Description

Technical Field

[0001] This application relates to the technical field of chassis, and in particular to a quick-release chassis structure. Background Art

[0002] A chassis usually consists of a cover and a chassis box. The cover is generally fixed to the chassis box by bolts and nuts. The disassembly and installation processes are cumbersome and require professional tools. Moreover, when the chassis box is already installed in a cabinet, the chassis box needs to be pulled out to remove the cover for maintenance. The convenience of removing the cover is low, resulting in low equipment maintenance efficiency.

[0003] Some quick-release cover structures have emerged on the market, but they still have complex operations and poor durability during the disassembly and installation processes;

[0004] For example, protrusions are provided on the inner wall of the cover, and grooves or clamping interfaces are provided on the side wall of the chassis box. When installing the cover, the cover is pressed downwards so that the protrusions are snapped into the grooves or clamping interfaces. During installation, it is necessary to press along the edge of the cover multiple times to ensure that all protrusions can be snapped into the corresponding grooves or clamping interfaces. Moreover, for a chassis box already installed in a cabinet, there is also the problem that the chassis box needs to be pulled out to remove the cover for maintenance. And when disassembling the cover, it is necessary to break the edge of the cover or hold the chassis box steady and then pull the cover upwards with force. The disassembly operation of the cover is complex. At the same time, applying force to open the cover multiple times easily causes the cover to deform or the protrusions to wear, and over time, it will cause the cover to not be able to be normally fixed on the chassis, resulting in poor durability. Summary of the Utility Model

[0005] In order to facilitate the quick installation and disassembly of the cover while improving the connection stability and durability between the cover and the chassis box, this application provides a quick-release chassis structure.

[0006] The quick-release chassis structure provided by this application adopts the following technical solutions:

[0007] A quick-release chassis structure includes a chassis box and a cover. Through grooves and sliding grooves are provided on the side wall of the chassis box. The through grooves penetrate through the top surface of the chassis box, and the sliding grooves communicate with the through grooves;

[0008] The cover is provided with a buckle. The buckle can be inserted into the through groove. The buckle includes a first connecting portion, a clamping portion, and a second connecting portion. Both the first connecting portion and the second connecting portion are connected to the cover. One end of each of the first connecting portion and the second connecting portion is connected to the clamping portion. Therefore, the first connecting portion can pass through the sliding groove and have a clearance fit, and the connecting portion cooperates with the side wall of the chassis box to clamp the side wall of the chassis box.

[0009] By adopting the above technical solution, when installing the machine cover, only need to move the machine cover above the chassis, align the first connecting part, the second connecting part and the clamping part with the through groove, then lower the machine cover, and then push the machine cover in the direction of closing the chassis. The first connecting part is inserted into the sliding groove while the connecting part and the side wall of the machine cover jointly clamp the side wall of the chassis. When disassembling the machine cover, only need to pull the machine cover in the direction of opening the chassis and then lift it, then the machine cover can be disassembled. Compared with the traditional quick-release structure of protrusions and grooves, it is not necessary to bend the two sides of the machine cover, the operation steps are simple, and the clamping part cooperates with the side wall of the machine cover to clamp the side wall of the chassis, performing left and right limit on the machine cover. The first connecting part cooperates with the sliding groove to realize the up and down limit on the machine cover, improving the connection stability between the machine cover and the chassis. At the same time, the first connecting part and the second connecting part jointly pull the clamping part, reducing the deformation of the clamping part and improving the durability of the machine cover.

[0010] Optionally, the first connecting part, the clamping part and the second connecting part are formed by stamping the machine cover.

[0011] By adopting the above technical solution, the first connecting part, the clamping part and the second connecting part formed by stamping are convenient for processing, have high production efficiency, and are integrated with the machine cover, featuring high connection strength and high durability.

[0012] Optionally, the size of the sliding groove is smaller than the size of the through groove, a guiding inclined surface is arranged at the junction of the sliding groove and the through groove, and the size of the first connecting part is smaller than the size of the clamping part.

