[0002] Welding is a widely used metal connection processing technology. When welding is performed, the tools and materials needed to be carried are of various types, so a tool box is usually used to organize and store these items.

[0003] After a large amount of retrieval, a welding tool box is disclosed in CN205201474U, which includes an upper box body and a lower box body. The upper box body and the lower box body are hingedly connected through a hinge. The upper box body and the lower box body can rotate around the hinge joint and cover to form a storage cavity. The hinge includes a first hinge monomer provided on one side of the box body and a second hinge monomer provided on the other side of the box body. The first hinge monomer includes a first universal joint, and the second hinge monomer includes a second universal joint and a third universal joint. The first universal joint, the second universal joint, and the third universal joint are connected through a bolt and nut assembly. The first universal joint is located between the second universal joint and the third universal joint.

[0004] In the prior art, the first universal joint, the second universal joint, and the third universal joint are connected through a bolt and nut assembly during use. The bolt is used as a hinge pin. Since the bolt is fixed by a nut, it can prevent the bolt from falling off and causing the box body to malfunction. However, in actual use, the externally installed bolt and nut assembly itself still has the risk of falling off. At the same time, when the tool box is opened, if the force applied is too large, the bolt will be deformed under stress. In severe cases, the upper half and the lower half of the tool box will be damaged. Therefore, a high-assembly-precision electric welding machine plastic tool box is needed to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a high-assembly-precision electric welding machine plastic tool box, which has the advantages of ensuring structural stability and safety, reducing deformation and damage caused by excessive opening force, and solving the key problems of bolt and nut falling off and being easily damaged when opening.

[0033] Embodiment one

[0034] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the utility model provides an embodiment: a kind of high assembly precision electric welding machine plastic tool box, including bottom box 1 and top box 2, bottom box 1 and top box 2 are rotatably installed by hinge assembly 4, and the inside rear end of bottom box 1 and top box 2 is embedded with installation assembly 5 on both sides, and the upper and lower ends of hinge assembly 4 are fixedly installed in the installation assembly 5 of top box 2 and bottom box 1 respectively;Hinge assembly 4 includes upper blade 42 and lower blade 41, and upper blade 42 and lower blade 41 are elastically installed with positioning block 43 by return spring 44 on the side away from each other, and positioning block 43 is embedded in installation assembly 5.

[0035] Specifically, the hinge assembly 4 is connected by a rotating shaft and embedded in the mounting assembly 5 installed on the inner side of the rear end of the top box 2 and the bottom box 1.

The design of the return spring 44 allows the hinge assembly 4 to have a certain buffering effect when subjected to excessive opening force, thereby reducing deformation and damage caused by excessive force. The design of the mounting assembly 5 allows flexible installation through mounting screws 51, ensuring that the hinge assembly 4 can be stably fixed on the tool box. This precise assembly reduces the risk of deformation and damage caused by improper assembly. In summary, the high-assembly-precision plastic tool box for electric welding machines of the present application, through its unique design and structure, ensures the stability and safety of the structure, reduces deformation and damage caused by excessive opening force, and effectively solves the key problems of existing tool boxes, such as the easy falling off of bolts and nuts, and the easy damage during opening.

[0036] Example two

[0037] In order to avoid the tool box from being re-opened due to accidental touch after closing, as shown in Figure 1 and Figure 2 , in this embodiment, limit blocks 11 are arranged on both sides of the front end of the bottom box 1, and the limit blocks 11 are integrally formed with the bottom box 1 by injection molding process.

[0038] In the design, the limit blocks 11 are integrally formed with the bottom box 1 by injection molding process, which increases the overall strength and stability of the tool box and prevents deformation during use or transportation.

[0039] The limit blocks 11 provide precise docking points for the guide rails 21 of the top box 2, ensuring that the tool box can be accurately and smoothly locked when closed, avoiding misalignment or looseness.

[0040] Further, the top box 2 is provided with guide rails 21 on both sides of the front end, and the guide rails 21 are integrally formed with the top box 2 by injection molding process, and the guide rails 21 are clamped with the limit blocks 11 through the sliding lock 3.

[0041] In the design, the guide rails 21 are integrally formed with the top box 2, which not only enhances the firmness of the structure, but also reduces errors during assembly and improves assembly accuracy.

