Description

Technical Field

[0001] The utility model relates to the technical field of sound absorbing barriers, in particular to a sound absorbing barrier which is easy to install. Background Art

[0002] A highway refers to a road specifically used for high-speed vehicles and is one of the important transportation infrastructures in many countries. A sound-absorbing barrier is a wall-like structure used to reduce the impact of traffic noise along the highway on nearby residents. It is classified according to material types, including metal sound barriers, concrete sound barriers, prestressed concrete sound barriers, fiberglass sound barriers, and other types.

[0003] In some existing sound-absorbing barriers, the sound-absorbing panels are usually integrated with the base plate. When the sound-absorbing panels are damaged, the entire sound-absorbing barrier needs to be replaced. Since the base plate is fixed to the high-speed ground, it is troublesome to replace the sound-absorbing panels. In addition, when assembling two sound-absorbing barriers of this type, multiple bolts need to be turned, which is troublesome.

[0004] Therefore, those skilled in the art provide a sound absorbing barrier that is easy to install to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a sound-absorbing barrier that is easy to install. By setting a fixing mechanism and a sound-absorbing mechanism, it is more convenient to disassemble the sound-absorbing plate. By setting L-shaped blocks and L-shaped holes, multiple sound-absorbing barriers can be quickly connected together, making it more convenient to assemble.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sound-absorbing barrier that is easy to install, comprising a sound-absorbing mechanism and a fixing mechanism, the sound-absorbing mechanism comprising a sound-absorbing plate, two fixing plates, a plurality of arc-shaped blocks, two slide plates and a hand-pull plate, three L-shaped blocks are fixedly arranged on the rear end surface of the sound-absorbing plate, three L-shaped holes are opened on the front end surface of the sound-absorbing plate, a water guide plate is fixedly arranged on the upper end surface of the sound-absorbing plate, three first sliding grooves are opened on the end surfaces of the two fixing plates on opposite sides, and first return springs are fixedly arranged between the plurality of arc-shaped blocks and the plurality of sliding grooves;

[0007] The fixing mechanism includes a base plate, an I-shaped groove, two sliding blocks, a pressing plate and two cylinders. A second sliding groove is opened on the lower side of one end surface of the base plate. Limiting rods are fixedly arranged on the front and rear sides of the bottom of the second sliding groove. Three second return springs are fixedly arranged between the lower end surface of the pressing plate and the bottom surface of the second sliding groove.

[0008] When the two sliders cannot slide any further, even if the end faces of the sliders do not contact the end faces of the sound absorbing plates, the hand-pulling plate can be pulled to one side while the sound absorbing plates are held and moved, so that the L-shaped block on the surface of the sound absorbing plates leaves the L-shaped hole of the other sound absorbing plates. When the sound absorbing plates are installed as a whole, the L-shaped block on the surface of the sound absorbing plates is pushed into the L-shaped hole. During the pushing process, the L-shaped block contacts the arc-shaped block inside the other sound absorbing plates, thereby pushing the arc-shaped block into the first sliding groove. After being fully pushed in, the arc-shaped block is pushed back to its original position under the action of the first return spring, so that the end faces of the arc-shaped block contact the L-shaped block, thereby connecting the two sound absorbing plates together.

[0009] Furthermore, the I-shaped groove is provided on the upper side of the end surface of one side of the bottom plate, and the lower end of the sound absorbing plate is clamped and arranged inside the I-shaped groove;

[0010] Through the above technical solution, the bottom plate and the sound absorbing plate can be fixed together by clamping the sound absorbing plate in the I-shaped groove. At this time, the bottom plate and the high-speed ground are fixed together, and the noise can be absorbed by the sound absorbing plate.

[0011] Furthermore, the two fixing plates are respectively fixedly arranged on the front sides of the end faces of the sound absorbing plate, and the plurality of arc-shaped blocks are respectively slidably arranged between the inner bottom surfaces and the inner top surfaces of the plurality of first sliding grooves;

[0012] Through the above technical solution, the arc block is limited by the first sliding groove, so that the arc block can be more stable when sliding.

[0013] Furthermore, the two slides are respectively fixedly connected to the plurality of arc-shaped blocks, the front end of the hand-pull plate is fixedly connected to a lower end of one side of the two slides, and the upper ends of the two slides are connected by a U-shaped plate;

[0014] Through the above technical solution, by pulling the hand-pull plate, the two slides on the surface of a sound absorbing plate can be driven to move together, and the other end of the hand-pull plate is abutted against the slide of another sound absorbing plate, so that the hand-pull plate can be pulled to drive the three slides to move.

[0015] Furthermore, the two sliders are respectively clamped and arranged on opposite sides of the outer end surfaces of the two limit rods, and the two sliders are both slidably connected to the lower end of the sound absorbing plate;

[0016] Through the above technical solution, the slider is limited by the limiting rod, so that the slider is more stable when moving.

[0017] Furthermore, the pressing plate is slidably arranged between the lower sides of the outer end surfaces of the two limiting rods, and the two lower end surfaces of the cylinders are respectively fixedly arranged at the front side and the rear side of the upper end surface of the pressing plate;

[0018] Through the above technical solution, the pressing plate is limited by the limiting rod, so that the pressing plate is more stable when moving, and the pressing plate can be squeezed to drive the cylinder on its surface to leave the interior of the slider, thereby releasing the clamping of the slider.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a sound-absorbing barrier which is easy to install. By pushing a pressing plate downwards while holding two sliders and moving them to opposite sides, when the pressing plate is pushed, the two cylinders on the surface of the pressing plate leave the inside of the two sliders, that is, the fixation of the two sliders is released. When the two sliders cannot move, the pulling of the pressing plate is released, and then the hand-pull plate is pulled backward while the sound-absorbing plate is moved to one side, so that the sound-absorbing plate can be removed, making it more convenient to replace the sound-absorbing plate.

[0021] 2. The utility model provides a sound-absorbing barrier that is easy to install. The L-shaped block on the surface of the sound-absorbing board is manually pushed into the L-shaped hole opened in another sound-absorbing board. During the pushing process of the L-shaped block, the L-shaped block abuts against the arc-shaped block, thereby squeezing the arc-shaped block into the interior of the first sliding groove. When the L-shaped block completely enters the L-shaped hole, the arc-shaped block is pushed back to its original position by the rebound force of the first return spring, so that the end face of the arc-shaped block abuts against the L-shaped block, thereby fixing the two sound-absorbing boards together, making it more convenient to assemble.

The lower end surfaces of the two cylinders 207 are respectively fixedly arranged at the front and rear sides of the upper end of the pressing plate 206.

[0032] When the sound absorbing plate 101 is replaced at high speed, the pressing plate 206 is pushed downward while the two sliders 205 are moved to the opposite side. When the pressing plate 206 is pushed, the cylinder 207 on the surface of the pressing plate 206 leaves the inside of the two sliders 205, that is, the clamping of the two sliders 205 is released, and the two sliders 205 can be moved. When the two sliders 205 cannot continue to slide, the end faces of the sliders 205 are not against the end faces of the sound absorbing plate 101, and then the sound absorbing plate 101 can be replaced. While pulling the hand-pulling plate 110 to one side, the sound absorbing plate 101 is held and moved, so that the L-shaped block 102 on the surface of the sound absorbing plate 101 leaves the L-shaped hole 103 of the other sound absorbing plate 101, so that the sound absorbing plate 101 is removed, and then the lower end of the new sound absorbing plate 101 is pushed into the I-shaped groove 202.
