Description

Technical Field

[0001] The utility model relates to the technical field of air duct brackets, in particular to an oblique bracing type air duct bracket. Background Art

[0002] The air duct is a piping system used for air transportation and distribution. There are two types of air ducts: composite air ducts and inorganic air ducts. The air duct needs to be installed on the ceiling through an air duct bracket. The bracket is mainly fixed to the building floor or wall with expansion bolts, so that the air duct can be placed on the bracket later to achieve stable installation of the air duct.

[0003] After searching, the existing Chinese patent with publication number CN202222210730.7 discloses a diagonal brace air duct bracket. When facing air ducts of different diameters, the staff can control the movement of the moving block through a two-way threaded rod. The moving block can drive the installation frame and the clamping block to move, clamp and fix the air duct, thereby making it convenient to fix air ducts of different diameters.

[0004] The above technical solution has the following defects: although such an air duct bracket can adjust the clamping spacing of the bracket through a threaded rod so that the bracket can be suitable for air ducts of different diameters, during actual use, the gas circulation inside the air duct will cause the pipe wall to vibrate, and such a clamping structure is difficult to buffer and absorb the vibration of the air duct. In order to further improve the vibration reduction and protection ability of the air duct, a diagonal brace air duct bracket is proposed, which can not only stably clamp air ducts of different diameters and has good applicability, but also can provide vibration reduction protection for the positioned air duct, reduce the noise generated by vibration, and increase the service life.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a dust cover is fixedly connected to the gap between the connecting support plate and the load-bearing tray.

[0011] Furthermore, the L-shaped bracket is evenly provided with waist-shaped holes corresponding to the positioning bolts.

[0012] Furthermore, the mounting plate and the upper limiting frame are provided with through holes corresponding to the positioning bolts.

[0013] Furthermore, the rubber pads on both sides are configured as arc-shaped structures.
