DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a noise reduction and sound insulation cover, including an L-shaped bottom plate 1, a plurality of pulleys 2 are fixedly connected to the bottom of the L-shaped bottom plate 1, a sound insulation cover body 3 is fixedly connected to the top of the L-shaped bottom plate 1, a plurality of evenly distributed triangular covers 4 are fixedly connected to the front end of the sound insulation cover body 3, a fluorescent strip 5 is fixedly connected to the rear end of the sound insulation cover body 3, a counterweight box 6 is fixedly connected to the top of the L-shaped bottom plate 1, two auxiliary stabilizing mechanisms 7 are arranged at the bottom of the L-shaped bottom plate 1, a connecting block 8 is fixedly connected to one side of the L-shaped bottom plate 1, two clamping holes 9 are penetrated through the front and rear ends of the connecting block 8, a connecting groove 10 corresponding to the connecting block 8 is opened on the other side of the L-shaped bottom plate 1, and two clamping columns 11 are slidably connected to the rear end of the connecting groove 10, springs 12 are sleeved on the outer walls of the two clamping columns 11, and pull plates 13 are fixedly connected to the rear ends of the two clamping columns 11.

[0023] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the multiple pulleys 2 are all universal self-locking wheels, so that the pulleys 2 can slide and self-lock flexibly, which is convenient for the staff to move and position the L-shaped bottom plate 1 and the sound insulation cover body 3, and greatly reduces the labor intensity of the staff.

[0024] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the interior of the soundproof cover body 3 is filled with a glass fiber sound-absorbing layer. The glass fiber has good sound absorption performance, which further improves the noise reduction and sound insulation effect of the soundproof cover body 3.

[0025] Further as Figure 4 As shown, it is worth explaining in detail that the auxiliary stabilization mechanism 7 includes a threaded rod 701 rotatably connected to the inside of the L-shaped bottom plate 1, a rotating plate 702 is fixedly connected to the top of the threaded rod 701, a rotating seat 703 is installed at the bottom of the threaded rod 701, and a fixed suction cup 704 is fixedly connected to the bottom of the rotating seat 703. By setting the auxiliary stabilization mechanism 7, the rotating plate 702 drives the threaded rod 701 to rotate, so that the fixed suction cup 704 descends to further assist in stabilizing the device and prevent the sound insulation cover body 3 from tipping over in bad weather.

[0026] Further as Figure 4 As shown, it is worth explaining in detail that a thread groove corresponding to the threaded rod 701 is opened on the surface of the L-shaped bottom plate 1, and the thread groove cooperates with the threaded rod 701, so that the threaded rod 701 can be raised and lowered while rotating, thereby driving the fixed suction cup 704 to rise and fall.

[0027] According to the above working process, it can be known that: by setting the pulley 2, it is convenient for the staff to move the L-shaped bottom plate 1 and the sound insulation cover body 3, and at the same time, the counterweight box 6 and the auxiliary stabilization mechanism 7 cooperate. When moving to the specified position, a counterweight block is added to the counterweight box 6. By increasing the counterweight, the device remains stable. At the same time, the rotating plate 702 drives the threaded rod 701 to rotate, so that the fixed suction cup 704 descends to further assist in stabilizing the device and prevent the sound insulation cover from tipping over in bad weather.

[0028] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the outer wall of the connecting block 8 is tightly fitted with the inner wall of the connecting groove 10, and the outer wall of the clamping column 11 is tightly fitted with the inner wall of the clamping hole 9. By setting the clamping hole 9 and the clamping column 11, a detachable connection between the connecting block 8 and the connecting groove 10 is achieved, thereby facilitating the installation and disassembly between multiple L-shaped base plates 1.

[0029] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the spring 12 is fixedly connected between the rear end of the L-shaped base plate 1 and the front end of the pull plate 13. Under the action of the spring 12, the clamping column 11 can slide flexibly inside the connecting groove 11. The front end of the clamping column 11 is hemispherical in design. The hemispherical design makes it smoother for the clamping column 11 to be inserted into the clamping hole 9, which facilitates the assembly of the L-shaped base plate 1.

[0030] This solution has the following working process: in actual use, the device is moved to the specified position through the pulley 2, and then a counterweight block is added to the counterweight box 6. The device is kept stable by adding the counterweight. At the same time, the rotating plate 702 is rotated to drive the threaded rod 701 to rotate, so that the fixed suction cup 704 descends to further assist in stabilizing the device. The pull plate 13 is pulled backward, and the connecting block 8 is inserted into the connecting groove 10. Then the pull plate 13 is released, and the spring 12 drives the clamping column 11 to reset and insert it into the clamping hole 9, so as to realize the detachable connection between the connecting block 8 and the connecting groove 10, thereby facilitating the installation and disassembly between multiple L-shaped base plates 1, and the size of the sound insulation range can be flexibly adjusted according to actual use needs.

[0031] In summary: by setting the pulley 2, it is convenient for the staff to move the L-shaped base plate 1 and the sound insulation cover body 3. At the same time, the counterweight box 6 and the auxiliary stabilization mechanism 7 cooperate. When moving to the specified position, a counterweight block is added to the counterweight box 6. By increasing the counterweight, the device remains stable. At the same time, the rotating plate 702 drives the threaded rod 701 to rotate, so that the fixed suction cup 704 descends to further assist in stabilizing the device and prevent the sound insulation cover from tipping over in bad weather; by setting the clamping hole 9 and the clamping column 11, the detachable connection between the connecting block 8 and the connecting groove 10 is realized, which facilitates the installation and disassembly between multiple L-shaped base plates 1, and can flexibly adjust the size of the sound insulation range according to actual use needs.
