Description

Technical fields:

[0002] This utility model relates to a quick-connect buckle structure and a storage box using the quick-connect buckle structure. Background technology:

[0004] Currently, storage boxes used to hold items have a variety of structures, such as those made of multiple plastic sheets or several strips of particleboard. However, these storage boxes are poorly designed, resulting in them being easily damaged and having poor structural stability.

[0005] For example, the Chinese patent "A Conveniently Assembled Double-Layer Storage Box" (publication number CN214240225U) includes a base plate and a back plate. One end of the base plate is integrally connected to the lower end of the back plate through a first bending portion. The end faces on both sides of the back plate have first splicing portions. The end faces on both sides of the base plate have second splicing portions. The splicing of these components is achieved by interlocking the inverted trapezoidal splicing portions with openings. However, the inverted trapezoidal splicing portions are prone to damage and disengagement under certain external forces, resulting in structural instability. Summary of the Invention:

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to propose a quick-connect buckle structure and a storage box using the quick-connect buckle structure. The quick-connect buckle structure and the storage box using the quick-connect buckle structure are reasonably designed and conducive to improving the structural stability and service life of the storage box.

[0008] This utility model is implemented using the following solution.

[0009] The quick-connect buckle structure of this utility model is characterized in that: the quick-connect buckle includes a first strip block and a second strip block provided on a first side of the first strip block, and a protrusion spaced apart from the free end of the second strip block is provided on the first surface of the second strip block, and the length direction of the protrusion is parallel to and spaced apart from the first side of the first strip block.

[0010] Preferably, the first strip block and the second strip block are arranged perpendicularly, and the first surface of the second strip block is perpendicular to the first side surface of the first strip block.

[0011] Preferably, the first side of the first strip block is provided with a U-shaped block surrounding the outer periphery of the second strip block, and a hollow space is formed between the inner periphery of the U-shaped block and the outer periphery of the second strip block; the length and width of the first strip block are both greater than the length and width of the second strip block; the second strip block is thinner than the U-shaped block.

[0012] Preferably, the protrusion is disposed along the width direction of the second strip block and extends from the first surface of the second strip block to the second surface in the width direction of the second strip block.

[0013] Preferably, the cross-sectional shape of the second strip block is triangular, the base of the triangular second strip block is flush with the first surface of the second strip block, the angle between the hypotenuse of the triangular second strip block near its free end and the base is α, the angle between the hypotenuse of the triangular second strip block away from its free end and the base is b, b is greater than α, and α is less than 40 degrees.

[0014] Preferably, the cross-sectional shape of the second strip block is arched.

[0015] The present invention relates to a storage box, characterized in that: the storage box includes a base plate and a surrounding plate connected to the base plate; the surrounding plate is composed of several side plates connected end to end; each side of the base plate is provided with at least one first protrusion with a perforation; the first end of each side plate is provided with a second protrusion with a perforation; the tail end of each side plate is provided with a second slot for inserting a second protrusion of another side plate; the bottom side of each side plate is provided with a first slot for inserting a first protrusion; after the first protrusion is inserted into the first slot, the perforation of the first protrusion is exposed on the outside of the side plate, and a quick-connect buckle is inserted into the perforation of the first protrusion; after the second protrusion is inserted into the second slot, the perforation of the second protrusion is exposed on the outside of the side plate, and a quick-connect buckle is inserted into the perforation of the second protrusion.

[0016] Preferably, the base plate is rectangular, and the surrounding plate is composed of four side plates connected end to end.

[0017] Preferably, the base plate is triangular, and the surrounding plate is composed of three side plates connected end to end.

[0018] Preferably, each side of the base plate is provided with two spaced-apart first protrusions with perforations, and each side plate is provided with two first strip grooves.

[0019] The quick-connect buckle structure of this utility model is reasonably designed, which is conducive to the insertion and fixing of the storage box. Because the quick-connect buckle is inserted into the through hole of the first protrusion and the through hole of the second protrusion, the connection between the bottom plate and the side plate and the side plate and the side plate can be strengthened, which helps to reduce the damage at the connection under the action of external force and improve the service life.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model has a quick-connect buckle structure, such as Figure 1-3 As shown, the quick-connect buckle 1 includes a first strip block 2 and a second strip block 3 disposed on the first side 5 of the first strip block 2. The first strip block 2 can be a rectangle or an ellipse with chamfers, etc., and the second strip block 3 can be a rectangle with chamfers, etc. The first strip block and the second strip block can be arranged perpendicularly or not perpendicularly, and the first surface 6 of the second strip block is perpendicular or not perpendicular to the first side 5 of the first strip block.

