[0034] like Figure 1-4 As shown, the utility model provides an isolating switch handle, including a mounting seat 100 , a handle body 200 , a limiting pin 300 , a first elastic member 400 and a locking pin 500 .
[0035] A limiting hole 110 is provided on one side of the mounting seat 100 facing the handle body 200. The connection end of the handle body 200 is rotatably connected to the mounting seat 100, and the operating end is freely extended. When in use, the mounting seat 100 is installed at a preset position, and a connecting rod is installed in the mounting hole 210 of the connection end of the handle body 200, and the handle body 200 is connected to the isolating switch body through the connecting rod, so that the isolating switch body can be operated by rotating the handle body 200.
[0036] The limit pin 300 is slidably installed at the connecting end of the handle body 200, and the limit pin 300 can make reciprocating linear motion between a first position and a second position in a direction close to or away from the mounting seat 100, wherein when the limit pin 300 is in the first position, the end of the limit pin 300 facing the limit hole 110 is inserted into the limit hole 110 to achieve the purpose of limiting the handle body 200, and when the limit pin 300 is in the second position, the end of the limit pin 300 facing the limit hole 110 is separated from the limit hole 110 to achieve the purpose of rotating the handle body 200.
[0037] The two ends of the first elastic member 400 are respectively connected to the handle body 200 and the limiting pin 300, and in a natural state, the first elastic member 400 has a tendency to move the limiting pin 300 toward the limiting hole 110. Preferably, the first elastic member 400 is a spring.
[0038] The first end of the locking pin 500 is slidably connected to the handle body 200, and the second end extends outside the handle body 200. The locking pin 500 can make reciprocating linear motion between the third position and the fourth position in the direction close to or away from the limit pin 300, wherein when the locking pin 500 is in the third position, the first end of the locking pin 500 abuts against the end of the limit pin 300 away from the limit hole 110, so that the limit pin 300 cannot move from the first position to the second position; when the locking pin 500 is in the fourth position, the first end of the locking pin 500 is separated from the end of the limit pin 300 away from the limit hole 110, so that the limit pin 300 only needs to overcome the elastic force of the first elastic member 400 to move from the first position to the second position, and the second end of the locking pin 500 is provided with a first locking portion 510, and the handle body 200 is provided with a second locking portion 220, and the first locking portion 510 and the second locking portion 220 are both provided with locking holes. When in use, the locking pin 500 is placed in the third position so that the locking holes on the first locking portion 510 and the second locking portion 220 correspond to each other, and a padlock is inserted into the locking hole to prevent the limit pin 300 from moving, thereby preventing the handle body 200 from rotating.
[0039] When the locking pin 500 is in the fourth position and the external force acting on the handle body 200 exceeds a preset value, the limiting pin 300 can move from the first position to the second position. Specifically, the middle cross-section of the limiting hole 110 is one of a hemispherical shape, a triangle, or a trapezoid, so that when the locking pin 500 is in the fourth position, the handle body 200 is rotated with force, and under the action of the external force, the limiting pin 300 can overcome the elastic force of the first elastic member 400 and move from the first position to the second position.
[0040] Specifically, during use, when the handle body 200 needs to be operated, the padlock is removed, the locking pin 500 is placed in the fourth position, and then the handle body 200 is rotated. When the external force applied to the handle body 200 exceeds the preset value, the limit pin 300 moves from the first position to the second position and finally moves to the second position, thereby achieving the purpose of rotating the handle body 200.
[0041] When the handle body 200 needs to be locked, the limit pin 300 is placed in the first position, and the locking pin 500 is placed in the third position, so that the lock holes on the first locking portion 510 and the second locking portion 220 correspond to each other, and a padlock is inserted into the lock hole to lock the locking pin 500. At this time, since the first end of the locking pin 500 corresponds to the end of the limit pin 300 away from the limit hole 110, the limit pin 300 cannot move from the first position to the second position, so that the handle body 200 can be locked.
[0042] In one embodiment, a second elastic member 600 is further included, and both ends of the second elastic member 600 are respectively connected to the locking pin 500 and the handle body 200, and in a natural state, the second elastic member 600 has a tendency to move the locking pin 500 away from the limiting pin 300.
[0043] The isolating switch handle provided in this embodiment is provided with a second elastic member 600. When the padlock is removed, the locking pin 500 can be driven from the third position to the fourth position under the action of the elastic force of the second elastic member 600. There is no need to manually move the locking pin 500 from the third position to the fourth position, and the operation is convenient.
[0044] Preferably, the second elastic member 600 is a spring.
[0045] In one embodiment, there are two limit holes 110. When the limit pin 300 is located in one of the two limit holes 110, it means that the limit switch is in a closed state, and when the limit pin 300 is located in the other limit hole 110, it means that the limit switch is in an open state.
[0046] The isolating switch handle provided in the present embodiment, during the process of opening the gate, rotates the handle body 200 so that the limit pin 300 is moved out of the current limit hole 110. When the handle body 200 is rotated to move the limit pin 300 to another limit hole 110, since it is necessary to apply a larger external force to the handle body 200 to move the limit pin 300 out of the limit hole 110, it is possible to determine whether the handle body 200 is rotated to the gate opening position. Similarly, during the process of closing the gate, rotates the handle body 200 so that the limit pin 300 is moved out of the current limit hole 110. When the handle body 200 is rotated to move the limit pin 300 to another limit hole 110, since it is necessary to apply a larger external force to the handle body 200 to move the limit pin 300 out of the limit hole 110, it is possible to determine whether the handle body 200 is rotated to the gate closing position, thereby achieving the purpose of avoiding damage to the limit switch due to excessive operation.
[0047] In one embodiment, a first indicating portion 230 is disposed on the handle body 200 , and a second indicating portion 120 matching the first indicating portion 230 is disposed on the mounting seat 100 . Two second indicating portions 120 are disposed, and the two second indicating portions 120 correspond to the two limiting holes 110 respectively.
[0048] The isolating switch handle provided in this embodiment is provided with a first indicating portion 230 and two second indicating portions 120. When the handle body 200 is in the opening position, the first indicating portion 230 corresponds to one of the two second indicating portions 120. When the handle body 200 is in the closing position, the first indicating portion 230 corresponds to the other of the two second indicating portions 120.
[0049] Preferably, the two second indicator portions 120 have different colors and / or shapes, so as to facilitate distinguishing whether the handle body 200 is in the gate opening position or the gate closing position.
[0050] In one embodiment, a third indicator 130 for indicating the rotation direction of the handle body 200 is also provided on the mounting seat 100, so as to facilitate the purpose of clarifying the rotation direction of the handle body 200, thereby achieving the purpose of damaging the isolating switch due to incorrect rotation of the handle body 200.
[0051] In one embodiment, an operating portion 520 is disposed at the second end of the locking pin 500 to facilitate the movement of the locking pin 500 .
[0052] In one embodiment, a universal ball 700 is further included. The universal ball 700 is arranged at one end of the limiting pin 300 facing the limiting hole 110 to achieve the purpose of reducing friction.
[0053] In one embodiment, the limiting hole 110 is adapted to the universal ball 700 .
[0054] The utility model also provides an isolating switch, comprising the isolating switch handle described in any of the above embodiments.
[0055] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
