Description

Technical Field

[0001] This application relates to the field of warning flags, and in particular to a throwable warning device for road maintenance. Background Technology

[0002] Increased traffic volume has led to a gradual increase in six-lane and eight-lane highways, causing significant inconvenience for highway closures and maintenance. Furthermore, highway maintenance is typically a piecemeal process, often involving only isolated incidents and not requiring closures, which poses a considerable safety risk.

[0003] In current highway maintenance, it is usually necessary to install warning devices in advance to alert passing vehicles. The current main warning device is a traffic cone with reflective strips on its surface. These cones are typically made of plastic, which is easily damaged when run over by vehicles, thus reducing their warning effectiveness. Therefore, improvements are needed. Utility Model Content

[0004] To address the aforementioned issues, this application provides a throwable warning device for road maintenance.

[0005] This application provides a throwable warning device for road maintenance, which adopts the following technical solution:

[0006] A throwable warning device for road maintenance includes a support and a base. The support is mounted on the base, and the outer diameter of the support gradually tapers away from the base. The base has an arc surface on the side away from the support. A cavity is formed in the base, and a counterweight medium is stored in the cavity. A warning component is mounted on the support.

[0007] By adopting the above technical solution, when the warning flag is tilted by external force, the outer diameter of the support is gradually reduced in the direction away from the base, the base has an arc surface, and there is a counterweight medium in the base. When the warning flag is tilted as a whole, the shift of the center of gravity will generate a resisting torque, so that the warning device can quickly restore balance, reduce the possibility of damage to the warning device, and provide convenience for the warning device to more stably warn vehicles and construction personnel.

[0008] Preferably, the warning assembly includes a support rod and a warning flag, the support rod being mounted on a support, and the warning flag being mounted at the end of the support rod away from the support.

[0009] By adopting the above technical solution, the support rod and the warning flag work together to facilitate a more stable warning effect for vehicles and construction workers.

[0010] Preferably, the support is provided with a connecting groove, and the end of the support rod away from the warning flag is provided with two opposing insert plates. Each of the two opposing insert plates is provided with a positioning protrusion that cooperates with the support rod. After the two opposing insert plates are combined, a positioning groove for placing the support rod is formed between the two positioning protrusions. Both opposing insert plates are set in the connecting groove.

[0011] By adopting the above technical solution, when the warning device is needed, the worker connects the two insert plates to the support rod, so that both positioning protrusions abut against the support rod. At this time, the positioning groove between the two positioning protrusions facilitates the determination of the position between the insert plates and the support rod. The worker then inserts the assembled insert plates into the connecting groove to complete the installation of the warning device, thus providing convenience for the installation of the warning device.

[0012] Preferably, the support has a fixing hole that communicates with the connecting groove, a fixing post is provided in the fixing hole, the fixing post passes through two insert plates, a fixing ring is provided in the fixing hole, and the fixing ring is threadedly connected to the fixing post.

[0013] By adopting the above technical solution, when it is necessary to fix the support rod, the worker inserts the fixing post into the fixing hole, allowing the fixing post to pass through the two insert plates, and then installs the fixing ring on the fixing post to limit the fixing post, thus fixing the support rod and the two insert plates. At this time, under the limiting effect of the fixing post, the possibility of the support rod separating from the support is reduced, thereby further facilitating the stable provision of warning function by the warning component.

[0014] Preferably, the support rod is provided with a sealing ring, which abuts against the support.

[0015] By adopting the above technical solution, the sealing ring seals the connecting groove, reducing the possibility of external impurities or rainwater entering the connecting groove, making it less likely for external impurities to affect the installation of the support rod.

[0016] Preferably, the support rod is provided with a snap-fit ​​ring, the sealing ring is provided with an annular groove, and the snap-fit ​​ring is disposed in the annular groove.

[0017] By adopting the above technical solution, when a sealing ring is needed, the worker aligns the annular groove on the sealing ring with the snap-fit ​​ring, and then moves the sealing ring so that the snap-fit ​​ring snaps into the annular groove. At this time, the snap-fit ​​ring and the annular groove cooperate to limit the sealing ring, reducing the possibility of the sealing ring separating from the support rod, so that the sealing ring can more stably seal the connecting groove.

