Description

Technical Field

[0001] This utility model relates to the field of tower fan chassis technology, specifically to a tower fan chassis that is easy to install and disassemble. Background Technology

[0002] Tower fans, also known as tower-type fans, are a common type of fan popular with consumers for their unique appearance and performance characteristics. Tower fans are typically designed with a slender, tower-shaped structure, making them relatively long and compact, generally around 1 meter in height or even taller. Their casings are mostly made of plastic, featuring a simple, streamlined design, elegant lines, and a stylish appearance that blends well into various home and office environments. They primarily rely on a built-in motor to drive a cross-flow fan, which consists of multiple blades. Driven by the motor, the blades rotate at high speed, drawing air in from one side of the tower fan, accelerating it through the air duct, and then blowing it out in a columnar shape from the other side, creating a gentle airflow similar to natural wind. This unique air delivery method results in a relatively wide airflow range and a more uniform airflow speed, providing a comfortable experience.

[0003] Existing tower fan chassis have some shortcomings in the installation and disassembly process. Traditional tower fan chassis are usually connected to the tower fan body by screws. This connection method requires tools to tighten each screw individually during installation, which is cumbersome and time-consuming. Similarly, disassembly also requires tools to unscrew each screw, which is not only inefficient but may also be difficult for users who are not familiar with the operation. Therefore, there is an urgent need for a tower fan chassis that is easy to install and disassemble to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a tower fan chassis that is easy to install and disassemble, which has the advantage of being easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tower fan chassis that is easy to install and disassemble, comprising a tower fan body and a tower fan chassis assembly, wherein the tower fan chassis assembly comprises a base, a receiving seat, a positioning slide column, a positioning block, a slot, a turntable, a limiting top seat, a through groove, a fixing groove, a square groove, a spring, a first slider, a second slide groove, a second slider, a moving rod, a hemisphere, a threaded rod, a receiving groove, and a first slide groove.

[0006] Furthermore, the tower fan body is located on top of the tower fan chassis assembly, and a limiting top seat is fixedly installed at the bottom of the tower fan body. A through groove is opened at the top of the inner cavity of the limiting top seat, and a uniformly distributed fixing groove is opened inside the limiting top seat and on the surface of the through groove. A square groove is opened inside the limiting top seat and at the top of the through groove.

[0007] Furthermore, the bottom of the limiting top seat is provided with a base, the inner cavity of the base is provided with a turntable, the top of the base is connected to a receiving seat, and a positioning block is fixedly installed on the top of the receiving seat.

[0008] Furthermore, the interior of the receiving seat is provided with evenly distributed slots, the inner cavity of the slots is provided with positioning slide posts, and the two sides of the positioning slide posts are provided with first slide grooves, and the interior of the first slide grooves is slidably connected with first sliders.

[0009] Furthermore, the side of the first slider that is relatively far away from the inner cavity of the slot is fixedly connected, and a spring is fixedly installed in the inner cavity of the first slot and inside the first slider. The inner cavity of the receiving seat is provided with a hemisphere, and the inside of the base is provided with a receiving groove.

[0010] Furthermore, the inner cavity of the receiving groove is provided with a movable rod, the top of the movable rod is fixedly connected to the bottom of the hemisphere, and the base is provided with a second sliding groove on both sides of the receiving groove, and a second slider is slidably connected inside the second sliding groove.

[0011] Furthermore, the side of the second slider that is relatively close to each other is fixedly connected to both sides of the moving rod, and the inside of the moving rod is connected to a threaded rod by a threaded rotation. The bottom of the threaded rod extends through to the bottom of the base and is fixedly connected to the top of the turntable.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This invention features a tower fan body that generates a gentle airflow similar to natural wind to blow air onto the user. The tower fan chassis assembly facilitates the fixation of the bottom of the tower fan body, increasing its stability. During use, the tower fan body moves downwards, causing the limiting top seat to move downwards as well. Then, a positioning block passes through a square slot into the interior of the limiting top seat, while a receiving seat inserts into the inner cavity of the through slot. After insertion to the designated position, rotating the turntable causes the threaded rod to rotate, which in turn moves the moving rod and hemisphere upwards. Under the action of the hemisphere, the positioning sliding pin passes through the fixing slot into the interior of the limiting top seat, thus fixing the limiting top seat and the tower fan body. This design offers the advantage of convenient installation and disassembly, solving the problem of traditional tower fan chassis being connected to the tower fan body using screws. This connection method requires tightening each screw individually with tools during installation, which is cumbersome and time-consuming. Similarly, disassembly also requires unscrewing each screw individually with tools, which is not only inefficient but may also pose a challenge for users unfamiliar with the operation.

[0019] In some embodiments, the receiving seat 22 has evenly distributed slots 25 inside, and the inner cavity of the slots 25 is provided with a positioning slide post 23. The positioning slide post 23 has a first slide groove 210 on both sides. The first slide groove 210 is slidably connected to the inside of the first slide groove 210. More specifically, the positioning slide post 23 is received by setting the slots 25, and the first slide groove 210 is used to limit the first slide post 293.

[0020] In some embodiments, the side of the first slider 293 that is relatively far away from the inner cavity of the slot 25 is fixedly connected, and a spring 292 is fixedly installed in the inner cavity of the first slide groove 210 and inside the first slider 293. The inner cavity of the receiving seat 22 is provided with a hemisphere 297, and the inside of the base 21 is provided with a receiving groove 299. More specifically, the positioning slide 23 is limited by the first slider 293 to prevent the positioning slide 23 from shaking during movement, and the positioning slide 23 is reset by the spring 292.

The bottom of the threaded rod 298 extends through to the bottom of the base 21 and is fixedly connected to the top of the turntable 26. More specifically, the second slider 295 is used to limit the moving rod 296 to prevent the moving rod 296 from shaking during movement. The moving rod 296 is used to move the hemisphere 297.

[0023] Working principle: Step 1: By setting the tower fan body 1, a gentle airflow similar to natural wind is generated to blow air to the user. The tower fan chassis assembly 2 is set to fix the bottom of the tower fan body 1 and increase its stability. When in use, the tower fan body 1 moves downward, and the tower fan body 1 drives the limiting top seat 27 to move downward. Then, the positioning block 24 passes through the square groove 291 into the interior of the limiting top seat 27, and at the same time, the receiving seat 22 is inserted into the inner cavity of the through groove 28. Step 2: After inserting into the designated position, rotate the turntable 26. The turntable 26 drives the threaded rod 298 to rotate, causing the moving rod 296 to move the hemisphere 297 upward.
