Description
Technical Field
[0001] The utility model relates to a box body, in particular to a box body with a swing buckle box cover. Background Art
[0002] There is a type of box body currently on the market, which uses a snap hook set on the upper edge of the opening of the box body and a snap hole set on the box cover as a combined fixing piece. The snap hook and the snap hole are positioned relative to each other and then slide relatively, so that the two are snapped together to complete the combination of the box body and the box cover.
[0003] In order to make the box body and the box cover firmly assembled and prevent them from falling off, a slightly interference fit buckle hook and buckle hole are usually designed as the assembly part. When such a box body is subjected to a large temperature difference, the assembly tightness may be insufficient due to material deformation, or the assembly part may be too tight to be assembled;
[0004] In addition, during the peak business season, when such boxes are used as packaging boxes, assembly line assemblers need to assemble a large number of boxes in a short period of time. During the short and high-intensity assembly process, the above-mentioned combination fixings need to be deliberately aligned when assembled, which may cause delays in the assembly process. The snap hooks may break or the snap mouths may be damaged due to inadequate sliding assembly action or excessive sliding force used during the assembly process, which may affect the appearance of the box and the commercial value of the packaging decoration. Summary of the invention
[0005] The utility model aims to provide a box body with a swing buckle box cover, which has a reliable locking effect, and the buckle hooks and buckle holes as a combined part do not need to be arranged with interference fit, so the assembly is flexible and the fixing effect is good.
[0006] In order to achieve the above purpose, the utility model is implemented by the following technical means:
[0007] A box body with a swing-buckle box cover comprises a box body and a box cover, wherein the box body is provided with at least one pair of snap hooks, and the box cover is provided with at least one pair of snap holes, each snap hook is inserted through the insertion hole end of the corresponding snap hole and slides toward the snap end to be matched and snapped, so that the snap hook can only translate toward one side of the insertion hole end, and it is also provided with at least one pair of swing buckles, the rotating buckle pieces of the swing buckles swing forward along the hinge axis, so that the recessed buckle position of each rotating buckle piece abuts against the back of the hook of the corresponding snap hook, and stops the snap hook from translating toward the insertion hole end; the rotating buckle pieces of the swing buckles swing in the opposite direction along the hinge axis, and each rotating buckle piece does not interfere with the snap hook, and each snap hook slides toward the snap end along the insertion hole end of the corresponding snap hole, so that the snap hook and each snap hole are released from snapping.
[0008] Furthermore, a snap-fitting position is provided at the most concave part of the concave snap-fitting position, and the concave snap-fitting position abuts against the back side of the corresponding snap-fitting hook and makes the snap-fitting position snap-fit with the edge of the back side of the hook.
[0009] Furthermore, the recessed buckle position is a V-shaped recessed buckle position.
[0010] Furthermore, the snap-fit hook is an L-shaped snap-fit hook, and the vertical projection area of the insertion hole end is larger than the vertical projection area of the L-shaped snap-fit hook.
[0011] Furthermore, a gradually narrowing transition section is provided between the insertion hole end and the buckling end.
[0012] Furthermore, a stop portion is provided on the box cover. When the rotating buckle pieces of the swing buckle swing to the stop portion along the hinge axis, each rotating buckle piece does not interfere with the buckling hook, and each buckling hook slides toward the buckling end along the insertion hole end of the corresponding buckling hole, so that the buckling hook and each buckling hole are released from buckling.
[0013] Furthermore, an upper plate is provided on the box cover, and recesses are provided in the edge of the upper plate and the areas near each buckling hole, and the inner side wall of each recess forms a stopper, and the rotating buckle piece of each swing buckle swings in the opposite direction along the hinge axis into the recess.
[0014] Furthermore, the box body is formed by combining a box bottom, a box side wall, and an upper box edge. The snap hook is arranged on the upper edge of the box side wall. The snap hook is fitted and fixed in the insertion hole of the upper box edge, and the hook part of the snap hook is exposed on the upper surface of the upper box edge.
