In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] like Figures 1-6 As shown, the present embodiment provides a disassembly and assembly structure for disassembling and assembling a workpiece 100, the structure includes a bracket 10, a receiving cavity 11 is formed inside the bracket 10, the receiving cavity 11 is used to accommodate the workpiece 100, a clamping member 12 is provided on the inner wall of the bracket 10, the clamping end of the clamping member 12 is located in the receiving cavity 11, the clamping end of the clamping member 12 has a guiding inclined surface 121 and a limiting surface 122, when the workpiece 100 is installed along the axial direction of the bracket 10 and abuts the guiding inclined surface 121, the clamping member 12 can be elastically deformed, and the clamping end moves in a direction away from the receiving cavity 11, so that the workpiece 100 can enter the receiving cavity 11, after the workpiece 100 is installed in the receiving cavity 11, the clamping end of the clamping member 12 can return to a preset position, and the limiting surface 122 abuts against the workpiece 100, so that the workpiece 100 cannot be separated from the receiving cavity 11 along the axial direction of the bracket 10.
[0035] When the workpiece 100 needs to be installed, it is only necessary to move along the axial direction of the bracket 10 ( Figure 6 The first direction in the bracket 10 is used to push the workpiece 100 into the accommodating cavity 11. At this time, the workpiece 100 will abut the guiding inclined surface 121. At this time, the clamping member 12 will undergo elastic deformation, and the clamping end will move away from the accommodating cavity 11 as a whole, so that the workpiece 100 can smoothly enter the accommodating cavity 11. After the workpiece 100 is installed in the accommodating cavity 11, the workpiece 100 is no longer abutting against the guiding inclined surface 121, and the clamping end of the clamping member 12 returns to the preset position. At this time, the limit surface 122 abuts against the workpiece 100, and the workpiece 100 cannot be separated from the accommodating cavity 11 along the axial direction of the bracket 10. When disassembly is required, it is only necessary to push the clamping end in the direction away from the accommodating cavity 11, so that the limit surface 122 no longer restricts the workpiece 100 from moving along the axial direction of the bracket 10, and the workpiece 100 can be taken out. Therefore, this disassembly and assembly structure is convenient for installing the workpiece 100 in the bracket 10, and has a good fixing effect; at the same time, it is also convenient for disassembly, which is convenient for replacing the workpiece 100, and no special tools are needed. It is simple to operate and has strong practicality.
[0036] It should be noted here that, in this embodiment, the workpiece 100 is an axial flow motor. In other embodiments, this structure can also be used to disassemble and assemble other parts, and the scope of use of the disassembly and assembly structure is not limited in this embodiment.
[0037] like Figure 1, Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , a plurality of clamping members 12 are provided to ensure the fixing effect on the workpiece 100 and prevent it from axially disengaging from the receiving cavity 11 during operation. In addition, to ensure uniform stress on the workpiece 100, the plurality of clamping members 12 are symmetrically arranged along the inner walls of the top and bottom ends of the bracket 10. This arrangement can ensure that both the upper and lower ends of the workpiece 100 can be limited by the clamping members 12, thereby further ensuring the axial fixing effect on the workpiece 100.
[0038] As Figures 1-6 shown, guide members 13 are provided on both side walls of the bracket 10, and the extending direction of the guide members 13 is parallel to the axis of the bracket 10. By providing the guide members 13, during the installation process of the workpiece 100, the guide members 13 on both sides can abut against both sides of the workpiece 100, and the extending direction of the guide members 13 is parallel to the axis of the bracket 10 in the opposite direction. Therefore, it is ensured that during the process of pushing the workpiece 100, it will not deviate from the preset direction, thus ensuring a good installation effect. In addition, to further ensure the installation effect, a plurality of guide members 13 are provided on both side walls of the bracket 10, and the plurality of guide members 13 are evenly distributed in the vertical direction. This arrangement can further ensure a good guiding effect on both sides of the workpiece 100 from top to bottom, making the installation more convenient.
[0039] Considering that the workpiece 100 is an axial flow fan, its core is a rotating motor, and a certain rotational torque will be generated radially during its operation. To prevent this rotational torque from causing the workpiece 100 to shake during operation, as Figure 1 , Figure 4 and Figure 5 shown, mounting holes 110 are provided on the workpiece 100, and limiting members 14 are also provided inside the bracket 10. When the workpiece 100 is located in the receiving cavity 11, the limiting members 14 can be inserted into the mounting holes 110. Due to the presence of the guide members 13 on both side walls, it is ensured that the workpiece 100 can always be pushed along the first direction during the installation process. During the pushing process, the limiting members 14 can gradually be inserted into the mounting holes 110. When the workpiece 100 reaches the preset position, the limiting members 14 have been completely inserted into the mounting holes 110, so that the limiting members 14 can produce an effect of offsetting the rotational torque and ensure that the workpiece 100 does not slide radially during operation.
[0040] In addition, a plurality of mounting holes 110 are provided on the workpiece 100, and a plurality of limiting members 14 are also correspondingly provided, and the plurality of limiting members 14 are evenly arranged along the circumferential direction of the bracket 10. By this method, the workpiece 100 can be comprehensively fixed, thereby ensuring that the workpiece 100 does not deviate from the preset position along the axial and radial directions of the bracket 10, thus ensuring a good fixing effect.
[0041] In addition, a guiding portion 141 is provided at one end of the plurality of limiting members 14 that is not connected to the bracket 10. The guiding portion 141 is chamfered, and its radius gradually increases along the side closer to the connection with the bracket 10. This setting can play a good guiding role when the limiting member 14 is inserted into the mounting hole 110, thereby improving the installation efficiency.
[0042] As Figure 1 shown, the accommodating cavity 11 is generally rectangular in shape. This shape can further prevent the workpiece 100 from wobbling around the axis of the bracket 10, has a good use effect, and is convenient for installation on the support surface.
[0043] As Figures 1-6 shown, the disassembly and assembly structure further includes a base 20, and the bracket 10 is detachably connected to the base 20. By providing the base 20, it is convenient to install the disassembly and assembly structure on the support surface, and the overall stability can be ensured, and there will be no wobbling when installing the workpiece 100; in addition, since the bracket 10 and the base 20 are integrally injection-molded, integral injection molding is convenient for production and processing, the product is formed quickly, and the overall structure is more stable.
[0044] Finally, the usage process of the disassembly and assembly structure of this embodiment is described with reference to the drawings:
[0045] First, push the workpiece 100 along the Figure 6 first direction in the figure so that the workpiece 100 abuts against the guiding inclined surface 121, and continue to push the workpiece 100;
[0046] Secondly, the clamping member 12 undergoes elastic deformation, and the clamping end moves along the direction away from the accommodating cavity 11, and the workpiece 100 can smoothly enter the accommodating cavity 11;
[0047] Secondly, the clamping end returns to the preset position, the limiting surface 122 abuts against the workpiece 100, and restricts the axial movement of the workpiece 100 along the bracket 10, and the limiting member 14 can restrict the radial movement of the workpiece 100;
[0048] Finally, when the workpiece 100 needs to be disassembled, push the clamping end so that the limiting surface 122 no longer restricts the movement of the workpiece 100, and the workpiece 100 can be taken out from the inside.
[0049] In summary, the disassembly and assembly structure in this embodiment can not only achieve the efficient disassembly and assembly of the axial flow fan, but also ensure the high efficiency of the operation, and at the same time can fix the axial flow fan both axially and radially.
[0050] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
