DETAILED DESCRIPTION

[0026] The application will be further described in detail below with reference to the accompanying drawings.

[0027] As Figures 1-2 shown, a box body assembling device for installing a box cover on a box body, the box body assembling device comprising an abutting portion 1 for pressing the box cover and the box body in a first direction and an elastic portion 2 provided on one side of the abutting portion 1, the abutting portion 1 having a first abutting surface 11 facing the box cover, and the elastic portion 2 having a second abutting surface 21 capable of being elastically moved relative to the first abutting surface 11 in the first direction, in particular, the elastic portion 2 is provided with an elastic member 23, in the normal state of the elastic member 23, the elastic portion 2 protrudes from the abutting portion 1, as Figure 1 shown, the second abutting surface 21 is provided below the first abutting surface 11, forming a difference in height, and further forming a stepped structure similar to a step; when the abutting portion 1 is stressed, the elastic member 23 will be compressed, the distance between the second abutting surface 21 and the first abutting surface 11 will be reduced, and even a state where the second abutting surface 21 is flush with or above the first abutting surface 11 will be formed.

[0028] The second abutting surface 21 capable of being elastically moved relative to the first abutting surface 11 in the first direction specifically refers to the second abutting surface 21 changing from the state of being below the first abutting surface 11 to the state of being close to, flush with or above the first abutting surface 11.

[0029] The first direction refers to the direction of movement for installing the box cover on the box body, specifically Figure 1 the up-down direction in .

[0030] The elastic portion 2 can be elastically deformed according to the size difference between the box cover and the box body, making the assembling process more smooth, and avoiding the problem of poor assembly caused by improper force control in the traditional mechanical pressing method. The stepped structure can guide the box cover to accurately enter the box body, improving the accuracy and reliability of the assembly.

[0031] The elastic part 2 can play a buffering and supporting role, effectively preventing the deformation or damage of the box cover and the box body, and ensuring the assembly precision. The assembly force is reduced, and the box body is protected. The elastic part 2 can absorb part of the assembly force, reduce the impact on the box cover and the box body, effectively protect the box body, and avoid the problem of box body damage caused by excessive compression.

[0032] When the abutting part 1 is stressed, the elastic piece 23 is compressed, the second abutting surface 21 gradually moves upward, and the installation is completed. At this time, the abutting part 1 tightly presses the box cover and the box body together, and the assembly is completed.

[0033] The assembly process is as follows: the box cover is grabbed using the abutting part 1, the box cover is in contact with the first abutting surface 11; the box body is placed on the box cover, the box body is in contact with the second abutting surface 21; pressure is applied, the abutting part 1 moves downward, the elastic piece 23 is compressed, the second abutting surface 21 gradually moves upward, and the assembly is completed.

[0034] The preferred elastic piece 23 can be selected from springs, rubber, silicone, etc., and the appropriate material can be selected according to actual needs.

[0035] It is worth noting that during installation, since the elastic part 2 is arranged on one side of the abutting part 1, the stress on both sides of the first abutting surface 11 is necessarily uneven, and thus the side of the box cover on the first abutting surface 11 away from the elastic part 2 will first achieve a state with the box body, and the other side of the box cover will achieve cooperation with the box body during the gradual upward movement of the second abutting surface 21, which can realize the compression of the two sides of the box cover in a sequential order.

[0036] The box body is provided with a containing space extending to the upper end face of the box body to form a mounting port, and the box cover is mounted into the mounting port. In one preferred embodiment, the mounting port is a certain distance away from one side of the box body, i.e., there is still a circle of outer edge around the mounting port on the upper end face of the box body. The first abutting surface 11 abuts against the box cover, the stepped structure clamps one end of the box cover, and the second abutting surface 21 abuts against the upper end face of the box body, specifically, the second abutting surface 21 abuts against the outer edge. When the abutting part 1 is stressed, the elastic piece 23 is compressed, the second abutting surface 21 gradually moves upward, and the installation is completed. At this time, the first abutting surface 11 and the second abutting surface 21 are both above the box cover.

[0037] In another preferred embodiment, the elastic part 2 is arranged on one side of the box body. During installation, the box body is placed on the bottom plate, and the elastic part 2 also abuts against the bottom plate. When the abutting part 1 is stressed, the elastic piece 23 is compressed, the second abutting surface 21 gradually moves upward, and the installation is completed. At this time, the first abutting surface 11 is above the box cover, the second abutting surface 21 is below the box cover, and the stepped structure clamps the box body.

[0038] Further, the elastic part 2 comprises a limiting structure 22, an elastic member 23 and a contact structure 24, the elastic member 23 is elastically deformed along the first direction, the limiting structure 22 and the contact structure 24 are respectively connected to two sides of the elastic member 23, the limiting structure 22 is relatively fixed with the abutting part 1, and the second abutting surface 21 is arranged on the contact structure. The limiting structure 22 comprises a horizontal plate 221 and a vertical plate 222 which are perpendicular to each other, the horizontal plate 221 and the vertical plate 222 are connected, one end of the elastic member 23 is connected to the horizontal plate 221, the other end of the elastic member 23 abuts against the contact structure 24, and the vertical plate 222 is arranged on the side of the elastic member 23 which is away from the abutting part 1.

