Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to anti-slip laptop shell screws. Background Technology

[0002] As an indispensable portable electronic device in modern work and life, laptops integrate highly precise electronic components. To ensure the integrity and stability of the structure, the laptop casing is usually fastened with multiple micro screws.

[0003] During daily use of a laptop, frequent screen opening and closing, movement and carrying, and the operation of internal components such as fans will inevitably generate continuous micro-vibrations and periodic external impacts. These forces will continuously act on the connecting structure of the casing.

[0004] For traditional laptop screws, the tightening force mainly relies on the static friction between the threads. Under long-term continuous vibration and external force, this static friction will be gradually weakened and overcome, causing slight relative slippage between the screw and the screw hole. Over time, the screw will gradually loosen or even fall off.

[0005] Loose screws can cause abnormal noises and structural shaking, reducing the user experience. In severe cases, they can also damage internal circuit boards or other critical components due to insecure fixing, affecting the normal operation and lifespan of the equipment. Existing standard screws lack an active anti-loosening structure that can resist vibration, and therefore cannot fundamentally solve this problem.

[0006] Therefore, this utility model proposes an anti-slip notebook casing screw to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing anti-slip laptop shell screws, which rely solely on thread friction for fixation under long-term vibration and external force, lack an active anti-loosening structure, resulting in easy loosening of the screws and low connection reliability, this utility model aims to provide an anti-slip laptop shell screw with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an anti-slip notebook shell screw, including: a nut, a first rod body fixedly connected to the nut, and a second rod body in a threaded shape disposed at the end of the first rod body away from the nut; and a fastening mechanism.

[0009] The main silicone cover of the fastening mechanism is arranged around the connection area between rod one and rod two.

[0010] The main silicone cover has a fixed cavity inside, and a gel capsule is sealed inside the fixed cavity.

[0011] Furthermore, ventilation holes and connecting holes are provided on the cavity wall of the fixed cavity, and an anti-overflow plate is fixed at the outer opening of the ventilation hole.

[0012] At least one permeation groove is formed on the outer peripheral surface of the rod body 2, and the starting end of the permeation groove is connected to the outlet of the connecting hole.

[0013] Preferably, the anti-slip laptop shell screw also includes a reinforcing mechanism, which is disposed on the nut and is used to solve the problem of easy stripping and wear of the screw during the tightening process.

[0014] Preferably, as a specific implementation of the reinforcing mechanism, it includes a stainless steel lining and a ceramic coating; the stainless steel lining is disposed inside the nut to prevent corrosion, and the ceramic coating covers the outer surface of the nut to improve wear resistance.

[0015] Preferably, the nut has a cross-shaped screw-in groove, and the reinforcing mechanism further includes multiple shallow grooves symmetrically distributed on the main groove wall of the screw-in groove to increase the contact area of ​​the screwdriver.

[0016] Preferably, the reinforcing mechanism further includes a friction pad, which is fixedly disposed on the inner wall of the shallow groove to help prevent slippage by increasing friction.

[0017] Preferably, the reinforcing mechanism further includes a positioning bevel, which is disposed at the opening edge of the shallow groove near the top surface of the nut, for guiding the screwdriver tip to quickly and accurately embed into the groove.

[0018] Preferably, the main silicone cover is made of an elastic deformable material, whose structural characteristics enable it to rupture the gel sac when the rod is screwed in under pressure and deformed.

[0019] Preferably, as a specific layout of the fastening mechanism, the ventilation hole is opened at the top of the fixing cavity, while the connecting hole is opened at the bottom of the fixing cavity. This top-bottom arrangement is conducive to the entry of hot air and the discharge of adhesive.

[0020] Preferably, the number of penetration grooves is four, and the four penetration grooves are evenly distributed at intervals along the axial direction of the second rod on its outer peripheral surface to ensure that the adhesive can be evenly diffused to all parts of the thread.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model integrates a silicone cover, a built-in gel capsule, and a permeation groove on the screw. When the screw is screwed in, the gel capsule is compressed and bursts, releasing strong adhesive that is then fixed through the permeation groove. This solves the problem in the prior art where laptop screws are prone to loosening due to long-term vibration or external force. It achieves the technical effect of automatically locking the screw after it is screwed in and improving the reliability of the connection.

[0023] 2. This utility model solves the problem of difficult disassembly after using adhesive fixing by setting ventilation holes inside the fastening mechanism. When disassembly is required, hot air can be used to soften the cured strong adhesive. This achieves the technical effect of providing strong fixing force while also realizing convenient and reversible disassembly, which greatly facilitates the later maintenance of the equipment.

[0024] 3. This utility model increases the contact area and friction between the screwdriver and the groove by adding a shallow groove, friction pad and positioning bevel inside the screwdriver's turning groove. This solves the problem that traditional Phillips screws are prone to stripping during turning due to small contact area and stress concentration, which leads to damage to the groove. It achieves the technical effect of dispersing torque and effectively preventing stripping, and improves the success rate and convenience of operation. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example:

[0033] Please refer to Figures 1 to 4 This utility model provides anti-slip laptop shell screws, which aim to solve the problems of laptop shell screws being prone to loosening due to vibration, stripping when tightened, and rusting and wear in the prior art.

