DETAILED DESCRIPTION
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0017] As shown Figures 1 to 3 in the figure, a safety anti-falling box mechanism of a preferred embodiment is shown, including:
[0018] A turning frame 1, a locking cylinder 2, a proximity switch 3, a safety lock claw 4, a travel switch 5, a limit beam 6 and an audible and visual alarm. The turning frame 1 has two longitudinal beams 12, and the two longitudinal beams 12 are arranged in parallel. The locking cylinder 2 and the audible and visual alarm are both installed on one side of one longitudinal beam 12. One end of the output shaft of the locking cylinder 2 passes through the other side of this longitudinal beam 12. The proximity switch 3 is installed at one end of the output shaft of the locking cylinder 2. One end of the safety lock claw 4 is rotatably installed on the other side of this longitudinal beam 12. The travel switch 5 is installed on the other side of this longitudinal beam 12. The travel switch 5 is used to monitor the position of the safety lock claw 4. The lower surface of the limit beam 6 is slidably installed on the upper surfaces of the two longitudinal beams 12. The limit beam 6 is connected to a garbage container, and the garbage container operably drives the limit beam 6 to move along the length direction of the two longitudinal beams 12. A hook groove 11 is provided on the upper surface of the safety lock claw 4, and the hook groove 11 operably locks the limit beam 6. The output shaft of the locking cylinder 2 operably abuts against the lower surface of the safety lock claw 4. The proximity switch 3 is connected to the audible and visual alarm.
[0019] During the actual use process, when the limit beam 6 moves away from the safety lock claw 4, the safety lock claw 4 is in a hanging state under the action of its own weight. As the garbage container advances, it drives the limit beam 6 to gradually approach and drives the safety lock claw 4 to rotate. At this time, due to the block of the safety lock claw 4, the locking cylinder 2 cannot extend. In this state, the output shaft of the locking cylinder 2 does not drive the proximity switch 3 to move and trigger a signal, and the audible and visual alarm emits a voice signal of "container not locked". When the garbage container drives the limit beam 6 to move to a certain position, at this time the limit beam 6 drives the safety lock claw 4 to rotate to a horizontal position, and the safety lock claw 4 releases the restriction on the output shaft of the lock claw cylinder. The output shaft of the locking cylinder 2 moves horizontally and abuts against the lower surface of the safety lock claw 4, so that the safety lock claw 4 cannot rotate, thereby restricting the falling of the limit beam 6 and achieving the function of locking the garbage container. At this time, the proximity switch 3 and the travel switch 5 on the output shaft of the lock claw cylinder jointly trigger a signal, so that the audible and visual alarm emits a voice signal of "container locked".
[0020] Furthermore, as a preferred embodiment, a convex portion 7 is provided on the upper surface of each longitudinal beam 12, and a limit through groove 8 is provided on the end surface of each convex portion 7. The limit beam 6 is operably clamped in the limit through groove 8. Further, the limit beam 6 is clamped and restricted through the limit through groove 8 on the convex portion 7, protecting the travel switch 5 and at the same time improving the limiting effect on the limit beam 6.
[0021] Further, as a preferred embodiment, the limiting beam 6 includes a limiting vertical plate 9 and a limiting horizontal plate 10. The lower end of the limiting vertical plate 9 is installed at one end of the limiting horizontal plate 10. The limiting vertical plate 9 and the limiting horizontal plate 10 are jointly arranged in an "L" shape. The hook groove 11 can operably lock the limiting horizontal plate 10. The length of the limiting horizontal plate 10 in the horizontal direction is equal to the depth of the limiting through groove 8. The other end of the limiting horizontal plate 10 can operably abut against the inside of the limiting through groove 8. Further, during actual use, when the trash container drives the limiting beam 6 to move in the direction close to the safety locking claw 4, the other end of the limiting horizontal plate 10 first abuts against one side wall of the hook groove 11 close to the travel switch 5, and then drives the safety locking claw 4 to rotate until the limiting horizontal plate 10 drives the safety locking claw 4 to rotate to a horizontal state. At this time, the limiting horizontal plate 10 is completely located in the hook groove 11, and the other end of the limiting horizontal plate 10 abuts against the inner wall of the limiting through groove 8, completing the limitation of the limiting beam 6. Furthermore, the safety locking claw 4 is rotatably installed on the other side of a longitudinal beam 12 through a rotating shaft. The rotating shaft and the installation of the safety locking claw 4 through the rotation of the rotating shaft are all conventional technical means in the art and will not be specifically described here.
[0022] Further, as a preferred embodiment, one side wall of the hook groove 11 is arranged flush with the side wall of the limiting through groove 8. Further, one side wall of the hook groove 11 is arranged flush with the side wall of the limiting through groove 8 to limit the other end of the limiting horizontal plate 10, so that the safety locking claw 4 stops rotating when it rotates to a horizontal state, ensuring the safety of the travel switch 5 and also ensuring the limiting effect on the limiting beam 6.
[0023] Further, as a preferred embodiment, the cross-section of the safety locking claw 4 in the vertical direction is arranged in a "U" shape to form the hook groove 11.
[0024] Further, as a preferred embodiment, the outer edge of the upper surface of the safety locking claw 4 is arranged in an arc shape. Further, the outer edge of the upper surface of the safety locking claw 4 is arranged in an arc shape to play a guiding role and facilitate the limiting horizontal plate 10 to enter the hook groove 11.
[0025] Further, as a preferred embodiment, one end of the safety locking claw 4 has a vertical surface, and the vertical surface can operably contact the detection end of the travel switch 5. Further, one end of the safety locking claw 4 has a vertical surface to make the contact between the safety locking claw 4 and the travel switch 5 more sufficient, ensuring that the safety locking claw 4 rotates in place, and thus ensuring the limiting effect on the limiting beam 6.
[0026] The above are only preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
