The invention discloses a hydraulic remote-control password lock, comprising a lock body, a lock element and a bolt, wherein, the lock element is in the lock body. The invention is characterized in that the lock element is longitudinal arranged with a guide groove, with two grooves of lock body to form a bended oil channel via joint; the bolt and the lock body are separated mounted; the lock body and the bolt have a hydraulic controller formed by a plug hydraulic cylinder, an oil tube and a bolt operating cylinder between them; the upper end of the piston of plug hydraulic cylinder is hinged to the inner end of the operating axle via crank; the connecting oil tubes are arranged between the oil inlet of lock body and the oil outlet of plug hydraulic cylinder, between the oil outlet of lock body and the oil inlet of bolt operating cylinder; the outer end of the piston of bolt operating cylinder is relative to the pushing plate fixed on the back end of bolt. The invention has wide application, high reliability, and simple password change, with remote control.
Description
Technical field: [0001] The invention relates to a combination lock, in particular to a hydraulic remote control combination lock. Background technique: [0002] At present, there are many kinds of combination locks, most of which are divided into two categories. One is electronic combination locks, which often cause electrical components to burn out and short circuits to cause damage to combination locks; the other is mechanical combination locks. This kind of combination lock has poor anti-break performance, and it is troublesome to unlock. It is necessary to align each scale under the situation of sufficient light to open the lock, and it is not very convenient to change the combination lock. These two combination locks are mainly used in some safes, doors, bicycles or motorcycles, but are not practical for large-scale cars. In view of this situation, Chinese Patent No. 200420068073.6 discloses a kind of "combined oil lock". This kind of oil circuit combination lock inc...
