Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, and more specifically, to a construction warning metal sign. Background Technology

[0002] Construction warning signs are placed at construction, maintenance, and road construction sites to remind, warn, or guide pedestrians and vehicles to pay attention to safety. Their main function is to ensure the safety of the construction area and prevent accidents.

[0003] Chinese Patent Publication No. CN219637751U discloses a warning sign for municipal construction. This design allows for easy replacement of warning signs by simply rotating the bottom end of the baffle away from the sign body. This exposes the sign on the outside of the baffle, preventing obstruction and interference. Construction workers can then easily install, remove, and replace the sign using a slot, providing appropriate warnings to pedestrians and vehicles. The replacement process is simple and convenient. By limiting the position of the baffle relative to the sign body, the stability of both the sign body and the baffle is ensured, maintaining parallelism. This municipal construction warning sign exhibits good stability.

[0004] The above solution requires removing the warning signs when they need to be replaced, and then having workers bring spare signs and tools (such as screwdrivers and wrenches) to the site to install new ones, which increases the workload and reduces the convenience of changing signs.

[0005] Therefore, a construction warning metal sign is proposed to address the above issues. Utility Model Content

[0007] This utility model provides a construction warning metal sign that can improve the problems existing in related technologies: when replacing and installing new warning signs, workers need to bring spare signs and tools (such as screwdrivers and wrenches) to the site, which increases the workload and reduces the convenience of replacing signs.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] This application provides a construction warning metal sign, including: a first bracket, a second bracket, and two warning signs. The outer ends of the first bracket and the second bracket are rotatably connected by hinges. The two warning signs are respectively set on the first bracket and the second bracket. Each warning sign includes rectangular strips distributed at equal intervals. Slogans are printed on all four sides of the outer side of each rectangular strip. The interior of each rectangular strip is hollow and has a rotating shaft. One end of the rotating shaft has an adjustment component. The adjustment component includes vertically distributed arc-shaped grooved wheels. The arc-shaped grooved wheels are fixedly connected to the rotating shaft. The rotation of the arc-shaped grooved wheels causes the rotating shaft to drive the rectangular strips to rotate. The equally distributed rectangular strips rotate simultaneously to switch display surfaces.

[0011] The technical solutions described in this application embodiment have at least the following technical effects:

[0012] The warning sign consists of multiple equally spaced rectangular strips, each with a slogan printed on its surface. Multiple adjustment components are installed on the sides of the sign, corresponding one-to-one with each rectangular strip and connected via a rotating shaft. Four drive slots on an arc-shaped grooved wheel engage with roller pins on an active dial, so that each rotation of the active dial causes the arc-shaped grooved wheel to rotate the rectangular strips 90 degrees. By rotating multiple rectangular strips simultaneously, the display surface can be switched. Therefore, changing the slogan only requires turning a knob, improving efficiency.

[0013] In some embodiments, a solar panel is installed on the top of the first bracket, and an LED light sign is provided between the first bracket and the second bracket. The LED light sign is connected to the solar panel via cables.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 - Figure 5 A construction warning metal sign includes: a support 1, a support 2, and two warning signs 6. The outer ends of the support 1 and the support 2 are rotatably connected by hinges 3. The two warning signs 6 are respectively set on the support 1 and the support 2. The warning sign 6 includes rectangular strips 64 distributed at equal intervals. Slogans are printed on all four sides of the rectangular strips 64. The rectangular strips 64 are hollow inside and have a rotating shaft 65 inside. One end of the rotating shaft 65 is provided with an adjustment component 7. The adjustment component 7 includes vertically distributed arc-shaped grooved wheels 71. The arc-shaped grooved wheels 71 are fixedly connected to the rotating shaft 65. The rotation of the arc-shaped grooved wheels 71 causes the rotating shaft 65 to drive the rectangular strips 64 to rotate. The equally distributed rectangular strips 64 rotate simultaneously to switch the display surface.

[0037] The device in this solution is mainly used to place on the road during municipal road construction to warn passing vehicles and pedestrians. The device in this solution is stackable. The bracket 1 and bracket 2 are rotatably connected by a hinge 3, so that it can be erected after being unfolded. The mounting frame 8 can be detachably installed on the outer end of both bracket 1 and bracket 2. It can be installed by bolts or clips. The mounting frame 8 is mainly used to install the warning sign 6. The warning sign 6 can rotate with bracket 1 or bracket 2 after being installed on the mounting frame 8.

