Description

Technical Field

[0001] The invention relates to the technical field of exhaust fan maintenance and installation, and in particular to a component-type top exhaust fan maintenance port sealing plate installation structure. Background Art

[0002] Existing exhaust fans are a type of air conditioning appliance that uses a motor to drive the blades to rotate and drive the air flow to exchange indoor and outdoor air. The purpose of exhaust is to remove the dirty air in the room and adjust the temperature, humidity and sensory effect. Exhaust fans are widely used in homes and public places. The use environment of exhaust fans is generally used in some occasions that require low noise and high static pressure to achieve an air circulation effect. Different exhaust fans have different voltages and size specifications. When choosing, users can choose different types of exhaust fans according to their different needs. Before installing the exhaust fan, it is necessary to determine an installation position. The confirmation of this position needs to pay attention to the use environment and see which specific installation is most appropriate, so that the exhaust fan can achieve the best use effect.

[0003] In the prior art, when an exhaust fan fails, the sealing plate of the inspection port needs to be disassembled so that the operator can perform fault inspection on the exhaust fan through the inspection port. However, the existing sealing plate lacks a mechanism for easy disassembly and installation during disassembly or installation, thereby reducing the maintenance efficiency of the operator.

[0004] At the same time, exhaust fans are usually installed in relatively closed indoor environments such as bathrooms. Therefore, once the lighting in relatively closed indoor environments such as bathrooms fails to illuminate, the indoor visibility will be extremely low, thereby posing a safety hazard of people accidentally falling indoors. For this reason, a component-type top exhaust fan inspection port sealing plate installation structure is proposed. Summary of the invention

[0005] The object of the present invention is to provide a modular top exhaust fan inspection port sealing plate installation structure to solve the problems raised in the above-mentioned background technology.

[0009] As a further preferred embodiment of the technical solution: a rod body is welded to the inner side wall of the first slot body, and one end of the rod body away from the first slot body is rotatably connected to the other side of the worm gear.

[0010] As a further preferred embodiment of the technical solution: four fixing plates are welded on the top of the plate body, and a second groove body is opened inside the four fixing plates.

[0011] As a further preferred embodiment of the technical solution: the bottom of the second trough body is communicated with the inner cavity of the first trough body, and a stopper is welded on one end of the worm away from the fixed block.

[0012] As a further preferred embodiment of the technical solution: two support plates are welded to the outer side of the plate body, and thread grooves are provided inside the two support plates.

[0013] As a further preferred embodiment of the present technical solution: a fourth slot body is provided inside the plate body and on the other side of the third slot body.

[0014] As a further preferred embodiment of the present technical solution: two first springs are symmetrically welded to the inner side wall of the fourth slot body.

[0015] As a further preferred embodiment of the technical solution: a clamping block is welded to one end of the two first springs away from the fourth slot body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1.

[0018] 2. The present invention arranges a worm wheel and a worm so that the worm wheel can drive the connecting rod to rotate under the action of the worm, so that the connecting rod can adjust the direction of the lighting lamp through the support rod. Therefore, when the lighting lamp in a relatively closed indoor environment such as a bathroom fails to illuminate, the lighting lamp provided by the installation structure can illuminate all angles of the room, eliminating the safety hazard of people accidentally falling indoors.
