[0003] However, manual installation requires specialized tools or skills, is time-consuming, and is easily affected by the precision of human operation; disassembly may damage the original structure, some connection methods are difficult to remove without damage, and residual marks or damage may affect the secondary use of sheet metal parts. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a firmly installed sheet metal part. Through the design of the plug connector and socket connector, it replaces the traditional complex connection methods such as welding and riveting. No professional tools or high-precision operation are required. Ordinary people can quickly complete the assembly by hand, reducing the time by more than 80%. The cooperation of its elastic limit hook, limit groove and limit block makes the positioning accurate, the operation simple and the installation secure. Moreover, the assembly can be intuitively judged by the clicking sound. Disassembly can be performed without damaging the structure. The limit relationship can be easily released, achieving 100% non-destructive disassembly, avoiding material damage and residual deformation. The parts can be reused, and the material utilization rate is increased by more than 80%. It effectively overcomes the shortcomings of traditional connection methods, such as being easily affected by the accuracy of human operation, difficult disassembly and easy damage to materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A securely installed sheet metal part includes an inner bracket. The outer side of the inner bracket is provided with a first side plate and a second side plate that are connected to it by insertion. The inner side of the first side plate is provided with at least two insertion connectors. A socket connector is provided on the side of the inner bracket at the position corresponding to the insertion connector. The insertion connector is used to cooperate with the socket connector to facilitate the installation of the first side plate and the inner bracket. The second side plate is installed at both ends of the first side plate and is connected to the inner bracket by the cooperation of the insertion connector and the socket connector.

[0007] The first side panel has a mounting part on one side, and the mounting part has at least two hooks. The mounting part is used to cooperate with the first side panel to install the configuration box, and the hooks are used to stably connect the configuration box.

[0008] The socket connector includes a sleeve, an elastic locking part at one end of the sleeve, a top pulling part at the other end of the sleeve, and a tension spring between the top pulling part and the elastic locking part. The sleeve is used to connect the first side plate to the inner bracket in conjunction with the socket connector. The elastic locking part is used to limit the socket connector in conjunction with the sleeve. The top pulling part is used to assist the elastic locking part in disengaging from the socket connector. The tension spring is used to pull the elastic locking part inward towards the sleeve when the top pulling part slides towards one end of the sleeve.

[0009] The sleeve is provided with at least two slots, and a pull groove is provided on one side of the slot. A limiting part is provided in the pull groove. The slot is used to cooperate with the elastic locking part to limit the socket connector, and the limiting part is used to cooperate with the pull groove to limit the top pulling part.

[0010] The elastic locking part has a first truncated cone at one end, and a first connecting part at one end of the first truncated cone. The first connecting part has at least two elastic limiting hooks on one side, and a pull hole connected to a tension spring on one side of the elastic limiting hook. The first truncated cone is used to be fixedly connected to the first side plate, and the first connecting part is used to be fixedly connected to the sleeve. The elastic limiting hook is used to cooperate with the slot of the sleeve to limit the positioning of the socket connector.

[0011] The top pulling part is provided with a second truncated cone at one end, and a second connecting part is provided at one end of the second truncated cone. At least two limiting pieces are provided on the outer side of the second connecting part, and at least two fixing blocks are provided at the top of the second connecting part. The second truncated cone is used to cooperate with the sleeve to drive the second connecting part to slide. The limiting piece is used to cooperate with the limiting part to limit the top pulling part. The fixing block is used to install the connecting tension spring.

[0012] The socket connector has a cavity for sliding connection between the sleeve and the socket connector. At least two limiting grooves are provided on the inner side wall of the cavity for sliding of the elastic limiting hook within the cavity. A limiting block is provided in the limiting groove for limiting the elastic limiting hook. At least one mounting plate is provided on the outer side of the socket connector for connecting to the inner bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the cooperation of the elastic limit hook and the limit block, quick manual installation is achieved. During installation, the elastic limit hook of the elastic locking part slides into the limit groove of the socket connector. When it passes the limit block, the elastic limit hook can rely on its own rigid deformation to spring back and lock, thereby completing the connection. This solves the problem that traditional sheet metal parts installation requires professional tools and skills. There is no need for complicated operations such as drilling positioning or anti-deformation control. Ordinary people can complete the installation by hand. This not only avoids the accuracy error of human operation, but also greatly shortens the installation time.

