Description

Technical Field

[0001] The utility model belongs to the field of compact cabinet frames, and in particular relates to a compact cabinet frame with significantly improved load-bearing performance. Background Art

[0002] A compact cabinet is a device used to store, manage, and protect documents, materials, and other items. It is usually composed of a sliding base, a frame, and horizontal partitions. Each horizontal partition is labeled and numbered to help users quickly find the items they need. The sliding base of a traditional compact cabinet is a rectangular structure with a length and width similar to the frame, which results in limited load-bearing capacity of the compact cabinet. When the load is too high, the compact cabinet is prone to damage, and it is prone to shaking or even tipping over when moving. In the industry, the practice of improving the load-bearing capacity of compact cabinets is usually to choose better materials, increase the overall thickness of the compact cabinet, or even increase the number of tracks to improve the smooth movement of compact cabinets with higher loads, but this will lead to a significant increase in production costs. Utility Model Content

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a compact cabinet frame with significantly improved load-bearing performance, which can improve the load-bearing performance of the compact cabinet frame while controlling the production cost.

[0004] The specific technical solution adopted in this utility model is:

[0005] A compact cabinet frame with significantly improved load-bearing performance includes a sliding base, an outer frame arranged on the sliding base, an intermediate frame arranged between the outer frames, cabinet panels arranged along the outer frames respectively, and horizontal partitions arranged between the intermediate frame and the outer frames. The key is that the sliding base includes a hollow enclosure with a trapezoidal cross-section, an upper frame and a lower frame arranged in the hollow enclosure and connected to the inner wall thereof, the width of the lower frame is greater than that of the upper frame, and plug interfaces are respectively provided on the upper and lower frames, and the outer frame is inserted into the upper and lower frames with the aid of the plug interfaces.

[0006] Limiting plates are respectively provided on the front and rear sides of the hollow enclosure. When two adjacent compact cabinets are in contact, they are limited by the two adjacent limiting plates on the hollow enclosure, and the two adjacent limiting plates are fitted together to form a triangular structure.

[0007] A sleeve corresponding to the plug-in interface is provided between the upper frame and the lower frame, and the outer frame passes through the plug-in interface and the sleeve of the upper frame in sequence and is plugged into the plug-in interface on the lower frame.

[0008] The middle frame is provided with a crossbeam and a longitudinal partition. The crossbeams are spaced in sequence along the longitudinal direction, and the upper and lower ends of the longitudinal partition are respectively connected to the crossbeam.

[0009] The length of the lower frame is the same as that of the upper frame. In the width direction, a reinforcing connecting block is provided between the hollow enclosure and the upper frame or the lower frame, and the reinforcing connecting blocks are respectively fitted with the inner wall of the hollow enclosure and the upper frame or the lower frame on both sides.

[0010] The beneficial effects of the utility model are:

[0011] In the utility model, the sliding base includes an upper frame, a lower frame with a width greater than the upper frame, and a hollow enclosure with a trapezoidal cross-section. The upper frame and the lower frame are respectively connected to the inner walls of the hollow enclosure. Only the width of the lower frame is increased and the hollow enclosure with a trapezoidal cross-section is utilized to increase the contact area between the sliding base and the ground, which helps to disperse and resist the load, provide uniform and stable support force for the compact cabinet frame, reduce the number of rails set, and improve the stability of the sliding base while controlling the production cost. Make the compact cabinet frame have better load-bearing performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0018] Specific implementation examples Figure 1-4As shown, a compact cabinet frame with significantly improved load-bearing performance includes a sliding base, an outer frame 1 arranged on the sliding base, an intermediate frame 2 arranged between the outer frames 1, cabinet panels 3 respectively arranged along the outer frame 1, and horizontal partitions 4 arranged between the intermediate frame 2 and the outer frame 1. The key point is that the sliding base includes a hollow enclosure 5 with a trapezoidal cross-section, an upper frame 6 and a lower frame 7 arranged in the hollow enclosure 5 and connected to the inner wall thereof, the width of the lower frame 7 is greater than the width of the upper frame 6, and the upper frame 6 and the lower frame 7 are respectively provided with plug-in ports 8, and the outer frame 1 is inserted into the upper frame 6 and the lower frame 7 by means of the plug-in ports 8. By increasing the width of the lower frame 7, the contact area between the sliding base and the ground is increased, the hollow enclosure 5 is respectively connected to the lower frame 7 of the upper frame 6 to form a structure with a trapezoidal cross-section, and the combination of the upper frame 6, the lower frame 7 and the hollow enclosure 5 helps to disperse and resist the load, provide uniform and stable support for the compact cabinet frame, reduce the number of rails, improve the stability of the sliding base and make the compact cabinet frame have better load-bearing performance.

