Three-dimensional adjustable swivel arm hinge

Abstract

The patent of the present invention discloses a three-dimensional adjustable swivel arm hinge, which consists of two parts: a three-dimensional hinge adjustment seat for a door leaf and a swivel arm hinge assembly. The three-dimensional hinge adjustment seat for a door leaf consists of a swivel arm fixing seat, a fixing seat mounting plate, an eccentric shaft, a fixing seat screw, a pressure plate, a swivel arm fixing screw and an up and down adjustment screw. The swivel arm hinge assembly consists of a swivel arm, a shaft sleeve, a swivel shaft, a door frame swivel shaft bracket, a bracket decorative cover, a swivel arm box and a screw C. The swivel arm hinge assembly can be moved left and right along the notch direction of the T-slot support leg to adjust the left and right gap between the door leaf and the door frame. The swivel arm hinge assembly can be adjusted to move up and down by adjusting the up and down adjustment screws of the T-slot support leg to achieve the up and down position adjustment of the door leaf and the door frame. The swivel arm hinge assembly can be adjusted to move forward and backward relative to the fixing seat mounting plate by rotating the eccentric shaft to achieve the gap between the overlapping sealing strip surfaces of the door leaf and the door frame.

Description

(I) Technical field

[0001] The patent of this invention relates to a three-dimensional adjustable rotating arm hinge of a hinge (or hinge), which belongs to the hardware product category. (II) Background technology

[0002] Hinges are the main components of door products. Usually, they are fixed to the door leaf and door frame, or even installed during installation. Especially in the industrialized door products nowadays, assembly and installation are extremely inconvenient, especially for steel door products. Due to the sheet metal manufacturing precision, a three-dimensional adjustable door hinge is very necessary to adjust the assembly precision and clearance requirements between the door leaf and the door frame, so as to facilitate product assembly, installation and commissioning. (III) Summary of the invention

[0003] The technical problem to be solved by the patent of this invention is to provide a three-dimensional adjustable swivel arm hinge, which has a three-dimensional adjustment function, allowing the user to easily adjust the position and gap between the door leaf and the door frame.

[0004] The following is the technical solution adopted by the patent of this invention:

[0005] The three-dimensional adjustable swivel arm hinge is composed of two parts: a three-dimensional hinge adjustment seat for a door leaf and a swivel arm hinge assembly. The three-dimensional hinge adjustment seat for a door leaf is composed of a swivel arm fixing seat, a fixing seat mounting plate, an eccentric shaft, a fixing seat screw, a pressure plate, a swivel arm fixing screw, and upper and lower adjustment screws. The swivel arm fixing seat is provided with a mounting base plate, a T-slot support foot, a screw hole A, a screw hole B, a circular hole, and a long waist circular hole. The fixing seat mounting plate is provided with a screw hole that matches the fixing seat screw. The swivel arm fixing seat is connected and fixed to the fixing seat mounting plate with the fixing seat screw. Long waist circular forming holes and rectangular forming holes are designed on the fixing seat mounting plate. The large end of the eccentric shaft is installed in the long waist circular forming hole and matched therewith, and the small end of the eccentric shaft is installed in a movable fit with the circular hole of the swivel arm fixing seat. The swivel arm fixing seat is provided with a mounting base plate and a T-slot support foot perpendicular to the mounting base plate. The T-slot foot is used to fix the swivel arm hinge assembly, and the swivel arm hinge assembly is installed and fixed on the swivel arm fixing seat through a pressure plate, a swivel arm fixing screw and an upper and lower adjustment screw.

[0006] The T-slot leg plug-in part of the swivel arm and the swivel arm fixing seat of the swivel arm hinge assembly is provided with swivel arm fixing screws, the total number of which is equal to the sum of one square hole and the number of square opening holes, and the swivel arm fixing screws are designed to fit with the square hole and the square opening hole in a large clearance. The swivel arm hinge assembly is composed of a swivel arm, a shaft sleeve, a shaft, a door frame shaft bracket, a bracket decorative cover, a swivel arm box, and a screw C. Sleeves are provided at both ends of the rolled circular hole of the swivel arm, and the shaft passes through the shaft sleeves at both ends of the swivel arm and slides with the inner hole of the shaft sleeve and is riveted or welded to the outside of the two supporting holes on the door frame shaft bracket. The swivel arm box is fixed to the screw holes on the two side plates of the door frame shaft bracket by screws C passing through the mounting holes on both sides of the swivel arm box. The swivel arm box can also be connected to the door frame shaft bracket by a buckle or by welding. The three-dimensionally adjustable swivel arm hinge of the swivel arm of the present invention has a through hole in the notch of the T-slot support foot on the swivel arm fixing seat, and the swivel arm hinge assembly can be moved left and right along the notch direction of the T-slot support foot to adjust the left and right gap between the door leaf and the door frame. The swivel arm hinge assembly can be adjusted to move up and down by adjusting the up and down adjustment screws of the T-slot support foot, thereby realizing the up and down position adjustment of the door leaf and the door frame, and the front and rear position adjustment of the swivel arm hinge assembly relative to the fixing seat mounting plate can be adjusted by rotating the eccentric shaft, thereby realizing the gap between the overlapping sealing strip surfaces of the door leaf and the door frame.

[0007] In addition, a set of screw holes and two convex truncated cone screw holes are provided on the two mounting feet connecting the door frame pivot bracket and the door frame, and the bracket decorative cover is installed on the convex truncated cone screw holes of the two mounting feet of the door frame pivot bracket with screws. A set of screw holes is used to connect the door frame pivot bracket with the door frame, or directly weld the door frame pivot bracket with the door frame, and the bracket decorative cover is used to decorate the door frame hinge hole to make it beautiful in appearance.
