Spiral tensioning device of air conditioning box access door

Abstract

The invention discloses a spiral tensioning device of an air conditioning box access door. The access door is hinged with a heat-preservation plate of an air conditioner through hinges; the edge of a corresponding access door is provided with an inner door frame; the inner side face of the access door is rotatably provided with a connecting rod through a rotating shaft; the access door is provided with a first limiting sleeve and a second limiting sleeve corresponding the two ends of the connecting rod; the outer side face of the access door is provided with a sliding pin component comprisinga fixed part which is fixed on the access door and a sliding part which can slide along the fixed part; the sliding part can rotate in the direction perpendicular to the surface of the access door; athird limiting sleeve is arranged on the outer side of the heat-preservation plate; the sliding part is inserted into the third limiting sleeve; the connecting rod in the second limiting sleeve is provided with a first nut; the sliding part is provided with a second nut; the access door is provided with a through hole which is perpendicular to the surface of the access door; and a bolt is matchedin the second nut, and is matched in the first nut after passing through the through hole, so that the access door is tensioned on the inner door frame. The spiral tensioning device has a simple structure, is easy to implement, is reliable in tensioning effect and is suitable for popularization and use.

Description

Technical field [0001] The invention involves a type of air -conditioning box inspection door, which specializes in a type of air -conditioned box inspection door spiral tightening device. Background technique [0002] The air -conditioning box maintenance doors in the existing technologies are only one side (usually one side that can be opened) can be tightened on the inside frame. When the inspection door is in the positive pressure section, the side that is not tightened is not tightened.The phenomenon of leakage will cause air -conditioning boxes to not be closed, which not only reduces energy efficiency, but also has hidden safety hazards, causing losses to users. Invention content [0003] The purpose of the present invention is to provide a spiral device that can tighten both sides of the air -conditioning box inspection door. [0004] In order to solve the above technical problems, the present invention uses the following technical solutions: [0005] An air -conditioned...

Problems solved by technology

[0002] The inspection door of the air conditioning box in the prior art has only one side (usually the side that can be opened) that can be tightened on the inner frame of the door. When the door is in the positive pressure section, air leakage will occur on the side that is not tightened, causing the air-conditioning box to not be airtight, which not only reduces energy efficiency, but also has potential safety hazards, causing losses to users
