Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a safety guardrail. Background Technology

[0002] During construction, in order to prevent safety accidents, safety fences are usually used to surround the construction site and warn unauthorized personnel and vehicles, thereby preventing them from entering the construction site.

[0003] The publication (announcement) number CN221277434U discloses a safety railing that uses more components, making installation and operation more convenient and stable. It includes a fixed base, a vertical rod, a first collar, a threaded groove, a threaded sleeve, a threaded rod, a handle, a second collar, a railing, a fixing sleeve, and bolts. The top center of the fixed base is connected to the bottom end of the vertical rod. The inner side of the first collar is adapted to the outer side of the vertical rod. The rear center of the first collar is connected to the inner end of the threaded sleeve. The inner wall of the threaded sleeve is screwed movably connected to the outer wall of the threaded rod. The outer side of the threaded rod is connected to the inner center of the handle. The inner side of the second collar is adapted to the outer side of the vertical rod. The right end of the second collar is connected to the lower left side of the railing. The middle right end of the railing is connected to the left side of the fixing sleeve. Bolts are movably installed inside the fixing sleeve.

[0004] While the above solutions are convenient to assemble, they are inconvenient to assemble between identical guardrails, and the fixed length of the guardrails makes them less applicable. Therefore, we propose a new type of safety guardrail. Utility Model Content

[0005] The main purpose of this utility model is to provide a safety railing that solves the problems of inconvenient assembly between identical railings and the limited applicability of railings with fixed lengths by setting up assembly units and blocking units.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a safety guardrail, including two posts, and further including: an assembly unit and a blocking unit disposed between the two posts;

[0007] The assembly unit includes a plug, a connecting column, a support spring, a connecting block, and a limiting frame plate. Each of the two opposite sides of the column has a placement groove, and the bottom wall of the placement groove has an installation hole. The plug is movably placed in the installation hole. The connecting column is fixedly set at the top of the plug and located in the placement groove. The support spring is fixedly set at the top of the placement groove. The connecting block is fixedly set at the bottom of the support spring and extends to the outside of the placement groove. The limiting frame plate is fixedly set at the bottom of the connecting block and surrounds the outer wall of the column.

[0008] The blocking unit includes a blocking crossbar, a blocking frame plate, a positioning vertical bar, and a baffle plate. The blocking crossbar is fixedly installed on the side of the connecting column. The blocking frame plate is movably sleeved on the outside of the blocking crossbar. A set of first through holes are opened on the upper and lower surfaces of the blocking frame plate at equal intervals. A second through hole is opened on the top surface of one end of the blocking crossbar. The positioning vertical bar moves through the blocking crossbar and the blocking frame plate sequentially through the first and second through holes. The baffle plate is fixedly installed at the top of the positioning vertical bar.

[0009] Preferably, the support spring and the connecting block are arranged in a one-to-one correspondence with the placement groove.

[0010] Preferably, every two of the barrier crossbars form a group and are symmetrically distributed on the side of the connecting post.

[0011] Preferably, the support spring and the mounting hole are located on the same vertical central axis.

[0012] Preferably, the positioning vertical rod and the connecting column are arranged parallel to each other.

[0013] Preferably, an anti-slip base is fixedly provided at the bottom of the column.

[0014] Preferably, the barrier frame has two symmetrical weight-reduction notches on its side.

[0015] Compared with the prior art, the safety railing of this utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting an assembly unit, the connecting block is pushed up by the limiting frame plate surrounding the outer wall of the column. After the limiting frame plate pushes the connecting block to squeeze the support spring at the top of the placement groove, the connecting column, which serves as the carrier of the blocking unit, is unobstructed and can be placed into the placement grooves on both sides of the column. The insert at the bottom of the connecting column can be inserted into the mounting hole on the bottom wall of the placement groove. The connecting column completes the initial bottom limit. After the limiting frame plate is released, the support spring deforms and restores, causing the limiting frame plate to reset and move down to the outside of the top of the connecting column. The connecting column completes the top limit. Blocking units can be assembled on both sides of the column. The assembly operation between the same guardrails in this solution is simple and flexible.

[0017] 2. In this utility model, by setting up a barrier unit, after the barrier frame plate is movably sleeved on the outside of the barrier crossbar, the barrier crossbar on the side of the connecting post can be adjusted to change its exposed area by translating on the barrier frame plate. After the connecting post is adjusted, the positioning vertical rod can be connected in series with the barrier frame plate and the barrier crossbar through the first through hole at the corresponding position on the upper and lower surfaces of the barrier frame plate and the second through hole on the top surface of one end of the barrier crossbar. The baffle plate fixedly set at the top of the positioning vertical rod prevents the positioning vertical rod from falling off. The overall length adjustment and fixing of the guardrail in this solution is simple and flexible. Attached Figure Description

[0041] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, a safety railing includes two posts 1, and also includes an assembly unit 2 and a blocking unit 3 disposed between the two posts 1;

[0042] Assembly unit 2 includes a plug 201, a connecting column 202, a support spring 203, a connecting block 204, and a limiting frame plate 205. The column 1 has a placement groove on each of its two opposite sides. The bottom wall of the placement groove has an installation hole. The plug 201 is movably placed in the installation hole.

[0048] The blocking unit 3 makes it easy and flexible to adjust and fix the overall length of the guardrail in this scheme.

[0049] The working principle of this utility model is as follows:

[0050] By pushing up the limiting frame plate 205 surrounding the outer wall of the column 1, the connecting block 204 is driven by the limiting frame plate 205 to press the support spring 203 at the top of the placement groove. The connecting column 202, acting as the carrier of the blocking unit 3, is then placed freely into the placement grooves on both sides of the column 1 without obstruction. The insertion post 201 at the bottom of the connecting column 202 is inserted into the mounting hole on the bottom wall of the placement groove. The connecting column 202 completes its initial bottom limiting. After releasing the limiting frame plate 205, the support spring 203 deforms and recovers, causing the limiting frame plate 205 to reset and move downwards to the outer side of the top of the connecting column 202. The connecting column 202 then completes its initial bottom limiting. The top limit is set, and the column 1 is equipped with the blocking unit 3 on both sides. After the blocking frame plate 302 is movably sleeved on the outside of the blocking crossbar 301, the blocking crossbar 301 on the side of the connecting column 202 is adjusted to adjust the exposed area on the blocking frame plate 302. After the connecting column 202 is adjusted, the positioning vertical rod 303 connects the blocking frame plate 302 and the blocking crossbar 301 in series through the first through hole at the corresponding position on the upper and lower surfaces of the blocking frame plate 302 and the second through hole on the top surface of one end of the blocking crossbar 301. The baffle 304 fixedly set at the top of the positioning vertical rod 303 prevents the positioning vertical rod 303 from falling.