[0039] The limiting structure 22 limits the deformation range of the elastic member 23, ensures that the elastic member 23 will not be excessively deformed during assembly, and thus ensures the assembly precision. The combination of the horizontal plate 221 and the vertical plate 222 enables the elastic member 23 to be stable while being deformed along the first direction, avoids the torsional deformation of the elastic member 23, and further improves the assembly precision. The vertical plate 222 is arranged on the side of the elastic member 23 which is away from the abutting part 1, effectively prevents the elastic member 23 from falling off during deformation, and enhances the safety of the device.

[0040] It is worth noting that the contact structure 24 is block-shaped, the contact area of the contact structure 24 is larger when being block-shaped, the force and pressure can be more uniformly transmitted, and the local deformation or sliding of the elastic member 23 during force application is effectively prevented, thereby improving the assembly precision.

[0041] The contact structure 24 is block-shaped and has stronger load-bearing capacity, can withstand greater assembly force, and makes the assembly process more stable and reliable; the contact area of the contact structure 24 is larger when being block-shaped, stress concentration can be reduced, the block-shaped structure can more effectively disperse stress, reduce stress concentration, improve structural strength and service life. Moreover, the block-shaped contact structure 24 is easy to process, easy to manufacture, has simpler manufacturing process and lower cost.

[0042] Further, the abutting part 1 comprises a first end portion 12 and a second end portion 13, the first end portion 12 and the second end portion 13 are connected, the second end portion 13 is bent towards the horizontal plate 221, and the first abutting surface 11 is arranged on the first end portion 12; a hole is formed in the second end portion 13, the contact structure 24 penetrates through the hole, and the elastic member 23 is arranged between the second end portion 13 and the horizontal plate 221.

[0043] In a preferred embodiment, the hole extends to one side of the second end portion 13, the vertical plate 222 abuts against the second end portion 13, the second end portion 13 and the vertical plate 222 jointly form an expansion channel, and the contact structure 24 moves along the expansion channel.

[0044] The abutting part 1 is stably supported by the telescopic channel formed by the second end part 13 and the vertical plate 222, preventing the abutting structure 24 from loosening or falling off during force application, thereby enhancing the stability of the device.

[0045] The telescopic channel effectively prevents the abutting structure 24 from accidentally falling off during assembly, thereby improving the safety of the device.

[0046] Further, the second end part 13 is arranged between the first end part 12 and the vertical plate 222, and the first end part 12, the second end part 13, and the vertical plate 222 form a groove, and the abutting structure 24 is arranged in the groove.

[0047] The groove structure forms a closed support space for the abutting structure 24, preventing the abutting structure 24 from deviating or falling off during force application, thereby improving the stability and reliability of the abutting structure 24. The addition of the vertical plate 222 provides additional support for the groove, further enhancing the stability of the abutting structure 24.

[0048] The groove structure can accurately position the abutting structure 24, ensuring its accurate relative position with the box body components, thereby improving assembly accuracy. The abutting structure 24 moves within the groove, avoiding interference with other components and reducing errors during assembly.

[0049] The groove structure can guide the installation of the abutting structure 24, simplifying the assembly operation and reducing the assembly difficulty. The installation position of the abutting structure 24 is fixed within the groove, eliminating the need for additional positioning and improving assembly efficiency.

[0050] The groove structure can absorb external impact forces, protecting the abutting structure 24 from direct impact, thereby enhancing the impact resistance of the device. The groove structure tightly connects the first end part 12, the second end part 13, and the vertical plate 222 together, forming a monolithic structure and enhancing the overall structural strength of the device.

[0051] Preferably, a plurality of suction cups 14 are arranged on the first abutting surface 11, and the suction cups 14 abut the box cover. The suction cups 14 achieve suction of the box cover.

[0052] Further, a protrusion 15 is arranged on the abutting part 1, protruding from the first abutting surface 11. During the pressing process, the protrusion 15 first contacts the box cover or the box body. The protrusion 15 supports one end of the box cover, unlike a flat surface that can only exert downward pressure. During the inclined pressing process, the protrusion 15 generates a component force along the inclined installation direction, effectively concentrating the pressing force on the other end of the box cover, thereby achieving tight pressing of the box cover.

[0053] Further, the protrusion 15 is matched with the recess or side edge on the box cover, specifically, the protrusion 15 is arranged on the side of the first abutting surface 11 close to the elastic part 2, and the box cover is provided with a recess, and the protrusion 15 is matched with the recess; the protrusion 15 and the first abutting surface 11 form a step to clasp one side of the box cover, so that the protrusion 15 and the box cover are more stably matched, the protrusion 15 and the recess or the side edge are matched, a greater compression force can be realized with a smaller force, and the compression efficiency is improved.
