[0002] There are scattered light type, transmitted light type, transmitted and scattered light type, etc. for the turbidimeter method, which are collectively called optical turbidimeters. Its principle is that when light irradiates the liquid surface, there is a certain correlation between the ratios of the incident light intensity, transmitted light intensity, and scattered light intensity to each other and the turbidity of the water sample. The turbidity of the water sample is measured by measuring the ratio of the transmitted light intensity, scattered light intensity, and incident light intensity or the ratio of the transmitted light intensity to the scattered light intensity.

The fixing component 3 serves to facilitate fixing the display instrument placed on the surface of the placement shell 6. When the support structure needs to be folded, the first motor 21 is started by retracting the component 2. The output end of the first motor 21 drives the screw 29 to rotate. The rotation of the screw 29 drives the connecting block 27 to move in the vertical shell 1. The connecting block 27 moves up and down and drives the four connecting rods 28 to move synchronously. At the same time, the limiting groove 25 serves to facilitate limiting the moving position of the connecting rod 28. The four connecting rods 28 move synchronously and drive the connecting ring 26 to move. The movement of the connecting ring 26 drives the second hinge seat 201 to move.

The outer surface of the gear 34 is meshed with two toothed plates 39. One end of each of the two toothed plates 39 is fixedly connected to a vertical rod 37, and the bottom ends of the two vertical rods 37 are both slidably connected to the lower inner wall of the placement shell 6.

[0028] Both ends of the four connecting rods 28 are respectively slidably connected to the inner walls on both sides of the four limiting grooves 25, and the four connecting rods 28 are distributed in a circular array. The cooperation of the limiting grooves 25 and the connecting rods 28 plays a role in facilitating the position limitation of the movement of the connecting rods 28 in the vertical direction. The circular array distribution of the connecting rods 28 facilitates the four connecting rods 28 to jointly drive the connecting ring 26 to move.
[0029] Both bottom ends of the two toothed plates 39 are fixedly connected to long plates 33. Two long grooves 32 for cooperating with the long plates 33 are opened on the lower inner wall of the placement shell 6.

[0031] The tooth shapes of the two toothed plates 39 are the same as those of the gear 34, and the heights of the two toothed plates 39 are flush with each other, which facilitates the rotation of the gear 34 to drive the two toothed plates 39 to move synchronously.
[0032] Working principle: First, the four legs 5 are supported and placed at appropriate positions for use through the contraction assembly 2, and then the display instrument to be fixed is placed on the placing shell 6;
[0033] Then, through the fixing assembly 3, the second motor 35 is started. The output end of the second motor 35 drives the round rod 301 to rotate. The rotation of the round rod 301 drives the gear 34 to rotate. The rotation of the gear 34 drives the two toothed plates 39 to move synchronously in opposite directions. At the same time, the long groove 32 and the long plate 33 are used in cooperation to play a role in supporting and guiding the movement of the two toothed plates 39;
[0034] The movement of the toothed plate 39 drives the two vertical rods 37 to move. At the same time, the guide groove 302 plays a role in guiding the movement of the vertical rod 37. The two vertical rods 37 drive the two fixing plates 38 to move towards the opposite surfaces to fix the display instrument on the placing shell 6;
[0035] At the same time, the anti-slip pad 303 in the mounting groove 31 plays a role in anti-slip, making the fixing effect of the fixing plate 38 better;
[0036] When the bracket structure needs to be folded and stored, the display instrument is removed;
[0037] Then, through the contraction assembly 2, the first motor 21 is started. The output end of the first motor 21 drives the screw rod 29 to rotate. The rotation of the screw rod 29 drives the connection block 27 to move in the vertical shell 1. The up and down movement of the connection block 27 drives the four connecting rods 28 to move synchronously. At the same time, the limiting groove 25 plays a role in limiting the moving position of the connecting rod 28;
[0038] The four connecting rods 28 move synchronously to drive the connecting ring 26 to move together. At the same time, the vertical shell 1 plays a role in guiding the movement of the connecting ring 26. The movement of the connecting ring 26 drives the second hinge seat 201 to move;
[0039] When the four second hinge seats 201 move upward, they cooperate with the long rod 24 and the connecting piece 23 to make the four legs 5 contract towards the middle, so as to achieve the purpose of folding the bracket structure.
