[0022] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a laboratory equipment rack includes a base 1, a vertical rod 2, and a work tray 3. The base 1 is a circular base, the vertical rod 2 is a cylindrical rod, and the vertical rod 2 is connected to the center of the base 1. The work tray 3 is connected to the vertical rod 2 and is circular. The work tray 3 has a first hanging hole 301 for hanging the hook of a pipette. The outer circumferential side wall of the work tray 3 has a first limiting groove 302, which corresponds to the position of the first hanging hole 301 and is located outside the first hanging hole 301. When the pipette hook is hung in the first hanging hole 301, the body of the pipette is located in the first limiting groove 302, thereby limiting the body of the pipette and the pipette is stably hung on the work tray 3. The working tray 3 is provided with multiple first hanging holes 301 arranged in a circular array. Correspondingly, multiple first limiting grooves 302 are also arranged in a circular array. In this embodiment, there are six first hanging holes 301 and six first limiting grooves 302, which can hang six pipettes. The upper end of the upright 2 is connected to a bearing 6 (the upper end of the upright 2 is provided with a small-diameter rod segment, which corresponds to the inner diameter of the bearing 6). The working tray 3 is sleeved on the bearing 6, so that the working tray 3 and the upright 2 are rotatably connected. The pipettes can be rotated, which facilitates the picking up and placing of the pipettes.

[0024] like Figure 1 and Figure 3 As shown, a second limiting groove 303 is provided on the outer circumferential sidewall of the working disk 3. The second limiting groove 303 extends from the outer circumferential sidewall of the working disk 3 towards the center of the working disk 3. A hanging plate 4 is provided inside the second limiting groove 303. The hanging plate 4 is arranged radially along the working disk 3. The thickness of the hanging plate 4 gradually decreases from the inside to the outside, and the outermost end of the hanging plate 4 is also located inside the second limiting groove 303, so as not to protrude from the outer circumferential side of the working disk 3. In use, the hanging plate 4 is used to hang tweezers. The tweezers are picked up vertically, the gap in the middle of the tweezers is aligned with the hanging plate 4 and moved into the second limiting groove 303. The tweezers are hung on the hanging plate 4 and their position is restricted by the second limiting groove 303. Multiple second limiting grooves 303 are distributed in a ring array on the outer circumferential sidewall of the working disk 3. In this embodiment, six second limiting grooves 303 are provided, so that six tweezers can be hung.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the base 1 has a first planar segment 101, which is formed by cutting off a section from the circular base 1. Two sections of the first planar segment 101 are provided, symmetrically arranged. The work tray 3 has a second planar segment 31, which is also formed by cutting off a section from the circular work tray 3. Two sections of the second planar segment 31 are also provided, their positions corresponding to the first planar segment 101. When the rack is laid down on the worktable, the worktable is horizontal. Since both the base 1 and the work tray 3 are circular, they can roll on the worktable. When the first planar segment 101 and the second planar segment 31 contact the worktable, the base 1, along with the fixed upright 2, no longer rotates. Although the work tray 3 and the upright 2 are movably connected, the work tray 3 also stops rotating because the second planar segment 31 contacts the worktable, and the rack is fixed to the worktable. The upright 2 is parallel to the workbench surface. Multiple second working grooves 201 are provided on the outer circumferential side wall of the upright 2. The second working grooves 201 are annular grooves with rectangular cross-sections. The multiple second working grooves 201 are arranged at equal distances vertically. In addition to the first working state when the rack is set vertically, there is also a second working state. When the rack is set horizontally, the second working grooves 201 form a place for placing equipment. The second working grooves 201 can fix the position of equipment such as tweezers, scissors, and knives. When using, the equipment is placed in the corresponding second working groove 201.

[0026] like Figure 1 and Figure 4As shown, the base 1 includes a first base body 11 and a second base body 12. The first base body 11 and the second base body 12 are detachably connected. The thickness of the first base body 11 and the second base body 12 is half the thickness of the entire base 1. A boss 121 is provided on one side of the second base body 12. The first base body 11 is provided with a groove corresponding to the boss 121. The boss 121 is provided with an external thread. The groove of the first base body 11 is provided with an internal thread corresponding to the external thread of the boss 121. The second base body 12 is detachably connected to the first base body 11 by a threaded connection. After the first base body 11 and the second base body 12 are threadedly connected, they are stacked to form the entire base 1. A central rod 5 is also connected to the side of the protrusion 121 of the second seat 12. The upright 2 has a central blind hole corresponding to the central rod 5. When the second seat 12 is connected to the first seat 11, the central rod 5 is located in the central blind hole of the upright 2. The central blind hole can accommodate the central rod 5. The central rod 5 has multiple third working grooves 51, which are continuously distributed on the side wall of the central rod 5. The cross-section of the third working grooves 51 is arc-shaped. When the rack is laid down on the workbench, the second seat 12 is rotated to separate it from the first seat 11, and the central rod 5 is pulled out to a certain length. At this time, the first flat section 101 on the first seat 11 and the first flat section 10 on the second seat 12 are connected. 1. The second plane segment 31 is placed on a horizontal plane, so that the entire rack is placed stably on the workbench. At this time, the third working slot 51 faces upward. Multiple third working slots 51 form a second position for placing equipment besides the second working slot 201. Tweezers, scissors, knives and other equipment can be placed on the third working slot 51. The third working slot 51 can fix the position of the equipment to prevent it from sliding, making it easy for the staff to take it. The depth of the third working slot 51 is different from the depth of the second working slot 201, and the width of the third working slot 51 is different from the width of the second working slot 201. The staff can choose to place the equipment on the third working slot 51 or the second working slot 201 according to the size and shape of the equipment.

[0027] In this embodiment, when the equipment rack is placed vertically on the workbench, the first hanging hole 301 and the first limiting groove 302 cooperate to hang a pipette, and the hanging plate 4 can vertically hang tweezers. When the rack is placed horizontally on the workbench, the first base 11 and the second base 12 are separated, and a certain length of the center rod 5 is pulled out. The first flat section 101 on the first base 11 and the second base 12, as well as the second flat section 31 of the work plate 3, contact the workbench to stabilize the entire rack. Tweezers, scissors, knives, and other equipment can be placed in the second working groove 201 and the third working groove 51.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
