Problems solved by technology

The patent uses two motors to adjust the heights of the desks and chairs and the experimental bench respectively. On the one hand, the motor is heavy and inconvenient to move and carry the experimental desks and chairs; in addition, although the control of the motor and other mechanisms saves labor, if the students do not control it properly, it is easy to cause experimental accidents , it is not safe to use

Embodiment 1

[0042] Such as Figure 1~5 As shown, the combined physics experiment desk and chair includes a base 10 , a support plate 20 , a mounting plate 40 and an experiment table top 50 . The base 10 is arranged horizontally; in this embodiment, there are two support plates 20, which are symmetrically installed on the base 10 along the vertical direction. Mounting plate 40 is arranged on the top of support plate 20, specifically, mounting plate 40 can be directly installed on the support plate 20, also can be installed on the support plate 20 through other links; Experiment table top 50 is arranged on the top of mounting plate 40, Specifically, the test table 50 can be installed directly on the support plate 20 , or can be installed on the support plate 20 through other links.

[0043] The middle position of the upper surface of the base 10 is provided with a symmetrical fixed seat 81, and the fixed seat 81 is provided with a first screw rod 82 in the horizontal direction. The screw ...

Embodiment 2

[0047] This embodiment is further improved on the basis of embodiment 1, specifically, as Figure 1~2 As shown, the combined table and chair also includes a fixed plate 30 and a lifting device, the fixed plate 30 is arranged along the horizontal direction, and both ends of the fixed plate 30 are fixed on the supporting plate 20 .

[0048] The lifting device includes a first worm 61, a second worm 62, a third worm 63, a first worm 64 and a second worm 65; the two ends of the first worm 61 are rotatably mounted on the support plate 20, and the first worm 61 is connected to the base 10 are arranged in parallel; the first worm wheel 64 and the second worm wheel 65 are rotatably arranged on the fixed plate 30, specifically, the lower surfaces of the first worm wheel 64 and the second worm wheel 65 are fixedly connected with a cylindrical connection block, and the connection block passes through Bearings etc. are connected on the fixed plate 30, and the first worm gear 64 and the se...

Embodiment 3

[0051] This embodiment is further improved on the basis of embodiment 2, specifically, as Figure 1~2 As shown, the combined table and chair also includes a rotating device.

[0052] The rotating device includes a rotating worm 71 and a rotating worm wheel 72. The two ends of the rotating worm 71 are mounted on the upper end of the support plate 20. The upper surface of the rotating worm wheel 72 is fixedly equipped with a cylindrical projection 73. The mounting plate 40 is provided with a through hole. The bump 73 runs through the through hole and is fixedly connected to the lower surface of the test bench 50; the upper surface of the mounting plate 40 is provided with a support block 44, and the test bench 50 is placed on the support block 44; one end of the rotating worm 71 is also connected to a turntable Not shown in the figure, by rotating the turntable, the rotating worm 71 rotates, thereby driving the rotating worm wheel 72 to rotate, and the rotating worm wheel 72 dri...

Abstract

The invention discloses a combined physical experiment desk and chair, which relates to the field of physical experiment equipment. The combined physical experiment desk and chair comprises a base, amounting plate, an experiment table surface and a seat. A fixing seat is arranged on the base, a first screw rod is arranged on the fixing seat, a first slide block is slidably connected with the first screw rod, a cylinder is arranged on the first slide block, a cylinder piston rod is connected with a first pillar, the first pillar is connected with a second pillar and a third pillar and the third pillar is connected with the seat; the third pillar is threaded and connected to an auxiliary pillar; the experiment table surface comprises a first table surface, a second table surface and a thirdtable surface which are connected in sequence. The invention has the advantages that the seat can be moved back and forth and the height can be adjusted; at the same time, through the combination ofthe first table surface, the second table surface and the third table surface, different physical experiments can be carried out to meet the needs of different experiments and different grades of students. The combined physical experiment desk and chair has the advantages of simple structure, convenient operation and safe use; light weight, easy to handle in use.

Description

technical field [0001] The invention relates to the technical field of physical experiment equipment, in particular to a combined physical experiment table and chair. Background technique [0002] Physics experiment is an important means of physics teaching. It can not only deepen students' memory and understanding through sensory teaching, but also cultivate students' hands-on ability. With the continuous development of science and technology, students put forward higher requirements for the use of physical experiment tables. [0003] At present, the existing physical experiment table occupies a large area, basically every time you walk around, you can only pass through the space between the two experimental tables, and a chair should be placed between the two experimental tables to facilitate people's use, but when the chair is moved It is inconvenient, and the space reserved by the two experimental tables is limited, so every time someone wants to pass, the sitting perso...
