Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a connector for bellows based on an inner support structure in a slot. Background Technique

[0002] A bellows refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. The bellows mainly consists of a bellows body, a connecting pipe and other connecting components. The bellows body is the core part, and its pipe wall presents a corrugated structure. These corrugations can have different shapes, such as U-shaped, C-shaped, etc. The connecting pipe is used to connect the bellows with other pipes or devices, so that fluids can flow in and out of the bellows smoothly. When the bellows is subjected to axial pressure or tension, its corrugated part will contract or expand accordingly. For example, in a hydraulic system, when the liquid pressure acts on one side of the bellows, the bellows will produce corresponding deformations according to the magnitude of the pressure. This deformation characteristic enables the bellows to be used for various functions such as pressure measurement and displacement compensation.

[0003] A bellows connector is a component used to connect bellows, and it plays a crucial role in the bellows system.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides a technical solution: a connector for a corrugated pipe based on an inner support structure of a slot, including a first connecting block 1, a second connecting block 2, a positioning insertion block 3, an inner baffle 4, an outer baffle 5, a first positioning slot 6, an unlocking pressure plate 7, a positioning slider 8, a positioning locking block 9, an auxiliary slot 10, a first piston column 11, a second piston column 12, an auxiliary locking block 13, a limit groove 14 and a sealing airbag 15. On the side of the first connecting block 1, a second connecting block 2 is provided. A positioning insertion block 3 is fixed on the side surface of the first connecting block 1. An inner baffle 4 and an outer baffle 5 are fixed on the side surface of the second connecting block 2. The width of the positioning insertion block 3 is greater than the width of the inner baffle 4, and the width of the positioning insertion block 3 is less than the width of the outer baffle 5. When using this device, first dock the first connecting block 1 and the second connecting block 2, so that the positioning insertion block 3 is inserted into the grooves of the inner baffle 4 and the outer baffle 5, so that the positioning locking block 9 is pushed by the spring on the surface and snapped into the first positioning slot 6, thereby connecting the positioning insertion block 3, the inner baffle 4 and the outer baffle 5. The positioning insertion block 3 is limited bidirectionally by the inner baffle 4 and the outer baffle 5, increasing the stability of the installation and connection of the first connecting block 1 and the second connecting block 2.

[0031] A first positioning slot 6 is opened on the inner surface of the outer baffle 5. An unlocking pressure plate 7 is slidably connected to the inner wall of the first positioning slot 6. A positioning slider 8 is fixedly connected to the outer surface of the unlocking pressure plate 7. The unlocking pressure plate 7 is designed in a long strip shape. A spring is connected between the positioning slider 8 and the outer baffle 5. A spring is connected between the positioning locking block 9 and the positioning insertion block 3, and the positioning locking block 9 and the first positioning slot 6 form a snap connection. When it is necessary to separate the first connecting block 1 and the second connecting block 2, by pressing the positioning slider 8, the positioning slider 8 drives the unlocking pressure plate 7 to squeeze the positioning locking block 9, so that the positioning locking block 9 slides out of the first positioning slot 6, facilitating the extraction and disassembly of the positioning insertion block 3.

[0032] A positioning block 3 is slidably connected to the surface facing the outer baffle 5 with a positioning latch 9. The auxiliary sealing mechanism includes an auxiliary slot 10 which is opened inside the positioning block 3. A first piston rod 11 is slidably connected to the inner wall of the cavity of the auxiliary slot 10. Second piston rods 12 are slidably connected to both the top surface and the bottom surface of the cavity of the auxiliary slot 10. One end of the second piston rod 12 is fixedly connected to an auxiliary latch 13. Limiting slots 14 are opened on the surfaces of the inner baffle 4 and the outer baffle 5 facing the positioning block 3. A sealing airbag 15 is fixedly connected to the outer surface of the auxiliary latch 13. When the positioning block 3, the inner baffle 4 and the outer baffle 5 are inserted, the first piston rod 11 on the side surface of the positioning block 3 is pushed by the surface of the second connecting block 2, so that the first piston rod 11 guides air to the second piston rod 12, and the air is filled into the sealing airbag 15 through the opening on the surface of the second piston rod 12, facilitating the sealing airbag 15 to expand and snap into the annular groove on the inner wall of the limiting slot 14.

[0033] An auxiliary sealing mechanism is arranged inside the positioning block 3. By opening the auxiliary slot 10 inside the positioning block 3, the first piston rod 11 drives the second piston rod 12 and the auxiliary latch 13 to move and perform fitting and sealing through the sealing airbag 15. The horizontal cross-section of the auxiliary slot 10 is of a T-shaped design, and the side surface of the auxiliary slot 10 is penetrated by the first piston rod 11. A spring is connected between the first piston rod 11 and the auxiliary slot 10. A spring is connected between the second piston rod 12 and the auxiliary slot 10. The auxiliary latch 13 and the limiting slot 14 form a snap connection. An annular groove is arranged on the inner wall of the limiting slot 14. The second piston rod 12 is communicated with the cavity of the sealing airbag 15. The sealing airbag 15 is of an annular design. When the sealing airbag 15 is filled with air, the air will continue to push the second piston rod 12 and the auxiliary latch 13 to move, so that the auxiliary latch 13 snaps into the limiting slot 14, which is beneficial for auxiliary positioning and increases the connection stability of the device. Moreover, the auxiliary latch 13 presses the sealing airbag 15, so that the sealing airbag 15 fits the surfaces of the positioning block 3, the inner baffle 4 and the outer baffle 5, thereby supporting the positioning block 3, the inner baffle 4 and the outer baffle 5 to ensure stability, and further improving the sealing performance of the device and increasing the practicability.

[0034] Working principle: When using the connector for corrugated pipes with an inner slot support structure, first insert the positioning plug 3 into the grooves of the inner baffle 4 and the outer baffle 5, and engage and connect with the first positioning slot 6 through the positioning block 9, so as to fix the first connecting block 1 and the second connecting block 2. By pressing the positioning slider 8 to drive the unlocking pressing plate 7 to squeeze the positioning block 9 for unlocking. After the first piston rod 11 is pushed by the surface of the second connecting block 2, the first piston rod 11 introduces air into the opening on the surface of the second piston rod 12, causing the sealing airbag 15 to be inflated. Subsequently, the air pushes the second piston rod 12 and the auxiliary locking block 13 to engage with the limiting slot 14, and the sealing airbag 15 will fit and support the positioning plug 3, the inner baffle 4 and the outer baffle 5 for sealing, increasing the overall practicability.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
