Description

Technical Field

[0001] The utility model relates to the technical field of carrier communication, in particular to a carrier communication branch box with a buffer structure. Background Art

[0002] With the development of the cabling process of distribution network, when the independent load with small capacity is distributed more concentratedly, cable branch box can be used to connect multiple branches of cable. Low-voltage cable branch box is an important secondary distribution equipment in the distribution station area. Intelligent low-voltage cable branch box mainly includes: intelligent monitoring terminal, main bus, disconnector, box door travel switch and intelligent residual current operated circuit breaker. The intelligent monitoring terminal is connected to the power cable on the power supply side of the disconnector through the low-voltage power line; the intelligent monitoring terminal is connected to the auxiliary switch and the box door travel switch of the disconnector through the control cable; one end of the main bus is connected to the load side of the disconnector, and the other end of the main bus is connected to at least two intelligent residual current operated circuit breakers; the auxiliary switch of the disconnector is used to indicate the position signal of the disconnector; the box door travel switch is used to indicate the open and closed state of the box door of the intelligent low-voltage cable branch box.

[0003] The patent specification with the announcement number CN218040751U discloses a cable branch box, including a box body, side panels are provided on the left and right sides of the box body, a plurality of second buffer mechanisms are installed between the side panels and the box body, a top plate is provided above the box body, a U-shaped buffer pad is installed on the top surface of the box body, a plurality of dampers are installed on the top surface of the buffer pad, the upper ends of the plurality of dampers are fixedly connected to the top plate, and a plurality of dampers are sleeved with springs. The above utility model provides a top plate, a damper, and a spring, and when gravel falls on the top plate, the plurality of springs and the plurality of dampers will provide buffering for the box body, thereby preventing the box body and the components installed in the box body from being vibrated, and ensuring the normal use of the branch box.

[0004] However, in the implementation of relevant technologies, it was found that a cable branch box of the above design has the following problem: a buffer mechanism is provided on the outside of the cable branch box to reduce the influence of external impact force on the internal parts of the branch box. However, for branch boxes used indoors, the possibility of encountering gravel impact is low, and this cable branch box with an external buffer structure is not applicable. The branch boxes suitable for indoor use are mostly used by personnel for maintenance. When the box door is closed, the vibration generated by the impact of the box door on the branch box body causes the parts inside the box to loosen. In view of this, a carrier communication branch box with a buffer structure is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a carrier communication branch box with a buffer structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a carrier communication branch box with a buffer structure, comprising a branch box body, an inner shell body is installed inside the branch box body, a box door is hinged at the front end of the branch box body, the parts in the carrier communication branch box are installed in the inner shell body, a buffer bracket is provided on the side surface of the box door close to the inner shell body, and a rubber support rod is provided on the surface of the buffer bracket, a support spring is provided on the outer sleeve of the rubber support rod, and a rubber ball is fixed on the end of the rubber support rod, a buffer beam is installed at the front end of the inner shell body, and a buffer bracket is provided on the box door. When the box door is closed, the elastic action between the buffer bracket and the buffer beam is used to mitigate the impact of the impact force on the branch box body.

[0007] As a further description of the above technical solution: both left and right ends of the buffer beam are fixed on the inner wall of the branch box body, and the two groups of buffer beams are parallel to each other, and the buffer beams support the branch box body.

[0008] As a further description of the above technical solution: the positions of the buffer beam and the buffer bracket correspond to each other, and the rubber ball is elastically connected to the box door through a support spring and a rubber support rod. The elastic action of the support spring and the rubber support rod can weaken the force between the buffer bracket and the buffer beam, thereby avoiding the impact force generated by closing the box door affecting the parts in the branch box.

[0009] As a further description of the above technical solution: telescopic rods are provided at the four corners of the inner shell, and connecting springs are provided on the outer sleeve of the telescopic rods. The inner shell is elastically connected to the branch box body through the telescopic rods and the connecting springs. The inner shell can play a buffering role with the branch box body through the telescopic rods and the connecting springs. Even if the branch box body is impacted, it will not directly act on the inner shell.

[0010] As a further description of the above technical solution: mounting brackets are fixedly installed at both ends of the telescopic rod, and the two groups of mounting brackets are elastically connected through the telescopic rod and the connecting spring. The mounting brackets are used to limit the connecting spring, and the telescopic rod elastically supports the connecting spring.

[0011] As a further description of the above technical solution: one group of the mounting brackets is connected to the inner shell by pins, and the other group of the mounting brackets is connected to the branch box body by pins. The diameter of the mounting brackets is larger than the diameter of the telescopic rod. The mounting brackets connected by the pins can make the inner shell swing inside the branch box body, thereby relying on the force opposite to the impact force to offset each other and achieve an anti-collision effect.

[0012] As a further description of the above technical solution: the outer surface of the inner shell is provided with a number of equidistant and evenly distributed buffer air bags, and the buffer air bags are located between the inner shell and the branch box body. The buffer air bags can prevent the inner shell from directly hitting the branch box body, and play a buffering function between the inner shell and the branch box body.

[0013] The utility model has the following beneficial effects:

[0014] The utility model designs a carrier communication branch box with a buffer structure, by arranging a buffer bracket on the inner side of the box door, and arranging a supporting spring and a rubber supporting rod on the buffer bracket. When the box door is closed, the rubber ball on the buffer bracket contacts with the buffer beam, thereby squeezing the supporting spring and the rubber supporting rod. The elastic effect of the supporting spring and the rubber supporting rod is utilized to buffer the impact force generated when the box door is closed and contacts with the branch box body, thereby reducing the influence of the impact force on the branch box body.

