Description

Connection structure and outdoor cabinet Technical Field

[0001] This application relates to the technical field of outdoor cabinets, specifically to a connection structure and an outdoor cabinet. Background Technology

[0002] Outdoor cabinets typically consist of a cabinet body and a protective cover. The equipment inside the cabinet generates heat during operation. The protective cover, as part of the ventilation system, guides outside air into the cabinet, creating air convection and carrying away the heat generated by the equipment.

[0003] In existing technologies, cabinets and protective covers are typically connected using screws. However, in actual operation, each time the protective cover is maintained, all the screws on the cover need to be removed one by one. Operators need to spend a lot of time and effort to complete the screw removal work, resulting in low maintenance efficiency of the protective cover. Summary of the Invention

[0004] This application provides a connection structure and an outdoor cabinet that can solve the problem of low maintenance efficiency of existing protective covers.

[0005] To achieve the above objectives, firstly, the outdoor cabinet provided in this application includes:

[0006] The cabinet has an opening;

[0007] A protective cover is installed around the opening;

[0008] The hook includes a first plug-in portion and a first connecting portion connected to both ends of the first plug-in portion. The first connecting portion is connected to the cabinet body. The first plug-in portion is far away from the cabinet body relative to the first connecting portion and is spaced apart from the cabinet body. The first plug-in portion, the first connecting portion and the cabinet body together form a first plug hole.

[0009] The connector is located on the protective cover and is connected to the first socket.

[0010] In some embodiments of this application, the cabinet has a length direction;

[0011] The first connector has a first dimension L1 in the length direction and satisfies: L1≥20mm.

[0012] In some embodiments of this application, the cabinet has a height direction that intersects with the length direction, and the cabinet has a top side and a bottom side that are opposite to each other in the height direction;

[0013] The first insertion portion includes a first main body portion and a first extension portion connected together;

[0014] The hook also includes a first transition portion, and the two ends of the first main body portion in the length direction are connected to the first connecting portion through corresponding first transition portions;

[0015] The first extension portion is disposed near the top side relative to the first transition portion, and the first extension portion has a second dimension L2 in the height direction, satisfying that L2≥20mm.

[0016] In some embodiments of this application, the dimension of the first connecting portion in the height direction is greater than the dimension of the first transition portion in the height direction. In the length direction, the first connecting portion and the first transition portion located on the same side of the first extension portion cooperate with the first extension portion to form a first limiting groove.

[0017] In some embodiments of this application, the connector includes a second plug-in portion and a second connecting portion connected to both ends of the second plug-in portion. The second connecting portion is connected to the protective cover. The second plug-in portion is away from the protective cover relative to the second connecting portion and is spaced apart from the protective cover. The second plug-in portion, the second connecting portion and the protective cover enclose a closed second socket. The first extension portion is engaged with the second socket.

[0018] The second insertion part includes a connected second main body part and a second extension part. The connector also includes a second transition part. The two ends of the second main body part in the length direction are connected to the second connection part through corresponding second transition parts. The second extension part is closer to the bottom side relative to the second transition part. The second extension part is engaged with the first insertion hole.

[0019] In some embodiments of this application, the second connecting portion is larger in height direction than the second transition portion in height direction. In length direction, the second connecting portion and the second transition portion located on the same side of the second extension portion cooperate with the second extension portion to form a second limiting groove; wherein, the first transition portion is connected to the second limiting groove.

[0020] In some embodiments of this application, the cabinet has a width direction, and the width direction, height direction, and length direction intersect each other;

[0021] The second socket has a third dimension L3 in the width direction;

[0022] The first extension has a fourth dimension L4 in the width direction and satisfies: L4 = (0.5 ~ 1) × L3.

[0023] In some embodiments of this application, the first extension portion gradually increases in size in the length direction from the top side to the bottom side.

[0024] In some embodiments of this application, the protective cover includes a cover body and a fixed flange. The cover body covers the outer periphery of the opening. The cover body has an inlet and an outlet that communicate with the internal space of the cover body. The inlet communicates with the opening through the outlet.

[0025] The fixed flange is located inside the cover and near the outlet; the connector is connected to the fixed flange.

[0026] When the hook and connector are connected, both the hook and connector are housed inside the cover.

