Abstract
The utility model discloses a breaking and anti-clamping triggering device of a swinging door in a passenger car, which comprises a triggering supporting frame (1), a travel switch (2), wherein the triggering supporting frame (1) is installed on the a cylinder piston rod (8), and is contracted through a nut (5), the travel switch (2) is connected with an air cylinder body (7) through a switch supporting frame (4), and the triggering surface where the triggering supporting frame (1) si contacted with the travel switch (2) is a radian surface. The utility model effectively solves a problem of unstable breaking and anti-clamping signals in the prior art. Simultaneously the utility model are further improved, the problems that a vehicle door is automatically opened because of false action, the travel switch has no protecting jacket, and the circuit dropping out which frequently appears in the running and the assembly are avoided. The structure of the utility model is simple, and the design is ingenious.
Description
Technical field
The utility model relates to a kind of disconnected anti-jamming device of car door, a kind of disconnected anti-jamming device that is used for inner swinging door of passenger train mechanism of saying so more specifically.
Background technology
Along with further developing of China's economic and city bus, the safety of passenger vehicle is more and more paid attention to.Necessity configuration that anti-jamming device becomes many public transport companies when purchasing car.And at present the reliability problems of anti-jamming device self has become the resistance of further popularization anti-pinch, and the reliability of anti-jamming device self is made of the accuracy of quality, the sensitivity of employing anti-jamming device inner components and the signal received.Present trigger switch device design as shown in Figure 2, its greatest drawback is because piston rod rotates among a small circle and causes support can not trigger travel switch, thereby cause car door closing when putting in place, take for and pressed from both sides and open car door, cause the serious potential safety hazard of bus door.Its greatest problem is that present switch bracket is plane, and narrower in width, only rotation need be arranged slightly, does not just have trigger switch, and in installation process as will break switch because of carelessness.Can cause again as untimely reparation to can not receive the anti-pinch signal,, in running and assembling, the circuit obscission often occur in addition because travel switch does not have protective jacket.
Summary of the invention
1. goal of the invention:
Unreasonable at the disconnected anti-jamming device design of existing inner swing door, trigger support and be plane, and narrower in width, only rotation need be arranged slightly, just there is not trigger switch, cause anti-jamming device to can not receive disconnected anti-pinch signal, and cause the car door misoperation, cause in potential safety hazard and running and the assembling problem that circuit comes off often to occur.The utility model provides a kind of inner swinging door of passenger train anti-pinch flip flop equipment that breaks, and can effectively separate the problem of making a decision the anti-pinch jitter.
2. technical scheme:
The technical solution of the utility model is as follows:
A kind of inner swinging door of passenger train anti-pinch flip flop equipment that breaks, comprise and trigger support, travel switch, trigger support and be installed on the cylinder piston rod, compress by nut, travel switch is connected with cylinder block by switch bracket, and the triggering face that the triggering support contacts with travel switch is the radian face.
Trigger support and adopt above-mentioned radian face structure, any point is very little to the variable in distance of travel switch on the feasible triggering support triggering face, also can not cause support to break away from the triggering travel switch even piston rod rotates among a small circle.Radian face structure main forms is fan-shaped or circular, oval.
The travel switch sheath is housed on travel switch, and the design of travel switch sheath can be a cuboid, also can be cylindric or other shapes.
The connected mode of triggering support and piston rod is mode directly or indirectly.
Operating principle of the present utility model is as follows: inner swing door mechanism is the cylinder piston rod retraction in the process of closing the door, and the triggering support that is contained on the piston rod triggers travel switch, and the travel switch signal passes to and disconnects anti-jamming device on the circuit control panel, and door-plate normally cuts out and puts in place.
3. beneficial effect:
The utility model discloses the disconnected anti-pinch flip flop equipment of a kind of inner swinging door of passenger train, effectively solved the problem of prior art interruption anti-pinch jitter.The while further improvement of the utility model has also effectively avoided car door to open automatically owing to misoperation and travel switch does not have protective jacket, the problem that circuit comes off often occurs in running and assembling.The utility model simple structure designs ingenious.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the prior art constructions schematic diagram;
Fig. 3 is that triggering support of the present utility model triggers the face structural representation.