[0031] Better, such as Figure 1 As shown, the length and width of the first strip block 2 are both greater than the length and width of the second strip block 3.

[0032] The first surface 6 of the second strip block 3 is provided with a protrusion 4 spaced apart from the free end of the second strip block. The length direction of the protrusion 4 is parallel to and spaced apart from the first side surface 5 of the first strip block. The protrusion 4 is not located at the free end of the second strip block, but at a position spaced apart from the free end of the second strip block, which makes it easier for the quick-connect buckle 1 to be inserted into the through hole A4 of the protrusion. The length direction of the protrusion 4 is parallel to and spaced apart from the first side surface 5 of the first strip block, which also facilitates the insertion of the quick-connect buckle 1 into the through hole A4 of the protrusion (including the first protrusion and the second protrusion).

[0033] To improve the support effect, a U-shaped block 7 is provided on the first side 5 of the first strip block, surrounding the outer periphery of the second strip block. A hollow spacer 8 is formed between the inner periphery of the U-shaped block and the outer periphery of the second strip block. The U-shaped block 7 can increase its contact area with the protrusions (including the first protrusion and the second protrusion), thereby improving the support effect at the connection. In addition, the hollow spacer 8 (i.e., the U-shaped groove) can make the second strip block 3 relatively independent, so that the second strip block 3 has a certain elasticity and is easy to insert into the through hole A4.

[0034] To facilitate insertion and removal, the second strip block 3 is thinner than the U-shaped block 7, i.e. Figure 3 As shown, the bottom surface of the second strip block 3 is lower than the bottom surface of the U-shaped block 7.

[0035] The protrusion 4 is arranged along the width direction of the second strip block and extends from the first surface of the second strip block to the second surface, or it can extend from the first surface of the second strip block to the second surface.

[0036] One embodiment is, as Figure 1 As shown, the cross-sectional shape of the second strip block is triangular. The base of the triangular second strip block is flush with the first surface of the second strip block. The angle between the hypotenuse of the triangular second strip block near its free end and the base is 'a', and the angle between the hypotenuse of the triangular second strip block away from its free end and the base is 'b'. b is greater than a, and a is less than 40 degrees.

[0037] One embodiment is, as Figure 2 As shown, the cross-sectional shape of the second strip block is arched.

[0038] The storage box of this utility model, such as Figure 4-6 As shown, the storage box includes a base plate A1 and a surrounding plate A2 connected to the base plate. The surrounding plate is composed of several side plates A3 connected end to end. The base plate can be rectangular and the surrounding plate can be composed of four side plates connected end to end; or the base plate can be triangular and the surrounding plate can be composed of three side plates connected end to end.

[0039] Each side of the base plate has one, two, or three first protrusions A5 with through holes A4. The first end of the side plate has a second protrusion A6 with through holes A4, and the tail end of the side plate has a second slot A7 for inserting a second protrusion of another side plate. The bottom side of the side plate has a first slot A8 for inserting the first protrusion. After the first protrusion A5 is inserted into the first slot A8, the through hole of the first protrusion A5 is exposed on the outside of the side plate (the width of the through hole A4 is greater than the sum of the thickness of the side plate and the second slot 3, and the width of the through hole A4 is less than the sum of the thickness of the side plate, the second slot 3, and the protrusion 4). The quick-connect buckle 1 is inserted into the through hole of the first protrusion A5. After the second protrusion A6 is inserted into the second slot A7 of another side plate, the through hole of the second protrusion A6 is exposed on the outside of the side plate. The quick-connect buckle 1 is inserted into the through hole of the second protrusion A6.

[0040] The quick-connect buckle structure of this utility model is reasonably designed, which is conducive to the insertion and fixing of the storage box. Because the quick-connect buckle is inserted into the through hole of the first protrusion and the through hole of the second protrusion, the connection between the bottom plate and the side plate and the side plate and the side plate can be strengthened, which helps to reduce the damage at the connection under the action of external force and improve the service life.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
