Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of inflatable toys, specifically to a highly sealed air inlet for inflatable toys. Background Technology
[0002] Inflatable toys are toys that utilize the tension of a thin film material and the pressure difference between the inside and outside of the film to form a shape. They are small in volume after deflation, making them easy to carry and store. Inflatable toys can be categorized by material, including PE film inflatable toys, PVC film inflatable toys, TPU and EVA environmentally friendly inflatable products, mesh fabric and Oxford cloth inflatable toys, rubber-plastic inflatable products, and vinyl inflatable animals, among others. However, existing inflatable toys often have poor sealing performance at the air inlet. When using inflatable toys, we frequently find that they easily "collapse." Furthermore, even when the air inlet is removed, it remains open, leading to partial gas leakage and affecting usability. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a highly airtight air inlet for inflatable toys.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model relates to a high-sealing air inlet for an inflatable toy, comprising an air inlet body, an outer patch for adhering to the inflatable toy, the patch being fixed to the upper surface of the inflatable toy by a fixing adhesive layer, a sealing plate at the bottom of the air inlet body, an air inlet hole on the sealing plate, and a connecting pipe for connecting the air inlet hole on the sealing plate, and a vertically upward sliding rod mounted on the inner end of the air inlet body via a fixing frame, the top of the sliding rod having a closing block for closing the air inlet hole, the outer side of the closing block having a first rubber sealing layer, and a compression spring between the closing block and the sliding rod;
[0006] The bottom of the closure block is provided with an insertion tube that extends into the connecting tube. The middle part of the insertion tube is provided with a cavity for inserting an air nozzle, and the lower end of the insertion tube is provided with an air inlet that communicates with the cavity.
[0007] As a preferred embodiment of this utility model, the cavity is provided with a second rubber sealing layer.
[0008] As a preferred embodiment of this utility model, the upper part of the insertion cavity is provided with a guide cavity with a diameter larger than that of the insertion cavity.
[0009] As a preferred embodiment of this utility model, the lower end of the insertion cavity of the insertion tube is provided with a limiting ring block for limiting the inflation nozzle, and the upper end of the insertion tube is provided with multiple sealing rings for sealing the connection between the connecting tube and the insertion tube.
[0010] As a preferred embodiment of this utility model, the top of the insertion tube is at a higher level than the top of the connecting tube, but lower than the outer end of the air nozzle body.
[0011] As a preferred embodiment of this utility model, the air nozzle body is connected to a cap for sealing the air nozzle body via a flexible connecting piece.
[0012] As a preferred embodiment of this utility model, the bottom of the closing block is provided with a screw hole, and the top of the slide rod is provided with a threaded section that is screwed into the screw hole.
[0013] The beneficial effects of this utility model are:
[0014] This inflatable toy features a highly sealed air inlet nozzle. An insertion tube extends into the connecting tube at the bottom of the closing block. The insertion tube has a cavity in the middle for inserting the air inlet nozzle, and its lower end has an air inlet communicating with the cavity. When the air inlet nozzle is inserted into the cavity, it moves the insertion tube downwards, connecting the air inlet to the interior of the nozzle body for inflation. When the air inlet nozzle is removed, the closing block moves upwards under the reset action of the compression spring, blocking the air inlet. Simultaneously, the upward movement of the closing block moves the insertion tube upwards, sending the air inlet into the connecting tube to close it. This prevents gas leakage if the seal is not closed promptly when the nozzle is removed. Therefore, the air inlet nozzle has a high sealing effect, preventing gas leakage during daily use and during insertion and removal. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the high-sealing air inlet of the inflatable toy of this utility model includes an air inlet body 1. The air inlet body 1 has a patch 2 on its outside that fits into the inflatable toy. The patch 2 is fixed to the upper surface of the inflatable toy by a fixing adhesive layer. The bottom of the air inlet body 1 is provided with a sealing plate 3. The sealing plate 3 has an air inlet 4 and a connecting pipe 5 connected to the air inlet 4. The inner end of the air inlet body 1 is mounted with a vertically upward sliding rod 7 via a fixing frame 6. The top of the sliding rod 7 is provided with a closing block 8 for closing the air inlet 4. The outside of the closing block 8 is provided with a first rubber sealing layer 9. A compression spring 10 is provided between the closing block and the sliding rod.
