Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a multi-piece fence with adjustable installation angle that can be spliced ​​together. Background Technology

[0002] Traditional fences are mostly single-piece structures, with both ends fixed to the door frame or wall. These fences cannot adjust the angle according to the installation environment and are difficult to adapt to different widths of installation positions or special installation needs. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, the present invention provides a multi-piece fence with adjustable installation angle that can be spliced ​​together.

[0004] The present invention provides a multi-panel fence with adjustable installation angle that can be spliced ​​together, using the following technical solution:

[0005] A multi-panel adjustable fence includes a door frame, a door body located at the center of the door frame, and uprights at both ends of the door frame. Each upright has an adjustable hinge mechanism at its end. One or more side panels are located on the side of the adjustable hinge mechanism furthest from the door frame. When there are multiple side panels, adjacent side panels are connected by a hinge connection assembly. Both the hinge connection assembly and the adjustable hinge mechanism have interlocking lower and upper connecting plates. Rotating the side panel allows the lower and upper connecting plates in the adjustable hinge mechanism and hinge connection assembly to change their interlocking positions, thereby adjusting and fixing the side panel's angle.

[0006] Furthermore, a side fixing component is provided at the end of the side rail away from the adjustable hinge mechanism. The side fixing component fixes the end of the railing in the required position. The specific structure of the side fixing component includes connecting parts and wall connecting rods. Connecting parts are symmetrically arranged at the upper and lower ends of the wall connecting rods. The connecting parts are connected to the side rail, so that the side fixing component is installed on the side of the side rail. A wall fixing seat is provided on the wall connecting rod. The wall fixing seat is fixedly connected to the side of the railing where it needs to be fixed by bolts. A foot pedal is also provided at the bottom of the door frame.

[0007] Furthermore, the adjustable hinge mechanism includes a connecting rod, with a hinge assembly at the upper end and a bottom hinge assembly at the lower end. The hinge assembly specifically includes a locking bolt and a lower connecting plate. The bottom of the locking bolt is fixedly connected to the top wall of the connecting rod, and a locking nut is fixedly installed on the outer wall of the bottom of the locking bolt. By rotating the locking nut, the locking bolt clamps and fixes the end of the connecting rod. A lower connecting plate is fixedly installed above the locking nut and is connected to the top of the riser. An upper connecting plate is also rotatably installed above the locking nut. A connecting end is installed on the side of the upper connecting plate away from the lower connecting plate, through which the hinge assembly is connected to the side rail. Multiple protrusions are evenly distributed around the center line of the upper connecting plate at its bottom, and multiple grooves are evenly distributed around the center line of the lower connecting plate at its upper part. The protrusions in the upper connecting plate engage with the grooves in the lower connecting plate, thereby fixing the position of the connecting end.

[0008] Furthermore, the specific structure of the bottom hinge assembly includes a lower fixed plate and an upper plate body. One end of the lower fixed plate is fixedly connected to the bottom of the connecting rod, and the other end of the lower fixed plate is fixedly connected to the bottom of the riser. The upper plate body is rotatably connected to the upper part of the lower fixed plate.

[0009] Furthermore, the sidebar is a wide sidebar, with an upper horizontal tube at the top and a lower horizontal tube at the bottom. Spring clips are located on the lower surfaces of both ends of the upper horizontal tube and on the upper surfaces of both ends of the lower horizontal tube. When the end of the upper horizontal tube is inserted into the connecting end, the spring clips in the upper horizontal tube engage with the side wall of the connecting end, thus forming a detachable connection between the upper horizontal tube and the upper connecting plate. A connecting seat is located on the side of the upper plate away from the lower fixed plate. When the end of the lower horizontal tube is inserted into the connecting seat, the spring clips in the lower horizontal tube engage with the side wall of the connecting seat, thus forming a detachable connection between the lower horizontal tube and the connecting seat.

[0010] Furthermore, the end of the upper horizontal tube furthest from the door frame is inserted into the connecting component at the top of the wall connecting rod. The upper horizontal tube engages with the side wall of the connecting component via a spring clip, thus forming a detachable connection between the upper horizontal tube and the connecting component. The connection method between the lower horizontal tube and the connecting component at the bottom of the wall connecting rod is the same as described above.

[0011] Furthermore, the side rail is a narrow side rail, which includes a T-joint connector and a vertical round tube. T-joint connectors are symmetrically arranged at the upper and lower ends of the vertical round tube. The top of each T-joint connector has a narrow side connecting rod, and a sleeve extends downwards from the bottom of the narrow side connecting rod. The end of the vertical round tube is fixedly connected to the sleeve. Spring buckles are provided on the bottom walls at both ends of the narrow side connecting rod. By inserting the narrow side connecting rod at the upper end of the vertical round tube into the connecting end, the spring buckles at the end of the narrow side connecting rod engage with the side wall of the connecting end, thus forming a detachable connection between the narrow side rail and the connecting end. By inserting the narrow side connecting rod at the bottom of the vertical round tube into the connecting seat, and engaging the spring buckles in the narrow side connecting rod with the side wall of the connecting seat, a detachable connection between the narrow side rail and the connecting seat is formed. The side of the narrow side connecting rod furthest from the door frame is inserted into the connecting component, and the spring buckles in the narrow side connecting rod engage with the side wall of the connecting component, thus detachably installing the side fixing component on the side of the narrow side rail.

[0012] Furthermore, the hinge connection assembly includes a central rod, an upper connector is disposed on the upper part of the central rod, and a lower connector is disposed at the bottom of the hinge connection assembly. The upper connector includes a hinge assembly and a connecting sleeve. The connecting sleeve is disposed on the side of the lower connecting plate in the hinge assembly. Spring-loaded buckles are disposed at both ends of the side rails. The upper ends of two adjacent side rails are respectively engaged with the connecting sleeve and the connecting end in the hinge assembly via the spring-loaded buckles. The lower connector includes a bottom connecting sleeve and an upper plate body. The bottom connecting sleeve is fixedly connected to the bottom of the central rod and is located at the bottom... The upper plate is rotatably mounted on the part of the connecting sleeve that connects to the central rod. The lower ends of the two adjacent side rails are respectively engaged with the bottom connecting sleeve and the upper plate via spring buckles. Multiple side rails are connected together by a hinge connection assembly to form a fence with multiple side rails. When the fence is formed into a horizontal or polygonal open shape, the outer ends of the side rails at both ends of the fence are provided with side fixing components. When the fence with multiple side rails is formed into a closed shape, the side rails at both ends of the fence are connected by a hinge connection assembly to form a closed structure.

[0013] Furthermore, a fixing structure is provided at the bottom of the adjustable hinge mechanism and the hinge connection assembly. The fixing structure is screwed to the bottom of the adjustable hinge mechanism and the hinge connection assembly, and the position of the bottom of the fence is fixed and supported by the fixing structure.

[0014] Furthermore, the fixing structure is one of a suction cup, an adhesive fastener, or a ground nail.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model provides an adjustable hinge mechanism between the riser and the side rail of the door frame, as well as a hinge connection assembly that connects multiple side rails. When the side rail is rotated, the lower and upper connecting plates in the adjustable hinge mechanism and the hinge connection assembly can change their engagement positions, thereby adjusting and fixing the side rail at an angle. The fence with this structure can adjust its angle according to the installation environment and can adapt to different widths of installation positions or special installation requirements.

[0017] 2. The adjustable hinge mechanism and the fixed structure at the bottom of the hinge connection assembly can fix and support the bottom of the fence, increasing the stability of the fence installation. Attached Figure Description
