[0002] Hinges are common mechanical connectors used in a wide range of applications, including homes, transportation, and machinery. They connect two objects and allow them to move relative to each other in one or more directions. Fence and gate pivot hinges are a type of hinge, commonly used on outdoor fences and gates.

[0003] Unlike doors like house doors and security doors, which have relatively uniform specifications, fence doors vary in shape and size, and the gaps between the door and the doorframe vary. A single hinge is difficult to adapt to all types of fence doors, resulting in the need for a variety of hinges, which is inconvenient for users. Furthermore, because fence doors are mostly inexpensive wooden doors and are installed outdoors, exposed to wind and rain, traditional screw-only installation methods can easily loosen, causing the fence door to tilt and affect its normal use.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, an adjustable fence gate pivot hinge includes component No. 1 and component No. 2, both of which are composed of a fixed plate 3, a movable plate 4, and a rotating plate 5. The surfaces of the fixed plate 3, the movable plate 4, and the rotating plate 5 are provided with a plurality of mounting holes 6 for mounting them to the fence gate using screws. Component No. 1 and component No. 2 have the same basic structure, except that the components provided on the surface of the fixed plate 3 are different. The fixed plate 3 is a right-angled L-shaped structure, and the connecting ear 7 and the fixed plate 3 are an integral structure formed by stamping and bending. The two connecting ears 7 are arranged horizontally, and a through-hole 8 is also provided on their surface. The surface of the fixed plate 3 in the second component 2 is also stamped and bent to form two mounting blocks 15. The two mounting blocks 15 are arranged in a property, and a shaft pin 16 is movably installed between the two mounting blocks 15. The outer rotation of the shaft pin 16 is connected to a rotating sleeve 17. The connecting rod 18 is vertically welded and installed on the surface of the rotating sleeve 17. The middle part of the connecting rod 18 is a plain rod, and the two ends are threaded rods, and each threaded rod is equipped with a fixing nut 19. The connecting rod 18 is connected to the connecting ear 7 to form a hinge structure between the first component 1 and the second component 2.

[0023] like Figure 2-Figure 3As shown, a telescopic tube 9 is provided on the fixed plate 3, and a telescopic rod 11 is installed on the movable plate 4. The telescopic rod 11 is movably connected to the telescopic tube 9, movably connecting the fixed plate 3 and the movable plate 4 together and allowing for telescopic adjustment. The rotating plate 5 is rotatably connected to the other side of the movable plate 4 and can be rotated and adjusted about the vertical axis. The telescopic tube 9 and the fixed plate 3 are an integrated structure. The surface of the movable plate 4 is provided with an integrated connector 10. The end of the connector 10 is fixedly mounted with a telescopic rod 11. The outside of the telescopic rod 11 is sheathed with a connecting spring 12. The telescopic rod 11 and the connecting spring 12 extend into the telescopic tube 9 together. The two ends of the connecting spring 12 are fixedly connected to the inner bottom surface of the telescopic tube 9, and the other end is fixedly connected to the end surface of the connector 10.

[0024] In this embodiment, the movable plate 4 is provided with a groove on the other side of the corresponding connecting head 10, and a pair of rotating sleeves 13 are fixedly installed in the groove. The rotating sleeves 13 are arranged up and down, leaving an installation gap in the middle. A raised portion is correspondingly provided at the side end of the rotating plate 5, and a rotating shaft 14 is fixedly installed on the raised portion, and the rotating shaft 14 is rotatably installed in the rotating sleeve 13.

[0025] In actual use, first arrange component 1 and component 2 symmetrically, install one on the door leaf of the fence gate, and the other on the door frame. First, use screws to fix the front of the fixing plate 3 of the two components, and then choose different installation methods according to the width of the door leaf and door frame:

[0026] When the width of the door leaf and door frame is less than or equal to the width of the right-angled side of the fixing plate 3, it is only necessary to fix the mounting holes 6 on the right-angled side of the fixing plate 3. However, from the perspective of installation stability, it is recommended to choose the smaller No. 1 component 1 and No. 2 component 2.

[0027] When the width of the door leaf and door frame is greater than the width of the right-angled side of the fixed plate 3, until it is greater than the width of the right-angled side of the fixed plate 3 plus the width of the movable plate 4, then you only need to pull the movable plate 4 outwards. Since the telescopic rod 11 fixedly installed on the side of the movable plate 4 is fixedly connected to the telescopic tube 9 on the right-angled side of the fixed plate 3 by the connecting spring 12, a longitudinally limited elastic telescopic adjustment structure is formed. When the movable plate 4 is pulled until its side is flush with the door leaf and door frame, you only need to rotate the rotating plate 5 so that it sticks to the back of the door leaf and door frame and fix it with screws. The contraction force of the connecting spring 12 pulls the movable plate 4 back, so that the fixed plate 3, movable plate 4 and rotating plate 5 form a C-shaped wrapping structure that tightly wraps the edges of the door leaf and door frame. You only need to fix the movable plate 4 with screws to complete the installation and fixation of the component. Specific installation examples are as follows: Figure 4 As shown in FIG. , this structure is applicable to a wide range of fence and fence door sizes due to the telescopic structure of the movable plate 4, and there is no need to specifically design components of various sizes.

[0028] When the width of the door leaf and door frame is large enough, larger than the sum of the widths of the right-angled side of the fixed plate 3, the extended (adjusted) movable plate 4 and the rotating plate 5, or when the back of the door leaf and door frame is not suitable for installing the rotating plate 5, it is only necessary to rotate the rotating plate 5 to be flush with the movable plate 4, and then fix the right-angled side of the fixed plate 3, the movable plate 4 and the rotating plate 5 in turn. The specific installation example is as follows Figure 5 As shown, the extended side is fixed at multiple points, which can also improve the installation firmness of the components and is also suitable for the installation of fence gates of various sizes.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
