[0049] The prior art discloses a threaded connection method using a chassis knob, which does not require tools, but is still not convenient enough. After inserting the column into the chassis, the chassis must be turned over and the chassis knob must be tightened.

[0050] The prior art discloses a method of connecting the chassis column through a threaded screw hole, which can be installed and removed without turning over the chassis or using tools. However, in order to ensure the connection stability, the thread pitch is usually designed to be relatively small, thereby increasing the number of meshing circles, and the operation is time-consuming and not fast enough.

[0051] The prior art discloses a screw-on connection method, which does not require flipping the chassis or using tools, saving time and effort. However, this method requires alignment during installation, and the chassis needs to be fixed by foot or other means during rotational installation, which is inconvenient to operate. It is only connected by 4 screws, and long-term disassembly and assembly may cause wear and failure.

[0052] It can be seen that the installation and disassembly process of the connection between the column and the chassis in the prior art is complicated, which not only affects the user experience, but also increases unnecessary time and labor costs.

[0053] The purpose of this application is to provide a support structure to solve the problem that the connection method between the column and the chassis of the floor-standing fan in the prior art leads to a relatively complicated installation and disassembly process of the column and the chassis, such as Figures 1 to 8 As shown, the support structure provided by the present application includes a column and a chassis, and a disassembly hole is provided on the chassis.

The locking component 4 comprises a locking surface 5 matched with the axial limiting surface 3. The locking component 4 is movably arranged so that when the plug connector assembly is inserted into the disassembly hole, the axial limiting surface 3 and the locking surface 5 gradually approach each other until they are in limiting contact with each other, so that the plug connector assembly is limited in the assembly position.

[0056] The unlocking component 6 is installed on the plug connector assembly in an adjustable position along the plugging direction of the plug connector assembly; the unlocking component 6 cooperates with the locking component 4 so that when the plug connector assembly continues to move along its plugging direction from the assembly position, the unlocking component 6 pushes the locking component 4 to move so that the locking surface 5 is out of contact with the axial limit surface 3, and when the plug connector assembly is pulled out of the disassembly hole, the unlocking component 6 blocks the axial limit surface 3 to avoid the axial limit surface 3 from being in limiting contact with the locking surface 5.

Compared with the prior art, screws and nuts are not required, thereby avoiding the problem of screw and nut loss. The support structure provided by the present application is more convenient during installation and disassembly, and does not require redundant components. In addition, during installation, there is no need to reverse the chassis 2. Only the chassis 2 needs to be placed on the ground, the plug connector assembly needs to be aligned with the disassembly hole on the chassis 2, and a force needs to be applied downward to achieve installation of the two. This avoids the problem that the chassis 2 is too heavy and difficult to rotate during installation, and the chassis 2 may fall to the ground and be damaged during installation. At the same time, the support structure designed in the present application does not need to be rotated during installation, and there is no problem of more or less engagement circles.

Figure 3 As shown, the other end of the second column 18 can be inserted into the avoidance groove 21, and an annular groove is provided at the end of the second column 18 away from the first column 17. The plug connector assembly also includes a support spring 22, one end of the support spring 22 is provided in the annular groove, and the other end of the support spring 22 can abut against the avoidance groove 21. During the downward movement of the plug connector assembly, the support spring will be compressed. During the upward movement, due to the reaction force of the support spring 22, the support spring 22 will push the second column 18 to move away from the avoidance groove 21, and the second column 18 will also push the first column 17 away from the avoidance groove. The unlocking elastic member 16 is a spring in the present embodiment, and the unlocking elastic member 16 can be sleeved on the second column 18. A limiting groove 23 is provided on one end of the unlocking member 6 which is relatively close to the axial limiting surface 3. One end of the unlocking elastic member 16 is inserted into the limiting groove 23, and the other end is connected to or abuts against the axial limiting surface 3 to guide the upward or downward movement of the second column 18. At the same time, the unlocking elastic member 16 can be prevented from bending during the compression process to ensure that the plug connector assembly can normally enter and exit the disassembly hole.

