Description

Interior crescent lock of pressing the locking of outer bullet straight pin

Technical field:

The utility model is a kind of tapered end commonly used, particularly a kind of interior outer crescent lock that plays the straight pin locking of pressing, genus five metals lockset manufacturing technology.

Background technology:

Single crescent lock is a kind of tapered end of having many uses, and wherein key simultaneously is a circular arc, the single tartar perpendicular to the key plane is arranged, so the single crescent lock of called after in the middle of another facing cut hole.It uses wide, and cost of production is low, and theftproof performance is good, and making convenient is its advantage.This kind tapered end still has weakness.It has only five kinds of hoodles in lock core, i.e. 1.2.3.4.5 hoodle, and length is identical; The depth of threat of key is respectively 0.2,0.7,1.3,1.8,2.3 millimeter.The differential of hoodle is 0.5 millimeter, has only ought differentially reach more than 0.7 millimeter, and the mutual opening rate of its tapered end is just guaranteed.Its weakness be lock core locking be cubic lock pin, lock core has when opening and has some setbacks, and add lead powder and could rotate shortcoming smoothly.Therefore, single crescent moon tapered end has improved necessity.The present utility model people fights in the lockmaking industry for a long time, has accumulated abundant lockmaking experience, audaciously traditional single crescent lock is improved, and the utility model arises at the historic moment in this situation.

The utility model content:

The purpose of this utility model provides a kind of interior outer crescent lock that plays the straight pin locking of pressing, it is an assembling triangle cone removable pin in lock core, and at triangle cone removable pin rear end component location guide pin, after key inserts keyhole, the tartar degree of depth of key is consistent with the drop of the pellet shot from a slingshot of combination, and the triangular pyramidal groove on the pellet shot from a slingshot body is unlocking condition in line; After transfering to key, pellet shot from a slingshot is down fallen by spring pressure, and being depressed on the interface of lock core and tapered end in triangle cone removable pin and the straight pin, straight pin locks lock body.The utility model modern design, rational in infrastructure, go slick, accurate, and theftproof performance improves.The technical scheme of the utility model technical solution problem is such, and for improving theftproof of the present utility model, triangle cone removable pin and two structures of straight pin are introduced in inventor's decision in lock core and tapered end, improved its theftproof performance greatly.The utility model comprises: tapered end, lock core, keyhole, crescent key, cylindrical hoodle hole, axial waist through hole, semicolumn groove, pyrometric cone body hoodle, hoodle spring, sword iron and jump ring.Its first design feature is an assembling triangle cone removable pin in the axial waist through hole of lock core, at triangle cone removable pin rear end component location guide pin; It is that triangle cone, two ends are circular arc body, in the rear end of " Jiong " shape body rectangular recess are arranged that described triangle cone removable pin has " Jiong " shape body, front end; Its second design feature is to dig at the lock core end face crescent keyhole is arranged, digging several cylinders shape hoodle hole with crescent keyhole vertical direction, digging an axial waist through hole with cylindrical hoodle hole vertical direction, with the corresponding tapered end inwall of axial waist through hole on cutting semicolumn groove; At cylindrical hoodle hole assembling pyrometric cone body hoodle, described pyrometric cone body hoodle has the triangular pyramidal groove on its pearl body, at triangular pyramidal hoodle rear end assembling hoodle spring; Assembling triangle cone removable pin in waist through hole is at triangle cone removable pin rear end component location guide pin; Lock core is assemblied in the tapered end, connects sword iron and jump ring in the rear end of lock core; Its 3rd design feature is that tapered end and lock core can be assemblied in the multiple lockset; Keyhole at lock core patches the crescent key.In sum, advantage of the present utility model is as follows:＜one〉novel in design, rational in infrastructure, introduction triangle cone removable pin and straight pin greatly improve its theftproof performance in single crescent lock;＜two〉lock core of straight pin locking rotate smooth and easy, open flexibly, significantly reduce lock core and open frictional force when rotating, the application life of having improved lockset;＜three〉manufacturing is easy for installation, and cost of production is low, has the market competitiveness, is subjected to customer's welcome.

Description of drawings:

The explanation and the specific embodiment are further understood structure of the present utility model with reference to the accompanying drawings below.

Accompanying drawing 1 is a sectional plan view of the present utility model;

Accompanying drawing 2 is looked or stereogram for the master of each parts of the present utility model;

Accompanying drawing 3 is each parts assemble sequence stereogram of the present utility model.

In the accompanying drawing: 1, tapered end, 2, lock core, 3, keyhole, 4, crescent key, 5, cylindrical hoodle hole, 6, axial waist through hole, 7, semicolumn groove, 8, pyrometric cone body hoodle, 8-1, triangular pyramidal groove, 9, hoodle spring, 10, sword iron, 11, jump ring, 12, triangle cone removable pin, 12-1, " Jiong " shape body, 12-2, triangle cone, 12-3, circular arc body, 12-4, rectangular recess, 13, straight pin.

The specific embodiment:

Make each parts of the utility model with reference to the accompanying drawings, and assemble by accompanying drawing 3 orders.Inventive point of the present utility model is two: the one, and triangle cone removable pin 12, it is " Jiong " shape body 12-1, and its front end is triangle cone 12-2, and two ends are circular arc body 12-3, and there is rectangular recess 12-4 the rear end; It is to be assemblied in the axial waist through hole 6 of lock core 2 sides.At the rear end of triangle cone removable pin 12 component location guide pin 13.Insert hoodle spring 9 in order, reinstall pyrometric cone body hoodle 8 for 5 li in cylindrical hoodle hole, fill in lock core 1 in the tapered end hole of tapered end 1 together with above-mentioned parts then; The sword iron 10 of flatly packing in lock core 2 rear ends is then fixed sword iron 10 with jump ring 11 again, and the utility model has just assembled successfully substantially, as shown in Figure 1.Below our function situation of the present utility model.When crescent key 4 inserts the keyhole 3 of lock core 2, at this moment the pyrometric cone body hoodle 8 that originally fell in cylindrical hoodle hole 5 li in lock core 2 is come by crescent key 4 jack-up, under the tartar effect of crescent key 4, the triangle cone tank 8-1 of all pyrometric cone body hoodles 8 is in alignment, at this moment triangle cone removable pin 12 is under the effect of internal pressure, the triangle cone 12-2 of its front end enters in the triangle cone tank 8-1 of pyrometric cone body hoodle 8, straight pin 13 in triangle cone removable pin 12 rear ends also then enters in the lock core 2, straight pin 13 enters in the lock core 2 fully under the effect of crescent key 4 turn power, lock core 2 smooth and easy rotations, lock body promptly is unlocked.When from lock core 2, transfering to crescent key 4, under the elastic force effect of marble spring 9, all pyrometric cone body hoodles 8 all drop in the lock core 2, triangle cone removable pin 12 is promoted outside lock core 2, make straight pin 13 enter into 7 li of the semicolumn grooves of tapered end 1, on the interface of tapered end 1 and lock core 2 handing-over, lock core 2 can not rotate straight pin 13 with regard to horizontal stalk like this, and lock body is locked.
