Description

Technical Field

[0001] This utility model relates to the field of lithium hammer technology, specifically a lithium hammer with a buffer mechanism. Background Technology

[0002] A lithium-ion hammer is a power tool that uses a lithium-ion battery as its power source. It generates hammering force through a built-in motor and is used for tasks such as drilling or rock chiseling. Lithium-ion hammers are typically lightweight and easy to use, making them suitable for small-scale tasks. Their two-handed operation control also enhances the stability and safety of their operation.

[0003] An investigation revealed that a Chinese utility model patent discloses a multifunctional lithium-ion electric hammer (publication number: CN208645234U), comprising a shell, a drill bit, a rotating device, and a power unit. This utility model features hammer, hammer drill, and drilling functions, controlled by a knob on the shell. The rotating device includes a striking function, enabling the hammer to function. The power unit controls the left and right movement of a key shaft to engage and disengage the drill bit. It is reliable and easy to install and use.

[0004] In the aforementioned patent, the electric hammer body and the rear handle are an integrated structure. During use, the electric hammer generates a large amount of vibration due to its hammering action. As a result, the frequent hammering under its integrated structure causes the handle to resonate, which in turn generates a certain resonant backward force on the operator, thus reducing the stability of the handheld device and reducing the safety of holding the device.

[0005] Therefore, this utility model provides a lithium-ion hammer with a buffer mechanism to solve the above problems. Utility Model Content

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4 As shown, this utility model provides a lithium-ion hammer with a buffer mechanism, including a hammer body 1, a first rubber spring 11 and a second rubber spring 12 fixedly connected to the rear side of the hammer body 1, and a slot plate 13 fixedly connected to the other end of the first rubber spring 11 and the second rubber spring 12; a handle 2, with two slot plates 21 provided on the side of the handle 2 near the hammer body 1, and the slot plates 21 and the slot plates 13 are interlocked; and a handheld assembly 3, which is disposed on the outer wall of the hammer body 1 and is used for the operator's handheld control. When the handle 2 and the hammer body 1 are installed, the slot plates 21 are first inserted into the inside of the slot plates 13, and then the slot plates 13 are further inserted through the insertion plate 14 to achieve the abutment and limit of the slot plates 21, preventing the slot plates 21 from sliding left and right, thus achieving stable installation of the handle 2. At the same time, the viscoelastic properties of the first rubber spring 11 and the second rubber spring 12 enable them to effectively absorb high-frequency vibration and impact energy, playing a good buffering role, thereby improving the stability of the device when held.

[0029] Furthermore, the slot plate 13 has a T-shaped cross-section, and a connector plate 14 is inserted inside the slot plate 13. The connector plate 14 is used for the contact and limiting of the card plate 21. Through its insertion and installation, the handle 2 can be quickly disassembled and positioned. At the same time, with the insertion of the connector plate 14, the card plate 21 is prevented from shifting left and right, which can achieve auxiliary positioning for the installation of the handle 2 and prevent the card plate 21 from falling off due to vibration during equipment operation, thus further improving the safety of the equipment.

[0030] Furthermore, the handheld component 3 includes a positioning ring 31, which is fixedly connected to the outer wall of the electric hammer body 1. A guide ring 32 is fixedly connected to the outer wall of the positioning ring 31. A hinge seat 33 is rotatably connected inside the positioning ring 31 and the guide ring 32. A handle 35 is fixedly connected to the bottom of the hinge seat 33. A guide shaft 34 passes through the interior of the hinge seat 33 and rotatably abuts against the positioning ring 31 and the guide ring 32. The arrangement of this component allows the operating angle of the handle 35 to be adjusted by left and right rotation, so that the handle 35 can be held by both the left and right hands, thereby improving the adaptability of the device for handheld use.

[0031] Furthermore, the cross-section of the hinge seat 33 is U-shaped, and two limiting grooves adapted to the rotation of the hinge seat 33 are provided on the positioning ring 31 and the guide ring 32. The inner wall of the hinge seat 33 rotates and fits against the outer wall of the guide ring 32. This sliding arrangement plays an auxiliary limiting role for the hinge seat 33, ensuring that the hinge seat 33 can only achieve angular rotation in the left and right directions.

[0032] Furthermore, adjustment holes are provided on both sides of the positioning ring 31 and the guide ring 32, and threaded holes are provided in the middle sections of the positioning ring 31 and the guide ring 32 corresponding to the adjustment holes. The hinge seat 33 is provided with positioning holes that are adapted to the adjustment holes of the positioning ring 31 and the guide ring 32, and threaded rods 36 pass through the positioning holes and adjustment holes and are threadedly connected to the threaded holes. A rubber sleeve is provided on the outer wall of the handle 35. The angle between the adjacent adjustment holes of the positioning ring 31 and the guide ring 32 is 10 degrees. The maximum rotation angle of the handle 35 to both sides in the vertical state is 90 degrees. By opening the position of the adjustment holes, the operating angle of the handle 35 can be further adapted to facilitate its positioning and use at different angles, and meet the safe operation of personnel with different operating habits.

[0033] Working principle: First, assemble the device. First, insert the card plate 21 and the card slot plate 13 into each other. Then, insert the plug plate 14 into the inside of the card slot plate 13 so that the plug plate 14 abuts and limits the card plate 21, ensuring the stability of the handle 2 installation. Then, adjust the tilt angle and tilt direction of the handle 35 according to the usage habits of different workers until the handle 35 is adjusted to a suitable position. Finally, tighten the handle 35 through the threaded rod 36 to complete the tight fixing position, so that the device can be powered on and operated. Due to the setting of the first rubber spring 11 and the second rubber spring 12, their good buffering effect can reduce the resonance generated by the electric hammer body 1 during operation and transmit it to the handle 2, thereby improving the stability of holding the handle 2.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
