Description

Technical Field

[0001] The invention relates to the field of electric control cabinets, and in particular to a five-protection padlock device. Background Art

[0002] As a core device in a complete set of switchgear, the vacuum circuit breaker can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the action of the relay protection device when the system fails. It has a fairly complete arc extinguishing structure and sufficient current-breaking capacity. In the normal operation of the power supply system, in order to prevent the circuit breaker from being operated incorrectly and the circuit breaker from being shaken in or out, adding a "five-protection" padlock to the trolley operating hole has become the only choice. At present, the existing "five-protection" padlock device usually includes a component that can move and block the trolley operating hole, and then the padlock can ensure that the component stably blocks the trolley operating hole; however, the structure of the corresponding component and its movement method are relatively cumbersome, inconvenient to install, and the component is not convenient enough to block and open the trolley operating hole. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] The technical problem to be solved by the present invention is to provide a five-protection padlock device, which has a simple structure, is easy to install, can effectively prevent misoperation of the circuit breaker, ensure safe and reliable power supply, and is relatively convenient for blocking and opening the operating hole of the opponent vehicle.

[0005] 2. Technical solution

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0007] A five-proof padlock device, comprising a bottom plate with a trolley operation hole, two pads, a first lock plate and a second lock plate, wherein the bottom plate is in a rectangular flat plate shape, a first mounting hole is formed at each of the four corners of the bottom plate, and the trolley operation hole is formed at the center of the bottom plate; the pad is in a strip plate shape, two second mounting holes are formed on the pad, and the distance between the two second mounting holes is equal to the distance between the two first mounting holes in the length direction of the bottom plate, the two pads are respectively mounted on the two edges of the bottom plate in the corresponding length direction, and the facing sides of the two pads and the space between the two pads are The bottom plate portion of the lock plate forms a slide groove; the lock plate 1 is slidably connected in the slide groove, and the sliding direction of the lock plate 1 is parallel to the length direction of the bottom plate; a third mounting hole is provided at each of the four corners of the lock plate 2, and the four third mounting holes can coincide with the four first mounting holes at the same time; an adapter hole identical to the trolley operation hole is provided at the center of the lock plate 2; a first convex plate passing through the adapter hole is vertically fixed on one side of the front face of the lock plate 1, a second convex plate facing the first convex plate is vertically fixed on one side of the adapter hole, and a padlock hole and a lead seal hole are correspondingly provided on the first convex plate and the second convex plate;

[0008] Two groups of clamping assemblies arranged opposite to each other in the width direction are fixed on the lock plate 2 on the side where the second convex plate is located. The clamping assembly includes a fixed block fixed on the lock plate 2, a moving block connected to the fixed block through a spring 1, and a limit rod fixed on the moving block. The limit rods of the two groups of clamping assemblies are located on the adjacent sides of the two groups of clamping assemblies. A socket facing the middle part between the two groups of clamping assemblies is opened on the second convex plate. A plug-in plate facing the plug-in plate and capable of being inserted into the plug-in plate is fixed on the first convex plate. The plug-in plate corresponds to the two groups of clamping assemblies. Slots are provided on both sides of the plug plate, and when the part of the plug plate corresponding to the slot is located between the two groups of clamping assemblies and the spring one is in a natural state, the opposite ends of the two limit rods are inserted into the slots on the corresponding sides; a connecting plate connected to the two pads is provided on the side where the clamping assembly is located between the lock plate two and the bottom plate, and spring two is connected at both ends between the connecting plate and the opposite sides of the lock plate one, and when the spring two is in a natural state, the lock plate one is located on the side away from the connecting plate, and the first convex plate is located on the side of the adapter hole facing away from the second convex plate.

[0009] Furthermore, one end of the pad is flush with one end of the bottom plate, and the length of the pad is greater than that of the bottom plate. The two pads are provided with sliding openings extending along the length direction of the pads on the facing sides, and the corresponding two sides of the lock plate 1 are respectively located in the sliding openings on the corresponding sides. The provision of the sliding openings can facilitate the sliding movement of the lock plate 1 along the pad and can limit the lock plate 1.

