Description

Technical Field

[0001] This application relates to the field of riveting equipment technology, specifically to a lever structure and a rivet gun. Background Technology

[0002] Rivet guns are used for fastening and riveting various metal sheets, pipes, and other materials in the manufacturing industry. They are widely used in riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration.

[0003] Currently, some AC rivet guns on the market use a lever plate structure that is fixed by a pin and a cam-shaped lever plate. However, the lever plate structure formed by this type of structure is not strong. The lever plate structure is prone to deformation or even damage when it is driven inside the rivet gun, which affects the stability of the push-pull transmission effect of the internal lever plate structure after the rivet gun trigger is pulled.

[0004] Therefore, how to design a lever plate structure with higher structural strength and more stable internal push-pull transmission effect of the rivet gun after the trigger is pulled is a problem that we urgently need to solve. Utility Model Content

[0005] This application provides a lever plate structure and a rivet gun, which have higher structural strength and more stable internal push-pull transmission effect after the wrench is pulled.

[0006] This application provides a lever structure for use in a rivet gun, the lever structure comprising:

[0007] Lever plate;

[0008] The first channel is set through the thickness of the lever plate to avoid the internal structure of the rivet gun.

[0009] The second channel is provided through the thickness of the lever plate to avoid the internal structure of the rivet gun. The second channel and the first channel are arranged sequentially along the length of the lever plate.

[0010] The support is provided on both sides of the lever plate along the width direction, and the lever plate can rotate through the support.

[0011] In one embodiment of this application, the lever plate has a first surface and a second surface arranged along the thickness direction, and the first surface of the lever plate has a first protrusion and a second protrusion respectively at both ends along the length direction.

[0012] In one embodiment of this application, the first protruding surface is arc-shaped; and / or, the second protruding surface is arc-shaped.

[0013] Accordingly, this application also provides a rivet gun, including a lever structure, and further comprising:

[0014] The housing has an intermediate cover and a gearbox, and a receiving space is formed between the intermediate cover and the gearbox to accommodate the support, so that the lever plate can rotate within the housing;

[0015] The gun head assembly is connected to the gearbox and has a telescopic rod that can extend and retract, which is connected to one end of the lever plate.

[0016] The wrench is mounted on the gearbox.

[0017] A connecting pin is movably mounted on the gearbox and extends from the inside of the gearbox to the outside. One end of the connecting pin is connected to the other end of the lever plate, and the other end of the connecting pin is connected to the wrench.

[0018] When the lever plate rotates inside the housing, the first and second channels can avoid the internal structure of the housing.

[0019] In one embodiment of this application, the rivet gun further includes a drive component disposed within the housing, and a first channel is used to avoid the drive component when the lever plate rotates.

[0020] In one embodiment of this application, the gearbox has a rotatably configured transmission member, one end of which is connected to a first gear that meshes with the output end of the drive component, and the other end of which is connected to a rotatably configured second gear.

[0021] The transmission component passes through the second channel so that the lever plate avoids the transmission component when it rotates.

[0022] In one embodiment of this application, the gun head assembly has a rotatably configured drive shaft. The drive shaft has a hollow structure, a telescopic rod is installed inside the drive shaft, and a second gear is disposed on the drive shaft to drive the drive shaft to rotate.

[0023] In one embodiment of this application, the gun head assembly has a rivet mounting mechanism and a transmission bolt, the transmission bolt being a split type, and the transmission bolt being installed at one end of the telescopic rod located inside the drive shaft;

[0024] When the telescopic rod moves into the drive shaft, the transmission bolt can be opened by the telescopic rod, so that the drive shaft drives the rivet installation mechanism to operate.

[0025] In one embodiment of this application, the rivet gun further includes a handle for a user to hold; and / or,

[0026] The middle cover is provided with a first mounting part, the gearbox is provided with a second mounting part, and the two ends of the transmission component are respectively installed in the first mounting part and the second mounting part.

