Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a metal guardrail with snap-on connection. Background Art

[0002] Guardrails are fences that are set up to avoid danger or block traffic. They can be seen everywhere in our lives. Guardrails are mainly used to protect personal safety and equipment facilities in residential areas, roads, commercial areas, public places, etc.

[0003] It is found in actual use that the existing guardrails have the following deficiencies during installation:

[0004] The upper and lower beams of the existing guardrails need to be connected to the support columns by welding or bolts. During installation, workers need to lift the beams, hold them at the joints of the holes, and then install the bolts to fix them. This makes the installation more laborious and requires additional workers to assist in the installation.

[0005] In addition, bolts need to be tightened at various locations during installation. In order to ensure the strength of the guardrail, the bolts need to be installed at many locations, which slows down the overall assembly of the guardrail.

[0006] Therefore, the present application provides a metal guardrail with a snap-on connection to meet the demand. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a metal guardrail with a snap-on connection.

[0008] The technical problem to be solved by the utility model is to provide a metal guardrail with a snap-fit ​​connection to solve the problems of the existing metal guardrail with a snap-fit ​​connection.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A metal guardrail with a snap-on connection comprises: a base, a column, a placement rack, a limit plate, a block, a supporting plate, a connecting block, a screw, a nut, a pressure block and a cross beam, wherein the upper end of the base is mounted with a column, the side of the column is mounted with a placement rack, the inner side of the placement rack is mounted with a limit plate, the placement rack is mounted with a block, the top of the block is mounted with a supporting plate, the side of the block is mounted with a connecting block, the bottom of the block is mounted with a screw, the screw is mounted with a nut, a pressure block is mounted on the upper end of the screw located at the nut, and the other end of the connecting block is mounted with a cross beam.

[0011] Preferably, the placement rack is in a "concave" shape, and a slot is provided in the middle of the placement rack, and the slot is in a rectangular shape.

[0012] Preferably, two groups of the limiting plates are provided, and the two groups of limiting plates are respectively located at the left and right ends of the inner opening of the placement rack in a mirror-symmetrical manner, and a rectangular groove is formed between the two groups of limiting plates.

[0013] Preferably, the support plate and the clamping block are in a "T" shape as a whole, and the support plate is horizontally mounted on the top of the placement rack.

[0014] Preferably, the connecting block is perpendicular to the clamping block, and the connecting block transversely penetrates the placement rack and extends outward from the middle of the two groups of limiting plates to the outer end of the placement rack.

[0015] Preferably, the block extends vertically to the inside of the placement rack, and the screw rod at the bottom of the block extends vertically downward to the outer lower end of the placement rack.

[0016] Preferably, the pressing block is disc-shaped, and the diameter of the pressing block is larger than the width of the slot of the placement rack.

[0017] Preferably, the pressing block is located between the nut and the placement rack, and the clamping block is fixed on the placement rack via a limiting plate and the pressing block.

[0018] When installing the crossbeam, the blocks on both sides of the crossbeam are inserted into the slots of the placement rack from top to bottom. The support plate on the top of the block can be horizontally mounted on the top of the placement rack. The connecting block passes through the two sets of limit plates of the placement rack to install the crossbeam between the two sets of columns to form a guardrail, so that the crossbeam is directly hung on the placement rack on the side of the column, so that no additional workers are required for auxiliary installation during installation, making the installation more convenient and labor-saving;

[0019] When the support plate is horizontally placed on the top of the placement frame so that the crossbeam is directly hung on the placement frame, the nut on the screw rod is adjusted from the outer lower end of the placement frame to make the pressure block close to the bottom of the slot of the placement frame. By tightening the nut, the pressure block can be fixed to the bottom of the slot of the placement frame, thereby limiting the bottom of the card block to prevent it from being pulled upward from the placement frame. The support plate on the top of the card block can be used to fix the upper and lower ends of the card block on the placement frame to complete the installation. Through this structural setting, the overall assembly of the guardrail is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
