Abstract
The utility model discloses an inertia stressing hand hammer with a special structure, comprising a hollow hammer and a stressing mechanism in the hammer, wherein, the stressing mechanism is composed of a connecting rod 4 connected with two hammerheads 2, 3 and a plurality of movable metal rings 5 sheathed on the connecting rod 4. In the beating process, the stressing mechanism can generate impact on the hammerheads to enlarge strike force. Compared with an ordinary hand hammer, the utility model has the obvious advantages of overcoming recoil and enhancing strength.
Description
The utility model is a kind of hand hammer of being made up of hammer body and hammer handle, belongs to the percussion tool of special construction.
In the middle of the existing hand hammer, the hammer body part is all made solid, no matter this solid hand hammer by which kind of material is made, rebound effect of various degrees all when hitting, particularly when hammer body is manufactured by materials such as timber, plastics, rubber, the dynamics deficiency of Da Jiing not only, and because the rebound effect aggravation, influenced the stability of operation.This hand hammer is subjected to the restriction of structure, can not produce additional hitting power, can not eliminate rebound effect.
The purpose of this utility model just is the structure of existing hand hammer is improved, and the deficiency at existing hand hammer proposes a kind of hand hammer with inertia boosting mechanism.
For achieving the above object, the solution that the utility model is taked is: hand hammer is made up of hammer body and hammer handle, and wherein hammer body is by the hammer carrier of tubulose, be contained in two tups at hammer carrier two ends and be contained in hammer carrier and two tups between assistor form.Assistor can be the object by metal ball, sheet or other shapes such as copper, iron, lead.One of them tup also can be cast together with hammer carrier.Assistor will guarantee free movable when hand hammer hits.The hammer body shape can be made into cylinder or prism, and manufacturing material can be that metals such as copper, iron or plastics, rubber etc. are nonmetal.
Assistor in the middle of the hand hammer described in the utility model can also be such augmentor, and it is made up of with several mobilizable metal rings that are enclosed within on the connecting rod a connecting rod that is connected between two tups.Connecting rod can adopt with two tups and be threaded, also can an end and tup casting together, the other end is threaded with another tup employing.Becket is made by metals such as copper, iron, lead.The quantity and the size that are enclosed within becket on the connecting rod can be as the criterion with hand hammer this becket when hitting in free activity.
Above-described hand hammer, because the variation of structure, hammer body and hammer handle just can not adopt and traditional add connected mode that wedging is solid from the other end.If hammer handle is a metal, hammer body and hammer handle cast solid promptly can be connected in the mode that casting connects, also can adopt the mode of welding to connect.Can adopt the socket joint of falling the wedge to connect for wooden hammer handle, promptly, cast or the intubate of burn-oning, adopt then to add a socket joint connected mode of falling wedge earlier in the outside of hammer body.
The utility model is owing to adopted special inertia boosting mechanism, so it is in the strike process, just because effect of inertia produces impact to tup, the impact of assistor has strengthened the hitting dynamics of hand hammer to assistor on the one hand, slacken the bounce-back of hand hammer on the other hand, improved strike effect.
The utility model is compared under the same conditions with existing hand hammer has the advantage that significantly overcomes bounce-back, strengthens hitting dynamics and raising operational stability.Again because hand hammer can be by multiple material manufacturing, so the occasion of using is also very extensive.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing: the cutaway view of the utility model embodiment.
Accompanying drawing is an embodiment of the present utility model, and it is by hammer carrier 1, tup 2,3, and connecting rod 4, iron hoop 5, intubate 6, hammer handle 7, chock 8 is formed.One end of connecting rod 4 and tup 2 are what to annotate to one, adopt with the tup 3 of hammer carrier 1 other end to be threaded.The internal diameter of iron hoop 5 is greater than the diameter of connecting rod 4, and its external diameter is less than the internal diameter of brandreth 1, thereby can guarantee that iron hoop 5 can be free movable along connecting rod 4.Hammer body and being connected of hammer handle 7 are to adopt the socket joint of falling the wedge to connect, and promptly are to add chock 8 on hammer handle 7 earlier, insert then in the intubate 6, and the effect by chock 8 links together hammer handle and hammer body securely.Tup 2 is plastics, and hammer handle 7 is wooden, and remainder is made by carbon steel, after the hammer body assembling finishes, get a male and fomale(M﹠F) with striker between hammer carrier 1 and tup 3, the convex surface of hammer carrier 1 is stuck on the concave surface of tup 3, thereby has stoped the rotation of tup 3 when hitting.
Claims (3)
1, a kind of inertia hand hammer, it is made up of hammer body and hammer handle, it is characterized in that hammer body is the hammer carrier (1) by a tubulose, be contained in the tup (2,3) at hammer carrier (1) two ends, and the assistor that is contained between hammer carrier (1) and two tups (2,3) is formed.
2, hand hammer according to claim 1 is characterized in that described assistor is connected the connecting rod (4) between two tups (2,3) by one and several mobilizable beckets (5) of being enclosed within on the connecting rod (4) are formed.