[0083] Furthermore, the plug connector assembly has an installation guide surface 24, which is located below the axial limit surface 3 and is inclined to the axial limit surface 3, so that when the plug connector assembly is inserted into the disassembly hole, the installation guide surface 24 guides the locking component 4 to move the locking surface 5 to the top of the axial limit surface 3.

[0084] Specifically, Figure 4As shown, the plug connector assembly also has an installation guide surface 24, which is below the axial limit surface 3 and is inclined. The plane formed by the installation guide surface 24 is a third plane, and the angle formed between the third plane and the horizontal plane is a first preset angle. The range of the first preset angle is between 110° and 120°, that is, the surface formed by the third plane around the axis of the column 1 is conical, and the large-diameter end of the surface is arranged toward the column 1, which can be beneficial to the installation and disassembly of the plug connector assembly and can achieve that when the plug connector assembly is inserted into the disassembly hole, the installation guide surface 24 can guide the locking component 4 so that the locking surface 5 moves to above the axial limit surface 3.

[0085] Furthermore, the locking component 4 has a pushing surface 25, which is located above the locking surface 5, so that when the plug connector assembly is inserted into the disassembly hole, the installation guide surface 24 cooperates with the locking surface 5 to push the locking component 4 to move in the direction away from the plug connector assembly; or when the plug connector assembly continues to move along its insertion direction from the assembly position, the unlocking component 6 cooperates with the installation guide surface 24 to push the locking component 4 to move in the direction away from the plug connector assembly.

[0086] Specifically, Figure 8 As shown, the locking component 4 has a pushing surface 25, and the pushing surface 25 is above the locking surface 5. The shape of the pushing surface 25 formed around the axis of the column 1 is a frustum, and its large-diameter end is relatively far away from the axial limit surface 3. When the plug connector assembly is inserted into the disassembly hole, the installation guide surface 24 can cooperate with the locking surface 5 to push the locking component 4 to move in the direction away from the plug connector assembly, or when the plug connector assembly continues to move along its insertion direction from the assembly position, the unlocking component 6 can cooperate with the installation guide surface 24 to push the locking component 4 to move in the direction away from the plug connector assembly.

[0087] Furthermore, a disassembly guide surface 26 is provided on the unlocking component 6, and the disassembly guide surface 26 is located on the outer peripheral surface of the unlocking component 6, so that when the plug connector assembly is pulled out from the disassembly hole, the locking component 4 contacts with the disassembly guide surface 26 and moves along the disassembly guide surface 26 to avoid the locking surface 5 from being in limiting contact with the axial limiting surface 3.

[0088] Specifically, Figure 7 As shown, a disassembly guide surface 26 is provided on the unlocking component 6. The shape of the disassembly guide surface 26 formed by surrounding the axial direction of the column 1 is a frustum, and its large-diameter end is arranged toward the axial limit surface 3. The disassembly guide surface 26 is the outer peripheral surface of the unlocking component 6, which can achieve that when the plug connector assembly is pulled out of the disassembly hole, the locking component 4 can contact with the disassembly guide surface 26 and move along the disassembly guide surface 26 to avoid the locking surface 5 from contacting the axial limit surface 3. The plane where the large-diameter end of the unlocking component 6 is located is the first abutment surface 27.

[0089] The present application also provides a fan, which has the above supporting structure.

[0090] The present application also provides a fan, on which a supporting structure as described in the above embodiment is provided.

