Description

Technical Field

[0002] Bus duct is a conductive product made of copper, aluminum busbar and other materials, used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Bus duct can carry larger currents, so it has a wide range of applications.

[0003] The dense bus duct is a bus duct in which the busbars inside are isolated by insulating materials such as mica. Compared with the air-type bus duct that uses air isolation, it has better effects and is more widely used and safer.

However, the more conventional installation of the heat dissipation fins into the interior of the bus duct is generally connected by bolts and other structures, and the installation method is single and not simple and fast enough.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-Figure 9 As an embodiment of the utility model, the dense bus duct that can be equipped with heat dissipation fins includes two upper and lower cover plates 1 and side plates 2 distributed between the upper and lower cover plates 1. The two upper and lower cover plates 1 and the two left and right side plates 2 are surrounded and fixed to form a bus duct shell structure; a notch is opened on the side plate 2, and a fin plate 3 is arranged on the notch, a movable plate 4 is arranged at the bottom of the fin plate 3, and an elastic pushing mechanism is arranged on one side of the fin plate 3;

[0029] The elastic pushing mechanism cooperates with the fin plate 3, and a latch member 17 is provided on one side of the fin plate 3. When the fin plate 3 is pushed into the slot, the movable plate 4 is driven to move; and when the fin plate 3 is fully pushed into the slot, the elastic pushing mechanism pushes the latch member 17 to quickly pass through the side plate 2 and the fin plate 3, clamping the side plate 2 and the fin plate 3.

[0030] When the fin plate 3 is outside the slot of the side plate 2, the elastic pushing mechanism is in an untriggered state. When the fin plate 3 pushes into the slot to squeeze the movable plate 4, the movable plate 4 will move downward. When the movable plate 4 moves downward, the elastic pushing mechanism will slowly store elastic potential energy. When the elastic potential energy reaches a maximum, the elastic pushing mechanism reaches a critical point. When the fin plate 3 is pushed again, the fin plate 3 is completely inserted into the slot. At the same time, the elastic pushing mechanism passes the equilibrium position and quickly pushes the latch 17 through the side plate 2 and the fin plate 3, firmly clamping the fin plate 3 on the side plate 2.

[0031] The bottom of the fin plate 3 is set as an angled surface, and the top of the movable plate 4 is set as a wedge surface matched with the fin plate 3.

[0032] In this embodiment, the device is configured to cooperate with the fin plate 3 and the elastic pushing mechanism, so that it only needs to push the fin plate 3 in the direction of the side plate 2. When the fin plate 3 just enters the groove on the side plate 2, the fin plate 3 uses the angled surface at its bottom to cooperate with the wedge surface at the top of the movable plate 4 to squeeze the movable plate 4 downward, so that the movable plate 4 moves downward, so that the elastic pushing mechanism slowly stores elastic potential energy. When the movable plate 4 reaches a certain downward position, the elastic potential energy inside the elastic pushing mechanism reaches a maximum. If the movable plate 4 slides downward a little more, the elastic pushing mechanism will quickly push the latch member 17 to pass through the side plate 2 and the fin plate 3, thereby completing the rapid clamping connection between the three, so that the fin plate 3 and the side plate 2 can be installed firmly and quickly.

[0033] In this embodiment, the fin plate 3 and the elastic pushing mechanism cooperate with each other, so that the fin plate 3 can be installed quickly and conveniently, and at the same time, stable installation of the structure is achieved in three different directions: front and back, left and right, and up and down, so that the fin plate 3 is firmly installed on the shell of the bus duct.

[0034] As a further solution of the utility model, a strip groove 202 is provided at the bottom of the side panel 2, and the movable panel 4 can slide downward inside the strip groove 202, a connecting rod 6 is provided at the bottom of the movable panel 4 through a connecting plate, an external box 5 is provided on the side of the side panel 2, a through groove 3 501 is provided at the bottom of the shell of the external box 5, and the connecting rod 6 can move up and down inside the external box 5.

[0035] In this embodiment, when the fin plate 3 presses the movable plate 4 inward, the movable plate 4 slides downward by adapting to the set inclined surface. The movable plate 4 is connected to the bottom of the connecting rod 6 through the connecting plate, so that the movable plate 4 can slide downward while driving the connecting rod 6 to move downward synchronously.

