Description

Technical Field

[0001] This invention relates to the field of tent technology, and more specifically to a tent air hose connection device. Background Technology

[0002] Tents are widely used in various activities such as tourism and leisure, serving as temporary shelters against wind, rain, and sunlight. In practical applications, to facilitate carrying and disassembly, tent tubing is used as a frame. During use, the tubing is inflated to achieve a certain rigidity, and then the individual tubing sections are assembled to form the tent frame structure. Currently, tent tubing is typically assembled using snap-fit ​​structures or webbing, but this method requires inflating each tubing individually before assembly, which is time-consuming and labor-intensive. Furthermore, air cannot circulate between the tubing sections, and the expansion coefficients of the individual tubing sections are not easily synchronized during inflation, affecting the coordination and stability of the tent frame structure. Summary of the Invention

[0003] The purpose of this invention is to provide a tent air hose connection device to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tent air hose connection device includes two sets of air valves respectively disposed on the inflation ports of two tent air hoses and a connecting pipe for connecting the two sets of air valves. Each air valve includes a valve body and a valve core. The valve body is provided with a valve cavity that extends vertically. The valve core is movably disposed on the valve body for closing the valve cavity. The end of the connecting pipe is detachably inserted into the bottom opening of the valve cavity. The connecting pipe is used to drive the valve core to open the valve cavity, so that the connecting pipe is connected to the tent air hose.

[0006] Preferably, the valve core includes a pin and a drive assembly. The pin is movably inserted into the top opening of the valve cavity, and the drive assembly is movably disposed within the valve cavity and connected to the pin. When the connecting tube is disengaged from the bottom opening of the valve cavity, the gas in the tent air pipe drives the top of the pin to close the top opening of the valve cavity. When the connecting tube is inserted into the bottom opening of the valve cavity, the connecting tube pushes the drive assembly upward, thereby causing the top of the pin to disengage from the top opening of the valve cavity.

[0007] Preferably, a guide tube is fixedly installed inside the valve cavity, and a guide post is provided at the bottom end of the umbrella nail, which is movably inserted into the guide tube. An anti-diving device is fixedly installed on the outer wall of the guide post and below the guide tube, and the outer diameter of the anti-diving device is larger than the diameter of the guide tube.

[0008] Preferably, the drive assembly includes a drive tube, a drive ring, and a spring. The drive tube is adapted to the valve cavity and is movably inserted into the valve cavity. The drive ring is fixedly connected to the bottom end of the drive tube, and the outer diameter of the drive ring is larger than the inner diameter of the valve cavity. The guide tube is fixedly connected to the inner wall of the valve cavity through a connecting rib. One end of the spring is connected to the guide tube, and the other end is connected to the inner wall of the drive tube. The top end of the drive tube has a clearance opening for the connecting rib to move.

[0009] Preferably, the drive tube has a spring slot in its wall, and a spring is elastically connected to the inner wall of the spring slot on the side closest to the umbrella nail. A first locking block is provided at the end of the spring that is away from the umbrella nail. The inner wall of the valve cavity has a movable groove for the first locking block to move up and down, and a second locking block matching the first locking block is provided at the end of the movable groove that is away from the umbrella nail.

[0010] Preferably, the anti-dangling device has a frustum-shaped structure and is elastic, and the upper wall of the guide tube has a slope that is adapted to the frustum-shaped structure for the anti-dangling device to be inserted into and pass through the guide tube. The end of the anti-dangling device is provided with an insertion post.

[0011] Preferably, the valve body includes an outer mounting tube and an inner valve seat. The outer mounting tube is disposed on the inflation port of the tent air pipe, and the inner valve seat is disposed in the upper cavity of the outer mounting tube. The connecting fitting includes a connecting tube and connectors disposed at both ends of the connecting tube. One end of the connector is detachably inserted into the lower cavity of the outer mounting tube by interference fit.

[0012] Preferably, the other end of the connector is provided with an annular insertion groove, the end of the connecting pipe is inserted into the annular insertion groove, and the other end of the connector is fitted with a nut. The nut is connected to the outer wall of the connector through a threaded structure, thereby squeezing the groove wall of the annular insertion groove and the pipe wall of the connecting pipe to fit tightly.

[0013] Preferably, the upper cavity inner wall of the outer mounting tube is provided with a mounting retaining ring, the outer wall of the inner valve seat is provided with a mounting groove for the mounting retaining ring to be engaged, the upper cavity inner wall of the outer mounting tube is provided with a sealing ring, and the outer wall of the connector is provided with a sealing groove for the sealing ring to be engaged.

