[0001] This utility model relates to the field of power distribution technology, and in particular to a plug-in box. Background Technology

[0002] Currently available plug-in boxes require a large amount of space and have a short travel range for their moving operating mechanism, which prevents the power-collecting copper plug from fully descending into the box, making them prone to accidental damage. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing plug-in boxes, such as the large space required and the small stroke of their moving operating mechanism, which makes it difficult for the power-collecting copper plug to fully descend into the box and easily cause accidental collision damage. This utility model provides a plug-in box.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a plug-in box, including a box body, a power-taking unit disposed in the box body, and a driving component for driving the power-taking unit; the driving component includes a moving component for driving the power-taking unit to move relative to the box body and a guiding component for guiding the power-taking unit, the bottom of the box body has a handle connected to the moving component, and a locking structure for locking the handle is also provided between the handle and the box body.

[0005] Furthermore, the movable component includes a ball-and-socket bracket disposed within the housing, a double-ball-head connecting rod disposed between the ball-and-socket bracket and the power-gathering unit, a lower ball-and-socket disposed on the ball-and-socket bracket, and an upper ball-and-socket disposed at the bottom of the power-gathering unit. The handle is connected to the lower ball-and-socket via a transmission block.

[0006] Furthermore, the transmission block has a fixing part that is fixedly connected to the lower ball socket and a transmission part that passes through the handle. The fixing part is provided with a fixing hole for the locking member to pass through.

[0007] Furthermore, the handle is provided with a transmission hole for the transmission part to be inserted, and both the transmission part and the transmission hole are square.

[0008] Furthermore, the ball socket support is provided with a limiting piece for limiting the rotation angle of the lower ball socket.

[0009] Furthermore, the power supply unit includes a power supply bracket connected to the upper ball socket drive, a plurality of power supply modules disposed on the power supply bracket, and copper plugs disposed on the power supply modules. The housing is provided with a power supply unit for inserting the copper plugs.

[0010] Furthermore, the housing is also provided with a limiting part for limiting the copper plug-in.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] See Figure 1-7 The present invention provides a plug-in box 100, which includes a box body 10, a power-collecting unit 20 disposed in the box body 10, and a driving component for driving the power-collecting unit 20. The driving component includes a moving component 30 for driving the power-collecting unit 20 to move relative to the box body 10 and a guiding component 40 for guiding the power-collecting unit 20. The bottom of the box body 10 has a handle 50 connected to the moving component 30, and a locking structure for locking the handle 50 is also provided between the handle 50 and the box body 10. By rotating the handle 50, the moving component 30 is driven to raise and lower the power-collecting unit 20 relative to the housing 10. This effectively saves internal space while increasing the travel distance of the moving component 30 in raising and lowering the power-collecting unit 20, ensuring that the power-collecting unit 20 is completely housed within the housing 10 and preventing it from being bumped or knocked. Furthermore, by using the guide component 40 to guide the moving component 30 in raising and lowering the power-collecting unit 20 relative to the housing 10, the displacement accuracy of the power-collecting unit 20 during the raising and lowering process can be effectively improved. In addition, by using a locking structure, the operator needs to pull down and rotate the handle 50 to drive the moving component 30 to raise and lower the power-collecting unit 20, thus effectively preventing accidental connection or disconnection of the power-collecting unit 20.

[0019] like Figure 1As shown, the moving component 30 includes a ball-and-socket bracket 31 disposed within the housing 10, a double-ball-head connecting rod 32 disposed between the ball-and-socket bracket 31 and the power-gathering unit 20, a lower ball-and-socket joint 33 disposed on the ball-and-socket bracket 31, and an upper ball-and-socket joint 34 disposed at the bottom of the power-gathering unit 20. The handle 50 is connected to the lower ball-and-socket joint 33 via a transmission block 35. In the embodiment provided by this utility model, by utilizing the double-head connecting rod, the lower ball-and-socket joint 33, and the upper ball-and-socket joint 34 to connect the handle 50 to the power-gathering unit 20, a multi-degree-of-freedom motion effect can be achieved, allowing multi-angle rotation and oscillation on different planes, realizing compound movements such as flexion, extension, and rotation, providing great flexibility, effectively saving internal space while obtaining a large travel distance. In other possible embodiments, specially designed universal joints, such as external ball-cage universal joints and cross-shaft universal joints, can also be used to connect the handle 50 to the power-gathering unit 20.

[0020] And, as Figure 1 As shown, the contact point changes continuously with motion, determined by the geometric contact characteristics of the ball head and socket of the double ball head connecting rod 32. The friction coefficient is low, approximately 0.01 to 0.05. Sliding friction accounts for approximately 10% to 30%, with a friction coefficient of approximately 0.3 to 0.6. This sliding friction originates from the minute relative sliding between the ball head and socket contact surfaces. Compared to the sliding friction of traditional planar pairs, this reduces friction loss, indirectly achieving a labor-saving effect and extending service life. Furthermore, by utilizing the spherical contact surface to distribute the load, local stress concentration is avoided, significantly improving fatigue resistance. The ball head and socket can automatically compensate for off-center loads caused by external impacts, exhibiting excellent impact resistance. This achieves the technical effects of high load-bearing capacity, high fatigue resistance, automatic off-center load compensation, and high impact resistance.

