Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a modular switching mechanism. Background Technology

[0002] Existing modular disconnect switches are typically formed by connecting and combining a control module and at least one disconnect switch module. The control module controls multiple disconnect switch modules to disconnect simultaneously. However, the opening and closing speed of the disconnect switch is determined by the operating speed of the control module. Therefore, when the control module is manually operated, the speed at which the operator rotates the operating mechanism inside the control module is the opening and closing speed of the disconnect switch module. Since the speed of manual operation is relatively limited, if the opening and closing speed is too slow, it can easily lead to a longer arc existence time, poor arc extinguishing effect, and thus damage to the disconnect switch module, affecting its service life and safety. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular switching mechanism.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A modular switching mechanism, comprising: frame, A rotating shaft is provided along the width of the frame and is capable of rotating relative to the frame between a first position and a second position. The rotating shaft is used to switch the linked switch contact system from an on state to an off state when it moves from the first position to the second position. An operating shaft is provided along the height of the frame and is capable of rotating relative to the frame between an on and off position. The operating shaft is used to drive the rotation of the rotating shaft. An actuator is disposed at the bottom of the operating shaft and is configured to drive the rotating shaft to move, and at least one spring is provided between the actuator and the frame; The top pressing component is symmetrically arranged on both sides of the rotating shaft, and a slot is provided on the side facing the rotating shaft. A double torsion spring is provided between the rotating shaft and the top pressing component. The straight arm of the double torsion spring is fixedly connected to the rotating shaft, and its middle section is locked in the slot. The double torsion spring provides force to the rotating shaft when it accelerates from the first position to the second position.

[0005] The rotating shaft is provided with a linkage part, and the actuator is provided with a first driving part on its upper side. When the rotating shaft is in the first position, the linkage part is located on the rotation path of the first driving part.

[0006] The surface of the operating shaft is provided with a second driving part for moving the rotating shaft from the second position to the first position.

[0007] The rotating shaft has a concave surface at one end and a convex surface at the other end.

[0008] The operating shaft surface is provided with a gear, and the upper side of the top pressing member is provided with a slider. The two ends of the slider are respectively in contact with the upper surfaces of the top pressing members on both sides, and a groove is formed in the middle for the operating shaft to pass through. The inner wall of the groove is provided with a rack that meshes with the gear.

[0009] The frame is also provided with a handle assembly for driving the operating shaft to move between the on and off positions.

[0010] The handle assembly includes a handle body detachably connected to the operating shaft. The front end of the handle body is provided with a stop shaft arranged along the height direction of the frame. The handle body is also provided with a rotatable latch. The latch has an initial position and a locking position where relative rotation causes the stop shaft to move downward and form a limiting engagement with the frame. A reset member is provided between the latch and the handle body.

[0011] The latch is provided with a U-shaped groove on the side near the stop shaft, and the stop shaft is provided with guide grooves on both sides that can cooperate with the U-shaped groove.

[0012] The front end of the U-shaped slot is provided with a protrusion, and the guide groove is raised inward from the opening.

[0013] The latch has a lock hole.

[0014] The beneficial effects of this utility model are as follows: the operating shaft drives the actuator and the rotating shaft to rotate, and the spring of the actuator maintains the connected state through the dead point. When the actuator is manually operated to disconnect, the actuator is slightly rotated to reset the spring, accelerate the rotation of the actuator, and the actuator touches the rotating shaft, which resets the double torsion spring that was originally compressed by the rotating shaft, thereby accelerating the movement to the second position, thus making the disconnection faster.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] like Figure 1 As shown, a modular switching mechanism can be connected to disconnect switches on both sides. When operating from the front, rotating the front operating shaft drives the rotating shaft to rotate, thereby driving the adjacent disconnect switch module to perform opening and closing actions. Furthermore, the double torsion springs of the actuator and rotating shaft are used to accelerate the action speed, thereby effectively improving the opening action speed of the adjacent disconnect switch module, shortening the arc existence time in the disconnect switch module, improving the arc extinguishing effect, and effectively extending the service life of the disconnect switch module.

[0029] The modular switching mechanism features a concave-convex design on both ends of the rotating shaft, which causes the moving contacts of the disconnecting switch module connected to it to move in tandem with it.

[0030] like Figure 2 and Figure 3As shown, the modular switching mechanism includes a frame and a rotating shaft and an operating shaft disposed within the frame. The rotating shaft is designed to be perpendicular to the operating shaft, and the operating shaft can drive the rotating shaft to move. At the same time, the bottom of the operating shaft is provided with an actuator that rotates synchronously with it. When the actuator rotates, it compresses the spring to store force. When the drive shaft rotates, it can compress the double torsion spring to store force.

[0031] The frame 100 includes three housings: upper, middle, and lower. The rotating shaft is restricted by the middle and lower housings, and both ends of the shaft are exposed to facilitate cooperation with adjacent disconnect switches. The operating shaft passes through the three housings from top to bottom. The rotation of the operating shaft can drive the rotating shaft to rotate. At the same time, the bottom of the operating shaft is equipped with a linkage actuator, which is a ring-shaped structure that can rotate with the rotation of the operating shaft.

[0032] like Figure 2 As shown, X represents the length direction of the frame, Y represents the width direction of the frame, and Z represents the height direction of the frame.