[0027] In one embodiment of this application, the lever plate has a first surface and a second surface arranged along the thickness direction. The first surface of the lever plate has a first protrusion and a second protrusion respectively at both ends along the length direction. The first surface of the lever plate faces the connecting pin and the telescopic rod. The first protrusion is connected to the connecting pin and the second protrusion is connected to the telescopic rod.

[0028] The beneficial effects of this application are as follows: the lever plate and the support are integrated in a cross shape, which is simple in structure and easy to manufacture. The lever plate can rotate inside the rivet gun through the support on both sides, making installation convenient. Compared with the form of fixing by using pins and cam-shaped levers, it reduces the risk of oil leakage from the gearbox of the rivet gun. The overall structural strength of the lever plate with support on both sides is higher, and it is less likely to deform or be damaged when transmitting power inside the rivet gun. This effectively improves the accuracy of the lever plate transmission. After pulling the rivet gun wrench, the push-pull transmission effect through the lever plate is more stable, making the rivet gun's rivet-pulling action more reliable. Moreover, the first and second channels set on the lever plate can avoid the internal structure of the rivet gun, preventing interference between the lever plate and the internal structure of the rivet gun.

[0029] Furthermore, pressing the wrench once moves the connecting pin into the gearbox, which in turn presses the lever plate, causing the support to rotate within the receiving space. The lever plate rotates clockwise inside the rivet gun and presses the telescopic rod. The telescopic rod, under the pressure of the clockwise rotating lever plate, moves into the gun head assembly to continue transmitting pressure, enabling the rivet gun to begin pulling the rivet once. The rivet gun uses a cross-shaped integrated structure for the lever plate and support, which is simple in structure and easy to manufacture. The lever plate can rotate inside the rivet gun through the support on both sides, making installation convenient. Compared to the form of fixing with a pin and a cam-shaped lever, this reduces the risk of oil leakage from the gearbox of the rivet gun. The overall structural strength of the lever plate with support on both sides is higher, making it less prone to deformation and damage during transmission inside the rivet gun, effectively improving the accuracy of the lever plate transmission. After pulling the rivet gun wrench, the push-pull transmission effect through the lever plate inside is more stable, making the rivet gun's rivet pulling action more reliable. Moreover, the first and second channels set on the lever plate can avoid interference with the internal structure of the rivet gun. Attached Figure Description

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0046] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] Reference Figure 1 This application provides a lever structure for use in a rivet gun. The lever structure includes a lever plate 10, a first channel 11, a second channel 12, and a support portion 13.

[0048] Specifically, the lever plate 10 can be in the shape of a cross. Since steel has good durability and compressive strength, the lever plate 10 is usually made of high-strength steel. However, depending on the specific design requirements of the lever plate 10, alloy steel or other reinforcing materials may sometimes be used to improve its durability and wear resistance.

[0049] The first channel 11 is provided through the lever plate 10 along its thickness direction to avoid the internal structure of the rivet gun and prevent the lever plate 10 from interfering with its internal structure when it rotates inside the rivet gun.

[0050] The second channel 12 is provided through the lever plate 10 along its thickness direction to avoid the internal structure of the rivet gun. The second channel 12 and the first channel 11 are arranged sequentially along the length direction of the lever plate 10 to avoid interference between the lever plate 10 and its internal structure when the lever plate 10 rotates inside the rivet gun. The first channel 11 and the second channel 12 can be in the shape of a circle, ellipse, square, rectangle, rhombus, parallelogram, rhombus, regular polygon, etc.

[0051] The support part 13 is arranged on both sides of the lever plate 10 along the width direction of the lever plate 10. The lever plate 10 can rotate through the support part 13. The support part 13 and the lever plate 10 are integral structural components. The support part 13 can be a part of the lever plate 10, so that the lever plate 10 as a whole can be in a cross shape.