[0014] Preferably, the lower end of the outer mounting tube extends outward to form a first mounting plate.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] This invention provides a tent air hose connector. Air valves are installed on the inflation ports of two sets of tent air hoses to be connected. During assembly, the hoses are connected via connecting fittings. The connector ends of the fittings are inserted into the valve chambers of the valves. A drive assembly drives the respective umbrella pins to detach from the top opening of the valve chamber, allowing gas to flow through the connecting fittings. During disassembly, the connectors are pulled out of the valve chambers. The drive assembly loses its support and moves downwards, causing the gas in the tent air hoses to drive the umbrella pins to seal the top opening of the valve chamber. This ensures the tent air hoses remain inflated during disassembly. When deflation is needed, the drive assembly can be manually pushed to detach the umbrella pins from the top opening of the valve chamber, achieving individual deflation. When in use, the tent air hoses can be assembled first, and then one of the tent air hoses can be inflated. The gas flows freely between the various tent air hoses through the connecting fittings and air valves, thus forming the tent frame. At the same time, when the tent air hoses are temporarily disassembled or the assembly structure is adjusted, the inflation port has an automatic sealing function, so there is no need to inflate again. The operation is convenient, quick and easy, saving time and effort. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] It should be noted that in this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element of this invention must have a specific orientation, and therefore should not be construed as a limitation of this invention. Example

[0024] Please refer to Figures 1 to 5 As shown, the present invention discloses a tent air pipe connection device, including two sets of air valves 1 respectively disposed on the inflation ports of two tent air pipes 3, and a connecting pipe 2 for connecting the two sets of air valves 1. The air valve 1 includes a valve body 11 and a valve core. The valve body 11 is provided with a valve cavity 111 that runs vertically through it. The valve core is movably disposed on the valve body 11 for closing the valve cavity 111. The end of the connecting pipe 2 is detachably inserted into the bottom opening of the valve cavity 111. The connecting pipe 2 is used to drive the valve core to open the valve cavity 111, so that the connecting pipe 2 is connected to the tent air pipe 3.

[0025] The valve core includes a parasol pin 12 and a drive assembly 13. The parasol pin 12 is movably inserted into the top opening of the valve cavity 111. The drive assembly 13 is movably disposed in the valve cavity 111 and connected to the parasol pin 12. When the connecting pipe 2 is disengaged from the bottom opening of the valve cavity 111, the gas in the tent air pipe 3 drives the top of the parasol pin 12 to close the top opening of the valve cavity 111. When the connecting pipe 2 is inserted into the bottom opening of the valve cavity 111, the connecting pipe 2 pushes the drive assembly 13 to move upward, thereby causing the top of the parasol pin 12 to disengage from the top opening of the valve cavity 111.

[0026] A guide tube 14 is fixedly installed inside the valve cavity 111. A guide post 15 is installed at the bottom end of the umbrella nail 12 and is inserted into the guide tube 14. An anti-dive 151 is fixedly installed on the outer wall of the guide post 15 and below the guide tube 14. The outer diameter of the anti-dive 151 is larger than the diameter of the guide tube 14 to prevent the guide post 15 from detaching from the guide tube 14.

[0027] The drive assembly 13 includes a drive tube 131, a drive ring 132, and a spring 133. The drive tube 131 is adapted to the valve cavity 111 and is inserted into the valve cavity 111 in a vertically movable manner. The drive ring 132 is fixedly connected to the bottom end of the drive tube 131, and the outer diameter of the drive ring 132 is larger than the inner diameter of the valve cavity 111. The guide tube 14 is fixedly connected to the inner wall of the valve cavity 111 through a connecting rib 141. One end of the spring 133 is connected to the guide tube 14, and the other end is connected to the inner wall of the drive tube 131. The inner wall of the drive tube 131 is provided with a stepped portion 134 for connecting the spring 133. The top end of the drive tube 131 is provided with a clearance opening 135 for the connecting rib 141 to move.

[0028] The drive tube 131 has a spring plate groove 136 on its tube wall. A spring plate 137 is elastically connected to the inner wall of the spring plate groove 136 on the side near the umbrella nail 12. A first locking block 138 is provided at the end of the spring plate 137 away from the umbrella nail 12. The inner wall of the valve cavity 111 has a movable groove 112 for the first locking block 138 to move up and down. A second locking block 113 matching the first locking block 138 is provided at the end of the movable groove 112 away from the umbrella nail 12. The drive tube 131 is inserted into the valve cavity 111 through the bottom opening of the valve cavity 111. The first locking block 138 and the second locking block 113 are respectively provided with right-angled trapezoidal structures, and the inclined surfaces of the trapezoids are arranged facing each other. When the drive tube 131 is inserted into the bottom opening of the valve cavity 111, the inclined surfaces of the first locking block 138 and the second locking block 113 come into contact and squeeze, thereby causing the drive spring 137 to deform and bounce inward in the spring groove 136. At this time, the drive ring 132 continues to be pushed until the first locking block 138 and the second locking block 113 miss each other. At this time, the first locking block 138 enters the valve cavity 111, the spring 137 returns to its deformed state, and the second locking block 113 abuts against the first locking block 138 to prevent the drive tube 131 from sliding out of the valve cavity 111.

