Description

Technical Field

[0001] This utility model relates to the field of inflatable toys, and in particular to an air inlet mechanism for inflatable toys with strong sealing performance. Background Technology

[0002] Inflatable toys are widely used in children's entertainment and outdoor leisure activities due to their lightweight, portability, and reusability. As the core component of inflatable toys, the performance of the air inlet directly affects the user experience.

[0003] Currently, most inflatable toys on the market use fixed-size rubber sealing rings to seal the air inlet. To ensure a good seal, the sealing ring must fit tightly against the inner wall of the air inlet tube. This results in relatively high resistance when inserting the air inlet tube, especially when children or the elderly operate it. Improper force often leads to misalignment or failure to insert the tube, causing inconvenience during inflation. Furthermore, even slight dimensional deviations in the air inlet tube or wear on the sealing ring surface due to frequent insertion and removal can easily cause seal failure, leading to gas leakage during inflation. This not only prolongs inflation time but also directly reduces the toy's lifespan.

[0004] To address the issues of traditional air inlets where "good sealing leads to difficulty in insertion and removal, while easy insertion and removal results in poor sealing," as well as the problem of poor compatibility with air injection pipes.

[0005] Therefore, it is necessary to provide a new air inlet mechanism with strong sealing for inflatable toys to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an air inlet mechanism with strong sealing performance for inflatable toys.

[0007] This utility model provides an air inlet mechanism for an inflatable toy with strong sealing performance, comprising: an air inlet seat, on which an air inlet pipe is fixedly connected, a limiting ring being provided on the outer wall of the air inlet pipe, and a one-way air valve being installed and connected in the air inlet pipe; and a high-efficiency sealing mechanism, comprising an embedded airbag ring, an embedded groove being provided on the outer wall of one end of the air inlet pipe, the embedded airbag ring being fixedly installed in the embedded groove, two connecting pipes being symmetrically provided on the limiting ring, two side short pipes being symmetrically fixedly connected on the outer wall of the air inlet pipe, a bent pipe being fixedly connected to one end of each of the two side short pipes, and a compression component being provided in each of the two side short pipes.

[0008] Preferably, two built-in air passages are symmetrically provided on the groove wall of the embedded groove. One end of each of the two built-in air passages is connected to the embedded airbag ring, and the other end of each of the two built-in air passages is connected to two connecting pipes respectively. The two bent pipes are fixedly connected to the two connecting pipes respectively.

[0009] Preferably, the extrusion assembly includes a piston disposed inside the side short tube, and a slide rod is slidably connected to one end of the side short tube wall, with one end of the slide rod being fixedly connected to the piston.

[0010] Preferably, a mating ring is fitted around the outside of the air intake pipe, and the lower ends of both slide rods are fixedly connected to the mating ring.

[0011] Preferably, a rotating ring is provided below the docking ring, the inner wall of the rotating ring is provided with an internal thread, the outer wall of the air intake pipe is provided with an external thread, and the rotating ring is threadedly connected to the pipe wall of the air intake pipe.

[0012] Preferably, the outer wall of the rotating ring is provided with an annular groove, and the lower end of the docking ring is provided with an internal retaining ring, which is engaged in the annular groove, and the docking ring is rotatably connected to the rotating ring.

[0013] Compared with related technologies, the air inlet mechanism for inflatable toys with strong sealing provided by this utility model has the following beneficial effects:

[0014] 1. This utility model provides an embedded groove on the wall of the air inlet pipe and fixes an embedded airbag ring in the groove. During the insertion of the air injection pipe, the embedded airbag ring is in a contracted state and will not obstruct the air injection pipe. This effectively solves the problem of difficult insertion caused by the matching of the specifications of traditional sealing rings with the inner wall of the pipe, making the insertion process easy and effortless. Moreover, the inflated embedded airbag ring is in surface contact with the inner wall of the air injection pipe. Compared with the line contact of traditional sealing rings, the sealing area is larger and the sealing effect is more stable and reliable. The elastic deformation of the airbag ring is used to achieve effective sealing, ensuring good sealing performance and avoiding air leakage during inflation.

[0015] 2. This utility model moves the rotating ring relative to the intake pipe by rotating it. Since the rotating ring is threaded to the outer wall of the intake pipe, it moves upward along the intake pipe axis. Because the internal retaining ring at the lower end of the mating ring is engaged in the annular groove of the rotating ring, the rotating ring drives the mating ring to slide upward synchronously. This causes the mating ring to push the two sliding rods to slide relative to the two side short pipes. The movement of the piston drives the stored air to be delivered to the embedded airbag ring, which effectively controls the expansion and contraction of the embedded airbag ring, allowing users to quickly control the sealing state.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 3 An air inlet mechanism for an inflatable toy with strong sealing includes: an air inlet seat 1, an air inlet pipe 2 fixedly connected to the air inlet seat 1, a limiting ring 21 on the outer wall of the air inlet pipe 2, and a one-way air valve 3 installed and connected in the air inlet pipe 2; and a high-efficiency sealing mechanism, including an embedded airbag ring 4, an embedded groove on the outer wall of one end of the air inlet pipe 2, the embedded airbag ring 4 fixedly installed in the embedded groove, two connecting pipes 41 symmetrically provided on the limiting ring 21, two side short pipes 42 symmetrically fixedly connected to the outer wall of the air inlet pipe 2, a bent pipe 43 fixedly connected to one end of each of the two side short pipes 42, and a compression component in each of the two side short pipes 42.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, two built-in air passages are symmetrically arranged on the groove wall of the embedded groove. One end of each of the two built-in air passages is connected to the embedded airbag ring 4, and the other end of each of the two built-in air passages is connected to two connecting pipes 41 respectively. Two bent pipes 43 are fixedly connected to the two connecting pipes 41 respectively.

