Description

Technical Field

[0001] This utility model relates to the field of lifting fans, specifically a support component for lifting fans. Background Technology

[0002] The support assembly for a height-adjustable fan is a component that provides height adjustment and support for the fan. A search revealed a utility model patent with application number CN202220410346.9, which discloses a height-adjustable fan bracket. This bracket includes a base, a column welded to the top outer wall of the base, a sleeve fitted onto the outer wall of the column, a groove on the top inner wall of the sleeve, two sliding plates slidably connected inside the groove, uprights welded to the bottom outer walls of the two sliding plates, short posts welded to one side outer wall of each of the two uprights, springs fitted onto the outer walls of the two short posts, and positioning blocks provided on the bottom side walls of the two springs. A central groove is formed inside the column, and several positioning grooves are formed on the inner wall of the central groove. A pin hole is formed on the outer wall of the sleeve, and a push rod is slidably connected inside the pin hole. A baffle is fixedly fitted onto the outer wall of the push rod. This utility model uses positioning blocks that engage with positioning grooves of different heights, allowing the height of the uprights to change, facilitating user adjustment of the sleeve height. This makes it suitable for different users and more convenient to use.

[0003] However, the existing support components for elevating fans, due to their lifting function, cause their center of gravity to rise along with the fan. This necessitates a base with a large surface area to ensure fan stability and prevent significant swaying or tipping during operation. However, making the base too large hinders fan storage. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a support component for a lifting fan, which solves the problem of unstable support caused by the lifting and lowering of the existing support components for lifting fans, and also solves the problem of storage of the support component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support assembly for a lifting fan, including a base, the base being a flat cylindrical platform, a lifting mechanism being provided on the top of the base, an installation mechanism being provided on the top of the lifting mechanism, a plurality of spaced strip grooves II being provided at the bottom edge of the base, the strip grooves II being arranged along the radial direction of the base, a strip groove I being provided at the edge of the base, the strip groove I and the strip groove II being one-to-one corresponding and perpendicularly arranged, a limit rod being vertically installed in the middle of the strip groove I, the end of the limit rod being connected to a limit plate, a strip-shaped support seat being provided in the strip groove I, the support seat having a limit groove I being provided, the limit groove I being corresponding to the limit rod, and a limit groove II being provided at the bottom of the support seat, the limit groove II being corresponding to the limit plate.

[0006] Preferably, the bottom of the support base is equipped with anti-slip pads. These anti-slip pads increase the friction between the support base and the ground, thereby improving the base's support capacity.

[0007] Preferably, the lifting mechanism includes a support tube, which is vertically fixed to the top of the base. A sleeve is fitted onto the top of the support tube, and the mounting mechanism is fixed to the top of the sleeve. A screw is coaxially mounted inside the sleeve, and the top of the screw is fixed to the top of the sleeve. A nut is threaded onto the screw and is fixedly installed inside the upper end of the support tube. The threaded connection of the screw within the support tube allows rotation between the sleeve and the support tube, controlling the extension and retraction of the sleeve on the support tube, thereby adjusting the height of the fan.

[0008] Preferably, a baffle is installed at the bottom of the screw, and the edge of the baffle is in clearance fit with the inner wall of the support tube. The baffle limits the rotation of the screw on the nut to prevent the support tube from separating from the sleeve.

[0009] Preferably, multiple reinforcing plates are installed at the bottom of the support tube, with one side of each reinforcing plate fixed to the base and the other side fixed to the outer wall of the support tube. The reinforcing plates improve the connection strength between the support tube and the base, thereby enhancing the support capacity of the support tube.

[0010] Preferably, a locking bolt is threaded to the bottom side of the sleeve, with the end of the locking bolt penetrating the sleeve and corresponding to the outer wall of the support tube. The locking bolt reinforces the fixation between the sleeve and the support tube.

