Description

Technical Field

[0001] The utility model belongs to the technical field of roof tents, and in particular relates to an air guide device for connecting two inflatable products. Background Art

[0002] Most of the existing roof tents on the market are made of metal bottom plates, hydraulic rods, metal shafts and aluminum alloy shells, which are heavy and difficult to install and support. The heavy weight of the roof tent not only increases the fuel consumption of the car, but also makes it inconvenient to disassemble and repair it.

[0003] In the utility model patent with announcement number CN218563228U, an inflatable roof tent support structure is disclosed. In this support structure, the entire base and support frame use inflatable airbags as supports, which are about half the weight of traditional metal tents, light in weight, and very convenient to carry outdoors. The base is made of brushed material, and the support is made of ordinary TPU (thermoplastic polyurethane elastomer rubber) / PVC (polyvinyl chloride) material. After use, just let out the air in the brushed airbag, fold it according to the size of the storage bag, and put it into the storage bag. When used outdoors, it can be placed in the trunk of the car for transportation, or in a locker for collection. When in use, you only need to connect the electric air pump to the power supply, connect the inflation port to the inflation and exhaust valves on the tent, and the tent can be quickly erected. In this way, the problem of heavy weight of metal roof tents is solved.

[0004] However, the patent only discloses the technical feature of connecting the support frame with a hose, but does not disclose how the hose is connected to the valve, nor how the connecting pipe and the air cushion are connected. Therefore, there is no convenient connection structure that can be quickly and effectively applied to different inflatable products, so a more reasonable solution is needed to solve the current technical problems. Utility Model Content

[0005] The utility model aims to provide an air guide device for connecting two inflatable products, so as to solve the problem that there is no convenient connection structure in the prior art that can be quickly and effectively applied to different inflatable products.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an air guide device for connecting two inflatable products, each inflatable product is provided with an air valve and an air valve cover for closing the air valve;

[0007] The air guide device comprises a control valve, a hose and a conversion joint, wherein the control valve is provided with at least two flow channels, and each flow channel is provided with a clamping spring; the hose and the conversion joint are both provided with a number corresponding to the flow channels, wherein one end of the hose is clamped in the clamping spring, and the other end is connected to the conversion joint;

[0008] Wherein, an elastic pressing structure is provided in the middle of the air valve core of the air valve, and the elastic pressing structure is connected to the air valve to close and open the air valve;

[0009] The air valve is also provided with a guide column, which protrudes toward the axis of the air valve core; one end of the conversion joint is provided with a sleeve for being inserted into the air valve, and the sleeve is provided with a vertical groove extending along the axial direction of the sleeve and a horizontal groove extending along the circumferential direction of the sleeve; the horizontal groove is connected to the vertical groove;

[0010] When the conversion joint is inserted along the axial direction of the air valve, the guide column is embedded in the vertical groove, and the conversion joint moves toward the air valve core and presses against the elastic pressing structure to open the air valve core; when the conversion joint is rotated along the circumferential direction of the air valve, the guide column is located in the horizontal groove.

[0011] In a possible design, a connecting column is provided at one end of the hose, a stud is provided on the conversion joint, and the connecting column is threadedly connected to the stud.

[0012] In a possible design, the air valve is provided with an engraving corresponding to the guide column.

[0013] In a possible design, the conversion joint is provided with a plurality of ridges, and the ridges are evenly spaced along the circumferential direction of the conversion joint.

[0014] In a possible design, the outer surface of the convex ridge is formed as a curved surface.