[0027] In some embodiments of this application, the protective shield further includes:

[0028] Install the flange, connect it to the cover, and set it near the outlet. The flange should be bent inwards towards the cover.

[0029] The outdoor cabinet also includes fasteners, which connect and install the flanges and the cabinet body.

[0030] Secondly, this application also provides a connection structure for connecting a cabinet and a protective cover. The connection structure includes a hook and a connector that cooperate to connect. The hook is disposed on the cabinet and the connector is disposed on the protective cover.

[0031] The hook includes a first plug-in portion and a first connecting portion connected to both ends of the first plug-in portion. The two first connecting portions are connected to the cabinet body. The first plug-in portion is far away from the cabinet body relative to the first connecting portion and is spaced apart from the cabinet body.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0051] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components.

[0052] This application provides a connection structure and an outdoor cabinet, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0053] Outdoor cabinets typically consist of a cabinet body and a protective cover. The external cabinet body usually also has a protective cover, such as an air intake cover, a rain cover, or an electrical component connection cover, which is used to ventilate and dissipate heat inside the cabinet, or to protect the components from dust, water, and sand. The equipment inside the cabinet generates heat during operation. When the protective cover is an air intake cover, it is part of the ventilation system and can guide outside air into the interior of the cabinet to form air convection and carry away the heat generated by the equipment.

[0054] The cabinet serves as the main frame of the outdoor cabinet, providing an enclosed space for the internal equipment and effectively preventing damage from external physical factors. For example, outdoors, the equipment may be subject to collisions from people, touch from animals, or impacts from falling objects. The sturdy outer shell of the cabinet can withstand these unexpected situations and protect the internal equipment from damage.

[0055] Many devices inside outdoor cabinets generate heat during operation. If this heat cannot be dissipated effectively and promptly, it can lead to overheating, affecting the device's performance and lifespan. Protective covers, as an important component of the ventilation system, guide outside air into the cabinet, creating air convection and carrying away the heat generated by the equipment, thus ensuring that the equipment operates within a suitable temperature range. For example, in some outdoor cabinets for communication base stations, protective covers, in conjunction with cooling fans and other equipment, provide excellent heat dissipation for high-power communication equipment.

[0056] Protective covers are typically designed with dust prevention in mind. By cleverly incorporating filters and dust-proof cotton, they effectively block dust and some rainwater from entering while allowing air to pass through. The dust-proof cotton inside the cover needs to be replaced regularly to ensure the equipment's normal operation and stable performance. However, in existing technologies, the cabinet and protective cover are usually connected by screws. Therefore, in actual operation, each time the protective cover is maintained, all the screws on the cover must be removed one by one. This requires operators to spend a significant amount of time and effort to complete the screw removal work, resulting in low maintenance efficiency for the protective cover.

[0057] Therefore, this application provides an outdoor cabinet, which includes a cabinet body, a protective cover, hooks, and connectors. The cabinet body has an opening, and the protective cover covers the outer periphery of the opening. The hook includes a first insertion portion and a first connecting portion connected to both ends of the first insertion portion. The first connecting portion is connected to the cabinet body, and the first insertion portion is located away from the cabinet body relative to the first connecting portion and is spaced apart from the cabinet body. The first insertion portion, the first connecting portion, and the cabinet body together form a first insertion hole. The connector is disposed on the protective cover and is connected to the first insertion hole.

[0058] In this embodiment, the connector and the first socket are connected by a plug-in joint. Therefore, maintenance of the protective cover does not require complex disassembly tools or excessive disassembly steps; simply pulling the connector out of the first socket is sufficient. This significantly saves time and costs during maintenance, improving the efficiency of protective cover maintenance and enabling maintenance personnel to complete tasks in a shorter time.

[0059] The outdoor cabinet provided in the embodiments of this application will be described in more detail below with reference to the accompanying drawings.

[0060] Referring to Figures 1 to 4, assume that cabinet 10 has three intersecting directions: height Z, length X, and width Y. The height Z, length X, and width Y are all perpendicular to each other, and the angle between the approximately perpendicular directions can be between 85° and 95°.

