Description

Technical Field

[0001] This utility model relates to the field of fence technology, and more specifically, to an easy-to-install fence. Background Technology

[0002] As a common basic protective facility, fencing is widely used in municipal engineering, agriculture and animal husbandry, construction site isolation, and private courtyards. Traditional fencing typically consists of posts, beams, and a mesh structure, and is usually installed using bolt fastening. Specifically, the posts are pre-fixed to the ground, and the two ends of the beams are aligned with the pre-drilled holes on the posts on both sides and then tightened one by one, ultimately fixing the fencing to the beams or posts.

[0003] While this type of structure has a certain degree of stability, its installation efficiency is relatively low in actual construction. Each connection point requires multiple bolts (usually 4-6), and workers need to repeatedly drill holes, insert bolts, and tighten nuts. This is especially time-consuming and labor-intensive when installing multiple fence nets consecutively, so it needs to be improved. Utility Model Content

Detailed Implementation

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-4 This embodiment will be described in further detail.

[0023] Please see Figures 1-4 This embodiment of an easy-to-install fence includes a fence frame 100, a mesh screen 101 on the fence frame 100, a front upright plate 102 and a rear upright plate 103 respectively arranged opposite to each other on both sides of the fence frame 100, sliders 104 at the four corners of the fence frame 100, grooves 105 for sliding of the sliders 104 on both sides of the upper and lower ends of the front upright plate 102, a limiting plate 106 arranged opposite to each other between the front upright plate 102 and the rear upright plate 103, a plurality of retractable locking rods 107 evenly spaced along the vertical direction on the limiting plate 106, locking holes 108 for the locking rods 107 to extend or disengage on both sides of the fence frame 100 corresponding to the locking rods 107, a locking assembly for driving the locking rods 107 to extend and retract between the limiting plates 106, a cover plate 109 between the upper and lower ends of the front upright plate 102 and the rear upright plate 103, and a height-adjustable fixing seat 110 on the lower cover plate 109.

[0024] In this embodiment, the barrier net 101 is fixedly connected to the fence frame 100 to form a fence net, the slider 104 is slidably connected to the slide groove 105, the limiting plate 106 is fixedly connected between the front upright plate 102 and the rear upright plate 103, and the cover plate 109 is fixedly connected to the front upright plate 102 and the rear upright plate 103.

[0025] In this embodiment, the fixing base 110 is provided with a reserved hole so that the fixing base 110 can be fixed to the ground by expansion bolts. When installing the fence, first fix the fixing base 110 to the ground, then align the sliders 104 at the four corners of the fence frame 100 with the corresponding slide grooves 105, and push the fence frame 100 to pre-install the fence frame 100 between the front upright plate 102 and the rear upright plate 103 on both sides. Then, control multiple locking rods 107 to simultaneously extend into the corresponding locking holes 108 through the locking assembly to complete the installation of the fence.

[0026] In this embodiment, the locking component can control multiple locking rods 107 to simultaneously extend into or disengage from the corresponding locking holes 108, avoiding the need for manual repeated hole alignment, bolt insertion, and nut tightening 403, making the operation simple, time-saving, and labor-saving.

[0027] In this embodiment, the height of the slide 105 is greater than the thickness of the slider 104, so that the fence frame 100 has space to move up and down. At the same time, the size of the opening of the locking hole 108 is greater than the diameter of the locking rod 107. When there is a slight height difference between the front upright plate 102 and the rear upright plate 103 on both sides of the fence frame 100, the locking rod 107 can also be locked into the locking hole 108.

[0028] Please see Figures 1-4 In this embodiment, the locking assembly includes a cylindrical tube 200 with openings at both ends, which is disposed on the limiting plate 106. A locking rod 107 is disposed inside the cylindrical tube 200. A cap 201 is provided at the open end of the cylindrical tube 200 away from the limiting plate 106. One end of the locking rod 107 extends through the cap 201. A vertical cavity 202 is formed between the limiting plates 106. The other end of the locking rod 107 extends through the limiting plate 106 into the vertical cavity 202. A stop ring 203 is provided on the surface of the locking rod 107 located on the limiting tube. A spring 204 is sleeved on the locking rod 107 to push the stop ring 203 between the cap 201 and the stop ring 203.

[0029] In this embodiment, the cylindrical tube 200 is fixedly connected to the limiting plate 106, and the plug cap 201 is threadedly connected to the cylindrical tube 200 so as to install the components inside the cylindrical tube 200. The abutment ring 203 is fixedly connected to the locking rod 107. The abutment ring 203 is pushed by the spring 204, and the abutment ring 203 pushes the locking rod 107 so that the locking rod 107 can move away from the locking hole 108 and be flush with the plug cap 201, so that the pre-installation of the fence frame 100 is not affected.

