[0035] Reference Figures 1-7 This utility model provides an embodiment of a fan head disassembly and assembly structure, comprising:

[0036] Support arm 1, bearing sleeve 2, support arm cover 3, pressing part 4, pin header 5 and pin header seat 6;

[0037] The outer wall of the bearing sleeve 2 is provided with a groove 21;

[0038] The pressing element 4 is provided with a hook that matches the groove 21;

[0039] The end of the support arm 1 has a sleeve, which is fitted onto the outer wall of the bearing sleeve 2;

[0040] The pressing member 4 is movably mounted on the support arm cover 3, and its hook portion forms a detachable snap-fit ​​engagement with the groove 21 of the bearing sleeve 2.

[0041] The pin header 5 is fixedly installed inside the support arm 1, and the pin header seat 6 is set on the bearing sleeve 2. The pin header 5 and the pin header seat 6 are matched and plugged in for fan power supply.

[0042] It should be noted that the fan head disassembly and assembly structure includes an arm 1, a bearing sleeve 2, an arm cover 3, a pressing component 4, pin headers 5, and a pin header seat 6. The outer wall of the bearing sleeve 2 has a groove 21, and the pressing component 4 has a hook that matches the groove 21. The end of the arm 1 is sleeved onto the outer wall of the bearing sleeve 2, and the pressing component 4 is movably mounted on the arm cover 3, with its hook and groove 21 forming a detachable snap-fit ​​engagement. This snap-fit ​​design between the hook and groove 21 allows for quick disassembly and assembly of the arm 1 and bearing sleeve 2 without tools, significantly improving disassembly efficiency. The pin headers 5 are fixedly installed inside the arm 1, and the pin header seat 6 is located on the bearing sleeve 2; the two are matched and plugged in to provide power to the fan.

[0043] In some embodiments, the arm cover 3 covers the open end on one side of the arm 1 and is snapped in place.

[0044] It should be noted that the arm cover 3 covers the open end of one side of the arm 1 and is fixed by a snap-fit ​​mechanism. The snap-fit ​​design makes it more convenient to use and easier to install and remove.

[0045] In one example, the pin header 6 is embedded inside the bearing sleeve 2, and the contact of the pin header 5 at the end away from the pin header 6 is connected to the power supply line of the fan head.

[0046] It should be noted that the pin header 6 is embedded inside the bearing sleeve 2, and the contacts of the pin header 5 are directly connected to the fan power supply line, reducing the number of intermediate wires, improving the reliability of the electrical connection, and reducing contact resistance.

[0047] The pressing head on the pressing member 4 extends to the outer wall of the support arm cover 3. When the pressing member 4 is pressed, its hook will disengage from the groove 21 of the bearing sleeve 2, separating the support arm 1 from the bearing sleeve 2.

[0048] It should be noted that the pressing head of the pressing component 4 extends to the outer wall of the support arm cover 3, making it convenient for users to apply force directly. When the pressing component 4 is pressed, the hook part disengages from the groove 21, and the support arm 1 separates from the bearing sleeve 2, further simplifying the disassembly process and reducing the difficulty of operation for users.

[0049] The inner wall of the sleeve at the end of the support arm 1 is clearance-fitted with the outer wall of the bearing sleeve 2, and the axial length of the sleeve is greater than the length of the engagement area of ​​the bearing sleeve 2.

[0050] It should be noted that the inner wall of the sleeve at the end of the support arm 1 and the outer wall of the bearing sleeve 2 are in clearance fit, and the axial length of the sleeve is greater than the length of the engagement area of ​​the bearing sleeve 2. The clearance fit allows for slight displacement of the sleeve in the axial direction, avoiding jamming problems caused by assembly errors or thermal expansion; at the same time, the sleeve length design ensures the stability of the engagement area and prevents accidental detachment.

[0051] The pin header 5 is an elastic conductive metal sheet, and its free end forms an elastic contact with the pin header seat 6.

[0052] It should be noted that the pin header 5 adopts an elastic conductive metal sheet design, with its free end forming an elastic contact with the pin header base 6, ensuring contact stability during long-term use and avoiding the risk of power failure due to vibration or temperature changes.

[0053] In practical applications, quick assembly / disassembly and stable power supply are achieved through the engagement of hooks and slots 21, unlocking by pressing, and elastic conductive contact. During installation, the user first inserts the bearing sleeve 2 into the sleeve at the end of the support arm 1. The clearance fit between the inner wall of the sleeve and the outer wall of the bearing sleeve 2 allows for axial fine adjustment, preventing jamming due to assembly errors or thermal expansion. At this time, the hook of the pressing component 4 aligns with the slot 21 on the outer wall of the bearing sleeve 2. After pushing the pressing component 4 to reset, the hook engages in the slot 21 to form a mechanical fixation, completing the connection between the support arm 1 and the bearing sleeve 2. Simultaneously, the pin header 5 adopts an elastic conductive metal sheet design that moves with the support arm 1. Its free end automatically engages with the pin header seat 6 embedded in the bearing sleeve 2. The elastic contact ensures the reliability of the electrical connection and supplies power to the fan. During disassembly, the user presses the pressing head on the outer wall of the support arm cover 3, driving the pressing component 4 to move inward, causing the hook to disengage from the slot 21 and releasing the mechanical lock. At this time, the support arm 1 separates from the bearing sleeve 2, and the fan head can be easily removed. The flexible design of pin 5 further compensates for minor displacements that may occur during disassembly and assembly, ensuring continuous power supply. This structure can be operated without tools, and the intuitive press-to-unlock design significantly reduces the difficulty of operation for users. At the same time, through multi-point locking and flexible redundancy design, it solves the problems of easy loosening and poor contact in traditional fan disassembly and assembly structures.

[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
