Description

Technical Field

[0001] The utility model relates to a box body, in particular to a box body with a self-adjusting locking buckle 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] 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, resulting in 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, thus affecting the appearance of the box and the commercial value of the packaging decoration. Summary of the invention

[0004] The utility model aims to provide a box body with a self-adjusting locking buckle cover, which can make the box cover and the box body slide and be combined and fixed by self-adjusting when the box cover is tilted to the side at a small angle, thereby reducing the process of deliberately adjusting the alignment of the box cover and the box body and closing the box cover and the box body tightly.

[0005] In order to achieve the above purpose, the utility model is implemented by the following technical means:

[0006] A box body with a self-adjusting locking buckle cover, wherein an overlapping area is formed between the first plane of the box body and the second plane of the box cover, at least one pair of mutually matched turn buckles and locking holes are arranged between the first plane and the second plane, the rotation locking piece of the turn buckle is hinged to the first plane, and the locking hole is arranged on the second plane; the side edge of the rotation locking piece is expanded outward from one side of the hinge axis to the distal end; the side area of ​​the distal end of the locking hole is larger than the area of ​​the rotation locking piece, and when each rotation locking piece is sleeved in the distal end of the locking hole, each rotation locking piece can simultaneously rotate on its own axis in the distal end of the corresponding locking hole; each rotation locking piece slides along the distal end of the corresponding locking hole to the proximal side of the corresponding locking hole and is interference fit with each other; in the interference fit state, the box body and the box cover are locked with each other through a locking switch.

[0007] Furthermore, when each rotation locking piece is sleeved in the distal end of the locking hole, each rotation locking piece can simultaneously rotate within the distal end of the corresponding locking hole by ±15°.

[0008] Furthermore, the range of mutual cooperation between each rotation locking piece and the proximal end of the corresponding locking hole is not shorter than two-thirds of the length of the rotation locking piece.

[0009] Furthermore, when each rotation locking piece cooperates with the proximal end of the corresponding locking hole, the center line of each rotation locking piece coincides with the center line of the locking hole.

[0010] Furthermore, the locking switch is a fixed column arranged on the side wall of the box body, a long-axis hole locking plate slidably hinged to the fixed column, a first locking position on the first plane and a second locking position on the second plane, and the long-axis hole locking plate slides along the fixed column and engages with the first locking position and the second locking position.

[0011] Furthermore, a boss is provided at the top end of the hinge shaft, and when each rotating locking piece slides along the distal end of the corresponding locking hole to the proximal side of the corresponding locking hole, the boss abuts against the upper plane of the proximal side of the locking hole.

[0012] Furthermore, the box body is composed of a box bottom, side walls, and an upper box edge, the first plane is an upper surface of the upper box edge, and the second plane is a lower surface of the box cover.

[0013] Furthermore, at least one elastic bending portion is provided on the side wall.

[0014] Furthermore, the side wall includes an inner wall, an upper outer wall, and a lower outer wall, the elastic bending portion is arranged at the corner portion of the box body, the inner wall is fixed by a lower plug-in block, an upper plug-in block corresponding to the lower plug-in hole of the box bottom and the upper plug-in hole of the upper box edge, the upper outer wall and the lower outer wall are surrounded outside the inner wall, and the upper outer wall and the lower outer wall are buckled with each other through an upper buckling portion and a lower buckling position.

[0015] 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.

[0016] The utility model has at least the following benefits:

[0017] 1. The utility model is based on the structural setting that each rotary locking piece can simultaneously rotate its axis in the distal side of the corresponding locking hole. During the combination process of the box cover and the box body, if the rotary locking piece is slightly offset, the box cover and the box body can be self-adjusted and slid to be combined and fixed without deliberately adjusting the sleeve process of the rotary locking piece and the locking hole, thereby effectively improving the convenience of installation. In combination with the mutual locking between the box body and the box cover through the locking switch, the box body and the box cover can be stably and securely combined.

