Anti-vibration tripping isolating switch operating device

Abstract

This utility model discloses an anti-vibration tripping disconnect switch operating device, including a first handle, a connecting plate rotatably connected inside the first handle, a second handle rotatably connected to the outer side of the connecting plate away from the first handle, and an operating head fixedly connected to the outer end of the first handle away from the connecting plate. The operating head has a groove inside, and a rotating shaft is disposed inside the groove, rotatably connected to the operating head. Under the torque of a torsion spring, the stop bar of this anti-vibration tripping disconnect switch operating device will abut against the operating head. When the operating head engages with the switch hook, the switch hook will first lower the stop bar and enter the inner side of the operating head. After the switch hook has completely passed the stop bar, the torque of the torsion spring will cause the stop bar to abut against the operating head again. The stop bar can prevent the switch hook from tripping due to vibration between the switch hook and the operating head. After the operation is completed, the stop bar has an L-shaped structure, allowing the switch hook to disengage from the operating head.

Description

Technical Field

[0001] This utility model relates to the field of power construction tools technology, and more specifically, to an anti-vibration tripping disconnect switch operating device. Background Technology

[0002] A disconnecting switch is a switching device mainly used for isolating power supplies, switching operations, and connecting and disconnecting small current circuits. When in the open position, the disconnecting switch has an insulation distance between the contacts that meets the specified requirements and a clear disconnection mark; when in the closed position, it is a switching device that can carry current under normal circuit conditions and current under abnormal conditions for a specified time.

[0003] Operating disconnect switches requires operating devices such as operating levers. However, some existing operating levers have only a simple U-shaped operating head without an anti-disengagement structure. During the operation of the disconnect switch, vibration may cause the operating head to disengage from the switch hook, resulting in operation interruption. Therefore, we provide a vibration-resistant disconnect switch operating device. Utility Model Content

[0004] The purpose of this invention is to provide an anti-vibration tripping disconnect switch operating device to solve the problems mentioned in the background art.

[0005] Currently, some existing operating levers have only a simple U-shaped operating head without an anti-disengagement structure. During the operation of the disconnecting switch, vibration may cause the operating head to disengage from the switch hook, resulting in an interruption of operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-vibration tripping disconnect switch operating device includes a first handle, a connecting plate rotatably connected inside the first handle, a second handle rotatably connected to the outer side of the connecting plate away from the first handle, an operating head fixedly connected to the outer end of the first handle away from the connecting plate, an internal groove of the operating head, a rotating shaft disposed inside the groove, the rotating shaft rotatably connected to the operating head, a stop rod sleeved on the outer side of the rotating shaft, the stop rod fixedly connected to the rotating shaft, and a torsion spring sleeved on the outer side of the rotating shaft between the stop rod and the groove, one end of the torsion spring fixedly connected to the operating head, and the other end of the torsion spring fixedly connected to the stop rod.

[0008] Preferably, the first handle and the second handle have the same specifications.

[0009] Preferably, the operating head has a U-shaped structure and the stop lever has an L-shaped structure.

[0010] Preferably, the connecting plate has a groove inside, and a sliding plate is slidably connected inside the groove. There are two sliding plates, and a spring is fixedly connected between the two sliding plates. A locking block is fixedly connected to the outside of the sliding plate away from the spring. The locking block penetrates the connecting plate vertically and extends to the outside of the connecting plate. The locking block is slidably connected to the connecting plate. The first handle and the second handle both have slots inside, and the slots cooperate with the locking blocks.

[0011] Preferably, the outer wall of the slide plate is fitted to the inner wall of the slide groove.

[0012] Preferably, a pressure block is fixedly connected to the outer side of the slide plate near the locking block. The pressure block penetrates the connecting plate vertically and extends to the outside of the connecting plate. The pressure block is slidably connected to the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Pulling the first and second handles directly causes the slide plate in the groove to engage with the locking blocks on the first and second handles under the spring force, thus limiting the movement of the first and second handles from the connecting plate. Folding is then possible by pressing the slide plate with the pressure block to disengage the locking blocks from the locking slots. For the operating head, the stop lever is pressed against the operating head under the torque of the torsion spring. When the operating head engages with the switch hook, the switch hook first lowers the stop lever and enters the inside of the operating head. After the switch hook has completely passed the stop lever, the torque of the torsion spring causes the stop lever to engage with the operating head again. The stop lever prevents the switch hook from disengaging from the operating head due to vibration. After operation, the L-shaped structure of the stop lever allows the switch hook to disengage from the operating head. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 6 The anti-vibration tripping disconnect switch operating device includes a first handle 1, a connecting plate 2 rotatably connected inside the first handle 1, a second handle 3 rotatably connected to the outer side of the connecting plate 2 away from the first handle 1, an operating head 4 fixedly connected to the outer end of the first handle 1 away from the connecting plate 2, a groove 5 inside the operating head 4, a rotating shaft 6 disposed inside the groove 5, the rotating shaft 6 rotatably connected to the operating head 4, a stop rod 7 sleeved on the outer side of the rotating shaft 6, the stop rod 7 fixedly connected to the rotating shaft 6, and a torsion spring 8 sleeved on the outer side of the rotating shaft 6, located between the stop rod 7 and the groove 5. One end of the spring 8 is fixedly connected to the operating head 4, and the other end of the torsion spring 8 is fixedly connected to the stop rod 7. Under the torque of the torsion spring 8, the stop rod 7 will press against the operating head 4. When the operating head 4 is engaged with the switch hook, the switch hook will first lower the stop rod 7 and enter the inside of the operating head 4. After the switch hook has completely passed the stop rod 7, the torque of the torsion spring 8 will drive the stop rod 7 to press against the operating head 4 again. The stop rod 7 can prevent the switch hook from disengaging from the operating head 4 due to vibration. After the operation is completed, since the stop rod 7 has an L-shaped structure, the switch hook can be disengaged from the operating head 4.

