[0043] like Figure 3 As shown, the limiting member 240 is provided with a groove 241, such as Figure 4 As shown, the rotating member 300 includes a rotating output part 310, which is located in the groove 241 to drive the limiting member 240 to move. The rotating member 300 also includes an assembly square groove 320 for rotatably connecting with the mechanical lock cylinder 400.

[0044] The specific unlocking and locking steps of the above embodiments will be described next.

[0045] When the valve needs to be locked, one end of the locking rod 210 is inserted into the locking hole 110 of the lock body 100, with the L-shaped hook part 212 of the locking rod 210 positioned above the valve handle 500. The locking rod 210 is manually pushed, at which point the spherical structure 222 of the locking pin 220 engages with the annular first locking groove 211 of the locking rod 210. Under the pushing force of the locking rod 210 and the elastic force of the elastic element 230, the locking pin 220 retracts backward. The locking rod 210 is manually pushed until the L-shaped structure of the locking rod 210 is completely locked onto the handle. Then, the locking rod 210 is moved so that the spherical structure 222 of the locking pin 220 engages with the corresponding annular first locking groove 211 on the locking rod 210. Under the elastic force of the elastic element 230, the locking pin 220 is pushed, causing it to fit tightly against the annular first locking groove 211 of the locking rod 210. At this time, the mechanical lock cylinder 400 is unlocked using the unlocking key. The mechanical lock cylinder 400 is rotated counterclockwise. The mechanical lock cylinder 400 drives the rotating part 300 to rotate through the assembly square groove 320. The rotation output part 310 drives the limiting part 240 to move, so that the limiting part 240 is locked in the second locking groove 221 of the locking pin 220. At this time, the movement of the locking pin 220 can be restricted, and the locking rod 210 is locked at the same time. The valve handle 500 is locked, and the locking is completed.

[0046] When the valve needs to be unlocked, the mechanical key is used to unlock the mechanical lock core 400, and the mechanical lock core 400 is rotated clockwise to drive the rotating part 300 to rotate through the assembly groove 320, and the rotating output part 310 drives the limiting part 240 to move, so that the limiting part 240 is separated from the second locking groove 221 of the locking pin 220, thereby reaching the unlocking position. At this time, the locking rod 210 is manually pulled to move outward, and under the pushing of the annular first locking groove 211 of the locking rod 210, the locking pin 220 is retracted into the lock body 100 under the elastic action of the elastic part 230, and the locking rod 210 is pulled out of the lock body 100, so that the valve handle 500 can be unlocked.

[0047] As shown in the drawings, Figures 5 to 8 In another embodiment of the utility model, the locking part includes a locking block 250, the locking block 250 is provided with a sliding groove 251, and the rotating part 300 has a cantilever structure 310 which can be connected with the sliding groove 251 and move along the sliding groove 251.

[0048] As shown in the drawings, Figures 6 to 7 The locking rod 210 is sequentially provided with a plurality of trapezoidal first locking grooves 211, the upper end of the trapezoidal first locking groove 211 is a slope, and the lower end is a plane, the locking block 250 has a slope structure 252 which is matched with the trapezoidal first locking groove 211, and can be matched with the slope and the plane of the trapezoidal first locking groove 211. Under the mutual matching action of the slope, the locking rod 210 is manually pushed, so that the locking rod 210 can slide into the lock body 100. When the locking rod 210 is pulled out of the lock body 100, the plane of the trapezoidal first locking groove 211 and the plane of the locking block 250 abut against each other, thereby limiting the movement of the locking rod 210, and the locking rod 210 can be locked.

[0049] As shown in the drawings, Figures 6 to 7 The locking assembly 200 further includes an elastic part 230, preferably a spring. The elastic part 230 is connected with the locking block 250, and can provide elastic restoring force for the position switching of the locking block 250. When the locking rod 210 is manually pushed or pulled, the locking block 250 moves under the elastic action of the elastic part 230, so that the locking block 250 can be tightly attached to the trapezoidal first locking groove 211 of the locking rod 210 or located outside the trapezoidal first locking groove 211.

[0050] Next, the specific unlocking steps of the above embodiment are described.

[0051] When the valve needs to be locked, one end of the locking rod 210 is inserted into the locking hole 110 of the lock body 100, and the hanging part 212 of the L-shaped structure of the locking rod 210 is located above the valve handle 500. Because the inclined surface of the locking block 250 and the inclined surface of the trapezoidal first locking groove 211 can cooperate with each other, under the cooperation of the inclined surfaces, the locking rod 210 can be manually pushed to slide into the lock body 100. Under the pushing force of the locking rod 210 and the elastic force of the elastic member 230, the locking pin 220 is retracted backward. The locking rod 210 is manually pushed until the L-shaped structure of the locking rod 210 is completely clamped on the handle. Because the plane of the trapezoidal first locking groove 211 and the plane of the locking block 250 abut against each other, the movement of the locking rod 210 is limited, the locking rod 210 can be locked, the valve handle 500 is locked, and no unlocking key is needed during the overall locking process.

[0052] When the valve needs to be unlocked, the mechanical key is used to unlock the mechanical lock cylinder 400, the mechanical lock cylinder 400 is rotated clockwise, the rotating member 300 is driven to rotate, the cantilever structure 310 cooperates with the sliding groove 251 of the locking block 250, and in the rotating process of the rotating member 300, the elastic member 230 can pull the locking block 250 to retract into the lock body 100. At this time, the locking block 250 is separated from the trapezoidal first locking groove 211 of the locking rod 210, and the locking rod 210 can be pulled out of the lock body 100, so that the valve handle 500 can be unlocked.

[0053] The utility model discloses technical scheme lock body 100 is provided with two locking hole positions 110, two locking hole positions 110 are perpendicularly staggered, and the locking rod 210 is detachably arranged in any locking hole position 110 and can slide in the lock body 100 along the preset direction, the locking rod 210 can adjust the installation position or change the direction to adapt to the limiting requirement of different types of valve handle 500 according to actual demand, and be favorable to adapt to a plurality of different types of valve handle 500. During the adjusting process, the locking member can be located in the first locking groove 211 on the locking rod 210 under the elastic action of the elastic member 230, and the locking reliability can be favorably ensured. A plurality of first locking grooves 211 are sequentially arranged on the locking rod 210, and the locking member can be located in any first locking groove 211 under the driving of the rotating member 300 to limit the sliding of the locking rod 210, or located outside any first locking groove 211 to unlock the locking rod 210. The locking and unlocking operation is quick and efficient, and the safety of the valve is improved.

[0054] The above only describes preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made under the inventive concept of the utility model, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
