Description

Technical Field

[0001] This utility model relates to the field of construction inspection technology, and in particular to a warning sign for on-site inspection of highway bridges with a folding function. Background Technology

[0002] Warning signs for on-site inspection of highway bridges are core facilities for ensuring the safety of inspection operations. They are mainly used to delineate work areas and warn passing vehicles to give way. These devices are usually made of highly reflective materials to ensure good visibility at night or in low visibility conditions. Their structure needs to withstand the impact of severe weather such as strong winds and heavy rain, while also meeting the needs of frequent handling and rapid deployment in on-site operations. In special scenarios such as bridge inspection that require temporary closure of lanes, the stability and portability of warning signs are directly related to construction efficiency and personnel safety.

[0003] Traditional warning signs generally adopt a one-piece rigid structure, which is bulky and non-foldable. During transportation, they require a lot of loading space on the vehicle. When moving to another site, they often need special transport vehicles or multiple round trips for handling. This structural defect leads to low on-site deployment efficiency and increases manpower and time costs. At the same time, the corners of the rigid structure are easily bumped and damaged during handling. Repeated disassembly and assembly can also cause the connecting parts to loosen, affecting the safety of use and the life of the device. Utility Model Content

[0004] The purpose of this invention is to provide a foldable warning sign for on-site inspection of highway bridges, which solves the problem of traditional warning signs being bulky and inconvenient to transport.

[0005] To achieve the above objectives, this utility model provides a foldable warning sign for on-site inspection of highway bridges, comprising a first warning sign, a second warning sign rotatably mounted on the right end of the first warning sign, slots at the upper ends of the first and second warning signs, a connector fixedly mounted on the upper end of the first warning sign, a screw hole at the right end of the connector, a support rod fixedly mounted on the right end of the first warning sign, a screw fixedly mounted on the left end of the support rod, and a base fixedly mounted on the right end of the support rod. The support rod is connected to the base via a connecting seat. A folding assembly is provided between the first and second warning signs. The first warning sign serves as the main bearing surface of the device and is used for printing reflective warning markings. The second warning sign rotatably mounted on its right end expands the visibility range. The slots provide space for the connecting components to move and avoid interference. The connector enables quick docking of the support rod and the warning sign. The screw hole ensures a stable connection through threaded engagement. The support rod serves as the main load-bearing structure to maintain the upright state of the device. The screw and screw hole form a detachable connection. The base provides stability to the ground contact surface. The connecting seat optimizes the force transmission efficiency between the support rod and the base.

[0006] The folding assembly includes a fixing plate, which is fixedly installed between the first warning sign and the second warning sign. The first warning sign and the second warning sign are connected by a hinge. The fixing plate serves as the core skeleton of the folding assembly, maintaining the structural integrity of the two warning signs. The hinge enables the rotational freedom between the warning signs.

[0007] The fixed plate has a bottom ring fixedly installed at its upper end, and a release button is movably installed at the upper end of the bottom ring. The bottom ring serves as the locking base of the cone buckle mechanism, and the release button triggers the unlocking mechanism by pressing it.

[0008] The first warning sign has a connecting rod fixedly installed at its upper end, a first cone buckle movably installed at the upper end of the connecting rod, and a second cone buckle movably installed at the upper end of the connecting rod. The connecting rod provides an installation base for the cone buckle system, and the first cone buckle and the second cone buckle constitute a two-way locking component.

[0009] A first spring is fixedly provided between the first cone buckle and the second cone buckle. A limit end is fixedly provided at the lower end of the first cone buckle and the second cone buckle. The first spring enables the cone buckle to automatically reset, and the limit end controls the travel range of the cone buckle.

[0010] The release button has a convex ring fixedly installed at its lower end, and a second spring is fixedly installed between the release button and the fixing plate. The convex ring transmits the pressing pressure to the locking mechanism, and the second spring ensures the automatic rebound of the release button.

