Description

Technical Field

[0001] The utility model relates to the technical field of road sound insulation barriers, in particular to a semi-enclosed sound insulation screen. Background Art

[0002] With the development of my country's economy, the number of domestic cars has continued to rise, and the construction of urban roads, highways, intercity light rail, and high-speed rail has also entered a period of rapid development. However, while providing convenient transportation, the traffic noise it generates has also had an adverse impact on the health and lives of surrounding residents. Therefore, effectively preventing and controlling road noise pollution is not only an important environmental issue, but also a social issue that has attracted much attention from the public. Therefore, it has become a trend to continuously develop anti-drying and sound-insulating environmentally friendly products to isolate and eliminate noise from the source and transmission path of noise;

[0003] The existing semi-enclosed soundproof screen generally has a bending structure on the top of the barrier, and the inward-bending structure will occupy a part of the upper space of the road. When large vehicles are driving, they are prone to scratching the soundproof screen, which will cause traffic accidents. Therefore, we have launched a new semi-enclosed soundproof screen. Utility Model Content

[0004] The main purpose of the utility model is to provide a semi-enclosed sound insulation screen, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A semi-enclosed soundproof screen comprises a barrier body, a connecting block is fixedly connected to the middle part of the right end of the barrier body, a connecting groove is provided in the middle part of the left end of the barrier body, a first fixing plate is fixedly connected to the front part of the lower end of the barrier body, four first fixing holes are provided in the upper end of the first fixing plate, two supporting rods are fixedly connected to the lower part of the rear side of the outer surface of the barrier body, the lower ends of the two supporting rods are fixedly connected to the second fixing plate, and the upper ends of the two second fixing plates are provided with two second fixing holes.

[0007] Preferably, the four first fixing holes are equally spaced and distributed on the left and right sides and do not contact the barrier body.

[0008] Preferably, the two support rods are distributed left and right and do not touch each other.

[0009] Preferably, the two support rods are both arranged at an incline.

[0010] Preferably, the two second fixing plates are not in contact with the barrier body.

[0011] Preferably, the two support rods are respectively located between the two second fixing holes in the two second fixing plates and do not contact each other.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by setting a layer of arc structure on the barrier body, when the device is fixedly installed on the roadside for use, the arc structure of the barrier body will cause the overall use position of the device to retract, so as to prevent the bent part of the barrier body from extending into the upper space of the road, and to prevent large vehicles from scratching the device when driving;

[0014] 2. In the utility model, two support rods are fixedly connected to the rear of the outer surface of the barrier body. When the device is fixedly installed and used, the two support rods can play a role of stable support, avoiding the device with the center of gravity at the rear from tilting or falling during use, which can improve the safety of the device;

[0015] 3. In the utility model, a connection groove is opened at the left end of the barrier body, and a connection block is fixedly connected to the right end of the barrier body. When multiple devices are used in combination, they can be tightly connected to each other through the connection block and the connection groove, so that the multiple devices can be connected more closely, and the positioning of the unfixed devices can be facilitated, making the installation more convenient.

By providing the barrier body 1 with an arc structure, when the device is fixedly installed on the roadside for use, the arc-shaped barrier body 1 will cause the overall use position of the device to retract, thereby preventing the bent part of the barrier body 1 from extending into the upper space of the road, and preventing large vehicles from scratching the device when driving.

[0028] It should be noted that the utility model is a semi-enclosed soundproof screen. By providing a layer of arc structure in the barrier body 1, when the device is fixedly installed on the roadside for use, the arc-shaped barrier body 1 will cause the overall use position of the device to retract, thereby preventing the bent part of the barrier body 1 from extending into the upper space of the road, and preventing large vehicles from scratching the device when driving. At the same time, two support rods 6 are fixedly connected to the rear part of the outer surface of the barrier body 1. When the device is fixedly installed for use, the two support rods 6 can play a role of stable support, thereby preventing the device with a rear center of gravity from tilting or tipping during use, and thus improving the safety of the device. In addition, by providing a connecting groove 3 at the left end of the barrier body 1 and fixing a connecting block 2 at the right end of the barrier body 1, when multiple devices are used in combination, they can be tightly connected to each other through the connecting block 2 and the connecting groove 3, so that the multiple devices can be connected more tightly, and it is also convenient to position the unfixed devices, so that the installation can be more convenient.
