Detailed Description
The adjustable fence door hinge according to the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1-4, an adjustable fence door hinge comprises a main frame 1 and a sub-frame 2; it is characterized by also comprising a connecting piece 3 which is arranged on the main frame 1 and the auxiliary frame 2 and can adjust the distance between the main frame 1 and the auxiliary frame 2; the connecting piece 3 comprises a fixed frame 31 arranged on the main frame 1, a fixed rod 32 arranged on the fixed frame 31, a rotating sleeve 33 movably arranged on the fixed rod 32 and an adjusting mechanism 4 arranged on the auxiliary frame 2 and the rotating sleeve 33; through the setting of adjustment mechanism 4, can adjust the interval between body frame 1 and the subframe 2 according to the interval between door plant and the door frame to improve the application scope of product.
Further, the adjusting mechanism 4 comprises an adjusting screw 41 installed on the rotating sleeve 33, a connecting sleeve 42 installed on the sub-frame 2 and movably connected with the adjusting screw 41, and adjusting nuts 43 installed on the adjusting screw 41 through threads and located at two sides of the connecting sleeve 42; by installing the adjusting nuts 43 on both sides of the connecting sleeve 42, the position of the connecting sleeve 42 on the adjusting screw 41 can be changed by changing the positions of the two adjusting nuts 43 on the adjusting screw 41, thereby changing the distance between the main frame 1 and the sub-frame 2.
Furthermore, fixed sleeves 34 are riveted at two ends of the fixed rod 32, the fixed sleeves 34 are positioned at two sides of the fixed frame 31, the fixed sleeve 34 at one side is provided with a clamping hole 35, and a torsion spring 36 is arranged between the rotating sleeve 33 and the fixed rod 32; through installing torsional spring 36 between rotating sleeve 33 and dead lever 32, drive body frame 1 or subframe 2 and rotate after the door is opened, drive body frame 1 or subframe 2 through torsional spring 36's restoring force after rotating and reset, body frame 1 or subframe 2 then drive the door and reset, carry out automatic closing door.
Further, a clamping groove 37 is formed in one side of the rotating sleeve 33, one end of the torsion spring 36 is clamped in the clamping groove 37, and the other end of the torsion spring is clamped in the clamping hole 35; through the setting of draw-in groove 37 and card hole 35, fix the both ends position of torsional spring 36 to when rotatory rotating sleeve 33, rotating sleeve 33 drives torsional spring 36 rotation through draw-in groove 37, and the torsional spring 36 drives rotating sleeve 33 through self restoring force after loosening and resets.
