For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of locking mechanism of three-bar blocking door and angular transducer, comprise barrier door body and bull stick, described bull stick is connected on the barrier door body by splined shaft, described splined shaft is provided with synchronous pulley, described synchronous pulley connection angle sensor, and described synchronous pulley is provided with barrier disc outward, the coaxial connection splined shaft of described barrier disc, the locking mechanism of described barrier disc connecting band electromagnet.
Locking mechanism of the present invention stops that by drawing together pawl and lock-bit electromagnet form, and the described pawl that stops is located at the lower end of barrier disc, and the described rear portion of pawl that stops connects the lock-bit electromagnet, and described lock-bit electromagnet is electrically connected with angular transducer.
Angular transducer of the present invention is made up of shell, correlation sensor, light barrier, rolling bearing and angular transducer axle, described angular transducer axle is located at the middle part in the shell, rolling bearing is located on the periphery footpath of angular transducer axle, and be positioned at shell, the middle part socket light barrier of described angular transducer axle, described correlation sensor is located at the two ends, a side left and right sides of light barrier, and described angular transducer axle is by the synchronous pulley of band connection synchronously.
Of the present invention stopping between pawl and the lock-bit electromagnet is provided with back-moving spring, and described back-moving spring one end is connected and stops on the pawl that the other end is connected on the barrier door body.
Barrier disc of the present invention is provided with corresponding grooves.
The present invention compared with prior art adopts the locking mechanism of special-purpose angular transducer and charged magnet, and plays the personnel of preventing by angular transducer control lock-bit electromagnet and trail the effect that enters, and has improved the reliability that three-bar blocking door uses.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of angular transducer of the present invention.
Fig. 3 is along the sectional view of A-A direction among Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, be structural representation of the present invention, three-bar blocking door comprises barrier door body 16, bull stick 10, described bull stick 10 is connected on the barrier door body 16 by splined shaft 7, is connected with synchronous pulley 6 on the described splined shaft 7, is provided with angular transducer 9 on a side of synchronous pulley 6, described angular transducer 9 is by being with 5 to be connected with synchronous pulley 6 synchronously, the splined shaft 7 coaxial barrier discs 4 that are provided with, barrier disc 4 is positioned at outside the synchronous pulley 6, and described barrier disc 4 is provided with corresponding grooves 41.
The lower end of barrier door body 16 is provided with the locking mechanism 17 of charged magnet, and locking mechanism 17 stops that by stopping that pawl 3 and lock-bit electromagnet 1 form pawl 3 one ends are coupling on barrier door body 16, the groove 41 corresponding settings on the other end and the barrier disc 4.Be provided with lock-bit electromagnet 1 in the rear end that stops pawl 3, in lock-bit electromagnet 1, promote to stop that by telescopic push rod pawl 3 stops that barrier disc 4 rotates, be provided with back-moving spring 2 in the lower end that stops pawl 3, an end of back-moving spring 2 is connected and stops that on the pawl 3, the other end is connected on the barrier door body 16.
When uncommitted personnel want to go to promote bull stick 10 by barrier door, angular transducer 9 sends signal command to lock- bit electromagnet 1,1 action of lock-bit electromagnet, promote forward to stop that pawl 3 enters barrier disc 4, barrier disc 4 is lockable, thereby make the traffic cycle and the bull stick 10 that are attached thereto be lockable and to rotate, reach the current purpose of effective prevention.
As shown in Figures 2 and 3, structural representation for angular transducer of the present invention, described angular transducer 9 is made up of shell 15, angular transducer axle 11, rolling bearing 12, correlation sensor 13 and light barrier 14, angular transducer axle 11 is located at the middle part in the shell 15, rolling bearing 12 is located on the periphery footpath of angular transducer axle 11, and be positioned at shell 15, the middle part socket light barrier 14 of angular transducer axle 11.Described correlation sensor 13 is located on the shell 15 at two ends, the light barrier 14 1 side left and right sides, and angular transducer axle 11 is by being with 5 to connect synchronous pulley 6 synchronously.
The operating principle of locking mechanism function of the present invention is: when nobody passed through barrier door, the bull stick 10 of barrier door resetted and is in zero-bit, and at this moment, correlation sensor 13 is in opening; When uncommitted personnel promoted bull stick 10 by barrier door, bull stick 10 can drive the traffic cycle, splined shaft 7, angular transducer axle 11 and the light barrier 14 that are attached thereto and rotate; The angle of rotating when bull stick 10 is during greater than 5 °, correlation sensor 13 is intercepted becomes off-state by opening, the very fast signal with identification of angular transducer 9 gives the lock-bit electromagnet 1 its action of instruction, promote forward to stop that pawl 3 enters barrier disc 4, barrier disc promptly is lockable, thereby make the traffic cycle and the bull stick 10 that link to each other by splined shaft 7 with it also be lockable and can not rotate, uncommitted personnel can not pass through, thereby have reached the purpose that effectively stops.If the authorized person passes through barrier door, lock-bit electromagnet 1 power-off restoration under the effect of back-moving spring 2 pulling force, stops that pawl 3 resets, and throws off with barrier disc 4, can promote the barrier door bull stick and have free passage.
