Description

Technical Field

[0001] This utility model belongs to the field of road safety devices, and in particular relates to an anti-collision and anti-theft isolation device for separating pedestrians and vehicles on roads. Background Technology

[0002] With the increasing demands for urban traffic management and public safety, pedestrian-vehicle separation devices are widely used as important traffic safety facilities in densely populated areas such as schools, scenic spots, and commercial districts. Existing technologies commonly employ three main types of pedestrian-vehicle separation devices: fixed concrete blocks, movable metal barriers, and rising road barriers. However, each of these devices has limitations to varying degrees in practical use.

[0003] While fixed concrete barriers offer structural stability, their permanent installation means they cannot be repositioned for temporary traffic control needs, and removal requires damage to the ground structure and is not reusable. Movable metal barriers offer some flexibility, but generally suffer from insufficient weight and weak impact resistance, making them prone to structural deformation or displacement upon vehicle impact, posing serious safety hazards. While lift-type road barriers can address both fixed and movable requirements, their complex electromechanical control systems result in high manufacturing costs, and their reliance on electric power limits their applicability during power outages or in inclement weather.

[0004] Existing products generally suffer from unreasonable ground connection structure design, mainly manifested in insufficient pre-embedding depth and low shear strength of connectors, making them ineffective against sudden impacts. Furthermore, traditional devices generally lack reliable anti-theft locking mechanisms, making them vulnerable to unauthorized disassembly or relocation in important locations, failing to meet security requirements. Regarding functional expandability, existing products struggle to simultaneously meet multiple requirements such as rapid disassembly and reassembly, reusability, and road surface restoration. Particularly after temporary traffic control measures end, the removed sections often leave road surface depressions or exposed connectors, affecting pedestrian safety and urban landscape harmony. These technical deficiencies severely restrict the effectiveness of pedestrian-vehicle separation devices in dynamic traffic management. Utility Model Content

[0005] In view of this, the present invention aims to propose an anti-collision and anti-theft isolation device for the separation of pedestrians and vehicles on roads, so as to solve the problems of weak anti-collision performance, inability to be quickly disassembled and reused, lack of anti-theft function, and damage to road surface smoothness after removal of traditional pedestrian and vehicle separation devices.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a collision-proof and anti-theft isolation device for separating pedestrians and vehicles on roads, comprising an isolation pile body, a pre-embedded cylinder, a connector, a connecting screw, and a lock body. The isolation pile body has a connecting channel along its axial center, which extends through both the upper and lower ends of the isolation pile body. The pre-embedded cylinder is pre-embedded underground, and a connector is provided inside the pre-embedded cylinder. The connector has a connecting hole with an internal thread, and the connecting hole corresponds to the position of the connecting channel. The connecting screw is inserted into the connecting channel, and the lower end of the connecting screw is externally threaded and screwed to the internal thread of the connecting hole. A locking groove is provided on the upper rod side of the connecting screw. A lock body is provided inside the isolation pile body, and the locking tongue of the lock body corresponds to the position of the locking groove, with the locking tongue extending out and engaging with the locking groove.

[0007] Furthermore, the embedded cylinder is a seamless pipe.

[0008] Furthermore, the locking groove has a ring-shaped structure.

[0009] Furthermore, the keyhole of the lock body is located on the upper end face of the isolation pile body.

[0010] Furthermore, the upper end of the connecting screw is provided with a countersunk hole, and the shape of the wrench head corresponds to the shape of the countersunk hole.

[0011] Furthermore, the shape of the countersunk hole is an inner triangle, an inner square, or an inner hexagon.

[0012] Furthermore, the isolation pile body is a cylindrical or spherical structure.

[0013] Furthermore, the shell of the isolation pile is made of metal, and the inside of the shell is filled with concrete.

[0014] Furthermore, the isolation pile body includes a lower shell and an upper cover plate. The lower shell has a hollow cavity structure, and the upper cover plate rotates to cover the upper shell.

[0015] Furthermore, a vibration sensor is installed inside the isolation pile, and the vibration sensor is electrically connected to the alarm.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This invention, through the threaded connection between the pre-embedded cylinder and the connecting screw, rigidly connects the gravity of the isolation pile to the underground pre-embedded structure. When facing impact, the isolation pile and the connecting screw share the force. The screw penetrates the isolation pile and is tightly connected to the pre-embedded cylinder, dispersing the impact force to deeper underground layers through the connecting screw. This effectively prevents the device from tipping over or shifting, significantly improving the device's stability against vehicle impacts. Compared to traditional shallow fixing methods, this structure maintains its integrity under impact, avoiding failure problems caused by broken connecting parts.

[0017] This utility model adopts a modular, split design, with the isolation pile, embedded cylinder, and connecting screw rod being independent of each other. Disassembly simply requires releasing the locking relationship between the locking body and the connecting screw rod, then using a special wrench to loosen the connecting screw rod to quickly remove the isolation pile from the ground. The embedded cylinder remains flush with the ground, avoiding leaving pits or protrusions after removal. This structural design not only meets the flexible needs of temporary control but also enables rapid reinstallation, ensuring efficient reuse of the device in different scenarios.

[0018] This invention features a lock body that engages with the locking groove of the connecting screw to form a dual locking mechanism. When the lock tongue is engaged in the locking groove, it prevents unauthorized personnel from rotating the screw to disassemble the device and also limits the relative displacement between the stake and the embedded structure. This design ensures reliable anti-theft performance even when unattended.

[0019] This utility model's isolation pile body adopts a composite structure with a metal shell and embedded concrete. While ensuring sufficient self-weight, the outer shell protective layer slows down the aging and cracking of the concrete. The embedded cylinder adopts a seamless pipe processing technology to eliminate stress concentration points at the weld seams and ensure corrosion resistance for long-term underground use.

