Description

Technical Field

[0001] The present application relates to the technical field of power distribution devices, and in particular to a handle and a power distribution cabinet. Background Art

[0002] A power distribution cabinet usually includes a cabinet, a handle, and a power distribution device (e.g., a circuit breaker). The handle is arranged outside the cabinet, the power distribution device is arranged inside the cabinet, and the handle is connected to the power distribution device. When the handle is turned, the power distribution device can be controlled to open or close. When the power distribution device is opened, the power distribution cabinet is powered off. When the power distribution device is closed, the power distribution cabinet is powered on.

[0003] When the handle is connected to the power distribution equipment, specifically, the rotating shaft of the handle is connected to the power distribution equipment to control the opening or closing of the power distribution equipment.

[0004] However, in the process of rotating the shaft to control the power distribution equipment, the rotating shaft is prone to press against other core components of the handle in the opposite direction, causing damage to the core components. Utility Model Content

[0005] The embodiment of the present application provides a handle and a power distribution cabinet to solve the problem that the rotating shaft is prone to reversely press against other core components of the handle, thereby protecting the core components.

[0006] In a first aspect, an embodiment of the present application provides a handle. The handle is applied to a power distribution cabinet, which includes a cabinet body and a power distribution device arranged in the cabinet body. The handle is installed in the cabinet body. The handle includes a handle body, a driving member and a rotating shaft. The handle body can be rotated under force. The driving member is connected to the handle body to rotate with the handle body. The rotating shaft is installed on the driving member and connected to the power distribution device. The rotating shaft can rotate with the driving member to drive the power distribution device to open or close.

[0007] Considering the technical problem that the core component (handle body) of the existing handle is easily damaged by the reverse pressure of the rotating shaft. The embodiment of the present application sets the handle to include a handle body, a driving member and a rotating shaft, so that the handle body can drive the rotating shaft to rotate through the driving member, rather than directly driving the rotating shaft to rotate. In this way, the handle body will not directly contact the rotating shaft, the rotating shaft will not reversely press the handle body, and the handle body will not be damaged by the pressure of the rotating shaft.

[0008] In a possible design, the rotating shaft includes a shaft body and a connecting column, the connecting column is connected to the end of the shaft body, and the extending direction of the connecting column is perpendicular to the extending direction of the shaft body. The driving member includes a mounting hole adapted to both the shaft body and the connecting column, and the shaft body and the connecting column are both embedded in the mounting hole, so that the rotating shaft is mounted on the driving member.

[0009] Through the above solution, when the driving member rotates, the hole wall of the mounting hole can push against the shaft body and the connecting column to rotate the rotating shaft.

[0010] In a possible design, the handle body includes a connecting cavity, and a portion of the driving member is embedded in the connecting cavity so that the driving member is connected to the handle body.

[0011] Through the above solution, during the rotation of the handle body, the cavity wall of the connecting cavity can push the driving member to make the driving member rotate.

[0012] In a possible design, a first limiting structure is provided at the bottom of the connecting cavity, and a second limiting structure is provided on the driving member. The first limiting structure cooperates with the second limiting structure to limit the relative position of the driving member and the handle body.

[0013] Through the above solution, after the first limiting structure and the second limiting structure are assembled, when the handle body is rotated under force, the first limiting structure and the second limiting structure can limit each other to prevent the driving member and the handle body from rotating relative to each other. When the driving member and the handle body do not rotate relative to each other, the handle body can drive the rotating shaft to rotate by a set angle through the driving member.

[0014] In a possible design, the first limiting structure is configured as a groove, and the second limiting structure is configured as a protrusion adapted to the groove. Alternatively, the first limiting structure is configured as a protrusion, and the second limiting structure is configured as a groove adapted to the protrusion. The protrusion extends into the groove to limit the relative position of the driving member and the handle body.

[0015] Through the above solution, after the protrusion cooperates with the groove, when the handle body is rotated under force, the groove wall of the groove and the protrusion can limit each other to prevent the driving member and the handle body from rotating relative to each other.

