Description

Technical Field

[0001] The present invention relates to the technical field of inflators, and in particular to an inflator connector. Background Art

[0002] An inflator connector, especially an inflator connector used to connect an inflator unit and capable of connecting to a tire valve. Generally, when inflating a tire, the inflator unit is connected to the tire valve through the inflator connector, and the inflator unit is started, so that the inflator can inject air into the tire.

[0003] The inflator connectors in the prior art mainly include a seat body, an airtight gasket, and a screw cap. The seat body is connected to the inflator unit, and an airtight gasket is provided inside the seat body. The screw cap is rotatably arranged at the end of the seat body, and a threaded section is formed on the inner side surface of the screw cap. When inflating a tire, the user can dock the seat body with the tire valve, and by rotating the screw cap, the threaded section in the screw cap is screwed with the thread on the tire valve, so that the tire valve can be airtightly abutted against the airtight gasket. Then, the user can start the inflator unit to inflate the tire.

[0004] By engaging the inflator connector with the tire valve in a threaded locking manner, the user has to rotate the screw cap until the inflator connector and the tire valve are airtightly engaged, which is not only inconvenient in operation but also takes more time during the locking process.

[0005] In addition, since the inflator connector in the prior art mainly rotates the screw cap to make the airtight gasket abut against the tire valve to achieve an airtight effect, when the user disassembles or locks the inflator connector and the tire valve, the seat body of the inflator connector will remain in a state of pressing against the air core of the tire valve, so that the gas inside the tire will continuously leak out during the process of the user disassembling or locking. Therefore, when the user inflates the tire to the standard air pressure, the gas inside the tire will leak out during the process of the user disassembling the inflator connector, and the inflator connector takes a long time to disassemble and lock, resulting in the air pressure inside the tire being lower than the standard pressure value after the user removes the inflator connector, thus causing a potential safety hazard for driving.

The inflator connector includes nozzle bodies 10a - 10c and a sliding sleeve 20.

[0046] Axially through ventilation channels 11 are formed inside the nozzle bodies 10a - 10c, and there are sealing washers 12 and at least one radially movable fastening portion 13a - 13d.

[0048] Among them, as Figure 3 , Figure 5 , Figure 7 shown, the inflator connector can make detailed changes to the structure of the nozzle bodies 10a - 10c, thereby presenting different embodiments. The following further describes the embodiments of different nozzle bodies 10a - 10c.

[0049] As Figure 2 , Figure 3 shown, in the first preferred embodiment of the inflator connector, the nozzle body 10a includes an assembly seat 14a, a connecting member 15a, and a fastening structure 16a.

The fastening structure 16a is arranged on the assembly seat 14a and abuts against the connecting member 15a. The fastening portion 13a is arranged on the fastening structure 16a and is located below the connecting member 15a. The sliding sleeve 20 is axially movably sleeved on the fastening structure 16a.

[0050] As Figure 4 , Figure 5As shown in the figure, in the second preferred embodiment of the inflator joint, the nozzle body 10b includes an assembly seat 14b, a connecting member 15b, a return spring 17, and a fastening structure 16a. The assembly seat 14b includes an assembly hole 141. The connecting member 15b is axially movable through the assembly hole 141 of the assembly seat 14b. The ventilation passage 11 penetrates through the connecting member 15b. The sealing gasket 12 is arranged at the bottom end of the connecting member 15b. The return spring 17 is arranged between the connecting member 15b and the assembly seat 14b, and the two opposite ends of the return spring 17 respectively abut against the connecting member 15b and the assembly seat 14b. The fastening structure 16a is arranged on the assembly seat 14b. The fastening portion 13a is arranged on the fastening structure 16a and is located below the connecting member 15b. The sliding sleeve 20 is axially movable and sleeved on the fastening structure 16a.

