Detailed Implementation
[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0030] This embodiment relates to a modular chassis connection device, such as... Figure 1-5 As shown, the device used to connect two adjacent chassis includes: a first chassis 100, a second chassis 200, a fixing device 300, and a locking assembly 400.
[0031] Both the first chassis 100 and the second chassis 200 include side panels. A first sliding groove 110 is provided on the side panel of the first chassis 100, with an opening at one end. A second sliding groove 210 is provided on the side panel of the second chassis 200, also with an opening at one end. The second sliding groove 210 corresponds to the first sliding groove 110. The fixing device includes a first connecting part 320 and a second connecting part 330. A snap-fit groove 310 is provided between the first connecting part 320 and the second connecting part 330, and the snap-fit groove 310 respectively engages with the first sliding groove 110. 0. The second sliding groove 210 is slidably connected, and the snap-fit groove 310 can slide into the first sliding groove 110 and the second sliding groove 210 from the opening side; thereby, the first connecting part 320 and the second connecting part 330 snap the adjacent side plates of the first chassis 100 and the second chassis 200 onto the snap-fit groove 310 of the fixing device 300, completing the installation of the fixing device 300; realizing the detachable connection between the first chassis 100 and the second chassis 200, ensuring the flexibility of the connection between the two chassis. A locking component 400 is also provided between the fixing device 300 and the first chassis 100 to lock the fixing device 300 onto the first chassis 100, thereby restricting relative sliding between the fixing device 300 and the first chassis 100, so that the fixing device 300 improves the stable connection between the first chassis 100 and the second chassis 200.
[0032] In this embodiment, the first sliding groove 110 and the second sliding groove 210 are cut by laser on the side panel of the chassis. They can be designed as a cut-and-adhere structure that can be knocked off. When the connection structure is not needed, the integrity and aesthetics of the side panel of the chassis are maintained. When the connection structure is needed, it can be knocked off to form the first sliding groove 110 or the second sliding groove 210, so as to achieve a good connection effect.
[0033] In this embodiment, a first fixing member 120 is provided on the inner side of the side plate of the first chassis 100, corresponding to the inner side of the first sliding groove 110. The first fixing member 120 and the side plate of the first chassis 100 form a first space 130. When the fixing device 300 is installed, the first connecting part 320 can be accommodated in the first space 130. The locking assembly 400 is disposed between the fixing device 300 and the first fixing member 120 to lock the first connecting part 320 in the first space 130, thereby fixing the first chassis 100 and the fixing device 300 and ensuring a stable connection between the first chassis 100 and the second chassis 200.
[0034] As a preferred embodiment, the locking assembly 400 includes: a locking hole 410 disposed on the first fixing member 120, a locking seat disposed on the fixing device 300 corresponding to the locking hole 410, and a locking bolt 420 for connecting the locking hole 410 and the locking seat. The locking bolt 420 passes through the locking hole 410 and the locking seat to lock the first connecting part 320 within the first space 130, achieving a detachable connection between the first chassis 100 and the fixing device 300, ensuring flexibility in the connection between chassis. Specifically, in this embodiment, the locking seat includes: a mounting groove 430 disposed on the fixing device 300, and a locking nut 440 embedded in the mounting groove 430. The locking nut 440 can be adjusted in the mounting groove 430 according to the position of the locking hole 410 to adapt to different types of installation environments, achieving good installation results and ensuring the stability of the connection between chassis.
[0035] In this embodiment, two sets of locking components 400 are provided, corresponding to both ends of the first fixing member 120, so as to lock the first connecting part 320 at both ends of the first fixing member 120, thereby improving the locking strength of the locking components 400 to the first connecting part 320 and achieving a stable locking effect.
[0036] As a preferred embodiment, a second fastener 220 is provided on the inner side of the side panel of the second chassis 200, forming a second space 230 for accommodating the second connecting portion 330. When the fixing device 300 is installed, the second connecting portion 330 can be accommodated within the second space 230. In this embodiment, a clamping component 500 is provided between the second fastener 220 and the fastener to clamp the second connecting portion 330 against the second space 230, preventing relative sliding between the second connecting portion 330 and the second fastener 220 during chassis connection, thus affecting the connection stability between chassis.
[0037] Specifically, in this embodiment, the clamping assembly 500 includes: a fixing hole 510 disposed at one end of the second connecting portion 330, a clamping block 520 disposed above the fixing hole 510, and a fixing screw 530. The fixing screw 530 can fix the clamping block 520 above the fixing hole 510. The periphery of the clamping block 520 can abut against the end of the second fixing member 220, thereby achieving a clamping fixation between the second connecting portion 330 and the second fixing member 220. This restricts relative sliding between the fixing device 300 and the second chassis 200, enabling a detachable connection between the second chassis 200 and the fixing device 300, ensuring flexibility in the connection between the two chassis. As a preferred embodiment, two sets of clamping assemblies 500 are provided, respectively disposed at the front and rear ends of the second connecting portion 330, to clamp the second fixing member 220 from both ends of the second connecting portion 330, restricting bidirectional positional sliding of the second connecting member and achieving a good fixing effect.
[0038] In this embodiment, the first sliding groove 110 and the second sliding groove 210 have the same structure; the first fixing member 120 and the second fixing member 220 have the same structure, and a locking hole 410 is also provided at the corresponding position of the second fixing member 220. When connecting the chassis, it is not necessary to distinguish between the first chassis 100 and the second chassis 200, and the direction of the fixing device 300 does not need to be adjusted to complete the installation of the fixing device 300, thus completing the connection between the first chassis 100 and the second chassis 200. The connection process is simple and convenient. As a preferred solution, the first fixing member 120 and the second fixing member 220 are welded to the inside of the chassis to ensure the stability of the installation. At the same time, welding can be performed when connection is needed, which has a certain degree of installation flexibility.
[0039] As a preferred embodiment, the fixing device 300 has two sets of snap-fit slots 310, which are symmetrically arranged on the upper and lower sides of the fixing device 300. This allows the fixing device 300 to snap the two chassis together from the upper and lower sides, ensuring the stability of the connection and avoiding damage to the side panels of the chassis.
[0040] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
