[0004] However, the following problems may occur during the use of the device: after the main connecting mechanism and the connecting nut mechanism are docked, the anti-dropping clamping mechanism needs to be operated again to fix the two for a second time, and then the clamping bolt is rotated to prevent it from falling off. The operation is relatively complicated, which increases the number of steps for the staff to install the hardware joints, and the installation efficiency is low. In view of this, we propose a hardware joint with an anti-dropping effect to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6The utility model provides a technical solution: a hardware joint with an anti-falling effect, including a main connecting mechanism 1, a connecting nut mechanism 2 is threadedly connected to the upper side of the main connecting mechanism 1, and both side surfaces of the main connecting mechanism 1 are fixedly connected with fixed blocks 3. The structures of the two fixed blocks 3 are the same, so only one fixed block 3 is described below. The interior of the fixed block 3 is hollow, and a rotating shaft 4 is rotatably sleeved inside the fixed block 3. Both ends of the rotating shaft 4 rotate and penetrate the interior of the fixed block 3. The outer surfaces of both ends of the rotating shaft 4 are sleeved with connecting rods 5. The surface of the connecting rod 5 on one side away from the main connecting mechanism 1 is fixedly connected with a horizontal plate 6. The surface of the plate 6 is fixedly connected with a fixed plate 17, and a telescopic groove 20 extending to the outside is provided inside the fixed plate 17, and a telescopic plate 21 is slidably connected inside the telescopic groove 20, and a second spring 22 is fixedly connected between the lower surface of the telescopic plate 21 and the telescopic groove 20, and two card grooves 9 are provided on the outer surface of the connecting nut mechanism 2, and the card groove 9 and the telescopic plate 21 are adapted, and two first sliding grooves 7 are provided on the upper surface of the main connecting mechanism 1, and a pressing plate 8 is slidably connected inside the first sliding groove 7, and a driving component is provided on the lower surface of the pressing plate 8. When the staff thread the main connecting mechanism 1 and the connecting nut mechanism 2, the main connecting mechanism 1 and the connecting nut mechanism 2 are screwed. The body connection mechanism 1 and the connecting nut mechanism 2 will be close to each other, and the pressing plate 8 will slide inside the first sliding groove 7 at this time. The movement of the pressing plate 8 drives the driving assembly to move, and the movement of the driving assembly drives the rotation of the rotating shaft 4. The rotation of the rotating shaft 4 drives the two connecting rods 5 to move, and the movement of the two connecting rods 5 drives the rotation of the cross plate 6. The rotation of the cross plate 6 drives the movement of the fixed plate 17. When the telescopic plate 21 contacts the surface of the connecting nut mechanism 2, it continues to rotate. At this time, the telescopic plate 21 will slide inside the telescopic groove 20, and the second spring 22 will contract. When the telescopic plate 21 is located outside the card slot 9, Relying on the elastic force of the second spring 22 itself, the telescopic plate 21 will be stuck into the interior of the card slot 9, and finally the connection and secondary fixation of the main connecting mechanism 1 and the connecting nut mechanism 2 are realized. The above structure solves the problem that some existing hardware joints are relatively complicated and have low connection efficiency when they are secondary fixed, and effectively realizes the anti-slip effect between the main connecting mechanism 1 and the connecting nut mechanism 2. There is no need for the staff to turn additional holding bolts for fixing, which reduces the staff's operating steps and makes the operation simple, thereby indirectly improving the staff's installation efficiency of the main connecting mechanism 1 and the connecting nut mechanism 2, and it is highly practical.

[0025] Furthermore, the driving assembly includes a tooth plate 12, which is fixedly connected to the lower surface of the pressure plate 8. A second sliding groove 11 is provided inside the main connecting mechanism 1, and the second sliding groove 11 is connected to the first sliding groove 7. The tooth plate 12 is slidably connected to the inside of the second sliding groove 11. A first through groove 13 is provided on the outer surface of the main connecting mechanism 1. The fixed block 3 is connected to the second sliding groove 11 through the first through groove 13. A gear 10 is sleeved on the outer surface of one end of the rotating shaft 4 located inside the fixed block 3. The gear 10 extends into the inside of the second sliding groove 11 through the first through groove 13. The gear 10 and the tooth plate 12 are meshed and connected. The movement of the pressure plate 8 drives the tooth plate 12 to slide inside the second sliding groove 11, the movement of the tooth plate 12 drives the gear 10 to rotate, and the rotation of the gear 10 drives the rotating shaft 4 to rotate, so that the telescopic plate 21 is finally inserted into the inside of the card slot 9.

[0026] Furthermore, a first spring 14 is fixedly connected between the lower surface of the tooth plate 12 and the bottom wall of the second sliding groove 11. When the tooth plate 12 moves, the first spring 14 will contract, and then the tooth plate 12 will be reset by the elastic force of the first spring 14 itself.

[0027] Furthermore, a second through groove 23 is provided on the outer surface of the fixed plate 17, and the second through groove 23 is connected to the telescopic groove 20. A driving block 24 is slidably connected inside the second through groove 23. The driving block 24 and the telescopic plate 21 are fixedly connected. When the staff needs to make the telescopic plate 21 disengage from the interior of the slot 9, the driving block 24 is pushed. At this time, the driving block 24 will slide inside the second through groove 23, and the movement of the driving block 24 drives the movement of the telescopic plate 21, so that the telescopic plate 21 is no longer located inside the slot 9, and the staff can subsequently separate the main connecting mechanism 1 and the connecting nut mechanism 2.

[0028] Furthermore, a ball groove 15 is provided on the upper surface of the pressure plate 8, and a movable ball 16 is provided in the internal movable sleeve of the ball groove 15. When the main connecting mechanism 1 and the connecting nut mechanism 2 are close to and in contact, the connecting nut mechanism 2 will contact the movable ball 16. The setting of the ball groove 15 and the movable ball 16 reduces the friction between the pressure plate 8 and the connecting nut mechanism 2, thereby ensuring the smooth operation of the device and improving the service life of the device.

[0029] Furthermore, a sealing groove 18 is provided on the upper surface of the main connecting mechanism 1, and a sealing gasket 19 is provided on the lower surface of the connecting nut mechanism 2. The sealing groove 18 and the sealing gasket 19 are adapted to each other, and the sealing between the main connecting mechanism 1 and the connecting nut mechanism 2 is improved by the setting of the sealing groove 18 and the sealing gasket 19.

[0030] Working principle:

[0031] When the hardware joint with anti-falling effect is in use, the pressing plate 8 is made to slide inside the first sliding groove 7, and the movement of the pressing plate 8 drives the driving assembly to move, and the movement of the driving assembly drives the rotation of the rotating shaft 4, and the rotation of the rotating shaft 4 drives the two connecting rods 5 to move, and the movement of the two connecting rods 5 drives the rotation of the cross plate 6, and the rotation of the cross plate 6 drives the movement of the fixed plate 17. When the telescopic plate 21 contacts the surface of the connecting nut mechanism 2, the telescopic plate 21 continues to rotate. At this time, the telescopic plate 21 will slide inside the telescopic groove 20, and the second spring 22 will contract. When the telescopic plate 21 is located outside the card slot 9, the elastic force of the second spring 22 itself will make the telescopic plate 21 stuck in the inside of the card slot 9, and finally realize the connection and secondary fixation of the main connecting mechanism 1 and the connecting nut mechanism 2.
