Abstract
The utility model relates to a limit switch collision avoidance mechanism belongs to electrical equipment technical field. Including limit switch, supporting base, supporting spring and spring bracket, limit switch is fixed in and supports the base upper surface, supporting spring upper end and support under base surface fixed connection, and the lower extreme is fixed with spring bracket. The utility model discloses when limit switch received the striking of connecting rod or baffle, supporting spring took place to warp, made limit switch and support the base to take place the displacement to slow down the impact that limit switch received, effectively protect limit switch, simultaneously, when supporting base emergence displacement, can compress ascending any the location spring of other three side, after external force was removed, the location spring can the set back to make that limit switch can be accurate get back to the origin -location on, like this the limit switch detection can not receive a bit influence. The utility model discloses effectively prolong limit switch life, guaranteed normal production, and simple structure, low cost, broad prospect promoted.
Description
Technical field
This utility model relates to a kind of limit switch Anti-bumping protection mechanism, belongs to technical field of electric equipment.
Background technology
Limit switch is the common part in electrical equipment, and limit switch is typically mounted at the front end of the positions such as pneumatic operated valve, cylinder, baffle plate, is used for detecting the location status of the equipment such as pneumatic operated valve, cylinder, baffle plate, thus forms feedback signal, and display is on computer picture.Limit switch is damaged accident the most often, analysis reason is: first, limit switch is in order to accurately detect the location status of valve body, limit switch and detected body are apart from close, it is generally less than 2cm, if slightly remote, can't detect detected body position, so in actual production process, limit switch is easy to be bumped against；Secondly, the action of pneumatic operated valve, cylinder etc. is to be filled with compressed air by cylinder body two ends, drive connection bar action under pressure, during actual motion, owing to gas injection rate is unbalanced, cylinder leakage tester, connecting rod action be dumb etc., and reason all can make connecting rod track route offset, once offset, connecting rod top is easy to bump against limit switch, owing to compressed air pressure is the highest, the strength causing cylinder to promote connecting rod to move is the biggest, limit switch is once clashed into by connecting rod top, clashes into and limit switch once can be caused thoroughly to damage.After limit switch is damaged, PLC system finds that limit switch does not has feedback signal, does not allow to directly result in mediation in startup correlation timing or sequential running, thus impacts whole production.Therefore, in order to preferably protect limit switch, it is necessary to a kind of limit switch anticollision protection mechanism of design.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of limit switch Anti-bumping protection mechanism, can significantly slow down impact suffered after limit switch is knocked, effectively protect limit switch.
The technical scheme solving above-mentioned technical problem is:
A kind of limit switch Anti-bumping protection mechanism; including limit switch, its improvements are: it also includes supporting base, supporting spring and spring support, and limit switch is fixed on support base upper surface; support spring upper end is fixing with support base lower surface to be connected, and lower end is fixed with spring support.
Above-mentioned a kind of limit switch Anti-bumping protection mechanism, described limit switch with support base fixing after, limit switch contact head with support base leading flank homonymy；It also includes left location spring, right location spring, positions spring, left fixed dam, right fixed dam and rear fixed dam afterwards, left location both ends of the spring is fixed with support chassis left side face and left fixed dam respectively, right location both ends of the spring is fixed with support base right flank and right fixed dam respectively, and rear location both ends of the spring is fixed with support base trailing flank and rear fixed dam respectively.
This utility model, when limit switch is clashed into by connecting rod or baffle plate, supports spring and deforms, and makes limit switch and support base be subjected to displacement, thus slows down limit switch impact, effectively protects limit switch；Meanwhile, when supporting base and being subjected to displacement, any one the location spring on the other three direction can be compressed, after external force releases, location spring can set back, so that limit switch can accurately return on origin-location, the detection of such limit switch will not at all be affected.
The beneficial effects of the utility model are:
This utility model is not while effectively protection limit switch is damaged, it is ensured that limit switch accurately returns to origin-location after being knocked and carries out normal signal detection, does not affect it and normally uses.This utility model effectively extends limit switch service life, it is ensured that normally produce, and simple in construction, with low cost, and promotion prospect is wide.
Accompanying drawing explanation
Fig. 1 is this utility model front view；
Fig. 2 is this utility model right side view；
Figure is labeled as: limit switch 1, support base 2, support spring 3, spring support 4, left location spring 5, right location spring 6, afterwards location spring 7, left fixed dam 8, right fixed dam 9, rear fixed dam 10, connecting rod 11, limit switch contact head 12.
Detailed description of the invention
Fig. 1 and Fig. 2 shows; this utility model one limit switch Anti-bumping protection mechanism, including limit switch 1, supports base 2, supports spring 3, spring support 4, left location spring 5, right location spring 6, rear location spring 7, left fixed dam 8, right fixed dam 9 and rear fixed dam 10；Limit switch 1 is fixed on the upper surface supporting base 2, after limit switch 1 is fixing with support base 2, and limit switch contact head 12 and the leading flank homonymy supporting base 2；The lower surface of the upper end and support base 2 that support spring 3 is fixed and is connected, and lower end is fixed with spring support 4；Spring 5 two ends, left location are fixed with the left surface and left fixed dam 8 supporting base 2 respectively, spring 6 two ends, right location are fixed with the right flank and right fixed dam 9 supporting base 2 respectively, and spring 7 two ends, rear location are fixed with the trailing flank and rear fixed dam 10 supporting base 2 respectively.
This utility model, when limit switch 1 is by the shock of connecting rod 11, supports spring 3 and deforms, and makes limit switch 1 and support base 2 be subjected to displacement, thus slows down limit switch 1 impact, effectively protection limit switch 1；Meanwhile, when supporting base 2 and being subjected to displacement, any one the location spring on the other three direction can be compressed, after external force releases, location spring can set back, so that limit switch 1 can accurately return on origin-location, the detection of such limit switch 1 will not at all be affected.
