Description

Technical Field

[0001] This utility model relates to the field of electric hammer design, and in particular to the structure of a lithium-ion heavy-duty electric hammer handle with shock absorption function. Background Technology

[0002] A hammer drill is an electrically powered rotary hammer drill with a safety clutch and a pneumatic hammering mechanism. It works by using a piston to compress gas and impact the drill bit, requiring minimal manual force. It can drill holes 6-100mm deep in hard materials such as concrete, brick, and stone. Hammer drills are highly efficient at drilling in these materials, but they cannot drill holes in metal.

[0003] The lithium-ion heavy-duty electric hammer contains an electric motor that drives a crankshaft connecting rod mechanism, converting the motor's rotational motion into the reciprocating motion of a piston. The piston generates air pressure changes within the cylinder, pushing the impact piston to reciprocate, thus generating impact force. Simultaneously, the drill bit is subjected to impact force while rotating, achieving efficient drilling and hammering operations.

[0004] The connection between the handle and the body is a key point for vibration transmission. However, some products only have soft rubber wrapped around the outer layer of the handle, and the vibration is transmitted directly through the metal parts. The soft rubber can only alleviate surface vibration. In addition, the handles of many heavy-duty lithium-ion hammer drills are fixed and the angle cannot be adjusted, making it difficult for workers to find a comfortable grip, increasing the difficulty of operation and affecting work efficiency.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] First Embodiment

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of the lithium-ion heavy-duty electric hammer handle structure with shock absorption function provided by this utility model; Figure 2 for Figure 1 The diagram shows the front side structure. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. The structure of the lithium-ion heavy-duty electric hammer handle with shock absorption function includes: a main body mechanism 1, the main body mechanism 1 including a protective shell 11, a rotating fixing mechanism 2 provided on the surface of the protective shell 11, the rotating fixing mechanism 2 including a toothed pressure plate 23, the toothed pressure plate 23 being installed on the outer surface of the protective shell 11;

[0032] The reset extrusion mechanism 3 includes a secondary handle 31, which is connected to the bottom of the rotating sleeve 22.

[0033] The shock absorption mechanism 4 includes a spring telescopic plate 41, which is connected to the bottom of the auxiliary handle 31.

[0034] The vertical fixing mechanism 5 includes a fixing block 51, which is installed inside the secondary handle 31.

[0035] The protective shell 11 houses a motor. The rotating fixing mechanism 2 rotates and connects to fix the secondary handle 31 at different angles. The toothed pressure plate 23 is composed of two teeth arranged in an array on the inner surface of an arc-shaped plate. The reset pressing mechanism 3 facilitates handholding while simultaneously resetting and engaging the toothed pressure plate 23 via a connecting transmission. The secondary handle 31 is cylindrical, with its outer surface covered with anti-slip and shock-absorbing material to prevent hand slippage and reduce vibration. The shock-absorbing mechanism 4 reduces shock and improves handhold stability. The spring telescopic plate 41 consists of two telescopic rods. The internal components consist of two springs, one end of which is rotatably connected to the two ends of the bottom of the auxiliary handle 31. The vertical fixing mechanism 5 is used to fix the spring telescopic plate 41. There are two fixing blocks 51, which are slidably connected to the left and right surfaces of the front end of the auxiliary handle 31, and the end of the fixing block 51 embedded in the auxiliary handle 31 is inclined. A hole is opened on the inner surface of the connection between the two spring telescopic plates 41 and the auxiliary handle 31. When the spring telescopic plate 41 is rotated to the vertical state, the two fixing blocks 51 can be embedded in the two holes respectively, thus fixing the two spring telescopic plates 41.

[0036] A lithium battery 12 is connected to the bottom of the protective shell 11, a drill bit 13 is installed at the front end of the protective shell 11, and a handle 14 is connected to the rear end of the protective shell 11.

[0037] The protective shell 11 houses a motor, the drill bit 13 is connected to the motor shaft, the lithium battery 12 is connected to the motor via a circuit, and a button is installed on the outer surface. By pressing the button, the lithium battery 12 is connected to the motor, and the motor drives the drill bit 13 to rotate at high speed to achieve drilling.

[0038] The outer surface of the protective shell 11 near the front end is connected to a toothed ring 21, and the outer surface of the protective shell 11 near the front end is connected to a rotating sleeve 22. The toothed pressure plate 23 is movably connected to both ends of the rotating sleeve 22.

[0039] The toothed ring 21 is ring-shaped and has teeth arranged on its outer surface. The rotating sleeve 22 is fitted on the outer surface of the connection between the protective shell 11 and the toothed ring 21. The two toothed pressure plates 23 are slidably connected to the two ends of the rotating sleeve 22. The rotating sleeve 22 is fixed by meshing with the surface of the toothed ring 21 through the two rotating sleeves 22.

[0040] The secondary handle 31 is connected to the bottom of the rotating sleeve 22. An elastic element 32 is connected inside the secondary handle 31. A connecting element 33 is connected to the surface of the toothed pressure plate 23. The connecting element 33 is connected to the surface of the elastic element 32.