[0016] In a possible design, the first limiting structure includes a first limiting hole; the second limiting structure includes a matching second limiting hole and a limiting screw, and the limiting screw is also matched with the first limiting hole. The limiting screw passes through the second limiting hole and is fixed to the first limiting hole to limit the relative position of the driving member and the handle body.

[0017] Through the above scheme, after the limit screw is fixed to the second limit hole and the first limit hole at the same time, when the handle body is rotated under force, the hole wall of the second limit hole of the driving member and the limit screw will limit each other, and the limit screw and the hole wall of the first limit hole at the bottom of the connecting cavity will limit each other to prevent the driving member and the handle body from rotating relative to each other.

[0018] In a possible design, the handle further includes a fixing seat, which is rotatably connected to the handle body and rotatably cooperates with the driving member.

[0019] Through the above solution, the handle body and the driving member can rotate relative to the fixed seat. In addition, when the handle body and the driving member rotate, the fixed seat can provide a fixed position for the handle body and the driving member to ensure that the positions of the rotation center of the handle body and the rotation center of the driving member are constant. Furthermore, when the driving member drives the rotating shaft to rotate, the rotation center of the rotating shaft can be kept constant, so that the rotating shaft can smoothly drive the power distribution equipment to open or close.

[0020] In a possible design, the fixing seat is provided with a through hole, the side of the driving member facing the handle body passes through the through hole and is connected to the handle body, and the side of the driving member facing away from the handle body abuts against the surface of the fixing seat facing away from the handle body.

[0021] Through the above solution, part of the fixing seat is clamped between the side of the driver facing the handle body and the side facing away from the handle body, so that the handle body, the fixing seat and the driver are installed together. Based on this, when the handle body and the driver rotate, the perforated hole wall can limit the driver in the direction perpendicular to the rotation center axis of the driver to prevent the driver from deviating. Furthermore, on the basis that the driver will not deviate, the rotation center of the driver will not deviate, and the rotation center of the handle body will not deviate.

[0022] In a possible design, the material of the driving member includes at least one of zinc, aluminum, copper or magnesium.

[0023] According to the above solution, during the process of the driving member driving the rotating shaft to rotate, since the driving member including at least one of zinc, aluminum, copper or magnesium has a relatively large overall strength, even if the rotating shaft presses against the driving member for a long time and multiple times, the driving member will not be damaged. Furthermore, on the basis that the driving member will not be damaged, the handle body will not be pressed by the rotating shaft, and the handle body will not be damaged by the pressing of the rotating shaft.

[0024] In a second aspect, the present application also provides a power distribution cabinet. The power distribution cabinet includes a cabinet, the handle of the first aspect, and a power distribution device. The handle is installed in the cabinet, the power distribution device is located in the cabinet, and the rotating shaft of the handle is connected to the power distribution device.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover non-exclusive inclusions.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the present application. For example, in the description of the present application, the directions or positional relationships indicated by the terms "bottom", "inside", "outside", "axial", "radial", "circumferential", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0041] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] The power distribution cabinet includes a cabinet body, a handle and a power distribution device. The handle is installed on the cabinet body, specifically, it can be installed on the cabinet door of the cabinet body, and the handle can be located outside the cabinet body. The power distribution device is arranged inside the cabinet body. The handle includes a handle body and a rotating shaft connected to each other. The handle body is used to rotate under force. The rotating shaft is connected to the power distribution device. The rotating shaft is used to rotate with the handle body and drive and control the power distribution device to open or close.

[0044] When the handle body is connected to the rotating shaft, a receiving cavity adapted to the rotating shaft is usually provided in the handle body, and part of the rotating shaft is installed in the receiving cavity. In this way, when the handle body rotates, the cavity wall of the receiving cavity can push against the rotating shaft, so that the rotating shaft rotates with the handle body.

[0045] However, when the cavity wall of the accommodating cavity causes the rotating shaft to rotate along with the handle body, the rotating shaft will press against the cavity wall of the accommodating cavity in the reverse direction, causing damage to the handle body.

[0046] Based on this, an embodiment of the present application provides a handle, which is configured to include a handle body, a driving member and a rotating shaft, so that the handle body can drive the rotating shaft to rotate through the driving member instead of directly driving the rotating shaft to rotate, so as to avoid the rotating shaft from pressing the handle body in the opposite direction.

