Description

Technical Field

[0001] The utility model relates to the technical field of fan impellers, in particular to a fan impeller locking device. Background Art

[0002] The fan impeller is one of the core components of the fan. It is usually composed of multiple blades and a hub, and is made of various materials, such as metal, plastic, etc. The main function of the fan impeller is to rotate under the drive of the motor to generate airflow. The rationality of its design directly affects the performance of the fan, including air volume, air pressure, efficiency, etc. Different types of fan impellers are suitable for different application scenarios. For example, centrifugal fan impellers are suitable for high pressure and small flow occasions, while axial flow fan impellers are suitable for large flow and low pressure situations.

[0003] Prior art, such as the utility model with publication number CN218030806U, discloses a fan impeller locking device, which adopts an impeller brake disc, wherein a housing is provided at the upper end of the impeller brake disc, a rotating rod is rotatably provided at the right end inside the housing, a worm is rotatably provided at the left end inside the housing, a threaded rod is rotatably provided between the rotating rod and the worm inside the housing, a connecting rod is threadedly provided at the bottom of the threaded rod, the bottom end of the connecting rod passes through the interior of the housing and is provided with a locking mechanism, a disc is provided at the upper part of the housing, and the upper right end of the disc is provided with a locking mechanism. A motor is provided at the end, and the output shaft of the motor is connected to the top of the rotating rod. The locking mechanism includes a connecting plate and two fixed blocks, and the connecting plate is installed at the bottom of the connecting rod. When the utility model is in use, the locking effect of the impeller brake disc is good, and it is also simple and convenient to cancel the lock. At the same time, the impeller brake disc can be locked in a variety of ways, which greatly improves the practicality of the device and solves the problem that a locking pin is usually used to lock it when locking, but the locking pin is easily stuck with the positioning hole of the impeller brake disc when locking, which makes it more troublesome to remove the locking pin.

[0004] In the process of locking the fan impeller with the help of a locking device, there is a problem that the existing locking device, such as the above-mentioned one, has a relatively high overall height. Since the use environment of the fan is relatively complex, when the use space of the fan is relatively narrow, the excessively high locking device will interfere with the normal installation of the fan. At the same time, its locking structure and the brake pad adopt a split design. When working, it is necessary to control the locking mechanism to be inserted into the groove opened on the surface of the brake pad. When the groove on the surface of the brake pad is offset from the locking mechanism, the locking mechanism is difficult to insert into the brake pad and effectively lock the brake pad. Utility Model Content

[0010] Preferably, a side surface of the mounting frame is fixedly connected with a vertical plate, and the vertical plate is fixedly connected to the surface of the connecting plate. The vertical plate can increase the structural strength between the connecting plate and the mounting frame to improve the firmness of the connecting plate.

[0011] Preferably, there are two mounting frames, which are symmetrically arranged with respect to the frame, and the number of connecting columns matches the mounting frames. Through the cooperation between the mounting frames and the connecting columns, the position of the brake pad can be constrained to reduce the probability of the brake pad rotating.

[0012] Preferably, there are two connecting plates, which are symmetrically arranged about the vertical plate, and the width of the connecting plate is equal to the width of the mounting frame.
