Abstract
The utility model relates to an automobile air-conditioning direction guiding tube. Only nuts are arranged on the existing automobile air-conditioning direction guiding tube and are connected with an outer tube, although the connection stability is good, the sealing property is poor; and in the installation process, due to the fact that the nuts are directly arranged on the direction guide tube in a sleeved mode without any limitation, the nuts slide easily, the installation is affected, and the assembling efficiency is caused to be low. The automobile air-conditioning direction guiding tube comprises a tube body, and is characterized in that a plurality of O-shaped grooves are formed in the position close to the end portion of the tube body, O-shaped sealing rings are arranged on the O-shaped grooves in a sleeved mode, and a connecting nut is further arranged in the positions close to the end portion of the tube body. According to the automobile air-conditioning direction guiding tube, the sealing rings are arranged on the direction guiding tube, the direction guiding tube and the outer tube can be directly connected in an inserted mode conveniently, and the connection stability is increased. The arranged sealing rings are also capable of effectively improving the sealing property and solving the shortcoming existing in the prior art. Limiting and blocking rings are arranged on the tube body to prevent the connecting nut from sliding leftwards and rightwards and from affecting the installation, and the installation efficiency is improved.
Description
Technical field
The utility model relates to a kind of connection pipe fitting of car air conditioner, especially a kind of car air conditioner guide pipe.
Background technique
On the guide pipe of existing car air conditioner nut only is set and is connected with outer tube, though stable connection is good, seal not good; When installation process, because nut directly is nested with on guide pipe, without any restriction, the impact of sliding is easily installed, and causes efficiency of assembling on the low side.
The model utility content
The utility model provides a kind of car air conditioner guide pipe for above-mentioned defective, and is easy for installation, is connected reliably with outer tube, and sealing is good.
For this reason, the utility model is taked following technological scheme, a kind of car air conditioner guide pipe, comprise body, it is characterized in that described body closes on end position and has a plurality of " O " shape groove, all be nested with " O " shape seal ring on described " O " shape groove, close on end position on the described body and also be nested with a connection nut.
The inside portion that is positioned at " O " shape groove on the described body forms the back-up ring that limited connection nut moves outward.
Described attaching nut's rear portion Formation cross-section is circular reinforced layer.
The utility model arranges seal ring at guide pipe, is connected with outer tube card edge type but be convenient to guide pipe, has strengthened connection reliability.The also effectively lift-off seal of seal ring that arranges solves the defective that prior art exists.Spacing back-up ring is set on the body prevents that attaching nut's impact that horizontally slips from installing erection ﹠ lift efficient.
Description of drawings
Fig. 1 is the structural representation of model utility.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of car air conditioner guide pipe as shown in Figure 1 comprises body 1, and body 1 closes on end position and has a plurality of " O " shape groove, all is nested with " O " shape seal ring 3 on " O " shape groove, closes on end position on the body 1 and also is nested with a connection nut 2.The inside portion that is positioned at " O " shape groove on the body 1 forms the back-up ring 4 that limited connection nut moves outward, and attaching nut 2 rear portion Formation cross-section is circular reinforced layer.
The utility model arranges seal ring at guide pipe, is connected with outer tube card edge type but be convenient to guide pipe, has strengthened connection reliability.The also effectively lift-off seal of seal ring that arranges solves the defective that prior art exists.Spacing back-up ring is set on the body prevents that attaching nut's impact that horizontally slips from installing erection ﹠ lift efficient.
