Description

A low-vibration grip electric pick Technical Field

[0001] This utility model relates to the field of handle electric pick technology, specifically a low-vibration handle electric pick. Background Technology

[0002] A handle-operated electric pick is a handheld power tool primarily used for breaking and chiseling hard materials such as concrete and brick. Its structure revolves around the handle as the core of its operation, coupled with a motor-driven piston impact mechanism. The handle transmits operating force and controls the tool's direction. The handle design emphasizes ergonomics and typically uses non-slip materials to enhance grip stability. The comfort of the handle and the tool's impact efficiency directly affect the working experience, making it a commonly used piece of equipment in fields such as municipal engineering and home renovation repair.

[0003] Currently, low-vibration-sensor handle electric hammers on the market generally use a fixed installation method for the rubber anti-slip material on the handle. With long-term, high-frequency use by users, the rubber material inevitably wears down, causing the surface texture to become shallower, the coefficient of friction to decrease, and the anti-slip performance to be significantly reduced. Even more problematic is that this anti-slip rubber material is often integrated with the handle body and cannot be removed and replaced separately. Once the wear is severe, the entire electric hammer handle or even the entire hammer must be replaced. This not only increases the cost of use but also reduces hand stability during operation, greatly increasing the risk of slipping and seriously threatening the personal safety of workers, and severely limiting the durability and safety of the tool. Therefore, we propose a low-vibration-sensor handle electric hammer. Summary of the Invention

[0004] The purpose of this invention is to provide a low-vibration-sensitivity electric pick with a handle to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A low-vibration-sensing electric pick includes a low-vibration-sensing electric pick body and a handle fixedly installed at the bottom of the low-vibration-sensing electric pick body. The outer surface of the handle is provided with a vibration damping mechanism to reduce vibration during use. Reinforcing mechanisms are provided at both ends of the vibration damping mechanism. Four limiting grooves for limiting the movement are opened on the outer circumference of the handle. A control switch is also fixedly installed on the outside of the handle.

[0007] Preferably, the vibration damping mechanism includes a vibration damping rubber sleeve, the inner surface of which is movably sleeved on the outside of the handle, and four limiting rubber strips that cooperate with four limiting grooves are fixedly connected to the inner wall of the vibration damping rubber sleeve, the outer surface of which is movably engaged in the inner cavity of the limiting groove.

[0008] Preferably, the top sidewall of the vibration-damping rubber sleeve has a hole, the external movable sleeve of the control switch is fitted into the hole, the outer wall of the vibration-damping rubber sleeve has multiple drainage grooves for sweat drainage, and the outer wall of the vibration-damping rubber sleeve also has four annular grooves, and the hole, drainage grooves and annular grooves are connected to each other.

[0009] Preferably, the reinforcement mechanism includes an elastic metal hoop that is movably fitted into the annular groove at the end of the vibration-damping rubber sleeve. One end of the elastic metal hoop has a first threaded hole for fastening the elastic metal hoop, and the other end of the elastic metal hoop has a second threaded hole for fastening the elastic metal hoop.

[0010] Preferably, the inner cavities of the first threaded hole and the second threaded hole are threadedly connected to a threaded post, and the threaded end of the threaded post is threadedly connected to a nut.

[0011] Preferably, both the vibration damping rubber sleeve and the limiting rubber strip are made of neoprene rubber, and the vibration damping rubber sleeve also has multiple stainless steel sheets embedded inside to dissipate vibration energy.

[0012] Preferably, a mounting block is fixedly connected to one side wall of the low-vibration grip electric pick body, and a dual-head air pump is fixedly installed on the side wall of the mounting block away from the low-vibration grip electric pick body. A first connecting pipe is fixedly sleeved on one air outlet end of the dual-head air pump, and a first annular jet head is fixedly sleeved on the end of the first connecting pipe away from the dual-head air pump. The outer inner ring of the first annular jet head is fixedly sleeved on the output end of the low-vibration grip electric pick body. A second connecting pipe is fixedly sleeved on the other air outlet end of the dual-head air pump, and a second annular jet head is fixedly sleeved on the end of the second connecting pipe away from the dual-head air pump. The outer inner ring of the second annular jet head is fixedly sleeved on the top of the handle.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a vibration-damping rubber sleeve and elastic metal hoops, involves fitting the vibration-damping rubber sleeve onto the handle, and fitting two elastic metal hoops into the annular grooves at both ends of the vibration-damping rubber sleeve. By rotating the threaded post into the first and second threaded holes, and then fitting the nut from the threaded end of the threaded post, the ends of the elastic metal hoops are compressed by rotating the nut, thereby reinforcing the vibration-damping rubber sleeve. When the vibration-damping rubber sleeve needs to be replaced, the nut and threaded post are removed by using a tool to rotate in the opposite direction, and the elastic metal hoops can be removed, thus removing the vibration-damping rubber sleeve for replacement. This prevents a decrease in hand grip stability and helps protect the personal safety of workers.