[0018] 2. By adopting a solution in which the upper and lower outer walls cooperate with the inner wall, when the inner space formed by the inner wall is filled with heavier items and the inner wall is slightly deformed along the elastic bending portion, the upper outer wall and the lower outer wall can be clamped together by the upper buckling portion and the lower buckling portion, so that the elastic bending portion of the lower outer wall and the elastic bending portion of the inner wall together form a double-layer elastic bending portion structure, which can further improve the weighing capacity of this part.

[0025] 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

[0026] like Figure 1-5As shown, a box body with a self-adjusting locking cover, wherein the box body and the box cover 2 are both made of wood, the box body is composed of a box bottom 13, a side wall 11, an upper box edge 12, and a box cover 2, a handle portion 6 is provided on the side wall 11, and is bent by four elastic bending portions 5 so that the side wall 11 can be bent along the elastic bending portions 5 and enclosed to form a side wall 11 frame, the box body is formed by combining the side wall 11 frame through a lower plug-in block 1122, an upper plug-in block 1121 corresponding to the lower plug hole 131 of the box bottom 13, the upper surface of the upper box edge 12 is used as the first plane, and the lower surface of the box cover 2 is used as the second plane. In this embodiment, the elastic bending portion 5 of the box body is structured to be provided with at least two groups of first-type notches 51 and second-type notches 52 arranged in sequence with each other, at least two uncut first notch joints 53 are left in the middle of the first-type notches 51, and at least two uncut second notch joints 54 are left in the middle of the second-type notches 52. The first and second notch joints 54 are not located on the same straight line. Based on this structure, the side wall 11 made of wood can be bent at a certain angle along the elastic bending portion 5, and the four elastic bending portions 5 correspond to the corner portions of the box body.

[0027] Since an overlapping area is formed between the box cover 2 and the upper box edge 12, the box cover 2 can cover the inner space of the box body. In order to enable the box cover 2 and the box body to be combined and fixed with each other, and to improve the convenience of assembly during the combined fixing process, two pairs of turn buckles 3 are arranged on the upper box edge 12 in this embodiment, and two pairs of locking holes are arranged in pairs on the box cover 2 as combined fixing parts. Based on the combined fixing part structure, the assembler can complete the assembly more conveniently when assembling the box body and the box cover 2.

[0028] Specifically, in this embodiment, the hinge shaft 31 is fixed to the upper box edge 12, and the rotation locking piece 32 is axially connected to the hinge shaft 31, so that the rotation locking piece 32 is hinged to the upper box edge 12; with one side of the hinge shaft 31 of the turn buckle 3 as the proximal end, the rotation locking piece 32 of the turn buckle 3 is arranged to be in an arc shape at the proximal end and the distal end, and the side edge of the rotation locking piece 32 is in a shape of expanding outward from the side of the hinge shaft 31 to the distal end, and the rotation locking piece 32 is integral and teardrop-shaped;

[0029] The locking hole 21 is provided at the corresponding position of the outer periphery of the box cover 2 and the turn buckle 3, and the area of ​​the distal side 211 of the locking hole is set to be larger than the area of ​​the rotation locking piece 32. Therefore, when each rotation locking piece 32 is sleeved in the distal end of the corresponding locking hole 21, each rotation locking piece 32 can simultaneously rotate on its axis in the distal side 211 of the corresponding locking hole. Therefore, when the box cover 2 and the box body are combined, the assembler can assemble according to this structure when assembling. In the case of a slight deviation of the rotation locking piece 32, there is no need to make special adjustments to complete the sleeve of the rotation locking piece 32 and the locking hole 21. After sliding, the side edge contour of the proximal side 212 of the locking hole is interference-fitted with the outer edge contour of the proximal end and side edge of the rotation locking piece 32, so that the box cover 2 and the box body are conveniently and securely locked. Preferably, as Figure 3-5 As shown, when each rotating locking piece 32 is sleeved in the distal end of the locking hole 21, each rotating locking piece 32 can simultaneously rotate on its own axis in the distal end of the corresponding locking hole 21, with its center line as a reference, and the adjustable range of its rotation offset angle a is ±15°, which can provide higher assembly flexibility for assemblers during assembly.

