[0003] However, in the prior art, there are still many problems with circuit safety, and operators are still prone to the risk of electric shock, which threatens the safety of the operators. Utility Model Content

[0004] The technical problem solved by the utility model is the low safety of circuits in the prior art.

[0005] The embodiment of the present utility model can be implemented as follows:

[0006] The utility model provides an operating hole shielding structure, which is applied to an isolating switch mechanism. The isolating switch mechanism has a first operating shaft and an output shaft connected to the first operating shaft in a transmission manner. The output shaft is used to perform closing, opening, and grounding. The operating hole shielding structure includes:

[0007] a shielding plate rotatably disposed on the top of the output shaft and capable of freely rotating relative to the output shaft;

[0009] The advantages of the operating hole shielding structure provided by the utility model over the prior art include:

[0010] When this operating hole shielding structure is applied to an isolating switch mechanism, because the linkage assembly is connected to the circuit breaker, and when the circuit breaker is closed, the linkage assembly drives the shielding plate to rotate to shield the first operating shaft through the shielding plate, the operating hole corresponding to the first operating shaft on the isolating switch mechanism can be shielded. This can prevent the operator from inserting the operating mechanism to operate the first operating shaft when the circuit breaker is closed. This can prevent the operator from operating the isolating switch mechanism when the circuit breaker is closed, thus preventing the user from electric shock. On the one hand, it can play a foolproof role, and on the other hand, it can also improve circuit safety. Based on this, the operating hole shielding structure can improve the problem of low circuit safety in the existing technology.

[0011] Optionally, the isolating switch mechanism also includes a second operating shaft, which is transmission-connected to the output shaft and spaced apart from the first operating shaft; when the circuit breaker is closed, the linkage assembly drives the baffle to rotate above the second operating shaft to block the second operating shaft, and when the circuit breaker is open, drives the baffle to rotate to stagger away from the second operating shaft to avoid the second operating shaft.

[0012] Optionally, the shielding plate includes a rotating connection part, a first shielding part and a second shielding part; the first shielding part and the second shielding part are both connected to the rotating connection part, the first shielding part is used to shield the first operating shaft when the circuit breaker is closed, and the second shielding part is used to shield the second operating shaft when the circuit breaker is closed.

[0013] Optionally, the first shielding portion extends along a first straight line, the second shielding portion extends along a second straight line, and the first straight line and the second straight line are arranged at an angle.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0029] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0031] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, an isolating switch mechanism 10 is provided. The isolating switch mechanism 10 can be applied to an isolating switch, and the isolating switch can be applied to a circuit, and the isolating switch mechanism 10 can operate the isolating switch to perform closing, opening and grounding; wherein, when closing is performed, the circuit is in a conducting state; when opening is performed, the circuit is in a disconnected state; when grounding is performed, the circuit is in a grounded state.

[0032] In this embodiment, the disconnector mechanism 10 includes a first operating shaft 12, a second operating shaft 13, and an output shaft 11. The first operating shaft 12 and the second operating shaft 13 are both in transmission connection with the output shaft 11. When the first operating shaft 12 rotates, it can drive the output shaft 11 to rotate and enable the output shaft 11 to perform the functions of closing or opening the switch. When the second operating shaft 13 rotates, it can drive the output shaft 11 to rotate and enable the output shaft 11 to perform the functions of grounding or opening the switch. It should be understood that in other embodiments of the present application, the second operating shaft 13 can also be omitted, and the functions of closing, opening, and grounding can be achieved only by the driving effect of the first operating shaft 12 on the output shaft 11.

[0033] It should be noted that in the isolating switch mechanism 10, the first operating shaft 12 and the second operating shaft 13 are both located inside the isolating switch mechanism 10, and an operating hole is provided on the isolating switch mechanism 10 for the operating mechanism to pass through. When the operating mechanism passes through the operating hole, it can cooperate with the first operating shaft 12 or the second operating shaft 13 to drive the first operating shaft 12 and the second operating shaft 13 by applying force to the operating mechanism. The first operating shaft 12 and the second operating shaft 13 are provided with operating holes in a one-to-one correspondence.

