Abstract

The utility model relates to a structure-improved hinge without a door frame, a set of fixing clamping piece covers and one end of the bottom of the clamping pieces are connected with a pin joint seat, wherein, the pin joint seat is provided with a shaft hole and a plurality of trepan borings which are vertically intersected with the shaft hole; the interior of each trepanning is provided with a cylinder, a spring, and a spring seat; a rotating shaft is arranged in a hole of a pin joint bottom shaft; both ends of the rotating shaft are connected with the other set of clamping piece covers and the bottom of clamping pieces. The utility model is characterized in that the middle position of the rotating shaft is provided with a locating slot, and the cylinder can be positioned under the action of the spring; the locating slot which is arranged in the rotating slot is arranged at the position of a direction angle alpha on the circumference can be changeable adjusted according to different requirements.

Description

Structure improved no doorframe hinge

The utility model relates to no doorframe hinge, refer to especially a kind of can select to locate close the door or the no doorframe hinge of open angle.

Generally be installed in the door of access, except automatic door, what general door-plate can be divided into single material lamellar body frameless door and the box-like door of structural group sheet substantially has a frame door.And have the frame door to have preferable protective, therefore, usually use in the place that needs protective, as gate etc., and frameless door is generally the full wafer glass door panel, generally is used for office or doorway, shop as non-protective, only as the purposes of obstruct.And must close the door automatically after opening the door because of needs in some place, and along with the applying of glass door, the closing angle of door also respectively is not quite similar.

The purpose of this utility model is to provide a kind of structure improved no doorframe hinge that can select positioned at arbitrary angles to close the door or open the door according to customer requirements.

For reaching above-mentioned purpose, the utility model connects a pin joint seat by one group of fixing intermediate plate lid and the end at the bottom of the intermediate plate, pin joint seat has an axis hole and several vertical trepannings that passes through of handing over axis hole, be built-in with a cylinder at each trepanning, one spring and a spring base, in the pin joint seat axis hole, be equipped with a rotating shaft, the two ends of rotating shaft connect at the bottom of another group intermediate plate lid and the intermediate plate, be characterized in: be provided with a locating slot in the rotating shaft middle part, be used for cylinder and under spring action, implement the location, locating slot in the rotating shaft, the position of the direction angle alpha on circumference can change setting according to different needs.

The utility model has the advantages that, rotating shaft has a locating slot, cylinder is implemented the location under spring action, when opening the door, rotating shaft is rotated with door, cylinder is made radial rolling on rotating shaft surface, spring action lower edge, and the angle of closing the door or open the door in the location can make corresponding changes the direction position of rotating shaft locating slot on circumference according to the different needs of user.

Each label is represented in the above-mentioned accompanying drawing:

At the bottom of the 1-intermediate plate, 2, the 19-screw, 3-cylinder screw, 4-axis hole, the 5-trepanning, 6-pin joint seat, 7-cylinder, 8-spring base, the 9-spring, 10,13-intermediate plate lid, 11, the 14-hole, 12,15-screw, 16-screw, 17-spring washer, at the bottom of the 18-intermediate plate, 20, the 21-hole, the 22-packing ring, the 23-rotating shaft, 24-locating slot, 25, the 26-screw.

At first see also shown in Figure 1, the utility model by one group of fixing intermediate plate lid 13 and intermediate plate at the bottom of 18 usefulness screws 16 connect with pin joint seat 6, the door of clamping simultaneously sheet connects with screw 15, pin joint seat 6 has an axis hole 4 and several and the axis hole 4 vertical trepannings 5 that pass through of handing over, be built-in with a cylinder 7 (or steel ball), a spring 9 and a spring base 8 at each trepanning 5, be equipped with a rotating shaft 23 in the axis hole 4,1 clamping door sheet at the bottom of rotating shaft 23 two ends connect another group intermediate plate lid 10 and intermediate plate tightens up with screw 12.See by figure, among the rotating shaft 23 in the utility model between the position be provided with a locating slot 24, cylinder 7 (or steel ball) presses down in spring 9 effect and is forced into bottom land, implement the location, the position of the direction angle alpha of this locating slot 24 on circumference can change setting according to different needs, sees Fig. 2, shown in Figure 5.

The utility model is when opening the door, and rotating shaft 23 is rotated with door, and cylinder 7 is made radial rolling on spring 9 effect lower edge rotating shafts 23 surfaces, revolution at closing time, when the angle of door was spent less than 30, door-plate still to oppress cylinders 7 to rotating shaft 23 locating slots bottom by spring 9 effects, this moment, finished by locating closing.