[0015] Through the above technical solution, based on the matching structure of the guide column and the sleeve, the conversion joint and the air valve can be locked. That is, when inflation is required, the sleeve is firmly inserted into the air valve; and after the inflation is completed, the conversion joint can be removed from the air valve by reverse operation. Through the matching structure of the sleeve and the air valve, the air guide device can be firmly connected to the inflatable product during inflation, and the reliability is good. Specifically, when applied, the conversion joint at the end of the hose can be connected to different inflatable products respectively, and then the control valve is opened, so that the air guide device is formed into a gas flow channel, which can allow the gas in different inflatable products to flow. For example, during the use of the inflatable roof tent, the user finds that the air column in the roof tent is not supportive enough and the hardness is insufficient. The air guide device can be used to connect the wire drawing pad to replenish the air in the air column. Specifically, the wire drawing pad is inflated with an air pump. When the wire drawing pad is full, the air pump is turned off, and the control valve on the air guide device is opened. The gas in the wire drawing pad will flow to the air column through the air guide device to achieve air column inflation. After the air column is fully inflated, close the control valve, remove the air guide device, and close the air valve. In this way, the air column can be inflated using an air pump on the vehicle without getting off the vehicle, which improves the convenience of inflation for users. In addition, the structure is simple, and users can quickly install and disassemble it, which is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation on the present invention. The specific structural and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0023] According to a specific embodiment of the utility model, an air guide device for connecting two inflatable products is provided, which can respectively connect the two inflatable products, a wire drawing mat and an air column, so as to realize the circulation of the air flow channel. When building an inflatable roof tent, the wire drawing mat and the air column are connected with the air guide device, the control valve is opened, and the air pump can be used to inflate the wire drawing mat and the air column at the same time to achieve rapid construction. The air column mentioned above can also be an ordinary inflatable stretched air bed. As long as the corresponding air valve is installed, the inflatable product can be connected to realize integrated inflation, which can effectively solve the problems of cumbersome use, difficult production and high labor costs. Among them, Figures 1 to 4 One specific embodiment is shown.

[0024] See also Figures 1 to 4 As shown, each inflatable product is provided with an air valve 1 and an air valve cover 2 for closing the air valve 1, and an elastic pressing structure 11 is provided in the middle of the air valve core of the air valve 1, and the elastic pressing structure 11 is connected to the air valve 1 to close and open the air valve 1. The air guide device for connecting two inflatable products includes a control valve 5, a hose 6 and a conversion joint 7, wherein at least two flow channels are provided on the control valve 5, and a clamping spring 51 is provided in each flow channel; the hose 6 and the conversion joint 7 are both provided in a number corresponding to the flow channels, wherein one end of the hose 6 is clamped in the clamping spring 51, and the other end is connected to the conversion joint 7.

[0025] Among them, the air valve 1 is also provided with a guide column, which protrudes toward the axis of the air valve core; one end of the conversion joint 7 is provided with a sleeve 71 for being inserted into the air valve 1, and the sleeve 71 is provided with a vertical groove 72 extending along the axial direction of the sleeve 71 and a horizontal groove 73 extending along the circumferential direction of the sleeve 71; the horizontal groove 73 is connected to the vertical groove 72.

[0026] When the conversion joint 7 is inserted along the axial direction of the air valve 1, the guide column is embedded in the vertical groove 72, and the conversion joint moves toward the air valve core and presses against the elastic pressing structure 11 to open the air valve core; when the conversion joint 7 is rotated along the circumferential direction of the air valve 1, the guide column is located in the horizontal groove 73, so that the position of the conversion joint 7 can be locked, so that the conversion joint 7 is firmly connected to the air valve 1.

[0027] Because there is a spring pressing structure in the middle of the valve core of the air valve 1, when inflating, the spring pressing structure is pressed to open the air valve 1, thereby inflating; and after the gas is fully inflated, the spring pressing structure is released, and the spring is restored and popped out under its elastic force, so that the air valve 1 is closed, and the gas is blocked and cannot leak out. Pressing the spring again can deflate.

[0028] Through the above technical solution, based on the matching structure of the guide column and the sleeve 71, the conversion joint 7 can be connected to the air valve 1 in a lockable manner. That is, when inflation is required, the sleeve 71 is firmly inserted into the air valve 1; and after the inflation is completed, the conversion joint 7 can be removed from the air valve 1 by reverse operation. Through the matching structure of the sleeve 71 and the air valve 1, the air guide device can be firmly connected to the inflatable product during inflation, and the reliability is good. Specifically, when applied, the conversion joint 7 at the end of the hose 6 can be connected to different inflatable products respectively, and then the control valve 5 is opened. In this way, the air guide device is formed into a gas circulation channel, which can allow the gas in different inflatable products to circulate. For example, during the use of the inflatable roof tent, the user finds that the air column 4 in the roof tent is not supportive enough and the hardness is insufficient. The air guide device can be used to connect the drawing pad 3 to replenish the air column 4.

