[0001] The utility model relates to the technical field of guardrail installation, in particular to a height-adjustable guardrail installation and fixing device. Background Technique

[0002] The earliest wooden fence appeared as an obstacle set up for penning various livestock. Developed to the present, fences often appear in different appearance forms in our lives, with very wide uses and connotations. The existing patent publication number CN204960500U discloses a quick-install guardrail, including a column and a crossbar. A sliding hole with its depth direction consistent with the length direction of the crossbar is arranged on the outer side surface of the column. A fixing member is slidably arranged on the inner side wall of the sliding hole. A fixing hole for inserting the end of the crossbar to fix the crossbar is arranged on the side surface of the fixing member facing the crossbar. A driving member for pushing the fixing member to move towards the crossbar direction is arranged between the fixing member and the bottom wall of the sliding hole. The key point of its technical solution is that the driving member pushes the fixing member towards the crossbar direction, and the end of the crossbar moves relative to the fixing hole and inserts into the fixing hole, realizing the fixation of one end of the crossbar. The other end of the crossbar is also fixed in the above way, realizing the fixation of the crossbar between adjacent columns. Since this structure does not require the use of a number of bolts for fixation, a large amount of time for screwing bolts can be saved, achieving the effect of improving the installation efficiency of the guardrail.