[0038] The warning sign 6 is composed of multiple equally spaced rectangular strips 64. Each rectangular strip 64 is rectangular and has a slogan printed on it. Multiple adjustment components 7 are installed on the side of the warning sign 6. Each adjustment component 7 corresponds to one of the rectangular strips 64 and is connected by a rotating shaft 65. The four drive slots 72 on the arc-shaped grooved wheel 71 are adapted to the roller pins 76 on the active dial 73. When the active dial 73 rotates once, the arc-shaped grooved wheel 71 drives the rectangular strips 64 to rotate 90 degrees. By rotating multiple rectangular strips 64 at the same time, the display surface can be switched. Therefore, when changing the slogan, only the knob 9 needs to be turned, which improves the efficiency of changing the slogan.

[0039] Please see Figure 1 and Figure 2 A solar panel 4 is installed on the top of bracket 1, and an LED light sign 5 is installed between bracket 1 and bracket 2. The LED light sign 5 is connected to the solar panel 4 through a cable.

[0040] A solar panel 4 is rotatably installed on top of bracket 1. The solar panel 4 mainly generates electricity by receiving sunlight to power the LED light sign 5, enabling the LED light sign 5 to light up and display the information on it. The LED light sign 5 is located between bracket 1 and bracket 2, and the LED light sign 5 is connected to the solar panel 4 through a top-mounted cable. The cable also serves to suspend the LED light sign 5. It is worth mentioning that at night, the LED light sign 5 can be switched to battery power or directly connected to the power supply used during construction.

[0041] Please see Figure 3 and Figure 4 The warning sign 6 also includes a fixed frame 61. The outer ends of bracket 1 and bracket 2 are detachably mounted with mounting frames 8. The fixed frame 61 is fixedly connected to the mounting frame 8. The outer end of the fixed frame 61 is fixedly mounted with a mounting shell 62. The adjustment component 7 is located inside the mounting shell 62.

[0042] Two side plates 63 are fixedly installed inside the fixed frame 61. A rectangular bar 64 is located between the two side plates 63. One end of the rotating shaft 65 is rotatably connected to one of the side plates 63, and the other end of the rotating shaft 65 passes through the other side plate 63. A connecting block 66 is fixedly installed on the outer end of the rotating shaft 65. The rotating shaft 65 is fixedly installed inside the rectangular bar 64 through the connecting block 66.

[0043] The warning sign 6 in this solution is mainly used to display warning slogans. The warning sign 6 is made of stainless steel and primarily displays slogans through multiple equally spaced rectangular bars 64. Each rectangular bar 64 has the same gap between it to prevent them from jamming when rotating. The interior of each rectangular bar 64 is hollow to reduce weight and save costs. Slogans are printed on all four sides of each rectangular bar 64. Combining the slogans displayed on the same side of multiple rectangular bars 64 forms a complete slogan, meaning four slogans can be displayed. Since the warning sign 6 is installed on both bracket 1 and bracket 2, a total of eight slogans can be displayed. Because there are gaps between the rectangular bars 64, the printed slogans need to be as concise as possible, with enlarged fonts.

[0044] Multiple equidistant rectangular bars 64 are located inside the fixed frame 61, which is fixed to the mounting frame 8. Two side plates 63 are fixed inside the fixed frame 61, and the rectangular bars 64 are located between the two side plates 63. A rotating shaft 65 is located inside the hollow of the rectangular bars 64, and two connecting blocks 66 are fixed to the outer end of the rotating shaft 65. The connecting blocks 66 fix the rotating shaft 65 to the inside of the rectangular bars 64, and the rotating shaft 65 can drive the rectangular bars 64 to rotate. One end of the rotating shaft 65 is rotatably connected to the side plate 63, while the other end extends through another side plate 63 to the outside and connects to the adjusting component 7. The rotating shaft 65 can drive the rectangular bars 64 to rotate.

[0045] A mounting shell 62 is fixed to one side of the fixed frame 61. The interior of the mounting shell 62 is hollow, mainly to accommodate the adjustment component 7. One end of the rotating shaft 65 extends into the inside of the mounting shell 62.

[0046] Please see Figure 3 - Figure 5 The adjustment assembly 7 also includes an active dial 73, an extension rod 75 fixedly installed at the outer end of the active dial 73, a roller pin 76 fixedly installed at the outer end of the extension rod 75, and four drive slots 72 adapted to the roller pins 76 at the outer end of the arc-shaped grooved wheel 71. The active dial 73 pushes the arc-shaped grooved wheel 71 to rotate by inserting the roller pins 76 into the drive slots 72.

