Technical Field

[0001] The utility model relates to the technical field of teaching equipment, in particular to a foldable bridge power supply. Background Art

[0002] With the improvement of teaching quality and teaching requirements, teaching equipment is gradually improved. Especially in laboratories with a wide variety of teaching equipment, various teaching equipment in the laboratory usually needs to be powered on to be used. If each device is connected to a different power supply respectively, it will lead to a complex mess of power cords. Therefore, a suspended bridge power supply is used to provide power for various teaching equipment, and the power cords of various teaching equipment are integrally connected to the suspended bridge power supply, simplifying the routing of the power cords.

[0003] When there is no device that needs to be connected to the bridge power supply through a power cord, although the power cords of the devices can be disconnected and stored through quick connectors or plugs, the bridge power supply still remains in the vertical hanging position, which will not only increase the risk of students bumping into the bridge power supply but also block the students' line of sight, which is not conducive to learning.

[0027] AsFigures 1 to 8 As shown in the figure, this is an embodiment of the present utility model, a foldable bridge power supply, including a hoisting bracket 1 and a power supply bracket 2 arranged on the hoisting bracket 1. The power supply bracket 2 is a hollow cylindrical structure, and a power module 3 is provided at one end of the power supply bracket 2 away from the hoisting bracket 1. A fixing block 4 is also provided on the hoisting bracket 1. The power supply bracket 2 is rotationally connected to the fixing block 4 through a rotating assembly. The fixing block 4 is provided with a rotating groove 5 for the power supply bracket 2 to extend into. The lower end surface of the hoisting bracket 1 is parallel to the horizontal plane. The inner wall of the rotating groove 5 is provided with a blocking surface 6 perpendicular to the lower end surface of the hoisting bracket 1. The power supply bracket 2 has a first position where the side wall abuts against the blocking surface 6 and a second position where the side wall abuts against the lower end surface of the hoisting bracket 1.

[0028] The beneficial effects of such a setting are as follows. The bridge power supply of the present utility model can be rotated through the rotating assembly and the power module is used for the electrical connection of the device. When there is no device that needs to connect to the power supply, the power supply bracket is rotated to the second position where it abuts against the hoisting bracket, that is, the vertically suspended power supply bracket is rotated to a horizontal position parallel to the hoisting bracket, which can not only prevent students from bumping into the power supply bracket but also will not block the students' line of sight, providing a better learning environment.

[0029] Further setting, there are a pair of the rotating assemblies and they are symmetrically distributed on both sides of the power supply bracket 2. The rotating assembly includes a fixing piece 7 and a first rotating piece 8. The first rotating piece 8 is fixedly connected to the inner wall of the power supply bracket 2. One end of the fixing piece 7 is connected to the hoisting bracket 1 and the other end is connected with a rotating shaft 9. The rotating shaft 9 passes through the power supply bracket 2 and is rotationally connected to the first rotating piece 8.

[0030] The beneficial effects of such a setting are as follows. The rotating assembly includes a fixing piece connected to the hoisting bracket and a first rotating piece fixedly connected to the power supply bracket. The fixing piece is connected with a rotating shaft that is rotationally connected to the first rotating piece. This structure of rotational connection has good stability, and the rotating assemblies are a pair and symmetrically distributed on both sides of the power supply bracket, with uniform force and smoother rotation.

[0031] Further setting, the rotating assembly further includes a second rotating piece 10. The second rotating piece 10 is located between the fixing piece 7 and the power supply bracket 2, and the second rotating piece 10 is also rotationally connected to the rotating shaft 9. A clamping groove 11 is opened on the outer wall of the power supply bracket 2, and a first clamping part 12 that is clamped with the clamping groove 11 is installed on the second rotating piece 10.

[0032] The beneficial effects of such a setting are as follows. The second rotating piece is clamped with the clamping groove of the power supply bracket through the first clamping part, and the second rotating piece is also rotationally connected to the rotating shaft. The second rotating piece cooperates with the first rotating piece to further improve the stability of the rotational connection of the power supply bracket, and also has the advantages of simple structure and convenient disassembly and assembly.

[0033] Further, the first rotating piece 8 is in an L-shaped structure. One end of the first rotating piece 8 is fixedly connected to the inner wall of the power supply bracket 2, and the other end extends into the hoisting bracket 1 and is fixedly connected to a connecting piece 13. A pin shaft 14 is provided on the connecting piece 13. On one side of the hoisting bracket 1 corresponding to the power supply bracket 2, a cylinder 15 is provided. The cylinder 15 drives a telescopic rod 16 rotatably connected to the pin shaft 14 in the horizontal direction.

[0034] The beneficial effects of such a setting are as follows. The rotation of the power supply bracket is controlled by the cylinder, that is, the telescopic rod is connected to the first rotating piece through the connecting piece. When the telescopic rod retracts, the power supply bracket rotates to the first position. When the telescopic rod extends, the power supply bracket rotates to the second position. The rotation is controlled electrically, saving manpower and enabling the power supply bracket to be maintained at a specific position.

[0035] Further, an installation block 17 and a connecting block 18 fixedly connected to the cylinder 15 are further provided inside the hoisting bracket 1. A strip-shaped groove 19 is further provided on the connecting block 18. A second clamping member 20 penetrating the strip-shaped groove 19 is connected to the installation block 17.

[0036] The beneficial effects of such a setting are as follows. The position of the cylinder can be finely adjusted by adjusting the connection position between the connecting block and the installation block. The installation block is connected to the strip-shaped groove of the connecting block through the second clamping member, and the connecting block can slide along the direction of the strip-shaped groove, ensuring that the cylinder can control the rotation of the power supply bracket in place.

[0037] Further, an installation assembly is further provided inside the hoisting bracket 1. The installation assembly is a pair and is symmetrically distributed on both sides of the power supply bracket 2. The installation assembly includes an installation beam 21 and a slider 22.

Both the fixing piece 7 and the installation block 17 are fixedly connected to the slider 22.

[0038] The beneficial effects of such a setting are as follows. Both the fixing piece of the rotating assembly and the installation block connecting the cylinder are fixedly connected to the slider of the installation assembly. The slider can slide along the chute of the installation beam, enabling the cylinder and the power supply bracket to move and adjust the position synchronously, and improving the overall structural consistency and connection strength through the installation assembly.

[0039] Further, at least one wire routing groove 24 is provided on the inner wall of the power supply bracket 2. An opening is provided on the side wall of the wire routing groove 24.

[0040] The beneficial effects of such a setting are as follows. The wire routing groove is used for the power cord to pass through, separating the power cords to prevent them from being wound and intertwined. The opening facilitates pressing the power cord into the wire routing groove.

[0041] Further, a lighting module 25 is also provided on the lower end surface of the hoisting bracket 1.

[0042] The beneficial effects of such a setting are as follows: the lighting function is increased, the functionality of the bridge power supply is enriched, and the power supply bracket does not block the lighting module.
