Abstract

The invention relates to a gate lock, and is technically characterized in that an insertion member connected to one end of a handle is provided with steel balls, and the other side is provided with a key hole in which a key can be inserted. A spiral slide track and a T-shaped slide track are in moveable fit connection with the steel balls on one end of the handle, namely that when the steel balls on the end of the handle are stressed to slide along the spiral slide track to the terminal end of the slide track, a big spring is stressed; when the big spring is reset, the steel balls are stressed to slide along the spiral slide track to the start end thereof; and the big spring is arranged in a rod cavity of the lock rod, and one end of the big spring is in butted with a handle hole. The key is rotated towards a counterclockwise direction; after the lock is unlocked, the handle is stressed to rotate, and a first pin sheathed in the spiral slide track is rotated from the terminal end of the spiral slide track to the start end thereof along with the rotation direction of the handle; and as the key is interlocked with a steel ball sleeve of a lock core component, the spiral slide track, the T-shaped slide track, the lock rod and a lock bolt, the lock rod drives the lock bolt to rotate. The gate lock has the advantages of reasonable structural design and convenient unlocking or locking, and can be matched with an electric cabinet door and a tool cabinet door.

Description

Door lock

Technical field

The present invention relates to a kind of door lock.

Background technology

At present, the door lock style of selling on the market is more, and constantly has trendy entering the market to select for the customer.This type of technology of patent publication is many, publication number CN101285361A as the Chinese patent literature publication, denomination of invention " a kind of door lock ", this disclosure of the Invention a kind of door lock simple in structure, easy to use and with low cost, comprise: buckle and the locking device that matches with buckle, described locking device comprises lock bracket, offer the bayonet socket that matches with buckle on the lock bracket, also be movably set with clasp that matches with bayonet socket and the operating grip that matches with clasp on the lock bracket, also be provided with the limited block that matches with clasp on the lock bracket.This advantage of inventing described door lock is: structure is very simple, and is with low cost; Easy to operate, durable in use, reliable and stable.The patent on record to this part, the application are not commented in addition.

Summary of the invention

The objective of the invention is provides a kind of door lock to this area, makes its unlatching or locking comparatively convenient, and structure is also uncomplicated.The objective of the invention is to be achieved through the following technical solutions.

A kind of door lock, this door lock comprises that key, handle, big spring, spiral slide are led, T type cunning is led, lock core, locking bar, fixed block, dead bolt, its technical essential is: the inserts that handle one end connects is provided with steel ball, and the another side is provided with the keyhole that inserts for key.The effect of steel ball: the one, play interconnect function, connect handle and fixed block, make handle can not throw off fixed block; The 2nd, play the guiding role, when handle was stressed, steel ball was movable in steel bead groove, makes the stressed rotation of handle.Spiral slide leads that to lead with first pin with T type cunning be to be connected movingly, promptly first pin stressed when the spiral slide slide guide walks to the terminal of slideway big spring stressed; The stressed top that walks to slideway along the spiral slide slide guide of first pin when big spring resets; Described big spring places the bar chamber of locking bar, and one end and handle hole offset.The effect of first pin: spiral slide leads that to lead with first pin with T type cunning be to be connected movingly, i.e. stressed top or the terminal along the spiral slide leading to slideway of first pin rotated thereby drive dead bolt during the stressed rotation of handle.

Described fixed block centre is a through hole, and its end is a thread segment, and this section is connected with O shape circle, big nut.One section through hole that places fixed block of described locking bar, another section of locking bar is a thread segment, this section connects primary nut, grooved metal gasket, dead bolt.

Reasonable in design of the present invention, open or locking comparatively convenient, be applicable to that electric cabinet door, Tool Cabinet door are supporting.

Description of drawings

Fig. 1 is the explosive view of door lock.

Fig. 2 is the profile schematic diagram of door lock assembling.

Fig. 3 is the structural representation of Fig. 2,

Above figure number and title: 1, key, 2, handle, 3, steel ball, 4, big spring, 5, spiral slide is led, and 6, T type cunning leads 7, first pin, 8, lock core, 9, second pin, 10, little spring, 11, the V-type cunning is led, and 12, screw, 13, locking bar, 14, fixed block, 15, O shape circle, 16, big nut, 17, primary nut, 18, grooved metal gasket, 19, dead bolt.

The specific embodiment

Embodiment in conjunction with the accompanying drawings 1～3.Setting Fig. 2 and Fig. 3 is the locking state schematic diagram of door lock, with key 1 to counterclockwise rotate unblank after, turning handle, be enclosed within spiral slide and lead first pin 7 in 5 also along with the direction that handle rotates is led middle activity at spiral slide, the terminal of being led by spiral slide slides to top, because key and lock core assembly (the lock core assembly by lock core 8, second pin 9, little spring 10, V-type cunning lead 11, screw 12 constitutes), steel ball sleeve, spiral slide lead 5, T type cunning leads 6, locking bar 13, dead bolt 19 link, rotate so locking bar just drives dead bolt; Dead bolt is promptly offed normal by the state that is in locking, turns to the non-locking state that is in Fig. 1.The power of locking and non-locking state, a rotatory force by means of handle, two elastic force realizations by spring.The part that other does not relate to as yet, function and effect all belong to known technology, so do not described one by one.