[0091] Working principle: During use, a downward force is applied to the column 1, and the column 1 will transfer the force to the plug connector assembly, and the plug connector assembly will move downward. During the downward movement, the installation guide surface 24 will first contact the pushing surface 25 and continue to move downward. Under the action of the installation guide surface 24, the locking component 4 will push the locking sleeve 9 to move away from the plug connector assembly. During the movement, the locking elastic member 8 will be compressed to provide space for the plug connector assembly to move downward. When the height of the locking surface 5 is staggered with the height of the axial limit surface 3, the thrust of the installation guide surface 24 on the locking surface 5 disappears, and the locking surface 5 will contact the installation guide surface 24. The unlocking component 6 moves away from the plug connector assembly under the action of the unlocking elastic member 16. The locking member 4 is in the fixed space, and the column 1 is fixed inside the chassis 2, that is, the plug connector assembly is restricted to the assembly position, and the column 1 cannot be pulled out, and the assembly of the chassis 2 and the column 1 is completed. When the column 1 needs to be removed from the disassembly hole, the downward force is continued to be applied to the column 1. Under the action of the limiting end face 19, the unlocking member 6 will move downward, and the unlocking elastic member 16 will be compressed under the action of the unlocking member 6. During the downward movement of the unlocking member 6, the unlocking member 6 will contact the pushing surface 25 to push the locking member 4 to drive the locking sleeve 9 and the locking elastic member 8 to move in the direction away from the axis until the locking surface 5 contacts the axial limiting surface 3. Because the disassembly guide surface 26 on the locking component 4 is inclined, and the locking component 4 is in a frustum shape, and the large-diameter end of the locking component 4 is arranged toward the limiting flange 15, when the locking surface 5 contacts the axial limiting surface 3 and continues to be pushed downward, the force of the locking component 4 on the locking part 10 disappears, and the edge formed between the locking surface 5 and the pushing surface 25 of the locking part 10 will move along the disassembly guide surface 26 on the locking component 4. At this time, the unlocking component 6 and the limiting flange 15 are both below the locking part 10, and then a force is applied to the column 1 in the vertical upward direction. In the process of pulling the column 1 upward, the edge formed between the locking surface 5 and the pushing surface 25 of the locking part 10 will move in the opposite direction along the disassembly guide surface 26, and the first abutment surface 2 7 gradually separates from the axial limit surface 3. Under the action of the upward movement of the unlocking component 6, the locking portion 10 drives the locking elastic member 8 and the locking sleeve 9 to move in the direction away from the axis. At the same time, the supporting spring 22 in the avoidance groove 21 will also push the second column 18 to move in the direction away from the avoidance groove 21. Under the joint action of manpower and the reaction force of the supporting spring 22, during the common upward movement of the locking component 4 and the locking portion 10, the locking surface 5 of the locking component 4 and the axial limit surface 3 will not be separated from each other due to the existence of the unlocking elastic member 16. The column 1 continues to move upward. When the pushing surface 25 of the locking portion 10 abuts against the mounting guide surface 24 of the limiting flange 15, the supporting structure can be taken out of the disassembly hole.

[0092] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0093] By providing the plug connector assembly, the locking assembly and the unlocking component 6, it can be achieved that during the process of installing and disassembling the column 1 and the chassis 2, it is only necessary to apply a certain force downward or upward to the column 1. The plug connector assembly, the locking assembly and the unlocking component 6 cooperate with each other during the whole process of installation and disassembly, so that the installation and disassembly of the column 1 and the chassis 2 can be achieved in a simple manner. Compared with the prior art, there is no need to use screws and nuts, thereby avoiding the problem of screw and nut loss. The support structure provided by the present application is more convenient during installation and disassembly, and does not require redundant components. In addition, during installation, there is no need to reverse the chassis 2. It is only necessary to place the chassis 2 on the ground and turn the plug connector assembly to The disassembly and assembly holes on the quasi-chassis 2 can be installed by applying force downward, thus avoiding the problem that the chassis 2 is too heavy and difficult to rotate during installation, and the chassis 2 may fall to the ground and be damaged during the installation process. At the same time, the support structure designed in the present application does not need to be rotated during installation, and there is no problem of more or less engagement circles. During the installation and disassembly process, only force needs to be applied, which saves time and effort. In addition, during multiple installation and disassembly processes, there is no need to align the position, nor to fix the chassis 2 by stepping on it, but the column 1 can be directly aligned with the disassembly and assembly hole, and force can be applied to the column 1 to achieve installation. In the case of long-term disassembly and assembly, there will be no problem of wear and failure.
