[0027] In this embodiment, the door frame guide rail 1 is installed in the connecting bracket 2, and the connecting plate 24 is determined according to the installation height of the door frame guide rail 1. After the connecting plate 24 is slid to the corresponding position in the slide groove 23, the connecting plate 24 is fixed. When the lateral distance cannot meet the requirements, the turning handle 27 is rotated, and the turning handle 27 drives the threaded sleeve 26 to rotate together. The threaded sleeve 26 rotates on the surface of the threaded rod 25 to control the extension length of the threaded rod 25. After the threaded sleeve 26 is rotated to a suitable position, the connecting head 28 is fixed to the interior of the car to complete the installation of the connecting bracket 2. It can meet the installation of various models of door frame guide rails 1 and can also meet the requirements of different distances, thereby improving the applicability of the device.

[0028] Example 2

[0029] like Figure 1-5It is shown that on the basis of Example 1, the utility model provides a technical solution: preferably, the connecting head 28 includes a turning platform 281 movably connected to one end of the threaded sleeve 26, the interior of the turning platform 281 is movably connected with a longitudinal rotating platform 282, the other end of the longitudinal rotating platform 282 is movably connected with a fixing frame 283, and the side of the fixing frame 283 is provided with a fixing hole 284, the side of the turning platform 281 is movably connected with a tightening knob 285, the side of the tightening knob 285 is fixedly connected with a tightening stud 286, the tightening stud 286 is movably connected to the longitudinal rotating platform 282, the surface of the longitudinal rotating platform 282 is fixedly connected with a chassis serration 287, the surface of the longitudinal rotating platform 282 is fixedly connected with a groove 289, the surface of the longitudinal rotating platform 282 and the inside of the groove 289 is fixedly connected with a groove serration 288, and the groove serration 288 is adapted to the chassis serration 287.

[0030] In this embodiment, when installing the connecting bracket 2, bolts are used to pass through the fixing holes 284 to fix the fixing frame 283. The longitudinal rotating table 282 inside the turning table 281 can be rotated longitudinally, and the fixing frame 283 can be rotated laterally inside the longitudinal rotating table 282 to meet the installation requirements of various degrees of freedom. After rotating each part to a suitable angle, the tightening knob 285 is turned. The rotation of the tightening knob 285 will drive the tightening stud 286. The rotation of the tightening stud 286 will cause the chassis serrations 287 on the surface of the fixing frame 283 to contact the chassis serrations 287 inside the groove 289, thereby fixing the various rotating tables to prevent them from rotating, thereby avoiding loosening during operation and improving the reliability of the device.

[0031] Example 3

[0032] like Figure 1-5 It is shown that, on the basis of Example 1, the utility model provides a technical solution: preferably, the mounting buckle 22 includes a mounting frame 221 fixedly connected to the surface of the bracket mainboard 21, the mounting frame 221 is internally slidably connected with a positioning rod 222, the surface of the positioning rod 222 is fixedly connected with a baffle 225, the surface of the mounting buckle 22 is sleeved with a positioning spring 223, the two ends of the positioning spring 223 are respectively fixedly connected to the baffle 225 and the mounting frame 221, and the other end of the positioning rod 222 is fixedly connected with a pull block 224.

[0033] In this embodiment, the pull block 224 is pulled upward, and the upward movement of the pull block 224 will drive the baffle 225 to move upward together. During the upward movement of the baffle 225, the positioning spring 223 is compressed, and the positioning rod 222 is pulled out at the same time. After the door frame guide rail 1 is installed inside the connecting bracket 2, the pull block 224 is released, and the positioning spring 223 is reset to push the baffle 225 to move downward. The downward movement of the baffle 225 drives the positioning rod 222 to be inserted into the door frame guide rail 1, thereby fixing the door frame guide rail 1 inside the connecting bracket 2, thereby improving the convenience of the device.

[0034] The working principle of the connecting bracket of the door frame guide rail is described in detail below.

[0035] like Figure 1-5 As shown, the door frame guide rail 1 is installed in the connecting bracket 2, and the connecting plate 24 is determined according to the installation height of the door frame guide rail 1. After the connecting plate 24 is slid to the corresponding position in the slide groove 23, the connecting plate 24 is fixed. When the lateral distance cannot meet the demand, the turning handle 27 is turned, and the turning handle 27 drives the threaded sleeve 26 to rotate together. The threaded sleeve 26 rotates on the surface of the threaded rod 25 to control the extension length of the threaded rod 25. After the threaded sleeve 26 is rotated to a suitable position, the connecting head 28 is fixed to the interior of the car to complete the installation of the connecting bracket 2.

The locking stud 286 rotates to make the chassis serrations 287 on the surface of the fixing frame 283 contact with the chassis serrations 287 inside the groove 289, thereby fixing and preventing each rotating table from rotating, thereby avoiding loosening during operation. The pull block 224 is pulled upward. The upward movement of the pull block 224 will drive the baffle plate 225 to move upward together. During the upward movement of the baffle plate 225, the positioning spring 223 is compressed and the positioning rod 222 is pulled out at the same time. After the door frame guide rail 1 is installed inside the connecting bracket 2, the pull block 224 is released. The reset of the positioning spring 223 will push the baffle plate 225 downward. The downward movement of the baffle plate 225 drives the positioning rod 222 to be inserted into the door frame guide rail 1, thereby fixing the door frame guide rail 1 inside the connecting bracket 2.
