Description

Shock absorbing is hammered into shape

Technical field

Industry and daily life utensil are the utility model is related to, is hammered into shape more particularly, to a kind of shock absorbing easy to use.

Background technology

Hammer not only industrially has extensive purposes, but also is the life appliance required for every household, hammer Species is broadly divided into several major classes such as claw hammer, blacksmith's hammer, testing hammer, machine hammer, scaling hammer, claw hammer, and people use hammer Number is also very more, commonly used to tap nail or correct object and knock object open.Hammer is mainly made up of two parts： Tup and hammer handle.Both connection is is rigidly connected, when object is tapped, when particularly harder object, and power Size be difficult to control, the explosive force of common hammer is strong, and the percussion power used is bigger, and the power of bounce-back is bigger, to palm tiger The injury of mouth is also higher, and often occurs collapsing nail, curved nail, the situation of skew nailing, and these phenomenons not only have impact on beating effect, Material is wasted, is also easy to knock the hand of user.At present, it is this kind of although there is the anti-skidding hammer of various shock absorbings on the market Hammer mainly carries out adding plastic pad and some relatively soft materials to handle, although its shockproof effect is it is also possible that tap Effect and feel are simultaneously bad, belong to passive shockproof, it is therefore necessary to design a kind of more efficiently shock absorbing hammer for reducing bounce To solve the above problems.

Utility model content

The purpose of this utility model is to overcome above-mentioned hammer common in the prior art existing deficiency in use, there is provided A kind of use is more stable, reduces impulsive force of the hammer to tiger's jaw, and repeatedly impact will not also injure the shock absorbing hammer of tiger's jaw.

The technical problems to be solved in the utility model is adopted the technical scheme that：Shock absorbing is hammered into shape, and it includes what is be sequentially connected Tup, hammer handle, hammer handle set, shock absorbing chamber are provided with the tup, the shock absorbing intracavitary is provided with shock absorbing mechanism, the shock absorbing machine Structure includes shock absorbing part and shock absorbing block, and the shock absorbing block is arranged on shock absorbing part and is mutually perpendicular to shock absorbing part axis, the shock absorbing Block is cylinder or cuboid.

Further, the shock absorbing part is shock eliminating spring, and the shock eliminating spring includes the bracing ring and bracing ring at both ends Between coil.

The beneficial effects of the utility model：1st, in the presence of shock absorbing mechanism, reduce impulsive force, form and repeatedly beat Hit, can be become more stable when nail is tapped, and be not easy to occur collapsing nail, curved nail, the phenomenon of skew nailing；2nd, it is easier Strike effect is controlled, nail can efficiently, safely, be quickly tapped and impact of the hammer to tiger's jaw can be effectively reduced Power, reduce the injury to human body.

Embodiment

In order that those skilled in the art more fully understand the technical solution of the utility model, combine and have below according to accompanying drawing The utility model is described in further detail in body embodiment.

As shown in Figure 1, 2, by taking claw hammer as an example, the shock absorbing hammer includes tup 1, hammer handle 2, the hammer handle set 3 being sequentially connected, Shock absorbing chamber 4, the preferably round hole of shock absorbing chamber, or square opening, the height of the shock absorbing chamber are provided with the middle part of the tup For 1/3rd or so of tup, the volume of shock absorbing chamber should be no more than 1/3rd of tup, and the shock absorbing intracavitary, which is provided with, to disappear Shake mechanism, the shock absorbing mechanism includes shock absorbing part 6 and shock absorbing block 5, the shock absorbing block be arranged on shock absorbing part and with shock absorbing part axle Line is mutually perpendicular to, and shock absorbing block is cuboid, and the shock absorbing part includes shock eliminating spring, shock absorbing rubber block etc., and the shock absorbing block is iron Block etc..

In fig. 2, the shock absorbing part is shock eliminating spring, in order to make spring steady and in end face stress when stretching equal It is even, need to polish the both ends of spring and tightly during design, these and the circle tightly polished is bracing ring 7, serve supporting role, be left The equal circle of holding pitch, be coil 8, pitch corresponding axial distance between two coils, a kind of specific shock absorbing The technical parameter of spring is：Spring outer diameter is 25mm, manufactures a diameter of 1.5mm of the metal material of spring, and spring inside diameter is 22mm, mean diameter of coil 23.5mm, pitch 2mm..

As shown in figure 3, when common hammer taps object, the time of hammer and object interaction is very briefer, Within the so very briefer time（t1-t2）, active force is rapidly reached very big value, then and quickly drop to zero. Due to being a kind of variable force, it can be difficult to determine this impulse force with the relation changed over time, so as to represent moment relation When, Newton's second law also is difficult to directly use.So we the momentum of impulse force is determined according to momentum theorem possessed by amount Value, hammer rebound after nail is tapped, and stress significantly increases, so hammer derives from right bounce than strike after nail is tapped The percussion power that the speed of hammer is 0 afterwards is also big.

As shown in figure 4, shock absorbing of the present utility model is hammered into shape when object is hit, no matter the shock absorbing hammer during strike How momentum changes, and the phasor difference of the whole story momentum of shock absorbing hammer can all be equal to its momentum.In the presence of shock absorbing mechanism, disappear Shake part（Such as the shock eliminating spring in Fig. 1,2）Stroke inside hammer can taper into, and the direction size of speed also can be therewith Change, and be gradually reduced to zero.The impulse force of spring and sliding block can effectively offset the opposite impulse force of part hammer, impulse force superposition As a result hammer action time is added（t1-t2、t3-t4、t5-t6）.Again because the connection of tup and hammer handle connects for rigidity Connect, the growth of action time, the impulsive force to the user's palm tiger's jaw can be effectively reduced, reduce the injury to human body.

Shock absorbing chamber of the present utility model is formed with the following manner, first, tup point is separated in half into manufacture, in half of tup Centre sets a groove, sets shock absorbing mechanism in groove, then two halves tup is welded and combined；Second, among the tup of entirety Side sets groove, and shock absorbing mechanism is set in groove, then opening welded closure is stayed into a square hole in the front end of tup with end plate For assembling shock absorbing part and shock absorbing block, equipment again welds square hole after entering, to prevent firmly excessive when, shock absorbing Part and shock absorbing block surprisingly fly out；Third, extending to dress shock absorbing mechanism in middle part in tup in the tup hole of dress hammer handle, hammer handle is reassembled. Shock absorbing part can certainly be assembled from the perforate such as bottom or hammer handle junction, in order to keep stability, sealing mode is not built View is using threaded connection, preferably with solder up.

Embodiment of above is only to illustrate the technical solution of the utility model and unrestricted, although with reference to specific embodiment The utility model is described in detail, it will be understood by those within the art that, can be to skill of the present utility model Art scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solutions of the utility model, it all should cover In protective scope of the claims of the present utility model.
