Description

Technical Field

[0001] The utility model belongs to the technical field of pathological experiment, and specifically relates to a clean-air type pathological specimen-taking test bench. Background Technique

[0002] The clean-air type pathological specimen-taking table, also known as a clean-air type fume hood or a clean-air type workstation, is a new type of laboratory safety protection equipment. Its core principle is that the fan at the top of the equipment sucks in the harmful gases generated during the experiment and purifies them through a high-efficiency filter, thus preventing the direct emission of harmful gases into the room and ensuring the safety and health of experimental personnel. When conducting pathological examinations, diagnoses, and related scientific research, tissue samples need to be taken first. Since the samples taken are usually infiltrated and fixed with fixatives such as formaldehyde, toxic gases such as formaldehyde will be released and volatilized during the specimen-taking process. If not treated, their volatilization concentration far exceeds the national standard, causing harm to experimental personnel and the environment.

[0003] A kind of ion air curtain air supply and negative pressure exhaust clean-air type pathological specimen-taking table disclosed in the patent with application number 202321186168.7. It includes an upper cabinet, a lower cabinet is arranged at the lower part of the upper cabinet, stainless steel sandwich baffles are arranged on both sides of the upper cabinet, movable tempered glass baffles are arranged in the stainless steel sandwich baffles, and a fresh air ion flow air supply port, an LED lighting lamp, and an ultraviolet germicidal lamp are arranged at the top of the inner cavity of the upper cabinet.

[0004] At present, the above technical solution cannot adjust the level of the clean-air type pathological specimen-taking table, which may cause the clean-air type pathological specimen-taking table to be unable to maintain a stable state during long-term use. If the specimen-taking table is not installed horizontally, it may tilt during use, which will also greatly affect the accuracy of the experimental results and may pose a safety hazard to experimental personnel. Therefore, we provide a clean-air type pathological specimen-taking test bench to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a clean-air type pathological specimen-taking test bench, which specifically includes a base 1. The upper surface of the base 1 is fixedly connected with a test bench body 2. An electrical box 3 is installed on the outer surface of the test bench body 2. Four universal wheels 4 are fixedly connected to the bottom surface of the base 1. A horizontal adjustment mechanism 5 is arranged inside the base 1. Two groups of sealed doors 6 are installed on the outer surface of the test bench body 2. A connected water tank 7 is installed on the inner wall of the test bench body 2. A faucet 8 is fixedly connected to the outer surface of the test bench body 2. A drain pipe 9 is fixedly connected to the inner wall of the connected water tank 7. One end of the drain pipe 9 far away from the outer surface of the connected water tank 7 is fixedly connected with a valve 10. A display 11 is installed on the outer surface of the test bench body 2.

[0028] Please refer to Figure 3 and Figure 4 As shown in the figure, the horizontal adjustment mechanism 5 specifically includes a component cavity 501. The inner wall of the component cavity 501 is opened on the inner wall of the base 1. Two connecting grooves 502 are opened on the inner wall of the component cavity 501. A double-shaft motor 503 is fixedly connected to the inner wall of the component cavity 501. Two symmetrically arranged lead screws 504 are rotatably connected to the inner wall of the component cavity 501. One end of each of the two lead screws 504 close to each other is fixedly connected to the output end of the double-shaft motor 503. Two slide bars 505 are fixedly connected to the inner wall of the component cavity 501. The outer surfaces of the two lead screws 504 are both threadedly connected with moving plates 506. The inner wall of the moving plate 506 is slidably connected to the outer surface of the slide bar 505. In this embodiment, the movement of the moving plate 506 is limited by the slide bar 505. Thus, when the lead screw 504 rotates, the moving plate 506 cannot rotate along with it, enabling the moving plate 506 to move stably. One side surface of each of the two moving plates 506 away from each other is hinged with two hinge plates 507. One end of each of the two hinge plates 507 far away from the outer surface of the moving plate 506 is rotatably connected to a support plate 508. In this embodiment, when the two moving plates 506 move outward synchronously, at this time, the moving plate 506 can push the hinge plate 507 to move, and then while pushing, drive the hinged support plate 508 to move downward. Thus, the driven sleeve 509 and the support plate 512 move to lift the base 1 and the test bench body 2 as a whole, improving the overall stability of the equipment.

[0029] Please refer to Figure 3 and Figure 4As shown, four sleeves 509 are fixedly connected to the bottom surface of the support plate 508. The outer surfaces of the four sleeves 509 are rotatably connected to turning handles 511. The inner walls of the four sleeves 509 are slidably connected to threaded rods 510. The outer surfaces of the threaded rods 510 are threadedly connected to the inner walls of the turning handles 511. The bottom surfaces of the four threaded rods 510 are fixedly connected to support plates 512. In this embodiment, the material of the support plate 512 is preferably rubber. Thus, when the support plate 512 contacts the bottom surface for support, its material properties can increase the friction with the ground, enabling stable support. Two guide rods 513 are fixedly connected to the inner walls of the sleeves 509. Two symmetrically arranged chutes 514 are formed on the outer surfaces of the threaded rods 510. In this embodiment, the movement of the threaded rods 510 is limited by the combination of the guide rods 513 and the chutes 514. Thus, when the threaded rods 510 move, they drive the chutes 514 to slide on the surfaces of the guide rods 513, thereby preventing the threaded rods 510 from rotating with the turning handles 511 and causing failure of lifting adjustment. The outer surfaces of the two guide rods 513 are slidably connected to the inner walls of the chutes 514.

[0030] The specific working principle of the present utility model is as follows: First, the test bench body 2 and the base 1 can be displaced under the action of the universal wheels 4. After that, when the movement is completed, the double-shaft motor 503 is started to drive the lead screws 504 at both ends to rotate. Then, the rotation of the lead screws 504 drives the moving plates 506 on both sides to move outward synchronously. Then, the limiting effect of the slide rods 505 enables the moving plates 506 to slide stably. After that, the moving plates 506 can push the hinged plates 507 to drive the support plate 508 to move downward. At this time, the support plate 508 can drive the sleeves 509 and the support plates 512 to move downward to support the base 1. Finally, manually rotating the turning handle 511 can drive the threadedly connected threaded rod 510 to move up and down. At this time, the movement of the threaded rod 510 is limited by the combination of the guide rod 513 and the chute 514, enabling the threaded rod 510 to move up and down stably. Then, the threaded rod 510 can drive the support plate 512 to perform synchronous lifting adjustment, thereby enabling horizontal adjustment.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
