Special both-way door lock device for pigpen door

Abstract

The invention discloses a special both-way door lock device for a pigpen door. The special both-way door lock device comprises a pigpen door outer cylinder handle, a pigpen door inner hexagonal handle, a semicircular double-bending sheet, an outer protruding plate, an outer fixing steel plate, an inner fixing steel plate, a long-strip-shaped door bolt, a buckling nose, a vertical-strip-shaped fixing steel plate and a movable buckle. The outer protruding plate and the outer fixing steel plate are welded together. The pigpen door outer cylinder handle is in an L shape, a short arm of the cylinder handle penetrates a circular hole in the outer protruding plate to be vertically welded to the semicircular double-bending sheet, and a short arm of the pigpen door inner hexagonal handle penetratesthe inner fixing steel plate and the movable buckle and then is inserted and connected in a regular hexagon hole in one side of the semicircular double-bending sheet. One end of the long-strip-shapeddoor bolt falls into a chamfer on the inner side of the upper end of the buckling nose, and the other end of the long-strip-shaped door bolt can rotate up and down along a hinged bolt. The special both-way door lock device is reasonable in design, unique in structure and convenient to machine and is used for the pigpen door needing to be frequently opened and closed, the special both-way door lock device is simple, durable, resistant to corrosion, not prone to damage and capable of being opened and closed in both directions from the interior and the exterior of the pigpen door.

Description

Technical field: [0001] The invention relates to a door lock device, in particular to a special two-way door lock device for pig house doors, which is used on house doors that need to be opened and closed frequently, and can be opened from both inside and outside. Background technique: [0002] In large-scale pig farms, a large number of pig house doors need to be installed with a durable, water-resistant and corrosion-resistant door lock that can be opened from inside and outside. Simple latch locks are strong and durable, but they don't open and close in both directions. Most of the door locks on the market now use a lock cylinder and lock tongue structure. After a long time, the lock cylinder is easy to rust and cause the door lock to fail. Once the door lock fails and is not closed tightly, the cold will leak into the pig house in winter, causing cold stress in the pig herd, which will bring economic losses to the breeding enterprise.
