Description

Technical Field

[0001] This invention relates to the field of fencing technology, and more particularly to an angle-adjustable pole fence. Background Technology

[0002] Regarding the pit problem during the maintenance of dam water valves, it is essential to ensure the safety of the area around the dam before carrying out maintenance to prevent external accidents. During maintenance, attention must be paid to the support of the pit walls to prevent collapse and safety accidents, as well as the protection around the pit to prevent outsiders from accidentally falling into the pit and to prevent damage to the pit. After maintenance is completed, debris and soil in the pit should be removed in a timely manner to restore the site environment.

[0003] Fences play a crucial safety role during the maintenance of dam valves, ensuring a safe working environment and effectively isolating the work area to protect maintenance personnel and those nearby. Existing fences typically use plug-in or bolt connections, with posts joined at 90° or 180° angles and running in straight lines. However, in practical applications, the irregular shapes of the pit openings and the non-straight edges of the pits often prevent fences from being erected along the pit boundaries. Instead, they are usually arranged in a rectangle, requiring excessive posts and fences and significantly occupying public space. Summary of the Invention

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1 Reference Figures 1-8 The first embodiment of the present invention provides an angle-adjustable pole fence, including a fence assembly 100 and a connecting assembly 200. The fence assembly 100 is used to delineate the boundary of the protected area and separate the protected area from other areas. It includes poles 101 arranged around the perimeter of the protected area. A barrier 102 is provided between two adjacent poles 101. The barrier 102 serves to separate and also to provide privacy protection within the protected area.

[0032] Furthermore, the connecting assembly 200 is used to connect the upright post 101 and the enclosure component 102 to assemble the fence. It includes a connecting post 201, with two symmetrical movable blocks 202 movably disposed at both ends of the connecting post 201. The movable block 202 has a drum-shaped receiving cavity 202a inside, and a drum-shaped rotating component 203 is movably disposed in the receiving cavity 202a. The end of the movable block 202 has an adjustment groove 202b that intersects with the receiving cavity 202a. A swing rod 204 is movably disposed in the adjustment groove 202b. One end of the swing rod 204 extends into the receiving cavity 202a and is fixedly connected to the rotating component 203. The other end of the swing rod 204 extends out of the movable block 202 and is provided with a locking bolt 205 for connecting the enclosure component 102.

[0033] Furthermore, the upright 101 has two symmetrical elongated holes 101a at both ends, and an installation component 300 for fixing the connecting post 201 is installed in the elongated holes 101a.

[0034] Specifically, the enclosure 102 includes two parallel enclosure rods 102a that are perpendicular to the uprights 101, and a barrier cloth 102b disposed between the two enclosure rods 102a. The end of the enclosure rod 102a near the uprights 101 is provided with a threaded groove that is compatible with the locking bolt 205.

[0035] Specifically, in use, firstly, the protected area is demarcated, and the uprights 101 are evenly arranged on the demarcated boundary line. Then, by cooperating with the mounting component 300 and the connecting post 201, the connecting post 201 is fixed in the elongated hole 101a, that is, the installation of the connecting component 200 is completed. Next, the end of the fence 102a with the threaded hole is threadedly connected to the locking bolt 205 to complete the installation of the fence 102a. After installation, the two fences 102a are parallel to each other and perpendicular to the uprights 101. Finally, the two ends of the barrier 102b are put over the outside of the fence 102a to complete the fence arrangement. The fence after the arrangement can effectively separate the protected area from the external area. At the same time, by setting the barrier 102b, the protected area can be shielded.

[0036] Furthermore, a positioning shaft 206 is provided at the center of the bottom surface of the accommodating cavity 202a, a positioning groove 203a adapted to the positioning shaft 206 is provided at the bottom of the rotating component 203, and a prism 203b arranged coaxially with the positioning groove 203a is provided at the top of the rotating component 203, and a prism 207 is inserted into the prism 203b.

[0037] Furthermore, the movable block 202 is provided with a screw hole 202c that is perpendicular to the accommodating cavity 202a at the corresponding prism hole 203b. An adjustment screw 208 is provided in the screw hole 202c. One end of the adjustment screw 208 extends into the accommodating cavity 202a and is fixedly connected to the end of the prism hole 203b. The other end of the adjustment screw 208 extends out of the movable block 202 and is provided with a standard internal hexagonal groove 208a.

[0038] Furthermore, the movable block 202 is provided with a protractor 209 on its exterior, and the end of the angle adjusting screw 208 is provided with a pointer 210, which points to the scale line of the protractor 209.

