Description
Technical Field
[0001] This utility model relates to a riveting device and a riveting nut, specifically a handheld riveting device and a riveting nut. Background Technology
[0002] Blind rivets are primarily used in riveting. These rivets have a hollow structure with a shank in the middle, the end of which is rounded and necked. During operation, a suitable hole is first drilled in the parts to be riveted. The rivet is inserted into the hole, and then the chuck of the rivet gun is used to hold the shank, with the gun tip pressing against the rivet head. The rivet gun applies tension, causing the shank to engage. The pressure on the rivet head forces the softer rivet head to expand outwards into a flange shape, thus tightly bonding the materials together. Tension continues to be applied until the rivet breaks at the neck and is pulled out, completing the riveting process.
[0003] Common handheld riveting devices, especially existing rivet guns, mostly use air as a power source to drive the riveting operation. These air-powered rivet guns require corresponding air source equipment, such as air compressors, and also necessitate the installation of air hoses and other supporting facilities. In practical applications, especially in confined spaces where air source equipment is inconvenient to install, or in environments without readily available air sources, the use of such rivet guns is severely limited, making it impossible to perform riveting work properly. Furthermore, the screws used in existing riveting connections generally require a core-pulling operation. During the riveting process, the core-pulling operation not only increases the complexity of the operation steps but also demands a relatively high level of skill from the operator. The operator needs to precisely control the pulling force and stroke of the rivet gun to ensure the successful completion of the core-pulling process; otherwise, problems such as incomplete rivet breakage and weak riveting may occur. Utility Model Content
[0004] The purpose of this utility model is to provide a handheld riveting device and a riveting nut. By providing a screw, the external thread of the screw engages with the internal thread in the body of the riveting nut. The rotation of the screw causes the riveting nut to deform at the groove. The deformed shape is similar to the "I" shape, thereby achieving rapid riveting. The riveting device has a simple structure and is easy to carry.
[0005] To address the problems of existing technologies, this utility model provides a handheld riveting device for inserting a rivet nut body into a hole in a product, causing the rivet nut body to deform and lock onto one side of the hole. The device includes a main body and a riveting assembly. The main body is equipped with a clamping component for fixing the riveting assembly and a rotary drive component for rotating the clamping component. The riveting assembly includes a screw with external threads. One end of the riveting assembly has a first connecting groove. The screw engages with the internal threads in the rivet nut body. A groove is formed on the outer ring of the rivet nut body near the nut. During riveting, the rivet nut body can be screwed onto the outside of the riveting assembly. When the rivet nut body is inserted into the riveting hole, the rotation of the riveting assembly causes the rivet nut body to press against the groove. The two ends of the rivet nut body near the groove expand outwards, causing the deformed position of the rivet nut body to lock onto one side of the hole.
[0006] Preferably, the device includes an extension component. The main body is provided with a clamping member for fixing the extension component. The main body is also provided with a rotary drive for rotating the clamping member. The extension component includes a guide rod that can be inserted into the clamping member. A telescopic rod that can slide in the guide rod is provided in the guide rod. One end of the telescopic rod is provided with a first limiting plug that can be inserted into a first connecting groove and dock with a screw. A second connecting groove is provided at the end of the guide rod away from the telescopic rod.
[0007] Preferably, the telescopic rod has several limiting strips on its outer side along its length, and the guide rod also has a sliding groove that cooperates with the limiting strips along its length.
[0008] Preferably, a fixing component for fastening the telescopic rod is also provided on the outside of the guide rod near the junction of the guide rod and the telescopic rod.
[0009] Preferably, the device includes a universal joint assembly. The main body is provided with a clamping member for fixing the universal joint assembly. The main body is also provided with a rotary drive member for rotating the clamping member. The universal joint assembly includes a first universal joint and a second universal joint, which are movably connected. A first connecting rod is fixed to the end of the first universal joint away from the second universal joint. A first insert is connected to the other end of the second universal joint away from the first universal joint. The first insert can be inserted into a second connecting slot to dock with the extension assembly. The first connecting rod can be inserted into the clamping member.
[0010] Preferably, the device includes a universal joint assembly. The main body is provided with a clamping member for fixing the universal joint assembly. The main body is also provided with a rotary drive member for rotating the clamping member. The universal joint assembly includes a first universal joint and a second universal joint, which are movably connected. A first connecting rod is fixed to the end of the first universal joint away from the second universal joint. A first insert is connected to the other end of the second universal joint away from the first universal joint. The first insert can be inserted into a first connecting groove to mate with a riveting assembly. The first connecting rod can be inserted into the clamping member.
