DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Reference Figure 1-Figure 4 , an anti-theft door with adjustable opening, comprising a door frame 1 and an anti-theft door body 2, the anti-theft door body 2 is rotatably connected to the door frame 1 through a hinge, the outer wall of the anti-theft door body 2 is rotatably connected to a first connecting rod 3, the inner wall of the door frame 1 is rotatably connected to a second connecting rod 4, and the first connecting rod 3 and the second connecting rod 4 are connected by a locking mechanism 5;

[0024] The locking mechanism 5 includes a limiting plate 9 fixed to the first connecting rod 3 , and a fixing plate 8 is fixedly connected to the second connecting rod 4 , and a clamp is arranged inside the fixing plate 8 .

[0025] In this embodiment, a plurality of limiting grooves 10 are evenly formed on the outer wall of the limiting plate 9 , the clamping member includes an insertion rod 12 , and a plug hole 11 for the insertion rod 12 to pass through is formed on the fixed plate 8 , and the insertion rod 12 is adapted to the limiting grooves 10 .

[0026] In this embodiment, a connecting block 14 is fixed to the bottom of the insertion rod 12, a spring 13 is fixed to the top of the connecting block 14, the spring 13 is sleeved on the outer wall of the insertion rod 12, and the top of the spring 13 is fixed to the bottom of the fixed plate 8.

[0027] In this embodiment, a connecting rod is fixed to the bottom of the connecting block 14 , a hole is formed on the connecting rod, and a pull ring 15 is disposed in the hole.

[0028] In this embodiment, one end of the first connecting rod 3 away from the locking mechanism 5 is rotatably connected to the middle position of the outer wall of the anti-theft door body 2 .

[0029] In this embodiment, a right-angle workpiece 6 is fixed to one end of the second connecting rod 4 away from the locking mechanism 5, a connecting head 7 is fixed to the middle of the top of the inner wall of the door frame 1, the bottom of the connecting head 7 is rotatably connected to the top of the right-angle workpiece 6, the right-angle workpiece 6 is fixed to the second connecting rod 4, and the connecting head 7 is rotatably connected to the right-angle workpiece 6. When the anti-theft door body 2 is closed, the first connecting rod 3 can be located above the second connecting rod 4 to form a parallel position without interfering with each other.

[0030] Working principle: When in use, through the door frame 1, the anti-theft door body 2, the first connecting rod 3, the second connecting rod 4 and the locking mechanism 5, the locking mechanism 5 includes a fixed plate 8, a limit plate 9, a limit groove 10, a socket 11, a plug rod 12, a spring 13, a connecting block 14 and a pull ring 15, and a pull rope is tied to the pull ring 15. When the angle of the anti-theft door body 2 needs to be adjusted, the pull rope is pulled to make the plug rod 12 move down in the socket 11 on the fixed plate 8, so that the spring 13 contracts and the plug rod 12 is separated from the limit groove 10 on the limit plate 9. The limit on the limit plate 9 is released, so that the limit plate 9 and the fixed plate 8 can rotate relative to each other, so that the first connecting rod 3 and the second connecting rod 4 can adjust the angle. After the adjustment is completed, the pull rope is released, and the spring 13 returns to its original state, so that the insertion rod 12 limits the limit plate 9, so that the angle of the first connecting rod 3 and the second connecting rod 4 is locked, and the angle of the anti-theft door body 2 is fixed. Through the above technical means, the angle adjustment of the anti-theft door body 2 and the limit control can be achieved, which is practical and convenient, and can prevent it from being moved by wind or slight collision;

[0031] Further, such as Figure 2 As shown, when the first connecting rod 3 and the second connecting rod 4 are at right angles, the insertion rod 12 is located on the left side of the fixed plate 8. When the anti-theft door body 2 is closed toward the door frame 1, the fixed plate 8 rotates so that the insertion rod 12 rotates counterclockwise without squeezing and interfering with the second connecting rod 4, and can be completed and unfolded;

[0032] Furthermore, a right-angle workpiece 6 is fixed on the second connecting rod 4, and a connecting head 7 is rotatably connected to the right-angle workpiece 6. When the anti-theft door body 2 is closed, the first connecting rod 3 can be located above the second connecting rod 4 to form a parallel relationship without interfering with each other.
