[0003] A bus bridge with the application number CN201711115638.X includes an outer tube. An inner tube is arranged inside the outer tube. The right side of the inner tube penetrates to the outside of the outer tube. The left side of the bottom of the inner tube is slidably connected to the inner wall of the outer tube. A shell is fixedly connected to the right side of the top of the outer tube. A movable column penetrates through the top of the front of the shell, and a connecting rod is fixedly connected to the front of the movable column. By using the cooperation of the outer tube, inner tube, shell, movable column, connecting rod, handle, limit block, groove, cam, support, movable plate, first fixing block, support rod, baffle, spring, second fixing block, connecting plate, clamping rod and clamping groove, the existing bus bridges are all fixed types. When installing a bus bridge, it is often impossible to install due to inappropriate length dimensions. This bus bridge has the advantage of adjustable length, which facilitates the installation of users and improves the practicability of the existing bus bridges.

[0004] However, the bus of this device is exposed on the outer surface of the bridge. In outdoor rainy weather, rainwater is likely to accumulate inside the bridge, which may cause the accumulated rainwater to corrode the outer surface of the bus. The rainwater may even erode into the inner side of the bus, causing a leakage phenomenon.

[0005] In view of the above problems, it is urgent to innovate and design on the basis of the original bus bridge structure. Content of the Utility Model

[0006] The purpose of the utility model is to provide a bus bridge to solve the problem that the bus of the device is exposed on the outer surface of the bridge. In outdoor rainy weather, rainwater is likely to accumulate inside the bridge, which may cause the accumulated rainwater to corrode the outer surface of the bus. The rainwater may even erode into the inner side of the bus, causing a leakage phenomenon as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A busbar bridge frame, comprising a frame body, on the upper end of which heat dissipation partitions are equidistantly distributed and installed; a first insulating clamping plate, which is arranged between adjacent heat dissipation partitions and is fixedly installed on the upper end of the frame body; a limiting component, which is arranged on the upper end of the frame body; and a rain shielding component, which is arranged on the left and right sides of the limiting component. Among them, by pressing the limiting component, the limiting component and the first insulating clamping plate cooperate with each other to clamp and fix the busbar body; by pressing the limiting component, the rain shielding components on the left and right sides can be driven to turn outwards, and the limiting component can be fixed in the reverse direction by the rain shielding components.

[0008] Preferably, the limiting component includes a baffle plate and a second insulating clamping plate. The baffle plate is arranged on the upper end of the frame body, and a second insulating clamping plate is fixedly installed at the lower end of the baffle plate. The second insulating clamping plate and the first insulating clamping plate are distributed corresponding to each other up and down, and the second insulating clamping plate and the first insulating clamping plate are semicircular in structure when viewed from the front.

[0009] Preferably, the limiting component further includes a guide rod and a first telescopic spring. The guide rod is fixedly installed at the lower end of the baffle plate, and the tail end of the guide rod is nested inside the heat dissipation partition. A first telescopic spring is connected between the heat dissipation partition and the baffle plate.

[0010] Preferably, the left and right sides of the baffle plate are trapezoidal in shape when viewed from the front.

[0011] Preferably, the rain shielding component includes a rain shielding plate, a sliding base and a chute. The rain shielding plate is rotatably connected to the left and right sides of the baffle plate, and a sliding base is rotatably connected to the tail end of the rain shielding plate. The sliding base is nested inside the chute, and the chute is opened on the inner side of the frame body.

[0012] Preferably, the rain shielding component further includes a card slot, a second telescopic spring and a clamping rod. The card slot is opened on the inner side of the sliding base, and a clamping rod is clamped and connected inside the card slot. The clamping rod penetrates through the inner side of the frame body, and a second telescopic spring is connected between the clamping rod and the outer wall of the frame body.

[0013] Preferably, the tail end of the clamping rod is arc-shaped.

[0014] Compared with the prior art, the beneficial effect of the present utility model is that this busbar bridge frame is provided with:

[0015] 1. Fixed structure. When the busbar body needs to be connected to the frame, first insert the head end of the busbar body into the inner side of the frame, and place the bottom of the busbar body on the inner side of the first insulating clamping plate. Then press the baffle downwards. The baffle is subjected to a downward extrusion force, which compresses the first telescopic spring and moves downwards. When the baffle moves downwards, the second insulating clamping plate at its lower end will also move downwards. When it moves down to the second insulating clamping plate fitting against the outer side of the first insulating clamping plate, the busbar body inside is limited and fixed through the cooperation of the second insulating clamping plate and the first insulating clamping plate, so that the busbar body is fixed on the inner side of the frame;

[0016] 2. Rainproof structure. When the baffle moves downwards, it will drive the rainproof plates at both ends to flip outwards, making the rainproof plates at both ends placed at an angle of 45°. This enables rainwater to be drained to both sides of the frame and discharged during rainy days, preventing rainwater from accumulating on the inner side of the frame;

