Description

Two section trumpet door lock

The utility model relates to lockset, is that a kind of device is on wing and have a loudspeaker door lock of knob.

General loudspeaker door lock commonly used at present all mainly is made of forward and backward head of the trumpet (being tubaeform rotation handgrip) and spring bolt mechanism, after spring bolt mechanism is set in the doorframe side, positioning housing partial fixing with preceding head of the trumpet, include a square drive link in the rotating part of preceding head of the trumpet, it is connected with the back head of the trumpet after passing the rotating block that has square opening of spring bolt mechanism, because of the rotating block of spring bolt mechanism connects mutually with dead bolt, then rotate head of the trumpet and can make dead bolt flexible and open and close door-plate.Existing this door lock, in use exist the difficulty of making and installing, mainly be, the door-plate of general at present use loudspeaker door lock roughly has boarded door and metal door two classes, and the internal construction of boarded door and metal door is not quite similar, then the door lock assembly size is variant, difficulty when causing the dress lock, as, if device is on wooden door board the time, about 6 centimetres away from door edge be at its door lock center is if device is about 8.5 centimetres from the door edge in its door lock center on aluminium door the time, then door lock, must manage to transform door inside casing partial structurtes to same, but this not a duck soup; Perhaps change different door locks, but this needs again the lockmaking dealer to produce the door lock of different size according to the difference of door-plate, disposes the different dead bolt of length, this has increased complexity for again the lockmaking dealer, and also the person has brought trouble to purchasing the lock.

The purpose of this utility model is to provide a kind of two-part horn lock, installs and uses so that be suitable for multiple door-plate.

For achieving the above object, the utility model adopts following technical scheme: the same with prior art, the utility model is mainly by preceding head of the trumpet, and back head of the trumpet and spring bolt mechanism constitute, and spring bolt mechanism comprises anterior kayser body, rear portion fixed body and places wherein dead bolt.For the utility model door lock can be installed on the multiple door-plate, the spy respectively is provided with twice fastening ditch on the upper/lower terminal face of the fixed body of spring bolt mechanism, and the through hole that two tangent circle arcs constitute is set on the forward and backward sidewall of fastening postsulcal part on this fixed body, dispose with the right-hand formula of a first from left in the front and back ends of this pair arc through hole and be square hole with in order to place the rotating block of square drive link.So the spring bolt mechanism of structure then becomes the two-part structure, when this door lock assembly on boarded door the time, can utilize the first road fastening ditch, the edge of the positioning housing of head of the trumpet part is fastened in this first road fastening ditch before making, with the positioning and fixing spring bolt mechanism, simultaneously, the square drive link of the rotating part of preceding head of the trumpet is set in the rotating block square hole that is arranged in the right; When this door lock assembly on metal panels the time, can utilize the second road fastening ditch and be positioned at the rotating block on the left side.

See by last structure, the utility model has the advantages that, because of spring bolt mechanism has two road fastening ditches and left and right two rotating blocks, then can select different spring bolt mechanism installation sites when mounted according to different door-plates, therefore, behind employing the utility model, same lock can be installed on the dissimilar door-plates, highly versatile, this is to making, buy and the door lock person being installed all having brought convenience.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described specifically.

Description of drawings:

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is the schematic perspective view of the spring bolt mechanism of the utility model.

Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are locking, the unlocking condition figure of spring bolt mechanism when two kinds of positions of the utility model.

See also Fig. 1.See that by figure present embodiment mainly is made of preceding head of the trumpet 1, back head of the trumpet 2 and spring bolt mechanism 3.Wherein, the preceding head of the trumpet 1 inboard middle square drive link 10 that is provided with, this periphery, inside edge is provided with upper and lower each arc- like sheet 11,12 of one, and the adjacent both sides of this two arc- like sheet 11,12 are made the breach 13 of convex shape, for being embedded spring bolt mechanism 3, be protruding with standing screw 14 in the centre of two arc- like sheets 11,12 again, with spiral shell is solid mutually so that preceding head of the trumpet 1 is with back head of the trumpet 2; The back head of the trumpet 2 inboard middle square openings that are provided with, square drive link 10 for preceding head of the trumpet 1 places, simultaneously, be provided with locating piece 21 in its square opening outside and with corresponding section, screw rod 14 position on two arc- like sheets 11,12 of preceding head of the trumpet 1, for the spiral shell fixed bit.See by figure, the front portion of spring bolt mechanism 3 is a kayser body 31, the rear portion is the fixed body 32 that is the casket shape, on this fixed body 32, the lower surface is provided with twice fastening ditch 320, and be provided with by what two tangent circle arcs constituted in the front and back sidewall of the fixed body 32 at fastening ditch 320 rear portions and run through through hole 33, before this through hole 33, rear end face is (preceding, on the rear wall) in the right-hand formula device of a first from left rotating block 34 that is square hole is arranged, promptly be equiped with rotating block 34 in half through hole of the left side on the front side wall of fixed body 32, also be equiped with a rotating block 34 in the right side half through hole on rear wall, and on the rotating block 34, the lower end all is provided with lug 340, and this lug 340 is the overlap joint state with the pin body 301 of dead bolt 30.

See by Fig. 2, door-plate according to different structure, the square drive link 10 of head of the trumpet 1 places the leading portion of fixed body 32 of spring bolt mechanism 3 or the square hole (being the square hole of back segment rotating block 34 shown in the figure) of back segment rotating block 34 before the order, correspondingly the convex shape breach 13 of preceding head of the trumpet 1 is embedded in the fastening ditch 320 on the fixed body 32 of spring bolt mechanism 3,32 of fixed bodies are positioned at the breach 13 closing ins place outside.After so installing, when head of the trumpet was rotated, the square drive link 10 in it promptly drove rotating block 34 and rotates current (or back), and the lug 340 on this rotating block 34 promptly spurs the pin body 301 of dead bolt 30, makes dead bolt 30 produce flexible state, reaches the purpose that opens and closes door-plate.

Please read Fig. 3, Fig. 4, Fig. 5 and Fig. 6 again.If the utility model door lock assembly is on aluminium door the time, because of the distance of door lock center isolated edge bigger, then adopt Fig. 3, mounting means shown in Figure 4, promptly square drive link 10 is set in the square hole of back segment rotating block 34, correspondingly, in the second road fastening ditch 32 of convex shape breach 13 holdings that two arc- like sheets 11,12 are constituted on the preceding head of the trumpet 1 on spring bolt mechanism 3 fixed bodies 32; When the utility model door lock assembly is on timber, then adopt Fig. 5, mounting means shown in Figure 6, promptly square drive link 10 is set in the square hole of leading portion rotating block 34, correspondingly, in the first road fastening ditch 320 of convex shape breach 13 holdings on spring bolt mechanism 3 fixed bodies 32 that two arc- like sheets 11,12 constitute on the preceding head of the trumpet 1.
