Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of guardrails, especially to a movable guardrail for an opening of a highway median strip. BACKGROUND

[0002] Highways have the advantages of high speed, large traffic capacity, low transportation cost and driving safety, and have been favored by people since the day of their birth. As an important part of highways, the median strip has always been filled with garden trees and other garden plants. The median strip of the highway is set up at a certain distance and is closed in normal times, and can be moved to be used as an emergency exit in emergency situations.

[0003] The utility model patent with the application number 202323299276.8 discloses a movable guardrail for a central median strip of a highway. The movable guardrail for the central median strip of the highway can realize the storage of universal wheels through the cooperation of three mechanisms. After the movable guardrail is moved to a suitable position, the universal wheels are retracted to avoid bearing the weight of the whole for a long time and to prolong the service life of the universal wheels. At the same time, the movable guardrail is fixed to the road, which can effectively realize the stability of the whole and prevent the limitation of the whole installation. However, the above design lacks some protective measures during use. When the vehicle slides and the falling objects hit the movable guardrail, it often causes serious injury. The movable guardrail cannot buffer the impact, resulting in excessive impact force and causing serious damage to the device.

[0004] Therefore, it is necessary to provide a movable guardrail for an opening of a highway median strip to solve the above technical problems. UTILITY MODEL CONTENTS

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a movable guardrail for an opening of a highway median strip.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The movable guardrail for the opening of the highway median strip comprises a base, a first support provided above one end of the base, a second support provided above the other end of the base, a guardrail frame provided between the first support and the second support, a baffle provided in front of and behind the guardrail frame, a group of installation shells provided between the baffle and the guardrail frame, a sliding groove provided in the inside of the installation shell, a group of sliding blocks provided in the inside of the sliding groove, a connecting rod provided between the sliding blocks and the baffle, a rotating shaft provided between the two ends of the connecting rod and the baffle and the sliding block, a first spring provided on the side of the sliding groove close to the sliding block, a force relief assembly provided at the two ends of the installation shell, and a plurality of air bag pads provided on the surface of the baffle.

[0008] Preferably, a push rod is provided on one side of the slider, a push plate is provided inside the pressure relief assembly, the bottom end of the push plate extends through the outside of the pressure relief assembly, and a buffer spring is provided around the outside of the pressure relief assembly near the push plate.

[0009] Preferably, a fixing shell is provided on one side of the base, a limiting groove is provided inside the other side of the base, a limiting rod is provided inside the limiting groove, and a third spring is provided inside the limiting groove on the side near the limiting rod.

[0010] Preferably, a locking block is provided at the top of the limiting rod, a plurality of second springs are provided between the locking block and the limiting rod, and an extension rod is provided at the tail end of the limiting rod, one end of the extension rod passing through the limiting groove.

[0011] Preferably, a hinge is provided on one side between the bases, a set of bolts is provided at one end of the upper part of the base, the bolts pass through the base, a caster wheel is provided inside the base, and an electric push rod is provided at the top of the caster wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model utilizes a baffle, a connecting rod, a slider, and a first spring. When the baffle is subjected to a large external impact, the baffle presses against the guardrail frame and drives the connecting rod to rotate. Under the action of the rotating shaft, the connecting rod drives the slider to press against the first spring, thereby effectively dispersing the impact force on the baffle and preventing the impact force from directly hitting the movable guardrail, which could cause the movable guardrail to break or collapse, thus improving the effectiveness of the device.

[0014] (2) This utility model utilizes a force-relieving component. When the impact force on the baffle and connecting rod is too great, the slider drives the push rod to squeeze the push rod through the through hole. Under the action of the buffer spring, the force on the slider is dispersed to the outside by the push rod, thereby further buffering the external impact force, reducing damage to the movable guardrail, and improving the service life of the device.

[0015] (3) This utility model utilizes a fixed shell, a locking block, and a limiting rod. When the device is installed and fixed, the extension rod can be pushed to move the limiting rod towards the fixed shell. Under the action of the second spring, the locking block is engaged with the limiting hole of the fixed shell, thereby fixing the bases and preventing the movable guardrails from shaking. The installation is quick and convenient. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] Example 1

[0025] like Figures 1-6As shown, this utility model provides a movable guardrail for an opening in a highway median strip, comprising: a base 1; a first support 2 positioned above one end of the base 1; a second support 3 positioned above the other end of the base 1; a guardrail frame 4 positioned between the first support 2 and the second support 3; the guardrail frame 4, the first support 2, and the second support 3 forming a movable guardrail for convenient use on highways; baffles 5 positioned at both the front and rear of the guardrail frame 4 to protect it and reduce external impact; a mounting shell 8 positioned between the baffles 5 and the guardrail frame 4, mounted on the guardrail frame 4; a sliding groove 14 positioned inside the mounting shell 8; a set of sliders 12 positioned inside the sliding groove 14, allowing the sliders 12 to slide within the sliding groove 14; a connecting rod 10 positioned between the sliders 12 and the baffles 5; and a connecting rod 10 positioned between both ends of the connecting rod 10 and the baffles 5 and the sliders 12. Shaft 11 facilitates the rotation of connecting rod 10. A first spring 13 is located inside the slide groove 14 near the slider 12. When the baffle 5 experiences a large external impact, it presses against the guardrail frame 4, simultaneously rotating the connecting rod 10. Under the action of the shaft 11, the connecting rod 10 drives the slider 12 to slide towards both sides of the slide groove 14, pressing the first spring 13. This effectively disperses the impact force on the baffle 5, preventing the impact force from directly impacting the movable guardrail and causing damage or collapse, thus improving the device's effectiveness. Force-relieving components 9 are located at both ends of the mounting shell 8, further enhancing the dispersion of impact force and protecting the guardrail frame 4. Several airbags 6 are provided on the surface of the baffle 5, increasing its blocking force and elasticity, effectively reducing shock.

