Abstract
Description
Technical Field
[0001] The present application relates to the technical field of low-voltage power distribution equipment, 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., an isolating switch). The handle is arranged on the outside of the cabinet, the power distribution device is arranged on the inside of the cabinet, and the handle is connected to the power distribution device. With the development of technology, people have higher protection requirements for power distribution cabinets. For example, when foreign objects invade, the protection level of the cabinet of the power distribution cabinet is required to reach IP67. Based on this, since the handle is installed in the power distribution cabinet, the protection level of the handle is required to reach IP67.
[0003] Generally, the protection level of the handle is determined by its airtightness. In order to improve the airtightness of the handle, a seal is usually added to the handle in the prior art. However, after adding the seal, although the seal improves the airtightness of the handle, the seal causes the problem of laborious operation of the handle. Utility Model Content
[0004] In view of this, the embodiments of the present application provide a handle and a power distribution cabinet to solve the problem that the seal in the handle of the prior art easily causes difficulty in operating the handle, thereby facilitating easy operation of the handle.
[0005] In a first aspect, an embodiment of the present application provides a handle. The handle includes a fixing seat, a handle body and a sealing member. The handle body is mounted on the fixing seat along a first direction. The fixing seat includes a first sealing surface. The handle body includes a second sealing surface. The second sealing surface is arranged opposite to the first sealing surface along a second direction, and a first gap is provided between the second sealing surface and the first sealing surface. The second direction has a non-zero angle with the first direction. The sealing member is provided in the first gap and abuts against the first sealing surface and the second sealing surface to seal the fixing seat and the handle body.
[0006] Considering the technical problem that the seal in the existing handle easily causes effort when operating the handle body. The embodiment of the present application sets the first sealing surface of the fixed seat and the second sealing surface of the handle body to be opposite along the second direction, and sets the second direction to have a non-zero angle with the first direction in which the handle body and the fixed seat are installed, so that there is a non-zero angle between the extension direction of the first gap between the first sealing surface and the second sealing surface and the installation direction of the handle body and the fixed seat. In this way, when the seal is filled in the first gap, the handle body and the fixed seat do not need to press the seal to deform, and the seal can seal the fixed seat and the handle body by abutting the first sealing surface and the second sealing surface. Furthermore, when the handle body does not need to press the seal to deform, the friction between the handle body and the seal is small, which can facilitate easy operation of the handle body.
[0007] In a possible design, an annular groove is provided on one side of the fixing seat close to the handle body, and the first sealing surface is configured as the circumferential surface of the annular groove. An annular protrusion is provided on one side of the handle body close to the fixing seat, and the second sealing surface is configured as the side surface of the annular protrusion. Alternatively, an annular protrusion is provided on one side of the fixing seat close to the handle body, and the first sealing surface is configured as the side surface of the annular protrusion. An annular groove is provided on one side of the handle body close to the fixing seat, and the second sealing surface is configured as the circumferential surface of the annular groove.
[0008] According to the above solution, after the handle body and the fixing seat are installed, the annular protrusion will be embedded in the annular groove, and a first gap will exist between the circumference of the annular groove and the side of the annular protrusion. The sealing member can be located in the first gap between the circumference of the annular groove and the side of the annular protrusion, and abut the circumference of the annular groove and the side of the annular protrusion to seal the fixing seat and the handle body.
[0009] In a possible design, the first sealing surface includes a first sub-surface, the second sealing surface includes a first sub-surface, and the sealing component includes a first sub-component. The first sub-component is disposed between the first sub-surface and the first sub-surface, and abuts against the first sub-surface and the first sub-surface.
[0010] Through the above solution, illustratively, after the handle body and the fixing seat are assembled, the first sub-surface and the first sub-surface will form a first gap at a position close to the center of the handle body and the center of the fixing seat. After the first sub-component is located in the first gap, the handle body and the fixing seat will be sealed at a position close to the center of the handle body and the center of the fixing seat.
