The specific embodiment
In order to make those skilled in the art person understand better the present invention program, the present invention is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1 to Fig. 3, the invention provides a kind of subway safe door electromagnetic lock, comprise firm banking 10, the rear end of described firm banking 10 is fixedly installed main support 20, and described main support 20 front upper are fixedly installed top mounting bracket 30.
Need to prove, two ingredients that described main support 20 and described top mounting bracket 30 can same supports, namely described main support 20 and described top mounting bracket 30 can be an integrally formed integral body,
In the present invention, referring to Fig. 3, Fig. 4, the bottom center position of described top mounting bracket 30 is provided with the spring 1 of a screw type, described spring 1 bottom is fixedly connected with 2 tops that take off post, described 2 bottoms that take off post are fixedly connected with a transmission bracket 3(and are specifically as follows described transmission bracket 3 and are enclosed within on described 2 outer walls that take off post), the bottom centre position of described transmission bracket 3 is fixedly connected with the top of a lock 4, and described lock 4 runs through described firm banking 10 processus aboralis for the bottom surface of described firm banking 10.
In the present invention, for the metro safety door locked that realizes electromagnetic lock is installed, has lockhole under described lock 4, described lockhole is positioned at platform to be locked (for example subway platform ground) top or the surface-mounted fixed gate arch of subway platform, certainly can also be other permanent positions, the shape of described lockhole, size and the shape of described lock 4, big or small corresponding coupling.
referring to Fig. 4, the two ends, left and right of described transmission bracket 3 have respectively a support arm 5, the iron core construction opening 6 that has a cross direction profiles on each support arm, in the lump referring to Fig. 1, each described iron core construction opening 6 is fixedly connected with an iron core 7, the top of each described iron core 7 is fixedly connected with the bottom of the electromagnetic coil 8 of the rear adsorbable iron core that powers on, described two electromagnetic coils 8 (are that described electromagnetic coil 8 is threaded with described main support 20 by the two ends, positive left and right that four bolts 80 are fixedly installed in described main support 20 respectively, certainly, can also be other fixed form, for example clamping).
On specific implementation, referring to Fig. 4, described iron core construction opening 6 is preferably the opening that is " U " font.In addition, according to user's needs, can also be designed to the opening of other shapes, be for example rectangle.
Referring to Fig. 1, Fig. 3, Fig. 4, described 2 fronts that take off post are provided with a mounting frame for sensor 40, the left and right sides at described mounting frame for sensor two ends Shang Xia 40 is separately installed with a pair of the first photoelectric sensor 41 and a pair of the second photoelectric sensor 42, and described the first photoelectric sensor 41 and the second photoelectric sensor 42 are for detection of the lock-out state of electromagnetic lock of the present invention.
Need to prove, the original state of electromagnetic lock of the present invention is lock-out state, when the second photoelectric sensor 42 that is positioned at mounting frame for sensor 40 bottoms is blocked, the output locking closes signal, after electromagnetic lock powers on, electromagnetic coil 8 picks up iron core 7, iron core 7 drives locks 4 by transmission bracket 3 and realizes lock 4 is lifted, and the first photoelectric sensor 41 that at this moment is positioned at mounting frame for sensor 40 tops is blocked and exports the lock start signal; After the electromagnetic lock dead electricity, under the elastic force effect of spring 1, lock 4 is rebounded, electromagnetic lock resets.
For subway safe door electromagnetic lock provided by the invention, compare with existing electromagnetic lock, the present invention has not only increased the number of electromagnetic coil and iron core, to increase the power that lock is lifted; Simultaneously, also further improved the transmission bracket 3 that is used for lifting lock 4, transmission bracket 3 is designed to have respectively at the two ends, left and right the support arm 5 of iron core construction opening, the global shape of transmission bracket 3 is symmetrical "Ji" type, thereby after electromagnetic lock powers on, two electromagnetic coils 8 pick up an iron core 7 respectively, under the suction of electromagnetic coil 8, two iron cores 7 that are fixedly connected with the two ends, left and right of transmission bracket 3, can be positioned at the middle lock 4 of transmission bracket 3 by transmission bracket 3 drives, make lock 4 move upward.at this moment, due to the left and right sides of lock 4 be subject to the upper pulling force equal and opposite in direction, and be all the pulling force on vertical direction, so two ends, left and right stress equalization of lock 4, make the lock 4 can be steady, vertically be lifted from lockhole, and guarantee can not rub with the lockhole sidewall, therefore, the present invention can allow lock 4 lift swimmingly and under drop in lockhole, avoid safety door normally to open and to lock, the situation that " card pauses " or " stuck " can not occur, can greatly extend the application life of electromagnetic lock, reduce the use cost of safeguarding of subway safe door.
In addition, for subway safe door electromagnetic lock provided by the invention, for the size that guarantees electromagnetic lock is suitable, two pairs of photoelectric sensors are placed on the centre position of whole electromagnetic lock, the dismounting flow process when further having simplified the electromagnetic lock cleaning.
Need to prove, for subway safe door electromagnetic lock provided by the invention, it efficiently solves original electromagnetic lock in use multiple " card " and " stuck " problem, makes the adhesive of lock and whereabouts smooth and easy.Simultaneously, this electromagnetic lock Design of Mechanical Structure is reasonable, adopts the symmetrical expression design, and modular construction simply is easy to process, disassemble, clean, and is installed on convenient disassembly.In addition, when former electromagnetic lock broke down, the fault on its frame for movement (transmission bracket distortion), can't complete local maintenance often, and the design of electromagnetic lock of the present invention on its frame for movement is very reasonable, has reduced greatly this type of fault; In addition, the price of buying former factory electromagnetic lock is very expensive, and this electromagnetic lock belongs to the production domesticization product, and is cheap.
In sum, compared with prior art, the invention provides a kind of subway safe door electromagnetic lock, it is simple and reasonable for structure, can safely and reliably the lock in electromagnetic lock be lifted and under drop in lockhole, guarantee on subway platform normal the unlatching and the locked secure door, be conducive to improve quality and the operating efficiency of electromagnetic lock, extend the application life of electromagnetic lock, be of great practical significance.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