[0051] As Figure 7 shown, in the third preferred embodiment of the inflator joint, the nozzle body 10c includes an assembly seat 14c, a connecting member 15c, a return spring 17, an airtight gasket 19, and a fastening structure 16c. The connecting member 15c is axially movable and arranged in the assembly seat 14c. The ventilation passage 11 penetrates through the assembly seat 14c and the connecting member 15c. An active space 18 communicating with the ventilation passage 11 is formed between the assembly seat 14c and the connecting member 15c. The sealing gasket 12 is arranged at the bottom end of the connecting member 15c. The return spring 17 is arranged between the connecting member 15c and the assembly seat 14c, and the two opposite ends of the return spring 17 respectively abut against the connecting member 15c and the assembly seat 14c. The airtight gasket 19 is arranged between the connecting member 15c and the assembly seat 14c and is used to seal the active space 18. The fastening structure 16a is arranged on the assembly seat 14c. The fastening portion 13a is arranged on the fastening structure 16a and is located below the connecting member 15c. The sliding sleeve 20 is axially movable and sleeved on the fastening structure 16a.

[0052] In addition, as Figure 2 , Figure 8 , Figure 10 , Figure 11 shown, the inflator joint can further make detailed changes to the fastening structures 16a - 16c and present a variety of different embodiments. The following will further explain the embodiments of different fastening structures 16a - 16c respectively.

[0053] As Figures 2 to 7 shown, in the first to third preferred embodiments of the inflator joint of the present creation, the fastening structure 16a at least includes an elastic piece 161a and a fastening unit 162a. The fastening unit 162a is arranged at the end of the elastic piece 161a. The fastening portion 13a is formed on the fastening unit 162a. Among them, as Figure 6 shown, at least one pushing rib 163 is formed on the inner side of the elastic piece 161a. The pushing rib 163 is located at the end of the elastic piece 161a.

[0054] As shown in Figure 8 and Figure 9 In the fourth preferred embodiment of the inflator connector, the fastening structure 16b includes at least one elastic piece 161b. At least one pushing rib 163 is formed on the inner side of the elastic piece 161b. The pushing rib 163 is located at the end of the elastic piece 161b, and the fastening portion 13b is formed at the end of the elastic piece 161b.

[0055] As shown in Figures 10 to 12 In the fifth and sixth preferred embodiments of the inflator connector, the fastening structure 16c includes at least fastening units 162b and 162c. The fastening portions 13c and 13d are formed on the fastening units 162b and 162c. Among them, as shown in Figure 10 the fastening portion 13c and the fastening unit 162b may be integrally formed members; or as shown in Figure 12 the fastening portion 13d is additionally disposed inside the fastening unit 162c.

[0056] As shown in Figures 13 to 21 When a user uses the inflator connector, the user can connect the top of the nozzle body 10a-10c of the inflator connector to the inflator unit. Then, the user can directly hold and push down the sliding sleeve 20. While the nozzle body 10a-10c of the inflator connector is sleeved on the tire valve 30, the fastening portions 13a-13d are pushed by the sliding sleeve 20, so that the fastening portions 13a-13d can firmly fasten and fix the tire valve 30. Therefore, the user can quickly assemble or disassemble the inflator connector. Among them, when the nozzle body 10a-10c of the inflator connector is sleeved on the tire valve 30, the connectors 15a-15c of the nozzle body 10a-10c will abut against the valve core 31 of the tire valve 30, so that the ventilation passage 11 can communicate with the internal space of the tire valve 30, and the valve stem 32 of the tire valve 30 will abut against the sealing gasket 12 to achieve a sealing effect. Therefore, when the user fills the air pressure inside the tire to the standard air pressure, the user can quickly disassemble the inflator connector, so as to effectively avoid the leakage of the gas inside the tire, and then keep the air pressure inside the tire at the standard air pressure, thereby improving driving safety.

[0057] Among them, as shown in Figures 15 to 17 Taking the second preferred embodiment of the inflator connector as an example, before the inflator connector is used, the pushing rib 163 on the inner side of the elastic piece 161a abuts against the connector 15b of the nozzle body 10b. When the inflator connector is assembled to the tire valve 30, the connector 15b will be pushed by the valve stem 32 of the tire valve 30 and move relative to the assembly seat 14b of the nozzle body 10b, so that the connector 15b is separated from the pushing of the pushing rib 163 on the inner side of the elastic piece 161a. When the sliding sleeve 20 is pushed down, the elastic piece 161a can be pressed to make the fastening unit 162b fasten to the thread of the valve stem 32.