[0011] In a possible design, the first sealing surface includes a second sub-surface. The second sealing surface includes a second sub-surface. The sealing component includes a second sub-component. The second sub-component is disposed between the second sub-surface and the second sub-surface and abuts against the second sub-surface and the second sub-surface.
[0012] Through the above solution, illustratively, after the handle body and the fixing seat are assembled, the second sub-surface and the second sub-surface will form a first gap at a position close to the edge of the handle body and the edge of the fixing seat. After the second sub-component is located in the first gap, it will seal the handle body and the fixing seat at a position close to the edge of the handle body and the edge of the fixing seat.
[0013] In a possible design, the first sealing surface includes a first sub-surface and a second sub-surface. The second sealing surface includes a first facet and a second facet. The first sub-surface is opposite to the first facet along the second direction, and the second sub-surface is opposite to the second facet along the second direction. The sealing component includes a first sub-component and a second sub-component. The first sub-component is arranged between the first sub-surface and the first facet, and abuts the first sub-surface and the first facet. The second sub-component is arranged between the second sub-surface and the second facet, and abuts the second sub-surface and the second facet.
[0014] Through the above scheme, illustratively, after the handle body and the fixing seat are assembled, the first sub-surface and the first facet will form a first gap at a position close to the center of the handle body and the center of the fixing seat, and the second sub-surface and the second facet will form a first gap at a position close to the edge of the handle body and the edge of the fixing seat. After the first seal is located in the first gap between the first sub-surface and the first facet, and the second seal is located in the first gap between the second sub-surface and the second facet, the first seal and the second seal can seal the handle body and the fixing seat at two positions at the same time to improve the sealing efficiency of the handle body and the fixing seat.
[0015] In a possible design, a second gap is provided between a bottom surface of the annular groove and a top surface of the annular protrusion.
[0016] Through the above solution, the existence of the second gap will prevent the bottom surface of the annular groove from contacting the top surface of the annular protrusion. In the case where the bottom surface of the annular groove does not contact the top surface of the annular protrusion, there will be no force between the bottom surface of the annular groove and the top surface of the annular protrusion. Furthermore, when the operating handle body rotates, there will be no force between the bottom surface of the annular groove and the top surface of the annular protrusion to prevent the handle body from rotating, which can facilitate easy operation of the handle body.
[0017] In some possible designs, the bottom surface of the annular groove abuts against the top surface of the annular protrusion.
[0018] Through the above solution, although there is force between the bottom surface of the annular groove and the top surface of the annular protrusion, the force is much smaller than the sum of the friction force between the fixed seat and the sealing ring and the friction force between the sealing ring and the handle body in the prior art. In this way, compared with the prior art, the handle body of this embodiment can be operated more labor-saving than the handle body of the prior art.
[0019] In a possible design, the handle further includes a connecting member. The connecting member includes a first end and a second end. The first end of the connecting member is connected to the handle body, and a fixing seat is sleeved between the first end and the second end of the connecting member.
[0020] Through the above solution, the connecting piece can be used as an intermediate connecting piece to securely mount the handle body on the fixing seat. Further, when the handle body and the fixing seat are mounted through the connecting piece, the connecting piece can rotate with the handle body, and the handle body and the connecting piece can rotate relative to the fixing seat.
[0021] In a possible design, a first connection hole is provided on a side of the handle body facing the fixing seat. A through hole is provided on a side of the fixing seat close to the handle body. The connecting member includes a connecting screw and a connecting body with a second connection hole, and the connecting body includes a first end and a second end. The first end of the connecting body passes through the through hole and is close to the handle body, the connecting screw passes through the second connection hole and is fixed to the first connection hole, and the fixing seat is sleeved between the first end and the second end of the connecting body.