[0013] By adopting the above technical solution, the guiding inclined surface has a guiding effect on the first connecting part, facilitating the insertion of the first connecting part into the sliding groove.

[0014] Optionally, a folding plate is arranged at the top of the machine cover, and the through groove penetrates through the folding plate.

[0015] By adopting the above technical solution, the folding plate reinforces the top of the side wall of the chassis, reducing the situation that the top of the side wall of the chassis is prone to deformation when the first connecting part, the clamping part and the second connecting part catch the side wall during the disassembly and installation of the machine cover.

[0016] Optionally, a plurality of buckles are provided, and a plurality of groups of the through grooves and the sliding grooves are formed on the chassis, and each buckle corresponds to a group of the through grooves and the sliding grooves.

[0017] By adopting the above technical solution, a plurality of buckles and a plurality of groups of through grooves and sliding grooves are beneficial to improving the stability of the machine cover installed on the chassis.

[0018] Optionally, a pulling groove is formed on the machine cover.

[0019] By adopting the above technical solution, the pulling groove can be hooked by hand to facilitate the pulling and lifting of the machine cover.

[0020] Optionally, limit plates are provided on both sides of the chassis, the limit plates are located at one end of the chassis, the chassis is provided with a limit slot, and after the first connecting part is inserted into the slide slot and moves a certain distance along the slide slot, the limit slot abuts against the limit plate.

[0021] By adopting the above technical solution, when the machine cover completely covers the chassis, the limit groove of the machine cover just contacts the limit plate, thereby making it convenient for personnel to judge whether the machine cover is installed completely.

[0022] Optionally, the limiting plate is connected to a mounting plate, and a plurality of fixing holes are formed on the mounting plate.

[0023] By adopting the above technical solution, the mounting plate can be connected to the cabinet, thereby facilitating the installation of the chassis in the cabinet.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Compared with the traditional quick-release structure of protrusions and slots, there is no need to bend the two sides of the cover, and the operation steps are simple. The clamping part cooperates with the side wall of the cover to clamp the side wall of the chassis to limit the left and right positions of the cover. The first connecting part cooperates with the slide groove to limit the upper and lower positions of the cover, thereby improving the stability of the connection between the cover and the chassis. At the same time, the first connecting part and the second connecting part jointly pull the clamping part to reduce the deformation of the clamping part and improve the durability of the cover.

[0026] 2. The first connection part, the clamping part and the second connection part formed by stamping are easy to process, have high production efficiency, and are integrated with the machine cover, and have the characteristics of high connection strength and high durability;

[0027] 3. The folding plate reinforces the top of the chassis side wall to reduce the possibility that the first connecting portion, the clamping portion and the second connecting portion hook onto the side wall during the removal and installation of the cover, causing the top of the chassis side wall to be easily deformed.

Detailed implementation manners

[0036] The following will Figure 1-7 Further elaborate on the present application in detail.

[0037] The embodiment of the present application discloses a quick-release type machine shell structure.

[0038] As Figure 1 , Figure 2 And Figure 3 , the quick-release type machine shell structure includes a chassis 1 and a machine cover 2. Openings are provided at both ends of the chassis 1. A sealing plate 3 is bolted to one end of the chassis 1, and a plurality of connecting ports 31 for line connection are provided on the sealing plate 3. An end plate 4 is bolted to the other end of the chassis 1, and an operation port 41 is provided on the end plate 4. Heat dissipation holes 11 are provided on both sides of the chassis 1. Limiting plates 5 are bolted to both sides of the chassis 1, and the end faces of the limiting plates 5 are flush with the end face of the end plate 4. The limiting plates 5 are connected with a mounting plate 6, and a plurality of fixing holes 61 are equidistantly provided along the length direction of the mounting plate 6. The mounting plate 6 and the limiting plate 5 together form an L-shaped plate.

