Description

Technical Field

[0001] This utility model relates to the field of rivet nut technology, specifically a wrench for securing rivet nuts. Background Technology

[0002] Rivet nuts, also known as pull rivet nuts or press rivet nuts, are fasteners installed using a riveting process. They are used to form threaded connections on metal sheets or pipes. Due to their efficiency and stability, rivet nuts are widely used and have become one of the important fasteners in modern industry. Their installation process is simple, requiring no welding or tapping, making them particularly suitable for connecting thin plates and pipes.

[0003] In certain special environments, such as when the upper side of the rivet nut is obscured by a sheet metal and the space is confined, traditional rivet nut guns are difficult to use, requiring specific tools to install the rivet nut. Patent document publication number 206445109 U provides a rivet nut wrench assembly, including a fixed wrench and a quick-release wrench. The fixed wrench has a screw threadedly connected to the front end of a screw rod that is threaded onto the rivet nut to be installed. A nut is screwed onto the screw rod. The quick-release wrench's wrench head is fitted onto the nut. This combination of a fixed wrench and a quick-release wrench structure allows for quick installation of the rivet nut. However, the quick-release wrench requires 360-degree rotation to operate, which is difficult to achieve if space is limited. Therefore, based on actual usage, we have improved upon the aforementioned prior art. Utility Model Content

[0029] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a wrench for securing rivet nuts, comprising a riveting structure 1, an adjusting knob 2, and a rivet puller 8. The rivet puller 8 is an existing structure, namely a component that rivets the rivet nut by pulling it along the rivet nut rod 9.

[0031] The riveting structure 1 has a fixed wrench 5 connected to its bottom, an adjustable wrench 6 movably mounted on its left outer wall, and a pin 7 rotatably mounted on its top. A connecting sleeve 101 is horizontally mounted on the top left end of the riveting structure 1, with an adjusting knob 2 connected to its outer end. A rivet puller 8 is horizontally mounted on the top right end of the riveting structure 1, with a rivet nut rod 9 mounted on its outer end. The left end of the rivet puller 8 passes through the riveting structure 1 and connects to the connecting sleeve 101. The pin 7 passes through the riveting structure 1 and is inserted into the adjustable wrench 6. A movable groove matching the adjustable wrench 6 is provided on the left outer wall of the riveting structure 1. Please refer to [link / reference needed]. Figure 1 Furthermore, based on existing technology, when the rivet nut rod 9 is screwed into the rivet nut, the rivet nut is fixed by pressing the movable wrench 6, and the operation is completed by screwing the rivet nut rod 9 out again. In some specific environments, such as when the rivet nut is blocked and the riveting device cannot achieve effective riveting operation vertically, the riveting structure 1 can be extended into the top of the rivet nut, and the installation operation can be carried out by selecting a rivet nut rod 9 of appropriate size.

[0032] An adjustment component 3 is connected to the outer end of the adjustment knob 2. The adjustment knob 2 is an existing structure on the riveting device to achieve the adjustment function, so that the rivet nut rod 9 can be screwed into or removed from the rivet nut, which facilitates the installation work.

[0033] An auxiliary component 4 is connected to the outer right side of the riveting structure 1. Because the environment used in this application requires a certain degree of verticality when the rivet nut rod 9 is installing the rivet nut, the auxiliary component 4 can abut against the plate on which the rivet nut is installed, so that the operation can maintain verticality while ensuring that the rivet nut will not deviate during the installation process.

[0034] Preferably, the adjustment assembly 3 includes a pressing rod 31, a support shaft 32 connected to the top right outer wall of the pressing rod 31, a limiting disc 33 installed on the outer wall of the support shaft 32, and a locking tooth 34 installed on the end of the support shaft 32. The locking tooth 34 is a Z-shaped structure with a sharp head, and both the locking tooth 34 and the limiting disc 33 are located in the inner cavity of the adjustment knob 2.

[0035] Preferably, a fixing ring 21 is connected to the inner wall of the adjusting knob 2, and the inner wall of the fixing ring 21 is evenly arranged with helical teeth 22 that match the locking teeth 34. The adjusting knob 2 is provided with a limiting circular groove that matches the limiting circular piece 33, and the cross-sectional diameter of the limiting circular groove is larger than the cross-sectional diameter of the limiting circular piece 33.

[0036] It should be noted that you should refer to [link / reference]. Figure 2 and Figure 3 In confined spaces where the adjustment knob 2 cannot be touched manually, it can be adjusted by rotating the pressing rod 31. When the pressing rod 31 is rotated, it drives the locking teeth 34 to rotate. While the locking teeth 34 rotates within multiple sets of helical teeth 23, they are locked by two sets of helical teeth 23. When the pressing rod 31 is rotated back and forth, the adjustment knob 2 can be adjusted by the cooperation of the locking teeth 34 and the helical teeth 23. The diameter of the limiting circular groove in the adjustment knob 2 is larger than the diameter of the limiting circular piece 33. This allows the limiting circular piece 33 to rotate and be limited within the adjustment knob, while the locking teeth 34 and the helical teeth 23 can be separated and engaged by lifting the pressing rod 31, providing the adjustment knob 2 with flexible application space.

[0037] Preferably, the auxiliary component 4 includes a connecting plate 41, a fixed sleeve 42 connected to the top of the connecting plate 41, a telescopic sleeve 43 movably inserted into the top of the fixed sleeve 42, and a damping baffle 44 connected to the end of the telescopic sleeve 43. It should be noted that... (See also...) Figure 1 and Figure 4 The telescopic sleeve 43 can extend and retract within the fixed sleeve 42. The telescopic sleeve 43 is inserted into the fixed sleeve 42, and a spring is connected to the bottom of the telescopic sleeve 43. The bottom of the spring is connected to the bottom of the inner cavity of the fixed sleeve 42 to achieve the effect of telescopic support.

[0038] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0039] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
