Abstract

The utility model discloses a billiard tongue-rotating lock with an opening-closing positioning, which comprises a lock shell, a lock core that is embedded inside the cavity of the lock shell and a key that is matched with the lock core for application, wherein, a plurality of lock-core pin holes are arranged at the tail section of the lock core along with the circumferential radian, and a plurality of lock-shell pin holes are arranged at the tail section of the corresponding lock shell, which are provided with pins in cooperation; the measures adopted by the utility model comprises that at least six groups of lock-core billiard holes, which are distributed in the longitudinal direction at intervals, are arranged at the middle section of the lock core, and are communicated with the corresponding groups of lock-shell billiard holes that are arranged at the middle section of the corresponding lock shell, and both of the lock-core billiard holes and the lock-shell billiard holes are provided with a plurality of billiard components in cooperation; each group of the billiard components is composed of pressure springs that compress the billiards and sharp-head billiards that are compressed against by flat billiards in turn; the head end surface of the lock shell is provided with two lock-shell steel-ball positioning grooves, and the head end surface of the lock core is also provided with two lock-core steel-ball positioning grooves that correspond to the opening position and the closing position of the lock; a steel-ball positioning pressure spring and a positioning steel ball are arranged inside the lock-shell steel-ball positioning grooves. The utility model has better privacy and better hand touch feeling when unlocking and locking the lockset.

Description

Band opens and closes the pellet shot from a slingshot turning-bolt lock of location

Technical field

The utility model relates to the technical field of steel office furniture cylinder lock, is specifically related to the pellet shot from a slingshot turning-bolt lock that opens and closes the location.

Background technology

Along with The development in society and economy, people are increasing to the demand of steel office furniture, but security performance as steel office furniture lock, especially in a large number use locating of lockset as safe deposit box, changing-box, cabinet etc., on the keying feel of outward appearance and lock, in the past few years, never carried out desirable improvement in this industry the inside of making steel office furniture lock.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of security performance more excellent, and feel was better with the pellet shot from a slingshot turning-bolt lock that opens and closes the location when lockset opened and closed.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: band opens and closes the pellet shot from a slingshot turning-bolt lock of location, comprise lock housing, be inlaid in lock core in the lock housing cavity and the key that matches with lock core, the lock core rear is shaped on the lock core pin-and-hole of offering along the circumference radian, be shaped on the lock housing pin-and-hole with corresponding lock housing rear and connect, and cooperation is penetrated with pin; The measure of taking comprises: the lock core stage casing is shaped at least six group lock core marble holes longitudinally spaced apart, the lock housing pellet shot from a slingshot hole that is shaped on the respective sets number with corresponding lock housing stage casing connects, and all cooperation is penetrated with the pellet shot from a slingshot assembly, and every group of pellet shot from a slingshot assembly is all in proper order by pressing pellet shot from a slingshot compression spring, flat pellet shot from a slingshot to compress the tip pellet shot from a slingshot and constitute;

The lock housing end surface offers, corresponding two lock core steel ball locating slots that also offer corresponding respectively lock opening and closing position at the lock core end surface; Be equipped with steel ball positioning pressure spring and locking ball in the lock housing steel ball locating slot.

For optimizing technique scheme, the measure of being taked also comprises:

Above-mentioned pressure pellet shot from a slingshot compression spring other end butt is installed in the strip of paper used for sealing on the lock housing, and the tip pellet shot from a slingshot other end cooperates the corresponding spoon of key tooth.

Above-mentioned lock housing end surface is provided with protective cap.

Compared with prior art, the utility model is not changing original lockset installation dimension on furniture, be under the constant prerequisite of lockset appearance and size, through ingenious design, be shaped at least six group lock core marble holes longitudinally spaced apart in the lock core stage casing, the lock housing pellet shot from a slingshot hole that is shaped on the respective sets number with corresponding lock housing stage casing connects, and all cooperation is penetrated with the pellet shot from a slingshot assembly, and every group of pellet shot from a slingshot assembly is all in proper order by pressing pellet shot from a slingshot compression spring, flat pellet shot from a slingshot to compress the tip pellet shot from a slingshot and constitute; Make the security performance of lock improve more than four times, simultaneously, feel when using specific lock housing steel ball locating slot and lock core steel ball locating slot structure to the lockset opening and closing has also been done improvement, make lockset that a kind of sensation to the position be arranged when opening and closing, this is former also to be unprecedented.
