It can be appreciated that, the to-be-fixed member 200 is also provided with a first matching portion and a second matching portion that are respectively matched with the first fixing position 111 and the second fixing position 121, when the bottom plate 10 is in the pre-assembled state, the first matching portion of the to-be-fixed member 200 can be fixed on the first fixing position 111 first, the second matching portion is movably connected with the second fixing position 121, or the first matching portion is movably connected with the first fixing position 111 while the second matching portion is movably connected with the second fixing position 121, and then the first fixing plate 11 and the second fixing plate 12 are controlled to rotate relatively, so that the movably connected first matching portion and the first fixing position 111, and/or the movably connected second matching portion and the second fixing position 121 are mutually buckled, at this time, the first assembling surface 112 and the second assembling surface 122 are coplanar and are attached to one side of the to-be-fixed member 200 facing the bottom plate 10, thereby completing the assembly of the to-be-fixed member 200.

In one embodiment, one of the first fixing portion 111 and the first mating portion may be a protrusion and the other may be a groove, and the other of the second fixing portion 121 and the second mating portion may be a protrusion and the other may be a groove, and when the protrusion is inserted into the groove, the two may not be separated from each other without external action.

Further, when the to-be-fixed member 200 needs to be removed, the first fixing plate 11 and the second fixing plate 12 which are rotatably connected are controlled to rotate relatively, at least one fixing position (at least one of the first fixing position 111 and the second fixing position 121) is separated from the to-be-fixed member 200, and at this time, the to-be-fixed member 200 can be removed from the base plate 10 for maintenance or replacement and other operations.

Thus, the mounting bracket body 100 provided by the application can realize that the mounting and dismounting of the fixing piece 200 are convenient and the operation efficiency can be improved.

Defining that the first fixing plate 11 and the second fixing plate 12 are disposed along the second direction L2, in one embodiment, the first fixing plate 11 may include a plurality of first sub-plates, and a plurality of first support plates are also disposed along the second direction L2 and connected in pairs, where the first sub-plates may be fixedly connected or rotatably connected. Similarly, the second fixing plate 12 may include a plurality of second sub-plates, and the plurality of second sub-plates are also disposed along the second direction L2 and connected in pairs, where the two second sub-plates may be fixedly connected or rotatably connected. The first sub-board and the second sub-board which are connected with each other are in rotary connection, the first fixing position 111 is arranged on any first sub-board, and the second fixing position 121 is fixed on any second sub-board.

In one embodiment, the mounting frame body 100 further includes a locking member 30, where the locking member 30 is used to lock the first fixing plate 11 and the second fixing plate 12 when the base plate 10 is in a fixed state, so that the first fixing plate 11 and the second fixing plate 12 are fixed, and the to-be-fixed member 200 is locked to the base plate 10.

It will be appreciated that the member to be fastened 200 will not be detached from the base plate 10 at this time even if the member to be fastened 200 or the base plate 10 is subjected to force. If the to-be-fixed member 200 needs to be disassembled, the locking state of the locking member 30 is canceled, and then the first fixing plate 11 and the second fixing plate 12 are controlled to be mutually rotated and switched to the preassembled state, at this time, the to-be-fixed member 200 can be removed from the base plate 10.

The plate body at one end of the first fixing plate 11 is directly used as the first fixing position 111, and the plate body at one end of the second fixing plate 12 is used as the second fixing position 121, so that the first fixing plate 11 and the second fixing plate 12 can be in a simple plate-shaped structure without any additional processing. The first mating portion and the second mating portion are both clamping grooves 2011.

First, when the base plate 10 is in the preassembled state, one end of the first fixing plate 11 is clamped in the clamping groove 2011 of the first mating portion, one end of the second fixing plate 12 is aligned with the opening of the clamping groove 2011 of the second mating portion, or one ends of the first fixing plate 11 and the second fixing plate 12 are aligned with the openings of the corresponding clamping grooves 2011, and at this time, the first assembling surface 112 and the second assembling surface 122 form an obtuse angle. Then, the to-be-fixed piece 200 is controlled to force to the side close to the bottom plate 10 so that the second fixing plate 12 is clamped into the clamping groove 2011 of the second matching part, the first fixing plate 11 is clamped into the clamping groove 2011 of the first matching part, and the first fixing plate 11 and the second fixing plate 12 are driven to move mutually until the first assembling surface 112 and the second assembling surface 122 are coplanar, so that the bottom plate 10 is switched to a fixed state.

Further, after the base plate 10 is in a fixed state, the locking member 30 may be fixed at one end to the first fixing plate 11 and at the other end to the second fixing plate 12 to lock the first fixing plate 11 and the second fixing plate 12.

If the to-be-fixed member 200 is required to be removed, at least one end of the locking member 30 is unlocked from the first fixing plate 11 or the second fixing plate 12, and then the first fixing plate 11 and the second fixing plate 12 are controlled to rotate relatively to move the connecting position away from the to-be-fixed member 200 until the first fixing plate 11 and/or the second fixing plate 12 are separated from the clamping groove 2011 of the to-be-fixed member 200, so that the removal is completed.

In one embodiment, the first fixing plate 11 and the second fixing plate 12 may be directly connected in a rotating manner, or a rotating shaft 14 may be disposed between the first fixing plate 11 and the second fixing plate 12, and when the first fixing plate 11 and the second fixing plate 12 are stressed, they may rotate relative to the rotating shaft 14.
