Description

Technical Field

[0001] This utility model belongs to the field of air nozzles, specifically relating to a novel anti-slip high-pressure air nozzle and an inflatable device based on this air nozzle. Background Technology

[0002] Existing inflatable devices such as inflatable mats, air mattresses, and inflatable boats often use filamentous materials as connectors to fix the internal structure and maintain overall regularity. While filamentous materials have many advantages, their light weight often leads to unstable internal distribution when not tensioned. This is especially problematic when using an air pump to deflate the device, where the filaments near the air nozzle are easily pulled out. This not only damages the air nozzle itself but also causes significant damage to the structure of the inflatable device. Therefore, it is necessary to design an air nozzle that avoids filament pulling to solve the problems existing in current technology. Summary of the Invention

[0003] To address the above issues, this application presents a novel anti-fragmentation high-pressure air nozzle and an inflatable material based on this nozzle, which solves the problem that existing high-pressure air nozzles are prone to fragmentation, resulting in damage to the fragmentation structure.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This application provides a novel anti-spinning high-pressure nozzle, comprising an inflation / extraction assembly and an anti-spinning assembly. The anti-spinning assembly is characterized in that it is installed at one end of the inflation / extraction assembly, which is located inside the inflation gas. The anti-spinning assembly includes a mesh cover, a welding body, and an adapter. The adapter is embedded in the middle of the welding body and connected to the inflation / extraction assembly. The welding body is connected to the mesh cover and has a matching locking structure. The mesh cover has a mesh panel.

[0006] Preferably, the outer circumference of the welding body is provided with a connecting edge, and the connecting edge is made of a high-frequency hot-pressable material.

[0007] Preferably, the connecting edge is made of TPU or PVC material.

[0008] Preferably, the inflation / deflation assembly includes an air stop component, a screwing body, a return spring, and an air stop screwing head. The screwing body has an opening that matches the air stop component. The air stop component has a connecting post in the middle. The connecting post passes through the screwing body and connects to the air stop screwing head. The screwing body has a spring base in the middle. The return spring is sleeved on the outer ring of the connecting post. One end of the return spring abuts against the spring base, and the other end abuts against the air stop screwing head.

[0009] Preferably, the spring base includes a cross frame and a base. The base is located in the middle of the cross frame and is composed of two semi-cylinders. One end of the base abuts against the restoring spring, and the other end extends in the opposite direction. The two semi-cylinders are respectively located on both sides of the cross frame, and a base groove is formed in the middle part. The end of the semi-cylinder away from the cross frame is also provided with an end groove.

[0010] The connecting column has a protruding shoulder. When the protruding shoulder is placed in the base slot, the air stop and the screwing body are in a closed state. When the protruding shoulder is placed in the end groove, the air stop and the screwing body are in an open state.

[0011] Preferably, the end of the semi-cylinder away from the crossbeam is provided with a guide angle.

[0012] Preferably, the inflation / deflation assembly further includes an outer cover, which includes an outer cover portion and a fixing post that are fixedly connected. The bottom of the fixing post is provided with an arc-shaped groove and a protrusion. The outer cover is detachably connected to the spring base of the screwing body through the fixing post.

[0013] Preferably, it also includes a first sealing ring, which is fixed at a first slot on the top of the fixed post, and the screwing body is provided with a first groove that matches the first sealing ring.

[0014] Preferably, it also includes a second sealing ring, which is fixed at the second slot of the screwing body.

[0015] Preferably, it also includes a third sealing ring, which is fixed at the third groove of the air-stopping member.

[0016] On the other hand, this utility model provides an inflatable material based on a novel anti-slip high-pressure air nozzle.

[0017] An inflatable material includes an inflatable layer, the inflatable layer using a novel anti-snagging high-pressure air nozzle as described in any of the above technical solutions.

[0018] The beneficial effects of this utility model are:

[0019] This application incorporates an anti-filament-pulling component before the inflation / deflation assembly. During deflation, the internal filament-pulling structure is blocked by a mesh when it approaches the nozzle, preventing filaments from being sucked into the nozzle and ensuring the integrity of the filament-pulling structure inside the inflatable material. Furthermore, this application features a connecting edge suitable for high-frequency welding. When the high-pressure nozzle is installed onto the inflatable material, high-frequency welding can replace the traditional screw-on fixing method, solving the problems of air leakage and loosening associated with screw-on fixing. Inflatable materials using this nozzle are less prone to filaments being sucked into the nozzle and are less likely to leak air or loosen. Attached Figure Description

[0043] Example 1

[0044] This application is attached. Figures 1-4 , Figure 11 A novel anti-spinning high-pressure air nozzle 100 is provided, including an air filling and pumping assembly 1 and an anti-spinning assembly 2. The anti-spinning assembly 2 is installed at one end of the air filling and pumping assembly 1 inside the air filling gas. The anti-spinning assembly 2 includes a mesh cover 21, a welding body 23 and an adapter 24. The adapter 24 is embedded in the middle of the welding body 23 and is connected to the air filling and pumping assembly 1. The welding body 23 is connected to the mesh cover 21 and is provided with a matching locking structure. The mesh cover 21 is provided with a mesh sheet 22.

