However, the existing wooden frame fixing method has obvious limitations. Although the wooden frame can limit the horizontal movement of the surge arrester mounting base to a certain extent, it cannot prevent the surge arrester from rotating relative to the bottom plate of the wooden crate, making the surge arrester prone to tipping over during transportation. Utility Model Content
[0003] In view of this, in order to solve the problem mentioned above that the wooden frame method restricts the rotation of the surge arrester relative to the bottom of the wooden box, making the surge arrester prone to tipping over during transportation, this application provides a packaging device for packaging surge arresters. The device can fix the first connecting seat to the bottom pallet of the packaging device by snap-fit connection, so as to restrict the movement and rotation of the surge arrester by fixing the first connecting seat and prevent the surge arrester from tipping over.
[0004] This application provides a packaging device for packaging a surge arrester. The surge arrester has a first mounting base at its first end and a second mounting base at its second end. The first and second mounting bases are used to be bolted to a grounding line of a power system. The first mounting base has multiple mounting through holes for the bolts to pass through. The packaging device includes a bottom tray, a top tray, and a fixing buckle. When the packaging device is in the packaging state for the surge arrester: the first mounting base is placed on the surface of the bottom tray, the surface of the bottom tray is connected to the fixing buckle, and a portion of the fixing buckle extends into one of the mounting through holes of the first mounting base; the second mounting base at the second end of the surge arrester abuts against the top tray.
[0005] In one possible implementation, the fixing buckle includes a fixing part and a bending part, the surface of the bottom tray is fixedly connected to the fixing part, a first end of the bending part is connected to the fixing part, the bending part extends from the fixing part to the side of the first mounting seat opposite to the bottom tray, and a second end of the bending part extends from the side of the first mounting seat opposite to the bottom tray into the mounting through hole.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0019] In the description of this application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. "First," "second," etc., are only used to distinguish each other, and do not indicate their degree of importance or order, etc. "Parallel," "perpendicular," etc., are not strict mathematical and / or geometric limitations, and also include errors that can be understood by those skilled in the art and are permissible in manufacturing or use.
[0020] As mentioned earlier, during the transportation of surge arresters, the mounting base at the end of the surge arrester is usually placed on the bottom of a wooden crate, and the movement of the mounting base along the bottom of the crate is restricted by a wooden frame installed on the bottom of the crate. However, the existing wooden frame fixing method has obvious limitations. Although the wooden frame can limit the horizontal movement of the surge arrester mounting base to a certain extent, it cannot prevent the surge arrester from rotating relative to the bottom of the crate. This makes the surge arrester prone to tipping over during transportation, which may not only cause damage to the product inside the packaging box, but also pose a safety hazard when the customer opens the box, increasing the risk of personal injury.
[0021] This application provides a packaging device for packaging surge arresters. The surge arrester has a first mounting base at its first end and a second mounting base at its second end. The first and second mounting bases are used for bolt mounting to a grounding line in a power system. The first mounting base has multiple through holes for the bolts to pass through. The packaging device includes a bottom tray, a top tray, and a fixing buckle. When the packaging device is in the packaging state for the surge arrester: the first mounting base is placed on the surface of the bottom tray, and the surface of the bottom tray is connected to the fixing buckle. A portion of the fixing buckle extends into one of the through holes of the first mounting base, so that the bottom tray can be engaged with the first end of the surge arrester via the fixing buckle. The second mounting base at the second end of the surge arrester abuts against the top tray. The fixing buckle can fix a first connecting seat to the bottom tray, thereby restricting the movement and rotation of the surge arrester at its first end by fixing the first connecting seat, preventing the surge arrester from tipping over. Furthermore, a portion of the fixing clip extends into a mounting through hole of the first mounting base. This mounting through hole increases the force point for the fixing clip to secure the first mounting base, strengthening the fixing clip's restriction on the movement and rotation of the surge arrester plate, thus better preventing the surge arrester from tipping over. A second mounting base is provided at the second end of the surge arrester, abutting against the top tray. This second mounting base can impede the movement of the second end of the surge arrester, further preventing the surge arrester from tipping over.
[0022] It should be noted that the accompanying drawings in this application are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this application in any way. They are not necessarily drawn to scale.
[0023] The following is in conjunction with the appendix Figure 1-4 The packaging device 100 for packaging surge arresters 200 provided in the embodiments of this application will be described in detail.
