Description

Technical Field

[0001] This utility model relates to the field of rivet gun technology, and more specifically, to a rivet gun with good fixation. Background Technology

[0002] Electrical cabinets are industrial equipment used for the centralized installation, protection and management of electrical equipment. Their core functions include power distribution, circuit protection and automatic control. During the processing, production and assembly of electrical cabinets, rivets are used for locking and fixing. As a highly efficient riveting tool, rivet guns are widely used in the connection of metal components in various industries.

[0003] Chinese patent CN213134925U discloses a rivet gun with good fixing performance, including a rivet gun base, a handle, an anti-slip plate, a trigger, and a switch. The rivet gun base is located below the handle and is fixedly connected to the handle. An anti-slip plate is located in the middle of the handle. However, in actual use, the following defects still exist. The rivet gun is fixed by the base, but when it needs to be moved, the rivet head is prone to tilting with the cabinet surface when it is in contact with the cabinet surface. This causes the rivet to tilt during the riveting process, resulting in the riveting offset and affecting the fixing effect. Therefore, a rivet gun with good fixing performance is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rivet gun with good fixation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rivet gun with good stability, comprising a pneumatic rivet gun body and a rivet head located at one end of the pneumatic rivet gun body, wherein a fixing mechanism is sleeved on one end of the pneumatic rivet gun body near the rivet head, and the fixing mechanism can be conveniently installed on one end of the rivet head of the pneumatic rivet gun body, and the fixing mechanism can improve the stability of one end of the rivet head when the rivet head is in use; The fixing mechanism includes a support ring fitted around one end of the pneumatic rivet gun body. Two limiting rings are fixedly fitted around the outside of the support ring, and a first rotating ring is arranged between the two limiting rings. A spiral ring is fixedly connected to the inner cavity of the first rotating ring. A stabilizing ring is arranged at the end of the support ring near the rivet head. A plug rod is fixedly connected to one side of the stabilizing ring. The limiting ring limits the first rotating ring, and the first rotating ring drives the spiral ring to rotate. The plug rod can be controlled to drive the stabilizing ring to move horizontally. After the position of the support ring is fixed, the position of the stabilizing ring can be adjusted so that one side wall of the stabilizing ring fits against one end wall of the rivet head. This allows the rivet head to fit horizontally against the wall of the electrical cabinet during rivet pulling, avoiding tilting and thus improving the fixing effect of the rivet. A second rotating ring is fitted onto the end of the support ring furthest from the stabilizing ring. A movable ring is inserted into one end of the second rotating ring, and a slider is fixedly connected to one end of the movable ring. Multiple pressing blocks are arranged inside the movable ring, and a fixed plate is fixedly connected to one end of each pressing block. A sliding hole is opened on the surface of the fixed plate. Rotating the second rotating ring causes it to move towards the first rotating ring, which in turn moves the movable ring towards the first rotating ring. This, in turn, drives the pressing blocks to move through the fixed plate and the slider. The inner wall of the pressing block, through its cooperation with the inclined surface of the inner cavity of the support ring, allows the inner wall of the pressing block to press against the surface of the column at one end of the pneumatic rivet gun body, facilitating the installation and fixing of the support ring. As the pressing block moves horizontally, it also moves towards the axis, thus pressing the pressing block. The cooperation of the slider and the sliding hole improves the stability of the movement of the pressing block and the fixed plate.

[0006] Preferably, one end of the insertion rod penetrates the wall of the support ring, and a threaded groove is formed on the outer surface of the insertion rod. The outer surface of the insertion rod meshes with the inner wall of the spiral ring. The movement of the insertion rod is controlled by the rotation of the spiral ring, which can adjust the movement position of the stabilizing ring and facilitate adjustment and use.

[0007] Preferably, a limiting ring groove is formed on one side of the first rotating ring, and a plurality of first limiting rivets are formed on the side of one of the limiting rings. One end of the first limiting rivet extends to the middle of the limiting ring groove. By inserting one end of the first limiting rivet into the middle of the limiting ring groove, the position of the first rotating ring can be limited without affecting the normal rotation of the first rotating ring.

[0008] Preferably, the inner wall of the support ring away from the stabilizing ring is configured as a trumpet-shaped structure, and an arc-shaped inclined surface is provided on the outer side of one end of the extrusion block. One end of the extrusion block is located in the middle of the support ring and corresponds to the inclined surface of the inner cavity of the support ring. When the extrusion block moves horizontally, it generates a force that moves towards the axis, thereby facilitating the extrusion of one end of the outer surface of the pneumatic rivet gun body and facilitating the fixation of the position of the support ring.

[0009] Preferably, a second limiting rivet is inserted around the second rotating ring, and an annular groove is formed on the outer side of one end of the moving ring. One end of the second limiting rivet extends to the middle of the annular groove. Through the cooperation of the second limiting rivet and the annular groove, the moving ring and the second rotating ring can be connected, and the horizontal movement of the moving ring is not affected when the second rotating ring rotates.

