DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1 - Figure 5 The utility model discloses a guardrail post fixing piece, comprising a base 1, a shaft sleeve 2 is fixedly connected to the top of the base 1, a slot 3 for inserting a column is reserved at the top of the shaft sleeve 2, at least three groups of through slots 4 connected to the slots 3 are formed in an annular array on the outer wall of the shaft sleeve 2, an extrusion block 5 is slidably connected in the through slot 4, and a fastening component 6 for pushing the extrusion block 5 to move is rotatably connected to the top of the shaft sleeve 2.

[0025] In this embodiment, when the guardrail is in use, the columns need to be fixed to the ground to complete the installation so that the guardrail has sufficient protective performance. The size of the columns of the guardrail varies depending on the type of use. Therefore, in order to fasten the columns to the ground, matching column fixings are required, which increases the installation cost of the guardrail.

[0026] Therefore, a sleeve 2 is arranged on the base 1, and a slot 3 for inserting the column is reserved on the top of the sleeve 2. At the same time, a through slot 4 connected to the slot 3 is opened on the outer wall of the sleeve 2, and an extrusion block 5 is slidably arranged in the through slot 4. Therefore, the size of the clampable column can be changed by rotating the fastening component 6 to adjust the distance between the extrusion blocks 5. The column fixing piece can be used for the installation of columns of various sizes, which can effectively expand the use scope of the column fixing piece, improve the practicality of the column fixing piece, and avoid the column fixing piece being specially matched with the guardrail column to increase the use cost of the guardrail.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the fastening assembly 6 includes a turntable 61 and a slide rail 62. The bottom of the turntable 61 is rotatably connected to the top of the sleeve 2. The middle of the turntable 61 is provided with an avoidance groove 7 for inserting a column. The bottom of the turntable 61 is located on the outer side of the sleeve 2 and is fixedly connected with a slide rail 62 for driving the extrusion block 5 to move.

[0028] In this embodiment, by providing a slide rail 62 at the bottom of the turntable 61, the turntable 61 can be rotated to push the slide rail 62 to rotate, and the slide rail 62 is used to drive the extrusion block 5 to be inserted into the slot 3, so as to apply pressure to the column in the slot 3, thereby clamping the guardrail column to achieve the fixation of the guardrail column, so that the column fixing part can fix the guardrail column by a simple rotation method, which can effectively reduce the difficulty of using the fastening component 6 and improve the installation efficiency of the guardrail.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the slide rail 62 extends with the curvature of an Archimedean spiral and is spirally arranged at the bottom of the turntable 61 , and a slide groove 8 connected to the slide rail 62 is opened on the top of the extrusion block 5 .

[0030] In this embodiment, since there are multiple extrusion blocks 5 and each extrusion block 5 is independent of each other, it is necessary to move the multiple extrusion blocks 5 simultaneously to synchronously press the outer wall of the guardrail column so that the slide rail 62 is Figure 5 As shown, the slide rail 62 is spirally arranged at the bottom of the turntable 61 with the curvature of an Archimedean spiral, and a slide groove 8 connected to the slide rail 62 is opened on the top of the extrusion block 5. When the turntable 61 rotates, the slide rail 62 will squeeze the side wall of the slide groove 8 during the rotation process, thereby pushing the extrusion block 5 to synchronously approach the column of the guardrail, so that multiple extrusion blocks 5 can synchronously clamp the column.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the bottom of the turntable 61 is provided with an annular groove 9 for sleeve-mounting the shaft sleeve 2, the inner wall of the annular groove 9 is protruded to form an annular portion 10 for preventing slipping, and the outer wall of the shaft sleeve 2 is provided with a limiting groove 11 for snapping into the annular portion 10.

[0032] In this embodiment, by opening an annular groove 9 at the bottom of the turntable 61, the turntable 61 can be installed on the top of the sleeve 2, so that the turntable 61 can be coaxially arranged with the sleeve 2, so that when the turntable 61 rotates, the slide rail 62 can keep synchronously pushing each extrusion block 5 to move.

[0033] By providing an annular portion 10 on the inner wall of the circular groove 9 and opening a limiting groove 11 connected to the annular portion 10 on the outer wall of the sleeve 2, the turntable 61 can be restricted by the annular portion 10 and the limiting groove 11 when connected to the sleeve 2, thereby preventing the turntable 61 from separating from the sleeve 2, making the connection between the turntable 61 and the sleeve 2 more stable and firm, and improving the quality of the column fixing parts.

[0034] In a further preferred embodiment of the present invention, Figure 3As shown, the inner side wall of the through slot 4 is provided with at least two stopper portions 12 formed by protrusions from top to bottom, and the outer side wall of the extrusion block 5 is provided with a track slot 13 slidably connected to the stopper portions 12 .

[0035] In this embodiment, since an assembly gap needs to be reserved during the production of the workpieces so that the workpieces can be spliced, a gap for installation will inevitably be generated between the extrusion block 5 and the through groove 4, causing the extrusion block 5 to tilt when sliding, which will not only increase the resistance to the movement of the extrusion block 5, but also affect the strength of the extrusion block 5 to clamp the column.

[0036] So observe Figure 3 It can be found that at least two limiting portions 12 are arranged on the inner wall of the through groove 4, and a track groove 13 is opened on the outer wall of the extrusion block 5, so that the extrusion block 5 is supported by the limiting portion 12 when sliding in the through groove 4. Multiple limiting portions 12 provide multi-point support, which makes the movement of the extrusion block 5 more stable and reduces the shaking amplitude, thereby reducing the resistance of the extrusion block 5 when moving, so that the column fixing piece can better clamp the column.

[0037] In a further preferred embodiment of the present invention, Figure 1 As shown, a plurality of mounting holes 14 are provided in a circular array on the top of the base 1 , and the mounting holes 14 are avoided from the extrusion block 5 .

[0038] In this embodiment, a plurality of mounting holes 14 are provided on the top of the base 1, so that the base 1 can be fixed with bolt fasteners, so that the sleeve 2 on the base 1 maintains a stable connection with the ground, so that the guardrail post will not shake when inserted into the slot 3 and tightened, which can effectively improve the stability of the guardrail after installation.

[0039] Since the outer peripheral side of the sleeve 2 is also provided with an extrusion block 5, which will interfere with the installation of the bolt fastener, the mounting hole 14 is avoided by the extrusion block 5 so that the column fixing piece will not be interfered when in use, which can effectively improve the practicality of the column fixing piece.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
