Description
Technical Field
[0001] This utility model relates to the field of inflation equipment technology, specifically to a quick connection structure for an inflation head. Background Technology
[0002] The inflation head is a key component in inflation equipment, used to transfer gas between the air source and the object to be inflated, acting as a "bridge" connecting the two. One end connects to the air source device, such as an air pump or air tank, to receive compressed gas, while the other end adapts to various interfaces on the object to be inflated, such as tire valves, ball valves, and inflatable tent valves. Through its internal gas channel design, combined with seals, valves, and other components, the inflation head can effectively control the direction and flow of gas, ensuring airtightness while achieving safe and efficient inflation.
[0003] In existing technologies, in many scenarios that require inflation, such as inflating car tires, inflating balls, and setting up inflatable tents, the connection between the inflation head and the object being inflated is crucial. The inflation device applies gas pressure, causing the object to expand rapidly.
[0004] However, when connecting the inflation head to the connector on the inflation device, such as with a threaded connection, it takes a lot of time to tighten, resulting in slow connection speed and low efficiency. After long-term use, the threaded interface is prone to wear, corrosion, or contamination with dirt and sand, which makes the tightening process more difficult. It not only consumes more physical strength, but may also cause the threads to strip due to excessive force, resulting in damage to the inflation head or connector. To address this, we propose a quick connection structure for the inflation head. Utility Model Content
[0005] One of the technical problems this application aims to solve is to effectively improve the efficiency of inflation by enabling quick connection between the inflation head and the connector on the inflation device.
[0006] To address the aforementioned technical problems, this application provides a quick-connect structure for an inflatable head, comprising a connecting mechanism. A handheld mechanism is provided on one side of the connecting mechanism. The connecting mechanism includes an inflatable head body, a locking plate on one side of the inflatable head body, and a fixed connection between one side of the inflatable head body and the bottom end of the locking plate. A fixing rod is provided on the inner wall of the top of the locking plate, and the inner wall of the top of the locking plate is rotatably engaged with the outer side of one end of the fixing rod. An outer ring is provided at the top of the fixing rod, and the top of the fixing rod is slidably connected perpendicularly to the inner wall of the outer ring. A connecting seat is provided on the inner side of the outer ring, and the inner side of the outer ring is rotatably connected to the outer side of the connecting seat.
[0007] In some embodiments, the handheld mechanism includes a hand frame, one side of which is provided with an anti-slip pad, one side of which is fixedly connected to one side of the anti-slip pad, and one end of which is fixedly connected to one side of the connecting seat.
[0008] In some embodiments, a protrusion is provided on the top side of the outer ring, the top side of the outer ring is fixedly connected to the bottom end of the protrusion, and the outer side of the protrusion is vertically slidably engaged with the inner wall of the connecting seat.
[0009] In some embodiments, a mother rod is provided inside the outer ring, the inside of the outer ring is rotatably in contact with the top end of the mother rod, and a spring is provided at the bottom end of the mother rod, the bottom end of the mother rod being fixedly connected to the top end of the spring.
[0010] In some embodiments, the bottom end of the spring is provided with a sub-rod, the bottom end of the spring is fixedly connected to the top end of the sub-rod, the interior of the sub-rod is slidably connected to the exterior of the mother rod, and the bottom end of the sub-rod is fixedly connected to the inner top end of the connecting seat.
[0011] In some embodiments, an annular groove is provided on the outer side of the connecting seat, and a side plate is provided on the inner surface of the annular groove. The inner surface of the annular groove is rotatably in contact with one end of the side plate, and the other end of the side plate is fixedly connected to one side of the fixing rod.
[0012] In some embodiments, a limiting groove is formed in the inner wall of the connecting seat, and a guide rod is provided on the inner surface of the limiting groove. The inner surface of the limiting groove is rotatably in contact with the outer side of the bottom end of the guide rod.
[0013] In some embodiments, the top end of the guide rod is fixedly connected to the bottom end of the fixing rod.
[0014] This utility model has at least the following beneficial effects:
[0015] 1. Connect the inflator head body to the connecting seat by slightly pressing the outer ring and then rotating it from 0 to 30 degrees. This will cause the fixing rod to rotate along the same path. When it is rotated to 30 degrees, the fixing rod will pass through the top inner wall of the locking plate, thus limiting the position of the locking plate and keeping the inflator head body and the connecting seat stable during the connection process. This method eliminates the need for tedious multi-turn screwing. The operator only needs to align the inflator head body and the connecting seat, press and rotate the outer ring to complete the connection.
