Abstract

The utility model provides an improved adjustable bolt structure which is characterized in that the adjustable bolt is provided with a four-link assembly parallel with a crank which swings in parallel for opening and closing the bolt ( The swing of the four-link assembly parallel with a crank is like a rain brush for a car.). The four-link assembly parallel with a crank is provided with a jack of a turning handle pole with at least two holes. The appropriate position can be chosen and arranged according to the size of the door plate, which realizes convenient arrangement, firm and practical structure, and beautiful appearance. The function of locking the bolt can be achieved, and the theft of opening the lock and entering the room can be avoided. Therefore, the improved adjustable bolt structure is of great security.

Description

A kind of improved adjustable bolt structure

Technical field

The utility model relates to a kind of locking part, relates in particular to a kind of improved adjustable bolt structure

Background technology

A kind of bolt A of prior art, as shown in Figure 1, it is to utilize a door lock B to be fastened in bolt to set firmly (as shown in Figure 2) in the hole, can reach the function of closing door lock and unlatching by key C.Yet,, install inconvenient because of the door lock volume is big, and it is big to occupy the door-plate area, cause assembling to be provided with after, may limited door-plate area, cause insecure phenomenon,, door lock is opened easily when the burglar damages because of the bolt strength deficiency when pushing hard outdoors, and enter in the room, then, cause within doors the property thief that is stolen to steal, suffer heavy losses, and this is personnel within doors, subject to burglar or ruffian and injure its life security, and therefore above-mentioned existing Latch lock is real in lacking practicality and safety.

Summary of the invention

In view of this, the purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, a kind of improved adjustable bolt structure is provided, this adjustable bolt structure is by being provided with parallel crank four connection rod set, make it do parallel oscillating motion and come open and close bolt (just as the windshield wiper swing), its parallel crank four connection rod set have two holes at least and stir can be according to the different choice of the door-plate size suitable position of handlebar stem jack and do best choosing and establish, reach easy for installation, firm, practical and attractive in appearance, and can reach the function of locking bolt and prevent that the burglar from unblanking to enter.

The purpose of this utility model realizes by following technical proposals, improved adjustable bolt structure of the present utility model mainly by: combination of components such as adjustable bolt, door lock, key and screw are formed; Wherein this adjustable bolt is provided with the latch base body, this latch base body rear is installed a spring, this latch base body and is installed and be provided with open-work and parallel crank four connection rod set are installed and block with spring, these parallel crank four connection rod set can be done parallel motion, the bolt trip inserts the front end open-work that the latch base body is installed, the bolt trip is installed on groove and can lives the swing connecting bar frame that parallel crank four connection rod set are connected with, and can form and do the motion of a parallel crank four connection rod set; One latch base lid contains and sets firmly a slotted eye and be installed on the latch base body and set firmly the hole, and this slotted eye position sets firmly the backstay frame with the bolt trip just, and steady pin inserts latch base and covers and set firmly the hole and penetrate the latch base body again and set firmly the hole and form fixing.Form adjustable bolt like this, with screw adjustable bolt is fixed on the door-plate, adjustable bolt is put into the suitable point of door-plate, door lock is entangled door lock lid pass adjustable bolt and cooperates with other end door lock lid, and screw passed the door lock lid and door lock locks and key plugged finish assembling.

This adjustable bolt of described adjustable bolt forms mechanism: it contains parallel crank four connection rod set (just as the windshield wiper swing) and these parallel crank four connection rod set and contains to establish and stir handlebar stem jack at least two holes, with door lock be connected with put stir handlebar stem insert parallel crank four connection rod set contain establish stir the handlebar stem jack, because of parallel crank four connection rod set starts and then drive bolt and stretch out or withdraw and reach bolt open and close action, and can be according to the different choice of the door-plate size suitable handlebar stem jack position of stirring of this adjustable bolt is made the best and is selected and establish when stirring handlebar stem.

The specific embodiment

The improved adjustable bolt structure of the utility model cooperates icon, figure number and embodiment to be described in detail as follows:

Shown in Fig. 3,4,5 and 6, the improved adjustable bolt structure of the utility model by: combination of components such as an adjustable bolt 01, door lock 21, key 22 and screw are formed; Wherein this adjustable bolt 01 is established a latch base body 11, latch base body 11 rears are installed a spring 13, this latch base body 11 and are installed on open-work 17A and parallel crank four connection rod set 14 are installed and block tool with spring 13 and stir spring function, these parallel crank four connection rod set 14 can be done parallel motion, the continuous front end open-work 17B that bolt trip 15 insertion latch base bodies 11 are installed, bolt trip 15 is installed on groove 28 and can lives swing connecting bar 19 frames that parallel crank four connection rod set 14 are connected with, and can form and do the motion of a parallel crank four connection rod set; One latch base lid 16 contains and sets firmly a slotted eye 18 and be installed on latch base body 11 and set firmly hole 17B, these slotted eye 18 positions just set firmly backstay 26 frames firmly with bolt trip 15, steady pin 27 being inserted latch bases lid 16 sets firmly hole 17A and penetrates latch base body 11 again and set firmly hole 17C and form fixing again, form adjustable bolt 01, getting screw 10 is fixed in adjustable bolt 01 on the door-plate, adjustable bolt 01 is put into door-plate 29 suitable points, again door lock 21 is entangled door lock lid 23 and pass adjustable bolt 01 and cooperates with other end door lock lid 23 and continuously screw 10 is passed door lock lid 23 and door lock 21 locks and key 22 plugged finish assembling, as Fig. 3.

For making the utility model show its progressive and practicality more, it is as follows that elder generation and prior art constructions are done a comparative analysis:

The shortcoming of prior art:

1, door lock subjects to the burglar and destroys unlatching.
