Description

Technical Field

[0001] This utility model relates to the field of outgoing line cabinets, and in particular to an outgoing line cabinet door limiting structure. Background Technology

[0002] Currently, the outgoing line cabinet is a current collector that receives signals from the output end of the main cable and branches them to downstream electrical equipment. As an important piece of equipment in the power system, the outgoing line cabinet has the characteristics of compact structure, convenient maintenance and high reliability, and is widely used in industrial power distribution systems, municipal engineering, solar photovoltaic power generation systems and other fields.

[0003] Related technology can be found in Chinese patent application CN117335288A, which discloses a cable outlet cabinet that facilitates adjustment of internal space size. The cabinet includes a cabinet body and a cabinet door. The cabinet body is equipped with a mounting rod and a height adjustment component. The height adjustment component includes two sets of height adjustment columns, a mounting plate slidably disposed between the two sets of height adjustment columns, and a fixing component for fixing the position of the mounting plate. One set of height adjustment columns is L-shaped. The shorter side of the height adjustment column is called the first mounting part, and the other side is called the adjustment part. The adjustment part has a through groove. Both ends of the mounting plate are bent towards the length direction of the height adjustment column. The bent parts at both ends of the mounting plate are called the second mounting parts. The part between the two second mounting parts at both ends of the mounting plate is called the fixing part. The fixing part has several mounting holes. The fixing component passes through the groove and the threaded holes to fix the position of the mounting plate. The fixing component is threadedly connected to the second mounting part of the mounting plate.

[0004] Regarding the aforementioned technologies, cabinet doors typically contain multiple components. Since there is no limiting device, excessive force when opening the cabinet door can cause an excessively large opening angle, impacting the cabinet body and potentially breaking the connection line between the cabinet door and the interior, thus damaging the equipment. This results in low stability when opening and closing the cabinet door. Utility Model Content

[0005] To improve the stability of the opening and closing of the outgoing line cabinet door, this application provides an outgoing line cabinet door limiting structure.

[0006] This application provides a cabinet door limiting structure for outgoing line cabinets, which adopts the following technical solution:

[0007] A cabinet door limiting structure for a cable outlet includes a cabinet door and a cabinet body. The cabinet door is rotatably connected to one side of the cabinet body along its length and is used to seal the opening of the cabinet body. The key feature is that a limiting rod is fixedly installed at the lower end of the cabinet door near the cabinet body. The limiting rod is horizontally positioned. A limiting track is formed at the lower end of the cabinet body along its length. A slider is provided within the limiting track and slides along the length of the limiting track. A limiting rod is rotatably connected to the upper end of the slider. The limiting rod is horizontally positioned. The limiting rod is hinged to the limiting rod. One end of the limiting track along its length is designated as a limiting end. When the slider is at the limiting end, the limiting rod and the limiting rod are on the same straight line, at which point the cabinet door is at its maximum opening angle.

[0008] By adopting the above technical solution, the cabinet door is used to seal the opening of the cabinet. When the cabinet door is opened, the slider slides along the length of the limiting track, and the limiting rod 2 rotates with the slider, causing the included angle between the limiting rod 1 and the limiting rod 2 to increase. When the slider slides to the limiting end, the limiting rod 1 and the limiting rod 2 are on the same straight line, and the cabinet door opening is at its maximum opening, thereby limiting the cabinet door and improving the stability of the cabinet door opening and closing.

[0009] Optionally, a connector 1 is fixedly installed on one side of the cabinet interior along the length direction, and a connector 2 is fixedly installed on the side of the cabinet door near the cabinet body. A limiting band is provided between connector 1 and connector 2, and the two ends of the limiting band are fixedly connected to connector 1 and connector 2 respectively.

[0010] By adopting the above technical solution, when the cabinet door is opened, connector one and connector two are far apart from each other. When the cabinet door is at its maximum opening angle, the limiting band is in a taut state, which further improves the stability of the cabinet door opening and closing.

[0011] Optionally, a circular limiting groove is provided on the lower end of the cabinet near the cabinet door, and the circular limiting groove is connected to the limiting track.

[0012] By adopting the above technical solution, when the cabinet door is opened, the slider moves along the length of the limiting track, and the circular limiting groove can lock the slider at the end of the limiting track to limit the second limiting rod, thereby limiting the cabinet door and improving the stability of the cabinet door opening process.

[0013] Optionally, a load-bearing rod is fixedly provided on the side of the lower end of the cabinet door near the limiting rod. The load-bearing rod is horizontally set, and a load-bearing wheel is rotatably connected to the end of the load-bearing rod away from the cabinet door. The load-bearing wheel is set vertically, and when the cabinet door is closed, the load-bearing wheel abuts against the inside of the cabinet.