[0023] It should be noted that the built-in air passage is a channel opened inside the wall of the air intake pipe 2, which connects the side short pipe 42 with the embedded airbag ring 4 to form a gas flow path. When the gas in the side short pipe 42 is squeezed, it can smoothly enter the embedded airbag ring 4 through the built-in air passage and the connecting pipe 41, providing a gas source for the expansion of the embedded airbag ring 4.

[0024] The compressed gas flows into the embedded airbag ring 4, causing the embedded airbag ring 4 to expand. The expanded embedded airbag ring 4 can tightly fit the inner wall of the air injection tube, forming an effective seal.

[0025] refer to Figure 2 and Figure 3 As shown, the extrusion assembly includes a piston 5, which is located inside the side short tube 42. A slide rod 51 is slidably connected to one end of the side short tube 42, and one end of the slide rod 51 is fixedly connected to the piston 5.

[0026] It should be noted that the piston 5 is tightly fitted to the inner wall of the side short tube 42, ensuring the airtightness of the gas inside the side short tube 42. When the slide rod 51 drives the piston 5 to move, it can effectively squeeze the gas inside the side short tube 42, causing the gas to flow in a directional direction to the embedded airbag ring 4.

[0027] refer to Figure 2 and Figure 3 As shown, a mating ring 6 is fitted around the outside of the air intake pipe 2, and the lower ends of the two slide rods 51 are fixedly connected to the mating ring 6.

[0028] It should be noted that the coupling ring 6 is linked to the two slide rods 51, so that the two slide rods 51 can move synchronously, thereby ensuring that the pistons 5 in the two side short tubes 42 simultaneously compress the gas.

[0029] refer to Figure 1 and Figure 2 As shown, a rotating ring 7 is provided below the docking ring 6. The inner wall of the rotating ring 7 is provided with an internal thread, and the outer wall of the air intake pipe 2 is provided with an external thread. The rotating ring 7 is threadedly connected to the pipe wall of the air intake pipe 2.

[0030] It should be noted that the threaded connection between the rotating ring 7 and the air intake pipe 2 has the characteristics of smooth transmission and good self-locking. It can precisely control the axial movement distance of the rotating ring 7 by rotating it, and can keep the rotating ring 7 stably in the current position when it stops rotating, so as to prevent affecting the sealing state of the embedded airbag ring 4.

[0031] refer to Figure 1 and Figure 2 As shown, the outer wall of the rotating ring 7 is provided with an annular groove, and the lower end of the mating ring 6 is provided with an internal retaining ring 71. The internal retaining ring 71 is engaged in the annular groove, and the mating ring 6 is rotatably connected to the rotating ring 7.

[0032] It should be noted that the internal retaining ring 71 and the annular groove are fitted with a clearance fit, so that the mating ring 6 can move synchronously along the axial direction with the rotating ring 7, thereby further driving the slide rod 51 to move axially.

[0033] The working principle of the air inlet mechanism for inflatable toys with strong sealing provided by this utility model is as follows: When it is necessary to inflate the inflatable toy, insert the air injection tube into the air inlet tube 2 until the end of the air injection tube abuts against the limiting ring 21. At this time, rotate the rotating ring 7. Since the rotating ring 7 is threadedly connected to the outer wall of the air inlet tube 2, the rotating ring 7 will move upward along the axis of the air inlet tube 2. And because the internal retaining ring 71 at the lower end of the docking ring 6 is engaged in the annular groove of the rotating ring 7, the rotating ring 7 will drive the docking ring 6 to slide upward synchronously.

[0034] When the docking ring 6 slides upward, it pulls the two sliding rods 51 to move upward along the side short tube 42. The sliding rods 51 then push the piston 5 to slide upward in the side short tube 42, compressing the gas in the side short tube 42. The compressed gas enters the built-in air passage through the side short tube 42, and then flows into the embedded airbag ring 4 through the docking tube 41, causing the embedded airbag ring 4 to expand. The expanded embedded airbag ring 4 can tightly fit the inner wall of the air injection tube, forming an effective seal.

[0035] After inflation, rotate the rotating ring 7 in the opposite direction. The rotating ring 7 moves downward along the air inlet pipe 2, driving the docking ring 6 and the slide rod 51 to reset. The piston 5 slides downward in the side short pipe 42, and the gas in the embedded airbag ring 4 flows back to the side short pipe 42. The embedded airbag ring 4 contracts, and the inflation tube can be easily pulled out at this time. The one-way air valve 3 can effectively prevent gas leakage in the inflatable toy.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
