Hammer for equipment maintenance

Abstract

The invention discloses a hammer for equipment maintenance. Hammer heads made of different materials can be switched by rotating an auxiliary rotary hammer by cooperation of a main hammer and the auxiliary rotary hammer, and thus, the hammer is quick to switch and portable. The hammer is characterized in that a damping grip sleeves one end of a hammer handle, and is made of a rubber material, anti-skid lines are arranged on the damping grip, and one end of the damping grip protrudes outwards to form a limit block; one end of a connecting piece is arranged at the bottom of one end of the damping grip, and the other end of the connecting piece is bent and extends downwards reversely and obliquely towards one end of the connecting piece, is then bent and extends for a certain distance reversely and horizontally, and finally, is bent obliquely downwards; one end of a nail pick piece is arranged at the obliquely downward bent part of the connecting piece and is fixed by a fixing screw, theother end of the nail pick piece is bent downwards for a certain distance and extends horizontally, the other end of the nail pick piece is divided into two pieces, and a nail pick groove is formed between the two pieces.

Description

technical field [0001] The invention relates to a hand hammer for equipment maintenance, relates to a hand hammer used for maintenance of mechanical equipment, and belongs to the field of hardware tools. In particular, it relates to a hand hammer which can switch hammer heads of different materials through the cooperation of the main hammer head and the auxiliary rotary hammer head by rotating the auxiliary rotary hammer head. The switching is quick and the hand hammer is convenient to carry.

Problems solved by technology

[0002] At present, when maintaining mechanical equipment, in order to ensure the minimum friction in the transmission process, different materials are used to ensure the overall service life, such as the material of the bearing bush and the shaft, the shaft and the transmission wheel on the shaft Due to the different materials, when performing maintenance and disassembly, it is necessary to select different hammer heads for knocking, disassembly or installation. At present, the commonly used materials for hammer heads are copper, rubber and steel, and steel is used for ordinary parts. However, the material is relatively soft to avoid indentation on the surface, copper or rubber is used as the hammer head, but the existing hammer heads are all made of the same material, and a hammer cannot adapt to different For the installation and disassembly of material parts, it is necessary to prepare more hammers of different materials for maintenance.

[0003] Publication No. CN208068198U discloses a hand hammer with a replaceable hammer core, which includes a hammer handle, a hammer head and a hammer core. It is characterized in that the hammer head includes a hammer body and a hammer cover; the hammer body is provided with a housing cavity; The hammer cover is arranged on the accommodation chamber and is detachably connected with the hammer body; the hammer core is arranged in the accommodation chamber and is detachably connected with the accommodation chamber. The device is provided with a replaceable vertical core, but the replacement operation is cumbersome and cannot be Quickly switch between hammer heads of different materials

[0004] Publication No. CN203918968U discloses a hand hammer for disassembling precision smooth surface parts, that is, the hand hammer includes a handle and a hammer head, the handle is vertically centered on one side of the hammer head, and the hand hammer also includes two Two nylon blocks, the two ends of the hammer head are respectively provided with pits, and the two nylon blocks are respectively arranged in the pits at the two ends of the hammer head. The performance is poor, and it is necessary to carry multiple nylon blocks as spares, and it is troublesome to replace

[0005] Publication number CN208375216U discloses a hand hammer with adjustment function, including a hand hammer body, the hand hammer body includes a handle and a connecting block, one end of the handle is provided with a bottom cover, an external thread and a wrench, and the inside of the bottom cover A groove is provided and an internal thread is provided in the groove. The bottom cover is installed on the bottom of the handle through the cooperation of the internal thread and the external thread. One side of the handle is provided with a finger sleeve, and the other side of the handle Finger cot 2 is provided on the side, and the connection block and the handle are connected by a shock-absorbing spring. One side of the connection block is provided with a frame, and the other end of the connection block is provided with a hammer head 2. There is a slot, and the hammer head and the rotating shaft are arranged in the slot. The device adopts the form of a rotating wheel to switch, the overall volume of the hammer head increases, it is inconvenient to use and carry, and the fixing stability when switching is poor.