[0058] Through the arrangement of the pushing rib 163, when the inflator connector is sleeved on the tire valve 30, after the inflator connector extends into the tire valve 30 to a certain depth, the buckling portion 13a can be more firmly buckled on the thread of the valve stem 32. In addition, the return spring 17 provides a pushing effect, which can further improve the airtight effect between the inflator connector and the tire valve 30. Moreover, when the inflator connector is detached from the tire valve 30, the return spring 17 will reset the connecting member 15b, and the connecting member 15b will push against the pushing rib 163 after resetting, so that the elastic piece 161a can be surely reset, thereby avoiding the influence of the elastic fatigue of the elastic piece 161a on the smoothness of the connection of the inflator connector to the tire valve 30.

[0059] As Figures 13 to 17 shown, in the first to third preferred embodiments of the inflator connector, when the user pushes the sliding sleeve 20, the inner side surface of the sliding sleeve 20 will push against the elastic piece 161a of the buckling structure 16a, so that the buckling portion 13a located in the buckling unit 162a buckles the thread of the tire valve 30 to achieve the effect of buckling and fixing.

[0060] As Figure 18 、 Figure 19 shown, in the fourth preferred embodiment of the inflator connector, when the user pushes the sliding sleeve 20, the inner side surface of the sliding sleeve 20 will push against the elastic piece 161b of the buckling structure 16b, so that the buckling portion 13b located on the elastic piece 161b buckles the thread of the tire valve 30 to achieve the effect of buckling and fixing.

[0061] As Figure 20 、 Figure 21 shown, in the fifth preferred embodiment of the inflator connector, when the user pushes the sliding sleeve 20, the inner side surface of the sliding sleeve 20 will push against the buckling unit 162, so that the buckling portion 13c located on the buckling unit 162b buckles the thread of the tire valve 30 to achieve the effect of buckling and fixing.

[0062] In addition, when the inflator connector is assembled to the tire valve 30, the valve stem 32 of the tire valve 30 will abut against the sealing washer 12, and the flange 121 at the bottom end of the sealing washer 12 will extend into the valve stem 32. When inflating, the air pressure in the valve stem 32 of the tire valve 30 will make the flange 121 of the sealing washer 12 abut against the inner wall surface of the valve stem 32, which can further improve the airtight effect.

[0063] As Figure 22As shown, the inflator connector in the prior art mainly includes a base body 90, an airtight gasket 91, and a rotary buckle 92. The base body 90 is connected to the inflator unit, and the airtight gasket 91 is provided inside the base body 90. The rotary buckle 92 is rotatably arranged at the end of the base body 90, and a threaded section 93 is formed on the inner side surface of the rotary buckle 92. When inflating a tire, the user can dock the base body 90 with the tire valve 80 and screw the threaded section 93 in the rotary buckle 92 with the thread 81 on the tire valve 80 by rotating the rotary buckle 92, so that the tire valve 80 can be airtightly abutted against the airtight gasket 91. Then, the user can start the inflator unit to inflate the tire.

[0064] However, by joining the inflator connector and the tire valve 80 in a threaded locking manner, the user must rotate the rotary buckle 92 until the inflator connector and the tire valve 80 are airtightly joined, which is not only inconvenient in operation but also takes more time during the locking process.

[0065] In addition, since the current inflator connector mainly achieves an airtight effect by rotating the rotary buckle 92 to make the airtight gasket 91 abut against the tire valve 80, when the user disassembles or locks the inflator connector and the tire valve 80, the base body 90 of the inflator connector will remain in a state of pressing against the valve core 82 of the tire valve 80, so that the gas inside the tire will continuously leak out during the process of the user disassembling or locking. Therefore, when the user inflates the tire to the standard air pressure, the gas inside the tire will leak out during the process of the user disassembling the inflator connector, and the inflator connector takes a long time to disassemble and lock, resulting in the air pressure inside the tire being lower than the standard pressure value after the user removes the inflator connector, thus causing a potential safety hazard for driving.

[0066] In summary, the inflator connector mainly consists of a sliding sleeve 20 and the buckling parts 13a - 13d of the nozzle bodies 10a - 10c, enabling the user to directly assemble the inflator connector onto the tire valve 30 by pushing the sliding sleeve 20 and in a buckling manner. This not only effectively saves operation time but also has good operation convenience, and can effectively avoid the problem of gas leakage inside the tire when disassembling the inflator connector, thereby keeping the air pressure inside the tire at the standard air pressure and improving driving safety.

[0067] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those skilled in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious variations can be made, and if the performance or use is the same, they should all be regarded as belonging to the protection scope of the present invention.