[0020] In addition, the internal structure of the isolation pile of this invention can be left uncast with concrete, retaining a hollow structure that can be used to store emergency tools and other items, providing more functional expansion options. Vibration sensors can also be installed inside the isolation pile. When the vibration of the isolation pile exceeds a threshold range, it indicates that the pile has been impacted or has moved abnormally. In this case, the vibration sensor sends a signal to an alarm, prompting personnel to investigate. This structural layout does not affect the main strength of the device while achieving a functional upgrade from physical isolation to intelligent monitoring, meeting the needs of high-level security scenarios.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0037] See Figures 1-12This embodiment describes an anti-collision and anti-theft isolation device for separating pedestrians and vehicles on roads. It includes an isolation pile 1, a pre-embedded cylinder 2, a connector 3, a connecting screw 4, and a lock body 5. The isolation pile 1 has a connecting channel along its axial center, which extends through both the upper and lower ends of the isolation pile 1. The pre-embedded cylinder 2 is pre-embedded in the ground 8. The connector 3 is provided inside the pre-embedded cylinder 2. The connector 3 has a connecting hole with an internal thread, which corresponds to the position of the connecting channel. The connecting screw 4 is inserted into the connecting channel, and the lower end of the connecting screw 4 is externally threaded and screwed to the internal thread of the connecting hole. The upper rod side of the connecting screw 4 has a locking groove. The lock body 5 is provided inside the isolation pile 1. The locking tongue of the lock body 5 corresponds to the position of the locking groove, and the locking tongue extends out and engages with the locking groove.

[0038] In this embodiment, the isolation pile 1 has a through circular connecting channel along its axial center. The pre-embedded cylinder 2 is vertically embedded in the ground 8, and a connector 3 is fixed inside it. The connector 3 has an internal threaded hole at its center. The lower end of the connecting screw 4 is machined with an external thread. After passing through the channel of the isolation pile 1, the connecting screw 4 engages with the internal thread of the connector 3 and is tightened, forming a rigid connection between the isolation pile 1 and the pre-embedded cylinder 2. When facing an impact, the isolation pile 1 and the connecting screw 4 share the force. The impact force is dispersed to the deep underground layers through the connecting screw 4, effectively preventing the device from tipping over or shifting, and significantly improving the stability of the device against vehicle impacts. The upper part of the connecting screw 4 has a locking groove, and a lock body 5 is installed inside the isolation pile 1. When the locking tongue of the lock body 5 extends, it embeds into the groove, preventing the connecting screw 4 from moving up and down, and preventing unauthorized personnel from loosening and pulling out the connecting screw 4, thereby avoiding abnormal movement of the isolation pile 1. The device achieves stable fixation of the isolation pile 1 to the ground through a threaded connection. After the lock body 5 is locked, it prevents unauthorized disassembly, forming an anti-collision and anti-theft mechanism.

[0039] The embedded cylinder 2 described in this embodiment is a seamless pipe. The seamless pipe construction of the embedded cylinder 2 ensures high material versatility, low production costs, and a weld-free pipe wall structure, preventing weak points in the connection due to corrosion in the underground environment. The connector 3 is welded to the top of the inner cavity of the embedded cylinder 2, and when it engages with the threaded connection screw 4, the force is evenly distributed, improving long-term stability.

[0040] The locking groove described in this embodiment is an annular structure. The annular locking groove reduces the difficulty of locking the bolt and the connecting screw 4, allowing the lock body 5 to lock the connecting screw 4 at any rotation angle, ensuring anti-theft reliability.

[0041] In this embodiment, the keyhole of the lock body 5 is located on the upper end face of the isolation post 1. After the key 6 is inserted, it rotates to drive the lock tongue to extend and retract; when extended, it locks; when retracted, it unlocks.

[0042] In this embodiment, the upper end of the connecting screw 4 is provided with a countersunk hole, and the head shape of the wrench 7 corresponds to the shape of the countersunk hole. The shape of the countersunk hole is an inner triangle, an inner square, or an inner hexagon. A non-standard inner polygonal countersunk hole is opened at the top of the connecting screw 4, which is used to rotate the screw with the special wrench 7. This prevents disassembly with general-purpose tools and enhances anti-theft capabilities.

[0043] The isolation pile 1 described in this embodiment is a cylindrical or spherical structure, and the appropriate shape and structure can be selected according to the actual situation.

[0044] The shell of the isolation pile 1 described in this embodiment is made of metal to improve its service life, and the interior of the shell is filled with concrete to increase its overall weight. Furthermore, the exterior of the isolation pile 1 can also be coated with a protective paint layer, or reflective warning strips can be installed.

[0045] The isolation pile 1 described in this embodiment includes a lower shell and an upper cover plate. The lower shell has a hollow internal structure, and the upper cover plate rotates to cover the upper shell. Unlike isolation piles with internally poured concrete, the isolation pile 1 in this embodiment has a hollow internal structure. This hollow structure can be used to store emergency tools and other items. Although this method reduces the impact resistance, it improves the device's functional expansion capabilities, allowing it to be placed in areas with low impact risk and increasing its flexibility of use.

[0046] In this embodiment, a vibration sensor is installed inside the isolation pile 1, and the vibration sensor is electrically connected to an alarm. The vibration sensor detects the vibration state of the isolation pile 1. When the vibration of the isolation pile 1 exceeds a threshold range, it means that the isolation pile 1 has been impacted or has moved abnormally. At this time, the vibration sensor sends a signal to the alarm, and the alarm prompts personnel to check. This structural layout does not affect the main strength of the device, and can realize the functional upgrade from physical isolation to intelligent monitoring, meeting the needs of high-level security scenarios.

[0047] The specific embodiments of this utility model disclosed above are merely illustrative of the present utility model. These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