[0024] like Figure 1 and Figure 2As shown, the surge arrester 200 has a first mounting base 210 at its first end and a second mounting base 220 at its second end. The main body 230 of the surge arrester 200 can be installed between the first mounting base 210 and the second mounting base 220. The first mounting base 210 and the second mounting base 220 are used to be installed in the grounding line of the power system by bolts. The first mounting base 210 is provided with a plurality of mounting through holes 211 for bolts to pass through. Only one surge arrester 200 can be installed in the grounding line, or multiple surge arresters 200 can be installed. In the latter case, multiple surge arresters 200 can be connected in series in the grounding line of the power system through the first mounting base 210 and the second mounting base 220. For example, the power system can be a circuit system such as an overhead transmission line for power supply. One of the first mounting base 210 and the second mounting base 220 can be connected to a connection structure connected to the conductor of the overhead transmission line, and the other can be connected to a connection structure connected to ground. Thus, when the voltage of the conductor of the overhead transmission line is too high, a path can be formed between the conductor and the ground through the surge arrester 200 to discharge the conductor. The specific working principle of the surge arrester 200 can be found in related technologies and will not be elaborated here. The power system can also be an electrical device such as a transformer or frequency converter. In this case, one of the first mounting base 210 and the second mounting base 220 can be connected to a connection structure connected to the grounding structure (e.g., the outer body) of the transformer or frequency converter, and the other can be connected to a connection structure connected to ground.
[0025] Optionally, the surge arrester 200 can be a composite-jacketed zinc oxide surge arrester 200, and the first mounting base 210 can include a flange, with a mounting through hole 211 located on the flange, and the central axis of the mounting through hole 211 being perpendicular to the flange surface.
[0026] The packaging device 100 includes a bottom tray 110, a top tray 120, and a fixing buckle 130. When the packaging device 100 is in the packaging state of packaging the surge arrester 200: the first mounting seat 210 is placed on the surface of the bottom tray 110, the surface of the bottom tray 110 is connected to the fixing buckle 130, a part of the fixing buckle 130 extends into a mounting through hole 211 of the first mounting seat 210, so that the bottom tray 110 is engaged with the first end of the surge arrester 200 through the fixing buckle 130; the second mounting seat 220 of the second end of the surge arrester 200 abuts against the top tray 120.
[0027] The packaging device 100 can package multiple surge arresters 200. For each surge arrester 200, the bottom tray 110 of the packaging device 100 secures the first mounting base 210 of the surge arrester 200 with at least two fixing clips 130. Furthermore, the at least two fixing clips 130 used to secure the same first mounting base 210 are evenly distributed around the periphery of the first mounting base 210 to ensure uniform force distribution on all sides of the first mounting base 210. The number of mounting through holes 211 on the first mounting base is greater than or equal to the number of fixing clips 130 used therefor, so that each fixing clip 130 can partially extend into one mounting through hole 211. This allows the first mounting base 210 to be secured at multiple locations around it using at least two fixing clips 130, which helps to evenly distribute the force from the first mounting base 210 to each fixing clip 130, improving the stability of the engagement between the fixing clips 130 and the first mounting base 210.
[0028] In this embodiment, the packaging device 100 includes a bottom tray 110, a top tray 120, and a fixing buckle 130. When the packaging device 100 is in the packaging state for the surge arrester 200: a first mounting seat 210 is placed on the surface of the bottom tray 110, and the surface of the bottom tray 110 is connected to the fixing buckle 130. A portion of the fixing buckle 130 extends into a mounting through hole 211 of the first mounting seat 210, so that the bottom tray 110 can be engaged with the first end of the surge arrester 200 through the fixing buckle 130. A second mounting seat 220 at the second end of the surge arrester 200 abuts against the top tray 120. The first connecting seat can be fixed to the bottom tray 110 by the fixing buckle 130, so as to restrict the movement and rotation of the surge arrester 200 at the first end of the surge arrester 200 by fixing the first connecting seat 210, and prevent the surge arrester 200 from tipping over. Furthermore, a portion of the fixing buckle 130 extends into a mounting through hole 211 of the first mounting base 210. The mounting through hole 211 increases the force point for the fixing buckle 130 to secure the first mounting base 210, strengthening the restriction of the fixing buckle 130 on the movement and rotation of the surge arrester 200 plate, thus better preventing the surge arrester 200 from tipping over. A second mounting base 220 at the second end of the surge arrester 200 abuts against the top tray 120, which can hinder the movement of the second end of the surge arrester 200, thereby further preventing the surge arrester 200 from tipping over.
