Abstract
Description
Technical Field
[0001] This utility model relates to the field of warning sign technology, specifically a portable high-speed construction warning sign. Background Technology
[0002] As the name suggests, a warning sign is a sign that serves to warn people. When highways are under construction, in order to prevent traffic accidents, a high-profile highway construction warning sign is usually set up at the entrance of the construction section to remind oncoming vehicles that the road ahead is under construction, effectively preventing safety accidents from occurring.
[0003] Conventional warning signs are fixedly installed on inclined supports, with auxiliary legs welded to the rear of the supports to prevent the signs from tipping over. However, during transport, the protruding auxiliary legs can scratch and collide with external objects, affecting transport efficiency. In addition, the warning signs are fixedly installed on the supports, and the signs cannot be replaced according to construction needs, resulting in limited use and a narrow scope of application.

[0029] 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.
[0030] Please see Figure 1-9 A portable high-speed construction warning sign includes a front support leg 1, with a rear support leg 2 hinged to the back of the front support leg 1. The length of the front support leg 1 is greater than the length of the rear support leg 2. The front support leg 1 and the rear support leg 2 are made of hollow stainless steel tubes, which not only have high strength but also reduce weight and make them easy to carry.
[0031] A lifting clip 4 is fixedly installed on the front of the front support leg 1. A sign plate 5 is installed on the lifting clip 4. A movable clip 6 is provided on the top of the sign plate 5. A connecting rod 7 is fixedly installed between two adjacent movable clips 6. A protrusion 8 is fixedly installed on the side of the movable clip 6. A strip hole 14 corresponding to the protrusion 8 is opened on the surface of the front support leg 1. The protrusion 8 is slidably installed in the inside of the strip hole 14.
[0032] A circular plate 9 is fixedly mounted on the side of the protrusion 8, and a vertical rod 10 is fixedly mounted on the top of the circular plate 9. A spring 11 and a retaining ring 12 are fitted on the outside of the vertical rod 10. The retaining ring 12 is embedded in the top of the front support leg 1, and the top of the vertical rod 10 passes through the retaining ring 12 and extends to the outside of the front support leg 1. A horizontal bar 13 is fixedly mounted on the top of the vertical rod 10. By pulling the horizontal bar 13 upward, the vertical rod 10 can slide upward in the retaining ring 12.
[0033] A locking mechanism 3 is hinged between the front outrigger 1 and the rear outrigger 2. There are two locking mechanisms 3 arranged symmetrically. The locking mechanism 3 includes two movable arms 31. The top of each movable arm 31 is movably installed inside the front outrigger 1 and the rear outrigger 2 respectively through a hinge pin 32. A locking bolt 33 is inserted and installed at the bottom of the movable arm 31. A locking nut 34 is threaded on the outside of the locking bolt 33. By loosening or tightening the locking nut 34, the loosening and tightening of the two movable arms 31 can be controlled.
[0034] A photovoltaic panel 15 is embedded on the surface of the front support leg 1 and below the signboard 5. When the warning sign is tilted, the photovoltaic panel 15 is exposed to sunlight. A back panel 16 is embedded on the surface of the rear support leg 2 to ensure that the space formed by the front and rear support legs is blocked when they are closed, thus improving the overall aesthetics. Three equally spaced rear panels 17 are embedded on the back of the front support leg 1 to cover and close the back of the front support leg 1, ensuring the overall aesthetics. An audible and visual alarm 18 is embedded on the surface of the middle rear panel 17, which can alert the passerby.
[0035] participate Figure 10 The photovoltaic panel 15 is electrically connected to the inverter, which is in turn electrically connected to the battery. The battery is connected to the audible and visual alarm 18 and the controller. The inverter, battery, and controller are all mounted on the rear panels 17 on both sides (not visible in the diagram due to viewing angle). The photovoltaic power generation technology used here is a mature existing technology and is directly used in this application. The current generated by the photovoltaic panel 15 is processed by the inverter and stored in the battery. Finally, the battery powers the controller and the audible and visual alarm 18, ensuring that the audible and visual alarm 18 can operate continuously.
[0036] Working principle: When in use, by loosening the locking nut 34 and locking bolt 33, the connection between the two movable arms 31 is loosened, and then the rear support leg 2 can be folded and retracted towards the front support leg 1, thus facilitating subsequent handling and carrying.
[0037] Conversely, tightening the locking nut 24 and locking bolt 33 secures the connection between the two movable arms 31, thereby stabilizing the rear support leg 2 and the front support leg 1 and ensuring that the rear support leg 2 and the front support leg 1 will not be easily folded and stored.
[0038] By pulling the horizontal bar 13 upward, the vertical bar 10 moves upward, the spring 11 is compressed, and then the movable clamp 6 moves upward along the strip hole 14. In this way, the movable clamp 6 no longer presses and fixes the sign plate 5, that is, the sign plate 5 is removed from the lifting clamp 4. The replacement of the sign plate 5 expands the entire warning sign area.
[0039] Conversely, when the new card plate 5 is inserted into the lifting clamp 4 and the pull on the crossbar 13 is released, the spring 11 pushes the round plate 9 down, and then the movable clamp 6 presses down on the card plate 5, thereby fixing the card plate 5.
[0040] After the front outrigger 1 and the rear outrigger 2 are opened, the warning sign can be placed. Sunlight will shine on the photovoltaic panel 15 to generate current, which will then be processed by the inverter and stored in the battery. The battery supplies power to the controller and the audible and visual alarm 18, ensuring that the audible and visual alarm 18 can run continuously to alert passing vehicles.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
