Description

Technical Field

[0001] This utility model relates to the field of connection device technology, specifically a universal connection device for a gas cylinder valve. Background Technology

[0002] The universal connector for gas cylinder valves is a flexible connection component used between the outlet valve of a gas cylinder and the gas-using equipment / pipeline. Its core function is to solve the problem of misalignment in spatial position and direction between the outlet of the gas cylinder valve and the gas-using end interface through an adjustable connection structure, thus achieving "multi-directional adaptation and stable sealing connection".

[0003] Traditional universal joints mostly support rotation adjustment in only one dimension, either horizontal or vertical, and cannot achieve "horizontal + vertical" dual-dimensional linkage adjustment. They are difficult to adapt to the complex layout of the cylinder valve outlet direction and the interface position of the gas-using equipment, and cannot meet the connection requirements of large-angle offset scenarios, which greatly reduces the functionality of cylinder valve connection. Utility Model Content

[0004] The purpose of this invention is to provide a universal connection device for a gas cylinder valve, which has the advantage of quick rotation and adjustment connection, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A universal connection device for a gas cylinder valve includes a connecting pipe, a supporting horizontal plate fixedly installed at the lower end of the connecting pipe, a first adjusting component for adjusting the connection direction by lateral rotation at the lower end of the supporting horizontal plate, a vertical mounting plate fixedly installed at the side end of the first adjusting component, and a second adjusting component for adjusting the connection direction by vertical rotation at the side end of the vertical mounting plate. The first adjusting component includes an outer fixing sleeve fixedly installed at the lower end of the supporting horizontal plate and connected to the bottom end of the connecting pipe, and an arc-shaped adjusting cylinder rotatably connected to the lower end of the outer fixing sleeve.

[0006] Preferably, side protective plates are fixedly connected to both sides of the lower end of the supporting cross plate, and upper fixing rings are fixedly connected to the inner side of the side protective plates.

[0007] It is worth noting that: the upper fixing collar is fixed to the inside of the side protective plate, and cooperates with the lower fixing collar to form an upper and lower positioning structure, providing an installation benchmark for the protective outer sleeve and ensuring the coaxiality of the protective outer sleeve; at the same time, an adjustment locking groove is opened to provide a locking benchmark for the locking pin, so as to achieve precise positioning after adjustment; however, it should be noted that the opening position of the adjustment locking groove must be aligned with the adjustment locking groove of the lower fixing collar, and the groove diameter must match the locking pin to avoid jamming or excessive gap during locking.

[0008] Preferably, an adjusting rotating block is fixedly connected to the outer side of the arc-shaped adjusting drum, and a lower fixing ring is fixedly connected to the inner side of the side protective plate.

[0009] It is worth noting that: the adjusting rotating block is fixed on the outside of the arc-shaped adjusting cylinder and slides in conjunction with the limiting rotating groove of the protective outer sleeve, limiting the rotation trajectory of the arc-shaped adjusting cylinder and preventing deviation during lateral adjustment; a positioning mounting hole is opened inside, which cooperates with the adjusting locking groove and locking pin to fix the angle after lateral adjustment and ensure connection stability; however, it should be noted that the diameter of the positioning mounting hole must be precisely matched with the locking pin to ensure that there is no looseness after locking.

[0010] Preferably, a protective outer sleeve is fixedly connected between the upper fixed sleeve and the lower fixed sleeve, and a limiting rotation groove is opened inside the protective outer sleeve to slide and connect with the adjusting rotating block.

[0011] It is worth noting that: the limiting rotation groove, as a sliding guide structure for the adjusting rotating block, defines the lateral rotation range of the arc-shaped adjusting drum, preventing excessive rotation from causing the adjusting hose to twist or the connection parts to be damaged by force; at the same time, it limits the radial displacement of the adjusting rotating block to avoid wobbling during lateral adjustment and ensure connection accuracy; however, it should be noted that the length of the limiting rotation groove should be reasonably set according to the design adjustment angle to ensure that it meets the angle requirements of the usage scenario.

[0012] Preferably, the upper and lower fixed sleeves are provided with adjustment and locking grooves, the adjusting rotating block is provided with a positioning and mounting hole, and the adjustment and locking grooves and the positioning and mounting hole are detachably connected with locking pins on the outside.

[0013] It is worth noting that the locking pin is a detachable connection between the adjusting locking groove and the positioning mounting hole. It is the core component for fixing the lateral adjustment angle and achieves quick locking through mechanical insertion, making it easy to operate. However, it is important to select high-strength, corrosion-resistant materials, such as stainless steel, to avoid rusting or breakage after long-term use.

[0014] Preferably, a connecting plate is fixedly connected to the upper end of the vertical mounting plate, a linkage rotating plate is fixedly connected to the upper end of the connecting plate, a fixing ring is fixedly connected to the upper end of the supporting horizontal plate, an adjustment mounting groove is provided inside the fixing ring, a fixing mounting hole is provided through the linkage rotating plate, and a fixing pin is detachably connected to the outside of the adjustment mounting groove and the fixing mounting hole.

[0015] It is worth noting that the fixed pin can detachably connect the adjustment mounting slot and the fixed mounting hole. It is the core component for fixing the vertical adjustment angle. It is simple and quick to operate, and it is easy to quickly lock and adjust the vertical angle. However, it is necessary to select high-strength materials to prevent breakage or deformation.

[0016] Preferably, the second adjustment assembly includes fixed side plates fixedly installed at both ends of the outer side of the vertical mounting plate, a set of fixed side plates with adjustment knobs rotatably connected to their side ends, and an adjustment hose fixedly installed at the side end of the arc-shaped adjustment drum.

[0017] It is worth noting that the regulating hose connects the arc-shaped regulating drum to the docking pipe, providing a flexible channel for gas delivery and adapting to the vertical rotation adjustment of the second regulating component, avoiding rotation restriction or pipe damage caused by rigid connection; however, it is necessary to select materials that are resistant to high pressure, corrosion, and aging, and are suitable for the properties of the gas in the cylinder.

[0018] Preferably, a rotating rod is fixedly installed on the side of the adjusting knob, an adjusting rotating sleeve is fixedly connected to the outside of the rotating rod, an auxiliary rotating rod is fixedly installed on the outside of the adjusting rotating sleeve, a limiter is fixedly installed on the side of the auxiliary rotating rod, and a connecting pipe is fixedly installed on the outside of the adjusting rotating sleeve.

[0019] It is worth noting that the connecting pipe, as the connecting component between the device and the gas-consuming equipment / downstream pipeline, directly bears the gas output function; however, it is necessary to ensure that the interface of the connecting pipe is equipped with a standard connection structure, such as threads or flanges, to facilitate connection with the gas-consuming equipment.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the first adjustment component can adjust the connection direction by rotating according to the lateral positional deviation between the cylinder valve outlet and the gas-using end interface, allowing the device to adapt to different lateral installation layouts. This overcomes the limitation of traditional hard connections requiring strict lateral alignment, improving installation flexibility and enabling docking without readjusting the lateral position of the cylinder or gas-using equipment. The second adjustment component can adjust the connection direction by vertical rotation to address the vertical positional deviation between the cylinder valve outlet and the gas-using end interface, forming a two-dimensional adjustment with the first component. This completely solves the problem of poor adaptability of traditional single-dimensional adjustment, and can handle situations where interfaces are misaligned in multiple directions in complex installation scenarios. This enhances the device's adaptability to different installation environments, eliminates the need for strict calibration of the vertical position of the cylinder and gas-using equipment, reduces installation difficulty, and ensures the stability of the connection after adjustment, avoiding the risk of leakage caused by vertical vibration.