[0011] Preferably, the device includes an extension member, and the main body is provided with a clamping member for fixing the extension member. The main body is also provided with a rotary drive member for rotating the clamping member. The extension member includes a flexible rod, one end of which is connected to a second connecting rod that can be inserted into the clamping member. The other end of the flexible rod is connected to a second insert that can be inserted into a first connecting groove to dock with the riveting assembly.
[0012] A rivet nut is fixed by a handheld rivet device as described in the above solution.
[0013] The advantages of this utility model compared to the prior art are:
[0014] 1. This application utilizes a screw with external threads. These external threads engage with the internal threads of the rivet nut body. When the screw rotates, it drives the lower end of the rivet nut body towards the nut. Because the rivet nut body has grooves, it deforms at the groove location, forming an "I" shape, thus achieving the riveting of the components. Furthermore, this riveting assembly has good compatibility and can be adapted to various handheld devices, such as handheld drills.
[0015] 2. In some products, such as some molds, some riveting holes are located at the bottom of the mold, where other components may interfere. To avoid interference from surrounding components, this application provides an extension component. The extension component can be installed in the clamping part, the telescopic rod can slide within the guide rod to adjust its length, and the fixing component can fix the telescopic rod, thereby enhancing the adaptability of the handheld device.
[0016] 3. When the riveting holes are too close to other components on the product (such as some pillars), the main body may be unable to transmit power to the riveting assembly due to interference from these components. To address this, this application provides a universal joint assembly. The universal joint assembly includes a first universal joint and a second universal joint. The first insert on the second universal joint can either connect to the extension assembly or directly connect to the riveting assembly, thereby changing the relative angle between the riveting assembly and the main body. Alternatively, a flexible rod can be used to connect to the riveting assembly, which in turn connects to the main body. This allows the main body to transmit power to the riveting assembly at any position, avoiding interference from other components on the product. Attached Figure Description

Detailed Implementation
[0030] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0031] Example 1: Refer to Figures 1-3 As shown, this utility model provides a handheld riveting device for inserting a rivet nut body 100 into a hole in a product, causing the rivet nut body 100 to deform and lock onto one side of the hole. It includes a main body 1 and a riveting assembly 2. The main body 1 is provided with a clamping member 11 for fixing the riveting assembly 2, and a rotary drive member for rotating the clamping member 11. The riveting assembly 2 includes a screw 21 with external threads, and a first connecting groove 22 is provided at one end of the riveting assembly 2. The screw 21 engages with the internal thread of the rivet nut body 100. The outer ring of the rivet nut body 100 has a groove 1001 near the nut. When riveting is performed, the rivet nut body 100 can be screwed onto the outside of the riveting assembly 2. When the rivet nut body 100 is inserted into the riveting hole, the rivet nut body 100 can squeeze the groove 1001 when the riveting assembly 2 rotates. The two ends of the rivet nut body 100 near the groove 1001 will expand outward, causing the deformed position of the rivet nut body 100 to be stuck on one side of the hole.
[0032] When the screw 21 rotates, it drives the lower end of the rivet nut body 100 to move towards the nut. Because the rivet nut body 100 has a groove 1001, it deforms at the groove 1001, forming an "I" shape, thus achieving the riveting of the components. Furthermore, this rivet assembly 2 has good compatibility and can be adapted to various handheld devices, such as handheld drills.
[0033] Example 2: Reference Figures 4-6 As shown, the device includes an extension component 3. A clamping member 11 for fixing the extension component 3 is provided on the main body 1. A rotary drive for rotating the clamping member 11 is also provided in the main body 1. The extension component 3 includes a guide rod 31 that can be inserted into the clamping member 11, and a telescopic rod 33 that can slide within the guide rod 31. One end of the telescopic rod 33 has a first limiting insert 332 that can be inserted into a first connecting groove 22 to connect with a screw 21. The end of the guide rod 31 away from the telescopic rod 33 has a second connecting groove 311. Several limiting strips 331 are provided on the outer side of the telescopic rod 33 along its length. A sliding groove that cooperates with the limiting strips 331 is also provided inside the guide rod 31 along its length. A fixing component 32 for fastening the telescopic rod 33 is also provided on the outer side of the guide rod 31 near the junction of the guide rod 31 and the telescopic rod 33.
[0034] The telescopic rod 33 is a key component for adjustable length. It slides within the guide rod 31, allowing adjustment of the entire length of the extension assembly 3 as needed. At one end of the telescopic rod 33, a first limiting insert 332 is provided. This insert precisely inserts into the first connecting groove 22 of the riveting assembly 2 and aligns with the screw 21. Furthermore, to ensure stable sliding of the telescopic rod 33 within the guide rod 31, several limiting strips 331 are provided along its length on the outer side of the telescopic rod 33. These limiting strips 331 cooperate with the sliding grooves inside the guide rod 31, effectively preventing the telescopic rod 33 from shifting or wobbling during sliding. The fixing assembly 32 secures the telescopic rod 33, ensuring that it does not slide or shift unnecessarily due to external forces during the riveting operation.
