Description

Technical Field

[0001] The utility model relates to the technical field of open bellows, in particular to an open bellows with a clamping joint. Background Art

[0002] A corrugated pipe is a pipe with a regular wave shape. Commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum, etc. They are mainly used for non-concentric axial transmission or irregular turning, expansion and contraction with a very small bending radius, or to absorb thermal deformation of the pipe. They are often used in situations where fixed elbows are installed to connect pipes to pipes and pipes to equipment.

[0003] In the process of connecting the existing corrugated pipes, two corrugated pipes need to be overlapped and fixed with a clamp.

[0004] However, the existing bellows are not convenient for tight plug-in fitting during connection, resulting in unstable connection and easy detachment, which affects the use. Using a bellows with a card connector for connection can make the two quickly and tightly fixed, so a new solution is needed to solve this problem. Utility Model Content

[0007] Furthermore, the outer surface of each of the first clamping joints is fixedly connected with a triangular ring plate, the outer surface of each of the second clamping joints is fixedly connected with an elastic hook plate, and the outer surface of each of the elastic hook plates is clamped with the corresponding triangular ring plate.

[0008] Furthermore, a waterproof pad is provided inside each of the bellows bodies, and an outer surface of each of the waterproof pads is slidably connected to the corresponding second clamping joint.

[0009] Furthermore, a fixing groove is formed on the outer surface of each of the second card connectors, two fixing cards are inserted into the inner wall of each of the fixing grooves, and the other end of each of the fixing cards is connected to the corresponding first card connector.

[0010] Furthermore, a placement groove is provided on the outer surface of each of the fixed card plates, and a slot is provided on one end of each of the fixed card plates that is away from each other.

[0011] Furthermore, a plurality of U-shaped frames are provided on the outside of each bellows body, the outer surface of each U-shaped frame is slidably connected to the corresponding placement groove, and a placement box is fixedly connected to one side of each U-shaped frame away from the corresponding bellows body.

[0012] Furthermore, the inner wall of each placement box is slidably connected with an insertion rod, the outer surface of each insertion rod is plugged into the corresponding slot, the outer surface of each insertion rod is sleeved with a spring, and one end of each spring close to the corresponding U-shaped frame is fixedly connected to the corresponding insertion rod, and the other end is fixedly connected to the corresponding placement box.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a first clamping joint, a second clamping joint, a first clamping block, a second clamping block, a clamping groove, a sliding groove, a triangular ring plate, an elastic hook plate and other components. By inserting the first clamping joint into the corresponding second clamping joint, the second clamping block will slide into the sliding groove of another second clamping joint until the first clamping block is clamped with the corresponding clamping groove. During this process, the elastic hook plate will be squeezed with the corresponding triangular ring plate, and the two corrugated pipes will be installed and fixed by the clamping of the elastic hook plate and the corresponding triangular ring plate, thereby achieving the effect that the device can quickly install the corrugated pipe by the clamping of the elastic hook plate and the triangular ring plate.

[0015] 2. The utility model sets a fixed card plate, a placement groove, a slot, a U-shaped frame, a placement box, an insertion rod, a spring and other components, and fixes the two corrugated tubes by plugging the fixed card plate. At this time, the U-shaped frame is slid into the corresponding placement groove. Before this, the insertion rod is pulled. At this time, the insertion rod will drive the corresponding spring to compress it until the insertion rod and the corresponding slot are on the same central axis. At this time, the insertion rod is released, and the spring will push the corresponding insertion rod into the corresponding slot under the action of its rebound force, thereby achieving the effect that the device can quickly fix the U-shaped frame by plugging the insertion rod into the corresponding slot.
