Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and in particular to a small axial flow fan assembly that is easy to transport. Background Technology

[0002] Axial flow fans are widely used; they are a type of fan where the airflow direction is the same as the fan blade axis, such as electric fans and air conditioner outdoor unit fans. They are called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. While axial flow fans are fixed in position and move air, small axial flow fans are widely used in industrial production and daily life, but they generally present difficulties in transportation.

[0003] Traditional fans typically use fixed bases or simple support structures, requiring multiple people to lift them or using additional handling tools when moving them. This is not only labor-intensive and inefficient, but also prone to collision damage. Although some fans are equipped with casters, the casters are mostly fixed and exposed, making them impossible to store. This results in poor stability during operation, causing vibration and displacement, which affects normal operation. Therefore, a small axial flow fan assembly that is easy to move is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a small axial flow fan assembly that is easy to transport. It aims to solve the problem that existing fans typically use fixed bases or simple support structures, requiring multiple people to lift or use additional handling tools when moving them. This not only results in high labor intensity and low efficiency but also easily causes equipment collision damage. Although some fans are equipped with casters, the casters are mostly fixed, exposed structures that cannot be stored, leading to poor stability during operation, easy vibration and displacement, and affecting normal operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a small axial flow fan assembly that is easy to transport, including a fan body, a support plate fixedly connected to the bottom of the fan body, a moving mechanism provided on the side wall of the support plate, and a rubber buffer pad fixedly connected to the bottom of the support plate. The moving mechanism includes a fixed cylinder, a push rod slidably connected to the inner wall of the fixed cylinder, a fixed ring fixedly connected to the outer wall of the push rod, a connecting block fixedly connected to the bottom of the fixed ring, a positioning post fixedly connected to the left wall of the connecting block, a spring sleeved on the outer wall of the push rod, a wheel frame rotatably connected to the outer wall of the fixed cylinder via a bearing, a movable wheel rotatably connected to the inner wall of the wheel frame via a bearing, and a positioning disc fixedly connected to the front of the wheel frame.

[0006] As a further description of the above technical solution: the fixed cylinder is fixedly connected to the inner wall of the support plate, and the inner wall of the fixed cylinder is provided with a guide hole.

[0007] As a further description of the above technical solution: the right end of the push rod is inserted into the inner wall of the guide hole, and the left end of the push rod is fixedly connected to a pressing block.

[0008] As a further description of the above technical solution: a first positioning hole is provided on the right wall of the positioning disk, the left end of the positioning pin is inserted into the inner wall of the first positioning hole, and a second positioning hole is provided on the right wall of the positioning disk.

[0009] As a further description of the above technical solution: one end of the spring abuts against the right wall of the fixed ring, and the other end of the spring abuts against the inner wall of the fixed cylinder.

[0010] As a further description of the above technical solution: the side wall of the support plate is provided with a limiting component, the limiting component including a limiting plate, the limiting plate being disposed on the right wall of the support plate.

[0011] As a further description of the above technical solution: a slot is provided on the right wall of the support plate, an insert plate is fixedly connected to the inner wall of the slot, and the left wall of the limiting plate is fixedly connected to the right wall of the insert plate.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the positioning column can be quickly switched and locked with the first positioning hole and the second positioning hole through the telescopic cooperation of the push rod and the spring. This allows the wheel frame to be unfolded for movement or stored for fixation, solving the contradiction between the inconvenience of traditional fan handling and poor stability during operation. A single person can easily complete the fan relocation and state switching, improving the convenience of operation and work efficiency.

[0013] 2. In this utility model, the limiting structure composed of the limiting plate, the insert plate, and the slot precisely limits the rotation angle of the wheel frame to 90°. When the user rotates the wheel frame, there is no need to visually align it to the correct position, avoiding the tedious operation of repeated calibration and improving the reliability of the locking mechanism and the user experience.

