[0005] In view of the deficiencies of the prior art, the utility model provides a reusable mobile positioning block, which solves the technical problem that the existing device is not convenient to adjust.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model is realized through the following technical solutions:

[0008] A reusable mobile positioning block includes a fixture housing;

[0009] The upper end of the fixture housing is symmetrically and fixedly installed with a moving mechanism;

[0010] The moving mechanism includes a first scissor lift. The upper end of the fixture housing is fixedly installed with a second scissor lift. The upper end of the fixture housing is fixedly installed with a plurality of electric locking switches, and each electric locking switch is respectively connected to the first scissor lift and the second scissor lift. The moving mechanism further includes a silica gel soft pad positioning block, a first chute, a first limiting groove, a second chute, a second limiting groove, a first limiting block, a first slider, a second limiting block, and a second slider.

[0011] Preferably, the silica gel soft pad positioning block is slidably installed at the upper end of the fixture housing. The silica gel soft pad positioning block is located between the first scissor-type extensors. Two first chutes are symmetrically opened on the side wall of the silica gel soft pad positioning block. Each group of first limiting grooves is opened on the inner wall of the first chute. The second chute is opened on the surface of the silica gel soft pad positioning block. The second chute is on the same side as the second scissor-type extensor. Two second limiting grooves are opened on the inner wall of the second chute. Each first limiting block is slidably installed inside the first limiting groove. Two first sliders are fixedly installed between the first limiting blocks.

Detailed implementation manners

[0022] In the embodiments of the present application, by providing a reusable mobile positioning block, the technical problem that the existing device is not convenient for adjustment is effectively solved. By arranging the first scissor-type telescopic machine and the second scissor-type telescopic machine and connecting them to the silicone soft pad positioning block, the silicone soft pad positioning block can be made parallel in the left-right and front-back directions. At the same time, by arranging an electric locking switch, the displacement of the silicone soft pad positioning block after movement and fixation can be avoided, which is convenient for the subsequent alignment and installation of the LCD module.

When the second scissor-type telescopic machine pushes the silicone soft pad positioning block, the first limiting block and the first slider will slide in the first limiting groove and the first sliding groove, thereby avoiding the left-right deviation of the first scissor-type telescopic machine and the second scissor-type telescopic machine, and at the same time ensuring the stability of the movement of the silicone soft pad positioning block.

[0023] Embodiment

[0024] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiments of the present application effectively solves the technical problem that the existing device is not convenient for adjustment. The general idea is as follows:

[0025] Aiming at the problems existing in the prior art, the present utility model provides a reusable mobile positioning block, including a fixture housing 11;

[0026] A moving mechanism is symmetrically and fixedly installed at the upper end of the fixture housing 11;

[0027] The moving mechanism includes a first scissor-type telescopic machine 12. A second scissor-type telescopic machine 13 is fixedly installed at the upper end of the fixture housing 11. A plurality of electric locking switches 14 are fixedly installed at the upper end of the fixture housing 11. Each electric locking switch 14 is respectively connected to the first scissor-type telescopic machine 12 and the second scissor-type telescopic machine 13. The moving mechanism further includes a silica gel soft pad positioning block 15, a first sliding groove 16, a first limiting groove 17, a second sliding groove 18, a second limiting groove 19, a first limiting block 21, a first slider 22, a second limiting block 23 and a second slider 24. By arranging the first scissor-type telescopic machine 12 and the second scissor-type telescopic machine 13 and connecting them to the silica gel soft pad positioning block 15, the silica gel soft pad positioning block 15 can be made parallel in the left-right and front-back directions. At the same time, by arranging the electric locking switches 14, displacement of the silica gel soft pad positioning block 15 after moving and fixing can be avoided, which is convenient for subsequent alignment and installation of the LCD module.

[0028] The silica gel soft pad positioning block 15 is slidably installed at the upper end of the fixture housing 11. The silica gel soft pad positioning block 15 is located between the first scissor-type extensors 12. Two first chutes 16 are symmetrically formed on the side wall of the silica gel soft pad positioning block 15. Each group of first limiting grooves 17 is formed on the inner wall of the first chute 16. The second chute 18 is formed on the surface of the silica gel soft pad positioning block 15. The second chute 18 is on the same side as the second scissor-type extensor 13. Two second limiting grooves 19 are formed on the inner wall of the second chute 18. Each first limiting block 21 is slidably installed inside the first limiting groove 17. Two first sliders 22 are fixedly installed between the first limiting blocks 21. Two first sliders 22 are slidably installed in the first chute 16. Two first sliders 22 are fixedly installed on the output shafts of the first scissor-type extensors 12. Two second limiting blocks 23 are slidably installed inside the second limiting grooves 19. The second slider 24 is fixedly installed between the second limiting blocks 23. Two second sliders 24 are slidably installed in the second chute 18. Two second sliders 24 are fixedly installed on the output shafts of the second scissor-type extensors 13. When the first scissor-type extensors 12 and the second scissor-type extensors 13 push the silica gel soft pad positioning block 15 to move back and forth, in order to prevent the first scissor-type extensors 12 and the second scissor-type extensors 13 from shifting left and right, by providing the first limiting grooves 17 and the first chutes 16 and the second chutes 18 and the second limiting grooves 19, when the first scissor-type extensors 12 push the silica gel soft pad positioning block 15, the second limiting blocks 23 and the second sliders 24 on the second scissor-type extensors 13 move in the second limiting grooves 19 and the second chutes 18. When the second scissor-type extensors 13 push the silica gel soft pad positioning block 15, the first limiting blocks 21 and the first sliders 22 will slide in the first limiting grooves 17 and the first chutes 16, thereby preventing the first scissor-type extensors 12 and the second scissor-type extensors 13 from shifting left and right, and at the same time ensuring the stability of the silica gel soft pad positioning block 15 during movement.

[0029] Working principle:

[0030] First step, when it is necessary to move in the direction away from the second scissor-type extensor 13, first, the second scissor-type extensor 13 can be activated, so that the second scissor-type extensor 13 pushes the second limiting block 23 and the second slider 24 in the direction away from the second scissor-type extensor 13, thereby generating a radial force to push the silica gel soft pad positioning block 15 to move in the direction away from the second scissor-type extensor 13. At the same time, during the movement of the silica gel soft pad positioning block 15, the first limiting grooves 17 and the first chutes 16 will slide with the first limiting blocks 21 and the first sliders 22.

[0031] Step 2: When it is necessary to move the first scissor lift 12 forward and backward (the forward and backward movement of the first scissor lift 12 is to move in the direction of a certain first scissor lift 12 respectively), first, the first scissor lift 12 can be directly activated, so that the first scissor lift 12 pushes the second limit block 23 and the second slider 24 to move towards the side where the first scissor lift 12 is not activated, thereby pushing the silicone soft pad positioning block 15 to move towards the side where the first scissor lift 12 is not activated. At this time, the first scissor lift 12 on the unactivated side will be compressed, and at this time, the second chute 18 and the second limit groove 19 will slide with the first slider 22 and the first limit block 21. When the adjustment is completed, the electric lock switch 14 can be activated at this time to lock the first scissor lift 12 and the second scissor lift 13.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
