It can display the date, detection time, temperature and humidity data of the detection site.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology makes the formaldehyde detector an indoor detection instrument, so it needs to be connected with a matching bracket when in use. However, the existing bracket is generally connected to the formaldehyde detector by a plastic clip plug-in method. Because the plastic clip is tough, the toughness may deteriorate or the plastic may break after long-term use, which may cause the formaldehyde detector to separate from the bracket. Therefore, a detector for indoor formaldehyde detection is proposed to solve the above problem. Utility Model Content

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an indoor formaldehyde detector provided by an embodiment of the utility model comprises a detection device 1, two square frames 2 and a bracket 3, wherein the bottom of the detection device 1 is fixedly connected to the top of the square frame 2, and the bottom of the detection device 1 is movably connected to the top of the bracket 3;

[0025] A fixing component 4 for fixing the position of the bracket 3, wherein the fixing component 4 is arranged in the inner cavity of the square frame 2;

[0026] A connecting plate 5 is fixedly connected to the bottom of the detection device 1 , a docking groove 6 is provided on the rear side of the connecting plate 5 , and a transmission device 7 is provided at the bottom of the fixing component 4 .

[0028] The above scheme is adopted: by setting the docking plate 8 and the docking groove 6, when the bracket 3 is connected to the detection device 1, the docking plate 8 is inserted into the docking groove 6 on the rear side of the connecting plate 5, and the position of the bracket 3 can be positioned at this time, so that the insertion groove 9 will be aligned with the docking plate 8.

[0029] refer to Figure 3 The fixing assembly 4 includes a movable plate 41, a movable groove 42 is provided at the bottom of the movable plate 41, and a plug-in plate 43 used in conjunction with the plug-in slot 9 is fixedly connected to the opposite sides of the two movable plates 41. The plug-in plate 43 passes through the square frame 2 on the side close to the plug-in slot 9 and extends to the inner cavity of the plug-in slot 9. Springs 44 are provided on the front and rear sides of the opposite sides of the two movable plates 41.

[0030] By adopting the above scheme: by setting a fixing component 4, the plug-in plate 43 passes through the square frame 2 and the connecting plate 5 to the plug-in slot 9, the position of the docking plate 8 can be fixed, and the pressure of the squeezing rod 10 by the spring 44 can prevent the movable plate 41 from moving.

[0031] refer to Figure 4 The inner ring of the spring 44 is movably connected with an extrusion rod 10, and the side of the extrusion rod 10 close to the movable plate 41 is fixedly connected to the movable plate 41. The surface of the extrusion rod 10 is sleeved with a sleeve plate 11, and the side of the sleeve plate 11 close to the square frame 2 is fixedly connected to the inner wall of the square frame 2.

[0032] The above solution is adopted: by setting the extrusion rod 10 and the sleeve plate 11, when the extrusion rod 10 moves the extrusion spring 44, the sleeve plate 11 can control the moving position of the extrusion rod 10, so that the moving position of the movable plate 41 can be controlled when the extrusion rod 10 moves.

[0033] refer to Figure 3 The transmission device 7 includes a rotating plate 71, an extrusion hole 72 is opened at the bottom of the rotating plate 71, and a matching rod 73 is movably connected to the inner cavity of the extrusion hole 72. The matching rod 73 is fixedly connected to the movable plate 41 on the side close to the movable plate 41. The bottom of the rotating plate 71 is rotatably connected to a support plate 74 through a rotating shaft, and the support plate 74 is fixedly connected to the square frame 2 on the side close to the square frame 2.

[0034] By adopting the above solution: by setting the transmission device 7, when it is necessary to control the movement of the movable plate 41, the rotation of the rotating plate 71 will drive the inner wall of the extrusion hole 72 to squeeze the matching rod 73, and the matching rod 73 will be squeezed to drive the movable plate 41 to move in the square frame 2.

[0035] refer to Figure 3 The surface of the rotating plate 71 is fixedly connected with the first teeth 12, and the inner cavity of the square frame 2 is movably connected with the second teeth 13. The number of the first teeth 12 and the second teeth 13 is multiple and meshes with each other.

[0036] By adopting the above solution: by setting the first teeth 12 and the second teeth 13, when the two rotating plates 71 need to rotate, the movement of the control plate 14 will drive the multiple second teeth 13 to engage with the multiple first teeth 12, which will drive the rotating plate 71 to rotate.

[0037] refer to Figure 3 The inner cavity of the square frame 2 is movably connected to a control board 14, the second tooth 13 is fixedly connected to the control board 14 on one side close to the control board 14, the rear side of the control board 14 passes through the square frame 2 and extends to the outside of the square frame 2, and the top of the square frame 2 is fixedly connected to a pull rod 15.

[0038] By adopting the above solution: by setting the control plate 14 and the pull rod 15, when the two control plates 14 need to be moved simultaneously, the pull rod 15 can be pulled to drive the two control plates 14 to move in the square frame 2, so that the second teeth 13 can be engaged with the first teeth 12.

[0039] The working principle of this utility model:

[0040] When in use, when it is necessary to connect the detection device 1 with the bracket 3, hold the pull rod 15 and pull it. The movement of the pull rod 15 will drive the two control plates 14 to move. The movement of the control plate 14 will drive the multiple second teeth 13 to engage with the multiple first teeth 12. At this time, the rotating plate 71 will be driven to rotate. The rotation of the rotating plate 71 will drive the inner wall of the extrusion hole 72 to squeeze the matching rod 73. The matching rod 73 is squeezed and the movable plate 41 is moved in the square frame 2. The movement of the movable plate 41 will drive the extrusion rod 10 to squeeze the spring 44. When the movable plate 41 drives the plug-in plate 43 to move to the appropriate position, pick up the bracket 3 and drive the docking plate 8 to insert it into the docking groove 6 on the rear side of the connecting plate 5. Then the pull rod 15 can be released, and the spring 44 undergoes elastic deformation to drive the movable plate 41 back to its original position. The movement of the movable plate 41 will drive the plug-in plate 43 to penetrate the square frame 2 and the connecting plate 5 and extend to the inner cavity of the plug-in groove 9. At this time, the bracket 3 and the detection device 1 can be quickly connected and fixed.

[0041] To sum up: the detector for indoor formaldehyde detection is used in conjunction with the setting of a fixing component 4, a connecting plate 5, a docking slot 6 and a transmission device 7. The bracket 3 is picked up to drive the docking plate 8 to be inserted into the docking slot 6 on the rear side of the connecting plate 5, and then the pull rod 15 can be loosened. The spring 44 undergoes elastic deformation to drive the movable plate 41 back to its original position. The movement of the movable plate 41 will drive the plug-in plate 43 to penetrate the square frame 2 and the connecting plate 5 and extend to the inner cavity of the plug-in slot 9. At this time, the bracket 3 and the detection device 1 can be quickly connected and fixed, which solves the problem that the bracket 3 is generally connected to the formaldehyde detector by a plastic buckle plug-in method. Because the plastic buckle is tough, the toughness may deteriorate after long-term use or the plastic may break, which may cause the formaldehyde detector to separate from the bracket.
