Abstract

The utility model provides a shock -absorbing hammer, include tup, elastic component and shock attenuation pipe, wherein, the tup has and strikes the through -hole that the direction is the same with the tup, elastic component part compression back sets up in the through -hole, the shock attenuation pipe is hollow structure, and the cover is on the tup, the inner wall of elastic component's both ends laminating shock attenuation pipe. Its advantage lies in through setting up elastic component and shock attenuation pipe between tup and handle, power when elastic component absorbs the tup and strikes. Elastic component sets up simple structure in the tup, and the volume and the weight that do not need additionally to increase the hammer just can significantly reduce and strike the shaking force of production.

Description

Damping hammer

Technical field

The utility model relates to a kind of hammer, particularly a kind of damping hammer.

Background technology

Hammer is a kind of common tool blunt, can be used for build, moulding also can be used for destroy, dismounting, various operation occasion all need use.

Time hammer knocks, due to reaction force, violent impulsive force easily can cause hand pain, and long period of operation personnel may cause hand muscle damage.

Some hammers use the handle of plastics to reduce a fraction of jerk power, for alleviating the injury to user.But the force rate reduced is more limited, for Long-Time Service person, still cannot avoid the injury of hand.

Utility model content

A kind of damping hammer provided of the present utility model, to overcome the defect of above-mentioned prior art, raises the efficiency.

The utility model provides a kind of damping hammer, comprises, tup, elastic parts and damping tube; Wherein, tup has and knocks the identical through hole in direction with tup; Be arranged on after elastic parts Partial shrinkage in through hole; Damping tube is hollow structure, is enclosed within tup; The inwall of the two ends laminating damping tube of elastic parts.

Further, the utility model provides a kind of damping hammer, can also have such feature: elastic parts comprises spring and two round parts; Two round parts are separately positioned on the two ends of spring.

Further, the utility model provides a kind of damping hammer, can also have such feature: circle part one end is arc-shaped surface or spherical calotte, and the other end embeds in spring.

Further, the utility model provides a kind of damping hammer, can also have such feature: also comprise the second rotating shaft; One deck cushion is set in damping tube.

Further, the utility model provides a kind of damping hammer, can also have such feature: tup and damping tube are fixed by pin, pin direction and through hole direction perpendicular.

Further, the utility model provides a kind of damping hammer, can also have such feature: pin is arranged on the rear side of through hole.

Further, the utility model provides a kind of damping hammer, can also have such feature: also comprise handle, be wrapped in outside damping tube.

Further, the utility model provides a kind of damping hammer, can also have such feature: handle is plastic material.

The utility model provides a kind of damping hammer, and by arranging elastic parts and damping tube between tup and handle, elastic parts absorbs power when tup knocks.It is simple that elastic parts is arranged on tup inner structure, do not need the volume and weight additionally increasing hammer just can greatly reduce the shaking force knocking generation.

The utility model provides a kind of damping hammer, and the damping tube of hollow contacts with elastic parts arc surface, the transmission of further reduced force, and the cushion arranged in damping tube absorbs the impulsive force that damping tube receives.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Damping hammer comprises: tup 10, elastic parts 20, damping tube 30, handle 40 and pin 50.

Fig. 1 is the structural representation of tup.

As shown in Figure 1, tup 10 has with damping tube 30 link and knocks the identical through hole in direction 11 with tup.The tail end of tup 10, is namely positioned on rear side of through hole 11, has pin hole 12.Through hole 11 and pin hole 12 perpendicular.

Fig. 2 is the structural representation of elastic parts.

As shown in Figure 2, elastic parts 20 comprises spring 21, upper round part 22 and lower round part 23.Upper round part 22 is arranged on the upper end of spring 21, and lower round part 23 is arranged on the lower end of spring.

Fig. 3 is the structural scheme of mechanism of upper round part.

Upper round part 22 one end is arc-shaped surface or spherical calotte 22-1, and the other end is the cylinder 22-2 being less than spring 21 internal diameter.The cylinder 22-2 of upper round part 21 embeds in the internal diameter of spring, plays stable effect.Arc-shaped surface or spherical calotte 22-1 are in the upside of spring 21.Lower round part 23 structure is identical with upper round part, and cylinder embeds the lower end of spring 21.

Fig. 4 is the structural representation of tup and elastic parts.

As shown in Figure 4, elastic parts 20 is arranged in the through hole 11 on tup 10, and spring 21 is in some compression.

Fig. 5 is the front view of damping tube.

Fig. 6 is the left view of damping tube.

As shown in Figure 5 and Figure 6, damping tube 30 is hollow structure, and the position corresponding to the pin hole 12 of tup 10 has pin hole 31.Damping tube 30 inside can also arrange one deck cushion.

The structure that the position that damping tube 30 is connected with tup is hollow it should be noted that, as long as can realize cushioning effect of the present utility model.Damping tube 30 weight that to be all hollow-core construction be in order to alleviate whole hammer body.

Fig. 7 is tup and damping tube annexation structural representation.

As shown in Figure 7, damping tube 30 is enclosed within tup 10, spring 21 Partial shrinkage in through hole 11, and elastic force makes the arc surface of round part 22 and lower round part be fitted on the inwall of damping tube 30.

Both, through the pin hole on tup and damping tube, are fixed together by pin 50.

Fig. 8 is the structural representation of damping hammer.

As shown in Figure 8, finally outside damping tube at the handle 40 of cover last layer plastic material.Certainly, according to practical set technique, after first overlapping upper handle, with pin, three can be fixed together.

When tup knocks object, usual impulsive force can be transmitted on handle, and user is subject to reaction force, can cause fatigue, injure even.

The damping hammer operation principle that the utility model provides: knock object, when reaction force will be delivered to the damping tube be attached thereto by tup, spring can produce compressive deformation, the power of absorption portion.And the cushion of two round part contact damping tube inwalls, impulsive force is absorbed again.Finally, the handle of plastic material also can the active force of absorption portion.Like this, when the reaction force of tup is delivered to user, greatly reduce.
