Abstract
Description
Technical Field
[0001] This invention relates to the field of chassis and equipment technology, and in particular to a concealed chassis cover fixing buckle. Background Technology
[0002] A computer chassis typically includes an outer shell, a bracket, and a cover. The outer shell is usually made of a combination of steel plate and plastic, which has high rigidity and mainly serves to protect the internal components. Standard chassis are enclosures that conform to general and fixed dimensions and comply with national standards. They are widely used in industries such as computers, instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery.
[0003] Currently, chassis covers are generally fixed in the following ways: first, by screws; second, by clips; and third, by rivets or welding. Existing technologies have the following main problems: screw fixation leaves screw heads on the chassis's outer surface, affecting the product's appearance and compromising waterproofing; clip-on methods are generally specific to certain chassis and lack universality; and chassis components fixed by rivets and welding are generally not removable. Summary of the Invention
[0004] The purpose of this invention is to solve at least one of the problems mentioned in the background art. To achieve this purpose, the following technical solution is adopted:
[0005] A concealed chassis cover fixing buckle includes a buckle body and a buckle pin. The buckle body includes a buckle base for mounting on the chassis frame. The buckle base is equipped with a movable latch and a positioning component for controlling the reset of the movable latch. One end of the movable latch is connected to the positioning component and is fitted with an iron plate. One end of the buckle pin is fixedly connected to the inner surface of the cover to be installed. The other end of the buckle pin is provided with a snap-fit groove for snapping with the other end of the movable latch. When the buckle pin is inserted into the buckle base, the other end of the movable latch will lock the snaple pin in the snap-fit groove, and the buckle pin will be locked and cannot be pulled out.
[0006] A further improvement is that the positioning element is a spring, one end of which is connected to the buckle seat, and the other end of which is connected to one end of the movable lever.
[0007] A further improvement is that one end of the fastener is fixedly connected to the inner surface of the cover plate to be installed by a riveting method.
[0008] A further improvement is that the buckle is provided with screw holes at both ends for fixing the buckle to the chassis frame with screws, and the buckle is provided with a strip groove for the movable lever to rotate and a through hole for the buckle pin to be inserted.
[0009] A further improvement is that both the buckle and the movable lever have mounting holes, and the buckle and the movable lever are connected by a pivot passing through the mounting holes.
[0010] A further improvement is that the chassis structure includes a mounting plate, the mounting plate is provided with chamfered holes, and the mounting plate is provided with a clearance groove and a clearance hole for fasteners to pass through at the corresponding positions of the strip groove.
[0011] A further improvement is that when the spring is in its natural state, the iron sheet is in a tilted state.
[0012] A further improvement is that the cover plate, buckle, movable lever, and buckle pin are all made of aluminum alloy.
[0013] A further improvement is that the method for disassembling the buckle includes: placing a magnet on the outer surface of the cover plate at a position corresponding to the iron sheet, attracting the iron sheet with the magnet to rotate one end of the movable lever upward, while the other end of the movable lever rotates downward, so that the movable lever is no longer engaged with the locking groove, and pulling the cover plate and the buckle upward together to disengage the buckle from the buckle seat.
[0014] The beneficial effects of this invention are:
[0015] When installing the chassis cover, the other end of the fastener on the inner surface of the cover is inserted into the fastener seat and engages with the other end of the movable lever on the fastener seat, thus securing the fastener and preventing it from being pulled out. This fastener fixation secures the chassis cover. When it is necessary to remove the cover, a magnet is placed on the outer surface of the cover at the position corresponding to the metal plate. The magnet attracts the metal plate, causing one end of the movable lever to rotate upwards, while the other end rotates downwards. The movable lever is no longer engaged with the locking slot, allowing the fastener to be pulled upwards and disengaged from the fastener seat, thus removing the cover.
