Abstract

The utility model relates to a hammer with vibration reduction function, which consists of a handle and a hammer head. The hammer head consists of a hammer head main body and a sliding block which is assembled in the hammer head. One end of the hammer head main body is provided with a blind hole. The sliding block and the blind hole adopt clearance fit. The sliding block can slide along the axial direction in the blind hole. The sliding block is provided with a guide groove. A pin is arranged on the hammer head main body. The axial sliding of the sliding block can be stopped through coordination of the pin and the guide groove. When the hammer is used and the hammer head is in the moving process, the sliding block slides toward an opening of one side of the blind hole due to inertia effect. At the moment that the action object is smashed by the hammer, the sliding block rapidly slides toward the bottom of the blind hole due to inertia effect and smashes on the bottom of the blind hole, and the direction of the acting force of the sliding block is just opposite to the direction of the reacting force which is acted on the hammer head and is from the action object of the hammer head so as to take the effect on reducing impact and vibration.

Description

A kind of hammer with vibration-damping function

Technical field

The utility model relates to a kind of hammer, specifically is a kind of hammer with vibration-damping function.

Background technology

As everyone knows, hammer is made up of tup and handle.Tup generally has very big rigidity, will produce in the use to impact and vibration, and long-term the use can be caused damage to palm and arm.

Summary of the invention

In order to overcome the deficiency of existing hammer, the utility model provides a kind of hammer with vibration-damping function.

The scheme that its technical problem that solves the utility model adopts is: tup is an assembly, by the tup main body be assemblied in its inner slide block and form; One end of tup main body has a blind hole, and slide block and this blind hole adopt matched in clearance, and slide block can slide in blind hole vertically; The outer surface upper edge generatrix direction of slide block has a gathering sill, and a socket cap shop bolt is installed on the tup main body, and insert in the gathering sill of slide block the socket cap end of pin; Endwisely slipping of slide block promptly comes spacing by pin and gathering sill.During use, tup is in motion process, and slide block is owing to effect of inertia slides to opening one side of blind hole; Hammer is pounded the moment at effective object, slide block again since effect of inertia rapidly to the basal sliding of blind hole and pound in the blind hole bottom, its active force is just in time opposite with the suffered reaction force direction from the tup effective object of tup, thereby plays the effect that reduces to impact with vibration.

The beneficial effects of the utility model are: the effect of inertia of slide block can reduce tup when using impact and vibration, use comfortable, body health benefits.

Description of drawings

Be illustrated as structural representation of the present utility model.

1. handles among the figure, 2. tup, 3. tup main body, 4. slide block, 5. pin, 6. locking nut, 7. handlebar, 8. taper knob.

The specific embodiment

As shown in the figure, the utility model is made up of handle 1 and tup 2, and tup 2 is by tup main body 3, and slide block 4 and pin 5 are formed.The right-hand member of tup main body 3 has a blind hole, and slide block 4 adopts matched in clearance with this blind hole; Slide block 4 can slide in blind hole vertically; The outer surface upper edge generatrix direction of slide block 4 has a gathering sill, and a socket cap shop bolt 5 is installed on tup main body 3, and insert in the gathering sill of slide block 4 the socket cap end of pin 5; Endwisely slipping of slide block 4 promptly comes spacing by pin 5 and gathering sill.

Handle 1 described in the figure adopts thread connection with tup 2, has internal thread hole on the tup 2, and handle 1 front end is an external threaded, lock with locking nut 6 behind the screw portion precession screwed hole, to prevent becoming flexible this connecting mode convenient disassembly, it is firm to connect, and is difficult for loosening.

Handle 1 described in the figure is made up of handlebar 7 and taper knob 8.Handlebar 7 is a rigid bar, and taper knob 8 is an elastic component, and flexible taper knob 8 tightly is enclosed within on the handlebar 7, grasps taper knob 8 parts during use, can further reduce to impact and vibration, uses more comfortable.

Hammer described in the figure in use, tup 2 in (left) motion process, slide block 4 since effect of inertia slide to opening one side (to the right) of blind hole; Hammer is pounded the moment at effective object, slide block 4 again since effect of inertia slide and pound to the bottom of blind hole (left) rapidly in blind hole bottom, its active force is just in time opposite with the suffered reaction force direction from the tup effective object of tup 2, thereby plays the effect that reduces to impact with vibration.

The blind hole of the employing matched in clearance described in the figure and slide block 4, its cross sectional shape can be circular, also can be non-circular, both consistent matched in clearance that form, and slide block can slide smoothly in blind hole and get final product.

Claims

1. hammer with vibration-damping function, form by handle and tup, tup is made up of tup main body, slide block and pin, it is characterized in that an end of described tup main body has a blind hole, a slide block and its formation matched in clearance are arranged in the blind hole, slide block can slide in blind hole vertically, have gathering sill on the described slide block, on the tup main body pin is installed, endwisely slipping of slide block is next spacing with cooperating of gathering sill by pin.

2. hammer according to claim 1 is characterized in that handle and tup adopt thread connection, and pins with locking nut.

3. hammer according to claim 1 is characterized in that handle end holds part and be with flexible taper knob.
