Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a detachable bellows. Background Art

[0002] Bellows can be categorized as either expandable or inflexible. Inflexible bellows are primarily used in applications where a fixed length and shape must be maintained. They may be made of metal, plastic, or other materials, but are not designed to expand or contract. These bellows are typically used to protect wires, cables, or other pipes from mechanical damage or environmental influences. Inflexible bellows are widely used in areas such as circuit wiring, automotive manufacturing, construction, and mechanical equipment.

[0003] At present, in order to ensure that the entire pipeline can be stably assembled and installed, it is usually necessary to splice and combine multiple independent corrugated pipes together to form a complete pipeline structure. The existing multiple corrugated pipes are mostly connected by hot melt or electric melt. Although the two corrugated pipes can be installed and fixed, the two corrugated pipes cannot be disassembled after installation, which is not convenient for later replacement and maintenance. Therefore, a detachable corrugated pipe is now proposed. Utility Model Content

The outer wall of the first bellows 1 is provided with first arc-shaped protective plates 6 distributed equidistantly around the circumference, and the outer wall of the second bellows 2 is provided with second arc-shaped protective plates 7 distributed equidistantly around the circumference.

[0021] Furthermore, a sealing ring is provided between one of the first mounting rings 3 and one of the second mounting rings 4 .

[0022] It should be noted that the sealing ring is made of rubber and is elastic. A first ring-shaped mounting groove is provided on one side of the first mounting ring 3, and a second ring-shaped mounting groove is provided on one side of the second mounting ring 4. During installation, the sealing ring is placed between the first mounting groove and the second mounting groove. The sealing ring will be inserted into the inside of the first mounting groove and the second mounting groove, and the first mounting groove and the second mounting groove will form a sealing groove for installing the sealing ring. The thickness of the sealing ring is greater than the thickness of the sealing groove by 2 mm. In this way, when the first mounting ring 3 and the second mounting ring 4 are attached together, the sealing ring will be pressed against the inner wall of the sealing groove, thereby achieving a better sealing effect.

[0023] Furthermore, the outer wall of the first mounting ring 3 is provided with first mounting holes 8 distributed equidistantly around the circumference, and the outer wall of the second mounting ring 4 is provided with second mounting holes 9 distributed equidistantly around the circumference.

At the same time, the first bellows 1 and the second bellows 2 can also be disassembled, thereby facilitating later replacement and maintenance.

[0025] Furthermore, the inner wall of the first arc-shaped protective plate 6 is in contact with the outer wall of the first corrugated tube 1 , and the inner wall of the second arc-shaped protective plate 7 is in contact with the outer wall of the second corrugated tube 2 .

[0026] It should be noted that the first arc-shaped protective plate 6 and the second arc-shaped protective plate 7 are both arranged in an arc shape, which can be attached to the outer walls of the first corrugated tube 1 and the second corrugated tube 2, and can form a good reinforcement effect on the first corrugated tube 1 and the second corrugated tube 2, and can prevent the longer first corrugated tube 1 and the second corrugated tube 2 from bending.

[0027] Furthermore, both ends of the first arc-shaped protective plate 6 are fixedly connected with a first connecting plate 11, a first connecting hole 12 is provided on the first connecting plate 11, the mounting bolt 5 passes through the first connecting hole 12, the first connecting plate 11 is attached to the first mounting ring 3, and both ends of the second arc-shaped protective plate 7 are fixedly connected with a second connecting plate 13, a second connecting hole 14 is provided on the second connecting plate 13, the mounting bolt 5 passes through the second connecting hole 14, and the second connecting plate 13 is attached to the second mounting ring 4.

[0028] It should be noted that by attaching multiple first arc-shaped protective plates 6 to the outer wall of the first corrugated tube 1, and then attaching multiple second arc-shaped protective plates 7 to the outer wall of the second corrugated tube 2, and passing the mounting bolts 5 through the connecting holes on the connecting plate, multiple first arc-shaped protective plates 6 can be installed on the outer wall of the first corrugated tube 1, and multiple second arc-shaped protective plates 7 can also be installed on the outer wall of the second corrugated tube 2.

[0029] The working principle of the utility model is as follows: the first mounting ring 3 at one end of the first bellows 1 and the second mounting ring 4 at one end of the second bellows 2 are attached together, and then the mounting bolt 5 is inserted into the first mounting hole 8 and the second mounting hole 9, and the mounting nut 10 is screwed on the mounting bolt 5, so that the installation and fixation of the first bellows 1 and the second bellows 2 can be completed. At the same time, the first bellows 1 and the second bellows 2 can also be disassembled, which is convenient for later replacement and maintenance. Multiple first arc-shaped protective plates 6 are attached to the outer wall of the first bellows 1, and then multiple second arc-shaped protective plates 7 are attached to the outer wall of the second bellows 2, and the mounting bolts 5 are passed through the connecting holes on the connecting plate. Multiple first arc-shaped protective plates 6 can be installed on the outer wall of the first bellows 1, and multiple second arc-shaped protective plates 7 can also be installed on the outer wall of the second bellows 2. Through multiple first arc-shaped protective plates 6 and multiple second arc-shaped protective plates 7, the first bellows 1 and the second bellows 2 can be reinforced, which can prevent the longer first bellows 1 and the second bellows 2 from bending.
