Description

Technical Field

[0001] The present application relates to the technical field of cable distribution boxes, and particularly relates to a box-type cable distribution box. Background Art

[0002] A cable distribution box is a central component used for connecting cables to cables or cables to other electrical devices. Cable distribution boxes are widely used in commercial centers, industrial parks, urban residential communities, and a large number of urban power grid renovation projects.

[0003] In related technologies, a cable distribution box includes a box body and a box door. The box door is rotatably connected to the box body. A cabinet is provided inside the box body, and electrical components are provided inside the cabinet. The electrical components are used to implement the basic functions of the cable distribution box. A display screen is provided on the cabinet, and the display screen is used to control the electrical components.

[0004] The display screen in the cable distribution box is in a continuously started state. Coupled with the overall high heat inside the cable distribution box, the display screen is continuously started and in a relatively hot environment, which reduces the service life of the display screen and affects the normal use of the display screen. Summary of the Invention

[0005] In order to improve the problem of the relatively low service life of the display screen, the present application provides a box-type cable distribution box.

[0006] A box-type cable distribution box provided by the present application adopts the following technical solutions: A box-type cable distribution box includes a box body and a box door. The box door is rotatably connected to the box body. A cabinet is provided inside the box body, and a display screen is provided on the cabinet. An observation port for viewing the display screen is opened on the box door. An induction device for sensing a human body is provided inside the cabinet, and a photometric detection sensor is provided inside the cabinet; when the induction device senses a human body and the photometric detection sensor detects light, the display screen is started; when the induction device does not sense a human body or the photometric detection sensor does not detect light, the display screen is turned off.

[0007] By adopting the above technical solutions, the staff can observe the display screen through the observation port. At this time, when the induction device senses someone and the photometric detection sensor can detect light, the induction device and the photometric detection sensor will start the display screen to make the display screen light up, so that the staff can view and operate the display screen; if the induction device does not sense a person or the photometric detection sensor does not detect light, the display screen will be turned off. At this time, the display screen will not be in a working state, so that the display screen can standby and extend the service life of the display screen.

[0008] Optionally, an observation board is rotatably connected at the observation port, and the observation board is used to block the opening of the observation port.

[0009] By adopting the above technical solution, the observation port is blocked by the observation plate, so that the observation port can be temporarily closed, preventing external personnel from operating the display screen and reducing the possibility of others being able to operate the display screen.

[0010] Optionally, the cabinet door includes a first rotating door, a second rotating door and a third rotating door. The first rotating door is rotatably connected to the second rotating door, the second rotating door is rotatably connected to the third rotating door, and the third rotating door is rotatably connected to the cabinet body.

[0011] By adopting the above technical solution, since the first rotating door is rotatably connected to the second rotating door, the second rotating door is rotatably connected to the third rotating door, and the third rotating door is rotatably connected to the cabinet body, the staff can fold the first rotating door onto the second rotating door, then fold the second rotating door onto the third rotating door, and finally rotate the third rotating door, reducing the space occupied by the unfolded cabinet door, so that the cabinet door can be used in a small area, enhancing the applicability of the cable distribution box.

[0012] Optionally, a fixing strip is slidably connected to the first rotating door, and a fixing groove for inserting the fixing strip is formed on the second rotating door; when the fixing strip is inserted into the fixing groove, the first rotating door is fixed to the second rotating door.

[0013] By adopting the above technical solution, when the fixing strip is inserted into the fixing groove, the groove wall of the fixing groove limits the fixing strip, so that the first rotating door and the second rotating door can be fixed to each other, enabling the first rotating door and the second rotating door to rotate together. When people rotate the first rotating door, it prevents people from folding the first rotating door onto the second rotating door, facilitating people to rotate the first rotating door and the second rotating door at one time.

[0014] Optionally, a linkage strip is slidably connected to the second rotating door, and a groove for inserting the linkage strip is formed on the third rotating door. The linkage strip is located in the insertion path of the fixing strip; when the fixing strip is inserted into the fixing groove, the linkage strip is inserted into the groove.

[0015] By adopting the above technical solution, the staff slides the fixing strip to insert it into the fixing groove. Since the linkage strip is located in the insertion path of the fixing strip, the fixing strip pushes the linkage strip to move, enabling the linkage strip to be inserted into the groove, thereby enabling the linkage strip to fix the second rotating door and the third rotating door to each other, and the fixing strip fixes the first rotating door and the second rotating door to each other, enabling the cabinet door to be opened as a whole, reducing the operation of the staff to open the cabinet door in sequence and lowering the operation difficulty of the staff to open the cabinet door.

