Technical Field

[0001] The present application belongs to the technical field of power supply equipment manufacturing, and specifically relates to a power supply equipment that is easy to disassemble and install a power box. Background Art

[0002] In traditional laboratory power supply equipment, the power box is mainly installed on the mounting frame by screws, and the screws are screwed upward from the bottom of the mounting plate on the mounting frame for supporting the power box, so that it is convenient to fix the power box and the mounting frame together, and then a ground wire is set on the power box to relieve the static electricity on the power box. However, in different experiments, the power box will be replaced as needed, and the power box has a certain weight. Generally, the power box has 15-20kg, so it is inconvenient to align the screw holes reserved on the power box with the screw holes on the mounting plate. And when replacing the power box, it is not easy to remove it from the mounting plate, mainly because the mounting frame is provided with a multi-layer mounting plate, in which the distance between the upper surface of the mounting plate for installing the power box and the mounting plate of the upper layer is only about 10 cm more than the height of the power box, which makes it very laborious to remove and install the power box from the mounting plate. Therefore, it is necessary to design a new laboratory power supply equipment. Utility Model Content

By setting guide rails and connecting ears, it is possible to facilitate the installation and removal of the power box on the mounting frame, thereby solving the problem that the current power box is very difficult to install and remove on the mounting frame.

[0024] like Figure 1-7As shown, the first embodiment, a power supply device which is easy to disassemble and install a power box, comprises a mounting frame 1 and a power box 2, the mounting frame 1 is provided with a mounting plate 3, the mounting frame 1 and the mounting plate 3 are both conductive, a guide rail 4 is provided on the upper surface of the mounting plate 3, one end of the guide rail 4 is inside the upper surface of the mounting plate 3, and the other end extends from the mounting plate 3 toward the side of the front of the mounting frame 1 to the edge of the mounting plate 3, a slide groove 5 which cooperates with the guide rail 4 is provided on the power box 2, both ends of the slide groove 5 extend to the outside of the power box 2, a connecting ear 13 is provided on the power box 2, a first connecting hole 6 is provided on the connecting ear 13, a second connecting hole 7 which cooperates with the first connecting hole 6 is provided on the mounting plate 3, the guide rail 4 is conductive, and a bolt 8 passes through the first connecting hole 6 and the second connecting hole 7 to lock the power box 2 and the mounting plate 3 together.

[0025] In the present application, when installing the power box 2 on the mounting plate 3, it is only necessary to buckle the slide groove 5 on the power box 2 on the guide rail 4, and then push the power box 2 to the back of the mounting frame 2. After that, when the first connecting hole 6 and the second connecting hole 7 are aligned, the bolt 8 is simultaneously passed through the first connecting hole 6 and the second connecting hole 7 and then locked. It is very convenient. When the power box 2 is located directly above the mounting plate 3, it is not necessary to use the hand to tighten the power box 2, which is more labor-saving. Moreover, since the first connecting hole 6 is provided on the power box 2, when the power box 2 is locked, the bolt does not need to be connected to the power box 2 from the bottom to the top, which is convenient for installation. Among them, since the guide rail 4, the mounting frame 1 and the mounting plate 3 are all conductive, it is convenient to conduct the static electricity on the power box 2 to the ground. There is no need to connect an additional line to conduct static electricity.

[0026] As a preferred method, in order to ensure that the power supply box 2 is stably installed on the mounting plate 3, two guide rails 4 are provided on the mounting plate 3, and the two guide rails 4 are parallel to each other. Two slide grooves 5 are provided on the lower surface of the power supply box 2, and one slide groove 5 cooperates with one guide rail 4. In this way, the two guide rails 4 share the weight of the power supply box 2, and the center of gravity of the power supply box 2 is between the two guide rails 4 during installation.

[0027] As a preferred embodiment, the connecting ear 13 is provided on the lower end of the side wall of the power box 2 parallel to the guide rail 4, and a baffle 9 is provided on the upper surface of the mounting plate 3 on the side of the guide rail 4 facing the back of the mounting frame 1, and the distance between the upper surface of the baffle 9 and the upper surface of the mounting plate 3 is greater than the distance between the upper surface of the guide rail 4 and the upper surface of the mounting plate 3, and when the power box 2 slides on the guide rail 4 to the baffle 9, the first connecting hole 6 is located directly above the second connecting hole 7. After the connecting ear 13 is provided in this way, it is convenient to observe the insertion degree of the bolt 8 when locking, for example, whether it penetrates the first connecting hole 6 and the second connecting hole 7, and it is also convenient to observe the alignment between the first connecting hole 6 and the second connecting hole 7. The baffle 9 is provided so that when the power box 2 contacts the baffle 9, the first connecting hole 6 is automatically aligned with the second connecting hole 7 to prevent the power box 2 from being pushed too far during the process of pushing.

[0028] In the second embodiment, the connecting ear is a long strip 10, which is arranged on the lower surface of the power box 2. The length of the long strip 10 is greater than the width of the power box 2. Both ends of the long strip 10 extend outside the lower surface of the power box 2. The slide 5 is arranged on the side of the long strip 10 facing away from the power box 2. The length line of the slide 5 is perpendicular to the long strip 10. Both ends of the long strip 10 are provided with the first connecting hole 6. The distance between the upper surface of the guide rail 4 and the upper surface of the mounting plate 3 is greater than the depth of the slide 5. The reason for this arrangement is mainly that the bottom wall of the power box 2 is relatively thin, so in order to prevent the slide 5 from occupying the thickness of the bottom wall of the power box 2, the long strip 10 is arranged. At the same time, compared with the connection ear being directly arranged at the lower end of the side wall of the power box 2, the contact surface of the long strip 10 connected with the power box 2 is larger, so it is more solid.

[0029] As a preferred method, a notch 11 is provided between the two ends of the upper surface of the guide rail 4, and the two side walls of the notch 11 are inclined surfaces 12, and the distance between the top ends of the two inclined surfaces 12 is greater than the distance between the bottom ends of the two inclined surfaces 12. When the long strip 10 slides to the notch 11, the first connection hole 6 is located directly above the second connection hole 7. After the notch 11 is provided, it is not necessary to set the baffle 9. When installing the power box 2, it is only necessary to push the power box 2. When the slide 5 slides to the notch 11, the first connection hole 6 and the second connection hole 7 are automatically aligned, which is more convenient. When disassembling the power box 2, the bolt 8 is removed from the first connection hole 6 and the second connection hole 7, and then the power box 2 is pulled until the power box 2 slides to the outside of the mounting plate 3 through the guide rail 4. When the power box is at least partially located above the mounting plate 3, it is not necessary to lift the power box 2 by hand.

[0030] As a preferred embodiment, two long strips 10 are provided on the lower surface of the power box 2, and the two long strips 10 are provided with the slide grooves 5, and two notches 11 are provided on the guide rail 4, and one notch 11 corresponds to one long strip 10. By providing two long strips 10, the power box 2 is more stable after installation.

[0031] As a preferred mode, when the long strip 10 slides to the notch 11, the lower surface of the power box 2 contacts the upper surface of the guide rail 4. After such arrangement, the contact surface of the guide rail 4 of the power box 2 is increased, so that the installation of the power box 2 is more stable.
