[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figs. 1 to 4 As shown, the detachable support frame includes two bases 1, which are arranged opposite to each other. The front and rear ends of each base 1 are provided with fixing posts that cooperate with the top cover. A fixing member 11 is provided in the middle of the base 1. The fixing member 11 is provided with two slots 111 that are opposite to each other. The outer side of each slot 111 is provided with an opening 112, and the middle of each slot is provided with an isolation block that separates the slots 111 from left to right.

[0016] The fastener 11 is provided with a locking structure 2 for fixing the support frame 3. The locking structure 2 includes a locking member 21 and a connecting member 22 that cooperate with each other. The locking member 21 has a notch 213 in the middle and inverted U-shaped structures at both ends. Two elastic buckles 211 that are folded upward and cooperate with the slot 111 are respectively provided on the lower side of both ends. The upper ends of the two elastic buckles 211 at the same end are connected to protrusions 212. The elastic buckles 211 of the locking member 21 can enter the slot 111 and abut against the top of the inner wall of the opening 112. Pressing the protrusions 212 inward will cause the buckles 211 to leave the opening 112, and the locking member 21 can be removed from the fastener 11.

[0017] The connecting piece 22 comprises a connecting table 221 in the middle and rotating shafts 222 on both sides, the rotating shafts 222 on both sides of the connecting piece 22 are matched with the inverted U-shaped structures at both ends of the clamping piece 21, and the connecting table 221 is matched with the notch 213; the middle of the connecting table 221 is provided with a mounting hole, and the mounting hole is provided with protrusions on both sides; both ends of the support frame 3 are provided with first through holes 31 opposite to the mounting hole, and second through holes 32 matched with the protrusions are arranged on both sides of the first through holes 31.

[0018] During assembly, the connecting piece 22 passes through the bottom end of the clamping piece 21 to enter the inside of the clamping piece 21, the rotating shafts 222 are matched with the inverted U-shaped structures at both ends of the clamping piece 21, the connecting table 221 is matched with the notch 213 and exposed outside, the protrusions of the connecting table 221 are matched with the second through holes 32 on the support frame 3, and both ends of the support frame 3 are fixed on the connecting table 221 by means of screws passing through the first through holes 31 and the mounting hole; after assembly, the bottom end of the support frame 3 abuts against the upper end of the clamping piece 21; the clamping structure 2 can be matched with the fixing piece 11, so that the support frame 3 is detachably fixed on the base 1, which is convenient for workers to install elements on the support frame 3 and then fix the support frame 3 on the base of the switch box, and the installation is convenient and safe; since the rotating shafts 222 of the connecting piece 22 are matched with the inverted U-shaped structures of the clamping piece 21, when one end of the support frame 3 is not fixed or the one end of the support frame 3 is away from the fixing piece 11, the support frame 3 can rotate around the clamping piece 21, which is convenient for workers to work.

[0019] The detachable support frame of the utility model can be detachably fixed on the base 1 by the clamping structure 2, workers can install elements and circuits first and then fix them on the switch box during construction, and the installation is convenient and safe; and since the rotating shafts 222 of the connecting piece 22 are matched with the inverted U-shaped structures of the clamping piece 21, when one end of the support frame 3 is away from the fixing piece 11, the support frame 3 can rotate around the clamping piece 21, which is convenient for workers to work.
