Description

The combination structure of straight and horizontal bars of guardrail

The present invention relates to a straight bar and horizontal bar combination structure of a guardrail, and in particular, to a guardrail straight bar and cross bar combination structure that is easy to assemble, has tight and stable combination, and has no combination gap.

According to reports, the guardrail is mainly fixed to the edge of the balcony upstairs to prevent people from falling from the balcony. Therefore, the stability of the guardrail deserves attention. It is known that the connection between the straight bar and the cross bar of the guardrail is usually after the straight bar passes through the cross bar, and then screws are passed through the straight bar and the cross bar laterally at the intersection of the two to secure the two. It is known that this kind of combination between the horizontal bar and the straight bar is fixed with screws. For the user, the assembly is quite labor-consuming and time-consuming. Moreover, the heads of the screws are exposed, which is also unsightly and lacks aesthetics.

Another method of assembling guardrails is an assembly method without screw parts, such as the CN202021218998. The upper crossbar (2) and the lower crossbar (3) of this conventional case are both provided with installation grooves (6) for accommodating the ends of the square tubes (5). The two inner walls of the grooves of the installation grooves (6) are Each square tube (5) is provided with a limit slider (12), and the end side wall of each square tube (5) is provided with a limiter chute (13) for matching the limit slider (12). Thereby, each square tube 5 can be embedded in the horizontal direction from one end of the upper crossbar (2) and the lower crossbar (3) in such a way that the limit chute (13) and the limit slide bar (12) are aligned, so that The square tubes (5) are evenly distributed between the upper crossbar (2) and the lower crossbar (3). After that, buckle bars (7) are arranged at equal intervals at the notches of the installation groove (6), and each square tube ( 5) Separate. Although the above-mentioned conventional solution has a clamping function and does not require screws, it has the following shortcomings in assembly, that is, each square tube (5) is limited by one end of the upper crossbar (2) and the lower crossbar (3). When the chute (13) is engaged with the limit slide (12), push the water in each square tube (5) After the horizontal displacement of the square tubes (5) is adjusted equidistantly, the distance between each two square tubes (5) is fixed with buckles (7). With such a structure, although there is no disadvantage of unsightly exposed screw parts, it still has the disadvantage of being labor-intensive and time-consuming to assemble.

In view of the above-mentioned deficiencies in the application of the conventional structure, the inventor made design improvements, and thus the present invention was produced.

Specifically, the main purpose of the present invention is to provide a straight bar and horizontal bar combination structure of a guardrail that is easy to assemble and has tight and stable coupling without any gap.

The main feature of the present invention is that the cross bar of the guardrail is provided with an insertion opening where the end of the straight bar is inserted, and a pair of insertion openings are provided inside the cross bar and on two corresponding sides on both sides of the insertion opening. The buckle plate has a buckle at its rear end, and the buckle is located within the caliber projection range of the embedding port; the two opposite outer walls of the end of the straight rod are provided with two buckles at positions corresponding to the two buckles. Horizontal slot. When the straight rod and the horizontal rod are inserted into the slot, the buckle is embedded in the slot. The end of the straight rod is inserted into the horizontal rod and then positioned so that there is no combination gap after the straight rod and the horizontal rod are combined. It is produced and has a stable combination; the inside of the cross bar is adjacent to the buckle and located on the inner wall away from the end of the embedding port. inside, and the distance between the baffle and the buckle is equivalent to the distance from the end of the straight bar to the slot. The baffle provides support and positioning for the end of the straight bar after the straight bar and the cross bar are inserted. With the above arrangement, the combination of the straight rods and the horizontal rods of the guardrail is easy to assemble and the combination is tight and stable without any gap.
