Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker switch operating mechanisms, specifically a circuit breaker switch opening and closing operating mechanism that facilitates torque measurement. Background Technology

[0002] Conventional opening and closing operating mechanisms are relatively heavy and generally use an electric drive structure or an integrated electric and manual dual drive connection, which is inconvenient during installation and commissioning. In addition, since there are various structural models of circuit breaker switches, the compatibility of the operating mechanism needs to be considered. Moreover, for the purpose of easy recording, the operation of the operating mechanism can be carried out using a digital torque measuring device to obtain the force value at each stage. This requires that the initial connection state of the opening and closing operating mechanism and the connected circuit breaker switch be consistent after reset, so as to have a certain degree of adjustment capability. Utility Model Content

[0003] To address the aforementioned problem of the lack of an adjustable circuit breaker operating mechanism, this invention provides a circuit breaker switch operating mechanism that facilitates torque measurement.

[0004] The technical solution of this utility model is as follows:

[0005] A circuit breaker switch opening and closing operating mechanism for convenient torque measurement includes a support frame detachably connected to the circuit breaker switch body;

[0006] The support frame is connected to an active drive rod via a thread, and the central axis of the active drive rod is on the same straight line as the central axis of the circuit breaker switch body's opening and closing lever.

[0007] The end of the active drive rod near the opening and closing lever is rotatably connected to an adaptive regulator via a bearing, and the adaptive regulator can only move along the central axis of the active drive rod.

[0008] The adaptive regulator is connected to a connector at the end furthest from the active drive rod, and the connector is detachably connected to the opening and closing lever.

[0009] The adaptive adjuster can be adjusted at the end near the connector.

[0010] The adaptive regulator described above has the following structure: it includes a sleeve portion that is rotatably connected to the bearing and a plug portion that is connected to the connector, and the plug portion is plugged into the sleeve portion.

[0011] The detachable connection is achieved by providing an opening at the end of the insertion part away from the sleeve part.

[0012] For easy positioning and fixing, the plug-in part is elastically connected to the sleeve part, and the elastic direction is the length direction of the central axis of the active drive rod.

[0013] The aforementioned elastic connection method involves providing a spring between the insertion part and the sleeve part.

[0014] To achieve fixation at different positions, the side of the sleeve is provided with a locking member for pressing the insertion part.

[0015] To accommodate different structural models, the opening of the plug part is larger than the opening of the hanger.

[0016] The specific structure of the aforementioned support frame is as follows: the support frame includes a mounting plate connected to the circuit breaker switch body; a reference plate is connected to the mounting plate at a position away from the circuit breaker switch body; and the reference plate is provided with an internal threaded hole for connection to the active drive rod.

[0017] The selected bearing is a deep groove ball bearing.

[0018] To ensure a locking effect and facilitate torque measurement, the adjacent surfaces of the locking member and the insertion part are high-friction surfaces.

[0019] The beneficial effects of this utility model are as follows: This utility model is a circuit breaker switch opening and closing operating mechanism that facilitates torque measurement. Unlike conventional operating mechanisms that are large in size and integrate electric structures, this device has a lower overall weight, making it more flexible and convenient to use. Furthermore, the aforementioned active drive rod is driven by a lead screw, which has high transmission accuracy and strong load-bearing capacity. After being connected through an adaptive regulator, it can accommodate adjustment space and ensure that it can be connected to the opening and closing rods of circuit breaker switch bodies of various specifications when the active drive rod is reset to its initial state. Moreover, after the adaptive regulator is locked in the holding state, the opening and closing operation can be completed by using a torque wrench or other structure, and torque can be measured during the process.

[0030] Example

[0031] like Figure 1-4 The circuit breaker switch opening and closing operating mechanism shown is convenient for measuring torque. It includes a support frame 2 detachably connected to the circuit breaker switch body 1. The structure of the circuit breaker switch body 1 will not be described in detail. It should be noted that the support frame 2 connected to it can be freely replaced and disassembled. The structure is welded and adopts a lightweight design. Then, the support frame 2 is connected to the active drive rod 3 by thread. The central axis of the active drive rod 3 is on the same straight line as the central axis of the opening and closing rod 11 of the circuit breaker switch body 1. This ensures that the opening and closing rod 11 can be moved during the movement of the active drive rod 3 to complete the opening and closing operation. The active drive rod 3 is a threaded screw, which drives the opening and closing rod 11 by rotation. The method of rotating the active drive rod 3 can be a torque wrench. Therefore, the end of the active drive rod 3 away from the opening and closing rod 11 is a non-circular structure or other shape that cooperates with a torque wrench.

