Description

A kind of light tricycle door lock

Technical field the utility model relates to a kind of lockset, relates in particular to a kind of light tricycle door lock.

The present domestic tricycle market capacity of background technology is bigger, presents the prosperity scene that both production and marketing thrive.If present domestic owner of the tricycle is light-duty, vehicle body all mainly adopts glass fibre reinforced plastic structure, its rigidity far can not be compared with automobile, so all lack the door lock that is exclusively used in the glass fiber reinforced plastic tricycle till now, each tricycle manufacturer mostly adopts family room's Inner door lock (as: ox head board pin tumbler lock); This kind door lock had been both dangerous, also inconvenient, more not attractive in appearance.It is 01274700 that a kind of patent No. is arranged, name is called the patented technology door lock of " light tricycle door lock ", and it is interlock assembly of increase realizes pinning car door in car on the basis of the conventional lock that adopts parts such as tapered end, shift fork, lock passs, dead bolt a function.There is following deficiency in this kind lockset for the light tricycle of glass fibre reinforced plastic structure: 1. the lockset component are still many, and it is numerous and diverse that structure still shows; 2. fault rate is higher; 3. interlock assembly does not have necessity of existence, can save fully.

Summary of the invention the utility model provides a kind of component the least possible, simple in structure, cheap tricycle door lock in order to overcome above deficiency of the prior art.

The technical solution of the utility model is: a kind of light tricycle door lock, it comprises substrate, the interior group of hook, dials hook, interior catch pull bar, outer catch pull bar outward, and wherein, described substrate is made of bottom surface and side, there is an opening at the middle part of bottom surface, and two perforates are arranged on the side; Moving plate is actively connected on a side of the opening of bottom surface respectively with rotating shaft with rotating shaft, check plate; On the moving plate spring fixed column, dead bolt post groove, back stop slot, retaining flange are arranged, spring fixed block, locking tooth, spacing block set are arranged on the check plate, the retaining flange under opening with the side on a perforate collide, spacing block set stretches in another perforate on the side; Between spring fixed column and spring fixed block, be connected with spring; Dial hook in described and be actively connected on the side with rotating shaft with the outer hook of dialling, the front end of inside and outside group of hook contacts with spacing block set and can drive it and rotates;

Described perforate is rectangle or square;

Described rotating shaft is a rivet.

Tricycle door lock of the present utility model is because amount of parts is few, so fault rate is very low; Its function is similar, safe and reliable with automobile door lock fully; It is simple in structure, cheap.

The utility model is described in further detail below in conjunction with accompanying drawing for description of drawings:

Fig. 1 is that the utility model lockset is in the opening sectional view.

Fig. 2 is that the utility model lockset is in locking state schematic diagram (omission spring).

Fig. 3 be the utility model lockset along A-A to sectional view.

The specific embodiment (referring to Fig. 1), substrate 1 is made of two mutual bottom surface 1a and side 1b at an angle; There is an opening 2 at the middle part of bottom surface 1a, and two perforates 3 and 4 are arranged on the 1b of side, and through test of many times, perforate 3 and 4 is the best with rectangle or square.Moving plate 5 is actively connected on opening 2 one sides of bottom surface 1a with rotating shaft 6, and moving plate 5 can rotate within the specific limits around rotating shaft 6; On the moving plate 5 spring fixed column 51, dead bolt post groove 52, back stop slot 53, retaining flange 54 are arranged.When lockset was in opening as Fig. 1, retaining flange 54 was collided with perforate 3, thus the further rotation of resistance check plate 5.Check plate 7 is actively connected on opening 2 opposite sides of bottom surface 1a with rotating shaft 8, and check plate 7 can rotate within the specific limits around rotating shaft 8; Spring fixed block 71, locking tooth 72, spacing block set 73 are arranged on the check plate 7, and spacing block set 73 stretches in the perforate 4 of side 1b, and its restriction check plate 7 can only rotate in the length range of perforate 4.Between spring fixed column 51 and spring fixed block 71, be provided with spring 9.

(referring to Fig. 2), dead bolt post 10 is fixed on the vehicle body corresponding site, and whole door lock is placed on the car door.When being in closed condition, the locking tooth 72 on the check plate 7 inserts in the back stop slot 53 that moves on the plate 5; Because this moment, spring 9 opened (Fig. 2 does not draw, and is arranged between spring fixed column 51 and the spring fixed block 71), will move 7 tensions of plate 5 and check plate, thereby close dead bolt post 10 and reach an effect of closing.The interior hook 11 of dialling is actively connected on the 1b of side with rotating shaft 13 with the outer hook 12 of dialling, and interior group of hook 11 can rotate around rotating shaft 13 with outer group hook 12, and the front end of interior group of hook 11 and outer group hook 12 contacts with the spacing block set 73 of check plate 7 and can drive its and rotates; The interior pull bar (not drawing among the figure) of dialling hook 11 and inside door spanner links, and the pull bar (not drawing among the figure) of dialling hook 12 and outer catch outward links.

(referring to Fig. 3), Fig. 3 are sectional views of the present utility model.As the further improvement of the utility model structure, rotating shaft 6, rotating shaft 8, rotating shaft 13 are rivet; That is: moving plate 5 and check plate 7 flexibly connect with riveted way and bottom surface 1a, and interior group of hook 11 and the outer hook 12 of dialling flexibly connect with riveted way and side 1b.

Operating procedure: 1. during outward opening door, outer catch drives pull bar, the outer hook 12 of dialling of pull bar pulling, outer group hook 12 is stirred the spacing block set 73 of check plate 7, drive locking tooth 72 and in back stop slot 53, withdraw from, make check plate 7 break away from moving plate 5, thereby be returned to opening from closed condition.

2. during inward, interior catch drives pull bar, dials hook 11 in the pull bar pulling, and interior group of hook 11 stirred the spacing block set 73 of check plate 7.Below action is identical with the respective action of above-mentioned outward opening door, so omit.

When 3. closing, door lock on being placed in car door with car door turn to be fixed on the vehicle body corresponding site on dead bolt post 10 when contacting, the moving plate 5 of dead bolt post 10 collisions, enter in the dead bolt post groove 52, drive moving plate 5 and rotate, till the locking tooth 72 on check plate 7 inserts in the back stop slot 53 that moves on the plate 5.This moment, moving plate 5 and check plate 7 were tightened up because the tension force effect of spring 9, thereby closed dead bolt post 10 and reach the effect of closing door.