[0041] The elastic element 32 can be composed of a bidirectional spring telescopic rod and a slide rod with a spring connected to its surface, preferably the latter. The bottom of the connecting element 33 is slidably connected to the surface of the slide rod through the surface of the auxiliary handle 31, and the two ends of the spring are respectively fixedly connected to the bottom of the two toothed pressure plates 23. Under the action of the spring force, the two connecting elements 33 are given an outward pushing force, thereby disengaging the two pressing plates 34 from the engagement of the auxiliary handle 31. At this time, the auxiliary handle 31 can be rotated.

[0042] The bottom of the connector 33 is connected to a compression plate 34, and one end of the spring telescopic plate 41 is connected to a damping plate 42. The surface of the damping plate 42 is provided with a fixing groove 43.

[0043] There are two pressing plates 34, which are fixedly connected to the bottom of the two connecting parts 33 and movably installed on the outer surface of the auxiliary handle 31. By pressing the two pressing plates 34, the two connecting parts 33 drive the two toothed pressing plates 23 to move inward and engage with the surface of the toothed ring 21, thereby fixing the angle of the auxiliary handle 31. There are two damping plates 42, which are fixedly connected to the front end of the two spring telescopic plates 41. Each of the two damping plates 42 has a fixing groove 43. When not in use, the two spring telescopic plates 41 can be rotated to a vertical state. At this time, the bottom of the two connecting parts 33 is embedded in the inside of the fixing groove 43, thus fixing the spring telescopic plates 41.

[0044] A threaded rod 52 is connected to the surface of the lithium battery 12, and a push block 53 is connected to the bottom of the threaded rod 52. The push block 53 is connected to the surface of the fixed block 51.

[0045] The front end of the bottom of the lithium battery 12 is connected to a square groove. Two fixed blocks 51 are slidably connected to the left and right ends of the square box, respectively. The bottom of both ends of the push block 53 is inclined. Rotating the threaded rod 52 can drive the push block 53 to move downward, so that the two inclined surfaces are connected to the inclined surfaces of one end of the two fixed blocks 51, giving the two fixed blocks 51 an outward pushing force, thereby pushing the fixed blocks 51 into the interior of the two spring telescopic plates 41, and realizing the fixation of the spring telescopic plates 41.

[0046] The working principle of the shock-absorbing lithium-ion heavy-duty electric hammer handle structure provided by this utility model is as follows:

[0047] Before starting work, rotate the spring telescopic plate 41 to a perpendicular position with the auxiliary handle 31. Then, rotate the threaded rod 52 to move the pushing block 53 downward, pushing the two fixed blocks 51 outward to slide into the interior of the two spring telescopic plates 41, fixing the spring telescopic plates 41. Then, hold the auxiliary handle 31 with one hand and the handle 14 with the other hand to connect the damping plate 42 to the wall. Then, rotate the auxiliary handle 31 to drive the rotating sleeve 22 to rotate on the surface of the protective shell 11. After rotating to a suitable angle, press the two pressing plates 34 and connect them through the connector 33. The two toothed pressure plates 23 are driven to face each other and mesh with the toothed ring 21. Through the meshing of the toothed ring 21 and the toothed pressure plate 23, the rotating sleeve 22 is fixed on the outer surface of the protective shell 11. Then, the motor is started to drive the drill bit 13 to rotate at high speed and generate vibration force, which is transmitted to the surface of the auxiliary handle 31 through the protective shell 11. During this process, the movement of the drill bit 13 causes the spring telescopic plate 41 to extend and retract, absorbing the vibration force. The damping plate 42 dampens the vibration force and converts it into heat energy, reducing the vibration of the main mechanism 1 and the surface of the auxiliary handle 31.

[0048] Compared with related technologies, the lithium-ion heavy-duty electric hammer handle structure with shock absorption function provided by this utility model has the following beneficial effects:

[0049] This utility model provides a lithium-ion heavy-duty electric hammer handle structure with shock absorption function. The shock absorption mechanism 4 is fixed and connected to the wall by the vertical fixing mechanism 5. During operation, it can extend and retract to reduce the vibration of the auxiliary handle 31. At the same time, by pressing and resetting the squeezing mechanism 3, the toothed pressure plate 23 can be moved to fix the auxiliary handle 31 at different angles, thus facilitating operation by the staff in different postures.

[0053] The sealing cover 61 is cylindrical, with threads on the inner surface of one end, and threads on the outer surface of the protective shell 11 near the front end. The sealing cover 61 is threaded to the outer surface of the protective shell 11, thus fixing the sealing cover 61 to the front end of the protective shell 11. The movable cover 63 is slidably sleeved on the front end of the sealing cover 61.

[0054] The working principle of the shock-absorbing lithium-ion heavy-duty electric hammer handle structure provided by this utility model is as follows:

[0055] Before starting work, the front end of the movable cover 63 is placed against the wall, and then the motor is started to drive the drill bit 13 to rotate and push forward. While the sealing cover 61 slides at the front end of the movable cover 63, a large amount of dust is generated at the drilling site, which is blocked inside the sealing cover 61 and then flows into the dust collection box 64 for storage.
