[0003] In existing air springs, the position of the air nozzle is relatively fixed during use, and it cannot be extended or retracted. As a result, after the air spring is inflated, the air nozzle is easily affected by external forces, which can damage the air nozzle and affect the service life of the air spring. Utility Model Content

[0004] The purpose of this invention is to solve the problems raised in the background art by proposing an air spring with a recessed air nozzle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design an air spring with a recessed air nozzle, including an air spring, a connecting seat, an air nozzle, and a telescopic structure. The connecting seat is fixedly provided on the upper outer wall of the air spring, the air nozzle is provided in the middle of the upper end of the air spring, and the telescopic structure is provided in the middle of the connecting seat. The telescopic structure includes a first gear, a sleeve, a guide seat, a slide rod, a second gear, and a compression spring. One side of the outer wall of the first gear is rotatably connected to the connecting seat, the middle part of the first gear is in contact with the sleeve, the inner wall of the sleeve is fixedly connected to the air nozzle, one side of the outer wall of the sleeve is fixedly connected to the guide seat, the two sides of the guide seat are slidably connected to the slide rod, the middle part of the outer wall of the first gear meshes with the first gear, the upper end of the second gear is fixedly connected to one end of the compression spring, and the other end of the compression spring is fixedly connected to the connecting seat.

[0006] Preferably, guide blocks are provided on both sides of the inner ring surface of the first gear, and two sets of spiral grooves are provided on the outer ring surface of the sleeve, with the spiral grooves on both sides being distributed in an equiangular ring, and the outer wall of the guide block can match the spiral grooves.

[0007] Preferably, the upper end of the inner wall of the connecting seat is provided with a plurality of limiting blocks, and the plurality of limiting blocks are distributed in a ring at an equal angle to the axis of the second gear. The plurality of limiting blocks can mesh with the teeth of the second gear, and when the second gear is separated from the plurality of limiting blocks, it still meshes with the first gear.

[0008] Preferably, the two ends of the slide rod are fixedly connected to the connecting seat and the air spring, respectively.

[0009] Preferably, one side of the outer wall of the second gear is in contact with the connecting seat.

[0010] Preferably, the side of the air nozzle adjacent to the air spring is a bellows, which is more conducive to the extension and retraction of the air nozzle.

[0011] The present invention discloses an air spring with a recessed nozzle, the advantages of which are as follows: by pressing down on the second gear, the second gear is separated from the limiting block, and then the second gear is rotated, which drives the first gear to rotate. The first gear drives the nozzle to rise through the sleeve for inflation. After inflation is completed, pressing down on the second gear reverses the rotation of the second gear, causing the nozzle to retract. Then, releasing the second gear, the second gear is affected by the spring force and matches the limiting block, thereby restricting the second gear and realizing the extension and retraction of the nozzle, thus protecting the nozzle from damage caused by collisions with external objects.

[0014] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-7An air spring with a recessed air nozzle 3 includes an air spring 1, a connecting seat 2, an air nozzle 3, and a telescopic structure 4. The connecting seat 2 is fixedly installed on the upper outer wall of the air spring 1, the air nozzle 3 is installed in the middle of the upper end of the air spring 1, and the telescopic structure 4 is installed in the middle of the connecting seat 2. The telescopic structure 4 includes a first gear 401, a sleeve 402, a guide seat 403, a slide rod 404, a second gear 405, and a compression spring 406. One side of the outer wall of the first gear 401 is rotatably connected to the connecting seat 2. The middle part of the first gear 401 is in contact with the sleeve 402. The inner wall of the sleeve 402 is fixedly connected to the air nozzle 3. One side of the outer wall of the sleeve 402 is fixedly connected to the guide seat 403. The two sides of the guide seat 403 are slidably connected to the slide rod 404 respectively. The middle part of the outer wall of the first gear 401 meshes with the first gear 401. The upper end of the second gear 405 is fixedly connected to one end of the compression spring 406. The other end of the compression spring 406 is fixedly connected to the connecting seat 2. A hexagonal groove is provided at the middle of the top of the second gear 405. By moving the second gear 405 through the corresponding hexagonal wrench, the second gear 405 can drive the first gear 401 to rotate. The guide blocks 4011 on both sides of the first gear 401 can slide along the spiral groove and drive the sleeve 402 to move. The sleeve 402 drives the guide seat 403 to move along the guide rod 404. The sleeve 402 drives the air nozzle 3 to rise.

[0015] Guide blocks 4011 are respectively provided on both sides of the inner ring surface of the first gear 401, and two sets of spiral grooves 4021 are provided on the outer ring surface of the sleeve 402. The spiral grooves 4021 on both sides are distributed in an equiangular ring. The outer wall of the guide block 4011 can match the spiral groove 4021. By pressing down the second gear 405 to separate it from the limiting block 201, the rotation of the second gear 405 is realized. By releasing the second gear 405, the elastic force of the spring 406 drives the second gear 405 to engage with the limiting block 201, thereby restricting the rotation of the second gear 405.

[0016] Multiple limiting blocks 201 are provided on the upper end of the inner wall of the connecting seat 2, and the multiple limiting blocks 201 are distributed in a ring at the same angle around the axis of the second gear 405. The multiple limiting blocks 201 can mesh with the teeth of the second gear 405. When the second gear 405 is separated from the multiple limiting blocks 201, it still meshes with the first gear 401.

[0017] The two ends of the slide rod 404 are fixedly connected to the connecting seat 2 and the air spring 1 respectively. One side of the outer wall of the second gear 405 is in contact with the connecting seat 2. The side of the air nozzle 3 adjacent to the air spring 1 is a bellows, which can realize the extension and retraction of the air nozzle 3.

[0018] Specifically, when inflating the air spring 1, the second gear 405 is pressed down to separate it from the limiting block 201. Then, the second gear 405 is rotated, causing the first gear 401 to rotate. The first gear 401, through the sleeve 402, causes the air nozzle 3 to rise and inflate. After inflation, the second gear 405 is pressed down and rotated in the opposite direction to retract the air nozzle 3. Then, the second gear 405 is released. The second gear 405 is then matched with the limiting block 201 by the elastic force of the spring 406, thereby restricting the extension and retraction of the air nozzle 3 and protecting it from damage caused by collisions with external objects.

[0019] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
