background

Hinges, also known as hinges, are mechanical devices used to receive two solids and allow rotation between them. The hinge is made of a movable component or is made of foldable material. The hinge is widely used in daily life, such as doors and windows, various furniture and the like, and is also used in various mechanical devices. The material is mainly metal and can be divided into a stainless steel hinge and an iron hinge. These hinges have a feature that they cannot fixedly connect two objects by their own structure, that is, the two objects connected by the hinge can always rotate relative to each other and cannot be kept relatively still against an external force.

Further, the sleeve lateral wall is equipped with the screw hole, threaded hole is equipped with positioning bolt, positioning bolt is used for fixed connection first connecting rod lower extreme with the sleeve.

Further, the first connecting rod and the second connecting rod have the same diameter, and the inner diameter of the sleeve is equal to the diameter of the first connecting rod.

Further, the chute is an oval chute which is vertically arranged, and the diameter of the rotating shaft is equal to or smaller than the length of a short shaft of the chute.

Further, the lower end of the second connecting rod is inserted into the lower end of the sleeve and fixedly connected by a rivet.

further, when the rotating shaft slides to the lowest end of the sliding groove, the lower end of the first connecting rod is in contact with the upper end of the second connecting rod.

The embodiment of the utility model provides a beneficial effect that technical scheme brought is: the utility model discloses a hinge that can fix sets up the spout on the sleeve, pivot cooperation on spout and the first connecting rod makes the hinge have two kinds of operating condition, one kind is rotatable state, the pivot slides to spout upper portion this moment, first connecting rod lower extreme rises to in the connecting portion, first connecting rod can revolute the axle free rotation, another kind is the lock state of dying, the pivot slides to the spout lower part this moment, first connecting rod lower extreme inserts in the sleeve, receive telescopic restraint, first pivot can't rotate, make first connecting rod can keep static under the condition of resisting external force.

Detailed Description

in order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a fixable hinge, including a sleeve 1, a first link 2 and a second link 3.

Sleeve 1 is the hollow cylinder sleeve, and its upper end is U-shaped connecting portion 4, connecting portion 4 by 1 top surface of sleeve excises two vaulted posts downwards and forms, connecting portion 4 has relative both sides face, each the side is equipped with a spout 5, two spout 5 sets up relatively, in this embodiment spout 5 is the oval spout of vertical setting, 1 lateral wall of sleeve is equipped with screw hole 7 and rivet hole 8, screw hole 7 set up in rivet hole 8 top, just be equipped with positioning bolt 9 in the screw hole 7.

2 outer walls of first connecting rod are equipped with relative two pivots 6, 6 diameters in pivot are equal to or less than the length of 5 minor axes of spout, first connecting rod 2 with 3 diameters of second connecting rod are the same, just the internal diameter of sleeve 1 equals the diameter of first connecting rod 2, 3 lower extremes of second connecting rod insert 1 lower extreme of sleeve just rivet 8 department is with rivet 10 fixed connection, insert 2 lower extremes of first connecting rod in connecting portion 4, and two pivot 6 sets up respectively in two in the spout 5, pivot 6 can be along spout 5 slides from top to bottom, makes 2 lower extremes of first connecting rod are in slide in connecting portion 4.

the hinge has two working states, one is a rotatable state, the rotating shaft 6 slides to the upper part of the sliding chute 5, the lower end of the first connecting rod 2 rises into the connecting part 4, and the first connecting rod 2 can freely rotate around the rotating shaft between two opposite side surfaces of the connecting part 4; the other is a locked state, at this time, the rotating shaft slides to the lower part of the sliding groove, the lower end of the first connecting rod is inserted into the sleeve, because the lower end of the first connecting rod 2 is restrained by the upper end of the sleeve 1, the first connecting rod 2 cannot rotate in a plane, so that the first connecting rod 2 can keep static under the condition of resisting external force, the lower end of the first connecting rod 2 and the sleeve 1 can be fixedly connected by screwing the positioning bolt 9, and thus the first connecting rod 2 and the second connecting rod 3 are connected into a straight rod, and in order to ensure the strength of the straight rod, the lower end of the first connecting rod 2 is contacted with the upper end of the second connecting rod 3 when the rotating shaft 6 slides to the lowest end of the sliding groove 5.

In this document, the terms front, back, upper and lower are used to define the components in the drawings and the positions of the components relative to each other, and are used for clarity and convenience of the technical solution. It is to be understood that the use of the directional terms should not be taken to limit the scope of the claims.

The features of the embodiments and embodiments described herein above may be combined with each other without conflict.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
