Abstract
The utility model provides a gadder hand shank structure which comprises a hand rod, a fixed rod, two first connecting shafts and two second connecting shafts, the length of the handle rod is the same with or slightly shorter than that of the fixed rod, and the handle rod and the fixed rod are fixedly connected through the first connecting shafts. Through holes are formed at one ends of the second connecting shafts, nut placing holes are formed at the other ends of the second connecting shafts, and the fixed rod penetrates through the through holes and is fixedly connected with the second connecting shafts. The gadder hand shank structure effectively reduces shaking of a hand portion caused when a gadder works, enables operation to be comfortable, effectively protects working security of an operator, and has important production practical significance.
Description
Technical field
The utility model relates to a kind of handle arrangement, especially a kind of rock drill handle arrangement.
Background technology
Rock drill is mainly used in mining and tunnelling and railway, in the engineering constructions such as water conservancy, existing rock drill belongs to light-duty manually-operated type mostly, by handle and the organization that can produce operation power, in use need the direct operating grip dominated by hand of operator, yet along with the motion of rock drill high-frequency reciprocating, can form strong vibrations, hand to operating personnel damages, easily cause pointing nerve numb after the long period of operation and refer in vain sick, therefore existing handle is improved, make its in process of production effective shock, have very important production practices meaning.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rock drill handle arrangement with shockproof function.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of rock drill handle arrangement, formed by handlebar stem, fixed bar, two the first connecting axles and two the second connecting axles, the length of described handlebar stem and fixed bar are same or slightly shorter in fixed bar, described handlebar stem is fixedly connected with by the first connecting axle with fixed bar, described the second connecting axle one end is provided with through hole, the other end is the nut putting hole, and fixed bar passes through hole and is fixedly connected with the second connecting axle.
Preferably, above-mentioned rock drill handle arrangement, described fixed bar middle part is two parallel rod shaped structure.
Preferably, above-mentioned rock drill handle arrangement is nested with gum cover on the described handlebar stem.
Preferably, above-mentioned rock drill handle arrangement, described two the first connecting axles vertically are fixed in respectively the two ends of handlebar stem.
Preferably, above-mentioned rock drill handle arrangement, described the second connecting axle is the triangle configuration.
The utility model structure has following beneficial effect:
Above-mentioned rock drill handle arrangement has effectively reduced the vibrations that rock drill work causes hand in the use procedure, so that operation is more comfortable, has effectively protected operator's work safety, has very important production practices meaning.
Description of drawings
Fig. 1 is the structural representation of rock drill handle arrangement described in the utility model;
Fig. 2 is the upward view of rock drill handle arrangement described in the utility model.
Among the figure: 1-handlebar stem 2-gum cover 3-the first connecting axle 4-fixed bar 5-the second connecting axle
The specific embodiment
For further specifying the utility model, now cooperate accompanying drawing to be described in detail:
As depicted in figs. 1 and 2, described rock drill handle arrangement, a kind of rock drill handle arrangement, by handlebar stem 1, fixed bar 4, two the first connecting axles 3 and two the second connecting axles 5 form, be nested with gum cover 2 on the described handlebar stem 1, the length of this handlebar stem 1 slightly is shorter than fixed bar 4, described handlebar stem 1 is fixedly connected with by two the first connecting axles 3 with fixed bar 4, described two the first connecting axles 3 vertically are fixed in respectively the two ends of handlebar stem 1, described the second connecting axle 5 is the triangle configuration, wherein said the second connecting axle 5 one ends (place, base) are provided with two through holes, the other end (drift angle place) is the nut putting hole, described fixed bar 4 middle parts are two parallel rod shaped structure, and this rod shaped structure of fixed bar 4 is passed through hole and is fixedly connected with the second connecting axle 5.
On concrete the application, the nut putting hole of above-mentioned rock drill handle arrangement by the second connecting axle 5 got final product with the body nut that can produce operation power is fixing.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