[0014] By adopting the above technical solution, when the cabinet door is closed, the load-bearing rollers roll in close contact with the inside of the cabinet, which helps to reduce the closing speed of the cabinet door. The load-bearing rods and load-bearing rollers are located at the lower end of the cabinet body to support the cabinet door, which improves the stability of the cabinet door closing.

[0015] Optionally, a spring telescopic rod is hinged to the lower end of the cabinet door. The spring telescopic rod is horizontally positioned between the first limiting rod and the cabinet door. The other end of the spring telescopic rod is hinged to the connection between the first limiting rod and the second limiting rod, and is used to move the second limiting rod away from the cabinet body.

[0016] By adopting the above technical solution, when the cabinet door is closed, limit rod one and limit rod two are on the same straight line, and the spring telescopic rod is used to move limit rod two away from the cabinet body, which helps to improve the convenience of closing the cabinet door.

[0017] Optionally, a positioning component 1 is provided on one side of the cabinet along its length. Positioning component 1 is vertically positioned and located on the outside of the cabinet. A positioning component 2 is slidably connected to the side of the cabinet door near the cabinet. Positioning component 2 is vertically positioned and slides along the length of the cabinet door. A number of protrusions are provided at the end of positioning component 2 away from the cabinet door. The protrusions are vertically positioned. When the cabinet door is at its maximum opening angle, the protrusions engage with the end of positioning component 1 away from the cabinet. Both positioning component 1 and positioning component 2 are made of elastic material.

[0018] By adopting the above technical solution, when the cabinet door is opened to the maximum angle, positioning part one and positioning part two fit together, and the protrusion engages with positioning part two to limit the cabinet door. Positioning part two is made of elastic material. When the cabinet door is closed, the protrusion separates from positioning part two from the end of positioning part two away from the cabinet body, which helps to improve the stability of the cabinet door opening and closing.

[0019] Optionally, a positioning groove is provided on the side of the cabinet away from the cabinet door. The positioning groove is set vertically and located inside the cabinet. When the cabinet door is closed, the load-bearing wheels are located inside the positioning groove.

[0020] By adopting the above technical solution, when the cabinet door is closed, the load-bearing roller is located in the positioning groove, which helps to reduce the probability of the cabinet door opening and improves the stability of the cabinet door opening and closing.

[0021] Optionally, a guide plate is fixed at the lower end of the cabinet door, and the guide plate is inclined from bottom to top along the direction of the load-bearing rod pointing to the load-bearing wheel.

[0022] By adopting the above technical solution, when the cabinet door is lowered, the cabinet door closes, the lower end of the guide plate fits against the cabinet body, and the cabinet body slides along the length of the guide plate, thereby raising the cabinet door to the designated position, which improves the convenience of closing the cabinet door.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the cabinet door is opened, the slider slides along the length of the limiting track. The circular limiting groove can lock the slider at the end of the limiting track, limiting the second limiting rod, thereby limiting the cabinet door and improving the stability of the cabinet door opening process.

[0025] 2. When the cabinet door is closed, limit rod one and limit rod two are on the same straight line. The spring telescopic rod is used to move limit rod two away from the cabinet body, so that limit rod one and limit rod two are not on the same straight line, which helps to improve the convenience of closing the cabinet door.

[0026] 3. When the cabinet door is closed, the load-bearing rollers roll in close contact with the inside of the cabinet, which helps to reduce the closing speed of the cabinet door. The load-bearing rods and load-bearing rollers are located inside the cabinet to support the cabinet door, which helps to reduce the probability of the cabinet door sinking and improves the stability of the cabinet door closing.

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses a cabinet door limiting structure for a cable outlet.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2A cabinet door limiting structure for a cable outlet includes a cabinet door 1 and a cabinet body 2. The cabinet door 1 is rotatably connected to one side of the cabinet body 2 along its length. The cabinet door 1 is used to block the opening of the cabinet body 2. A limiting rod 11 is fixedly provided at the lower end of the cabinet door 1 near the cabinet body 2. The limiting rod 11 is horizontally set. A limiting track 21 is opened at the lower end of the cabinet body 2 along its length. A slider 211 is provided in the limiting track 21. The slider 211 can slide along the length of the limiting track 21. A limiting rod 22 is rotatably connected to the upper end of the slider 211. The limiting rod 11 and the limiting rod 22 are hinged together. The limiting rod 11 and the limiting rod 22 are used to limit the cabinet door 1.

[0038] Reference Figure 1 and Figure 2 A circular limiting groove 212 is provided on the lower end of the cabinet body 2 near the cabinet door 1. The circular limiting groove 212 is connected to the limiting track 21. The circular limiting groove 212 allows the slider 211 to be locked at the end of the limiting track 21, limiting the second limiting rod 22. When the cabinet door 1 is opened, the slider 211 slides along the length of the limiting track 21. The slider 211 drives the first limiting rod 11 and the second limiting rod 22 away from the cabinet body 2. When the slider 211 slides to the circular limiting groove 212, the first limiting rod 11 and the second limiting rod 22 are on the same straight line. At this time, the cabinet door 1 is at its maximum opening angle.

