Detailed Description
The application is described in further detail below with reference to fig. 1-3.
The embodiment of the application discloses a bicycle tire inflation and deflation nozzle. Referring to fig. 1 and 2, the inflation/deflation nozzle for a bicycle tire comprises a valve core 1 and a gas rod 2, wherein the valve core 1 is partially arranged in the gas rod 2 in a penetrating way, specifically, a first gas cavity 6 and a second gas cavity 7 are formed in the gas rod 2, the first gas cavity 6 is communicated with the second gas cavity 7, the diameter of the first gas cavity 6 is larger than that of the second gas cavity 7, and the valve core 1 is actually partially arranged in the first gas cavity 6 in a penetrating way. Thus, the larger diameter of the first air chamber 6 provides sufficient installation space for the valve core 1, while the second air chamber 7 only needs to have normal ventilation function, so that the smaller diameter thereof can enable the air rod 2 to have larger wall thickness, thereby improving the overall structural strength of the air rod 2.
Referring to fig. 1 and 3, a pair of reinforcing hoops 4 are sleeved on the outer wall of the air rod 2, the pair of reinforcing hoops 4 are respectively arranged at two ends of the air rod 2, specifically, annular grooves 21 are formed in the outer wall of the air rod 2 at the positions of the pair of reinforcing hoops 4, the annular grooves 21 are matched with the reinforcing hoops 4, a plurality of annular ribs 5 are uniformly formed on the groove walls of the pair of annular grooves 21, and the plurality of annular ribs 5 are distributed at intervals along the axial direction of the air rod 2. Therefore, after the reinforcing collar 4 is sleeved on the air rod 2, the reinforcing collar can be completely embedded into the annular groove 21, and is fixed in the annular groove 21 under the action of friction force of the annular ribs 5, so that the reinforcing collar can be tightened on the outer wall of the air rod 2, the overall structural strength of the air rod 2 is further improved, and expansion deformation of two ends of the air rod 2 is not easy to occur under the condition of large air pressure.
Referring to fig. 1 and 3, a base 3 is disposed at one end of the air rod 2 away from the valve core 1, and the base 3 is in threaded connection with the air rod 2, so as to increase the fixing area of the air rod 2 and the tire, and make the air rod 2 not easy to fall off after being fixed with the tire. In addition, the base 3 has the strengthening rib 8 towards one side of gas pole 2 in the peripheral department integrated into one piece of gas pole 2, and the strengthening rib 8 can promote the structural strength of gas pole 2 and base 3 junction, and when making gas pole 2 and base 3 be difficult for taking place to break and break away from, also can further reduce the possibility that gas pole 2 tip takes place the expansion deformation.
Referring to fig. 2, the valve core 1 is composed of a screw 11, a screw sleeve 12 and a nut 13, specifically, the screw 11 is inserted into the screw sleeve 12, both ends of the screw 11 extend out of the screw sleeve 12, the nut 13 is in threaded connection with one end of the screw 11 located outside the air rod 2, and an air hole 131 is formed in one side facing the screw sleeve 12, besides, a sealing assembly 9 is further arranged at one end of the screw 11 and the screw sleeve 12 located inside the air rod 2, the sealing assembly 9 is composed of a first sealing ring 91 and a second sealing ring 92, the first sealing ring 91 is sleeved on the screw 11, and the second sealing ring 92 is sleeved on the screw sleeve 12.
Therefore, when the valve core 1 is partially inserted into the gas rod 2, the second sealing ring 92 will abut against the inner wall of the gas rod 2, so as to realize the sealing connection between the valve core 1 and the gas rod 2, so that the gas is not easy to leak between the valve core 1 and the gas rod 2. When the air is inflated, the screw cap 13 is unscrewed, the screw 11 moves towards the inside of the air rod 2 under the driving of the screw cap 13, and drives the first sealing ring 91 to be far away from the end part of the screw sleeve 12, at the moment, the screw sleeve 12 is opened, external air can be pumped into the screw sleeve 12 through the air hole 131 by using tools such as an air pump, so that the air flows through the air rod 2 and enters the inflatable product, when the air is inflated, the screw cap 13 is screwed, the screw 11 moves towards the outside of the air rod 2 under the driving of the screw cap 13, and drives the first sealing ring 91 to be close to and finally abut against the end part of the screw sleeve 12, at the moment, the screw sleeve 12 is closed, and under the sealing effect of the first sealing ring 91, the air in the inflatable product is not easy to escape through the air rod 2 and the screw sleeve 12, so that the sealing performance of the whole air tap is improved.
Referring to fig. 2 and 3, the bicycle tire inflation/deflation nozzle further comprises a nozzle cap 10, the nozzle cap 10 is matched with the valve core 1, and the nozzle cap 10 is in threaded connection with the threaded sleeve 12, so that the part of the valve core 1 located outside the air rod 2 is protected, the valve core 1 is not easy to damage due to external factors when not in use, and the service life of the whole nozzle is prolonged.
The implementation principle of the inflation and deflation nozzle of the bicycle tire is that the pair of reinforcing hoops 4 are sleeved on the outer wall of the air rod 2, the pair of reinforcing hoops 4 are respectively arranged at two ends of the air rod 2, and the reinforcing hoops 4 can be hooped on the outer wall of the air rod 2 after being sleeved on the air rod 2, so that the overall structural strength of the air rod 2 is improved, and the two ends of the air rod 2 are not easy to expand and deform under the condition of high air pressure.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