[0015] 2. When disassembling, push the top pull part. The fixing block of the top pull part will pull the tension spring, which will cause the elastic limit hook to retract and disengage from the limit block. At the same time, the limit piece and the limit part cooperate to ensure that the elastic limit hook is in the retracted state, thereby unlocking the mutual limiting state of the socket connector and the socket connector. This solves the problem that traditional sheet metal parts disassembly is prone to damage to the original structure. It avoids operations that may damage the material, such as welding, cutting, and heat separation of adhesives. This allows the disassembly process to achieve 100% non-destructive disassembly, greatly improving the utilization rate of sheet metal parts. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1-7As shown, this utility model relates to a securely installed sheet metal part, including an inner bracket 1. The outer side of the inner bracket 1 is respectively provided with a first side plate 2 and a second side plate 3 for socket connection. The inner side of the first side plate 2 is provided with at least two plug connectors 4. A socket connector 5 is provided on the side of the inner bracket 1 corresponding to the plug connectors 4. The plug connectors 4 are used to cooperate with the socket connectors 5 to facilitate the installation of the first side plate 2 and the inner bracket 1. The second side plate 3 is installed at both ends of the first side plate 2. The second side plate 3 is connected to the inner bracket 1 through the cooperation of the plug connectors 4 and the socket connectors 5. The cooperation of the plug connectors 4 and the socket connectors 5 enables the first side plate 2 and the second side plate 3 to be securely and reliably assembled with the inner bracket 1.

[0027] like Figure 1-2 As shown, a mounting part 20 is provided on one side of the first side panel 2. The mounting part 20 is provided with at least two hooks 200. The mounting part 20 is used to cooperate with the first side panel 2 to install the configuration box. The hooks 200 are used to stably connect the configuration box. The mounting part 20 is integrally formed with the first side panel 2. When two mounting parts 20 are arranged opposite each other on the first side panel 2, the hooks 200 include four sets, and they are opposite each other in pairs. The mounting part 20 can quickly install other auxiliary accessories, providing more positions for installing other parts on the base plate and providing more operating space for production.

[0028] like Figure 1-5 As shown in Figure 7, the socket connector 4 includes a sleeve 40, an elastic locking part 41 at one end of the sleeve 40, a top pulling part 42 at the other end of the sleeve 40, and a tension spring 43 between the top pulling part 42 and the elastic locking part 41. The sleeve 40 is used to connect the first side plate 2 to the inner bracket 1 in conjunction with the socket connector 5. The elastic locking part 41 is used to limit the socket connector 5 in conjunction with the sleeve 40. The top pulling part 42 is used to assist the elastic locking part 41 in disengaging from the socket connector 5. The tension spring 43 is used to assist the top pulling part 42 in retracting the elastic locking part 41 towards the inside of the sleeve during disassembly. The elastic locking part 41 is interference-fitted with the sleeve 40, and the top pulling part 42 is slidably connected to the sleeve 40. The socket connector 4 and the socket connector 5 cooperate with each other to enable convenient installation and disassembly of the first side plate 2 and the second side plate 3 with the inner bracket 1.

[0029] like Figure 3-5As shown in Figure 7, further, the sleeve 40 is provided with at least two slots 400, and a pull groove 401 is provided on one side of the slot 400. A limiting part 44 is provided in the pull groove 401. The slot 400 is used to cooperate with the elastic locking part 41 to limit the socket connector 5. The limiting part 44 is used to cooperate with the pull groove 401 to limit the top pulling part 42. One end of the elastic locking part 41 is provided with a first frustum 410. One end of the first frustum 410 is provided with a first connecting part 411. One side of the first connecting part 411 is provided with at least two elastic limiting hooks 412. One side of the elastic limiting hook 412 is provided with a pull hole 413 connected to the tension spring 43. The first frustum 410 is used to be fixedly connected to the first side plate 2. The first connecting part 411 is used to be interference-fitted with the sleeve 40. The elastic limiting hook 412 is used to cooperate with the slots 400 of the sleeve 40 to limit the socket connector 5.

[0030] like Figure 3-5 As shown in Figure 7, further, the two slots 400 correspond one-to-one with the two elastic limiting hooks 412 of the elastic locking part 41. After being tightened, the two elastic limiting hooks 412 have the elastic characteristic of automatically returning to the initial state. They are made of rigid materials such as iron sheets, copper sheets, and hard plastics. The initial state of the two elastic limiting hooks 412 is that one end of the limiting hook 4120 extends outward from the two slots 400 on the sleeve 40 and protrudes from the outer surface of the sleeve 40, so that the elastic limiting hooks 412 can cooperate with the socket connector 5 for limiting.

[0031] like Figure 3-5 As shown in Figure 7, further, a second frustum 420 is provided at one end of the top pull portion 42, and a second connecting portion 421 is provided at one end of the second frustum 420. At least two limiting pieces 422 are provided on the outer side of the second connecting portion 421, and at least two fixing blocks 423 are provided at the top end of the second connecting portion 421. The second frustum 420 is used to cooperate with the sleeve 40 to drive the second connecting portion 421 to slide. The limiting piece 422 is used to cooperate with the limiting portion 44 to limit the top pull portion 42. The fixing block 423 is used to install the connecting tension spring 43.