[0016] Optionally, a sliding hole is formed in the second rotating door, a sliding bar is slidably connected in the sliding hole, a sliding groove for inserting the sliding bar is formed in the box body, a second magnet is arranged on the sliding bar, and a first magnet is arranged on the fixed bar; when the first rotating door is folded onto the second rotating door, the first magnet adsorbs the second magnet, and at this time the sliding bar disengages from the sliding groove; when the sliding bar is located in the sliding groove, the second rotating door is fixed to the box body.

[0017] By adopting the above technical solution, by sliding the fixed bar to disengage the fixed bar from the fixed groove, then people rotate the first rotating door to fold the first rotating door onto the second rotating door. At this time, the first magnet adsorbs the second magnet, and the first magnet drives the sliding bar to move through the second magnet, so that the sliding bar disengages from the sliding groove, and thus the sliding bar does not limit the second rotating door, enabling the second rotating door to disengage from the box body, so that people can fold the second rotating door onto the third rotating door; by sliding the sliding bar in the sliding hole and inserting the sliding bar into the sliding groove, the groove wall of the sliding groove limits the sliding bar, enabling the second rotating door to be fixed to the box body, so that the second rotating door does not rotate when the first rotating door is folded.

[0018] Optionally, a stop bar is slidably connected to the third rotating door, a stop groove for inserting the stop bar is formed in the box body, a stop block is arranged on the stop bar, and a limiting bar is slidably connected to the box body. The limiting bar is located on the sliding path of the stop block. When the limiting bar abuts against the stop block, the third rotating door is fixed to the box body.

[0019] By adopting the above technical solution, since the limiting bar is located on the sliding path of the stop block, the limiting bar can limit the stop block, enabling the stop bar to be located in the stop groove. At this time, the third rotating door is fixed to the box body, so that it is convenient to fold the second rotating door onto the third rotating door and prevent the third rotating door from rotating during the folding process of the second rotating door; people slide the limiting bar so that the limiting bar is not on the sliding path of the stop block, enabling people to slide the stop bar to disengage the stop bar from the stop groove, and thus the third rotating door can disengage from the box body.

[0020] Optionally, a limiting spring is arranged on the box body, the limiting spring drives the limiting bar to disengage from the stop block, and a through hole for inserting the sliding bar is formed in the limiting bar; when the sliding bar is located in the through hole, the limiting bar abuts against the stop block; when the sliding bar disengages from the through hole, the limiting bar does not abut against the stop block.

[0021] By adopting the above technical solution, with the sliding bar located within the perforation, the sliding bar limits the position-limiting bar, making it difficult for the position-limiting spring to drive the position-limiting bar to move. As a result, the position-limiting bar does not abut against the stop block, so that the position-limiting bar does not limit the stop bar, facilitating people to drive the stop bar out of the stop groove; when the sliding bar disengages from the perforation, the position-limiting spring drives the position-limiting bar to move, causing the position-limiting bar not to abut against the stop bar, enabling people to slide the stop bar and let the stop bar disengage from the stop groove, facilitating the rotation of the third rotating door on the box body.

[0022] Optionally, the stop bar is rotatably connected to the third rotating door. A first receiving groove for the stop bar to insert is provided on the second rotating door. A second receiving groove for the stop block to slide is provided on the first receiving groove. A third receiving groove for the stop block to insert is provided on the second receiving groove, and the third receiving groove does not penetrate through to the second rotating door; when the second rotating door is folded onto the third rotating door, the stop block is located within the third receiving groove, and the second rotating door is fixed to the third rotating door.

[0023] By adopting the above technical solution, people fold the second rotating door onto the third rotating door, causing the stop bar to insert into the first receiving groove and the stop block to insert into the second receiving groove. Then people rotate the stop bar to move the stop block from the second receiving groove to the third receiving groove. Coupled with the fact that the third receiving groove does not penetrate through to the second rotating door, the groove wall of the third receiving groove limits the stop block, enabling the second rotating door and the third rotating door to be fixed to each other and preventing relative rotation between the second rotating door and the third rotating door after folding.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Staff can observe the display screen through the observation port. When the induction device senses someone, the induction device will activate the display screen to light it up, facilitating staff to view and operate the display screen; when the induction device does not sense anyone, the display screen will turn off. At this time, the display screen is not in a working state, enabling the display screen to standby and extending the service life of the display screen.

[0025] 2. By having the sliding bar within the perforation, the sliding bar limits the position-limiting bar, making it difficult for the position-limiting spring to drive the position-limiting bar to move. As a result, the position-limiting bar does not abut against the stop block, so that the position-limiting bar does not limit the stop bar, facilitating people to drive the stop bar out of the stop groove; when the sliding bar disengages from the perforation, the position-limiting spring drives the position-limiting bar to move, causing the position-limiting bar not to abut against the stop bar, enabling people to slide the stop bar and let the stop bar disengage from the stop groove, facilitating the rotation of the third rotating door on the box body.

[0028] The following further elaborates on this application in conjunction with the attached Figures 1-8 drawings.

