Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an electric pick with a buffer function. Background Technology

[0002] An electric hammer is a handheld power tool that uses an electric motor to drive an impact mechanism to generate high-frequency impact force. It is widely used in construction demolition, concrete breaking, and road excavation. Its core structure typically includes a motor, gear transmission system, piston impact assembly, and handle. During operation, the motor drives the piston to reciprocate through the gearbox, converting rotational kinetic energy into axial impact force, which acts on the drill bit or chisel to achieve the function of breaking or drilling hard materials. Because electric hammers need to directly contact high-intensity working surfaces, their design must balance power output and operational stability.

[0003] In existing electric hammers, the reaction force generated by the impact mechanism is transmitted along the tool body towards the handle during operation. Specifically, when the piston assembly strikes the drill bit's tail, in addition to outputting impact energy to the working surface, it also generates a reverse vibration wave due to the reaction force. This vibration wave is transmitted to the handle area through the hammer housing and internal mechanical connections, ultimately acting on the operator's palm and arm. Although some products attempt to mitigate vibration through structures such as rubber shock absorbers and spring dampers, the vibration reduction effect is limited due to the compact mechanical layout and high-frequency impact characteristics. Especially during prolonged or high-intensity operation, a significant amount of vibration energy is still transmitted to the human body, resulting in a significant reduction in operating comfort.

[0004] Continuous high-intensity vibration can cause numbness in the operator's hands, muscle fatigue, and even long-term health problems, severely limiting the tool's continuous service life. The vibration-induced shaking of the tool body can reduce the accuracy of operation, especially when working in fine crushing or confined spaces, which may lead to safety hazards due to unstable operation.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the electric pick, as follows:

[0024] An electric pick with a buffer function, such as Figures 1-3 As shown, the device includes an electric pick 1, a first grip 2, a power cord 201, a second grip 3, a mounting plate 4, a guide rod 5, a spring 6, and a grip assembly. The electric pick 1 is equipped with a power cord 201. A double-layered square mounting plate 4 is connected to the top of the electric pick 1. A guide rod 5 is slidably connected to the upper part of each square mounting plate 4. A spring 6 is fitted onto the top guide rod 5. The top of the upper guide rod 5 is connected to the first grip 2. The top of the upper spring 6 is connected to the first grip 2, and the bottom of the upper spring 6 is connected to the square mounting plate 4. The lower spring 6 is positioned... Between two square mounting plates 4, the power cord 201 is connected to the first grip 2 at its end. The electric hammer 1 also has a double-layered circular mounting plate 4 and guide rods 5 in its middle. Springs 6 are also fitted onto the guide rods 5 in the middle. A second grip 3 is located in the middle of the electric hammer 1. The bottom of the second grip 3 is connected to several guide rods 5. The top of the upper spring 6 in the middle is connected to the second grip 3, and the bottom is connected to the circular mounting plate 4. Both the first grip 2 and the second grip 3 are equipped with handles, which have grip components for shock absorption. Impact force drives the guide rods 5 to slide along the mounting plate 4. The lower spring 6 is compressed first, followed by deformation of the upper spring 6. The lower spring 6 has lower stiffness and prioritizes compression to filter high-frequency vibrations; the upper spring 6 has higher stiffness and further absorbs low- and medium-frequency impact energy. This two-stage buffering reduces the instantaneous impact peak by more than 80%.

[0025] like Figures 2-4 As shown, the grip assembly includes an airbag 7, a mounting ring 8, and an air valve 9. The first grip frame 2 and the second grip frame 3 are both fitted with airbags 7. The first grip frame 2 and the second grip frame 3 are both connected to mounting rings 8 for stabilizing the airbag 7. The mounting rings 8 are fitted at both ends of the airbag 7. The airbag 7 is equipped with an air valve 9. When the operator grips, the airbag 7 is locally indented due to grip pressure, and the internal air pressure increases. When the impact is transmitted to the grip, the airbag 7 expands through gas flow and elastic deformation, and the air pressure dynamically balances and disperses the grip pressure, reducing the pressure at the hand contact point. The airbag buffers the vibration energy transmitted to the hand by 40%-50%.

[0026] like Figure 4 As shown, it also includes a rubber ring 10. The side of the mounting ring 8 that contacts the airbag 7 is connected to the rubber ring 10. The rubber ring 10 is slightly offset laterally due to the deformation and compression of the airbag 7. The anti-slip sleeve 14 prevents the tool from slipping out of the hand. The rubber ring 10 reduces the frictional wear between the airbag 7 and the mounting ring 8 and extends the service life.