[0018] Preferably, the fixing hole is provided with a first sealing block and a second sealing block, the first sealing block abutting against the fixing post, and the second sealing block abutting against the end of the fixing ring away from the fixing post.

[0019] By adopting the above technical solution, the first sealing block and the second sealing block cooperate to prevent external impurities or rainwater from entering the fixing hole. On the one hand, this reduces the possibility of impurities affecting the installation of the fixing column, and on the other hand, it reduces the possibility of external impurities or rainwater damaging the fixing column.

[0020] Preferably, the base has a connecting ring on the side near the support, and the support has a fixing groove on the side near the base, with the connecting ring threadedly connected to the inner wall of the fixing groove.

[0021] By adopting the above technical solution, the worker puts the counterweight medium into the base, then aligns the connecting ring with the fixed groove, and rotates the base so that the connecting ring is threadedly connected to the inner wall of the fixed groove, thus completing the connection between the base and the support, which provides convenience for the worker to put in the counterweight medium.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting a base with a gradually decreasing outer diameter away from the base and a base with a rounded surface, the center of gravity of the warning device will shift when it is subjected to external impact, generating a resisting torque. This allows the warning device to quickly regain its balance, so that the warning component can provide a more stable warning effect for vehicles and construction workers.

[0024] 2. By setting fixed posts and fixed rings, the support rod and two insert plates are provided with limits, which improves the connection stability between the warning components and the support, so that the warning device can provide a more stable warning effect for vehicles and construction personnel;

[0025] 3. By setting a sealing ring, it is difficult for external impurities or rainwater to enter the connection groove, reducing the possibility of impurities or rainwater damaging the plug plate and clogging the connection groove, thus providing convenience for workers to install the warning components.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example 1:

[0034] Embodiment 1 of this application discloses a throwable warning device for road maintenance. (See also...) Figure 1 A throwable warning device for road maintenance includes a support 1 and a base 2. The support 1 is mounted on the base 2, and its outer diameter tapers away from the base 2. The base 2 has an arc-shaped surface 21 on its side away from the support 1. A cavity 22 is formed in the base 2, containing a counterweight medium. A warning component 3 is mounted on the support 1. Because the outer diameter of the support 1 tapers away from the base 2, and the base 2 has the arc-shaped surface 21, the center of gravity of the warning device shifts towards the ground. When the warning device is subjected to external force, this shift in the center of gravity generates a resisting torque, allowing the warning device to quickly regain balance and reducing the possibility of damage.

[0035] Reference Figure 1 The warning component 3 includes a support rod 31 and a warning flag 32. The support rod 31 is detachably connected to the side of the support 1 away from the base 2, and the warning flag 32 is fixed to the side of the support rod 31 away from the support 1. In this embodiment, the support rod 31 is made of spring steel wire, the support 1 and the base 2 are both made of rubber, and the counterweight medium is steel shot.

[0036] Reference Figure 1 and Figure 2 To facilitate the installation of the warning component 3, two opposing insert plates 4 are fixed at one end of the support rod 31 near the base 2. A connecting groove 11 is provided on the support 1, and both insert plates 4 are set in the connecting groove 11.

[0037] Furthermore, both insert plates 4 are provided with positioning protrusions 41 that cooperate with the support rod 31. After the two insert plates 4 are combined, a positioning groove 42 is formed between the two positioning protrusions 41 for the support rod 31 to be placed. At this time, the positioning groove 42 can determine the position of the support rod 31, thereby improving the positional accuracy between the insert plate 4 and the support rod 31.

[0038] Reference Figure 1 The support 1 has a fixing hole 12 that communicates with the connecting groove 11, and a fixing post 121 is provided in the fixing hole 12. The fixing post 121 passes through two insert plates 4, and a fixing ring 122 is provided in the fixing hole 12. The fixing ring 122 is threadedly connected to the fixing post 121.

