Abstract
The utility model relates to a damping structure in an electric hammer or a hammer drill, in particular to a handle damping structure in the electric hammer or the hammer drill, which comprises a mainbody of the electric hammer or the hammer drill and a handle, wherein the mainbody consists of a case and a motor casing, the upper end and the lower end of the handle are respectively connected with the case and the motor casing, the upper end of the handle is connected with the case by adopting a spring damping mechanism, and the lower end of the handle is connected with the motor casing by adopting a damping rubber mechanism. The damping structure has the following advantages: the damping design at the upper part and the lower part of the handle is utilized to reduce the adverse effect of hammering reacting force on a user, lead the time of fatigue in work to be greatly prolonged, and improve the work efficiency.
Description
Technical field
The utility model relates to the shock-damping structure of a kind of electric hammer or hammer drill, the handle shock-damping structure in particularly a kind of electric hammer or the hammer drill.
Background technology
Electric hammer, hammer drill are kind of instruments that relies on rotation and hammering that working media is removed, if the reaction force major part of its hammering acts on human body, easily cause and grip finger and produce numb, phenomenon such as turn white, it is serious also needs therapeutic treatment, many electric hammers, hammer drill are not have shock-damping structure on the existing market, its handle 3 and casing are directly to be connected and fixed with screw, what it adopted is to be rigidly connected, the reaction force of hammering does not weaken and just directly affacts on the arm like this, and the user is using in its short time with regard to susceptible to tired.
The utility model summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of electric hammer of the reaction force that can absorb hammering or the handle shock-damping structure in the hammer drill are provided.
In order to achieve the above object, the utility model adopts following technical scheme: the handle shock-damping structure in electric hammer or the hammer drill, the main body and the handle that comprise electric hammer or hammer drill, main body is made up of casing and motor casing, the upper and lower side of handle is connected with motor casing with casing respectively, adopt spring shock absorption mechanism to be connected between handle upper end and the casing, handle, at its lower end is connected with employing yielding rubber mechanism between the motor casing.
For a kind of optimization of the present utility model, the elasticity of handle upper end and casing connects and composes and comprises screw, compression spring and pad, screw is inserted in pad successively and is connected with the screwed hole of casing one side with the compression spring, and the upper end of handle is provided with the damping storehouse, and the edge of pad snaps in the damping storehouse.
For a kind of optimization of the present utility model, the elasticity of handle, at its lower end and motor casing connects and composes the bearing pin that comprises on the motor casing, the pin-and-hole and the yielding rubber of handle, at its lower end, and pin-and-hole is connected with bearing pin, and is provided with yielding rubber in pin-and-hole and the bearing pin joint gap.
For a kind of optimization of the present utility model, be provided with rubber sleeve between handle upper end and the casing.
The utility model is compared with background technology, has by the damping design at upper and lower two positions of handle to reduce the harmful effect of hammering reaction force to the user, and the time that makes work fatigue occur greatly prolongs, and has improved efficiency.
Description of drawings
Fig. 1 is the schematic diagram of the handle shock-damping structure in electric hammer or the hammer drill.
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
The specific embodiment
Embodiment 1: with reference to Fig. 1.Handle shock-damping structure in electric hammer or the hammer drill, the main body and the handle 7 that comprise electric hammer or hammer drill, main body is made up of casing 1 and motor casing 8, the upper and lower side of handle 7 is connected with motor casing 8 with casing 1 respectively, adopt spring shock absorption mechanism to be connected between handle 7 upper ends and the casing 1, handle 7 lower ends are connected with employing yielding rubber mechanism between the motor casing 8.
Embodiment 2: with reference to Fig. 1.Spring shock absorption mechanism comprises screw 5, compression spring 3 and pad 4, and screw 5 is inserted in pad 4 successively and is connected with the screwed hole of casing 1 one sides with compression spring 3, and handle 7 upper ends are provided with damping storehouse 6, and the edge of pad 4 snaps in the damping storehouse 6.Be provided with rubber sleeve 2 between handle 7 upper ends and the casing 1.When machine works, the reaction force of hammering is delivered on the handle 7 after can sponging a part of kinetic energy by the compression of compression spring 3 again, and this reduces the shock energy of grip portions greatly.
Embodiment 3: with reference to Fig. 1.Yielding rubber mechanism comprises the bearing pin 9 on the motor casing 8, the pin-and-hole 11 and the yielding rubber 10 of handle 7 lower ends, and pin-and-hole 11 is connected with bearing pin 9, and is provided with yielding rubber 10 in pin-and-hole 11 and bearing pin 9 joint gaps.The compression of also having passed through yielding rubber 10 when the reaction force of the hammering of electric hammer or hammer drill is delivered on the handle 7 like this forms buffering effect and is delivered on the handle 7 again, active force is greatly reduced, and handle 7 is done certain rotation with bearing pin 9, thereby improves damping effect once more.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