[0061] The outdoor cabinet provided in this embodiment includes a cabinet body 10, a protective cover 20, hooks 1, and connectors 2. The cabinet body 10 has an opening 103, and the protective cover 20 covers the outer periphery of the opening 103. The hooks 1 are disposed on the cabinet body 10, and the connectors 2 are disposed on the protective cover 20. The hooks 1 and connectors 2 are connected to achieve a fixed connection between the cabinet body 10 and the protective cover 20.

[0062] The cabinet 10 provides a stable mounting frame for the internal equipment, isolating the internal electrical, communication, or other functional equipment from the external environment and preventing dust accumulation from affecting heat dissipation and normal operation. At the same time, the cabinet 10 facilitates the installation of the entire outdoor cabinet in a suitable location, such as by fixing it to the ground with anchor bolts, ensuring that the equipment will not loosen due to shaking or vibration in outdoor environments.

[0063] Referring to Figures 1 and 2, the cabinet 10 has an opening 103, and a protective cover 20 is provided around the outer periphery of the opening 103. In one embodiment of this application, the opening 103 can serve as a ventilation opening, allowing outside air to enter the cabinet 10 and carry away the heat generated by the equipment, thereby ensuring that the equipment operates within a suitable temperature range. Alternatively, the opening 103 provides a channel for external cables (such as power cables, signal cables, etc.) to enter and exit the cabinet 10, facilitating cable laying and connection. In other words, the protective cover 20 can be a protective cover 20, a rain cover, an electrical connection protective cover 20, etc., used for ventilation and heat dissipation inside the cabinet 10, or for dustproof, waterproof, and sandproof protection of the components.

[0064] As shown in Figures 2 and 5, the hook 1 includes a first insertion part 11 and a first connecting part 12 connected to both ends of the first insertion part 11. The first connecting part 12 is connected to the cabinet body 10. The first insertion part 11 is located away from the cabinet body 10 relative to the first connecting part 12 and is spaced apart from the cabinet body 10. The first insertion part 11, the first connecting part 12, and the cabinet body 10 together form a closed first insertion hole 13. The connector 2 is connected to the first insertion hole 13. In other words, the gap between the first insertion part 11 and the cabinet body 10 is used to form the first insertion hole 13. The first insertion part 11 is connected to the first connecting part 12 at one end in the length direction X, and the other end is also connected to the first connecting part 12. Both first connecting parts 12 are connected to the cabinet body 10, thereby sealing off the two ends of the gap in the length direction X to form a closed first insertion hole 13. In other words, after the connector 2 is connected to the first socket 13, the connector 2 cannot be dislodged from the first socket 13 in the horizontal direction (length direction X and width direction Y), thus keeping the connector 2 within the first socket 13 at its upper limit in the horizontal direction.

[0065] Optionally, the connector 2 has a metal sheet structure with a certain extension length and width. One end of the connector 2 is connected to the protective cover 20, and the other end of the connector 2 is separated from the protective cover 20 and mates with the first socket 13.

[0066] In this way, since the connector 2 and the first socket 13 are connected by a plug-in joint, maintenance of the protective cover 20 does not require complicated disassembly tools or excessive disassembly steps. Simply pull the connector 2 out of the first socket 13. This greatly saves time and costs during maintenance, improves the maintenance efficiency of the protective cover 20, and allows maintenance personnel to complete maintenance tasks in a shorter time.

[0067] More specifically, the first plug-in portion 11 is connected to the first connecting portion 12 on both sides of the length direction X. The first plug-in portion 11 is fixedly connected to the cabinet 10 through the first connecting portion 12. The first socket 13 is a closed structure formed by the first plug-in portion 11, the first connecting portion 12 located at both ends of the first plug-in portion 11, and the cabinet 10. When the connector 2 is inserted into the first socket 13, the first socket 13 can provide a relatively stable connection to the connector 2 and can simultaneously limit the displacement of the connector 2 in the horizontal direction (e.g., the length direction X and the width direction Y). This can effectively prevent the protective cover 20 from detaching from the cabinet 10 under the action of external forces such as vibration and wind in the outdoor environment, thereby improving the reliability of the connection between the cabinet 10 and the protective cover 20. For example, during the specific installation process, after aligning the connector 2 on the protective cover 20 with the first insertion hole 13 of the cabinet 10, the protective cover 20 is pressed down steadily along the direction of gravity (height direction Z) until the connector 2 and the hook 1 are in place, thus achieving a fixed connection between the cabinet 10 and the protective cover 20.

