Description

Technical Field

[0001] The utility model relates to the technical field of cooling fans, in particular to a cooling fan with a stable structure. Background Art

[0002] Cooling fans are primarily used to cool dry-type transformers and increase their capacity, as well as electronic equipment, distribution cabinets, high- and low-voltage switchgear, and other products. The cooling fan motor is a device that removes heat from the cooling system and releases it to the atmosphere. Unlike small office spaces that can use air conditioners, cooling fans are used to meet the cooling needs of industrial processes. Cooling fans come in different sizes depending on the process they are cooling.

[0003] However, due to the large size of the power fan blades, the free ends of the outer periphery of the power fan blades are more easily deformed. During high-speed operation, the deformation will affect the overall balance of the power fan blades, causing shaking, which in turn generates noise and affects the service life of the motor that drives the power fan blades. Therefore, a cooling fan with a stable structure is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a cooling fan with a stable structure in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cooling fan with a stable structure, comprising a mobile vehicle, a bottom of the mobile vehicle is fixedly connected to a moving wheel, a push handle is fixedly connected to the mobile vehicle, a cooling fan body is installed on the mobile vehicle, and a first stabilizing mechanism is connected to the mobile vehicle;

[0006] The first stabilizing mechanism includes: a bidirectional screw, which is rotatably connected to two fixed plates through a bearing, and the two fixed plates are symmetrically fixedly connected to the mobile vehicle. A threaded plate is provided on the threaded sleeve of the bidirectional screw, and the threaded plate is fixedly connected to a clamping plate.

[0007] Preferably, the mobile vehicle is fixedly connected to a chassis, the interior of which is mounted a motor, the output end of the motor being fixedly connected to a worm via a coupling, the worm being meshed with a worm wheel, and the worm wheel being fixedly connected to one end of a bidirectional screw. By providing the motor, the operation of the motor drives the worm to rotate, thereby driving the worm wheel to rotate, and the rotation of the worm wheel drives the bidirectional screw to rotate.

[0008] Preferably, the threaded plate is L-shaped, with two threaded plates and two clamping plates respectively, symmetrically arranged on the forward and reverse threads of the bidirectional screw. The two threaded plates and two clamping plates are slidably connected to the mobile vehicle. By providing the threaded plates, the rotation of the bidirectional screw can drive the two threaded plates toward or away from each other, thereby driving the two clamping plates toward or away from each other, so that the two clamping plates can be pressed against the two sides of the cooling fan body during the movement toward each other, achieving a stabilizing effect and preventing the cooling fan from shaking during use.

[0009] Preferably, the mobile vehicle is connected to a second stabilizing mechanism, comprising a synchronous belt assembly, wherein the bidirectional screw is connected to a rotating shaft via the synchronous belt assembly, the rotating shaft being rotatably connected to a connecting plate, and the connecting plate being fixedly connected to the bottom of the mobile vehicle. The provision of the connecting plate serves to limit the installation of the rotating shaft, and the synchronous belt assembly is configured as a sprocket chain, with two sprockets respectively mounted on the rotating shaft and the bidirectional screw, and driven by the chain, so that the rotation of the bidirectional screw synchronously drives the rotation of the rotating shaft.

[0010] Preferably, a gear is fixedly connected to the rotating shaft, the gear meshingly connected to a toothed column, the toothed column is slidably connected to a limit frame, the limit frame is fixedly connected to the mobile vehicle, and the bottom of the toothed column is fixedly connected to the bottom plate. By providing a gear, the rotation of the rotating shaft drives the gear, which in turn drives the toothed column and the bottom plate downward, thereby supporting the ground, increasing stability, and avoiding instability caused by vibration of the cooling fan.

[0011] Preferably, the number of the gear, the limiting frame, the gear column and the base plate are two respectively, and they are symmetrically arranged.

[0012] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This cooling fan with a stable structure, by setting a threaded plate, can drive the two threaded plates to approach or move away from each other under the rotation of the bidirectional screw, and then drive the two clamping plates to approach or move away from each other, so as to achieve the purpose of making the two side clamping plates press against the two sides of the cooling fan body under the movement of approaching each other, thereby achieving a stabilizing effect and preventing the cooling fan from shaking during use.

[0014] 2. This cooling fan with a stable structure is equipped with gears. The gears are driven by the rotation of the rotating shaft to rotate, thereby driving the gear column to move downward and driving the bottom plate to move downward, thereby supporting the ground, increasing stability, and avoiding instability caused by vibration of the cooling fan.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "several" means two or more, unless otherwise specifically defined.