[0052] Through the above method, the lever plate 10 and the support part 13 form a cross-shaped integrated structure, which is simple in structure and easy to manufacture. The lever plate 10 can rotate inside the rivet gun through the support parts 13 on both sides, which is convenient to install. Compared with the form of fixing by using pins and cam-shaped levers, it reduces the risk of oil leakage in the gearbox 22 of the rivet gun. The overall structural strength of the lever plate 10 with the support parts 13 on both sides is higher, and it is less likely to deform or be damaged when transmitting in the rivet gun. It effectively improves the transmission accuracy of the lever plate 10. After pulling the rivet gun wrench 40, the push-pull transmission effect through the lever plate 10 is more stable, making the rivet gun's rivet pulling action more reliable. Moreover, the first channel 11 and the second channel 12 set on the lever plate 10 can avoid the internal structure of the rivet gun, avoiding interference between the lever plate 10 and the internal structure of the rivet gun.

[0053] In one embodiment of this application, the lever plate 10 has a first surface and a second surface arranged along the thickness direction. The first surface of the lever plate 10 has a first protrusion 14 and a second protrusion 15 at both ends along the length direction. The first protrusion 14 and the second protrusion 15 protrude beyond the first surface of the lever plate 10, and are integrally formed with the lever plate 10. When the lever plate 10 is installed inside a rivet gun, the first protrusion 14 on the first surface of the lever plate 10 can contact the connecting pin 50 inside the rivet gun, and the second protrusion 15 can contact the telescopic rod 31 inside the rivet gun. This ensures a more balanced force distribution between the two ends of the lever plate 10 and the connecting pin 50 and the telescopic rod 31, respectively, and helps to make the push-pull transmission effect of the lever plate 10 inside the rivet gun more stable and reliable.

[0054] In one embodiment of this application, the surface of the first protrusion 14 is arc-shaped; and / or, the surface of the second protrusion 15 is arc-shaped. By setting the surfaces of the first protrusion 14 and the second protrusion 15 to arc-shaped surfaces, when the lever plate 10 rotates inside the rivet gun, the arc-shaped surface of the first protrusion 14 can reduce the wear of the connecting pin 50, and the arc-shaped surface of the second protrusion 15 can reduce the wear of the telescopic rod 31, which helps to extend the service life of the rivet gun.

[0055] Accordingly, refer to Figures 2 to 5 as well as Figure 9 and Figure 10 This application also provides a rivet gun, including the lever structure in the above embodiments, and the rivet gun further includes: a housing 20, a gun head assembly 30, a wrench 40 and a connecting pin 50.

[0056] Specifically, the housing 20 has an intermediate cover 21 and a gearbox 22. A receiving space 23 is formed between the intermediate cover 21 and the gearbox 22 to accommodate the support part 13, so that the lever plate 10 can rotate inside the housing 20. The receiving space 23 can be a circular hole structure, and the support part 13 can be a rod structure, so that the support part 13 can be rotated after being inserted into the receiving space 23.

[0057] The gun head assembly 30 is connected to the gearbox 22. The gun head assembly 30 has a telescopic rod 31 that can extend and retract. The telescopic rod 31 is connected to one end of the lever plate 10. When the lever plate 10 rotates, it can drive the telescopic rod 31 to move within the gun head assembly 30.

[0058] The wrench 40 is rotatably mounted on the gearbox 22; a torsion spring may be installed on the wrench 40, which can automatically reset the wrench 40 after it is pressed.

[0059] A connecting pin 50 is movably mounted on the gearbox 22 and extends from the inside of the gearbox 22 to the outside. One end of the connecting pin 50 is connected to the other end of the lever plate 10, and the other end of the connecting pin 50 is connected to the wrench 40; further refer to Figure 11 and Figure 12 The gearbox 22 may be provided with a pin hole 225, through which the connecting pin 50 can pass through the gearbox 22. One end of the connecting pin 50 located inside the gearbox 22 may be provided with a limiting end, which can prevent the connecting pin 50 from falling out of the gearbox 22. When the connecting pin 50 has a limiting end, the connecting pin 50 is connected to the other end of the lever plate 10 through the limiting end.