[0015] Furthermore, the box side wall is provided with at least one elastic bending portion, and the elastic bending portion is arranged at the corner portion of the box body. The box side wall is fixed by plugging in the lower plug-in block, the upper plug-in block and the lower plug-in hole of the box bottom and the upper plug-in hole of the upper box edge.
[0016] Furthermore, the elastic bending portion is provided with at least two groups of first-type notches and second-type notches arranged in sequence with each other, at least two uncut first notch joints are left in the middle of the first-type notches, at least two uncut second notch joints are left in the middle of the second-type notches, and the first and second notch joints are not located on the same straight line.
[0017] The utility model has at least the following benefits:
[0018] 1. By setting a swing buckle as an auxiliary assembly part, the rotating buckle piece is swung forward along the hinge axis, so that the concave buckle position of each rotating buckle piece abuts against the back of the corresponding buckle hook, and stops the buckle hook from moving toward the insertion hole end; based on this setting, the buckle hook and the buckle hole do not need to be arranged in a manner of close fit with each other, so the defects of insufficient assembly tightness of the buckle hook and the buckle hole, or too tight assembly parts that are difficult to assemble due to material deformation caused by thermal expansion and contraction of the material are avoided; and the assembler is more flexible when assembling the box body, and does not need to deliberately align the position, which is conducive to a box body assembly process with high strength in a short time;
[0019] 2. The recessed buckle position is set to be a V-shaped recessed buckle position. Through this setting, while not hindering the rotating buckle piece from swinging in the positive direction along the hinge axis to the edge of the back side of the snap hook at the snap-fit position, the most concave snap-fit position can have a deeper recessed amplitude, so the snap-fit position can provide a better snap-fit effect.
[0020] 3. By arranging a stopper on the upper plate, the box cover can maintain a high degree of flatness and can reduce the accidental falling off of the single edge-shaped stopper. By cutting the upper plate to form recesses, the inner wall of each recess can form a stopper, and the rotating buckle can be swung in the opposite direction along the hinge axis and moved into the recess, thereby reducing the accidental engagement of the rotating buckle and the snap hook due to accidental touch during assembly.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling readers to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details. Example
[0025] like Figure 1-3 As shown, a box body with a swing buckle 3 cover plate includes a box body made of wood and a box cover 21. The box body is formed by a box side wall 11, a box bottom 12, and an upper box edge 13. The box side wall 11 is provided with four groups of elastic bending parts 15, and the lower edge of the box side wall 11 is provided with a plurality of lower plug-in blocks, and the upper edge of the box side wall 11 is provided with a plurality of upper plug-in blocks 112 and two pairs of L-shaped buckle hooks 111.
[0026] The elastic bending portion 15 is provided with a plurality of groups of first-type notches 151 and second-type notches 152 arranged in sequence with each other. At least two uncut first notch joints 153 are left in the middle of the first-type notches 151, and at least two uncut second notch joints 154 are left in the middle of the second-type notches 152. The first and second notch joints (153, 154) are not located on the same straight line. The box side wall 11 is bent and enclosed along the elastic bending portion 15 to form a frame structure, and the corner portion of the box body is formed by bending along the four elastic bending portions 15. Then, the lower plug-in block and the lower plug-in hole of the box bottom 12, the upper plug-in block 112 and the upper plug-in hole of the upper box edge 13 are plugged and fixed, and the buckle hook 111 is fitted and fixed in the plug-in hole of the upper box edge 13, and the hook portion of the buckle hook 111 is exposed on the upper surface of the upper box edge 13, so as to form the box body.
