[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a chemical test tube fixing rack, including a fixed frame body 1, a plurality of fixed seats 2 are slidably arranged on the fixed frame body 1, the fixed seat 2 includes a fixed clamping seat 21 and a movable clamping seat 22, arc grooves 24 are respectively arranged on the inner sides of the fixed clamping seat 21 and the movable clamping seat 22, the fixed clamping seat 21 and the movable clamping seat 22 are elastically connected by a spring 23, a test tube body 3 is placed between the fixed clamping seat 21 and the movable clamping seat 22, a slide block 26 is arranged on the fixed clamping seat 21, the fixed frame body 1 includes a vertical plate 12, a plurality of damping slide rails 13 are arranged on the vertical plate 12, and the slide block 26 is slidably connected with the damping slide rail 13.

[0026] A fixing groove is formed between the arc groove 24 of the fixed clamping seat 21 and the arc groove 24 of the movable clamping seat 22 for fixing the test tube body 3. Apply a certain external force to the movable clamping seat 22, and a plurality of springs 23 are stretched. At this time, the movable clamping seat 22 moves away from the fixed clamping seat 21, and the distance between the arc grooves 24 of the fixed clamping seat 21 and the movable clamping seat 22 becomes larger. Insert the test tube body 3 to be fixed into the fixing groove. After insertion, release the external force applied to the movable clamping seat 22, and a plurality of springs 23 drive the movable clamping seat 22 to rebound by their own elastic force, and the inner sides of the movable clamping seat 22 and the fixed clamping seat 21 are closely attached to the surface of the test tube body 3, realizing the fixation of the test tube body 3.

[0027] During actual use, the position of the movable clamping seat 22 can be adaptively adjusted according to the diameter size of the test tube body 3, so that the overall test tube fixing rack is applicable to test tube bodies 3 of different specifications, and has high use flexibility.

[0028] The fixed seat 2 is slidably arranged on the damping slide rail 13, and there is a certain damping force between the two. When it is necessary to slide the fixed seat 2, apply sufficient external force to overcome the damping force, and the fixed seat 2 can be axially driven to flexibly adjust the height position of the fixed seat 2. When the external force is released, the fixed seat 2 is stabilized by relying on the damping force.

[0029] During actual use, the height of the corresponding fixing seat 2 can be adjusted according to the length of the test tube body 3, improving the fixing effect.

[0030] Wherein, a fixing groove is formed between the arc-shaped grooves 24 of the fixed clamping seat 21 and the arc-shaped grooves 24 of the movable clamping seat 22, and an elastic anti-slip inner lining 25 is adhesively fixed on the inner side surface of the arc-shaped groove 24.

[0031] After the test tube body 3 is fixed, the elastic anti-slip inner lining 25 on the inner side surface of the fixed clamping seat 21 is in close contact with one side surface of the test tube body 3, and the elastic anti-slip inner lining 25 on the inner side surface of the movable clamping seat 22 is in close contact with the other side surface of the test tube body 3, improving the contact friction force. At the same time, the elastic anti-slip inner lining 25 has a certain elastic force effect, and is in elastic contact with the test tube body 3 to prevent damage to the test tube body 3.

[0032] Wherein, multiple groups of springs 23 are distributed on both sides of the fixed clamping seat 21 and the movable clamping seat 22, and one end of the spring 23 is fixed to the fixed clamping seat 21, and the other end of the spring 23 is fixed to the movable clamping seat 22. The fixed clamping seat 21 and the movable clamping seat 22 are elastically connected by multiple groups of springs 23, and the position of the movable clamping seat 22 relative to the fixed clamping seat 21 is adjustable. By adjusting the position of the movable clamping seat 22, the shape of the fixing groove is correspondingly adjusted, and the fixing groove can clamp and fix various test tube bodies 3.

[0033] Wherein, the damping slide rail 13 includes a damping chute 14, and the slider 26 of the fixed clamping seat 21 is embedded in the damping chute 14. There is a certain damping force between the slider 26 and the damping chute 14, that is, there is a certain damping force between the fixed clamping seat 21 and the damping slide rail 13, and the fixing seat 2 relies on this damping force to remain stable on the damping slide rail 13.

[0034] Wherein, the fixing frame body 1 includes a bottom plate 11. When fixing the test tube body 3, the bottom of the test tube body 3 can be in contact with the bottom plate 11.

[0035] Wherein, anti-slip foot pads 16 are fixedly arranged on both sides of the lower end surface of the bottom plate 11, and the anti-slip foot pads 16 play a role in anti-slip, so that the overall fixing frame can be stably placed on the table.

[0036] Wherein, the bottom plate 11 and the vertical plate 12 are vertically arranged.

[0037] Wherein, multiple groups of through grooves 15 are formed on the vertical plate 12. The setting of the multiple groups of through grooves 15 reduces the self-weight and material usage of the overall fixing frame, reducing the production cost.

[0038] Wherein, multiple groups of fixing seats 2 are arranged in one-to-one correspondence with multiple groups of damping slide rails 13, and the fixing seat 2 and the damping slide rail 13 are detachably connected. When the fixing seat 2 at a certain position is damaged, the fixing seat 2 can be replaced separately.

[0039] Working principle: Adjust the position of the fixed seat 2 according to the usage requirements, apply sufficient external force to overcome the damping force between the fixed seat 2 and the damping slide rail 13, axially drive the fixed seat 2, and flexibly adjust the height position of the fixed seat 2. The fixed seat 2 is stabilized by the damping force. Apply a certain external force to the movable clamping seat 22, and multiple springs 23 are stretched. At this time, the movable clamping seat 22 moves away from the fixed clamping seat 21, and the distance between the arc-shaped grooves 24 of the fixed clamping seat 21 and the movable clamping seat 22 becomes larger. Insert the test tube body 3 to be fixed into the fixing groove. After insertion, remove the external force applied to the movable clamping seat 22. Multiple springs 23 drive the movable clamping seat 22 to rebound by their own elastic force. The inner sides of the movable clamping seat 22 and the fixed clamping seat 21 are closely attached to the surface of the test tube body 3, realizing the fixation of the test tube body 3. The position of the movable clamping seat 22 can be adaptively adjusted according to the diameter of the test tube body 3. The overall test tube fixing rack is applicable to test tube bodies 3 of different specifications, realizing the fixation of multiple test tubes.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