[0035] The extension component 3 can be installed into the clamping component 11, the telescopic rod 33 can slide within the guide rod 31 to adjust the length, and the fixing component 32 can fix the telescopic rod 33, thereby enhancing the adaptability of the handheld device.
[0036] Example 3: Reference Figures 7-8As shown, the device includes a universal joint 4. A clamping member 11 for fixing the universal joint 4 is provided on the main body 1. A rotary drive member for rotating the clamping member 11 is also provided in the main body 1. The universal joint 4 includes a first universal joint 41 and a second universal joint 42. The first universal joint 41 and the second universal joint 42 are movably connected. A first connecting rod 411 is fixed to one end of the first universal joint 41 away from the second universal joint 42. A first insert 421 is connected to the other end of the second universal joint 42 away from the first universal joint 41. The first insert 421 can be inserted into the second connecting groove 311 to dock with the extension component 3. The first connecting rod 411 can be inserted into the clamping member 11.
[0037] The design of the first universal joint 41 and the second universal joint 42 allows them to rotate freely in multiple planes, thus providing a wide range of operating angles. The operator can adjust the relative angle between the first universal joint 41 and the second universal joint 42, as well as the connection method between the universal assembly 4 and the main body 1 and the extension assembly 3, as needed. This high degree of flexibility enables the riveting device to perform precise riveting operations in various complex or confined spaces.
[0038] Example 4: Reference Figure 9 As shown: It includes a universal assembly 4, and a clamping member 11 for fixing the universal assembly 4 is provided on the main body 1. The main body 1 is also provided with a rotary drive member for rotating the clamping member 11. The universal assembly 4 includes a first universal joint 41 and a second universal joint 42. The first universal joint 41 and the second universal joint 42 are movably connected. A first connecting rod 411 is fixed to one end of the first universal joint 41 away from the second universal joint 42. A first insert 421 is connected to the other end of the second universal joint 42 away from the first universal joint 41. The first insert 421 can be inserted into the first connecting groove 22 to dock with the riveting assembly 2. The first connecting rod 411 can be inserted into the clamping member 11.
[0039] Example 5: Reference Figures 9-12 The diagram shows an extension member 5. A clamping member 11 for fixing the extension member 5 is provided on the main body 1. A rotary drive member for rotating the clamping member 11 is also provided in the main body 1. The extension member 5 includes a flexible rod 51. One end of the flexible rod 51 is connected to a second connecting rod 511, which can be inserted into the clamping member 11. The other end of the flexible rod 51 is connected to a second insert 512, which can be inserted into the first connecting groove 22 to dock with the riveting assembly 2.
[0040] The flexible rod 51 is the core of the extension 5. It is made of high-strength and high-elasticity material and can bend and twist while maintaining sufficient rigidity. By introducing the extension 5, especially the flexible rod 51 as its core component, the flexibility and adaptability of the device are greatly enhanced, thus adapting to various complex operating spaces.
[0041] The flexible rod 51 is connected to the riveting assembly 2, and then the riveting assembly 2 is connected to the main body 1. In this way, the main body 1 can transmit power to the riveting assembly 2 at any position, avoiding interference from other parts of the product.
[0042] A rivet nut is fixed by a handheld rivet device as described in the above solution.
[0043] Working Principle: In use, the riveting assembly 2 is first connected to the clamping member 11. The screw 21 has an external thread that meshes with the internal thread of the rivet nut body 100. When the screw 21 rotates, it moves the lower end of the rivet nut body 100 towards the nut. Because the rivet nut body 100 has a groove 1001, it deforms at the groove 1001, forming an "I" shape, thus achieving the riveting of the components. For cases with greater depth and the riveting hole located at the bottom of the product, an extension assembly 3 is provided to avoid interference from surrounding components. The extension assembly 3 can be installed in the clamping member 11, where the telescopic rod 33 can slide within the guide rod 31 to adjust the length. The fixing assembly 32 can fix the telescopic rod 33, enhancing the adaptability of the handheld device. When the product's riveting hole is too close to other components such as a column, the main body 1 may be unable to transmit power to the riveting assembly 2 due to interference from these components. To this end, the device is equipped with a universal joint 4, which includes a first universal joint 41 and a second universal joint 42. The first insert 421 on the second universal joint 42 can either connect to the extension component 3 or directly connect to the riveting component 2, thereby changing the relative angle between the riveting component 2 and the main body 1. Alternatively, a flexible rod 51 can be used to connect to the riveting component 2, and then the riveting component 2 can connect to the main body 1. In this way, the main body 1 can transmit power to the riveting component 2 at any position, avoiding interference from other parts of the product.
[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