[0068] During installation, the first socket 13 provides precise positioning guidance for the connector 2, allowing it to be easily and accurately inserted along the extension direction of the first socket 13, ensuring the relative positional accuracy between the cabinet 10 and the protective cover 20. When disassembly is required, such as for maintenance of the internal equipment of the cabinet 10 or replacement of the protective cover 20, the connector 2 can be easily pulled out of the first socket 13, allowing for easy separation of the cabinet 10 and the protective cover 20.

[0069] As shown in Figure 6, in another embodiment of this application, the first insertion portion 11 has a first dimension L1 in the length direction X, satisfying: L1 ≥ 20 mm. When the first dimension L1 is greater than or equal to 20 mm, it can ensure that the first insertion portion 11 and the connector 2 have a relatively large contact area in the length direction X. A larger contact area means that the two can transmit greater force when connected, making the connection between the hook 1 and the connector 2 more stable. At the same time, the magnitude of the frictional force is proportional to the contact area, so a larger frictional force can effectively resist the vibration between the cabinet 10 and the protective cover 20 (such as vibration caused by wind, vibration during equipment transportation, etc.), preventing the connector 2 from falling off from the first extension portion 112.

[0070] In another embodiment of this application, referring to Figures 1 and 6, the cabinet 10 has a top side 101 and a bottom side 102 disposed opposite each other in the height direction Z. The first insertion part 11 includes a first main body part 111 and a first extension part 112 connected along the height direction Z. The hook 1 also includes a first transition part 14. The two ends of the first main body part 111 in the length direction X are connected to the first connecting part 12 through the corresponding first transition part 14. The first extension part 112 is closer to the top side 101 relative to the first transition part 14. The first extension part 112 has a second dimension L2 in the height direction Z, and satisfies that L2 ≥ 20 mm.

[0071] In other words, the height of the first insertion portion 11 in the height direction Z is greater than the height of the first transition portion 14 in the height direction Z. The first insertion portion 11 is divided into a first main body portion 111 and a first extension portion 112 in the height direction Z. The first main body portion 111 is connected to the first connecting portion 12 through the first transition portion 14. The first extension portion 112 is the portion of the first insertion portion 11 that protrudes from or extends beyond the first transition portion 14 in the height direction Z. In some embodiments, the first extension portion 112 has a second dimension L2 in the height direction Z, satisfying that L2 ≥ 20 mm. This achieves the same technical effect as the first dimension L1 of the first insertion portion 11 in the length direction X being greater than or equal to 20 mm in the above technical solution, and will not be elaborated further here.

[0072] It should be noted that the first insertion part 11 has a first dimension L1 in the length direction X, and the hook 1 is installed on the cabinet 10. The first dimension L1 of the first insertion part 11 is smaller than the dimension of the cabinet 10 in the length direction X. For example, when the dimension of the cabinet 10 in the length direction X is 600mm, the first dimension L1 of the first insertion part 11 can be greater than or equal to 20mm and less than or equal to 60mm. For example, when the dimension of the cabinet 10 in the length direction X is 1200mm, the first dimension L1 of the first insertion part 11 can be greater than or equal to 20mm and less than or equal to 120mm. Alternatively, the first dimension L1 of the first insertion part 11 can be greater than or equal to 20mm and less than or equal to 60mm. Compared with embodiments where the first dimension L1 of the first insertion part 11 is between 60mm and 120mm, in this embodiment, a larger number of hooks 1 can be arranged according to the actual situation, and a correspondingly larger number of connectors 2 can be arranged.

