Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a high-air-tightness inflatable tent valve. Background Art

[0002] The inflatable tent valve, as the name implies, is a valve installed on the inflatable tent. This valve is mainly used for inflating and deflating the inflatable tent. When inflating, you need to use an air pump to inflate, and when deflated, you need to unplug the inflation one-way valve to quickly exhaust the air. However, when exhausting, you still need to forcefully insert the pulled-out one-way valve into the exhaust hole. Long-term use will lead to reduced sealing of the exhaust hole and air leakage, and the plugging and unplugging process is also very troublesome. In addition, a dedicated inflation port is required for inflation. If you forget to bring it or the air pump you carry is damaged, you cannot rely on other models of others for emergency. Therefore, this inflation method is very inflexible. For this reason, we propose a high airtightness inflatable tent valve. Utility Model Content

[0003] The main purpose of the utility model is to provide a high-air-tightness inflatable tent valve, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Furthermore, the mounting valve seat comprises an air guide tube, a spiral joint and a packaging seat, the front end of the air guide tube is fixedly connected with the spiral joint, and the packaging seat is fixedly mounted at the connection between the air guide tube and the spiral joint.

[0007] Furthermore, the inflation and deflation valve includes a valve sleeve, a rotating rod, an exhaust hole, a spiral groove, a sealing gasket and a one-way valve core. The outer surface of the valve sleeve is fixedly installed with a rotating rod at two equal parts, the arc surface of the valve sleeve is provided with exhaust holes at six equal parts, the inner side of the valve sleeve is provided with a spiral groove near one end, the one-way valve core is fixedly installed in the middle of the inner side of the valve sleeve, and a sealing gasket is embedded in the spiral groove.

[0008] Furthermore, the spiral groove is connected to the outside through the exhaust hole, and the gas charging and discharging valve is screwed on the spiral joint through the spiral groove and connected to the mounting valve seat.

[0009] Furthermore, the emergency inflation structure includes a rubber outer plug, an inflation bell, a rubber ring, a rubber inner plug and a storage hole. An air inlet hole is opened in the middle of the rubber outer plug, the front port of the air inlet hole is fixedly connected to the inflation bell, a rubber ring is fixedly installed on the edge of the front port of the inflation bell, the rear port of the air inlet hole is sealed with a rubber inner plug, and a storage hole is opened at the front end of the rubber inner plug.

[0010] Furthermore, the emergency inflation structure seals the port of the inflation and deflation valve by inserting a rubber outer plug into the front port of the valve cylinder sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the inflatable tent valve only needs to slightly twist the valve sleeve to make the end of the spiral joint separate from the sealing pad when deflation, so that the gas in the inflatable tent can be quickly discharged to the outside from the exhaust hole, and can be tightened after discharge. The operation is simple and convenient, and when the special air pump is forgotten to be brought or the special air pump is damaged and cannot work normally, emergency inflation can be carried out with the help of other people's air pumps of different models, which makes it more adaptable and more flexible to use.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] Embodiment 1:

[0019] like Figure 1-3As shown, a high air-tightness inflatable tent valve comprises a mounting valve seat 1, an air charging and discharging valve 2 and an emergency air-charging structure 3, wherein the port of the mounting valve seat 1 is spirally connected with the air charging and discharging valve 2, and the port of the air charging and discharging valve 2 is sealed with the emergency air-charging structure 3;

[0020] The installation valve seat 1 includes an air guide tube 101, a spiral joint 102 and a packaging seat 103. The front end of the air guide tube 101 is fixedly connected with the spiral joint 102. The packaging seat 103 is fixedly installed at the connection between the air guide tube 101 and the spiral joint 102. The installation valve seat 1 is sealed and pressed with the tent through the packaging seat 103; the charging and discharging valve 2 includes a valve sleeve 201, a rotating rod 202, an exhaust hole 203, a spiral groove 204, a sealing gasket 205 and a one-way valve core 206. The rotating rod 202 is fixedly installed at the two-half position of the outer surface of the valve sleeve 201, and the six-half position of the arc surface of the valve sleeve 201 are provided with exhaust holes 203. A spiral groove 204 is opened on the inner side of the valve sleeve 201 near one end. A one-way valve core 206 is fixedly installed in the middle of the inner side of the valve sleeve 201, and a sealing gasket 205 is embedded in the spiral groove 204; the spiral groove 204 passes through the exhaust hole 20 3 is connected to the outside world, the charging and discharging valve 2 is screwed on the spiral joint 102 through the spiral groove 204 and connected to the mounting valve seat 1; the emergency inflation structure 3 includes a rubber outer plug 301, an inflation bell mouth 302, a rubber ring 303, a rubber inner plug 304 and a storage hole 305, an air inlet hole is opened in the middle of the rubber outer plug 301, the front end of the air inlet hole is fixedly connected with the inflation bell mouth 302, and the front end edge of the inflation bell mouth 302 is fixedly installed with a rubber ring 303, wherein the inflation bell mouth 302 and the rubber ring 303 can be plugged into the storage hole 305 for storage by the user when not in use, wherein the inflation bell mouth 302 is made of airtight material, the rear end of the air inlet hole is sealed with a rubber inner plug 304, and the front end of the rubber inner plug 304 is opened with a storage hole 305; the emergency inflation structure 3 seals the charging and discharging valve 2 by plugging the rubber outer plug 301 into the front end of the valve cylinder sleeve 201.

[0021] It should be noted that the utility model is a high-air-tightness inflatable tent valve. When in use, the rubber outer plug 301 is unplugged, and the dedicated air pump port is plugged into the valve sleeve 201 of the same size for docking and inflation. After inflation, the rubber outer plug 301 can be plugged into the port of the valve sleeve 201 for further sealing, so that the inflatable tent valve has higher air-tightness. When exhaust is required, the user can directly screw the valve sleeve 201 to loosen the spiral groove 204 on the spiral joint 102. At this time, the port of the spiral joint 102 is separated from the sealing pad 205, so that the gas in the inflatable tent will quickly enter the exhaust hole 203 from the air guide tube 101 and be discharged to the outside. The air can be quickly deflated without completely removing the valve sleeve 201, making the exhaust operation simpler and more convenient. In addition, when inflating, if the specially equipped air pump is forgotten to be brought or damaged, other models of air pumps can be used with the help of others. When in use, the rubber inner plug 304 in the rubber outer plug 301 is removed, and then the rubber outer plug 301 is inserted into the port of the valve sleeve 201, and then the air pump inflation port is inserted into the inflation bell mouth 302. At this time, the rubber ring 303 will tighten and self-seal around the inflation port, and the inflation bell mouth 302 port can be pressed by hand to prevent it from falling off, so that emergency inflation of multiple interfaces can be achieved.
