Referring to fig. 1 to 4, an embodiment of the present application provides a fence door hinge, including a hinge body disposed between a fence post 100 and a fence net plate 200, the hinge body including a first frame body 1, a second frame body 2, a combination plate 3, and two locking members 4; two ends of the first frame 1 are respectively connected to two ends of the second frame 2 through a locking member 4, a through hole 121 for adapting to the fence upright post 100 is defined between the first frame 1 and the second frame 2, and a fixing hole 122 penetrates through the first frame 1 and/or the second frame 2; the combination plate 3 is located outside the first frame 1 and the second frame 2, the combination plate 3 is rotatably connected to one of the locking members 4, and the combination plate 3 is mounted on the rail net plate 200.

Referring to fig. 6 and 7, when the hinge body in the present application is used to connect the fence upright 100 and the fence plate 200, only the through hole 121 defined between the first frame 1 and the second frame 2 needs to be sleeved on the fence upright 100, and after the height is adjusted by sliding up and down, the first frame 1 and the second frame 2 are fixed on the fence upright 100 by installing a screw (or a bolt) through the fixing hole 122; in addition, the fence panel 200 can be fixed on the connecting plate 3 by welding or by installing the mounting holes 31 and screws (or bolts), so that the installation can be completed, and the fence panel 200 (i.e. the fence door) can rotate relative to the fence post 100.

Referring to fig. 6 and 7, the combination plate 3 is located outside the first frame 1 and the second frame 2, and after installation, the gap between the fence net plate 200 and the fence upright post 100 is increased, so that not only can collision between the fence net plate 200 and the fence upright post 100 be avoided, but also a foundation can be provided for installing a connecting piece with an annular structure, and the universality is stronger; in addition, on the premise of providing the mounting hole 31 and the abdicating hole 123, the gap between the combining plate 3 and the fence post 100 is increased after mounting, so as to accommodate the head of the screw (or bolt) in the mounting hole 31, so that the mounting hole 31 does not have to be a tapered structure.

Referring to fig. 4 and 5, in some embodiments of the present application, the first connection ring 11 is formed by winding both ends of the first frame body 1 outward of the through hole 121, and the second connection ring 21 is formed by winding both ends of the second frame body 2 outward of the through hole 121; the locking member 4 includes a mounting shaft 41 and two limiting portions 42, the mounting shaft 41 penetrates through the first connecting ring 11 and the second connecting ring 21, and the two limiting portions 42 are respectively connected to the upper and lower ends of the mounting shaft 41; one end of the coupling plate 3 is wound with a rotating ring 32, and the rotating ring 32 is rotatably connected to one of the mounting shafts 41. The structure is more convenient to process and install, can effectively reduce the processing cost, and can effectively improve the installation efficiency.

Referring to fig. 4 and 5, in some embodiments of the present application, two first connection rings 11 are symmetrically provided at both ends of the first frame body 1; a second connection ring 21 is provided at an end of the second frame body 2 away from the rotary ring 32, and the second connection ring 21 is located between the corresponding two first connection rings 11; two second connection rings 21 are symmetrically disposed up and down on one end of the second frame 2 close to the rotating ring 32, the two second connection rings 21 are located between the two corresponding first connection rings 11, and the two second connection rings 21 are symmetrically disposed on the upper and lower sides of the rotating ring 32. The layout mode is more symmetrical, the die opening cost of the die can be reduced, the processing is convenient, and the structural stability is higher; in addition, since the rotating ring 32 is positioned between the two corresponding second coupling rings 21 and the two second coupling rings 21 are positioned between the two corresponding first coupling rings 11, even if the two corresponding stopper portions 42 clamp the two corresponding first coupling rings 11 relatively tightly, the rotational resistance between the rotating ring 32 and the mounting shaft 41 is not increased by the supporting action of the two corresponding second coupling rings 21, and the flexibility of opening and closing the fence door can be maintained.

