Description

Technical Field

[0001] This utility model relates to the field of triangular sign device technology, specifically to a triangular sign with high stability. Background Technology

[0002] Traditional warning triangles mostly use a folding structure, which has the advantage of taking up little space. However, due to their light weight, they are easily affected by air pressure differences generated by vehicles on the road, causing them to be blown away from their designated position by crosswinds, resulting in unstable warning and posing a safety hazard. Furthermore, the lightweight design of the folding structure also makes them less resistant to interference, making it difficult to remain stable in complex environments. Therefore, there is an urgent need for a warning triangle device that is both easy to store and possesses sufficient weight and stability to resist external disturbances.

[0003] Chinese Patent Publication No. CN222014929U discloses a warning triangle, whose working principle is based on the linkage design of the housing and the warning sign. The housing has a storage slot at its upper end, and the warning sign is connected to the housing via a pivot. In use, it can be rotated to unfold from the storage slot to a vertical position; when stored, it is completely folded and hidden within the slot. The housing has a built-in counterweight structure that provides stable support for the warning sign through its own weight, resisting crosswinds or pressure differences caused by vehicle movement. The flipping mechanism consists of an elastic element and a sliding block: the elastic element pushes the sliding block along a guide rail, driving the connecting rod to automatically unfold the warning sign to a preset angle; a limiting structure physically blocks and fixes the position of the warning sign to prevent accidental folding. In the unfolded state, the reflective layer on the surface of the warning sign provides a warning function, while the rounded transition design at the bottom of the housing prevents tire damage when run over by vehicles. When stored, the warning sign is completely embedded in the storage slot, and the housing forms a closed unit, facilitating carrying and storage. However, the elastic element in this device only provides unidirectional elastic force, and the warning sign is prone to swaying in strong winds after it is unfolded, thus affecting the stability of the warning sign.

[0004] Therefore, this application aims to provide a highly stable triangular card to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned issues, a highly stable triangular warning sign is provided. This sign utilizes a hinged connection combined with a mechanical locking mechanism, incorporating a sliding base and a linkage mechanism within the housing. The movable base, via a return spring, pushes a rotating block towards the hinged end, causing the connecting rod to unfold the warning sign to a vertical position. Upon full unfolding, a spring-loaded ejector block within the sliding groove pops out and engages with a limiting groove, forming a rigid lock. This design retains the convenience of flexible unfolding while eliminating the risk of retraction through bidirectional fixation. This design can stably maintain the vertical posture of the warning sign even in strong winds or vibrations, solving the problem of unstable warning signs caused by traditional unidirectional elastic components that lead to swaying.

[0006] To address the problems of existing technologies, this utility model provides a highly stable triangular sign, comprising a shell and a triangular sign body. The triangular sign body is hinged to one end of the shell. A receiving groove is formed at the top of the shell, and a movable base is installed in the receiving groove. A first rotating block is slidably connected in the movable base, and a second rotating block is connected to the first rotating block via a connecting rod. The second rotating block is fixedly connected to the triangular sign body. A first return spring is provided in the movable base, and a limiting block is provided at the top of the movable base. A push-out groove is formed near the hinge on the limiting block. A sliding groove is formed at the top of the first rotating block, and a push-out block adapted to the push-out groove is slidably connected in the sliding groove. A second return spring is provided in the sliding groove. When released, the first return spring pushes the first rotating block to move towards the hinge, and the first rotating block pushes the second rotating block via the connecting rod. The second rotating block causes the triangular sign body to unfold. When the first rotating block moves along the limiting block to the push-out groove, the push-out block is pushed out by the second return spring, and the position of the first rotating block is fixed.

[0007] Preferably, a counterweight is installed inside the receiving groove.

[0008] Preferably, the receiving groove is provided with a plurality of threaded sleeves, and the counterweight is provided with through holes adapted to the threaded sleeves. When the counterweight is installed in the receiving groove, the threaded sleeves are inserted into the through holes of the counterweight, and at this time, bolts are threadedly connected to the threaded sleeves.

[0009] Preferably, a guide rod is provided horizontally inside the movable base, and a through hole adapted to the guide rod is opened at the bottom of the first rotating block. The guide rod is inserted into the through hole, and the first reset spring is sleeved on the guide rod.

[0010] Preferably, a first anti-detachment block is provided in the groove at the top of the first rotating block near the opening, and a second anti-detachment block is provided at the bottom of the ejector block.

[0011] Preferably, a locking mechanism is provided between the triangular sign body and the housing. The locking mechanism includes a locking sleeve that is fixedly connected to the triangular sign body. A fixing pin is slidably connected inside the locking sleeve. A locking plate is provided at one end of the housing. A fixing hole is provided on the locking plate. When the triangular sign body is stored in the receiving groove, the fixing pin is inserted into the fixing hole.

[0012] Preferably, a reflective sheet is fixedly adhered to one side of the triangular sign body.

[0013] Preferably, the edges of the triangular sign body and the shell are chamfered.

