Detailed ways

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

The specific embodiment 1 of the box body of the present invention, as shown in Figures 1 to 3, the box body bottom plate 2 of the box body 1 is provided with a buckle 3 perpendicular to the box body bottom plate 2 and extending toward the outside of the box body 1, so The buckle 3 is a split structure, including two support bodies 4 fixed on the bottom plate 2 of the box body and arranged at intervals, and the two support bodies 4 are tile-shaped. Wherein two support bodies 4 constitute the support part that is used to be inserted in the fixing hole 6, and single support body 4 constitutes the split part of support part, certainly, in other embodiments, support part also can comprise three, four and so on for any number of supports 4 .

In this embodiment, an elastic body 5 with an arched middle and a "V" shape is provided on the outer arc surfaces of the two supporting bodies 4. Extend, both ends of the elastic body 5 in the insertion direction of the support body 4 are fixed on the support body 4, and the "V" shaped tip of the elastic body 5 is set towards the outside of the buckle 3, so that the elastic body 5 and the support body A triangular cavity is formed between the outer surfaces of 4. In this embodiment, for the convenience of description, the rear end of the buckle 3 is defined as the end of the buckle 3 facing the box body 1 along the insertion direction of the support body 4, and the rear end of the buckle 3 is defined as being far away from the box along the insertion direction of the support body 4. One end of the body 1 is the front end of the buckle 3, which is convenient for describing the specific embodiment of the box body of the present invention.

In this embodiment, the front wedge-shaped segment 501 is formed between the front end of the elastic body 5 and the "V"-shaped tip of the elastic body 5, and the rear wedge-shaped section is formed between the rear end of the elastic body 5 and the "V"-shaped tip of the elastic body 5. Section 502, wherein, the front wedge-shaped section 501 is provided with a guide arc surface, and one end of the guide arc surface extending toward the box body bottom plate 2 is inclined to the outside of the buckle 3 along the extension direction of the support body 4, and the rear wedge-shaped section 502 is provided with The anti-off arc surface, one end of the anti-off arc surface extending toward the bottom plate 2 of the box body is arranged obliquely to the inside of the buckle 3 along the extending direction of the support body 4 . Wherein, the front wedge-shaped section 501 constitutes a guiding portion for slidingly fitting with the fixing hole 6 to guide the deformation of the elastic body 5 so that the elastic body 5 passes through the fixing hole 6, and the rear wedge-shaped section 502 is configured for use when the box body 1 is in the installation position. It is an anti-loosening part that cooperates with the target fixing member to prevent the buckle 3 from coming out of the fixing hole 6 . Of course, in other embodiments, the number of elastic members 5 is not limited, and any number of elastic members 5 such as two, three, etc. can be set on each support body 4, and any two elastic members 5 are parallel to each other. Set and maintain a certain interval, improve the rigidity of the buckle 3, and improve the effect of preventing the buckle 3 from coming off.

In this embodiment, in order to facilitate the adaptation with the fixing hole 6, the two support bodies 4 are both tile-shaped, and the corresponding front wedge-shaped section 501 and rear wedge-shaped section 502 of the elastic body 5 are also tile-shaped, so as to improve the buckle 3 Anti-off effect, and facilitate the fixation between the support body 4 and the elastic body 5.

As shown in Figure 4 and Figure 5, when the box body 1 provided with the buckle 3 needs to be fixed on the flat plate 7, the fixing hole 6 is first drilled on the flat plate 7, and then the buckle 3 is inserted into the fixing hole 6 , when the front wedge-shaped section 501 is in contact with the wall edge of one end of the fixing hole 6, the front wedge-shaped section 501 begins to guide the deformation of the elastic body 5 on the support body 4, so that the elastic body 5 and the support body 4 are surrounded The volume of the formed cavity decreases, and as the part of the buckle 3 inserted into the fixing hole 6 gradually increases, the "V"-shaped tip of the buckle 3 contacts the edge of the fixing hole 6, and the front wedge-shaped section 501 of the elastic body 5 stops compressing , the buckle 3 directly passes through the fixing hole 6, when the "V"-shaped tip of the elastic body 5 contacts the edge of the hole wall at the other end of the fixing hole 6, the elastic body 5 loses the constraint of the hole wall of the fixing hole 6, resulting in elasticity The front wedge section 501 of the body 5 begins to recover and deform so that the volume of the cavity surrounded between the elastic body 5 and the support body 4 increases. Under the action of the elastic force, it is engaged with the edge of the hole wall of the fixing hole 6 so that the box body 1 is fixed on the flat plate 7 . Wherein, the flat plate 7 constitutes the target fixture.

In this embodiment, due to the inclined setting of the anti-off arc surface of the rear wedge-shaped section 502, the buckle 3 can adapt to a flat plate 7 with a certain thickness range, making the application of the buckle 3 more flexible. The specific thickness range is determined by the fixing hole. The aperture of 6 is related to the angle of inclination and the length of the anti-off arc surface, so it will not be described in detail here.

In other embodiments, as shown in Figure 7, the deformation of the elastic body 5 can be mainly borne by the rear wedge-shaped section 502, that is, the rigidity of the front wedge-shaped section 501 of the elastic body 5 is greater than the rigidity of the rear wedge-shaped section 502. , the thickness of the front wedge-shaped section 501 may be greater than that of the rear wedge-shaped section 502, so as to achieve the purpose of making the rigidity of the front wedge-shaped section 501 greater than that of the rear wedge-shaped section 502.

Preferably, as shown in Figure 6, the rear wedge-shaped section 502 is provided with a tooth-shaped body 503 arranged along the extending direction of the rear wedge-shaped section 502. In this embodiment, the tooth-shaped body 503 is a trapezoidal tooth, and the tooth-shaped body 503 is used for The plane facing the flat plate 7 is inclined from the outside to the inside in the insertion direction of the support body 4. When the bottom plate 2 of the box body is attached to the flat plate 7, the teeth 503 are locked under the elastic force provided by the elastic body 5. At the edge of the hole wall of the fixed hole 6 of the flat plate 7, when there is a tendency to separate between the box body bottom plate 2 and the flat plate 7, the box body bottom plate 2 cannot be separated from the flat plate 7 due to the blocking cooperation between the tooth-shaped body 503 and the flat plate 7. The space is separated, so that the buckle 3 cannot escape from the fixing hole 6, so that the fixing of the box body 1 is more firm.

Preferably, when the box body 1 is fixed by the buckle 3, it may rotate. Therefore, a positioning pin 8 is also provided on the box body bottom plate 2, and a positioning pin 8 that cooperates with the positioning pin 8 is provided on the corresponding flat plate 7. Hole 9, when installing the box body 1 on the flat plate 7, first align the positioning pin 8 with the positioning hole 9, and then insert the buckle 3 in the fixing hole 6, so that the six degrees of freedom of the box body 1 are completely Constraints, use two-point positioning to avoid the rotation of the box body 1, so that the box body 1 is fixed more firmly.
