Description

Technical Field

[0001] This utility model relates to the field of universal joint structures, specifically to a simple universal connection structure and guardrail. Background Technology

[0002] Currently, most guardrails on the market use rigid connections, which are fixed and suitable for straight roads. However, for roads with many curves, these rigid guardrails cannot be well adapted. To adapt them, guardrails with the corresponding curvature must be custom-made according to the curvature of the road surface, increasing production costs.

[0003] Currently available universal joints have complex structures and often include two connectors. If used directly on guardrails, they are inconvenient to assemble and the connecting parts of the connectors are exposed, which is not aesthetically pleasing.

[0004] Therefore, it is necessary to design a universal connection structure that can be applied to curved road guardrails. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a simple universal connection structure and guardrail.

[0034] Detailed Implementation

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] like Figure 1-4 As shown, this embodiment includes: a post 1 and a universal connector 2; the post 1 includes: a column body 11, a ball groove 12, and a first slot 13; the universal connector 2 includes: a tube body 21, a ball body 22, and a second slot 23. In this embodiment, the post 1 is used as the first connector, and the universal connector 2 is used as the second connector. The universal connector 2 can rotate directly on the post 1, which not only realizes the rotational connection between the post 1 and the guardrail, but also avoids the problem of the universal connector's connection structure being exposed and affecting aesthetics when using a traditional universal connector.

[0037] Symmetrically recessed hemispherical grooves 12 are provided on both sides of the column 11, and a first slot 13 is provided in the middle of the bottom of the groove 12. One end of the tube 21 is connected to a hemispherical sphere 22, and a second slot 23 is provided in the middle of the end of the sphere 22 facing away from the tube 21. The sphere 22 is rotatably installed in the groove 12 to realize the rotation of the universal connector 2 relative to the column 1. The shape and size of the sphere 22 are adapted to the groove 12. The end of the tube 21 facing away from the sphere 22 is a tubular structure for connecting the guardrail.

[0038] In one embodiment, a set of universal connectors 2 are provided on the left and right sides of the column 11 near the lower end. The universal connectors 2 are connected to one end of the guardrail, and the other end of the guardrail is connected to the universal connector 2 of another column 11.

[0039] In another embodiment, a set of universal connectors 2 is provided at the top and bottom of both sides of the column 11. The left and right sides of the column 11 can even have three, four, or more sets of guardrails as needed. Furthermore, the universal connectors 2 can be symmetrically distributed on both sides of the column 11, or asymmetrically distributed as required.

[0040] The bolt passes through the first slot 13 and the second slot 23 to connect the universal connector 2 to the column 1. One end of the bolt head is hidden inside the universal connector 2, while the other end passes through the second slot 23 and the first slot 13 before a nut is installed, which is also hidden inside the column 1. This design effectively conceals the bolt within the universal connector 2 and the column 1, preventing it from being exposed and affecting the aesthetics.

[0041] In another embodiment, the positions of the bolt and nut can be interchanged. The bolt head at one end of the bolt is hidden inside the column 1, and the other end passes through the first slot 13 and the second slot 23 before a nut is installed. The nut is hidden inside the universal connector 2.

[0042] In one embodiment, the diameter of the bolt head and nut is larger than the width of the second slot 23 and the first slot 13, thereby preventing the universal connector 2 from falling off the column 1. A gap is left between the bolt head and nut to allow the universal connector 2 to rotate relative to the column 1. The purpose of this design is to avoid the bolt and nut being locked too tightly, preventing the universal connector 2 from rotating freely relative to the column 1, but it is also not advisable to set the gap too large, preventing the universal connector 2 from rotating close to the column 1.

[0043] In one embodiment, the first slot 13 and the second slot 23 are rectangular holes or holes with an approximate rectangular shape.

[0044] Working principle:

[0045] A column 1 is vertically installed at intervals on the curved road. The columns 1 are connected to each other by railings. Since the railings are connected to the columns 1 by universal connectors 2, they can change their angle relative to the columns 1 without changing the shape of the columns 1 or railings to adapt to the curved road.

[0046] During the rotation of the universal connector 2 relative to the column 1, the ball 22 of the universal connector 2 rotates along the ball groove 12. Since the length direction of the first slot 13 is vertically set in this embodiment, the bolt can move along the first slot 13, and the universal connector 2 can rotate vertically relative to the column 1. At the same time, the bolt can also move along the length direction of the second slot 23, so that the universal connector 2 can rotate relative to the column 1 in the corresponding direction. For example, when the second slot 23 and the first slot 13 are in a cross shape, the universal connector 2 can rotate relative to the column 1 in a cross shape. When the second slot 23 is deflected at a certain angle relative to the first slot 13, the universal connector 2 can deflect at the corresponding angle and then rotate. Finally, the whole can adapt to rotation at multiple angles, thereby adapting to different curved roads.
