Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a bellows with leak-proof interfaces. Background Art

[0002] In fluid transmission systems, bellows, as an important connecting element, are widely used due to their good flexibility, corrosion resistance and relatively low cost. They are usually widely used in gas, water supply and drainage, chemical industry, machinery and other fields.

[0003] However, during the use of the bellows, docking operations are usually required. Most of the current docking structures are docked and locked by means of threads. After long-term use, due to the deformation characteristics of the bellows, it is easy to be affected by the external environment and produce vibrations, which will cause the nut to loosen, resulting in leakage. Usually, the human eye cannot intuitively observe the looseness of the nut, and it is generally necessary to frequently use tools for tightening operations, which brings more inconvenience to use. For this reason, the applicant proposes a bellows with a leak-proof interface to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a bellows with leak-proof interface to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bellows with leak-proof interface, comprising a bellows body and a docking mechanism assembled at one end of the bellows body, and a locking mechanism assembled at the other end of the bellows body;

[0006] The docking mechanism comprises a docking joint connected to one end of the bellows body, a rotating sleeve is rotatably mounted on the outer side of the docking joint, a first indicator needle is fixedly mounted on the top of the rotating sleeve, and a sealing groove is opened at one end of the docking joint;

[0007] The locking mechanism includes a butt joint tube connected to the other end of the bellows body, one side of the butt joint tube is connected to a sealing head extending into the butt joint, one side of the butt joint tube and located on the outside of the sealing head is clamped with a corrugated rubber ring extending into the sealing groove, a locking cap is rotatably installed on the outside of the butt joint tube, and a second indicator needle corresponding to the first indicator needle is fixedly installed on one side of the locking cap.

[0008] Preferably, the rotating sleeve and the docking head are fixed by a fixing bolt, and a sealing gasket corresponding to the locking cap is fixedly mounted on one side of the rotating sleeve.

[0009] Preferably, the docking head and the locking cap are installed via a spiral thread, and the inner wall of the locking cap is provided with a spiral groove used in conjunction with the spiral thread.

[0010] Preferably, a silicone ring is clamped on the outer side of the sealing head, and the silicone ring is fitted with the inner wall of the docking head.

[0011] Preferably, a limiting disk used in conjunction with a locking cap is fixedly mounted on the outer side of the butt joint tube, and a sealing ring is fixedly connected to one side of the limiting disk.

[0012] Preferably, the corrugated rubber ring is mounted on the butt-jointed pipe by a clamping block, and a clamping groove for use with the clamping block is provided on one side of the corrugated rubber ring.

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

[0014] The leak-proof bellows of the interface can lock the butt joint and the butt joint by using the locking cap, so that the first indicator needle can be aligned with the second indicator needle by rotating the rotating sleeve. When the locking cap is loose, the second indicator needle can be offset from the first indicator needle, so that the naked eye can more intuitively find that the locking cap is loose, which is convenient for timely tightening. When the second indicator needle is not offset from the first indicator needle, it means that the locking cap is not loose and there is no need to tighten, which brings more convenience to maintenance work. At the same time, the corrugated rubber ring is inserted into the sealing groove, so that the butt joint and the butt joint can be sealed conveniently. Even if the locking cap is loose, the corrugated rubber ring can be displaced a certain distance in the sealing groove, and leakage can be avoided by the bulge on the surface of the corrugated rubber ring tightly fitting with the sealing groove, thereby effectively improving the leak-proof effect.

The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0023] See also Figure 1-5 As shown, a bellows with leak-proof interface proposed by the utility model comprises a bellows body 1 and a docking mechanism 2 assembled at one end of the bellows body 1, and a locking mechanism 3 assembled at the other end of the bellows body 1, wherein the docking mechanism 2 comprises a docking joint 201 connected to one end of the bellows body 1, a rotating sleeve 207 is rotatably mounted on the outer side of the docking joint 201, a first indicator needle 203 is fixedly mounted on the top of the rotating sleeve 207, a sealing groove 206 is opened at one end of the docking joint 201, and the locking mechanism 3 comprises a docking tube 301 connected to the other end of the bellows body 1, a sealing head 306 extending into the docking joint 201 is connected to one side of the docking tube 301, a corrugated rubber ring 305 extending into the sealing groove 206 is clamped on one side of the docking tube 301 and located on the outer side of the sealing head 306, a locking cap 308 is rotatably mounted on the outer side of the docking tube 301, and a second indicator needle 309 corresponding to the first indicator needle 203 is fixedly mounted on one side of the locking cap 308.