[0073] In another embodiment of this application, referring to Figures 2, 5, and 6, the dimension of the first connecting portion 12 in the height direction Z is larger than that of the first transition portion 14 in the height direction Z. In the length direction X, the first connecting portion 12 and the first transition portion 14, located on the same side of the first extension portion 112, cooperate with the first extension portion 112 to form a first limiting groove 15. The first limiting groove 15 can restrict the installation position of the connector 2 in the height direction Z. Specifically, when the protective cover 20 is connected to the cabinet 10, the connector 2 is gradually inserted into the first socket 13 from the top. When the connector 2 abuts against the bottom of the first limiting groove 15 (i.e., the top wall of the first transition portion 14), the connector 2 cannot continue to move downwards, ensuring that the connector 2 can only be installed at a predetermined height position. In other words, when the connector 2 can no longer move downwards under the action of external force, it proves that the connector 2 is installed in place and its size inserted into the first socket 13 is relatively large, rather than just a small part. This can avoid, to a certain extent, problems such as the connector 2 being inserted into the first socket 13 relatively shallowly due to the deviation in installation height, which would lead to loose connection and unstable structure.

[0074] Referring to Figures 2, 4, and 5, in another embodiment of this application, the connector 2 is connected to the protective cover 20 and forms a second insertion hole 21. Specifically, the connector 2 includes a second insertion portion 22 and a second connecting portion 23 connected to both ends of the second insertion portion 22. The second connecting portion 23 is connected to the protective cover 20. The second insertion portion 22 is located away from the protective cover 20 relative to the second connecting portion 23 and is spaced apart from the protective cover 20. The second insertion portion 22, the second connecting portion 23, and the protective cover 20 form a closed second insertion hole 21. The first extension portion 112 of the hook 1 is engaged and connected to the second insertion hole 21.

[0075] The second plug-in portion 22 includes a connected second main body portion 221 and a second extension portion 222. The connector 2 also includes a second transition portion 24. The two ends of the second main body portion 221 in the length direction X are connected to the second connecting portion 23 through the corresponding second transition portion 24. The second extension portion 222 is closer to the bottom side 102 relative to the second transition portion 24. The second extension portion 222 is engaged and connected with the first plug hole 13.

[0076] With the above design, the hook 1 is connected to the second socket 21 (formed by the second main body 221, the second transition part 24, and the second connecting part 23) through the first extension part 112, and the connector 2 is connected to the first socket 13 (formed by the first main body 111, the first transition part 14, and the first connecting part 12) through the second extension part 222. This achieves a dual connection structure between the cabinet 10 and the protective cover 20. This dual connection structure provides a more stable fixing effect, thus more securely fixing the protective cover 20 to the cabinet 10. Compared to connection methods that only connect the first extension part 112 of the hook 1 to the second socket 21, or only connect the second extension part 222 to the first socket 13, the above arrangement can better resist the influence of external forces, such as wind, vibration, or human impact that may be encountered outdoors, thereby ensuring the reliability of the connection between the protective cover 20 and the cabinet 10.

[0077] In other words, hook 1 is connected to the second socket 21 via the first extension 112, and connector 2 is connected to the first socket 13 via the second extension 222. This interlocking design increases the contact area (i.e., the sum of the contact areas of the first insertion part 11 and the second socket 21 and the second insertion part 22 and the first socket 13) without increasing the size of the connection structure, thus making the connection between hook 1 and connector 2 tighter. Compared to traditional snap-fit ​​connections (such as point-to-point snap-fit ​​or point-to-line snap-fit), the above-mentioned connector 2 and hook 1 utilize surface-to-surface contact to increase the contact area, making the connection between them tighter. Especially during the transportation of outdoor cabinets, the protective cover experiences significant vibration; the surface-to-surface contact connection method provides a stable connection and prevents connection failure.

[0078] When installing the connector 2 onto the hook 1, the installer can easily align and insert the connector 2 into the first socket 13 of the hook 1 based on the relative position of the second extension 222 and the first socket 13, making the installation process more convenient and efficient. Simultaneously, under the gravity of the protective cover 20, the connector 2 tends to move downwards, further causing the second extension 222 to embed deeper into the first socket 13. This gravity achieves a self-locking function, making the connection between the connector 2 and the first socket 13 more secure.

[0079] For example, the dimension of the second connecting portion 23 in the height direction Z is larger than the dimension of the second transition portion 24 in the height direction Z. In the length direction X, the second connecting portion 23 and the second transition portion 24, located on the same side of the second extension portion 222, cooperate with the second extension portion 222 to form a second limiting groove 25. That is, both the second extension portion 222 and the second connecting portion 23 protrude from the bottom of the second limiting groove 25 in the height direction Z and extend towards the bottom side 102 of the cabinet 10. The second limiting groove 25 is used to connect with the first transition portion 14, that is, the first transition portion 14 is embedded in the second limiting groove 25 so that the hook 1 and the connector 2 interlock, further enhancing the stability of the connection between the connector 2 and the first transition portion 14.