[0042] The design of the sliding lock 3 makes the opening and closing of the tool box more simple and fast, while ensuring the firmness of the tool box when closed.

[0043] Embodiment three

[0044] In order to improve the disassembly efficiency of the hinge assembly and improve its stability when in use, as shown in Figure 3 and Figure 4 In this embodiment, the mounting assembly 5 is frontally perforated and movably inserted with a mounting screw 51, and the mounting assembly 5 is provided with an insertion slot 52, and the rear end of the mounting screw 51 extends into the insertion slot 52.

[0045] The design of the mounting assembly 5 allows flexible installation and adjustment through the mounting screw 51, ensuring that the hinge assembly 4 can be firmly fixed on the tool box.

[0046] The design of the insertion slot 52 makes it easy to disassemble and reinstall when the hinge assembly 4 needs to be repaired or replaced, improving the maintainability of the tool box.

[0047] Further, the upper blade 42 and the lower blade 41 are rotatably connected by a rotating shaft, and the upper blade 42 and the lower blade 41 are both designed with stainless steel material, and the rear end of the bottom box 1 and the top box 2 at the connection of the upper blade 42 and the lower blade 41 are both provided with a groove.

[0048] The stainless steel material of the upper blade 42 and the lower blade 41 has excellent corrosion resistance, prolonging the service life of the tool box, and the rotating shaft connection design allows the upper blade 42 and the lower blade 41 to rotate smoothly, reducing the resistance and noise when opening and closing the tool box.

[0049] The grooves provided at the rear end of the bottom box 1 and the top box 2 provide additional installation space for the hinge assembly 4, ensuring the flatness and aesthetics of the tool box when closed.

[0050] Further, the reset spring 44 is designed with a tensile spring material, the two ends of the reset spring 44 are respectively elastically connected with the positioning block 43, the upper blade 42 or the lower blade 41, and the outer diameter of the reset spring 44 is smaller than the thickness of the positioning block 43.

[0051] The design of the reset spring 44 provides stable elastic support for the hinge assembly 4, ensuring the stability and reliability of the tool box during opening and closing.

[0052] The outer diameter of the reset spring 44 is smaller than the thickness of the positioning block 43, so that the hinge assembly 4 can maintain a compact structure during installation without occupying additional space.

[0053] Further, the positioning block 43 has a thickness matching that of the upper blade 42 and the lower blade 41, and a mounting screw hole 431 is formed in the front face of the positioning block 43.

[0054] In the design, the thickness of the positioning block 43 matches that of the upper blade 42 and the lower blade 41, thereby ensuring the accuracy and stability of the hinge assembly 4 during installation, and the upper blade 42 and the lower blade 41 can be slid into the insertion slot when the toolbox is closed.

[0055] The design of the mounting screw hole 431 enables the mounting screw 51 to firmly fix the positioning block 43 and the hinge assembly 4 on the mounting assembly 5, thereby improving the overall strength and durability of the toolbox.

[0056] During use, the front end of the top box 2 is held, the sliding lock 3 is slid, and the top box 2 is gently lifted upward. As the top box 2 is opened, the hinge assembly 4 starts to work. The upper blade 42 and the lower blade 41 are smoothly rotated through the rotating shaft. Due to the extrusion of the top box 2 and the rear end of the bottom box 1, the upper blade 42 and the lower blade 41 will slide out of the insertion slot 52 in the mounting assembly 5, so that the top box 2 can be opened to the maximum extent.

[0057] When the toolbox is closed, the top box 2 is rotated along the hinge assembly 4 and gently pressed downward, so that the guide rail 21 is aligned with the sliding block. After the top box 2 and the bottom box 1 are closed, the sliding lock 3 is manually slid, and the sliding lock 3 is slid to the connection between the guide rail 21 and the sliding block, thereby locking the closed state of the top box 2 and the bottom box 1. At the same time, the upper blade 42 and the lower blade 41 of the hinge assembly 4 are slid into the insertion slot 52 of the mounting assembly 5 again under the action of the reset spring 44, thereby providing additional stable support for the connection between the top box 2 and the bottom box 1.

[0058] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
