Description

Technical Field

[0001] The utility model relates to the technical field of door latches and door locks for pasture fences, in particular to an automatic latch door lock for pasture fences. Background Art

[0002] Many herdsmen on the grassland use primitive methods to lock their fence gates, such as using cloth ropes to tie the fence gates and door posts together, or using iron wire to tie the fence gates and door posts together.

[0003] Now we analyze the problems existing in actual work when using cloth ropes and wires for tying:

[0004] Use cloth ropes to tie: Cloth ropes are exposed to the outside for a long time and are easily weathered by wind erosion. Therefore, this method of tying is not strong. Once cattle and sheep get close and rub against the fence door, the cloth ropes can easily break.

[0005] Using wire to tie: After the wire is tied, the knot becomes sharp and can easily scratch or prick your hands. In addition, the wire can easily break after being tied back and forth for a long time.

[0006] Therefore, based on the above-mentioned actual situation, the inventor now proposes an automatic latch door lock for a pasture fence. Utility Model Content
