Description

TECHNICAL FIELD

[0001] The application relates to the technical field of baby carriage accessories, in particular to a quick detachable fixing buckle for a baby carriage seat. BACKGROUND

[0002] In the prior art, the fixing method of the baby carriage seat often has the following disadvantages: 1. The traditional fixing method is inconvenient to disassemble: most baby carriage seats are fixed on the frame by screws, bolts and the like. Although this fixing method is firm, it is relatively cumbersome to operate when disassembling, and tools are needed to tighten or loosen the screws, which is time-consuming and laborious. For example, when the seat needs to be cleaned or replaced, the disassembly process will become very troublesome. 2. Some quick disassembly mechanisms have defects: although some quick disassembly mechanisms in the prior art improve the disassembly efficiency to some extent, they still have some problems. For example, the structure of some quick disassembly mechanisms is complex, and there are many parts, which are prone to failure, and may become loose or jammed after long-term use. Some quick disassembly mechanisms need multiple steps when disassembling, which is not convenient. Therefore, a quick detachable baby carriage seat fixing buckle is needed to improve the convenience of use. SUMMARY

[0003] The purpose of the application is to provide a fixing buckle that is simple in structure, easy to operate and quick to disassemble and assemble, so as to realize quick disassembly and assembly of the baby carriage seat and improve the convenience of use.

[0004] The technical solution of the application is: a quick detachable fixing buckle, characterized in that it comprises:

[0005] The buckle has a buckle seat at one end and a buckle free end at the other end.

[0006] The locked structure is formed on the buckle free end.

[0007] The locking mechanism is arranged on the buckle seat and comprises a lock connection structure and an elastic deformation part which are in clamping cooperation with the locked structure, and is used to cooperate with the locked structure to realize quick locking and unlocking.

[0008] The unlocking piece is formed on the elastic deformation part, and the elastic deformation part drives the locked structure to move away from the lock connection structure or drives the lock connection structure to move away from the locked structure by operating the unlocking piece, so as to realize quick disassembly and assembly.

[0009] One of the further technical solutions of the application is that the locked structure comprises tabs protruding from both sides of the buckle free end and barbs formed on the outer side surfaces of the tabs.

[0010] The locking structure has an opening slot for the locked structure to extend into, and a locking step is formed on the slot wall for the hook of the locking structure to be arranged.

[0011] The elastic deformation component is formed on the slot wall of the opening slot of the buckle seat and corresponds to the mounting position of the hook.

[0012] The unlocking piece is formed on the exposed surface of the elastic deformation component; pressing the unlocking piece makes the elastic deformation component extrude the hook of the locked structure inward, drives the hook to move inward, and makes it disengage from the locking step, thereby achieving unlocking.

[0013] The second further technical solution of the application is that the buckle seat has a guide slot that slidably cooperates with the two side edges of the free end of the buckle; the free end of the buckle passes through the guide slot and is locked with the locking mechanism.

[0014] One end of the elastic deformation component is fixed on the buckle seat, and the other end is a free end.

[0015] The locked structure is a reverse tooth formed on the inner side surface of the free end of the buckle; the locking structure is a locking tooth that cooperates with the reverse tooth, and the locking tooth is formed on the elastic deformation component; the locked structure is locked with the locking mechanism through the engagement of the reverse tooth and the locking tooth.

[0016] The unlocking piece protrudes outward from the buckle seat and is convex on the free end of the elastic deformation component; pressing the unlocking piece makes the elastic deformation component move inward, drives the locking tooth to move inward, and makes it disengage from the reverse tooth, thereby achieving unlocking.

[0017] The outer side surface of the free end of the buckle has an anti-slip pushing part.

[0018] Further, the buckle, the locked structure, the locking structure, the elastic deformation component, and the unlocking piece of the fixed buckle are an integrally formed structure and are made of a plastic material with certain flexibility. Preferably, the material of the fixed buckle can be POM or PA, etc.

[0019] Compared with the prior art, the application has the following advantages: through the design of the locked structure, the locking mechanism, and the unlocking piece, the disassembly and assembly process is more convenient and fast, which is suitable for frequent disassembly and assembly scenarios. The overall structure is simple and convenient to operate, can realize the quick disassembly and assembly of the seat of the child car, and improves the use convenience.
