Description
Technical Field
[0001] This utility model relates to the field of torque detection wrench technology, and in particular to a force-applying device for a torque detection wrench. Background Technology
[0002] Torque wrenches, as key tools for precisely controlling the tightening torque of bolts or nuts, are widely used in fields such as machinery manufacturing, automotive repair, aerospace, and construction engineering. With the increasing scale and precision of industrial equipment, the performance requirements for torque wrenches are rising, especially in terms of applicability, ease of operation, and safety. Furthermore, torque wrenches utilize specially configured extension rods for direct force application.
[0003] Traditional torque wrenches typically employ a fixed design for their force-applying devices, meaning the force-applying rod is an integral, non-removable structure from the wrench body. Even with detachable force-applying rods, replacing them requires auxiliary tools such as wrenches and screwdrivers, taking approximately one minute each time, thus impacting efficiency. Furthermore, when operating a torque wrench, the application of significant force or complex environments (such as working at heights or on oily surfaces) can easily cause the tool to slip from the hand, falling into equipment gaps, onto the ground, or from a height, rendering the operation impossible. Therefore, this application proposes a force-applying device for a torque-detecting wrench, providing a new technical solution to address the aforementioned technical problems. Utility Model Content
[0004] Based on this, it is necessary to provide a force-applying device for a torque testing wrench to address the aforementioned technical problems. Through the structural design of the force-applying component, the component can be quickly connected to or disassembled from the main body of the testing wrench. This allows for the replacement of the force-applying component with one that meets the required length, and the installation and disassembly of the force-applying component do not require any other tools, thereby improving the convenience of installation and disassembly.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A force-applying device for a torque-detecting wrench, which is used for torque detection.
[0007] The torque testing wrench's force-applying device specifically includes a testing wrench body and a wrench head detachably disposed at the front end of the testing wrench body. A force-applying component is disposed at the rear end of the testing wrench body. The force-applying component is detachably connected to the testing wrench body. A T-shaped connecting buckle is fixedly connected to the rear end of the testing wrench body. The force-applying component achieves connection and fixation with the testing wrench body by clamping the T-shaped connecting buckle.
[0008] The force-applying component includes an extended handle, with a fixed buckle and a movable buckle respectively provided at the ends of the extended handle. The fixed buckle and the movable buckle are symmetrically designed. The fixed buckle is fixedly connected to the extended handle, and the movable buckle is rotatably connected to the fixed buckle. A buckle groove is provided at the end of the fixed buckle and the movable buckle away from the extended handle. When the fixed buckle and the movable buckle are closed, they are clamped and connected to the T-shaped connecting buckle through the buckle groove.
[0009] As a preferred embodiment of the torque testing wrench force application device provided by this utility model, the force application component further includes a limiting sleeve. The limiting sleeve is sleeved on the outside of the fixed buckle, and the fixed buckle and the movable buckle are both located inside the limiting sleeve. The limiting sleeve and the fixed buckle, as well as the limiting sleeve and the extension handle, are all threadedly connected. The bottom of the extension handle is provided with a storage groove, and the lower end of the limiting sleeve can be stored inside the storage groove. When the lower part of the limiting sleeve is completely inside the storage groove, the upper part of the limiting sleeve separates from the movable buckle.
[0010] As a preferred embodiment of the torque detection wrench force application device provided by this utility model, the upper outer side of the limiting sleeve is provided with anti-slip texture.
[0011] In a preferred embodiment of the torque detection wrench force application device provided by this utility model, the bottom fixing plate of the force application component is connected to an anti-dislodgement component.
[0012] As a preferred embodiment of the torque detection wrench force application device provided by this utility model, the anti-disengagement component includes a connecting rope and a wristband. One end of the connecting rope is fixedly connected to the force application component, and the other end of the connecting rope is fixedly connected to the wristband.
[0013] In a preferred embodiment of the torque detection wrench force application device provided by this utility model, the connecting rope is a spiral elastic rope.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The torque testing wrench provided by this utility model has a force-applying device that allows the force-applying component to be quickly connected to or separated from the main body of the testing wrench through the structural design of the force-applying component. This allows the force-applying component to be replaced with one that meets the length requirements according to the usage needs. Furthermore, the installation and removal of the force-applying component do not require any other tools, thereby improving the convenience of installing or removing the force-applying component.
[0016] The torque testing wrench force application device provided by this utility model, through the design of the anti-dislodgement component, enables the connection between the testing wrench and the hand during use. In the event that the testing wrench is accidentally dislodged, the wrench can be retrieved in time, avoiding the phenomenon that the testing wrench cannot be retrieved when it falls due to working at height or in a confined space.
[0017] The torque testing wrench provided by this utility model has a force-applying device that allows torque testing to be performed in narrow spaces by using the wrench body and the wrench head together. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] As described in the background section, the torque wrench's force-applying device is usually a fixed design, meaning the force-applying rod is an integral part of the wrench body and cannot be disassembled. For some detachable force-applying rods, replacing the force-applying rod requires auxiliary tools such as wrenches and screwdrivers, and each replacement takes about 1 minute, affecting efficiency.
[0029] To solve this technical problem, this utility model provides a force-applying device for a torque-detecting wrench, which is used for torque detection.
[0030] For details, please refer to Figures 1-6 The torque testing wrench's force-applying device specifically includes: a testing wrench body 1, and a wrench head 2 detachably mounted at the front end of the testing wrench body 1. A force-applying component 3 is mounted at the rear end of the testing wrench body 1. The force-applying component 3 is detachably connected to the testing wrench body 1. A T-shaped connecting buckle 5 is fixedly connected to the rear end of the testing wrench body 1. The force-applying component 3 achieves connection and fixation with the testing wrench body 1 by clamping the T-shaped connecting buckle 5.
