Technical Field

[0001] This utility model relates to the field of power tools, specifically to a portable shock-absorbing electric hammer device. Background Technology

[0002] With the rapid development of the construction and decoration industry, electric hammers, as commonly used power tools, are being used more and more frequently. However, traditional electric hammers have obvious drawbacks. They are large in size and weight, making it extremely inconvenient for operators to carry them to different construction sites or to work at heights or in narrow spaces. They also generate violent vibrations during operation, which not only affect the drilling accuracy but also cause hand fatigue for operators. Long-term use may even lead to hand diseases.

[0003] In the prior art, electric hammers are large in size and weight, and are not equipped with a portable device, making them inconvenient to move and carry. Therefore, those skilled in the art provide a portable shock-absorbing electric hammer device to solve the problems mentioned in the background art. Utility Model Content

A load-bearing rope is fixedly installed at the end of each of the two driven shafts facing away from the driven gears. A lifting block is fixedly connected to the end of each of the two load-bearing ropes facing away from the driven shafts.

[0008] As a preferred embodiment of the above technical solution, the protective mechanism includes a protective box that is slidably connected to the surface of the mounting box. Two limiting grooves are symmetrically opened inside the protective box. A locking block is fixedly connected to the center of the side of the protective box facing away from the mounting mechanism.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5 As shown, this utility model provides a technical solution: a portable shock-absorbing electric hammer device, including an electric hammer body 1, an installation mechanism 3 is provided at the bottom of the electric hammer body 1, and a protective mechanism 5 is provided on one side of the installation mechanism 3;

[0025] The mounting mechanism 3 includes a mounting box 31 fixedly mounted on the bottom of the electric hammer body 1. A connecting groove is provided at one end of the top of the mounting box 31, and a buckle 32 is slidably connected in the connecting groove. Two sliding grooves 33 are respectively provided on the opposite side walls of the mounting box 31. A first mounting groove 34 is provided on each of the opposite side walls of the mounting box 31, and the first mounting groove 34 is located above the sliding groove 33.

[0026] In practice, the installation box 31 is made of high-strength aluminum alloy and is formed by precision casting process. While ensuring structural strength, it reduces the overall weight. The buckle 32 is U-shaped, which makes it easy to engage with the buckle block 52, thereby limiting and fixing the protective box 51.

[0027] As one implementation method in this embodiment, please refer to Figures 1-6As shown, lifting blocks 312 are slidably connected in both first mounting slots 34. A sliding groove 35 is provided at the end of the mounting box 31 near the protective mechanism 5. A handle 36 is rotatably connected to the top of the side of the mounting box 31 away from the protective mechanism 5. A second mounting slot 313 is provided in the mounting box 31. A drive shaft 38 is fixedly connected through the second mounting slot 313 at the end of the handle 36 away from the mounting box 31. An elastic rope 37 is fixedly installed on the end of the drive shaft 38 near the handle 36. A drive gear 39 is fixedly sleeved on the end of the drive shaft 38 away from the handle 36. Driven gears 310 are meshed on both sides of the drive gear 39. Driven shafts 311 are fixedly sleeved in both driven gears 310. A load-bearing rope 314 is fixedly installed at the end of both driven shafts 311 away from the driven gears 310. A lifting block 312 is fixedly connected to the end of both load-bearing ropes 314 away from the driven shafts 311.

[0028] In practice, the elastic rope 37 is made of high-strength Kevlar, which has good elastic recovery ability and can better protect the box 51 for stretching and limiting. The handle 36 is ergonomically designed, and the grip part is covered with a soft silicone layer. The sliding groove 33 can cooperate with the slider 55 at the bottom of the protective box 51 to realize the lateral sliding of the protective box 51, which is convenient for storage or unfolding the protective function. By adjusting the length of the load-bearing rope 314, the two lifting blocks 312 can be pulled out and tied together to form a "rope handle" for hand-carrying or shoulder carrying, which is convenient for carrying the electric hammer body 1.

[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the protective mechanism 5 includes a protective box 51 that is slidably connected to the surface of the mounting box 31. Two limiting grooves 53 are symmetrically opened inside the protective box 51. A locking block 52 is fixedly connected to the center of the side of the protective box 51 facing away from the mounting mechanism 3. A protective groove 54 is opened on the top of the protective box 51. Slider blocks 55 are fixedly connected to the bottom of the two inner walls of the protective box 51. The two sliders 55 slide in the two sliding grooves 33 respectively. The mounting box 31 slides on the inner walls of the two limiting grooves 53 respectively.

[0030] In practice, the sliders 55 on both sides of the bottom precisely cooperate with the sliding grooves 33 to provide a smooth sliding experience, while enhancing the friction between the protective box 51 and the mounting box 31, so as to better limit the protective box 51 when the electric hammer is used.

[0031] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the hinge of the mounting box 31 opposite to the protective mechanism 5 is connected to a flip cover 4.

[0032] In practice, the flip cover 4 not only limits the handle 36 but also provides dust protection. A magnetic strip is provided on the edge of the flip cover 4 so that it can be tightly attracted to the mounting box 31 when closed, preventing accidental opening.

[0033] As one implementation method in this embodiment, please refer to Figure 1 As shown, the electric hammer body 1 is fitted with a shock-absorbing rubber sleeve 2.

[0034] In practice, the shock-absorbing rubber sleeve 2 is made of highly elastic and wear-resistant nitrile rubber with an anti-slip textured surface. It can not only effectively buffer the vibration generated during the operation of the electric hammer and reduce operator hand fatigue, but also provide protection when the equipment is accidentally dropped, reducing equipment damage.

[0035] As one implementation method in this embodiment, please refer to Figures 5-6 As shown, both driven shafts 311 rotate on the inner wall of the second mounting groove 313, and the end of the drive shaft 38 away from the handle 36 rotates on the inner wall of the second mounting groove 313.

[0036] Working principle: First, during use, the shock-absorbing rubber sleeve 2 on the electric hammer body 1 can buffer working vibrations and reduce the impact on the hands. When it is necessary to carry it, the slider 55 on the protective box 51 is slidably connected to the sliding groove 33 of the mounting box 31, and the drill bit and other parts are stored in the protective groove 54 on the top of the protective box 51. Then, the flip cover 4 of the mounting box 31 away from the protective mechanism 5 is flipped to expose the handle 36. Next, the handle 36 is rotated to activate the buckle 3 in the connecting groove of the mounting box 31. 2. The protective box 51 is fixed by the extension of the elastic rope 37 and the cooperation of the locking block 52 on the protective box 51. The rotation of the handle 36 drives the drive shaft 38 to rotate. The drive gear 39 on the drive shaft 38 meshes and drives the two driven gears 310 to rotate, which in turn causes the driven shaft 311 to rotate, thus releasing and retracting the load-bearing rope 314, thereby driving the two lifting blocks 312 to move in the first mounting groove 34. By adjusting the length of the load-bearing rope 314, the electric hammer can be carried by the two lifting blocks 312 being tied together.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
