Background technology
Lift control system is one of vitals of electric clothes airing machine, existing automatic airer majority reckons without overweight ultralight technical need, the possibility of particularly touching human body or touching with foreign object and meeting accident in clothes hanger decline process, even if the electronics mode of the electric clothes hanger many employings sensor having the overweight ultralight limit to detect realizes.But, adopt the electronics mode of sensor to realize the detection of the extreme position of jacking system and system control sytsem can be made to become very complicated for the overweight ultralight detection of system load and price is very expensive.In addition, the electric clothes hanger on balcony installed inevitably needs to bear humidity, high temperature, the working environment of dust storm, adopt the detection mode of sensor to reduce the reliability of control system, too increase the difficulty of debugging maintenance simultaneously when system jam.
Summary of the invention
The utility model object is that providing one mechanically to realize jacking system for the deficiencies in the prior art rises and in decline process, load is transfinited power-off protection function, when system load exceedes the rated value designed by jacking system, system realizes power-off protection immediately, system stops rising or declining, and anti-locking system is impaired because transshipping; When system load is lower than lowest threshold designed by jacking system, system realizes power-off protection immediately, and system stops rising or declining, and anti-locking system is subject to extra external loading interference and meets accident.
The utility model is achieved through the following technical solutions this object:
The overweight ultralight checkout gear of a kind of jacking system, comprise reel and the driving wheel for driving this reel to rotate, the periphery of described driving wheel is driving gear, middle part is for having the conductive reed of conducting function, described conductive reed is provided with the first insulation contact and the second insulation contact, described reel is provided with can with the first pin of reel synchronous axial system and the second pin, described conductive reed is also provided with some Compress Springs, be provided with a torsion spring between described conductive reed and reel, the two ends of described torsion spring are connected with conductive reed, reel respectively;
Wherein, when the load of jacking system is zero, the free end of described first pin between the first insulation contact and the second insulation contact, and touches with conductive reed, and the free end of the second pin also touches with conductive reed;
When the load of jacking system is for time negative, free end and second insulation contact of described first pin touch, and the first pin and the second pin are in off-state;
When the load of jacking system exceedes preset value, free end and first insulation contact of described first pin touch, and the first pin and the second pin are in off-state.
As preferably, described first pin and the second pin are extension type contact stitch, and described first pin and the terminals of the second pin are respectively used to be connected with two of control circuit binding posts.
Wherein, the quantity of described Compress Spring is three, and described three Compress Spring uniform intervals are distributed on conductive reed.
Relative to prior art, the beneficial effects of the utility model are: jacking system of the present utility model is overweight ultralight checkout gear, comprise two covers for carrying out the spring assembly of overweight, ultralight detection, be respectively overweight detection springs device and ultralight detection springs device, by controlling being turned on or off of binding post, according to the principle of relay switch, jacking system is controlled, realize the detection to overweight, ultralight state and disconnection protection; The utility model adopts mechanical overrun testing mode, on the one hand because the stability of mechanical structure and the uniqueness of motion process greatly improve system reliability, reduce the probability safeguarded and reprocess, on the other hand, the technical costs and equipment cost that adopt mechanical overrun testing to greatly reduce to realize this function, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the overweight ultralight checkout gear of jacking system of the present utility model.
In figure: 1-reel; 2-driving wheel; 21-conductive reed; 3-first insulation contact; 4-second insulation contact; 5-first pin; 6-second pin; 7-Compress Spring; 8-torsion spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, jacking system of the present utility model is overweight ultralight checkout gear, comprise reel 1 and the driving wheel 2 for driving this reel 1 to rotate, the periphery of described driving wheel 2 is driving gear, middle part is for having the conductive reed 21 of conducting function, described conductive reed 21 is provided with the first insulation contact 3 and the second insulation contact 4, described reel 1 is provided with can with the first pin 5 and the second pin 6 of reel 1 synchronous axial system, described first pin 5 and the terminals of the second pin 6 are respectively used to be connected with two of control circuit binding posts, two suitable relay switches of binding post, when two short-circuit of terminals conductings, the then corresponding conducting of drive circuit, drive motors works, jacking system performs descending operation, when two binding posts disconnect mutually, then the corresponding disconnection of drive circuit, motor quits work, and jacking system quits work.
Described conductive reed 21 is also provided with some Compress Springs 7, is provided with a torsion spring 8 between described conductive reed 21 and reel 1, and the two ends of described torsion spring 8 are connected with conductive reed 21, reel 1 respectively; When the load of jacking system is zero, the free end of described first pin 5 is between the first insulation contact 3 and the second insulation contact 4, and touch with conductive reed 21, the free end of the second pin 6 also touches with conductive reed 21, in this case, first pin 5 and the second pin 6 conducting, as long as switch on power then electric system work, drives reel 1 to rotate by driving wheel 2 and realizes lifting action;
When the load of jacking system is negative, namely time jacking system touches barrier and causes declining, described torsion spring 8 twists as ultralight detection springs device, described jacking system is under the effect of torsion spring 8, making the relative reel 1 of driving wheel 2 do circumference revolution makes the first pin 5 and the second insulation contact 4 touch, now namely cause the first pin 5 and the second pin 6 to be in off-state, can not there is lifting action in jacking system, play the function of ultralight protection;
When the load of jacking system exceedes preset value; namely when load is in overweight state; described Compress Spring 7 is had an effect as overweight detection springs device; the decrement of described Compress Spring 7 increases; make driving wheel 2 reel 1 circumference revolution relatively, the first pin 5 and the first insulation contact 3 are touched, causes the first pin 5 and the second pin 6 to be in off-state; can not there is lifting action in jacking system, play the function of overweight protection.
As preferably, described first pin 5 and the second pin 6 are extension type contact stitch, ensure that driving wheel 2 is arranged on after on reel 1, the contact of described first pin 5 and the second pin 6 can with conductive reed 21 close contact, reliable conducting.
Wherein, the quantity of described Compress Spring 7 is three, and described three Compress Spring 7 uniform intervals are distributed on conductive reed 21, and stress equalization, reliability are high.
The above embodiment only have expressed some embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
