Description

A kind of with locking tongue clutch-plate, the tunable center distance

[technical field]

The utility model is parts of locking, and is particularly a kind of with locking tongue clutch-plate, the tunable center distance, belongs to five metals lockset manufacturing industry.

[background technology]

Have locking to sell on the domestic market, the customer is also using.But running into installing hole on the door leaf sometimes apart from the situation that the center to center distance on door limit does not wait on installing and using, is 60 millimeters sometimes, is 70 millimeters sometimes, therefore must manufacture and design the dead bolt assembly of two kinds of sizes.The dead bolt assembly that has producer to have at present can to regulate center to center distance, but structure is comparatively complicated, and inconvenient with manual adjustments.It is a kind of with locking tongue clutch-plate, the tunable center distance that the purpose of this utility model provides, and carried out new improvement, the purpose of this utility model that Here it is in tongue tube and being connected of tailstock.

[utility model content]

The purpose of this utility model provides a kind of with locking tongue clutch-plate, the tunable center distance, it utilizes and assemble adjusting rod in the tailstock of lock tongue body, assembling clutch-plate and hyoplastron in adjusting rod, and under the cooperation of clutch-plate spring and roll adjustment pin, adjusting rod can be done forward and backward translation, thereby regulates the mounting center distance of locking; The firmness that the structure increase by the tailstock wing and slot is connected on tailstock and the tongue tube simultaneously.Technical problem of the present utility model is to solve like this: the rectangle slotted eye of opening is arranged vertically in cylindrical tongue rear end, and tongue pin-and-hole of Drilling radially in these slotted eye both sides axially has a spring eye at the upper end edge of rectangle slotted eye; The hyoplastron of strip and clutch-plate are connected in the slotted eye by a tongue pin at the tongue pin-and-hole, and tongue is connected in the spring eye, the end of tongue is connected the front end of clutch-plate; Vertically be connected with the cylindrical shape resilient key on the clutch-plate rear end face, the mounting hole of the hyoplastron rear end that fits together with clutch-plate also is connected on the cylindrical shape resilient key; Have the roll adjustment bar of long trough to be linked on hyoplastron and the clutch-plate, the cylindrical shape resilient key of hyoplastron and clutch-plate rear end also is connected roll adjustment bar both sides

In the shape groove; The roll adjustment bar is connected dialling in the peach folder of flute profile, dials the peach folder and is connected again in the tailstock of flute profile; The roll adjustment pin of circular bar shape passes the tailstock both sides

The shape groove, dial peach folder front end both sides mounting hole and be connected hyoplastron and the cylindrical shape resilient key of clutch-plate rear end in.This is that of the present utility model first created main points.Fin in tailstock front end both sides is connected in the slot of tongue tube rear end, makes both in conjunction with firm.This is second of the present utility model and creates main points.The utility model is assembling like this: liner plate is riveted on the end plates of tongue tube, and the tongue cover of opening is connected on the cylindrical shell of tongue tube; Hard tongue core is connected in the centre bore vertically of tongue rear end; The crank of band " ten " word slotted eye is connected in the through hole of dialling peach folder both sides, bottom, and crank spring one end of strip is connected to be dialled on the peach folder front end bottom surface, and an end is articulated in the jack of dialling peach folder rear end face; At the roll adjustment pin two ends socket post head of a nail of circular bar shape, thumb and forefinger can be seized on both sides by the arms on the post head of a nail, can shouting pain finger, adjusting (moving forward and backward) roll adjustment pin easily.The situation that the utility model is assemblied in the locking is such: pass from locking tail-hood plate, the utility model are the screw of locking tongue body, locking protecgulum by long spiro nail, be tightened at last in the screw of locking tapered end, make it to connect into as a whole.In the utility model, roll adjustment bar both sides The shape groove, The center to center distance of the straight shape groove of groove both sides is 10 millimeters.When the roll adjustment pin is vertically connected on In the time of in the straight shape groove on the shape groove left side, the distance of the center to center distance liner plate of " ten " word slotted eye of crank is 60 millimeters, then can be installed in the door leaf opening on the door leaf of 60 millimeters of Men Bianwei.When the roll adjustment bar is existed Up mention in the shape groove and move to the right straight shape groove in the time, at this moment crank " ten " word slotted eye has been drawn back far 10 millimeters, promptly the distance of the center to center distance liner plate of " ten " word slotted eye is 70 millimeters, at this moment, then the utility model can be installed in center to center distance and be on 70 millimeters the door leaf.Here seize on both sides by the arms on the post head of a nail at the two ends of roll adjustment bar with thumb and forefinger, slightly up mention, left and right then move very convenient, do not need much strength yet, be that roll adjustment bar and group peach are pressed from both sides together with crank in moving process, forward and backward moving in tailstock, thereby the change distance.From the above, the utility model has the advantages that significantly: (one) is novel in design, rational in infrastructure; (2) structure is firm, and assembling easily, and is easy to use; (3), remove and use in locking, also can be assemblied on other lock body, of many uses.
