Abstract
Description
Technical Field
[0001] The present disclosure belongs to the technical field of switch devices, and in particular relates to a clutch for switching a switch device between electric operation and manual operation. Background Art
[0002] In an electrical switch cabinet, in order to ensure safety, the grounding switch needs to be opened and closed during maintenance. This process can be achieved through manual operation, but sometimes it needs to be converted to electric operation in application.
[0003] The clutch scheme currently used to convert the electric operation of the grounding switch to manual operation requires reverse unlocking, otherwise the electric grounding switch module will be damaged. However, the reverse unlocking process is very cumbersome, time-consuming and labor-intensive. The defects of the existing clutch scheme are that it is difficult to separate and there is a risk of getting stuck. With the trend of vigorous development of intelligent medium and high voltage switch products, the defects of the existing clutch scheme will be further magnified. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a clutch for converting a switch device between electric operation and manual operation. The clutch of the utility model overcomes the defects of the existing clutch schemes and can easily achieve the closing and separation of the clutch and the drive gear through axial force, thereby simply and effectively realizing the conversion between electric operation and manual operation.
[0005] The purpose of this disclosure can be achieved through the following technical solutions:
[0006] A clutch for converting a switchgear between electrical and manual operation, comprising:
[0007] A hexagonal main shaft, on which a first mounting plate and a second mounting plate are rotatably connected;
[0008] A clutch, wherein the clutch is slidably connected to the hexagonal spindle between the first mounting plate and the second mounting plate, a plurality of latches evenly distributed along the circumferential direction are fixedly connected to the side surface on the same side of the clutch and the second mounting plate, a circular ring is rotatably connected to the circumferential side of the clutch, a connecting rod is fixedly connected to the upper and lower ends of the circular ring, the other end of the connecting rod passes through the second mounting plate and is sleeved with a spring, and the connecting rod is slidably connected to the second mounting plate;
[0009] The driving gear is located between the clutch and the second mounting plate. A socket corresponding to the latch is circumferentially provided on the driving gear. The driving gear is rotatably connected to the sleeve. The sleeve is sleeved on the hexagonal main shaft. The sleeve is fixedly connected to the second mounting plate.
[0010] The above technical solution, its principle and technical effect:
[0011] In the natural state, the elastic force of the spring causes the connecting rod to move toward the second mounting plate, driving the ring and the clutch to move toward the drive gear until the pin is inserted into the socket. When the driving source drives the drive gear to rotate, it drives the clutch to rotate, and then drives the hexagonal spindle to rotate, realizing electric operation. When the connecting rod is pushed to move in the opposite direction, the spring is compressed and contracted, and the connecting rod drives the clutch away from the drive gear, causing the pin to disengage from the socket. At this time, the hexagonal spindle can be rotated manually to realize manual operation.
[0012] Furthermore, two shaft sleeves are sleeved on the hexagonal main shaft, and the shaft sleeves are rotatably connected to the corresponding first mounting plate and second mounting plate respectively.
[0013] Furthermore, the driving gear is meshedly connected with a transmission gear, the transmission gear is fixedly connected to an output end of the motor, and the motor is fixedly connected to the second mounting plate.
[0014] Furthermore, a retaining ring is fixedly connected to the other end of the connecting rod, and a spring is sleeved between the second mounting plate and the retaining ring.
[0015] Furthermore, a handle is slidably connected to the hexagonal main shaft on the outer side of the retaining ring.
[0016] Furthermore, a baffle is fixedly connected to one end of the hexagonal main shaft close to the handle.
[0017] Furthermore, a bolt is threadedly connected to the lower end of the baffle, and the bolt faces the handle.
[0018] Furthermore, the inner diameter of the sleeve is greater than the maximum circumferential diameter of the hexagonal spindle.
[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:
[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.
[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.
[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).
[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).
[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.
[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.
[0026] Beneficial effects of the present disclosure:
[0027] The clutch of the utility model overcomes the defects of the existing clutch scheme, and can easily realize the closing and separation of the clutch member and the driving gear through the axial force, thereby realizing the conversion between electric operation and manual operation simply and effectively.

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0033] In the description of the present disclosure, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present disclosure.