[0033] A rotating shaft 300, arranged along the width of the frame, is rotatable relative to the frame 100 between a first position and a second position. The rotating shaft 300 is used to switch the linked switch contact system from an on state to an off state when moving from the first position to the second position; the first position is as follows: Figure 4 As shown, the second position is as follows Figure 5 and Figure 6 As shown.

[0034] An operating shaft 400 is provided along the height direction of the frame, and it is rotatable relative to the frame 100 between an on position and an off position. The operating shaft 400 is used to drive the rotation of the rotating shaft 300. An actuator 500 is disposed at the bottom of the operating shaft 400 and is configured to drive the rotating shaft 300 to move. At least one spring 600, preferably two springs, is provided between the actuator 500 and the frame 100. Both springs can be transferred from a first low-energy position to a mid-dead position and from a second low-energy position to a mid-dead position by the rotation of the operating shaft, such that the energy required to transfer the spring to the mid-dead position comes from the rotation of the operating shaft 400.

[0035] The rotating shaft 300 is provided with a linkage part 310, and the actuator 500 is provided with a first driving part 510 on its upper side. When the rotating shaft 300 is in the first position, the linkage part 310 is located on the rotation path of the first driving part 510.

[0036] The actuator is adapted to rotate relative to the frame about a rotation axis and is adapted to cooperate with the drive shaft to rotate the drive shaft toward a second position. The actuator and the spring are located in the lower portion of the frame 2. The actuator includes a first drive portion adapted to cooperate with a linkage disposed on the drive shaft to transmit torque from the actuator to the drive shaft. Mechanical contact between the first drive portion and the linkage causes the drive shaft to rotate to an intermediate position between the first position and the second position.

[0037] The rotation axis of the operating shaft is perpendicular to the rotation axis of the drive shaft. The rotation axis of the actuator coincides with the rotation axis of the operating shaft. The operating shaft extends through the drive shaft.

[0038] The pressing members 700 are symmetrically arranged on both sides of the rotating shaft 300, and a retaining slot 710 is provided on the side facing the rotating shaft 300, such as... Figure 7 As shown, a double torsion spring 800 is provided between the rotating shaft 300 and the pressing member 700. The straight arm of the double torsion spring 800 is fixedly connected to the rotating shaft 300, and its middle section is locked in the bayonet. The double torsion spring 800 provides force to the rotating shaft 300 when it accelerates from the first position to the second position.

[0039] The surface of the operating shaft 400 is provided with a second drive unit 410 for moving the rotating shaft 300 from the second position to the first position. Through the design of the second drive unit 410, when the operating shaft rotates, the second drive unit can drive the rotating shaft to rotate.

[0040] The rotating shaft 300 has a concave surface at one end and a convex surface at the other. This concave-convex design is used to form a linkage with the moving contact of the disconnecting switch, so as to realize the transmission of force between the two.

[0041] like Figure 8 As shown, the operating shaft 400 has a gear 420 on its surface, and the top pressing member 700 has a slider 900 on its upper side. The slider 900 has two ends that contact the upper surfaces of the top pressing members on both sides, and a groove 910 is formed in the middle through which the operating shaft can pass. The inner wall of the groove 910 has a rack 920 that meshes with the gear. When the operating shaft rotates, it can drive the slider to slide relative to it, thereby enabling it to be linked with a trigger switch located between the upper and middle shells to achieve status indication. In this embodiment, the trigger switch is not shown.

[0042] like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the frame 100 is also provided with a handle assembly 200 for driving the operating shaft 400 to move between the on and off positions.

[0043] The handle assembly 200 includes a handle body 210 detachably connected to the operating shaft. The front end of the handle body is provided with a stop shaft 230 arranged along the height direction of the frame. The handle body is also provided with a rotatable latch 220. The latch has an initial position and a locking position where relative rotation causes the stop shaft to move downward and form a limiting engagement with the frame. A reset member is provided between the latch and the handle body.

[0044] The handle body and the operating shaft are interlocked and fixedly connected by bolts, making them a single unit. This allows the operation of the handle to drive the operating shaft synchronously. A positioning hole is provided on the housing. When the stop shaft is in the locked position, it is inserted into the positioning hole, thereby restricting the rotation of the handle assembly. When disconnected, the operation of restricting closure can be achieved by locking the handle assembly. At the same time, a spring is provided between the stop shaft and the handle body for the stop shaft to reset.

[0045] A groove is directly provided on the handle body, and the latch is rotatably disposed in the groove. In the initial position, the latch is aligned with the upper surface of the handle body, thus hiding the latch. When locking is required, the lower end of the latch exposed at the bottom is pressed and rotated upward, thereby causing the other end of the latch to drive the stop shaft to move downward.

[0046] The latch is provided with a U-shaped groove 221 on the side near the stop shaft, and the stop shaft is provided with guide grooves 231 on both sides that can cooperate with the U-shaped groove. The two cooperate to achieve linkage. The latch is engaged with the stop shaft so that the rotation of the latch drives the stop shaft to move.

[0047] Furthermore, by setting a reset element, which is a spring, on the latch and the handle body, the latch can be reset by the reset element when it is released by external force.

[0048] The front end of the U-shaped slot is provided with a protrusion 222, and the guide groove 231 is raised inward from the opening. The protrusion and the guide groove cooperate to drive the stop shaft to move downward relative to each other using the guide path.

[0049] The latch is provided with a lock hole 223, which is used for padlock to prevent it from being accidentally operated when it is in the open position.

[0050] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
