Description

Technical Field

[0001] This utility model relates to the field of computer chassis technology, and in particular to a fixing mechanism for a computer chassis cover. Background Technology

[0002] As part of a computer, the computer case is primarily used to house and secure various computer components, serving to support and protect them. A computer case generally includes an outer shell, a support frame, and a cover. The outer shell is typically made of a combination of steel and plastic, offering high rigidity and providing storage space, primarily protecting the internal components. The cover, on the other hand, seals the outer shell and can be detached from it to facilitate maintenance of the internal components.

[0003] Currently, computer case covers are typically clipped onto the case opening and secured with screws around the perimeter. However, this method requires specialized tools (such as screwdrivers) to open or install the cover each time, which is time-consuming and labor-intensive. Users need to possess the necessary tools, and the screws are easily lost after being removed, increasing workload and impacting the efficiency of computer case maintenance. Utility Model Content

[0004] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing mechanism for a computer chassis cover, comprising:

[0006] The chassis has mounting ports;

[0007] A cover plate is movably installed at the mounting opening to close the chassis; the cover plate has a mounting shoulder on its side wall.

[0008] A locking assembly is located at the mounting opening of the chassis to lock and fix the cover plate. The locking assembly includes a locking shaft and a locking tongue fixed on the locking shaft. The locking shaft is located in a through hole of the chassis. The through hole is divided from top to bottom into a polygonal cross-section limiting cavity, a first receiving cavity, a rotating cavity for the locking tongue to rotate, a connecting cavity, and a second receiving cavity. The upper end of the locking shaft has a limiting head that matches the shape of the limiting cavity, and its lower end has an anti-disengagement head located in the second receiving cavity. The side wall of the rotating cavity has a slot that extends through to the mounting opening to allow the locking tongue to extend. The locking tongue rotates out of the slot and presses against the mounting shoulder to fix the cover plate.

[0009] A fixing component is disposed on one side of the limiting cavity to fix the limiting head.

[0010] Preferably, the diameter of the locking shaft is the same as the diameter of the first receiving cavity and the connecting cavity, and the diameter of the anti-detachment head is larger than the diameter of the locking shaft.

[0011] Preferably, the fixing component includes a fixing pin and an elastic element. A fixing groove is provided on the chassis on one side of the limiting cavity. The fixing pin is slidably disposed in the fixing groove, and a spring is provided between the end of the pin facing away from the limiting cavity and the wall of the fixing groove. A notch is opened on the top surface of the limiting head, and the fixing pin extends out of the fixing groove and is located on the notch under the action of the spring. A sliding groove is opened at the upper part of the fixing groove, extending to the surface of the chassis. A sliding slider is disposed in the sliding groove, and the bottom of the slider is fixed to the fixing pin.

[0012] Preferably, the slider does not protrude from the surface of the chassis.

[0013] Preferably, the side wall of the limiting head has a positioning hole that matches the shape of the fixing pin.

[0014] Preferably, the end of the positioning hole facing the fixing pin is provided with a relief portion, and the diameter of the relief portion gradually decreases from the fixing pin toward the positioning hole.

[0015] Preferably, the upper surface of the cover plate has a shielding strip extending outward.

[0016] This utility model has at least the following beneficial effects: The chassis of this utility model provides a space for installing various accessories and protecting them. The mounting opening exposes the chassis, allowing users and maintenance personnel to inspect and maintain the accessories inside. The cover is movably installed at the mounting opening to close it, thereby closing the chassis. The locking assembly is used to lock and fix the cover, preventing it from coming loose from the mounting opening. Specifically, the polygonal cross-section of the limiting cavity cooperates with the limiting head to effectively fix the locking shaft, preventing unintentional rotation of the locking shaft and thus preventing unintentional rotation of the locking tongue from releasing the lock on the mounting shoulder of the cover. The rotation of the locking shaft drives the locking tongue to rotate in the rotary cavity. The rotating locking tongue unscrews the slotted cover and presses it onto the mounting shoulder, thus fixing the cover. The anti-loosening head at the lower end of the locking shaft cooperates with the second receiving cavity to effectively prevent the locking shaft from being completely pulled out when the user pulls the limiting head upwards. The fixing assembly is used for... The fixed limiting head prevents unintentional outward pulling, further improving the locking stability of the cover and ensuring the stability of the fixing mechanism in multiple directions. When the cover needs to be removed, the fixing component is operated to release the axial restriction on the limiting head, allowing the limiting head to be pulled outward and separated from the limiting cavity. Then, the limiting head is rotated, causing the adjusting shaft to rotate the locking tongue. The locking tongue rotates back into the rotating cavity, releasing the restriction of the locking tongue on the mounting shoulder, allowing the cover to be removed from the mounting opening for maintenance. When the cover needs to be installed, the cover is placed at the mounting opening, and the locking shaft is rotated so that the locking tongue rotates out and is positioned above the mounting shoulder. Then, the limiting head is placed back into the limiting cavity. At this time, the locking tongue presses downward on the mounting shoulder, locking the cover and preventing it from falling off the mounting opening. At the same time, the fixing component is operated to fix the limiting head, preventing it from accidentally sliding out of the limiting cavity.

