Description

Technical Field

[0001] The utility model relates to the technical field of exhaust equipment, in particular to an intelligent temperature-controlled strong exhaust fan for a cabinet. Background Art

[0002] A cabinet is an independent or self-supporting housing for electrical or electronic equipment. It is the carrier of electrical control equipment and is generally made of cold-rolled steel plates or alloys. It can provide waterproof, dustproof, and electromagnetic interference protection for the stored equipment. Since the electronic equipment in the cabinet will generate heat during operation, in order to protect the equipment, existing cabinets are usually equipped with exhaust fans for ventilation and heat dissipation. Most existing intelligent exhaust fans have the function of automatic temperature control and can control the exhaust intensity according to the temperature in the cabinet.

[0003] The shell cross-section of existing cabinet intelligent temperature control forced exhaust fans is mostly composed of two rectangles with a larger upper part and a smaller lower part. The exhaust fan shell is inserted into the mounting slot on the top of the cabinet, so that the exhaust fan is stuck inside the mounting slot. However, since there is no fixed structure inside the cabinet, the exhaust fan is prone to shake up and down when the cabinet shakes, resulting in the risk of dislocation of the exhaust fan, which reduces the ventilation effect.

[0029] Among them, a connecting plate 203a is fixedly connected to the inner side of the clamping plate 203, and an elliptical rotating block 203b is provided on the other side of the connecting plate 203a. The eccentric part of the elliptical rotating block 203b is rotatably connected to the inside of the exhaust fan housing 201 through a rotating shaft. The elliptical rotating block 203b pushes the connecting plate 203a to move as it rotates, thereby pushing the clamping plate 203 to move and get stuck in the exhaust fan mounting slot 102.

[0030] Furthermore, a spring 203c is fixedly connected to the inner side of the connecting plate 203a, and the other end of the spring 203c is fixedly connected to the inner wall of the exhaust fan housing 201.

[0031] Furthermore, the inner wall of the exhaust fan housing 201 is fixedly connected to a limit plate 201a, and a rotating rod 201b is fixedly connected to the rotation center of the elliptical rotating block 203b. The rotating rod 201b overlaps the bottom of the limit plate 201a, and the rotation range of the rotating rod 201b is limited by the limit plate 201a, thereby preventing the elliptical rotating block 203b from rotating too much.

[0032] Furthermore, the driving assembly 202 includes an active rotating shaft 202a, the bottom end of the active rotating shaft 202a is fixedly connected to a bevel gear 1 202b, the lower part of the bevel gear 1 202b is meshingly connected to a bevel gear 2 202c, the bevel gear 2 202c is fixedly connected to the rotating shaft at the rotation center of the elliptical rotating block 203b, and the active rotating shaft 202a drives the bevel gear 2 202c to rotate through the bevel gear 1 202b, thereby driving the rotating shaft and the elliptical rotating block 203b to rotate.

[0033] Furthermore, a knob 202d is fixedly connected to the top of the active rotating shaft 202a, a fixing hole 202e is provided on the top of the knob 202d and passes through the top and bottom, a connecting hole of the same size is provided on the top of the exhaust fan housing 201, and the fixing hole 202e and the connecting hole are connected by bolts to prevent the knob 202d from rotating autonomously.

[0034] During use, the bolt is removed from the fixing hole 202e, and then the active rotating shaft 202a is driven to rotate through the knob 202d, and the elliptical rotating block 203b is driven to rotate through the bevel gear 1 202b and the bevel gear 2 202c, and the connecting plate 203a and the card plate 203 are reset through the spring 203c, so that the card plate 203 is retracted to the inner wall of the exhaust fan casing 201, thereby facilitating the disassembly, maintenance or replacement of the exhaust fan casing 201. The exhaust fan casing 201 can be installed in the exhaust fan mounting groove 102 by the reverse operation, and the longitudinal position of the exhaust fan casing 201 is fixed by popping the card plate 203 outward and clamping it inside the exhaust fan mounting groove 102, thereby preventing the exhaust fan casing 201 from shaking up and down and causing the exhaust fan casing 201 to be misaligned, thereby improving the ventilation effect.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
