Description

Technical Field

[0001] The utility model relates to a computer case accessory, in particular to an anti-slip screwing aid for quick-release screws of a computer case shell plate. Background Art

[0002] The chassis of a desktop computer is used to house and position core components such as the power supply, motherboard, graphics card, hard drive, and provide protection for the above components.

[0003] To facilitate quick disassembly and installation, and thus easier inspection or replacement of core components within the chassis, most existing chassis are quick-release chassis. Specifically, the two side panels of the chassis are fixed to the main chassis body with built-in bayonet pins, and are secured at the rear of the chassis with quick-release screws.

[0004] Quick-release screws can be quickly tightened and removed manually, allowing for the removal and assembly of side panels. Quick-release screws consist of a screw and a plastic shell. The plastic shell wraps around the screw head to facilitate manual tightening.

[0005] Although the plastic shell can be easily screwed by hand to a certain extent, the diameter of the plastic shell is relatively small after all, and the overall shape is cylindrical, and there are no force points on the surface. Therefore, when screwing by hand, it is easy to slip and difficult to screw, which affects the disassembly and assembly experience.

[0006] Existing technology, such as the Chinese utility model patent with publication number "CN206338308U" and titled "A Self-Locking Screw for a Computer Case," discloses the following technical solution: "A self-locking screw for a computer case, comprising a cylindrical plastic screw head and a screw shank. One end face of the screw head is connected to the screw shank and is provided with an anti-slip portion. The center of the other end face of the screw head is provided with a cylindrical hole and a slotted groove. The cylindrical hole is provided with a cross slot. The side of the screw head is provided with an anti-slip groove. The screw shank is provided with a thread with an arc-shaped triangular cross-section. The thread profile angle is 56 degrees, the thread profile angle is 28 degrees, and the thread pitch is 1 mm."

[0007] The above solution uses a large-diameter cylindrical plastic screw head with anti-slip grooves around the periphery to facilitate hand tightening. Although this structure can facilitate hand tightening to a certain extent, the overall cylindrical shape of the cylindrical plastic screw head still lacks a force point for the finger when twisting, resulting in a poor hand tightening experience.

[0012] Furthermore, the inner teeth are specifically located on the inner side of the opening with a larger diameter of the tapered sleeve; the inner teeth are integrally formed with the tapered sleeve and are arranged in a circular array relative to the central axis of the tapered sleeve.

[0013] Furthermore, the anti-slip ring is specifically located on the inner side of the opening with a smaller diameter of the tapered sleeve; the anti-slip ring is annular in shape and is embedded in the annular groove on the inner side of the tapered sleeve.

[0014] Furthermore, the through groove connects the outer side and the inner side of the tapered sleeve; there are two through grooves, which are arranged in a central symmetrical shape with respect to the central axis of the tapered sleeve.

[0015] Furthermore, one end of the connecting piece is connected to the tapered sleeve, and the connecting piece and the tapered sleeve are integrally formed.

[0016] Furthermore, the twisted piece is in sheet shape, and the central axis of the tapered sleeve is located in the plane where the twisted piece is located; the connecting piece and the twisted piece are both arranged in a central symmetrical shape relative to the central axis of the tapered sleeve.

[0017] Furthermore, the strip teeth are specifically located on the side of the connecting piece facing the interior of the tapered sleeve; the strip teeth are specifically strip-shaped convex teeth, and the strip teeth and the connecting piece are integrally formed.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] refer to Figures 1 to 4 A computer case shell quick-release screw anti-slip twisting aid comprises a tapered sleeve 1, an anti-slip ring 3, a connecting piece 5 and a twisting piece 6; wherein, the computer case shell quick-release screw is used to realize the locking and disassembly of the side shell of the computer case; the anti-slip twisting aid is used to be sleeved on the quick-release screw to facilitate human fingers to twist.

[0029] The tapered sleeve 1 is in the shape of a truncated cone sleeve, and both ends of the central axis of the tapered sleeve 1 have openings; it is used to be conveniently sleeved on the plastic shell of the quick-release screw.

[0030] Internal teeth 2 are provided in the tapered sleeve 1, and the internal teeth 2 and the anti-slip ring 3 are respectively located at the two openings of the tapered sleeve 1; the internal teeth 2 are convex teeth-shaped, and are used to engage with the anti-slip grooves of the plastic shell of the quick-release screw to play an anti-slip role; the anti-slip ring 3 is used to play an anti-slip role.

[0031] The connecting piece 5 is located in the through groove 4 on the side wall of the tapered sleeve 1 and is extended along the curvature of the side wall of the tapered sleeve 1 ; the connecting piece 5 is integrally formed with the tapered sleeve 1 and is in sheet shape.

