[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Example 1, as Figure 1-4 As shown, the utility model provides a technical solution: an active optoelectronic protection device fixing device for environmental testing, comprising a base 1, a fixing mechanism 1 and a fixing mechanism 2, wherein the fixing mechanism 1 and the fixing mechanism 2 are symmetrically arranged about the vertical center line of the base 1, the fixing mechanism 1 comprises two parallel fixed columns 1 3 and a movable column 1 2, the fixing mechanism 2 comprises two parallel fixed columns 2 12 and a movable column 2 11, the bottoms of the movable columns 1 2 and the movable columns 2 11 are fixedly provided with a slide 6, and the bottom surface of the base 1 is fixedly provided with a slide for accommodating the slide 6. A movable slide rail seat 4 is provided, one end of the slide of the movable column 1 2 is fixed with a gear row 1 7 by bolts, one end of the slide of the movable column 2 11 is fixed with a gear row 2 10 by bolts, and a shell 8 is fixed with bolts at the bottom of the base 1. The shell 8 is provided with a through groove for accommodating the gear row 1 7 and the gear row 2 10 to slide through. A gear 13 is provided inside the shell 8 to rotate through the rotating shaft. The gear 13 is respectively engaged with the gear row 1 7 and the gear row 2 10. The gear row 1 7 is located directly below the gear row 2 10, and the tooth body of the gear row 1 7 faces the gear row 2 10, and the tooth body of the gear row 2 10 faces the gear row 1 7.
[0021] In a specific embodiment of the present invention, four supporting feet 5 are provided at the bottom of the base 1, and a rubber pad or a suction cup base is provided at the bottom of each supporting foot 5 to improve the overall stability of the base 1. The slide 6 is pre-inserted and slidably arranged inside the slide rail seat 4, and then the connection between the bottom of the movable column 2 and the slide 6 is fastened with bolts. A pad 601 needs to be added between the slide 6 at the bottom of the movable column 2 and the gear row 1 7 to ensure that the gear row 1 7 and the gear row 2 10 have a certain spacing space. A damping shaft structure is provided inside the shell 8, and the rotating shaft in the damping shaft structure is matched with the gear 13 through a key. At the same time, one end of the rotating shaft in the damping shaft structure is connected to the handle 9, so that the gear 13 is rotated by the handle 9, thereby realizing the relative movement of the gear row 1 7 and the gear row 2 10. The damping coefficient in the damping shaft structure is designed to be 2, and the damping coefficient is designed to be large, so that the movable column has a certain stability, which is convenient for stably clamping the sample.
[0022] In the preferred technical solution, the rotating shaft connected to the gear 13 inside the shell 8 is a damping rotating shaft, and a handle 9 for rotating the gear 13 is provided at one end of the damping rotating shaft. By rotating the gear 13 using the handle 9, the relative movement of the gear row 1 7 and the gear row 2 10 can be achieved. The rotating shaft is set as a damping rotating shaft, so that the movable column has a certain stability after adjustment, thereby facilitating stable clamping of the sample.
[0023] In the preferred technical solution, a pad 601 is provided between the slide seat of the movable column 2 and the gear row 7, and the gear row 7 is fixed to the bottom of the pad 601 by bolts. The pad 601 needs to be added between the slide seat 6 at the bottom of the movable column 2 and the gear row 7 to ensure that there is a certain spacing between the gear row 7 and the gear row 2 10, so as to meet the requirement that the gear row 7 and the gear row 2 1 are engaged with the gear 13 at the same time.
[0024] In the preferred technical solution, a limiting groove 101 is provided on the surface of the base 1 to accommodate the lateral sliding of the movable column 1 2 . The limiting groove 101 is used to limit the direction of movement of the movable column, thereby improving the stability of the movable column.
[0025] In the preferred technical solution, a rubber layer is provided on the surfaces of the fixed column 1 3 , the movable column 1 2 , the fixed column 2 12 and the movable column 2 11 . The rubber layer increases the friction force of the column clamping the sample surface and improves the clamping stability.
[0026] Working principle: by placing a set of two samples front and back on the fixed mechanism one, that is, between the movable column one 2 and the fixed column one 3, the samples are close to the fixed column one 3, and then another set of samples are placed front and back on the fixed mechanism two, that is, between the fixed column two 12 and the movable column two 11, and the samples are close to the fixed column two 12. By rotating the handle 9 set on the outside of the two front and rear shells 8 at the bottom of the base 1, the position of the movable column two 11 and the movable column one 2 can be adjusted synchronously, so that the movable column cooperates with the fixed column to clamp the sample. Since the gear 13 is set on the damping shaft and the damping coefficient of the damping shaft is designed to be large, the movable column has a certain stability, which is convenient for stably clamping the sample. Since the column is set at a height, the samples can be stacked, and multiple groups of samples can be tested at one time, thereby improving the experimental efficiency.
