Description

Technical Field

[0001] This utility model relates to the field of dustproof and shock-absorbing electric hammers, and in particular to a dustproof and shock-absorbing structure for electric hammers. Background Technology

[0002] The dustproof and impact-absorbing structure of this electric hammer is mainly used for drilling operations in scenarios such as building construction, interior decoration, and equipment installation. It can prevent dust from spreading to the surroundings when the electric hammer is drilling at high speed, reducing the risk of operators inhaling dust. At the same time, the buffer component absorbs some of the impact energy, reduces the transmission of vibration to the operator's hands, protects the wrists and arms, and also reduces the wear of the electric hammer's internal parts, extending the service life of the equipment and adapting to the working needs of hard materials such as concrete and brick.

[0003] To address the structural improvements, existing technologies have optimized the edge shape of the dust cover by replacing the straight edge with an arc-shaped fitting design to enhance the seal with the working surface. At the same time, the spring parameters of the buffer mechanism have been improved by using variable-diameter springs instead of constant-diameter springs to enhance the buffering effect. Additionally, the connection buckle structure between the dust cover and the electric hammer body has been adjusted to increase the number of buckles and the engagement depth to enhance connection stability.

[0004] The main defects of this structure are the insufficient design of the connection and compatibility between the dust cover and the electric hammer. Conventional dust covers are mostly fixed to the electric hammer with simple buckles or bolts. When the electric hammer vibrates at high speed, the connection is prone to loosening, causing gaps to appear between the dust cover and the working surface. Dust spreads from the gaps and loses its dust protection function. At the same time, the disassembly process of its connection structure is cumbersome. When the working environment is a confined space or when dust protection is not required, it is difficult to quickly remove the dust cover. It cannot adapt to diverse working needs and has low applicability. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a dustproof and shock-absorbing structure for an electric hammer, aiming to solve the problem in the prior art that the connection is easily loosened when the electric hammer vibrates at high speed, causing gaps to appear between the dust cover and the working surface, allowing dust to spread from the gaps and losing its dustproof function.

[0019] Reference Figures 1-3The present invention provides an embodiment of a dustproof and impact-absorbing structure for an electric hammer. This structure achieves dustproofing and impact buffering during the use of the electric hammer 1 through a shockproof and dustproof mechanism 2 and a disassembly and assembly mechanism 3. The electric hammer 1 is the main working component of the structure. The top of the electric hammer 1 is equipped with the shockproof and dustproof mechanism 2 and the disassembly and assembly mechanism 3. The shockproof and dustproof mechanism 2 reduces the impact of the electric hammer 1 during operation and blocks dust. The disassembly and assembly mechanism 3 is used for the quick installation and removal of the dustproof components. The shockproof and dustproof mechanism 2 includes a connecting shell 211, which is the basic component of the shockproof and dustproof mechanism 2. The inner wall of the connecting shell 211 is fixedly connected to the outer wall of the electric hammer 1. The connecting shell 211 is fixed to the electric hammer 1 to install other dustproof components. The vibration component has a slider groove 212 on the inner wall of the connecting housing 211, which provides a sliding path for the elongated locking block 215. A telescopic ring 213 is slidably connected to the connecting housing 211, and the telescopic ring 213 can slide along the inner wall of the connecting housing 211 to adjust its position. The elongated locking block 215 is fixedly connected to the outer wall of the telescopic ring 213, and the elongated locking block 215 slides synchronously with the telescopic ring 213. The outer wall of the elongated locking block 215 is slidably connected to the inner wall of the slider groove 212, and the elongated locking block 215 slides along the slider groove 212 to guide the movement of the telescopic ring 213. The outer wall of the telescopic ring 213 is elastically connected to the inner wall of the connecting housing 211 through a shock-absorbing spring 214, which provides buffering force for the telescopic ring 213 to reduce impact.

