DETAILED DESCRIPTION

[0018] The utility model will be further explained in detail below in combination with the drawings and specific embodiments.

[0019] As Figures 1-2 shown, a zinc steel guardrail convenient to dismount, including one left and right two support columns 1, support column 1 between two are equipped with cross connecting rod 2, cross connecting rod 2 are uniformly connected with multiple guard bars 3, support column 1 are connected with the horizontal positioning plug post 4 through sleeve connecting piece, the four corners of the radial section of positioning plug post 4 are concentric and the radius is consistent arc, the both ends of cross connecting rod 2 and positioning plug post 4 are respectively corresponded and are inserted, and positioning plug post 4 is connected with cross connecting rod 2 through first bolt 5,

[0020] As Figures 1-2 shown, the length direction of cross connecting rod 2 is sequentially provided with multiple installation square holes 6, guard bar 3 is corresponded and passes through installation square hole 6, and is connected with cross connecting rod 2 through second bolt 7, and cross connecting rod 2 is equipped with multiple fixed hole sleeves 8, and the rear middle part of fixed hole sleeve 8 is provided with slot 9, and slot 9 and cross connecting rod 2 are slidably inserted, and the upper and lower ends of the rear side of fixed hole sleeve 8 are provided with corresponding installation round holes 10, and the diameter of installation round hole 10 is consistent with the diameter of installation square hole 6, and the front end of fixed hole sleeve 8 is provided with through hole 11, and through hole 11 corresponds with second bolt 7, when second bolt 7 passes through through hole 11 and is connected, installation round hole 10 and installation square hole 6 are coaxial and corresponded.

[0021] When assembling, after cross connecting rod 2 and positioning plug post 4 are inserted, first bolt 5 is connected, then multiple guard bars 3 and cross connecting rod 2 are connected using second bolt 7, which is very convenient to dismount and install. Of course, the biggest advantage of the present scheme is that it is widely applicable and flexible in structure, and can be adapted to the installation of square rods and round rods.

[0022] As Figure 1 shown, for the installation of square rods for cross connecting rod 2 and guard bar 3, the plane four sides of positioning plug post 4 can be inserted and limited with square cross connecting rod 2, as Figure 3 shown, after being connected by first bolt 5, it can ensure that cross connecting rod 2 is stable enough, and guard bar 3 is inserted into installation square hole 6 corresponding in diameter, and then connected by second bolt 7, which can ensure the stable installation of guard bar 3.

[0023] As Figure 2 shown, when the guard bar 3 of the round rod structure needs to be matched, according to the installation quantity and installation position, the corresponding fixed hole sleeve 8 is inserted on the cross connecting rod 2, the installation round hole 10 is coaxial with the installation square hole 6, and the guard bar 3 with the same diameter as the installation round hole 10 can be correspondingly penetrated, and then the cross connecting rod 2, the guard bar 3 and the fixed hole sleeve 8 are connected by the second bolt 7 passing through the through hole 11, so that the round rod structure guard bar 3 can be firmly installed.

[0024] The transverse connecting rod 2 can also adopt a circular rod structure, and the four sides of the positioning plug 4 are in arc-shaped structure to be stably plugged with the transverse connecting rod 2, as shown in Figure 4 It should be noted that the positioning hole sleeve 8 needs to be replaced by the arc-shaped structure of the plug slot 9 at this time, and since the positioning hole sleeve 8 is a small and portable accessory, it will not increase the cost and burden too much.

[0025] As shown in Figures 1-2 The sleeve connecting piece includes a support sleeve ring 12 which is vertically slidably sleeved outside the support column 1, and the positioning plug 4 is fixed outside the support sleeve ring 12, and the support sleeve ring 12 is connected with the support column 1 through the third bolt 13.

[0026] The support sleeve ring 12 and the support column 1 are detachably installed, which provides convenience for subsequent replacement of the transverse connecting rod 2, and only the support sleeve ring 12 needs to be removed, without the need to remove the support column 1 as a whole.

[0027] As shown in Figure 1 The bottom end of the support column 1 is fixed with a column base 14, and the column base 14 is provided with a grounding hole 15. By providing the grounding hole 15 on the column base 14, the support column 1 and the building can also be connected in a detachable manner, further expanding the use scenarios, such as being applied to various prefabricated buildings, facilitating the disassembly and assembly of various components.

[0028] The positioning hole sleeve 8 is made of a rubber material. When affected by thermal expansion and cold contraction, the rubber material can effectively play a buffering effect and effectively reduce the abnormal noise problem.