[0034] like Figure 1 and Figure 2 As shown, the anti-slip laptop shell screw includes a nut 1 and a rod 2 fixedly connected to the nut 1. A second rod 3 is provided at the end of the first rod 2 away from the nut 1. The second rod 3 is threaded. The screw also includes a fastening mechanism 4 located in the connection area between the first rod 2 and the second rod 3. (Refer to...) Figure 3 The main silicone cover 401 of the fastening mechanism 4 is arranged around the connection area between rod 1 2 and rod 2 3. The main silicone cover 401 is made of elastic deformable material and is used to rupture the gel sac 403 when the rod 2 3 is deformed under pressure during screwing. A fixed cavity 402 is opened inside the main silicone cover 401. The gel sac 403 is arranged in the fixed cavity 402. Ventilation holes 405 and connecting holes 404 are opened opposite each other on the cavity wall of the fixed cavity 402. Specifically, the ventilation holes 405 are opened at the top of the fixed cavity 402 and the connecting holes 404 are opened at the bottom of the fixed cavity 402. An anti-overflow plate 406 is fixed at the outer opening of the ventilation holes 405. Four permeation grooves 407 are opened on the outer peripheral surface of rod 2 3. The four permeation grooves 407 are evenly distributed along the axial direction of rod 2 3, and the starting end of each permeation groove 407 is connected to the outlet of the connecting hole 404.

[0035] To solve the problems of easy stripping and wear of screws when tightening the above-mentioned technical issues, the technical solution of this embodiment is that the anti-slip notebook shell screw also includes a reinforcing mechanism 5, and the reinforcing mechanism 5 and the aforementioned nut 1 form an integrated composite structure.

[0036] Please refer to Figure 1 and Figure 4 The structural features of the reinforcing mechanism 5 are reflected in the nut 1. The nut 1 has a stainless steel inner lining 502 inside, and its outer surface is covered with a ceramic coating 501. This composite material structure ensures the rust resistance and wear resistance of the nut 1.

[0037] The top of the nut 1 has a cross-shaped screwing groove. The reinforcing mechanism 5 also includes multiple shallow grooves 503 symmetrically distributed on the main wall of the screwing groove. A friction pad 504 is fixedly installed on the inner wall of the shallow groove 503, and a positioning bevel 505 is provided at the opening edge of the shallow groove 503 near the top surface of the nut 1. This structure, which combines the shallow groove 503, friction pad 504 and positioning bevel 505 in the main screwing groove, greatly increases the contact area and friction between the screwdriver and the nut 1, and provides precise positioning guidance.

[0038] In a preferred embodiment, to further improve the anti-slip properties and durability of the screw, the screw also includes a reinforcing mechanism 5 disposed on the nut 1. The reinforcing mechanism 5 includes a stainless steel inner lining 502 and a ceramic coating 501, wherein the stainless steel inner lining 502 is disposed inside the nut 1, and the ceramic coating 501 covers the outer surface of the nut 1.

[0039] In a further embodiment, the reinforcing mechanism 5 also includes a plurality of shallow grooves 503, which are symmetrically distributed on the main groove wall of the cross-shaped turning groove of the nut 1. A friction pad 504 is fixedly provided on the inner wall of each shallow groove 503, and a positioning bevel 505 is also provided at the opening edge of each shallow groove 503 near the top surface of the nut 1.

[0040] As a preferred limitation of the fastening mechanism 4, the material of the main silicone cover 401 is an elastic deformable material, whose structural characteristics enable it to rupture the gel sac 403 when it is deformed under pressure during the screwing of the rod 2 3.

[0041] As a preferred limitation on the internal structure of the fastening mechanism 4, the ventilation hole 405 is specifically opened at the top of the fixed cavity 402, while the connecting hole 404 is specifically opened at the bottom of the fixed cavity 402. This top-to-bottom arrangement is conducive to the entry of hot air and the outflow of adhesive.

[0042] As a preferred limitation of the structure of rod 2 3, the number of permeation grooves 407 is specifically four, and these four permeation grooves 407 are evenly distributed at intervals along the axial direction of rod 2 3 on its outer peripheral surface.

[0043] Working principle: During laptop use, external forces generated by vibration and screen opening / closing operations can cause screws to gradually loosen. To prevent this, a fastening mechanism 4 is provided. Its main body, a silicone cover 401, is positioned between the two ends of rod 1 2 and rod 2 3. A fixing cavity 402 is formed within the silicone cover 401 to fix the gel capsule 403. Ventilation holes 405 and connecting holes 404 are respectively formed at the top and bottom of the fixing cavity 402. An anti-overflow plate 406 is fixed to the ventilation hole 405. Four penetration grooves 407 are formed on the surface of rod 2 3. When the screws are screwed into the laptop... When the back cover is being tightened, as the rod 2 3 is pushed deeper, the internal space of the back cover gradually touches the silicone cover 401 area. Subsequently, the silicone cover 401 deforms, causing the gel capsule 403 inside to rupture under pressure and release strong adhesive. When the screw is completely screwed to the deepest part of the hole, the strong adhesive flows through the connecting hole 404 and finally overflows into all parts of the screw hole through the penetration groove 407. After standing for a moment, the fixation is completed. When the screw needs to be removed, simply use a hot air blower to gently blow into the ventilation hole 405. The hot air enters the screw through the ventilation hole 405, causing the strong adhesive to melt. Then, it can be removed by unscrewing it in the normal screw operation method.

[0044] Furthermore, in actual operation, when a conventional Phillips head screwdriver is inserted into the slot, the Phillips head provides a basic fit and a certain degree of compatibility, allowing existing screwdrivers to be quickly inserted and avoiding increased operational difficulty due to tool compatibility issues. The four auxiliary contacts play a key role, with shallow grooves 503 symmetrically distributed on the four main slot walls, forming additional contact with the side of the screwdriver tip. The friction pad 504 and the positioning bevel 505 enable the screwdriver to accurately and efficiently position the slot, thereby avoiding the problem of slot stripping caused by excessive stress. The nut 1 has a stainless steel lining 502 to prevent rust, while the surface is designed with a ceramic coating 501 to improve overall wear resistance. The entire reinforcing mechanism 5 achieves compatibility with existing tools, anti-slip, and anti-wear functions, solving the structural defects of traditional screwdriver slots.