Referring to fig. 8, 9 and 10, in some embodiments of the present application, one of the limiting portions 42 is detachably connected to the mounting shaft 41. As shown in fig. 9, when the end of the first frame 1 and the second frame 2 deviating from the joint plate 3 is mounted by the locking member 4 with such a structure, the limiting portion 42 can be removed first, and the mounting shaft 41 can be taken out, so that the second frame 2 can rotate relative to the first frame 1, and is directly and horizontally inserted on the fence post 100, and the mounting is more convenient and the mounting efficiency is higher. As shown in fig. 10, similarly, when the locking member 4 having such a structure is mounted on the first frame body 1 and the second frame body 2 at the end close to the coupling plate 3; in addition, the disassembly of the combination plate 3 can be realized simultaneously, so that the combination plate 3 is firstly installed and fixed on the fence net plate 200, the installation shaft 41 is inserted into the first connecting ring 11 and the second connecting ring 21, the installation shaft 41 is lifted by one hand, the fence net plate 200 is lifted by the other hand so that the rotating ring 32 is aligned with the installation shaft 41, and then the fence net plate 200 can be loosened by lowering the installation shaft 41, and the installation mode is simpler and more labor-saving in operation; otherwise, if the first frame body 1, the second frame body 2 and the connecting plate 3 are installed first, the fence panel 200 needs to be lifted continuously and the fence panel 200 is kept still, so that the welding operation or the installation of screws (or bolts) through the installation holes 31 can be performed, which is relatively laborious.

Referring to fig. 8, 9 and 10, in some embodiments of the present application, the detachable connection between the limiting portion 42 and the mounting shaft 41 is a threaded connection. The detachable connection between the limit portions 42 and the mounting shaft 41 can be achieved by the screw connection, and the interval between the two limit portions 42 can be adjusted so that the first and second connection rings 11 and 21 and the rotation ring 32 can be sufficiently locked.

Referring to fig. 5, 6 and 7, in some embodiments of the present disclosure, the first frame body 1 and/or the second frame body 2 are provided with an avoiding hole 123 at a position corresponding to the combining plate 3. In the process of opening and closing the fence door, the receding hole 123 can prevent the screw (or bolt) in the connecting plate 3 and the mounting hole 31 from touching the first frame 1 and the second frame 2. In addition, a lock is often required to be arranged between one end of the fence panel 200 deviating from the combination plate 3 and the other fence upright post 100, and the lock may generate an error in the installation process, so that after the combination plate 3 rotates to be flush with the side surface of the first frame 1 (or the second frame 2), the lock is still not completely locked in place, and thus the fence door needs to be further rotated, and at this time, the abdicating hole 123 can allow the combination plate 3 (i.e., the fence door) to further rotate (i.e., the fence panel 200 in fig. 5 can further rotate counterclockwise by a certain angle); otherwise, the side surface of the first frame 1 (or the second frame 2) may restrict the coupling plate 3 (i.e., the fence door) from further rotation, thereby requiring the locking structure to be reinstalled.

Referring to fig. 5 and 6, in some embodiments of the present application, the first frame 1 has a structure of "Contraband" and the through hole 121 has a square structure. Since the existing fence post 100 is generally of a square structure, the through hole 121 of the square structure can just match with the fence post 100 of the square structure; in addition, when the first frame 1 is in a structure like the shape of Contraband, the structural layout is more symmetrical, which is beneficial to reducing the mold opening cost of the mold and is convenient for processing and installation.

Referring to fig. 5, in some embodiments of the present application, a bolt (or screw) may be inserted through the fixing hole 122 and screwed to the rail post 100. Of course, the fixing hole 122 may also be an internal threaded hole, which facilitates direct installation of a bolt, and realizes locking by static friction between the bolt and the bracket of the fence post 100, so that there is no need to punch a hole on the fence post 100 or install a self-tapping screw.

Referring to fig. 5, in some embodiments of the present application, a boss 124 is provided to protrude from the first frame body 1 and/or the second frame body 2 to an outer side of the through hole 121, and the fixing hole 122 is formed to extend along the boss 124 to an inner side of the through hole 121. The boss 124 can improve the overall strength on one hand; on the other hand, the boss 124 can extend the depth of the fixing hole 122, and the strength is higher; when the bolt is an internal thread hole, the depth of the thread can be improved, and the stability of the bolt after installation is higher.

To sum up, this rail hinge's structure is simpler, and overall arrangement is more reasonable, ingenious, is convenient for process, and it is more convenient to install, can effectively avoid producing the collision between rail door and the rail stand 100, and the commonality is stronger.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and such changes and modifications are intended to be within the scope of the application as claimed.
