Description

Technical Field

[0001] This utility model relates to the field of electrical device technology, and in particular to a tripping device. Background Technology

[0002] Tripping devices (such as air switches and residual current devices) are important equipment that automatically disconnect the circuit when an abnormal situation such as overload or short circuit occurs in the circuit, so as to protect electrical equipment, prevent electrical fires, and ensure personal and property safety. They are commonly used in power systems, construction and other technical fields.

[0003] Existing tripping devices typically only indicate the tripping status via mechanical levers, lacking active alarm functions. This makes it difficult for staff to detect abnormal tripping in a timely manner, which can easily lead to safety hazards and affect power supply efficiency.

[0004] Therefore, a tripping device that can send a signal to staff when the circuit breaker trips is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a tripping device that can send a signal to staff when a tripping occurs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tripping device, including a housing, wherein a switch lever is rotatably provided on one side of the housing;

[0007] A triggering component, including a trigger block, is disposed at one end of the switch plate that extends into the housing;

[0010] A control component is disposed between the sound and light unit and the power supply unit, one end of which is detachably connected to the trigger block to perform on / off control.

[0011] Furthermore, the trigger block is slidably inserted into the switch dial plate, and a first elastic unit is provided between its extended end and the switch dial plate to apply an elastic force to the trigger block in the direction of approaching the switch dial plate;

[0012] The switch plate is provided with a switching component, including a switching plate, which is coaxially rotatably disposed inside the switch plate. One end of the switching plate is in contact with the trigger block and is used to control the trigger block to perform telescopic movement in the switch plate.

[0013] A limiting component is disposed on the switch dial plate and located on one side of the switching plate, for constraining the rotation of the switching plate.

[0014] Furthermore, the limiting component includes two opposing limiting balls that are slidably disposed in the switch dial;

[0016] Furthermore, the control component includes a first conductive unit, which is pivotally connected to the housing and located on one side of the trigger block, its power supply terminal is connected to the power supply unit, and a torsion spring is provided at the pivot point;

[0017] The second conductive unit is disposed inside the housing and located on one side of the first conductive unit, with one end of it electrically connected to the acousto-optic unit.

[0028] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-5 The present invention discloses a tripping device, including a housing 02, a switch lever 01 rotatably provided on one side of the housing 02, and a chamber 011 opened inside the housing 02;

[0030] Triggering component 1 includes trigger block 11, which is disposed at one end of switch plate 01 that extends into housing 02;

[0031] The response component 2 includes a power supply unit 21, which is disposed inside the housing 02;

[0032] The sound and light unit 22 is located on the outside of the housing 02 and is electrically connected to the power supply unit 21, and is used to generate a sound and light alarm for the staff.

[0033] The control component 23 is located between the sound and light unit 22 and the power supply unit 21. One end of the control component 23 is detachably connected to the trigger block 11 to perform on / off control between the power supply unit 21 and the sound and light unit 22.

[0034] In practice, when the circuit trips and the power is cut off, the thermal element drives the switch lever 01 to close through the trip unit. At this time, the switch lever 01 rotates downward and drives the abutment block to rotate towards the control component 23 until the abutment block is connected to the control component 23, and the power supply unit 21 and the sound and light unit 22 are connected. The sound and light unit 22 will generate a sound and light alarm to remind the staff. When the staff rotates the switch lever 01 upward to reset it, the switch lever 01 drives the abutment block to rotate together until the abutment block is separated from the control component 23. At this time, the power supply unit 21 and the sound and light unit 22 are disconnected, and the sound and light unit 22 no longer works.

[0035] In this invention, through the cooperation between the triggering component 1 and the response component 2, when the circuit trips, the switch toggle 01 drives the trigger block 11 to rotate and make it contact the control component 23. At this time, the control component 23 makes the power supply unit 21 and the sound and light unit 22 pass through, and the sound and light unit 22 generates a sound and light alarm, so that the staff can notice the tripping abnormality at the first time and deal with the problem, reduce safety hazards, and ensure power supply efficiency.

[0036] Preferably, the power supply unit 21 can use a battery pack from the prior art.

[0037] Preferably, the sound and light unit 22 can be a sound and light alarm device in the prior art.

[0038] In one embodiment, the trigger block 11 is slidably connected to the switch dial 01 and one end extends into the chamber 011. A first elastic unit 12 is also provided between the trigger block 11 and the chamber 011 to apply an elastic force to the trigger block 11 in the direction close to the switch dial 01.

[0039] The switch lever 01 is also provided with an adjustment groove 012;

[0040] The switch dial 01 is provided with a switching component 3, including a switching plate 31 coaxially rotatably disposed in the switch dial 01. The switching plate 31 is composed of an adjustment section 311 disposed in the chamber 011 and in contact with the trigger block 11, and a toggle section 312 extending out of the chamber 011 and disposed in the adjustment groove 012. Its rotation axis is located between the adjustment section 311 and the toggle section 312. When the toggle section 312 rotates, the adjustment section 311 rotates in the chamber 011 relative to the rotation direction of the toggle section 312. A torsion spring (not shown in the figure) is provided at the rotation connection of the switching plate 31 to apply a downward rotational torque to the toggle section 312.