[0029] like Figure 3As shown, in some optional embodiments, the fixing buckle 130 includes a fixing part 131 and a bending part 132. The surface of the bottom tray 110 is fixedly connected to the fixing part 131. The first end of the bending part 132 is connected to the fixing part 131. The bending part 132 extends from the fixing part 131 to the side of the first mounting base 210 opposite to the bottom tray 110. The second end of the bending part 132 extends from the side of the first mounting base 210 opposite to the bottom tray 110 into the mounting through hole 211.
[0030] The fixing part 131 and the surface of the bottom tray 110 can be detachably connected, thereby facilitating the removal of the fixing buckle 130 and improving the efficiency of the packaging device 100 in packaging the surge arrester 200. For example, as... Figure 3 As shown, a screw hole 1311 can be provided on the fixing part 131, and the fixing part 131 and the base tray 110 are detachably connected by a screw passing through the screw hole 1311. By providing the second end of the bent part 132 located in the mounting through hole 211, the second end of the bent part 132 can prevent the first mounting seat 210 from moving along the base tray 110. Furthermore, by using the portion of the bent part 132 extending from the fixing part 131 to the side of the first mounting seat 210 facing away from the base tray 110, the movement of the first mounting seat 210 in the direction away from the base tray 110 can be restricted, that is, the formation of a gap between the first mounting seat 210 and the base tray 110 can be prevented, thereby preventing the surge arrester 200 from tilting relative to the base tray 110.
[0031] like Figure 4 As shown, the bending portion 132 includes a first sub-segment 1321, a second sub-segment 1322, and a third sub-segment 1323. The fixing portion 131 is connected to the first end of the first sub-segment 1321, meaning the first end of the bending portion 132 is the first end of the first sub-segment 1321. The fixing portion 131 and the first sub-segment 1321 may be at an angle and not parallel. The second end of the first sub-segment 1321 is connected to the first end of the second sub-segment 1322, and the second end of the second sub-segment 1322 is connected to the first end of the third sub-segment 1323. The second end of the third sub-segment 1323 extends into the mounting through hole 211, and the second end of the bending portion 132 is the second end of the third sub-segment 1323. Optionally, the fixing portion 131 may be parallel to the surface of the base tray 110, the first segment 1321 may be perpendicular to the surface of the base tray 110, the third segment 1323 may be parallel to the first segment 1321, and the second segment 1322 may abut against the side of the first mounting base 210 facing away from the base tray 110. An angle may exist between the first segment 1321 and the second segment 1322. In other optional embodiments, the bending portion 132 may also be other suitable structures, such as a C-shaped structure. The embodiments of this application do not limit the specific shape of the bending portion 132.
[0032] In this embodiment, the bent portion 132 is divided into a first sub-segment 1321, a second sub-segment 1322, and a third sub-segment 1323, which can be interconnected to form a stable structure. By connecting the first sub-segment 1321 to the fixing portion 131, the third sub-segment 1323 extending into the mounting through hole 211, and the second sub-segment 1322 abutting against the side of the first mounting base 210 facing away from the bottom tray 110, the fixing buckle 130 can apply force to the first mounting base 210 in different directions and positions, thereby enhancing the stability of the engagement between the fixing buckle 130 and the first mounting base 210. By setting the first segment 1321 to be perpendicular to the surface of the base tray 110, and the third segment 1323 to be parallel to the first segment 1321, it is possible to avoid the first segment 1321 and the second segment 1322 obstructing the entry of the third segment 1323 into the mounting through hole 211 when installing the fixing clip 130. This allows the second end of the third segment 1323 to be easily installed into the mounting through hole 211, which helps to reduce the installation time of the fixing clip 130.
[0033] like Figure 1 and Figure 2 As shown, in some alternative embodiments, the packaging device 100 includes a strapping 140 that wraps around the bottom tray 110 and the top tray 120 at least once.
[0034] By binding with the straps 140, the bottom tray 110 and the top tray 120 can be kept in contact with the first mounting base 210 and the second mounting base 220 of the surge arrester 200, respectively, so that the top tray 120, the bottom tray 110 and the surge arrester 200 are tightly fixed together to form a whole. This can effectively enhance the stability of the entire packaging device 100, increase the difficulty of the surge arrester 200 moving relative to the bottom tray 110 and the top tray 120, and further prevent the surge arrester 200 from tilting.
