Description

Technical Field

[0001] This utility model belongs to the technical field of inflation equipment, and specifically relates to an inflation support structure for high-pressure gas cylinders. Background Technology

[0002] In the field of high-pressure gas storage and use, small high-pressure gas cylinders are widely used due to their convenience. However, small high-pressure gas cylinders using Tr21x4 threads as the cylinder interface reveal several problems when connected to a pressure reducing valve for stable pressure output: Sealing and gas path continuity issues: Currently, the common method is to use a cylinder end face seal and a top-pressure valve to connect the high-pressure gas path, but the timing of sealing and valve opening / closing is difficult to control precisely. During cylinder assembly and disassembly, high-pressure gas leakage is very likely, producing a sharp gas flow noise, which not only wastes gas but may also interfere with the operating environment. Operational safety and user experience issues: If the user directly holds the pressure reducing valve and cylinder body for screwing operations, their hand will be too close to the pressure relief point; if high-pressure gas is accidentally ejected, it may cause injury to the user, and the sharp gas flow noise will also provide a poor user experience, reducing operational comfort and safety. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this application provides a sealing device for an inflation device to solve the above-mentioned technical defects.

[0004] This utility model proposes an inflation support structure for high-pressure gas cylinders, including a pressure reducing valve, a pressure reducing valve bracket, and a fixed base. The pressure reducing valve is fixedly mounted on the pressure reducing valve bracket, which is rotatably mounted on the upper part of the fixed base. The lower part of the fixed base has a U-shaped groove, the size of which is adapted to the neck diameter of the high-pressure gas cylinder. After the high-pressure gas cylinder is connected to the pressure reducing valve, it can rotate with the pressure reducing valve bracket and enter the U-shaped groove. The open end of the U-shaped groove is equipped with a bottle mouth anti-detachment mechanism. This application provides an inflation support structure for high-pressure gas cylinders. Through the rotatable connection between the pressure reducing valve bracket and the fixed base, convenient installation and fixation of the high-pressure gas cylinder are achieved. The design of the U-shaped groove, adapted to the neck diameter of the high-pressure gas cylinder, ensures that the cylinder can be stably fixed after installation, preventing the cylinder from shaking or shifting. The bottle mouth anti-detachment mechanism further enhances the fixing effect of the cylinder, preventing the cylinder from accidentally falling off during use and improving safety.

[0005] In some specific embodiments, the pressure reducing valve bracket is connected to the upper part of the fixed base via a spring hinge. Connecting the pressure reducing valve bracket and the fixed base via the spring hinge allows the pressure reducing valve bracket to automatically flip up when no gas cylinder is installed, facilitating the installation of the gas cylinder.

[0006] In some specific embodiments, the spring hinge is configured to allow the pressure reducing valve bracket to flip up to a preset angle under the action of the torsion spring when the high-pressure gas cylinder is not installed, and to flip down under load after the high-pressure gas cylinder is installed. The torsion spring action of the spring hinge keeps the pressure reducing valve bracket in the flipped-up state when the gas cylinder is not installed, facilitating the user's installation and removal of the gas cylinder. After the gas cylinder is installed, the pressure reducing valve bracket can flip down under load, and the spring hinge can also provide preload force to help fix the high-pressure gas cylinder and prevent the pin from slipping out, ensuring that the high-pressure gas cylinder is stably fixed in the U-shaped slot, improving the convenience and safety of operation.

[0007] In some specific embodiments, the high-pressure gas cylinder and the pressure reducing valve are connected by a threaded connection. This arrangement ensures the sealing and connection strength between the gas cylinder and the pressure reducing valve, preventing gas leakage. The threaded connection is simple and reliable, facilitating quick installation and removal of the gas cylinder by the user.

[0008] In some specific embodiments, the anti-detachment mechanism consists of a pin located at the open end of the U-shaped slot and a corresponding pin seat. The cooperation between the pin and the pin seat locks the open end of the U-shaped slot, preventing the gas cylinder from accidentally detaching during use.

[0009] In some specific embodiments, a pull ring is provided at one end of the pin. This feature allows users to quickly pull out or insert the pin, simplifying the operation process.

[0010] In some specific embodiments, the opening of the U-shaped slot is provided with outwardly flared guide grooves on both sides. This feature facilitates the smooth entry of the gas cylinder into the U-shaped slot.

[0011] In some specific embodiments, an air outlet is provided on one side of the pressure reducing valve, and the air outlet is connected to the air injection head via an air pipe. This feature expands the application scenarios of the bracket.

