Description

Metal hinge

[ technical field ] A method for producing a semiconductor device

The utility model relates to a building material field specifically is a metal hinge.

[ background of the invention ]

The hinge is a mechanical device used for connecting two solids and allowing the two solids to rotate relatively, and is mainly installed on doors and windows. In some public places, such as toilets in public places like shopping malls, stations, office buildings and the like, the door is easy to damage due to large flow of people and high opening and closing frequency of the door, a common hinge is connected with a door plate and a door frame through a screw, the connection part of the screw and the door plate or the hinge is deformed after long-time use, the environment of the area is wet, and the door plate is easy to deform and damage. However, the hinge as a whole is mounted during the installation process by first mounting one of the vanes on the door frame and then mounting the door panel, which often cannot be perfectly aligned during the installation of the door panel, resulting in a tilting of the door panel relative to the door frame and thus in a more likely way in the deformation of the hinge.

It can be seen that providing a deformation resistant metal hinge is a problem that needs to be addressed in the art.

[ Utility model ] content

To the above problem, the utility model discloses metal hinge is convenient for install and dismantle through the split type design of upper and lower hinge, can prevent the deformation of hinge and door plant or door frame junction through bolt and sleeve, and the sleeve can satisfy the door plant use of different thickness with the connected mode of bolt, through the design of the screw thread post on the connector, even the high slight error of hinge installation from top to bottom can not cause the deformation yet a bit.

In order to solve the problem, the utility model discloses metal hinge includes hinge, lower hinge, is used for connecting connector, a plurality of bolt and the sleeve of hinge and lower hinge, wherein goes up the hinge and installs on the door plant, and lower hinge is installed on the door frame, go up the hinge and seted up the decurrent recess of opening, the ascending internal thread hole of opening is seted up to lower hinge, the connector includes the hexagonal prism in upper portion and the screw thread post of lower part, the hexagonal prism inserts in the recess of last hinge, the screw thread post passes through screw thread rotatable coupling in the internal thread hole.

Further, go up the hinge and all seted up hexagonal countersunk head on the hinge down, the bolt is outer hexagonal bolt, and its screw rod passes hexagonal countersunk head and inserts in door plant or the door frame, the sleeve includes circular shape head and screwed pipe, and wherein the head is offered the cross recess that is used for inserting the screwdriver, and wherein the screwed pipe stretches into door plant or the inside screw rod connection of being connected of door frame.

Furthermore, the utility model discloses metal hinge is convenient for install and dismantle through the split type design of upper and lower hinge, can prevent the deformation of hinge and door plant or door frame junction through bolt and sleeve, and the sleeve can satisfy the door plant use of different thickness with the connected mode of bolt, through the screw thread post design on the connector, even the height of hinge installation from top to bottom slightly error can not cause the deformation yet.

Fig. 1 is a schematic structural view of a metal hinge of the present invention.

Fig. 2 is a schematic view of the installation of the metal hinge of the present invention.

[ detailed description ] embodiments

The directional terms of the present invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", etc., are only directions in the drawings, and are only used for explaining and explaining the present invention, but not for limiting the scope of the present invention.

Referring to fig. 1 and 2, the metal hinge of the present invention is a hinge, and includes an upper hinge 1, a lower hinge 2, a connector 3 for connecting the upper hinge and the lower hinge, a plurality of bolts 4, and a sleeve 5. The upper hinge 1 is provided with a hexagonal counter bore 101 and a groove with a downward opening, and the cross section of the groove is in a regular hexagon shape. The lower hinge 2 is also provided with a hexagonal countersunk hole 101 and an internal threaded hole 201 with an upward opening. The connector 3 comprises two sections, namely a hexagonal prism 301 on the upper portion and a threaded column 302 on the lower portion, wherein the hexagonal prism is inserted into a groove of the upper hinge, and the threaded column is connected into the internal thread round hole 201 through threads. The bolt 4 is an outer hexagon bolt, the bolt head of the bolt is embedded in the hexagon countersunk head hole 101, and the screw rod penetrates through the upper hinge, the lower hinge, the door plate and the door frame. The sleeve 5 comprises a circular head 501 and a threaded pipe 502, wherein the head 501 is provided with a cross-shaped groove for inserting a screwdriver, and the threaded pipe 502 extends into a door plate or a door frame to be connected with a screw. When the door is installed, a through hole for the screw rod and the threaded pipe to pass through is formed in the door plate, the screw rod of the bolt 4 passes through the hexagonal counter bore 101 of the upper hinge 1 and the through hole in the door plate, and then the sleeve 5 is inserted from the inner side of the door plate and connected with the screw rod. And then, in the same way, the lower hinge 2 is installed on the door frame, then the connector 3 is connected into the internal threaded hole 201 of the lower hinge through the threaded column 302, and finally the upper hinge on the door panel is sleeved on the hexagonal prism 301 of the connector 3 through the groove with the downward opening. When the door panel is detached, the door panel can be detached only by lifting the door panel upwards and separating the upper hinge 1 from the connector 3. The upper and lower hinges can be removed from the door panel or door frame by screwing the top 501 of the sleeve with a screwdriver. The utility model discloses the metal hinge is convenient for install and dismantle through the split type design of upper and lower hinge, can prevent the deformation of hinge and door plant or door frame junction through bolt and sleeve, and the sleeve can satisfy the door plant use of different thickness with the connected mode of bolt, through the screw thread post design on the connector, even the height of hinge installation from top to bottom can not cause the deformation through the connector adjustment a little error.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
