Description

Technical Field

[0001] The present application relates to the technical field of electric hammers, and in particular to an electric hammer capable of reducing dust splashing. Background Art

[0002] An electric hammer drill is an electric rotary hammer drill with a pneumatic hammer mechanism and a safety clutch. It utilizes the principle of piston motion, with compressed gas impacting the drill bit. This requires minimal manual effort and can create holes 6-100mm in hard materials like concrete, brick, and stone. While electric hammers are highly efficient in these materials, they cannot create holes in metal.

[0003] A review of announcement number CN207058497U reveals an impact hammer. The technology disclosed herein "includes a hammer body and an auxiliary handle, the auxiliary handle comprising a sleeve and a handle, the sleeve being sleeved over the hammer body and rotatably engaged with the hammer body, the handle being plugged into the sleeve. The sleeve comprises a first sleeve and a second sleeve, the first sleeve being sleeved over the hammer body, the second sleeve being axially perpendicular to the first sleeve, the end of the second sleeve being connected to the outer circumference of the first sleeve, and the handle being inserted into the second sleeve. The auxiliary handle can rotate around the hammer body, and the angle of the auxiliary handle can be adjusted according to different working conditions, thereby improving operating comfort."

A rotatable push rod 25 is provided at one end of the rotating rod 24, and a transmission rod 26 is provided on one side of the push rod 25. An output rod 27 is provided on one side of the transmission rod 26. The outer surfaces of the output rod 27, the transmission rod 26 and the push rod 25 are jointly provided with a transmission shell 29.

[0033] Reference Figure 2 The outer surface of the shell 1 is covered with a holding frame 4, and a holding rod 5 is fixedly installed at the lower end of the holding frame 4. A handle 6 is installed on one side of the shell 1, and a connecting line 7 is provided at the lower end of the handle 6. An output port 28 for use with an output rod 27 is provided on one side of the shell 1. The electric hammer can be held with both hands through the holding frame 4 and the holding rod 5, which is more stable and safe. The handle 6 can be used to facilitate the staff to hold it, and the electric hammer can be powered by the connecting line 7. The output port 28 can prevent dust from entering the inside of the shell 1 and protect the structure.

[0034] Reference Figure 3 The buffer mechanism 3 includes a buffer frame 37, a damping plate 32, a damping spring 31, a damping ring 30, a locking bead 36, a locking ring 33, and a locking spring 35. The damping plate 32 is fixedly provided on one side of the buffer frame 37, the damping spring 31 is fixedly provided on one side of the damping plate 32, the damping ring 30 used in conjunction with the output rod 27 is fixedly provided on one side of the damping spring 31, a plurality of locking beads 36 used in conjunction with the output rod 27 are movably provided on the outer surface of the transmission housing 29, a slidable locking ring 33 is provided on the outer surface of the transmission housing 29, and a locking spring 35 is fixedly provided on one side of the locking ring 33.

[0035] Reference Figure 3 There are six engaging beads 36, and the six engaging beads 36 are distributed in a ring shape on the outer surface of the transmission housing 29. The inner surface of the buffer frame 37 is fixed to the outer surface of the transmission housing 29 by welding.

The annular distribution of the engaging beads 36 can effectively improve the engaging stability of the engaging beads 36, so that the buffer frame 37 and the transmission housing 29 are fixedly connected to effectively improve the overall stability of the structure. The engaging spring 35 can be limited by the engaging plate 34 to prevent it from slipping out.

[0036] The working principle of the embodiment of the present application is as follows: the motor 20 at the lower end of the housing 1 is started through the transmission mechanism 2, so that the motor 20 can drive the driving gear 21 to rotate through the output end, so that the driving gear 21 can drive the eccentric wheel 23 to rotate through the driven gear 22, and the eccentric wheel 23 can drive the push rod 25 at one end of the rotating rod 24 to move back and forth in the transmission housing 29, so that the push rod 25 can drive the output rod 27 to impact through the transmission rod 26, thereby achieving the purpose of the electric hammer to effectively impact;

The damping plate 32 can be fixed by the buffer frame 37. The housing 1 is opened and the snap ring 33 is slid so that the snap bead 36 can be disengaged from the position limit of the output rod 27, so that the output rod 27 can be replaced. The snap ring 33 can be limited by the snap spring 35, thereby achieving the purpose of effective buffering of the electric hammer.

[0039] The annular distribution of the locking beads 36 can effectively improve the locking stability of the locking beads 36, so that the buffer frame 37 and the transmission housing 29 are fixedly connected to effectively improve the overall stability of the structure. The locking spring 35 can be limited by the locking plate 34 to prevent it from slipping out.
