[0002] Electric fans are essential appliances for cooling down the user during hot summer days. To improve their stability, they are often equipped with weights, which are typically placed on the fan's chassis.

[0003] Due to the weight of the weight block, securing it to the riser tube is a key technical issue in this field. In the prior art, securing is achieved by engaging hooks on the riser tube with the weight block. The inventors of this application have discovered that, after the hooks are engaged, they are located inside the weight block, making it difficult to deform and disassemble. Disassembly requires destroying the engaging structure, making it impossible to reinstall. Utility Model Content

[0004] The technical problem to be solved by the embodiments of the present invention is that in the prior art, the vertical pipe and the weight block of the fan are difficult to disassemble after being installed and cannot be reinstalled.

[0005] In order to solve the above problems, the present invention proposes a chassis device based on fixing rings, comprising:

[0006] vertical pipe;

[0007] A weight block, wherein the weight block is provided with a first through hole;

[0008] A panel is provided with a second through hole, one end of the second through hole extends inwardly of the panel to form a connecting tube, and a locking member is provided at the bottom end of the connecting tube; the panel is covered on the weight block, and the connecting tube passes through the first through hole; one end of the vertical tube passes through the connecting tube from the second through hole, and the locking member is affixed to the outer side of the vertical tube;

[0009] A fixing ring is detachably sleeved on the outer side of the connecting pipe, the fixing ring presses the locking piece, and the fixing ring abuts against the weight block.

[0010] A further technical solution is that the locking member includes a root sheet integrally formed and connected to the bottom end of the connecting pipe.

[0011] A further technical solution is that there are multiple root hair sheets, and the multiple root hair sheets are evenly and spaced apart at the bottom end of the connecting pipe.

[0012] A further technical solution is that the thickness of the root sheet changes from large to small from the end connected to the connecting pipe to the end away from the connecting pipe.

[0013] A further technical solution is that an inner side of the fixing ring is provided with an internal thread, an outer side of the connecting pipe is provided with an external thread, and the fixing ring is threadedly connected to the connecting pipe.

[0014] A further technical solution is that the vertical pipe includes a main body and a connecting part, the outer diameter of the connecting part is smaller than the outer diameter of the main body, the outer diameter of the connecting part is equal to the aperture of the second through hole, and the connecting part of the vertical pipe passes through the connecting pipe from the second through hole.

[0015] A further technical solution is that the length of the connecting portion is equal to the distance from the upper end surface of the second through hole to the end of the root sheet away from the connecting pipe.

[0016] A further technical solution is that the sum of the thickness of the end of the root sheet connected to the connecting pipe and the outer diameter of the connecting part of the vertical pipe is greater than the inner diameter of the fixing ring; the sum of the thickness of the end of the root sheet away from the connecting pipe and the outer diameter of the connecting part of the vertical pipe is less than the inner diameter of the fixing ring.

[0017] A further technical solution is that a receiving groove is provided at the bottom of the weight block, and the connecting pipe enters the receiving groove after passing through the first through hole, and the connecting pipe, the locking piece and the vertical pipe are all accommodated in the receiving groove.

[0018] In a second aspect, an embodiment of the present invention provides an electric fan, which includes a chassis device fixed based on a fixing ring as described in the first aspect.

[0019] Compared with the prior art, the technical effects achieved by the embodiments of the present invention include:

[0020] In the technical solution of the embodiment of the present utility model, the fixing ring is detachably sleeved on the outer side of the connecting pipe, the fixing ring presses the locking member, and the fixing ring abuts against the weight block. When the fixing ring is fixed to the connecting pipe, on the one hand, the size of the fixing ring is larger than the size of the first through hole, and the fixing ring abuts against the bottom side of the weight block; on the other hand, the fixing ring presses the locking member, and the vertical pipe is locked by the friction between the locking member and the vertical pipe, thereby achieving fixation. It can be seen that the vertical pipe and the weight block can be fixed by locking the fixing ring; the vertical pipe and the weight block can be disassembled by loosening the fixing ring; therefore, the installation and disassembly of the chassis device are very convenient.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0032] See also Figure 1-Figure 3 The present invention provides a chassis device based on a fixing ring, which is easy to install and remove and has a secure fixation. To achieve the above technical objectives, the chassis device based on the fixing ring includes a riser tube 10, a weight block 20, a panel 30, and a fixing ring 40. The specific structure is described as follows:

[0033] The riser tube 10 is used to install the head assembly of the fan.

[0034] The weight block 20 is provided with a first through hole 21. The weight block 20 can be specifically blow-molded, and the weight block 20 can increase the weight of the fan, thereby improving the stability of the fan placement.

[0035] The panel 30 is provided with a second through hole 31. One end of the second through hole 31 extends inwardly of the panel 30 to form a connecting pipe 32. The bottom end of the connecting pipe 32 is provided with a locking member 33. The axes of the first through hole 21 and the second through hole 31 are collinear.

