Description

Technical Field

[0001] The utility model relates to the technical field of digital power-saving switches, in particular to a digital power-saving switch. Background Art

[0002] Digital power-saving switches are used to connect, carry and disconnect currents under normal conditions, and can also connect, carry and disconnect currents under specified abnormal conditions. They are widely used in industries such as factories and mines, high-rise buildings, commercial and household places.

[0003] However, there are some shortcomings in the current power-saving switches. The power-saving switches are equipped with digital display screens and control buttons, but the digital display screens and control buttons are exposed, which are easy to be damaged and will also cause dust to adhere to their surfaces, which is not conducive to the installation and use of the power-saving switches. For this reason, we propose a digital power-saving switch. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised by the above background technology, and the utility model provides a digital power-saving switch.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A digital power-saving switch comprises a shell, a protective cover plate slidably connected to the top of the shell, extrusion plates slidably connected to both ends of the bottom of the protective cover plate, a moving rod slidably connected to the protective cover plate, a moving block connected to the bottom of the moving rod, a connecting block connected to the shell, a limiting groove provided on the connecting block, a limiting block clamped on the inner side of the limiting groove, and the limiting block connected to the moving block.

[0007] Furthermore, both ends of the bottom of the protective cover are connected with sliding plates, and grooves are provided on both sides of the shell, and the opposite sides of the two sliding plates are slidably connected to the inner sides of the two grooves respectively.

[0008] Furthermore, both ends of the protective cover plate are connected to side plates, and a screw is threadedly connected to the side plate. One end of the screw is rotatably connected to the extrusion plate, and the other end of the screw is connected to a turning hand wheel.

[0009] Furthermore, two symmetrically distributed sliding grooves are provided at both ends of the protective cover plate, and sliders are slidably connected to the inner sides of the plurality of sliding grooves, and the two extrusion plates are respectively connected to the corresponding two sliders.

[0010] Furthermore, the protective cover plate is also connected to a fixed block, and the moving rod is slidably connected to the fixed block.

[0011] Furthermore, a spring is sleeved on the top of the moving rod, and a pressure block is also connected to the top of the moving rod. One end of the spring is connected to the pressure block, and the other end of the spring is connected to the fixed block.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model uses a protective cover plate to protect the digital display screen and control buttons on the shell. The protective cover plate can slide on the shell, so that the protective cover plate can be easily slid into or out of the shell. The extrusion plate slides on both ends of the bottom of the protective cover plate to press the extrusion plate against the shell, so as to limit the protective cover plate. The moving rod slides on the protective cover plate to drive the moving block to move, so that the moving block is attached to or separated from the connecting block. When the moving block is attached to the connecting block, the limiting block is clamped with the inner side of the limiting groove, so as to limit the moving block. The moving rod is then limited, and the protective cover is then limited. When the moving block is separated from the connecting block, the limit block is separated from the limit groove, which makes it convenient to disassemble the protective cover, so that the protective cover can adapt to digital energy-saving switches of different sizes, and protect the digital display screen and control buttons of the digital energy-saving switch, thereby solving the problem that the energy-saving switch is provided with a digital display screen and control buttons, but the digital display screen and control buttons are exposed, which are easy to be damaged, and dust will also adhere to the surface, which is not conducive to the installation and use of the energy-saving switch.

In some embodiments, the digital display screen and control buttons on the shell 1 are protected by the protective cover plate 4, and the protective cover plate 4 can slide on the shell 1, so as to facilitate the protective cover plate 4 to slide into or out of the shell 1, and the extrusion plate 7 is slid at both ends of the bottom of the protective cover plate 4, so as to press the extrusion plate 7 against the shell 1, so as to limit the protective cover plate 4, and the moving rod 16 slides on the protective cover 4, thereby driving the moving block 13 to move, so that the moving block 13 and the connecting block 12 are fitted or separated. When the moving block 13 and the connecting block 12 are fitted, the limit block 19 is engaged with the inner side of the limit groove 18, thereby limiting the moving block 13, and then limiting the moving rod 16, and then limiting the protective cover 4. When the moving block 13 is separated from the connecting block 12, the limit block 19 is separated from the limit groove 18, so that it is convenient to disassemble the protective cover 4, so that the protective cover 4 can adapt to digital power-saving switches of different sizes, and protect the digital display screen and control buttons of the digital power-saving switch, thereby solving the problem that the power-saving switch is provided with a digital display screen and control buttons, but the digital display screen and control buttons are exposed, which is easy to be damaged, and dust will also adhere to their surfaces, which is not conducive to the installation and use of the power-saving switch.
