Problems solved by technology

The technical disadvantages of the latch in the existing market are: the locking plate of the latch adopts an eccentric wheel structure, the lock body adopts a sheet metal structure, and the lock core shaft is welded on the side of the gate. The mandrel hits the lock plate repeatedly. Under the action of the reaction force, the lock plate easily jumps up and rests on the upper side of the lock mandrel, losing its blocking effect on the lock mandrel, which in turn causes the lock mandrel to slide out of the lock body, causing the gate to lose its Locked and opened, eventually causing the pigs to escape the pen

Abstract

The pigsty latch with a labyrinth type one-way switch of the present invention comprises a lock case, a lock core and a lock plate, one end of the lock case is provided with an opening, and its non-open end is fixed on the door frame, and the lock core includes a lock Core fixing block, labyrinth slider, locking hook, spring, the lock core fixing block is fixed on the inner side of the lock case, the labyrinth slider is provided with an engaging part A and a labyrinth part, and the labyrinth The slider is slidably arranged on the lock cylinder fixing block, and the associated locking hook is slidably arranged on the labyrinth part of the labyrinth slider. With engaging part B. The beneficial effects of the present invention are: adopting the labyrinth locking method to realize the locking and one-way opening of the lock plate, and the latch cannot be opened when hitting the fence door from the other side, which effectively solves the problem of pigs hitting the fence door and escaping from the pigsty. question.

Description

technical field [0001] The invention relates to a lock, in particular to a pigsty latch with a labyrinth type one-way switch in the pig breeding industry. Background technique [0002] In order to meet the needs of large-scale pig raising, most pig farms use various stall equipment according to the requirements of standardized pig farms, including farrowing beds for sows, positioning pens, and nursery pens for piglets. Its purpose is to effectively limit the management of pigs and prevent pigs from fleeing. The locking devices for the gates on various stalls have become the top priority. The quality of latches on the existing market is uneven, and pigs escape from arches during the breeding process. The technical disadvantages of the latch in the existing market are: the locking plate of the latch adopts an eccentric wheel structure, the lock body adopts a sheet metal structure, and the lock core shaft is welded on the side of the gate. The mandrel hits the lock plate rep...