[0016] 2. When the outer ring is pressed slightly, the female rod will move down while the male rod contracts. Then, after the locking plate and the fixing rod are connected, the pressure on the outer ring is released, and the spring will release energy to lift the outer ring. When the outer ring is lifted, it will slide on the fixing rod. At the same time, the protrusion enters the connecting seat to fix the position of the outer ring after rotation, effectively preventing the fixing rod from accidentally disengaging from the locking plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: Please refer to Figures 1-7This utility model provides a technical solution: a quick connection structure for an inflatable head, including a connecting mechanism 1, a handheld mechanism 2 on one side of the connecting mechanism 1, the connecting mechanism 1 including an inflatable head body 11, a locking plate 12 on one side of the inflatable head body 11, one side of the inflatable head body 11 being fixedly connected to the bottom end of the locking plate 12, a fixing rod 16 on the inner wall of the top of the locking plate 12, the inner wall of the top of the locking plate 12 being rotatably engaged with the outer side of one end of the fixing rod 16, an outer ring 14 on the top of the fixing rod 16, the top of the fixing rod 16 being vertically slidably connected to the inner wall of the outer ring 14, a connecting seat 13 on the inner side of the outer ring 14, the inner side of the outer ring 14 being rotatably connected to the outer side of the connecting seat 13, a protrusion 17 on the top side of the outer ring 14, the top side of the outer ring 14 being fixedly connected to the bottom end of the protrusion 17, the outer side of the protrusion 17 being vertically slidably engaged with the inner wall of the connecting seat 13, a female rod 110 on the inside of the outer ring 14, and an outer... The inner part of ring 14 is rotatably in contact with the top end of the mother rod 110. A spring 111 is provided at the bottom end of the mother rod 110, and the bottom end of the mother rod 110 is fixedly connected to the top end of the spring 111. A daughter rod 19 is provided at the bottom end of the spring 111, and the bottom end of the spring 111 is fixedly connected to the inner end of the top end of the daughter rod 19. The inner part of the daughter rod 19 is slidably connected to the outer side of the mother rod 110. The bottom end of the daughter rod 19 is fixedly connected to the inner top end of the connecting seat 13. The outer side of the connecting seat 13 is open. An annular groove 15 is provided, and a side plate 18 is provided on the inner surface of the annular groove 15. The inner surface of the annular groove 15 is rotatably in contact with one end of the side plate 18, and the other end of the side plate 18 is fixedly connected to one side of the fixing rod 16. A limiting groove 113 is provided on the inner wall of the connecting seat 13, and a guide rod 112 is provided on the inner surface of the limiting groove 113. The inner surface of the limiting groove 113 is rotatably in contact with the outer side of the bottom end of the guide rod 112, and the top end of the guide rod 112 is fixedly connected to the bottom end of the fixing rod 16.
[0028] In traditional use, this type of quick-connect structure for the inflation head connects to the connecting seat 13 of the inflation device by screwing. However, because a locking plate 12 is designed on one side of the inflation head body 11, the inflation head body 11 and the connecting seat 13 are connected by fitting them together. The connecting seat 13 has a groove, and the locking plate 12 needs to be aligned with the groove before connecting the inflation head body 11 and the connecting seat 13. Furthermore, to ensure a tight connection between the inflation head body 11 and the connecting seat 13 after connection, an annular groove 15 is provided on the outer side of the connecting seat 13, and a side plate 18 is designed on the inner surface of the annular groove 15. A fixing rod is fixedly connected to the other end of the side plate 18. 16. The outer ring 14 is vertically slidably connected to the outer side of the top of the fixing rod 16. Then, by slightly pressing the outer ring 14 and rotating it from 0 to 30 degrees, the fixing rod 16 rotates along the same rotation path. When it is rotated to 30 degrees, the fixing rod 16 will pass through the inner wall of the top of the locking plate 12, thereby limiting the position of the locking plate 12 and keeping the inflation head body 11 and the connecting seat 13 stable during the connection process. In this way, there is no need for tedious multi-turn screwing. The operator only needs to align the inflation head body 11 and the connecting seat 13, press and rotate the outer ring 14 to complete the connection. The whole process can be completed in a few seconds.
