Description

Technical Field

[0001] This application relates to the field of pipeline technology, specifically to a rubber corrugated pipe resistant to negative pressure flattening. Background Technology

[0002] Rubber corrugated pipes have good elasticity and wear resistance, but it is also because of their good elasticity that their application range is limited. Under normal pressure, rubber corrugated pipes can play a normal role in connecting pipes.

[0003] However, when existing rubber bellows are under negative pressure, the negative pressure causes the rubber bellows to be flattened, its internal space to be compressed, its flow capacity to be greatly reduced, and even blockage may occur, resulting in poor applicability. Utility Model Content

[0004] The purpose of this application is to provide a rubber corrugated pipe that resists negative pressure flattening, thus solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a rubber corrugated tube resistant to negative pressure flattening, comprising a corrugated tube body. A plurality of support rings are uniformly and equidistantly fixedly connected to the inner wall of the corrugated tube body. A plurality of fixing plates are uniformly and equidistantly fixedly connected in a ring shape to the inner wall of each support ring. A plurality of fixing sleeves are disposed between two adjacent support rings. A transmission rod is hinged to one side wall of each fixing plate, and the other end of the transmission rod is hinged to a corresponding fixing sleeve. Two connecting rods are symmetrically and slidably connected within each fixing sleeve, and the other end of each connecting rod is slidably connected to a corresponding fixing plate.

[0007] By adopting the above technical solution, when the bellows body is under negative pressure, the bellows body will contract, and the adjacent support rings will move closer to each other. At this time, the fixed plates will move in opposite directions. The movement of the fixed plates will apply a force to the fixed sleeve through the transmission rod. The fixed sleeve will move on the corresponding fixed plate under the force. When the fixed sleeve contacts the inner wall of the bellows body, the fixed sleeve will support the bellows body and prevent the bellows body from denting. Through the above structure, the inside of the bellows body can be supported, and the denting of the bellows body under negative pressure can be prevented, thereby improving its applicability.

[0008] Optionally, a sliding groove is provided on one side wall of the fixing plate, and a sliding block is slidably connected in the sliding groove. One end of the sliding block passes through the opening of the sliding groove and extends outward and is fixedly connected to the corresponding connecting rod.

[0009] By adopting the above technical solution, the fixed sleeve is limited by the sliding block, so that the fixed sleeve can move on the fixed plate.

[0010] Optionally, a limiting rod is fixedly connected to the inner wall of the sliding groove, the limiting rod passing through the sliding block, and the sliding block being slidably connected to the limiting rod.

[0011] By adopting the above technical solution, the sliding block is prevented from detaching from the sliding groove.

[0012] Optionally, a rolling groove is provided on one side wall of the sliding block, and a rolling ball is provided in the rolling groove. The rolling ball passes through the opening of the rolling groove and is tumbling and connected to the bottom of the sliding groove.

[0013] By adopting the above technical solution, the friction between the sliding block and the sliding groove is reduced.

[0014] Optionally, the fixing sleeve is provided with two rubber bands, and the two ends of the rubber bands are respectively connected to two corresponding connecting rods.

[0015] By adopting the above technical solution, the connecting rod is prevented from falling off the fixed sleeve.

[0016] Optionally, four fixing plates are provided, and the four fixing plates are evenly distributed in a ring.

[0017] By adopting the above technical solution, the interior of the corrugated pipe body is fully supported.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application can support the inside of the bellows body by setting up a structure such as a bellows body, a support ring, a fixing plate, a fixing sleeve, a connecting rod and a sliding block, which can prevent the bellows body from sinking under negative pressure, thereby improving its applicability.
