Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and particularly to a circuit breaker mechanism that is convenient to use. Background Art

[0002] A circuit breaker refers to a switching device that can close, carry, and interrupt the current under normal circuit conditions and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their usage scope. The boundary between high and low voltages is relatively blurred, and generally, those above 3 kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power supply lines and motors, etc. When they encounter serious overload, short circuit, undervoltage, and other faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over- and under-thermal relay, etc. Moreover, generally, no components need to be changed after breaking the fault current; it has been widely used. Chinese patent application with publication number CN119542086A discloses a circuit breaker operating mechanism and its circuit breaker. The operating mechanism includes a handle, a moving contact piece, a locking piece, a locking spring, and a contact spring. Initially, the limiting surface of the moving contact piece contacts the limiting block on the housing, making the operating mechanism in the open state; the operating handle pushes the U-shaped rod, and one end of the U-shaped rod contacts the first rod contact surface of the moving contact piece and the second rod contact surface of the locking piece at the same time. Under the push of the U-shaped rod, the moving contact piece rotates clockwise around the opening and closing rotating shaft until the moving contact of the moving contact piece contacts the static contact on the housing, making the operating mechanism in the closed state. The operating mechanism of the present invention has the advantages of simple structure, low cost, and fast opening speed.

Due to the small structural design of the handle and the inconvenient position setting for operation, there are problems such as inconvenient operation and the need to apply a relatively large force when operating the handle, making the entire operation process extremely inconvenient; at the same time, since there is no structure for reducing the impact force, the handle will impact the through-hole wall when swinging, which will cause damage to the handle.

Detailed implementation manners

[0017] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present invention pertains. The words such as "including" used herein mean that the elements or objects appearing before this word cover the elements or objects enumerated after this word and their equivalents, without excluding other elements or objects.

[0018] In view of the problems existing in the prior art, an embodiment of the present invention provides a circuit breaker mechanism that is convenient to use, as Figure 1 and Figure 2 shown. The circuit breaker mechanism that is convenient to use includes: a swing hole 2 is provided on the housing of the circuit breaker body 1; a handle 3 is movably arranged in the swing hole 2. During actual operation, after the handle 3 trips, it will deflect towards the right side wall of the swing hole 2, and when the handle 3 returns to the original position, the handle 3 deflects towards the left side wall of the swing hole 2; a pushing mechanism 4 is sleeved outside the handle 3, and the pushing mechanism 4 is used to push the handle 3. Specifically, as the pushing mechanism 4 moves left or right, it will drive the handle 3 to deflect left or right. In one example, when the circuit is overloaded and the device trips, the handle 3 deflects to the right; a buffer mechanism 5 is sleeved outside the pushing mechanism 4, and the buffer mechanism 5 is used to buffer the movement of the handle 3, thereby reducing the damage to the handle 3 caused by the impact force; a driving component 6 is arranged outside the circuit breaker body 1, and the driving component 6 is used to drive the handle 3 to quickly return to the initial position after tripping. Specifically, the cooperation between the driving component 6 and the pushing mechanism 4 can realize the deflection control of the handle 3 left or right.

[0019] The present invention improves the existing circuit breaker structure. The improved circuit breaker is provided with a combined mechanism of a pushing mechanism 4 and a driving component 6 outside the handle. The setting of this combined structure can conveniently operate the handle 3, thereby achieving the effect of saving time and effort; the setting of the buffer mechanism 5 can reduce the impact force when the handle 3 contacts the wall of the swing hole 2, thereby playing a role in protecting the handle 3.

[0020] In one embodiment, as Figure 3 shown, the pushing mechanism 4 includes: The first push plate assembly 41 and the second push plate assembly 42 are respectively arranged on opposite sides of the handle 3. It can be understood that the first push plate assembly 41 and the second push plate assembly 42 are respectively arranged on the left and right sides of the handle 3. In this way, when the handle 3 needs to be deflected and adjusted, the handle 3 can be pushed to deflect to the right by the first push plate assembly 41, and the handle 3 can be pushed to deflect to the left by the second push plate assembly 42.

[0021] The connecting assembly 43 is arranged between the first push plate assembly 41 and the second push plate assembly 42 for connecting the first push plate assembly 41 and the second push plate assembly 42. Among them, the connecting assembly 43, the first push plate assembly 41 and the second push plate assembly 42 form a first activity cavity 44 for the handle 3 to be movably arranged.

