Example 1

As shown in fig. 1 to 6, the novel connector for a door frame and a door leaf of an anti-theft door, which facilitates maintenance and replacement of the door leaf, according to the present embodiment includes two hinges 1, and the inner side walls of the two hinges 1 are connected through a connecting rod. The hinge 1 is a standard part, the two hinges 1 have the same structure, when in installation, one of the hinges is inverted, the two hinges can be buckled, a plurality of mounting holes are uniformly distributed on the hinge 1, and the number of the mounting holes is determined according to the bearing. The hinge 1 is provided with a blind hole 101 and a through hole 102 which are matched with the connecting rod, one end of the connecting rod penetrates through the through hole, and the other end of the connecting rod extends into the blind hole, so that the two hinges 1 can be connected.

The connecting rod comprises a sleeve 7, a supporting rod 2, a pushing block 3, a frame cylinder 6 and a threaded rod 5, wherein the frame cylinder 6 is sleeved in the sleeve 7 and is in sliding connection with the sleeve 7, the sleeve 7 provides better rigid support, and meanwhile the supporting force of the frame cylinder 6 is enhanced. 2 one end of branch and ejector pad 3 fixed connection, 3 at least parts of ejector pad and 7 inner wall sliding connection of sleeve, ejector pad 3 be equipped with 4 pivoted circle chambeies of circle piece, 5 one ends of threaded rod and 4 fixed connection of circle piece, the other end pass a frame section of thick bamboo 6 tip and rather than threaded connection, branch 2, ejector pad 3, a frame section of thick bamboo 6, threaded rod 5 are two, and symmetrical arrangement is at 7 both ends of sleeve, and two threaded rods 5 are reverse screw with the screw thread of a frame section of thick bamboo 6. The rigidity of the sleeve 7, the tight sliding connection between the push block 3 and the sleeve 7 and the connection between the frame barrel 6 can meet the rigid support of the rotating shaft and meet the installation requirement of the door leaf 10.

Threaded rod 5 and frame section of thick bamboo 6 spiro union, rotate threaded rod 5 promptly and can make the round piece 4 take the ejector pad to advance, and the one end that threaded rod 5 is located frame section of thick bamboo 6 here is equipped with nut 8, and the top surface of nut 8 is equipped with the interior angle screw, and the interior angle screw can be interior four corners, interior hexagonal, adjusts through interior angle spanner, interior angle screwdriver, conveniently controls the process of threaded rod 5 to control the degree of depth that straight-bar 2 stretched into blind hole 101. The window 701 has been seted up to the outer wall of sleeve 7, can see inside frame section of thick bamboo 6 and threaded rod 5 through window 701, makes things convenient for direct adjustment threaded rod 5.

Use the utility model discloses during 9 door leafs 10 of structural connection door frame, door leaf 10 and door frame 9 need the notch that corresponds, as shown in figure 6, install the back promptly for interior installation, avoid even the machine to expose, better play the effect of theftproof.

During the assembly, threaded rod 5 in the connecting rod moves back earlier in the sleeve, with two hinge 1 locks, in threaded rod 5 stretched into through-hole 102, another threaded rod 5 was aligned with blind hole 101 position, made its boss 4 remove through adjusting threaded rod 5, boss 4 promoted ejector pad 3 and marchd to make branch 2 stretch into blind hole 101 in, the height and position of adjustment realized being connected of door leaf 10 and door frame 9. When the height of the door leaf 10 needs to be adjusted, an internal angle wrench can be directly used for stretching into the frame barrel 6 through the window 701 to adjust the threaded rod 5, as shown in fig. 5, fine adjustment can be achieved on the upper portion and the lower portion of the door leaf 10. It should be noted that the size ratio of the attached components may not be accurate, but does not affect the working principle and the description, through the utility model discloses the structure, can realize the quick replacement of connector, even if non-uniform door leaf 10 door frame 9 simultaneously, set up the notch on door leaf 10 door frame 9 and can realize the installation. The better method is that the door leaf 10 door frame 9 leaves a vertical through notch when being produced in a factory, which does not affect the product quality and the appearance and can meet various installation requirements. In use, the threaded rod 5 can be adjusted through the window at any time, the height of the door leaf 10 is adjusted, a connecting hinge or a connector does not need to be reset, and the door leaf height adjusting device is simple and convenient and saves cost.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
