Description

A type of anti-detachment car seat bristle strip Technical Field

[0001] This utility model relates to the field of automotive seat burr strip technology, and in particular to an anti-detachment automotive seat burr strip. Background Technology

[0002] Velcro, also known as Velcro, is an accessory used to secure car seat cushions and backrests. It is typically made from extruded special nylon material, processed through processes such as refining and slitting. Its curved die-cutting process allows it to provide secure fastening where needed, changing the traditional sponge ring-and-pin connection structure of seat covers and improving the flexibility of seat design and assembly speed.

[0003] However, in the existing technology, after prolonged use, the car seat bristles are prone to loosening or falling off the car seat due to aging and other reasons. This causes the seat cover or other car seat parts to fall off the car seat foam, which reduces the user experience and lifespan of the seat, and also reduces the practicality of the equipment. Summary of the Invention

[0004] To overcome the technical defects of existing technologies, this utility model provides a car seat burr strip that prevents it from falling off.

[0005] The technical solution adopted by this utility model is as follows: it includes a bristle strip body, with fixing blocks on both sides below the bristle strip body, and sliding rods fixedly connected to both sides at the bottom of the bristle strip body. The top of the fixing blocks is provided with a sliding groove for the sliding rods to slide. A limiting mechanism is provided on the surface of the sliding rods. The dovetail-shaped sliding rods and sliding grooves are used to initially prevent the bristle strip body from detaching and limit its movement. Then, the limiting mechanism is used to further prevent the bristle strip body from detaching and limit its movement, thereby improving the anti-detachment and limiting effect of the bristle strip body during use.

[0006] Preferably, the limiting mechanism includes a moving groove formed on the surface of the sliding rod, an adjusting groove is formed on the inner wall of the moving groove, a limiting rod is slidably connected to the inner wall of the adjusting groove near the bottom, a groove is formed at the bottom of the inner wall of the sliding groove for the limiting rod to engage, and a return spring is provided on the inner wall of the adjusting groove near the top to contact the top of the limiting rod. After the sliding rod is slid into the sliding groove, the limiting rod is then inserted into the groove formed on the inner wall of the sliding groove, thereby increasing the anti-detachment limiting effect when the equipment is in use.

[0007] Preferably, the limiting mechanism further includes an adjusting rod disposed on the limiting rod and slidably connected to the moving groove for limiting. One end of the adjusting rod is provided with an adjusting block, and the other end of the adjusting rod is provided with a limiting component. The inner wall of the adjusting groove near the top and the inner wall near the middle are provided with insertion holes. By inserting the limiting rod into the groove and then moving the adjusting rod on the limiting rod toward the insertion hole, the limiting component on the adjusting rod is moved into the insertion hole, further increasing the anti-detachment limiting effect when the equipment is in use.

[0008] Preferably, the limiting component includes an adjusting groove 2 that extends through the limiting rod near its top side for the adjusting rod to slide and limit the adjustment. The inner wall of the adjusting rod is slidably connected to a plug rod, and a connecting ring is detachably connected to one end of the plug rod away from the adjusting rod. The adjusting rod has a connecting groove that matches the connecting ring. By inserting the plug rod and the connecting ring into the plug hole, the limiting rod that is engaged in the groove is effectively limited, preventing it from detaching from the plug hole during use and thus reducing the limiting effect of the limiting rod on the sliding groove.

[0009] Preferably, a snap-fit ​​block is fixedly connected in a circumferential array on one side of the connecting ring near the connecting groove. The inner wall of the connecting groove is provided with snap-fit ​​holes for snap-fit ​​blocks to snap into. By snapping the snap-fit ​​block into the connecting groove, it is convenient for workers to quickly disassemble the detachable connecting ring on the outer contour of the plug rod, thereby increasing the efficiency of workers in disassembling and assembling the connecting ring.

[0010] Preferably, the inner wall of the connecting ring is provided with an internal thread, and the outer contour of the plug rod is provided with an external thread that matches the internal thread, so that the operator can quickly disassemble and assemble the connecting ring threaded on the outer contour of the plug rod, thereby improving the efficiency of the operator in disassembling and replacing the limit rod, the return spring and the adjusting rod.

