Description

Technical Field

[0001] This invention relates to the field of inflation valve technology, and in particular to an inflation valve device with dual air pipe joints. Background Technology

[0002] In the field of inflation valve technology, traditional inflation valve devices are mostly equipped with only a single air pipe connector, which is difficult to meet the needs of scenarios that require simultaneous inflation of two different objects, such as inflation of dual-bladder equipment or synchronous air supply of multi-cavity structures. This results in low operating efficiency, frequent replacement of air pipe connections, and cumbersome and time-consuming operation.

[0003] Meanwhile, some existing multi-connector inflation valve devices have a fixed connection structure between the connector and the valve body, which makes it impossible to flexibly adjust the connector angle according to the actual installation space and air pipe routing. This can easily lead to air pipe twisting or bending, affecting the smooth flow of gas and even causing air pipe damage.

[0004] In addition, the valve core control structure design of traditional inflation valves is not reasonable enough, and the matching precision between moving parts is insufficient. During inflation, problems such as poor sealing and gas leakage are prone to occur, which reduces the reliability of inflation operations.

[0005] Moreover, the connection stability between the connector and the connecting parts is not good. After long-term use or after being subjected to slight external impact, it is easy to loosen, which further aggravates the risk of leakage and cannot meet the requirements of high precision and high stability inflation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, by setting a connecting component at the front end of the valve body shell, wherein the upper end of the connecting head of the connecting component is rotatably connected to the upper ring and the first connector via a base ring and a middle ring, and the front end of the connecting head is also connected to a connecting pipe, forming a double air pipe joint structure, effectively solves the problem that the single connector of the traditional air valve cannot meet the synchronous air inflation of two objects, eliminating the need for frequent air pipe connection replacement and greatly improving the air inflation operation efficiency. At the same time, the middle ring is rotatably engaged with the first convex groove of the base ring and the second convex groove of the upper ring via a first convex rod, and the first connector is rotatably connected to the second convex groove via a second convex rod. A plug assembly is rotatably installed on the left side of the connecting pipe, so that the angle of both connectors can be flexibly adjusted to adapt to different installation spaces and air pipe directions, avoiding air pipe twisting and bending, and ensuring smooth gas flow.

[0022] 2. In this invention, the upper and lower end faces of the valve body shell are fixed with sealing covers by screws. The magnetic iron sheet of the lower sealing cover is tightly attached to the mounting plate. On the one hand, the sealing cover achieves reliable sealing of the internal structure of the valve body shell, solving the problem of poor sealing and easy leakage in traditional air-filling valves. On the other hand, the magnetic attraction of the magnetic iron sheet, combined with the screw fixing, improves the connection stability between the valve body shell and the mounting plate. At the same time, it facilitates the quick positioning, installation, disassembly and maintenance of the valve body shell, solving the problems of inconvenient valve body installation and disassembly and poor sealing performance mentioned in the background art.

[0023] 3. In this invention, the installation position of the electromagnetic coil is defined inside the valve body shell by a first baffle and a second baffle. A movable iron core is slidably installed on the outer side of the push rod inside the electromagnetic coil. The movable iron core is connected to the movable push rod by a movable spring. An iron core spring is set between the blocking plate at one end of the movable push rod and the second baffle. The blocking plate is connected to the movable pin through an mounting head. The movable pin is slidably installed in the through hole of the valve body shell. This structure enables the movable iron core, movable push rod, blocking plate, and movable pin to form a linkage. The precise extension and retraction of the movable pin is achieved by opening and closing the electromagnetic coil, thereby realizing reliable on / off control of the inflation channel. This improves the accuracy and stability of valve core control and solves the problems of insufficient valve core fitting accuracy and unreliable on / off control in traditional inflation valves, further ensuring the sealing and reliability of inflation operations. Moreover, since the second baffle has a U-shaped groove, the drive device inside the valve body shell can be quickly disassembled and assembled, thus enabling rapid inspection and replacement of the valve body.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 12 The present invention provides a technical solution:

[0044] An inflation valve device with dual air pipe connectors includes a mounting plate 1. The mounting plate 1 is specially treated to magnetically connect with subsequent magnetic iron plates 201. Two valve body shells 2 are positioned above the mounting plate 1. Sealing caps 203 are fixedly mounted to the four corners of the upper and lower end faces of each valve body shell 2 using screws. Grooves are formed on the lower end faces of the two sealing caps 203, and magnetic iron plates 201 are magnetically fixedly mounted inside these grooves. Therefore, the valve body shells 2 are fixedly mounted to the upper end face of the mounting plate 1 via the magnetic iron plates 201. Figure 1 and Figure 2 As shown.

