Abstract

The present invention is a kind of cylinder of spring lock without key hole, main feature is that every row's pellet shot from a slingshot is parallel with lock core shaft, axially-aligned, going up most pellet shot from a slingshot descends pellet shot from a slingshot to be trapezoidal shape most, to go up pellet shot from a slingshot most when key presses and the lock core shaft outer face, pellet shot from a slingshot contact surface and lock core shaft's inner face leveling up and down, screw key can be unblanked, compare with existing cylinder of spring lock, owing to cancelled keyhole, pellet shot from a slingshot hole axially-aligned, have and be convenient to handle, with copper take place of steel, advantages such as sealing, theftproof raising can be used to prepare the cylinder lock of various different purposes.

Description

Cylinder of spring lock without key hole

The invention belongs to technical field of buildings, is a kind of cylinder of spring lock without key hole.

Existing cylinder lock, keyhole are the copper material kerve, and pellet shot from a slingshot is vertical with lock core shaft in lock core to be transversely arranged, exist keyhole, pellet shot from a slingshot hole difficulty of processing is big, inconvenience handle and use in felt shortcoming such as easily blocked, the destruction of keyhole.

The objective of the invention is to design the cylinder of spring lock that a kind of pellet shot from a slingshot hole easily processed, do not have keyhole.

The technical measures that the present invention takes are with pellet shot from a slingshot transversely arranged axially-aligned that changes in lock core, adjacent two pellet shot from a slingshot plane contact, go up most and descend most pellet shot from a slingshot to be trapezoidal, the thin end of going up most pellet shot from a slingshot is towards (exposing) lock core shaft outer face, descend most pellet shot from a slingshot carefully to hold at the bottom of the pellet shot from a slingshot hole, the pellet shot from a slingshot contact surface has been cancelled keyhole by on the interior transverse plane that changes on the round bolt face of lock core shaft in lock core shaft about during unlatching.

Reach the specific structural features that example further specifies cylinder of spring lock without key hole of the present invention in conjunction with the accompanying drawings.

Fig. 1 represents that cylinder of spring lock without key hole master of the present invention looks schematic diagram; And as Figure of abstract.

Fig. 2 represents cylinder of spring lock without key hole schematic side view of the present invention.

Referring to Fig. 1, Fig. 2, cylinder of spring lock without key hole of the present invention comprises lock core body 1, descends marble pressuring spring 2 most, descends pellet shot from a slingshot 3 most, goes up pellet shot from a slingshot 4 most, lock core shaft 5, key pin 6.Every row's pellet shot from a slingshot have at least go up most, the most following two pellets shot from a slingshot, parallel with lock core shaft 5, axially-aligned, adjacent two pellet shot from a slingshot plane contact, go up most pellet shot from a slingshot 4 and descend pellet shot from a slingshot 3 to be trapezoidal shape most, go up pellet shot from a slingshot 4 most and carefully hold by trapezoidal pellet shot from a slingshot hole, descend pellet shot from a slingshot 3 carefully to hold at the bottom of the pellet shot from a slingshot hole most towards the outer face 7 of exposing lock core shaft 5, and be inserted in compression spring 2, in lock core shaft 5, be provided with key pin 6.

Key is a cylinder, and end and go up the pellet shot from a slingshot correspondence most and establish the pellet shot from a slingshot jack is with alignment pin 6 corresponding setting position pin-and-hole and rotary stopper grooves.When the corresponding alignment pin of key, go up pellet shot from a slingshot most, and when pressure and lock core shaft outer face 7, the contact surface of pellet shot from a slingshot and lock core shaft's inner face 8 leveling screw keys can be unblanked up and down, descend the thin end of pellet shot from a slingshot to withstand at the bottom of the pellet shot from a slingshot hole most, go up most the pellet shot from a slingshot hole of pellet shot from a slingshot and still locate closed state, in any foreign matters is gone into; Lock core has been cancelled keyhole, without kerve processing, then is convenient to adopt steel carburizing part and antirust processing; Pellet shot from a slingshot hole axially parallel is arranged than horizontal vertical arrangement and is easy to processing, percentage of A-class goods height; This lock core marble row number, marble amount, number number can determine arbitrarily that double sign is few, the secrecy height.In a word, compare, have handling ease, be convenient to handle, with advantages such as copper take place of steel, sealing confidentiality, anti-destructive, theftproof significantly improve with existing cylinder of spring lock.

This cylinder of spring lock of the present invention can be used to prepare the cylinder lock of various different purposes.

Claims

1, a kind of cylinder of spring lock without key hole, have lock core body, have at least and go up to descend most pellet shot from a slingshot, lock core shaft most, it is characterized in that every row's pellet shot from a slingshot is parallel with lock core shaft, axially-aligned, adjacent two pellet shot from a slingshot plane contact go up pellet shot from a slingshot most and descend most pellet shot from a slingshot to be trapezoidal shape, go up pellet shot from a slingshot most and carefully hold by trapezoidal pellet shot from a slingshot hole towards the outer face of exposing lock core shaft, descend most pellet shot from a slingshot carefully to hold at the bottom of the pellet shot from a slingshot hole, in lock core shaft, be provided with key pin.
