Description

Technical Field

[0001] The utility model belongs to the technical field of cross-flow fans, and particularly relates to a fixing frame structure for fixing a cross-flow fan. Background Technique

[0002] The cross-flow fan is also called a transverse flow fan. The cross-flow fan mainly consists of an impeller, an air duct and a motor. The impeller material is generally aluminum alloy or engineering plastic. The aluminum alloy impeller has high strength, light weight and high temperature resistance, and can maintain long-term stable operation without deformation; the plastic impeller is injection molded by a mold and then welded by ultrasonic waves, and is generally used in occasions with lower rotational speeds and larger diameters.

[0003] In the prior art, the fixing frame structure of the cross-flow fan is generally relatively simple, which is not convenient for later installation and disassembly. At the same time, the existing fixing frame has a single function, resulting in poor practicability of the device and inconvenience for later use. Content of the Utility Model

The circumferential sides of the two positioning rods are in sliding fit with the positioning plates. Pad plates are embedded on the circumferential sides of the two positioning rods, which is convenient for the installation and disassembly between the positioning plate and the cross-flow fan, thereby facilitating the later maintenance and replacement of the cross-flow fan and improving the flexibility of the device during use.

[0007] Furthermore, the two pad plates are welded to one surface of the positioning plate. The circumferential sides of the two positioning rods are in sliding fit with the pad plates. The other ends of the two positioning rods are welded with pulling plates.

[0008] Furthermore, connecting springs are welded between one surface of each of the two pulling plates and one surface of each of the two pad plates. The two connecting springs are respectively wound around the circumferential sides of the two positioning rods.

An impeller is installed on the circumferential side surface of the coupling shaft. A drive shaft is installed on one surface of the cross-flow fan mounting frame.

[0010] Further, one end of the drive shaft penetrates through one surface of the cross-flow fan mounting frame. One end of the drive shaft is cooperated with the coupling shaft. A drive motor is installed on the other end of the drive shaft.

[0011] Further, side plates are welded on the upper surfaces of the two positioning plates. The two side plates are in an "L"-shaped plate structure. One ends of the two side plates are welded with a fixing plate. The fixing plate is in an "L"-shaped plate structure. Two fixing bolts are installed on one end of the fixing plate. The two fixing bolts are arranged oppositely.

[0012] Further, one ends of the two fixing bolts penetrate through one surface of the fixing plate. An installation groove is arranged on one surface of one side plate. A heat dissipation box is installed inside the installation groove. A heat dissipation fan is installed inside the heat dissipation box.

[0013] Further, a plurality of heat dissipation grooves are arranged on two opposite surfaces of the heat dissipation box. The heat dissipation fan is cooperated with the drive motor through the heat dissipation grooves, which is convenient for properly dissipating heat from the drive motor, avoiding the temperature of the drive motor being too high, improving the functionality of the fixing structure during use, and facilitating later use.

[0014] The utility model has the following beneficial effects:

[0015] Through the positioning rod and connecting spring structure of the utility model, the installation and disassembly between the positioning plate and the cross-flow fan are convenient, so as to facilitate the later maintenance and replacement of the cross-flow fan, and improve the flexibility of the device during use.

[0016] Through the heat dissipation box and heat dissipation fan structure of the utility model, it is convenient to properly dissipate heat from the drive motor, avoid the temperature of the drive motor being too high, improve the functionality of the fixing structure during use, and facilitate later use.