[0022] Through the above solution, the connecting screw can pass through the second connecting hole of the connecting body and be fixed to the first connecting hole of the handle body, so as to realize the fixing of the connecting piece and the handle body. On the basis that the connecting piece is fixed to the handle body, when the fixing seat is sleeved on the first end and the second end of the connecting body, the connecting body can be used as an intermediate connecting piece to install the handle body on the fixing seat.
[0023] In a possible design, the second end of the connecting body is provided with an abutting protrusion, and the fixing seat is sleeved between the first end of the connecting body and the abutting protrusion. A third gap is provided between the abutting protrusion and the surface where the through hole of the fixing seat is located.
[0024] Through the above solution, during the rotation of the handle body and the connecting body, the fixing seat will always be located between the handle body and the abutting protrusion, and the handle body and the connecting body will not be separated from the fixing seat. Furthermore, the setting of the third gap will eliminate the interaction force between the abutting protrusion and the fixing seat, and thus, when the handle body is rotated, the fixing seat will not have the force to prevent the connecting body from rotating, so that the handle body can be easily operated.
[0025] In a second aspect, an embodiment of the present application further provides a power distribution cabinet. The power distribution cabinet includes a cabinet, a power distribution device, and the handle of the first aspect. The handle is mounted on the outer wall of the cabinet. The power distribution device is disposed inside the cabinet. The handle is connected to the power distribution device.
[0026] On the basis that the handle body in the aforementioned handle can be easily operated, the handle body in the power distribution cabinet of this embodiment can also be easily operated. Furthermore, it can also be easier to operate the handle body to control the opening or closing of the power distribution equipment.

[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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 "top", "bottom", "inside", "outside", "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 a limitation on the present application.
[0044] Furthermore, the expressions indicating directions such as the X direction and the Y direction used to illustrate the operation and construction of the components of the present embodiment are not absolute but relative, and although these indications are appropriate when the components are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.
[0045] 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.
[0046] 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 seat, such as a fixed connection through screws, bolts or other fixing seats; 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.
[0047] In the existing handles used in power distribution cabinets, a sealing ring is usually installed between the handle body and the fixing seat. The sealing ring fills the gap between the handle body and the fixing seat to improve the sealing performance between the handle body and the fixing seat.
[0048] When installing the sealing ring between the handle body and the fixing seat, in the prior art, the handle body, the sealing ring and the fixing seat are arranged along the installation direction of the handle body and the fixing seat (at this time, the direction in which the handle body presses the sealing ring and the direction in which the fixing seat presses the sealing ring are the same as or opposite to the installation direction of the handle body and the fixing seat). In this way, the handle body and the fixing seat are controlled to be infinitely close by other components (for example, a pressure plate), so that the handle body and the fixing seat jointly squeeze the sealing ring, causing the sealing ring to deform to fill the gap between the handle body and the fixing seat.
[0049] However, based on the joint extrusion of the sealing ring by the handle body and the fixing seat, the inventors found that when the fixing seat is fixed and the handle body is operated to rotate to drive other components (for example, a square shaft) to rotate so that other components control the opening or closing of the power distribution equipment (for example, a disconnector) in the distribution cabinet, there is a large friction force between the sealing ring and the handle body. This large friction force will prevent the handle body from rotating, resulting in difficulty in operating the handle body.
[0050] Based on this, an embodiment of the present application provides a handle, by setting the sealing ring against the handle body, and the direction of the sealing ring against the fixed seat to have a non-zero angle with the installation direction of the handle body and the fixed seat, so that the sealing ring can fill the gap between the handle body and the fixed seat without being deformed by the handle body and the fixed seat.
[0051] 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.
