Description

Technical Field

[0001] The utility model relates to the field of fans, in particular to a fan structure which is easy to assemble and disassemble. Background Art

[0002] Fans are generally used to generate airflow to improve gas circulation efficiency and are often used in ventilation, equipment heat dissipation and other fields.

[0003] In the prior art, fans need to be replaced after performance degradation or damage. Generally, the mechanical, electrical, and fixed connections to the device to which the fan device is fixed must be released, and then the electrical and mechanical connections of the fan within the device must be released. The fan device must then be replaced, and the above operation process must be repeated in reverse. When a large number of fans need to be replaced, the normal operation of the device can be easily affected, increasing the maintenance cost and the procedures required for maintenance.

[0004] In summary, the existing fan replacement process is lengthy and difficult to achieve convenient replacement. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a fan structure that is easy to disassemble and assemble, so as to solve the technical problem that the existing fan is difficult to replace.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a fan structure that is easy to disassemble and assemble, comprising a mounting seat, a ventilation hole is provided in the center of the mounting seat, an outer frame is connected to the mounting seat by a self-locking connection structure, a fan is installed in the outer frame, and conductive contacts that are in contact with each other are provided between the outer frame and the mounting seat.

[0007] By adopting the above technical solution, after the connection structure fixes the mounting base in the desired fixed position, the outer frame equipped with the fan is quickly connected to the mounting base through the self-locking plug-in structure. The conductive contacts between the outer frame and the mounting base contact each other to energize the fan. When the fan needs to be disassembled, it is only necessary to release the self-locking state between the mounting base and the outer frame to make the fan pop out, which greatly simplifies the disassembly and assembly steps of the fan and effectively improves the disassembly and assembly efficiency of the fan.

[0008] The present invention is further configured such that at least one self-locking socket is fixedly connected to the mounting seat in a direction toward the outer frame, and a self-locking plug column for cooperating with the self-locking socket is fixedly connected to the outer frame.

[0009] By adopting the above technical solution, the number and setting positions of the self-locking sockets and self-locking pins can be adaptively changed according to different fan sizes and shapes. The self-locking sockets and self-locking pins can be self-locked when relatively plugged in, and the self-locking can be released by simply pressing when disassembling.

[0010] The present invention is further configured such that at least one socket is provided at one end of the mounting seat away from the self-locking socket, and an inserting strip for cooperating with the socket is fixedly connected to the outer frame.

[0011] By adopting the above technical solution, providing the insertion hole and the insertion strip structure between the mounting seat and the outer frame can save the manufacturing cost of the fan while achieving the self-locking connection function.

[0012] The present invention is further configured such that at least one first magnetic sheet is fixedly connected to the mounting base in a direction toward the outer frame, and a second magnetic sheet for cooperating with the first magnetic sheet is fixedly connected to the outer frame.

[0013] By adopting the above technical solution, the number and setting position of the first magnetic sheet and the second magnetic sheet can be adaptively changed according to different fan sizes and shapes. The first magnetic sheet and the second magnetic sheet can attract each other to complete self-locking when relatively plugged in. When disassembling, you only need to pull out the outer frame in reverse to complete the self-locking.

[0014] The present invention is further configured such that at least one socket is provided at one end of the mounting base away from the first magnetic sheet, and an inserting strip for cooperating with the socket is fixedly connected to the outer frame.

[0015] By adopting the above technical solution, providing the insertion hole and the insertion strip structure between the mounting seat and the outer frame can save the manufacturing cost of the fan while achieving the self-locking connection function.

[0016] The present invention is further configured such that at least one self-locking spring is fixedly connected to the outer frame, a snap-in groove for cooperating with the self-locking spring is provided on the inner wall of the mounting seat, at least one socket is provided at one end of the mounting seat away from the snap-in groove, and an insert strip for cooperating with the socket is fixedly connected to the outer frame.

