[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] Please refer to Figure 1 and Figure 2 , an isolating switch for conveniently observing the opening and closing states, comprising a switch body 1 and an opening and closing indicating device;

[0031] The opening and closing indicating device comprises a transmission component and an opening and closing indicating component;

[0032] The opening and closing indication assembly is arranged on the switch body 1, and a swinging member 3 and an opening mark 4 and a closing mark 5 corresponding to the swinging member 3 are provided on the opening and closing indication assembly. The swinging member 3 is connected to the handle 2 of the switch body 1 through a transmission assembly.

[0033] When the handle 2 is closed, the transmission assembly drives the swing member 3 to point to the closing mark 5;

[0034] When the knife handle 2 is disconnected, the transmission assembly drives the swing member 3 to point to the opening mark 4.

[0035] From the above description, it can be seen that the beneficial effects of the utility model are: a switch opening and closing indication device is added to the switch body 1, which is specifically composed of a transmission assembly and a switch opening and closing indication assembly. During the switch opening and closing process, the handle 2 of the switch body 1 drives the swinging member 3 to move through the transmission assembly when it swings, so that the swinging member 3 points to the switch opening mark 4 or the switch closing mark 5 respectively; when the operator cannot see clearly whether the handle 2 is in place for opening and closing, the operator can easily observe and judge whether the switch opening and closing is in place through the direction of the swinging member 3, thereby ensuring the safe operation of the live equipment.

[0036] Furthermore, the opening and closing indication component also includes an indication sign;

[0037] The indicator plate is arranged on the switch body 1, and the opening mark 4 and the closing mark 5 are respectively located at different positions on the indicator plate;

[0038] The swing member 3 is rotatably arranged on the switch body 1, and one end of the swing member 3 is used to point to the opening mark 4 and the closing mark 5 respectively through rotation;

[0039] The transmission assembly is transmission-connected to the other end of the swing member 3 .

[0040] From the above description, it can be seen that the opening and closing indication is specifically distinguished by setting an indicator sign so that the swing member 3 points to different positions on the indicator sign. Its composition structure and operating principle are relatively simple, easy to install, highly applicable and low cost.

[0041] Further, the transmission assembly includes a stopper 6 and an automatic reset ejector 7;

[0042] The stopper 6 is arranged on the end of the swinging member 3 away from the indicator plate, and the stopper 6 corresponds to the knife handle 2, and the knife handle 2 presses against the stopper 6 when the switch is closed;

[0043] The automatic reset ejector 7 is arranged on the switch body 1 , and the movable end of the automatic reset ejector 7 is arranged toward the bottom of the stopper 6 .

[0044] From the above description, it can be seen that a stopper 6 is provided at the end of the swinging member 3, and the stopper 6 cooperates with the tool handle 2, and changes the direction of the other end of the swinging member 3 through the lever principle, and automatically resets through the automatic reset ejector 7, so as to cater to the swinging action of the tool handle 2 when opening and closing the switch, and flexibly switches to indicate the open state and the closed state.

[0045] Further, the sign includes a first indicating portion and a second indicating portion having different shapes;

[0046] The opening mark 4 is located on the first indicating part, and the closing mark 5 is located on the second indicating part.

[0047] From the above description, it can be seen that in addition to some differences such as text marks, the signboard is divided into a first indicator part and a second indicator part with different shapes. The first indicator part and the second indicator part are respectively used to place the opening mark 4 and the closing mark 5, so that the difference between opening and closing is more conspicuous, so that the operating personnel can make intuitive judgments quickly and reduce the impact of environmental factors on them.

[0048] Furthermore, the opening and closing indication assembly also includes an adapter plate 8;

[0049] The adapter plate 8 is connected to the wiring board of the switch body 1 , and the indicator plate is arranged on the adapter plate 8 .

