Abstract

The utility model relates to a torsion spring assisting type door hinge, which is of a double-shaft structure. Double shafts of the door hinge are a hinge spindle and an auxiliary shaft, a square box body is arranged outside one end of the hinge, the front end edge of the box body is provided with a fixing hole and fixedly connected with a door frame, a hinge spindle is vertically mounted on the inner side of the box body, and the auxiliary shaft is parallel to the spindle and arranged outside the box body. A connecting plate with a bent corner approximate to 90 degrees is mounted between the spindle and the auxiliary shaft, one end of the connecting plate is rolled on the spindle and in rotary connection with the spindle, and two end head extending portions at the other end of the connecting plate are bent at 90 degrees and sleeved on two end heads of the auxiliary shaft. A fixing plate is rolled on the auxiliary shaft and in rotary connection with the auxiliary shaft, an opening is reserved in the middle of the auxiliary shaft, a torsion spring is mounted at the position of the opening, and the torsion spring assisting type door hinge is mounted on an anti-theft door so that large-angle rotation can be performed. The whole hinge forms a whole after connected. The torsion spring assisting type door hinge has the advantages that the hinge adopts the double-shaft structure and is installed on the anti-theft door, the anti-theft door can be opened and closed at 180 degrees, people conveniently come in and go out of the anti-theft door, and large articles are conveniently carried in and out of the anti-theft door.

Description

Torque spring booster type door hinge

Technical field

The utility model relates to a kind of torque spring booster type door hinge, is adapted at installing and using on various anti-the forcing open the door.

Background technology

At present, the anti-employed hinge of forcing open the door mostly adopts the common model door hinge of selling on the market, and its structure is a single shaft pair of pages formula, and the centre is a rotating shaft; Two pages of sheets are engaged on the axle alternately, the page or leaf sheet is separately fixed on doorframe and the door leaf just can uses, and advantage is: simple in structure; Easy to install, its weak point is that the angle opened of door leaf is limited, is the restriction because of hinge arrangement; Cause the ready position of door to capture the confined space, on the other hand, when carrying large piece article in indoor discrepancy; Because of spacing is difficult to realize inadequately, very cause to compel sometimes not to be able to pluck door operation, make troubles to life.

Summary of the invention

For solving the deficiency of above pick-proof door hinge structure; The purpose of the utility model provides a kind of torque spring booster type door hinge; Adopt cross-compound arrangement; Increasing the anglec of rotation, thereby but reach the anti-wide-angle switch of forcing open the door, the carrying indoor easy access of large piece article and effectively utilize the purpose of channel space.

The structure design of the utility model is achieved in that this hinge includes rotating shaft, junction plate and spring, it is characterized in that rotating shaft is a cross-compound arrangement, and its twin shaft is hinge main shaft, countershaft, and hinge one end is the square box body of outside opening; The box body front end has fixing hole in the outer up and down, is fixedly connected with doorframe, in the box body inboard hinge main shaft is housed vertically; Bearing is equipped with in this main shaft lower end, parallel with main shaft and than main shaft short slightly be countershaft, between major and minor axle, be equipped with and be similar to 90 and spend the bent angle junction plates; Junction plate one end twists on the main shaft and with main shaft and is rotationally connected, and other end two ends extension distortion 90 degree are enclosed within the countershaft two ends, simultaneously; Volume has fixed head on countershaft, and this fixed head and countershaft are rotationally connected, and plane, fixed head outer and curled portion are divided into 90 degree bent angles; The outer has fixing hole on the plane, and being fixedly connected with the door body, fixed head is with after countershaft is connected; Bearing is equipped with at the countershaft two ends, in the middle of countershaft, one section opening is arranged, and at opening part torque spring is housed; One end is fixed on the junction plate, and the other end is fixed on fixed head, and it is in aggregates that whole hinge connects the back.

The advantage of the utility model: this hinge adopts cross-compound arrangement, is positioned on anti-the forcing open the door, and anti-forcing open the door can be carried out 180 degree switches, and nothing wheel people still carry large piece article in indoor discrepancy and come in and go out very convenient.

The specific embodiment

The utility model structure and operating principle combine embodiment to explain.

Its structure such as Fig. 1, shown in 2, hinge box body 1 outer has fixing hole, and crouching fixes in door frames; Interior dress main shaft 2, countershaft 4 is equipped with in box body 1 outside, and middle with junction plate 3 connections, junction plate 3 approximate 90 is spent bent angles; Twist in respectively on the diaxon 2,4 and with diaxon and be rotationally connected, main shaft 1 is equipped with axle and becomes 7, and countershaft 4 is equipped with bearing 8 up and down; For easy to process, junction plate 3 is two sections, and middle with 9 fixed connections of sheath screw, fixed head 5 is equipped with in countershaft 4 outsides; Fixed head 5 outsides are a flat board, have fixing hole in the plane, are fixedly connected with the door body, leave one section opening in the middle of countershaft 4 upper mounted plates 5 crimping portion; At opening part torque spring 6 is housed, spring one end is fixed on the junction plate, and the other end is fixed on the fixed head, and this hinge generally adopts steel material to process.

Use: hinge box body and doorframe fix, and fixed head fixes with anti-forcing open the door, and the rotary door body is because the pressure of spring; Main shaft begins earlier to rotate, because of the diaxon junction plate is 90 degree, more than rotatable 90 degree of door body, because the restriction of box body; Be rotated further a body again, fixed head begins to rotate, and length of spring compressed can also be rotated 90 degree with the fixing fixed head of door body; Therefore this hinge can make the pick-proof door carry out the wide-angle rotation, otherwise, when at closing time, because the pressure of spring; Fixed head forwards original position naturally earlier to, rotary door body then, and main shaft rotates, and back door body sets back.

Should be understood that the utility model is not only limited to the structure of the foregoing description, in the scope of the purport that does not change the utility model, concerning those skilled in the art of common knowledge with this area, also can carry out various changes and distortion.Therefore, such change and distortion should be interpreted as scope of the present invention and be included in the scope of the utility model.
