Description
Technical field
The utility model relates to a kind of mechanical device, specifically is meant a kind of detachable Matheson and Dresser joint.
Technical background
All there is the superelevation phenomenon in now a lot of engineering trucks, could guarantee transportation after all must dismantling operator cabin earlier when transportation.Engineering truck is before dispatching from the factory, and each accessory all need be done debugging, comprises air-conditioning system, and air-conditioning system just must be filled fluorine earlier when doing debugging.When the engineering truck traffic requirements is torn operator cabin open,, tear open and again air-conditioning duct be dismantled after operator cabin just must have been put fluorine to air-conditioning system earlier because the A/C evaporator assembly is installed in the operator cabin inboard.When arriving the destination assembling, must air-conditioning duct be connected again again, fill fluorine once more Deng engineering truck.This has just caused the reduction of working efficiency and the waste of resource.
In unloading process, often cause the outflow of device interior liquid, be unfavorable for the normal operation of equipment.
The model utility content
The utility model is at deficiency of the prior art, proposes a kind of convenience, joint efficiently.
The utility model is achieved by following technical proposals:
A kind of detachable Matheson and Dresser joint, comprise detachable Matheson and Dresser joint body, detachable Matheson and Dresser joint seat, wherein detachable Matheson and Dresser joint body comprises joint body, in joint body inside spring is arranged, one end of spring is supported by the step of joint body inside, the other end of spring contacts with spool, and a seal ring is arranged between spool and joint body; One end of spool is positioned at the cone cavity of joint body inside, and the cone cavity is necessary in a this patent shape, has only a end when spool in the cone cavity, and spool is subjected to external force to do the time spent, can carry out displacement in the cone cavity; Because of the cross section of cone cavity is inequality, and the cross section of spool is constant, so along with after spool moves, the gap occurred between spool and awl cavity in the cone cavity, joint is inner here just forms perforation; And when detachable Matheson and Dresser joint body separated with detachable Matheson and Dresser joint seat, then spool was subjected to the elastic force effect of spring and withstands, and formed sealing between spool and cone cavity; Detachable Matheson and Dresser joint seat comprises this seat of joint, and this inside of joint is cavity, in this end that docks with joint body of joint thimble is arranged, and between thimble and this seat of joint seal ring is arranged.When detachable Matheson and Dresser joint body was connected with detachable Matheson and Dresser joint seat, thimble dock with spool, and thimble has active force spool is pushed away toward detachable Matheson and Dresser joint intracoelomic cavity, formed the gap thereby make between spool and cone cavity, and the formation perforation.
The utility model comprises detachable Matheson and Dresser joint seat and detachable Matheson and Dresser joint body composition, when it is connected with air-conditioning system, be filled with in air-conditioning system under the situation of freon, when detachable Matheson and Dresser joint seat was connected with detachable Matheson and Dresser joint body, then freon communicated in air-conditioning system; When detachable Matheson and Dresser joint seat disconnected with detachable Matheson and Dresser joint body, then freon disconnected in air-conditioning system, but can not cause freon to leak.
The utility model during engineering truck dismounting operator cabin, only need separate detachable Matheson and Dresser joint seat and detachable Matheson and Dresser joint body behind the detachable Matheson and Dresser joint of utilization on the air-conditioning system, just can satisfy the dismounting of operator cabin, and freon also can be deposited in the air-conditioning system.When arriving the destination assembling, only need combine detachable Matheson and Dresser joint seat and detachable Matheson and Dresser joint body, just can satisfy freon in air-conditioning system, to circulate, need not fluoridize once more Deng engineering truck.Effectively raise working efficiency, also reduced the waste of resource.
Beneficial effect: can effectively increase work efficiency, reduce the waste of resource, and easy for installation etc.

Embodiment
Specify with regard to enforcement of the present utility model below:
Embodiment 1
According to Fig. 1, Fig. 2, structure shown in Figure 3, assemble a detachable Matheson and Dresser joint, it comprises detachable Matheson and Dresser joint body 1, detachable Matheson and Dresser joint seat 2, wherein detachable Matheson and Dresser joint body 1 comprises joint body 3, in joint body 3 inside spring 4 is arranged, one end of spring 4 is supported by the step of joint body 3 inside, and the other end of spring 4 contacts with spool 6, and a seal ring 5 is arranged between spool 6 and joint body 3; One end of spool 6 is positioned at the cone cavity of joint body 3 inside; Detachable Matheson and Dresser joint seat 2 comprises this seat of joint 8, and this seat of joint 8 inside are cavity, joint this 8 with a end that joint body 3 docks in thimble 7 is arranged, between thimble 7 and this seat of joint 8 seal ring 5 is arranged.When it is connected with air-conditioning system, be filled with in air-conditioning system under the situation of freon, when detachable Matheson and Dresser joint seat 2 was connected with detachable Matheson and Dresser joint body 1, then freon communicated in air-conditioning system; When detachable Matheson and Dresser joint seat 2 disconnected with detachable Matheson and Dresser joint body 1, then freon disconnected in air-conditioning system, but can not cause freon to leak.Its working principle is: an end of spool 6 is positioned at the cone cavity of joint body 3 inside, the cone cavity is necessary in a this patent shape, have only an end of working as spool 6 in the cone cavity, spool 6 is subjected to the external force of thimble 7 to do the time spent, can carry out displacement in the cone cavity; Because of the cross section of cone cavity is inequality, and the cross section of spool 6 is constant, so along with after spool 6 moves, the gap occurred between spool 6 and awl cavity in the cone cavity, joint is inner here just forms perforation; And when detachable Matheson and Dresser joint body 1 separated with detachable Matheson and Dresser joint seat 2, then spool 6 was subjected to the elastic force effect of spring 4 and withstands, and formed sealing between spool 6 and cone cavity; Detachable Matheson and Dresser joint seat 2 comprises this seat of joint 8, and this seat of joint 8 inside are cavity, joint this 8 with a end that joint body 3 docks in thimble 7 is arranged, between thimble 7 and this seat of joint 8 seal ring 5 is arranged.When detachable Matheson and Dresser joint body 1 was connected with detachable Matheson and Dresser joint seat 2, thimble 7 dock with spool 6, and thimble 7 has active force spool 6 is pushed away toward detachable Matheson and Dresser joint body 1 inner chambers, formed the gap thereby make between spool 6 and cone cavity, and the formation perforation.
