Description

Technical Field

[0001] The utility model relates to the technical field of detachable fixing structures, in particular to a detachable fan bracket assembly. Background Art

[0002] Fans are commonly used in the heat dissipation of mechanical equipment. They are devices that generate air flow to reduce temperature or increase air circulation. They are usually composed of blades, motors, and housings. When a fan is used for a long time, its housing and blades need to be cleaned regularly, and the housing or the fan as a whole needs to be disassembled for cleaning.

[0003] Among the existing patent documents, there is a patent with publication number CN 210087650 U and titled “A detachable bracket fan”. This patent mainly uses the cooperation of bolts and nuts to fix the mounting bracket. When it is necessary to clean the protective shell or repair or replace the entire fan, other tools such as wrenches are required to assist, which makes disassembly inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a detachable fan bracket assembly, which can complete the separate disassembly of the protective shell or the joint disassembly of the fan mounting base and the protective shell by only setting up an elastic positioning assembly, has a lower manufacturing cost, and does not require the assistance of other tools during disassembly, and its disassembly is simple and convenient.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A detachable fan bracket assembly comprises a positioning panel, a fan mounting seat is detachably fixed on the positioning panel, a motor is fixed on the fan mounting seat, a fan blade is connected to the rotating shaft of the motor, a protective shell for wrapping the fan blade is detachably fixed on the fan mounting seat, and the fan mounting seat, the motor, the fan blade and the protective shell together constitute a fan assembly;

[0007] The fan mount and the protective shell are both fixed to the positioning panel through an elastic positioning component. The elastic positioning component includes an outer positioning component fixedly connected to the protective shell, and an inner positioning component fixedly connected to the positioning panel, and the outer positioning component and the inner positioning component are located on the same straight line. The positioning panel, the fan mount and the protective shell can be fixedly connected at the same time through the inner positioning component, and the on / off state of the inner positioning component can be adjusted through the outer positioning component, so as to complete the separate disassembly of the protective shell or the joint disassembly of the fan mount and the protective shell.

[0008] By adopting this solution, an elastic positioning component is provided, which serves as a "switch" for disassembling the fan assembly. The protective shell can be disassembled alone or the fan mounting base and the protective shell can be disassembled together by only providing one place. The manufacturing cost is lower, and no other tools are required during disassembly. The disassembly is simple and convenient. By disassembling the protective shell at a single place, it is convenient to maintain and clean the fan blades. By disassembling the fan mounting base and the protective shell together, it is convenient to replace or repair the entire fan assembly.

[0009] As a preferred embodiment of a detachable fan bracket assembly, the external positioning assembly includes a reference seat fixedly connected to the protective shell, the reference seat is movably connected with an external plug, the external plug can penetrate and connect the fan mounting seat and the protective shell, and the pin body of the external plug is sleeved with a spring to push it to move toward the location of the protective shell;

[0010] The inner positioning assembly includes an inner pin, which can penetrate and connect the positioning panel, the fan mounting seat, and the protective shell, and the inner pin and the outer pin are located on the same straight line. The inner pin is slidably connected to the guide shaft, and the guide shaft is sleeved with a spring 2 that pushes the inner pin to move toward the location of the positioning panel;

[0011] The elasticity of the second spring is greater than that of the first spring, and the inner plug can push the outer plug out of the protective shell under the elastic action of the second spring.

[0012] With this solution, when in use, the outer positioning component and the inner positioning component are used together, and the inner pin can push the outer pin out of the protective shell under the elastic action of spring 2. At this time, the fan mounting seat and the protective shell are firmly fixed on the positioning panel. When disassembly is required, press the outer pin by hand, and the inner pin can be pushed out of the fan mounting seat or the protective shell through the outer pin, and the corresponding disassembly can be easily completed.

[0013] As a preferred embodiment of a detachable fan bracket assembly, a guide seat is also fixed on the protective shell, the outer plug passes through the guide seat, a guide block is fixedly connected to the pin body of the outer plug, a guide slot 1 and a guide slot 2 are provided in the guide seat, and the guide block can slide along the guide slot 1 or the guide slot 2;

[0014] The slot length of the second guide chute is greater than the slot length of the first guide chute;

[0015] The position of the first guide slot and the position of the second guide slot are symmetrically distributed about the center of the guide seat.

[0016] By adopting this solution, in order to ensure that the distance of movement of the outer pin is controlled more accurately when the outer pin is pressed, a guide slide groove 1 and a guide slide groove 2 are provided; when the outer pin is pushed until the guide block slides to the end of the guide slide groove 1, the outer pin just pushes the inner pin to the junction of the protective shell and the fan mounting seat, and the protective shell can be removed at this time, which is convenient for maintenance and cleaning of the fan blades; when the outer pin is pushed until the guide block slides to the end of the guide slide groove 2, the outer pin just pushes the inner pin to the junction of the fan mounting seat and the positioning panel, and the fan mounting seat and the protective shell can be removed at the same time, which is convenient for replacement or repair of the entire fan assembly.

[0017] As a preferred embodiment of a detachable fan bracket assembly, the diameter of the outer pin is equal to the diameter of the inner pin.

[0018] This solution is adopted to ensure that the fan mount and the protective shell will not scatter and separate when they are removed at the same time. When the outer pin pushes out the inner pin, the outer pin can still achieve a through connection between the fan mount and the protective shell under the elastic action of spring 1. Therefore, the fan mount and the protective shell will not scatter and separate after disassembly.

[0019] After adopting the above technical solution, the beneficial effects of the utility model are:

[0020] 1. By setting an elastic positioning component, which serves as a "switch" for disassembling the fan assembly, the protective shell can be disassembled alone or the fan mounting base and the protective shell can be disassembled together by setting only one place, the manufacturing cost is lower, and no other tools are required during disassembly, and the disassembly is simple and convenient; by disassembling the protective shell at a single place, it is convenient to maintain and clean the fan blades; by disassembling the fan mounting base and the protective shell together, it is convenient to replace or repair the entire fan assembly.