[0060] By pressing the wrench 40 once, the connecting pin 50 moves into the gearbox 22. The connecting pin 50 presses against the lever plate 10, causing the support part 13 to rotate within the receiving space 23. The lever plate 10 rotates clockwise within the rivet gun and presses against the telescopic rod 31. The telescopic rod 31, under the pressure of the clockwise rotating lever plate 10, moves into the gun head assembly 30 to continue transmitting pressure, enabling the rivet gun to begin pulling the rivet once. The rivet gun uses a single cross-shaped structure where the lever plate 10 and the support part 13 are integrated, which is simple in structure and easy to manufacture. The lever plate 10 can rotate within the rivet gun via the support parts 13 on both sides, making installation convenient. Compared to the method of fixing with a pin and a cam-shaped lever, this method reduces the risk of oil leakage from the gearbox 22 of the rivet gun. The lever plate 10 with support parts 13 on both sides has higher overall structural strength and is less prone to deformation and damage when transmitting power within the rivet gun. This effectively improves the transmission accuracy of the lever plate 10. After pulling the rivet gun wrench 40, the push-pull transmission effect through the lever plate 10 is more stable, making the rivet gun's rivet-pulling action more reliable. Moreover, the first channel 11 and the second channel 12 set on the lever plate 10 can avoid the internal structure of the rivet gun, preventing interference between the lever plate 10 and the internal structure of the rivet gun.

[0061] In one embodiment of this application, reference is made to Figures 4 to 8 as well as Figure 11 The rivet gun also includes a drive component 60, which is disposed within the housing 20. A first channel 11 is used to avoid the drive component 60 when the lever plate 10 rotates. The housing 20 has a mounting position 201 for accommodating the drive component 60, which can be a motor. The output shaft of the drive component 60 can be located inside the first channel 11. When the lever plate 10 rotates, the output shaft of the drive component 60 remains within the first channel 11, preventing interference between the lever plate 10 and the drive component 60.

[0062] In one embodiment of this application, reference is made to Figure 2 and Figures 4 to 8 The gearbox 22 contains a rotatable transmission component 221. One end of the transmission component 221 is connected to a first gear 222 that meshes with the output end of the drive component 60, and the other end of the transmission component 221 is connected to a rotatable second gear 223. The transmission component 221 may be a drive shaft with teeth on its surface. The first gear 222 is fixedly mounted on the drive shaft. The output shaft of the drive component 60 has teeth that mesh with the first gear 222, enabling the drive component 60 to transmit power to the transmission component 221, causing it to rotate. At the same time, the teeth on the surface of the drive shaft mesh with the second gear 223, transmitting power to the second gear 223, causing it to rotate.

[0063] The transmission component 221 passes through the second channel 12 so that the lever plate 10 avoids the transmission component 221 when it rotates. When the lever plate 10 rotates in the housing 20, the transmission component 221 is always located in the second channel 12, thus avoiding interference between the lever plate 10 and the drive component 60.

[0064] In one embodiment of this application, reference is made to Figures 4 to 5 as well as Figure 8 and Figure 9 The rivet gun assembly 30 has a rotatably mounted drive shaft 301. The drive shaft 301 is a hollow structure, and the telescopic rod 31 is installed inside the drive shaft 301. A second gear 223 is mounted on the drive shaft 301 to drive the drive shaft 301 to rotate. The second gear 223 is fixedly mounted on the drive shaft 301, and the transmission component 221 drives the second gear 223 to rotate through the teeth on its surface, thereby transmitting the power of the drive component 60 to the drive shaft 301, thus enabling the rivet gun to perform the rivet pulling action.