[0015] 2. This utility model utilizes a stainless steel sheet. Neoprene rubber is adept at absorbing high-frequency vibrations generated during electric hammer operation, while also possessing weather resistance and flame retardancy, making it suitable for long-term gripping. By embedding a stainless steel sheet inside the vibration-damping rubber sleeve, the difference in modulus between the stainless steel sheet and the vibration-damping rubber sleeve during vibration induces interfacial friction damping, which helps to further dissipate vibration energy at the grip and improve user comfort.

[0016] 3. This utility model features a dual-head air pump. Upon activation, the first outlet of the dual-head air pump transmits gas to the first annular jet head via a first connecting pipe. This gas is then blown onto the output head of the low-vibration handle electric pick. The blowing accelerates airflow, carrying away heat and preventing damage from overheating, thus extending its lifespan. Simultaneously, the blowing effectively removes dust and debris generated during crushing and excavation operations, keeping the head of the low-vibration handle electric pick clean and preventing damage. The second outlet of the dual-head air pump transmits gas to the second annular jet head via a second connecting pipe. This second jet head blows out gas, accelerating the drying of sweat from the vibration-damping rubber sleeve. Simultaneously, the airflow directed towards the worker's hands, improving comfort during use. Attached Figure Description

[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in Figures 1-4, a low-vibration-sensitivity electric pick includes a low-vibration-sensitivity electric pick body 1 and a handle 2 fixedly installed at the bottom of the low-vibration-sensitivity electric pick body 1. The outer surface of the handle 2 is provided with a vibration damping mechanism 4 to reduce vibration during use. Reinforcing mechanisms 5 are provided at both ends of the vibration damping mechanism 4. Four limiting grooves 3 for limiting movement are formed on the outer circumference of the handle 2. A control switch 6 is also fixedly installed on the outside of the handle 2. The vibration damping mechanism 4 includes a vibration damping rubber sleeve 41, the inner surface of which is movably sleeved on the handle 2. Externally, the inner wall of the vibration damping rubber sleeve 41 is fixedly connected with four limiting rubber strips 43 that cooperate with four limiting grooves 3. The external of the limiting rubber strips 43 is movably engaged in the inner cavity of the limiting grooves 3. A hole 42 is opened at the top side wall of the vibration damping rubber sleeve 41. The external of the control switch 6 is movably engaged in the hole 42. Multiple guide grooves 44 for sweat drainage are opened on the outer wall of the vibration damping rubber sleeve 41. Four annular grooves 45 are also opened on the outer wall of the vibration damping rubber sleeve 41. The hole 42, guide grooves 44 and annular grooves 45 are connected to each other.

[0025] In practice, the vibration-damping rubber sleeve 41 is fitted onto the handle 2, and the control switch 6 is exposed through the hole 42. The control switch 6 is used to control the operation of the low-vibration handle electric pick body 1. By locking the limiting rubber strip 43 into the limiting groove 3, the vibration-damping rubber sleeve 41 can be prevented from shifting laterally during use. By using the two annular grooves 45 and multiple guide grooves 44 on the middle of the vibration-damping rubber sleeve 41, the friction between the worker's hand and the vibration-damping rubber sleeve 41 can be increased, reducing the possibility of the worker's hand slipping off during use. At the same time, the multiple guide grooves 44 can be used to guide the sweat from the worker's hands, enhancing the practicality of the device.

[0026] As a technical optimization of this utility model, the reinforcement mechanism 5 includes an elastic metal hoop 51 that is movably sleeved in the annular groove 45 at the end of the vibration damping rubber sleeve 41. One end of the elastic metal hoop 51 is provided with a first threaded hole 52 for fastening the elastic metal hoop 51, and the other end of the elastic metal hoop 51 is provided with a second threaded hole 53 for fastening the elastic metal hoop 51. The inner cavities of the first threaded hole 52 and the second threaded hole 53 are threadedly connected to a threaded post 54, and the threaded end of the threaded post 54 is threadedly connected to a nut 55.

[0027] In practice, by fitting two elastic metal clamps 51 into the annular grooves 45 at both ends of the vibration-damping rubber sleeve 41, by rotating the threaded post 54 into the first threaded hole 52 and the second threaded hole 53, and then fitting the nut 55 from the threaded end of the threaded post 54, the elastic metal clamps 51 can be tightened by rotating the nut 55 to compress the two ends of the elastic metal clamps 51, thereby reinforcing the vibration-damping rubber sleeve 41 and preventing the vibration-damping rubber sleeve 41 from shifting and affecting the work when the low-vibration grip electric pick body 1 is used.

