Description

Technical Field

[0001] The utility model relates to the technical field of laboratory bench equipment, and more specifically, to a multifunctional aluminum-plastic laboratory bench. Background Art

[0002] A laboratory bench is a table used by enterprises and institutions such as hospitals, schools, chemical plants, and research institutes for experimental testing and instrument storage. According to the placement position, it can be divided into: central laboratory bench, side laboratory bench, and corner bench; according to the material, it can be divided into: all-steel laboratory bench, steel-wood laboratory bench, all-wood laboratory bench, PP laboratory bench, aluminum-plastic laboratory bench, etc.

[0003] The existing multifunctional aluminum-plastic laboratory bench, such as "A Multifunctional Test Bench with Aluminum-Wood Frame" proposed in the application number 202121838648.8, includes a tabletop device, an anti-theft device, a placement device, auxiliary equipment, and a cleaning device. The lower surface of the support plate is connected to the upper surface of the laboratory bench. The lower surfaces of the two sliding grooves are both connected to the upper surface of the laboratory bench. The two sliders are respectively slidably matched with the two sliding grooves. One side surfaces of the two fixing plates are respectively connected to one side surfaces of the two sliders. The other side surfaces of the two fixing plates are both connected to the outer surface of the placement groove. One side surface of the record book groove is connected to one side surface of the laboratory bench. In the multifunctional test bench with aluminum-wood frame of the utility model, the items needed in the experiment are placed in the placement groove and on the hooks. The hooks can slide on the cross bar. The sliders are slidably matched with the sliding grooves to drive the fixing plates to move, and then the placement groove and the hooks can be driven to move. The experimenter can move to a suitable position according to the needs, which is convenient for taking experimental items during the experiment.

[0004] After the existing multifunctional aluminum-plastic laboratory bench finishes the experimental operation, the tabletop is easily soiled. Generally, a brush barrel is used in cooperation with a cleaning agent to brush and clean the tabletop. Although it can quickly clean the tabletop of the laboratory bench, in the actual use process, most of the sewage on the laboratory bench can flow out from the sewage outlet provided on the laboratory bench, but part of the water flow is easily directly dropped from the laboratory bench surface, which is likely to pollute the ground or stain the operator's clothes. Moreover, there is no filtering mechanism at the sewage outlet, which is likely to cause the sewage outlet to be blocked and requires frequent cleaning, which is time-consuming and affects the use effect. Therefore, it is urgent to improve the technology of the structure of the multifunctional aluminum-plastic laboratory bench to improve this equipment. Summary of the Utility Model

A rotating shaft 11 penetrates through the inside of the brush barrel 10, and the frame 2 and the fixed plate 9 drive the brush barrel 10 to rotate itself and move back and forth horizontally through a transmission mechanism;

[0031] A sprinkler head 18 is installed on the right side wall of the frame 2, the water pipe at the sprinkler head 18 is connected to a water tank, a sewage discharge groove 19 is opened at the top end of the test bench 1, a sewage discharge pipe 20 is communicated with the side end of the sewage discharge groove 19, the sewage discharge pipe 20 extends to the outside of the test bench 1, a filter screen rack 21 is installed inside the sewage discharge groove 19, and the test bench 1 and the filter screen rack 21 are installed with the filter screen rack 21 through a clamping mechanism.

[0032] By arranging a fixed plate 9 at the front end of the frame 2, when cleaning the tabletop of the experimental table 1, the tabletop of the experimental table 1 can be enclosed to prevent sewage from flowing out of the experimental table 1. And when cleaning the tabletop of the experimental table 1, the motor 17 works. Through the transmission mechanism, the brush barrel 10 rotates and moves horizontally at the same time, and cooperates with the cleaning agent sprayed by the nozzle 18 to brush and sweep the tabletop of the experimental table 1. Then the formed sewage can be filtered by the filter screen frame 21 and then flow out through the sewage discharge pipe 20 for collection. Larger dust impurities in the sewage can be blocked to prevent the sewage discharge pipe 20 from being blocked. And the filter screen frame 21 can be installed in the sewage discharge groove 19 by being limited by the clamping mechanism, and the filter screen frame 21 can be disassembled and cleaned more conveniently, which is convenient to use.

[0033] Please refer to Figures 2-5 , a gear 12 is fixedly connected to the front end of the rotating shaft 11, a rack 13 is fixed in the fixed plate 9, the gear 12 is located in the fixed plate 9 and meshes with the rack 13. The rear end of the rotating shaft 11 is rotatably connected to a slider 14. A chute 15 is opened at one end of the frame 2 corresponding to the slider 14. The slider 14 is slidably connected in the chute 15. A threaded rod 16 is threadedly connected in the slider 14. A part of the threaded rod 16 is located in the chute 15 and is rotatably connected to the chute 15.

The right end of the threaded rod 16 is fixedly connected to a motor 17, and the motor 17 is mounted on the side end of the frame 2.

[0034] Please refer to Figures 2-3 , the sizes of the slider 14 and the chute 15 match each other, and a polishing layer is provided at the contact part between the slider 14 and the chute 15. By providing a polishing layer at the contact part between the slider 14 and the chute 15, the friction between the slider 14 and the chute 15 is reduced, avoiding the relatively stuck movement of the slider 14 in the chute 15 and affecting the use effect. The sewage discharge pipe 20 is inclined, and the sewage discharge pipe 20 inclines downward from the sewage discharge groove 19 towards the outside of the experimental table 1. By setting the sewage discharge pipe 20 to incline downward from the sewage discharge groove 19 towards the outside of the experimental table 1, the sewage can smoothly flow out through the sewage discharge pipe 20 due to gravity.

[0035] Please refer to Figure 2 and Figure 4 , spring grooves 22 are opened at the left and right side walls of the experimental table 1 close to the sewage discharge groove 19.

[0036] Working principle: When this multifunctional aluminum-plastic experimental table is in use, first, move the filter screen rack 21 into the sewage discharge tank 19. The filter screen rack 21 abuts against the convex block 24, causing the convex block 24 to gradually move into the inside of the spring groove 22. When the convex block 24 is aligned with the groove 25, the convex block 24 is elastically snapped into the groove 25 by the restoring elastic force formed with the spring 23, thereby clamping and installing the filter screen rack 21. After that, experiments can be carried out by operating on the experimental table 1. The table cabinets 3 and drawers 4 on the experimental table 1 can store instruments with larger sizes or relatively valuable items. The placement rack 5 on the experimental table 1 can temporarily place the required experimental equipment, and the hooks 8 on the experimental table 1 can hang some experimental items to achieve the purpose of being taken and used at any time;

[0037] When it is necessary to clean the tabletop of the experimental table 1 after the operation is completed, the motor 17 works. Through the transmission mechanism, the brush barrel 10 rotates and moves horizontally at the same time, and cooperates with the cleaning agent sprayed by the nozzle 18 to brush and sweep the tabletop of the experimental table 1. This operation method increases the friction force with the tabletop of the experimental table 1 and improves the brushing effect. Then, the formed sewage can be filtered by the filter screen rack 21 and then flow out through the sewage discharge pipe 20 for collection. Larger dust impurities in the sewage can be blocked to prevent the sewage discharge pipe 20 from being blocked, which is convenient for use.

[0038] 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.
