Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pressure reducing equipment, and in particular relates to a pressure reducer which can be quickly installed on a dissolved acetylene gas cylinder. Background Art
[0002] Dissolved acetylene cylinders require a pressure reducer to reduce the high-pressure gas stored in the cylinder to low-pressure gas, and the required working pressure should be kept stable from beginning to end. The traditional pressure reducer interface is not designed with fool-proof joints. When it is installed with dissolved acetylene cylinders, the thread of the pipe joint is prone to slipping when the thread head is not aligned horizontally with the dissolved acetylene cylinder interface due to the long pressure reducer joint part. Therefore, the operator needs to manually debug the joint before operation to avoid loose rotation and ejection. This operation method is not ideal for the quick installation requirements. To this end, we propose a pressure reducer that can be quickly installed on dissolved acetylene cylinders. Utility Model Content
[0003] The utility model provides a pressure reducer which can be quickly installed on a dissolved acetylene gas cylinder and has the characteristics of fool-proof quick docking.
[0004] The utility model provides the following technical solutions: a pressure reducer that can be quickly installed on a dissolved acetylene gas cylinder, comprising a pressure reducer main body, joint assemblies are arranged on both sides of the pressure reducer main body, a fool-proof connection assembly is sleeved on the outer side of the joint assembly, the fool-proof connection assembly is used for horizontal guidance when the pressure reducer is docked with the threaded interface of the gas cylinder, the fool-proof connection assembly comprises a fool-proof threading seat, a buffer column head, a sealing composite guide component and a horizontal access guide column, one end of the sealing composite guide component is fixedly connected to the fool-proof threading seat, the buffer column head is fixedly connected to the end of the fool-proof threading seat away from the sealing composite guide component, the buffer column head is used to increase the outer side sealing after the joint assembly is docked with the threaded interface of the gas cylinder, the horizontal access guide column is fixedly connected to the inner side of the buffer column head, and the sealing composite guide component and the horizontal access guide column are used for limiting the sliding path of the joint assembly when it is docked with the threaded interface of the gas cylinder.
[0005] Among them, the composite guide component of the cover includes a movable connecting piece, an interlocking mounting strip and an elastic compression piece. There are several movable connecting pieces. One side of the movable connecting piece is fixedly connected with the interlocking mounting strip. The interlocking mounting strip is snap-connected with the movable connecting piece. The elastic compression piece is fixedly connected between two adjacent movable connecting pieces.
[0006] There are several horizontal access guide pillars, which are distributed in a ring shape along the inner wall of the buffer column head.
[0007] Wherein, the joint assembly includes an input interface part and a pipe joint part, the input interface part is fixedly connected to the pipe joint part, the input interface part is fixedly connected to the input end of the pressure reducer body, the end of the sealing composite guide component away from the anti-foolproof socket is fixedly connected to the input interface part, and the pipe joint part is located on the inner side of the anti-foolproof socket.
[0008] Wherein, a directional slot is provided on one side of the movable connecting piece, and the embedded installation strip is engaged and connected with the movable connecting piece through the directional slot, and is used for engagement and limiting when the movable connecting pieces are close to each other.
[0009] The beneficial effects of the utility model are as follows: the setting of the horizontal access guide column provides a vertical guiding effect for the gas cylinder joint when it is inserted into the pipe joint part, so that in the process of the gas cylinder joint moving toward the pipe joint part, it first reaches the inner side of the anti-foolproof plug-in seat through the guidance of the horizontal access guide column. Because the inner cavity of the anti-foolproof plug-in seat is horizontal with the pipe joint part, before screwing the pipe joint part and the gas cylinder interface, the anti-foolproof plug-in seat pre-limits the plug-in part of the gas cylinder joint horizontally. At the same time, in the process of inserting and moving the gas cylinder joint toward the pipe joint part before screwing, the elastic compression part is contracted by dynamic pressure, so that the movable connecting piece and the engaging mounting strip are engaged with each other, so that the anti-foolproof plug-in seat and the gas cylinder interface still maintain a horizontal state after moving and contacting the pipe joint part, that is, one pushing action aligns the pipe joint part with the gas cylinder joint before screwing, avoiding slipping of the thread of the tube-gas cylinder joint caused by non-aligned screwing, and can be quickly installed while ensuring stability in use.

DETAILED DESCRIPTION
[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a pressure reducer that can be quickly installed on a dissolved acetylene gas cylinder, comprising a pressure reducer main body 1, joint components 2 are arranged on both sides of the pressure reducer main body 1, and a fool-proof connection component 3 is sleeved on the outer side of the joint component 2. The fool-proof connection component 3 is used for horizontal guidance when the pressure reducer is connected to the threaded interface of the gas cylinder. The fool-proof connection component 3 comprises a fool-proof threading seat 31, a buffer column head 32, a sealing composite guide component 33 and a horizontal access guide column 34. One end of the sealing composite guide component 33 is fixedly connected to the fool-proof threading seat 31, and the buffer column head 32 is fixedly connected to the end of the fool-proof threading seat 31 away from the sealing composite guide component 33. The buffer column head 32 is used to increase the outer sealing after the joint component 2 is connected to the threaded interface of the gas cylinder. The horizontal access guide column 34 is fixedly connected to the inner side of the buffer column head 32. The sealing composite guide component 33 and the horizontal access guide column 34 are used to limit the sliding path when the joint component 2 is connected to the threaded interface of the gas cylinder.