[0022] In one embodiment, as Figure 5 shown, the first push plate assembly 41 includes: An installation groove 412 is formed on the side of the push plate body 411 facing the handle 3; a roller shaft assembly (not labeled) is rotatably arranged in the installation groove 412, and the roller shaft assembly contacts the handle 3, and the roller shaft assembly makes the handle 3 and the push plate body 411 in rolling connection. In this embodiment, the structure of the first push plate assembly 41 is further optimized. When the optimized first push plate assembly 41 contacts the handle 3, it can be transformed from frictional contact to rolling contact, so as to reduce the frictional force between the push plate body 411 and the handle 3.

[0023] In one embodiment, as Figure 4 、 Figure 5 and Figure 6 shown, the roller shaft assembly includes: One end (which can be understood as the left end) of the outer roller shaft 413 extends out of the installation groove 412; the inner roller shaft 414 is fixedly inserted into the outer roller shaft 413; the first rotating rod 415 is fixedly inserted into the inner roller shaft 414, and the first rotating rod 415 is rotatably arranged on the installation groove 412. It should be noted that the outer roller shaft 413 in this embodiment is made of an elastic material, so that while driving the handle 3 to swing, the impact force between the handle 3 and the push plate body 411 can also be reduced, thereby reducing the damage to the handle 3.

[0024] In different applicable environments, the thickness of the handle 3 is inconsistent. In order to enable the pushing mechanism 4 to be applicable to different environments, the present invention further optimizes the structure of the connecting component 43. The optimized connecting component 43 can achieve length adjustment. In this way, through the length adjustment, the distance between the first pushing plate component 41 and the second pushing plate component 42 can be changed, so that the pushing mechanism 4 is applicable to handles 3 of different thicknesses, and further the applicable range of the device is wider.

[0025] Specifically, in one embodiment, as Figure 7 and Figure 8 shown, the connecting component 43 includes a first L-shaped plate 431 and a second L-shaped plate 432 respectively fixedly connected to the first pushing plate component 41 and the second pushing plate component 42, and the first L-shaped plate 431 and the second L-shaped plate 432 are arranged in central symmetry; a first straight rack 433 is fixedly connected to the first L-shaped plate 431, the first straight rack 433 meshes with a first gear 434, the first gear 434 is fixedly sleeved outside the threaded rod 435, the threaded rod 435 is threadedly inserted into the threaded hole 436, and the threaded hole 436 is opened on the second L-shaped plate 432. In this embodiment, the structure design of the connecting component 43 is reasonable, which can not only achieve length adjustment, but also realize length adjustment under the action of its own structure.

[0026] During operation, the threaded rod 435 is rotated. The rotation of the threaded rod 435 will drive the first gear 434 to rotate. The rotation of the first gear 434 will drive the first straight rack 433 to move left or right. The left or right movement of the first straight rack 433 will drive the first pushing plate component 41 to move left or right relative to the second pushing plate component 42 through the first L-shaped plate 431. Through the adjustment function, the distance between the first pushing plate component 41 and the second pushing plate component 42 can be adjusted, so that the pushing mechanism 4 can be applicable to different ranges. It should be noted that the structure design of the connecting component 43 is simple and reasonable, and the operation can achieve the effect of convenient operation.

[0027] In order to make the movement of the first L-shaped plate 431 towards the second L-shaped plate 432 play a role of guiding and limiting, so that the first L-shaped plate 431 only moves in the horizontal direction. In one embodiment, as Figure 8As shown, the connection component 43 further includes a first guiding and telescopic component 437. The first guiding and telescopic component 437 includes: a first guiding telescopic rod 4371 fixedly arranged on the first L-shaped plate 431; a first guiding telescopic cylinder 4372 fixedly arranged on the second L-shaped plate 432, and the first guiding telescopic cylinder 4372 is movably sleeved outside the first guiding telescopic rod 4371; a first guiding telescopic spring 4373 wound outside the first guiding telescopic rod 4371, and two ends of the first guiding telescopic spring 4373 are respectively fixedly connected to the side wall of the first guiding telescopic rod 4371 and the outer side wall of the first guiding telescopic cylinder 4372.