[0027] like Figure 3 As shown, it also includes a pull rope 11. One end of the pull rope 11 is connected to the air valve 9, and the other end is connected to the grip frame. When the air valve 9 is disassembled, the pull rope 11 restricts its displacement range and prevents the air valve 9 from being lost, thus improving the ease of operation.

[0028] like Figure 1 As shown, it also includes a lighting lamp 12. Lighting lamps 12 are connected to both the front and rear sides of the electric pick 1. During operation, the lighting lamps 12 are continuously lit, and the light is focused on the working surface of the pick head. The lighting lamps 12 provide a shadowless light source to ensure the accuracy of operation in narrow spaces.

[0029] like Figure 1 As shown, it also includes a buckle 13. The square mounting plate 4 has a buckle 13 connected to its side. The power cord 201 is engaged with the buckle 13. After the power cord 201 is wound up, it is fixed by the buckle 13. The buckle 13 keeps the power cord 201 in place and avoids the risk of tangling.

[0030] like Figure 2 As shown, it also includes an anti-slip sleeve 14. The airbag 7 is fitted with an anti-slip sleeve 14. The anti-slip sleeve 14 undergoes slight deformation with the gripping force, increasing the coefficient of friction.

[0031] like Figure 1 As shown, it also includes a telescopic pad 15, which wraps around the guide rod 5 and the spring 6. Its upper and lower ends are respectively connected to the bottom surfaces of the mounting plate 4, the first gripping frame 2, and the second gripping frame 3, completely sealing the gaps between the mounting plates 4 and between the mounting plates and the gripping frames. One end of the telescopic pad 15 is connected to the mounting plate 4, and the other end is connected to the bottom surfaces of the first gripping frame 2 and the second gripping frame 3. When the spring 6 is compressed, the telescopic pad 15 folds and contracts synchronously; when the spring 6 returns to its original position, the telescopic pad 15 extends to fill the gaps in the mounting plate 4, completely sealing the movement space between the guide rod 5 and the spring 6, preventing dust intrusion, and avoiding mechanical jamming.

[0032] Before operation, connect the power cord 201 to the power supply, then connect the air pump to the air valve 9 of the first grip 2 and the second grip 3, inflating the airbag 7 to the preset pressure, ensuring that the hardness of the airbag 7 is suitable for the current working intensity. After inflation, disconnect the air pump, and secure the power cord 201 by winding it several times and securing it with the clip 13 to prevent the cable from dragging and interfering with the operation. At the same time, check whether the telescopic pad 15 completely seals the gap of the mounting plate 4, and confirm that the guide rod 5 and the spring 6 slide without obstruction. After gripping the anti-slip sleeve 14, press the start / stop button on the first grip 2 to start the electric hammer 1. The side lights 12 will automatically turn on, providing shadowless lighting for the working surface.

[0033] After the electric pick 1 is started, the operator holds the anti-slip sleeves 14 of the first and second grips 3 with both hands, aligns the pick head with the target to be broken, and applies pressure. When the pick head impacts the working surface, the reaction force is transmitted through the main body of the electric pick 1 to the double-layer mounting plate 4. The lower spring 6 compresses first to absorb high-frequency vibrations, and then the upper spring 6 further deforms to disperse the medium and low-frequency impact energy. When the remaining vibration is transmitted to the grips, the airbag 7 forms dynamic damping through gas compression and flow, evenly distributing the hand pressure. During the process, the telescopic pad 15 expands and contracts synchronously with the compression of the spring 6, always sealing the mechanical gaps to prevent dust intrusion; the lighting 12 continuously focuses on the working area to ensure operational accuracy.

[0034] After completing the crushing operation, release the start / stop button to turn off the electric pick 1, press the air valve 9 to release the gas in the air bag 7. After the air bag 7 contracts, the air valve 9 is suspended by the pull rope 11 to prevent loss. Then unplug the power cord 201, wind it neatly, and use the clip 13 to secure the end of the cable to prevent tangling. Check whether the guide rod 5 and spring 6 are reset, and whether the telescopic pad 15 has returned to its initial sealing state to ensure that there is no mechanical interference before the next use. If continuous operation is required, the air bag 7 can be kept inflated, and only the power cord 201 needs to be stored and the debris attached to the pick head needs to be cleaned.