[0080] Specifically, in the length direction X, the first limiting groove 15 is partially formed by the first extension portion 112 and the first connecting portion 12 protruding from the first transition portion 14 on both sides, so that the second transition portion 24 of the connector 2 is embedded in the first limiting groove 15, which can effectively limit the lateral displacement of the connector 2 in the length direction X. For example, when the cabinet 10 and the protective cover 20 are subjected to external forces (such as wind, vibration, etc.), the first limiting groove 15 can prevent the connector 2 from shifting in the length direction X, thereby ensuring the stability of the connection between the hook 1 and the connector 2 and enhancing the anti-interference ability of the entire outdoor cabinet.

[0081] In another embodiment of this application, referring to Figures 7 and 8, the second socket 21 has a third dimension L3 in the width direction Y. The first extension portion 112 is connected to the second socket 21 and has a fourth dimension L4 in the width direction Y, satisfying: L4 = (0.5~1) × L3. Specifically, the third dimension L3 of the second socket 21 is the distance between the mounting surface of the protective cover 20 and the inner wall surface of the second socket 21 facing the mounting surface, and the fourth dimension L4 of the first extension portion 112 can be understood as the thickness of the first extension portion 112 in the width direction Y. When L4 = (0.5~1) × L3, the first extension portion 112 and the second socket 21 can form a moderately tight fit in the width direction Y. This fit is neither too loose, resulting in an unstable connection, nor too tight, making installation difficult. At the same time, this ratio range provides a certain margin and tolerance for the installation process. Even if there are certain dimensional deviations during manufacturing and installation, a relatively successful installation can still be achieved. For example, if the third dimension L3 of the second socket 21 is slightly larger or smaller due to manufacturing tolerance, as long as the fourth dimension L4 of the first extension portion 112 is within this ratio range, it can still be guaranteed that the two can fit together normally, which reduces the precision requirements for manufacturing and installation, and improves the feasibility of production and the yield rate of products.

[0082] When the fourth dimension L4 approaches the third dimension L3 as closely as possible, the vibration during transportation is minimized, resulting in a more stable structure. For example, the fourth dimension L4 can satisfy any of the following proportional relationships: L4 = 0.5 × L3, L4 = 0.52 × L3, L4 = 0.55 × L3, L4 = 0.58 × L3, L4 = 0.60 × L3, L4 = 0.62 × L3, L4 = 0.65 × L3, L4 = 0.68 × L3, L4 = 0.70 × L3, L4 = 0.71 × L3, L4 = 0.72 × L3 , L4=0.75×L3, L4=0.78×L3, L4=0.80×L3, L4=0.82×L3, L4=0.83×L3, L4=0.85×L3, L4=0 .88×L3, L4=0.90×L3, L4=0.93×L3, L4=0.94×L3, L4=0.95×L3, L4=0.98×L3 or L4=1.0×L3.

[0083] Alternatively, it can be understood that the first socket 13 has a fifth dimension L5 in the width direction Y. The second extension 222 is connected to the second socket 21 and has a sixth dimension L6 in the width direction Y, satisfying: L6 = (0.5~1) × L5. Here, the fifth dimension L5 of the first socket 13 is the distance in the width direction Y between the outer wall of the cabinet 10 and the inner wall of the first socket 13 facing that outer wall, which can also be understood as the distance between the first main body 111 and the cabinet 10 in the width direction Y. The sixth dimension L6 of the second extension 222 can be understood as the thickness of the second extension 222 in the width direction Y.

