DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a gas detector with a multi-gas path structure, comprising a detector body 1 and a mounting assembly 2, a display light 11 is installed on one side of the detector body 1, the detector body 1 is installed and fixed by the mounting assembly 2, a multi-gas path assembly 12 is installed on the lower side of the detector body 1, the multi-gas path assembly 12 comprises an air inlet pipe 121, the air inlet pipe 121 is communicated with the detector body 1, a connecting pipe 122 is connected to the bottom end of the air inlet pipe 121, and a plurality of groups of branch pipes 123 are installed at the bottom end of the connecting pipe 122, a hose 124 is connected to the bottom end of the branch pipe 123, this structure enables gas detection to be carried out in a timely manner in multiple places at the same time, which greatly increases the safety of the device.

[0024] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the mounting assembly 2 includes a mounting seat 21, a connecting block 24 and a limiting assembly 3. The mounting seat 21 is fixed to the wall by bolts. A circular array of slots 22 and slide grooves 23 are provided on the surface of the mounting seat 21, and the slots 22 and the slide grooves 23 are connected. The connecting block 24 is fixedly connected to the detector body 1. An end of the connecting block 24 close to the mounting seat 21 is connected to an insert block 25, and the insert block 25 slides in the slide groove 23. The upper insert block 25 is fixed in the slide groove 23 by the limiting assembly 3. This structure makes The detector body 1 can be disassembled and assembled more conveniently, so that the subsequent maintenance and replacement of the detector body 1 is also more convenient. A positioning block 13 is connected to the end of the detector body 1 close to the mounting seat 21, and a positioning groove 26 is opened at the center position of the surface of the mounting seat 21. The positioning block 13 is inserted in the positioning groove 26. In order to make the plug 25 align with the slot 22 and insert it more accurately and quickly, the inner diameter of the slide groove 23 is adapted to the outer diameter of the plug 25, so that the plug 25 can slide more stably in the slide groove 23 and is not easy to shake.

[0025] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the limit assembly 3 includes a movable groove 31, a limit groove 34 and a driving assembly 4. The movable groove 31 is opened on the inner wall of the upper slide groove 23. A spring 32 is installed on the upper side of the movable groove 31. A limit rod 33 is slidably installed at the opening of the movable groove 31 through the driving assembly 4. The limit groove 34 is opened on the surface of the upper plug block 25. The limit rod 33 is inserted in the limit groove 34. This structure makes it possible to limit one group of plug blocks 25, so that the detector body 1 can be installed and fixed, making the detector body 1 more firmly installed. The outer diameter of the end of the limit rod 33 is adapted to the inner diameter of the limit groove 34, so that the detector body 1 is installed more firmly and not easy to shake.

[0026] As an implementation method in this embodiment, Figure 5 and Figure 6 As shown, the driving assembly 4 includes a mounting groove 41, which is opened on one side of the movable groove 31. A gear 42 is rotatably installed in the mounting groove 41, and a rack 1 43 and a rack 2 44 are respectively meshed on both sides of the gear 42. The rack 1 43 is connected to the limiting rod 33, and the top of the rack 2 44 is connected to a connecting rod 45. This structure makes it easier to drive the limiting rod 33 to slide, thereby making it easier to disassemble the detector body 1. A pressing block 46 is connected to the top of the connecting rod 45, and the outer diameter of the pressing block 46 is larger than the outer diameter of the connecting rod 45. In order to increase the area of ​​contact of the finger, it is more comfortable to drive the connecting rod 45 by pressing the pressing block 46.

[0027] Working principle: If the detector body 1 needs to be installed, it is only necessary to fix the mounting base 21 to the wall by bolts in advance, and then align the positioning block 13 with the positioning slot 26 and insert it, and at the same time rotate the detector body 1, the detector body 1 drives the connecting block 24 to rotate, and the connecting block 24 drives the inserting block 25, so that the inserting block 25 is aligned with the sliding slot 23 and inserted, and then the detector body 1 is rotated again, so that the inserting block 25 rotates and slides in the rotating sliding slot 23 from the slot 22, until the inserting block 25 is rotated to the side of the sliding slot 23 away from the slot 22, at this time, the upper side inserting block 25 will push and squeeze the limiting rod 33, and push the limiting rod 33 to compress the spring 32 in the movable slot 31, and when the limiting rod 33 corresponds to the limiting slot 34, the limiting rod 33 will be pushed by the restoring force of the spring 32 to be inserted into the limiting slot 34 to limit the inserting block 25, so that the installation of the detector body 1 can be completed, which greatly increases the practicality of the device;

[0028] At the same time, if gas detection is required at multiple locations, it is only necessary to stretch the hose 124, fix the opening of the hose 124 close to the location where gas needs to be detected, and then sequentially install the openings of multiple groups of hoses 124 corresponding to the locations where gas needs to be detected. In this way, the gas can enter the branch pipe 123 through the hose 124, then enter the air inlet pipe 121 through the connecting pipe 122, and finally enter the detector body 1 for detection. In this way, multiple locations can be detected simultaneously in a more timely manner, which better reduces the possibility of danger.

[0029] In addition, if the detector body 1 needs to be disassembled, it is only necessary to press the pressing block 46, and the pressing block 46 drives the connecting rod 45, and the connecting rod 45 drives the rack 2 44 to move downward in the installation groove 41. Through meshing, the rack 2 44 drives the gear 42 to rotate, and the gear 42 drives the rack 1 43 to move upward. At the same time, the rack 1 43 drives the limiting rod 33 to move upward until the limiting rod 33 is pulled out of the limiting groove 34 and moved into the movable groove 31. The detector body 1 can be rotated in the opposite direction, and the plug block 25 can be driven to slide in the slide groove 23 through the connecting block 24, so that the plug block 25 rotates into the slot 22. At this time, the detector body 1 also drives the positioning block 13 to rotate in the positioning groove 26. At this time, the detector body 1 can be pulled, so that the detector body 1 drives the positioning block 13 to be pulled out of the positioning groove 26, and at the same time drives the plug block 25 to be pulled out of the slot 22. In this way, the disassembly can be completed, which greatly increases the convenience of the device.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