[0034] In order to improve the problem of low circuit safety in the prior art, an operation hole shielding structure 20 is also provided in this embodiment. The operation hole shielding structure 20 is applied to the above-mentioned isolating switch mechanism 10, so that the isolating switch mechanism 10 provided in this embodiment can also improve the problem of low circuit safety in the prior art.

[0035] In this embodiment, the operating hole shielding structure 20 includes a shielding plate 100 and a linkage assembly 200. The shielding plate 100 is rotatably disposed on top of the output shaft 11 and can rotate freely relative to the output shaft 11. The linkage assembly 200 is connected to the shielding plate 100 and is used to connect to the circuit breaker; the linkage assembly 200 is used to be pulled when the circuit breaker is closed and opened, and when the circuit breaker is closed, it drives the shielding plate 100 to rotate above the first operating shaft 12 to block the first operating shaft 12, and when the circuit breaker is opened, it drives the shielding plate 100 to rotate away from the first operating shaft 12 to avoid the first operating shaft 12.

[0036] That is, the linkage assembly 200 can change the state of the baffle 100 based on the action of the circuit breaker, so as to open the operating hole corresponding to the first operating shaft 12 when the circuit breaker is opened, and block the operating hole corresponding to the first operating shaft 12 when the circuit breaker is closed.

[0037] As described above, when the operation hole shielding structure 20 is applied to the disconnector mechanism 10, since the linkage assembly 200 is connected to the circuit breaker, and when the circuit breaker is closed, the linkage assembly 200 drives the shielding plate 100 to rotate to shield the first operating shaft 12 through the shielding plate 100, the operation hole corresponding to the first operating shaft 12 on the disconnector mechanism 10 can be shielded, thereby preventing the operator from inserting the operating mechanism to operate the first operating shaft 12 when the circuit breaker is closed. This can prevent the operator from operating the disconnector mechanism 10 when the circuit breaker is closed, thereby preventing the user from being electrocuted. On the one hand, it can play a role in preventing mistakes, and on the other hand, it can also improve circuit safety. Based on this, the operation hole shielding structure 20 can improve the problem of low circuit safety in the prior art.

[0038] Furthermore, when the disconnector mechanism 10 also includes a second operating shaft 13, when the circuit breaker is closed, the linkage assembly 200 drives the baffle 100 to rotate above the second operating shaft 13 to block the second operating shaft 13, and when the circuit breaker is opened, it drives the baffle 100 to rotate to offset the second operating shaft 13 to avoid the second operating shaft 13.

[0039] In other words, the shielding plate 100 can simultaneously block the two operating holes corresponding to the first operating shaft 12 and the second operating shaft 13 when the circuit breaker is closed, so that the operator cannot insert the operating mechanism into the operating hole to operate the first operating shaft 12 and the second operating shaft 13, thereby avoiding the risk of electric shock to the operator and playing a fool-proof role; at the same time, it also further improves the safety of the circuit.

[0040] In this embodiment, the shielding plate 100 includes a rotating connection portion 110, a first shielding portion 120, and a second shielding portion 130. The first shielding portion 120 and the second shielding portion 130 are both connected to the rotating connection portion 110. The first shielding portion 120 is used to shield the first operating shaft 12 when the circuit breaker is closed, and the second shielding portion 130 is used to shield the second operating shaft 13 when the circuit breaker is closed. By providing separate portions of the shielding plate 100 for shielding the first operating shaft 12 and the second operating shaft 13, redundant structures can be omitted. This can prevent the isolating switch mechanism 10 from becoming overly complex. On the other hand, it can also reduce the area of ​​the shielding plate 100, thereby reducing the area of ​​the isolating switch mechanism 10 shielded by the shielding plate 100, thereby facilitating the inspection and maintenance of the isolating switch mechanism 10.