[0084] When the sixth dimension L6 approaches the fifth dimension L5 as closely as possible, the vibration during transportation is minimized, resulting in a more stable structure. For example, the sixth dimension L6 can satisfy any of the following proportional relationships: L6 = 0.5 × L5, L6 = 0.52 × L5, L6 = 0.55 × L5, L6 = 0.58 × L5, L6 = 0.60 × L5, L6 = 0.62 × L5, L6 = 0.65 × L5, L6 = 0.68 × L5, L6 = 0.70 × L5, L6 = 0.71 × L5, L6 = 0.72 × L5 , L6=0.75×L5, L6=0.78×L5, L6=0.80×L5, L6=0.82×L5, L6=0.83×L5, L6=0.85×L5, L6=0 .88×L5, L6=0.90×L5, L6=0.93×L5, L6=0.94×L5, L6=0.95×L5, L6=0.98×L5 or L6=1.0×L5.

[0085] In some embodiments of this application, the connector 2 has the same structure as the hook 1. Specifically, the second insertion portion 22 has a length dimension X greater than or equal to 20 mm, and the second extension portion 222 has a height dimension Z greater than or equal to 20 mm. This ensures that the second extension portion 222 has a relatively large contact area with the first insertion hole 13, making the connection between the hook 1 and the connector 2 more stable and preventing the second extension portion 222 from falling out of the first insertion hole 13. Since the connector 2 and the hook 1 have the same structure, they can be manufactured using the same molds, tools, and production processes, greatly simplifying the production process and reducing production complexity. For example, during injection molding or machining, it is not necessary to design and manufacture different molds for two different hook structures 1, reducing mold development costs and production preparation time.

[0086] Referring to Figure 6, from the top side 101 to the bottom side 102, the first extension portion 112 gradually increases in size along the length direction X. Thus, when the connector 2 is initially inserted, the smaller starting end of the first extension portion 112 can more easily enter the second socket 21. Then, as the insertion depth increases, the gradually increasing size of the first extension portion 112 creates a self-locking or clamping effect, making it more difficult for the connector 2 to be pulled out of the first extension portion 112. Furthermore, as the size of the first extension portion 112 gradually increases along the length direction X, the fit with the second socket 21 becomes tighter, increasing the stability of the outdoor cabinet.

[0087] It should be noted that, for the embodiment in which "the size of the first extension portion 112 gradually increases in the length direction X from the top side 101 to the bottom side 102", the maximum size of the first extension portion 112 in the length direction X is equal to the first size L1 of the first main body portion 111 in the length direction X, and the first size L1 of the first main body portion 111 in the length direction X needs to be greater than or equal to 20mm.

[0088] For example, the first insertion part 11, the first connecting part 12, and the first transition part 14 are an integral structure, so that the hook 1 forms a complete and continuous component. Compared with a structure assembled from multiple independent parts, the integral structure has better resistance to deformation. Furthermore, it does not require the separate manufacturing of multiple parts and then assembly; for example, it can be directly manufactured using processes such as casting, forging, or one-piece injection molding.

[0089] The two first connecting parts 12 are flat and can fit completely against the outer wall of the cabinet 10, and are welded to the outer wall of the cabinet 10. The weld between the first connecting parts 12 and the cabinet 10 forms a continuous metal joint surface, which makes the connection between the two very strong. Unlike bolted connections or other detachable connections, this connection will not loosen over time, ensuring that the connection between the first connecting parts 12 and the cabinet 10 will not easily loosen or break, thus providing strong support for the entire outdoor cabinet.

[0090] Please refer to Figures 4 and 8. The connector 2 has a second extension 222 on the side near the bottom side 102. The second extension 222 extends toward the bottom side 102 and is connected to the first insertion hole 13, so that the connection between the connector 2 and the hook 1 is tighter in the vertical direction.

[0091] As shown in Figure 9, the protective cover 20 includes a cover body 201 and a fixed flange 202. The cover body 201 covers the outer periphery of the opening 103. The cover body 201 has an inlet 2011 and an outlet 2012 communicating with the internal space of the cover body 201. The inlet 2011 communicates with the opening 103 through the outlet 2012. The fixed flange 202 is disposed inside the cover body 201 and is located near the outlet 2012. The connector 2 is connected to the fixed flange 202. When the hook 1 and the connector 2 are connected, both the hook 1 and the connector 2 are housed inside the cover body 201. That is, when the hook 1 and the connector 2 are connected, both the hook 1 and the connector 2 are hidden inside the cover body 201. By adopting the above method, external space is effectively saved in the overall layout of the cabinet 10 and the protective cover 20. Since both the hook 1 and the connector 2 are housed inside the cover body 201, they can be protected from the direct influence of external environmental factors. Outdoor environments present hazards such as dust, moisture, ultraviolet radiation, and potential mechanical impacts. Concealing both hook 1 and connector 2 within the enclosure 201 prevents wear and corrosion, avoids moisture intrusion causing rust, and thus extends their lifespan. Furthermore, the hook 1 and connector 2 are not visible from the outside of the outdoor cabinet, resulting in a cleaner and more aesthetically pleasing appearance that meets modern demands for equipment design, thereby enhancing the product's market competitiveness.

