Description

Technical Field

[0001] The utility model relates to a multifunctional protective mechanical safety interlock device, belonging to the technical field of mechanical safety interlocks. Background Art

[0002] Mechanical safety interlocks are an important part of the industrial safety field. Through a series of components such as sensors, controllers, and actuators, they monitor and control the operating state of equipment. When the equipment is in an abnormal situation, the interlock mechanism will immediately cut off the power supply or mechanical transmission to stop the operation of the equipment to ensure safety.

[0003] Chinese published patent (Publication No.: CN 217481715 U) discloses a JSL mechanical safety interlock that is easy to disassemble, including an interlock body. An interlock cooperation component for interlock fixation of external instruments is arranged on the interlock body. The interlock cooperation component includes a first support plate and a second support plate respectively arranged at both ends of a support base. A limiting rod for connecting and fixing an external instrument is inserted on the first support plate and the second support plate. A limiting ring is arranged on the limiting rod. A spring is sleeved on the limiting rod and located between the first support plate and the limiting ring. By using a screwdriver to disassemble the first bolt and the second bolt, the top plate and the two side guard plates can be disassembled respectively. The structural method is simple and easy to use. By rotating and pulling the limiting rod, the fixing column is rotated out from between the baffle plate and the first support plate, and the spring deforms and returns to a straight state, pushing the limiting rod out to connect with the connection part of the external instrument. The overall structure is simple and the use efficiency is improved;

A cavity 5 is opened inside the positioning block 2, and a locking mechanism 3 is arranged inside the cavity 5. The locking mechanism 3 includes a rotating column 301, a connecting rod 302, a connecting column 303, a plug rod 304 and a tension spring 305. The front side of the rotating column 301 penetrates to the front side of the cavity 5, and the rear side of the rotating column 301 penetrates to the inside of the cavity 5. The rear side of the rotating column 301 is fixedly connected to the front side of the connecting rod 302. The connecting rod 302 is sleeved on the surface of the connecting column 303. The rear side of the connecting column 303 is fixedly connected to the front side of the plug rod 304. The left side of the plug rod 304 is fixedly connected to the right side of the tension spring 305. The left side of the tension spring 305 is fixedly connected to the inner wall of the cavity 5. The tension spring 305 is sleeved on the surface of the plug rod 304. The left side of the plug rod 304 penetrates to the inside of the connecting block 4. A fixing groove 6 is opened on the surface of the connecting block 4. When the plug rod 304 is inserted into the fixing groove 6, they are in close contact. A limiting groove 7 is opened inside the cavity 5. A limiting rod 8 is fixedly connected to the rear side of the plug rod 304. The rear side of the limiting rod 8 penetrates to the inside of the limiting groove 7. A travel groove 9 is opened on the front side of the connecting rod 302. The inner wall of the travel groove 9 contacts the surface of the connecting column 303.

[0030] Through the locking mechanism 3, when using the positioning block 2, by rotating the rotating column 301, the plug rod 304 can be driven to move to the right, so that the positioning rod moves to the inside of the cavity 5, which is convenient for the staff to use. By setting the fixing groove 6, when the plug rod 304 is inserted and fixed with the fixing groove 6, it can be accurately inserted into the inside of the fixing groove 6 to ensure the normal use of the structure.

[0031] Embodiment 2

[0032] In one embodiment, a slot 10 is provided on the front side of the insertion rod 304, a fixing rod 11 is arranged inside the slot 10, a rotating block 12 is fixedly connected to the inner wall of the cavity 5, the inner sides of the two rotating blocks 12 are movably connected to the outer sides of the fixing rod 11, the bottom of the fixing rod 11 is movably connected to the electric telescopic rod 13 through a rotating shaft, a plug-in slot 14 is provided on the surface of the fixing plate 1, a screw 15 is arranged inside the plug-in slot 14, and twelve plug-in slots 14 and screws 15 are provided.

[0033] Through the fixing rod 11, when the locking mechanism 3 is used, the electric telescopic rod 13 can be moved upward to push the fixing rod 11 to move upward, thereby ensuring the normal use of the overall structure.
