Device for preventing buffer support structure of student rollover desktop board from pinching hands

[0010] The invention relates to a device for a student desk flip-type desktop board to prevent hand squeezing by a buffer support mechanism, such as figure 1 — figure 2 As shown, the bookcase is composed of a back baffle, left and right baffles, a front baffle, and a bottom horizontal plate. The left and right baffles 3 are connected to the table legs underneath, and the back baffle 2 is connected to the flip-top board 8 via a rotating device. A buffer support mechanism is installed between the left and right side baffles 3 and the flip-type desktop board 8, characterized in that the upper part of the two side baffles 3 is formed with an outer expansion bucket 31 corresponding to the buffer support mechanism. The bookcase is composed of the back baffle 2, the left and right side baffles 3, the front baffle 9 and the bottom horizontal plate. The bookcase has a large capacity and more books, which reduces the number of books on the table, which is conducive to learning and improving the classroom environment. The rear end of the desktop board 8 and the rear baffle 2 are rotated and matched by a rotating device. When students want to pick up or put a book, they can find the books in the desk bookcase by turning the rotating device upwards. There is no need to bend down, and the table top will not block the light. It is very convenient to pick up and put books. The flip-type desktop board 8 has a buffer support mechanism, and when the desktop board is turned over, it has the auxiliary force of pushing upwards, which is easy to open and not laborious; when the desktop board is closed down, there is a supporting force to slowly lower the desktop board. , Reduce impact. This kind of structure makes it easy and convenient to open the desktop board, and the speed of lowering the desktop board is slow, reducing the impact force. On the upper part of the left and right side baffles 3, there are outer expansion convex buckets 31 corresponding to the buffer support mechanism. Because the buffer support mechanism tilts when the flip-type table top 8 is closed, there are outer expansion convex buckets 31 to avoid the buffer Squeeze of the supporting mechanism by the opponent. The bottom horizontal board is the lower horizontal board 5 for placing books. The bottom horizontal board includes a lower horizontal board 5 and an upper horizontal board 4. The bookcase is composed of a back baffle 2, left and right side baffles 3, an upper horizontal plate 4, a lower book horizontal plate 5, a vertical baffle 6 and a front baffle 9 to form a stepped bookcase. The buffer support mechanism is a gas spring 15. In actual products, there are many specific technical solutions for the buffer support mechanism, mainly using gas spring 15 or damping mechanism, such as installing a gas spring under the desktop board, and all structures similar to the gas spring are within the protection scope of this patent. .
