Abstract
The invention discloses a vehicle air condition dust cap and relates to the technical field of manufacture of vehicle air conditioners. The vehicle air condition dust cap comprises a dust cap body and a seal gasket arranged in the dust cap body, wherein the top end of the dust cap body is connected with one end of a connection band, the other end of the connection band is connected with a charging valve, a groove is formed in the top end of the dust cap body, a circular ring is arranged at each of two ends of the connection band, a plastic sheet which is of a tooth type trip prevention structure is arranged in each circular ring hole, one circular ring hole of the connection band is sleeved by the groove of the dust cap body, and the other circular ring hole is sleeved by the bottom of a valve body of the charging valve. According to the vehicle air condition dust cap, the problem that fine foreign matters such as dust are accumulated on the charging valve due to the fact that dust caps are prone to be lost can be solved.
Description
Technical field
The present invention relates to vehicle air conditioner manufacturing technology field, especially a kind of dust cap for charging valve on car air-conditioner high low pressure pipeline.
Background technique
Existing car air conditioner is generally provided with charging valve on air-conditioning high low pressure pipeline, as the filled interface of air-conditioning refrigerant and the interface of air-conditioning system Pressure testing; For the deposition of foreign material such as anti-sealing, dust are filling on valve port, while not using charging valve at ordinary times, be that dustproof cap is being filled on mouth; Dust cap is made up of dust cap body and sealing gasket, is two parts that independently separate with charging valve, and both are fixed together by being threaded.There is following problem in the dust cap of this form: 1, because dust cap is less, in the time giving air-conditioning system charging refrigerant or detect air-conditioning system pressure, dust cap need to be pulled down, in charging refrigerant or the process of detection because not using it, be shelved on one side, be easy to cause loss; 2, because dust cap is twisted not tightly, or vibration in vehicle using process easily causes loose or dislocation and loses; 3, do not belong to the conventional accessory of vehicle maintenance because of dust cap; be difficult to buying on the market once lose; because causing charging valve, the loss of dust cap lacks proofing dust and protecting; dust easily accumulates in and fills on valve port; in the time of upper once charging refrigerant or detection air-conditioning system pressure; be easy to bring in air-conditioning system accumulating in the dust or other small foreign body that fill on valve port, cause the system failure.
Summary of the invention
The object of this invention is to provide a kind of car air-conditioner dust cap, it can solve this car air-conditioner dust cap the easy loss of dust cap and cause the small foreign bodies such as dust to be easy to accumulate in the problem filling on valve port.
In order to address the above problem, the technical solution used in the present invention is:
This car air-conditioner dust cap, includes dust cap body, is arranged on the sealing gasket in described dust cap body, and described dust cap body top is connected with one end of connecting band, and the other end of described connecting band is connected with charging valve.
In above technological scheme, further scheme is: described dust cap body top offers groove; Described connecting band is that two ends respectively have an annulus, has the plastic sheet of flute profile disconnecting prevention structure in annulus hole; An annulus borehole jack of connecting band enters in the groove of dust cap body, and another annulus borehole jack enters charging valve valve body bottom.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention arranges the connecting band that connects both between dust cap body and charging valve, makes charging valve and dust cap form a relative entirety, and no matter dust cap takes off uses or is come off by vibration, and it is connected on charging valve all the time, is difficult to lose; User finds when it comes off to be twisted in time, has avoided cannot causing the small foreign bodies such as dust filling gathering on valve port to filling valve port proofing dust and protecting in time because of the loss of dust cap.
2, the present invention is simple in structure, easily manufactures, with low cost.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Fig. 3 is the schematic diagram of the present invention while using state.
Schematic diagram when Fig. 4 is non-working condition of the present invention.
Number in the figure is expressed as: 1, connecting band; 2, sealing gasket; 3, dust cap body; 4, charging valve.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
The car air-conditioner dust cap of Fig. 1 and Fig. 2, includes dust cap body 3, is arranged on the sealing gasket 2 in dust cap body 3: dust cap body 3 tops are connected with one end of connecting band 1, and the other end of connecting band 1 is connected with charging valve 4.Dust cap body 3 tops offer groove; Connecting band 1 is similar is dumbbell shaped structure, connecting band 1 is that two ends respectively have an annulus, in annulus hole, have the plastic sheet of flute profile disconnecting prevention structure, an annulus borehole jack of connecting band 1 enters in the groove of dust cap body 3, is rotatably stuck in groove and is connected as a single entity with dust cap body 3; Another annulus borehole jack of connecting band 1 enters charging valve 4 valve body bottoms, also rotatable with respect to charging valve 4 valve bodies.
Fig. 3 is the schematic diagram of the present invention while using state; Dust cap body 3 is screwed on the filled mouth of charging valve 4, sealing gasket 2 is adjacent to the filled mouth of charging valve 4 under the pressure-acting of dust cap body 3, the filled mouth of charging valve 4 is under the protection of dust cap body 3 and sealing gasket 2, and the small foreign bodies such as dust cannot enter filled valve port and cause gathering of dirt.
Schematic diagram when Fig. 4 is non-working condition of the present invention; In the time will giving air-conditioning system charging refrigerant or detect air-conditioning system pressure, dust cap body 3 directly can be backed out to relieving, needn't consider its part of depositing, after charging refrigerant or detection complete, directly screwed back.Even because dust cap body is twisted not tightly, or vibration in vehicle using process causes loose or dislocation, and because there being connecting band that charging valve is connected with dust cap body, dust cap body hangs on charging valve all the time also can not be lost; When discovery comes off, screwed back in time charging valve.
