Description

Technical Field

[0001] This utility model relates to the field of snap-fit ​​structure technology, and in particular to a novel integrated spring snap-fit ​​structure. Background Technology

[0002] As society develops and cars become more and more common, people's demands for car functions are also increasing. During driving, car headrest covers provide protection for the vulnerable head and neck. Car headrest covers can be adjusted to meet the needs of drivers of different heights. Car safety headrests are divided into two types: fixed and movable. In movable headrests, a headrest guide sleeve is usually installed at the connection between the headrest pin and the seat back frame.

[0003] In the existing technology, when some guide sleeves are connected to the car backrest, it is necessary to first insert the guide sleeve into the corresponding hole of the seat back, and then use screws, nuts or other fasteners to connect the guide sleeve and the seat back. Bolt installation requires the use of tools, and the bolts are small and may be lost, which is cumbersome and increases the working time of the staff. Utility Model Content

[0004] This utility model mainly provides a new integrated spring buckle structure that facilitates improved installation efficiency and reduces installation time for workers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel integrated spring buckle structure, comprising: a backrest, the top of which has a placement groove, a guide sleeve slidably installed inside the placement groove, two slots on the top of the backrest, each slot having a slot on its inner wall, two connecting seats symmetrically arranged on the outer wall of the guide sleeve, two first springs fixedly installed on the inner wall of each of the two connecting seats, a movable plate fixedly installed at one end of each of the two first springs, a locking block and a pressure plate fixedly installed at the end of the movable plate away from the first spring, an opening penetrating through the inner wall of the connecting seat, the locking block slidably connected to the opening, one end of the pressure plate penetrating through the connecting seat and slidably connected to the connecting seat, a fixing groove at the bottom of the pressure plate, a fixing plate fixedly installed on the outer wall of the connecting seat, a second spring fixedly installed on the top of the fixing plate, a fixing block fixedly installed on the top of the second spring, and a pull plate fixedly installed on the outer wall of the fixing block.

[0006] Preferably, a connecting plate is fixedly installed on the top of the connecting seat, and a connecting groove is opened on the outer wall of the connecting plate. The outer wall of the connecting plate fits against the inner wall of the connecting port, and the outer wall of the connecting block fits against the inner wall of the connecting groove. When the connecting block enters the connecting groove, the connecting plate can be fixed.

[0007] Preferably, a top plate is symmetrically installed on the outer wall of the guide sleeve. A connection port is opened through the top of the top plate. A storage groove is opened on the inner wall of the connection port. A threaded hole is opened through the inner wall of the storage groove. A threaded rod is threadedly connected inside the threaded hole. A connecting block is movably connected to one end of the threaded rod. A handle is fixedly installed on the end of the threaded rod away from the connecting block. When the operator rotates the handle, the threaded rod rotates, causing the threaded rod to move along the threaded hole, thereby driving the connecting block to move.

[0008] Preferably, a limiting rod is fixedly installed at the bottom of the fixing block, and the bottom of the limiting rod is slidably inserted into the fixing plate to limit the fixing block and prevent the fixing block from tilting.

[0009] Preferably, the outer wall of the connector fits into the inner wall of the slot, and the outer wall of the card block fits into the inner wall of the card slot. When the card block enters the card slot, the connector can be fixed in place.

[0010] Preferably, the outer wall of the connecting block fits against the inner wall of the storage groove to prevent the connecting block from rotating when the threaded rod rotates.

[0011] Preferably, the fixing block is fitted to the inner wall of the fixing groove, so that the fixing block can be prevented from moving when it enters the fixing groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during installation, the worker first inserts the guide sleeve into the placement groove on the backrest, and then pulls the pull plate. The pull plate causes the fixing block to leave the fixing groove, and the second spring is compressed. The two connecting seats are then inserted into the two slots respectively. When the inclined surface of the locking block contacts the inner wall of the slot, the locking block is squeezed into the interior of the connecting seat. The locking block drives the pressure plate to move through the moving plate, and the first spring is compressed. When the locking block moves to the side of the slot, the locking block enters the slot under the elastic force of the first spring. The connecting seat and the guide sleeve are fixed, and the installation is completed at this time, which improves the installation efficiency. At this time, the fixing groove moves above the fixing block, and the elastic force of the second spring pushes the fixing block into the fixing groove, thus preventing foreign objects from touching the pressure plate and causing the locking block to fall out of the slot.

