In order to achieve the above object, the present invention provides a square quick detach mechanism for a camera, comprising:

a rectangular placing groove is formed in the frame body;

the outer frame of the connecting piece is rectangular, the connecting piece is arranged at the opening side of the placing groove, and a plurality of positioning holes which are matched with the fixing piece for fixing are correspondingly formed in the side face of the connecting piece;

the fixing pieces are arranged in a plurality of groups and are arranged on the end face of one side of the frame body, provided with the placing grooves, and used for limiting and fixing the connecting pieces.

As a further scheme of the invention, the size specification of the square plate is smaller than the inner frame specification of the rectangular placing groove.

As a further scheme of the invention, the fixing piece is a limiting reed, one ends of a plurality of groups of the compression reeds are rotatably connected to the frame body, and the other ends of the compression reeds are used for extending into the positioning holes on the side surfaces of the connecting pieces to compress the connecting pieces.

As a further proposal of the invention, the end surface of the frame body is provided with a guide groove for placing the compression reed.

Compared with the prior art, the four-group compression reed is arranged on the side face of the frame body, and is rotated to extend into the positioning hole on the side face of the square connecting piece to position and compress the square connecting piece.

In the accompanying drawings: 1. a frame; 101. a placement groove; 102. a guide groove; 2. a connecting piece; 201. positioning holes; 3. and a fixing piece.

Detailed Description

The technical scheme of the invention is further described in detail below with reference to the specific embodiments.

As shown in fig. 1 and fig. 2, in the embodiment of the invention, a square quick disassembling mechanism for a camera comprises a frame 1, wherein a rectangular placing groove 101 is formed in the frame; the outer frame of the connecting piece 2 is rectangular, the connecting piece 2 is arranged on the opening side of the placing groove 101, and a plurality of positioning holes 3201 which are matched with the fixing pieces for fixing are correspondingly formed in the side face of the connecting piece 2; the fixing pieces are arranged in a plurality of groups and are arranged on the end face of one side of the frame body 1, provided with the placement groove 101, and used for limiting and fixing the connecting pieces 2;

the connecting piece 2 is a square plate, the size of the square plate is smaller than the inner frame of the rectangular placing groove 101, so that the square plate can deflect moderately when placed in the rectangular placing groove 101, specifically, the front side of fig. 1 is taken as an example, the square plate can be eccentric by 1 to 10 degrees along the pointer when placed in the placing groove 101, the specific deflection angle can be according to actual shooting requirements, the contact area between the fixing piece and the square plate needs to be correspondingly increased when the deflection angle is larger, and the fixing piece with larger compression coefficient needs to be correspondingly replaced when the mass of the square plate is increased, so that the square plate is fixed.

The four sets of corner parts of the placing groove 101 are respectively provided with a set of fixing pieces, and the four sets of fixing pieces can respectively correspond to the four sets of corner parts of the square plate to finish the fixing of the four sets of corner parts of the square plate.

As shown in fig. 1 and fig. 2, in the embodiment of the present invention, the fixing element is a limiting reed, one end of each of the plurality of groups of pressing reeds is rotatably connected to the frame body 1, and the other end of each of the plurality of groups of pressing reeds is used for extending into a positioning hole 3201 on the side surface of the connecting element 2 to press the square plate, wherein the weight of the square plate is shared by the four groups of pressing reeds, so that the fixing requirement of the square plate is improved;

of course, in actual design, the compressing reed can be adjusted according to the specifications of the square plate in actual situation, for example, when the length specification of a group of side strips of the direction plate is longer, the number of compressing reeds corresponding to the square plate can be increased.

As shown in fig. 1 and fig. 2, in the embodiment of the present invention, a guide groove 102 for placing the compression reed is provided on the end surface of the frame body 1, so that the compression reed does not protrude out of the end surface of the frame body 1, and the problem that the compression reed is scratched and rotated by external force is avoided.

By integrating the above, the invention sets up the multiple groups of compression reeds on the side surface of the frame body 1, rotates the compression reeds, stretches into the positioning holes 3201 on the side surface of the square connecting piece 2, and positions and compresses the compression reeds.
