[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 The utility model provides a gas pipeline pressure regulating and metering device that is easy to disassemble and assemble, including a base assembly 1, an A connecting assembly 2 is arranged on the base assembly 1, a pressure regulating and metering pipeline 3 and a B connecting assembly 4 are arranged on the base assembly 1, and the B connecting assembly 4 connects the base assembly 1 and the pressure regulating and metering pipeline 3;

[0027] Among them, the B connecting component 4 includes a clamping ring 41, an insertion block 42, an insertion rod 43, a fixed block 45, a rotating block 46, a B ratchet 47, a B ratchet 48 and a rotating shaft 49. The fixed block 45 is installed on the base component 1. The rotating block 46, the B ratchet 47, the B ratchet 48 and the rotating shaft 49 are each provided with two. The two rotating blocks 46 are installed on the fixed block 45 through the rotating shaft 49. The two B ratchets 47 are respectively installed at one end of the rotating shaft 49. The two B ratchets 48 are both installed at one end of the fixed block 45. The two B ratchets 47 and the B ratchet 48 are clamped. The insertion block 42 and the insertion rod 43 are each provided with two. The two insertion rods 43 are both installed at the lower end of the clamping ring 41. The two insertion blocks 42 are respectively installed at the lower end of the insertion rod 43. The two insertion blocks 42 and the insertion rod 43 all penetrate and extend out of the surface of the base component 1, and the insertion block 42 is arranged inside the rotating block 46.

[0028] Specifically, when fixing the pressure regulating and metering pipeline 3, the pressure regulating and metering pipeline 3 can be placed on the base assembly 1 first, and then the insertion block 42 and the insertion rod 43 are penetrated and set on the base assembly 1. Since the base assembly 1 is provided with a fixed block 45, and the fixed block 45 is provided with a rotating block 46, the fixed block 45 and the rotating block 46 are rotatably connected through the rotating shaft 49. Since the rotating block 46 is provided with an arc groove, the insertion block 42 can be inserted into the rotating block 46 from the top of the rotating block 46. The inner wall of the rotating block 46 is squeezed by the insertion block 42, so that the rotating block 46 can be driven to rotate. Through the simultaneous movement of the two groups of rotating blocks 46, the insertion block 42 can be clamped by the rotating block 46, so that the clamping ring 41, the insertion block 42 and the insertion rod 43 can be stably arranged, and the pipeline of the pressure regulating and metering pipeline 3 is arranged on the clamping ring 4 1 and the base assembly 1, so that the pressure regulating and metering pipeline 3 can be stably arranged, and since the B ratchet 47 is arranged at one end of the rotating shaft 49, and the B ratchet 48 is arranged at one end of the fixed block 45, the B ratchet 47 and the B ratchet 48 are arranged on the same side, the B ratchet 48 can be clamped to the B ratchet 47 at this time, so that it can be avoided that the insertion block 42 is separated from the inside of the rotating block 46 during use, thereby causing the pressure regulating and metering pipeline 3 to fall off, and when the pressure regulating and metering pipeline 3 needs to be removed, the B ratchet 48 can be rotated to release the clamping of the B ratchet 47 and the B ratchet 48, so that the rotating block 46 can be rotated in the opposite direction at this time. By rotating the rotating block 46 in the opposite direction, the insertion block 42 can be taken out from the rotating block 46, so that the clamping ring 41, the insertion block 42 and the insertion rod 43 can be separated from the base assembly 1, and the pressure regulating and metering pipeline 3 can be taken out.

[0029] In this embodiment, the base assembly 1 includes a base 11 , an A fixing rod 12 , a B fixing rod 13 and a C fixing rod 14 , and the A fixing rod 12 , the B fixing rod 13 and the C fixing rod 14 are all installed on the base 11 .

[0030] Specifically, in order to stably set the pressure regulating and metering pipeline 3 during actual use, a fixing rod A 12 , a fixing rod B 13 and a fixing rod C 14 are provided on the base 11 , so that multiple pipelines of the pressure regulating and metering pipeline 3 can be fixed.

[0031] In this embodiment, a plurality of B connecting components 4 are provided, and the plurality of B connecting components 4 are respectively mounted on the A fixing rod 12 , the B fixing rod 13 and the C fixing rod 14 .

