The rotary quick-release sealing assembly 7 and the positioning assembly 8 are respectively connected. The sealing component 7 and the positioning component 8 are respectively set at the outer ends of the steel structure pull rivet of the main support plate 3. The mounting bracket 1 is L-shaped and is connected to the side panel of the cabinet through two sets of pre-reserved elongated oval mounting holes. The main support plate 3 is U-shaped with high strength. The main support plate 3 is used to support, position and guide the handcart. The front interlock bracket 4 and the rear interlock bracket 5 are L-shaped and U-shaped respectively. The front interlock bracket 4, the rear interlock bracket 5 and the small sealing plate 6 are all made of aluminum zinc plate without coating. The rotary quick-release sealing component 7 is set on the outer wall of the main support plate 3. The positioning component 8 is set on the outer wall of the main support plate 3 and is set next to the rotary quick-release sealing component 7.

[0020] The rotary quick-release sealing assembly 7 includes a fixing seat 701 welded to the outer side of the steel structure pull rivet of the main support plate 3. Two sets of fixing seats 701 are spaced apart. A connecting shaft 702 is rotatably mounted inside each set of fixing seats 701. A mounting block 703 is welded between the two sets of connecting shafts 702. A rectangular groove is formed on one side of the mounting block 703. A guide rod 704 is welded to the inner wall of the rectangular groove of the mounting block 703. Two sets of L-shaped insertion blocks 705 are slidably mounted on the guide rod 704. A spring 706 is fitted on the 04 and is positioned between two sets of L-shaped plug blocks 705. A plug block 707 is positioned outside the two sets of L-shaped plug blocks 705. The plug block 707 has a plug hole inside and the two sets of L-shaped plug blocks 705 are positioned inside the plug hole of the plug block 707. A sealing box 708 is welded to one side of the outer wall of the plug block 707. The sealing box 708 is fitted outside the steel structure pull rivet of the main support plate 3. A sealing ring 709 is adhered to the sealing box 708 and is attached to the outer wall of the main support plate 3.

[0021] The positioning component 8 includes a fixing post 801 welded to the other side of the steel structure core-pulling rivet on the main support plate 3. A positioning block 802 is rotatably mounted on the fixing post 801. An arc-shaped groove is opened at the bottom end of the positioning block 802. A positioning rod 804 is welded to the outer wall of the main support plate 3. The positioning rod 804 is engaged inside the arc-shaped groove of the positioning block 802. A Z-shaped connecting block 803 is welded to the other side of the outer wall of the sealing box 708. The Z-shaped connecting block 803 is located in the gap between the positioning block 802 and the main support plate 3.

[0022] In this utility model, the main support plate 3 can be connected to the connecting bracket 2, the front interlocking bracket 4, and the rear interlocking bracket 5 respectively through steel structure blind rivets. The front interlocking bracket 4 and the rear interlocking bracket 5 can be connected to the cabinet to provide auxiliary fixation for the main support plate 3. The front interlocking bracket 4 and the rear interlocking bracket 5 are connected to the small sealing plate 6 through steel structure blind rivets, thereby providing stability for the front interlocking bracket 4 and the rear interlocking bracket 5. The mounting bracket 1 is connected to the connecting bracket 2 through countersunk screws, providing the main support and fixation for the main support plate 3. At this time, the main support plate 3 can ensure that the handcart moves smoothly and steadily on the guide rail during the process of moving the handcart in and out of the cabinet. Especially after the handcart enters the working position, it can effectively suppress the adverse factors caused by the handcart tilting backward. In order to prevent the steel structure blind rivets on the main support plate 3 from rusting due to contact with moisture, the rotating quick-release sealing component 7 and the positioning component 8 can be used to seal and protect the steel structure blind rivets.

[0023] When the sealing ring 709 on the sealing box 708 needs to be replaced periodically, the L-shaped plug 705 on the guide rod 704 is pressed to displace within the rectangular groove of the mounting block 703. The L-shaped plug 705 is no longer compressed by the spring 706 outside the guide rod 704. When the two sets of L-shaped plugs 705 move closer together during this displacement, the plug 707 on the sealing box 708 can be pulled out from the outside of the two sets of L-shaped plugs 705. The sealing box 708 can then be removed from the two sets of L-shaped plugs 705, allowing for the replacement of the new sealing box 708. This ensures that the sealing ring 709 on the new sealing box 708 provides an effective seal. The new sealing ring 709 is then fixed to the outside of the L-shaped plug 705 by the plug 707. After connection, the mounting block 703 is rotated by the connecting shaft 702 inside the fixed seat 701, so that the new sealing box 708 rotates synchronously and is fitted onto the outside of the steel structure pull rivet, so that the sealing ring 709 of the new sealing box 708 fits against the outer wall of the main support plate 3 to achieve a sealing effect. When the Z-shaped connecting block 803 on the outer wall of the sealing box 708 rotates to the designated position, the positioning block 802 on the fixed column 801 is rotated to make the Z-shaped connecting block 803 between the main support plate 3 and the positioning block 802. The positioning block 802 limits the Z-shaped connecting block 803, thereby fixing the position of the sealing box 708. When the arc groove of the positioning block 802 passes through the soft material of the metal, it is engaged with the positioning rod 804, thereby fixing the position of the positioning block 802.