[0029] Specifically, an air pump is used to inflate the wire drawing pad 3. When the wire drawing pad 3 is full, the air pump is turned off, and the control valve 5 on the air guide device is opened. The gas in the wire drawing pad 3 will flow to the air column 4 through the air guide device to realize the inflation of the air column 4. After the air column 4 is filled, the control valve 5 is closed, the air guide device is removed, and the air valve 1 is closed. In this way, the air pump can be used on the vehicle to inflate the air column 4 without getting off the vehicle, which improves the convenience of inflation for users. In addition, the structure is simple, and users can quickly install and disassemble it, which is practical. Through the design of the air guide device, the combination of the inflatable support pipe and the inflatable wire drawing pad can meet the user's needs for lightweight and convenient installation and storage, and the support pipe and the wire drawing pad can be detached for use. The tent with the support pipe can be used as a ground tent, and the wire drawing pad can also be used as a camping mattress, which increases the applicable scenarios of the product and provides more convenient options for users, with good flexibility and practicality.

[0030] It should be noted that the air valve 1 in the present disclosure is a universal air valve 1 for brushed fabrics on the market. The air valve cover 2 is unscrewed and connected with the conversion joint 7 to inflate. The elastic pressing structure 11 is also a prior art.

[0031] In the present disclosure, the inner diameter of the hose 6 is 8 mm, and the inner diameter of the flow passage of the control valve 5 is 8 mm.

[0032] The control valve 5 is a valve in the prior art, which can control the circulation and stop of gas. The control valve 5 has the letters S and O on its knob, and the valve can be opened for ventilation by rotating it counterclockwise.

[0033] In addition, in the present disclosure, Figures 1 to 3 As shown, the control valve 5 is provided with two flow channels, and the hose 6 and the conversion joint 7 are provided in two corresponding groups. The air guide device composed in this way can realize the air guide between two inflatable products.

[0034] In other embodiments, the control valve 5 can also be configured as three flow channels, and correspondingly, the hose 6 and the conversion joint 7 are configured as three corresponding groups. The air guide device thus configured can achieve air guide between three inflatable products.

[0035] It should be noted that the specifications of the hose 6 and the conversion joint 7 can be flexibly configured according to actual use requirements. As for the control valve 5, it is correspondingly set as a three-way valve. In this regard, those skilled in the art can match commercially available products according to requirements, or choose according to requirements.

[0036] In an embodiment provided by the present disclosure, a connection column 61 is provided at one end of the hose 6, a stud 74 is provided on the conversion joint 7, and the connection column 61 is threadedly connected to the stud 74. In this way, the hose 6 and the conversion joint 7 can be quickly connected, and later assembly is also facilitated.

[0037] In order to allow the conversion joint 7 to be quickly and accurately connected to the air valve 1, the air valve 1 is provided with grooves corresponding to the guide column. When inserting the conversion joint 7, the vertical groove 72 can be aligned with the grooves, and then pressed down, so that the conversion joint 7 can be pressed in along the axial direction and press against the spring pressing structure. Based on the setting of the grooves, the conversion joint 7 can be quickly aligned to improve the connection efficiency.

[0038] See also Figure 4 As shown, the conversion joint 7 is provided with a plurality of ridges 75, and the ridges 75 are evenly spaced along the circumferential direction of the conversion joint 7. This arrangement can increase the friction between the finger and the conversion joint 7, prevent sweating and slipping, and is beneficial to the stable operation of the conversion joint 7.

[0039] In an embodiment provided by the present disclosure, the outer surface of the ridge 75 is formed into a curved surface. This arrangement can increase the friction when the fingers hold the conversion joint 7, improve the comfort when holding, and reduce the frustration of the fingers.

[0040] Finally, it should be noted that the utility model is not limited to the above optional implementations, and anyone can derive other various forms of products under the inspiration of the utility model. The above specific implementations should not be understood as limiting the scope of protection of the utility model. The scope of protection of the utility model shall be based on the definition in the claims, and the description can be used to interpret the claims.