[0014] The advantages of this utility model compared to the prior art are: 1. This utility model forms a self-stabilizing structure through a double spring linkage and a mechanical locking mechanism, replacing the traditional unidirectional elastic component. After the first return spring drives the unfolding, the engagement between the ejector block and the ejector slot forms a rigid lock, effectively resisting strong wind forces, preventing the warning sign from swinging or accidentally folding, and significantly improving the stability and reliability of use.

[0015] 2. This utility model integrates a counterweight block within the housing's receiving groove and achieves rigid fixation via threaded bolts. The counterweight block enhances the inertia of the housing's bottom, and combined with the threaded connection's anti-displacement design, significantly reduces the risk of tipping over due to external vibrations or impacts, making the overall support more stable.

[0016] 3. This utility model incorporates a locking mechanism and safety details. The rigid constraint of the fixing pin and socket during storage prevents accidental unfolding, improving portability; the reflector enhances nighttime warning effects through reverse reflection, and the chamfered edges eliminate sharp corner hazards, balancing functionality and safety.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-6 As shown: A highly stable triangular sign includes a housing 1 and a triangular sign body 2. The triangular sign body 2 is hinged to one end of the housing 1. A receiving groove 3 is formed at the top of the housing 1. A movable base 4 is installed in the receiving groove 3. A first rotating block 5 is slidably connected in the movable base 4. The first rotating block 5 is connected to a second rotating block 6 through a connecting rod. The second rotating block 6 is fixedly connected to the triangular sign body 2. A first return spring 7 is provided in the movable base 4. A limiting block 8 is provided at the top of the movable base 4. The limiting block 8 has a top opening near the hinge. The first rotating block 5 has a sliding groove 10 at its top end. A push-out block 11 adapted to the push-out groove 9 is slidably connected in the sliding groove 10. A second return spring 12 is provided in the sliding groove 10. When released, the first return spring 7 pushes the first rotating block 5 to move towards the hinge. The first rotating block 5 pushes the second rotating block 6 through the connecting rod. The second rotating block 6 drives the triangular sign body 2 to unfold. When the first rotating block 5 moves along the limiting block 8 to the push-out groove 9, the push-out block 11 is pushed out by the second return spring 12, and the position of the first rotating block 5 is fixed.

[0026] In existing technologies, the elastic element only provides a unidirectional restoring force, causing the warning sign to sway easily in strong winds, affecting its stability. To solve this problem, in this application, the triangular sign body 2 is hinged to the housing 1, allowing the triangular sign body 2 to rotate around the hinge point. A movable base 4 is installed in the receiving groove 3 at the top of the housing 1. The first rotating block 5 inside the movable base 4 can slide within it and is connected to a second rotating block 6 fixed to the triangular sign body 2 via a connecting rod. When it is necessary to unfold the triangular sign body 2, the first return spring 7 inside the movable base 4 releases its elastic force, pushing the first rotating block 5 to move in the hinge direction. The first rotating block 5 transmits the thrust to the second rotating block 6 via the connecting rod, causing the second rotating block 6 to drive the triangular sign body 2 to unfold outward around the hinge point, completing the support action.

[0027] During the unfolding process, the first rotating block 5 slides along the limiting block 8. When it moves to the ejection groove 9 at the top of the limiting block 8, the ejection block 11, which is set in the sliding groove 10 at the top of the first rotating block 5, is pushed outward by the elastic force of the second return spring 12 and locks into the ejection groove 9. At this time, the engagement between the ejection block 11 and the ejection groove 9 forms a mechanical lock, preventing the first rotating block 5 from continuing to slide or retract. Through this linkage mechanism, the triangular sign body 2 can stably maintain its unfolded state after being fully unfolded, avoiding accidental folding due to external force or vibration, thereby achieving reliable stability.

[0028] Reference Figures 1-4As shown: A counterweight 13 is installed in the receiving groove 3.

[0029] When the triangular sign body 2 is unfolded, the shell 1, as a supporting foundation, needs to remain stable. The counterweight 13 enhances the inertia of the shell 1 in contact with the ground through its mass distribution, reducing the risk of swaying or tipping caused by external wind or vibration.

[0030] Reference Figure 3 As shown: The receiving groove 3 is provided with a plurality of threaded sleeves 14. The counterweight 13 is provided with through holes that are adapted to the threaded sleeves 14. When the counterweight 13 is installed in the receiving groove 3, the threaded sleeves 14 are inserted into the through holes of the counterweight 13. At this time, the threaded sleeves 14 are threaded with bolts.

[0031] When the counterweight 13 is placed in the receiving groove 3, its through hole aligns with the position of the threaded sleeve 14. At this time, the threaded sleeve 14 is embedded in the through hole to form a physical position. Then, the bolt is screwed in from the top of the threaded sleeve 14, and the pressure generated by the thread engagement presses the counterweight 13 tightly against the bottom of the receiving groove 3. This connection method not only forms a rigid constraint between the counterweight 13 and the housing 1, but also effectively resists displacement caused by external vibration or impact, ensuring that the counterweight 13 is always stably fixed in the preset position.