[0011] Pressing the release button triggers the linkage unlocking of the cone buckle mechanism, allowing for smooth one-handed folding of the two warning signs. The hinged rotation design ensures a smooth folding process, while the fixed plate, as the core load-bearing element, maintains structural stability. The elastic locking system, composed of connecting rods and springs, automatically resets upon unfolding. The entire transformation process requires no tools, significantly improving work efficiency at the bridge inspection site. The support rod achieves quick separation through the threaded engagement of the screw and connector. The plug-in structure of the base and connector simplifies the transportation and storage process, and the slot provides ample space for the connector to move without interference. This detachable structure allows the device to adapt to the loading space requirements of different vehicles, making it particularly suitable for bridge inspection teams that need to frequently relocate.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 A foldable warning sign for on-site inspection of highway bridges includes a first warning sign 1, a second warning sign 2 rotatably mounted on the right end of the first warning sign 1, slots 3 at the upper ends of both the first and second warning signs 2, a connector 4 fixedly mounted on the upper end of the first warning sign 1, a screw hole 5 at the right end of the connector 4, a support rod 6 fixedly mounted on the right end of the first warning sign 1, a screw 7 fixedly mounted on the left end of the support rod 6, and a base 8 fixedly mounted on the right end of the support rod 6. The support rod 6 is connected to the base 8 via a connecting seat 9. The first warning sign 1 and the second warning sign 2 are connected in a foldable manner. Folding components are provided between the signs 2. The first warning sign 1 serves as the main display panel to show warning information. The second warning sign 2 expands the visibility range through rotation. The slot 3 provides a clearance for the connecting parts to avoid interference. The connector 4 enables quick docking between the support structure and the panel. The screw hole 5 ensures connection stability through thread engagement. The support rod 6 serves as the main load-bearing component to maintain the device in an upright working state. The screw 7 cooperates with the screw hole 5 to form a detachable connection. The base 8 increases the contact stability between the device and the ground. The connecting seat 9 optimizes the force transmission path between the support rod 6 and the base 8.

[0020] The folding assembly includes a fixing plate 10, which is fixedly installed between the first warning sign 1 and the second warning sign 2. The first warning sign 1 and the second warning sign 2 are connected by a hinge 11. A bottom ring 13 is fixedly installed at the upper end of the fixing plate 10, and a release button 12 is movably installed at the upper end of the bottom ring 13. The fixing plate 10 serves as the core skeleton of the folding mechanism to maintain the integrity of the structure. The hinge 11 provides relative rotational freedom for the warning signs 1 and 2. The bottom ring 13 serves as the fixed base of the locking mechanism. The release button 12 triggers the unlocking procedure by pressing.

[0021] A connecting rod 14 is fixedly installed at the upper end of the first warning sign 1. A first cone buckle 15 is movably installed at the upper end of the connecting rod 14. A second cone buckle 16 is movably installed at the upper end of the connecting rod 14. A first spring 17 is fixedly installed between the first cone buckle 15 and the second cone buckle 16. A limit end 18 is fixedly installed at the lower end of the first cone buckle 15 and the second cone buckle 16. A convex ring 19 is fixedly installed at the lower end of the release button 12. A second spring 20 is fixedly installed between the release button 12 and the fixing plate 10. The connecting rod 14 provides an installation base for the cone buckle system. The first cone buckle 15 and the second cone buckle 16 constitute a bidirectional mechanical locking component. The first spring 17 provides an automatic reset force for the cone buckle mechanism. The limit end 18 controls the travel range of the cone buckle. The convex ring 19 transmits the pressing pressure to the locking mechanism. The second spring 20 ensures the automatic rebound function of the release button 12.

[0022] Working principle: The warning sign achieves its folding function through the hinge 11 connecting the first warning sign 1 and the second warning sign 2. When storage is required, the user presses the release button 12 on the upper end of the fixing plate 10, causing the convex ring 19 to press down on the limiting ends 18 of the first cone buckle 15 and the second cone buckle 16. At this time, the first spring 17 on the connecting rod 14 is compressed and undergoes elastic deformation, causing the first cone buckle 15 and the second cone buckle 16 to disengage from the constraint position of the bottom ring 13. At this time, the first warning sign 1 and the second warning sign 2 can rotate and fold relative to each other around the hinge 11. During the folding process, the slot 3 provides clearance space for the connecting piece 4. After folding, the screw 7 at the left end of the support rod 6 can be unscrewed from the screw hole 5 of the connecting piece 4 to achieve quick separation. The base 8 is detachably connected to the support rod 6 through the connecting seat 9. The entire folding process is complete. The folding process only requires one-handed operation of the release button 12 to complete the mechanical unlocking. When it needs to be unfolded for use, align the first cone buckle 15 and the second cone buckle 16 with the through hole at the upper end of the fixing plate 10. Under the action of the rebound force of the first spring 17, they automatically snap into the bottom ring 13 to form a mechanical lock. At this time, the second spring 20 pushes the release button 12 to return to the initial position. After the main body of the warning sign is unfolded, screw 7 is screwed into the screw hole 5 to realize the fastening connection between the support rod 6 and the first warning sign 1. The plug-in structure of the connecting seat 9 and the base 8 can quickly establish a stable support system. The fixing plate 10 in the folding assembly, as the core load-bearing component, ensures the structural rigidity of the two warning signs in the unfolded state. The rotational freedom design of the hinge 11 allows the first warning sign 1 and the second warning sign 2 to achieve a 180-degree planar unfolding or a 90-degree vertical working state.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