[0023] The bottom of the closing block 8 is provided with an insertion tube 11 that extends into the connecting tube 5. The middle of the insertion tube 11 has a cavity 12 for inserting an inflation nozzle, and the lower end of the insertion tube 11 has an air inlet 13 communicating with the cavity 12. By providing an insertion tube 11 at the bottom of the closing block 8 that extends into the connecting tube 5, a cavity 12 for inserting an inflation nozzle in the middle of the insertion tube 11, and an air inlet 13 communicating with the cavity 12 at the lower end of the insertion tube 11, the inflation nozzle, after being inserted into the cavity 12, moves the insertion tube 11 downwards, thus connecting the air inlet 13 with the interior of the nozzle body 1 for inflation. During the removal of the inflation nozzle, as the nozzle is pulled out, the compression spring... Under the reset action of 10, the closing block 8 moves upward to block the air inlet 4. At the same time, the upward-moving closing block 8 drives the insertion tube 11 to move upward, sending the air inlet 13 into the connecting tube 5 to close the air inlet 13. This avoids partial gas leakage when the air nozzle is pulled out if the cap 21 is not closed in time. In summary, the air inlet has a high sealing effect, preventing gas leakage in daily life and also preventing gas leakage when the air nozzle is inserted or removed.
[0024] The cavity 12 is provided with a second rubber sealing layer 15, which ensures a good seal between the inflation nozzle and the cavity 12.
[0025] The upper part of the insertion cavity 12 is provided with a guide cavity 16 with a diameter larger than that of the insertion cavity 12, which facilitates the insertion of the inflation nozzle.
[0026] The lower end of the insertion cavity 12 of the insertion tube 11 is provided with a limiting ring block 13 to limit the inflation nozzle, so as not to block the inflation part of the inflation nozzle. The upper end of the insertion tube 11 is provided with multiple sealing rings 14 for sealing the connection between the connecting tube 5 and the insertion tube 11, thus ensuring that the connection between the connecting tube 5 and the insertion tube 11 has a high degree of sealing.
[0027] The top of the insertion tube 11 is at a higher horizontal height than the top of the connecting tube 5, but lower than the outer end of the air nozzle body 1. This avoids air leakage caused by accidental triggering of the insertion tube. When air leakage is needed, the insertion tube can be pressed down to connect with the inner cavity of the air nozzle body through the air inlet.
[0028] The nozzle body 1 is connected to a cover 16 via a flexible connecting piece 15 for sealing the nozzle body 1. This closes the outer end of the nozzle body when not in use, thus preventing foreign objects from entering the nozzle body and blocking it.
[0029] The bottom of the closing block 8 is provided with a screw hole 17, and the top of the slide rod 7 is provided with a threaded section 18 that is screwed into the screw hole 17, which facilitates the assembly of the slide rod and the closing block.
[0030] Working principle: An insertion tube 11 extending into the connecting tube 5 is provided at the bottom of the closing block 8. The middle of the insertion tube 11 has a cavity 12 for inserting an inflation nozzle, and the lower end of the insertion tube 11 has an air inlet 13 communicating with the cavity 12. When the inflation nozzle is inserted into the cavity 12, the inflation nozzle moves the insertion tube 11 downwards, thus connecting the air inlet 13 with the interior of the nozzle body 1, thereby inflating. During the removal of the inflation nozzle, as the nozzle is pulled out, pressure... Under the reset action of the spring 10, the closing block 8 moves upward to block the air inlet 4. At the same time, the upward-moving closing block 8 drives the insertion tube 11 to move upward, sending the air inlet 13 into the connecting tube 5 to close the air inlet 13. This avoids partial gas leakage when the air nozzle is pulled out if the cap 21 is not closed in time. In summary, the air inlet has a high sealing effect, preventing gas leakage in daily life and also preventing gas leakage when the air nozzle is inserted or removed.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