[0028] As a technical optimization of this utility model, both the vibration damping rubber sleeve 41 and the limiting rubber strip 43 are made of neoprene rubber, and the inside of the vibration damping rubber sleeve 41 is also embedded with multiple stainless steel sheets for dissipating vibration energy.

[0029] In practice, neoprene rubber is good at absorbing the high-frequency vibrations generated during electric hammer operation. It also has weather resistance and flame retardancy, making it suitable for long-term use. By embedding a stainless steel sheet inside the vibration damping rubber sleeve 41, when the vibration damping rubber sleeve 41 vibrates, the difference in modulus between the stainless steel sheet and the vibration damping rubber sleeve 41 causes interfacial friction damping, which helps to further dissipate the vibration energy at the handle and improve the user's comfort.

[0030] As a technical optimization of this utility model, a mounting block 7 is fixedly connected to one side wall of the low-vibration grip electric pick body 1. A dual-head air pump 8 is fixedly installed on the side wall of the mounting block 7 away from the low-vibration grip electric pick body 1. A first connecting pipe 9 is fixedly sleeved on one air outlet end of the dual-head air pump 8. A first annular jet head 10 is fixedly sleeved on the end of the first connecting pipe 9 away from the dual-head air pump 8. The inner ring of the first annular jet head 10 is fixedly sleeved on the outer side of the outer ring of the first annular jet head 10 and fixedly sleeved on the output end of the low-vibration grip electric pick body 1. A second connecting pipe 11 is fixedly sleeved on the other air outlet end of the dual-head air pump 8. A second annular jet head 12 is fixedly sleeved on the end of the second connecting pipe 11 away from the dual-head air pump 8 and fixedly sleeved on the top of the handle 2.

[0031] In specific implementation, by starting the dual-head air pump 8, the first air outlet of the dual-head air pump 8 transmits gas to the first annular jet head 10 through the first connecting pipe 9. The gas is blown by the first annular jet head 10 towards the output head of the low-vibration grip electric pick body 1. The blowing can accelerate the airflow, remove heat, prevent the low-vibration grip electric pick body 1 from being damaged due to overheating, and extend its service life. At the same time, the blowing can promptly remove a large amount of dust and debris generated by the low-vibration grip electric pick body 1 during crushing, digging and other operations, keep the head of the low-vibration grip electric pick body 1 clean, and prevent the low-vibration grip electric pick body 1 from being damaged.

[0032] The second air outlet of the dual-head air pump 8 transmits gas to the second annular jet head 12 through the second connecting pipe 11. The gas is blown out through the second annular jet head 12, which can accelerate the expulsion and drying of sweat on the vibration damping rubber sleeve 41. At the same time, the airflow blows towards the worker's hands, which can improve the worker's comfort.

[0033] In use, this utility model involves fitting a vibration-damping rubber sleeve 41 onto the handle 2, allowing the control switch 6 to protrude through the hole 42, and securing a limiting rubber strip 43 within a limiting groove 3 to prevent lateral displacement of the vibration-damping rubber sleeve 41. Two annular grooves 45 and multiple drainage grooves 44 on the middle of the vibration-damping rubber sleeve 41 increase the friction between the user's hand and the sleeve, reducing the likelihood of the hand slipping off. The drainage grooves 44 also guide sweat from the user's hands. Two elastic metal clamps 51 are fitted into the annular grooves 45 at both ends of the vibration-damping rubber sleeve 41. A threaded post 54 is inserted into the first threaded hole 52 and the second threaded hole 53, and a nut 55 is fitted from the threaded end of the post 54. Rotating the nut 55 compresses the ends of the elastic metal clamps 51, tightening them and reinforcing the vibration-damping rubber sleeve 41. The control switch 6 controls the operation of the low-vibration handle electric pick body 1. The dual-head air pump 8 is activated. The first outlet of the dual-head air pump 8 transmits gas to the first annular jet head 10 via the first connecting pipe 9. The gas is then blown through the first annular jet head 10 towards the output head of the low-vibration handle electric pick 1. This airflow accelerates air circulation, carrying away heat and preventing damage to the low-vibration handle electric pick 1 due to overheating. Simultaneously, the airflow effectively removes the large amount of dust and debris generated during crushing and excavation operations, keeping the head of the low-vibration handle electric pick 1 clean. The second air outlet transmits gas to the second annular jet head 12 through the second connecting pipe 11. The second annular jet head 12 blows out the gas, which accelerates the removal and drying of sweat on the vibration damping rubber sleeve 41. At the same time, the airflow blows towards the worker's hands, improving the worker's comfort. When the vibration damping rubber sleeve 41 needs to be replaced, the nut 55 is turned in the opposite direction using a tool to remove the nut 55 and the threaded post 54, and the elastic metal clamp 51 can be removed, thereby removing the vibration damping rubber sleeve 41 for replacement.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
