[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides a rotatable CPU water block quick-release fastener structure, including a water block body 1, a fastener bracket 2 and a rotation positioning component 3. The fastener bracket 2 is connected to the water block body 1 through a rotating sleeve 11, and the rotating sleeve 11 is coaxially arranged with the water block body 1, so that the fastener bracket 2 can rotate around the axis of the water block body 1.

[0027] The fastener bracket 2 is symmetrically provided with quick-release buckles 21 on both sides. Each quick-release buckle 21 includes an elastic locking arm 22. One end of the elastic locking arm 22 is fixedly connected to the fastener bracket 2, and the other end is provided with a limiting boss 24.

[0028] The symmetrical quick-release clips 21 on both sides use elastic clip arms 22 made of spring steel, with an angle of 120-150° between them and the clip bracket 2. When the elastic clip arms 22 are engaged in the mainboard mounting holes, the anti-slip texture 23 at the free end generates frictional resistance against the hole wall, while the limiting protrusion 24 prevents the clips from completely disengaging. Disassembly is achieved by simply pressing the middle section of the elastic clip arms 22, causing them to deform and disengage from the mounting holes, utilizing the high elasticity and restoring force of the spring steel for quick unlocking.

[0029] The rotary positioning component 3 includes a positioning toothed ring 31 and a positioning block 32. The positioning toothed ring 31 is fixedly sleeved on the rotary sleeve 11, and the positioning block 32 is disposed on the water cooling head body 1 and engages with the tooth groove of the positioning toothed ring 31.

[0030] The fastener bracket 2 is coaxially connected to the water-cooling head body 1 via a stepped shaft rotating sleeve 11. The large-diameter section of the rotating sleeve 11 is fixed to the water-cooling head body 1, while the small-diameter section passes through the fastener bracket 2 and is locked by a nut, forming a stable rotation fulcrum. The positioning toothed ring 31 is fixed on the rotating sleeve 11, and its equally spaced V-shaped toothed grooves on its outer circumference cooperate with the V-shaped positioning blocks 32 on the water-cooling head body 1. When the fastener bracket 2 rotates, the positioning blocks 32 are engaged in different toothed grooves under the action of a compression spring, achieving ±15° step angle locking. This design restricts the degree of rotational freedom through mechanical engagement, ensuring that the installation angle accuracy error is less than ±2°.

[0031] Furthermore, the rotating sleeve 11 has a stepped shaft structure, comprising a large-diameter section and a small-diameter section. The large-diameter section is fixedly connected to the water-cooling head body 1, and the small-diameter section passes through the fastener bracket 2 and is locked with a nut. Compared to traditional screw fixing methods, single-handed operation is achieved through rotational positioning and elastic clips, significantly reducing installation time. Its multi-platform compatibility allows it to adapt to different CPU socket spacings without changing the fastener.

[0032] Furthermore, the elastic retaining arm 22 is made of spring steel, and the free end of the elastic retaining arm 22 is provided with anti-slip texture 23. The natural frequency (approximately 80Hz) of the spring steel elastic retaining arm 22 avoids the main vibration frequency band (30-60Hz) of the CPU fan. When the installation pressure exceeds the tolerance limit of the CPU surface, the elastic retaining arm 22 will undergo plastic deformation rather than break, thus avoiding hardware damage.

[0033] Furthermore, the toothed grooves are V-shaped grooves with equal spacing, and the positioning block 32 is a V-shaped block that matches the toothed grooves. The positioning block 32 is connected to the water-cooling head body 1 via a compression spring. The combination design of the stepped shaft rotating sleeve 11 and the nut locking, while ensuring rotational flexibility, eliminates axial movement through mechanical limiting, thereby improving the torsional stiffness of the overall structure.

[0034] Furthermore, a buffer pad 13 is provided at the bottom of the fastener bracket 2. The buffer pad 13 is made of silicone and has a thickness of 1-3mm. The silicone buffer pad 13, in conjunction with the overall vibration, significantly reduces vibration.

[0035] Furthermore, the water-cooling head body 1 is provided with a rotation angle mark, and the fastener bracket 2 is provided with a corresponding angle indicator line. The scale line on the water-cooling head body 1 and the indicator line on the fastener bracket 2 form a visual angle reference. With the clearance fit between the auxiliary positioning post 12 and the positioning hole (tolerance ±0.05mm), the installation angle deviation can be controlled within ±5°. The 1-3mm silicone buffer pad 13 at the bottom of the fastener bracket 2 absorbs installation stress through the viscoelasticity of the material, while the O-ring seal 14 forms a double seal between the rotating sleeve 11 and the water-cooling head body 1.

[0036] Furthermore, a sealing ring 14 is provided between the rotating sleeve 11 and the water-cooling head body 1. The sealing ring 14 is an O-ring rubber ring. The O-ring sealing ring 14 is made of fluororubber, which maintains elasticity in a temperature range of -40℃ to 120℃. Combined with the precision machining of the rotating sleeve 11, it has strong sealing performance.

[0037] Furthermore, auxiliary positioning posts 12 are provided on both sides of the fastener bracket 2, and corresponding positioning holes are provided on the water cooling head body 1. The auxiliary positioning posts 12 are fitted with the positioning holes with a clearance fit. Each component can be replaced individually; for example, the replacement cost of the elastic clip arm 22 is low. Disassembly can be completed without special tools, making it convenient for users to regularly clean the thermal grease residue at the bottom of the cooling head.

[0038] To further clarify, the angle between the elastic arm 22 of the quick-release buckle 21 and the buckle bracket 2 is 120-150 degrees.

[0039] In summary, the quick-release clip 21 uses a spring steel elastic arm 22 with a 120-150° angle, combined with a limiting boss 24 and anti-slip texture 23, allowing for tool-free one-handed operation, significantly reducing installation time and combining convenience with durability. The rotary positioning component 3, through the step-by-step engagement of the V-shaped groove and the locking block, combined with angle markings and auxiliary positioning posts 12, ensures low installation angle error, adapts to different CPU socket spacings, and improves multi-platform compatibility. The stepped shaft rotating sleeve 11 eliminates axial movement and enhances torsional rigidity; the silicone buffer pad 13 and the spring steel locking arm avoid the fan vibration frequency band, reducing overall vibration; the fluororubber O-ring seal 14 maintains elasticity from -40℃ to 120℃, ensuring reliable sealing. The modular design of each component allows for individual replacement, reducing maintenance costs and facilitating the cleaning of residual thermal grease from the cold head, comprehensively improving the user experience and heat dissipation stability.