[0030] As another preferred scheme, by setting the range of mutual cooperation between each rotating locking piece 32 and the proximal side 212 of the corresponding locking hole to be no shorter than two-thirds of the length of the rotating locking piece 32, the reliability of the interference fit can be further improved; in addition, in this embodiment, when each rotating locking piece 32 and the proximal end of the corresponding locking hole 21 are in a state of mutual cooperation, the center line of each rotating locking piece 32 coincides with the center line of the locking hole 21. Based on this symmetrical structure, the assembler can slide the assembly box cover 2 and the box body more smoothly.

[0031] As another preferred solution, by providing a boss 310 at the top end of the hinge shaft 31, when each rotation locking piece 32 slides along the corresponding locking hole distal side 211 to the corresponding locking hole proximal side 212, the boss abuts against the upper plane of the locking hole proximal side 212. Based on this arrangement, when the box cover 2 and the box body are covered with each other, the box cover 2 can also be prevented from being separated vertically relative to the box body.

[0032] After the box cover 2 and the box body are locked with each other, in order to prevent the box cover 2 from sliding back relative to the box body and causing unlocking, in this embodiment, a fixed column 42 and a long-axis hole locking piece 41 slidably hinged to the fixed column 42 are provided on the side wall 11 of the box body, and a first locking position 117 and a second locking position 22 are provided on the edge of the upper box edge 12. The long-axis hole locking piece 41 slides along the fixed column 42 and engages with the first locking position 117 and the second locking position 22 to form a locking switch that can lock the upper box edge 12 and the box cover 2 with each other. The long-axis hole locking piece 41 resists sliding of the edge of the box cover 2, and the rotating locking piece 32 resists sliding of the locking hole 21, so that the box cover 2 can be prevented from sliding horizontally relative to the upper box edge 12, and the box cover 2 and the box body can be effectively firmly locked. Example

[0033] like Figure 6 As shown, on the basis of Example 1, the structure of the side wall 11 is optimized in this embodiment to further improve its load-bearing effect. Specifically, the side wall 11 includes an inner wall 111, an upper outer wall 113, and a lower outer wall 114. The elastic bending parts 5 of the inner wall 111, the upper outer wall 113, and the lower outer wall 114 are arranged at the corners of the box body. The inner wall 111 is fixedly engaged with the lower plug-in block 1122 and the upper plug-in block 1121 corresponding to the lower plug-in hole 131 of the box bottom 13 and the upper plug-in hole 141 of the upper box edge 12. The handle part 6 arranged on the inner wall 111 passes through the through hole 110 of the upper outer wall 113. The upper outer wall 113 and the lower outer wall 114 are enclosed outside the inner wall 111. A pair of concave T-shaped upper buckling parts 115 are arranged on the lower edges of both sides of the upper outer wall 113, and a pair of convex upper buckling parts 115 are arranged on the upper edges of both sides of the lower outer wall 114. The T-shaped lower buckling portion 116 encloses the upper outer wall 113 and the lower outer wall 114 outside the inner wall 111, and makes the upper buckling portion 115 and the lower buckling portion buckle mutually. Through this arrangement, the load-bearing effect can be further improved; when the box body is used in a standing or lifting manner, and the inner space formed by the inner wall 111 is filled with heavier objects, and the inner wall 111 is slightly deformed along the elastic bending portion 5, the upper outer wall 113 and the lower outer wall 114 can be clamped by the upper buckling portion 115 and the lower buckling portion 116, and the elastic bending portion 5 of the lower outer wall 114 and the elastic bending portion 5 of the inner wall 111 together constitute a double-layer elastic bending portion 5 structure, which can further improve the weighing capacity of this part.

[0034] 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.