[0036] The panel 30 is placed over the weight block 20 and can be connected to the weight block 20 via a snap fit. The connecting tube 32 passes through the first through hole 21. The outer diameter of the connecting tube 32 is the same as the diameter of the first through hole 21. One end of the riser 10 passes through the connecting tube 32 through the second through hole 31, and the locking member 33 is attached to the outer side of the riser 10.

[0037] The fixing ring 40 is detachably mounted on the outside of the connecting tube 32. The fixing ring 40 presses the locking member 33 and abuts against the weight block 20. When the fixing ring 40 is fixed to the connecting tube 32, on the one hand, the size of the fixing ring 40 is larger than the size of the first through hole 21, and the fixing ring 40 abuts against the bottom side of the weight block 20. On the other hand, the fixing ring 40 presses the locking member 33, and the friction between the locking member 33 and the stand pipe 10 locks the stand pipe 10, thereby achieving fixation. It can be seen that the stand pipe 10 and the weight block 20 can be fixed by locking the fixing ring 40; the stand pipe 10 and the weight block 20 can be disassembled by loosening the fixing ring 40. Therefore, the installation and disassembly of the chassis device are very convenient.

[0038] Furthermore, in some embodiments, such as the present embodiment, the locking member 33 includes a root sheet 331 integrally connected to the bottom end of the connecting tube 32. The root sheet 331 is a long, sheet-like structure integrally formed with the connecting tube 32, and its inner surface may be provided with anti-slip grooves to increase friction.

[0039] Furthermore, the root blades 331 are provided in multiple numbers and are evenly and spaced apart at the bottom end of the connecting tube 32. The provision of multiple root blades 331 effectively improves the reliability of the vertical tube 10. The even distribution of the root blades 331 improves the stability of the vertical tube 10.

[0040] Furthermore, the inner side of the fixing ring 40 is provided with an internal thread, and the outer side of the connecting pipe 32 is provided with an external thread, and the fixing ring 40 is threadedly connected to the connecting pipe 32. The threaded connection can effectively improve the efficiency of installing and removing the fixing ring 40 and the connecting pipe 32.

[0041] Furthermore, the riser pipe 10 includes a main body 11 and a connecting portion 12. The outer diameter of the connecting portion 12 is smaller than that of the main body 11 and equal to the diameter of the second through hole 31. The connecting portion 12 of the riser pipe 10 passes through the second through hole 31 and into the connecting pipe 32. Because the outer diameter of the main body 11 is larger than that of the connecting portion 12, and correspondingly larger than the diameter of the second through hole 31, the main body 11 cannot enter the second through hole 31, and the second through hole 31 forms a limit on the main body 11.

[0042] Furthermore, the length of the connecting portion 12 is equal to the distance from the upper end surface of the second through hole 31 to the end of the root blade 331 away from the connecting tube 32. Thus, when the connecting portion 12 is inserted into the second through hole 31 and the second through hole 31 forms a limit on the main body 11, the end of the connecting portion 12 is exactly flush with the end of the root blade 331 away from the connecting tube 32.

[0043] Furthermore, the thickness of the root sheet 331 decreases from the end connected to the connecting tube 32 to the end away from the connecting tube 32. Therefore, the more the fixing ring 40 is tightened upward (i.e., toward the weight block 20), the tighter the root sheet 331 is pressed, and the more secure the fixation is.

[0044] Furthermore, the sum of the thickness of the end of the root sheet 331 connected to the connecting tube 32 and the outer diameter of the connecting portion 12 of the stand pipe 10 is greater than the inner diameter of the fixing ring 40; and the sum of the thickness of the end of the root sheet 331 away from the connecting tube 32 and the outer diameter of the connecting portion 12 of the stand pipe 10 is less than the inner diameter of the fixing ring 40. Thus, the fixing ring 40 can be easily inserted into the end of the root sheet 331 away from the connecting tube 32, and the more the fixing ring 40 is tightened upward (i.e., toward the weight block 20), the tighter the root sheet 331 is pressed, resulting in a more secure fixation.

[0045] Furthermore, a receiving groove 22 is provided at the bottom of the weight block 20, and the connecting pipe 32 enters the receiving groove 22 after passing through the first through hole 21. The connecting pipe 32, the locking piece 33 and the vertical pipe 10 are all accommodated in the receiving groove 22 and will not protrude from the receiving groove 22, so that the weight block 20 can be placed stably on the ground, thereby improving the stability of placement.

[0046] Furthermore, the panel 30 is fixed to the weight block 20 by a hook 36. Specifically, a protruding outer portion 23 is provided on the outer edge of the upper side of the weight block 20. The panel 30 includes a main body 34 and a surrounding portion 35 formed by vertically extending downward from the outer periphery of the main body 34, and a hook 36 is provided on the inner side of the surrounding portion 35. The panel 30 covers the upper side of the weight block 20, and the surrounding portion 35 wraps around the outer side of the protrusion 23, and the hook 36 hooks the lower edge of the limiting protrusion 23. The number of the hooks 36 can be multiple, and they are evenly distributed on the inner side of the surrounding portion 35.
