Detailed Description

The utility model is further described with reference to the following figures and embodiments.

Example 1:

referring to fig. 1 and fig. 2, in an embodiment of the present invention, an LED power supply for facilitating maintenance includes: the base comprises a base 1 and an upper cover 2, wherein four limit pins 3 are installed on the base 1, four limit holes 4 are formed in the upper cover 2, and the four limit pins 3 are driven by two linkage mechanisms.

In this embodiment, 2 locks of upper cover are on base 1, and spacer pin 3 is just to spacing hole 4 positions, through the ejecting entering spacing hole 4 of link gear drive spacer pin 3, accomplishes the lock of base 1 and upper cover 2 and dies, when needing to open, withdraws spacer pin 3 to the reset position through link gear, can open upper cover 2 fast, and the operation is swift convenient, exempts from the screw design simultaneously, reduces the damage of using the screwdriver to the shell.

Example 2:

as shown in fig. 2, the linkage mechanism includes a mounting groove 5, the mounting groove 5 is opened at the bottom of the base 1, two turntables 7 are rotatably mounted in the mounting groove 5, the turntables 7 and the corresponding limit pins 3 are rotatably mounted with connecting rods 6, and the turntables 7 are both provided with handles 9.
