Abstract

Provided is an unlocking switch for a platform door, including a base body, a handle, a movement board, and a rotating shaft, the movement board is provided with long circular holes therein, a boss is arranged on the base body, the movement board is buckled on the boss of the base body through the long circular holes and specifies positions longitudinally. An unlocking rod is fixed at the upper end of the movement board and/or a steel wire rope is fixed at the lower end of the movement board, the handle is fixed on the base body via the rotating shaft and is provided with a protrusion, one can rotationally abut against the lower end of the movement board to enable the movement board to move upwards while unlocking. The unlocking switch provided has the advantages of simple structure, convenient and labor-saving operation and beautiful shape.

Description

A kind of gate is used unlock switch

Technical field

The utility model relates to the subway platform fitting of door, particularly a kind of concealed sliding door manual unlocking handle, and it can be used for local plug-type sliding door such as subway platform, railway platform.

Background technology

The existing subway gate is provided with hand-operating unlocking mechanism.Rotate wire rope or trip lever and operate release mechanism sliding door is carried out release thereby common handle is set as the one of which, in order to operate trip lever and wire rope simultaneously, the unlocking operation construction of switch of design is complicated, and operation effort and profile are not attractive in appearance.

Summary of the invention

The utility model technical problem to be solved is to provide a kind of gate to use unlock switch for the above-mentioned deficiency that overcomes prior art, makes it simple in structure, easy to operate.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of gate is used unlock switch, comprises matrix, handle, maneuvering board, rotating shaft, and slotted hole is set on the maneuvering board; Matrix is provided with boss; Maneuvering board is buckled on the boss of matrix and longitudinal spacing through the slotted hole on it, maneuvering board upper end fixed solution locking bar and/or lower end be wire rope fixedly, shakes hands to be fixed on the matrix through rotating shaft; Handle is provided with a projection, and rotation props up the lower end of maneuvering board and makes maneuvering board up during release.

During above-mentioned unlock switch release, rotate handle, maneuvering board moves upward at the guide pillar on the matrix under the driving of handle, when maneuvering board moves upward, can spur wire rope or promote trip lever, thereby realize sliding door is carried out manual unlocking.

Above-mentioned handle is arranged in the groove of matrix.

Compared with prior art, the advantage of the utility model is:

1. handle has constituted simple and reliable leverage at the handle end of rotating shaft one side and the projection of opposite side, utilizes lever principle to significantly reduce the manual unlocking power of sliding door door lock, and maneuvering board utilizes self gravitation to reset after the release, and is safe and reliable.

2. because handle is arranged in the groove of matrix, and handle is hidden in the matrix during therefore usual state, the part of exposing doorframe has seldom guaranteed the overall aesthetics of door body.

Description of drawings

Fig. 1 is the elevation of the utility model embodiment.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the lateral view of the utility model embodiment.

Fig. 4 is the released state figure of the utility model embodiment.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Like Fig. 1,2,3, shown in 4, a kind of gate is used unlock switch, comprises matrix 1, handle 2, maneuvering board 3, rotating shaft 7.

Two slotted

holes

31,32 are set on the maneuvering board 3; Matrix 1 is provided with two

boss

11,12; Maneuvering board 3 is buckled on the

boss

11,12 of matrix 1 through the slotted hole on it 31,32; And by pad 14 and screw 13 fixing and longitudinal spacings, maneuvering board 3 can move along the direction of slotted

hole

31,32 under the guiding of

boss

11,12 like this.

Maneuvering board 3 upper end fixed solution locking bars 5, the lower end is wire rope 6 fixedly.

Handle 2 is fixed on the matrix 1 through rotating shaft 7, and shaking hands like this 1 can be around rotating shaft 7 rotation.Handle 2 is provided with a projection 21, can prop up the lower end of maneuvering board 3 when rotateing in place, and sees Fig. 2, Fig. 3.

2 bottoms of shaking hands also are provided with locating part 21, and after the release, handle its locating part 21 of back that under action of gravity, resets props up matrix 1.

When needing release, pull handle 2, promote maneuvering board 3 through its projection 22 when handle 2 rotates and move upward.Thereby the wire rope 6 of trip lever 5 or lower end that drives connected upper end is up and carry out release, sees Fig. 4.

Bearing pin 4 also is set on the maneuvering board 3; Bearing pin 4 is fixing with revolution unlocking device (not drawing among the figure); The revolution unlocking device can be installed on the doorframe, like this can also can drive movement plate 3 through turning round unlocking device, thereby be implemented in platform side sliding door is carried out manual unlocking.

Claims