[0052] The present application embodiment provides a handle 1. Figures 1 to 3The handle 1 includes a fixing seat 11, a handle body 12 and a sealing member 13. The handle body 12 is mounted on the fixing seat 11 along a first direction X. The fixing seat 11 includes a first sealing surface M1. The handle body 12 includes a second sealing surface M2. The second sealing surface M2 is arranged opposite to the first sealing surface M1 along a second direction Y, and a first gap JX1 is provided between the second sealing surface M2 and the first sealing surface M1. The second direction Y has a non-zero angle with the first direction X. The sealing member 13 is provided in the first gap JX1, and abuts against the first sealing surface M1 and the second sealing surface M2 to seal the fixing seat 11 and the handle body 12.
[0053] In this embodiment, when the second direction Y between the first sealing surface M1 and the second sealing surface M2 has a non-zero angle with the installation direction of the handle body 12 and the fixing seat 11, the extension direction of the first gap JX1 between the first sealing surface M1 and the second sealing surface M2 will have a non-zero angle with the installation direction of the handle body 12 and the fixing seat 11. In this way, when the seal 13 is filled in the first gap JX1, the handle body 12 and the fixing seat 11 do not need to press the seal 13 to deform, and the seal 13 can seal the fixing seat 11 and the handle body 12 by abutting the first sealing surface M1 and the second sealing surface M2. Furthermore, when the handle body 12 does not need to press the seal 13 to deform, the friction between the seal 13 and the handle body 12 is small, which can facilitate easy operation of the handle body 12.
[0054] When the handle body 12 is installed on the fixing seat 11 along the first direction X, specifically, the handle body 12 and the fixing seat 11 can be arranged relative to each other along the first direction X. Then the handle body 12 is controlled to approach the fixing seat 11 along the first direction X. Finally, the handle body 12 is installed on the fixing seat 11. Figure 1 Taking the state shown as an example, the first direction X may be an up-down direction.
[0055] The first sealing surface M1 may be located on a side of the fixing seat 11 close to the handle body 12. Correspondingly, the second sealing surface M2 may be located on a side of the handle body 12 close to the fixing seat 11. Both the first sealing surface M1 and the second sealing surface M2 may be set to be smooth surfaces or rough surfaces, and the embodiment of the present application does not specifically limit this.
[0056] When the first sealing surface M1 and the second sealing surface M2 are opposite to each other along the second direction Y, they can be partially opposite or completely opposite to each other. Exemplarily, when the first sealing surface M1 and the second sealing surface M2 are partially opposite to each other along the second direction Y, the projection of the first sealing surface M1 and the projection of the second sealing surface M2 partially overlap in the second direction Y. Or, for example, when the first sealing surface M1 and the second sealing surface M2 are completely opposite to each other along the second direction Y, the projection of the first sealing surface M1 and the projection of the second sealing surface M2 completely overlap in the second direction Y. Among them, the second direction Y can be Figure 1 The left and right direction may also be other directions between the up and down directions and the left and right directions, and the embodiments of the present application do not make any special limitations on this.
[0057] The second direction Y and the first direction X have a non-zero angle, which means that the angle between the second direction Y and the first direction X is greater than 0° and less than or equal to 90°. For example, the second direction Y and the first direction X may have an angle of 10°, 30°, 60° or 90°.
[0058] The first gap JX1 may be a gap formed between the first sealing surface M1 and the second sealing surface M2 after the handle body 12 and the fixing seat 11 are assembled.
[0059] The seal 13 may be an O-ring. The material of the seal 13 may include nitrile rubber. When the seal 13 is disposed in the first gap JX1, illustratively, before the handle body 12 and the fixing seat 11 are assembled, the seal 13 may be sleeved on the handle body 12 or the fixing seat 11, so that after the handle body 12 and the fixing seat 11 are installed, the seal 13 is located in the first gap JX1.
[0060] In the above embodiment, the shape of the handle body 12 and the shape of the fixing seat 11 can be various. Based on the different shapes of the handle body 12 and the fixing seat 11, the first sealing surface M1 and the second sealing surface M2 are also arranged at different positions. For ease of understanding, the following is a detailed description in conjunction with the accompanying drawings.
