An adjustable rack assembly

Abstract

This application discloses an adjustable frame assembly, belonging to the technical field of frame assembly. It includes four symmetrically arranged channel steel legs, each with a support column at its bottom; and a mounting frame fixedly disposed between the two channel steel legs, with two channel steel legs symmetrically arranged on each side of the mounting frame. This application utilizes a sliding support column on the inner side of the channel steel legs and adjusts the support height of the support column by incorporating an adjustment component inside the channel steel legs. This results in higher strength for the support column and adjustment component under the horizontal limiting action of the channel steel legs, requiring only the adjustment component to vertically press the support column. Therefore, it effectively solves the problem that traditional welding or bolted connections may cause cracks or even breakage during the operation of large, heavy equipment, affecting the stability of safe operation. This achieves vertical support at the bottom of the frame to prevent cracks or breakage at the stressed connection.

Description

Technical Field

[0001] This application relates to the field of rack assembly technology, and more specifically, to an adjustable rack assembly. Background Technology

[0002] Rack assemblies are standardized structural modules used to support, install, and manage electronic equipment, mechanical devices, or industrial systems. They are designed to optimize space utilization, improve equipment stability, and simplify maintenance processes.

[0003] In related technologies, for example, the prior art patent with publication number CN217003703U provides a frame adjustment mechanism. This frame adjustment mechanism, by rotating the second internal hexagonal head screw in the front and rear wedge mechanisms, causes the second internal hexagonal head screw to rotate and move inward into the force plate, thereby squeezing and driving the wedge block to move between the force plate and the foot fixing plate. This causes the wedge block to squeeze the foot fixing plate, causing the foot fixing plate to move downward to support the ground, thus raising the height of one side of the frame. By adopting the wedge structure principle, horizontal movement can be converted into vertical movement. Through the movement of the wedge block, a large lifting force can be output, thereby realizing the horizontal adjustment of the frame working surface, which is suitable for the horizontal adjustment operation of large and heavy equipment.

[0004] While the existing technical solutions described above have solved the problems mentioned in the background, the wedge mechanism, which serves as a support structure, is located on both sides of the frame. For larger and heavier equipment, the strength requirements for the connection between the frame and the wedge mechanism on both sides are relatively high. If traditional welding or bolt connections are used at the connection, cracks or even breakage may occur during the operation of the larger and heavier equipment, affecting the stability of the equipment's safe operation.

[0005] In view of this, we propose an adjustable rack assembly. Utility Model Content

[0006] The purpose of this application is to provide an adjustable frame assembly that can effectively solve the problem in the prior art that if the connection is made by traditional welding or bolting, cracks or even breakage may occur during the operation of large and heavy equipment, affecting the stability of the safe operation of the equipment. The application achieves the effect of preventing cracks or breakage of the stressed connection part by vertically supporting the bottom of the frame.

[0007] This application provides an adjustable rack assembly, comprising:

[0008] Four channel steel legs are symmetrically arranged, and each channel steel leg is provided with a support column at its bottom.

[0009] The mounting bracket is fixedly installed between the channel steel legs on both sides, and two channel steel legs are symmetrically arranged on each side of the mounting bracket.

[0010] The support frame is fixedly installed between the channel steel legs on both sides;

[0011] The adjustment component is detachably installed inside the channel steel support leg and is used to adjust the height of the support column;

[0012] The support column is slidably disposed on the inner side of the channel steel leg, and the support column is located at the bottom of the adjustment assembly, and is supported by the vertical pressure of the adjustment assembly on the channel steel leg.

[0013] As an optional solution to the technical solution of this application, the mounting frame includes two symmetrically arranged crossbeams A, and a longitudinal beam A is symmetrically fixed between the two crossbeams A. End channel steels A are fixedly installed at both ends of the crossbeams A. The end channel steels A are fixedly connected to the channel steel legs on both sides by bolts A.