[0032] like Figure 3-5 As shown in Figure 7, a return spring 45 is further provided between the top pull part 42 and the sleeve 40. The return spring 45 is used to assist the top pull part 42 in resetting. When the top pull part 42 is assembled into the sleeve 40, one end of the tension spring 43 is first connected to the pull hole 413 on the side of the elastic limit hook 412, and the tension spring 43 is pulled out of the sleeve 40. The other end of the tension spring 43 is connected to the two fixing blocks 423 of the second connecting part 421. Then, the top pull part 42 is slidably pushed into the sleeve 40 to complete the assembly of the top pull part 42 and the sleeve 40.

[0033] like Figure 1-7As shown, the socket connector 5 has a cavity 50 inside, which is used to cooperate with the sleeve 40 and the plug connector 4 for sliding connection. At least two limiting grooves 51 are provided on the inner side wall of the cavity 50. The limiting grooves 51 are used to cooperate with the elastic limiting hook 412 to slide in the cavity 50. A limiting block 52 is provided in the limiting groove 51 to limit the elastic limiting hook 412. At least one mounting plate 53 is provided on one outer side of the socket connector 5. The mounting plate 53 is used to connect with the inner bracket 1. One side of the limiting block 52 is inclined to facilitate the elastic limiting hook 412 to be guided into the limiting groove 51.

[0034] The assembly principle is as follows: When the inner bracket 1 is assembled with the first side plate 2, the first side plate 2 is equipped with a four-prong connector 4, and a four-socket connector 5 is installed corresponding to the side position of the inner bracket 1. When the first side plate 2 is fastened to the inner bracket 1, the prong connector 4 is inserted into the corresponding socket connector 5. At this time, the elastic limiting hook 412 slides into the limiting groove 51 in the socket connector 5. When the elastic limiting hook 412 touches the limiting block 52 in the limiting groove 51, there will be a sense of resistance. At this time, the first side plate 2 is pushed further, so that the elastic limiting hook 412 is pushed into the limiting groove 51 along the inclined surface of the limiting block 52. The limiting hook 4120 passes the limiting block 52. At this time, the elastic limiting hook 412 is continuously squeezed and contracted. When the elastic limiting hook 412 passes the limiting block 52, the elastic limiting hook 4120 passes the limiting block 52. At time 2, the elastic limit hook 412 instantly returns to its initial state through its own rigidity and makes a clicking sound by rubbing against the limit block 52, indicating that the first side plate 2 has been assembled. At this time, the elastic limit hook 412 and the limit block 52 complete the limiting. At this time, the top pull part 42 and the return spring 45 are relaxed, and the bottom of the second frustum 420 of the top pull part 42 abuts against the bottom of the inner cavity 50 of the socket connector 5. Through the cooperation of these two (the elastic limit hook 412 and the limit block 52 complete the limiting, and the bottom of the second frustum 420 of the top pull part 42 abuts against the bottom of the inner cavity 50 of the socket connector 5), the first side plate 2 can neither slide inward nor detach from the inner bracket 1, thus completing the assembly of the first side plate 2. When disassembly is required, at this time, continue... Pushing the first side plate 2 forcefully towards one side of the inner bracket 1 causes the top pull part 42 to slide into the sleeve 40. The two fixing blocks 423 of the second connecting part 421 then pull the tension spring 43, causing the elastic limiting hook 412 to retract completely into the slot 400. The limiting piece 422 on the second connecting part 421 passes over the limiting part 44 inside the sleeve 40. At this time, the limiting part 44 limits the top pull part 42, keeping it in the pushed-in state. The return spring 45 is compressed, and the elastic limiting hook 412 is in the retracted state. This releases the mutual limiting relationship between the socket connector 4 and the receptacle connector 5, allowing the first side plate 2 to be easily removed from the inner bracket 1 without assistance. Other tools can be used to complete the disassembly. When it is necessary to reinstall the first side plate 2, simply pull the limiting part 44 outward along the pull groove 401 to release the limiting part 44 from the limiting piece 422. Under the automatic restoring force of the elastic limiting hook 412 and the return spring 45, the top pull part 42 slides out along the sleeve 40, and the elastic limiting hook 412 returns to its initial state. Push the limiting part 44 back into the pull groove 401. Repeat the above steps to complete the installation and disassembly of the first side plate 2. It should be noted that the installation and disassembly of the second side plate is the same as that of the first side plate. This design replaces the complex operations of welding and riveting, eliminates the need for drilling positioning or anti-deformation control, and can be assembled by hand by ordinary personnel, reducing the time by more than 80% and avoiding human operation precision errors, achieving 100% non-destructive disassembly.This design avoids material damage caused by welding, cutting, or heating with adhesives. After disassembly, the sockets and inserts remain free of residual deformation, and the components are reusable, increasing material utilization by over 80%.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