[0061] In some embodiments, see Figure 2 The fixing seat 11 has an annular groove AC on one side close to the handle body 12, and the first sealing surface M1 is configured as the circumference of the annular groove AC. The handle body 12 has an annular protrusion TQ on one side close to the fixing seat 11, and the second sealing surface M2 is configured as the side of the annular protrusion TQ.
[0062] In this embodiment, after the handle body 12 is installed on the fixing seat 11, the annular protrusion TQ of the handle body 12 will be embedded in the annular groove AC of the fixing seat 11, and a first gap JX1 will exist between the circumference of the annular groove AC and the side of the annular protrusion TQ. The sealing member 13 can be located in the first gap JX1 between the circumference of the annular groove AC and the side of the annular protrusion TQ, and abut the circumference of the annular groove AC and the side of the annular protrusion TQ to seal the fixing seat 11 and the handle body 12.
[0063] The annular groove AC may be a U-shaped groove or a C-shaped groove, etc. The peripheral surface of the annular groove AC refers to the surface adjacent to the opening. The first sealing surface M1 may be one or both of the two peripheral surfaces of the annular groove AC. The embodiment of the present application does not specifically limit the specific structure of the annular groove AC and the specific position of the first sealing surface M1.
[0064] In addition, the cross section of the annular protrusion TQ may be a trapezoid or an arc, etc. The side surface of the annular protrusion TQ refers to the surface opposite to the circumferential surface of the annular groove AC. The second sealing surface M2 may also be one or both of the two side surfaces of the annular protrusion TQ. The embodiment of the present application does not specifically limit this.
[0065] In other embodiments, please continue to refer to Figure 3 The fixing seat 11 has an annular protrusion TQ on one side close to the handle body 12, and the first sealing surface M1 is configured as the side of the annular protrusion TQ. The handle body 12 has an annular groove AC on one side close to the fixing seat 11, and the second sealing surface M2 is configured as the circumference of the annular groove AC.
[0066] In this embodiment, after the handle body 12 is installed on the fixing seat 11, the annular protrusion TQ of the fixing seat 11 will be embedded in the annular groove AC of the handle body 12, and a first gap JX1 will exist between the circumference of the annular groove AC and the side of the annular protrusion TQ. The sealing member 13 can be located in the first gap JX1 between the circumference of the annular groove AC and the side of the annular protrusion TQ, and abut the circumference of the annular groove AC and the side of the annular protrusion TQ to seal the fixing seat 11 and the handle body 12.
[0067] Among them, the structure and arrangement of the annular groove AC and the annular protrusion TQ may be the same as those of some of the aforementioned embodiments, and will not be repeated here.
[0068] Based on the above structure of the handle body 12 and the fixing seat 11 , there may be various configurations of the first sealing surface M1 and the second sealing surface M2 , as well as the configuration position of the sealing member 13 . For ease of understanding, detailed descriptions are given below with reference to the accompanying drawings.
[0069] In some embodiments, see Figure 4 The first sealing surface M1 includes a first sub-surface M11. The second sealing surface M2 includes a first sub-surface M21. The sealing member 13 includes a first sub-member 131. The first sub-member 131 is disposed between the first sub-surface M11 and the first sub-surface M21, and abuts against the first sub-surface M11 and the first sub-surface M21.
[0070] Wherein, in the case where the fixing seat 11 is provided with an annular groove AC and the handle body 12 is provided with an annular protrusion TQ, the first sub-surface M11 may be a groove surface in the annular groove AC close to the center of the fixing seat 11. Correspondingly, the first facet M21 may be a side surface of the annular protrusion TQ close to the center of the handle body 12. On the contrary, in the case where the fixing seat 11 is provided with an annular protrusion TQ and the handle body 12 is provided with an annular groove AC, the first sub-surface M11 may be a side surface of the annular protrusion TQ close to the center of the fixing seat 11, and correspondingly, the first facet M21 may be a groove surface in the annular protrusion TQ close to the center of the handle body 12.
