Then, by the elastic action of the compression spring 36, the movable rod 35 is pushed downwards, and the bottom of the movable rod 35 stably penetrates into the inner cavity of the positioning hole 33 to limit and fix the fixed shaft 32 and the grip 2, ensuring the stable storage of the grip 2 and shielding and protecting the lens.

[0044] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0045] The embodiments of the present utility model disclose a gas optical remote telemetry device.

[0046] According to the appendix Figure 1As shown in Figures -5, it includes a gas telemeter 1, a grip 2, a storage mechanism 3, and a protection mechanism 4. The grip 2 is arranged below the gas telemeter 1. The gas telemeter 1 is held by the grip 2, which is convenient for using the gas telemeter 1 for detection. The gas telemeter 1 is a laser methane gas telemeter, which is used for remotely measuring the concentration of gas. The storage mechanism 3 is arranged between the gas telemeter 1 and the grip 2. The storage mechanism 3 is used to form a folding structure on the grip 2 and rotate and store the grip 2. The grip 2 is folded and stored by the storage mechanism 3, which is convenient for the storage and carrying of the gas telemeter 1. The protection mechanism 4 is arranged on the front of the gas telemeter 1. The protection mechanism 4 is used to form a shielding structure on the front of the gas telemeter 1 and protect the lens of the gas telemeter 1. The lens at the front of the gas telemeter 1 is protected by the protection mechanism 4 to prevent collision damage to the lens.

[0047] Specifically, the storage mechanism 3 includes a convex block 31, a fixed shaft 32, a positioning hole 33, a fixed tube 34, a movable rod 35, a compression spring 36 and a limit block 37. The top end of the convex block 31 is fixedly connected to the lower surface of the gas telemetry instrument 1. The convex block 31 is used to install the handle 2, connecting the top of the handle 2 to the lower surface of the gas telemetry instrument 1. One end of the fixed shaft 32 is rotatably inserted through one side of the outer wall of the convex block 31, and the other end of the fixed shaft 32 is fixedly inserted through one side of the top of the handle 2. The top of the handle 2 is rotatably connected to the lower surface of the gas telemetry instrument 1 through the fixed shaft 32 and the convex block 31, enabling the top of the handle 2 to rotate around the fixed shaft 32, facilitating the rotational folding of the handle 2. The positioning holes 33 are provided at the other end of the fixed shaft 32. The positioning holes 33 are arranged in a cross shape, and the two positioning holes 33 are perpendicular to each other, for installing the movable rod 35.

The compression spring 36 is arranged in the inner cavity of the fixed tube 34. The bottom end of the compression spring 36 is in contact with the top end of the movable rod 35. When the movable rod 35 slides upward into the inner cavity of the fixed tube 34, the compression spring 36 is compressed and deformed, and by using the elastic force of the compression spring 36, the movable rod 35 is pushed downward, ensuring that the bottom of the movable rod 35 is stably inserted into the inner cavity of the positioning hole 33. The limit block 37 is fixedly inserted through the bottom of the movable rod 35. The lower surface of the limit block 37 is in contact with the outer wall of one end of the fixed shaft 32. The limit block 37 is used to limit the bottom of the movable rod 35, and it is convenient to push the movable rod 35 upward through the limit block 37, enabling the movable rod 35 to disengage from the inner cavity of the positioning hole 33. A switch button is fixedly installed on the front of the convex block 31. The bottom of the convex block 31 is slidably inserted into the inner cavity of the handle 2. By rotating the handle 2 towards the front around the fixed shaft 32, the handle 2 rotates 90 degrees to the horizontal direction. Using the elastic force of the compression spring 36, the movable rod 35 is pushed downward, and the bottom of the movable rod 35 is stably inserted into the inner cavity of the positioning hole 33, limiting and fixing the fixed shaft 32 and the handle 2, ensuring the stable storage of the handle 2.

The fixing block 43 is rotatably inserted and connected to one end of the connecting shaft 42. The top of the cover plate 41 is rotatably connected to the bottom of the front of the gas telemeter 1 through the connecting shaft 42 and the fixing block 43, so that the cover plate 41 rotates around the connecting shaft 42 to open and close. The protrusion 44 is arranged on the front of the cover plate 41. By rotating the cover plate 41, the protrusion 44 is driven to rotate into the inner cavity of the front of the gas telemeter 1. The rubber pad 45 is fixedly connected to the front of the protrusion 44. The rubber pad 45 corresponds to the position of the lens of the gas telemeter 1. The rubber pad 45 is attached to the front of the lens of the gas telemeter 1 to protect the lens. The connecting rod 46 is arranged between the cover plate 41 and the handle 2. The connecting rod 46 is used to connect the cover plate 41 and the handle 2. The connecting block 47 is fixedly connected to one side of the back of the cover plate 41. The connecting block 47 is arranged in a long strip shape and is used to install one end of the connecting rod 46. The movable grooves are arranged on both sides of the connecting block 47. The mounting shaft 48 is fixedly inserted and connected to one end of the connecting rod 46. One end of one of the mounting shafts 48 is slidably inserted into the inner cavity of the movable groove. One end of the connecting rod 46 rotates and slides on the connecting block 47 through the mounting shaft 48. The fixing seat is fixedly connected to the bottom of the front of the handle 2. The fixing seat 49 is rotatably inserted and connected to one end of the mounting shaft 48. Both ends of the connecting rod 46 rotate around the mounting shaft 48. When the handle 2 is rotated towards the front, the connecting rod 46 is driven to move together. One end of the connecting rod 46 drives one of the mounting shafts 48 to slide in the inner cavity of the movable groove on the connecting block 47, and one end of the connecting rod 46 pushes the cover plate 41 towards the front, so that the cover plate 41 rotates upwards around the connecting shaft 42 to the front position of the gas telemeter 1 to shield and protect the lens.