[0050] From the above description, it can be seen that when the terminal board of the switch body 1 is too small or insufficient to support the sign, the sign can be installed by adding an adapter plate 8 to ensure that the sign is firmly set on the switch body 1 and reduce the difficulty of maintenance.

[0051] Furthermore, the automatic reset ejector 7 is a spring;

[0052] The bottom of the stopper 6 is connected to the switch body 1 through a spring;

[0053] When the knife handle 2 does not press against the stopper 6, the spring is in the original length state.

[0054] From the above description, it can be seen that the automatic reset ejector 7 relies on the elastic force of the spring to control the swing member 3 to reset, and it has a simple structure, sensitive response, and convenient installation.

[0055] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present utility model is:

[0056] An isolating switch that is easy to observe the opening and closing status, such as Figure 1 and Figure 2 As shown, it includes a switch body 1 and an opening and closing indicating device; the opening and closing indicating device includes a transmission component and an opening and closing indicating component;

The swing member 3 is rotatably arranged on the switch body 1, and one end of the swing member 3 is used to point to the opening mark 4 and the closing mark 5 respectively through rotation; the transmission assembly is transmission-connected to the other end of the swing member 3.

[0058] Among them, the stopper 6 is arranged on the end of the swing member 3 away from the indicator plate, and the stopper 6 corresponds to the knife handle 2, and the knife handle 2 presses against the stopper 6 when closing the switch; the automatic reset ejector 7 is arranged on the switch body 1, and the movable end of the automatic reset ejector 7 is arranged toward the bottom of the stopper 6. When the knife handle 2 is closed, the transmission component drives the swing member 3 to point to the closing mark 5; when the knife handle 2 is disconnected, the transmission component drives the swing member 3 to point to the opening mark 4. As shown in the figure. The operation process of an isolating switch that is convenient for observing the opening and closing states is as follows:

[0059] like Figure 1 As shown, when the handle 2 of the switch body 1 is in the open state, that is, at this time, the handle 2 does not press the block 6; one end of the swing member 3 with the block 6 is supported by the automatic reset ejection member 7, so it will not automatically swing downward; so that the other end of the swing member 3 points to the closing mark 5, that is, it is in the initial state; wherein the automatic reset ejection member 7 is a spring; the bottom of the block 6 is connected to the switch body 1 through the spring; when the handle 2 does not press the block 6, the spring is in the original length state.

[0060] like Figure 2 As shown, when the handle 2 of the switch body 1 is in the closed state, that is, the handle 2 has fallen and pressed the stopper 6, under the action of pressure, one end of the swing member 3 rotates downward, so that the movable end of the automatic reset ejector 7 is compressed, and the other end of the swing member 3 rotates upward, thereby pointing to the closed position;

[0061] When the knife handle 2 is turned from the closed state to the open state, the movable end of the automatic reset ejector 7 pushes up, so that the swing member 3 is reset and points to the open position again.

[0062] In this embodiment, the opening and closing indication assembly further includes an indication board; the indication board includes a first indication part and a second indication part with different shapes; the opening mark 4 is located on the first indication part, and the closing mark 5 is located on the second indication part. As a preferred embodiment, the difference between the first indication part and the second indication part can be a different shape such as a round sign and a square sign, or a different color such as a red sign and a green sign.

[0063] In addition, the opening and closing indication component also includes an adapter plate 8; the adapter plate 8 is connected to the terminal board of the switch body 1, and the indication sign is arranged on the adapter plate 8.

[0064] In summary, the utility model provides an isolating switch that is convenient for observing the opening and closing status. An opening and closing indication device is installed on the switch body, which is specifically composed of a transmission component and an opening and closing indication component. During the opening and closing process, the knife handle of the switch body drives the swinging member to move through the transmission component when it swings, so that the swinging member points to the opening mark or the closing mark respectively. When the operator cannot see clearly whether the knife handle is in place, the direction of the swinging member can be conveniently observed to determine whether the opening and closing is in place, thereby ensuring the safe operation of the live equipment.
