Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage circuit breakers, in particular to a circuit breaker opening and closing control mechanism. Background Art

[0002] Circuit breakers are mainly used for overload, undervoltage and short circuit protection of electrical equipment. In the related art, the opening and closing of circuit breakers are realized by rotating the handle, but manual control has operational limitations. If the operator cannot rush to the site in time, the circuit breaker will remain in the open state and cannot be closed in time, which may cause lag in power consumption and distribution, making it inconvenient to use. In addition, the existing circuit breaker opening and closing operating mechanism has a complex structure, is inconvenient to operate, and is not reliable. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide a circuit breaker opening and closing control mechanism which has a reasonable structural design, can achieve the purpose of manual and electric control of opening and closing, and is easy to operate and safe to use.

[0004] The utility model adopts a technical solution to solve its technical problem. A circuit breaker opening and closing control mechanism comprises a clutch shaft, a transmission gear assembly, and a drive assembly. A manual operation part is provided on the top of the clutch shaft. The transmission gear assembly comprises a first transmission gear, a second transmission gear, a third transmission gear and a gear set. The first transmission gear is fixed to the upper part of the clutch shaft. The second transmission gear is located below the first transmission gear and has a ratchet matching structure with the clutch shaft. The third transmission gear meshes with the first transmission gear for transmission. The gear set meshes with the second transmission gear for transmission. The drive assembly comprises a fixed slide, a sliding block, a connecting rod, and a drive motor. The sliding block is slidably connected to the fixed slide, and the head of the switch handle is penetrated on the sliding block. One end of the connecting rod is connected to the third transmission gear, and the other end of the connecting rod is connected to the sliding block. The gear set is driven by the drive motor.

[0005] The advantages of adopting the above technical solution are as follows: when manually opening and closing the switch, the operator uses a tool to make the manual operating part drive the clutch shaft to rotate clockwise, and the first transmission gear fixed on the clutch shaft rotates synchronously and drives the third transmission gear to rotate. Since one end of the connecting rod is fixed on the third transmission gear, and the other end of the connecting rod is fixed on the sliding block, and the sliding block is slidably matched with the fixed slide, the connecting rod will cause the sliding block to move back and forth during the rotation of the third transmission gear, thereby driving the switch handle to open and close the internal structure of the circuit breaker body. Since the second transmission gear and the clutch shaft are in a ratchet matching structure, the clutch shaft will not drive the second transmission gear to rotate during manual opening and closing. Similarly, during electric opening and closing, the gear set is rotated by the driving motor to cooperate with the gear set The second transmission gear rotates, and in this process the second transmission gear will rotate counterclockwise relative to the clutch shaft first. When the ratchet matching structure forms a locking match, the second transmission gear will drive the first transmission gear to rotate through the clutch shaft, and then drive the switch handle through the third transmission gear, the connecting rod, and the sliding block to open and close the internal structure of the circuit breaker body. Therefore, the design of the above structure can enable the circuit breaker body to achieve the purpose of manual and electric control of opening and closing, and the control action of the second transmission gear and the clutch shaft is equivalent to incomplete overlap, thereby improving operational safety and making it safer to use. The overall gear transmission matching method is adopted, and the transmission efficiency is also high.

[0007] The advantages of adopting the above technical solution are as follows: the ratchet groove is set on the inner wall surface of the shaft hole of the second transmission gear, and the clutch hole for installing the clutch ball and the spring is set on the clutch shaft. During the relative rotation of the second transmission gear and the clutch shaft, the clutch ball will always be in contact with the inner wall of the ratchet groove through the pre-tightening force of the spring. The structural design is simple, the molding position is reasonable, and the use effect is also good.

Therefore, through the structural design of the lower fixed plate and the upper fixed plate, the purpose of integrated installation of the third transmission gear, the clutch shaft with the first transmission gear and the second transmission gear, and the gear set is achieved, and the assembly method is reasonable. At the same time, compared with the prior art, by arranging screw-fixed mounting columns on the lower fixed plate and the upper fixed plate, the first convex hole block, the second convex hole block, and the third convex hole block are formed in an integrated manner, which simplifies the assembly process and assembly parts, and the use effect is also good.

[0012] Furthermore, the fixed slide comprises a first mounting block, a second mounting block, and two guide rods, two ends of the guide rods are respectively fixed on the first mounting block and the second mounting block, and the sliding block is slidably matched with the guide rods.

[0013] The advantages of adopting the above technical solution are as follows: the fixed slide after assembly will be a rectangular frame structure, and the sliding block can achieve the purpose of sliding by cooperating with the guide rod.

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the embodiments of the utility model and / or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0031] like Figure 1-Figure 9 As shown, a circuit breaker opening and closing control mechanism includes a clutch shaft 1, a transmission gear assembly, and a drive assembly.

The drive assembly includes a fixed slide, a sliding block 7, a connecting rod 8, and a plurality of gears. and a driving motor 9, the fixed slide is fixedly arranged, the sliding block 7 is slidably connected to the fixed slide, and the head of the switch handle is inserted into the sliding block 7, that is, a through hole matching the head of the switch handle will be formed on the sliding block 7, one end of the connecting rod 8 is connected to the third transmission gear 5 by a screw, and the other end of the connecting rod 8 is connected to the sliding block 7 by a screw. By coordinating the fixed slide, the sliding block 7, the connecting rod 8, and the third transmission gear 5, the end of the connecting rod 8 cooperating with the third transmission gear 5 will rotate circumferentially, and the end of the connecting rod 8 cooperating with the sliding block 7 will move linearly, and the gear set 6 is driven by the driving motor 9.

[0032] The working principle of the above structure is as follows: during manual opening and closing, the operator uses a tool to make the manual operating part 2 drive the clutch shaft 1 to rotate clockwise (the movement direction of the clutch shaft 1 relative to the second transmission gear 4), and the first transmission gear 3 fixed on the clutch shaft 1 rotates synchronously and drives the third transmission gear 5 to rotate. Since one end of the connecting rod 8 is connected to the third transmission gear 5, and the other end of the connecting rod 8 is connected to the sliding block 7, and the sliding block 7 is slidably matched with the fixed slide, the connecting rod 8 will cause the sliding block 7 to move back and forth during the rotation of the third transmission gear 5, thereby driving the switch handle to open and close the internal structure of the circuit breaker body 33. Since the second transmission gear 4 and the clutch shaft 1 are in a ratchet matching structure, the clutch shaft 1 will not drive the second transmission gear 4 to rotate during manual opening and closing. Similarly, during electric opening and closing, the gear set 6 is rotated by the driving motor 9, and the second transmission gear 4 matched with the gear set 6 rotates. In this process, the second transmission gear 4 will first rotate relative to the clutch shaft 1 Rotate clockwise (the movement direction of the second transmission gear 4 relative to the clutch shaft 1).

Therefore, the design of the above structure can enable the circuit breaker body 33 to achieve the purpose of manual and electric control of opening and closing, and the control action of the second transmission gear 4 and the clutch shaft 1 is equivalent to incomplete overlap, thereby improving operational safety and making it safer to use. The overall gear transmission matching method is adopted, and the transmission efficiency is also high.

The above structure can achieve the purpose that the second transmission gear 4 can drive the clutch shaft 1 to rotate only when it rotates clockwise (the movement direction of the clutch shaft 1 relative to the second transmission gear 4), and the clutch shaft 1 does not rotate when the second transmission gear 4 rotates counterclockwise (the movement direction of the second transmission gear 4 relative to the clutch shaft 1).