[0031] The force-applying component 3 includes an extended handle 6. The ends of the extended handle 6 are respectively provided with a fixed buckle 7 and a movable buckle 8. The fixed buckle 7 and the movable buckle 8 are symmetrically designed. The fixed buckle 7 is fixedly connected to the extended handle 6, and the movable buckle 8 is rotatably connected to the fixed buckle 7. The ends of the fixed buckle 7 and the movable buckle 8 away from the extended handle 6 are provided with buckle grooves. When the fixed buckle 7 and the movable buckle 8 are closed, they are clamped and connected to the T-shaped connecting buckle 5 through the buckle grooves.
[0032] The torque testing wrench force application device provided by this utility model, through the structural design of the force application component 3, enables the force application component 3 to be quickly connected or disassembled with the main body 1 of the testing wrench, so that the force application component 3 that meets the length requirements can be replaced according to the usage needs. Moreover, the installation and disassembly of the force application component 3 do not require other tools, thereby improving the convenience of installing or disassembling the force application component 3.
[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] Example 1:
[0035] Please refer to Figures 1-6 A torque testing wrench force application device includes: a testing wrench body 1, and a wrench head 2 detachably disposed at the front end of the testing wrench body 1. A force application component 3 is disposed at the rear end of the testing wrench body 1. The force application component 3 is detachably connected to the testing wrench body 1. A T-shaped connecting buckle 5 is fixedly connected to the rear end of the testing wrench body 1. The force application component 3 achieves connection and fixation with the testing wrench body 1 by clamping the T-shaped connecting buckle 5.
[0036] Specifically, in order to connect the force-applying component 3 with the main body 1 of the testing wrench, the force-applying component 3 includes an extended handle 6. The ends of the extended handle 6 are respectively provided with a fixed buckle 7 and a movable buckle 8. The fixed buckle 7 and the movable buckle 8 are symmetrically designed. The fixed buckle 7 is fixedly connected to the extended handle 6, and the movable buckle 8 is rotatably connected to the fixed buckle 7. The ends of the fixed buckle 7 and the movable buckle 8 away from the extended handle 6 are provided with buckle grooves. When the fixed buckle 7 and the movable buckle 8 are closed, they are clamped and connected to the T-shaped connecting buckle 5 through the buckle grooves.
[0037] Furthermore, to achieve the limiting effect after the fixed buckle 7 and the movable buckle 8 are closed, the force-applying component 3 also includes a limiting sleeve 9. The limiting sleeve 9 is sleeved on the outside of the fixed buckle 7, and both the fixed buckle 7 and the movable buckle 8 are located inside the limiting sleeve 9. The limiting sleeve 9 is threadedly connected to the fixed buckle 7 and to the extension handle 6. The bottom of the extension handle 6 has a storage groove 10, and the lower end of the limiting sleeve 9 can be stored inside the storage groove 10. When the lower part of the limiting sleeve 9 is completely inside the storage groove 10, the upper part of the limiting sleeve 9 separates from the movable buckle 8. In order to facilitate the rotational adjustment of the limiting sleeve 9, the upper outer side of the limiting sleeve 9 is provided with anti-slip texture 11.
[0038] It can be seen that when replacing the force-applying component 3, by rotating the limiting sleeve 9, the limiting sleeve 9 is moved downward until the bottom of the limiting sleeve 9 is completely inside the receiving groove 10, thereby separating the top of the limiting sleeve 9 from the movable buckle 8. Then, by flipping the movable buckle 8, the fixed buckle 7 and the movable buckle 8 are no longer clamping the T-shaped connecting buckle 5, thus achieving the separation of the force-applying component 3 from the testing wrench body 1. During installation, the T-shaped connecting buckle 5 is moved into the buckle groove opened in the fixed buckle 7, and then by flipping... Rotate the movable buckle 8 so that its buckle groove fits into the T-shaped connecting buckle 5, thereby clamping the T-shaped connecting buckle 5 through the fixed buckle 7 and the movable buckle 8. Then, rotate the limiting sleeve 9 so that the limiting sleeve 9 moves upward and is fitted onto the outside of the fixed buckle 7 and the movable buckle 8, thereby limiting the flipping of the movable buckle 8 and maintaining the state in which the fixed buckle 7 and the movable buckle 8 clamp the T-shaped connecting buckle 5, thus completing the connection between the force-applying component 3 and the main body 1 of the testing wrench.
[0039] Furthermore, to prevent the testing wrench from accidentally slipping out of the hand and making it impossible to continue working, the bottom fixing plate of the force-applying component 3 is connected to the anti-slip component 4. When in use, the testing wrench is connected to the hand through the anti-slip component 4, so that the testing wrench can be retrieved in time if it slips out of the hand.
[0040] Example 2:
[0041] The force application device of the torque detection wrench provided in Embodiment 1 is further optimized, specifically, as follows: Figure 3 As shown, the anti-slip assembly 4 includes a connecting rope and a wristband. One end of the connecting rope is fixedly connected to the tensioning assembly 3, and the other end of the connecting rope is fixedly connected to the wristband. The connecting rope is a spiral elastic rope.
[0042] With the above structural design, when in use, the wristband is put on the wrist. If the testing wrench is accidentally dropped, the testing wrench is connected by an elastic cord, so that the testing wrench can be picked up by following the elastic cord. This avoids the phenomenon that the testing wrench cannot be retrieved when it falls due to working at height or in a confined space.