[0019] When the length of an ordinary compact cabinet frame is the same as that of the compact cabinet frame of this embodiment, both are greater than four meters, and the load-bearing capacity of the two is the same, the ordinary compact cabinet frame needs to use three tracks for smooth movement, while the compact cabinet frame of this embodiment only needs two tracks for smooth movement.

[0020] Furthermore, limit plates 9 are respectively provided on the front and rear sides of the hollow enclosure 5. When two adjacent compact cabinets contact each other, they are limited by the two adjacent limit plates 9 on the hollow enclosure 5. The two adjacent limit plates 9 are fitted together to form a triangular structure. The addition of the limit plates 9 enables the two adjacent compact cabinets to be in surface contact when in contact and limited, thereby avoiding the compact cabinet frame from tipping over due to the small contact area between the hollow enclosures 5 with a trapezoidal cross-section when the compact cabinet frame carries a large weight, thereby improving the stability of the limitation.

[0021] Furthermore, a sleeve 10 corresponding to the plug-in interface 8 is provided between the upper frame 6 and the lower frame 7. The outer frame 1 passes through the plug-in interface 8 of the upper frame 6 and the sleeve 10 in sequence and is plugged into the plug-in interface 8 on the lower frame 7. The sleeve 10 improves the connection stability between the upper frame 6 and the lower frame 7, and at the same time increases the contact area between the lower end of the outer frame 1 and the sliding base, thereby improving the connection stability between the outer frame 1 and the sliding base, and providing a basis for improving the bearing performance.

[0022] Furthermore, a crossbeam 11 and a longitudinal partition 12 are provided on the middle frame 2. The crossbeam 11 is spaced in sequence along the longitudinal direction, and the upper and lower ends of the longitudinal partition 12 are respectively connected to the crossbeam 11. The middle frame 2 forms a closed frame with the help of the connection between the longitudinal partition 12 and the crossbeam 11, thereby improving the strength and torsional resistance of the middle frame 2 and avoiding the vibration of the frame due to the large span when the longer dense cabinet frame is moved with a large load.

[0023] Furthermore, the length of the lower frame 7 is the same as that of the upper frame 6. In the length direction, the hollow enclosure 5 is in surface contact with the lower frame 7 and the upper frame 6. In the width direction, a reinforcing connection block 13 is provided between the hollow enclosure 5 and the upper frame 6 or the lower frame 7, and the two sides are respectively fitted with the inner wall of the hollow enclosure 5 and the upper frame 6 or the lower frame 7. In this embodiment, a reinforcing connection block 13 is provided between the hollow enclosure 5 and the upper frame 6 and the lower frame 7. The reinforcing connection block 13 is in surface contact with the hollow enclosure 5, the upper frame 6 and the lower frame 7 respectively. The reinforcing connection block 13 is fixedly connected to the hollow enclosure 5. The hollow enclosure 5 is connected to the upper frame 6 and the lower frame 7 by means of the reinforcing connection block 13 to form a whole, so that the cross-section of the sliding base is trapezoidal, which further increases the contact area between the sliding base and the ground, further increases the bearing capacity of the sliding base, and thus helps to improve the bearing performance of the compact cabinet frame.

[0024] The utility model changes the structure of the sliding base and adds a longitudinal partition 12 on the middle frame 2 without changing the overall thickness and material of the compact cabinet frame. Without significantly increasing the production cost, it significantly improves the load-bearing performance of the compact cabinet frame, ensuring that the installed compact cabinet frame can still move smoothly when carrying heavier objects.