[0039] Reference Figure 1 and Figure 3 A connector 23 is fixedly installed on one side of the cabinet body 2 along the length direction. A connector 12 is fixedly installed on the side of the cabinet door 1 near the cabinet body 2. The connector 23 and the connector 12 are connected by a limiting band 121. When the cabinet door 1 is opened, the connector 23 and the connector 12 move away from each other. When the cabinet door 1 is at its maximum opening angle, the limiting band 121 is in a taut state, which limits the cabinet door 1 and improves the stability of the cabinet door 1 opening process.

[0040] Reference Figure 1 A load-bearing rod 13 is fixedly installed on the side of the lower end of the cabinet door 1 near the limiting rod 11. The load-bearing rod 13 is horizontally set and is used to support the cabinet door 1. The end of the load-bearing rod 13 away from the cabinet door 1 is rotatably connected to a load-bearing wheel 14. The load-bearing wheel 14 is set vertically. When the cabinet door 1 is closed, the lower end of the load-bearing wheel 14 abuts against the lower end of the cabinet body 2, which helps to slow down the closing speed of the cabinet door 1. The load-bearing rod 13 and the load-bearing wheel 14 work together to reduce the probability of the cabinet door 1 sinking and improve the stability of the cabinet door 1 when closing.

[0041] Example 2

[0042] Reference Figure 4 and Figure 5The difference between this embodiment and embodiment 1 is that a positioning member 24 is fixedly provided on one side of the cabinet body 2 along the length direction. The positioning member 24 is arranged vertically and located on the outside of the cabinet body 2. A positioning member 16 is slidably connected to the side of the cabinet door 1 near the cabinet body 2. The positioning member 16 is arranged vertically and slides along the length direction of the cabinet door 1. When the cabinet door 1 is opened, the positioning member 16 fits against the positioning member 24. The positioning member 16 is provided with multiple protrusions 161 along the vertical direction. The protrusions 161 are arranged vertically and engage with the end of the positioning member 24 away from the cabinet body 2 to position the cabinet door 1. The positioning member 16 and the positioning member 24 are made of elastic material. When the cabinet door 1 is closed, the protrusions 161 separate from the positioning member 16 from the end of the positioning member 16 away from the cabinet body 2, which helps to improve the stability of the opening and closing of the cabinet door 1.

[0043] Reference Figure 4 and Figure 6 A spring telescopic rod 15 is hinged to the lower end of the cabinet door 1. The spring telescopic rod 15 is used to move the second limiting rod 22 away from the cabinet body 2. The spring telescopic rod 15 is set horizontally and is located between the first limiting rod 11 and the cabinet door 1. The other end of the spring telescopic rod 15 is hinged to the connection between the first limiting rod 11 and the second limiting rod 22. When the cabinet door 1 is closed, the spring telescopic rod 15 is in a compressed state. The spring telescopic rod 15 can push the second limiting rod 22 away from the cabinet body 2, which helps to improve the convenience of closing the cabinet door 1.

[0044] Reference Figure 4 A positioning groove 25 is provided on the side of the cabinet body 2 away from the cabinet door 1. The positioning groove 25 is used to limit the load-bearing wheel 14. The positioning groove 25 is set vertically and located inside the cabinet body 2. When the cabinet door 1 is closed, the load-bearing wheel 14 is located in the positioning groove 25, which helps to reduce the probability of the cabinet door 1 being opened and improves the stability of the cabinet door 1 being closed.

[0045] Reference Figure 4 A guide plate 17 is fixed at the lower end of the cabinet door 1. The guide plate 17 is inclined from bottom to top along the direction of the load-bearing rod 13 pointing to the load-bearing wheel 14. When the cabinet door 1 sinks, the lower end of the guide plate 17 fits against the inside of the cabinet body 2, and the cabinet body 2 slides along the length of the guide plate 17, thereby raising the cabinet door 1 to the designated position and improving the stability of the cabinet door 1 when closing.

[0046] The implementation principle of the cabinet door limiting structure of the present application embodiment is as follows: When the cabinet door 1 is opened, the slider 211 slides along the limiting track 21. When the slider 211 is located in the circular limiting groove 212, the slider 211 is stuck at the end of the limiting track 21, thereby limiting the second limiting rod 22. When the first limiting rod 11 and the second limiting rod 22 are on the same straight line, the cabinet door 1 is at the maximum opening angle. When the cabinet door 1 is closed, the load-bearing wheel 14 rolls against the lower end of the cabinet body 2, which helps to reduce the closing speed of the cabinet door 1. The load-bearing rod 13 and the load-bearing wheel 14 are located inside the cabinet body 2 to support the cabinet door 1, thereby improving the stability of the opening and closing of the cabinet door 1.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
