Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is a three-dimensional exploded view of an embodiment of the fastening structure of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a learning chair with a fastening structure. Wherein, buckle fixed knot constructs and includes: the fixing piece comprises a fixed piece 1, a main body 2, a locking piece 3 and an elastic piece 4.

The fixed piece 1 is connected with the main body 2 through a locking piece 3 and an elastic piece 4. Wherein, the fixed part 1 can be a shell or a decorative cover. Because retaining member 3 and shell fragment 4 are independently designed by mounting 1, main part 2 relatively, so overcome the big problem of the die sinking degree of difficulty that integral type design exists among the prior art.

The fixed piece 1 and the main body 2 are integrally formed in an injection molding mode. Correspondingly, the main body 2 is provided with a cavity 21 suitable for accommodating the fixed part 1, and the shape and the size of the cavity 21 are arranged corresponding to the fixed part 1.

In order to facilitate the connection and fixation through the locking member 3 and the elastic sheet 4, a plurality of protruding assembling holes 11 are formed in the assembling surface of the fixed member 1, and the elastic sheet 4 is assembled on the end surface of the assembling holes 11 through the locking member 3. So, through setting up a plurality of pilot holes 11, when being connected by mounting 1 and main part 2, the mounted position design is more nimble. In one embodiment, the assembling holes 11 are distributed at one end, the middle and the other end of the assembling surface of the fixed member 1. The locking piece 3 can be a self-tapping screw, and a hole suitable for the self-tapping screw to penetrate through is formed in the middle area of the elastic sheet 4.

In order to enable the elastic sheet 4 to be suitable for clamping during assembly, the elastic sheet 4 is a component with a middle area arched relative to a peripheral edge area along the assembly direction, and when the elastic sheet 4 is assembled and fixed by the locking piece 3, a concave surface of the elastic sheet faces to the end surface of the assembly hole 11. Thus, when the elastic sheet 4 is compressed by an external force, it has an outward expanding elastic force to lock the fixed member 1 and the main body 2 together. In order to improve the locking effect of the clamping connection of the elastic sheet 4, a plurality of protrusions 41 are arranged on the peripheral edge of the elastic sheet 4, and the plurality of protrusions 41 are arranged at intervals in the circumferential direction. In one embodiment, the peripheral edge of the elastic sheet 4 is a sawtooth-shaped edge.

Correspondingly, the main body 2 is provided with clamping grooves 22 suitable for being matched with the elastic sheets 4, the number and the positions of the clamping grooves 22 are correspondingly arranged with the assembling holes 11, and the clamping grooves 22 are arranged in the cavity 21. When the fixed piece 1 is connected, the fixed piece is clamped in the clamping groove 22 of the main body 2 through the elastic sheet 4 assembled on the fixed piece.

To sum up, the utility model discloses a buckle fixed knot constructs will be connected through retaining member and shell fragment by mounting and main part, so overcome the big problem of the die sinking degree of difficulty that the integral type design exists among the prior art. Meanwhile, the split type design and assembly are more flexible, and the distribution mode of the connecting positions can be selected according to the actual situation. In addition, the fastening effect of integral type joint can also be played to the connected mode of adoption retaining member and shell fragment.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
