Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan with an adjustable bracket. Background Art

[0002] As a ventilation equipment widely used in industries such as industry, construction, and transportation, fans play an important role in improving indoor air quality, ensuring production safety, and improving living comfort. For example, the utility model with patent number 202321809431.3 includes a fan body, and the fan body includes a wind tube. A protective net is fixed to the mouth of the wind tube, and a bracket seat is provided under the wind tube. Although the device can adjust the air outlet direction of the fan, due to manual adjustment, the fan itself is large in size and heavy in weight. Manual adjustment of the air outlet angle is undoubtedly inconvenient, and the operation is time-consuming and laborious. In addition, when moving the fan, due to its large size and difficulty in operation, it is easy to bump into it, which may cause damage to the fan, affect its use, and bring a lot of troubles to people. Therefore, based on the above shortcomings, a fan with an adjustable bracket is now introduced to improve this. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3The utility model provides a technical solution: a fan with an adjustable bracket, including a base 1, universal wheels 2 are installed at the four corners of the bottom end of the base 1, a base 3 is installed at the top of the base 1, first support rods 4 are arranged at the front and rear ends of the upper surface of the right side of the base 3, the inner sides of the two first support rods 4 are rotatably connected to the fan 5 through bearings, guide rods 6 are arranged on the front and rear sides of the inner cavity of the base 3, the outer wall of the guide rod 6 is provided with a connecting plate 7, a roller 8 is installed at the bottom end of the connecting plate 7, and a screw at the center position of the right side of the inner cavity of the base 3 is provided. A motor 9 is connected, and one end of a screw rod 10 is installed at the left output end of the motor 9. The other end of the screw rod 10 passes through the connecting plate 7 and is rotatably connected to the inner wall of the base 3 through a bearing. The screw rod 10 and the connecting plate 7 are threadedly connected to each other. One end of a bottom plate 11 is provided at the top of the connecting plate 7, and the other end of the bottom plate 11 extends out of the upper surface of the base 3. One end of a second support rod 12 is pin-connected to the front and rear sides of the top of the bottom plate 11, and the other end of the second support rod 12 is rotatably connected to the outer wall of the fan 5 through a bearing.

[0016] As a preferred solution, further, springs 13 are installed on the circumference of the outer wall of the base 3, baffles 14 are installed on the outside of the springs 13, and rubber pads 15 are arranged on the outside of the baffles 14. The baffles 14 can protect the base 3 from bumps, and the elasticity of the rubber pads 15 themselves and the elastic force of the springs 13 can effectively alleviate the impact, thereby protecting the whole from damage.

[0017] As a preferred solution, further, a handle 16 is installed on the outer wall of the first support rod 4, and the handle 16 is used to facilitate pushing and carrying the entire body.

[0018] As a preferred solution, further, the roller 8 and the base 3 are arranged to fit each other, and the roller 8 can facilitate the movement of the connecting plate 7.

[0019] As a preferred solution, further, a battery is built into the motor 9, and the battery can be used alone.

[0020] The electrical components mentioned in this solution are all existing technologies, and their models are only one of them. Any electrical components that can achieve the purpose of this solution can be used.

[0021] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control. The specific work is as follows.

[0022] When in use, the motor 9 is turned on, and the motor 9 drives the screw 10 to rotate. Since the screw 10 and the connecting plate 7 are threadedly connected to each other, when the screw 10 rotates, the connecting plate 7 threadedly connected to its outer wall can drive the bottom plate 11, the roller 8 and one end of the second support rod 12 to move left or right together. When one end of the second support rod 12 moves left and right, the other end of the second support rod 12 will drive the air outlet end of the fan 5 to flip up and down and move and adjust, so that the angle of the air outlet can be adjusted according to the use requirements. When the angle adjustment is completed, the motor 9 is turned off, the screw 10 stops rotating, and the air outlet end of the fan 5 is turned left and right. The angle is also fixed immediately; when a bump occurs during the overall transportation and movement, the external collision will hit the rubber pad 15 and squeeze the spring 13 through the baffle 14. The elasticity of the rubber pad 15 itself and the elastic force of the spring 13 can effectively alleviate the impact, thereby protecting the whole and avoiding damage; the device adopts an electric adjustment method. Compared with the traditional manual adjustment, the electric adjustment of the air outlet direction is not only simple and convenient, but also time-saving and labor-saving. Moreover, its protection function can effectively avoid the blower from being damaged by bumps, protect the equipment, and is easy to use. It is highly practical and suitable for promotion.