[0035] like Figure 2 As shown, in some optional embodiments, a limiting groove 121 is provided on the side of the top tray 120 near the second mounting base 220, and at least a portion of the second mounting base 220 is located in the limiting groove 121. The limiting groove 121 may include a groove bottom facing the bottom tray 110 and a sidewall perpendicular to the groove bottom. The second end of the surge arrester 200 can abut against the groove bottom and sidewall of the limiting groove 121 through the second mounting base 220, so as to prevent the second end of the surge arrester 200 from moving through the groove bottom and sidewall of the limiting groove 121. The limiting groove 121 has multiple sidewalls, and there are at least two opposing sidewalls, so that the limiting groove 121 can restrict the movement of the second mounting base 220 in at least two opposing directions.
[0036] In this embodiment, by setting at least a portion of the second mounting base 220 to be located in the limiting groove 121, the second mounting base 220 can be engaged with the limiting groove 121 of the top tray 120. This allows the second mounting base 220 to be translated relative to the top tray 120 via the side wall of the limiting groove 121. This helps to keep the surge arrester 200 stationary relative to the packaging device 100, thereby further reducing the risk of the surge arrester 200 tipping over during transportation and improving the safety of the surge arrester 200 during transportation.
[0037] In some alternative embodiments, the packaging device 100 includes a bottom tray 110, a plurality of top trays 120 and a plurality of sets of straps 140; one set of straps 140 is wrapped around the bottom tray 110 and the top trays 120.
[0038] Setting multiple top trays 120 improves the flexibility of the packaging device 100 in packaging surge arresters 200. For example, when the surge arresters 200 have different lengths, it is difficult to simultaneously ensure that the top tray 120 abuts against the second end of all surge arresters 200 when using a single top tray 120. However, when using multiple top trays 120, each top tray 120 can abut against the second end of surge arresters 200 of different lengths, thus easily and conveniently packaging surge arresters 200 of different lengths simultaneously, expanding the applicability of the packaging device 100. Setting multiple sets of binding straps 140, with one set of binding straps 140 wrapped around the bottom tray 110 and one top tray 120, ensures that the binding of each top tray 120 does not interfere with each other, simplifying the wrapping method of the binding straps 140 and improving the efficiency of wrapping the binding straps 140.
[0039] like Figure 1 As shown, in some optional embodiments, the bottom tray 110 includes four sides perpendicular to the surface on which the first mounting base 210 is placed. Of these four sides, the first side 111 is provided with a first limiting member 112 including multiple limiting holes 113, and the second side opposite to the first side 111 is provided with a second limiting member including multiple limiting holes 113. The side of the top tray 120 opposite to the bottom tray 110 includes multiple support portions 122 extending in a predetermined direction perpendicular to the first side 111 and the second side. Each set of binding straps 140 includes multiple binding straps 140, one of which passes through a limiting hole 113 in the first limiting member 112 and a limiting hole 113 in the second limiting member, and wraps around a support portion 122 of the bottom tray 110 and the top tray 120. The limiting holes 113 of the first limiting member 112 and the second limiting member, through which a strapping strap 140 passes, can be located on a straight line parallel to a predetermined direction. The support portion 122 of the top tray 120 can protrude away from the bottom tray 110 relative to other portions of the top tray 120 on the side opposite to the bottom tray 110.
[0040] For example, such as Figure 1 As shown, each set of cable ties 140 may include two cable ties 140, one of which passes through a limiting hole 113 of the first limiting member 112 and a limiting hole 113 of the second limiting member, and wraps around a support portion 122 of a top tray 120 and a bottom tray 110; the other cable tie 140 passes through another limiting hole 113 of the first limiting member 112 and another limiting hole 113 of the second limiting member, and wraps around another support portion 122 of the top tray 120 and a bottom tray 110.
[0041] In this embodiment, by providing multiple straps 140 in each group of straps 140, each top tray 120 can be secured by multiple straps 140, which improves the stability of the straps 140 securing the top tray 120. The limiting holes 113 of the first and second limiting members prevent the same strap 140 from slipping on opposite sides of the bottom tray 110, ensuring the straps 140 remain in a fixed position. The support portion 122 extending in a predetermined direction provides a clear winding position for the straps 140 to wrap around the top tray 120, facilitating the winding of the straps 140 during installation.
