Abstract
The invention belongs to the technical field of locks, and particularly relates to a mechanical-password two-prevention lock specially used for locking a locking rod through an anti-explosion electrical switch of a coal mine. The mechanical-password two-prevention lock mainly solves the technical problem that an existing two-prevention lock cannot guarantee that an electrical device is operated by a specially-assigned person, and therefore the accident potential is brought for underground safety production of the coal mine. According to the technical scheme, the mechanical-password two-prevention lock comprises a fixed lock catch, a movable lock catch, two fixing bolts and a hinge pin. The mechanical-password two-prevention lock further comprises a lock body, a spring, a push-pull positioning pin, n password sleeves, n-1 password changing sleeves, n steel balls and an outer casing pipe. The mechanical-password two-prevention lock has the advantages that passwords are not prone to decoding, the safety performance is high, the structure is simple, use is convenient, and the number of password combinations is large.
Description
Technical field
The invention belongs to lock technology field, be specifically related to a kind of mechanical cipher two that is exclusively used in coal mine explosion-proof electric switch locking deadlock lever anti-lock.
Background technology
At present, in Safety of Coal Mine Production, operation to downhole anti-explosion electric fixtures is more and more stricter, < < safety regulations in coal mine > > regulation: under coal mine, the mechanical latching bar of electric apparatus for explosive atmospheres must be installed and prevent other people power transmission, the operation that prevents from uncapping without authorization two anti-lock without authorization, is used for guaranteeing that special messenger operates the reliability of electric fixtures.Existing two anti-lock keys are general, only that is to say and just can open the two all anti-lock electric fixturess that operate with a key, do not have the effect that special messenger operates electric fixtures, so just to safety in production under coal mine, bring accident potential.
Summary of the invention
Thereby the object of the invention is to solve existing two anti-being latched in, do not have the effect that special messenger operates electric fixtures and to safety in production under coal mine, bring the technical problem of accident potential, provide a kind of mechanical cipher two anti-lock.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of mechanical cipher two is anti-lock, comprises quiet snap close, moving snap close, two set bolts and bearing pin, wherein: it also comprises, and lock body, spring, push-and-pull alignment pin, a n password cover, n-1 change that code overlaps, a n steel ball and outer tube; described spring is arranged on the left end of lock body inner chamber, bearing pin is arranged in the inner chamber of lock body and the left end of bearing pin and the right-hand member of spring is contacted, the lower end of push-and-pull alignment pin is connected with the sidewall of bearing pin left end and can in the pin-and-hole of gap, moves left and right and drive bearing pin to move left and right in the inner chamber of lock body through the pin-and-hole in lock body gap, n steel ball is arranged in the equidistant n offering a steel ball hole, lock body sidewall middle part and is positioned at the equidistant n offering a bearing pin steel ball hole, bearing pin sidewall middle part, n password cover is sleeved on the middle part of lock body and is positioned at the outside of n steel ball, the inner side of n password cover is provided with password cover steel ball hole, n-1 changes code and is sleeved on lock body and between n password cover, outer tube is sleeved on the right of lock body and is positioned at the right side of last password cover, the left end of quiet snap close is connected with the right-hand member of outer tube and makes the dead bolt of bearing pin right-hand member be positioned at the bayonet socket that quiet snap close and moving snap close form, the left end of moving snap close is connected with the right-hand member of quiet snap close by two set bolts to be fixed on locking screw rod mechanical cipher two is anti-lock.
The hole depth in hole depth+lock body steel ball hole in diameter=bearing pin steel ball hole of described steel ball; Described password cover steel ball hole hole depth equates with bearing pin steel ball hole hole depth
The present invention adopts above technical scheme, thereby solved existing two anti-being latched in, does not have the effect that special messenger operates electric fixtures and to safety in production under coal mine, brings the technical problem of accident potential.Therefore, compare the advantage such as the present invention has that password is difficult for cracking, security performance is high, simple in structure, easy to use and password combination quantity is large with background technology.
