Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, and specifically discloses a torque wrench with a handle having a shock-absorbing function. Background Art

[0002] Torque wrench is a commonly used tool for accurately controlling the tightening torque of bolts and nuts. It is widely used in machinery manufacturing, automobile maintenance, aerospace and other fields. Traditional torque wrenches have some problems during use, which affect the comfort and work efficiency of operation. The existing hardware wrench (publication number: CN107253160A) has at least the following disadvantages:

[0003] 1. Existing torque wrenches usually do not have a special shock-absorbing device. During the process of applying torque, the vibration generated during the operation will be directly transmitted to the user's hand, which will easily cause hand fatigue after long-term use, and may even cause hand injury, affecting the stability and accuracy of the operation. Therefore, a device that can achieve a shock-absorbing function is urgently needed.

[0004] 2. Existing torque wrenches lack effective lighting means when used in low-light environments, such as at night or in narrow spaces, and users have to rely on external light sources or flashlights for assistance. This not only increases the complexity of operation, but may also lead to operational errors due to insufficient light, so there is an urgent need for a device that can illuminate the system at night.

[0005] 3. Existing torque wrenches Traditional torque wrenches usually only have torque measurement and control functions, and lack the integration of other auxiliary tools. When users need to use other tools such as screwdrivers, they must carry and replace tools additionally, which increases the inconvenience and time cost of operation, so there is an urgent need for a multifunctional device. Utility Model Content

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a torque wrench with a handle having a shock absorbing function, comprising a torque wrench body, a torque head is installed on the top of the torque wrench body, the connection between the torque wrench body and the torque head is fixedly connected by bolts, a control panel is installed in front of the torque wrench body, a spring damper is installed at the bottom of the torque wrench body, a rotating shaft is installed at the bottom of the spring damper, a screwdriver is installed on the rotating shaft, an LED lighting lamp is installed on the top side of the torque wrench body, and a gear is installed inside the torque head.

[0008] Preferably, a circuit board is installed inside the torque wrench body.

[0009] Preferably, an integrated power supply is installed above the circuit board.

[0010] Preferably, electrical wires are passed through the top of the integrated power supply.

[0011] Preferably, a controller is installed on the other side of the electric wire.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can effectively absorb and reduce the vibration generated during operation by installing a spring damper inside the handle, significantly reducing the fatigue of the user's hands. When used for a long time, the comfort of the user's hands is greatly improved, which helps to maintain the continuity and stability of the operation.

[0015] 2. The LED light on the top of the handle of this utility model provides users with sufficient lighting in low-light environments, helping to improve visibility in the work area and making operations more precise and safer. The built-in lighting function is particularly important when working at night or in narrow spaces.

[0016] 3. The utility model integrates a detachable screwdriver at the bottom of the handle, making the torque wrench more than just a single-function tool.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example

[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] A torque wrench with a shock absorbing function on its handle comprises a torque wrench body, a torque head is mounted on the top of the torque wrench body, the torque wrench body and the torque head are fixedly connected at the connection point by bolts, a control panel is mounted in front of the torque wrench body, a spring damper is mounted on the bottom of the torque wrench body, a rotating shaft is mounted on the bottom of the spring damper, a screwdriver is mounted on the rotating shaft, an LED lighting lamp is mounted on the top side of the torque wrench body, a gear is mounted inside the torque head, a circuit board is mounted inside the torque wrench body, an integrated power supply is mounted above the circuit board, wires are passed through the top of the integrated power supply, a controller is mounted on the other side of the wires, and a USB charging port is opened above the control panel.

[0027] In this embodiment, the spring damper preferably adopts the spring damper of the model Progressive Pitch Damping produced by Force Technology. The progressive pitch damping design can provide a smoother damping effect, adapt to different load changes, and reduce sudden impacts and vibrations. Due to the smoother damping effect, the user's comfort during operation is significantly improved. Especially during long-term use, the progressive pitch damping can effectively reduce the wear and fatigue of the equipment and extend its service life.

[0028] In this embodiment, in a long-term use test, users of traditional torque wrenches reported hand fatigue after an average of 30 minutes, while users of the utility model reported the same fatigue after 60 minutes, and the use time was doubled. In a precision test of 100 operations, the operation error rate of using a traditional torque wrench was 8%, while the operation error rate of using the utility model was only 2%, and the accuracy was improved by 75%. Reducing vibration transmission helps reduce the risk of hand injuries caused by long-term use of tools, such as tendonitis or other repetitive strain injuries. By improving the shock absorption performance of the tool, a safer use experience can be provided to users.

[0029] It should be noted that in the test conducted by the utility model in an environment with insufficient light, the operation error rate of the traditional torque wrench was 15%, while the operation error rate of the utility model was 5%, which was a 66% reduction. The built-in LED light eliminates the user's dependence on external light sources and simplifies the operation process. Users no longer need to hold a flashlight or adjust the angle of the work light. They can complete the lighting and operation with one hand, which improves work efficiency. In a simulated night operation task, the average time for traditional torque wrench users to complete the task was 20 minutes, while the average time for users using the utility model to complete the task was 15 minutes, which was a 25% reduction. There is no need to frequently adjust or move the external light source. The built-in LED light allows users to focus more on the actual operation task, saving preparation time and energy for adjusting the light, thereby improving overall work efficiency.

[0030] Compare Projects Traditional torque wrench Torque wrench with shock absorption function Percentage increase User hand fatigue Fatigue starts after 30 minutes Fatigue starts after 60 minutes +100% Operation error rate 8% 2% -75% Proportion of users with hand discomfort 35% 10% -71% Operation error rate in low light environment 15% 5% -66% Preparing and adjusting light timing 5 minutes 1 minute -80%
