DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: See Figures 1 to 8 A roller screen with a conveniently removable screen box comprises: a frame 1 on which a screen box 2 is detachably mounted; a connecting mechanism 4 mounted between the frame 1 and the screen box 2 for securing the frame 1 to the screen box 2; and a fixing mechanism 3 mounted on the frame 1 for cooperating with the connecting mechanism 4 to secure the screen box 2 to the frame 1. In this embodiment, a lock body 11 is also mounted on the lower half of the frame 1.

[0028] The working principle of the present invention is as follows: during installation, the fixing mechanism 3 is first moved downward, and then the screen window box 2 and the frame 1 are fixed through the connecting mechanism 4. Subsequently, the fixing mechanism 3 is moved upward to further fix the screen window box 2 and the frame 1 to improve the fixing effect. During disassembly, only the fixing mechanism 3 needs to be moved downward to carry out the disassembly work. The operation is simple, the disassembly of the screen window box 2 is convenient, and it can better meet the use requirements.

[0029] As a further solution, the connecting mechanism 4 includes a connecting groove 41 opened on the frame 1, and a connecting slot 42 is opened at a position corresponding to the connecting slot 41 on the front side of the frame 1, and the connecting slot 42 is connected to the connecting slot 41. A connecting block 43 is installed at a position corresponding to the connecting slot 41 at the lower end of the screen box 2, and the connecting block 43 is inserted in the connecting groove 41. A connecting protrusion 44 is installed on the front side of the connecting block 43 at a position corresponding to the connecting slot 42, and the connecting protrusion 44 is inserted in the connecting slot 42. In this embodiment, the lower end of the connecting block 43 is provided with an arc chamfer.

[0030] The working principle of the connecting mechanism 4 is: when connecting, insert the connecting block 43 into the connecting groove 41. When the connecting protrusion 44 moves to the position of the connecting slot 42, push the connecting block 43 upward so that the connecting protrusion 44 is inserted into the connecting slot 42. The initial fixing work can be completed. The operation is simple and convenient for disassembly.

[0031] As a further solution, the fixing mechanism 3 includes a fixed stopper 31 slidably mounted in the connecting groove 41, a fixed slot 34 is provided on the front side of the fixed stopper 31, a mounting slot 30 is provided on the front side of the frame 1 corresponding to the fixed slot 34, a lifting slider 32 is provided at the position of the mounting slot 30, a fixed insert 33 is installed on the rear side of the lifting slider 32, and the fixed insert 33 is inserted into the fixed slot 34;

[0032] The fixed block 31 is also provided with a pair of positioning grooves 35, and a positioning ball 36 is movably installed on the rear side of the positioning groove 35. A positioning spring 37 is also installed in the middle position of the positioning groove 35, and a positioning end cover 38 is installed on the front side of the positioning groove 35. The two ends of the positioning spring 37 are respectively in contact with the positioning ball 36 and the positioning end cover 38, and the rear side of the positioning ball 36 is in contact with the connecting groove 41. In this embodiment, the inner diameter of the positioning groove 35 gradually increases from the back to the front, and the diameter of the positioning ball 36 is larger than the inner diameter of the rear side of the positioning groove 35.

[0033] As a further solution, an arc-shaped supporting portion 311 is provided at the end of the fixed stopper 31 at a position corresponding to the arc-shaped chamfer.

[0034] By providing the arc-shaped support portion 311, it is convenient to insert the rear side of the connecting plug 43, thereby positioning the connecting plug 43 and preventing it from moving backward, causing the connecting protrusion 44 to disengage from the connecting slot 42, thereby improving the fixing effect.

[0035] The working principle of the fixing mechanism 3 is as follows: after the initial fixing work is completed, the lifting slider 32 is pushed upward, thereby driving the fixing block 31 to move upward, and then the arc-shaped support portion 311 at the end of the fixing block 31 is inserted into the rear side of the connecting plug 43, thereby preventing the connecting plug 43 from moving backward, and the fixing work is completed. By providing a positioning spring 37, the positioning ball 36 can be pushed to contact the connecting groove 41, preventing the fixing block 31 from automatically moving downward, thereby improving the fixing effect;

[0036] During disassembly, it is only necessary to move the fixed block 31 downward to separate the arc-shaped support portion 311 from the connecting block 43, and then move the connecting block 43 backward to separate the connecting protrusion 44 from the connecting slot 42. Then, the connecting block 43 can be pulled out of the connecting slot 41 to complete the disassembly.

[0037] In order to facilitate the movement of the lifting slider 32 , an anti-slip pattern 321 is provided on the lifting slider 32 .

[0038] In the present invention, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", "bottom", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are merely relational words determined for the convenience of describing the structural relationships of the various parts or elements of the present invention, and do not specifically refer to any part or element in the present invention, and cannot be understood as a limitation on the present invention.