[0023] See also Figure 1-3 One embodiment of the present utility model is: a cooling fan with a stable structure, comprising a mobile vehicle 1, a mobile wheel 2 fixedly connected to the bottom of the mobile vehicle 1, a push handle 4 fixedly connected to the mobile vehicle 1, a cooling fan body 3 installed on the mobile vehicle 1, and a first stabilizing mechanism 5 connected to the mobile vehicle 1;

[0024] The first stabilizing mechanism 5 includes: a bidirectional screw 504, which is rotatably connected to two fixed plates 505 through a bearing. The two fixed plates 505 are symmetrically fixedly connected to the mobile vehicle 1, and a threaded plate 506 is threadedly sleeved on the bidirectional screw 504, and the threaded plate 506 is fixedly connected to a clamping plate 507.

[0025] The mobile vehicle 1 is fixedly connected to a chassis 501, which houses a motor. The motor's output end is fixedly connected to a worm 502 via a coupling. The worm 502 is meshed with a worm gear 503, which is fixedly connected to one end of a bidirectional screw 504. The motor drives the worm 502 to rotate, which in turn drives the worm gear 503 to rotate. The rotation of the worm gear 503 drives the bidirectional screw 504 to rotate.

[0026] The threaded plates 506 are L-shaped, with two threaded plates 506 and two clamping plates 507 symmetrically arranged on the forward and reverse threads of the bidirectional screw 504. The two threaded plates 506 and clamping plates 507 are slidably connected to the mobile vehicle 1. By providing the threaded plates 506, the rotation of the bidirectional screw 504 can drive the two threaded plates 506 toward or away from each other, thereby driving the two clamping plates 507 toward or away from each other. As a result, the clamping plates 507 on both sides of the cooling fan body 3 are pressed against each other during the movement of the two clamping plates 507 toward each other, achieving a stabilizing effect and preventing the cooling fan from shaking during use.

[0027] Working principle: By controlling the motor to start, the operation of the motor drives the worm 502 to rotate, and then drives the worm wheel 503 to rotate. The rotation of the worm wheel 503 drives the bidirectional screw 504 to rotate. The rotation of the bidirectional screw 504 drives the two splints 507 to move closer to each other, and then allows the two side splints 507 to press against the two sides of the cooling fan body 3.

[0028] See also Figure 1-3In another embodiment of the present invention, based on the above embodiment, a second stabilizing mechanism 6 is connected to the mobile vehicle 1. The second stabilizing mechanism 6 includes a synchronous belt assembly 601, through which the bidirectional screw 504 is connected to a rotating shaft 603. The rotating shaft 603 is rotatably connected to a connecting plate 602, which is fixedly connected to the bottom of the mobile vehicle 1. The provision of the connecting plate 602 serves to limit the installation of the rotating shaft 603. The synchronous belt assembly 601 is configured as a sprocket chain, with two sprockets respectively mounted on the rotating shaft 603 and the bidirectional screw 504. Through the chain transmission, the rotation of the bidirectional screw 504 synchronously drives the rotation of the rotating shaft 603.

[0029] A gear 604 is fixedly connected to the rotating shaft 603, which is meshed with a toothed post 606. The toothed post 606 is slidably connected to a limit frame 605, which is fixedly connected to the mobile vehicle 1. The bottom of the toothed post 606 is fixedly connected to a base plate 607. By providing the gear 604, the rotation of the rotating shaft 603 drives the gear 604, which in turn drives the toothed post 606 and the base plate 607 downward, thus supporting the ground, increasing stability, and preventing instability caused by vibration of the cooling fan body 3.

[0030] The number of the gear 604 , the limiting frame 605 , the gear column 606 and the bottom plate 607 are two respectively, and they are symmetrically arranged.

[0031] Working principle: The bidirectional screw 504 rotates synchronously with the rotating shaft 603 through the synchronous belt assembly 601, and then drives the gear 604 to rotate. The rotation of the rotating shaft 603 drives the gear 604 to rotate, and then drives the gear column 606 to move downward, and drives the bottom plate 607 to move downward, which has the effect of supporting the ground, increasing stability, and avoiding instability caused by vibration of the cooling fan body 3.

[0032] It is worth noting that: in this embodiment, the motor is a commonly used device in the prior art, and the model used can be customized according to actual usage requirements, and the power supply interface of the electrical equipment in this utility is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to achieve its control. The circuits and controls involved are all prior art and are well known in the current field of technology, so they will not be elaborated on here.