[0011] Preferably, the mounting mechanism includes a connecting seat fixed to the top of the sleeve. A U-shaped bracket with an upward-facing opening is mounted on the top of the connecting seat, and fasteners are provided on both sides of the top of the U-shaped bracket. The fan is placed and secured using the U-shaped bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows the support base to slide and deflect within the first strip groove, enabling it to be rotated to the same direction as the second strip groove and extend outward from the first strip groove. This increases the contact area between the base and the ground, thereby improving the support strength of the support assembly after the fan is raised. Furthermore, the extension length of the support base can be adjusted by sliding within the second strip groove, allowing for control of the extension length in conjunction with the fan's height adjustment, thus providing better support for the fan.

[0014] 2. This utility model allows the support base to be stored in the strip groove by rotating and sliding, thereby reducing the overall frontal projection area of ​​the base, reducing the space occupied by the base, and facilitating the storage of the support components.

The lifting mechanism 2 includes a support tube 11, which is vertically fixed to the top of the base 1. Multiple reinforcing plates are installed at the bottom of the support tube 11, with one side of each plate fixed to the base 1 and the other side fixed to the outer wall of the support tube 11. The reinforcing plates enhance the connection strength between the support tube 11 and the base 1, thereby improving the support capacity of the support tube 11. A sleeve 12 is fitted onto the top of the support tube 11, and an installation mechanism 3 is fixed to the top of the sleeve 12. A screw 13 is coaxially mounted inside the sleeve 12, with its top fixed to the top of the sleeve 12. A nut 14 is threaded onto the screw 13. The nut 14 is fixedly installed inside the upper end of the support tube 11. A screw 13 is threadedly connected within the support tube 11, allowing rotation between the sleeve 12 and the support tube 11. This controls the extension and retraction of the sleeve 12 on the support tube 11, thereby adjusting the height of the fan. A baffle 15 is installed at the bottom of the screw 13, with its edge fitting against the inner wall of the support tube 11. The baffle 15 limits the rotation of the screw 13 on the nut 14, preventing the support tube 11 from detaching from the sleeve 12. A locking bolt 16 is threadedly connected to the bottom side of the sleeve 12. The end of the locking bolt 16 penetrates the sleeve 12 and corresponds to the outer wall of the support tube 11, reinforcing the fixation between the sleeve 12 and the support tube 11.

[0022] Please see Figure 1 The top of the lifting mechanism 2 is provided with a mounting mechanism 3, which includes a connecting seat 17. The connecting seat 17 is fixed to the top of the sleeve 12. A U-shaped seat 18 with an upward opening is installed on the top of the connecting seat 17. Fasteners 19 are provided on both sides of the top of the U-shaped seat 18. The fan is placed and fixed through the U-shaped seat 18.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The base 1 has several spaced strip grooves 5 at its bottom edge, which are arranged radially along the base 1. A strip groove 4 is also provided at the edge of the base 1, corresponding to and perpendicular to the strip grooves 5.

A limit groove 9 is provided at the bottom of the support seat 7, corresponding to the limit plate 10. Anti-slip pads are installed at the bottom of the support seat 7 to increase the friction between the support seat 7 and the ground, thereby improving the support capacity of the base 1.

[0024] The specific implementation process of this utility model is as follows: When in use, take the fan and place it in the U-shaped base 18 and install and fix it with fasteners 19. If the height of the fan is not suitable, you can hold the sleeve 12 with one hand and the support tube 11 with the other hand and rotate it to control the extension and retraction of the support tube 11 in the sleeve 12, thereby adjusting the height of the fan. When the height of the fan is high, you can pull the support seat 7 until the limiting rod 6 abuts against the end of the limiting groove 8 and then rotate the support seat 7 to rotate the support seat 7 from under the base 1, thereby increasing the contact area between the base 1 and the ground and allowing the fan to get more stable support. When the height of the fan is low, you can rotate the support seat 7 to push it back into the strip groove, thereby storing the support seat 7 and not taking up too much space.