[0034] According to the concept of this application, Figures 1 to 3The following describes an embodiment of a clutch for switching a switch device between electric operation and manual operation. Specifically, the clutch is constructed as a split structure, which has components such as a hexagonal main shaft 1, a clutch 4, and a drive gear 9. Through the mutual cooperation of the provided structures such as the latch 5, the connecting rod 7, and the socket 10, in a natural state, the elastic force of the spring 8 causes the connecting rod 7 to move toward the second mounting plate 3, driving the ring 6 and the clutch 4 to move toward the drive gear 9 until the latch 5 is inserted into the socket 10. When the driving source drives the drive gear 9 to rotate, the clutch 4 is driven to rotate, and then the hexagonal main shaft 1 is driven to rotate, thereby realizing electric operation. When the connecting rod 7 is pushed to move in the opposite direction, the spring 8 is compressed and contracted, and the connecting rod 7 drives the clutch 4 away from the drive gear 9, so that the latch 5 is disengaged from the socket 10. At this time, the hexagonal main shaft 1 can be rotated manually to realize manual operation.
[0035] like Figure 1-3 As shown, a clutch for switching a switch device between electric operation and manual operation comprises:
[0036] A hexagonal spindle 1, to which a first mounting plate 2 and a second mounting plate 3 are rotatably connected;
[0037] A clutch 4 is slidably connected to the hexagonal main shaft 1 between the first mounting plate 2 and the second mounting plate 3. The side surface of the clutch 4 on the same side as the second mounting plate 3 is fixedly connected with a plurality of latches 5 evenly distributed along the circumferential direction. A circular ring 6 is rotatably connected to the circumferential side of the clutch 4. The upper and lower ends of the circular ring 6 are fixedly connected with a connecting rod 7. The other end of the connecting rod 7 passes through the second mounting plate 3 and is sleeved with a spring 8. The connecting rod 7 is slidably connected to the second mounting plate 3.
[0038] The driving gear 9 is located between the clutch 4 and the second mounting plate 3. A socket 10 corresponding to the latch 5 is circumferentially provided on the driving gear 9. The driving gear 9 is rotatably connected to a sleeve 11. The sleeve 11 is sleeved on the hexagonal main shaft 1. The sleeve 11 is fixedly connected to the second mounting plate 3.
[0039] When in use, in a natural state, the elastic force of the spring 8 causes the connecting rod 7 to move toward the second mounting plate 3, driving the ring 6 and the clutch 4 to move toward the driving gear 9 until the latch 5 is inserted into the socket 10. When the driving source drives the driving gear 9 to rotate, the clutch 4 is driven to rotate, and then the hexagonal main shaft 1 is driven to rotate, thereby realizing electric operation. When the connecting rod 7 is pushed to move in the opposite direction, the spring 8 is compressed and contracted, and the connecting rod 7 drives the clutch 4 away from the driving gear 9, so that the latch 5 is disengaged from the socket 10. At this time, the hexagonal main shaft 1 can be rotated manually to realize manual operation.
[0040] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. It is also called "spring". It is generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc.
[0041] Gears are mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the stability of gear operation has received attention.
[0042] In one embodiment of the present invention, two sleeves 12 are sleeved on the hexagonal spindle 1, and the sleeves 12 are rotatably connected to the corresponding first mounting plate 2 and second mounting plate 3. When the hexagonal spindle 1 rotates, the first mounting plate 2 and the second mounting plate 3 will not rotate accordingly.
[0043] In one embodiment of the present invention, the driving gear 9 is meshedly connected with the transmission gear 13, the transmission gear 13 is fixedly connected to the output end of the motor 14, and the motor 14 is fixedly connected to the second mounting plate 3. The motor 14 drives the transmission gear 13 to drive the driving gear 9 to achieve electric operation.
[0044] In one embodiment of the present invention, the other end of the connecting rod 7 is fixedly connected with a retaining ring 15, and the spring 8 is sleeved between the second mounting plate 3 and the retaining ring 15 to prevent the spring 8 from being separated.
[0045] In one embodiment of the utility model, a handle 16 is slidably connected to the hexagonal spindle 1 on the outer side of the retaining ring 15. It is used to manually rotate the hexagonal spindle 1. When manual operation is required, the handle 16 is pushed to press the retaining ring 15, so that the connecting rod 7 moves, the clutch 4 is separated from the driving gear 9, and the handle 16 is turned to realize manual operation.
[0046] In one embodiment of the present invention, a baffle 17 is fixedly connected to one end of the hexagonal spindle 1 close to the handle 16 to prevent the handle 16 from falling off.
[0047] In one embodiment of the present invention, the lower end of the baffle 17 is threadedly connected with a bolt 18, and the bolt 18 faces the handle 16. When the connecting rod 7 drives the clutch 4 away from the driving gear 9, the latch 5 is disengaged from the socket 10, and the adjustment bolt 18 is against the handle 16 to maintain the manual operation mode.
[0048] In one embodiment of the present invention, the inner diameter of the sleeve 11 is larger than the maximum circumferential diameter of the hexagonal spindle 1, so as to ensure that the hexagonal spindle 1 is not interfered.
