Abstract
The utility model relates to a limit device provided with spring restoration, which is characterized in that: the device comprises a magnetic limit switch fixedly arranged on a frame, a piece of magnet in corresponding arrangement with the magnetic limit switch and a guide rod which is fixedly connected with the magnet and can go through, in a sliding manner, a fixing bracket I and a fixing bracket II which are fixedly connected with the frame and is fixedly connected with a forwards extending baffle; the guide rod is sheathed with an elastic part which is clamped and pressed by the fixing bracket I and the guide rod. The device is safe and reliable and has simple structure and long service life.
Description
Technical field
The utility model relates to a kind of limit switch device, particularly a kind of stopping means with spring reset.
Background technology
At present, the limit switch device that is used for cooked rice producing line adopts seal mechanical limit switch mode preferably mostly.Because the high humidity of the operation element environment of cooked rice producing line, limit switch device switch is frequent, just needs this device to satisfy reliable, safe job requirement.Though adopt seal mechanical limit switch preferably, long-time frequent switch must cause the sealing property of mechanical limit switch aging, thereby there is potential safety hazard in the reliability of its work and security more.
Summary of the invention
The utility model provides a kind of simple in structure, safe and reliable, the stopping means of the band spring reset of long service life for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of stopping means with spring reset, comprise the magnetic limit switch that is packed on the frame, magnet with the corresponding setting of described magnetic limit switch, the guide post affixed with described magnet, it is affixed with the baffle plate that protracts that described guide post passes the fixed support I affixed with frame, fixed support II slidably, suit elastomeric element on described guide post, described elastomeric element is by described fixed support I and described guide post cramping.
The utility model can also adopt following technical scheme:
Described guide post is two.
The elastomeric element of suit is the compression spring on the described guide post.But be not limited only to this, can be with replacements such as compressible other resilient sleeve parts.
Described magnet is column type magnet.
Advantage and the good effect that the utlity model has are: simple in structure, safe and reliable because the utility model has adopted magnetic limit switch, and long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the utility model comprises the magnetic limit switch 1 that is packed on the frame, magnet 2 with described magnetic limit switch 1 corresponding setting, the guide post 5 affixed with described magnet 2, it is affixed with the baffle plate 6 that protracts that described guide post 5 passes the fixed support I 3 affixed with frame, fixed support II4 slidably, suit elastomeric element 7 on described guide post 5, described elastomeric element 7 is by described fixed support I3 and described guide post 5 crampings.
Described guide post 5 is two
The elastomeric element 7 of suit is the compression spring on the described guide post 5.
Described magnet 2 is column type magnet.
The course of work that the utility model is used for cooked rice producing line is as follows:
The rice steamer collision baffle plate 6 that protracts of the present utility model, the baffle plate 6 that protracts is pushed the displacement forward of compression spring 7, protract simultaneously also displacement forward of guide post 5 on the baffle plate 6, guide post 5 is affixed with column type magnet 2, this moment, column type magnet 2 was near the fixing magnetic limit switch 1 of the other end, when the switch that satisfies magnetic limit switch 1 and column type magnet 2 apart from the time, the reed switch contact action of magnetic limit switch 1, outwards send the switching signal, but this signal device for switching.
After the rice steamer leaves, the baffle plate 6 spring 7 reaction force homings by compression of protracting, column type magnet 2 leaves magnetic limit switch 1, and the switching signal is outwards sent in the reed switch contact action of magnetic limit switch 1, but this signal device for switching.