[0014] As an optional solution to the technical solution of this application, the support frame includes two symmetrically arranged crossbeams B, and a longitudinal beam B is symmetrically fixed between the two crossbeams B. End channel steels B are fixedly arranged at both ends of the crossbeams B. The end channel steels B are fixedly connected to the channel steel legs on both sides by bolts A. The end channel steels B are located outside the support column and are used to limit the support column to be located inside the channel steel legs.

[0015] As an optional solution to the technical solution of this application, the adjustment component includes a fixing block, which is fixedly mounted on the inner side of the channel steel support leg by bolt C. A screw is threadedly connected to the inner side of the fixing block, and a clamping block is rotatably mounted at the bottom of the screw. The clamping block is slidably mounted on the inner side of the support column and is located at the top of the support column. An opening is provided on the inner side of the support column corresponding to bolt A.

[0018] As an optional solution to the technical solution in this application, the outer side of the channel steel support leg is provided with bolt B corresponding to the toothed plate thread.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] (1) This application adopts a support column that slides inside the channel steel leg and adjusts the support height of the support column by setting an adjustment component inside the channel steel leg. This makes the support column and adjustment component stronger under the horizontal limiting action of the channel steel leg. The adjustment component only needs to press the support column vertically. Therefore, it effectively solves the problem that if the connection is connected by traditional welding or bolts, cracks or even breaks may occur during the operation of large heavy equipment, affecting the stability of safe operation of the equipment. In this way, it realizes the prevention of cracks or breaks in the stress connection part by vertically supporting the bottom of the frame.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 This application discloses an adjustable frame assembly, including channel steel legs 1, mounting brackets 2, support frames 3, and adjustment components 4. Four channel steel legs 1 are symmetrically arranged, and each channel steel leg 1 has a support column 11 at its bottom. The mounting bracket 2 is fixedly arranged between the channel steel legs 1 on both sides, with two channel steel legs 1 symmetrically arranged on each side of the mounting bracket 2. The support frame 3 is fixedly arranged between the channel steel legs 1 on both sides. The adjustment components 4 are detachably arranged inside the channel steel legs 1 for adjusting the height of the support column 11. The support column 11 is slidably arranged inside the channel steel legs 1, and the support column 11 is located at the bottom of the adjustment components 4, supporting the channel steel legs 1 under the vertical pressure of the adjustment components 4.

[0033] By vertically sliding the support column 11 on the inner side, the corresponding support column 11 can be individually adjusted by the adjustment components 4 on the inner side of the channel steel legs 1 at the four corners. This ensures that the channel steel legs 1 remain horizontally stable as a whole. Furthermore, during the operation of larger heavy equipment, the horizontal limiting of the support column 11 and the channel steel legs 1 prevents the vibration generated by the equipment from forcing relative horizontal movement between the support column 11 and the adjustment components 4, thus preventing the adjustment components 4 from being deformed or damaged by horizontal vibration. At this time, the adjustment components 4 only need to apply pressure to the support column 11. Compared to connecting the supporting structure to the outside, the support column 11 located on the inner side of the channel steel legs 1 can prevent cracks and breaks at the fixed connection points, providing more stable support for larger heavy equipment.

[0034] Reference Figure 2 The mounting frame 2 includes two symmetrically arranged crossbeams A21, with a longitudinal beam A22 symmetrically fixed between the two crossbeams A21. End channel steels A24 are fixedly installed at both ends of the crossbeams A21, and the end channel steels A24 are fixedly connected to the channel steel legs 1 on both sides by bolts A13. Mounting holes 23 are provided on the inner sides of both the crossbeams A21 and the longitudinal beams A22. A housing 12 is detachably installed on the top of the crossbeams A21 and the longitudinal beams A22. The support frame 3 includes two symmetrically arranged crossbeams B31, with a longitudinal beam B32 symmetrically fixed between the two crossbeams B31. End channel steels B33 are fixedly installed at both ends of the crossbeams B31, and the end channel steels B33 are fixedly connected to the channel steel legs 1 on both sides by bolts A13. The end channel steels B33 are located outside the support column 11, used to limit the support column 11 from being located inside the channel steel legs 1.