[0030] Please see Figures 1-4 In this embodiment, the vertical cavity 202 is provided with a movable extrusion block 300 located above the clamping rod 107. The lower part of both sides of the extrusion block 300 is provided with inclined surfaces 301, the upper part of both sides of the extrusion block 300 is provided with vertical surfaces 302, and the extrusion blocks 300 are provided with connecting rods 303.

[0031] In this embodiment, the extrusion block 300 is slidably connected in the vertical cavity 202, and the connecting rod 303 is fixedly connected to the extrusion block 300. Through the connection between the connecting rod 303 and the extrusion block 300, multiple extrusion blocks 300 can slide simultaneously.

[0032] When multiple locking rods 107 are simultaneously engaged in the locking holes 108, the pressing block 300 moves downward, pressing the pressing rods through the inclined surface 301, and compressing the spring 204 through the abutment ring 203, causing the locking rods 107 to move towards the locking holes 108. When the vertical surface 302 contacts the locking rods 107, the locking rods 107 can be fully engaged in the locking holes 108, completing the fixing of the fence net.

[0033] When the fence is damaged and needs to be replaced, the pressing block 300 can be moved upward, and under the action of the spring 204, multiple locking rods 107 can be disengaged from the locking holes 108, releasing the fence from its fixation so that it can be replaced.

[0034] Please see Figures 1-4 In this embodiment, the front upright plate 102 is provided with a square hole 304 corresponding to one of the extrusion blocks 300. The extrusion block 300 is provided with a connecting plate 305 extending along the square hole 304. The front upright plate 102 is provided with a cover 306 covering the square hole 304. The cover 306 is provided with a screw 307 that is threadedly connected to the connecting plate 305 and can rotate. One end of the screw 307 extends out from the top of the cover 306, and the end of the screw 307 extending out from the top of the cover 306 is provided with a rotating cap 308.

[0035] In this embodiment, the connecting plate 305 is fixedly connected to the extrusion block 300, the cover 306 is fixedly connected to the front upright plate 102, the lead screw 307 is rotatably connected to the cover 306, and the rotating cap 308 is fixedly connected to the top end of the lead screw 307. By rotating the rotating cap 308, the lead screw 307 can be driven to rotate. The rotation of the lead screw 307 can drive the connecting plate 305 to move up and down, thereby driving the extrusion block 300 to move up and down, and controlling the extension and retraction of the clamping rod 107.

[0036] Please see Figures 1-4 In this embodiment, a square sleeve 400 is provided on the lower end cover plate 109, and a sliding support rod 401 for installing the fixing seat 110 is provided inside the square sleeve 400.

[0037] In this embodiment, the square sleeve 400 is fixedly connected to the cover plate 109, and the fixing seat 110 is fixedly connected to the support rod 401. By sliding the support rod 401 within the square sleeve 400, the height of the fixing seat 110 can be adjusted to adapt to different ground heights. Alternatively, the heights of the front upright plate 102 and the rear upright plate 103 can be adjusted. When the height difference between the front upright plate 102 and the rear upright plate 103 on both sides of the fence frame 100 is large, adjusting the heights of the front upright plate 102 and the rear upright plate 103 on both sides of the fence frame 100 allows the locking rod 107 to engage with the locking hole 108.

[0038] Please see Figures 1-4 In this embodiment, an adjustment groove is provided on one side of the square sleeve 400, a threaded rod 402 extending along the adjustment groove is provided on the support rod 401, a rubber gasket is fitted on the threaded rod 402, and a limiting nut 403 is provided on the threaded rod 402.

[0039] In this embodiment, the threaded rod 402 is fixedly connected to the support rod 401. The rubber gasket is used to increase the friction between the nut 403 and the square sleeve 400 to better fix the height of the support rod 401. The height of the support rod 401 can be adjusted by tightening or loosening the nut 403, thereby adjusting the height of the fixed seat 110.

[0040] When using this utility model, during the installation of the fence, first fix the fixing base 110 to the ground, then align the sliders 104 at the four corners of the fence frame 100 with the corresponding sliding grooves 105, and push the fence frame 100 to pre-install the fence frame 100 between the front upright plate 102 and the rear upright plate 103 on both sides. Then rotate the rotating cap 308 to drive the pressing block 300 to move, thereby controlling the extension and retraction of the clamping rod 107, thereby installing or removing the fence.

[0041] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
