DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0021] As Figures 1-4As shown, the utility model discloses a kind of mounting bracket of frequency converter convenient to disassemble and install, including the connecting piece one 5 of lug 3 by countersunk head bolt 4 connection and the connecting piece two 6 by locking bolt connection in wall surface, the connecting piece one 5 is inserted into the connecting piece two 6, the connecting piece two 6 includes shelf plate 7, the four corners of the outer side of shelf plate 7 are equipped with a connecting seat 8 respectively, a plug-in slot 9 is opened in connecting seat 8, the outer side of connecting seat 8 middle part is opened with the avoiding opening 10 of the plug-in slot 9 intercommunication, the connecting piece one 5 includes the blocky connecting part one 11 of being inserted into the plug-in slot 9 and the blocky connecting part two 12 of being inserted into the avoiding opening 10. Embodiment one

[0022] In specific use, as Figure 3 As shown, first, four lugs 3 of frequency converter 1 are connected with one connecting piece one 5 respectively by countersunk head bolt 4;Then, connecting piece two 6 is connected to the specified wall surface position by locking bolt;Finally, connecting part one 11 is inserted into plug-in slot 9, so that connecting piece one 5 is inserted into the connecting seat 8 of connecting piece two 6, that is, the hanging of frequency converter 1 is completed, and when disassembling, frequency converter 1 is only needed to be lifted upwards, so that connecting part one 11 is separated from plug-in slot 9, thus, when disassembling, installing and maintaining in later period, disassembling and re-installing become very convenient.