[0012] In some specific embodiments, a spring is provided in the middle of the fixed base, which abuts against the pressure reducing valve bracket after it is flipped down. The spring in the middle of the fixed base provides a buffer when the pressure reducing valve bracket is flipped down, reducing the impact force when the bracket is flipped down. The preload of the spring ensures the stability of the pressure reducing valve bracket after it is flipped down, preventing the bracket from shaking or loosening.

[0013] In some specific embodiments, the mounting base is fixed to a vertical or horizontal plane by bolts. This arrangement makes it suitable for a variety of usage environments, enhancing the versatility of the bracket.

[0014] Compared with the prior art, the beneficial results of this utility model are as follows:

[0015] This inflatable support structure significantly improves the safety and convenience of high-pressure gas cylinder operation through an innovative design of a spring-hinged, foldable pressure-reducing valve support and a fixed base. The spring hinge automatically tilts the support upwards when unloaded for easy cylinder docking, and tilts downwards under load. The spring hinge also provides preload to help secure the high-pressure gas cylinder and prevent the pin from slipping, achieving stable support. The U-shaped groove precisely constrains the bottleneck diameter, and together with the pin-type anti-detachment mechanism and guide groove, it ensures the reliability of the gas cylinder fixation while simplifying the disassembly and assembly process. The pressure-reducing valve structure facilitates support assembly and functional expansion. Bolts allow for vertical / horizontal plane installation, accommodating different scenario requirements. Threaded connections and anti-rotation locking designs ensure gas circuit sealing safety. The overall solution achieves systematic optimization in terms of operational safety, structural stability, universal compatibility, and ease of use. Attached Figure Description

[0021] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0022] This utility model proposes an inflation support structure for high-pressure gas cylinders. Figure 1 A schematic diagram of an inflation support structure for a high-pressure gas cylinder according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the main structure of this support includes a fixed base 1 and a pressure reducing valve bracket 2. The fixed base 1 serves as an integral support structure, and its upper part is connected to the pressure reducing valve bracket 2 via a spring hinge 4, allowing the pressure reducing valve bracket 2 to rotate flexibly. The lower part of the fixed base 1 is provided with a U-shaped groove 5, the size of which is adapted to the high-pressure gas cylinder 7 (see reference). Figure 2 and Figure 3 The bottleneck diameter (as shown in the diagram) can constrain the high-pressure gas cylinder 7 from three directions, ensuring its stability. The opening end of the U-shaped slot 5 is equipped with an anti-detachment mechanism to prevent the high-pressure gas cylinder 7 from accidentally detaching during use, thus improving operational safety. The pressure reducing valve 3 is fixedly installed on the pressure reducing valve bracket 2, providing core component support for gas transmission.

[0023] In a specific embodiment, the spring hinge 4 is configured to allow the pressure reducing valve bracket 2 to flip up to a preset angle under the action of the torsion spring when the high-pressure gas cylinder 7 is not installed. This preset angle ranges from 20° to 160°. After the high-pressure gas cylinder 7 is installed, it flips down under load and falls into the U-shaped slot 5. This setting facilitates the installation and removal of the gas cylinder by the user. After the high-pressure gas cylinder 7 is installed, the pressure reducing valve bracket 2 can flip down under load, ensuring that the high-pressure gas cylinder 7 is stably fixed in the U-shaped slot 5, improving the convenience and safety of operation. In a specific example, the spring hinge 4 can be a shaft spring, which can achieve precise function by utilizing its torsional characteristics: when the high-pressure gas cylinder 7 is not installed, the torsion of the shaft spring drives the pressure reducing valve bracket 2 to flip up to the preset angle, leaving space for the docking of the high-pressure gas cylinder 7 and the pressure reducing valve 3, facilitating quick assembly; after the high-pressure gas cylinder 7 is installed, the shaft spring, under the action of load, allows the pressure reducing valve bracket 2 to flip down smoothly, ensuring that the high-pressure gas cylinder 7 smoothly enters the U-shaped slot 5 for fixation.