[0041] Furthermore, in order to facilitate the first shielding portion 120 and the second shielding portion 130 to synchronously shield the two operating holes, in this embodiment, the first shielding portion 120 extends along a first straight line, and the second shielding portion 130 extends along a second straight line, and the first straight line and the second straight line are arranged at an angle. Figure 1 For example, it can be seen that the rotation connection portion 110 is the intersection of the first blocking portion 120 and the second blocking portion 130, and the first blocking portion 120, the second blocking portion 130 and the rotation connection portion 110 together form a V shape.

[0042] It should be understood that in other embodiments of the present application, the configuration of the first shielding portion 120 and the second shielding portion 130 may also be adjusted according to actual circumstances. For example, to facilitate the first shielding portion 120 or the second shielding portion 130 to avoid components in the disconnector mechanism 10, the first shielding portion 120 or the second shielding portion 130 may be configured to extend along an arc path.

[0043] In this embodiment, the rotating connection portion 110, the first shielding portion 120, and the second shielding portion 130 are integrally formed. This integrated molding process reduces manufacturing difficulty and, consequently, manufacturing costs. The rotating connection portion 110, the first shielding portion 120, and the second shielding portion 130 can be formed by cutting or casting.

[0044] Of course, in other embodiments, the first shielding portion 120 and the second shielding portion 130 may also be fixed to the rotating connection portion 110 in other ways, such as welding, bonding, or screw connection.

[0045] In this embodiment, the rotating connection portion 110, the first shielding portion 120, and the second shielding portion 130 are all sheet-shaped and located in the same plane. This can reduce the space occupied by the shielding plate 100 in the disconnector mechanism 10, thereby facilitating miniaturization of the disconnector mechanism 10.

[0046] In addition, in this embodiment, the shielding plate 100 further includes a connecting portion 140, which includes an extension section 141 and a connecting section 142. The extension section 141 is connected to the rotating connecting portion 110 and extends along a straight line at an angle to the plane of the rotating connecting portion 110. The connecting section 142 is provided at the end of the extension section 141 away from the rotating connecting portion 110, and the linkage assembly 200 is connected to the connecting section 142. By extending the connecting section 142 by the extension section 141 to a position where it is not coplanar with the first shielding portion 120 and the second shielding portion 130, interference between the linkage assembly 200 and the first shielding portion 120 or the second shielding portion 130 during rotation of the shielding plate 100 can be avoided, thereby preventing damage to the shielding plate 100 and causing failure.

[0047] Preferably, the extension section 141 is perpendicular to the rotating connection portion 110, and the connection section 142 is arranged parallel to the rotating connection portion 110. This can reduce the overall space occupied by the shielding plate 100 and reduce the difficulty of manufacturing the connection portion 140, thereby reducing costs.

[0048] Furthermore, the connecting portion 140 and the rotating connecting portion 110 are integrally formed, so that the shielding plate 100 is integrally formed, which can reduce the manufacturing difficulty and cost.

[0049] In summary, in the operation hole shielding structure 20 and the disconnector mechanism 10 provided in this embodiment, since the linkage assembly 200 is connected to the circuit breaker, and when the circuit breaker is closed, the linkage assembly 200 drives the shielding plate 100 to rotate so as to shield the first operating shaft 12 through the shielding plate 100, thereby shielding the operation hole corresponding to the first operating shaft 12 on the disconnector mechanism 10, thereby preventing the operator from inserting the operating mechanism to operate the first operating shaft 12 when the circuit breaker is closed, thereby preventing the operator from operating the disconnector mechanism 10 when the circuit breaker is closed, thereby preventing the user from being electrocuted. On the one hand, it can play a role in preventing mistakes, and on the other hand, it can also improve circuit safety. Based on this, the operation hole shielding structure 20 can improve the problem of low circuit safety in the prior art. Furthermore, when the disconnector mechanism 10 has a second operating shaft 13, the shielding plate 100 can simultaneously block the two operating holes corresponding to the first operating shaft 12 and the second operating shaft 13 when the circuit breaker is closed, so that the operator cannot insert the operating mechanism into the operating hole to operate the first operating shaft 12 and the second operating shaft 13, thereby avoiding the risk of electric shock to the operator and playing a fool-proof role; at the same time, it also further improves the safety of the circuit.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