[0032] Reference Figure 5 and Figure 6 As shown: The movable base 4 is provided with a guide rod 15 in the horizontal direction. The bottom of the first rotating block 5 is provided with a through hole adapted to the guide rod 15. The guide rod 15 is inserted into the through hole. The first reset spring 7 is sleeved on the guide rod 15.

[0033] The first rotating block 5 is slidably connected to the guide rod 15 through the through hole, ensuring that its movement path is always along the extension direction of the guide rod 15, thereby accurately transmitting the spring's thrust to the first rotating block 5 and reducing frictional loss or jamming risk.

[0034] Reference Figure 6 As shown: A first anti-detachment block 16 is provided in the groove 10 at the top of the first rotating block 5 near the opening, and a second anti-detachment block 17 is provided at the bottom of the ejector block 11.

[0035] When the ejector block 11 slides outward within the slide groove 10 under the action of the second reset spring 12, the second anti-detachment block 17 contacts the first anti-detachment block 16 at the opening of the slide groove 10, preventing the ejector block 11 from completely detaching from the slide groove 10, and ensuring that the ejector block 11 always remains within the sliding range of the slide groove 10.

[0036] Reference Figure 1 and Figure 2As shown: A locking mechanism 18 is provided between the triangular sign body 2 and the housing 1. The locking mechanism 18 includes a locking sleeve 19 fixedly connected to the triangular sign body 2. A fixing pin 20 is slidably connected inside the locking sleeve 19. A locking plate 21 is provided at one end of the housing 1. A fixing hole 22 is provided on the locking plate 21. When the triangular sign body 2 is stored in the receiving groove 3, the fixing pin 20 is inserted into the fixing hole 22.

[0037] When the triangular sign body 2 is folded and inserted into the receiving slot 3, the locking sleeve 19 moves with the triangular sign body 2 to the locking plate 21 at one end of the housing 1. At this time, the fixing pin 20 slides inside the locking sleeve 19 and inserts into the fixing hole 22 on the locking plate 21. The fixing pin 20 and the fixing hole 22 form an interference fit, preventing the triangular sign body 2 from being accidentally unfolded due to external force or vibration in the stored state, ensuring that the device maintains a compact shape when carried or stored.

[0038] A reflective sheet is fixedly glued to one side of the triangular sign body 2.

[0039] The reflector fixedly attached to one side of the triangular sign body 2 achieves retroreflection of incident light through its special optical structure. When an external light source shines on the reflector surface, the microprism structure or reflective coating embedded inside reflects the light back to the direction of the light source along the original path, forming a high-brightness light spot, making the triangular sign highly visible at night or in low-light environments.

[0040] The edges of the triangular sign body 2 and the shell 1 are chamfered.

[0041] After the edges of the triangular sign body 2 and the shell 1 are chamfered, the resulting arc or bevel transition effectively eliminates sharp edges and reduces the risk of personnel scratches or equipment surface damage caused by accidental scratches or collisions during use.

[0042] Working Principle: The housing 1 serves as the supporting body, and the movable base 4 installed in the top receiving groove 3 constitutes the core transmission structure. When the warning sign is released, the first return spring 7 in the movable base 4 pushes the first rotating block 5 to slide along the guide rod 15 towards the hinge point. The connecting rod simultaneously drives the second rotating block 6, causing the warning sign body 2 to unfold around the hinge point. The ejector block 11 at the top of the first rotating block 5 is embedded into the ejector groove 9 of the limiting block 8 under the action of the second return spring 12, forming a mechanical lock to ensure a stable unfolded state. This linkage mechanism replaces the traditional one-way elastic element with double springs and physical buckles, effectively resisting strong wind forces and preventing the warning sign from swinging.

[0043] The counterweight 13 inside the receiving groove 3 enhances the stability of the bottom of the housing 1 through mass distribution. Its installation uses a threaded sleeve 14 and bolts, achieving both rapid positioning and preventing vibration displacement. The guide rod 15 passes through the through hole of the first rotating block 5, constraining the movement trajectory and serving as the support shaft for the first return spring 7, ensuring precise transmission of thrust. When the ejector block 11 slides, the first anti-detachment block 16 at the opening of the slide groove 10 contacts the second anti-detachment block 17 at the bottom of the ejector block 11, preventing the ejector block 11 from completely disengaging and ensuring the reliability of the locking mechanism 18.

[0044] In its stowed state, the triangular sign body 2 is inserted into the fixing hole 22 of the locking plate 21 of the housing 1 via the fixing pin 20 inside the locking sleeve 19, forming a rigid constraint. The reflector enhances the nighttime warning effect through retroreflection, while the chamfered edges eliminate the risk of sharp angles. When unfolded, each component automatically locks via spring linkage, and when stowed, it is fixed by physical pins. Combined with counterweight stability and guiding constraints, the overall structure maintains reliable stability in complex environments.