[0047] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] The embodiment of the present application provides a handle. The handle is applied to a power distribution cabinet, which includes a cabinet body and a power distribution device arranged in the cabinet body. The handle is installed in the cabinet body. The power distribution device may be a circuit breaker or an isolating switch, etc., which is not specifically limited in the present application.

[0049] See also Figure 1 and Figure 2The handle 1 includes a handle body 11, a driving member 12 and a rotating shaft 13. The handle body 11 can be rotated under force. The driving member 12 is connected to the handle body 11 to rotate with the handle body 11. The rotating shaft 13 is installed on the driving member 12 and connected to the power distribution equipment. The rotating shaft 13 can rotate with the driving member 12 to drive the power distribution equipment to open or close.

[0050] In this embodiment, when the handle body 11 is rotated by force, the driving member 12 can rotate with the handle body 11; when the driving member 12 rotates with the handle body 11, the rotating shaft 13 can rotate with the driving member 12; during the rotation of the rotating shaft 13, the power distribution equipment can be driven to open or close. In other words, the handle body 11 can drive the rotating shaft 13 to rotate through the driving member 12, rather than directly driving the rotating shaft 13 to rotate. In this way, the handle body 11 will not directly contact the rotating shaft 13, the rotating shaft 13 will not press the handle body 11 in the opposite direction, and the handle body 11 will not be damaged by the pressing of the rotating shaft 13.

[0051] It should be noted that, in the handle of the prior art, the handle body 11 is directly connected to the rotating shaft 13, that is, the handle body 11 is the direct power source of the rotating shaft 13. In addition, the handle body 11 also needs to be installed with other components. However, the driving member 12 may not be there. Therefore, relative to the driving member 12, the handle body 11 is more important. Based on this, in the present embodiment, the driving member 12 is directly connected to the rotating shaft 13 so that the driving member 12 is the direct power source of the rotating shaft 13. In this way, the driving member 12 can accept the pressure of the rotating shaft 13 instead of the handle body 11. In other words, while the driving member 12 drives the rotating shaft 13, the driving member 12 replaces the handle body 11 to bear the pressure of the rotating shaft 13, so that the protection of the handle body 11 can be achieved.

[0052] Among them, see Figure 2 The handle body 11 may include a force-bearing handle and a rotating part connected to each other. The force-bearing handle is used to bear force. The rotating part is used to rotate based on the force of the force-bearing handle. The force-bearing handle may be a rod-shaped structure on the right side. The rotating part may be set as a roughly cylindrical structure on the left side.

[0053] The driving member 12 may be configured as a substantially cylindrical structure. One end of the driving member 12 may be connected to the rotating portion of the handle body 11 to rotate with the rotating portion.

[0054] The rotating shaft 13 can be configured to be substantially in the shape of a quadrangular prism. One end of the rotating shaft 13 is fixedly mounted on the driving member 12 so as to rotate with the driving member 12 .

[0055] In some embodiments, please combine Figure 3 and Figure 4The rotating shaft 13 includes a shaft body 131 and a connecting column 132. The connecting column 132 is connected to the end of the shaft body 131, and the extending direction of the connecting column 132 is perpendicular to the extending direction of the shaft body 131. The driving member 12 includes a mounting hole K adapted to both the shaft body 131 and the connecting column 132. Both the shaft body 131 and the connecting column 132 are embedded in the mounting hole K, so that the rotating shaft 13 is mounted on the driving member 12.

[0056] In this embodiment, when the driving member 12 rotates, the hole wall of the mounting hole K can push the shaft body 131 and the connecting column 132 to rotate the rotating shaft 13.

[0057] Among them, see Figure 3 , the shaft body 131 can be set as a quadrangular prism structure. The connecting column 132 can be set as a cylindrical structure. The connecting column 132 can be connected to any end of the shaft body 131. When specifically connected, for example, a through hole can be set at one end of the shaft body 131, and the connecting column 132 can be inserted into the through hole, and both ends of the connecting column 132 are exposed from the shaft body 131. Alternatively, the connecting column 132 can be integrally formed with the shaft body 131. The embodiments of the present application do not specifically limit this.

