[0002] An ozone concentration measuring instrument is a device for measuring ozone concentration. It mainly uses the ultraviolet optical method for measurement. Since ozone has characteristic absorption of ultraviolet light at a specific wavelength, using this characteristic, the ozone concentration measuring instrument by ultraviolet optical method passes ultraviolet light of this wavelength and measures the degree of its absorption by ozone to calculate the ozone concentration.

[0003] The current ozone concentration measuring instrument mainly consists of an instrument main body and a U-shaped seat that can rotate on its outer wall. When the U-shape rotates upwards, it can be used as a handle for easy movement of the instrument main body. When the U-shape tilts downwards, it can support the instrument main body, so that the instrument main body can be placed obliquely upwards for the convenience of operation by the staff. However, there is no positioning between the rotating U-shaped seat and the instrument main body, resulting in the U-shaped seat being in a rotating state on the outer wall of the instrument main body all the time. Therefore, when the instrument main body moves, there will be a shaking phenomenon, and the U-shaped seat is not stable enough when supporting the instrument main body, thus reducing the stability of the use of the U-shaped seat.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0025] An embodiment of the utility model discloses an ultraviolet optical ozone concentration detector.

[0026] According to Figure 1 -3, it includes a detector main body 101. Turntables 103 are rotatably arranged on both sides of the detector main body 101. A U-shaped seat 102 is fixedly connected between the turntables 103. A rotating mechanism and a positioning mechanism are arranged between the turntable 103 and the detector main body 101. The turntable 103 rotates on both sides of the detector main body 101 through the rotating mechanism. Through the arrangement of the rotating mechanism, the U-shaped seat 102 can rotate, that is, the U-shaped seat 102 can be located Figure 1 In a state, so that the detector main body 101 can be moved through the U-shaped seat 102, and then the U-shaped seat 102 is rotated downward, which is okay. And the U-shaped seat 102 is in an inclined state, so that the inclined downward U-shaped seat 102 can support the detector main body 101, making the detector main body 101 inclined upward, which is convenient for the staff to operate the detector main body 101.

[0027] In a preferred embodiment, the positioning mechanism includes moving holes 201 symmetrically opened on one side of the turntable 103. A positioning rod 202 is movably inserted into the inner wall of the moving hole 201. A plurality of positioning holes 203 are annularly arranged on both sides of the detector main body 101. The outer wall of the positioning rod 202 is movably inserted into the inner wall of one of the positioning holes 203. A moving mechanism is arranged inside the turntable 103. When the U-shaped seat 102 rotates to the required angle through the turntable 103, the two positioning rods 202 are inserted out of the corresponding moving holes 201, and the positioning rods 202 are inserted into the corresponding positioning holes 203, so that the positioning holes 203 can limit the positioning rods 202. As long as the positioning rods 202 are not pulled out of the positioning holes 203, the turntable 103 cannot rotate anymore, so that the fixed-angle U-shaped seat 102 can be stably used, thus improving the stability of the U-shaped seat 102.

[0028] Among them, the rotating mechanism includes a rotating shaft 602 fixedly connected to one side of the turntable 103. Rotating holes 601 are opened on both sides of the detector main body 101. The outer wall of the rotating shaft 602 is rotatably connected to the inner wall of the rotating hole 601. By rotating the rotating shaft 602 in the rotating hole 601, the turntable 103 can rotate around the position of the rotating shaft 602, thus improving the convenience of the turntable 103 rotation.

[0029] Among them, the moving mechanism includes a movable cavity 301 opened inside the turntable 103. A gear 303 is rotatably connected inside the movable cavity 301. A second rack 305 is fixedly connected to the outer wall of the positioning rod 202. The outer wall of the gear 303 is meshed with the outer wall of the second rack 305. A limiting mechanism is arranged between the outer wall of the positioning rod 202 and the inner wall of the movable cavity 301. A moving block 302 is movably arranged on the inner wall of the movable cavity 301. A first rack 304 is fixedly connected to the outer wall of the moving block 302. The outer wall of the first rack 304 is connected to the outer wall of the gear 303. A pressing mechanism is arranged on the outer wall of the turntable 103. By moving the moving block 302 in the movable cavity 301, the gear 303 can be rotated under the meshing of the first rack 304 and the gear 303. When the gear 303 rotates, it can drive the second rack 305 to move, and the movement of the second rack 305 drives the positioning rod 202 to move, thereby improving the convenience of the movement of the positioning rod 202 and the operation of the positioning mechanism.

[0030] Among them, the pressing mechanism includes a pressing block 402. The pressing block 402 is fixedly connected to one side of the moving block 302. A communication hole 401 is opened on the side of the turntable 103 away from the rotating shaft 602. The outer wall of the pressing block 402 is movably inserted into the inner wall of the communication hole 401. A reset mechanism is arranged inside the movable cavity 301. Through the setting of the pressing block 402, the moving block 302 can be driven to move by pressing the pressing block 402 outside the turntable 103, thereby improving the convenience of the operation of the pressing mechanism.

[0031] Among them, the reset mechanism includes a counterbore 701 opened between the rotating shaft 602 and the turntable 103. A spring 702 is inserted into the counterbore 701. One side of the spring 702 is connected to the side of the moving block 302 away from the pressing block 402. Through the elastic action of the spring 702, the spring 702 always presses the moving block 302, so that the positioning rod 202 always has a tendency to move into the positioning hole 203. Therefore, as long as the pressing block 402 is not pressed, the positioning rod 202 can always be inserted into the positioning hole 203, thereby improving the stability of the operation of the positioning mechanism.

[0032] Among them, the limiting mechanism includes a fixed rod 502 fixedly connected to the inner wall of the movable cavity 301. A limiting hole 501 is opened at one end of the positioning rod 202. The outer wall of the fixed rod 502 is movably inserted into the inner wall of the limiting hole 501. An easy-insertion mechanism is arranged at the other end of the positioning rod 202. Through the mutual limitation of the fixed rod 502 and the limiting hole 501, the positioning rod 202 will not show a longitudinal offset phenomenon when moving, further improving the stability of the operation of the positioning mechanism.

[0033] Among them, the easy-insertion mechanism includes an easy-insertion block 503 fixedly connected to the other end of the positioning rod 202. The easy-insertion block 503 is frustum-shaped. The easy-insertion block 503 is inserted into the interior of the positioning hole 203. Through the frustum-shaped easy-insertion block 503, it is convenient for the positioning rod 202 to be inserted into the positioning hole 203, thereby improving the convenience of the operation of the positioning mechanism.

[0034] Among them, protective pads 801 are fixedly connected to the corners of the outer wall of the main body 101 of the measuring instrument. A protective block 802 is fixedly connected to the outer wall of the protective pad 801. A protective sleeve 901 is sleeved on the outer wall of the U-shaped seat 102. The corners of the main body 101 of the measuring instrument can be protected by the protective pads 801 and the protective block 802, making the main body 101 of the measuring instrument more drop-resistant. Through the arrangement of the protective sleeve 901, the U-shaped seat 102 is more stable when supporting the main body 101 of the measuring instrument.