[0017] Furthermore, when the rainproof plate flips outwards, the sliding base at its bottom will slide along the inner side of the chute. When the side end of the sliding base contacts the tail end of the clamping rod, the sliding base will push the clamping rod with an arc-shaped tail end outwards. When the tail end of the clamping rod is flush with the inner side slot of the sliding base, the clamping rod will be reset by the elastic force of the second telescopic spring, so that the tail end of the clamping rod is snap-fitted and connected inside the slot. Through the snap-fitting of the slot and the tail end of the clamping rod, the rainproof plate and the baffle are fixed;

[0018] Furthermore, the upper end of the frame isolates the busbar body through multiple groups of heat dissipation partitions, thus avoiding electromagnetic interference between the busbar bodies. And heat dissipation holes are provided inside the heat dissipation partitions, through which the heat dissipation effect inside the frame can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: a busbar bridge, including:

[0028] Embodiment 1: As Figures 1-4 shown in the technical solution, the present invention provides a technical solution: a busbar bridge, which discloses: a frame body 1, and heat dissipation partition boards 2 are equidistantly distributed and installed at the upper end of the frame body 1; a first insulating clamping plate 3, the first insulating clamping plate 3 is arranged between adjacent heat dissipation partition boards 2, and the first insulating clamping plate 3 is fixedly installed at the upper end of the frame body 1; a limiting component 4, the limiting component 4 is arranged at the upper end of the frame body 1; a rain shielding component 5, the rain shielding component 5 is arranged on the left and right sides of the limiting component 4. Among them, by pressing the limiting component 4, the limiting component 4 and the first insulating clamping plate 3 cooperate with each other to clamp and fix the busbar body; by pressing the limiting component 4, the rain shielding components 5 on the left and right sides can be driven to turn outwards, and the rain shielding component 5 is used to fix the limiting component 4 in the reverse direction;

[0029] The limiting component 4 includes a baffle plate 401 and a second insulating clamping plate 402. The baffle plate 401 is arranged at the upper end of the frame body 1, and the second insulating clamping plate 402 is fixedly installed at the lower end of the baffle plate 401. The second insulating clamping plate 402 and the first insulating clamping plate 3 are distributed up and down corresponding to each other, and the second insulating clamping plate 402 and the first insulating clamping plate 3 are semi-circular in structure when viewed frontally; the limiting component 4 further includes a guide rod 403 and a first telescopic spring 404. The guide rod 403 is fixedly installed at the lower end of the baffle plate 401, and the tail end of the guide rod 403 is nested inside the heat dissipation partition board 2. A first telescopic spring 404 is connected between the heat dissipation partition board 2 and the baffle plate 401; the left and right sides of the baffle plate 401 are trapezoidal in shape when viewed frontally;

[0030] When this structure needs to connect the busbar body to the frame 1, first insert the head end of the busbar body into the inner side of the frame 1, and place the bottom of the busbar body on the inner side of the first insulating clamping plate 3. Then press down the baffle 401. The baffle 401 is subjected to a downward extrusion force, so as to compress the first telescopic spring 404 and move downward. When the baffle 401 moves downward, the second insulating clamping plate 402 at its lower end will also move downward accordingly. It moves downward until the second insulating clamping plate 402 fits against the outer side of the first insulating clamping plate 3. Thus, the busbar body inside is limited and fixed through the cooperation of the second insulating clamping plate 402 and the first insulating clamping plate 3, so that the busbar body is fixed inside the frame 1. And the upper end of the frame 1 isolates the busbar body through multiple groups of heat dissipation partitions 2, so as to avoid electromagnetic interference between the busbar bodies. And heat dissipation holes are provided inside the heat dissipation partitions 2, and the heat dissipation effect inside the frame 1 can be improved through the heat dissipation holes.

[0031] Embodiment 2: As Figures 1-2 , Figures 5-6 shown in the technical solution, the present utility model provides a technical solution: a busbar bridge, which discloses that: the rain shielding assembly 5 includes a rain shielding plate 501, a sliding base 502 and a chute 503. The rain shielding plate 501 is rotatably connected to the left and right sides of the baffle 401, and the tail end of the rain shielding plate 501 is rotatably connected to the sliding base 502. The sliding base 502 is nested inside the chute 503, and the chute 503 is opened on the inner side of the frame 1; the rain shielding assembly 5 further includes a card slot 504, a second telescopic spring 505 and a clamping rod 506.

[0032] When the baffle 401 moves downward in this structure, it will drive the rain shielding plates 501 at both ends to flip outwards, so that the rain shielding plates 501 at both ends are placed at an angle of 45°, so that rainwater can be drained to both sides of the frame 1 and discharged on rainy days, avoiding rainwater accumulation inside the frame 1. When the rain shielding plate 501 flips outwards, the sliding base 502 at its bottom will slide along the inner side of the chute 503. When the side end of the sliding base 502 contacts the tail end of the clamping rod 506, the sliding base 502 will push the clamping rod 506 with an arc-shaped tail end outwards. When the tail end of the clamping rod 506 is flush with the card slot 504 inside the sliding base 502, the clamping rod 506 will be reset by the elastic force of the second telescopic spring 505, so that the tail end of the clamping rod 506 is snap-fitted inside the card slot 504. Through the snap-fitting of the card slot 504 and the tail end of the clamping rod 506, the rain shielding plate 501 and the baffle 401 are fixed.