[0032] The screwing piece 6 is located at the end of the connecting piece 5. There are two connecting pieces 5 and two screwing pieces 6. The screwing piece 6 is used to facilitate the finger pinching and tightening action. The presence of the screwing piece 6 helps to increase the tightening torque of the quick release screw and facilitates the finger to exert force.

[0033] The screwing piece 6 is subjected to the twisting force of the finger, and a part of the force can be converted into the pressing force of the connecting piece 5 on the plastic shell of the quick release screw.

[0034] The inner side of the connecting piece 5 is provided with a strip-shaped tooth 7, which is a convex tooth. The strip-shaped tooth 7 is used to engage with the anti-slip groove of the plastic shell of the quick-release screw to play an anti-slip role.

[0035] The inner teeth 2 are specifically located on the inner side of the opening with a larger diameter of the tapered sleeve 1, thereby preventing the plastic shell of the quick-release screw from slipping near one end of the screw.

[0036] The inner teeth 2 are integrally formed with the tapered sleeve 1 and are arranged in a circular array relative to the central axis of the tapered sleeve 1 , matching the anti-slip pattern of the plastic shell of the quick-release screw.

[0037] The anti-slip ring 3 is specifically located inside the opening with a smaller diameter of the tapered sleeve 1. The anti-slip ring 3 is annular and embedded in the annular groove inside the tapered sleeve 1. The anti-slip ring 3 is preferably a rubber ring with good anti-slip performance.

[0038] The through groove 4 connects the outer side and the inner side of the tapered sleeve 1 ; there are two through grooves 4 , and they are arranged in a central symmetrical shape relative to the central axis of the tapered sleeve 1 .

[0039] One end of the connecting piece 5 is connected to the tapered sleeve 1, and the connecting piece 5 and the tapered sleeve 1 are integrally formed. The end of the connecting piece 5, that is, the position of the twisting piece 6, can be slightly deformed when the twisting piece 6 is subjected to force.

[0040] The twisting piece 6 is sheet-shaped, and the central axis of the tapered sleeve 1 is located in the plane where the twisting piece 6 is located, which is convenient for hand twisting; the connecting piece 5 and the twisting piece 6 are arranged in a central symmetrical shape relative to the central axis of the tapered sleeve 1, which is convenient for exerting force when twisting.

[0041] The strip teeth 7 are specifically located on the side of the connecting piece 5 facing the inside of the tapered sleeve 1; the strip teeth 7 are specifically strip-shaped convex teeth, and the strip teeth 7 are integrally formed with the connecting piece 5. The strip teeth 7 are used to be embedded in the anti-slip grooves of the plastic shell of the quick-release screw to achieve an anti-slip effect.

[0042] The twisting piece 6 is provided with anti-skid ribs 8 , which are specifically convex ribs and are oval in shape. The anti-skid ribs 8 are used to enhance the friction between the twisting piece 6 and the fingers.

[0043] The working principle of this utility model is:

[0044] When the side panel of the computer case needs to be removed from the chassis, the quick-release screw needs to be unscrewed from the rear of the chassis. At this time, align the larger diameter opening of the conical sleeve 1 of the anti-slip screwing aid with the plastic shell of the quick-release screw, and then put the conical sleeve 1 on the plastic shell.

[0045] When the cone sleeve 1 is completely put on the plastic shell of the quick release screw, Figure 4 In this state, the inner teeth 2 and the strip teeth 7 are embedded in the anti-slip grooves on the outer surface of the plastic shell of the quick-release screw, thereby achieving embedded anti-slip. At the same time, the anti-slip ring 3 presses the upper side of the plastic shell to achieve tight anti-slip.

[0046] Then, the fingers are pinched on the twisting piece 6 to twist it, and the anti-skid ribs 8 are used to prevent the fingers and the twisting piece 6 from slipping.

[0047] Since the screw piece 6 is located outside the end of the connecting piece 5, the force applied by the finger on the screw piece 6 will increase the pressing force of the connecting piece 5 on the plastic shell of the quick-release screw, so that the strip teeth 7 are tightly embedded in the anti-slip grooves on the outside of the plastic shell, thereby achieving anti-slip with the help of the twisting force of the finger.

[0048] Due to the screwing piece 6 arranged on the outside of the conical sleeve 1, the screwing torque can be increased, which makes it more convenient for the fingers to pinch and screw, facilitates the rapid screwing of the quick-release screw, and realizes the removal or installation and tightening of the quick-release screw, and finally realizes the disassembly or installation of the side shell plate of the computer case.

[0049] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
