Description

Technical Field

[0001] The utility model provides a wear-resistant copper shell, belonging to the technical field of copper shell protection. Background Art

[0002] Copper is a good electromagnetic shielding material that can effectively block the propagation of electromagnetic waves. Therefore, copper shells are often used in electronic equipment, communication equipment and other fields to shield electromagnetic interference and protect the electronic components inside the equipment from external interference; at the same time, a dense oxide layer can be formed on the surface of the copper shell, which can effectively prevent the copper itself from being further oxidized, thereby playing a certain anti-corrosion role and protecting the internal objects from corrosion. Therefore, the application field of copper shells is very wide, and it can play a good role in protection and corrosion prevention.

[0003] To facilitate installation and disassembly, many copper shells are composed of two half shells that fit together. The object to be protected is placed in the two half shells, and then the two half shells are fastened together by fasteners such as bolts. The wear resistance of copper shells is average. Especially in scenarios where copper shells need to be frequently disassembled and assembled, fasteners with higher hardness, such as bolts, rub repeatedly against the outer surface of the copper shell, which can easily cause wear or scratches on the copper surface. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when the copper protective shell is repeatedly disassembled and installed, fasteners with relatively high hardness rub against the surface of the copper shell, which easily causes wear or scratches on the copper shell.

[0005] In order to solve the above problems, the utility model proposes the following technical solutions: a wear-resistant copper shell, comprising a fastening box, in which a bidirectional screw is rotatably arranged; two corresponding movable plates are threadedly connected to the bidirectional screw; one side of the fastening box is provided with two upper and lower corresponding support plates, and the two support plates are respectively fixedly connected to the two movable plates, and the inner sides of the two support plates are respectively fixedly connected with a copper upper shell and a copper lower shell, and the upper shell and the lower shell are engaged with each other; a pipeline is arranged between the upper shell and the lower shell; arc-shaped pressure plates are arranged in both the upper shell and the lower shell, and the pressure plates are pressed on the pipeline.

[0006] As an improvement, a limiting groove is provided on one side of the fastening box, a limiting rod fixedly connected to the movable plate is arranged in the limiting groove, and the limiting rod is fixedly connected to the supporting plate.

[0007] As an improvement, a slide groove is provided in both the upper shell and the lower shell, and a slide rod is slidably arranged in the slide groove; one end of the slide rod is fixedly connected to the pressure plate, and a spring is sleeved on the slide rod.

[0008] As an improvement, a limit block fixedly connected to the sliding rod is slidably arranged in the sliding groove.

[0009] As an improvement, a card slot is provided in the upper shell, and a card block inserted into the card slot is fixedly connected to the lower shell.

[0010] As an improvement, sealing rings are provided at the positions where the upper shell, the lower shell and the pipeline meet.

[0011] Beneficial effects of the utility model:

[0012] A bidirectional screw is rotatably arranged in the fastening box, and two corresponding moving plates are threadedly connected to the bidirectional screw; by arranging the bidirectional screw, the movement of the moving plate is used to drive the upper shell and the lower shell to be spliced ​​or separated, and the disassembly and assembly can be completed quickly. At the same time, the fastening structure does not directly contact the surface of the copper shell, reducing the wear and scratches on the outer surface of the copper shell. Arc-shaped pressure plates are arranged in both the upper shell and the lower shell, and the pressure plates are pressed on the pipe, which can increase the stability of the connection between the protected pipe and the shell.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-4As shown: the utility model provides a wear-resistant copper shell: it includes a fastening box 1, in which a bidirectional screw 8 is rotatably arranged; two corresponding movable plates 9 are threadedly connected to the bidirectional screw 8; one side of the fastening box 1 is provided with two upper and lower corresponding support plates 4, and the two support plates 4 are respectively fixedly connected to the two movable plates 9, and the inner sides of the two support plates 4 are respectively fixedly connected with a copper upper shell 5 and a copper lower shell 6, and the upper shell 5 and the lower shell 6 are engaged with each other; a pipe 7 is arranged between the upper shell 5 and the lower shell 6; arc-shaped pressing plates 10 are arranged in the upper shell 5 and the lower shell 6, and the pressing plates 10 are pressed on the pipe 7.

[0020] By setting a bidirectional screw 8 and utilizing the movement of the movable plate 9 to drive the upper shell 5 and the lower shell 6 to be spliced ​​or separated, disassembly and assembly can be completed quickly. Therefore, the fastening structure does not directly contact the surface of the copper shell, reducing the wear and scratches on the outer surface of the copper shell during repeated disassembly and assembly.

[0021] A limiting groove 2 is provided on one side of the fastening box 1 , and a limiting rod 3 fixedly connected to the moving plate 9 is arranged in the limiting groove 2 , and the limiting rod 3 is fixedly connected to the supporting plate 4 .

[0022] The limiting groove 2 and the limiting rod 3 can limit the rotation of the movable plate 9 , thereby converting the rotation of the bidirectional screw 8 into the movement of the movable plate 9 and transmitting it to the supporting plate 4 through the limiting rod 3 .

[0023] A slide groove 15 is provided in both the upper shell 5 and the lower shell 6, and a slide rod 13 is slidably arranged in the slide groove 15; one end of the slide rod 13 is fixedly connected to the pressure plate 10, and a spring 16 is sleeved on the slide rod 13. A limit block 14 fixedly connected to the slide rod 13 is slidably arranged in the slide groove 15.

[0024] The provision of the spring 16 can provide pressure for the pressure plate 10 to clamp the pipe 7, while the provision of the limit block 14 can prevent the pressure plate 10 from being separated from the housing.

[0025] A card slot 11 is provided in the upper shell 5, and a card block 12 inserted into the card slot 11 is fixedly connected to the lower shell 6. A sealing ring is provided at the intersection of the upper shell 5, the lower shell 6 and the pipeline 7 to increase the sealing performance of the two shells after splicing.

[0026] Principle of the utility model

[0027] like Figure 1-2The figure shows the copper shell protecting the pipe 7 normally. The upper shell 5 and the lower shell 6 are stably spliced ​​together through the threaded connection of the bidirectional screw 8 and the movable plate 9. The two shells themselves do not have a fastening connection structure. Therefore, whether disassembling or splicing the two shells, the outer surface of the copper shell will not be repeatedly rubbed by high-strength bolts, etc., which can reduce the wear and scratches of the copper shell. When the copper shell needs to be disassembled, the bidirectional screw 8 is screwed, so that the two movable plates 9 drive the upper shell 5 and the lower shell 6 to move away from each other, and the disassembly of the copper shell can be completed. Figure 3 shown.

[0028] Similarly, when the upper and lower shells need to be spliced, the bidirectional screw 8 is screwed in the opposite direction, and the upper shell 5 and the lower shell 6 are brought closer to each other. First, the two pressure plates 10 contact the pipe 7. As the two shells continue to approach, the shells slide relative to the pressure plates 10, and the shells compress the springs 16, so that the springs 16 generate a rebound force on the pressure plates 10, thereby increasing the fastening effect of the pressure plates 10 on the pipe 7 and increasing the stability of the contact between the copper shell and the pipe 7. Figure 4 When the upper shell 5 and the lower shell 6 are completely spliced, the clamping block 12 is clamped into the clamping groove 11, and then the sealing ring is used to seal the intersection of the upper shell 5, the lower shell 6 and the pipeline 7.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