[0036] As a further solution of the utility model, a connecting rod 2 7 is rotatably provided at the top of the connecting rod 1 6, the elastic pushing mechanism includes an eccentric disk 8, one end of the connecting rod 2 7 away from the connecting rod 1 6 is rotatably connected to the eccentric disk 8, and a rotating shaft 1 9 is provided on the inner wall of the external box 5, and the eccentric disk 8 is rotatably connected to the rotating shaft 1 9;

[0037] A circular shaft 10 is arranged on the inner wall of the external box body 5, and the circular shaft 10 is positioned below the eccentric disk 8, a circular shaft 2 12 is arranged on the front edge surface of the eccentric disk 8 away from the circular shaft 10, and a tension spring 11 is arranged between the circular shaft 10 and the circular shaft 2 12, and both ends of the tension spring 11 are respectively hung on the circular shaft 10 and the circular shaft 2 12, and the tension spring 11 is in a stretched state between the circular shaft 10 and the circular shaft 2 12.

[0038] In this embodiment, when connecting rod 1 6 slides downward, connecting rod 1 6 will pull connecting rod 2 7 to move downward, and connecting rod 2 7 will drive eccentric disk 8 to rotate in the direction of connecting rod 1 9 through the rotational connection with eccentric disk 8, that is, the clockwise direction shown in the figure; when eccentric disk 8 rotates in the clockwise direction, the axes of circular shaft 2 12, rotating shaft 1 9 and circular shaft 10 will slowly rotate to the same straight line. When the axes of the three are in the same straight line, the elastic potential energy of the tension spring 11 reaches the maximum. When connecting rod 1 6 continues to move downward with connecting rod 2 7, the eccentric disk 8 will quickly rotate clockwise to the side away from the initial state under the resetting force of the tension spring 11.

[0039] As a further solution of the utility model, a rotating shaft 2 13 is arranged on the inner wall of the external box body 5 relative to the circular axis 10, a swing arm 14 is rotatably arranged on the rotating shaft 2 13, a circular axis 3 15 is arranged at one end of the swing arm 14, and a small roller 16 is rotatably arranged at the circular axis 3 15, when the elastic potential energy of the tension spring 11 reaches a maximum, the edge of the eccentric disk 8 is tangent to the surface of the small roller 16.

[0040] In this embodiment, when the eccentric disk 8 rapidly rotates clockwise to the side away from the initial state under the restoring force of the tension spring 11, the long handle end of the eccentric disk 8 pushes the small roller 16 clockwise, and the small roller 16 pushes the swing arm 14 to rotate in the opposite direction (i.e., the counterclockwise direction shown in the figure) around the rotating shaft 2 13. At this time, the swing arm 14 will rapidly rotate counterclockwise around the rotating shaft 2 13.

[0041] As a further solution of the utility model, a round shaft is rotatably provided on the surface of the swing arm 14, and the round shaft is connected to the latch 17. A slide groove is provided on the side of the latch 17 close to the swing arm 14, and the round shaft is slidably engaged in the slide groove.

[0042] In this embodiment, a circular shaft is provided on the surface of the swing arm 14, and the circular shaft follows the swing arm 14 to make circular motion. At this time, the circular shaft converts its own circular motion into linear motion of the latch member 17 through a slide groove provided at one end of the latch member 17, so that the latch member 17 moves quickly to the side close to the side panel 2.

[0043] As a further solution of the utility model, a through slot 201 is provided on the side of the side panel 2 close to the external box body 5, and the position of the through slot 201 on the side panel 2 is adapted to the latch member 17, and a through slot 2 301 is provided on the side of the fin plate 3 close to the external box body 5, and when the latch member 17 is fully installed in the slot, the through slot 1 201, the through slot 2 301, and the latch member 17 are in the same horizontal space.

[0044] In this embodiment, the latch member 17 is arranged inside the through slot 1 201 in the initial state (the fin plate 3 is not installed), and the latch member 17 is limited by the through slot 1 201. When the latch member 17 is pushed by the elastic pushing mechanism, the latch member 17 will quickly enter the through slot 2 301 on the fin plate 3 from the inside of the through slot 1 201. At this time, the side panel 2 and the fin plate 3 are clamped together by the latch member 17, so that the side panel 2 and the fin plate 3 are stabilized in the front and back, left and right, and up and down directions, thereby achieving the purpose of quickly installing the heat dissipating fin plate inside the bus duct.

[0045] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
