The utility model has a simple structure and an ingenious design. The up and down movement of the gas detector body 3 is achieved by adopting a scissor-fork structure, which occupies a small space, is easy to store, can meet actual needs, and is suitable for promotion. When the utility model is used, when the scissors-fork structure is in a retracted state, the scissors-fork structure is completely retracted into the box body 1, and the upper side of the bottom plate 2 is tightly against the box body 1, occupying a small space. At this time, the gas detector body 3 is in a high place, which is convenient for detecting gas; when the scissors-fork structure is in a retracted state, the lower end of the scissors-fork structure extends downward, driving the bottom plate 2 and the gas detector body 3 to move downward, which is convenient for repairing the gas detector body 3; the scissors-fork structure has good self-locking ability during extension or contraction, and can remain relatively stable even under load conditions, and is not prone to accidental collapse.

[0018] Specifically, as shown in the figure, the scissor-fork structure described in this embodiment includes several components, and six components are provided in this embodiment. The components include two hinged connecting rods 4, the middle parts of the two connecting rods 4 cross and hingedly connect to form a component, and the corresponding ends of the connecting rods 4 of two adjacent groups of components are hingedly connected to form a plurality of X-shaped superimposed forms. When the end of the connecting rod 4 in the uppermost component is driven to move inward or outward, the relative angles between the several connecting rods 4 change through the transmission of the hinge point, so that the end of the connecting rod 4 in the lowermost component moves downward or upward, thereby realizing the length change in the vertical direction of the scissor-fork structure.

[0019] Further, as shown in the figure, the driving device described in this embodiment includes a screw rod 20, which is rotatably mounted on the box body 1 through a bearing, and the two ends of the screw rod 20 are rotatably mounted on the side wall of the box body 1 through bearings, one end of the screw rod 20 extends out of the outside of the box body 1, and the threads of the two ends of the screw rod 20 are opposite in rotation direction. The two ends of the screw rod 20 are respectively threaded to fit with a nut 21, and the nut 21 can only move linearly along the screw rod 20, and the upper end of the nut 21 is respectively fixed with a slide rod 30, and a corresponding slide groove 31 is provided on the inner wall of the box body 1, and the slide rod 30 is respectively slidably mounted in the slide groove 31, and the inner wall of the slide groove 31 is respectively in sliding contact with the outer wall corresponding to the slide rod 30, and the nut 21 is respectively hinged and rotated to connect the upper ends of the two connecting rods 4 on the upper side of the scissor-fork structure. The screw rod 20 rotates, driving the two nuts 21 to move relative to or away from each other along the screw rod 20, thereby driving the end of the connecting rod 4 in the uppermost member to move inward or outward, so as to realize the telescopic structure of the scissor-fork structure.

[0020] Furthermore, as shown in the figure, the first roller 40 is fixedly installed at one end of the screw rod 20 in this embodiment, and a number of evenly distributed slots 41 are provided on the outer periphery of the first roller 40. A dense bead pull rope 42 is installed on the outer periphery of the first roller 40. The small beads of the dense bead pull rope 42 can be engaged with the corresponding slots 41. The dense bead pull rope 42 is an annular pull rope with small beads densely arranged on the surface. The front and rear sides of the first roller 40 are rotatably provided with second rollers 43, and the second roller 43 can contact and cooperate with the dense bead pull rope 42. By pulling the dense bead pull rope 42, the small beads on the dense bead pull rope 42 give thrust to the side wall of the corresponding slot 41, thereby driving the first roller 40 to rotate, and the rotation of the first roller 40 drives the screw rod 20 to rotate, and the two second rollers 43 can ensure that there are always small beads engaged and installed in the slot 41.

[0021] Furthermore, as shown in the figure, a plurality of mounting plates 50 are fixedly mounted on the side wall of the box body 1 in this embodiment, and a mounting plate 50 is fixedly mounted on the upper, left and right sides of the box body 1, respectively.

[0022] Furthermore, as shown in the figure, the vertical plate 60 is fixedly mounted on the bottom plate 2 of the present embodiment, and the gas detector body 3 is fixedly mounted on the upper part of the vertical plate 60. The back of the vertical plate 60 is in sliding contact with the corresponding side wall of the box body 1. The upper side of the bottom plate 2 is provided with a protrusion, and the side walls of the protrusion can respectively contact and cooperate with the corresponding inner wall of the box body 1. The vertical plate 60 can increase the stability of the bottom plate 2 when it moves up and down, and the protrusion on the upper side of the bottom plate 2 can seal the bottom plate 2 and the box body 1 when entering the box body 1, preventing dust from entering the box body 1.

[0023] Furthermore, as shown in the figure, the ends of the lowermost connecting rod 4 of this embodiment are respectively hinged and rotatably installed with dovetail sliders 70, and a dovetail slot 71 is provided on the bottom plate 2. The dovetail slider 70 is slidably installed in the dovetail slot 71, and the inner wall of the dovetail slot 71 is respectively in sliding contact with the corresponding side wall of the dovetail slider 70. The cooperation between the dovetail slider 70 and the dovetail slot 71 enables the lower end of the lowermost connecting rod 4 to move freely in the horizontal direction when the vertical length of the scissor structure changes, and at the same time, it can prevent the dovetail slider 70 from being separated from the bottom plate 2.