[0021] like Figure 2 and Figure 3 As shown, the transmission block 35 has a fixing part 351 fixedly connected to the lower ball socket 33 and a transmission part 352 that passes through the handle 50. The fixing part 351 is provided with a fixing hole for the locking member 52 to pass through. By using locking members 52 such as bolts, studs, and pins to pass through the fixing hole on the fixing part 351 and lock them in the lower ball socket 33, the stability of the fixed connection between the transmission block 35 and the lower ball socket 33 can be effectively guaranteed, thereby ensuring the stability of the transmission connection between the handle 50 and the lower ball socket 33 through the transmission block 35. The handle 50 provided by this utility model is provided with a transmission hole for the transmission part 352 to be inserted, and in the embodiment provided by this utility model, both the transmission part 352 and the transmission hole are square. By making both the transmission part 352 and the transmission hole square, the stability of the rotating handle 50 driving the transmission block 35 to rotate the lower ball socket 33 can be effectively guaranteed, thereby further ensuring the stability of the transmission connection between the rotating handle 50 and the lower ball socket 33.

[0022] like Figure 1As shown, the ball socket bracket 31 is provided with a limiting piece 311 for limiting the rotation angle of the lower ball socket 33. By using the limiting piece 311, the rotation angle of the lower ball socket 33 driven by the rotary manual drive transmission block 35 can be effectively limited, so that the lower ball socket 33 can only move within a rotation range of 180°. In other possible embodiments, this can be achieved by using two or more double ball joints 32. In this case, the rotation engagement mode of the handle 50 can also be changed to a horizontal linear motion mode to drive the double ball joints 32 to drive the power supply unit 20 to rise and fall relative to the housing 10.

[0023] like Figure 1 and Figure 3 As shown, the power-harvesting unit 20 provided by this utility model includes a power-harvesting bracket 21 that is connected to the upper ball socket 34, a plurality of power-harvesting modules 22 disposed on the power-harvesting bracket 21, and copper inserts 23 disposed on the power-harvesting modules 22. A power supply unit for inserting the copper inserts 23 is provided on the housing 10. By using a limiting piece 311 to limit the rotation range of the lower ball socket 33 to within 180°, when the double ball joint rod 32 rotates to the connection position, the copper insert 23 of the power-harvesting unit 20 completely protrudes outside the housing 10, and the double ball joint rod 32 and the copper insert 23 are in the same direction, i.e., reaching the dead point position of the double ball joint rod 32. This effectively prevents the copper insert 23 from dropping due to its own weight or external impact, making power harvesting more reliable and meeting the high reliability requirements of data center power supply. Furthermore, in the embodiment provided by this utility model, a limiting part 11 for limiting the copper insert 23 is also provided inside the housing 10. By utilizing the limiting part 11, the displacement of the copper plug 23 of the power supply unit 20 relative to the housing 10 during lifting and lowering can be effectively limited, thus preventing the copper plug 23 from being bumped or knocked.

[0024] like Figure 1 As shown, the guide assembly 40 includes several linear bearings 41 fixed on the power supply bracket 21 and several guide shafts 42 slidably connected to the linear bearings 41. The guide shafts 42 are fixed inside the housing 10 by fixing plates 43. By using the linear bearings 41 and guide shafts 42 to guide the power supply unit 20, the guide fit can be more precise, with a fit gap of less than 0.02mm. This effectively avoids the copper plug-in 23 tilting due to a large fit gap, ensuring that the copper plug-in 23 of the power supply unit 20 can be accurately inserted into the power supply unit such as the U-shaped copper busbar. It also makes the force more balanced after insertion, further improving reliability. This achieves the technical effect of precise guide fit of the guide assembly 40 and more reliable power supply performance of the power supply unit 20.

[0025] like Figures 4 to 7As shown, the locking structure includes several locking pins 51 disposed on the handle 50 and several locking holes disposed inside the housing 10 for the locking pins 51 to be inserted. By inserting the locking pins 51 on the handle 50 into the locking holes of the housing 10, the operator needs to pull down and rotate the handle 50 to drive the moving component 30 to move the power supply unit 20 up and down, thereby effectively preventing accidental connection and disconnection of the power supply unit 20. Furthermore, the locking structure also includes a locking member 52 locked within the transmission part 352 of the transmission block 35, and the locking member 52 is provided with a spring 53 for elastically connecting the handle 50 and the housing 10. By fitting the spring 53 onto bolts, studs, or other locking devices and elastically connecting the handle 50 to the housing 10, the locking pin 51 of the handle 50 can be inserted into the locking hole of the housing 10 under the elastic force of the spring 53, thus locking the handle 50. After rotating the handle 50 180°, the operator releases the handle 50, and the locking pin 51 is inserted into the locking hole of the housing 10 under the elastic force of the spring 53, thus locking the handle 50 again. This effectively prevents operator error from causing the connection or disconnection of the power supply unit 20.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
