With the illustrated structure, the side of the slide bar 3 close to the groove 10 in the present embodiment is the portion of the slide bar 3 located above the slider 2 in the figure, and the side of the slide bar 3 away from the groove 10 is the portion of the slide bar 3 located below the slider 2 in the figure.
The working process of the one-way belt locking in-place feedback mechanism provided by the invention is elaborated by taking the example that a certain movable object moves along a fixed track and needs to perform in-place feedback after the object moves in place.
When the moving object 15 in fig. 1 moves upward to a certain position, the sliding element 2 moves rightward under the action of the first elastic element 11, and when the groove 10 on the sliding element 2 partially moves to the opening 7 of the sliding rod 3, the sliding rod 3 also moves downward under the action of the second elastic element 6. The slide rod 3 is clamped at the groove 10 part of the slide part 2 after moving, the slide part 2 is prevented from moving, so that the moving object 15 is locked and stably kept in the moving-in-place state, meanwhile, the pressure welding piece 8 of the slide rod 3 touches the touch switch 13, the touch switch 13 starts the alarm device 4 to give an alarm, and when the slide part 2 reaches the second position, the state of the whole mechanism after moving in place is shown in fig. 2.
As shown in fig. 3, the rightmost object in the figure can move upward along a track on which the position feedback mechanism proposed herein is mounted.
The moving object 15 is a cuboid, and the track is also similar to a cuboid.
The slider in the position feedback mechanism can be designed into the shape shown in fig. 4, the right end of the slider is designed into a square shape so as to lock the moving object, and meanwhile, a square opening is formed in the track to be matched with the slider in a locking mode. The remaining portion of the slider may be designed as a cylinder for facilitating engagement with the first resilient member or the remaining structural portion. The cylindrical rod portion of the slider is provided with a groove having a shape to be engaged with the rod member, here, for example, the groove is semicircular in shape as shown in a-a section in fig. 4.
The slide bar may be shaped as shown in fig. 5, with a crimp at the lower end of the slide bar for actuating the microswitch, the remainder being designed as a cylinder for facilitating engagement with the second resilient member or the remainder of the structure, and the middle portion having a hole (in this case, a slotted hole) for engagement with the slider.
When the moving object in the figure 3 moves upwards to the proper position, the sliding part of the proper position feedback mechanism springs out of the sliding part extending guide rail rightwards under the action of the first elastic part, so that the movable object is prevented from moving reversely, and meanwhile, the groove on the sliding part reaches the position of the opening on the sliding rod. Then the sliding rod moves downwards under the action of the second elastic piece, and the pressing piece at the lower end of the rod piece triggers the micro switch.
And finally, the microswitch starts an alarm device to give an alarm so as to feed back an in-place signal.
It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations or modifications may be made on the basis of the above description, and all embodiments may not be exhaustive, and all obvious variations or modifications may be included within the scope of the present invention.
