Description

Technical Field

[0001] The utility model relates to a guardrail rotating joint component, belonging to the technical field of guardrails. Background Art

[0002] In actual application, guardrails usually need to have the function of rotating and opening. For example, there is a guardrail composed of a fixed part and a movable part. The fixed part is installed and fixed. The fixed part is generally a column. The lower end of the column is installed on the ground by bolts, and then two movable parts are hinged on the column. At this time, the column supports the movable part. The lower end of the column is connected and fixed to a chassis. The chassis is provided with a plurality of anchor holes, so that the bolts are passed through the anchor holes and installed on the ground to complete the fixation of the position of the column. The installation position of the guardrail is generally installed according to the set route, so the position of the column will be restricted. When the area on the ground where the anchor bolts are opened on the column is damaged due to reasons such as the hole being too large, the relative position of the anchor hole and the ground cannot be adjusted, that is, the anchor hole and the damaged area of ​​the ground cannot be staggered, which affects the smooth installation of the column. Therefore, it is necessary to design a guardrail rotating joint assembly that staggers the anchor hole from the damaged area of ​​the ground. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a guardrail rotating joint assembly to solve the problems raised in the above-mentioned background technology. The utility model enables the anchor holes to be staggered with the damaged area of ​​the ground.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a guardrail rotating joint assembly, including a column, the column is sleeved with two connecting parts that can rotate around the column, the bottom of the column is connected and fixed with a chassis, the annular side of the chassis is provided with two symmetrically arranged through holes, screws are inserted in the two through holes, two symmetrically arranged positioning plates are provided on the outside of the chassis, the two ends of the screw are respectively connected and fixed to the two positioning plates, the upper surface of the positioning plate is provided with anchor holes for inserting bolts, nuts are provided on both sides of the through holes along the length direction of the screw, and the nuts are threadedly connected to the screw.

[0005] The lockhole that is formed on the upper part of the body is formed on the upper part of the body, and the lockhole that is formed on the lower part of the body is formed on the bottom of the body, and the lockhole that is formed on the lower part of the body is formed on the bottom of the body.

[0006] Furthermore, a first threaded blind hole is opened in the middle position of the upper surface of the column, a threaded head is connected to the inner thread of the first threaded blind hole, an end of the threaded head located outside the first threaded blind hole is connected and fixed to an extension column, a second threaded blind hole is opened in the middle position of the upper surface of the extension column, the second threaded blind hole has the same specifications as the first threaded blind hole, and the outer diameter of the extension column is the same as the outer diameter of the column.

[0007] Furthermore, the threaded head and the extension column are an integrally formed structure, and the threaded head and the extension column are concentrically arranged.

[0008] Furthermore, the middle portion of the upper surface of the chassis is sunken downward to form a groove, and the lower end of the column is fixed in the groove.

[0009] Furthermore, a positioning hole is provided at the position where the positioning plate is provided with the screw, and the end of the screw is fixed in the positioning hole.

[0010] Beneficial effects of the utility model:

[0011] 1. Two sets of structures formed by upper and lower pipe sleeves are set on the column, and structures formed by limit rings and positioning sleeves are installed on the upper and lower sides of the structures formed by the upper and lower pipe sleeves. When the position of the structure formed by the upper and lower pipe sleeves on the column meets the requirements, the positioning screws are used to limit the relative position of the positioning sleeve and the column, so as to complete the convenient adjustment of the position of the structure formed by the upper and lower pipe sleeves.

[0012] 2. When the length of the column cannot meet the need for adjusting the spacing between the two sets of upper and lower pipe sleeves, select an appropriate number of extension columns so that the threaded head on one extension column is screwed into the second threaded blind hole on another extension column to realize the assembly of two adjacent extension columns. By analogy, the assembly of multiple extension columns is completed so that one threaded head in the structure formed by the multiple extension columns is screwed into the first threaded blind hole on the column to realize the assembly of the structure formed by the multiple extension columns and the column, thereby increasing the length of the column and meeting the need for adjusting the spacing between the two sets of upper and lower pipe sleeves.

[0013] 3. After the position of the chassis installed at the lower end of the column and the position of the ground are restricted, the relative position of the screw and the chassis is adjusted along the perforation, and then the relative position of the positioning plate and the chassis changes. At this time, the relative position of the anchor hole and the ground changes. After the anchor hole is offset from the damaged area of ​​the ground, the two nuts on a screw are used to limit the relative position of the screw and the chassis, and the relative position of the positioning plate and the chassis is adjusted, so that the anchor hole is offset from the damaged area of ​​the ground, which is convenient for smoothly limiting the position of the column without adjusting the position of the column.