[0028] In this embodiment, the setting of the first guiding and telescopic component 437 can not only play a guiding and supporting role in the movement of the first L-shaped plate 431, enabling the first L-shaped plate 431 to move only in the horizontal direction, but also provide a restoring force for the restoring process of the first L-shaped plate 431.

[0029] In one embodiment, as Figure 3 shown, the buffer mechanism 5 includes: a U-shaped support plate 51 fixedly arranged on the outer side wall of the circuit breaker body 1, and a second moving cavity 52 for the movement of the pushing mechanism 4 is formed on the U-shaped support plate 51; one end of a second guiding and telescopic component 53 is fixedly connected to the inner side wall of the U-shaped support plate 51, and the other end is fixedly connected to the pushing mechanism 4. The second guiding and telescopic component 53 is used to buffer the movement of the handle 3.

[0030] During operation, when the pushing mechanism 4 moves left or right, on the one hand, it will drive the movement of the handle 3, and on the other hand, it will cause the second guiding and telescopic component 53 to be stretched or compressed. During the stretching and compression processes, both will buffer the movement process of the first pushing plate component 41, thereby reducing the impact force between the devices and further protecting the devices.

[0031] It should be noted that, in the Figure 3 example, only one second guiding and telescopic component 53 is provided in the buffer mechanism 5. Of course, it is not limited to only one, and two or more can also be provided. For example, in one example, when the number of the second guiding and telescopic components 53 is set to two, the two second guiding and telescopic components 53 are respectively arranged on the left and right sides of the pushing mechanism 4.

[0032] In one embodiment, as Figure 3 shown, the second guiding and telescopic component 53 includes: The second guiding telescopic rod 531 is fixedly arranged on the pushing mechanism 4; the second guiding telescopic cylinder 532 is fixedly arranged on the inner side wall of the U-shaped support plate 51; the second guiding telescopic spring 533 is wound around the second guiding telescopic rod 531, and two ends of the second guiding telescopic spring 533 are respectively fixedly connected to the side wall of the second guiding telescopic rod 531 and the outer side wall of the second guiding telescopic cylinder 532.

[0033] Specifically, during the compression or stretching process of the second guiding telescopic assembly 53, the second guiding telescopic rod 531 moves into or out of the second guiding telescopic cylinder 532. During this movement, the second guiding telescopic spring 533 is compressed or stretched. In this way, during the compression or stretching process, through the elastic force of the second guiding telescopic spring 533 itself, a buffering effect can be achieved to reduce the impact force.

[0034] In one embodiment, as Figure 3 and Figure 4 shown, the driving assembly 6 includes: a moving through hole 61 is opened on the U-shaped support plate 51; a connecting slider 62 is movably arranged in the moving through hole 61. One end (which can be understood as the rear end) of the connecting slider 62 is fixedly connected to the connecting component 43, and the other end (which can be understood as the front end) is fixedly connected with a fixed seat 63; a second straight rack 64 is fixedly arranged on the fixed seat 63; a second gear 65 meshes with the second straight rack 64; a second rotating rod 66 is fixedly inserted on the second gear 65, and the second rotating rod 66 is rotatably arranged on the outer top wall of the circuit breaker body 1. A connecting groove 67 is opened at the upper end of the second rotating rod 66; an extended turning handle 68 is movably inserted in the connecting groove 67.

[0035] In this embodiment, the structural design of the driving assembly 6 is simple and reasonable. On the one hand, by turning, the pushing mechanism 4 can be used to push the handle 3 to swing, and convenient operation and time-saving and labor-saving effects can be achieved during the pushing process. On the other hand, the extended turning handle 68 in the driving assembly 6 can be disassembled or replaced with different sizes to be applicable to different application scenarios; moreover, by replacing it with an extended turning handle 68 with a longer length, the operator can be prevented from being closer to the power source, thus achieving a safer effect.

[0036] In one embodiment, the connecting groove 67 is arranged to match the extended turning handle 68, and the cavity of the connecting groove 67 is in a rectangular structure or a cross-shaped structure.

[0037] Although the embodiments of the present invention have been described in detail above, it will be obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are all within the scope and spirit of the present invention. Moreover, the present invention described herein can have other embodiments and can be implemented or realized in various ways.