[0058] When the extension direction of the connecting column 132 is perpendicular to the extension direction of the shaft body 131, the shape of the rotating shaft 13 is relatively regular. In this way, it is not only easy to design and process the rotating shaft 13, but also easy to design and process the driving member 12, and it is also easy to install the rotating shaft 13 and the driving member 12.

[0059] See also Figure 4 , in the extension direction of the shaft body 131, the mounting hole K can penetrate the driving member 12. When the shaft body 131 and the connecting column 132 are both embedded in the mounting hole K, the outer walls of the shaft body 131 and the connecting column 132 can both abut against the hole wall of the mounting hole K. In this way, at the beginning moment when the driving member 12 rotates with the handle body 11, the driving member 12 can push the shaft body 131 and the connecting column 132 through the hole wall of the mounting hole K to rotate the rotating shaft 13, which is beneficial to improve the driving efficiency of the driving member 12 on the rotating shaft 13. Furthermore, when the outer walls of the shaft body 131 and the connecting column 132 abut against the hole wall of the mounting hole K, the rotating shaft 13 is not easy to be separated from the driving member 12, which is beneficial to improve the reliability of the installation of the rotating shaft 13 and the driving member 12.

[0060] In some embodiments, please combine Figure 4 and Figure 5 The handle body 11 includes a connecting cavity Q, and a portion of the driving member 12 is embedded in the connecting cavity Q so that the driving member 12 is connected to the handle body 11.

[0061] In this embodiment, during the rotation of the handle body 11 , the cavity wall of the connecting cavity Q can push the driving member 12 to make the driving member 12 rotate.

[0062] The connection cavity Q can be configured as a cylindrical cavity, a prismatic cavity or a Figure 5 The special-shaped cavity shown in the figure is not particularly limited in the embodiments of the present application.

[0063] When part of the driving member 12 is embedded in the connection cavity Q, specifically, the outer wall of the driving member 12 can abut against the cavity wall of the connection cavity Q. In this way, at the beginning of the rotation of the handle body 11, the handle body 11 can push the driving member 12 through the cavity wall of the connection cavity Q to rotate the driving member 12, which is beneficial to improve the driving efficiency of the driving member 12 on the rotating shaft 13. In addition, when the outer wall of the driving member 12 abuts against the cavity wall of the connection cavity Q, the driving member 12 is not easy to be separated from the handle body 11, which is beneficial to improve the reliability of the connection between the driving member 12 and the handle body 11.

[0064] In some embodiments, please combine Figure 4 and Figure 5 The first limiting structure XW1 is provided at the bottom of the connection cavity Q. The second limiting structure XW2 is provided on the driving member 12. The first limiting structure XW1 cooperates with the second limiting structure XW2 to limit the relative position of the driving member 12 and the handle body 11.

[0065] When the wall of the connection cavity Q pushes the driving member 12, the driving member 12 may rotate in the connection cavity Q. In other words, the driving member 12 rotates relative to the handle body 11. In this way, the angle at which the rotating shaft 13 rotates with the handle body 11 may be greater or less than the angle at which the handle body 11 rotates, resulting in the rotating shaft 13 being unable to rotate to the set angle and being unable to drive the power distribution equipment to open or close smoothly.

[0066] Based on this, in this embodiment, by setting the first limiting structure XW1 at the bottom of the connecting cavity Q and setting the second limiting structure XW2 at the driving member 12, after the first limiting structure XW1 and the second limiting structure XW2 are assembled, when the handle body 11 is rotated under force, the first limiting structure XW1 and the second limiting structure XW2 can limit each other to prevent the driving member 12 and the handle body 11 from rotating relative to each other. In the case where the driving member 12 does not rotate relative to the handle body 11, the handle body 11 can drive the rotating shaft 13 to rotate by a set angle through the driving member 12.

[0067] The cavity bottom of the connecting cavity Q may refer to a wall of the connecting cavity Q that is opposite to the cavity opening.

