Description

Hand-control mechanical automatic door closing mechanism

The utility model is an a kind of manual mechanical type automatic opening and closing door mechanism, belongs to door opening/closing apparatus.

At present, the passenger door opening and closing are to adopt the electromagnetic pneumatic device.But car or little wagon etc. all do not have the device of automatic switch car door.The switch car door of existing car and little wagon, by passenger's switch car door of doing it yourself, especially the passenger gets off suddenly, can run into the back and send a car and hit tail gate, and the wounded accident of passenger can happen occasionally.

For fear of the problem of above-mentioned existence, the purpose of this utility model is to be better passenger services, makes the passenger when getting on or off the bus, but the car door automatic switch, so the device of an automatic switch car door is set on car door.

The utility model is achieved in that holding rod, U type connecting rod, adjusting rod, guide plate, push pedal, movable rotating plate, junction plate, steel wire and joint etc., connected to form manual mechanical type automatic opening and closing door mechanism successively.Junction plate is packed on the appropriate location, lower left of right back door in the car, the U type linkage of transmission mechanism is on the chassis of driver's cabin, and joint links to each other with the dead bolt of car door lock.During use, when holding rod pushes away forward, U type connecting rod is through adjusting rod, push pedal is displacement forward, and promotion activity rotating plate is done limited being rotated counterclockwise around round pin, this moment, steel wire pulled down the dead bolt of driving door lock, make dead bolt slowly leave the snap lid of lock body, when the screw on the curved jaw of adjusting rod moves on the right-hand member limit that comes to microscler elliptical aperture, push pedal stops displacement, then the dead bolt of car door lock all withdraws from snap lid and promptly locks and be opened, and meanwhile back-moving spring is stretched, at this moment, curved jaw continues displacement forward, and promote guide plate and move, because guide plate is a rigid connection with car door, certainly will make car door along with mobile and slowly outwards open car door, when holding rod is pushed forward to the end, then car door is all opened.When holding rod resetted backward, the sequence of movement when its transmission work pushes away forward with holding rod was opposite, promptly finishes closed door.The pitch-row of microscler elliptical aperture is a bit larger tham dead bolt and is left the snap lid distance.The corner that pushes away before the holding rod is identical with the corner of car door opening.

Technique effect of the present utility model: the driver can manipulate the switch of car door directly, need not passenger's switch car door in person, makes things convenient for the passenger, and has guaranteed passenger's safety up and down; This mechanism structure is simple, operates nimble, accurate, safe and reliable, low cost.

The utility model can also obtain further instruction from the following drawings and embodiment.

Fig. 1 is a perspective view of the present utility model.

Fig. 2 is a stereochemical structure A of the present utility model portion enlarged diagram.

Drawing numbering: 1-holding rod, 2-U type connecting rod, 3,4,12-semi-ring piece, 5, the 18-screw, 6,11,24, the 25-circular hole, 7-adjusting rod, 8-guide plate, the 9-back-moving spring, 10-push pedal, the movable rotating plate of 13-, the 14-junction plate, 15-sleeve pipe, 16-steel wire, the 17-joint, the microscler elliptical aperture of 19-, 20-positioning sliding block, the 21-cylinder, 22-adjustment screw, 23-round pin.

Below in conjunction with accompanying drawing, embodiment describes in detail to the utility model.

The utility model is an a kind of manual mechanical type automatic opening and closing door mechanism, is made up of transmission and fixed part.Fixed part: comprise junction plate 14 and guide plate 8; On a section of guide plate 8, be provided with microscler elliptical aperture 19; Junction plate 14 is provided with two guide plates 8, and both are and are parallel to each other and certain spacing is arranged; Being equipped with semicircle piece 12 on sleeve pipe 15 1 ends is packed on the junction plate 14 by screw; On junction plate 14, also have cylinder 21 and circular hole 11.Drive disk assembly: comprise holding rod 1, U type bar 2, adjusting rod 7, push pedal 10, movable rotating plate 13, back-moving spring 19, adjustment screw 22 and steel wire 16.Movable rotating plate 13 usefulness round pins 23 link to each other with junction plate 13; Steel wire 16 passes through sleeve pipe 15, and the one end is connected with joint 17, and the other end passes the circular hole on movable rotating plate 13 tops, and adjustment screw 22 is housed on this end; Between the circular hole of the cylinder 21 of junction plate 14 and movable rotating plate 13, back-moving spring 9 is housed; Push pedal 10 1 ends are provided with a circular hole 25, on the section positioning sliding block 20 are housed therein, and push pedal 10 places on the upper guide plate 8, and the positioning sliding block 20 on the guide plate 8 is fastened on the upper guide plate 8 one side inner concave edge; The curved jaw of adjusting rod 7 is sleeved on the straight jaw of guide plate 8, and passes circular hole on the curved jaw, elliptical aperture 19 and circular hole 25 with screw 18 three is fused; U type connecting rod 2 one ends insert in the straight jaw of adjusting rod 7, are connected with screw 5, and holding rod 1 is housed on its other end.
