Description

The anti-tapered end of dialling of angle spoon

The utility model is to be used to assemble tapered end and the key that high-grade locksets such as safety cabinet, cash insurance case, money silver cabinet and sedan limousine are used, and belongs to non-electronic lock class.

The China Dadong Metal Electric Appliances Fittings Factory, Xiaolan Town, Zhongshan City is in the utility model patent " a kind of anti-tapered end of dialling " of application on July 7th, 1999, and the patent No. is 99236547.3.This utility model provides a kind of anti-group performance good, and mutual opening rate is low, and key is difficult for imitated novel lockset.But structurally still there is certain weakness in this utility model patent.(1) the anti-spring of installing on the plug-in unit of dialling, its active force expands outwardly, and has so just increased the wearing and tearing between lock core and the tapered end, has reduced the durability of lockset.(2) the anti-plug-in unit of dialling is the lateral pressure of draw-in groove enters angle flange pellet shot from a slingshot when being subjected on the tapered end inwall a pin-and-hole.In other words, whenever, in any case, the rotational lock core lateral pressure all can produce at any time, the corresponding like this reliability that has reduced anti-group.

The purpose of this utility model provides the anti-tapered end of dialling of a kind of angle spoon, thereby solves two problems that exist on the said structure, improves the durability and the anti-reliability of dialling of lockset, makes product more become perfect.

The utility model improves on the basis of " a kind of anti-tapered end of dialling ", the first step is the anti-group plug-in unit in the hole of the one side lower end band several cylinders body of former cuboid and placement spring to be changed system into have notch above cuboid, the one side lower end is several cone shape pins, places the hole of spring and removes not.Second step was that the cylindrical hole with tubular angle flange pellet shot from a slingshot side makes round taper hole into, to match with anti-several conical pins of dialling on the plug-in unit; The cylinder pin is arranged at the top of angle flange pellet shot from a slingshot.Therefore, the utility model continues use angle flange pellet shot from a slingshot, the angle flange that cooperates with the angle key tooth flower is arranged on the angle flange pellet shot from a slingshot, the angle of angle flange and angle key turnover direction is greater than 0 °, the angle flange is along angle flange pellet shot from a slingshot random distribution, had angle to arrange, the key tooth flower that is complementary with the angle flange also processes the angle key.The 3rd step was to open a draw-in groove on former tapered end inwall, had a triangle or circular locating slot or hole on the corresponding orientation of former draw-in groove again.Meanwhile, have a columniform positioning bead circular hole on the corresponding direction of lock core, place energizing spring and steel ball in circular hole, steel ball can fall into triangle or the circular locating slot of digging on the tapered end inwall.

The utility model has the advantages that significantly: (one) structure more becomes rationally, simple and convenient assembly, and operation is freely, and is safe and reliable.(2) structural change has greatly reduced the frictional force between lock core and the tapered end, improves the durability of whole lockset.(3) further improve the anti-reliability of dialling of lockset, it is perfect that product more becomes.

Further set forth structure of the present utility model below with reference to the accompanying drawings.

We are as can be known with reference to the accompanying drawings: the anti-tapered end of dialling of angle spoon, form by key 1, tapered end 2 and lock core 3 etc., its first design feature be a cuboid simultaneously have spring 8 is arranged in notch 5, the notch 5, the anti-plug-in unit 10 of dialling that there is several cone shape pins 11 the one side lower end is embedded in the side of lock core 3, tubular angle flange pellet shot from a slingshot 4 is embedded in anti-and dials in the plug-in unit 10 cylinder-shaped marble hole 6 at an angle of 90, there is round taper hole 12 angle flange pellet shot from a slingshot 4 sides, there is cylinder pin 13 on the top, and the top also can be a flat-top.Its second design feature is to be connected with angle key 1 on lock core 3 in a side angle degree spoon groove 7 in cylinder-shaped marble hole, and angle key 1 matches with angle flange pellet shot from a slingshot 4.Its 3rd design feature is to have at tapered end 2 inwalls

Shape draw-in groove 9 has triangle or circular locating slot 14 on the corresponding orientation of draw-in groove 9; Have a cylindrical location notch hole 15 at lock core 1 outer wall, in location notch hole 15, place energizing spring 16 and steel ball 17.Its 4th characteristics are that the front end at lock core 3 is connected with anti-drilling steel bar 18.

The utility model has solved two problems that exist on " a kind of anti-tapered end of dialling " structure emphatically.When our practical operation, when inserting the angle key that lock core cooperated, angle flange pellet shot from a slingshot will closely cooperate because of the angle tartar with this key, all fold again up and down, and put in place, the anti-group plug-in unit contraposition of hole and conehead pin prevents that the internal-direction-force of dialling the plug-in unit upper spring is inserted in the angle flange pellet shot from a slingshot the anti-plug-in unit of dialling automatically, prevents that the tapered end draw-in groove is left in the upper surface of group plug-in unit, lockset just can rotate like this, promptly opens or opens; Otherwise, when the angle key is extracted lock core out, the relation of angle flange pellet shot from a slingshot and key angle, angle flange pellet shot from a slingshot rotates freely about thereupon, and the spring on the irregular angle flange pellet shot from a slingshot is depressed, at this moment, the round taper hole on the angle flange pellet shot from a slingshot side will be prevented dialling plug-in unit and push away conical bore because of the relation of gradient and the active force of spring, anti-upper surface of dialling plug-in unit promptly enters in the tapered end draw-in groove, realized the effect of locking, at this moment lockset just can not rotate, and promptly lockset can not be opened.In addition, key structure parts of the present utility model---the anti-plug-in unit of dialling, its motion is that the internal-direction-force by spring is pressed into naturally in the angle flange pellet shot from a slingshot conical bore and resets, and lock core could rotate.But after taking out key, the anti-plug-in unit of dialling breaks away from angle flange pellet shot from a slingshot again, and these angle flange pellets shot from a slingshot are straggly inconsistent, and any steel disc or MASTERKRY can not be opened this lockset.Therefore the anti-group performance of this lockset is fabulous, and mutual opening rate is extremely low, is a kind of antitheft anti-high-grade lockset of giving away secrets.