[0024] Based on the above-mentioned structural setting, the leak-proof bellows of the interface is composed of a bellows body 1, a docking mechanism 2 and a locking mechanism 3, wherein by docking the docking mechanism 2 with the locking mechanism 3, the docking mechanism 2 can be fixed and sealed by the locking mechanism 3, so that the docking operation of the multi-section bellows body 1 can be convenient. Specifically, in the working process, by inserting the sealing head 306 into the docking joint 201, the docking operation between the docking pipe 301 and the docking joint 201 can be conveniently performed, and the corrugated rubber ring 305 can be inserted into the sealing groove 206. The multiple protrusions on the surface of the corrugated rubber ring 305 can fit tightly with the inner wall of the sealing groove 206, thereby effectively improving the sealing effect between the docking pipe 301 and the docking joint 201. By rotating the locking cap 308, By threading the docking tube 301 with the docking joint 201, the docking tube 301 and the docking joint 201 can be locked and fixed. By rotating the rotating sleeve 207, the first indicator needle 203 is adjusted to be aligned with the second indicator needle 309. When the locking cap 308 is loose, the second indicator needle 309 can be offset from the first indicator needle 203, so that the naked eye can more intuitively find that the locking cap 308 is loose, which is convenient for timely tightening operations. When the second indicator needle 309 is not offset from the first indicator needle 203, it means that the locking cap 308 is not loose and there is no need to tighten. It is convenient for personnel to judge the looseness of the locking cap 308 by observing the offset difference between the first indicator needle 203 and the second indicator needle 309, which brings more convenience to maintenance work.

[0025] Furthermore, the rotating sleeve 207 is fixed to the docking joint 201 by a fixing bolt 202, and a sealing gasket 204 corresponding to the locking cap 308 is fixedly installed on one side of the rotating sleeve 207. The fixing bolt 202 can conveniently fix the adjusted rotating sleeve 207 to prevent the rotating sleeve 207 from accidentally rotating, and facilitate the positioning of the first indicator needle 203. When the locking cap 308 is threadedly connected to the docking joint 201, the locking cap 308 can be moved toward the rotating sleeve 207, so that the locking cap 308 can squeeze the sealing gasket 204. The sealing gasket 204 can conveniently seal the threaded opening of the locking cap 308, which can prevent external water stains and impurities from entering the threaded opening of the locking cap 308, and can avoid rust and corrosion, and can enhance the anti-leakage effect.

[0026] Furthermore, the butt joint 201 and the locking cap 308 are threadedly installed via the spiral pattern 205, and the inner wall of the locking cap 308 is provided with a spiral groove used in conjunction with the spiral pattern 205. The spiral pattern 205 enables the locking cap 308 to be conveniently threadedly locked with the butt joint 201.

[0027] Furthermore, a silicone ring 307 is clamped on the outer side of the sealing head 306, and the silicone ring 307 is in contact with the inner wall of the butt joint 201. When the sealing head 306 is inserted into the butt joint 201, the silicone ring 307 can be in contact with the inner wall of the butt joint 201, so that the sealing head 306 and the butt joint 201 can be easily sealed, so that the butt joint 201 and the butt joint 301 can maintain the medium flow without leakage.

[0028] Furthermore, a limiting plate 302 used in conjunction with the locking cap 308 is fixedly installed on the outer side of the butt joint 301, and a sealing ring 303 is fixedly connected to one side of the limiting plate 302. In the process of locking by the locking cap 308, the limiting plate 302 can be used to limit the locking cap 308, so that the locking cap 308 can drive the butt joint 301 and the butt joint 201 to be squeezed and locked. When the locking cap 308 contacts the limiting plate 302, the sealing ring 303 can be squeezed. The sealing ring 303 can conveniently seal the locking cap 308 and the limiting plate 302 to prevent external water stains and impurities from entering the locking cap 308.

[0029] Furthermore, the corrugated rubber ring 305 is connected to the butt joint 301 by a clamping block 304, and a clamping slot for use with the clamping block 304 is provided on one side of the corrugated rubber ring 305. The clamping block 304 can facilitate the installation of the corrugated rubber ring 305, so that the corrugated rubber ring 305 can be replaced and maintained, thereby improving the sealing effect.
