Abstract
The utility model relates to a pneumatic pick device which comprises a coupling sleeve and a cylinder body which is arranged on the front end of the coupling sleeve. The pneumatic pick device is characterized in that the coupling sleeve is connected with the cylinder body through a clamp ring; a convex-concave groove is arranged on the connecting end of the coupling sleeve; the convex-concave groove corresponding to the coupling sleeve is arranged on the connecting end of the clamp ring; the coupling sleeve and the clamp ring are mutually connected through the convex-concave groove in a matching way; and a fixed sleeve used for connecting is arranged on the outside of the coupling sleeve and the clamp ring. An air exit hole is arranged in the middle part of the cylinder body, and an air guiding cover is arranged at the outside of the air exit hole. Compared with the prior art, the utility model ensures that the stress at the joint is uniform because the coupling sleeve and the cylinder body are connected by means of integrating the convex-concave groove and the fixed sleeve, and the phenomenon of partial fatigue crack can not easily occur, thereby reducing the labor intensity, increasing the efficacy and prolonging the service life; and the air guiding cover can effectively prevent oil from spraying everywhere, thus the work is safe and reliable.
Description
Technical field
The utility model relates to the pneumatic tool of a kind of building, mine, road use, more particularly, relates to a kind of accurate gas pick device.
Background technology
In urban construction or mining process, often need smash old pavement at present, broken concrete foundation, destroy fastening frozen ground, block the coal seam and smash ore, at present the gas pick of using, because structure and material therefor is different, thereby the performance of product has very big difference, and the main problem that exists is: because fracture appears in the single-point location after the fatigue of materials, gas pick is short application life, effect is low, sprays around the oil gas, and it is unreliable to work.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of multipoint positioning is provided, and has buffer, reduces labour intensity, improves effect, the accurate gas pick device that increases the service life.
In order to address the above problem the technical solution of the utility model is such:
A kind of gas pick device, comprise a coupling sleeve and the cylinder body that is arranged on the coupling sleeve front end, it is characterized in that, described cylinder body is connected with coupling sleeve by clamp ring, the link of coupling sleeve is provided with emboss pit, the link of lock sleeve is provided with and the corresponding emboss pit of coupling sleeve, and coupling sleeve cooperatively interacts by emboss pit with clamp ring and is connected, and has to be connected in the arranged outside of coupling sleeve and clamp ring and uses fixed cover.
Described fixed cover is with coupling sleeve and clamp ring socket; Retainer plate one end embeds the coupling sleeve outside, and the other end entangles the clamp ring bottom.
Described clamp ring is connected with cylinder body by fixed teeth.
Described cylinder body middle part is provided with steam vent, in the arranged outside of steam vent air scoop is arranged.
The emboss pit of described coupling sleeve is that multiple spot cooperates equal five equilibrium groove with the emboss pit of clamp ring, and the direction of convex-concave is opposite.
Beneficial effect because the mode that adopts emboss pit to add fixed cover is connected coupling sleeve with cylinder body, makes the junction stressed even, is not prone to the local fatigue phenomenon of rupture, reduces labour intensity, improves effect, has prolonged application life; And be provided with gas hood and effectively prevented to spray around the oil gas, safe and reliable.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of gas pick device described in the utility model.
Fig. 2 is gas pick device coupling sleeve described in the utility model and clamp ring mated condition schematic diagram.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, gas pick comprises with lower member: coupling sleeve 1, fixed cover 2, clamp ring 3, air scoop 4, cylinder body 5, hammer body 6, steam vent 7.
Further referring to Fig. 2, coupling sleeve 1 one ends have emboss pit 11, one end of corresponding clamp ring 3 is provided with emboss pit 51, emboss pit 11 and emboss pit 51 convex-concave directions are the interlock shape on the contrary and mutually, and equal five equilibrium distributes for multiple spot cooperates for emboss pit 11 and emboss pit 51, because employing is that interlock is to connect, the multiple spot contact is located each other, stressed even, can not produce local fatigue, prolonged application life.
Be provided with steam vent 7 at the middle part of cylinder body 5 in addition, air scoop 4 arranged in the arranged outside of steam vent 7, air scoop 4 can effectively prevent oil gas that steam vent 7 discharges to around spray, guaranteed user's personal safety.
Compared with prior art,, make the junction stressed even, be not prone to the local fatigue phenomenon of rupture, reduce labour intensity, improve effect, prolonged application life because the mode that adopts emboss pit to add fixed cover is connected coupling sleeve with cylinder body; And be provided with gas hood and effectively prevented to spray around the oil gas, safe and reliable.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