[0045] The inflation / deflation assembly 1 can use other commercially available inflation / deflation structures, but the preferred method is the embodiment of the inflation / deflation assembly 1 described in this application. The adapter 24 can be fixedly embedded into the middle of the welding body 23 through injection molding to enhance connection stability. During assembly, the anti-snagging assembly 2 is preferably assembled with the mesh 22 pre-installed and fixed onto the mesh cover 21. The mesh 22 can be installed between the welding body 23 and the mesh cover 21, or on the outer surface of the mesh cover 21, or integrated with the mesh cover 21 itself (i.e., the mesh cover 21 and the mesh are integrally formed). The mesh cover 21 is then detachably connected to the welding body 23 via snap-fit ​​connections, threaded connections, etc. An adhesive, such as glue, can be injected between the mesh cover 21 and the welding body 23 to strengthen the connection. This combination speeds up assembly, and since the mesh cover 21 and the welding body 23 are detachable, replacement is simpler and more convenient later. Of course, in addition to the methods described above, each component can also be combined as a separate component. During installation, the components are assembled to form the anti-screw-pulling assembly 2. The separate components allow for individual replacement if a component is damaged, thereby reducing maintenance costs.

[0046] This application provides an anti-filament pulling structure composed of a welding body 23, a mesh 22, and a mesh cover 21 in front of the inflation / deflation assembly 1. When deflation occurs, the internal filament pulling structure is blocked by the mesh 22 when it approaches the air nozzle, thus preventing the filaments from being sucked into the air nozzle and ensuring the integrity of the filament pulling structure inside the inflatable material.

[0047] Example 2

[0048] In this embodiment, as Figures 2-4 As shown, the outer circumference of the welding body 23 is provided with a connecting edge 231, which is made of a high-frequency heat-pressable material. The main function of the connecting edge 231 is to connect with the inflatable material. The traditional connection method is to fix the air nozzle by setting clamps inside and outside the inflatable material. The common practice is to use threaded clamps. There is a threaded clamp A inside the inflatable material and a matching threaded clamp B on the outside of the inflatable material. The clamping action of clamp A and clamp B achieves sealing and relative fixation. However, this method is prone to problems such as air leakage and loosening. Now, by using a connecting edge 231 made of high-frequency heat-pressable material, the fabric of the inflatable material can be fixed to the air nozzle by high-frequency heat pressing. The high-frequency heat pressing method provides a firm connection and good sealing performance, which can effectively solve the problem of screw-type fixation.

[0049] The preferred method is to use TPU or PVC material for the high-frequency hot-pressable material of the connecting edge 231.

[0050] Example 3

[0051] In this embodiment, as Figure 1 , Figure 11 As shown, the inflation / deflation assembly 1 includes an air stopper 11, a screwing body 12, a return spring 13, and an air stop screwing head 14. The screwing body 12 has an opening that matches the air stopper 11. The air stopper 11 has a connecting post 111 in the middle. The connecting post 111 passes through the screwing body 12 and connects to the air stop screwing head 14. Figure 11 The two are fixedly connected by screws. The screwing body 12 has a spring base 121 in the middle. The restoring spring 13 is sleeved on the outer ring of the connecting post 111. One end of the restoring spring 13 abuts against the spring base 121, and the other end abuts against the air-stop screwing head 14.

[0052] The principle of this air-filling / air-evacuation assembly 1 is as follows: When a seal is required, the return spring 13 applies an upward force to the air-stopping screw head 14. Since the air-stopping screw head 14 is connected to the air-stopping element 11 via the connecting post 111, the air-stopping element 11 is also driven upward. The air-stopping element 11 can cover the matching openings on the screw-on body 12, thus achieving a seal. When an opening is required, a downward force can be applied to the air-stopping screw head 14. When the downward force is greater than the upward elastic force of the return spring 13, the air-stopping screw head 14 drives the air-stopping element 11 downward. At this time, the air-stopping element 11 will move away from the matching openings on the screw-on body 12, allowing gas to escape outward or flow inward.