[0016] This invention uses fasteners to secure the chassis cover, offering the following advantages: no exposed screw heads on the chassis's outer surface, and the fasteners are completely concealed inside the chassis, resulting in an aesthetically pleasing appearance. Furthermore, the absence of exposed screw heads on the chassis's outer surface enhances waterproofing. Additionally, the movable locking lever engages the locking slot, facilitating easy installation and disassembly, and providing a simple, robust, and durable structure. Attached Figure Description

Therefore, the drawings only show the components related to the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] It should be noted that when a component is said to be "mounted" on another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms “and” and “and” as used herein include any and all combinations of one or more of the associated listed items.
[0029] Please refer to the attached document. Figure 1 -Appendix Figure 7 ,like Figure 1 , Figure 2 As shown in the figure, this embodiment of the invention proposes a concealed chassis cover fixing buckle. The fixing buckle is used for the installation between the chassis cover 6 and the chassis body (not shown in the figure). The fixing buckle includes a buckle body and a buckle pin 1. The buckle body includes a buckle seat 2 for installation on the chassis frame. The buckle seat 2 is equipped with a movable buckle 3 and a positioning component for controlling the reset of the movable buckle 3. One end of the movable buckle 3 is connected to the positioning component and is equipped with an iron piece 5. One end of the buckle pin 1 is fixedly connected to the inner surface of the cover 6 to be installed. The other end of the buckle pin 1 is provided with a snap-fit groove 7 for snapping with the other end of the movable buckle 3. When the buckle pin 1 is inserted into the buckle seat 2, the other end of the movable buckle 3 will snap into the snap-fit groove 7 of the buckle pin 1, and the buckle pin 1 will be locked and cannot be pulled out.
[0030] The method for disassembling the buckle 1 includes: placing a magnet (not shown in the figure) on the outer surface of the cover plate 6 at a position corresponding to the iron piece 5, attracting the iron piece 5 with the magnet to make one end of the movable latch 3 rotate upward, while the other end of the movable latch 3 rotates downward, so that the movable latch 3 is no longer engaged with the latching groove 7, and pulling the cover plate 6 and the buckle 1 upward together to make the buckle 1 disengage from the buckle seat 2.
[0031] The installation principle of this embodiment is as follows: When installing the chassis cover 6, the other end of the fastener 1 on the inner surface of the chassis cover 6 is inserted into the fastener seat 2 and engages with the other end of the movable lever 3 on the fastener seat 2, thereby fixing the fastener 1 and preventing it from being pulled out. The chassis cover 6 is thus fixed by fixing the fastener 1. When it is necessary to remove the cover 6, a magnet (not shown in the figure) is placed on the outer surface of the cover 6 at the position corresponding to the iron piece 5. The magnet attracts the iron piece 5, causing one end of the movable lever 3 to rotate upwards, while the other end of the movable lever 3 rotates downwards. The movable lever 3 is no longer engaged with the engaging groove 7, and the fastener 1 can be pulled upwards and disengaged from the fastener seat 2, thus achieving the removal of the cover 6. Figure 2 The diagram shows the structure of a concealed chassis cover fixing clip of the present invention, in which an iron piece 5 is attracted by a magnet. The magnet is preferably a strong magnet.
[0032] Understandably, in practical use, multiple sets of fixing buckles can be configured on a single cover plate 6, for example, four sets of fixing buckles, respectively located at the four corners near the cover plate 6. By setting multiple sets of fixing buckles, the cover plate 6 becomes more stable. When disassembling the cover plate 6, the movable lever 3 can be separated from the locking groove 7 by using four sets of magnets to attract the iron pieces 5 of the four sets of fixing buckles, allowing the buckle 1 to detach from the buckle seat 2.
[0033] The fixing buckle in this embodiment of the invention secures the chassis cover 6, which has the following advantages: there are no exposed screw heads on the outer surface of the chassis, and the fixing buckle is completely hidden inside the chassis, resulting in an aesthetically pleasing appearance. Furthermore, the absence of exposed screw heads on the outer surface of the chassis improves waterproofing. Additionally, the movable latch 3 engages the snap-fit groove 7, resulting in a simple, robust, and durable structure.
