A positioning sleeve

Abstract

The invention discloses a positioning sleeve, which is fixedly arranged on the floor of a clean room. A plurality of ventilation holes are formed on the floor of the clean room. The ventilation holes are covered with a ventilation plate, and counterbores are formed on the upper edge of the ventilation holes. The step, the socket fits in the counterbore step to carry the ventilation panel. The sleeve is formed according to the size of the counterbore step on the ventilation hole. When the sleeve is placed, it matches with the counterbore step, and then the ventilation plate is smoothly set on the sleeve, which improves the stability of the ventilation plate. Since the building structure of the clean room floor is mostly made of non-conductive materials, the static system in the room can be effectively controlled by setting the sleeve, and at the same time, the contact and collision between the ventilation plate and the floor can be avoided when placed. By setting the adjusting gasket and the elastic pressing piece, on the one hand, the contact force between the ventilation plate and the sleeve can be buffered, the damage to the surface coating of the ventilation plate can be reduced, and the antistatic performance of the ventilation plate can be guaranteed. On the other hand, the pre-tightening positioning of the ventilation plate can be realized to ensure the stability of the installation of the ventilation plate.

Description

technical field [0001] The invention belongs to the technical field of using a clean room floor, and in particular relates to a positioning sleeve arranged on a clean room floor. Background technique [0002] In recent years, with the rapid development of my country's high-tech electronics, biopharmaceutical and other industries, newly-built workshops with cleanliness requirements have gradually increased. In order to ensure the cleanliness of the air in large-scale production workshops, it is necessary to establish a clean air-conditioning and ventilation system, which is usually required in the workshop building. A large number of holes are evenly reserved in the cover to form a return air channel. In order to meet the requirements of high clean space, it adopts the air organization form of vertical flow, that is, many regular holes are reserved on the floor of the clean workshop to circulate the air inside and outside the clean room, and the air treatment system is used to...

AI Technical Summary

Problems solved by technology

At present, during the production process of the waffle plate, there may be unevenness in the hole, and the ventilation plate often shakes after being covered on it, and the ventilation plate will collide with the waffle plate when it is placed, so that It will cause damage to the surface coating of the ventilation panel and affect the antistatic performance of the ventilation panel
