Description

Inward-opening and inward-falling hinge

Technical Field

The utility model relates to an accessory on the window, concretely relates to internal opening and internal reversing hinge.

Background

The existing building is built more and more, the window is opened and closed greatly, the risk of falling objects from high altitude is easily caused, therefore, hinges with limiting functions are additionally arranged between a window frame and window sashes of a plurality of windows, the window sashes can only be opened at a certain angle, the cost of the hinges is higher, the window frame and the window sashes are hinged through the hinges which are opened inwards and inwards, the window sashes are enabled to rotate along the side sides of the window frame, the window sashes are installed on high floors, parts with limiting functions are required to be configured, the installation cost is increased, the limiting space of the window which is opened on the high floors is generally certain, and the requirement for airing some users can not be met sometimes.

Disclosure of Invention

In order to solve the problem, an object of the utility model is to provide a take limit function and can open the interior division of hinge of falling in of multiple angle to satisfy different users' demand.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an interior hinge of falling in interior division, includes the last hinge of being connected with the casement and the lower hinge of being connected with the window frame, goes up the hinge and cup joints in a pivot with lower hinge, the position that corresponds with last hinge on the pivot outer wall is equipped with curved spacing groove, and the bottom in this spacing groove still is equipped with one or more arcs and is the step form length and steadilys decrease the vice spacing groove of arranging in proper order, goes up the spiro union on the hinge and has the screw, and this screw tip can precession to spacing groove and one or more vice spacing inslot.

One side wall of the limiting groove and one side wall of the auxiliary limiting groove are on the same straight surface.

The hinge comprises a rotating shaft, a first limiting disc and a second limiting disc are arranged on the rotating shaft, the first limiting disc and the second limiting disc are arranged at intervals, the bottom surface of an upper hinge is provided with a first limiting circular groove corresponding to the first limiting disc, the first limiting disc is arranged in the first limiting circular groove, the upper end surface of a lower hinge is provided with a second limiting circular groove corresponding to the second limiting disc, the second limiting disc is arranged in the second limiting circular groove, an annular groove is formed in the lower bottom surface of the lower hinge, a sealing ring and a clamping ring are arranged on the groove, oil storage grooves are formed in the inner hole walls of the upper hinge and the lower hinge respectively, and lubricating grease is filled in the oil storage grooves.

The utility model discloses a different adjustments can be made to casement aperture to spacing groove or vice spacing inslot through the screw is alternative precession, satisfies user's different demands, can prevent the risk of falling object simultaneously.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

FIG. 2 is a perspective view of a lower hinge according to an embodiment of the present invention;

fig. 3 is a cross-sectional view of an embodiment of the present invention.

Detailed Description

The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-3, the embodiment discloses an inward-opening inward-falling hinge, which includes an upper hinge 1 connected with a window sash and a lower hinge 2 connected with a window frame, the upper hinge 1 and the lower hinge 2 are sleeved on a rotating shaft 3, an arc-shaped limiting groove 4 is arranged on the outer wall of the rotating shaft 3 at a position corresponding to the upper hinge 1, one or more arc-shaped auxiliary limiting grooves 41 with step-shaped length are further arranged at the bottom of the limiting groove 4, a screw 5 is screwed on the upper hinge 1, a counter bore for the screw 5 to pass through is arranged on the upper hinge 1, so that the cap of the screw 5 can be placed in the counter bore, the surface is smoother, of course, screws 5 with different lengths can be selected according to the required opening degree of the window sash, so that the end of the screw 5 can be screwed into the limiting groove 4 and one or more auxiliary limiting grooves 41, one auxiliary limiting groove 41 shown in fig. 1 is one, and in fact, several auxiliary limiting grooves can be arranged according to, the limiting groove 4 and the auxiliary limiting groove 41 are arranged along the length direction of the rotating shaft.

One side wall of the limiting groove 4 and one side wall of the secondary limiting groove 41 are on the same straight surface. Therefore, the other side of the limiting groove 4 is stepped, so that the mounting position of the screw 5 is better selected and the processing is more convenient.

Be equipped with first spacing disc 31 and the spacing disc 32 of second on pivot 3, first spacing disc 31 and the spacing disc 32 interval of second set up, it is equipped with the first spacing circular slot 11 corresponding with first spacing disc 31 to go up 1 bottom surface of hinge, first spacing disc 31 is arranged in first spacing circular slot 11, lower 2 up end of hinge is equipped with the spacing circular slot 21 of second corresponding with the spacing disc 32 of second, the spacing circular slot 21 of second is arranged in to the spacing disc 32 of second, be equipped with annular recess 22 on lower bottom surface of lower hinge 2, and dispose sealing washer 6 and snap ring 7 on this recess 22, be equipped with oil storage tank 8 on the interior pore wall of last hinge 1 and lower hinge 2 respectively, oil storage tank 8 intussuseption is filled with lubricating grease. The structure can ensure that the upper hinge 2 and the lower hinge 2 rotate more smoothly, and simultaneously ensures that lubricating grease cannot overflow and prolongs the service life of the lubricating grease.

By adopting the technical scheme, the screw 5 can be selectively screwed into the limiting groove 4 or the auxiliary limiting groove 41 to adjust the opening degree of the window sash differently, so that different requirements of a user are met, and meanwhile, the risk of falling objects from high altitude can be prevented.

It should be noted here that, because the window sash will generate a large force to the screw when swinging, which damages the inside of the limiting groove or the secondary limiting groove, several hinges should be installed as much as possible according to the size of the window during installation, and two hinges should be installed on a small window, so that the force is reasonably dispersed to improve the reliability of the structure.