[0017] By employing this utility model, the locking shaft, locking tongue, limiting head, and limiting cavity work together to install or remove the cover plate without the need for additional professional tools to tighten or loosen screws. The operation is simple and convenient, improving installation and disassembly efficiency and facilitating the maintenance of internal components of the chassis. At the same time, the locking components will not be removed from the chassis when the cover plate is removed, and the locking shaft will not be lost. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0029] See Figures 1 to 8 A fixing mechanism for a computer case cover, comprising:

[0030] The chassis 100 has a mounting port 110. The chassis 100 provides space for installing various components and protects the components. The mounting port 110 exposes the chassis so that users and maintenance personnel can inspect and maintain the various components inside the chassis 100 through the mounting port 110.

[0031] A cover plate 200 is movably installed at the mounting opening 110 to close the chassis 100; a mounting shoulder 210 is provided on the side wall of the cover plate 200;

[0032] A locking assembly 300 is located at the mounting opening 110 of the chassis 100 to lock and fix the cover plate 200. The locking assembly 300 includes a locking shaft 310 and a locking tongue 320 fixed on the locking shaft 310. The locking shaft 310 is located in the through hole 120 of the chassis 100. The through hole 120 is divided from top to bottom into a polygonal cross-section limiting cavity 121, a first receiving cavity 122, a rotating cavity 123 for the locking tongue 320 to rotate, a connecting cavity 124, and a second receiving cavity 125. The upper end of the locking shaft 310 has a shape that matches the limiting cavity 121. The limiting head 311 has a locking head 312 located at the lower end within the second receiving cavity 125; the side wall of the rotating cavity 123 has a slot 126 extending through to the mounting opening 110 for the locking tongue 320 to extend out, the locking tongue 320 rotating out of the slot 126 to cover and press against the mounting shoulder 210 to fix the cover plate 200; preferably, the limiting cavity 121 has a quadrilateral cross section, and correspondingly, the limiting head 311 is also quadrilateral; it should be understood that the number of locking components 300 is preferably four, and the four locking components 300 are distributed around the mounting opening 110 of the chassis 110;

[0033] A fixing component 400 is disposed on one side of the limiting cavity 121 to fix the limiting head 311.

[0034] Specifically, the cover plate 200 is movably installed at the mounting opening 110 to close the mounting opening 110, thereby closing the chassis 100; the locking assembly 300 is used to lock and fix the cover plate 200, preventing the cover plate 200 from loosening from the mounting opening 110. Specifically, the polygonal cross-section of the limiting cavity 121 cooperates with the limiting head 311 to effectively fix the locking shaft 310, thereby preventing the locking shaft 310 from rotating unintentionally, thus preventing the locking tongue 320 from rotating unintentionally and releasing the lock on the mounting shoulder 210 of the cover plate 200. The rotation of the locking shaft 310 thereby... The movable locking tongue 320 rotates within the rotary cavity 123, and the rotating locking tongue 320 rotates out of the slot 126 to press against the mounting shoulder 210, thereby fixing the cover plate 200; the anti-disengagement head 312 at the lower end of the locking shaft 310 cooperates with the second receiving cavity 125 to effectively prevent the locking shaft 310 from being completely pulled out when the user pulls the limiting head 311 upwards; the fixing component 400 is used to fix the limiting head 311, preventing the limiting head 311 from being pulled outwards unintentionally, further improving the locking and fixing performance of the cover plate 200, and ensuring the stability of the fixing mechanism in multiple directions.