[0065] In one embodiment of this application, reference is made to Figure 4 , Figure 6 and Figure 9 The gun head assembly 30 has a rivet mounting mechanism 302 and a transmission bolt 303. The transmission bolt 303 is a split type and is installed at one end of the telescopic rod 31 located inside the drive shaft 301. The rivet mounting mechanism 302 is located inside the gun head assembly 30. When the rivet gun is in use, the rivet can be installed in the rivet mounting mechanism 302 and riveted to the object through the rivet mounting mechanism 302.

[0066] When the telescopic rod 31 moves into the drive shaft 301, the transmission bolt 303 can be opened by the telescopic rod 31, so that the drive shaft 301 drives the rivet mounting mechanism 302 to operate. Specifically, pressing the wrench 40 moves the connecting pin 50 into the gearbox 22. The connecting pin 50 presses the lever plate 10, causing the support part 13 to rotate within the receiving space 23. The lever plate 10 rotates and presses the telescopic rod 31. The telescopic rod 31 moves along the drive shaft 301 towards the rivet mounting mechanism 302. At the same time, the telescopic rod 31 opens the transmission bolt 303, so that the transmission bolt 303 is connected to the rivet mounting mechanism 302 for transmission, thereby enabling the rivet gun to start a rivet pulling process.

[0067] In one embodiment of this application, reference is made to Figures 2 to 4 , Figure 6 , Figure 9 as well as Figure 11 The rivet gun also has a grip 70 for the user to hold. The grip 70 is located at the bottom of the gearbox 22 near the wrench 40. The grip 70 and the gearbox 22 can be an integral part of the structure, making it easy for the user to operate and press the wrench 40 after holding the grip 70.

[0068] It should be noted that the grip 70 and the gearbox 22 can also be separate structural components. When the grip 70 and the gearbox 22 are separate structural components, the grip 70 and the gearbox 22 can be made of different materials. The grip 70 can be made of plastic, and the gearbox 22 can be made of aluminum, which can facilitate heat dissipation of the gearbox 22.

[0069] And / or, further refer to Figure 10 and Figure 12 The intermediate cover 21 is provided with a first mounting part 211, and the gearbox 22 is provided with a second mounting part 224. The two ends of the transmission component 221 are respectively installed in the first mounting part 211 and the second mounting part 224. A first support sleeve can be installed in the first mounting part 211, and a second support sleeve can be installed in the second mounting part 224. The two ends of the transmission component 221 can be installed in the corresponding mounting parts through the first support sleeve and the second support sleeve. The axes of the two support sleeves coincide with each other, and the transmission component 221 can rotate under the action of the support sleeves.

[0070] In one embodiment of this application, reference is made to Figure 1 as well as Figures 4 to 8 The lever plate 10 has a first surface and a second surface arranged along the thickness direction. The first surface of the lever plate 10 has a first protrusion 14 and a second protrusion 15 at both ends along the length direction. The first surface of the lever plate 10 faces the connecting pin 50 and the telescopic rod 31. The first protrusion 14 is connected to the connecting pin 50, and the second protrusion 15 is connected to the telescopic rod 31. When the lever plate 10 is installed inside the rivet gun, the support portions 13 on both sides of the lever plate 10 are located in the receiving space 23 between the middle cover 21 and the gearbox 22. The first protrusion 14 on the first surface of the lever plate 10 can contact the connecting pin 50 inside the rivet gun, and the second protrusion 15 can contact the telescopic rod 31 inside the rivet gun. When the wrench 40 is pressed once, the connecting pin 50 drives the lever plate 10 to rotate clockwise around the support portion 13 through the first protrusion 14. At the same time, the telescopic rod 31 continues to transmit the pressure from the clockwise rotating second protrusion 15 to the gun head assembly 30, so that the rivet gun starts a rivet pulling process. By setting the first protrusion 14 and the second protrusion 15, the force on both ends of the lever plate 10 with the connecting pin 50 and the telescopic rod 31 can be more balanced, which helps to make the push-pull transmission effect of the lever plate 10 inside the rivet gun more stable and reliable.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
