Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to a kind of rolling screen door dibit travel switch.
Background technology
Electric rolling door is used widely in the place such as StoreFront, garage, can be automatically stopped when electric rolling door is elevated to precalculated position, this function is completed by caging device for rolling shutter door, existing caging device for rolling shutter door is typically by the gear driven screw rod rotation connected with door roller drive mechanism, make the slide block on screw rod axially move and touch travel switch, travel switch sends the signal of telecommunication, thus stops door roller and run.Travel switch typically has two, and one is used for limiting opening position, and another is closed the door position for restriction.After use after a while, the often ablation of travel switch internal electrical contact and cause travel switch malfunctioning, cause up can not the stopping of rolling screen door and rush to summit or descending can not stop and colliding surface, therefore, the most a lot of caging device for rolling shutter doors all again in the outside of original travel switch more is provided with a travel switch, cause the accident in case original travel switch is malfunctioning, the mounting structure within stop to be changed, also add expense.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that one has travel switch function and can prevent rolling screen door from rushing to summit or hit ground, compact conformation, lower-cost rolling screen door travel switch.
This utility model is achieved through the following technical solutions:
A kind of rolling screen door dibit travel switch, including housing and switches set；Described housing is hollow structure, and housing is provided with installing hole, and housing top and the bottom are equipped with square pilot hole；Described switches set is provided with depression bar, conductive contact blade, pin, back-moving spring and movable driving lever；Can freely up and down slide in being through pilot hole in described depression bar two ends, its two ends shape, size and pilot hole match, and hull outside is located on this depression bar top；Described conductive contact blade is fixed in the middle part of depression bar, and its two ends upper surface is provided with lower contact；Described pin is provided with a pair, and enclosure interior is located in its one end, and end lower surface is provided with upper contact, and this upper contact is positioned at directly over lower contact, and the pin other end is located at hull outside；Described back-moving spring is enclosed within outside depression bar to be located at below conductive contact blade, presses lower housing portion, upper end pushing and withstanding conductive contact blade to make lower contact and upper contact normally closed under its lower end；Described movable driving lever is located on the upside of hull outside, and its one end and housing connect, and the other end is located at depression bar top end；Described switches set is separated by side by side and is provided with two groups.During use, being arranged in caging device for rolling shutter door by installing hole by this utility model, pin connects door roller controller；During work, when the slide block on the screw rod of caging device for rolling shutter door moves axially the movable driving lever touching left-side switch group, under movable driving lever, moulded rod moves downward, make the normally closed upper contact of switches set, lower contact separately, thus cut off the electrical connection of two pins, door roller controller, according to the power-off signal of two pins, controls door roller out of service；After slide block leaves movable driving lever, back-moving spring promotes conductive contact blade to move upward, and makes lower contact and upper contact recover normally closed；When this switches set breaks down, door roller does not shut down, and the slide block of stop may proceed to move right, and touches right-side switch group, and right-side switch group can be cut off the electrical connection of two pins equally, so that door roller is out of service, shield.
Preferably, described housing is square.Square casing is easy to be set up in parallel two switches set.
Preferably, described installing hole is provided with two.For travel switch being firmly installed on stop base.
Preferably, described upper contact, the material of lower contact are argent.Argent contact is difficult to ablation.
Preferably, described movable driving lever is spring leaf, and this spring leaf end is upwards bent into arch.Spring leaf is prone to movable and resets；Spring leaf end is upwards bent into arch for making spring leaf flex outward, it is simple to stir.
The beneficial effects of the utility model are: are separated by side by side in enclosure interior and arrange two switches set, after a switches set is malfunctioning, another switches set shield, prevent rolling screen door from rushing to summit or hit ground；Two switches set are all located in same housing, do not interfere with the inner mounting structure of door roller stop, not only have the function of travel switch, moreover it is possible to preventing rolling screen door from rushing to summit or hit ground, compact overall structure, cost is relatively low.
Compact conformation, expense is relatively low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
As it is shown in figure 1, embodiment of the present utility model, including housing 1 and switches set；Described housing 1 is hollow structure, and housing 1 is provided with installing hole 2, and housing 1 top and the bottom are equipped with square pilot hole 3；Described switches set is provided with depression bar 4, conductive contact blade 5, pin 6, back-moving spring 7 and movable driving lever 8；Can freely up and down slide in being through pilot hole 3 in described depression bar 4 two ends, its two ends shape, size and pilot hole 3 match, and it is outside that housing 1 is located on this depression bar 4 top；Described conductive contact blade 5 is fixed in the middle part of depression bar 4, and its two ends upper surface is provided with lower contact 9；Described pin 6 is provided with a pair, and it is internal that housing 1 is located in its one end, and end lower surface is provided with upper contact 10, and this upper contact 10 is positioned at directly over lower contact 9, and it is outside that pin 6 other end is located at housing 1；Described back-moving spring 7 is enclosed within outside depression bar 4 to be located at below conductive contact blade 5, and under its lower end pressure shell body 1 bottom, upper end pushing and withstanding conductive contact blade 5, makes lower contact 9 and upper contact 10 normally closed；Described movable driving lever 8 is located at housing 1 external upper, its one end and housing 1 and is connected, and the other end is located at depression bar 4 top end；Described switches set is separated by side by side and is provided with two groups.During use, being arranged in caging device for rolling shutter door by installing hole 2 by this utility model, pin 6 connects door roller controller；During work, when the slide block on the screw rod of caging device for rolling shutter door moves axially the movable driving lever 8 touching left-side switch group, movable 8 times moulded rods 4 of driving lever move downward, making the normally closed upper contact 10 of switches set, lower contact 9 separately, thus cut off the electrical connection of two pins 6, door roller controller is according to the power-off signal of two pins 6, control door roller out of service, after slide block leaves movable driving lever 8, back-moving spring 7 promotes conductive contact blade 5 to move upward, and makes lower contact 9 and upper contact 10 recover normally closed；When this switches set breaks down, door roller does not shut down, and the slide block of stop may proceed to move right, and touches right-side switch group, and right-side switch group can be cut off the electrical connection of two pins 6 equally, so that door roller is out of service, shield.