[0010] Preferably, the extrusion block and the insertion rod are offset from each other, the inner wall of the extrusion block is set as an arc-shaped structure, and the inner wall of the extrusion block is in contact with the outer surface of one end of the pneumatic rivet gun body. By extruding the wall of one end of the pneumatic rivet gun body by the extrusion block, the position of the support ring can be fixed.

[0011] Preferably, the slider has a "T" shaped cross-section, the slider passes through the middle of the sliding hole, and the fixing plate is located on the side of the moving ring away from the second rotating ring. By sliding the slider inside the sliding hole, the stability of the extrusion block movement can be improved when the extrusion block moves horizontally and vertically.

[0012] Preferably, the second rotating ring is threadedly connected to the outer surface of the support ring, and one side wall of the stabilizing ring is on the same horizontal plane as one end wall of the rivet head. By rotating the second rotating ring while moving horizontally, the moving ring can be driven to control the movement of the extrusion block in sequence, which facilitates the installation and fixing of the support ring.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model firstly uses a stabilizing ring to ensure that the rivet head is perpendicular to the cabinet panel when one end of the rivet head is in contact with the cabinet body. This helps to prevent tilting and misalignment during rivet installation, improves the strength and quality of the rivet fixation, and enhances the rivet quality. Furthermore, by rotating the first rotating ring, the position of the stabilizing ring can be horizontally adjusted according to the installation position of the support ring. This allows for the combination and connection of various specifications and sizes of pneumatic rivet gun bodies. 2. This utility model also controls the moving ring to drive the extrusion block to move sequentially by rotating the second rotating ring to extrude the wall of the pneumatic rivet gun body. This makes it easy to install and fix the position of the support ring. The moving ring and the second rotating ring can be easily connected by the cooperation of the second limiting rivet and the annular groove. The moving ring can be connected to the extrusion block by sliding the slider inside the sliding hole without affecting the driving effect of the extrusion block. In summary, through the interaction of the above-mentioned multiple functions, the rivet head can be made perpendicular to the cabinet panel, thereby avoiding tilting and misalignment during riveting, improving the strength and quality after riveting and fixing, and improving the quality of riveting.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-4 The rivet gun shown includes a pneumatic rivet gun body 1 and a rivet head 2 located at one end of the pneumatic rivet gun body 1. A fixing mechanism is provided at one end of the pneumatic rivet gun body 1 near the rivet head 2. The fixing mechanism can be conveniently installed at one end of the rivet head 2 of the pneumatic rivet gun body 1, and the fixing mechanism can improve the stability of one end of the rivet head 2 when it is in use. The fixing mechanism includes a support ring 3 fitted onto one end of the pneumatic rivet gun body 1. Two limiting rings 4 are fixedly fitted on the outside of the support ring 3. A first rotating ring 5 is set between the two limiting rings 4. A spiral ring 6 is fixedly connected to the inner cavity of the first rotating ring 5. A stabilizing ring 9 is set on one end of the support ring 3 near the rivet head 2. A plug rod 8 is fixedly connected to one side of the stabilizing ring 9. The first rotating ring 5 is limited by the limiting rings 4, and the spiral ring 6 is rotated by the first rotating ring 5. The plug rod 8 can be controlled to drive the stabilizing ring 9 to move horizontally. The position of the stabilizing ring 9 can be adjusted after the position of the support ring 3 is fixed, so that one side wall of the stabilizing ring 9 fits against one end wall of the rivet head 2. When the rivet head 2 is riveting, it can fit horizontally against the wall of the electrical cabinet, avoiding tilting, thereby improving the fixing effect of the rivet. A second rotating ring 10 is fitted onto the end of the support ring 3 away from the stabilizing ring 9. A moving ring 12 is inserted into one end of the second rotating ring 10. A slider 17 is fixedly connected to one end of the moving ring 12. Multiple pressing blocks 14 are arranged inside the moving ring 12. A fixing plate 15 is fixedly connected to one end of the pressing block 14. A sliding hole 16 is opened on the surface of the fixing plate 15. Rotating the second rotating ring 10 causes it to move towards the first rotating ring 5, which in turn drives the moving ring 12 to move towards the first rotating ring 5. Then, through the fixing plate 15 and the slider 17, the pressing block 14 is moved. Through the cooperation between the inclined surface of the inner cavity of one end of the support ring 3 and the pressing block 14, the inner wall of the pressing block 14 can press the surface of the column at one end of the pneumatic rivet gun body 1, which facilitates the installation and fixing of the support ring 3. When the pressing block 14 moves horizontally, it will move towards the axis, thereby pressing the pressing block 14. Through the cooperation of the slider 17 and the sliding hole 16, the stability of the movement of the pressing block 14 and the fixing plate 15 is improved.