[0071] In this embodiment, after the handle body 12 and the fixing seat 11 are assembled, the first sub-surface M11 and the first sub-surface M21 form a first gap JX1 at a position close to the center of the handle body 12 and the center of the fixing seat 11. After the first sub-component 131 is located in the first gap JX1, it seals the handle body 12 and the fixing seat 11 at a position close to the center of the handle body 12 and the center of the fixing seat 11.
[0072] In other embodiments, see Figure 5 The first sealing surface M1 includes a second sub-surface M12. The second sealing surface M2 includes a second sub-surface M22. The sealing member 13 includes a second sub-member 132. The second sub-member 132 is disposed between the second sub-surface M12 and the second sub-surface M22, and abuts against the second sub-surface M12 and the second sub-surface M22.
[0073] Wherein, in the case where the fixing seat 11 is provided with an annular groove AC and the handle body 12 is provided with an annular protrusion TQ, the second sub-surface M12 may be a groove surface in the annular groove AC close to the edge of the fixing seat 11. Correspondingly, the second facet M22 may be a side surface of the annular protrusion TQ close to the edge of the handle body 12. On the contrary, in the case where the fixing seat 11 is provided with an annular protrusion TQ and the handle body 12 is provided with an annular groove AC, the second sub-surface M12 may be a side surface of the annular protrusion TQ close to the edge of the fixing seat 11, and correspondingly, the second facet M22 may be a groove surface in the annular protrusion TQ close to the edge of the handle body 12.
[0074] In this embodiment, after the handle body 12 and the fixing seat 11 are assembled, the second sub-surface M12 and the second sub-surface M22 form a first gap JX1 at a position close to the edge of the handle body 12 and the edge of the fixing seat 11. After the second sub-component 132 is located in the first gap JX1, it seals the handle body 12 and the fixing seat 11 at a position close to the edge of the handle body 12 and the edge of the fixing seat 11.
[0075] It should be noted that the second sub-surface M12 in this embodiment may be located between the first sub-surface M11 in the above embodiment and the edge of the fixing seat 11. Also, the second sub-surface M22 in this embodiment may be located between the second sub-surface M22 in the above embodiment and the edge of the handle body 12.
[0076] In some other embodiments, see Figure 6 , the first sealing surface M1 includes a first sub-surface M11 and a second sub-surface M12. The second sealing surface M2 includes a first facet M21 and a second facet M22. The first sub-surface M11 is opposite to the first facet M21 along the second direction Y, and the second sub-surface M12 is opposite to the second facet M22 along the second direction Y. The sealing component 13 includes a first sub-component 131 and a second sub-component 132. The first sub-component 131 is arranged between the first sub-surface M11 and the first facet M21, and abuts against the first sub-surface M11 and the first facet M21. The second sub-component 132 is arranged between the second sub-surface M12 and the second facet M22, and abuts against the second sub-surface M12 and the second facet M22.
[0077] The positions of the first sub-surface M11 and the first facet M21 may refer to some of the aforementioned embodiments. Correspondingly, the positions of the second sub-surface M12 and the second facet M22 may refer to some of the aforementioned other embodiments. No further description is given here.
[0078] In this embodiment, after the handle body 12 and the fixing seat 11 are assembled, the first sub-surface M11 and the first facet M21 will form a first gap JX1 near the center of the handle body 12 and the center of the fixing seat 11, and the second sub-surface M12 and the second facet M22 will form a first gap JX1 near the edge of the handle body 12 and the edge of the fixing seat 11. After the first seal 13 is located in the first gap JX1 between the first sub-surface M11 and the first facet M21, and the second seal 13 is located in the first gap JX1 between the second sub-surface M12 and the second facet M22, the first seal 13 and the second seal 13 can seal the handle body 12 and the fixing seat 11 at two locations at the same time to improve the sealing efficiency of the handle body 12 and the fixing seat 11.
