Description

Technical Field

[0001] The utility model relates to the technical field of laboratory tables, in particular to a foldable multi-person collaborative laboratory table. Background Art

[0002] In the current education system, teamwork and practical operation are increasingly valued. For this reason, a hexagonal laboratory table is designed as a table, aiming to promote close sitting among students through its unique shape, and effectively enhance teamwork and organizational ability. However, this innovative design also exposes some problems in practical application. Specifically, although the hexagonal laboratory table can maximize the use of space and achieve seamless communication between students, its large desktop area directly leads to the compression of the distance between adjacent laboratory tables. Under the compact classroom layout, this design not only limits the freedom of students' activities during class breaks, but also increases safety hazards invisibly, especially when students play and fight during class breaks. The narrow aisles are very likely to cause collision accidents, which not only affects the physical and mental health of students, but also may cause damage to the laboratory table itself, thereby affecting subsequent learning activities. Therefore, the development of a new foldable multi-person collaborative laboratory table that can maintain the advantages of teamwork and take into account space utilization and safety has become a technical problem that needs to be solved in the current education field.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, the utility model provides a foldable multi-person collaborative laboratory table, including a support seat 10 and a folding desktop 20, the support seat 10 includes a base 11, the top of the base 11 is provided with a supporting square tube 12, the bottom of the base 11 is provided with a flange 13, the flange 13 is fixed to the ground by bolts, the folding desktop 20 includes a first desktop 21, the first desktop 21 is hexagonal, each side of the first desktop 21 is hinged with a second desktop 22, the two sides of the second desktop 22 in the width direction are hinged with third desktops 23, the two adjacent third desktops 23 are hinged to each other, and the bottom center of the first desktop 21 is provided with a mounting portion 21 01. A plurality of fixing plates 2102 are arranged along the edge of the mounting portion 2101. The fixing plates 2102 are fixedly arranged on the outer side of the supporting square tube 12. A driving assembly 30 is arranged between the supporting square tube 12 and the folding desktop 20. A control switch 40 is arranged on the top of the first desktop 21. The control switch 40 is electrically connected to the driving assembly 30. The folding desktop 20 can be unfolded and folded by controlling the control switch 40 with one button, so that it can be retracted during class breaks, increasing the spacing between adjacent laboratory tables and ensuring sufficient space for playing and frolicking to prevent climbing and collision accidents. It can also be quickly unfolded with one button during class to avoid affecting subsequent learning activities.

[0023] like Figure 3 As shown, an upper connecting plate 1201 is provided on the inner side of the supporting square tube 12 near the top, and a lower connecting plate 1202 is provided on the inner side near the bottom, and through holes are coaxially provided on the tops of the two.

[0024] like Figure 4 As shown, the drive assembly 30 includes a drive motor 31, a transmission seat 33 and a screw rod 32. The screw rod 32 is movably arranged at the through hole between the upper connecting plate 1201 and the lower connecting plate 1202. The transmission seat 33 is located between the upper connecting plate 1201 and the lower connecting plate 1202. The drive motor 31 is arranged on the mounting portion 2101, and its output shaft is fixedly connected to the top of the screw rod 32. The transmission seat 33 is threadedly connected to the screw rod 32. The outer side of the transmission seat 33 is hinged with a first support rod 34 equal to the number of the second desktop 22. A secondary connecting rod 35 is arranged between the first desktop 21 and the second desktop 22, and the other end of the first support rod 34 is hinged to the secondary connecting rod 35.

[0025] As a preferred embodiment, a ball bearing 14 is provided at the through hole of the lower connecting plate 1202, and the bottom end of the screw rod 32 is connected to the ball bearing 14. Since the support for the folding table top 20 is mainly through the first support rod 34 to gather the force points on the transmission seat 33, and the downward pressure of the screw rod 32 on the lower connecting plate 1202 is the greatest, the friction between the screw rod 32 and the through hole of the lower connecting rod is also greater. The friction can be reduced by the ball bearing 14, thereby increasing the smoothness of the rotation of the screw rod 32 between the upper connecting plate 1201 and the lower connecting plate 1202.

[0026] In this embodiment, the outer circumference of the transmission seat 33 is equally divided into hinge ears 3301 with the same number as the second table top 22. The hinge ears 3301 are hinged to the first support rod 34. The outer wall of the supporting square tube 12 is provided with a plurality of movable grooves 1203. When the transmission seat 33 moves in the length direction of the screw rod 32, the first support rod 34 moves in the movable groove 1203.

[0027] like Figure 5 As shown, the secondary connecting rod 35 includes a first connecting rod 3501, one end of the first connecting rod 3501 is hinged on the mounting portion 2101, and the other end is hinged with a second connecting rod 3502, and the other end of the second connecting rod 3502 is hinged at the bottom center of the second desktop 22, and one end of the first support rod 34 is hinged to the middle part of the first connecting rod 3501. When the driving motor 31 drives the screw rod 32 to rotate, the transmission seat 33 moves in the length direction of the screw rod 32. At this time, the first support rod 34 drives the first connecting rod 3501 to rotate along the hinge axis between it and the first desktop 21, thereby driving the second connecting rod 3502, thereby completing the expansion and contraction.

[0028] In one embodiment, the control switch 40 is a touch switch. Compared with a mechanical button type, a touch switch is easier to maintain in the same plane as the first desktop 21, thereby increasing the aesthetics. At the same time, the touch switch has no corresponding gap and will not malfunction due to water splashing. At the same time, a long press unlocking function can be added to avoid accidental contraction caused by accidental touch during class.

[0029] Specifically, the working principle of this foldable multi-person collaborative experimental table is as follows: when it needs to be unfolded or folded, the forward and reverse rotation of the driving motor 31 is controlled by the control button, thereby controlling the transmission seat 33 to move in the length direction of the screw rod 32, wherein when it needs to be unfolded, the transmission block moves upward, so that the first support rod 34 supports the first connecting rod 3501 to rotate along the hinge axis between it and the first desktop 21, thereby driving the second connecting rod 3502, and the second connecting rod 3502 supports the second desktop 22 outward, and when the transmission seat 33 moves to contact with the upper connecting plate 1201, the second desktop 22 and the third desktop 23 are fully unfolded to be in the same plane as the first desktop 21, that is, the unfolding is completed, and when it needs to be folded, the driving motor 31 can be rotated in the opposite direction, and the folding is completed when the transmission seat 33 conflicts with the lower connecting plate 1202. The above structure solves the problem that the desktop area of ​​the existing hexagonal experimental table is large, resulting in a compact classroom layout, limiting the freedom of students in courseware activities, and at the same time, it is easy to collide with the experimental table during class breaks.

[0030] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