[0024] In a specific embodiment, the anti-detachment mechanism consists of a pin 6 located at the open end of the U-shaped slot 5 and a corresponding pin seat. Preferably, one end of the pin 6 is provided with a pull ring, which allows for easier insertion and removal of the pin seat 6. The anti-detachment mechanism uses the pin seat 6 in conjunction with the pin seat. After the pin seat 6 is inserted, it prevents the high-pressure gas cylinder pin seat 7 from detaching from the pin seat 5 in the U-shaped slot, locking the gas cylinder position during inflation and effectively reducing the risk of accidental detachment, thus enhancing safety. The U-shaped slot 5 has outwardly flared guide grooves on both sides of its opening. These grooves guide the pin seat 7, making it easier to align the bottleneck of the high-pressure gas cylinder pin seat 7 and slide it into the U-shaped slot 5, reducing manual alignment time and optimizing the installation experience.

[0025] In a specific embodiment, the pressure reducing valve 3 is generally rectangular in shape, which facilitates its assembly with the pressure reducing valve bracket 2. The two can be fastened together by bolts to stably mount the pressure reducing valve 3 on the pressure reducing valve bracket 2.

[0026] Figure 2 This diagram illustrates the tilted cylinder replacement configuration of a high-pressure gas cylinder inflation support structure according to a specific embodiment of the present invention; as shown... Figure 2 As shown, when the high-pressure gas cylinder 7 is not installed, the pressure reducing valve bracket 2 is automatically flipped up to a preset angle by the action of the spring hinge 4. At this time, the U-shaped slot 5 and the pressure reducing valve 3 form an open space, which makes it easy for the operator to connect the high-pressure gas cylinder 7 and the pressure reducing valve 3 by thread, simplifying the docking process when changing cylinders and improving the convenience of operation.

[0027] In a specific embodiment, the fixed base 1 is fixed to a vertical or horizontal plane by bolts, which can flexibly adapt to different installation scenarios (such as workbench, wall, etc.), thereby making the overall bracket stable and reliable.

[0028] In a specific embodiment, the interface of the high-pressure gas cylinder 7 is a Tr21*4 threaded interface. The gas inlet of the pressure reducing valve 3 is directly screwed through this interface. The operator can hold the cylinder body and perform the screwing operation with one hand, avoiding the situation where the hand is too close to the pressure relief point if the pressure reducing valve 3 and the high-pressure gas cylinder 7 are screwed on at the same time. If the high-pressure gas is accidentally ejected, it may cause injury to the user. At the same time, the sharp airflow sound will also bring an unpleasant experience to the user, reducing the comfort and safety of operation.

[0029] Figure 3 A schematic diagram of the working state of the inflation support structure of a high-pressure gas cylinder according to a specific embodiment of the present invention is shown, as follows: Figure 3As shown, after the high-pressure gas cylinder 7 is connected to the pressure reducing valve 3, it rotates into the U-shaped slot 5 along with the pressure reducing valve bracket 2. The pin 6 is inserted into the corresponding position to lock the high-pressure gas cylinder 7. The spring hinge 4 also provides pre-tightening force to help fix the high-pressure gas cylinder 7 and prevent the pin 6 from slipping out, ensuring that it is stable and does not fall off. At the same time, the gas outlet 8 on one side of the pressure reducing valve 3 is connected to the gas filling head 10 through the gas pipe 9, forming a complete gas path. This allows the gas in the high-pressure gas cylinder 7 to be stably transmitted to the gas filling head 10 to meet the filling requirements. During operation, the entire structure achieves safe and stable gas transmission through the cooperation of various components.

[0030] In a specific embodiment, a spring sheet can also be provided in the middle of the fixed base 1, which can abut against the pressure reducing valve bracket 2 after it is flipped down. This provides a buffering effect when the pressure reducing valve bracket 2 is flipped down, reducing the impact force when the pressure reducing valve bracket 2 is flipped down. The preload of the spring sheet ensures the stability of the pressure reducing valve bracket 2 after it is flipped down, preventing the pressure reducing valve bracket 2 from shaking or loosening.

[0031] The high-pressure gas cylinder inflation support structure of this application utilizes components such as a fixed base 1, a pressure reducing valve bracket 2, a pressure reducing valve 3, a spring hinge 4, a U-shaped slot 5, and a pin 6 working in concert. Regarding operational safety, the anti-detachment mechanism, such as the pin 6, prevents the gas cylinder from falling out, while the spring hinge and spring plate enhance stability and reduce accidents. Secondly, it offers greater operational convenience; the spring hinge automatically flips up and down, allowing users to easily assemble the high-pressure gas cylinder 7 with one hand. The gas connection is reliable; the threaded connection and gas tube injection head ensure gas transmission, allowing for on-the-fly inflation operations using the injection head 10 against the structure requiring inflation, such as for liquid filling.

Any reference numerals in the claims should not be considered as limiting the scope.