[0068] In the above embodiment, the first limiting structure XW1 and the second limiting structure XW2 can be set to various structural forms, and for ease of understanding, exemplary descriptions are given below.

[0069] In some embodiments, please combine Figure 4 and Figure 5, the first limiting structure XW1 is configured as a groove AC, and the second limiting structure XW2 is configured as a protrusion TQ adapted to the groove AC. Alternatively, the first limiting structure XW1 is configured as a protrusion TQ, and the second limiting structure XW2 is configured as a groove AC adapted to the protrusion TQ (not shown in the figure). The protrusion TQ extends into the groove AC to limit the relative position of the driving member 12 and the handle body 11.

[0070] In this embodiment, when the first limiting structure XW1 is configured as a groove AC, and the second limiting structure XW2 is configured as a protrusion TQ adapted to the groove AC, the protrusion TQ of the driving member 12 can extend into the groove AC of the cavity bottom of the connecting cavity Q. In this way, when the handle body 11 is rotated under force, the groove wall of the groove AC of the cavity bottom of the connecting cavity Q and the protrusion TQ of the driving member 12 will abut against each other and limit, so as to prevent the driving member 12 and the handle body 11 from rotating relative to each other.

[0071] Alternatively, when the first limiting structure XW1 is configured as a protrusion TQ and the second limiting structure XW2 is configured as a groove AC that matches the protrusion TQ, the protrusion TQ at the bottom of the connecting cavity Q can be embedded in the groove AC on the driving member 12. In this way, when the handle body 11 rotates, the groove wall of the groove AC of the driving member 12 and the protrusion TQ at the bottom of the connecting cavity Q will abut against each other and limit, so as to prevent the handle body 11 and the driving member 12 from rotating relative to each other.

[0072] The shape of the groove AC may correspond to the shape of the protrusion TQ. For example, when the protrusion TQ is set to a prism shape, the groove AC may be set to a prism-shaped groove. Alternatively, when the protrusion TQ is set to a cylindrical shape, the groove AC may be set to a cylindrical groove. The embodiment of the present application does not specifically limit the shape of the groove AC and the shape of the protrusion TQ.

[0073] In other embodiments, please combine Figure 4 and Figure 5 The first limiting structure XW1 includes a first limiting hole K1. The second limiting structure XW2 includes a second limiting hole K2 and a limiting screw LD that matches the first limiting hole K1. The limiting screw LD passes through the second limiting hole K2 and is fixed to the first limiting hole K1 to limit the relative position of the driving member 12 and the handle body 11.

[0074] In this embodiment, after the limit screw LD is fixed to the second limit hole K2 and the first limit hole K1 at the same time, when the handle body 11 is rotated under force, the hole wall of the second limit hole K2 of the driving member 12 and the limit screw LD will limit each other, and the limit screw LD and the hole wall of the first limit hole K1 at the bottom of the connecting cavity Q will limit each other to prevent the driving member 12 and the handle body 11 from rotating relative to each other.

[0075] The first limiting hole K1 and the second limiting hole K2 may both be threaded holes. Alternatively, the first limiting hole K1 may be a light hole with a smooth inner wall, and the second limiting hole K2 may be a threaded hole. This embodiment of the present application does not limit this.

[0076] In some other embodiments, please combine Figure 4 and Figure 5 , the first limiting structure XW1 includes the protrusion TQ of some of the aforementioned embodiments, and the first limiting hole K1 of other of the aforementioned embodiments. Correspondingly, the second limiting structure XW2 includes the groove AC of some of the aforementioned embodiments, and the second limiting hole K2 and the limiting screw LD of other of the aforementioned embodiments. The protrusion TQ extends into the groove AC, and the limiting screw LD passes through the second limiting hole K2 and is fixed to the first limiting hole K1 to limit the relative position of the driving member 12 and the handle body 11.

[0077] In this embodiment, the protrusion TQ extends into the groove AC to limit the driving member 12 and the handle body 11 in the same manner as in some of the aforementioned embodiments, which will not be described in detail here. In addition, the limiting screw LD passes through the second limiting hole K2 and is fixed to the first limiting hole K1 to limit the driving member 12 and the handle body 11 in the same manner as in some of the aforementioned embodiments, which will not be described in detail here.

