Description

Buckshot handset tool tapered end

Technical field

The utility model relates to a kind of lockset, especially relates to a kind of mechanical lock head.

Background technology

The spring of known mechanical lock tapered end has two pellets shot from a slingshot in the pellet shot from a slingshot hole in lock body, during lock-out state, a pellet shot from a slingshot in lock core, a pellet shot from a slingshot between lock core and lock body, mutual opening rate height, its poor stability.200,961,386 1 kinds of mechanical spring lock heads of Chinese patent have lock gall, pellet shot from a slingshot, pellet shot from a slingshot spring in the lock body, notch is arranged on the pellet shot from a slingshot, and lock gall has slide block along the axis both sides, and there is spring on both sides between two slide blocks, with the lock body inboard of two slide block coplanes deep-slotted chip breaker are arranged.When unblanking, key inserts the lock gall key, and the pellet shot from a slingshot notch that all are unordered is adjusted to same plane, and align with the limit of two slide blocks, rotate lock gall this moment, the cambered surface of slide block is subjected to that the thorax deep-slotted chip breaker pushes in the lock body, overcome the thrust of spring, enter into the pellet shot from a slingshot notch, lock gall can rotate in lock body.After extracting key, pellet shot from a slingshot, sets back under two spring actions betwixt of two slide blocks at the pellet shot from a slingshot spring, and slide block is pushed in the deep-slotted chip breaker of lock body, and tapered end is in locking states.Because pellet shot from a slingshot is two row, a plurality of, the tartar amount is big, and difficulty of technical opening increases, and safety improves.Its less than one is that noise is big when unblanking; The 2nd, because tapered end feel when opening is not obvious, so key takes out relatively difficulty in lock body.

Summary of the invention

The utility model mainly is to solve the existing in prior technology deficiency, thereby sound is slight when developing a kind of unblanking, and the obvious key of feel plugged buckshot handset tool tapered end easily when tapered end was opened.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of buckshot handset tool tapered end, has lock body, lock core is arranged in the lock body, lock core is provided with double multiple row pellet shot from a slingshot hole, be provided with spring and pellet shot from a slingshot in the pellet shot from a slingshot hole, it is characterized in that the pellet shot from a slingshot in the described lock core is the cylinder that head is arc surface, at the cylindrical cannelure that axially has, cannelure width on described each pellet shot from a slingshot equates that axial location does not wait; The lock core both sides have the axial keyway that is communicated with the pellet shot from a slingshot hole, are stamped push pedal on the keyway, and described push pedal contacts one side and is provided with the plush copper that protrudes from blade face with pellet shot from a slingshot, and plush copper width and height match with cannelure groove width and groove depth, and the outside of push pedal is an inner concave arc surface; The two ends medial surface of push pedal is provided with and pushes away spring, described pushing away in the spring pushing hole that spring is installed in lock core; There is the needle roller that matches with push pedal described push pedal outside.Adopt needle roller to contact, when lock core rotates, transfer the cooperation of rolling in lock body, reduce noise by slip with the lock body inwall.Described lock body inboard is provided with two axial arc elongated slots, and described arc elongated slot is corresponding with the keyway of lock core both sides.

Therefore, the beneficial effects of the utility model are that safety greatly improves because pellet shot from a slingshot is two row, a plurality of, and difficulty of technical opening increases; Simultaneously, needle roller is equipped with in the push pedal outside, and needle roller and lock body inwall are rolling friction, and flexible when unblanking, sound is slight, and feel was obvious when tapered end was opened, and the key plug is convenient.

Description of drawings

Accompanying drawing 1 is a kind of section of structure of the present utility model;

Accompanying drawing 2 is I-I views of Fig. 1.

The specific embodiment

Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

Embodiment:

Mechanical lock head as shown in Figure 1 and Figure 2 has lock body 2, and lock core 6 is arranged in the lock body, and lock core 6 lock body 2 back of packing into fuses both with jump ring 1, can only produce radially rotation and can not move axially.Lock core is provided with double multiple row pellet shot from a slingshot hole 3, shown in the figure 7 row, be provided with spring 8 and pellet shot from a slingshot 9 in the pellet shot from a slingshot hole 3, pellet shot from a slingshot is the cylinder that head is arc surface, at the cylindrical cannelure that axially has, cannelure width on each pellet shot from a slingshot equates, axial location does not wait, the lock core both sides have the axial keyway that is communicated with the pellet shot from a slingshot hole, be stamped push pedal 5 on the keyway, push pedal contacts one side and is provided with the plush copper that protrudes from blade face with pellet shot from a slingshot 9, plush copper width and height match with cannelure groove width and groove depth, and the outside of push pedal is an inner concave arc surface; The two ends medial surface of push pedal is provided with and pushes away spring 7, pushes away in the spring pushing hole that spring is installed in lock core 6; There is the needle roller 4 that matches with push pedal push pedal 5 outsides, and needle roller rolls with the lock body inwall and contacts.Adopt needle roller contact with the lock body inwall, by prior art with to be slidingly matched be the cooperation of rolling, unlatching is flexible when lock core rotate in lock body, and noise is extremely low.Be provided with 2 axial arc elongated slots in the lock body inboard, described arc elongated slot that the position is set is corresponding with lock core both sides axial keyway.When tapered end is in locking states, because the annular groove of a plurality of pellets shot from a slingshot is a disordered state, can not form straight line, the plush copper in the push pedal 5 can't enter in the annular groove of pellet shot from a slingshot.At this moment, the elastic force that pushes away spring 7 acts on push pedal 5, and push pedal 5 acts on needle roller 4 again, and needle roller 4 tightly is stuck in the arc elongated slot of lock body inwall.When using original key to unblank, a plurality of ring groove shapes on the pellet shot from a slingshot are in alignment, and during rotary locking cylinder, needle roller 4 rolling actions are in push pedal 5, and push pedal overcomes and pushes away spring 7 elastic force and enter the pellet shot from a slingshot annular groove, and lock core 6 is rotated.During rotation, roll,, sound hardly so rotate easily owing to needle roller 4 contacts with lock body 2 inwalls.When key is not former timing, the annular groove on a plurality of pellets shot from a slingshot 3 can not form a straight line, during rotation, can't make push pedal 5 enter the annular groove of pellet shot from a slingshot, and lock core can not be rotated.

Therefore the utility model has tangible feel owing to the elastic force that pushes away spring is suitable when tapered end is opened, Key takes out in lock body.