[0027] Correspondingly, the box cover 21 is provided with four snap-fitting holes 20 matched with the snap-fitting hooks 111, and the vertical projection area of the insertion hole end 201 of the snap-fitting hole 20 is larger than the vertical projection area of the L-shaped snap-fitting hook 111. An upper plate 21 is provided above the box cover 21 in the area enclosed by the snap-fitting holes 20, and recesses 23 are provided at the edge of the upper plate 21 and in the vicinity of each snap-fitting hole 20. The inner side wall of each recess 23 forms a stopper 231, and a swing buckle 3 is provided in each recess 23. The hinge shaft 31 of the swing buckle 3 is fixed to the box cover 21 and the rotating buckle plate 32 is axially connected to the hinge shaft 31. The rotating buckle plate 32 can be swung forward and backward along the hinge shaft 31 by moving the rotating buckle plate 32.
[0028] When the rotating buckle 32 is moved along the hinge shaft 31 to the stopper 231, the rotating buckle 32 is located in the recess 23, and the assembler can place each buckle hook 111 into the insertion hole end 201 of each buckle hole 20, so that the box cover 21 is placed on the upper box edge 13. At this time, each rotating buckle 32 does not interfere with the buckle hook 111. Therefore, when the box cover 21 is translated relative to the box body, each buckle hook 111 slides along the insertion hole end 201 of the corresponding buckle hole 20 to the buckle end 203 and is matched and buckled. The hooking fit of 203 restricts the snap hook 111 from vertical movement, and it can only translate toward the insertion hole end 201 in the horizontal direction; to avoid this translation, the rotating snap plate 32 is moved to swing forward along the hinge shaft 31, so that the recessed snap position 33 of each rotating snap plate 32 abuts against the back of the corresponding snap hook 111. At this time, the rotating snap plate 32 stops the snap hook 111 from translating toward the insertion hole end 201, so that the snap hook 111 and the snap hole 20 cannot move relative to each other, so a mutually fixed structure is formed between the box cover 21 and the box body. When it is necessary to release the fixation between the box cover 21 and the box body, the rotating buckle 32 is moved again to swing in the opposite direction along the hinge shaft 31, so that each rotating buckle 32 is moved back into the recess 23. At this time, each rotating buckle 32 does not interfere with the snap hook 111, and then the operator can slide each snap hook 111 along the insertion hole end 201 of the corresponding snap hole 20 toward the snap end 203, so that the snap hook 111 and each snap hole 20 are released from snapping, and the box cover 21 can be opened again. The opening and closing process of the box body is convenient to operate, and based on this structure, the snap hook 111 and the snap hole 20 do not need to be arranged in a manner of close fit with each other, thereby avoiding the deformation of the material due to thermal expansion and contraction, resulting in the defects of insufficient assembly tightness of the snap hook 111 and the snap hole 20, or the combined part is too tight and difficult to combine; based on this, a gradually narrowing transition section 202 can be provided between the insertion hole end 201 and the snap end 203. Through this arrangement, the vertical projection area of the insertion hole end 201 is larger than the vertical projection area of the hook part of the snap hook 111, so the assembler does not need to deliberately align when assembling the box body, which is conducive to a high-intensity box body assembly process in a short time.
[0029] In order to further improve the fastening effect of the concave buckle position 33 on the buckle hook 111, in this embodiment, a snap-fit position 34 is provided at the most concave part of the concave buckle position 33. When the concave buckle position 33 abuts against the back of the corresponding buckle hook 111, the snap-fit position 34 snaps with the edge of the back of the hook. The snap-fitting of the snap-fit position 34 with the edge can effectively prevent the concave buckle position 33 from swinging in the opposite direction around the hinge shaft 31 when subjected to an unexpected external horizontal force, so that the cooperation between the rotating buckle piece 32 and the buckle hook 111 can be more secure. More preferably, the concave buckle position 33 is provided as a V-shaped concave buckle position 33. Through this setting, while not hindering the rotating buckle piece 32 from swinging forward along the hinge shaft 31 to the edge of the back of the buckle hook 111 at the snap-fit position 34, the most concave snap-fit position 34 can have a deeper concave range, so the snap-fit position 34 can provide a better snap-fitting effect.
[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
