Description
Technical field
Double-beat hammer mechanism of the present invention relates to a kind of hammer tool mechanism, especially a kind of improvement mechanism at common hammer.
Background technology
Common hammer always comprises a tup and a hammer handle, and tup is a solid steel cellular construction, and the opposite direction of the attacking head of tup portion also can be provided with a pair of pawl sometimes, forms claw hammer etc.This hammer structure is simple, and is easy to make, durable, and its popularity various places all over the world, almost everyone used this classical hammer structure, also knew very well its practicality, validity to work.
But the hammer structure of this classics also has certain limitation, comprise and to produce tangible reaction force, this reaction force is from tup process hammer handle, act on user's the arm, the power that applies at first is big more, the chatter that reacts on staff is also just strong more, even make those experienced operators also feel pain; In addition, when knocking hard thing, can produce unnecessary vibration, thereby impact point is departed from.
At two above-mentioned drawbacks, there is technical scheme to propose in hammer structure, to be provided with damping device.As: the patent No. 93112933.8 discloses a kind of claw hammer damping device, handle therefrom body stretches out, middle body forms the bellmouth of an elongation, the bellmouth axis aligns with the longitudinal axis of described handle basically, constitutes the elastic shock attenuation body by the stopper of filling in bellmouth and the elastic webbing or the hoop that are stuck in the groove of stopper.The elastic shock attenuation body is partial offset or weaken owing to impact the tup vibration cause at least.
The patent No. 95224765.8 also discloses a kind of Shock-proof harmmer, and the threaded steel elastic rod of front end is housed in hammer handle, thereby the suffered chatter of operator's arm impacts when reducing hammering.
More than two kinds of damping devices all can effectively play cushioning effect, raise labour efficiency.
But these structures all need to destroy existing hammer structure, adopt new manufacture craft, and structure is slightly complicated also.
In addition, existing improvement to hammer structure also only is confined to on the pondering of damping a kind of effectively damping is not arranged as yet, can also form a kind of additional impulsive force in that hammer is inner, thereby increase the dynamics of knocking, the mechanism of improving beating effect.
Summary of the invention
The purpose of double-beat hammer mechanism of the present invention is to provide a kind of double-click effect that has, again the effective hammer mechanism of damping.
For reaching above-mentioned purpose, a kind of double-beat hammer mechanism of the present invention comprises tup and hammer handle, wherein, sealed removable mass is set in the tup.At the inner cavity that forms of tup, described mass moves along the direction that hammer impacts, to being impacted the effect that deposits yields is double-clicked.
For described mass after double-click can reset rapidly, prepare to impact next time, the present invention is provided with sealed movably mass in tup, and movably mass is located by resetting-mechanism.
Described resetting-mechanism comprises spring or has the return unit of spring.
Further, the two ends of described sealed removable mass are pressed into spring.Use two to place the spring at two ends not only to define the position of mass, and when hammer does not knock object, make hammer and common hammer be as good as, whole hammer is one seemingly.
Perhaps, described sealed movably mass end is provided with endoporus, can be an end, also can be that the two ends of mass all are provided with endoporus, stage clip or have spring return unit be partially submerged in the endoporus alignment quality piece.
The outer rim place of the center of gravity of described mass is provided with a bulge loop, by the periphery of the spacing compression spring sleeve of bulge loop at mass.Spring is arranged on the two ends of bulge loop.Also can be a spring, fix on the bulge loop of mass.
Wherein, described bulge loop and mass are structure as a whole.
The end of described mass is provided with inner bolt hole, and also there is an inner bolt hole tup inboard, and the two ends of extension spring are rotated with respectively in two inner bolt holes.
The described structure that is used for the airtight quality piece is threaded closure caps or inserts lid.
When with inserting when cover, this inserts cross section of covering is the trapezium structure of angle slightly.
The present invention is not limited to above-mentioned hermetically-sealed construction.
The present invention double-clicks mechanism and can be arranged in all kinds of hammers or the existing in the world hammer tup.
Double-beat hammer mechanism of the present invention also can be used in other instrument, as: hoe, hatchet, axe, tennis racket, golf clubs etc.But be not limited to above-mentioned giving an example.
Advantage of the present invention is:
1, mass moves along the direction that hammer impacts in the tup cavity, forms the process of beating of once double-clicking, and this extra percussion power acts on and impacted object, has just promoted the effect of knocking greatly;
2, can reduce or eliminate bounce-back or the rebound effect power that traditional hammer produced in when work, make knock more accurate, more stable;
3, have the effect that suppresses chatter, can reduce or eliminate the chatter of reaction on user's arm, use more smoothly, more convenient;
4, simple in structure, can form by common hammer transformation;
5, when not using, resetting-mechanism makes hammer and common hammer be as good as, and whole hammer is one seemingly;
6, knock the back resetting-mechanism and make mass to get back to the home position rapidly under the effect of resetting-mechanism, this knocks can not to influence next;
7, resetting-mechanism is best, cheap and easy to get especially with the spring, system stability, and effect is remarkable;
8, double-beat hammer mechanism of the present invention can be applied to form of ownership, in the hammer that all generally use in each place.