[0039] Furthermore, a gap is provided between the top of the rotating part 203 and the top surface of the accommodating cavity 202a, and a first spring 211 is sleeved on the outside of the adjusting screw 208. One end of the first spring 211 abuts against the prism 207, and the other end of the first spring 211 abuts against the top surface of the accommodating cavity 202a.

[0040] Specifically, when setting up the fence, it is installed according to the boundary outline of the protected area. After installation, the included angle of the fence 102a on both sides of each upright 101 is different. That is, the fence 102a needs to be adjusted according to the boundary outline of the protected area during installation, and the horizontal included angle between the fence 102a and the upright 101 needs to be adjusted.

[0041] That is, insert one end of the Allen wrench into the standard Allen socket 208a at the end of the adjusting screw 208, turn the wrench to drive the adjusting screw 208 to rotate, and then drive the prism 207 to rotate; further, the prism 207 drives the rotating part 203 to rotate, that is, drives the swing rod 204 to rotate. The swing rod 204 deflects along the adjusting groove 202b with the center of the rotating part 203 as the axis. The swing rod 204 moves away from the rotating part 203 and is connected to the surrounding rod 102a through the locking bolt 205; that is, the surrounding rod 102a deflects synchronously with the swing rod 204, adjusting the horizontal angle between the surrounding rod 102a and the upright rod 101.

[0042] During the adjustment process, the pointer 210 rotates synchronously with the screw and points to the scale line of the angle measuring disk 209, thereby enabling a more accurate determination of the adjustment angle. In this embodiment, the angle adjustment groove 202b starts from the end center of the movable block 202, extends to one side along the horizontal axis of the movable block 202, and ends at the middle of one side of the movable block 202. That is, the retaining rod 102a can achieve an angle adjustment of 0° to 90°, which is suitable for various irregular boundaries. When the angle adjustment screw 208 is threaded into the screw hole 202c, it will move up and down. The gap between the top of the rotating part 203 and the top surface of the accommodating cavity 202a can provide space for the prism 207 to move when the angle adjustment screw 208 moves up and down.

[0043] Example 2 Reference Figure 5 , Figure 8 and Figure 9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the end of the movable block 202 away from the angle adjustment groove 202b is provided with a cylindrical groove 202d that is consistent with the end contour of the connecting column 201, and the end of the connecting column 201 is inserted into the cylindrical groove 202d. The side wall of the cylindrical groove 202d is provided with a through arc-shaped groove 202e along the circumferential direction, and an anti-detachment block 212 is movably disposed in the arc-shaped groove 202e.

[0044] Furthermore, one end of the anti-detachment block 212 is fixedly connected to the connecting post 201, and the other end of the anti-detachment block 212 is provided with an arc-shaped locking plate 213. The arc-shaped locking plate 213 is provided with two symmetrical locking grooves 213a on one side of the outer curved surface of the movable block 202. Two symmetrical sliding grooves 202f are provided on the outside of the movable block 202 and near the two ends of the arc-shaped groove 202e. A sliding post 214 is provided in the sliding groove 202f. One end of the sliding post 214 extends to the outside of the movable block 202 and can be inserted into the locking groove 213a. A second spring 215 is provided between the other end of the sliding post 214 and the bottom of the sliding groove 202f.

[0045] Furthermore, the outer wall of the upright 101 is provided with a storage groove 101b that extends along the length direction and communicates with the elongated hole 101a. The storage groove 101b is used to store the surrounding rod 102a.

[0046] Specifically, by placing the anti-detachment block 212 into the arc-shaped groove 202e, the connecting post 201 and the movable block 202 can be prevented from separating. The anti-detachment block 212 can slide along the arc, that is, the movable block 202 can rotate to adjust the angle adjustment groove 202b to the vertical position. At this time, when the angle adjustment screw 208 is turned with an Allen wrench, it will drive the surrounding rod 102a to deflect longitudinally, so that the surrounding rod 102a rotates and is placed into the storage groove 101b, saving storage space.

[0047] The remaining structure is the same as that in Example 1.

[0048] Example 3 Reference Figure 2 and Figure 3 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a through mounting groove 201a is provided in the middle of the connecting post 201, and the mounting assembly 300 includes a support base 301 disposed at the bottom of the elongated hole 101a, and fastening corner pieces 302 for fixing the connecting post 201. The top of the support base 301 is inserted into the mounting groove 201a, and there are two fastening corner pieces 302 arranged symmetrically above the connecting post 201.

[0049] Specifically, the connecting column 201 can be supported by the support base 301, and the connecting column 201 can be locked by the fastening corner piece 302, thereby limiting the connecting column 201 in multiple directions and realizing the rapid fixed installation of the connecting column 201.

[0050] The remaining structure is the same as that in Example 2.