[0011] Preferably, an anti-slip sleeve is fitted onto the outer contour of the adjusting block, and an anti-slip groove is formed on the outer surface of the anti-slip sleeve, so as to increase the anti-slip effect when the operator rotates the adjusting block.

[0012] Preferably, a rubber protective pad is adhered to the bottom of the bristle strip body, and the two sides of the bottom of the rubber protective pad are connected to the top of the fixing block, which increases the comfort of the driver and passengers sitting on the seat and avoids the problem of reduced seat comfort due to the fixing block being too hard.

[0013] The beneficial effects of this utility model are as follows: By using the fixed block, sliding rod, sliding groove, and limiting mechanism in combination, the fixed block can be quickly installed on the seat. Then, the dovetail-shaped sliding rod at the bottom of the bristle strip body slides into the dovetail-shaped sliding groove opened on the surface of the fixed block, completing the initial anti-detachment limiting of the bristle strip body. Subsequently, the limiting mechanism is used to perform secondary anti-detachment limiting of the sliding rod in the sliding groove, which effectively increases the anti-detachment effect of the bristle strip body when the seat is in use. Moreover, it is convenient for staff to quickly replace the bristle strip body after it is damaged, further increasing the practicality of the equipment. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] As shown in Figures 1-5, this embodiment provides a car seat bristle strip that prevents it from falling off, including a bristle strip body 1, fixing blocks 2 are provided on both sides of the lower part of the bristle strip body 1, sliding rods 3 are fixedly connected to both sides of the bottom of the bristle strip body 1, a sliding groove 4 is provided on the top of the fixing block 2 for the sliding rods 3 to slide, a limit mechanism is provided on the surface of the sliding rods 3, and a rubber protective pad 18 is adhered to the bottom of the bristle strip body 1, with both sides of the bottom of the rubber protective pad 18 connected to the top of the fixing block 2.

[0022] The staff first quickly installs the fixing block 2 on the seat. Then, the dovetail-shaped sliding rod 3 at the bottom of the bristle strip body 1 is slid into the dovetail-shaped sliding groove 4 on the surface of the fixing block 2, completing the initial anti-detachment limit of the bristle strip body 1. Then, the limiting mechanism is used to perform secondary anti-detachment limit on the sliding rod 3 in the sliding groove 4. The seat cover is then connected to the seat through the sliding rod 3, which effectively increases the anti-detachment effect of the bristle strip body 1 when the seat is in use. It also makes it convenient for the staff to quickly replace the bristle strip body 1 if it is damaged. In addition, the rubber protective pad 18 is used to increase the comfort of the driver and passengers when sitting on the seat, avoiding the problem that the comfort of the seat will decrease due to the material of the fixing block 2 being too hard.

[0023] The limiting mechanism includes a moving groove 5 formed on the surface of the sliding rod 3. The inner wall of the moving groove 5 is provided with an adjustment groove 6. The inner wall of the adjustment groove 6 near the bottom is slidably connected to a limiting rod 7. The bottom of the inner wall of the sliding groove 4 is provided with a groove for the limiting rod 7 to engage. The inner wall of the adjustment groove 6 near the top is provided with a return spring 8 that contacts the top of the limiting rod 7. The limiting mechanism also includes an adjustment rod 9 provided on the limiting rod 7 and slidably connected to the moving groove 5. One end of the adjustment rod 9 is provided with an adjustment block 10, and the other end of the adjustment rod 9 is provided with a limiting element. The inner wall of the adjustment groove 6 near the top and the inner wall near the middle are both provided with insertion holes 11. The limiting element includes an adjustment groove 12 that passes through the side of the limiting rod 7 near the top and is slidably connected to the adjustment rod 9. The inner wall of the adjustment rod 9 is slidably connected to an insertion rod 13. The end of the insertion rod 13 away from the adjustment rod 9 is detachably connected to a connecting ring 14. The adjustment rod 9 is provided with a connecting groove 15 that matches the connecting ring 14.