[0039] As Figure 4 And Figure 5 , folding plates 12 are integrally formed at the tops of both side walls of the chassis 1. The folding plates 12 are arranged along the length direction of the chassis 1. Through grooves 13 and sliding grooves 14 are provided on both side walls of the chassis 1. The through grooves 13 penetrate through and extend out of the folding plates 12. The through grooves 13 are rectangular grooves. In other embodiments, the through grooves 13 can be circular grooves, convex grooves, etc. The sliding grooves 14 are rectangular grooves. The sliding grooves 14 communicate with the through grooves 13. The sliding grooves 14 are closer to the limiting plates 5 than the through grooves 13. The size of the sliding grooves 14 is smaller than that of the through grooves 13. A guiding inclined surface 15 is provided at the connection between the sliding grooves 14 and the through grooves 13.

[0040] As Figure 6 And Figure 7, two pulling grooves 21 are stamped on the top surface of the machine cover 2. The pulling grooves 21 are arranged at one end of the machine cover 2 close to the sealing plate 3 when the machine cover 2 is in the state of closing the chassis 1. A buckle 22 is stamped on the machine cover 2. The buckle 22 includes a first connecting portion 221, a clamping portion 222 and a second connecting portion 223. The second connecting portion 223 and the clamping portion 222 have the same width, and the width of the first connecting portion 221 is smaller than that of the clamping portion 222. The first connecting portion 221, the clamping portion 222 and the second connecting portion 223 are all concave inward in the direction of the midline of the machine cover 2. The total size of the first connecting portion 221, the second connecting portion 223 and the clamping portion 222 is smaller than the size of the through groove 13. The first connecting portion 221 can pass through the sliding groove 14 and is in clearance fit with the sliding groove 14. The clamping portion 222 cooperates with the side wall of the machine cover 2 to clamp the side wall of the chassis 1. Limit grooves 23 are opened at one end of both side walls of the chassis 1. After the first connecting portion 221 is inserted into the sliding groove 14 and moves along the sliding groove 14 for a certain distance, the limit groove 23 abuts against the limit plate 5.

[0041] Three groups of through grooves 13 and sliding grooves 14 are equidistantly arranged on both sides of the chassis 1 along the length direction of the chassis 1. Three buckles 22 are equidistantly arranged on both sides of the machine cover 2 along the length direction of the machine cover 2. Each buckle 22 corresponds to each group of through grooves 13 and sliding grooves 14 one by one.

[0042] When installing the machine cover 2, only need to move the machine cover 2 above the chassis 1, align the first connecting portion 221, the second connecting portion 223 and the clamping portion 222 with the through groove 13, then lower the machine cover 2, and then push the machine cover 2 in the direction of closing the chassis 1. The first connecting portion 221 is inserted into the sliding groove 14 and at the same time the connecting portion and the side wall of the machine cover 2 jointly clamp the side wall of the chassis 1. When the machine cover 2 completely covers the chassis 1, the limit groove 23 of the machine cover 2 just abuts against the limit plate 5, so as to facilitate the operator to judge whether the machine cover 2 is installed completely.

[0043] When disassembling the machine cover 2, only need to pull the machine cover 2 out in the direction of opening the chassis 1 and then lift it up, then the machine cover 2 can be disassembled. Compared with the traditional quick-release structure of protrusions and slots, it is not necessary to break the two sides of the machine cover 2. Its operation steps are simple, and the clamping portion 222 cooperates with the side wall of the machine cover 2 to clamp the side wall of the chassis 1, performing left and right limit on the machine cover 2. The first connecting portion 221 cooperates with the sliding groove 14 to realize the up and down limit on the machine cover 2, improving the connection stability between the machine cover 2 and the chassis 1.

[0044] At the same time, the first connecting portion 221, the clamping portion 222 and the second connecting portion 223 formed by stamping are convenient for processing, with high production efficiency, and are integrated with the machine cover 2. The first connecting portion 221 and the second connecting portion 223 jointly pull the clamping portion 222, reducing the deformation of the clamping portion 222, and having the characteristics of high connection strength and high durability.

[0045] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