[0024] Furthermore, the first handle 1 and the second handle 3 are of the same specifications, and the first handle 1 and the second handle 3 are connected by a connecting plate 2. Under the action of the connecting plate 2, the first handle 1 and the second handle 3 can be folded and unfolded.

[0025] Furthermore, the operating head 4 has a U-shaped structure, and the stop bar 7 has an L-shaped structure. The L-shaped stop bar 7 facilitates the release of the switch hook from the operating head 4.

[0026] Furthermore, the connecting plate 2 has a groove 9 inside, and a slide plate 10 is slidably connected inside the groove 9. There are two slide plates 10, and a spring 11 is fixedly connected between the two slide plates 10. A locking block 12 is fixedly connected to the outside of the slide plate 10 away from the spring 11. The locking block 12 penetrates the connecting plate 2 vertically and extends to the outside of the connecting plate 2. The locking block 12 is slidably connected to the connecting plate 2. The first handle 1 and the second handle 3 both have a slot 13 inside. The slot 13 works in conjunction with the locking block 12. After the first handle 1 and the second handle 3 are unfolded, the slide plate 10 in the groove 9 will move automatically under the elastic force of the spring 11, and drive the locking block 12 to engage with the slot 13. The locking block 12 and the slot 13 are used to limit the distance between the first handle 1 and the second handle 3 and the connecting plate 2.

[0027] Furthermore, the outer side wall of the slide plate 10 is in contact with the inner side wall of the slide groove 9, allowing the slide plate 10 to slide within the slide groove 9. Because the slide plate 10 is in close contact with the slide groove 9, the slide plate 10 is limited by the slide groove 9, ensuring the stability of the slide plate 10 when it moves.

[0028] Furthermore, a pressure block 14 is fixedly connected to the outside of the skateboard 10 near the locking block 12. The pressure block 14 penetrates vertically through the connecting plate 2 and extends to the outside of the connecting plate 2. The pressure block 14 is slidably connected to the connecting plate 2. When the locking block 12 on the skateboard 10 is engaged with the locking slot 13 on the first handle 1 and the second handle 3, the user cannot directly press the locking block 12. By setting the pressure block 14, it is more convenient for the user to press the skateboard 10, so that the skateboard 10 drives the locking block 12 to disengage from the locking slot 13. When the locking block 12 disengages from the locking slot 13, the user can rotate and fold the first handle 1, the second handle 3 and the connecting plate 2 to shorten the overall length and make it more convenient to carry.

[0029] The usage steps of this utility model are as follows: When using this anti-vibration tripping disconnect switch operating device, under normal circumstances, the first handle 1 and the second handle 3 can be folded up under the action of the connecting plate 2, making the overall length shorter and more convenient to carry. The user directly pulls the first handle 1 and the second handle 3. Under the elastic force of the spring 11, the slide plate 10 in the slide groove 9 will drive the locking block 12 to engage with the locking grooves 13 on the first handle 1 and the second handle 3, thereby limiting the distance between the first handle 1 and the second handle 3 and the connecting plate 2. Folding is required only by pressing the sliding plate 1 with the pressure block 14. Press down to disengage the locking block 12 from the locking slot 13. For the operating head 4, under the torque of the torsion spring 8, the stop rod 7 will abut against the operating head 4. When the operating head 4 is engaged with the switch hook, the switch hook will first lower the stop rod 7 and enter the inside of the operating head 4. After the switch hook has completely passed the stop rod 7, the torque of the torsion spring 8 will drive the stop rod 7 to abut against the operating head 4 again. The stop rod 7 can prevent the switch hook from disengaging from the operating head 4 due to vibration. After the operation is completed, since the stop rod 7 has an L-shaped structure, the switch hook can be disengaged from the operating head 4.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
