Description

Technical Field

[0001] The utility model relates to the technical field of household articles, in particular to a detachable cushion fixing structure. Background Art

[0002] Cushions are indispensable fabric products in the bedroom. They are comfortable to use and have irreplaceable decorative effects. Cushions are used to adjust the contact point between the human body and the seat or bed to obtain a more comfortable angle to reduce fatigue. Cushions are easy to use and flexible, so they are convenient for people to use in various occasions and environments.

[0003] Patent application No. 201520785840.3 discloses a seat cushion, which improves the problem of poor comfort of the existing seat cushions and the inability to effectively relieve fatigue after long-term use.

[0004] However, when the existing cushions are used, they are usually sewn together with the backboard or placed directly on the backboard. However, when stains appear on the cushions sewn together with the backboard, the cushions cannot be removed from the backboard, and washing directly on the backboard will wet other parts of the backboard. For cushions placed directly on the backboard, the position of the cushions will change due to the compression of the body after the user connects the cushions, and the comfort will decrease. Therefore, a detachable cushion fixing structure is provided. Utility Model Content

[0005] The main purpose of the utility model is to provide a detachable cushion fixing structure. The utility model solves the problem that the cushion body is inconvenient to disassemble and clean during use of the existing detachable cushion fixing structure by arranging a fixing clip, a threaded handle, a fixing clip, a limiting belt, a positioning block, a fixing plate, a groove and a connecting rod.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A detachable cushion fixing structure comprises a backrest plate, a placement frame and a cushion body, a fixing clip for fixing the cushion body is welded on one side of the placement frame, a threaded handle for driving a fixing block on a connecting shaft to move is threadedly connected to the outer side of the placement frame, a connecting rod for connecting a limiting clip is welded on one side of the fixing block, a limiting belt for connecting a positioning block is screwed to the outer side of the fixing clip, a groove for placing the positioning block is opened on the surface of the limiting clip, and a fixing plate for fixing the positioning block in the groove is welded on one side of the positioning block;

[0008] Furthermore, a support rod is welded on the outside of the placement rack and moves inside the backrest plate, and a connecting groove is provided inside the support rod to allow the ball bearing on the fixed rod to slide; the height of the cushion body on the placement rack can be adjusted conveniently by installing the support rod, the fixed rod, the ball bearing and the connecting groove;

[0009] Furthermore, a spring for resetting the fixing rod is welded inside the support rod; the fixing rod is reset by the installed spring;

[0010] Furthermore, the outer surface of the backing plate has a plurality of concave holes for fixing the fixing rod; the fixing rod can be easily fixed by the concave holes;

[0011] Furthermore, a sliding groove is provided on the surface of the support plate for the support rod to slide; the sliding groove facilitates the support rod to slide.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model provides a fixing clamp, a threaded handle, a fixing clamp, a limiting belt, a positioning block, a fixing plate, a groove and a connecting rod. When the cushion body is to be disassembled and cleaned, the fixing plate on the positioning block is pressed, and then the inner side of the fixing plate contacts the positioning block, and then the positioning block is moved out of the groove on the surface of the limiting clamp, and then the limiting belt is separated from the cushion body, and then the threaded handle on the placement rack drives the fixing block on the connecting shaft to move, and then the connecting rod on the fixing block drives the inner side of the limiting clamp to separate from the cushion body, and then the cushion body is removed from the placement rack, thereby facilitating the disassembly and cleaning of the cushion body.

[0014] 2. The utility model provides a support rod, a fixing rod, a ball, a concave hole, a spring, a sliding groove and a connecting groove. When the position of the cushion body on the placement rack is to be adjusted, the fixing rod in the concave hole on the surface of the back plate is pressed, and then the ball on one side of the fixing rod slides in the connecting groove opened in the support rod, and then the spring in the support rod is compressed, the fixing rod enters the inside of the support rod, and then the placement rack is pulled to move. After the adjustment is completed, the spring drives the fixing rod to pop outward, and then the fixing rod enters another concave hole on the surface of the back plate to fix the placement rack, thereby facilitating the adjustment of the height of the cushion body on the placement rack.