[0017] By adopting the above technical solution, the outer frame and the mounting base can be easily unlocked by pressing the self-locking spring.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The utility model fixes the mounting base in a desired fixed position through the connection structure, and the outer frame equipped with the fan is quickly connected to the mounting base through the self-locking connection structure. The conductive contacts between the outer frame and the mounting base contact each other to energize the fan. When the fan needs to be disassembled, it is only necessary to release the self-locking state between the mounting base and the outer frame to make the fan pop out, which greatly simplifies the disassembly and assembly steps of the fan and effectively improves the disassembly and assembly efficiency of the fan.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The following describes an embodiment of the present invention based on its overall structure.

[0041] Example 1

[0042] A fan structure that is easy to disassemble and assemble, such as Figure 1-4 As shown, it includes a mounting base 1, which is installed on a mounting wall 4. The mounting wall 4 is provided with a mounting hole 5 for matching the mounting base 1. Specifically, the mounting base 1 is fixedly connected to the mounting wall 4 through a fixing structure. Specifically, the fixing structure adopts screws 6, and can also adopt fixing methods such as bolts, glue, and magnetism. In actual use, the mounting wall 4 can be a chassis wall or a wall, etc. A vent is provided in the center of the mounting base 1, and the mounting base 1 is connected to the outer frame 2 by a self-locking connection structure. Specifically, the self-locking connection structure includes a self-locking buckle structure, and can also adopt a magnetic connection method, for example. , a fan 3 is installed in the outer frame 2, and the outer frame 2 and the fan 3 are an integrated structure. Conductive contacts that are in contact with each other are provided between the outer frame 2 and the mounting base 1. Specifically, in this embodiment, a contact pin 10 is provided on the mounting base 1, and a contact socket 9 corresponding to the contact pin 10 is provided on the outer frame 2. The number of the contact pin 10 and the contact socket 9 is at least two. Some fans 3 include RGB or ARGB lighting effects. In order to enable the lights on the fan 3 to be electrically connected to the mounting base 1, the contact pin 10 and the contact socket 9 between the mounting base 1 and the fan 3 are also increased.

[0043] See also Figure 3-4, the mounting base 1 is fixedly connected with four self-locking sockets 8 in the direction of the outer frame 2, and the outer frame 2 is fixedly connected with a self-locking pin 7 in the direction of the self-locking pin 8. Specifically, the self-locking pin 7 and the self-locking pin 8 are structures of the prior art that press the self-locking buckle. The mounting base 1 is also provided with a contact pin 10 in the direction of the outer frame 2, and the outer frame 2 is provided with a contact socket 9 for cooperating with the contact pin 10 in the direction of the contact pin 10. Specifically, when the self-locking pin 7 is connected to the self-locking pin 8, the mounting base 1 and the outer frame 2 are in a state of being locked. The fan 3 on the outer frame is electrically connected to the contact socket 9 through the contact pin 10. When replacing the fan 3, you only need to press the outer frame 2 to separate the self-locking pin 7 from the self-locking socket 8, and then you can easily remove the outer frame 2, and then align the outer frame 2 with the new fan 3 with the mounting base 1 and insert it. Specifically, the self-locking pin 7 and the self-locking socket 8 can be adaptively adjusted according to the shapes of the outer frame 2 and the mounting base 1. Three sets of self-locking pins 7 and self-locking sockets 8 are used on the circular mounting base 1 and the outer frame 2 to ensure a stable connection between the mounting base 1 and the outer frame 2.