[0053] Example 4

[0054] The difference between this embodiment and embodiment three is that when inflation or deflation is required, it is not necessary to continuously apply a downward force to the air stop screw head 14.

[0055] In this embodiment, as Figures 5-8 As shown, the spring base 121 includes a cross frame 122 and a base 123. The base 123 is located in the middle of the cross frame 122 and is composed of two semi-cylinders 124. One end of the base 123 abuts against the restoring spring 13, and the other end of the base 123 extends in the opposite direction. The two semi-cylinders 124 are respectively located on both sides of the cross frame 122, and the middle part forms a base groove 125. The end of the semi-cylinder 124 away from the cross frame 122 is also provided with an end groove 126.

[0056] The connecting column 111 is provided with a protruding shoulder 112. When the protruding shoulder 112 is placed in the base slot 125, the air stop 11 and the screwing body 12 are in a closed state. When the protruding shoulder 112 is placed in the end groove 126, the air stop 11 and the screwing body 12 are in an open state.

[0057] The method of use is as follows: In the closed state, the protruding shoulder 112 is placed in the base slot 125. Since there is no obstruction in the slot, the protruding shoulder 112 will move upward with the air stop 11 until the air stop 11 abuts against the matching opening on the screw body 12. At this time, the air stop 11 seals the opening of the screw body 12. When it is necessary to open, first apply a downward force to the air stop screw head 14, pushing it downward until the protruding shoulder 112 disengages from the base slot 125. Then, the air stop screw head 14 can be rotated. The air stop screw head 14 drives the air stop 11 to rotate, and the protruding shoulder 112 on the air stop 11 also rotates. When the protruding shoulder 112 is rotated into the end groove 126, the pressure applied to the air stop screw head 14 can be stopped. At this time, since the end groove 126 holds the protruding shoulder 112, the protruding shoulder 112 cannot slide into the base slot 125, and the gas can be discharged outward or rush inward. When you need to close it again, simply rotate the airlock screw head 14 until the protruding shoulder 112 slides back into the base slot 125.

[0058] Furthermore, the end of the semi-cylinder 124 away from the crossbar 122 is provided with a guide angle 127. The guide angle 127 is an inclined surface, which can be a rounded corner, a chamfer, or other curved angle. The purpose of the guide angle 127 is to facilitate rotation from a lower position, rotating the protruding shoulder 112 into the end groove 126.

[0059] Example 5

[0060] In this embodiment, as Figure 10As shown, the inflation / deflation assembly 1 also includes an outer cover 15. The outer cover 15 includes an outer cover portion 151 and a fixing post 152 that are fixedly connected. The bottom of the fixing post 152 is provided with an arc-shaped groove 153 and a protrusion 154. The outer cover 15 is detachably connected to the spring base 121 of the screwing body 12 through the fixing post 152.

[0061] Specifically, the bottom of the fixing post 152 is provided with an arc-shaped groove 153, and the screwing body 12 is provided with a spring base 121. The spring base 121 includes a crossbeam 122. When sealing and fixing are required, the bottom entrance of the arc-shaped groove 153 is aligned with the crossbeam 122, so that the crossbeam 122 can be placed at the bottom entrance of the arc-shaped groove 153. Then, the outer cover 15 is rotated. Due to the presence of the arc-shaped groove 153, during the rotation, the crossbeam 122 will be screwed into the interior of the arc-shaped groove 153 from the entrance of the arc-shaped groove 153. After being fully tightened, the outer cover 15 cannot be removed because the crossbeam 122 jams the protrusion 154, thus achieving further sealing.

[0062] A preferred embodiment further includes a first sealing ring 3, which is fixed to a first slot 31 at the top of the fixing post 152, and the screwing body 12 is provided with a first groove 32 that matches the first sealing ring 3. The first sealing ring 3 further improves the sealing performance.

[0063] Example 6

[0064] In this embodiment, as Figure 1 , Figure 7 As shown, the new type of anti-thread-pulling high-pressure air nozzle also includes a second sealing ring 4, which is fixed in the second slot 41 of the screw-on body 12. Figure 1 , Figure 9 , Figure 11 As shown, it also includes a third sealing ring 5, which is fixed in the third slot 51 of the air-stopping component 11. Figure 11 The diagram shows that the third slot 51 is formed by connecting the upper and lower parts of the air-stopping element 11 together with screws, thus fixing the third sealing ring 5. The second sealing ring 4 and the third sealing ring 5 serve to further improve the sealing performance.

[0065] Example 7

[0066] In this embodiment, an inflatable object 200 is provided, including an inflatable layer 210, which uses any of the novel anti-snagging high-pressure air nozzles 100 described in the foregoing embodiments.