[0041] The limiting component 32 is disposed in the adjusting groove 012 and located on one side of the toggle section 312, and is used to constrain the rotation of the switching plate 31.

[0042] With this design, when active tripping is required, the response component 2 does not need to operate. The operator rotates the toggle section 312 upwards until it contacts the limit component 32 and prevents it from rotating. At this time, the torsion spring is compressed, and the adjusting section 311 rotates downwards until it separates from the trigger block 11. The first elastic unit 12 loses its constraint and applies a spring force to the trigger block 11 towards the switch plate 01 until the trigger block 11 is retracted into the chamber 011. Then, the operator rotates the switch plate 01, and the trigger block 11 will not connect with the control component 23. After the operation is completed, the operator resets the switch plate 01 and rotates the toggle section 312 downwards until it separates from the limit component 32. At this time, the torsion spring loses its constraint and drives the toggle section 312 to rotate downwards. At the same time, the toggle section 312 rotates upwards and applies a squeezing force to the trigger block 11 away from the chamber 011. The trigger block 11 extends, and the first elastic unit 12 is compressed again.

[0043] Preferably, the first elastic unit 12 can be a spring from the prior art.

[0044] In one embodiment, two opposing sliding grooves 013 are formed on the corresponding sidewall of the adjusting groove 012;

[0045] The limiting component 32 includes limiting balls 321 that are slidably disposed in corresponding slide grooves 013. Each limiting ball 321 is provided with a second elastic unit 322 between itself and the switch plate 01, which is used to apply an elastic force to the corresponding limiting ball 321 in the direction of approaching the switching plate 31.

[0046] With this design, when the switching plate 31 rotates upward and the actuating section 312 contacts each of the limiting balls 321, as the switching plate 31 continues to rotate, the actuating section 312 applies a squeezing force to each of the limiting balls 321 in a direction away from the switching plate 31. Each of the limiting balls 321 is compressed and retracts into the corresponding slide groove 013, and each of the second elastic units 322 is compressed until the actuating section 312 separates from each of the limiting balls 321. At this time, each of the second elastic units 322 loses its constraint and causes each of the limiting balls 321 to extend out of the corresponding slide groove 013 and prevent the actuating section 312 from rotating downward. When the switching plate 31 rotates downward, the actuating section 312 contacts each of the limiting balls 321 again and overcomes the elastic force of each of the second elastic units 322 by manual force until the actuating section 312 separates from each of the limiting balls 321.

[0047] It should be noted that the sum of the elastic forces of the two second elastic units 322 is greater than the torsion force of the torsion spring at the rotating connection of the switching plate 31, but less than the sum of the torsion spring torsion force and the manual force applied, so that each limiting ball 321 can properly constrain the rotation of the switching plate 31.

[0048] Preferably, the second elastic unit 322 can be a spring from the prior art.

[0049] In one embodiment, the trigger block 11 is made of an insulating material;

[0050] The control component 23 includes a first conductive unit 231 pivotally connected to the housing 02 and located on one side of the trigger block 11. The first conductive unit 231 is set at a height higher than the trigger block 11. Its power supply terminal is electrically connected to the power supply unit 21. A torsion spring (not shown in the figure) is provided at the pivot point. The torsion spring applies a downward rotational torque to the first conductive unit 231. When the trigger block 11 rotates upward, it can contact the first conductive unit 231 and apply an upward rotational squeezing force to it.

[0051] The second conductive unit 232 is disposed inside the housing 02 and located on one side of the first conductive unit 231. One end of it is electrically connected to the acoustic-optical unit 22. When the first conductive unit 231 contacts the second conductive unit 232, the circuit path between the power supply unit 21 and the acoustic-optical unit 22 is established.

[0052] With this design, when the circuit trips and the power is cut off, the switch lever 01 drives the abutment block to rotate upward until the trigger block 11 contacts the first conductive unit 231 and applies an upward rotating squeezing force to it. At this time, the first conductive unit 231 contacts the second conductive unit 232, and the circuit between the power supply unit 21 and the sound and light unit 22 is closed. The torsion spring at the pivot of the first conductive unit 231 is compressed. When the operator opens the switch lever 01 again, the switch lever 01 drives the abutment block to rotate downward, and the abutment block separates from the first conductive unit 231. The torsion spring loses its constraint and drives the first conductive unit 231 to move downward, thereby separating it from the second conductive unit 232. The circuit between the power supply unit 21 and the sound and light unit 22 is broken.

[0053] Preferably, both the first conductive unit 231 and the second conductive unit 232 can be made of elastic copper sheet;

[0054] In one embodiment, the end of the trigger block 11 that extends into the chamber 011 is provided with a limiting block 4 for preventing the switching plate 31 from rotating.

[0055] With this design, when the trigger block 11 extends out of the chamber 011, the switching plate 31 drives the adjusting section 311 to rotate upward under the torque of the corresponding torsion spring until it contacts the limiting block 4. At this time, the limiting block 4 prevents the adjusting section 311 from continuing to rotate, thereby avoiding the accidental separation of the switching plate 31 and the trigger block 11, which would cause the trigger block 11 to retract into the chamber 011.

[0056] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0057] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0058] Additionally, "multiple" refers to two or more.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
