Description

Technical Field

[0001] The invention relates to a hinge. Background Art

[0002] As people's living standards improve, their pursuit of quality of life is also getting higher and higher. For example, traditional entrance doors do not have a side guard extending from the door leaf to one side of the door frame, and wind can easily enter from the gap between the door leaf and the door frame. Many existing entrance doors have a side guard extending from the door leaf to one side of the door frame to prevent wind from directly entering the house from the gap between the door leaf and the door frame. However, the existing hidden hinges for doors can only adjust the up and down position of the door leaf in the door frame and the left and right position of the door leaf in the door frame, but cannot adjust the front and back position between the door leaf and the door frame, so that the distance between the side guard of the door leaf and the door frame is difficult to assemble appropriately. If the distance between the side guard of the door leaf and the door frame is large, the windproof effect is relatively poor. If the distance between the side guard and the door frame is too small, the side guard is easy to press against the door frame and damage the door frame and the side guard when closing the door. Summary of the invention

[0003] In view of the defects of the existing concealed hinges, the technical problem to be solved by the present invention is to provide a precision six-dimensional adjustable concealed hinge which can be adjusted in six directions: up, down, left, right, front and back.

[0004] In order to achieve the above object, according to one aspect of the present invention, the present invention is implemented by the following technical measures: a precision six-dimensional adjustable concealed hinge, comprising:

[0005] A lower seat body, wherein the lower seat body is provided with an adjustment block capable of sliding forward and backward, and the adjustment block is provided with an eccentric shaft hole II, and the lower seat body is provided with an eccentric shaft hole I opposite to the eccentric shaft hole II;

[0006] The upper seat body includes a crossbeam, and upwardly extending fixed seats are arranged on both sides of the crossbeam, a hinge shaft is connected between the two fixed seats, and an adjusting bolt is arranged on each of the two fixed seats, the crossbeam is clamped on the outside of the adjusting block, and an eccentric shaft hole III is arranged opposite to the eccentric shaft hole II;

[0007] A pressing block, which consists of two pieces and is disposed on both sides of the two fixing seats. The pressing block is fixed to the lower seat body, and positioning bolts for fixing the two ends of the crossbeam are provided on the pressing block;

[0008] An eccentric shaft I, wherein the eccentric shaft I connects the eccentric shaft hole I, the eccentric shaft hole II and the eccentric shaft hole III, and the eccentric shaft hole II can move left and right along the eccentric shaft I;

[0009] The flip connection seat is a U-shaped seat, one vertical side of which is used for the hinge shaft to be inserted, and can be flipped back and forth around the hinge shaft;

[0010] The door leaf fixing seat is clamped on the vertical edge of the other side of the flip connection seat, and the door leaf fixing seat can move up and down, and an eccentric shaft II is fixed between the door leaf fixing seat and the flip connection seat.

[0011] This precision six-dimensional adjustable concealed hinge is designed to loosen the positioning bolts of the upper seat body by loosening the two pressure blocks, and rotate the adjusting bolts to press the corresponding pressure blocks to move the upper seat body to the left or right along the adjusting blocks, so that the upper and lower seat bodies can be displaced left and right, loosen the flip connecting seat and the door leaf fixing seat, and rotate the eccentric shaft II to allow the door leaf fixing seat and the flip connecting seat to be displaced. If you need to adjust the gap between the door leaf retaining edge and the door frame, first loosen the positioning bolts, and then rotate the eccentric shaft I to allow the eccentric shaft I to push the adjusting block to slide back and forth along the adjusting seat of the lower seat body.

[0012] Furthermore, two opposite columns are fixed at each end of the lower seat, and the columns are provided with plug-in holes. The lower end of the pressing block is provided with a plug-in column plugged into the plug-in hole and fixed by bolts, and the two ends of the crossbeam are clamped between the two columns and can move. The above design facilitates the installation of the upper seat, and the structure is more reasonable.

[0013] Furthermore, the center of the lower seat body is provided with an adjustment seat, the lower seat body on both sides of the adjustment seat is provided with grooves, the adjustment seat is provided with two opposite strip-shaped slide grooves, and the eccentric shaft hole I is located between the two strip-shaped slide grooves, and the adjustment block is provided with a clamping arm clamped in the strip-shaped slide groove. The above design is more stable when moving.

[0014] Furthermore, a clamping seat is extended toward the hinge shaft on the side of the cross beam opposite to the hinge shaft, the cross beam is clamped on the outside of the adjustment block through the clamping seat, and the eccentric shaft hole III is arranged on the clamping seat. The above design structure is more reasonable.

[0015] Furthermore, a shaft sleeve is fixed on one vertical side of the flip connection seat, and the shaft sleeve is plugged into the hinge shaft. A connecting plate is extended upward on the other vertical side of the flip connection seat, and an eccentric shaft hole IV is provided on the connecting plate. The door leaf fixing seat includes a fixing part and a plug-in part. The plug-in part is a semi-enclosed body with openings on the front side and the lower end, which is used to be clamped on the outside of the connecting plate, and an eccentric shaft groove is provided in the middle part. An eccentric shaft hole V is provided at the bottom of the eccentric shaft groove. Vertical strip bolt holes are provided on the plug-in parts on both sides of the eccentric shaft groove. The eccentric shaft II connects the eccentric shaft hole V and the eccentric shaft hole IV. The bolt holes on the connecting plate are connected and fixed with the strip bolt holes of the plug-in part of the door leaf fixing seat through bolts. The above design structure is very reasonable, and at the same time, the plug-in part of the door leaf fixing seat is very convenient to fix and move, and the structure is more reliable.

[0016] Furthermore, the eccentric shaft II has the same structure as the eccentric shaft I, both of which are composed of an eccentric shaft block in the middle and shaft rods arranged at both ends of the eccentric shaft block. The eccentric shaft block of the eccentric shaft II is inserted into the eccentric shaft groove, and the eccentric shaft block of the eccentric shaft I is inserted into the eccentric shaft hole II.

[0017] Compared with the prior art, the advantages of the present invention are: the precision six-dimensional adjustable concealed hinge of the present invention can enable the door leaf to be adjusted in six directions of up, down, left, right, front and back in the door frame, so that the door leaf and the door frame can fit more closely, and effectively prevent wind from entering the house through the gap between the door frame and the door leaf.