[0015] The utility model designs a carrier communication branch box with a buffer structure. An inner shell is arranged inside the branch box body, and the four corners of the inner shell are connected to the branch box body through telescopic rods. Pins are arranged at the connection points. Once the outside of the branch box body is hit, the telescopic rods and connecting springs can be squeezed inward to move the inner shell, avoiding impact on parts on the inner shell, thereby playing a buffering role for the branch box body.

[0022] Reference Figure 1-4The utility model provides a carrier communication branch box with a buffer structure: it includes a branch box body 1, an inner shell 5 is installed inside the branch box body 1, a box door 2 is hinged at the front end of the branch box body 1, and the parts in the carrier communication branch box are installed in the inner shell 5. The parts in the carrier communication branch box include an intelligent monitoring terminal, a main bus, an isolating switch, a box door travel switch and an intelligent residual current operated circuit breaker, etc. A buffer bracket 3 is provided on the surface of the box door 2 close to the inner shell 5, and a rubber support rod 7 is provided on the surface of the buffer bracket 3, a support spring 6 is provided on the outer sleeve of the rubber support rod 7, and a rubber ball 8 is fixed to the end of the rubber support rod 7, a buffer beam 4 is installed at the front end of the inner shell 5, and a buffer bracket 3 is provided on the box door 2. When the box door 2 is closed, the elastic action between the buffer bracket 3 and the buffer beam 4 is used to mitigate the impact of the impact force on the branch box body 1.

[0023] As a further implementation scheme of the above technical scheme: both left and right ends of the buffer beam 4 are fixed on the inner wall of the branch box body 1 , and the two groups of buffer beams 4 are parallel to each other, and the buffer beams 4 support the branch box body 1 .

[0024] As a further implementation scheme of the above technical scheme: the positions of the buffer beam 4 and the buffer bracket 3 correspond to each other, and the rubber ball 8 is elastically connected to the box door 2 through the support spring 6 and the rubber support rod 7. The elastic action of the support spring 6 and the rubber support rod 7 can weaken the force between the buffer bracket 3 and the buffer beam 4, thereby avoiding the impact force generated by closing the box door 2 affecting the parts in the branch box.

[0025] In specific implementation, when the box door 2 is closed, the rubber ball 8 on the buffer bracket 3 and the buffer beam 4 directly contact each other and squeeze the support spring 6 and the rubber support rod 7 inward. After the support spring 6 and the rubber support rod 7 generate an outward force, the elastic action of the support spring 6 and the rubber support rod 7 is utilized to buffer the impact force generated when the box door 2 closes and contacts the branch box body 1, thereby reducing the impact of the impact force on the branch box body 1. A door lock is set on the box door 2 to close the branch box body 1.

[0026] As a further implementation scheme of the above technical scheme: telescopic rods 10 are provided at the four corners of the inner shell 5, and a connecting spring 11 is provided on the outer sleeve of the telescopic rod 10. The inner shell 5 is elastically connected to the branch box body 1 through the telescopic rod 10 and the connecting spring 11. The inner shell 5 can play a buffering role with the branch box body 1 through the telescopic rod 10 and the connecting spring 11. Even if the branch box body 1 is impacted, it will not directly act on the inner shell 5.

[0027] As a further implementation scheme of the above technical scheme: mounting brackets 12 are fixedly installed at both ends of the telescopic rod 10, and two sets of mounting brackets 12 are elastically connected through the telescopic rod 10 and the connecting spring 11. The mounting brackets 12 are used to limit the connecting spring 11, and the telescopic rod 10 elastically supports the connecting spring 11.

[0028] As a further implementation scheme of the above technical scheme: one group of mounting brackets 12 is connected to the inner shell 5 by pins, and the other group of mounting brackets 12 is connected to the branch box body 1 by pins. The diameter of the mounting brackets 12 is larger than the diameter of the telescopic rod 10. The mounting brackets 12 connected by the pins can make the inner shell 5 swing in the branch box body 1, thereby relying on the opposite force to the impact force to offset each other and achieve an anti-collision effect.

[0029] As a further implementation scheme of the above technical scheme: a number of equidistant and evenly distributed buffer airbags 9 are provided on the outer surface of the inner shell 5, and the buffer airbags 9 are located between the inner shell 5 and the branch box body 1. The buffer airbags 9 can prevent the inner shell 5 from directly hitting the branch box body 1, and play a buffering function between the inner shell 5 and the branch box body 1.

[0030] During specific implementation, if the outside of the branch box body 1 is hit, the telescopic rod 10 and the connecting spring 11 will be squeezed inward under the action of the impact force, so that the inner shell 5 moves in the direction of the force and squeezes the telescopic rod 10 and the connecting spring 11 on the other side to avoid impact on the parts on the inner shell 5. The inner shell 5 can shake in the branch box body 1 under the connection of the pins on the mounting bracket 12, and the parts are fixed on the inner shell 5. Even if the branch box body 1 is impacted, it will not directly act on the inner shell 5. After the force is removed, the telescopic rod 10 and the connecting spring 11 will generate a reverse force to reset the inner shell 5, thereby providing a buffer for the branch box body 1.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