[0017] In this embodiment, in order to solve the problem that the existing quick-connect thread structure is prone to slipping when the thread head end is not horizontally aligned with the interface of the dissolved acetylene gas cylinder due to the long reducer joint part, the utility model provides a vertical guiding effect when the gas cylinder joint is inserted into the pipe joint part 22 through the setting of the horizontal access guide column 34. During the process of the gas cylinder joint moving to the pipe joint part 22, it first reaches the inner side of the foolproof insertion seat 31 through the guidance of the horizontal access guide column 34. Because the inner cavity of the foolproof insertion seat 31 is horizontal with the pipe joint part 22, before screwing the pipe joint part 22 and the gas cylinder interface, the foolproof insertion seat 31 pre-limits the horizontal insertion part of the gas cylinder joint. At the same time, when the gas cylinder joint is inserted into and moved toward the pipe joint part 22 before screwing, the elastic compression part 333 is contracted by dynamic pressure, so that the movable connecting piece 331 and the interlocking mounting strip 332 are interlocked with each other, so that the anti-foolproof plug-in seat 31 and the gas cylinder interface move and contact with the pipe joint part 22, while still maintaining a horizontal state, that is, one pushing action aligns the pipe joint part 22 and the gas cylinder joint before screwing, avoiding slipping of the thread of the tube gas cylinder joint caused by non-aligned screwing, and ensuring stability in use while ensuring quick installation.
[0018] The cover composite guide component 33 includes a movable connecting piece 331, an interlocking mounting strip 332 and an elastic compression piece 333. There are several movable connecting pieces 331. One side of the movable connecting piece 331 is fixedly connected with the interlocking mounting strip 332. The interlocking mounting strip 332 is snap-connected with the movable connecting piece 331. An elastic compression piece 333 is fixedly connected between two adjacent movable connecting pieces 331.
[0019] A directional slot 334 is provided on one side of the movable connecting piece 331 , and the engaging mounting strip 332 is engaged with the movable connecting piece 331 through the directional slot 334 , so as to be used for engagement and limiting when the movable connecting pieces 331 are close to each other.
[0020] In this embodiment, after the installation is completed, the position of the movable connecting piece 331 is limited by the mutual engagement of the engaging mounting strip 332 and the directional card slot 334, and the movable connecting piece 331 remains parallel to the pipe joint portion 22. At this time, the buffer column head 32 and the movable connecting piece 331 are sleeved on the outside of the pipe joint portion 22 and the gas cylinder interface. The movable connecting piece 331 in a contracted and composite state can be used as an outer protective layer of the pipe joint portion 22 and the gas cylinder interface, so that the movable connecting piece 331 can not only serve as an installation guide, but also can isolate the pipe joint portion 22 and the gas cylinder interface. At the same time, when the pipe joint portion 22 and the gas cylinder interface are loosened and disassembled, the elastic compression member 333 can quickly return the movable connecting piece 331 to its original state through elastic resetting, without the need for manual resetting.
[0021] There are several horizontal access guide pillars 34 and they are distributed in a ring shape along the inner wall of the buffer column head 32. In the present embodiment, the horizontal access guide pillars 34 can reduce the contact surface between the buffer column head 32 and the gas cylinder interface, facilitate the insertion of the gas cylinder interface into the buffer column head 32, and at the same time, limit the parallel insertion requirement of the gas cylinder interface, keep the gas cylinder interface and the pipe joint part 22 in a parallel state before screwing together, and avoid the phenomenon of slipping of the pipe joint thread when screwing together when the thread head end is not horizontally aligned with the dissolved acetylene gas cylinder interface.
[0022] The joint assembly 2 includes an input interface part 21 and a pipe joint part 22. The input interface part 21 is fixedly connected to the pipe joint part 22. The input interface part 21 is fixedly connected to the input end of the pressure reducer body 1. The end of the sealing composite guide component 33 away from the anti-foolproof threading seat 31 is fixedly connected to the input interface part 21. The pipe joint part 22 is located on the inner side of the anti-foolproof threading seat 31.
[0023] In this embodiment, since the improvement of the utility model lies in the docking between the interface of the dissolved acetylene gas cylinder and the pressure reducer, the pressure reducing structure of the pressure reducer body 1 is not an innovative content of the utility model, but a well-known technology in the field. In this embodiment, the original principle of the pressure reducer body 1 is not repeated.
[0024] The working principle of the present invention is to insert the interface of the dissolved acetylene gas cylinder into the inner side of the buffer column head 32, so that the gas cylinder interface reaches the inner side of the anti-foolproof plug-in seat 31 through the guidance of the horizontal access guide column 34, so that the anti-foolproof plug-in seat 31 pre-limits the plug-in part of the gas cylinder joint horizontally, and then the pressure reducer body 1 continues to be pushed toward the direction of the gas cylinder interface, so that the elastic compression member 333 is contracted by dynamic pressure until the movable connecting piece 331 and the engaging mounting strip 332 are engaged with each other, and after the anti-foolproof plug-in seat 31 and the gas cylinder interface move and contact with the pipe joint part 22, that is, one pushing action makes the pipe joint part 22 and the gas cylinder joint align before screwing, ensuring quick installation while avoiding slipping of the thread of the pipe gas cylinder joint caused by non-aligned screwing, thereby improving the installation stability. After screwing, the buffer column head 32 and the movable connecting piece 331 can not only serve as installation guides, but also can isolate the pipe joint part 22 and the gas cylinder interface, thereby further improving the practicality.
