[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a high-security anti-climbing steel mesh fence, comprising a plurality of annular tubes 1, which are arranged uniformly in a transverse direction, and the outside of the annular tubes 1 are each provided with a plurality of outer sleeves 2 which can rotate along the annular tubes 1, and the inside of the plurality of annular tubes 1 are provided with cross bars 3 one above and one below, and support bars 7 are installed between the cross bars 3, and a plurality of steel wire ropes 5 are vertically provided between the support rods 7, and the steel wire ropes 5 are combined to form a steel mesh.

[0024] In this embodiment, the cross bar 3 is located on both sides of the annular tube 1 and is equipped with limit rings 4. The width between the limit rings 4 matches the width of the outer sleeve 2. The outer sleeve 2 is arranged to pass through the channels between the limit rings 4.

[0025] The limiting ring can limit the annular tube so that the annular tube can be positioned, thereby avoiding lateral movement of the annular tube and affecting the protective effect.

[0026] In this embodiment, a plurality of insertion rods 6 are vertically installed on the bottom surface of the lower cross bar 3 , and the insertion rods 6 are arranged between the annular tubes 1 .

[0027] In this embodiment, both ends of the steel wire rope 5 are installed on the cross bar 3, the upper cross bar 3 is arranged close to the top of the inner cavity of the annular tube 1, and the lower cross bar 3 is arranged close to the bottom of the inner cavity of the annular tube 1.

[0028] In this embodiment, an annular guide portion 8 is formed on the inner wall surface of the openings at both ends of the outer sleeve 2. The inner diameter of the openings at both ends of the outer sleeve 2 is larger than the inner diameter of the middle of the outer sleeve 2. The guide portion allows the outer sleeve to pass smoothly through the bending part of the annular tube, avoiding getting stuck and affecting the rotation of the outer sleeve.

[0029] In this embodiment, the annular tube 1, the cross bar 3 and the support rod 7 are all made of metal materials, which increases the firmness and support effect.

[0030] In this embodiment, the outer ring surface of the outer sleeve 2 is wrapped with a rubber layer, which increases flexibility and avoids discomfort when held in the hand.

[0031] In this embodiment, the distance between the annular tubes 1 is smaller than the width of a human body, so that a human body cannot pass through between the annular tubes.

[0032] The device can be fixed on the ground by inserting a rod. Since the distance between the annular tubes 1 is smaller than the width of the human body, the human body cannot pass through the annular tubes to ensure the protective effect. A large number of outer sleeves are provided on the outer surface of the annular tubes. When the hand holds the annular tube, the hand can only contact the outer sleeve. When the hand exerts downward force, the outer sleeve can rotate along the annular tube, thereby losing the fixed point and being unable to climb up and exert force.

[0033] The steel net has only vertical steel wire ropes except for the horizontal steel wire ropes, which makes it impossible for criminals to grab hold of it. The horizontal steel wire ropes further prevent climbing and greatly increase safety.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