[0079] In addition, after the fixing seat 11, the handle body 12 and the sealing member 13 are assembled, there may be various positional relationships between the bottom surface of the annular groove AC and the top surface of the annular protrusion TQ.
[0080] In some embodiments, see Figures 2 to 6 There is a second gap JX2 between the bottom surface of the annular groove AC and the top surface of the annular protrusion TQ.
[0081] In this embodiment, the existence of the second gap JX2 makes the bottom surface of the annular groove AC not in contact with the top surface of the annular protrusion TQ. In the case where the bottom surface of the annular groove AC does not contact the top surface of the annular protrusion TQ, there will be no force between the bottom surface of the annular groove AC and the top surface of the annular protrusion TQ. Furthermore, when the operating handle body 12 rotates, there will be no force between the bottom surface of the annular groove AC and the top surface of the annular protrusion TQ to prevent the handle body 12 from rotating, which can facilitate easy operation of the handle body 12.
[0082] The bottom surface of the groove refers to the surface opposite to the opening of the groove, and the top surface of the annular protrusion TQ refers to the surface directly opposite to the bottom surface of the groove.
[0083] In addition, the bottom surface of the groove and the top surface of the annular protrusion TQ can be set to be a smooth surface or a rough surface, etc. The embodiment of the present application does not make any special limitation on this.
[0084] In some other embodiments, the bottom surface of the annular groove AC abuts against the top surface of the annular protrusion TQ (not shown in the figures).
[0085] In this embodiment, when the bottom surface of the annular groove AC abuts against the top surface of the annular protrusion TQ, although there is a force between the bottom surface of the annular groove AC and the top surface of the annular protrusion TQ, the force is much smaller than the sum of the friction force of the fixing seat 11 on the sealing ring and the friction force of the sealing ring on the handle body 12 in the prior art. In this way, compared with the prior art, the handle body 12 of this embodiment can be operated more labor-saving than the handle body 12 of the prior art.
[0086] Based on the above statements, after the handle body 12 is installed on the fixing seat 11 , the handle body 12 needs to rotate relative to the fixing seat 11 . Therefore, as the handle body 12 rotates, the handle body 12 may be separated from the fixing seat 11 .
[0087] Based on this, please combine Figure 1 and Figure 7 In the embodiment of the present application, the handle 1 is configured to further include a connecting member 14. The connecting member 14 includes a first end and a second end. The first end of the connecting member 14 is connected to the handle body 12, and the fixing seat 11 is sleeved between the first end and the second end of the connecting member 14.
[0088] In the embodiment of the present application, the first end of the connecting member 14 can be fixedly connected to the handle body 12. The fixing seat 11 can be sleeved between the first end and the second end of the connecting member 14, and the connecting member 14 can rotate relative to the fixing seat 11. In this way, the connecting member 14 can be used as an intermediate connecting member 14 to enable the handle body 12 to be securely mounted on the fixing seat 11.
[0089] Furthermore, when the handle body 12 and the fixing seat 11 are installed through the connecting piece 14 , the connecting piece 14 can rotate along with the handle body 12 , and the handle body 12 and the connecting piece 14 can rotate relative to the fixing seat 11 .
[0090] Among them, see Figure 7 The connecting member 14 can be configured as a substantially cylindrical structure. The portion of the connecting member 14 close to one end surface is the first end of the connecting member 14. The portion of the connecting member 14 close to the other end surface is the second end of the connecting member 14.
[0091] In some embodiments, please continue to combine Figure 1 and Figure 7 , a first connection hole K1 is provided on the side of the handle body 12 facing the fixing seat 11. A through hole K2 is provided on the side of the fixing seat 11 close to the handle body 12. The connecting member 14 includes a connecting screw 142 and a connecting body 141 having a second connection hole K3, and the connecting body 141 includes a first end and a second end. The first end of the connecting body 141 passes through the through hole K2 and is close to the handle body 12, the connecting screw 142 passes through the second connection hole K3 and is fixed to the first connection hole K1, and the fixing seat 11 is sleeved between the first end and the second end of the connecting body 141.