[0035] When assembling the equipment, the housing 12 is fixedly mounted on the top of the mounting frame 2 by aligning it with the bottom of the mounting hole 23. Then, other components are installed inside the housing 12 in sequence. After the crossbeam A21 is connected to the equipment, the equipment is supported by the channel steel legs 1 and the column 11. The end channel steel B33 located on the outer side of the channel steel legs 1 on both sides, together with the crossbeam B31 and the longitudinal beam B32, ensures the overall stability of the frame.

[0036] Reference Figure 3 and Figure 4 The adjusting component 4 includes a fixing block 41, which is fixedly mounted on the inner side of the channel steel support leg 1 by bolts C42. A screw 43 is threadedly connected to the inner side of the fixing block 41. A clamping block 44 is rotatably mounted at the bottom of the screw 43 and slidably mounted on the inner side of the support column 11, located at the top of the support column 11. An opening 15 is provided on the inner side of the support column 11 corresponding to bolt A13. A gear sleeve 45 for driving the screw 43 to rotate is rotatably mounted on the inner side of the fixing block 41. A toothed plate 48 is meshed on the outer side of the gear sleeve 45, and a handle 49 is fixedly mounted on the outer side of the toothed plate 48. A sliding groove A46 is provided on the outer side of the screw 43 parallel to the axis. The gear sleeve 45 is slidably mounted on the outer side of the screw 43 along the sliding groove A46. A sliding groove B47 is provided on the inner side of the fixing block 41 corresponding to the gear sleeve 45, and the toothed plate 48 is slidably mounted on the inner side of the sliding groove B47. A bolt B14 is threadedly mounted on the outer side of the channel steel support leg 1 corresponding to the toothed plate 48.

[0037] When adjusting the support column 11, the toothed plate 48 is pushed and pulled along the slide groove B47 by holding the handle 49, so that the toothed plate 48 drives the inner toothed sleeve 45 of the fixing block 41 to rotate. The toothed sleeve 45 drives the screw 43 to rotate and feed inside the fixing block 41, thereby driving the clamping block 44 to move up and down at the top of the support column 11, so as to adjust the support height of the support column 11. After adjustment, in order to prevent accidental collision with the toothed plate 48 during use, the toothed plate 48 is reinforced by the bolt B14 on the outside of the channel steel leg 1 to improve the safety of use. In addition, the fixing block 41 is detachably installed on the inside of the channel steel leg 1 by the bolt C42, so as to assemble and use the adjustment component 4 with the channel steel leg 1.

[0038] In summary, when using the adjustable frame assembly disclosed in this application, after assembling the channel steel leg 1, mounting bracket 2, and support frame 3, the toothed plate 48 is pushed and pulled along the slide groove B47 by holding the handle 49. This causes the toothed plate 48 to rotate the inner toothed sleeve 45 of the fixing block 41. The toothed sleeve 45 then drives the screw 43 to rotate and feed inside the fixing block 41, thereby causing the clamping block 44 to move up and down at the top of the support column 11 to adjust the support height of the support column 11. At the same time, the level of the channel steel leg 1 is fixed in conjunction with a level. Then, the housing 12 is installed on top of the mounting bracket 2, and other components are installed inside the housing 12 in the assembly sequence, so that the crossbeam A2... 1. After being connected to the equipment, the equipment is supported by the channel steel legs 1 and the support column 11. When the equipment is running, the horizontal limiting of the support column 11 and the channel steel legs 1 prevents the vibration generated by the equipment from forcing the support column 11 and the adjustment component 4 to move horizontally relative to each other, and prevents the adjustment component 4 from being deformed and damaged by horizontal vibration. At this time, the adjustment component 4 only needs to apply pressure to the screw 43. Compared with connecting the supporting force structure to the outside, the support column 11 located on the inside of the channel steel legs 1 can prevent cracks and breaks in the fixed connection parts, and provides more stable support for larger heavy equipment. The screw 43 can be selected with different diameter specifications according to the type of equipment to meet the stable support of the equipment.
