DETAILED DESCRIPTION

[0022] The utility model will be further described below in combination with the drawings and examples.

[0023] As Figures 1 to 5 shown, the front view, rear view, left view, right view and top view of the fence door with added travel switch of the utility model are respectively given, Figure 7 and Figure 8 the perspective view thereof is given, Figure 6 the Figure 5 partial enlarged view of the A area in the figure is given, the fence door with added travel switch shown is composed of left stand 1, right stand 2, fence door 3, travel switch 6, electromagnetic lock 7 and baffle 8, fence door 3 is located between left stand 1 and right stand 2, the right side of fence door 3 is hinged on right stand 2 through a plurality of hinges 4, and the opening and closing of fence door 3 are realized by the rotation of fence door 3 around hinges 4 on right stand 2.

[0024] Switch support 5 is fixed on the rear side of left stand 1, travel switch 6 is fixed on switch support 5, touch rod 9 is arranged on travel switch 6, the end of touch rod 9 is provided with a roller, and the rotation of touch rod 9 can control the on-off state of the internal circuit of travel switch 6, that is, the swing of touch rod 9 can change the state of the normally open point and normally closed point inside travel switch 6. Baffle 8 is fixed on the rear side of fence door 3, and baffle 8 is used for cooperating with touch rod 9, when fence door 3 changes from the opening state to the closing state, baffle 8 pushes touch rod 9 to rotate, and then changes the state of travel switch 6.

[0025] Thus, by remotely monitoring the state of the normally open point or normally closed point of the travel switch 6, the opening and closing state of the fence door 3 can be monitored, so that the background data can directly show whether the fence door is closed or opened, and the safety of the running environment can be confirmed.

[0026] In order to realize good cooperation between the baffle 8 and the touch rod 9 on the travel switch 6, and avoid the baffle 8 directly shearing the touch rod 9 during the closing process of the fence door 3, the baffle 8 is composed of a straight plate part 11 and an inclined plate part 12. The inner end of the straight plate part 11 is fixed to the rear side of the fence door 3, and the inclined plate part 12 is fixed to the inner end of the straight plate part 11. In this way, during the movement of the baffle 8 with the fence door 3 towards the touch rod 9, the front end of the inclined plate part 12 first contacts the front end roller of the touch rod 9, and then gradually transitions to the straight plate part 11 contacting the touch rod 9, thereby playing a buffering role during the contact between the baffle 8 and the touch rod 9, and ensuring a longer service life of the travel switch 6.

[0027] The cross section of the switch bracket 5 is L-shaped, and the switch bracket 5 is fixed to the rear side of the left stand column 1 through a bracket bolt 10. Four long holes 13 for fixing the travel switch 6 are provided on the switch bracket 5. During use, by aligning the screw holes on the travel switch 6 with different positions of the long holes 13, the position of the travel switch 6 on the switch bracket 5 can be finely adjusted, and the distance between the baffle 8 and the touch rod 9 can be properly adjusted to avoid misoperation of the baffle 8 during the driving of the touch rod 9.

[0028] As shown in the enlarged view of the B region in FIG. 1, Figure 9 As shown in the enlarged view of the B region in FIG. 1, Figure 8 The front side of the left stand column 1 is fixed with a lock bracket 14, and the electromagnetic lock 7 is fixed on the lock bracket 14. The electromagnetic lock 7 is provided with a lock shaft 18, and the electromagnetic lock 7 can control the extension and retraction state of the lock shaft 18. The lock bracket 14 is provided with a bolt shaft 15, which can be displaced left and right by a certain amount. The bolt shaft 15 is fixed with a pin plate 17, and the pin plate 17 is provided with a through hole for inserting the lock shaft 18. The front side of the fence door 3 is fixed with an ear plate 16, and the ear plate 16 is provided with a through hole for inserting the bolt shaft 15.

[0029] During use, when the fence door 3 is closed, the bolt shaft 15 is inserted into the through hole in the ear plate 16, the pin plate 17 is flipped up, the lock shaft 18 of the electromagnetic lock 7 is inserted into the through hole of the pin plate 17, and at this time, the fence door 3 is locked, and it cannot be opened without authorized personnel operating the electromagnetic lock 7. Only authorized personnel can open the electromagnetic lock 7 to make the lock shaft 18 of the electromagnetic lock 7 retract, at which time the pin plate 17 is flipped down and the bolt shaft 15 is moved to the left to be pulled out of the through hole of the ear plate 16, and the fence door 3 can be opened.
