Description

Technical Field

[0001] This utility model belongs to the field of seats, and specifically relates to a snap-fit ​​structure for a seat back panel. Background Technology

[0002] Most existing seat back panels have a double-layer structure: a support plate and a backrest plate. The backrest plate and support plate are stacked and installed together using a snap-fit ​​connection. Most existing snap-fits are fixed and attached to the backrest plate or support plate, which has a fastener. The snap-fit ​​engages with the fastener to secure the backrest plate to the support plate. The disadvantage of this snap-fit ​​connection method is that it is not easy to disassemble. Replacing the backrest plate or support plate requires considerable force to detach the snap-fit ​​from the fastener, making disassembly very inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a snap-fit ​​structure for a seat back panel, making it easy to disassemble the back panel and the support plate.

[0004] The seat back panel has a buckle structure including a slide and a buckle. The buckle is slidably mounted on the slide and elastically abuts against the slide. The buckle is provided with a hook extending from the slide.

[0005] The slide block has a built-in sliding cavity, and the buckle is slidably installed along the sliding cavity.

[0006] One end of the buckle is provided with a limiting platform, and one end of the sliding cavity is provided with a limiting hole. The buckle passes through the limiting hole and the limiting platform is limited to the limiting hole.

[0007] The hook is located at the other end of the buckle and is in the shape of an oblique block.

[0008] The limiting platform is provided with a first mounting post, and the inner wall of the sliding cavity is provided with a second mounting post. The first mounting post and the second mounting post are connected relative to each other by a spring, and the spring is arranged along the length direction of the buckle.

[0009] The seat back panel includes a backrest panel and a support plate. The slide is disposed on the support plate. The outer edge of the support plate is provided with a through groove perpendicular to it. The outer side of the through groove is provided with a notch. The outer edge of the backrest panel is provided with a flange plate. The flange plate is provided with a buckle groove. The flange plate is inserted into the through groove. The buckle passes through the buckle groove and is engaged with the notch groove.

[0010] The beneficial effects of this utility model are as follows: the buckle slides along the slide under the action of the spring. When the compressed spring is released and the buckle extends out of the slide, the hook will lock the backrest and the support plate in place. When the hook is pressed and retracted into the slide, the hook will disengage from the backrest and the support plate, making it easy to remove the backrest from the support plate.

[0012] Figure 2 This is an exploded view of the snap-fit ​​structure of this utility model. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] like Figure 1 , 2 As shown, the seat back panel includes a backrest panel 1 and a support panel 2. The outer edge of the support panel 2 is provided with a through groove 3 that vertically penetrates the support panel. The outer side of the through groove 3 is provided with a notch 4. The outer edge of the backrest panel 1 is provided with a flange 5. The flange 5 is provided with a buckle groove 6. The flange 5 is inserted into the through groove 3.

[0015] This snap-fit ​​structure is used to install the backrest panel onto the support plate and to remove the backrest panel from the support plate. This snap-fit ​​structure consists of a slide 7 and a snap 8. The slide 7 is distributed along the edge of the support plate 2, protrudes from the support plate 2 and forms a sliding cavity 9 inside. The length direction of the sliding cavity 9 is perpendicular to the edge of the support plate 2, and the snap 8 is slidably installed in the sliding cavity 9.

[0016] The latch 8 has a plate-shaped limiting platform 10 at its tail end and a hook 11 at its head end, which is shaped like an oblique block. The sliding cavity 9 has a limiting hole 12 at its head end, a support plate 13 on the front side of the limiting hole 12, and vertical limiting posts 14 on both sides of the rear side of the limiting hole 12. The hook 11 extends through the limiting hole 12 under the support of the support plate 13 until it is limited by the limiting platform 10 to the limiting posts 14. The limiting platform 10 has a first mounting post 15, and the inner wall of the sliding cavity 9 has a second mounting post 16. The first mounting post 15 and the second mounting post 16 are positioned opposite each other and abut against each other by a spring 17, which is positioned along the length of the latch 8. Thus, the latch 8 slides in the sliding cavity 9; when the spring 17 is compressed, the latch 8 retracts into the sliding cavity 9; when the spring 17 is released, the latch 8 extends out of the sliding cavity 9.

[0017] When the backrest panel 1 is installed with the support plate 2, the backrest panel 1 is covered along the edge of the support plate 2. The buckle 8 extends from the slide 7, and the hook 11 passes through the buckle groove 6 and engages with the notch groove 4, thereby securing the backrest panel to the support plate. When the backrest panel is disassembled from the support plate, the hook 11 is pressed from the notch groove 4, the buckle 8 retracts into the slide 7, and the limiting platform 10 compresses the spring 17. Applying the elastic force of the spring 17 to the buckle 8 allows it to extend and retract. The buckle 8 is secured by the hook 11 engaging with the buckle groove 6 and the through groove 3, thus reducing the disassembly force required to separate the hook from the buckle groove and the through groove, and facilitating the disassembly process.