[0034] This invention uses an internal iron sheet 5 that works in conjunction with an external magnet. Compared to traditional magnetic fixation methods, this invention avoids using magnetic components inside the chassis, reducing costs. More importantly, since there are no magnetic components inside the chassis, it has high electromagnetic compatibility.
[0035] In this embodiment, the positioning element is a spring 4, such as... Figure 1 As shown, one end of the spring 4 is connected to the buckle 2, and the other end of the spring 4 is connected to one end of the movable lever 3. When the magnet on the outside of the chassis is removed, the spring 4 returns to its original state, which can drive the movable lever 3 to reset.
[0036] In this embodiment, one end of the fastener 1 is fixedly connected to the inner surface of the cover plate 6 to be installed by a press-fitting method. Specifically, a press can be used to press the hexagonal head of one end of the fastener 1 into a pre-drilled hole on the inner surface of the cover plate 6, causing plastic deformation around the hole and riveting one end of the fastener 1 to the inner surface of the cover plate 6. By using a press-fitting method to fix the fastener 1 on the inner surface of the cover plate 6, the manufacturing process is simple.
[0037] Furthermore, the mounting bracket 2 adopts a narrow and elongated design, which minimizes its space occupation inside the chassis. The structure of this invention is highly versatile; besides being used in aluminum alloy chassis, it can also be used in other non-ferromagnetic devices and equipment.
[0038] In this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the buckle 2 has screw holes 8 at both ends for fixing the buckle 2 to the chassis frame with screws 9. The buckle 2 has a strip groove 10 for rotating the movable latch 3 and a through hole 11 for inserting the buckle 1.
[0039] It is understood that the size of the strip groove 10 matches the size of the movable locking rod 3, so that the movable locking rod 3 has enough space to rotate. One side of the through hole 11 is connected to the strip groove 10, so that the other end of the movable locking rod 3 can be engaged with the annular groove on the fastener 1.
[0040] In this embodiment, as Figure 7As shown, both the buckle 2 and the movable lever 3 are provided with mounting holes 12. The buckle 2 and the movable lever 3 are connected by a rotating shaft 13 passing through the mounting holes 12, so that the movable lever 3 can rotate around the rotating shaft 13.
[0041] In this embodiment, as Figure 5 As shown, the chassis structure includes a mounting plate 14, which is mounted on the chassis. The mounting plate 14 has chamfered holes, and at positions corresponding to the strip-shaped through groove 10, it has clearance grooves 15 and clearance holes 16 for the fastener 1 to pass through. This design secures the fastener 2 without obstructing the movement of the movable lever 3 and the fastener 1.
[0042] Specifically, in this embodiment, when the spring 4 is in its natural state, the iron plate 5 is in an inclined state. That is, the iron plate 5 forms an inclined surface relative to the buckle 2. When the iron plate 5 is attracted by the magnet outside the chassis, the iron plate 5 rotates and becomes basically parallel to the buckle 2 after rotation.
[0043] Specifically, in this embodiment, the iron sheet 5 and the movable lever 3 are fixed together by screws 9.
[0044] In this embodiment, the cover plate 6, the buckle 2, the movable latch 3, and the buckle 1 are all made of aluminum alloy. Aluminum alloy has good heat dissipation and will not affect the attraction of the magnet to the iron sheet 5.
[0045] Existing technology typically places screw 9 at the bottom of the chassis for locking, requiring the chassis to be flipped over to remove screw 9, which is inconvenient. The invention uses a magnet to attract the iron piece 5 from the top of the cover plate 6 for removal, allowing for removal even when the chassis is in its normal position, making disassembly much easier and faster. The fixing clip in this invention is small in overall size, easy to install, and highly versatile.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