[0010] Furthermore, the bottom plate, the backing plate and the second lock plate are arranged longitudinally in the length direction. This arrangement can utilize the gravity of the first lock plate, and after the padlock and the plug plate are opened, the first lock plate can be moved away from the second lock plate more quickly.

[0011] Furthermore, a strip plate extending toward a side facing away from the second convex plate is fixed on the moving block. The provision of the strip plate can provide convenience for manually moving the moving block.

[0012] Furthermore, a telescopic sleeve is connected between the fixed block and the movable block and is sleeved on the outside of the spring 1. The telescopic sleeve can limit the spring 1 to prevent the spring 1 from bending, ensure the linear movement of the movable block, and effectively prevent the limit rod from accidentally leaving the slot.

[0013] Furthermore, a hollow rod is fixed to the first mounting hole and passes through the second mounting hole and the third mounting hole in sequence, and a cavity is provided in the hollow rod and passes through the upper and lower end surfaces thereof. The hollow rod can string the bottom plate, the pad plate and the lock plate together, and then the device can be installed on the cabinet door through the cavity in the hollow rod, and the bottom plate, the pad plate and the lock plate are not easily misaligned, and the installation operation is relatively convenient.

[0014] 3. Beneficial effects

[0015] (1) The present invention comprises a base plate with a trolley operating hole, two pads, a lock plate 1, a lock plate 2 and a connecting plate. During installation, the lock plate 1 is first inserted into the sliding openings of the two pads, and then the two pads are respectively placed on the two longitudinal edges of the base plate, and the second mounting holes of the pads are sleeved on the corresponding hollow rods. Then, the connecting plate is installed at one end of the two pads that is flush with the pads, and the connecting plate and the lock plate 1 are connected by a spring 1, and the lock plate 1 is pushed to slide in the sliding opening to confirm that the lock plate 1 can slide in the sliding opening and can drive the spring 1 to stretch or compress; then the third mounting hole of the lock plate 2 is sleeved on the corresponding hollow rod, and the first convex plate is passed through the adapter hole, and the middle parts of the plug plate, the socket and the two sets of supporting components are aligned. Finally, the device can be installed on the cabinet door with screws or rivets, which is convenient to install. The device can be installed on the inner side of the cabinet door, is not easy to be damaged, and is firm and reliable.

[0016] (2) When locking the switch, the first lock plate is moved to block the trolley operating hole, and the moving blocks of the two groups of clamping assemblies are pushed to opposite sides. At this time, the second spring is compressed, the plug plate passes through the socket, and the slot on the plug plate faces the limit rod. Then the strip is loosened, and the two moving blocks move toward each other under the resetting action of the first spring, so that the limit rod is inserted into the slot. The plug plate is locked by the limit rod and cannot fall, driving the second lock plate to be stably located there. At this time, the first convex plate and the second convex plate are close to each other, and the padlock is passed through the padlock holes on the first convex plate and the second convex plate at the same time and locked. The operation is simple, and it can effectively prevent misoperation of the circuit breaker and ensure safe and reliable power supply.

[0017] (3) When the present invention is opened, the padlock is first opened and removed, and then the moving blocks of the two sets of clamping assemblies are pushed away from each other, so that the limit rod is moved out of the slot. Under the gravity of the lock plate 1 and the reset action of the spring 2, the lock plate 1 automatically and quickly moves along the slide groove to the side away from the second convex plate until the lock plate 1 moves to the bottom of the contact slide, thereby realizing the automatic reset of the lock plate 1, simplifying the operation steps and facilitating use. At this time, the trolley operation hole is exposed, allowing the circuit breaker to be operated.

[0018] In summary, the present invention has a simple structure and is easy to install. It can effectively prevent misoperation of the circuit breaker and ensure safe and reliable power supply. In addition, the blocking and opening operations of the hand vehicle operating hole are relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS
