Abstract
The utility model relates to a tool of engineering buildings, in particular to a pneumatic pickaxe. In the structure, a connecting sleeve (7) is arranged between a middle pickaxe barrel (1) and a pickaxe handle (4); the connecting sleeve (7) is in thread connection with the pickaxe barrel (1) through raised teeth arranged at the inner wall; a gear ring (8), a buffer ring (9) and a shaft check ring (10) are arranged at the lower end face of the connecting sleeve (7) in sequence; the gear ring (8) is fixedly connected to the pickaxe barrel (1) by inner teeth arranged at the inner wall; a gas connecting pipe (6) is fixedly connected in a nut (13) through an O-shaped ring (12) arranged at the outer wall of the gas connecting pipe (6); the nut (13) is in thread connection with a connecting pipe (5); the end part of the gas connecting pipe (6) inside the nut (13) and the end part of the connecting pipe (5) are tightly connected by a hole baffle ring (14). The pneumatic pickaxe is firmer, the looseness is not easily caused, and the exhaust is more timely and smooth.
Description
Technical field
The utility model relates to a kind of engineering construction instrument, relates in particular to a kind of gas pick.
Background technology
Primordial Qi pick exists three shortcoming and defect on project organization in actual use:
1, gas pick exhaust outlet Position Design is unreasonable, and exhaust resistance is large, and exhaust has some setbacks.Its impact energy is not broken out out completely, and easily freeze in the winter time, can not work continuously.
2, it is easily loosening that gas pick " pick cylinder " and " coupling sleeve " connect screw thread.Intrinsic anti-loose structure just used a pin and also gap very large.Gas pick is shaken and is large when operation, is easy to cause pin come off and cause connection thread looseness.Thereby reduced the impact energy of gas pick, the serious gas pick part that also can damage.
3, gas pick air inlet access part is loosening and inconvenient operation easily.Intrinsic air inlet pipe access part does not have locking measure, and after the upper gas pick of air inlet pipe connection, between the gentle pick of tracheae, there is no rotary place.During actual use, gas pick can change position and direction at any time according to operation needs, at this moment air inlet rubber pipe (general length 10-20 rice) can only be to tag on to the rotation of gas pick, be easy to make air inlet access part " connecting tube " thread looseness, thereby cause gas leakage and malfunction.
Utility model content
The purpose of this utility model is to provide a kind of gas pick, has solved original gas pick structure insecure, and pick cylinder junction and tracheae junction easily get loose and cause the problem of gas leak phenomenon.
For addressing the above problem, technical solution adopted in the utility model is:
A gas pick, comprises interconnective pick rod part, pick body part and helve part successively, and wherein said pick body part mainly consists of pick cylinder, pick body and spool, and pick body and spool are arranged in pick cylinder, and pick body and pick rod are partly connected; Described helve part mainly consists of helve, tube connector and trachea, between described pick cylinder and helve, be provided with adapter sleeve, the lobe that adapter sleeve arranges by its inwall and pick cylinder are threaded, in the lower surface of adapter sleeve, be disposed with gear ring, buffering ring and shaft block ring, described gear ring is connected on pick cylinder by the internal tooth on its inwall; Described trachea is connected in nut by the O type circle being arranged on its outer wall, and nut thread is connected on tube connector, and the end of the trachea of nut inside is closely connected with back-up ring by hole with the end of tube connector.
Further technical scheme is, described pick cylinder is provided with the circular hole of at least six outside exhausts.
Further technical scheme is, on described buffering ring, cover has O type circle.
Further technical scheme is, the junction of described tube connector and pick cylinder is provided with tube connector packing ring.
The beneficial effect that adopts technique scheme to produce is: the utility model adopts gas pick to adopt gear ring type locking mode, thereby this thread connection place can not become flexible the normal operation that has guaranteed gas pick when the operation of gas pick; Between tube connector and trachea, can rotate, thereby make gas pick more convenient and flexible in use, the increase of the circular hole that exhaust of the present utility model is used in addition, makes its exhaust timely, smooth and easy.Thereby make the impact energy of gas pick perform to maximum.And because exhaust is timely, clean, so operation can not freezed yet in the winter time.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of a kind of gas pick of the utility model.
The specific embodiment
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.
Fig. 1 shows an embodiment of a kind of gas pick of the utility model: a kind of gas pick, comprise interconnective pick rod part, pick body part and helve part successively, wherein said pick body part mainly consists of pick cylinder 1, pick body 2 and spool 3, pick body 2 and spool 3 are arranged in pick cylinder 1, and pick body 2 and pick rod are partly connected; Described helve part mainly consists of helve 4, tube connector 5 and trachea 6, between described pick cylinder 1 and helve 4, be provided with adapter sleeve 7, the lobe that adapter sleeve 7 arranges by its inwall and pick cylinder 1 are threaded, in the lower surface of adapter sleeve 7, be disposed with gear ring 8, buffering ring 9 and shaft block ring 10, described gear ring 8 is connected on pick cylinder 1 by the internal tooth on its inwall; Described trachea 6 is connected in nut 13 by the O type circle 12 being arranged on its outer wall, and nut 13 is threaded on tube connector 5, and the end of the trachea 6 of nut 13 inside uses back-up ring 14 to be closely connected with the end of tube connector 5 by hole.
Thereby the gear ring 8 between pick cylinder 1 and adapter sleeve 7, buffering ring 9 and shaft block ring 10 can not become flexible the normal operation that has guaranteed gas pick in this thread connection place when the operation of gas pick; And trachea 6 can be done 360 degree rotation and don't gas leakage in nut 13 the insides, hole, the rubber tube of trachea 6 and outside is connected, and whole like this gas pick can rotate around trachea 6 and rubber tube, thereby makes gas pick more convenient and flexible in use.
According to a preferred embodiment of a kind of gas pick of the utility model, described pick cylinder 1 is provided with the circular hole of at least six outside exhausts, and the increase of the circular hole of exhaust makes its exhaust timely, smooth and easy.Thereby make the impact energy of gas pick perform to maximum, and because exhaust is timely, clean, so operation can not freezed yet in the winter time.
According to a preferred embodiment of a kind of gas pick of the utility model, on described buffering ring 9, cover has O type circle 11.
According to a preferred embodiment of a kind of gas pick of the utility model, the junction of described tube connector 5 and pick cylinder 1 is provided with tube connector packing ring 15.