[0029] The anti-dive 151 has a frustum-shaped structure and is elastic. The upper wall of the guide tube 14 has a slope that matches the frustum-shaped structure, allowing the anti-dive 151 to be inserted and pass through the guide tube 14. An insertion post 152 is provided at the end of the anti-dive 151. The outer diameter of the bottom end of the frustum of the anti-dive 151 is larger than the inner diameter of the bottom end of the guide tube 14, but smaller than the inner diameter of the top end of the guide tube 14. After the insertion post 152 is inserted into the guide tube 14, due to the frustum-shaped structure and elasticity of the anti-dive 151, the anti-dive 151 deforms under the pressure of the slope and passes through the guide tube 14. After the anti-dive 151 passes through the guide tube 14, the anti-dive 151 returns to its original shape. Since the outer diameter of the bottom end of the frustum of the anti-dive 151 is larger than the inner diameter of the bottom end of the guide tube 14, the anti-dive 151 is prevented from sliding out of the guide tube 14.

[0030] The valve body 11 includes an outer mounting tube 114 and an inner valve seat 115. The outer mounting tube 114 is installed on the inflation port of the tent air pipe 3, and the inner valve seat 115 is installed in the upper cavity of the outer mounting tube 114. The connecting pipe 2 includes a connecting tube 21 and connectors 22 installed at both ends of the connecting tube 21. One end of the connector 22 is detachably inserted into the lower cavity of the outer mounting tube 114 by interference fit. The outer mounting tube 114 is made of soft rubber, and the inner diameter of the lower end is equal to or smaller than the outer diameter of the connector 22. When the connector 22 is inserted into the lower cavity of the outer mounting tube 114, the interference fit prevents the connector 22 from falling off when no external force is applied.

[0031] The other end of the connector 22 has an annular insertion groove 221. The end of the connecting tube 21 is inserted into the annular insertion groove 221. The other end of the connector 22 is fitted with a nut 23. The nut 23 is connected to the outer wall of the connector 22 through a threaded structure, thereby pressing the groove wall of the annular insertion groove 221 and the tube wall of the connecting tube 21 tightly together. The connecting tube 21 is made of soft rubber. The inner wall height of the annular insertion groove 221 is greater than the outer wall height, and an insertion bevel 222 is formed at the top of the inner wall to insert into the port of the connecting tube 21. It cooperates with the outer wall to surround the end of the connecting tube 21. Under the pressure of the nut 23, the groove wall of the insertion groove 221 and the tube wall of the connecting tube 21 are tightly fitted, preventing the connector 22 from separating from the connecting tube 21.

[0032] The upper cavity of the outer mounting pipe 114 is provided with a mounting retaining ring 1141, the outer wall of the inner valve seat 115 is provided with a mounting groove 1151 for the mounting retaining ring 1141 to be inserted, the upper cavity of the outer mounting pipe 114 is provided with a sealing ring 1142, and the outer wall of the connector 22 is provided with a sealing groove 223 for the sealing ring 1142 to be inserted to improve the connection sealing performance.

[0033] The lower end of the outer mounting tube 114 extends outward to form a first mounting plate 116 for fixing the valve body to the inflation port of the tent air pipe 3. At the same time, the top outer wall of the inner valve seat 115 extends outward to form a sealing part 117, which covers the top surface of the outer mounting tube 114.

[0034] During assembly, the ends of the connectors 22 at both ends of the connecting pipe 2 are inserted into the valve chambers 111 of a set of air valves. The two connectors 22 are driven by the drive assembly 13 to disengage their respective umbrella pins 12 from the top opening of the valve chamber 111, allowing the gas in the two tent air pipes to flow through the pipe chambers of the connecting pipe 2. During disassembly, the connectors 22 are pulled out from the valve chambers 111 of the air valve 1. The drive assembly 13 loses its support and moves downward. The gas in the tent air pipe 3 drives the umbrella pins 12 to close the top opening of the valve chamber 111, so that the tent air pipe 3 can still remain in an expanded state during disassembly. When the tent air pipe 3 needs to be deflated, simply push the drive assembly 13 manually to drive the umbrella pins 12 to disengage from the top opening of the valve chamber 111 to achieve the effect of deflation.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
