Description

Technical Field

[0001] The utility model belongs to the technical field of isolation devices, and in particular relates to a road isolation structure. Background Art

[0002] In order to ensure the safety and smooth flow of traffic, and based on road conditions, traffic flow characteristics and the needs of road traffic management, safety isolation devices are usually set up on the road to control the road.

[0003] The Chinese patent with publication number CN220849099U discloses an assembled and portable road isolation device, including a main body, a combined storage mechanism and a base placement mechanism. The combined storage mechanism is arranged inside the main body, and the base placement mechanism is arranged at the bottom of the main body. The combined storage mechanism includes a storage slot, a rotating shaft, a folding frame, a placement hole and a connecting buckle, and the top of the storage slot is provided with a rotating shaft, one side of the rotating shaft is connected to a folding frame, and the inside of the folding frame is provided with a placement hole. The assembled and portable road isolation device can form a folding storage structure through two groups of folding frames, and then cooperate with the connecting buckle to form a road isolation frame body with adjustable spacing. Through this simple unfolding and storage structure, a portable and assembled isolation device structure is formed. When carrying, the user only needs to hold the handle to lift the entire device for moving. The installation and disassembly operation is convenient and easy to move and carry, which is conducive to use in a construction environment.

[0004] However, in actual use, although the folding frame can play a certain isolation role after being unfolded relative to the main body, there is no shielding structure in the space between the folding frame and the ground, that is, it is relatively empty, resulting in limited isolation effect of the folding frame, that is, poor isolation effect. Utility Model Content

[0005] The utility model aims to provide a road isolation structure to solve the problem of poor isolation effect of the existing isolation devices mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road isolation structure, comprising

[0007] A base, on which a plurality of positioning bolts are threadedly inserted;

[0008] The main rod is fixed on the base;

[0009] The isolation unit comprises two isolation components which are symmetrical with respect to the main rod, the isolation components comprising an isolation plate, a first connecting rod, a second connecting rod and a first rotating shaft, the two ends of the first rotating shaft are respectively connected to the first connecting rod and the second connecting rod for rotation, and the first connecting rod and the second connecting rod are provided with a first sliding groove, the first rotating shaft is slidably matched with the first sliding groove, one end of the first connecting rod and one end of the second connecting rod are both slidably mounted on the main rod, and the first connecting rod and the second connecting rod can both rotate relative to the main rod, the other end of the first connecting rod and the other end of the second connecting rod are both hinged to the isolation plate, and the first connecting rod and the second connecting rod are arranged crosswise in an "X" shape;

[0010] The limiting units are provided with two groups and are symmetrically installed at the upper and lower ends of the main rod. The limiting units are used to limit the positions of the first connecting rod and the second connecting rod.

[0011] The principle and effect of this technical solution:

[0012] 1. The base is installed on the ground through the positioning bolts, so that the main pole stands on the ground. By arranging the first connecting rod and the second connecting rod in an X shape, the space above the ground between the isolation plate and the main pole can be divided into multiple blocks after the isolation plate is unfolded, that is, the maximum passable space size of the object is reduced, so that the device has a better isolation effect after being unfolded. The isolation component is limited by the limiting component, so that the device can play the role of stable isolation and storage.

[0013] 2. The first connecting rod and the second connecting rod are respectively slidably mounted on the main rod and can rotate relative to the main rod, and the first rotating shaft and the first sliding groove are provided on the first connecting rod and the second connecting rod, so that a hinge structure is formed among the first connecting rod, the second connecting rod, the rotating shaft and the main rod. By controlling the position of the isolation plate, the first connecting rod and the second connecting rod can be rotated relative to the main rod and slide along the main rod at the same time, and the rotating shaft maintains the synchronization of the first connecting rod and the second connecting rod by sliding in the first sliding groove, so that the user can control the deployment and storage of the device by controlling the position of the isolation plate.

[0014] 3. By limiting the positions of the first connecting rod and the second connecting rod through the limiting unit, the position of the isolation plate can be kept stable, so that the device can be kept stable when unfolded and when stored.

[0015] The utility model is further configured as follows: the isolation component also includes a third connecting rod and a second rotating shaft, one end of the third connecting rod is hinged on the base, the other end of the third connecting rod is rotatably connected to the second rotating shaft, and the second rotating shaft is rotatably installed on the first connecting rod, a second sliding groove is opened on the first connecting rod, and the second rotating shaft slidably cooperates with the second sliding groove.

