Abstract
It the utility model relates to a kind of two-tube pressing plate connection structure, including pressing plate, is set on the pressing plate there are two mounting hole, a pipe fitting is installed respectively in two mounting holes；The inner wall of the mounting hole is equipped with serrate slot, the pipe fitting and the mounting hole tight fit, and the pipe fitting is equipped with a heading structure after passing through the mounting hole, and the heading structure is close to the side of the pressing plate；Inner wall of the hole installing on pressing plate is equipped with serrate slot, and pipe fitting is pressed into serrate slot using expanding joint process, can prevent pipe fitting radial rotating, only one heading structure on pipe fitting saves tube material, and processing technology is simple, and cost of manufacture is lower.
Description
Technical field
The utility model relates to a kind of two-tube pressing plate connection structure, in particular to a kind of two-tube pressing plate for air conditioning for automobiles
Connection structure.
Background technique
A kind of existing two-tube pressing plate connection structure sets that there are two installations on the pressing plate as shown in Figure 1, include pressing plate
Hole, the inner wall of mounting hole be usually it is smooth, a pipe fitting is installed respectively in two mounting holes, is respectively equipped with two on pipe fitting
A heading structure, two heading structures are respectively arranged on the two sides of pressing plate, prevent pipe fitting axial float in mounting hole；Each pipe fitting
There are two heading structure, tube material, complex process are wasted, and still remains pipe fitting in mounting hole the problem of radial rotating.
In the prior art, the structure for also having single air-conditioner pipe to connect with pressing plate, the mounting hole on pressing plate are generally stepped hole,
The stepped hole includes aperture and macropore, is equipped with tooth socket in aperture inner wall, the processing of stepped hole needs individually removal material, increases
The expense of pressing plate, and pressing plate socket needs to do anti-error processing when pipe fitting expanded joint.
Utility model content
The utility model in view of the deficiency of the prior art, provides that a kind of structure is simple, and simple process is fabricated to
This low two-tube pressing plate connection structure.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of two-tube pressing plate connection structure, including pressure
Plate is set on the pressing plate there are two mounting hole, installs a pipe fitting respectively in two mounting holes；The inner wall of the mounting hole
Equipped with serrate slot, the pipe fitting and the mounting hole tight fit, the pipe fitting are equipped with a heading structure after passing through the mounting hole,
The heading structure is close to the side of the pressing plate.
Further, the pipe fitting is linked together with the pressing plate using expanding joint process.
Further, the heading structure is the pipe fitting by squeezing the annular protrusion formed.
The beneficial effects of the utility model are: the inner wall of the hole installing on pressing plate is equipped with serrate slot, will be managed using expanding joint process
When part is pressed into mounting hole, pipe fitting radial rotating can be prevented, only one heading structure on pipe fitting saves tube material, and
Processing technology is simple；Pressing plate is not required to processing sink hole, and cost of manufacture is lower, and pressing plate is distinguished without front and back sides, and when expanded joint is not required to anti-error
Processing, processing efficiency are higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of two-tube pressing plate connection structure in the prior art；
Fig. 2 is the structural schematic diagram of two-tube pressing plate connection structure in the utility model；
Fig. 3 is the structural schematic diagram of the utility model pressing plate；
In the accompanying drawings, list of designations represented by each label is as follows: 1, pressing plate, 1-1, mounting hole, 1-11, tooth form
Slot, 2, pipe fitting, 2-1, heading structure.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Fig. 2-Fig. 3, a kind of two-tube pressing plate connection structure, including pressing plate 1 sets that there are two installations on the pressing plate 1
A pipe fitting 2 is installed respectively in hole 1-1, two mounting hole 1-1；The inner wall of the mounting hole 1-1 is equipped with serrate slot 1-11,
The pipe fitting 2 and the mounting hole 1-1 tight fit, the pipe fitting 2 are equipped with a heading structure 2-1 after passing through the mounting hole 1-1,
The heading structure 2-1 is close to the side of the pressing plate 1.
The pipe fitting 2 is linked together with the pressing plate 1 using expanding joint process.
The heading structure 2-1 is the pipe fitting 2 by squeezing the annular protrusion formed.
When processing, usually pipe fitting 2 is clamped first with clamping, then, reaming is carried out to pipe fitting 2 using punch die, so that
Pipe fitting 2 is fixed together with pressing plate 1, finally, punch die continues to push, forms heading structure 2-1；Processing technology is very simple, raw
It is higher to produce efficiency.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
