Embodiment Construction

[0009] Such as figure 1 As shown, in the present invention, a bolt 2 is connected to the middle part of the lower plane of the hexagonal screw head 1, and an annular groove 3 is arranged around the joint between the hexagonal screw head 1 and the bolt 2, and the waterproof skirt 4 is arranged on the hexagonal screw head. On the lower side of the outer periphery of 1, the nut 5 is screwed on the bolt 2, the upper plane of the nut 5 is an inclined surface 6, and the inclined surface 6 on the nut 5 is matched with the annular groove 3. Through the above settings, the present invention punches holes at the edge of the overlapping ceiling plastic plates when connecting the ceiling plastic plates, inserts the bolt 2 in the hole, the nut 5 is screwed on the bolt 2, and the nut 5 is locked, and the nut 5 is locked Simultaneously, the edge of the hole on the ceiling plastic plate is squeezed into the annular groove 3 on the hexagonal screw head 1 by the inclined surface 6 on the nut 5,...

Abstract

The invention discloses a novel waterproof bolt. The novel waterproof bolt is characterized in that a bolt is connected to the middle part of a lower plane of a hexagonal screw head; an annular groove is formed around the connecting place between the hexagonal screw head and the bolt; a waterproof skirt edge is arranged on the lower side of the outer periphery of the hexagonal screw head; a nut is tightened on the bolt; the upper plane of the nut is an inclined surface; and the inclined surface of the nut is matched with the annular groove. Through the settings, the novel waterproof bolt is applied to fixed connection of a ceiling plastic plate, can effectively achieve a waterproof effect, is convenient for installation and use, improves the installation working efficiency, and prolongs the service life of a workshop ceiling.

Description

technical field [0001] The invention relates to a bolt, in particular to a bolt with waterproof function. Background technique [0002] With the development of the times, plastic ceilings are used in steel structure workshops. The existing bolts used to connect and fix the plastic panels on the ceiling do not have waterproof functions, which often cause water leakage. It is necessary to add a rubber waterproof gasket under the screw head of the bolt to achieve the waterproof function, which is not convenient for installation and use. Contents of the invention [0003] The object of the present invention is to provide a novel waterproof bolt for connecting and fixing plastic ceilings. [0004] In order to achieve the above object, in the present invention, a bolt is connected to the middle part of the lower plane of the hexagonal screw head, an annular groove is arranged around the connection between the hexagonal screw head and the bolt, and the waterproof skirt is arrang...