[0016] The principle and effect of this technical solution: through the setting of the third connecting rod, the second rotating shaft and the second sliding groove, a crank slider structure is formed between the first connecting rod, the third connecting rod and the second rotating shaft, so that the rotation of the first connecting rod can control the rotation of the third connecting rod, thereby achieving the effect of unfolding and storing, further dividing the space after the main board and the partition are unfolded, thereby enhancing the isolation effect of the device.

[0017] The utility model is further configured as follows: both upper and lower ends of the main rod side wall are provided with limit grooves, and sliders are slidably matched in the limit grooves, and the two sliders are respectively hinged to the first connecting rod and the second connecting rod.

[0018] The principle and effect of this technical solution: by setting the limit groove and the slider, the ends of the first connecting rod and the second connecting rod can slide relative to the main rod and can also rotate relative to the main rod, thereby satisfying the expansion function of the isolation component.

[0019] The utility model is further configured as follows: the cross section of the sliding block is T-shaped.

[0020] The principle and effect of this technical solution: the T-shaped slider makes the cross-sectional shape of the limiting groove also T-shaped, so that the slider can only slide up and down in the main rod and will not move away from the main rod, so that one end of the first connecting rod and the second connecting rod can only slide up and down on the main rod and cannot move away from the main rod, thereby maintaining the stability of the first connecting rod and the second connecting rod relative to the main rod.

[0021] The utility model is further configured as follows: the limit unit includes two limit assemblies arranged up and down, and the two limit assemblies correspond to limit slots at the same height, the limit assembly includes a mounting frame, an insertion rod, a pressure plate and a spring, the cross-section of the mounting frame is "T"-shaped, the mounting frame is fixed to the side wall of the main rod, the insertion rod is slidably inserted into the outer wall of the mounting frame, and one end of the insertion rod extends into the limit slot, the pressure plate is sleeved on the insertion rod and is located between the main rod and the mounting frame, and the pressure plate abuts against the outer wall of the main rod, the spring is sleeved on the insertion rod and abuts against the side of the pressure plate away from the main rod, and a carrying handle is installed at the end of the insertion rod away from the main rod.

[0022] The principle and effect of the technical solution are as follows: by slidingly inserting the insertion rod and the mounting frame, and extending the insertion rod into the limit groove, the insertion rod can enter or leave the limit groove by sliding, so that the insertion rod can play a role in abutting and limiting the movement of the slider, and then by setting two sets of limit components, the expansion or storage position of one of the first connecting rod and the second connecting rod can be limited and controlled (the two limit units can respectively control the expansion or storage position of the two sliders at the same time, and this example only considers the isolation component on one side, and actually one limit unit controls the isolation components on both sides), and by setting the pressure plate and the spring, when the external force is lost, the rebound force of the spring will drive the pressure plate close to the main rod, so that the insertion rod enters the limit groove, so that the insertion rod can stably limit the position of the slider, so that the device is more stable when in use, and the setting of the handle makes it easier for the user to control the insertion rod to leave the limit groove.

[0023] The utility model is further configured as follows: a guide sliding surface is formed on one end of the insertion rod close to the limiting groove.

[0024] The principle and effect of this technical solution: the setting of the guide surface enables the slider to drive the insertion rod away from the limit groove by pressing when it moves to expand or store, thereby making way for the sliding of the slider, and under the elastic force of the spring, when the slider leaves the insertion rod, the insertion rod can automatically reset, thereby limiting the position of the slider, that is, making the slider in a stable expansion or storage position, thereby providing a stable isolation function and keeping it stable when carrying.

[0025] The utility model is further configured as follows: in a limiting unit, the cross-sectional shape of the end portion of the insertion rod away from the middle portion of the main rod is an isosceles trapezoid.

[0026] The principle and effect of this technical solution: by making the end of the plug rod away from the middle of the main rod in a limit unit into an isosceles trapezoidal shape, no matter when the isolation plate is stored or expanded, the slider can force the plug rod to give way to the slider by pressing against the inclined surface of the plug rod, so that the plug rod on this side does not need to be positionally controlled when it is expanded or stored, making the operation during expansion or storage more convenient, and due to the setting of the spring, although shaking during storage may force the slider to press against the guide surface of the plug rod, the elastic force of the spring will limit the position of the plug rod, and then under non-human control, the isolation plate is not easy to be expanded when carried in the stored state, that is, the stability is better.
