DETAILED DESCRIPTION

[0022] In order to make the technical solution of the present application more clearly understood by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 7In one embodiment shown, a rotating tray is movably arranged on an office desktop, including a cylindrical base 1 and a tray 2, wherein the tray 2 includes an upper tray 21 and a rotating shaft 22 which are integrally arranged, wherein the rotating shaft 22 is arranged at the bottom of one side of the upper tray 21, and a disc 6 is arranged on the upper tray 21; the rotating shaft 22 is inserted into the cylindrical base 1 and rotatably cooperates with the cylindrical base 1 through an elastic positioning member 4.

[0024] In this embodiment, the rotating shaft 22 and the cylindrical base 1 are both made of metal aluminum alloy. In order to avoid abnormal noise caused by friction between the two metal parts, a sleeve 3 is arranged between the rotating shaft 22 and the cylindrical base 1. The sleeve 3 is made of pom material and is sleeved in the cylindrical base 1. The inner wall of the sleeve 3 fits the outer peripheral surface of the rotating shaft 22, and the outer wall fits the inner wall of the cylindrical base 1. That is, when the rotating shaft 22 rotates in the cylindrical base 1, the friction between the two metals will produce a harsh abnormal noise, which affects the comfort of the product customers. The sleeve 3 made of pom material is sandwiched between the two to avoid the abnormal noise caused by direct friction between metals.

[0025] In this embodiment, an assembly hole 23 is provided at the lower part of the rotating shaft 22. The assembly hole 23 passes through the rotating shaft 22 horizontally and corresponds to the positioning hole 11 provided on the cylindrical base 1. The positioning hole 11 includes two, which correspond to the two ends of the assembly hole 23 respectively. Figure 4 As shown, the elastic positioning member 4 includes a threaded column 41 threadedly matched with the assembly hole 23 (that is, the inner wall of the assembly hole 23 is provided with an internal thread, the outer wall of the threaded column 41 is provided with an external thread, and the internal thread corresponds to the external thread), a cavity 411 is provided in the threaded column 41, and a through-port 412 connected to the cavity 411 is provided at one end of the threaded column 41 to cooperate with the installation of the positioning top bead 43 and the spring 44; the spring 44 is arranged in the cavity 411, one end of which is connected to the positioning top bead 43, and the other end is fixed to the bottom wall of the cavity 411; the positioning top bead 43 is arranged in the through-port 412, and the rotating shaft 22 and the cylindrical base 1 are limited by the engagement of the positioning top bead 43 with the positioning hole 11.

[0026] In order to facilitate the adjustment of the position of the threaded column 41, an adjustment hole 42 is provided at the other end of the threaded column 41. When the positioning ball 43 corresponds to one of the positioning holes 11, the adjustment hole 42 corresponds to the other positioning hole 11, and a hexagonal wrench can be used to enter the assembly hole 23 through the corresponding positioning hole 11 and cooperate with the adjustment hole 42 to adjust the position of the threaded column 41 (that is, the length of the positioning ball 43 at the opening 412 of the threaded column 41 extending out of the assembly hole 23).

[0027] It can be understood that the positioning bead 43 of the present application is a semicircular structure. If the positioning bead 43 is just stuck in the positioning hole 11, it can play a positioning effect and realize the positioning of the rotating shaft 22; that is, the more the threaded column 41 is turned out of the assembly hole 23 through the cooperation of the hexagonal wrench and the adjustment hole 42, the more the positioning bead 43 on the top will be stuck in the positioning hole 11, and the better the positioning effect, and vice versa. When the rotating shaft 22 rotates to other positions, the inner wall of the cylindrical base 1 will squeeze the positioning bead 43 to compress the spring 44 to contract to achieve a rotatable effect.

[0028] In addition, in order to reduce the weight of the upper tray 21 and prevent the product from sagging after installation, the present application provides a weight-reducing hole 211 on the upper tray 21, that is, the middle position of the upper tray 21 is hollowed out and the edge position is milled to achieve the purpose of product weight reduction and cost saving.

[0029] This application can design the wire box socket to be installed under the decorative tray. The tray can rotate 360 ​​degrees. When it is opened, there is a power socket underneath. When the cover is rotated, the power socket is hidden under the tray for decorative effect. This tray has the advantages of easy installation and rotation with positioning effect. Figure 5-Figure 7 As can be seen from the embodiment shown, a mounting piece 5 is provided on the side wall of the cylindrical base 1, and the assembly of the tray is achieved by fixing the mounting piece 5 with the table body mounting frame 7. A disc 6 is provided on the upper tray 21, and a wire box socket 8 is provided under the tray. When the disc 6 is removed, the wire box socket is exposed to the outside for easy plugging and unplugging. After the disc 6 is rotated and covered by rotating the tray, the desktop remains tidy and the power socket below cannot be seen, which has a decorative effect. The lifting device of the tray involved in the use of the tray in this application is arranged in the table body, which is a well-known technology in the art.