[0045] A wiring hole 202 is fixedly installed on the left edge of the valve body housing 2, while a first baffle 204 is fixedly installed on the left side inside the valve body housing 2, and a second baffle 206 is fixedly installed on the right side inside the valve body housing 2. Figure 4 As shown.

[0046] A junction box 205 is fixedly installed on the left side of the first baffle 204. It should be noted that the junction box 205 and the plug hole 202 are in a through state, and external lines can be fixedly connected to the junction box 205 through the plug hole 202.

[0047] Then, an electromagnetic coil 207 is slidably installed on the right side of the first baffle 204, and the left side of the electromagnetic coil 207 is tightly fitted to the right side of the first baffle 204. A push rod 208 is installed inside the left end of the electromagnetic coil 207, and a movable iron core 209 is slidably installed on the outer circumferential surface of the right end of the push rod 208. A movable spring 210 is fixedly installed inside the movable iron core 209, that is, at the right end of the push rod 208. A movable push rod 211 is fixedly installed at the right end of the movable spring 210, and the left end of the movable push rod 211 is fixedly installed on the movable iron core. Inside the right end of 209, a blocking plate 212 is fixedly installed on the right end of the movable top rod 211. A core spring 213 is fixedly installed between the left end of the blocking plate 212 and the second baffle 206. An installation head 215 is fixedly installed in the middle of the right end of the blocking plate 212. Then, a through hole 218 is opened from the right end to the inside of the valve body shell 2. A movable pin 216 is slidably installed inside the through hole 218. A T-shaped groove 217 is opened from the upper end face to the lower end face of the left end of the movable pin 216. The installation head 215 and the T-shaped groove 217 are slidably connected.

[0048] It should be noted that there is an electrical connection between the electromagnetic coil 207 and the junction box 205.

[0049] Therefore, during use, when an external power source is connected to the junction box 205 through the plug hole 202, the electromagnetic coil 207 is energized to generate a magnetic field. This magnetic field acts on the movable iron core 209, causing it to overcome the resistance of the iron core spring 213 and slide to the left.

[0050] The movable iron core 209 moves together with the movable top rod 211, causing the blocking plate 212 to move inside the T-slot 217 with the mounting head 215, and the movable pin 216 moves synchronously during the movement.

[0051] The movable pin 216 moves axially within the through hole 218, thereby controlling the opening and closing of the airflow passage. When the power is off, the iron core spring 213 moves synchronously with the blocking plate 212, and during the movement, it resets the movable push rod 211. The movable push rod 211 and the blocking plate 212 return to their initial positions. At this time, the movement of the blocking plate 212 will cause the movable pin 216 to move synchronously, ensuring that the valve device is reliably closed.

[0052] A connecting component 3 is fixedly installed on the front end face of the valve body housing 2. The connecting component 3 includes a connecting head 301, the rear end of which is fixedly installed on the front end face of the valve body housing 2. A three-way pipe 302 is fixedly installed inside the connecting head 301. The rear end of the three-way pipe 302 communicates with the through hole 218 of the valve body housing 2, and a movable pin 216 is slidably installed inside the three-way pipe 302. Furthermore, the upper middle part of the three-way pipe 302 extends to the outside of the connecting head 301. Figure 6 As shown.

