DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a pipeline installation structure of a gas detector includes a pipeline 1, a branch pipe 2 and a gas detector body 4, a connecting pipe 5 is fixedly connected to the bottom end of the gas detector body 4, and a connecting structure 8 is provided between the connecting pipe 5 and the branch pipe 2;

[0025] The connecting structure 8 includes a connecting ring 801, which is fixedly installed on the surface of the branch pipe 2. A connecting seat 804 is fixedly installed on the surface of the connecting pipe 5 near the bottom end. Slide grooves 805 are provided at the upper and lower ends of the connecting seat 804 near the front and rear sides. A movable rod 802 is slidably installed in the slide groove 805. A clamping seat 803 is rotatably installed at the bottom end of the movable rod 802. A rotating rod 1 806 is fixedly installed at a position near the movable rod 802 inside the connecting seat 804. A ratchet 807 is rotatably installed on the surface of the rotating rod 1 806. A mounting rod 808 and a rotating rod 2 810 are respectively fixedly installed on one side of the ratchet 807 inside the connecting seat 804. A limiting rod 811 is rotatably installed on one end of the surface of the rotating rod 2 810. A spring 809 is fixedly installed between the mounting rod 808 and the limiting rod 811. An adjusting rod 812 is fixedly installed on the top of the limiting rod 811. A plurality of adjusting grooves 813 are provided on one side of the movable rod 802.

[0026] In this embodiment, a valve 3 is fixedly mounted on the branch pipe 2 , and a mounting groove 6 is formed at the bottom end of the connecting pipe 5 .

[0027] The valve 3 is used to regulate whether the gas in the pipeline 1 passes through the branch pipe 2. It can be sealed when not being tested. The installation groove 6 has the effect of alignment installation and is more stable.

[0028] In this embodiment, the installation groove 6 is compatible with the branch pipe 2 , and a sealing ring 7 is fixedly installed inside the installation groove 6 .

[0029] The mounting groove 6 can be mounted on the top of the branch pipe 2 , and the sealing ring 7 plays a sealing role, so that the gas will not leak through the connection between the mounting groove 6 and the branch pipe 2 .

[0030] In this embodiment, the ratchet 807 and the adjustment slot 813 are adaptably matched, and the limiting rod 811 is in close contact with the ratchet 807 .

[0031] The ratchet 807 and the adjustment slot 813 limit the movable rod 802 so that the movable rod 802 will not move downward under the action of gravity. The limiting rod 811 limits the ratchet 807 so that the ratchet 807 can only rotate counterclockwise.

[0032] In this embodiment, the holder 803 is an "L"-shaped structure, and the contact surface between the ratchet 807 and the rotating rod 1 806 is an "H"-shaped structure.

[0033] The "L"-shaped structure plays a limiting role, so that the socket 803 can be clamped to the bottom end of the connecting ring 801, and the "H"-shaped structure plays a limiting role, so that the ratchet 807 will not move along the surface of the rotating rod 806, and the rotation of the ratchet 807 is more stable.

[0034] In this embodiment, a linkage structure 9 is provided between the two connection structures 8. The linkage structure 9 includes a linkage rod 1 901. The linkage rod 1 901 is fixedly installed on the top of the two movable rods 802. A linkage rod 2 902 is fixedly installed between the two limit rods 811.

[0035] The linkage structure 9 allows the limiting rod 811 to rotate at the same time, thereby releasing the limiting of the ratchet wheel 807 at the same time, and the movable rod 802 can also move at the same time, which is more convenient and quick.

[0036] In this embodiment, the first connecting rod 901 does not contact the connecting tube 5 , and the second connecting rod 902 is located inside the connecting seat 804 and does not contact the connecting tube 5 .

[0037] The connecting pipe 5 will not affect the displacement of the connecting rod 1 901 and the rotation of the connecting rod 2 902, and is more stable and convenient.

[0038] It should be noted that the utility model is a pipeline installation structure of a gas detector. When in use, the installation groove 6 provided on the bottom connecting pipe 5 of the gas detector body 4 is aligned with the branch pipe 2 provided on the pipeline 1 for installation, and the sealing ring 7 makes the connection between the gas detector body 4 and the branch pipe 2 more sealed;

[0039] After alignment, the adjusting rod 812 is pulled to drive the limiting rod 811 to rotate upward along the rotating rod 810, and the other limiting rod 811 is driven to move synchronously through the connecting rod 902, so that the limiting effect of the limiting rod 811 on the ratchet 807 is synchronously released, and the movable rod 802 is driven to move downward along the sliding groove 805 provided in the connecting seat 804 by pulling the connecting rod 1 901, so that the clamping seat 803 is lower than the connecting ring 801, and then the adjusting rod 812 is released, and the spring 808 between the mounting rod 808 and the limiting rod 811 is released. Under the elastic force of 09, the limit rod 811 returns to its original position and limits the ratchet 807. By pulling the linkage rod 901, the holder 803 moves upward, so that it can tightly abut against the bottom end of the connecting ring 801, so that the gas detector body 4 can be tightly installed on the branch pipe 2. After the installation is completed, due to the applicability matching of the adjustment slot 813 and the ratchet 807, the limit rod 811 prevents the ratchet 807 from rotating along the rotating rod 806, playing a limiting role, so that the movable rod 802 will not move downward;

[0040] By opening the valve 3, the gas detector body 4 can detect the gas in the pipeline 1. After the detection is completed, the valve 3 is closed, and the limit is released by pulling the adjustment rod 812, so that the movable rod 802 can drive the holder 803 to move downward, so that the gas detector body 4 can be removed.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