[0029] A protrusion 17 is provided on the top side of the outer ring 14. Therefore, when the fixing rod 16 passes through the locking plate 12, since a female rod 110 is provided inside the outer ring 14 and a male rod 19 is designed on the outside of the female rod 110, and a spring 111 is designed between the female rod 110 and the male rod 19, when the outer ring 14 is pressed slightly, the female rod 110 will move down on the male rod 19 and the spring 111 will contract. Then, when the locking plate 12 and the fixing rod 16 are connected, the pressure on the outer ring 14 is released, and the spring 111 will release energy to lift the outer ring 14. When the outer ring 14 is lifted, it will slide on the fixing rod 16. At the same time, the protrusion 17 enters the connecting seat 13 and fixes the position of the outer ring 14 after rotation, effectively preventing the fixing rod 16 from accidentally disengaging from the locking plate 12. This provides a long-term and stable connection guarantee for the inflation system, and effectively prevents accidental rotation and unlocking caused by accidental contact or external force, ensuring that the connection is always stable and reliable in harsh environments.
[0030] In order to ensure that the protrusion 17 can accurately enter the connector 13, a limiting groove 113 is provided on the connector 13. The limiting groove 113 has a range of 0 to 30 degrees. Thus, the setting of the limiting groove 113 provides a precise rotation track for the protrusion 17. When the operator rotates the outer ring 14, the protrusion 17 will slide smoothly along the limited range of 0 to 30 degrees. When it slides to 30 degrees, the protrusion 17 will correspond to the groove on the connector 13, so that the operator can intuitively perceive the connection completion status.
[0031] Example 2: Please refer to Figure 1 The handheld mechanism 2 includes a hand frame 21, with an anti-slip pad 22 on one side of the hand frame 21. One side of the hand frame 21 is fixedly connected to one side of the anti-slip pad 22, and one end of the hand frame 21 is fixedly connected to one side of the connecting seat 13.
[0032] Since multiple components are installed on the connector 13 and the components occupy part of the space of the connector 13, a hand rest 21 is additionally designed on one side of the connector 13. The hand rest 21 provides the operator with an independent grip support. With the hand rest 21, even in a small and complex equipment layout, it is easy to apply force to rotate the outer ring 14 and insert or remove the inflation head, avoiding operation jamming or errors due to insufficient space. At the same time, an anti-slip pad 22 is designed on one side of the hand rest 21. The rubber material on the surface of the anti-slip pad 22 can effectively increase friction and avoid operation errors caused by slipping hands.
[0033] Please see Figures 1-7 The inflation head body 11 is fitted and connected to the connecting seat 13. Then, by slightly pressing the outer ring 14 and rotating the outer ring 14 from 0 to 30 degrees, the fixing rod 16 rotates along the same rotation path. When it rotates to 30 degrees, the fixing rod 16 will pass through the top inner wall of the locking plate 12, thereby limiting the position of the locking plate 12 and ensuring that the inflation head body 11 and the connecting seat 13 remain stable during the connection process. A protrusion 17 is provided on the top side of the outer ring 14. Therefore, when the fixing rod 16 passes through the locking plate 12, since a female rod 110 is provided inside the outer ring 14 and a female rod 19 is designed on the outside of the female rod 110, and a spring 111 is designed between the female rod 110 and the female rod 19, when the outer ring 14 is slightly pressed, the female rod 110 will be able to rotate through the locking plate 12. As the sub-rod 19 moves downward, the spring 111 contracts. Then, after the locking plate 12 and the fixing rod 16 are connected, the pressure on the outer ring 14 is released, and the spring 111 releases energy to lift the outer ring 14. When the outer ring 14 is lifted, it slides on the fixing rod 16. At the same time, the protrusion 17 enters the connecting seat 13 to fix the position of the outer ring 14 after rotation. Finally, a limiting groove 113 is opened on the connecting seat 13. The range of the limiting groove 113 is from zero to thirty degrees. Thus, the setting of the limiting groove 113 provides a precise rotation track for the protrusion 17. When the operator rotates the outer ring 14, the protrusion 17 will slide smoothly along the limited range of zero to thirty degrees. When it slides to thirty degrees, the protrusion 17 will correspond to the groove on the connecting seat 13.
[0034] An additional hand rest 21 is designed on one side of the connecting seat 13. The hand rest 21 provides the operator with an independent gripping fulcrum. With the hand rest 21, even in a small and complex equipment layout, it is easy to apply force to rotate the outer ring 14 and insert or remove the inflation head, avoiding operation jamming or errors due to insufficient space. At the same time, an anti-slip pad 22 is designed on one side of the hand rest 21. The rubber material on the surface of the anti-slip pad 22 can effectively increase the friction.