[0039] When the warning component 3 needs to be installed, the worker fixes the two insert plates 4 onto the support rod 31, and then inserts the combined two insert plates 4 into the connecting groove 11. The worker then inserts the fixing post 121 into the fixing hole 12, so that the fixing post 121 passes through the two insert plates 4, and then installs the fixing ring 122 onto the fixing post 121 to complete the fixing of the fixing post 121. At the same time, under the action of the fixing post 121 and the fixing ring 122, the two insert plates 4 are limited, that is, the support rod 31 is limited, reducing the possibility of the support rod 31 separating from the support 1, thereby improving the connection stability between the warning component 3 and the support 1, so that the warning component 3 can provide a more stable warning effect for vehicles and construction personnel.

[0040] Reference Figure 1 Since the outer diameter of the support 1 is gradually tapered away from the base 2, the possibility of rainwater accumulating on the support 1 is reduced in rainy weather, further reducing the possibility of rainwater damaging the fixing column 121.

[0041] Reference Figure 1 The base 2 has an injection hole 23 that communicates with the cavity 22. The injection hole 23 is equipped with a sealing plug 231. The injection hole 23 facilitates the worker to deliver the counterweight medium into the cavity 22. The sealing plug 231 seals the injection hole 23, making it difficult for external impurities or rainwater to enter the cavity 22. The sealing plug 231 is made of silicone.

[0042] The implementation principle of Embodiment 1 of this application is as follows: When the warning device is subjected to external force, since the outer diameter of the support 1 is gradually reduced in the direction away from the base 2, and the base 2 has an arc surface 21, the warning device generates a resisting torque when tilted, which facilitates the warning component 3 to restore balance more quickly, and at the same time reduces the possibility of damage to the warning device.

[0043] Example 2:

[0044] Reference Figure 3 and Figure 4The difference from Embodiment 1 of this application is that a sealing ring 5 is provided on the support rod 31, and the sealing ring 5 abuts against the support 1.

[0045] To improve the sealing performance of the sealing ring 5, a snap ring 311 is fixed on the support rod 31, and an annular groove 51 is provided on the sealing ring 5, with the snap ring 311 disposed in the annular groove 51.

[0046] When the sealing ring 5 is needed, the worker aligns the annular groove 51 with the snap-fit ​​ring 311, causing the snap-fit ​​ring 311 to snap into the annular groove 51, thus completing the installation of the sealing ring 5. After the worker inserts the insert plate 4 into the connecting groove 11, the sealing ring 5 abuts against the support 1. At this time, the sealing ring 5 shields the connecting groove 11, reducing the possibility of external impurities or rainwater entering the connecting groove 11, making the connecting groove 11 less prone to blockage, and also reducing the possibility of damage to the fixing post 121 and the insert plate 4.

[0047] Reference Figure 3 A first sealing block 6 and a second sealing block 7 are provided in the fixing hole 12. The first sealing block 6 abuts against the fixing post 121, and the second sealing block 7 abuts against the side of the fixing ring 122 opposite to the fixing post 121. Both the first sealing block 6 and the second sealing block 7 abut against the inner wall of the fixing hole 12. The sealing ring 5, the first sealing block 6, and the second sealing block 7 are all made of silicone. The first sealing block 6 and the second sealing block 7 shield the fixing hole 12, reducing the possibility of rainwater or impurities entering the fixing hole 12, and further reducing the possibility of damage to the fixing post 121.

[0048] Reference Figure 3 and Figure 5 To facilitate control of the amount of counterweight medium, a connecting ring 24 is fixed to the side of the base 2 near the support 1, and a fixing groove 13 is provided on the side of the support 1 near the base 2. The connecting ring 24 is threadedly connected to the inner wall of the fixing groove 13. The base 2 also has an opening that communicates with the cavity 22. Workers place the counterweight medium into the cavity 22 through the opening. Because the base 2 and support 1 are separate units, workers can more accurately control the amount of counterweight medium added, ensuring the counterweight medium stably secures the warning device.

[0049] The implementation principle of Embodiment 2 of this application is as follows: During the use of the warning device, the sealing ring 5, the first sealing block 6 and the second sealing block 7 cooperate to reduce the entry of external impurities or rainwater into the fixing hole 12 and the connecting groove 11, making it less likely for the fixing hole 12 and the connecting groove 11 to become blocked, which facilitates the installation of the warning component 3, so that the warning device can provide a more stable warning effect for vehicles and construction personnel in the future.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
