[0038] To make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of this application.

[0039] This application provides a safety locking and emergency separation device for equipment locking and emergency separation, which is applicable to reliable locking and emergency separation of equipment.

[0040] As Figure 1 and Figure 2 shown, the safety locking and emergency separation device provided by this application includes a mounting base 1, a limit rod, a locking rod, a fixing pin, a handle 5, a link 6, a compression spring 7, a blocking piece 8 and a connecting ring 9.

[0041] In this embodiment of this application, the body of the mounting base 1 is a rectangular structure, and a through hole 11 extending vertically is provided on the upper surface of the mounting base 1. In some embodiments of this application, the through hole 11 is a rectangular hole. The side surface of the mounting base 1 is fixedly connected to the fixed surface, and this side surface can be the rear surface of the mounting base 1 or the left and right side surfaces of the mounting base 1.

[0042] The blocking piece 8 is fixed at the center of the upper end of the through hole 11 of the mounting base 1, and the upper surface of the blocking piece 8 is flush with the upper surface of the mounting base 1. A circular hole for the link 6 to pass through is provided in the middle of the blocking piece 8. In some embodiments of this application, the blocking piece 8 can be a rectangular structure or a disc structure. In the preferred embodiment of this application, the blocking piece 8 does not completely cover the through hole 11 of the mounting base 1, and there is a certain distance between it and the edge of the through hole 11 of the mounting base 1, and this distance allows the limit rod and the locking rod to move.

[0043] The lower end of the link 6 passes through the circular hole of the blocking piece 8 and is hinged to the limit rod, and the upper end of the link 6 is higher than the upper surface of the mounting base 1 by a certain distance. In some embodiments of this application, the link 6 is a round rod structure.

[0044] The handle 5 is fixedly connected to the upper end of the link 6. In some embodiments of this application, the handle 5 is a disc-shaped structure.

[0045] The compression spring 7 is sleeved on the link 6 and is located between the handle 5 and the blocking piece 8, and is used to provide an upward elastic force for the link 6.

[0046] The limiting rod includes a left limiting rod 21 and a right limiting rod 22, and the left limiting rod 21 and the right limiting rod 22 have the same structure. In some embodiments of the present application, both the left limiting rod 21 and the right limiting rod 22 can be of a rectangular long bar structure or a round bar structure. The left limiting rod 21 and the right limiting rod 22 are hinged to the lower end of the connecting rod 6, the other end of the left limiting rod 21 is hinged to the upper end of the left locking rod 31, the other end of the right limiting rod 22 is hinged to the upper end of the right locking rod 32. The left limiting rod 21 and the right limiting rod 22 are on the same horizontal line, and the left limiting rod 21 and the right limiting rod 22 are respectively in contact with the surface of the plug 8.

[0047] The locking rod includes a left locking rod 31 and a right locking rod 32, and the left locking rod 31 and the right locking rod 32 have the same structure. The fixing pins include a left fixing pin 41 and a right fixing pin 42. In some embodiments of the present application, both the left locking rod 31 and the right locking rod 32 can be of a rectangular long bar structure or a round bar structure. Both the left locking rod 31 and the right locking rod 32 are arranged in the through hole 12 of the mounting seat 1. The upper end of the left locking rod 31 is hinged to the left limiting rod 21, and about the middle position of the left locking rod 31 is hinged to the mounting seat 1 through the left fixing pin 41, thereby restricting the left locking rod 31 in the through hole 12 of the mounting seat 1, and the left locking rod 31 can rotate around the left fixing pin 41. The upper end of the right locking rod 32 is hinged to the right limiting rod 22, and about the middle position of the right locking rod 32 is hinged to the mounting seat 1 through the right fixing pin 42, thereby restricting the right locking rod 32 in the through hole 12 of the mounting seat 1, and the right locking rod 32 can rotate around the right fixing pin 42.

[0048] Among them, the left fixing pin 41 and the right fixing pin 42 are located at a position close to the lower side edge of the through hole 12 on the mounting seat 1, and can make the lower end of the left locking rod 31 contact the lower end of the right locking rod 32, thereby forming a closed area between the lower edge of the mounting seat 1, the left locking rod 31 and the right locking rod 32.

[0049] The connecting ring 9 is of a ring structure, which can be a circular ring or a polygonal ring. The lower end of the connecting ring 9 is connected to the device 20, and the upper end of the connecting ring 9 can be sleeved in the closed area formed by the lower edge of the mounting seat 1, the left locking rod 31 and the right locking rod 32.

[0050] When using this device to lock the equipment, as long as the handle 5 is pressed downward for a certain stroke, the connecting rod 6 drives the left and right limiting rods to move, destroying the dead point effect formed by the left and right limiting rods. The left and right limiting rods cause the lower parts of the left and right locking rods to open outward simultaneously. The connecting ring 9 abuts upward against the lower surface of the mounting seat 1 located between the left and right locking rods. Then the handle 5 is released, and the connecting rod 6 moves upward under the action of the compression spring 6. The connecting rod 6 drives the left and right limiting rods to make the lower ends of the left and right locking rods rotate inward and close simultaneously, locking the connecting ring 9 in the closed area between the lower surface of the mounting seat 1 and the left and right locking rods, thereby achieving the rapid locking effect of the equipment 20.

[0051] When unlocking is required, simply press the handle 5 downward by a certain stroke. The connecting rod 6 drives the left and right limit rods to move. The left and right limit rods cause the lower ends of the left and right locking rods to open outward simultaneously. At this time, the connection ring 9 is no longer restricted. The connection ring 9 disengages from the closed area between the lower surface of the mounting seat 1 and the left and right locking rods, thus realizing the emergency quick separation function of the device 20.

[0052] Under the action of the compression spring, the left and right limit rods of the device of the present application are always on the same horizontal line. Thus, the left and right limit rods form a dead point effect, preventing the lower ends of the left and right locking rods from rotating and opening outward, ensuring the reliable locking ability of the device 20 in an external vibration environment, and improving the reliability and safety of use.

[0053] The present application integrates the locking and emergency separation of the device in a simple device, reduces costs, has high reliability, realizes the reliable locking and emergency separation of the device, and the device is simple, firm, easy to use, and not restricted by external conditions.

[0054] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