[0020] Reference Figures 3-5 The disassembly and assembly mechanism 3 includes a locking block groove 311, which provides sliding space for the automatic locking block 313. The locking block groove 311 is located on the inner wall of the telescopic ring 213, and its position is adapted to the movement of the automatic locking block 313. The disassembly and assembly mechanism 3 also includes a friction block 312, which increases the resistance when the automatic locking block 313 slides. The outer wall of the friction block 312 is fixedly connected to the inner wall of the locking block groove 311, and the friction block 312 is fixed in the locking block groove 311 to exert friction, facilitating disassembly and assembly. The assembly mechanism 3 also includes an automatic locking block 313, which locks and unlocks the components by sliding. The outer wall of the automatic locking block 313 is slidably connected to the inner wall of the locking block groove 311. The automatic locking block 313 can slide along the inner wall of the locking block groove 311 for easy assembly and disassembly. The assembly mechanism 3 also includes a locking block connecting block 317, which is used to connect the automatic locking block 313 and the extending barrel block 216. The outer wall of the locking block connecting block 317 is fixedly connected to the outer wall of the automatic locking block 313, and the locking block connecting block 317 moves synchronously with the automatic locking block 313.

[0021] Reference Figure 3The disassembly and assembly mechanism 3 also includes an extension block 216, which connects the locking block connecting block 317 and the dust cover 217. The outer wall of the extension block 216 is fixedly connected to the outer wall of the locking block connecting block 317. The extension block 216 moves synchronously with the locking block connecting block 317. The end of the extension block 216 away from the locking block connecting block 317 is fixedly connected to the dust cover 217, which moves synchronously with the extension block 216 to prevent dust. The disassembly and assembly mechanism 3 also includes a friction groove 314, which cooperates with the friction stop block 312 to increase friction. The friction groove 314 is formed on the outer wall of the automatic locking block 313. The friction groove 314 is positioned corresponding to the friction block 312. The inner wall of the friction groove 314 is slidably connected to the outer wall of the friction block 312. The friction block 312 slides along the friction groove 314 to increase resistance. The disassembly and assembly mechanism 3 also includes a guide rod 315. The guide rod 315 provides sliding guidance for the automatic locking block 313. The outer wall of the guide rod 315 is fixedly connected to the inner wall of the inserted barrel block 216. The guide rod 315 is fixed inside the inserted barrel block 216 to ensure stable guidance. The outer wall of the inserted barrel block 216 is elastically connected to the outer wall of the automatic locking block 313 through a locking spring 316. The locking spring 316 provides a reset spring force for the automatic locking block 313.

[0022] Working principle: When the electric hammer 1 is started, the dustproof and shock-absorbing impact structure takes the electric hammer 1 as the main body, and the dust cover 217 of the shockproof and dustproof mechanism 2 expands and contracts with the impact to buffer, and is sealed with the help of the shock-absorbing spring 214; the easy disassembly and assembly mechanism 3 slides through the automatic locking block 313 to realize the quick installation and removal of the dust cover 217, which is suitable for different working scenarios.

[0023] When the electric hammer 1 generates impact vibration during operation, the connecting shell 211 vibrates synchronously with the electric hammer 1. The slider groove 212 on its inner wall guides the long locking block 215 to slide. The telescopic ring 213, which is fixed to the long locking block 215, slides along the inner wall of the connecting shell 211. The shock-absorbing spring 214 between the telescopic ring 213 and the connecting shell 211 is compressed or stretched as it slides, absorbing the impact energy. The insertion block 216 at the other end of the telescopic ring 213 moves synchronously, causing the dust cover 217 to adjust its extension and retraction depth according to the impact, always keeping it close to the working surface, blocking the spread of dust, and buffering the impact on the electric hammer 1 and the operator.

[0024] When disassembling and assembling the dust cover 217, operate the automatic locking block 313. During disassembly, press the automatic locking block 313, which slides along the guide rod 315 in the locking block groove 311, compressing the locking block spring 316. The friction groove 314 on the outer wall of the automatic locking block 313 slides with the friction resistance block 312 in the locking block groove 311, providing resistance feedback. The automatic locking block 313 drives the extended barrel block 216 to disengage from the lock through the locking block connecting block 317. During installation, push the extended barrel block 216 in the opposite direction, and the automatic locking block 313 resets and latches under the elastic force of the locking block spring 316, realizing the quick assembly and disassembly of the dust cover 217, which is suitable for various operating scenarios.
