Description

Technical Field

[0001] This utility model relates to the field of safety warning sign technology, and in particular to an anti-theft power sign. Background Technology

[0002] In the operation of power systems, power identification signs are important warning components to ensure the safety of facilities and personnel. They are often set up in areas such as substations, transmission line towers, and cable well entrances to indicate the attributes of power facilities, warn non-workers to stay away, and help operation and maintenance personnel quickly identify facility information. Currently, most power signs are installed by bolt fixing or wire binding. When bolt fixing is used, it is a common fixing structure, which can be easily removed with ordinary wrenches, screwdrivers and other tools, which can easily lead to the loss or damage of the signs. The fixing strength of wire binding is insufficient, and after long-term use, it will break due to rust, weathering or external pulling, resulting in frequent signs falling off. This not only renders the signage ineffective as a warning, but the detached signage may also cause safety hazards such as short circuits and pedestrian tripping, and frequent replacements also increase the maintenance burden.

[0003] To address the shortcomings of the existing technologies, a power identification sign that is easy to install and has reliable anti-theft performance is designed to solve the problems encountered in the current use of power identification signs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies in terms of poor anti-theft performance, and to propose an anti-theft power identification sign.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-theft power identification sign, comprising sign I and sign II; Four fixing cylinders are fixedly connected to the four corners of the back of the sign II, and a connecting rod is provided inside the fixing cylinder; Four connecting cylinders are fixedly connected to the four corners of the back of the sign I and correspond one-to-one with the fixed cylinders. The four connecting rods are respectively inserted into the connecting cylinders. The inner wall of the connecting cylinder is provided with a guide groove, and the outer wall of the connecting rod is provided with a guide rod that cooperates with the guide groove.

[0006] In one possible design, a limiting ring is fixedly connected to the inner wall of the fixed cylinder, and an annular boss is fixedly connected to the outer wall of the connecting rod. A limiting ring groove is formed on the outer wall of the annular boss, and the limiting ring is located in the limiting ring groove to achieve rotational connection. A torsion spring is sleeved on the outer wall of the connecting rod, and the two ends of the torsion spring are respectively connected to the inner wall of the fixed cylinder and the annular boss. The torsion spring provides a restoring force for the connecting rod.

[0007] In one possible design, the guide groove includes a guide thread groove and a guide ring groove, both of which are formed on the inner wall of the connecting cylinder. The end of the guide thread groove is connected to the beginning of the guide ring groove. The guide thread groove guides the rotation of the connecting rod, and the guide ring groove achieves locking.

[0008] In one possible design, the first end of the guide thread groove is chamfered, and the chamfer is used to guide the guide rod into the guide thread groove.

[0009] In one possible design, the arc angle of the guide ring groove is smaller than that of the guide thread groove.

[0010] In one possible design, a limiting arc groove is provided at the end of the fixed cylinder, and a limiting block is fixedly connected to the outer wall of the connecting rod. The limiting block is located in the limiting arc groove and is used to limit the rotation angle of the connecting rod to prevent the guide rod from being misaligned.

[0011] In one possible design, the outer wall of the connecting cylinder has an insertion hole that communicates with the end of the guide ring groove, and one end of the guide rod slides into the connecting rod and is provided with a compression spring.

[0012] In this application, during actual use, sign I is fastened to the existing mounting bracket or wire mesh via the connecting cylinder on its back. Then, sign II is fastened from the other side. Specifically, the connecting rod is aligned with the corresponding connecting cylinder and inserted. At this time, the end of the guide rod will enter the interior of the guide thread groove. The guide rod will rotate along the connecting rod and move along the guide thread groove until the end of the guide rod moves to the connection between the guide thread groove and the guide ring groove. Then, the connecting rod is reset by the torsion spring, causing it to drive the guide rod to rotate in the opposite direction until it touches the end of the guide ring groove and stops. This completes the connection and assembly of sign I and sign II, allowing them to be installed on the bracket or wire mesh. When disassembly is required, workers use a thin metal rod or other tool to insert it into the socket and squeeze the guide rod to retract it into the connecting rod, thereby disengaging it from the guide ring groove. At this time, the connecting rod will continue to rotate and reset through the torsion spring, causing the guide rod to be displaced from the guide ring groove. After releasing the remaining fixing cylinder and connecting cylinder limit connections in the above manner, sign I and sign II can be directly disassembled and separated.

[0013] In this utility model, the chamfer at the beginning of the guide thread groove can guide the guide rod to quickly align and enter the groove, thus facilitating the actual installation operation. During installation, only the connecting rod needs to be inserted into the connecting cylinder, and the locking is achieved by the automatic reset of the torsion spring. There is no need to carry complicated tools such as wrenches and screwdrivers. In this utility model, the angle difference between the guide thread groove and the guide ring groove makes the disassembly process only require simple special tools such as thin metal rods. After inserting them into the insertion hole and squeezing the guide rod, the torsion spring can reset them and make them offset from each other, thereby directly releasing the lock. In this utility model, when in use, a separate clamping structure of sign I and sign II is adopted, and with its automatic locking mechanism, it is different from the bolt and other installation structures currently on the market. This avoids common theft methods such as bolt disassembly and wire damage, thereby reducing the probability of sign loss or damage and ensuring the continuous effectiveness of the power warning function.

[0016] 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.

