Description
Technical field
This utility model relates to air-conditioning pipe fitting docking structure, and weldering exempted from by the air conditioning for automobiles pipe fitting of a kind of band pressing plate joint
Connect docking structure.
Background technology
Connection between each pipe fitting in air conditioning system for vehicle, uses pressing plate joint docking form, at present, this kind of docking shape mostly
Formula typically uses the form of two pressing plate docking to be fixed by two pipeline joints, needs pressing plate and a wherein pipe fitting during docking
Fixed by gas brazing, and soldering tech requires height to workman, and welding efficiency is low, be easily generated rosin joint, solder skip, trachoma etc. and lack
Fall into, there is the risk of leakage, production relatively costly, inconvenient operation.
Summary of the invention
Goal of the invention: the problems referred to above that this utility model exists for existing car air-conditioner pipe fitting joint structure, it is provided that
Butt welding structure exempted from by kind production efficiency height, good airproof performance, air conditioning for automobiles pipe fitting with low cost.
To achieve these goals, this utility model have employed following technical scheme: the automobile of a kind of band pressing plate joint
Butt welding structure exempted from by air-conditioning pipe fitting, including pressing plate joint one, pressing plate joint two, pipe fitting one and pipe fitting two, described pressing plate joint
One is provided with pipe fitting connecting hole one and bolt positioning hole, and pipe fitting connecting hole one one end is provided with locating slot, described pipe fitting one and pipe
Part connecting hole one expanded joint connects, and it is first that pipe fitting one end is provided with the connection matched with locating slot, and described pressing plate joint two sets
Being equipped with pipe fitting connecting hole two and screwed hole, described pipe fitting two end is provided with union joint two, union joint two and pipe fitting connecting hole two
Expanded joint connect, union joint two inner circle be connected first cylindrical matched in clearance, connect first cylindrical and be provided with O RunddichtringO, by O type
Sealing ring realize union joint two, connect first between sealing.
Further, described pipe fitting connecting hole one, pipe fitting connecting hole two inwall are uniformly distributed along the circumference some serrate slots.
Further, described serrate slot cross sectional shape is triangular in shape.
Compared with existing air-conditioning pipe fitting docking structure, of the present utility model have the advantage that
(1) pipe fitting is connected with pressing plate joint expanded joint, compares existing being welded and fixed, and simple to operate, pipeline production efficiency is higher；
(2) the pipe fitting connecting hole inwall of pressing plate joint arranges serrate slot, can effectively prevent pipe fitting relative with nipple
Rotate；
(3) use the docking structure exempting to weld, eliminate the leakage hidden danger caused because of weld defect；
(4) gas brazing pollution to environment is eliminated, more environmentally-friendly；
(5) can omit leak detection operation, pipeline energy consumption is lower, cost-effective.

Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is done and further explain.
As shown in Figures 1 to 3, butt welding structure exempted from by the air conditioning for automobiles pipe fitting of a kind of band pressing plate joint of the present utility model,
Including pressing plate joint 1, pressing plate joint 22, pipe fitting 1 and pipe fitting 24.
Described pressing plate joint 1 is provided with pipe fitting connecting hole 1 and bolt positioning hole 7, described pipe fitting connecting hole 1 inwall
Be uniformly distributed along the circumference some serrate slots 12, and described serrate slot 12 cross sectional shape is triangular in shape, and pipe fitting connecting hole 1 one end is provided with fixed
Position groove 6.Described pipe fitting 1 is connected with pipe fitting connecting hole 1 expanded joint, and pipe fitting 1 end is provided with the company matched with locating slot 6
Joint 1, first 8 cylindricals of described connection are provided with O RunddichtringO 13.
Described pressing plate joint 22 is provided with pipe fitting connecting hole 29 and screwed hole 10, described pipe fitting connecting hole 29 inwall edge
The some serrate slots of circumference uniform distribution 12, described pipe fitting 24 end is provided with union joint 2 11, union joint 2 11 and pipe fitting connecting hole two
9 expanded joints connect, union joint 2 11 inner circle be connected first 8 cylindrical matched in clearance.By the compression of O RunddichtringO 13, real
Existing union joint 2 11, the sealing connected between first 8.
When pipe fitting 1 and pipe fitting 24 docking, first pass through tube expander by swollen for pipe fitting 1 pipe being firmly scheduled on pressing plate joint 1
