Background

The inverter is a converter which converts direct current electric energy (batteries and storage batteries) into constant-frequency constant-voltage or frequency-modulation voltage-regulation alternating current (generally 220V, 50Hz sine wave). It is composed of inverter bridge, control logic and filter circuit. The multifunctional electric grinding wheel is widely used for air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVDs (digital video disks), VCDs (video recorders), computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting and the like. In foreign countries, due to the higher popularization rate of automobiles, the inverter can be used for connecting the storage battery to drive electric appliances and various tools to work when going out for work or traveling. The on-board inverter output through the cigarette lighter is of 20W, 40W, 80W, 120W to 150W power specification. And the other larger power inverter power supply is connected to the battery through a connecting wire.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in the figure, the utility model discloses a domestic inverter convenient to installation, include: inverter main part 1, installation are detained 2 and are installed

extension board

3, 2 fixed mounting are detained in the installation install the 1 back of inverter main part, installation extension board 3 fixed mounting is on the wall body, be provided with spacing groove 24 on the installation extension board 3, installation extension board 3 with the installation is detained the mounting groove 21 cooperation in 2, be provided with elastic locking mechanism 22 in the mounting groove 21, elastic locking mechanism 22 is provided with spacing buckle 23 on one side, spacing buckle 23 with spacing groove 24 cooperation.

In this embodiment, the limiting buckle 23 includes an installation seat 231, a buckle arm 232 and a buckle 233, the buckle arm 232 is fixedly connected to the installation seat 231, and the buckle 233 is fixedly installed at the end of the buckle arm 232, and the installation seat 231, the buckle arm 232 and the buckle 233 are integrally formed.

In this embodiment, the mounting seat 231 is fixedly mounted at the bottom of the mounting groove 21 and adjacent to the elastic locking mechanism 22.

In this embodiment, the elastic locking mechanism 22 includes: the locking device comprises a locking seat 25, a spring 222, a locking hook 223 and a sliding groove 224, wherein a first fixing column 225 is fixedly installed at the top end of the locking seat 25, a second fixing column 226 is fixedly installed at the top end of the sliding groove 224, the spring 222 is fixedly installed between the first fixing column 225 and the second fixing column 226, a rotating hole 227 is formed in the bottom end of the locking seat 25, and the locking hook 223 is rotatably connected in the rotating hole 227.

In this embodiment, a Y-shaped stopper 228 is disposed in the sliding groove 224, a Y-shaped groove 229 is disposed at the top end of the Y-shaped stopper 228, and the Y-shaped groove 229 is matched with the end of the locking hook 223.

In this embodiment, spout 224 lateral wall fixed mounting has transmission piece 2241, transmission piece 2241 end is provided with first voussoir 2242, installation extension board 3 lateral wall fixed mounting with first voussoir 2242 matched with second voussoir 2243.

The working principle is as follows:

in the working process, the second wedge 2243 on the mounting support plate 3 pushes the first wedge 2242, the first wedge 2242 drives the transmission block 2241, and the transmission block 2241 drives the sliding groove 224 to move. During the movement of the sliding slot 224, since the locking hook 223 is made of a rigid material, the movement of the sliding slot 224 forces the end of the locking hook 223 to slide along the slide way formed by the Y-shaped stopper 228, and the end of the locking hook 223 is just hooked on the Y-shaped slot 229 at the top end of the Y-shaped stopper 228.
