A box with detachable corners

Abstract

This utility model discloses a box with detachable corner protectors, including a box body and corner protectors. The corner protectors are detachably installed at the corners of the box body. The inner shape of the corner protector matches the corner shape of the box body and is detachably connected via a connector. A reinforcing wing extends from the outer side of the corner protector and is attached to the side wall of the box body. The reinforcing wing has through holes for threading straps or ropes. The corner protector is detachably installed to the box body via a bolt and threaded sleeve connector. When the corner protector is damaged due to collision or wear, the entire box body does not need to be replaced; only the bolts need to be removed to replace the corner protector individually. The reinforcing wing extending from the outer side of the corner protector, with through holes for threading straps or ropes, helps to secure the box body during transport, solving the problem of traditional corner protectors only providing impact protection. Simultaneously, the reinforcing wing, attached to the side wall of the box body, combined with the reinforcing plate embedded inside the corner protector, further enhances the structural strength of the box corner.

Description

Technical Field

[0001] This utility model relates to the technical field of box protection devices, specifically to a box with detachable corner protectors. Background Technology

[0002] In industrial transportation and precision instrument storage, instrument cases and precision equipment cases need to withstand the impact of handling and environmental corrosion over long periods. Their corners, as areas of concentrated stress, require extremely high levels of protective structure. The corner protectors of these cases must possess excellent impact resistance to prevent damage to valuable internal equipment from external forces, while also being adaptable to scenarios involving repeated handling and long-term use.

[0003] In existing technologies, corner protectors for transport cases, instrument cases, etc., mostly adopt a fixed design, permanently installed to the corners of the case by adhesive or welding. This design has obvious drawbacks: First, corner protectors are prone to damage due to collisions and wear during long-term use, and the fixed structure makes it difficult to replace them individually after damage, often requiring the replacement of the entire case; Second, corner protectors have a limited function, only providing basic impact protection, lacking structures adapted for binding straps and ropes, failing to assist in securing the case during handling, and lacking additional reinforcement structures to improve protective performance, making it difficult to meet the high requirements of transporting precision equipment.

The positioning protrusion and the positioning groove cooperate with each other to achieve rapid positioning.

[0012] (III) Technical Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. The corner protectors are detachably installed on the enclosure via a bolt and threaded sleeve connector. When the corner protectors are damaged due to collision or wear, the entire enclosure does not need to be replaced; only the bolts need to be removed to replace the corner protectors individually.

[0015] 2. The outer side of the corner protector extends to form a reinforcing wing, and the through holes on it can be used to thread binding straps or ropes to help fix the box during transportation, solving the problem that traditional corner protectors can only prevent collisions. At the same time, the reinforcing wing is attached to the side wall of the box, and together with the reinforcing plate embedded inside the corner protector, it further enhances the structural strength of the corner of the box.

[0016] 3. The raised sealing strip on the contact surface between the corner protector and the cabinet can effectively block dust, and the positioning protrusions at the corners of the cabinet cooperate with the positioning grooves on the inside of the corner protector to achieve quick installation and positioning of the corner protector.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Combined with appendix Figure 1 To be continued Figure 6 A box with detachable corner protectors includes a box body 1 and corner protectors 2. The corner protectors 2 are detachably installed at the corners of the box body 1. The inner shape of the corner protector 2 matches the corner shape of the box body 1 and is detachably connected by a connector 3. The connector 3 is a combination of a bolt 31 and a threaded sleeve 33. The corner of the box body 1 is provided with a mounting hole 4 in which the threaded sleeve 33 is embedded. The corner protector 2 is provided with a corresponding connecting hole 5. The bolt 31 passes through the connecting hole 5 and the mounting hole 4 and is fastened to the threaded sleeve 33. The outer side of the corner protector 2 extends to form a reinforcing wing 10. The reinforcing wing 10 is attached to the side wall of the box body 1. The reinforcing wing 10 is provided with a through hole 11 for threading a binding strap or rope.

[0028] The connecting hole 5 of the corner protector 2 is a countersunk hole, and the head of the bolt 31 is recessed into the countersunk hole. A raised sealing strip 9 is fixed on the contact surface between the corner protector 2 and the housing 1 for waterproofing and dustproofing. A reinforcing plate 12 is embedded inside the corner protector 2. The reinforcing plate 12 is a metal plate or an engineering plastic plate.

[0029] A positioning protrusion 13 is provided at the corner of the box body 1, and a positioning groove 14 is provided at the corresponding position on the inner side of the corner protector 2. The positioning protrusion 13 and the positioning groove 14 cooperate with each other to achieve rapid positioning.

[0030] The working principle of this utility model is as follows: Before installing the corner protector 2, align and engage the positioning groove 14 on the inner side of the corner protector 2 with the positioning protrusion 13 at the corner of the box 1. Through the cooperation between the positioning protrusion 13 and the positioning groove 14, the installation position of the corner protector 2 on the box 1 is quickly determined. After positioning is completed, pass the bolt 31 through the connecting hole 5 on the corner protector 2, and then insert it into the threaded sleeve 33 at the corner of the box 1. Rotate the bolt 31 to make it securely connected with the threaded sleeve 33. At this time, the corner protector 2 is stably fixed in the corner of the box 1. Since the connecting hole 5 is a countersunk hole, the head of the bolt 31 can be recessed into the countersunk hole, avoiding the bolt head from protruding outwards and affecting use or causing bumps. In daily use, the reinforcing plate 12 embedded inside the corner protector 2 and the reinforcing wing 10 extending outwards together enhance the impact resistance of the corner of the box 1, reducing damage to the box from handling impacts. The raised sealing strip 9 on the contact surface between the corner protector 2 and the box 1 fits tightly to block dust. When it is necessary to secure the box for handling, straps or ropes can be passed through the through holes 11 on the reinforcing wing 10 to limit the straps or ropes, thus achieving stable binding and fixing of the box. If the corner protector 2 is damaged, simply rotate the bolt 31 in the opposite direction to separate the bolt 31 from the threaded sleeve 33, remove the bolt 31, and then remove the damaged corner protector 2. After replacing with a new corner protector, repeat the positioning and fixing steps to complete the maintenance.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
