[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Example:

[0021] See also Figure 1-4 , the utility model provides a technical solution of a main-sub-frame connecting piece: comprising a connecting piece body 1, the connecting piece body 1 is composed of a sub-frame connecting piece 4 and an adjusting gasket 5;

[0022] The four sides of the sub-frame connector 4 are provided with mounting holes. The right side of the sub-frame connector 4 is recessed inwards. An adjusting gasket 5 is provided on the left side of the sub-frame connector 4. A waist-shaped hole is provided on the adjusting gasket 5, and the waist-shaped hole is provided through downwards.

[0023] A fixing pin baffle 2 is provided in the inner cavity of the sub-frame connector 4, a fixing pin 6 is screwed to the middle of the fixing pin baffle 2, the left end of the fixing pin 6 passes through the mounting hole and the waist-shaped hole in sequence, and the left end of the fixing pin 6 is clamped in the waist-shaped hole;

[0024] The inner cavity of the sub-frame connector 4 is longitudinally plugged with the main and sub-frame connecting pins 3, which are docked in the front and rear mounting holes and maintain a movable plug-in state;

[0025] The main and auxiliary frame connecting pins 3 are slidably inserted into the inner cavity of the fixed pin baffle 2;

[0026] One end of the main-sub-frame connecting pin 3 is tilted upward;

[0027] The surface of the fixing pin baffle 2 is provided with uniform corrugated grooves;

[0028] The present invention provides a door frame main-sub-frame connecting member that can be adjusted at multiple angles. The connecting member is composed of modular components, and is more convenient to repair and disassemble. The connecting member is not easy to be displaced after installation. Specifically, the connecting member body 1 is composed of a sub-frame connecting member 4. An adjusting gasket 5 is installed on the left side of the sub-frame connecting member 4. A main-sub-frame connecting pin 3 and a fixed pin baffle 2 are arranged in the inner cavity of the sub-frame connecting member 4. The main-sub-frame connecting pin 3 and the fixed pin baffle 2 are fixed as a whole. The fixed pin baffle 2 is slidably installed in the inner cavity of the sub-frame connecting member 4. The fixed pin baffle 2 can be dragged and displaced synchronously by pulling the main-sub-frame connecting pin 3. A fixed pin 6 is screwed through the middle of the fixed pin baffle 2. The fixed pin baffle 2 and the main-sub-frame connecting pin 3 are fixed together by the fixed pin 6, and the end of the fixed pin 6 continues to extend to the left and can be screwed on the door frame.

[0029] By pulling the fixing pin 6, its position on the waist-shaped hole of the adjusting gasket 5 can be adjusted, and the main-sub-frame connecting pin 3 with one end tilted up makes it convenient for fingers to pinch the end during installation, because the main-sub-frame connecting pin 3 is located in the door frame groove during installation, and it is not convenient for fingers to go deep into the groove to operate when dragging; the gap between the main frame and the sub-frame can be adjusted by adjusting the gasket 5 and the fixing pin 6, and the connecting part is equipped with an internal clamping frame, so that the main and sub-frames are fixed more firmly and are not prone to displacement; at the same time, through the relative extension and contraction of the main and sub-frame connecting part 3 and the fixing pin 6, three-dimensional conversion adjustment can be achieved, which is very convenient.