[0017] In one embodiment: Reference Figure 1-3 A signboard, comprising: signboard I1 and signboard II2, both of which have corresponding sign patterns or text on their front sides and are arranged opposite each other to form a clamping structure; Four fixing cylinders 3 are fixed to the four corners of the back of sign II2, and the connecting rods 7 are housed inside. Four connecting cylinders 11 are fixed to the four corners of the back of sign I1, corresponding one-to-one with the fixing cylinders 3, and are used to receive the connecting rods 7 to achieve docking between the two.

[0018] refer to Figure 4 The guide groove 13 is formed on the inner wall of the connecting cylinder 11 and consists of a guide thread groove 1311 and a guide ring groove 1312, which are connected. The first end of the guide thread groove 1311 is provided with a chamfer 1313. The guide rod 6 is fixed to the outer wall of the connecting rod 7 and is adapted to the guide groove 13 to provide guidance for the insertion and rotation of the connecting rod 7.

[0019] The limiting ring 4 is fixed to the inner wall of the fixed cylinder 3, and the annular boss 8 is fixed to the outer wall of the connecting rod 7 and has a limiting ring groove. The limiting ring 4 is embedded in the limiting ring groove to realize the rotational connection between the connecting rod 7 and the fixed cylinder 3. The torsion spring 9 is sleeved on the outer wall of the connecting rod 7, and its two ends are respectively connected to the inner wall of the fixed cylinder 3 and the annular boss 8, which are used to store and release elastic potential energy. The limiting block 5 is fixed to the outer wall of the connecting rod 7, and the limiting arc groove 10 is opened at the end of the fixed cylinder 3. The limiting block 5 is located in the limiting arc groove 10 to limit the rotation angle of the connecting rod 7.

[0020] The cooperation between the guide thread groove 1311 and the guide rod 6 allows the connecting rod 7 to rotate synchronously during insertion. The chamfer 1313 at the beginning of the guide thread groove 1311 can guide the guide rod 6 to quickly enter the groove.

[0021] The engagement of the limiting ring 4 and the annular boss 8 effectively restricts the axial movement of the connecting rod 7, ensuring that the connecting rod 7 can only rotate around its own axis.

[0022] The torsion spring 9 stores elastic potential energy when the connecting rod 7 rotates, providing power for subsequent reset and locking. No additional locking force is required, achieving automatic locking and improving installation efficiency. The cooperation between the limit block 5 and the limit arc groove 10 can prevent the connecting rod 7 from rotating excessively and avoid the guide rod 6 from being misaligned and dislodged from the guide groove 13.

[0023] Specifically, during installation, first fasten the sign I1 to one side of the preset mounting carrier, such as an iron bracket, through the connecting tube 11 on the back. Then, bring the sign II2 closer from the other side of the carrier, so that the connecting rod 7 inside the fixing tube 3 is aligned with the opening of the corresponding connecting tube 11 and inserted. Guide rod 6 enters guide thread groove 1311 under the guidance of chamfer 1313. As connecting rod 7 continues to be inserted, guide rod 6 drives connecting rod 7 to rotate under the lateral force of guide thread groove 1311. Annular boss 8 rotates synchronously and squeezes torsion spring 9, so that torsion spring 9 stores elastic potential energy. When the guide rod 6 moves to the connection between the guide thread groove 1311 and the guide ring groove 1312, the torsion spring 9 releases its elastic potential energy to drive the connecting rod 7 to rotate in the opposite direction. The guide rod 6 then enters the guide ring groove 1312 and moves to the end of the groove. The connecting rod 7 stops rotating, completing the locking of the fixing cylinder 3 and the connecting cylinder 11. This clamps the identification plate I1 and the identification plate II2 onto the installation carrier, completing the installation operation. Because it is an internal locking structure, it cannot be removed from the outside, thus achieving the anti-theft effect.

[0024] This application can be used in the field of safety warning signs, or in other fields applicable to this application.

[0025] In another embodiment: Reference Figure 2-3An anti-theft power identification sign is used to facilitate subsequent disassembly operations. It is applied to the field of safety warning signs. The structure of this embodiment is basically the same as that of the previous embodiment, except that: the outer wall of the connecting cylinder 11 is provided with an insertion hole 12, which is connected to the end of the guide ring groove 1312 to provide an operating channel for external tools. One end of the guide rod 6 extends slidably into the interior of the connecting rod 7. A compression spring is provided between the guide rod 6 and the inner wall of the connecting rod 7 to provide outward elastic support force for the guide rod 6.

[0026] During dismantling, maintenance personnel arrive at the site with special tools such as thin metal rods. First, they locate the insertion hole 12 on the outer wall of the connecting cylinder 11, insert the thin metal rod into the insertion hole 12, until the end of the thin rod contacts the guide rod 6 and applies axial pressure. The guide rod 6 overcomes the spring force and retracts into the connecting rod 7, completely disengaging from the limit of the guide ring groove 1312. At this point, the torsion spring 9 releases its remaining elastic potential energy, causing the connecting rod 7 to continue rotating and resetting, so that the guide rod 6 is displaced from the guide ring groove 1312. Then, the sign II 2 is pulled away from the sign I 1. The connecting rod 7 drives the guide rod 6 to slide against the inner wall of the connecting cylinder 11 until the connecting rod 7 is completely separated from the connecting cylinder 11, thus detaching the connection at this part and completing the removal operation. This removal method is different from the commonly used one, and the removal position is located between the two signs, making it difficult to start, thereby achieving the effect of anti-theft.

[0027] Furthermore, the orientation of the socket 12 is preferably to the side or downward to prevent rainwater from entering the connection.

[0028] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