[0035] When it is necessary to remove the cover plate 200, the operating fixing assembly 400 releases the axial restriction fixing on the limiting head 311, pulling the limiting head 311 outward to separate it from the limiting cavity 121. Then, rotating the limiting head 311 causes the locking shaft 310 to drive the locking tongue 320 to rotate. The locking tongue 320 rotates back into the rotating cavity 123, releasing the restriction of the locking tongue 320 on the mounting shoulder 210, thus allowing the cover plate 200 to be removed from the mounting opening 110 for maintenance operations. To install the cover plate 200, place the cover plate 200 at the mounting opening 110, rotate the locking shaft 310 to make the locking tongue 320 rotate out until it is above the mounting shoulder 210, and then put the limiting head 311 back into the limiting cavity 121. At this time, the locking tongue 320 presses down on the mounting shoulder 210, thereby locking the cover plate 200 and preventing the cover plate 200 from falling off from the mounting opening 110. At the same time, operate the fixing component 400 to fix the limiting head 311 and prevent the limiting head 311 from accidentally sliding out of the limiting cavity 121.

[0036] Based on the above, in some embodiments, the diameter of the locking shaft 310 is the same as the diameter of the first receiving cavity 122 and the connecting cavity 124, the diameter of the anti-detachment head 312 is larger than the diameter of the locking shaft 310, the first receiving cavity 122 and the connecting cavity 124 are for the locking shaft 310 to rotate, and the anti-detachment head 312 prevents the locking shaft 310 from falling out of the through hole 120.

[0037] Based on the above, in some embodiments, the fixing component 400 includes a fixing pin 410, and a fixing groove 130 is provided on the chassis 100 on one side of the limiting cavity 121. The fixing pin 410 is slidably disposed in the fixing groove 130, and a spring 420 is provided between the end of the fixing pin 410 away from the limiting cavity 121 and the groove wall of the fixing groove 130. A notch 313 is opened on the top surface of the limiting head 311, and the fixing pin 410 extends out of the fixing groove 130 and is located on the notch 313 under the action of the spring. A sliding groove 131 is opened on the upper part of the fixing groove 130, extending to the surface of the chassis 100. A sliding slider 132 is provided in the sliding groove 131, and the bottom of the slider 132 is fixed on the fixing pin 410. In practical use, under the action of spring 420, the fixing pin 410 is positioned above the notch 313 to lock the limiting head 311, preventing it from being pulled out. When it is necessary to pull out the limiting head 311, the user manually moves the slider 132 to move the fixing pin 410 backward until the fixing pin 410 returns from the notch 313 to the fixing groove 130. At this point, the fixing restriction on the limiting head 311 is released, and the user can manually pull out the limiting head. It is worth noting that the notch 313 is designed to facilitate the user's manual removal of the limiting head 311.

[0038] In the above technical solution, a positioning hole 600 is opened on the side wall of the locking shaft 310. The positioning hole 600 matches the shape of the fixing pin 410. With this technical solution, when the limiting head 311 is pulled out and the locking shaft 310 is rotated, the positioning hole 600 corresponds to the fixing pin 410. The user no longer pushes the slider 132. Under the elastic force of the spring 420, the fixing pin 410 extends out of the fixing groove 130 and inserts into the positioning hole 600. On the one hand, the limiting head 311 can be fixed so that the limiting head 311 does not retract into the limiting cavity 121. After the maintenance is completed, the cover plate 200 can be installed without having to pull out the limiting head 311 again. On the other hand, it can be achieved that the user does not need to hold the slider 132 with his hand. After the user operates to release one of the locking components 300 from the cover plate 200, he can operate the other locking component 300. Thus, the user can complete the disassembly and installation operation by himself.

[0039] Preferably, the positioning hole 600 has a clearance portion 610 at one end facing the fixing pin 410. The diameter of the clearance portion 610 gradually decreases from the fixing pin 410 toward the positioning hole 600. The clearance portion 610 facilitates the insertion of the fixing pin 410 into the positioning hole 600.

[0040] Preferably, the slider 132 does not protrude from the surface of the chassis 100. This design avoids the protruding slider 132 from scratching the user and also prevents the slider 132 from sliding unintentionally due to being pulled by external objects.

[0041] Based on the above, in some embodiments, a shielding strip 220 extends outward from the upper surface of the cover plate 200, and the shielding strip 220 can cover the gap between the side wall of the cover plate 200 and the mounting opening 110.

[0042] By employing this utility model, through the cooperation of the locking shaft 310, the locking tongue 320, the limiting head 311, and the limiting cavity 121, it is not necessary to use additional professional tools to tighten or loosen screws to install or remove the cover plate 200. The operation is simple and convenient, improving the efficiency of installation and disassembly, and facilitating the maintenance of internal components of the chassis 100. At the same time, when removing the cover plate 200, the locking component 300 will not be removed from the chassis, and the locking shaft 310 will not be lost.

[0043] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and illustrations shown and described herein. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from the spirit and scope of this utility model.