[0092] In this embodiment, when the connecting screw 142 passes through the second connecting hole K3 and is fixed to the first connecting hole K1, the connecting screw 142 can fix the connecting body 141 to the handle body 12, so as to achieve the fixation of the connecting member 14 and the handle body 12. On the basis that the connecting member 14 is fixed to the handle body 12, when the fixing seat 11 is sleeved on the first end and the second end of the connecting body 141, the connecting member 14 can be used as an intermediate connecting member 14 to install the handle body 12 on the fixing seat 11.
[0093] The first connection hole K1 may be a blind hole, specifically a threaded hole or a light hole. The through hole K2 may be a light hole. The second connection hole K3 may be a through hole, specifically a threaded hole or a light hole that is the same as the first connection hole K1.
[0094] The connecting body 141 may be a substantially cylindrical structure. The portion of the connecting body 141 close to one end surface is the first end of the connecting member 14. The portion of the connecting body 141 close to the other end surface is the second end of the connecting member 14.
[0095] Please continue to combine Figure 1 and Figure 7, a boss may be provided at the first end of the connecting body 141 close to the handle body 12. A groove adapted to the boss may be provided at one side of the handle body 12 close to the connecting body 141. When the connecting screw 142 connects the connecting body 141 to the handle body 12, the boss may extend into the groove, and the side wall of the boss may abut against the groove wall of the groove. In this way, when the handle body 12 is operated to rotate, the connecting member 14 can rotate synchronously with the handle body 12.
[0096] In some embodiments, please continue to combine Figure 1 and Figure 7 The second end of the connecting body 141 is provided with a contact convex portion TB, and the fixing seat 11 is sleeved between the first end of the connecting body 141 and the contact convex portion TB. A third gap JX3 is provided between the contact convex portion TB and the surface where the through hole K2 of the fixing seat 11 is located.
[0097] In this embodiment, when the fixing seat 11 is sleeved between the first end of the connecting body 141 and the abutting protrusion TB, the fixing seat 11 will always be located between the handle body 12 and the abutting protrusion TB during the rotation of the handle body 12 and the connecting body 141. In this way, the handle body 12 and the connecting body 141 will not be separated from the fixing seat 11 during the rotation.
[0098] Furthermore, when a third gap JX3 is set between the abutting protrusion TB and the surface where the through hole K2 of the fixing seat 11 is located, the third gap JX3 will eliminate the interaction force between the abutting protrusion TB and the fixing seat 11. Therefore, when the operating handle body 12 is rotated, the fixing seat 11 will not have a force to prevent the connecting body 141 from rotating, so that the handle body 12 can be easily operated.
[0099] The radial dimension of the abutting protrusion TB may be greater than the radial dimension of the through hole K2, so that the abutting protrusion TB can limit the fixing seat 11. The radial direction may be perpendicular to the first direction X mentioned above.
[0100] The embodiment of the present application also provides a power distribution cabinet. The power distribution cabinet includes a cabinet, a power distribution device and the aforementioned handle 1. The handle 1 is installed on the outer wall of the cabinet. The power distribution device is arranged inside the cabinet. The handle 1 is connected to the power distribution device.
[0101] On the basis that the handle body 12 in the aforementioned handle 1 can be easily operated, the handle body 12 in the power distribution cabinet of this embodiment can also be easily operated. Furthermore, it can also be easier to operate the handle body 12 to control the opening or closing of the power distribution equipment.
[0102] The cabinet, the power distribution equipment, the way the handle 1 is installed on the outer wall of the cabinet, the way the power distribution equipment is arranged in the cabinet, and the way the handle 1 is connected to the power distribution equipment can all be prior art.
