AI Technical Summary
When existing traffic signs are temporarily closed to traffic, the paint applied to them causes damage to the painted surfaces. After traffic resumes, the signs need to be repainted, which is inconvenient.
Design a simple variable traffic sign with a connecting mechanism including a limiting ring, a sign plate, and locking bolts. By combining the limiting ring and the sign plate, road markings can be quickly installed and removed, avoiding the need to spray conspicuous paint on the sign.
It provides protection for the painted surface of the sign, preventing damage, and is easy to install and remove, making it suitable for temporary road restrictions.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of traffic signs, specifically a simple and variable traffic sign. Background Technology
[0002] Traffic signs are generally made of aluminum alloy, with the painted markings facing the direction of vehicle travel, to indicate the location of each road to the driver.
[0003] In existing technologies, when roads are temporarily closed to traffic due to maintenance, engineering, or other reasons, conspicuous paint is usually sprayed onto the surface of the sign to indicate that the road ahead is closed. However, this method requires scraping after the road is reopened, which can easily damage the painted surface of the sign. Once damaged, the sign needs to be repainted, which is inconvenient. Utility Model Content
[0004] The purpose of this utility model is to provide a simple and variable traffic sign in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple variable traffic sign, including a sign, the back end of which is connected to a frame via a connector, a connecting mechanism installed on the sign, and a road marking sprayed onto the front end of the sign. The connecting mechanism includes a limiting ring integrally formed and protruding from the front end of the sign on both sides of the branch road of the road marking, and a through hole extending through to the back end of the sign is provided inside the limiting ring.
[0006] As a further embodiment of this utility model: the connecting mechanism further includes an identification plate sleeved on the outside of a set of limiting rings, the identification plate having a mating hole inside, the inner diameter of the mating hole being equal to the outer diameter of the limiting ring.
[0007] As a further embodiment of this utility model: the connecting mechanism further includes a locking bolt inserted into the inner wall of the round hole and the through hole, and the screw portion of the locking bolt is threaded with a locking nut.
[0008] As a further improvement of this utility model: a screw is inserted into the connector, and a connecting nut is screwed onto the outer wall of the screw.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. By setting up a connecting mechanism, the connecting mechanism can be easily installed and disassembled. After the road is reopened to traffic, it can be quickly disassembled without damaging the painted surface of the sign. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-3 In this embodiment of the utility model, a simple variable traffic sign includes a sign 1. The back end of the sign 1 is connected to the frame 8 via a connector 7. A connecting mechanism is installed on the sign 1. The front end of the sign 1 is sprayed with road markings 2.
[0017] In this embodiment: the traffic sign 1 is installed at the intersection, with the road marking surface 2 facing the direction of vehicle travel, making it easy for drivers to see. When the road ahead is under construction or maintenance, a connecting mechanism is installed at the corresponding position of the sign 1. The connecting mechanism is engraved with the reason why the road ahead is closed, indicating to the driver why the road ahead is closed. This method eliminates the need to spray eye-catching paint on the sign 1, making it more convenient to use.
[0018] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The connecting mechanism includes a limiting ring 3 integrally formed and protruding from the front end of the sign 1 and located on both sides of the branch road of the road marking 2. The limiting ring 3 has a through hole 4 extending through to the back end of the sign 1. The connecting mechanism also includes a sign plate 5 sleeved on the outside of a set of limiting rings 3. The sign plate 5 has a mating hole inside, and the inner diameter of the mating hole is equal to the outer diameter of the limiting ring 3. The connecting mechanism also includes a locking bolt 6 inserted into the inner wall of the round hole and the through hole 4. The screw part of the locking bolt 6 is threaded with a locking nut 9.
[0019] In this embodiment: when the road is closed to traffic due to engineering or maintenance, the sign plate 5 is inserted into the corresponding directional branch. After the sign plate 5 is aligned with the two limiting rings 3 of the corresponding group, the locking bolt 6 is passed through the round hole and the through hole 4. Then, the locking nut 9 is used to connect the threaded part of the locking bolt 6 until the locking nut 9 is fully locked. At this time, the end of the locking bolt 6 limits the sign plate 5, thereby deforming the sign 1. There is no need to spray eye-catching paint on the sign 1. After the road is reopened to traffic, the sign plate 5 can be disassembled.
[0020] It should be noted that signboard 5 has a striking color, making it easy for drivers to see.
[0021] Please refer to this carefully. Figure 1 A screw is inserted into connector 7, and a connecting nut is screwed onto the outer wall of the screw.
[0022] In this embodiment: the sign 1 is installed on the frame 8 by means of connector 7, screw and connecting nut.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