[0032] Specifically, in order to fix the multiple pipes of the pressure regulating and metering pipeline 3, a B connecting component 4 is provided on the A fixing rod 12, the B fixing rod 13 and the C fixing rod 14. The B connecting component 4 can be used to fix the multiple pipes of the pressure regulating and metering pipeline 3, so that the pressure regulating and metering pipeline 3 can be stably set.

[0033] In this embodiment, the pressure regulating and metering pipeline 3 includes a plurality of pipelines, and the plurality of pipelines are respectively arranged on the A fixing rod 12 , the B fixing rod 13 and the C fixing rod 14 .

[0034] Specifically, during actual use, since the gas pressure is regulated and metered in different pipelines respectively, the pressure regulating and metering pipeline 3 is provided with a plurality of pipelines in addition to the pressure regulating valve and the metering meter. In order to stably set the pressure regulating and metering pipeline 3, the plurality of pipelines can be fixed, and when disassembling, the plurality of pipelines can be released, and then the pressure regulating and metering pipeline 3 can be disassembled.

[0035] In this embodiment, the B connecting assembly 4 further includes a buffer member 44 . The buffer member 44 is disposed on the B fixing rod 13 . The insertion rod 43 penetrates through and extends out of the surface of the buffer member 44 .

[0036] Specifically, in order to ensure that when the pressure regulating and metering pipeline 3 is set on the base assembly 1, the surface of the base assembly 1 will not scratch the surface of the pipeline in the pressure regulating and metering pipeline 3, a buffer member 44 can be set on the base assembly 1, and the buffer member 44 can be used to support the pipeline and thus protect the pipeline.

[0037] In this embodiment, the A connecting component 2 includes an A screw rod 21, an A ratchet 22 and an A ratchet 23. The A ratchet 23 is installed on the base 11. The A screw rod 21 passes through and extends out of the surface of the base 11. The A ratchet 22 is installed at the upper end of the A screw rod 21. The A ratchet 22 and the A ratchet 23 are clamped.

[0038] Specifically, during specific use, since the devices are all set on the base 11, the base 11 itself needs to be fixed relatively stably to prevent the base 11 from tipping over during subsequent use. At this time, the A screw rod 21 can be set through the base 11, and an A ratchet 22 is set at the upper end of the A screw rod 21, and an A ratchet 23 is set on the surface of the base 11. By threading the A screw rod 21 on the ground, the A ratchet 23 and the A ratchet 22 can be clamped together to prevent the A screw rod 21 from rotating in the opposite direction, so that the A screw rod 21 can be stably connected.

[0039] In this embodiment, the clamping ring 41 is configured as an arc-shaped structure, and the inserting block 42 is configured as a hemispherical structure.

[0040] Specifically, during actual use, in order to enable the clamping ring 41 to fit the pipe more closely and thus improve the fixing effect, the clamping ring 41 can be set to an arc-shaped structure, and in order to enable the insertion block 42 to be fixed by the rotating block 46, the insertion block 42 is set to a hemispherical structure, so that the upper end of the insertion block 42 can be clamped by the rotating block 46 when fixed, and the arc-shaped surface of the insertion block 42 can squeeze the rotating block 46, so that the rotating block 46 rotates.

[0041] The working principle and use process of the utility model are as follows: when installing and disassembling the pressure-regulating and metering pipeline 3, the pressure-regulating and metering pipeline 3 can be first set on the base assembly 1, and then the two can be connected through the B connecting assembly 4. When connecting, the insertion block 42 and the insertion rod 43 can be inserted into the base assembly 1, and the insertion block 42 can be set inside the rotating block 46, and it can be fixed by the rotating block 46, and then the B ratchet 47 and the B ratchet 48 can be engaged, so that the rotating block 46 cannot rotate in the opposite direction. At this time, the pressure-regulating and metering pipeline 3 can be stably fixed, and when disassembling the pressure-regulating and metering pipeline 3, the B ratchet 48 can be rotated to release the fixation of the B ratchet 47 and the B ratchet 48. At this time, the rotating block 46 can be rotated in the opposite direction, and the insertion block 42 can be taken out from the rotating block 46. After the insertion block 42 and the insertion rod 43 are completely separated from the base assembly 1, the pressure-regulating and metering pipeline 3 can be disassembled.

[0042] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
