Detailed ways

The present application will be further described in detail below in conjunction with accompanying drawings 1-3.

1 and 2 , an embodiment of the present application proposes a convenient fence net device, including a fence net support 1 , a fence net 2 , and a support frame 3 disposed at the bottom end of the fence net support 1 and supported on the ground. The fence net support 1 is arranged vertically, and a cavity 11 is arranged inside to form a cavity structure, and a mounting hole 12 connecting the cavity 11 is opened laterally; The isolation belt retractor 14, the winding column 13 is arranged vertically, the top of the winding column 13 is rotatably connected to the fence net support 1, and the bottom end is fixed to the coil spring type isolation belt retractor 14, so as to realize the forced rotation of the winding column 13. The opposite side of the fence support 1 and the opening direction of the installation hole 12 is fixed with two hangers 15; the outer side of the fence support 1 is also vertically spaced with a plurality of positioning holes 16, and the positioning holes 16 The holes are slanted.

One end of the length direction of the fence net 2 penetrates into the cavity 11 from the installation hole 12 and is fixed to the winding column 13; The hooks 21 are placed at both ends of the fence net 2 in the width direction.

When setting the fence net, erect the fence net bracket 1 and support the support frame 3 on the ground; then by applying force to the hook 21, pull out the fence net 2 from the installation hole 12, and hang the hook 21 on another fence net The hanger 15 on the bracket 1 is enough; in this process, the pulled out fence 2 drives the winding column 13 to rotate; when recycling, just remove the hook 21, at this time, the coil spring type isolation belt retractor 14 returns In the initial state, the winding column 13 is driven to reverse, so that the fence net 2 is wound on the winding column 13, so that the fence net 2 is stored in the fence net bracket 1, so as to be used next time, improving the handling, assembly and disassembly of the fence net and the fence. In the process of mesh support, there are problems of heavy workload and low work efficiency.

Among them, the coil spring type isolation belt retractor 14 is the prior art known to those skilled in the art, such as: the retractable structure of the coil spring in the telescopic isolation belt and the tape measure, so here the coil spring type isolation belt retractor 14 The specific structure is not described.

1 to 3 , on the same horizontal plane, the opening width of the mounting hole 12 is smaller than the width of the hook 21 to prevent the hook 21 from entering the mounting hole 12 when the fence 2 shrinks.

And in the horizontal direction, the two even hole walls of the mounting hole 12 are formed with two necks 121 facing each other. The upper/lower inner walls form the spacing.

Both ends of the fence net 2 in the width direction are fixed with limiter wires 22 , and the limiter wires 22 are inserted between the neck 121 and the upper/lower inner walls of the installation hole 12 . When the fence net 2 is pulled out or retracted, the limit pull wire 22 is always restricted by the two necks 121 arranged opposite to each other, and passes in or out near the upper/lower inner walls of the installation hole 12, so that the fence net can be kept. 2 is neatly wound around the winding post 13, and the complete open state when the fence 2 is pulled out.

A sign 23 is provided on the fence net 2 for warning of danger. And the signboard 23 is coated with a fluorescent layer, so as to have a display function in a dark environment.

1 , the support frame 3 includes a movable ring 31, a fixed ring 32, a plurality of main support rods 33 and a plurality of auxiliary support rods 34; the movable ring 31 is slidably connected to the fence net bracket 1, and its lateral through openings are connected with The insertion hole 311 of the positioning hole 16, and the hole diameter of the insertion hole 311 is smaller than the hole diameter of the positioning hole 16, and the two holes are in the same direction; the movable ring 31 is also provided with a limit mechanism for restricting its downward sliding. The fixed ring 32 is slidably connected to the fence net support 1 and is lower than the movable ring 31 . The number of the plurality of main support rods 33 and the plurality of auxiliary support rods 34 is equal, and one end of the main support rod 33 is rotatably connected to the movable ring 31, and the two ends of the plurality of auxiliary support rods 34 are respectively rotatably connected to the fixed ring 32 and the main support rod. The middle position of the rod 33, and the rotation plane is a vertical plane.

Wherein, the limiting mechanism includes a positioning rod 4 that can be inserted into the connecting jack 311 and the positioning hole 16 at the same time.

When the fence support 1 is supported by the support frame 3, both the movable ring 31 and the fixed ring 32 can be slid downward, so that the fixed ring 32 is supported on the ground, and the movable ring 31 is limited by the positioning rod 4 to stop sliding, At this time, the main support rod 33 and the auxiliary support rod 34 are rotated and unfolded until the main support rod 33 is supported on the ground, thereby supporting the fence net support 1 and enhancing the stability of the fence net support 1 .

When not in use, slide the movable ring 31 and the fixed ring 32 upward, and limit the movable ring 31 by the positioning rod 4 until the support part of the main support rod 33 is off the ground, reducing the space occupied by the device.

Since the hole diameter of the insertion hole 311 is smaller than that of the positioning hole 16 , and the positioning rod 4 is arranged obliquely, the oblique insertion of the positioning rod 4 is more convenient and can prevent the positioning rod 4 from falling off.

A handle 312 is provided on the movable ring 31 to pull the movable ring 31.

An anti-skid pad 331 is provided at the support end of the main support rod 33 to increase stability.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application rather than limitations. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be Modifications or equivalent replacements without departing from the spirit and scope of the technical solutions of the present application should all be covered by the scope of the claims of the present application.
