[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] like Figure 1 As shown, the emergency manual mechanism provided by the present invention mainly consists of a direct-push cylinder 1, a mounting base 2, a spring 3, a cylinder connector 4, a manual connecting rod 5, an anti-rotation pin 6, a manual mounting base 7, a sliding pin 8, a pressure plate 9, a manual screw 10, a manual bushing 11, a sliding rod 12, a sliding rod mounting base 13, a pin 14, a connecting rod 15, a locking pin 16, a rotating pin 17, and a fastener 18.

[0027] like Figure 1 As shown, the main structure of an emergency manual mechanism is as follows: The direct-drive cylinder 1, manual mounting base 7, pressure plate 9, and sliding rod mounting base 13 are fixed to the mounting base 2 by fasteners 18.

[0028] The cylinder connector 4 and the telescopic rod of the direct-push cylinder 1 are connected together by threads. The spring 3 is fitted onto the cylinder connector 4 and the telescopic rod of the direct-push cylinder 1. The cylinder connector 4 has a flange 401 in the middle for engaging with the spring 3. One side of the flange 401 has an internally threaded section 402 for connecting with the telescopic rod of the direct-push cylinder 1, and the other side of the flange 401 has a connecting plate 403 for connecting the connecting rod 15. The connecting plate 403 has an internally threaded hole for connecting with the manual connecting rod 5. The two form a threaded connection, such as... Figure 2 As shown.

[0029] One sliding rod 12, one sliding rod mounting base 13, one pin 14, and one connecting rod 15 are symmetrically arranged left and right along the axis of the telescopic rod of the direct-push cylinder 1. The two connecting rods 15 form a rotating pair with the cylinder joint 4 through the pivot pin 17. The sliding rod 12 and the connecting rod 15 form a rotating pair through the pin 14. The sliding rod 12 and the sliding rod mounting base 13 form a sliding pair. The outer end of the sliding rod 12 is provided with an external thread for connecting with the locking and releasing component.

[0030] like Figure 3 As shown, one end of the manual connecting rod 5 is connected to the cylinder connector 4 by a thread, and the connecting part is prevented from rotating by a locking pin 16. The other end of the manual connecting rod 5 is embedded in the manual bushing 11. The manual bushing 11 is provided with an elongated hole. The sliding pin 8 passes through the elongated hole on the manual bushing 11 and is fixed to the manual connecting rod 5, so that the manual connecting rod 5 can slide left and right within the range of the elongated hole of the manual bushing 11.

[0031] The manual bushing 11 and the manual mounting base 7 form a sliding pair. The anti-rotation pin 6 is connected to the manual mounting base 7 by a thread, which restricts the rotation of the manual bushing 11 and the manual mounting base 7. The right end of the manual bushing 11 and the manual screw 10 form a threaded pair. The manual bushing 11 is provided with a limiting groove (anti-rotation groove) that cooperates with the anti-rotation pin 6 to prevent the manual bushing 11 from rotating. The limiting groove and the anti-rotation pin 6 cooperate to achieve the anti-rotation function without affecting the sliding of the manual bushing and the manual mounting base.

[0032] The mounting base 2 is provided with a screw mounting plate 19. The rear end of the manual screw 10 is connected to the screw mounting plate 19 via a pressure plate 9. The rear end of the manual screw 10 is provided with a limiting flange that mates with the pressure plate 9. The pressure plate is provided with a stepped portion for mates with the limiting flange to press the manual screw 10 tightly against the screw mounting plate 19. Figure 4 As shown.

[0033] The manual screw 10 and the mounting base 2 form a rotating pair, and the pressure plate 9 restricts the manual screw 10 and the mounting base 2 from moving left and right. like Figure 1 As shown, when an emergency manual mechanism is not in operation, the manual bushing 11 is in the initial position, the telescopic rod of the direct-push cylinder 1 extends, and the sliding rod 12 extends to both sides through the connecting rod 15. At the same time, the cylinder joint 4 drives the manual connecting rod 5 to extend to the right, and the sliding pin 8 moves to the right side of the elongated hole of the manual bushing 11, completing the automatic locking action of the mechanism. When the telescopic rod of the direct-push cylinder 1 retracts, the sliding rod 12 retracts to both sides through the connecting rod 15. At the same time, the cylinder joint 4 drives the manual connecting rod 5 to retract to the left, and the sliding pin 8 moves to the left side of the elongated hole of the manual bushing 11, completing the automatic release action of the mechanism.

[0034] like Figure 5As shown, if the direct-push cylinder 1 malfunctions or loses its power source, the mechanism cannot automatically complete the release action. In the emergency manual release state, the manual screw 10 is rotated counterclockwise from the right side of the pressure plate 9. The manual bushing 11 moves to the left under the action of the threaded pair, and drives the manual connecting rod 5 to move to the left through the sliding pin 8, causing the cylinder joint 4 to move to the left. This compresses and stores energy in the spring 3, and drives the sliding rod 12 to retract to both sides through the connecting rod 15, completing the manual release action of the mechanism. In the locked state, the manual screw 10 is rotated clockwise from the right side of the pressure plate 9. The manual bushing 11 moves to the right under the action of the threaded pair. At the same time, the cylinder joint 4 moves to the right under the action of the spring 3's unfolding force, and drives the sliding rod 12 to extend to both sides through the connecting rod 15, completing the manual locking action of the mechanism.

[0035] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
