Abstract
The invention discloses a three shaft sleeve blocking type lock, which comprises a shell and a lock cylinder inside the shell. The lock cylinder comprises a circular fixed shaft sleeve, an inner shaft sleeve and an outer shaft sleeve. A key is inserted from front ends of central holes of the circular fixed shaft sleeve, the inner shaft sleeve and the outer shaft sleeve sleeved together. A square chamber is arranged inside the shell. More than one blocking sheet grooves are vertically arranged on chamber walls on both sides at intervals. A hook-shaped locking plate which controls a circular outer shaft sleeve to rotate and a corresponding spring are respectively arranged in each blocking sheet groove. The lock with a structure and a key structure are simple in structure and low in cost. Repeatability of keys is greatly reduced due to match of a key rod and the circular inner shaft sleeve, match of a positioning frame and tooth width and opening grooves of the lock cylinder and the key, match of a key positioning block and the positioning frame on the key, as well as match of number of teeth and height of the key teeth and hook-shaped locking plates and an arc-shaped edge. The lock cylinder is mutually locked with a blocking groove through blocking heads of the hook-shaped locking plates, so that an anti-twisting capacity is strong. The three shaft sleeve blocking lock is suitable for cabinet locks, door locks and vehicle locks and the like.
Description
Technical field
The present invention relates to a kind of lock, especially anti-theft cylinder lock.
Background technology
Cylinder lock is traditional theftproof lock, and it is simple with structural principle, cost is low, easy to use and have anti-theft effect and be widely used, and to the country and people's property, positive effect has been played in antitheft and protection.Cylinder lock is mainly can to block by rotation cores by cylindricality pellet, and reaches the object of lock; And each cylindricality pellet whether block be that key tooth by corresponding with pellet is controlled and unblanks.Along with social development, the theftproof performance of existing this anti-theft cylinder lock declines greatly, is easy to be twisted off by force cylindricality pellet, and rotation can rotation cores and unblanked.And the control of cylindricality pellet only has by the length of corresponding key tooth and controls, the repeatability of key is large, is easy to copy, and causes burglary to increase, and shape is rung the stable of society.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, cost is low and theftproof good, and three little axle sleeve cassettes locks of the repeatability of key.
For reaching above-mentioned purpose, technical scheme of the present invention is:
A kind of three axle sleeve cassette locks, it comprises the lock core in housing and housing, it is characterized in that:
Described lock core comprises by circular dead axle cover, circular internal axle sleeve and circular outer shaft, wherein, one side of circular dead axle cover is fixedly connected with post dot structure and housing inner side, and circular internal axle sleeve is enclosed within circular dead axle cover, and circular outer shaft is enclosed within circular dead axle cover outside; The rear end of circular internal axle sleeve and circular outer shaft is all fixedly connected with square spigot, and key inserts from the centre bore front end of the circular dead axle cover being nested together, circular internal axle sleeve and circular outer shaft;
The inner side of described housing is rectangular cavity, and on adjacent chamber, the both sides wall in inner side, longitudinal separation is provided with one or more some card slot, is respectively equipped with and controls hook shape locking plate and the corresponding spring thereof that described circular outer shaft rotates in each card slot.
In one side of described circular dead axle cover, circular internal axle sleeve and circular outer shaft, be all provided with the key open slot that can align, key drives circular internal axle sleeve and circular outer shaft to rotate by key open slot.
Described circular dead axle is enclosed within front end and two places, rear end of the same side, to be fixedly connected in the structure of pin deck and housing.
Described circular dead axle is enclosed within a side of key open slot by the isolation channel at two intervals, is provided with key and cooperatively interacts, the arc key locating piece that key can be rotated.
On described circular outer shaft with the perpendicular side of key open slot on, be provided with one with hook the corresponding screens groove blocking mutually of shape locking plate, and, in the rear end of this screens groove, be also provided with the be fixedly connected slot to make way of pin deck of vertical with it circular dead axle cover and housing.
There is the arc-shaped side of a concavity inner side, middle part of described hook shape locking plate, corresponding with corresponding key key bit; Hook shape locking plate below for can insert the dop in described circular outer shaft screens groove.
A key for three axle sleeve cassette locks, comprises the shank of the key and the spoon bar being fixedly connected with the shank of the key, it is characterized in that:
In a side of described spoon bar, be fixedly connected with a posting with the mutual corresponding matching of described arc key locating piece, in the outside of posting, be provided with more than one some key bits.
The number of teeth of described key key bit and height are corresponding with described hook shape locking plate and arc-shaped side thereof.
Three axle sleeve cassettes of above structure are locked and key structure is simple and cost is low, only be included in the key open slot of key in a side of circular dead axle cover and circular internal axle sleeve and circular outer shaft, circular dead axle put the number of teeth of posting on key locating piece and key and key key bit and highly with described hook shape locking plate and the mutual corresponding matching of arc-shaped side thereof, just can make key bit on key back down in rotation to hook shape locking plate to be stuck in the dop in circular outer shaft screens groove, and can be rotated further the circular internal axle sleeve of drive and the rotation of circular outer shaft, the square spigot being fixedly connected at circular internal axle sleeve and circular outer shaft follower head rotates thereupon.The rotation of square spigot can drive locking bolt or dead bolt to move by driving member and unblank.Due to the selection that has the number of teeth of the coordinating of the coordinating of the coordinating of spoon bar and circular internal axle sleeve endoporus, posting and key bit width thereof and lock core key open slot, key locating piece and posting on key, key key bit and height to coordinate with described hook shape locking plate and arc-shaped side thereof, greatly reduced the repeatability of key, be also difficult to imitated.And, lock core be that dop and circular outer shaft screens groove by some hook shape locking plates blocks to lock mutually, can bear very large twisting resistance, uprising turning round.Greatly improved theftproof performance.
