12 are arranged on the inner wall of the connecting groove 7. Linkage grooves 13 are respectively formed on the surfaces of the two linkage arms 12. The inner walls of the two linkage grooves 13 are respectively fitted with the surface of the linkage rod 11. A fixing rod 14 is arranged on the left sides of the two linkage arms 12.

[0028] With the above scheme: By arranging the linkage arms 12, when the linkage rod 11 moves, it can drive the two linkage arms 12 to move closer by squeezing the linkage grooves 13, so as to cooperate with the fixing rod 14 to drive the movement of the two fixing arms 15.

[0029] Reference Figure 4 The two ends of the fixing rod 14 are respectively fixedly connected to the upper and lower sides of the inner wall of the connecting groove 7. Two fixing arms 15 are arranged on the surface of the fixing rod 14. A fixing spring 16 is sleeved on the surface of the fixing rod 14.

[0030] With the above scheme: By arranging the fixing rod 14, the fixing rod 14 can provide the up and down stroke for the two fixing arms 15, so that the two fixing arms 15 can perform vertical sliding.

[0031] Reference Figure 4 The middles of the two fixing arms 15 are respectively slidably connected to the surface of the fixing rod 14. The two ends of the fixing spring 16 are respectively fixedly connected to the sides of the two fixing arms 15 close to each other. The right sides of the two fixing arms 15 are respectively fixedly connected to the left sides of the two linkage arms 12. Fixing blocks 17 are respectively arranged on the left sides of the two fixing arms 15.

[0032] With the above scheme: By arranging the fixing arms 15, when the two linkage arms 12 move closer, they can drive the two fixing arms 15 to slide closer on the surface of the fixing rod 14 and squeeze the fixing spring 16 to compress. The two fixing arms 15 slide and drive the movement of the two fixing blocks 17 closer.

[0033] Reference Figure 4 The two fixing blocks 17 are respectively fixedly connected to the sides of the left ends of the two fixing arms 15 away from each other. The two fixing blocks 17 are respectively inserted into the inner walls of the positioning grooves 601.

[0034] The above solution is adopted: by providing the fixing blocks 17 , the two fixing blocks 17 can be separated from the positioning grooves 601 respectively when they move closer to each other, thereby releasing the fixed limit of the positioning block 6 .

[0035] The working principle of this utility model:

[0036] When in use, move one side of the brim of the helmet to be tested to the bottom of the pressing plate 104, then the lifting arm 106 moves up and drives the fixed plate 105 to move up, and cooperates with the pressing plate 104 to clamp the brim of the helmet, then flip the protective plates 2 on both sides upward, and open the two movable plates 201 for docking, the left movable plate 201 drives the positioning block 6 to insert into the connecting groove 7, the positioning block 6 squeezes the surface of the two fixed blocks 17 respectively, so that it moves close and drives the two fixed arms 15 to slide close on the surface of the fixed rod 14, so that the two fixed arms 15 squeeze the compression of the fixing spring 16 at the same time, and then when the positioning block 6 moves to the right, the two fixed blocks 17 can be inserted into the positioning groove 601 to fix the positioning block 6. The rear lifting arm 106 continues to move upward and drives the fixed plate 105 to cooperate with the pressing plate 104 to press the safety helmet, so as to test the deformation of the safety helmet when subjected to lateral pressure. After the test is completed, the moving block 10 is pushed to the left so that the moving block 10 can drive the linkage block 9 to slide in the moving groove 8, so that the linkage block 9 synchronously drives the movement of the linkage rod 11, and the linkage rod 11 squeezes the inner walls of the two linkage grooves 13 respectively, thereby driving the two linkage arms 12 to move closer, and the two linkage arms 12 drive the two fixed arms 15 to slide closer, and drive the two fixed blocks 17 to disengage from the positioning groove 601 to release the fixed limit of the positioning block 6, and then the two moving plates 201 can be folded with the protective plate 2 respectively, and the two protective plates 2 can be lowered.

[0037] In summary: the quality inspection device for the production of labor protection products, through the coordinated work of the base 1, the protective plate 2, the connecting structure 3, the movable component 4 and the fixed component 5, solves the problem that when the lateral rigidity tester performs an extrusion test on the safety helmet, if it is not shielded, the safety helmet material may be broken by the force and cause fragments to fly, and the unshielded tester may be directly injured by the flying objects, such as scratches and cuts.
