Description

Dustproof cover piece of manual-automatic integrated door closer Technical Field The utility model relates to the technical field of door closer dust cover parts, in particular to a dust cover part of an automatic-manual door closer. Background The door closer is characterized in that the door closer is formed by combining a metal spring and a hydraulic damping function to achieve a buffering function, when the door is opened, the door can be released after being compressed, the door is automatically closed, the door can be accurately and timely closed to an initial position after being opened, and the dust cover part is a component part of the automatic door closer and is a sealing buffering part arranged between the panel and the output shaft. When the existing door closer dust cover piece is in actual use, the dust cover piece is embedded and installed on the panel, the installation operation is inconvenient, a buffer structure is absent between the dust cover piece and the cover plate, the dust cover piece is easy to damage due to external force such as trampling or foreign matter impact, and the problem is solved by the dust cover piece of the manual-automatic door closer. Disclosure of utility model Aiming at the defects and defects in the prior art, the utility model provides a dustproof cover piece of a manual-automatic door closer, which is used for solving the technical problems that the dustproof cover piece of the existing door closer is embedded and installed on a panel in actual use in the prior art, the installation operation is inconvenient, a buffer structure is absent between the dustproof cover piece and the cover plate, and the dustproof cover piece is easy to damage due to external force such as treading or foreign body impact. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a dustproof cover piece of manual-automatic door closer, includes no lid box body and door closer body, door closer body fixed mounting is in no lid box body, be equipped with the guide shaft on the door closer body, the upper end fixed mounting of no lid box body has the panel, the upper end of panel is equipped with circular shield, the vertical activity of guide shaft runs through panel and circular shield setting, the lower extreme of circular shield and the upper end activity joint of panel. Preferably, the upper end of the panel is provided with an annular bulge and four arc bulges, the guide shaft is arranged on the inner side of the annular bulge, the four arc bulges are distributed in a cross shape, and the lower end of the circular dust cover is pressed against the annular bulge and the upper ends of the four arc bulges. Preferably, the upper end of circular shield central point puts and is equipped with circular opening, the vertical circular opening that runs through of guide shaft sets up, fixedly connected with ring seal on the annular inner wall of circular opening, ring seal's annular inner wall and the annular lateral wall sliding counterbalance contact of guide shaft.