[0029] Embodiment 1 This embodiment discloses a box-type cable branch box. Referring to Figure 1 , a box-type cable branch box includes a box body 1 and two box doors 2, and the two box doors 2 are rotatably connected to the box body 1.

[0030] Referring to Figure 2, a cabinet 11 is provided inside the box body 1. There are multiple electrical components inside the cabinet 11, and the electrical components can realize the basic functions of the cable branch box. A plurality of display screens 12 are electrically connected to the cabinet 11. The display screens 12 are electrically connected to the electrical components, and the display screens 12 are for staff to operate.

[0031] Refer to Figure 2 , an induction device 13 is fixedly connected inside the cabinet 11. The induction device 13 is an infrared human body induction device 13, and the induction device 13 is electrically connected to the display screen 12. A photometric detection sensor 14 is fixedly connected inside the cabinet 11, and the photometric detection sensor 14 is electrically connected to the display screen 12. When the induction device 13 does not detect a human body and the photometric detection sensor 14 does not detect light, the display screen 12 goes out; when the induction device 13 detects a human body and the photometric detection sensor 14 detects light, the display screen 12 lights up.

[0032] Refer to Figure 2 , a plurality of observation ports 21 are opened on the surface of the box door 2. The observation ports 21 are for staff to directly observe the display screen 12. An observation board 211 is rotatably connected at the observation port 21, and the observation board 211 is used to block the opening of the observation port 21.

[0033] The implementation principle of Embodiment 1 is: People rotate the observation board 211. At this time, people approach the observation port 21, and a flashlight illuminates the display screen 12, so that the display screen 12 is started.

[0034] Embodiment 2 Refer to Figure 3 , the difference between this embodiment and Embodiment 1 is that the box door 2 includes a first rotating door 3, a second rotating door 4 and a third rotating door 5. The first rotating door 3 is rotatably connected to the second rotating door 4, the second rotating door 4 is rotatably connected to the third rotating door 5, and the third rotating door 5 is rotatably connected to the box body 1.

[0035] Refer to Figure 4 , a receiving groove 31 is opened on the outer surface of the first rotating door 3, and the receiving groove 31 penetrates to the side surface of the first rotating door 3 facing the second rotating door 4. A fixing strip 32 is slidably connected in the receiving groove 31. A fixing groove 41 for inserting the fixing strip 32 is opened on the surface of the second rotating door 4, and the fixing groove 41 penetrates to the surface of the second rotating door 4 facing the third rotating door 5. When the fixing strip 32 is inserted into the fixing groove 41, the first rotating door 3 is fixed to the second rotating door 4, that is, the first rotating door 3 cannot be folded towards the second rotating door 4.

[0036] Refer to Figure 5, a linkage groove 42 is formed on the groove wall of the fixed groove 41. A linkage spring 421 is fixedly connected to the groove wall of the linkage groove 42, and a linkage bar 422 is fixedly connected to the end face of the linkage spring 421. The linkage bar 422 slides within the fixed groove 41 and extends along the length direction of the box body 1. A groove 51 is formed on the surface of the third rotating door 5, and the groove 51 is for the insertion of the linkage bar 422. The linkage spring 421 drives the linkage bar 422 to disengage from the groove 51. When the linkage bar 422 is inserted into the groove 51, the second rotating door 4 and the third rotating door 5 are fixed to each other, that is, the second rotating door 4 cannot be folded towards the third rotating door 5. At this time, the linkage spring 421 is in a stretched state. When the linkage bar 422 is completely located within the fixed groove 41, the linkage spring 421 is in a non-loaded state.

[0037] Refer to Figure 5 , when the fixing bar 32 is inserted into the fixed groove 41, the fixing bar 32 pushes the linkage bar 422 to move, causing the linkage bar 422 to be inserted into the groove 51. At this time, the fixing bar 32 limits the first rotating door 3 and the second rotating door 4, and the linkage bar 422 limits the second rotating door 4 and the third rotating door 5, enabling the box door 2 to be opened as a whole.

[0038] Refer to Figure 5 and Figure 6 , a first magnetic attraction groove 321 is formed on the surface of the fixing bar 32, and a first magnet 322 is fixedly connected within the first magnetic attraction groove 321. A third magnetic attraction groove 411 is formed on the groove wall of the fixed groove 41, and a third magnet 412 is fixedly connected within the third magnetic attraction groove 411. The third magnet 412 adsorbs the first magnet 322, and the magnetic force of the third magnet 412 on the first magnet 322 is greater than the acting force of the linkage spring 421 on the linkage bar 422. The third magnet 412 adsorbs the first magnet 322, enabling the fixing bar 32 to be inserted into the fixed groove 41.