[0014] 2. In this utility model, when replacing the connector, the operator rotates the handle, the threaded rod rotates, causing the threaded rod to move along the threaded hole, thereby driving the connecting block away from the connecting groove. At this time, the connecting plate can be pulled out to repair or replace the connector. Finally, the connecting plate is inserted into the connecting port, the handle is rotated in the opposite direction, and the connecting block enters the connecting groove, thus completing the installation. This facilitates the repair or replacement of the connector. Attached Figure Description

[0023] like Figure 3 As shown, a connecting plate 14 is fixedly installed on the top of the connecting seat 6. A connecting groove 15 is opened on the outer wall of the connecting plate 14. The outer wall of the connecting plate 14 fits against the inner wall of the connecting port 13. The outer wall of the connecting block 19 fits against the inner wall of the connecting groove 15. When the connecting block 19 enters the connecting groove 15, the connecting plate 14 can be fixed.

[0024] like Figure 2 and Figure 3 As shown, a top plate 7 is symmetrically installed on the outer wall of the guide sleeve 2. A connection port 13 is opened through the top of the top plate 7. A storage groove 16 is opened on the inner wall of the connection port 13. A threaded hole 17 is opened through the inner wall of the storage groove 16. A threaded rod 18 is threadedly connected inside the threaded hole 17. A connecting block 19 is movably connected to one end of the threaded rod 18. A handle 20 is fixedly installed at the end of the threaded rod 18 away from the connecting block 19. When the operator rotates the handle 20, the threaded rod 18 rotates, causing the threaded rod 18 to move along the threaded hole 17, thereby driving the connecting block 19 to move.

[0025] like Figure 4 As shown, a limiting rod 26 is fixedly installed at the bottom of the fixing block 24. The bottom of the limiting rod 26 is slidably inserted into the fixing plate 21 to limit the fixing block 24 and prevent the fixing block 24 from tilting.

[0026] like Figure 2 and Figure 3 As shown, the outer wall of the connector 6 fits against the inner wall of the slot 4, and the outer wall of the locking block 11 fits against the inner wall of the slot 5. When the locking block 11 enters the slot 5, the connector 6 can be fixed in place.

[0027] like Figure 3 As shown, the outer wall of the connecting block 19 fits against the inner wall of the storage groove 16 to prevent the connecting block 19 from rotating when the threaded rod 18 rotates.

[0028] like Figure 4 As shown, the fixing block 24 fits against the inner wall of the fixing groove 22, and when the fixing block 24 enters the fixing groove 22, it can prevent the fixing block 24 from moving.

[0029] The usage and working principle of this device are as follows: During installation, the operator first inserts the guide sleeve 2 into the placement groove 3 on the backrest 1. Then, the operator pulls the pull plate 25, which causes the fixing block 24 to leave the fixing groove 22. The second spring 23 is compressed, and the two connecting seats 6 are inserted into the two slots 4 respectively. When the inclined surface of the locking block 11 contacts the inner wall of the slot 4, the locking block 11 is squeezed into the interior of the connecting seat 6. The locking block 11 drives the pressure plate 12 to move through the moving plate 10. The first spring 9 is compressed. When the locking block 11 moves to the side of the slot 5, the locking block 11 enters the slot 5 under the elastic force of the first spring 9. The connecting seat 6 and the guide sleeve 2 are fixed, and the installation is completed at this time, which improves the installation efficiency. At this time, the fixing groove 22 moves above the fixing block 24, and the elastic force of the second spring 23 pushes the fixing block 24 into the fixing groove 22. This prevents foreign objects from touching the pressure plate 12 and causing the locking block 11 to fall out of the slot 5. When replacing the connector 6, the operator rotates the handle 20, causing the threaded rod 18 to rotate and move along the threaded hole 17, thereby driving the connecting block 19 away from the connecting groove 15. At this point, the connecting plate 14 can be pulled out to repair or replace the connector 6. Finally, the connecting plate 14 is inserted into the connecting port 13, and the handle 20 is rotated in the opposite direction, causing the connecting block 19 to enter the connecting groove 15, thus completing the installation and facilitating the repair or replacement of the connector 6.