[0021] As attached Figure 1-4 As shown, one end of the insertion rod 8 penetrates the wall of the support ring 3. A threaded groove is formed on the outer surface of the insertion rod 8. The outer surface of the insertion rod 8 meshes with the inner ring wall of the spiral ring 6. A limiting ring groove is formed on one side of the first rotating ring 5. Multiple first limiting rivets 7 are formed on the side of one of the limiting rings 4. One end of the first limiting rivet 7 extends to the middle of the limiting ring groove. The movement of the insertion rod 8 is controlled by the rotation of the spiral ring 6, which can adjust the movement position of the stabilizing ring 9 for easy adjustment. By inserting one end of the first limiting rivet 7 into the middle of the limiting ring groove, the position of the first rotating ring 5 can be limited without affecting the normal rotation of the first rotating ring 5.

[0022] As attached Figure 1-4As shown, the inner wall of the support ring 3 away from the stabilizing ring 9 is set in a trumpet shape. One end of the pressing block 14 has an arc-shaped inclined surface. One end of the pressing block 14 is located in the middle of the support ring 3 and corresponds to the inclined surface of the inner cavity of the support ring 3. The second rotating ring 10 is inserted with second limiting rivets 11 around its perimeter. One end of the moving ring 12 has an annular groove 13. One end of the second limiting rivet 11 extends to the middle of the annular groove 13. The pressing block 14 and the insert rod 8 are offset from each other. The inner wall of the pressing block 14 is set in an arc shape. The inner wall of the pressing block 14 is in contact with the outer surface of one end of the pneumatic rivet gun body 1. The cross-sectional shape of the slider 17 is set in a "T" shape. The slider 17 passes through the middle of the sliding hole 16. The fixing plate 15 is set on the side of the moving ring 12 away from the second rotating ring 10. The second rotating ring 10 is threadedly connected to the outer surface of the support ring 3. The stabilizing ring 9 has one The side wall and one end wall of the rivet head 2 are on the same horizontal plane. When the pressing block 14 moves horizontally, it generates a force that moves towards the axis, which facilitates the pressing of one end of the outer surface of the pneumatic rivet gun body 1 and the fixing of the position of the support ring 3. Through the cooperation of the second limiting rivet 11 and the annular groove 13, the moving ring 12 can be connected to the second rotating ring 10. At the same time, when the second rotating ring 10 rotates, it does not affect the horizontal movement of the moving ring 12. By pressing the one end wall of the pneumatic rivet gun body 1 with the pressing block 14, the position of the support ring 3 can be fixed. By sliding the slider 17 inside the sliding hole 16, the stability of the pressing block 14 can be improved when the pressing block 14 moves horizontally and vertically. By rotating the second rotating ring 10 while moving horizontally, the moving ring 12 can be driven to control the movement of the pressing block 14 in sequence, which facilitates the installation and fixing of the position of the support ring 3.

[0023] It is worth noting that the inner wall of the threaded hole of the second rotating ring 10 and the threaded hole corresponding to the first limiting rivet 7 and the second limiting rivet 11 are provided with annular grooves in the axial direction. Nylon 66 damping rings with a Shore hardness of 85A are embedded in the grooves. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit of 15°-20° with the surfaces of the second rotating ring 10, the first limiting rivet 7, and the second limiting rivet 11. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread springback. Furthermore, the pneumatic rivet gun body 1 described in this application is a high-efficiency riveting tool powered by compressed air, mainly used for riveting operations in fields such as metal sheet manufacturing, automobile manufacturing, and aerospace. Its core function is to generate pulling force by driving a piston with air pressure to quickly complete the riveting process of the core-pulling rivet. This is existing technology and will not be elaborated further.

[0024] The working principle of this utility model is as follows: When in use, the support ring 3 is placed on the end of the pneumatic rivet gun body 1 near the rivet head 2, and then the second rotating ring 10 is rotated to drive the pressing block 14 to move into the support ring 3 in sequence, and the pressing block 14 applies pressure to the outer surface of one end of the pneumatic rivet gun body 1 to achieve the installation and fixation of the support ring 3. Then rotate the first rotating ring 5 to control the insertion rod 8 to move the stabilizing ring 9 so that one side wall of the stabilizing ring 9 is on the same horizontal plane as one end wall of the rivet head 2, thus completing the adjustment; When the pneumatic rivet gun body 1 is used for riveting, one end of the rivet head 2 and one side wall of the stabilizing ring 9 can be attached to the electrical cabinet wall, so that one end of the rivet is inserted into the interior of one end of the rivet head 2. During riveting, the rivet head 2 is always perpendicular to the electrical cabinet wall, which improves the quality of the riveting fixation effect.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
