Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides a gas detector that is convenient to install, including a base 1. The outer wall of the base 1 is fixedly connected with an adjusting seat 2. A rotating plate 3 is arranged on the adjusting seat 2. A curved hole is arranged on the rotating plate 3, and multiple groups of curved holes are provided. An installation structure 4 is arranged on the base 1. The installation structure 4 includes a pushing curved block 41. The inner wall of the base 1 is rotatably connected with the pushing curved block 41. The inner wall of the pushing curved block 41 is fixedly connected with a connecting shaft 42. One end of the connecting shaft 42 away from the pushing curved block 41 is fixedly connected with an adjusting disc 43. The outer wall of the adjusting disc 43 is fixedly connected with a push rod 44. A sliding seat 45 is slidably connected to the inner wall of the base 1. The inner wall of the sliding seat 45 is fixedly connected with clamping blocks 46. Two groups of clamping blocks 46 are provided. A curved surface is arranged on the clamping blocks 46 to facilitate contact with the inner wall of the installation hole. An arc-shaped groove is opened on the clamping blocks 46 to facilitate close contact with the outer wall of the pipeline.

[0029] In the present invention, a limit card slot 47 is opened on the adjusting disc 43. A first compression spring 5 is welded to the outer wall of the clamping block 46. A gas detector 6 is detachably connected to the inner wall of the rotating plate 3. A fixing plate 7 is fixedly connected to the outer wall of the rotating plate 3. Multiple groups of limit card slots 47 are provided. An installation card slot is opened on the gas detector 6. A sliding rod 8 is slidably connected to the inner wall of the fixing plate 7. One end of the sliding rod 8 is fixedly connected with a clamping block 9. The other end of the sliding rod 8 is fixedly connected with a movable plate 10. The fixing plate 7 and the movable plate 10 are elastically connected by a return spring 11. Two groups of sliding rods 8 are provided. The clamping block 9 can be clamped in the installation card slot on the gas detector 6. By moving the movable plate 10 to drive the sliding rod 8 to slide, the clamping block 9 is driven to move.

[0030] Further, a fixing block 12 is fixedly connected to the inner wall of the adjusting seat 2. A sliding rod 13 is fixedly connected to the inner wall of the fixing block 12. A limiting block 14 is fixedly connected to one end of the sliding rod 13. A synchronous plate 15 is fixedly connected to the other end of the sliding rod 13. A third compression spring is welded to the outer wall of the fixing block 12. The end of the third compression spring away from the fixing block 12 is welded to the outer wall of the synchronous plate 15. The limiting block 14 can be snapped into the limiting slot 47 on the adjusting disk 43, thereby completing the limiting work on the adjusting disk 43. Move the synchronous plate 15 to drive the sliding rod 13 to move, so that the limiting block 14 moves away from the adjusting disk 43, and the limiting state of the adjusting disk 43 is released. A receiving chute is provided on the adjusting seat 2. A sliding block 16 is slidably connected to the inner wall of the receiving chute. A second compression spring 17 is welded to the outer wall of the sliding block 16. The end of the second compression spring 17 away from the sliding block 16 is welded to the inner wall of the receiving chute. The receiving chute, the sliding block 16, and the second compression spring 17 are in a group, and there are three groups in total. By the second compression spring 17 squeezing the sliding block 16, it is convenient for the sliding block 16 to slide into the curved block on the rotating plate 3 in time. An activity groove 18 is opened on the adjusting seat 2. A shielding plate 19 is slidably connected to the inner wall of the activity groove 18. A convex platform is provided on the shielding plate 19. It is convenient to push the shielding plate 19 to slide on the inner wall of the activity groove 18 through the convex platform. The shielding work is carried out through the shielding plate 19 to reduce the entry of dust.

[0031] During use, by moving the synchronous plate 15, the sliding rod 13 is driven to move, so that the limiting block 14 moves away from the adjusting disk 43, and the limiting state of the adjusting disk 43 is released. By moving the push rod 44, the adjusting disk 43 is driven to rotate, and in cooperation with the connecting shaft 42, the pushing curved block 41 is driven to complete synchronous rotation. By the rotation of the pushing curved block 41, two sliding seats 45 can be pushed to slide on the inner wall of the base 1, so that the two clamping blocks 46 carry out clamping work. When the two clamping blocks 46 are separated, the inner wall of the wall mounting hole can be closely attached by the curved surfaces of the two clamping blocks 46 to complete the fixing work, or the two clamping blocks 46 are made to approach each other to clamp the pipeline by using the arc-shaped groove, improving the adaptability of the device. In cooperation with the first compression spring 5, the surfaces of the two clamping blocks 46 are ensured to be closely attached to the surface of the pushing curved block 41.

[0032] By moving the movable plate 10 upward, the clamping block 9 is driven to move, so that it is convenient to snap the gas detector 6 into the inner wall of the rotating plate 3. Release the movable plate 10, and the clamping block 9 is driven to reset by the return spring 11. At this time, when the clamping block 9 resets, it will also be snapped into the installation slot on the gas detector 6, quickly completing the connection work between the gas detector 6 and the rotating plate 3. By pushing the rotating plate 3, it is convenient to change the angle of the rotating plate 3. When the sliding block 16 slides into the curved block on the rotating plate 3, the angle fixing work of the rotating plate 3 is completed, and further the adjustment work of the placement position of the gas detector 6 is carried out, increasing the range where the device can be placed and facilitating adaptation to different on-site situations.