[0047] A locking arc block 74 is fixedly installed at the bottom of the active dial 73. The outer end of the arc-shaped grooved wheel 71 has four arc-shaped grooves 78 that are adapted to the locking arc block 74. When the rolling pin 76 disengages from the drive groove 72, the locking arc block 74 abuts against the arc-shaped grooves 78 to form a limit.

[0048] A connecting rod 10 is fixedly installed on the top of the active dial 73, and a knob 9 is fixedly installed on the top of the connecting rod 10. A connecting shaft 77 is fixedly installed on the bottom of the active dial 73, and the active dials 73, which are evenly distributed, are connected by the connecting shaft 77.

[0049] The adjustment component 7 in this design is mainly used to drive the rectangular bar 64 to rotate. The arc-shaped grooved wheel 71 is fixed to one end of the extension of the rotating shaft 65. The arc-shaped grooved wheel 71 is semi-circular, unlike traditional grooved wheels which are arc-shaped. Four drive grooves 72 are formed on the outer end of the arc-shaped grooved wheel 71, allowing it to rotate 90 degrees each time. An extension rod 75 is fixed to the outer end of the active dial 73. The extension rod 75 extends outwards, and a rolling pin 76 is fixed to the outer end of the extension rod 75. The rolling pin 76 interacts with the drive grooves... With 72 phases of adaptation, when the active dial 73 rotates, it will drive the roller pin 76. When the roller pin 76 is in contact with the drive groove 72, it will push the arc-shaped grooved wheel 71 to rotate. The rotating shaft 65 will drive the rectangular bar 64 to rotate. At this time, the arc-shaped grooved wheel 71 and the active dial 73 rotate simultaneously. When the roller pin 76 disengages from the drive groove 72, the arc-shaped grooved wheel 71 will stop rotating. By setting four drive grooves 72, the angle of rotation can be ninety degrees each time, so that the rectangular bar 64 can be flipped over.

[0050] A locking arc block 74 is fixed at the bottom of the active dial 73, and four arc grooves 78 are opened at the outer end of the arc groove wheel 71. The arc grooves 78 are adapted to the locking arc block 74. When the roller pin 76 is connected to the drive groove 72, the locking arc block 74 does not abut against the arc groove 78. When the roller pin 76 disengages from the drive groove 72, that is, when the arc groove wheel 71 stops rotating, the locking arc block 74 will abut against one of the arc grooves 78. At this time, the locking arc block 74 can rotate, while the arc groove wheel 71 is stuck and cannot rotate, which plays a limiting role and prevents the arc groove wheel 71 from driving the rectangular bar 64 to rotate on its own.

[0051] A connecting shaft 77 is fixed at the bottom of the active dial 73. The connecting shaft 77 is connected to the active dial 73 located below, which allows multiple adjustment components 7 to be connected together and driven synchronously. The connecting shaft 77 on the lowest adjustment component 7 is rotatably connected to the bottom of the mounting housing 62, while the active dial 73 located at the top is fixed with a connecting rod 10. The connecting rod 10 extends through the mounting housing 62 to the outside and is fixed with a knob 9. By rotating the knob 9, multiple adjustment components 7 can be rotated simultaneously to drive multiple rectangular bars 64. Compared with the traditional method of replacing warning signs, this device only requires rotating the knob 9, thereby improving the convenience of replacement.

[0052] Working principle: When the sign needs to be replaced, simply rotate knob 9 to make connecting rod 10 drive multiple active dials 73 to rotate simultaneously. When roller pin 76 engages with drive groove 72, it will push arc-shaped groove wheel 71 to rotate. Rotating shaft 65 will then drive rectangular bar 64 to rotate, allowing rectangular bar 64 to flip over. When arc-shaped groove wheel 71 stops rotating, locking arc block 74 will abut against one of the arc-shaped grooves 78, and arc-shaped groove wheel 71 will be stuck and unable to rotate, thus limiting its rotation and preventing arc-shaped groove wheel 71 from driving rectangular bar 64 to rotate on its own. By rotating knob 9, multiple adjustment components 7 can be rotated simultaneously to drive multiple rectangular bars 64. Compared with the traditional method of replacing warning signs, this method can improve the convenience of replacement.
