The beneficial effects of the utility model：This height adjustable door hinge, doorframe connecting plate and door leaf connecting plate are individually fixed in
On doorframe and door leaf, two thrust bearings can reduce frictional resistance during door leaf connecting plate rotation, reduce abrasion, be adjusted by two
The upper-lower height of shaft is adjusted in screw, and shaft is fixedly connected with door leaf connecting plate by bolt, so as to adjust door leaf connecting plate
With the height of door leaf so that door leaf is not contacted with ground, and total design is simple.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the front view of the utility model embodiment；
Fig. 2 is the vertical view of the utility model embodiment.
Specific embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of height adjustable door hinge, including doorframe connecting plate 1, door leaf connecting plate 2
With shaft 3, the centre of 2 inside of upper and lower ends and door leaf connecting plate of 1 inside of doorframe connecting plate is equipped with reel 4, and shaft 3 passes through
Reel 4 on door leaf connecting plate 2 further includes the reel 4 being inserted perpendicularly on door leaf connecting plate 2 and the bolt 6 of shaft 3, shaft 3
The two winding drum 4 on doorframe connecting plate 1 is inserted at both ends, and the both ends of shaft 3 are equipped with thrust bearing 5, volume two on doorframe connecting plate 1
Internal thread is equipped in cylinder 4, further includes two adjusting screws 7 with screw-internal thread fit.
This height adjustable door hinge, doorframe connecting plate 1 and door leaf connecting plate 2 are individually fixed on doorframe and door leaf.3 liang of shaft
The thrust bearing 5 at end can reduce frictional resistance when door leaf connecting plate 2 rotates so that the rotation of door leaf is more smooth, reduces
Abrasion.Two thrust bearings 5 and two adjusting screws, 7 countershaft 3 play the role of fixed and position simultaneously.After a period of use,
Door leaf is sagging to be contacted with ground, and the height of door leaf can be adjusted by adjusting screw 7.First unscrew the adjusting screw 7 of top, make shaft
3, in adjustable state, tighten the adjusting screw 7 of lower section, adjusting screw 7 pushes thrust bearing 5, thrust bearing 5 then up
Shaft 3 is pushed to move up, since shaft 3 is fixedly connected with door leaf connecting plate 2 by bolt 6, the drive door leaf connecting plate of shaft 3
2 move up, so as to which door leaf be driven to move up.Similarly, when needing to move down door leaf, first unscrew the adjusting screw 7 of lower section, then tighten
The adjusting screw 7 of side.
As the utility model preferred embodiment, door leaf connecting plate 2 is equipped with Anti-theft buckle 21, doorframe connecting plate 1
Upper and 21 symmetrical position of Anti-theft buckle is equipped with antitheft card hole 11.
Since adjusting screw 7 and bolt 6 are easier to dismantle, when door leaf is closed, the personnel of committing theft dismantle 7 He of adjusting screw
Bolt 6, you can shaft 3 is pulled out, although door leaf closing can extract door leaf out along the direction for being parallel to door leaf, so as to door leaf of dismantling
Into within doors.And Anti-theft buckle 21 and antitheft card hole 11 can prevent door leaf to be extracted, when door leaf is closed, Anti-theft buckle 21 is inserted into
Antitheft card hole 11, so as to which the personnel of committing theft can not extract door leaf out.Anti-theft buckle 21 and antitheft card hole 11 play antitheft effect.
