Abstract
The utility model discloses a fixing structure between vehicle air conditioner plastic members comprising two plastic members, which are disposed in the vehicle air conditioner, and are cooperated with each other. The two plastic members are provided with opposite through holes, in which are disposed expansion screw holes. Studs are tightly inserted in the expansion screw holes in a screwed manner. By adopting the tightly-screwed stud structure, only the through holes are required to be disposed in the two cooperated plastic members, and therefore the assembly structure is simple, the arrangement, the installation, and the dismounting are convenient, the structure is not easy to loosen after being fastened, and the production costs are low.
Description
Technical field
The utility model relates to automobile air conditioning technology field, especially relates to the fixed structure between a kind of car air conditioner working of plastics.
Background technique
At present, the main assembly structure between car air conditioner working of plastics is: after a kind of screw column assembling of passing through via hole and another working of plastics on a working of plastics, then by screw urgent fixing together; Another kind matches fixing with draw-in groove by back-off, working of plastics one side is provided with back-off opposite side and is provided with draw-in groove, and two coordinate working of plasticss to allow back-off slip in draw-in groove by extruding, and it is fixed together.
After the long-term use of existing assembly structure, the cooperation between working of plastics is easily loosening; And assembly structure needs enough spaces, is not easy to design arrangement, installing/dismounting inconvenience.
Model utility content
Not enough for prior art, technical problem to be solved in the utility model is to provide the fixed structure between a kind of car air conditioner working of plastics, to reach easy installation and removal and the fastening rear object that is difficult for getting loose.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: the fixed structure between a kind of car air conditioner working of plastics, comprise and be located at the two plastic parts cooperatively interacting in car air conditioner, described two plastic parts is provided with relative via hole, in via hole, be provided with expansion screw, described expansion screw inward turning is tightly inserted with screw column.
Further, the end of described expansion screw is provided with fluting.
The end edge of described expansion screw is taper.
Described expansion screw head is provided with the groove suitable with screw column head.
The internal diameter of described via hole is identical with the external diameter of expansion screw.
The utility model compared with prior art, has the following advantages: by plastics screw tightened-up structure, on two working of plasticss that match, only need be provided with via hole, assembly structure is simple, is convenient to arrange and installing/dismounting, and fastening rear being difficult for becomes flexible, and cost of production is low.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is that the utility model screw column coordinates schematic diagram with expansion screw.
Fig. 2 is the utility model expanding screw hole structure schematic diagram.
Fig. 3 is the utility model screw column structural representation.
In figure: 1. screw column, 2. expansion screw, 21. flutings, 22. grooves, 23. tapers.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, fixed structure between this car air conditioner working of plastics, comprise and be located at the two plastic parts cooperatively interacting in car air conditioner, a working of plastics is provided with via hole I, another working of plastics is provided with via hole II, via hole I is relative with via hole II position, in relative via hole I and via hole II, is inserted with expansion screw 2, screws and be inserted with screw column 1 in expansion screw 2.The internal diameter of via hole is identical with the external diameter of expansion screw 2, is difficult for getting loose after fastening.
Preferably, the end of expansion screw 2 is provided with fluting 21, and the end edge of expansion screw 2 is taper 23, is convenient to be arranged in via hole, increases work efficiency.
On expansion screw 2 heads, be provided with the groove 22 suitable with screw column head, after assembling, the head of screw column sinks in the head of expansion screw, and the head of expansion screw is fitted on working of plastics, attractive in appearance neat, does not take up room.
Screw column is working of plastics, with working of plastics, replaces metalwork, because the quantity that fixed structure is used is more, greatly reduces cost of production.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