[0039] Refer to Figure 6 , a sliding hole 43 is formed on the surface of the second rotating door 4, and a sliding bar 431 is slidably connected within the sliding hole 43. The sliding bar 431 extends along the thickness direction of the second rotating door 4. A second magnetic attraction groove 432 is formed on the surface of the sliding bar 431 facing away from the box body 1, and a second magnet 433 is fixedly connected within the second magnetic attraction groove 432.

[0040] Refer to Figure 4 and Figure 6 , a sliding groove 15 for the insertion of the sliding bar 431 is formed on the surface of the box body 1. That is, when the sliding bar 431 is inserted into the sliding groove 15, the second rotating door 4 is fixed to the box body 1. When the first rotating door 3 is folded onto the second rotating door 4, the first magnet 322 adsorbs the second magnet 433, causing the sliding bar 431 to disengage from the sliding groove 15. At this time, the second rotating door 4 is separated from the box body 1.

[0041] Reference Figure 4 , a through hole 52 is formed on the surface of the third rotating door 5, a stop ring 523 is slidably connected in the through hole 52, and a stop bar 521 is fixedly connected to the stop ring 523. A stop block 522 is fixedly connected to the outer surface of the stop bar 521, and the stop block 522 can be inserted into the through hole 52. A stop groove 151 is formed on the surface of the box body 1, and the stop bar 521 and the stop block 522 are inserted into the stop groove 151. When the stop bar 521 is inserted into the stop groove 151, the third rotating door 5 is fixed to the box body 1.

[0042] Reference Figure 4 , a moving groove 156 communicating with the sliding groove 15 is formed in the box body 1, the moving groove 156 extends along the length direction of the box body 1, and the moving groove 156 communicates with the stop groove 151. A limiting spring 152 is fixedly connected to the groove wall of the moving groove 156, and a limiting bar 153 is fixedly connected to the end surface of the limiting spring 152. The limiting bar 153 can be inserted into the stop groove 151, and the limiting spring 152 drives the limiting bar 153 to be inserted into the stop groove 151. When the limiting bar 153 is located in the stop groove 151, the limiting spring 152 is in a stretched state, and at this time, the limiting bar 153 is located in the moving path of the stop block 522 disengaging from the stop groove 151. When the limiting bar 153 is completely located in the moving groove 156, the limiting spring 152 is in a non-loaded state.

[0043] Reference Figure 6 , a through hole 154 for inserting the sliding bar 431 is formed on the surface of the limiting bar 153, and the sliding bar 431 can be inserted into the moving groove 156. A limiting inclined surface 155 is formed on the hole wall of the through hole 154 far from the limiting spring 152. The distance between the limiting inclined surface 155 and the limiting spring 152 gradually decreases along the direction from the sliding groove 15 to the moving groove 156, and the limiting inclined surface 155 is located on the sliding path of the sliding bar 431. When the sliding bar 431 is located in the through hole 154, the sliding bar 431 drives the limiting bar 153 to move through the limiting inclined surface 155, so that the limiting bar 153 is inserted into the stop groove 151.

[0044] Reference Figure 7 , a first receiving groove 44 is formed on the surface of the second rotating door 4, and a second receiving groove 441 communicating with the first receiving groove 44 is formed on the surface of the second rotating door 4.

The first receiving groove 44 is for inserting the stop bar 521, and both the second receiving groove 441 and the third receiving groove 442 are for inserting the stop block 522.

[0046] Reference Figure 8 As shown in Figure 8 , when the second rotating door 4 is folded onto the third rotating door 5, the stop bar 521 is inserted into the first receiving groove 44, and the stop block 522 is located in the second receiving groove 441. Then, people rotate the stop bar 521 to move the stop block 522 from the second receiving groove 441 to the third receiving groove 442. At this time, the stop block 522 is fixed to the second rotating door 4, and the stop bar 521 realizes the mutual fixation of the second rotating door 4 and the third rotating door 5.

[0047] The implementation principle of Embodiment 2 is as follows: First, the staff slides the fixing bar 32, and the fixing bar 32 disengages from the fixing groove 41. At this time, the linkage spring 421 drives the linkage bar 422 to disengage from the groove 51. Then, the staff folds the first rotating door 3 onto the second rotating door 4. At this time, the first magnet 322 adsorbs the second magnet 433 to realize the mutual fixation of the first rotating door 3 and the second rotating door 4. Then, the sliding bar 431 disengages from the sliding groove 15. At this time, the sliding bar 431 releases the limit on the stop block 522. Then, the staff pulls the stop bar 521 to make the stop bar 521 disengage from the stop groove 151. The staff folds the second rotating door 4 onto the third rotating door 5, inserts the stop bar 521 into the first receiving groove 44, and finally rotates the stop bar 521 to move the stop block 522 from the second receiving groove 441 to the third receiving groove 442 to realize the mutual fixation of the second rotating door 4 and the third rotating door 5.