[0032] Furthermore, for applicability considerations, the end of the active drive rod 3 near the opening / closing lever 11 is rotatably connected to an adaptive regulator 5 via a bearing 4. The adaptive regulator 5 can only move along the central axis of the active drive rod 3. First, it should be noted that the bearing 4 is a deep groove ball bearing 4. And the adaptive regulator 5... Figure 4 The method of connection with it is such that, due to the action of the deep groove ball bearing, the above-mentioned adaptive regulator 5 will not rotate along with the active drive rod 3 during rotation, thereby ensuring that only upward pulling force is transmitted. The design of the above-mentioned structural components can ensure that the active drive rod 3 and the opening and closing rod 11 move synchronously and in the same direction.

[0033] Subsequently, a connector 6 is inserted and connected to the end of the adaptive regulator 5 away from the active drive rod 3. The connector 6 is detachably connected to the opening and closing rod 11. The connector 6 and the adaptive regulator 5 are detachably inserted and connected to facilitate separation of the two. The connector 6 can be directly fixed to the opening and closing rod 11 to ensure that the two can be synchronized without affecting the structural features of the opening and closing rod 11 itself.

[0034] The above method can be used to rotate the active drive rod 3 by using a torque wrench or similar detection equipment, which can indirectly drive the opening and closing lever 11 to move. During the movement, the force value at different stages can be detected. Based on the design of the above structure, the existence of the adaptive regulator 5 can not only guide and prevent synchronous rotation, but also make adaptive adjustments in the length direction.

[0035] Limited by the stroke and initial position of the opening and closing lever 11, directly using the method of rotating the active drive lever 3 to adapt it to the above-mentioned equipment can easily cause the problem of insufficient overall stroke. Furthermore, if the length of the active drive lever 3 is extended, in some cases, such as in a confined space, it will also affect the overall structural size of the equipment and affect its use. Therefore, the best approach is that the end position of the adaptive adjuster 5 near the connector 6 can be adjusted.

[0036] And such as Figure 5 , 6 As shown, the adaptive adjuster 5 comprises a sleeve portion 51 rotatably connected to the bearing 4 and a plug portion 52 connected to the connector 6. The plug portion 52 is plugged into the sleeve portion 51. This allows for the movable connection of the two structural components, thus achieving positional applicability. However, it cannot be used normally in this case because the plug portion 52 and the sleeve portion 51 cannot be fixed in position, thus preventing the transmission of tensile force during use. To address this issue, the most important feature is that, in order to achieve fixation at different positions, a locking member 53 is provided on the side of the sleeve portion 51 to press against the plug portion 52. The locking member 53 allows for fixation, enabling the transmission of tensile force in the first instance. Furthermore, the locking member 53 can be threaded.

[0037] Subsequently, the detachable connection is achieved by providing an opening at the end of the insertion part 52 away from the sleeve part 51, which is then fixed by a pin. To accommodate different structural models, the opening of the insertion part 52 is larger than the opening of the hanger 6. However, this leads to a new problem: after insertion, if the pin is located in the middle or lower part of the opening, it cannot transmit tension immediately. Therefore, the following design is required: For easy positioning and fixing, the insertion part 52 is elastically connected to the sleeve part 51, with the elastic direction along the length of the central axis of the active drive rod 3. In this way, after pulling the above-mentioned plug-in part 52 and connecting it to the locking member through the pin, and then releasing the hand, it can achieve an upward position of resistance under the action of elastic connection. At this time, it can be fixed by the locking member 53, and then the pulling force can be transmitted immediately. The above-mentioned elastic connection is that a spring 54 is provided between the plug-in part 52 and the sleeve part 51. The spring 54 only provides the pulling force to pull the plug-in part 52 to move closer to the active drive rod 3.

[0038] Finally, as a preferred embodiment, the specific structure of the support frame 2 is as follows: the support frame 2 includes a mounting plate 22 connected to the circuit breaker switch body 1, and the mounting plate 22 is connected to a reference plate 21 at a position away from the circuit breaker switch body 1, and the reference plate 21 is provided with an internal threaded hole for connection with the active drive rod 3.

[0039] Furthermore, in the above structure, in order to ensure the locking effect and facilitate torque measurement, the adjacent surfaces of the locking member 53 and the insertion part 52 are high-friction surfaces.
