Description

Technical Field

[0001] The utility model relates to the technical field of green buildings, in particular to a noise reduction and sound insulation device for green building construction. Background Art

[0002] Construction site noise mainly comes from construction machinery, equipment, vehicles, etc., as well as the activities of construction workers and the environment of the construction site. The sounds produced by these noise sources are often high in decibels, which will have adverse effects on the lives, work and health of surrounding residents. Therefore, it is very necessary to control and reduce the noise of urban construction sites.

[0003] Announcement No. "CN218323272U" provides a green building construction noise reduction and sound insulation device, which includes a plate body with an operating cavity inside and a splicing plate rotatably installed on one side of the plate body. The plate body is provided with a splicing mechanism for splicing; the splicing mechanism includes a splicing gear hinged inside the plate body, and the splicing gear is provided with a splicing rod. This patented technology can rotate the splicing rod out of the plate body by rotating the turntable, and then slide the splicing rod into the splicing cavity, and complete the splicing between the plate bodies by the engagement between the limit block 1 and the limit block 2. This installation method only requires two steps to complete the assembly of the plate body, thereby avoiding the cumbersome steps of rotating the connecting bolts in sequence in the existing installation method, greatly improving the installation efficiency.

[0004] However, the above device still has the following problems during implementation:

[0005] For example, this patented technology uses a spring-clipped plug-in method to complete the splicing between panels. Although the installation is quick and does not require the use of connecting bolts, it also makes it impossible to use bolts to fasten the panels together, making it easy for gaps to appear at the joints between the panels, which in turn affects the overall noise reduction and sound insulation effect and fails to achieve the desired effect.

[0031] Embodiment 2:

[0032] On the basis of the above embodiment, the outer wall of the rotating rod 305 is provided with an auxiliary component 11. Further, the auxiliary component 11 includes a connecting plate 1101, and the interior of the connecting plate 1101 is rotatably connected to the outer wall of the rotating rod 305. A connecting strip 1102 is fixedly connected to one side wall of the connecting plate 1101 at an equal distance. A side wall where two connecting strips 1102 are close to each other fits with the two side walls of the block 302. An extension block 1103 is fixedly connected to the two side walls of the block 302, and the bottom of the extension block 1103 fits with the top of the connecting strip 1102.

[0033] In this embodiment, when disassembly is required, the handle 312 can be pulled up to drive the rotating rod 305 to rise, so that the ratchet teeth 307 and the stop block 309 are separated and the restriction is released. At this time, the handle 312 can be rotated to drive the cam 306 to return to the original position. At this time, under the elastic force of the third spring 314, the connecting frame 301 automatically returns to its original position.

[0034] During this process, the inner part of the connecting plate 1101 is rotatably connected to the outer wall of the rotating rod 305, and a side wall of the connecting plate 1101 is fixedly connected with a connecting strip 1102 at an equal distance, and a side wall of the two connecting strips 1102 close to each other fits with the two side walls of the block 302, and at the same time, the two side walls of the block 302 are correspondingly fixedly connected with an extension block 1103, and the bottom of the extension block 1103 fits with the top of the connecting strip 1102, so that when the rotating rod 305 rises, the connecting plate 1101 can be synchronously driven to rise, and then the block 302 can be driven to rise through the connecting strip 1102 and the extension block 1103, so that the block 302 is pulled out of the connecting groove 7, and the quick disassembly is completed;

[0035] As described above, during the disassembly process, the handle 312 can be pulled upward to drive the block 309 to separate from the ratchet teeth 307, thereby releasing the squeezing of the rubber pad 4. During the pulling process, the connecting plate 1101 and the extension block 1103 cooperate to simultaneously pull the block 302 out of the connecting groove 7 to complete the quick disassembly, thereby ensuring the disassembly efficiency of the device.

[0036] Working principle: First, the connection block 6 on one side of the mounting plate 5 is inserted into the inner wall of the connecting frame 301 from the second slot 10 and the first slot 9 in sequence. When moving a certain distance, the end of the connection block 6 contacts the clamping block 302 and squeezes the inclined surface, so that the clamping block 302 rises and can be clamped into the connecting groove 7 by the elastic force of the first spring 304, thereby completing the quick plug-in of the two sound insulation board bodies 1;

[0037] Then, the gripping rod 312 is held to drive the rotating rod 305 to rotate, thereby driving the cam 306 to rotate, and the convex surface of the cam 306 presses the connecting frame 301, so that the connecting frame 301 moves away from the connecting block 6, so that the two sound insulation board bodies 1 press the rubber pad 4 therebetween to fill the gap at the connection, and the ratchet teeth 307 are pressed by the abutment block 309 to prevent the cam 306 from rotating, so that the rotating rod 305 can only rotate in one direction to avoid automatic loosening;

[0038] When disassembly is required, the handle bar 312 can be pulled up to drive the rotating rod 305 to rise, so that the ratchet teeth 307 and the stop block 309 are separated and the restriction is released. At this time, the handle bar 312 can be rotated to drive the cam 306 to return to the center. At this time, under the elastic force of the third spring 314, the connecting frame 301 is automatically reset. At the same time, when the rotating rod 305 rises, it can synchronously drive the connecting plate 1101 to rise, and then the card block 302 can be driven to rise through the connecting strip 1102 and the extension block 1103, so that the card block 302 is pulled out of the connecting groove 7 to complete the quick disassembly.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
