The setting of security fences is for isolation on the one hand, and for closed management of local areas on the other hand, making management more convenient while avoiding theft and protecting the living safety of people in the area. However, the existing security fences have certain problems in actual use and still need continuous improvement.

[0003] Referring to a Chinese patent case with authorization announcement number CN220014730U, an insulating telescopic fence is disclosed, including a fence frame and a telescopic bar, the fence frame including a first fence frame and a second fence frame, an intermediate post is arranged between the first fence frame and the second fence frame, a first telescopic bar is installed between the first fence frame and the intermediate post, a second telescopic bar is installed between the second fence frame and the intermediate post, and one end of the first telescopic bar is connected to the first fence frame. The utility model enables the fence to achieve a 0°-180° turn and change direction during use through a first connecting member, a second connecting member, a third connecting member and a fourth connecting member. The fence frame and the intermediate post are filled with cement or insulating boards to improve the overall wind resistance of the fence. However, the first fence frame and the second fence frame in this case use scissor-type telescopic rods, which are also easy to pull the posts to shrink during use, and the overall stability needs to be improved.

[0004] Therefore, those skilled in the art provide a security fence to solve the problems raised in the above background technology. Utility Model Content

[0021] Specifically, a telescopic frame structure 3 is arranged between two adjacent main rods 1. The telescopic frame structure 3 can be retracted and extended, so as to adjust the spacing between adjacent columns and control the length of the fence. In order to ensure the overall stability of the fence after it is unfolded, an adjusting frame structure 4 is arranged on the adjusting rod 2. After the telescopic frame structure 3 is unfolded, the adjusting frame structure 4 can be moved to an appropriate length. After rotating the adjusting rod 2, the support bar 41 can be attached to the vertical strip 44, and the bolt rod 46 with the clamping plate 47 can be passed through the through groove 45 on the vertical strip 44. After rotating the clamping plate 47, the bolt rod 46 can be tightened with the threaded cooperation, so that the support bar 41 can be fixed on the vertical strip 44. Since the contraction displacement of the telescopic frame structure 3 and the adjusting frame structure 4 is different, the telescopic frame structure 3 can be restricted and locked, so as to maintain the overall stability of the fence.

[0022] Reference Figure 1 , Figure 2 As shown, the width of the clamping plate 47 is smaller than the width of the through slot 45, and the length of the clamping plate 47 is larger than the width of the through slot 45. The adjustment frame structure 4 also includes at least two supporting links 42, and both ends of the supporting links 42 are hingedly mounted with supporting hinge sleeves 43, and the two supporting hinge sleeves 43 on both ends of the supporting links 42 are respectively mounted on the adjusting rod 2 and the supporting bar 41;

[0023] In addition, the support hinge sleeves 43 at both ends of the support link 42 are respectively installed on the adjusting rod 2 and the support bar 41, so that the support bar 41 must be retracted by rotating the support link 42, and the column shrinks and compresses the two telescopic links 32 and can slide horizontally after being squeezed. The displacement paths of the two are different. After the support bar 41 and the vertical strip 44 cooperate, the contraction between the columns can be limited.

[0024] Reference Figure 1 , Figure 2 As shown, support seats 11 are provided on the bottom and top of the column, the main rod 1 is fixedly installed between the upper and lower support seats 11, the adjusting rod 2 is rotatably installed between the upper and lower support seats 11, and two universal rollers 12 are installed in parallel at the bottom of the bottom support seat 11, and the support seats 11 at the bottom of the two columns at the edge are also pierced with anchor rods 13 for fixing. The support seats 11 are provided to facilitate the connection between the main rod 1 and the adjusting rod 2, and the anchor rods 13 are also provided to facilitate the fixing of the columns at the edges.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] The implementation principle of a security fence in this application is:

[0028] When in use, first place the fence on the ground, then use the anchor rod 13 to pass through the support seat 11 to fix the column at one end of the edge on the ground, pull the column at the other end of the edge to unfold the fence for maintenance, at this time the telescopic frame structure 3 will be unfolded to facilitate the elongation of the fence. In order to ensure the overall stability of the fence after unfolding, an adjusting frame structure 4 is provided on the adjusting rod 2. After the telescopic frame structure 3 is unfolded, the adjusting frame structure 4 can be moved to a suitable length. After the adjusting rod 2 is rotated, the support bar 41 can be attached to the vertical strip 44, and the bolt rod 46 with the clamping plate 47 can be fixed. By passing through the through slot 45 on the vertical strip 44 and rotating the clamping plate 47, the bolt rod 46 is tightened under the cooperation of the thread, so that the support bar 41 can be fixed on the vertical strip 44. The support bar 41 is installed on the adjusting rod 2 through the support link 42, so that the support bar 41 can be retracted only by rotating the support link 42, and the column shrinks and compresses the two telescopic links 32 and can slide horizontally after being squeezed. The displacement paths of the two are different. After the support bar 41 cooperates with the vertical strip 44, the telescopic frame structure 3 can be restricted and locked, so as to maintain the overall stability of the fence.