[0078] The shapes of the groove AC and the protrusion TQ are the same as those of some of the aforementioned embodiments. The shapes of the first limiting hole K1 and the second limiting hole K2 are the same as those of some of the aforementioned other embodiments. They will not be described in detail here.

[0079] In some embodiments, see Figure 6 The handle 1 further includes a fixing seat 14 , which is rotatably connected to the handle body 11 and rotatably matched with the driving member 12 .

[0080] In this embodiment, the handle body 11 and the driving member 12 can rotate relative to the fixed seat 14. In addition, when the handle body 11 and the driving member 12 rotate, the fixed seat 14 can provide a fixed position for the handle body 11 and the driving member 12 to ensure that the positions of the rotation center of the handle body 11 and the rotation center of the driving member 12 are constant. Furthermore, when the driving member 12 drives the rotating shaft 13 to rotate, the rotation center of the rotating shaft 13 can be ensured to be constant, so that the rotating shaft 13 can smoothly drive the power distribution equipment to open or close.

[0081] When the fixing seat 14 is rotatably connected to the handle body 11, for example, an annular groove may be provided on the inner wall of the fixing seat 14, and an annular convex ring adapted to the annular groove may be provided on the outer wall of the handle body 11. Alternatively, an annular convex ring may be provided on the inner wall of the fixing seat 14, and an annular groove adapted to the annular convex ring may be provided on the outer wall of the handle body 11. The annular convex ring may be embedded in the annular groove and rotate in the annular groove.

[0082] In addition, when the fixing seat 14 and the driving member 12 are rotationally matched, for example, the fixing seat 14 can be provided with a through hole CK, and the driving member 12 can be sleeved in the through hole CK and rotated in the through hole CK to rotate with the fixing seat 14.

[0083] It is worth pointing out that the fixing base 14 of this embodiment can be fixed to the cabinet of the power distribution cabinet so that the handle 1 is installed on the cabinet. Exemplarily, the fixing base 14 can be fixed to the cabinet of the power distribution cabinet in a hole-shaft connection manner.

[0084] In some embodiments, please combine Figure 6 and Figure 7 When the fixing seat 14 is provided with a through hole CK, the side of the driving member 12 facing the handle body 11 passes through the through hole CK and is connected to the handle body 11 , and the side of the driving member 12 facing away from the handle body 11 abuts against the surface of the fixing seat 14 facing away from the handle body 11 .

[0085] In this embodiment, part of the fixing seat 14 is clamped between the side of the driver 12 facing the handle body 11 and the side facing away from the handle body 11, so that the handle body 11, the fixing seat 14 and the driver 12 are installed together. Based on this, when the handle body 11 and the driver 12 rotate, the hole wall of the perforation CK can limit the driver 12 in the direction perpendicular to the rotation center axis of the driver 12 to prevent the driver 12 from deviating. Furthermore, on the basis that the driver 12 will not deviate, the rotation center of the driver 12 will not deviate, and the rotation center of the handle body 11 will not deviate either.

[0086] In addition, when the side of the driving member 12 facing away from the handle body 11 abuts against the surface of the fixing seat 14 facing away from the handle body 11, the fixing seat 14 can also limit the driving member 12 in the extension direction of the rotation center axis of the driving member 12 to prevent the driving member 12 from escaping from the fixing seat 14, which is beneficial to improve the reliability of the installation of the driving member 12 and the handle body 11.

[0087] Please continue to see Figure 7 The shape of the fixing seat 14 can be set to be roughly truncated cone-shaped. The fixing seat 14 can be provided with an inner cavity to facilitate the arrangement of other components. The perforation CK can be provided in the middle part of the fixing seat 14. The perforation CK can be provided as a circular hole.

[0088] In addition, an annular protrusion may be provided on a side of the driving member 12 facing away from the handle body 11 , and the annular protrusion can abut against a surface of the fixing seat 14 facing away from the handle body 11 .

[0089] In the above embodiments, the materials of the handle body 11 and the rotating shaft 13 can both include insulating materials such as plastic. The driving member 12 can be made of a variety of materials. For ease of understanding, an exemplary description is given below.

