Abstract

The utility model relates to a novel lock for guarding against theft. Five lock ball holding grooves are formed in a lock core along four sides of a key hole, notches of the lock ball holding grooves are communicated with the key hole, a spring and a lock ball are inserted in each lock ball holding groove in sequence, a rib protrudes from the cylindrical surface of each lock ball, when the lock ball is inserted in the holding groove, the rib of the lock ball protrudes into the key hole from the notch; a lock ball clamp seat is fixed at the middle of the bottom of the inside of a lock shell. The novel lock is capable of preventing the phenomenon that the lock is difficult to open normally or cannot be opened due to the lock ball abrasion, and moreover, the novel lock is stable in work and convenient to manufacture, and the novel lock can be opened or locked smoothly.

Description

A kind of novel lock

Technical field

The utility model relates to a kind of novel lock, specifically a kind of easily manufactured, use safe latch lock.

Background technology

On existing market, that locks is of a great variety, main minute two large classes first are electronic locks, the secondth, mechanical lock, generally electronic lock is wanted the normal operation of electric power supply ability than the high still electronic lock of mechanical lock in encryption complexity, and just there is not this shortcoming in mechanical lock, and it has working stability, the advantages such as manufacturing price is low, at general security requirements, mechanical lock just can meet people's needs, but mechanical lock is lock core in long-term use, lock pearl, key all can have wearing and tearing, after particularly locking pearl wearing and tearing, to the normal unlatching of lock, all can bring difficulty, can there is opening phenomenon inconvenient or that do not open at preparation standby key in this abrasion deviation, will make troubles for people's life like this.

Utility model content

The purpose of this utility model is to provide a kind of novel lock, and it can prevent the phenomenon of normally opening difficulty or not opening because of the lock that lock pearl wearing and tearing occur, and working stability, unlatching or lock operation process easily manufactured, that lock are smooth and easy.

Technical solution of the present utility model is at key, lock core, spring, lock pearl, lock housing, on the basis of snap ring, be characterized in round keyhole, being provided with five lock pearl mounting grooves around on lock core, the notch of described lock pearl mounting groove communicates with keyhole, and five springs and five lock pearls are in turn inserted into respectively in lock pearl mounting groove, face of cylinder projection on lock pearl has a muscle, and when lock pearl inserts mounting groove, its muscle projects in keyhole from notch; At the bottom of portion in described lock housing, middle is fixed with lock pearl deck.

The muscle of above-described lock pearl projection, the length of its Length Ratio lock pearl is short, and the length of each muscle is unequal, and between muscle and muscle, length differs minimum for 0.7mm, is 3.5mm to the maximum.

Operating principle of the present utility model is when spring correctly inserts in lock core with lock pearl, the natural tension force of spring protrudes into the part top of lock pearl outside lock core, then lock core is inserted in lock housing, the part that lock pearl protrudes into outside lock core will be inserted in the lock pearl deck in lock housing, lock core can not be rotated in lock housing, if use correct key to insert keyhole, push hard lock pearl and make spring contraction, the part that lock pearl protrudes into outside lock core will be extracted the lock pearl deck in lock housing, at this moment turn just energy opening door lock of key band movable lock core, because length is inconsistent separately for five muscle on lock pearl, not that correct key is while being inserted in lock core, there will be when that root lock pearl of the longest muscle makes spring make maximum compression, that root lock pearl of the shortest muscle to the compression distance of spring also deficiency make to lock pearl and extract completely in lock pearl deck, thereby lock core cannot rotate, lock can not normally be opened, this lock pearl opening ways there will not be the phenomenon that lock can not be opened because of abrasion deviation completely.

The utility model has the advantages that it can prevent the phenomenon of normally opening difficulty or not opening because of the lock that lock pearl wearing and tearing occur, and working stability, unlatching or lock operation process easily manufactured, that lock are smooth and easy.

The specific embodiment

Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the utility model is at key 1, lock core 4, spring 5, lock pearl 6, lock housing 2, on the basis of snap ring 3, be characterized in round keyhole, being provided with five lock pearl mounting grooves around on lock core 4, the notch of described lock pearl mounting groove communicates with keyhole, article five, spring and five lock pearls are in turn inserted into respectively in lock pearl mounting groove, and the face of cylinder projection of five lock pearls has a muscle 7, and when lock pearl inserts mounting groove, its muscle projects in keyhole from notch; At the bottom of portion in described lock housing, middle is fixed with lock pearl deck 8.The length of the Length Ratio lock pearl 6 of the muscle 7 of described lock pearl projection is short, and the length of each muscle is unequal, and between muscle and muscle, to differ from growing to most the shortest be 0.7 mm, 1.65mm, 2.55 mm, 3.5mm to length successively.

Between the muscle that above the utility model embodiment provides and muscle, to differ numerical value be generally to design optimum distance to length; those skilled in the art can extrapolate other distance scheme by reference to this easily apart from scheme, thus the protection domain of this patent should comprise inspired by this kind of scheme to calculate out other apart from scheme.

Claims

1. a novel lock, it comprises key, lock core, spring, lock pearl, lock housing, snap ring, is characterized in that round keyhole, being provided with five lock pearl mounting grooves around on lock core, the notch of described lock pearl mounting groove communicates with keyhole, article five, spring and five lock pearls are in turn inserted into respectively in lock pearl mounting groove, in the face of cylinder projection of locking pearl, have a muscle, and when lock pearl inserts mounting groove, its muscle projects in keyhole from notch; At the bottom of portion in described lock housing, middle is fixed with lock pearl deck.

2. a kind of novel lock according to claim 1, is characterized in that the muscle of described lock pearl projection, and the length of its Length Ratio lock pearl is short, and the length of each muscle is unequal, and between muscle and muscle, to differ minimum be 0.7mm to length, is 3.5mm to the maximum.
