Specific implementation mode

Technical scheme of the present invention is described further below in conjunction with attached drawing, but required protection domain does not limit to In described；

The present invention provides a kind of classroom desk chair systems convenient for proper alignment, as shown in Figure 1, Figure 2, Figure 3, Figure 4, packet Desk 1, chair 2 and multigroup positioning device are included, there is desk 1 table leg 101, chair 2 to have chair leg 201, table leg 101 and chair leg 201 bottoms are mounted on multi-directional ball 3, and positioning device is installed on the ground of classroom and is arranged as matrix, and every group of positioning device is by two Block locating piece 4 forms, within every group of positioning device between two pieces of locating pieces 4 spacing with adjacent two on the same desk 1 or chair 2 Table leg 101 or 201 spacing of chair leg are equal, and the first anchor ear 5 and the second anchor ear 6, the first anchor ear 5 are hinged on every piece of locating piece 4 It is linked together by fastener with 6 other end of the second anchor ear.

Using technical solution provided by the invention, positioning device overall volume is smaller, facilitates student on duty to classroom ground It is cleaned, when arranging tables and chairs, tables and chairs only need to be pushed to the position abutted with locating piece, then pass through the first anchor ear and second armful Tables and chairs leg or chair leg are fixed for the connection of hoop, make desk and tablet chair nature marshalling, operation are facilitated, for connecting The fastener of the first anchor ear and the second anchor ear is connect when loosening due to linking together with the first anchor ear, is effectively prevented tight Firmware is lost, and student on duty is facilitated to operate.