[0024] First, the fixing block 2 is installed on the seat. Then, the sliding rod 3 at the bottom of the bristle strip body 1 is slid into the sliding groove 4 on the fixing block 2, completing the initial anti-detachment limit of the bristle strip body 1. Next, the operator pulls the adjusting block 10, causing the insertion rod 13 inside the adjusting rod 9 to move outwards, so that the connecting ring 14 on the insertion rod 13 moves into the connecting groove 15 on the adjusting rod 9. This moves the connecting ring 14 out of the insertion hole 11 near the top inner wall of the adjusting groove 6. Then, the adjusting block 10 drives the adjusting rod 9 and the limiting rod 7 downwards, causing the limiting rod 7 to engage in the groove on the bottom inner wall of the sliding groove 4. Finally, the adjusting block 10 is pressed again, causing the adjusting rod 9 and the insertion rod 13 to move into the insertion hole 11 on the middle inner wall of the adjusting groove 6. The limiting rod 7 provides secondary anti-detachment limiting for the sliding rod 3 within the sliding groove 4. The seat cover is then connected to the seat via the sliding rod 3, effectively increasing the anti-detachment effect on the bristle strip body 1 during seat use. This also facilitates quick replacement of damaged bristle strip bodies 1 by staff. Furthermore, because the insertion rod 13 and connecting ring 14 are engaged in the insertion hole 11 on the inner wall of the middle of the adjustment groove 6, the limiting rod 7 is prevented from loosening and falling off during use. Simultaneously, after the connecting ring 14 falls out of the insertion hole 11 inside the middle of the adjustment groove 6, and the limiting rod 7 disengages from the groove at the bottom of the inner wall of the sliding groove 4, the returning spring 8 can quickly reset and move the limiting rod 7 back to the groove at the bottom of the inner wall of the sliding groove 4, thereby increasing the limiting and anti-detachment effect during equipment use.

[0025] A snap-fit ​​block 16 is fixedly connected in a circumferential array on one side of the connecting ring 14 near the connecting groove 15. The inner wall of the connecting groove 15 is provided with snap-fit ​​holes 17 for snap-fit ​​blocks 16 to snap into. The inner wall of the connecting ring 14 is provided with internal threads. The outer contour of the plug rod 13 is provided with external threads that are compatible with the internal threads. The outer contour of the adjusting block 10 is fitted with an anti-slip sleeve 19. The outer surface of the anti-slip sleeve 19 is provided with anti-slip grooves.

[0026] By pulling the adjusting block 10, the insertion rod 13 inside the adjusting rod 9 is moved outward, causing the connecting ring 14 on the insertion rod 13 to move into the connecting groove 15 opened on the adjusting rod 9. This causes the locking block 16 on the connecting ring 14 to engage with the locking hole 17 opened on the inner wall of the connecting groove 15. Then, rotating the adjusting block 10 causes the connecting ring 14 on the insertion rod 13 to rotate, causing the connecting ring 14 to separate from the insertion rod 13. Then, the limiting rod 7, the return spring 8, and the adjusting rod 9 are removed from the adjusting groove 6. The return spring 8 can then be replaced, increasing the efficiency of the staff in replacing the damaged return spring 8 and improving the practicality of the equipment.

[0027] The implementation principle of the anti-detachment car seat bristle strip in this application embodiment is as follows: First, the fixing block 2 is installed on the seat. Then, the sliding rod 3 at the bottom of the bristle strip body 1 is slid into the sliding groove 4 opened on the fixing block 2 to complete the initial anti-detachment limit of the bristle strip body 1. Then, the worker pulls the adjusting block 10 to move the insertion rod 13 in the adjusting rod 9 outward, so that the connecting ring 14 on the insertion rod 13 moves into the connecting groove 15 opened on the adjusting rod 9, and then the connecting ring 14 is moved out from the insertion hole 11 opened near the top inner wall of the adjusting groove 6. Then, the adjusting block 10 drives the adjusting rod 9 and the limiting rod 7 to move downwards, so that the limiting rod 7 engages in the groove opened in the inner wall of the bottom of the sliding groove 4. Then, the adjusting block 10 is pressed again to drive the adjusting rod 9 and the plugging rod 13 to move into the plugging hole 11 in the middle of the inner wall of the adjusting groove 6. Thus, the limiting rod 7 performs a secondary anti-detachment limit on the sliding rod 3 in the sliding groove 4. Then, the seat cover is connected to the seat through the sliding rod 3, which effectively increases the anti-detachment effect of the bristle strip body 1 when the seat is in use, and also makes it convenient for staff to quickly replace the damaged bristle strip body 1.
