Description

Technical Field

[0001] The utility model relates to the technical field of lithium-powered wrenches, in particular to a silencer-type shock-absorbing lithium-powered wrench. Background Art

[0002] An electric wrench is a power tool used to remove or tighten screws, bolts, or nuts. Lithium-ion powered wrenches, in particular, are cordless, portable, and lightweight. They are widely used in a wide range of applications, including reinforcement of building beams, slabs, columns, and walls, as well as renovations, wall installations, brackets, railings, billboards, air conditioner outdoor units, guide rails, satellite receivers, elevators, steel structure factories, and vehicle repair. When an electric wrench is in operation, the movement of internal components, such as the impact hammer, can generate significant vibration and noise, impacting the user's work efficiency and quality.

[0003] The existing device mainly reduces the vibration and noise of the wrench through structures such as shock-absorbing plates and sound-insulating materials. The existing technology is mostly similar to a portable lithium-powered wrench. The structure with patent number CN217620301U includes a torque output mechanism, a torque amplification mechanism, a power unit, an electronic control unit, a lithium battery pack and a handle mechanism. It is characterized in that the handle mechanism is provided with a first shock-absorbing part and a second shock-absorbing part, and the first shock-absorbing part and the second shock-absorbing part are arranged at intervals on the outside of the handle mechanism. Through the cooperation of the first shock-absorbing part and the second shock-absorbing part, the shock-absorbing performance of the lithium-powered wrench is improved, which helps the user not feel discomfort due to the vibration of the motor when operating the equipment. However, there are still areas that can be optimized in this device.

[0004] Existing devices mainly use shock-absorbing plates to reduce the vibration of the wrench, making it difficult for some devices to effectively reduce the vibration transmission between the power unit and the handle, resulting in hand fatigue and arm soreness after long-term use of some devices. At the same time, some devices mainly reduce the noise of the power unit by filling silencer cotton, making it difficult for some devices to install auxiliary silencer accessories, resulting in some devices generating large noise during operation, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above technical problems, this application proposes a silencer-type shock-absorbing lithium-powered wrench. Utility Model Content

[0005] The purpose of the present utility model is to provide a silencer-type shock-absorbing lithium-powered wrench to solve the problem that the existing devices proposed in the above-mentioned background technology mainly reduce the vibration of the wrench by using a shock-absorbing plate, which makes it difficult for some devices to effectively reduce the vibration transmission between the power unit and the handle, thereby causing hand fatigue and arm soreness after long-term use of some devices. At the same time, some devices mainly reduce the noise of the power unit by filling silencer cotton, making it difficult for some devices to install auxiliary silencer accessories, thereby causing some devices to generate large noise during operation.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a silencer-type shock-absorbing lithium-ion battery wrench, comprising a power unit, a torque output mechanism being provided on the left side of the power unit, a fixed cylinder being sleeved on the outer wall of the power unit, an electric control handle being fixedly connected to the bottom of the electric control handle, a lithium battery assembly being fixedly connected to the bottom of the electric control handle, and a muffler being provided above the fixed cylinder;

[0007] The inner wall of the fixed cylinder is provided with a shock-absorbing mechanism, and the shock-absorbing mechanism includes a sliding sleeve. The outer wall of the sliding sleeve is fixedly connected to the upper and lower sides of the inner wall of the fixed cylinder. The top of the fixed cylinder is provided with a clamping mechanism, and the clamping mechanism includes a clamping seat. The bottom of the clamping seat is fixedly connected to the middle of the top of the fixed cylinder.

[0008] Preferably, a limiting rod is inserted into the inner wall of the sliding sleeve, and both ends of the limiting rod are fixedly connected to the upper and lower sides of the outer wall of the power unit.

[0009] Preferably, the front and rear sides of the inner wall of the fixed cylinder are fixedly connected with the damper cylinder, and the middle of the inner wall of the damper cylinder is fixedly connected with an inlet and outlet ring.

[0010] Preferably, piston rods are slidably connected to both sides of the inner wall of the damper cylinder, and the outer ends of the piston rods pass through the damper cylinder and are fixedly connected to the front and rear sides of the outer wall of the power unit.

[0011] Preferably, springs are fixedly connected to the outer rings of the piston rod on both sides of the damper cylinder, and the other ends of the springs are fixedly connected to the outer wall of the power unit.

[0012] Preferably, a ferrule is sleeved on the outer wall of the holder, and the top of the ferrule is fixedly connected to the bottom of the muffler, and the muffler is composed of an audio sensor and a frequency jammer.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the utility model, through the structures such as the sliding sleeve, limit rod, damper cylinder, inlet and outlet ring, piston rod and spring in the shock absorbing mechanism, the power unit drives the sliding sleeve to slide left and right on the outer wall of the limit rod, and at the same time the power unit drives the piston rod to slide left and right on the inner wall of the damper cylinder and expand and contract the spring. The piston rod pushes the damping fluid through the inlet and outlet ring to consume kinetic energy, so that the spring cooperates with the damper to reduce the transmission of the vibration of the power unit, thereby realizing the shock absorption of the electric control handle, effectively avoiding the vibration of the power unit from being transmitted to the handle at the same frequency, thereby avoiding hand fatigue and arm soreness caused by long-term use, and improving the comfort and practicality of the device.

[0015] In the utility model, through the structures such as the card seat and the card sleeve in the card connection mechanism, the card sleeve is driven by the muffler to be connected to the card seat, thereby realizing the rapid card connection of the muffler. At the same time, the audio sensor in the muffler is used to detect the waveform of the noise, and the frequency jammer is used to emit sound waves opposite to the noise to offset the noise, thereby realizing auxiliary silencer of the power unit and improving the convenience and practicality of the device.