[0026] Example 2

[0027] like Figures 2-4 As shown, a push rod 17 is provided on one side of the slider 12. There is a through hole between the mounting shell 8 and the pressure relief assembly 9, which allows the push rod 17 to enter the interior of the pressure relief assembly 9 through the through hole. A push plate 16 is provided inside the pressure relief assembly 9. The bottom end of the push plate 16 extends through the outer side of the pressure relief assembly 9. A buffer spring 15 is provided around the outer side of the inside of the pressure relief assembly 9 near the push plate 16. When the impact force on the baffle 5 and the connecting rod 10 is too large, the slider 12 drives the push rod 17 to squeeze the push rod 16 through the through hole. Under the action of the buffer spring 15, the force on the slider 12 is dispersed to the outside by the push rod 16, thereby further buffering the external impact force, reducing damage to the movable guardrail, and improving the service life of the device.

[0028] Example 3

[0029] likeFigure 1 , Figure 5 As shown, a fixing shell 18 is provided on one side of the base 1. The fixing shell 18 has a limit hole on one side to facilitate the connection and fixation of subsequent devices. A limit groove 19 is provided inside the other side of the base 1. A limit rod 20 is provided inside the limit groove 19. The limit rod 20 slides inside the limit groove 19. A third spring 23 is provided inside the limit groove 19 near the limit rod 20. After the limit rod 20 is used, the third spring 23 can drive the limit rod 20 to automatically reset, making it more convenient to use.

[0030] Example 4

[0031] like Figure 5 As shown, a locking block 22 is provided at the top of the limiting rod 20, and several second springs 21 are provided between the locking block 22 and the limiting rod 20. The locking block 22 can be pressed up and down by the second springs 21 for convenient subsequent use. An extension rod 24 is provided at the tail end of the limiting rod 20. One end of the extension rod 24 passes through the limiting groove 19. When the device is installed and fixed, the extension rod 22 can be pushed, and the extension rod 22 drives the limiting rod 20 to move towards the fixed shell 18. Under the action of the second springs 21, the locking block 22 is engaged with the limiting hole of the fixed shell 18, thereby fixing the base 1 and preventing the movable guardrail from shaking. The installation is quick and convenient.

[0032] Example 5

[0033] like Figure 1 , Figure 5 As shown, a hinge 7 is provided on one side between the bases 1 to facilitate the opening, closing, and folding of each set of movable guardrails and to facilitate the movement of the guardrail frame 4. When the guardrail frame 4 is in use, the locking block 22 can be engaged with the limiting hole of the fixed shell 18 to achieve a fixed connection between the bases 1. A set of bolts 25 is provided at one end of the upper part of the base 1. The bolts 25 penetrate the base 1. When in use, the bolt slots can be fixed to the foundation, so that the bolts 25 are aligned with the bolt slots of the foundation for installation, thereby fixing the device. The interior of the base 1 is provided with casters 26. The top of the casters 26 is provided with an electric push rod 27. When it is necessary to disassemble the guardrail frame 4, the electric push rod 27 can be activated to drive the casters 26 downward to lift and move the guardrail frame 4. Under the action of the hinge 7, the device can be folded and stored to facilitate the opening of the partition strip, making it more convenient to use and avoiding the need to disassemble the guardrail step by step.

[0034] The working principle of the movable guardrail with openings in the highway median provided by this utility model is as follows:

[0035] In use, the guardrail frame 4, the first support 2, and the second support 3 form a set of movable guardrails, which are convenient for use on highways. When the baffle 5 is impacted by the outside, the baffle 5 presses against the guardrail frame 4, and at the same time drives the connecting rod 10 to rotate. Under the action of the rotating shaft 11, the connecting rod 10 drives the slider 12 to slide to both sides in the slide groove 14, and presses the first spring 13, thereby effectively dispersing the impact force on the baffle 5 and preventing the impact force from directly hitting the movable guardrail. At the same time, the force relief component 9 can further improve the dispersion of the impact force, thereby protecting the guardrail frame 4. When the impact force on the baffle 5 and the connecting rod 10 is too large, the slider 12 drives the push rod 17 to press the push rod 16 through the through hole. Under the action of the buffer spring 15, the force on the slider 12 is dispersed to the outside by the push rod 16, thereby further buffering the external impact force and reducing damage to the movable guardrail.

[0036] Furthermore, when installing and fixing the device, the extension rod 22 can be pushed, and the extension rod 22 drives the limiting rod 20 to move towards the fixed shell 18. Under the action of the second spring 21, the locking block 22 is engaged with the limiting hole of the fixed shell 18, thereby fixing the base 1 and preventing the movable guardrail from shaking. The installation is quick and convenient, and the bolt slot is fixed to the foundation, so that the bolt 25 is aligned with the bolt slot of the foundation for installation, thereby fixing the device. When it is necessary to disassemble the guardrail frame 4, the electric push rod 27 can be activated to drive the universal wheel 26 to move downward, and the guardrail frame 4 can be lifted and moved. Under the action of the hinge 7, the device can be folded and put away, making it convenient to open the partition strip and making it more convenient to use, avoiding the need to disassemble the guardrail step by step.

[0037] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