[0044] Example 2

[0045] A fan structure that is easy to disassemble and assemble, such as Figure 5-6 As shown, based on the embodiment 1, the difference from the embodiment 1 is that two self-locking sockets 8 are fixedly connected to the upper side of the mounting base 1 toward the direction of the outer frame 2, and a self-locking pin 7 is fixedly connected to the outer frame 2 toward the direction of the self-locking socket 8. Two sockets 11 are provided at the bottom of the mounting base 1, and the bottom end of the outer frame 2 is fixedly connected to an insertion strip 12 for inserting into the socket 11. When connecting the mounting base 1 and the outer frame 2, first tilt the outer frame 2 so that the insertion strip 12 is aligned with the direction of the socket 11 and inserted, and at the same time, when rotating the outer frame 2 to make it lean against the mounting base 1, the self-locking pin 7 is aligned with the direction of the self-locking socket 8 and inserted. The fan installation work can be completed conveniently with only one hand. When disassembling the fan, press the upper part of the outer frame 2 to separate the self-locking pin 7 from the self-locking socket 8, and then directly take out the outer frame 2 diagonally upward.

The poles of adjacent second magnetic sheets 14 on the outer frame 2 are different, and the poles of the diagonal second magnetic sheets 14 are the same. The connection method between the outer frame 2 and the mounting base 1 is magnetic connection. When in the outer frame 2, due to the magnetic anti-mistake design of the magnet between the mounting base 1 and the outer frame 2, the outer frame 2 and the mounting base 1 can be quickly connected only when the installation direction of the outer frame 2 is correct, avoiding the phenomenon of reverse installation of the outer frame 2.

Two insertion holes 11 are provided at the bottom of the mounting base 1, and an insertion strip 12 for inserting into the insertion hole 11 is fixedly connected to the bottom end of the outer frame 2. When connecting the mounting base 1 and the outer frame 2, the outer frame 2 is first tilted so that the insertion strip 12 is aligned with the direction of the insertion hole 11 and inserted.

[0055] A fan structure that is easy to disassemble and assemble, such as Figure 13-14 As shown, based on the fourth embodiment, the difference from the second embodiment is that a first magnetic sheet 13 is fixedly connected to the upper side of the mounting base 1 toward the outer frame 2, and a second magnetic sheet 14 is fixedly connected to the outer frame 2 toward the first magnetic sheet 13. Specifically, the first magnetic sheet 13 is arranged at the center position of the upper part of the outer frame 2. On the premise of achieving a stable connection between the outer frame 2 and the mounting base 1, the manufacturing cost of the fan is saved.

[0056] Example 8

[0057] A fan structure that is easy to disassemble and assemble, such as Figure 15-16 As shown, on the basis of Example 1, the difference from Example 1 is that the present invention is further configured as follows: two self-locking spring clips 16 are fixedly connected to the outer frame 2, and a snap-in groove 17 is provided on the inner wall of the mounting seat 1 for cooperating with the self-locking spring clip 16.

The self-locking spring clip 16 is deformed until it is matched with the snap-in groove 17, and the installation of the outer frame 2 is quickly realized. The two self-locking spring clips 16 can ensure the stable connection between the outer frame 2 and the mounting seat 1.

[0058] Example 9

[0059] A fan structure that is easy to disassemble and assemble, such as Figure 17-18 As shown, based on the eighth embodiment, the difference from the eighth embodiment is that the present invention is further configured such that a self-locking spring piece 16 is fixedly connected to the outer frame 2, and the inner wall of the mounting seat 1 is provided with a snap-in groove 17 for cooperating with the self-locking spring piece 16. When the volume of the outer frame 2 is small, a self-locking spring piece 16 can also achieve a firm connection between the mounting seat 1 and the outer frame 2, and the outer frame 2 can be disassembled with one hand, which further improves the convenience of disassembling the outer frame 2.

[0060] The working principle of the present invention is as follows: when the fan 3 needs to be replaced, the self-locking connection between the mounting base 1 and the outer frame 2 is released, the outer frame 2 equipped with the new fan 3 is replaced, and the outer frame 2 is aligned with the mounting base 1, so that the self-locking structure between the mounting base 1 and the outer frame 2 completes self-locking, and the conductive contacts between the outer frame 2 and the mounting base 1 complete electrical connection at the same time, so that the fan 3 can be replaced quickly and conveniently.