[0014] 3. In this utility model, a rubber buffer pad is set at the bottom of the support plate. The rubber buffer pad absorbs the vibration energy generated by the fan during operation through elastic deformation, reduces the vibration transmitted to the foundation structure, reduces the resonance effect between the equipment and the ground, effectively reduces vibration and noise, and also protects the bottom of the support plate to prevent wear.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3The present invention provides an embodiment of a small axial flow fan assembly that is easy to transport, including a fan body 1, a support plate 4 fixedly connected to the bottom of the fan body 1, a moving mechanism 2 provided on the side wall of the support plate 4, which can be extended and moved when the fan is transported by the moving mechanism 2 that can be stored, and a rubber buffer pad 5 fixedly connected to the bottom of the support plate 4. The rubber buffer pad 5 absorbs the vibration energy generated by the fan during operation through elastic deformation, reduces the vibration transmitted to the foundation structure, reduces the resonance effect between the equipment and the ground, effectively reduces vibration and noise, and also protects the bottom of the support plate 4 to prevent wear on the bottom of the support plate 4. The moving mechanism 2 includes a fixed cylinder 201. A push rod 202 is slidably connected to the inner wall of the fixed cylinder 201. A fixed ring 206 is fixedly connected to the outer wall of the push rod 202. A connecting block 207 is fixedly connected to the bottom of the fixed ring 206. A positioning post 208 is fixedly connected to the left wall of the connecting block 207. The movement of the push rod 202 can cause the fixed ring 206 to drive the connecting block 207 to move, thereby moving the positioning post 208 away from the positioning plate 205. A spring 209 is sleeved on the outer wall of the push rod 202. A wheel frame 204 is rotatably connected to the outer wall of the fixed cylinder 201 through a bearing. A movable wheel 211 is rotatably connected to the inner wall of the wheel frame 204 through a bearing. A positioning plate 205 is fixedly connected to the front of the wheel frame 204. The movable wheel 211 facilitates the movement of the fan assembly. The positioning plate 205, in conjunction with the positioning post 208, can lock the wheel frame 204.

[0019] Reference Figure 4 - Figure 5 , Figure 8 The fixed cylinder 201 is fixedly connected to the inner wall of the support plate 4. A guide hole 210 is provided on the inner wall of the fixed cylinder 201. The right end of the push rod 202 is inserted into the inner wall of the guide hole 210. The guide hole 210 serves to limit and guide the push rod 202. A button block 203 is fixedly connected to the left end of the push rod 202. The button block 203 allows the user to press the button block 203 to push the push rod 202 to the right. A first positioning hole 212 is provided on the right wall of the positioning plate 205. The left end of the positioning pin 208 is inserted into the inner wall of the first positioning hole 212. The positioning pin 208 works in conjunction with the first positioning hole 212. 208 can lock the stored wheel frame 204. The right wall of the positioning plate 205 has a second positioning hole 213. When the wheel frame 204 needs to be lowered, the user can press the button 203 to push the push rod 202 to the right, so that the positioning pin 208 is disengaged from the first positioning hole 212 under the action of the connecting block 207. At this time, the wheel frame 204 is unlocked and can rotate downward 90° so that the moving wheel 211 on the wheel frame 204 contacts the ground. Then, the button 203 is released so that the positioning pin 208 is inserted into the second positioning hole 213 under the action of the spring 209, thus locking the wheel frame 204.

[0020] One end of the spring 209 abuts against the right wall of the fixed ring 206, and the other end of the spring 209 abuts against the inner wall of the fixed cylinder 201. The spring 209 facilitates the reset of the push rod 202.

[0021] Reference Figure 6 - Figure 7 The side wall of the support plate 4 is provided with a limiting component 3, which includes a limiting plate 301. The limiting plate 301 is located on the right wall of the support plate 4. A slot 303 is provided on the right wall of the support plate 4. An insert plate 302 is fixedly connected to the inner wall of the slot 303. The left wall of the limiting plate 301 is fixedly connected to the right wall of the insert plate 302. The wheel frame 204 can be limited by the setting of the limiting plate 301. Since the setting of the limiting plate 301 limits the rotation range of the wheel frame 204 to 90°, the wheel frame 204 does not need to be deliberately calibrated and locked by the user when it is retracted.

[0022] Working principle: During transport, pressing the button 203 causes the push rod 202 to slide inward along the guide hole 210 of the fixed cylinder 201, driving the fixed ring 206, connecting block 207, and positioning post 208 to move synchronously. The spring 209 is compressed, and the positioning post 208 disengages from the first positioning hole 212. Subsequently, the wheel frame 204 is rotated 90° outward around the fixed cylinder 201 to the unfolded state, and the limiting plate 301 restricts the excessive rotation of the wheel frame 204. Releasing the button 203 causes the spring 209 to return to its original position and push the fixed ring 206, causing the positioning post 208 to insert into the second positioning hole 213 of the positioning plate 205, locking the position of the wheel frame 204. The moving wheel 211 then contacts the ground to achieve pushing and transport.

[0023] When fixed operation is required, press the button 203 again, and the push rod 202 pushes the positioning column 208 to disengage from the second positioning hole 213. Rotate the wheel frame 204 90° in the opposite direction to the storage state. At this time, the positioning column 208 is inserted into the first positioning hole 212 and locked under the action of the spring 209. The moving wheel 211 is off the ground, and the support plate 4 is directly grounded to ensure the stable operation of the fan body 1.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
