Description

Technical Field

[0001] The utility model relates to the field of road surface anti-collision facilities, in particular to a road isolation anti-collision barrel. Background Art

[0002] Crash barrels are mainly installed on highways and urban roads where cars are prone to collide with fixed facilities on the road. They play an isolating role. Crash barrels are made of highly elastic and high-strength modified plastics. When a car collides with the equipment, it can effectively reduce the impact force.

[0003] Most of the existing crash buckets are barrel-shaped structures and are filled with liquid or fine sand. When a car collides with the device, the internal filler is used to absorb and reduce the impact force generated by the car collision, and the crash bucket can also absorb the impact force during the deformation process. However, the filler inside the crash bucket is quickly discharged outward when the crash bucket is suddenly impacted in the closed state, and cannot provide effective support. The crash bucket deforms too quickly and cannot provide effective buffering effect. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0005] Most of the existing crash buckets are barrel-shaped structures and are filled with liquid or fine sand. When a car collides with the device, the internal filler is used to absorb and reduce the impact force generated by the car collision, and the crash bucket can also absorb the impact force during the deformation process. However, the filler inside the crash bucket is quickly discharged outward when the crash bucket is suddenly impacted in the closed state, and cannot provide effective support. The crash bucket deforms too quickly and cannot provide effective buffering effect.

[0006] In order to solve the problems existing in the prior art, the utility model provides a road isolation and anti-collision barrel, including a barrel body, a cover is provided on the top of the barrel body, a partition is installed on the inner wall of the barrel body, a perforation is opened on the surface of the partition, a connecting cone is installed at the bottom of the partition, and a groove is opened on the surface of the barrel body.

[0007] The utility model provides a road isolation anti-collision barrel.

[0008] Furthermore, at least three partitions are installed on the inner wall of the barrel body, and there is a gap between each partition.

[0009] Furthermore, each partition plate surface is semicircular and has a plurality of perforations.

[0010] Furthermore, a mounting hole is opened on the surface of the partition, and a connecting cone is arranged at the bottom of the mounting hole.

[0011] Furthermore, each of the partitions is arranged in an interlaced manner.

[0012] Furthermore, the grooves opened on the surface of the barrel body are located near the gap between every two partitions, and the grooves are all located on one side of the barrel body. Each group of grooves consists of four grooves with a depth of half the thickness of the barrel body wall.

[0013] Furthermore, the connecting cone is made entirely of rubber material, the hardness of the rubber material gradually decreases from top to bottom, and the opening at the lower end is arranged in a valve shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model places fillers into the barrel body and then closes the cover, and the fillers gradually flow downward through the perforations and the connecting cone inside the barrel body until the barrel body is filled. When the barrel body is subjected to impact force, the internal fillers first flow upward along the perforations and the connecting cone. During this process, the fillers are blocked by the partitions and the passing speed is slow. When the impact force is large, the material flows upward quickly and squeezes the connecting cone. The material closed by the connecting cone can only move upward through the perforations. When the pressure inside the barrel body is too large, the grooves on the surface thereof burst and the fillers flow out, ensuring that the fillers have a certain degree of support while absorbing the impact when subjected to impact, and can quickly absorb the impact force through the barrel body bursting when the impact intensity is large.

[0020] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] like Figure 1-3As shown, a road isolation crash bucket comprises a barrel body 1, a cover 2 is arranged on the top of the barrel body 1, a partition 3 is installed on the inner wall of the barrel body 1, at least three partitions 3 are installed on the inner wall of the barrel body 1, gaps are left between each partition 3, a perforation 4 is opened on the surface of the partition 3, and a plurality of perforations 4 are arranged in a semicircular shape on the surface of each partition 3, a connecting cone 5 is installed at the bottom of the partition 3, a mounting hole is opened on the surface of the partition 3, and the connecting cone 5 is arranged at the bottom of the mounting hole, and each of the partitions 3 is staggered with each other, and the connecting cone 5 is made of rubber material as a whole, and the hardness of the rubber material gradually decreases from top to bottom, and the lower end opening thereof is arranged in a valve shape, a groove 6 is opened on the surface of the barrel body 1, and the groove 6 opened on the surface of the barrel body 1 is located near the gap between each two partitions 3, and the grooves 6 are all located on one side of the barrel body 1, and each group of grooves 6 consists of four grooves with a depth of half the wall thickness of the barrel body 1.

[0024] Working principle: After the filler is placed inside the barrel body 1, the cover 2 is closed, and the filler gradually flows downward through the perforation 4 and the connecting cone 5 inside the barrel body 1 until it fills the inside of the barrel body 1. When the barrel body 1 is subjected to impact force, the internal filler will first flow upward along the perforation 4 and the connecting cone 5. During this process, the filler is blocked by the partition 3, and the passing speed is slow. The barrel body 1 deforms relatively slowly. When the impact force is large, the material flows upward quickly and squeezes the connecting cone 5. The connecting cone 5 is closed and the filler can only move upward through the perforation 4. When the pressure inside the barrel body 1 is too large, the groove 6 on its surface breaks and the filler flows out, and the barrel body 1 deforms quickly to absorb the impact force.

[0025] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