[0090] In some embodiments, the material of the driving member 12 includes non-metal such as plastic.

[0091] In this embodiment, the driving member 12 made of plastic material can drive the rotating shaft 13 to rotate, so that the rotating shaft 13 drives the power distribution equipment to open or close.

[0092] In the process that the driving member 12 drives the rotating shaft 13 to rotate, if the rotating shaft 13 presses against the driving member 12 for a long time and multiple times, the driving member 12 may be damaged. However, when the driving member 12 is damaged, the driving member 12 may be replaced.

[0093] Furthermore, even if the driving member 12 needs to be replaced, compared with the handle body 11, since the driving member 12 does not need to install other components, the structure of the driving member 12 is simpler than that of the handle body 11. Therefore, the maintenance cost of the handle 1 is lower when replacing the driving member 12 than when replacing the handle body 11.

[0094] In other embodiments, the material of the driving member 12 includes at least one of zinc, aluminum, copper or magnesium.

[0095] In this embodiment, the driving member 12 including at least one of zinc, aluminum, copper or magnesium can drive the rotating shaft 13 to rotate, so that the rotating shaft 13 drives the power distribution equipment to open or close.

[0096] In the process of the driving member 12 including at least one of zinc, aluminum, copper or magnesium driving the rotating shaft 13 to rotate, since zinc, aluminum, copper or magnesium are all metals, the overall strength of the driving member 12 will be relatively large. Based on this, even if the rotating shaft 13 presses against the driving member 12 for a long time and many times, the driving member 12 will not be damaged. Further, on the basis that the driving member 12 will not be damaged, the handle body 11 will not be pressed by the rotating shaft 13, and the handle body 11 will not be damaged by the pressing of the rotating shaft 13.

[0097] In some embodiments, see Figure 8, the handle 1 also includes a forced unlocking assembly 15. The forced unlocking assembly 15 is accommodated in the inner cavity of the fixed seat 14. The forced unlocking assembly 15 includes a push plate 151, a push rod 152 and an elastic member 153. Among them, the push plate 151 is slidably arranged in the middle area of ​​the inner cavity. The push rod 152 is located on the first side of the push plate 151 and contacts the push plate 151. The push rod 152 is also arranged in a push rod hole arranged on the fixed seat 14. Among them, the push rod hole connects the inside of the fixed seat 14 with the outside. The elastic member 153 is located on the second side of the push plate 151 and abuts against the push plate 151. The elastic member 153 is also arranged in a fixing groove arranged on the fixed seat 14. Among them, the first side is opposite to the second side. The middle part of the push plate 151 is provided with a hole for the rotation shaft 13 to pass through. After the rotation shaft 13 passes through the hole of the push plate 151 and the perforation CK of the fixed seat 14 in sequence, it is installed in the mounting hole K of the driving member 12.

[0098] The forced unlocking assembly 15 is used to control the opening or closing of the cabinet door on the cabinet body when the switch is closed. Specifically, the opening or closing of the cabinet door is determined by whether the rotating shaft 13 can escape from the limiting hole of the push plate 151. For ease of understanding, the following is a detailed description.

[0099] The rotating shaft 13 passes through the hole of the push plate 151 and the through hole CK of the fixing member in sequence, and is installed in the installation hole K of the driving member 12 .

[0100] When the handle body 11 rotates to the position of closing the power distribution equipment, the rotating shaft 13 rotates with the handle body 11 until the connecting column 132 is abutted by the push plate 151. At this time, the rotating shaft 13 cannot escape from the limiting hole of the push plate 151, and the cabinet door of the cabinet cannot be opened.

[0101] It should be noted that when the door of the distribution cabinet cannot be opened, it can protect people outside the distribution cabinet.

[0102] When the distribution equipment fails during the closing process and cannot be opened (for example, the contacts of the distribution equipment are stuck and cannot be opened), the push plate 151 can be pushed by the push rod 152 to change the position of the push plate 151, and the limiting hole on the push plate 131 is aligned with the connecting column 132, so that the rotating shaft 13 can be disengaged from the limiting hole of the push plate 151, thereby facilitating the opening of the door of the distribution cabinet. In this process, the elastic member 153 is compressed to store energy.

