Abstract
The utility model relates to a kind of engineering hammer, comprise tup and be the hammer handle of the hungry structure of thin wall cavity, the inside of described hammer handle is filled with vibration-absorptive material layer, described hammer handle is provided with protective cover, described protective cover is connected with hammer handle by the fixed cover on it, the upper portion of described protective cover is left recessed arcuate structure, lower portion is left recessed arcuate structure, and the lateral arcs line length in upper portion cross section is greater than the lateral arcs line length in lower portion cross section, on described hammer handle, is positioned at protective cover right side and overlaps flexible screwed pipe cover.The utility model is simple in structure, reasonable in design, and when tup is knocking in process, elasticity screwed pipe overlaps with vibration-absorptive material layer and not only can absorption portion shake, thereby effectively reduces to clash into the impact of the vibrations that produce on the generation of workman's hand; By at hammer handle, protective cover being set, in the time that hammer carries out fragmentation to object, protective cover can prevent that the stone splashing from damaging workman's hand.
Description
Technical field
The utility model relates to hardware & tools technical field, relates in particular to a kind of engineering hammer.
Background technology
Hammer is generally all made up of tup and hammer handle.Wherein, hammer handle is wooden mostly or glass fibre is made, and tup is provided with jack, and the top of hammer handle is plugged in the jack of tup.No matter the hammer handle of this hammer is wooden, or glass fibre, hammer handle is not only wasted material like this, and weight is large, be inconvenient to carry and use, simultaneously larger to the vibrations of workman's hand in the process of knocking, affect workman's work, hammer having many uses in engineering simultaneously, can be used for fragmentation, nail and the multiple use such as nail nipping, in this process, particularly in the time carrying out fragmentation, easily produce the stone splashing, and workman's hand does not block, the stone splashing easily injures workman's hand by a crashing object, causes potential safety hazard.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of engineering hammer is provided.
The utility model is to be achieved through the following technical solutions:
A kind of engineering hammer, comprise tup and be the hammer handle of the hungry structure of thin wall cavity, the inside of described hammer handle is filled with vibration-absorptive material layer, described hammer handle is provided with protective cover, described protective cover is connected with hammer handle by the fixed cover on it, and the upper portion of described protective cover is left recessed arcuate structure, and lower portion is left recessed arcuate structure, and the lateral arcs line length in upper portion cross section is greater than the lateral arcs line length in lower portion cross section, on described hammer handle, is positioned at protective cover right side and overlaps flexible screwed pipe cover.
As preferably, described vibration-absorptive material layer is that sponge material is made.
As preferably, described fixed cover is fastenedly connected with hammer handle or is threaded.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the utility model is filled vibration-absorptive material layer by outside cover elasticity screwed pipe cover and hammer handle inner side at hammer handle, when tup is knocking in process, elasticity screwed pipe overlaps with vibration-absorptive material layer and not only can absorption portion shake, thereby effectively reduces to clash into the impact of the vibrations that produce on the generation of workman's hand; By at hammer handle, protective cover being set, in the time that hammer carries out fragmentation to object, protective cover can prevent that the stone splashing from damaging workman's hand.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1. tup; 2. hammer handle; 3. vibration-absorptive material layer; 4. elasticity screwed pipe cover; 5. fixed cover; 6. upper portion; 7. lower portion.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of engineering hammer, comprises tup 1 and is the hammer handle 2 of the hungry structure of thin wall cavity, the inside of described hammer handle 2 is filled with vibration-absorptive material layer 3, and described vibration-absorptive material layer 3 is made for sponge material.
The part vibrations and the noise that when can be good at like this absorbing hammer and knocking, produce, described hammer handle 2 is provided with protective cover, in the time that hammer carries out fragmentation to object, protective cover can prevent that the stone splashing from damaging workman's hand, and protective cover can adopt the light material of plastics to make.Described protective cover is connected with hammer handle 2 by the fixed cover 5 on it, and described fixed cover 5 is fastenedly connected or is threaded with hammer handle 2, and this arranges according to actual needs.The upper portion 6 of described protective cover is left recessed arcuate structure, lower portion 7 is left recessed arcuate structure, and the lateral arcs line length in upper portion 6 cross sections is greater than the lateral arcs line length in lower portion 7 cross sections, in the time that workman's hand is held hammer handle 2, the area of the upside of hand is large, the area of downside is little, protective cover arranges like this and meets ergonomics, the preventing of the maximum efficiency stone that splashes injures workman's hand by a crashing object, on described hammer handle 2, be positioned at protective cover right side and overlap flexible screwed pipe cover 4, when tup 1 is knocking in process, elasticity screwed pipe cover 4 can effectively reduce to clash into the impact of the vibrations that produce on the generation of workman's hand.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