[0053] A base ring 303 is fixedly installed at the upper middle part of the three-way pipe 302. A first convex groove 304 is fixedly installed on the top of the base ring 303. A middle ring 305 is rotatably installed at the upper end of the base ring 303. A first convex rod 306 is fixedly installed at both the upper and lower ends of the middle ring 305. The lower first convex rod 306 is rotatably installed inside the first convex groove 304. Then, an upper ring 307 is rotatably installed at the upper end of the middle ring 305. A second convex groove 308 is opened on both the upper and lower end faces of the upper ring 307. The upper first convex rod 306 is rotatably installed inside the second convex groove 308. A first connector 310 is rotatably installed at the upper end of the upper ring 307. A second convex rod 309 is fixedly installed on the lower end face of the first connector 310. The second convex rod 309 is rotatably installed inside the upper second convex groove 308. Figure 7 As shown.

[0054] During use, the user can manually rotate the middle ring 305 or the upper ring 307 to allow the first convex rod 306 to rotate within the second convex groove 308, thereby adjusting the orientation of the first connector 310 for easy and flexible connection to the external air pipe. Simultaneously, the second convex rod 309 rotates freely within the second convex groove 308, allowing the first connector 310 to rotate 360 ​​degrees, ensuring reliable connection of the air pipe at different installation angles and preventing airflow leakage.

[0055] Furthermore, by rotating the middle ring 305 so that the first convex rod 306 is inside the first convex groove 304, the middle ring 305, along with the upper ring 307 and the first connector 310, can be used to adjust the angle.

[0056] Each connector 301 has a connector 4 fixedly installed at its front end, and each connector 4 is connected to the front end of the tee pipe 302.

[0057] The left end of the connecting pipe 4 is uniformly provided with arc-shaped grooves 401 in a ring array, and the left end of the two front connecting pipes 4 is provided with annular grooves 402. The annular grooves 402 and the arc-shaped grooves 401 are in a through-flow state. Figure 8 As shown.

[0058] A first mounting ring 403 is provided at the right end of the left connecting pipe 4. A first annular groove 404 is formed inside the end of the left connecting pipe 4 adjacent to the first mounting ring 403. A first convex ring 405 is rotatably installed inside the first annular groove 404. The adjacent ends of the two first convex rings 405 are in a fixed connection state, and their outer circumferential surfaces are the same as those of the connecting pipe 4. A first adjusting tooth groove 406 is formed on the outer circumferential surface at the middle position. Furthermore, a first retaining ring 407 is fixedly installed inside the two first convex rings 405. The right end of the first retaining ring 407 extends to the outside of the first mounting ring 403. Figure 12 As shown, during use, the right end of the first retaining ring 407 can slide into the inside of the right connecting pipe 4 through the arc groove 401. Then, under the rotation of the first adjusting tooth groove 406, the first convex ring 405 can rotate, thereby causing the first retaining ring 407 to rotate synchronously. After the first retaining ring 407 rotates, the arc-shaped block protruding on the outer circumference can be inside the annular groove 402, thereby preventing the first retaining ring 407 from moving laterally, thus making the left and right connecting pipes 4 in a through state.

[0059] Then, a plug assembly 5 is provided on the left side of the left connecting pipe 4. The plug assembly 5 includes a plug 501. A second mounting ring 502 is provided at the right end of the plug 501. A second annular groove 503 is respectively opened from the adjacent end of the second mounting ring 502 and the plug 501 to the inside. A second convex ring 504 is rotatably installed inside the second annular groove 503. The middle part of the second convex ring 504 is in a fixed connection state, and the outer diameter of the second mounting ring 502 is the same on the outer circumference surface. Figure 10 As shown, a second adjusting groove 505 is provided. Then, a second retaining ring 506 is fixedly installed inside the two second convex rings 504 on the left and right sides. The second retaining ring 506 first slides through the arc groove 401 to the inside of the left connecting pipe 4, and then rotates inside the second adjusting groove 505. This allows the arc-shaped block protruding on the outer circumference of the right side of the second retaining ring 506 to rotate inside the annular groove 402, thereby preventing the plug 501 from moving laterally. It should be noted that the plug 501 and the first retaining ring 407 mentioned above can only be rotated manually. They will not rotate under other circumstances to ensure that the structure will not leak.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