[0092] Referring to Figures 9-11, the protective cover 20 also includes a mounting flange 203. The mounting flange 203 is connected to the cover body 201 and positioned near the outlet 2012. The mounting flange 203 is bent inwards towards the cover body 201. The outdoor cabinet also includes a fastener 30, which connects the mounting flange 203 and the cabinet body 10. Through this configuration, on the one hand, the fastener 30 provides additional fixing force, further enhancing the reliability of the connection between the cover body 201 and the cabinet body 10, preventing the protective cover 20 from loosening or falling off when subjected to significant external impact, thereby further ensuring the stability of the entire outdoor cabinet structure. On the other hand, the fastener 30 is located inside the protective cover 20 and is not exposed to the outside, effectively preventing corrosion and damage from external environmental factors. In the outdoor environment, dust, moisture, ultraviolet rays, etc., can all adversely affect the fastener 30, causing rust, corrosion, aging, etc. Concealing it inside the cover 201 reduces the chances of these factors coming into contact, improves the durability of the fastener 30, and thus ensures the long-term reliability of the connection.

[0093] For example, the mounting flange 203 has a connection hole 2031. The cabinet 10 has a mounting hole corresponding to the connection hole 2031, and the fastener 30 passes through the connection hole 2031 and the mounting hole.

[0094] The inlet 2011 is located at one end of the protective cover 20 near the bottom side 102 of the cabinet 10, and the connection hole 2031 is located near the bottom side 102 of the protective cover 20. For installers, the fastener 30 can be installed through the inlet 2011, which makes it easier to access and operate without disassembling too many other parts or using special tools to reach these parts, thus facilitating the installation of the fastener 30.

[0095] It should be noted that, as shown in Figure 9, when the protective cover 20 includes both a fixed flange 202 and a mounting flange 203, the fixed flange 202 is located on the top side 101 of the protective cover 20. There are two mounting flanges 203, respectively located on opposite sides of the protective cover 20 along its length direction X. When the hook 1 and the connector 2 are assembled and connected, the end face of the protective cover 20 and the outer wall of the cabinet 10 are tightly fitted together.

[0096] In another embodiment of this application, referring to Figures 1-5, this application also provides a connection structure for connecting a cabinet 10 and a protective cover 20. The connection structure includes a hook 1 and a connector 2 that are engaged in a connection. The hook 1 is disposed on the cabinet 10, and the connector 2 is disposed on the protective cover 20. The hook 1 includes a first insertion portion 11 and a first connecting portion 12 connected to both ends of the first insertion portion 11. The two first connecting portions 12 are connected to the cabinet 10. The first insertion portion 11 is located away from the cabinet 10 relative to the first connecting portions 12 and is spaced apart from the cabinet 10. The first insertion portion 11, the two first connecting portions 12, and the cabinet 10 enclose a closed first insertion hole 13. The connector 2 is engaged in a connection with the first insertion hole 13.

[0097] In this way, since the connector 2 and the first socket 13 are connected by a plug-in joint, maintenance of the protective cover 20 does not require complicated disassembly tools or excessive disassembly steps. Simply pull the connector 2 out of the first socket 13. This greatly saves time and costs during maintenance, improves the maintenance efficiency of the protective cover 20, and allows maintenance personnel to complete maintenance tasks in a shorter time.

[0098] The hook 1 in the connection structure has the same technical features as the hook 1 described in any of the above technical solutions, and the connector 2 in the connection structure has the same technical features as the connector 2 described in any of the above technical solutions. Therefore, the two can solve the same technical problem and achieve the same technical effect, which will not be repeated here.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of protection of the claims.