[0103] It should be noted that when the door of the power distribution cabinet is opened, it is convenient for maintenance personnel to enter the power distribution cabinet to repair the power distribution equipment.

[0104] After the rotating shaft 13 escapes from the limiting hole of the push plate 151 , the elastic member 153 releases energy and applies force to the push plate 151 to restore the push plate 151 .

[0105] The structures of the push rod 152 and the push plate 151 may be the same as those in the prior art, and will not be described in detail herein.

[0106] The elastic member 153 may be a straight spring, a torsion spring, or a U-shaped spring sheet, etc., and the present embodiment of the application does not specifically limit this. Based on the different forms of the elastic member 153, the setting position and setting method of the elastic member 153 on the fixing seat 14 are also different. The setting form of the straight spring, torsion spring, or U-shaped spring sheet can be the same as the existing conventional setting form, which will not be repeated here.

[0107] In some embodiments, see Figure 8 The handle 1 also includes a positioning assembly 16, which includes a padlock bracket 161, a positioning column 162 and a reset spring 163. Among them, the padlock bracket 161 is rotatably connected to the handle body 11. Specifically, the handle body 11 is provided with a cavity for accommodating the padlock bracket 161, and the padlock bracket 161 can be accommodated in the cavity, and a rotating column is provided in the middle part of the padlock bracket 161, and the padlock bracket 161 is rotatably connected to the cavity wall of the cavity through the rotating column. The first end of the padlock bracket 161 is connected to the positioning column 162. The reset spring 163 is sleeved on the positioning column 162. A positioning hole is provided on the fixed seat 14 at a position opposite to the positioning column 162. A lock hole is provided at the second end of the padlock bracket 161. The lock hole can be hidden in the handle body 11, or exposed from the handle body 11.

[0108] In this embodiment, when the power distribution equipment is not faulty, the lock hole at the second end of the padlock bracket 161 is hidden in the handle body 11, and the positioning column 162 at the first end of the padlock bracket 161 does not extend into the positioning hole of the fixing seat 14. The handle body 11 can be rotated relative to the fixing seat 14 under force to control the power distribution equipment to open or close through the driving member 12 and the rotating shaft 13. In this state, the reset spring 163 is in a normal state.

[0109] When the power distribution equipment fails and needs to be repaired, in the off state of the power distribution equipment, the lock hole at the second end of the control padlock bracket 161 is exposed to the handle body 11, and a padlock is installed at the lock hole, so that the positioning column 162 at the first end of the padlock bracket 161 extends into the positioning hole of the fixing seat 14 to limit the handle body 11. In this way, it can be prevented that others turn the handle body 11 to close the power distribution equipment, which is conducive to ensuring the safety of maintenance personnel during maintenance. In this process, the reset spring 163 is in a compressed energy storage state.

[0110] When the power distribution equipment is repaired, the padlock at the lock hole is removed, and the reset spring 163 releases energy and pushes the first end of the padlock bracket 161, so that the positioning column 162 at the first end of the padlock bracket 161 is disengaged from the positioning hole, thereby releasing the limit on the handle body 11. At the same time, the lock hole at the second end of the padlock bracket 161 is hidden in the handle body 11.

[0111] Among them, the structures of the padlock bracket 161, the positioning column 162 and the reset spring 163 can all be the same as the prior art, which will not be repeated here. In addition, the connection method of the padlock bracket 161 and the positioning column 162 is also the same as the prior art, which will not be repeated here.

[0112] The embodiment of the present application also provides a power distribution cabinet. The power distribution cabinet includes a cabinet, the aforementioned handle 1 and a power distribution device. The handle 1 is installed in the cabinet, the power distribution device is located in the cabinet, and the rotating shaft 13 of the handle 1 is connected to the power distribution device.

[0113] On the basis that the handle body 11 in the aforementioned handle 1 is not easily damaged, the handle 1 of the power distribution cabinet of this embodiment is also not easily damaged.

[0114] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application 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 make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
