Novel tube glue quick change mechanism

Abstract

This utility model discloses a novel quick-change mechanism for PTFE tape, including a main cylinder, an insert cylinder, staggered ribs, a rubber sleeve, a rubber cone cover, a comb plate, an inner ring rib, and a U-shaped side handle. The insert cylinder is embedded inside the main cylinder. By setting up a quick-change mechanism for replacing and cleaning PTFE tape, the main cylinder of the quick-change mechanism, with the rubber cone cover, is fitted over the metal tube containing the PTFE tape. Then, silicone oil-soaked and hardened PTFE tape can be sprayed on. After the main cylinder is removed, the insert cylinder is inserted and then screwed onto the outside of the metal tube, so that the comb plate inside the insert cylinder combs and cleans the PTFE tape in the thread groove of the metal tube. This facilitates quick cleaning of the PTFE tape at the metal tube and ensures that the PTFE tape at the metal tube can be quickly cleaned and replaced. The oil-soaked PTFE tape effectively ensures that the PTFE tape at the metal tube can be cleaned quickly and with low damage, preventing damage to the threads when cleaning and replacing the PTFE tape at the metal tube.

Description

Technical Field

[0001] This utility model relates to the field of tubing replacement technology, and in particular to a novel quick-change mechanism for tubing. Background Technology

[0002] Pipe sealant is a sealing material used at pipe connections (such as threaded and flanged joints). It seals and prevents leaks by filling gaps in the joint and preventing media leakage. Common types, depending on their form and material, include: PTFE tape, liquid sealant, and lead-oil hemp fiber. Leaks such as water or air at pipe joints may indicate that the pipe sealant is aging and therefore needs to be replaced.

[0003] Currently, when replacing some aged tubing adhesive, the PTFE tape at the threaded connection of metal pipes often ages and hardens, thus clogging the pipe thread grooves. At this time, workers often need to manually scrape off the PTFE tape with a scraper. This scraping method requires high manual operation skills, is prone to fatigue, and is also prone to scratching the threads after manual operation errors, thus affecting the quick replacement of tubing adhesive. To address this, we propose a new quick-change mechanism for tubing adhesive. Utility Model Content

[0004] The main objective of this invention is to provide a novel quick-change mechanism for PTFE tape. This mechanism, designed for the replacement and cleaning of PTFE tape, involves a main sleeve with a rubber cone cover fitted over the metal tube containing the PTFE tape. The PTFE tape, hardened by silicone oil, is then sprayed onto the sleeve. After removal, a insert sleeve is inserted and screwed onto the metal tube. This allows a comb plate inside the insert sleeve to clean the PTFE tape within the threaded grooves of the metal tube. This facilitates quick and easy cleaning of the PTFE tape on the metal tube, ensuring rapid replacement. Furthermore, the oil molecules penetrate the hardened micro-cracks in the PTFE tape after soaking, reducing friction with the metal surface and ensuring rapid, low-damage cleaning. This prevents damage to the threads during PTFE tape replacement and effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel quick-change mechanism for tubing includes a main tube, an insert tube, staggered ribs, a rubber sleeve, a rubber cone cover, a comb plate, an inner ring rib, and a U-shaped side handle. The insert tube is embedded in the main tube, and staggered grooves for engaging the staggered ribs are formed on the inner wall of the main tube. The staggered ribs are fixed to the outer wall of the insert tube. A rubber sleeve is bonded to the lower opening of the main tube, and a rubber cone cover is integrally formed at the lower opening of the rubber sleeve. An inner ring rib protrudes from the inner conical surface of the rubber cone cover. A comb plate protrudes from the inner wall of the insert tube. A U-shaped side handle is welded to the outer wall of the main tube.

[0007] Furthermore, the two sets of long grooves and one set of short grooves of the staggered fixed grooves are distributed in a ring on the inner wall of the main tube, and the two sets of long ribs and one set of short ribs of the staggered fixed ribs are fixed in a ring on the outer wall of the insert tube.

[0008] By adopting the above technical solution, the insert can be clamped at multiple points in the staggered groove of the main tube by means of the ring-shaped distributed staggered ribs, ensuring the clamping stability of the insert and the main tube.

[0009] Furthermore, the surface of the rubber sleeve below the main tube is provided with an adhesive hole for mounting the inner connecting column, and the inner connecting column is integrally formed on the bottom of the main tube. The top of the rubber sleeve has a C-shaped sleeve edge that is bonded to the outer wall of the main tube.

[0010] By adopting the above technical solution, when bonding the main tube and the rubber sleeve, after applying glue to the bottom of the main tube, the inner connecting post is inserted into the adhesive hole of the rubber sleeve for internal connection. Then, the rubber sleeve and the C-shaped sleeve edge are used to bond the main tube a second time, ensuring the bonding strength between the rubber sleeve and the main tube.

[0011] Furthermore, the bottom opening of the rubber cone cover is provided with an upward-facing cross-shaped groove;

[0012] By adopting the above technical solution, after the bottom cover opening of the rubber cone cover is provided with a cross groove, the bottom cover opening of the rubber cone cover can be easily opened at the cross groove, so as to fit onto the metal pipe wrapped with PTFE tape.

[0013] Furthermore, the comb teeth are provided with two sets of protruding parts on the inner wall of the insert, and the head of the comb teeth is an acute-angled head.

[0014] By adopting the above technical solution, two sets of opposing comb plates can be set inside the insert according to the thread groove specifications of the metal tube, so that when the insert rotates outside the metal tube, the comb plates can abut into the thread groove of the metal tube to comb up the foamed and softened raw material tape.

[0015] Furthermore, a flat connecting plate protrudes from the cylinder wall near the U-shaped side handle of the main cylinder, and a U-shaped side handle is welded to the outside of the flat connecting plate of the main cylinder.

[0016] By adopting the above technical solution, the host tube is welded with a U-shaped side handle on a flat connecting plate, so that a person can hold the U-shaped side handle and the flat connecting plate to rotate the host tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a quick-change mechanism for replacing and cleaning PTFE tape-type tubing. The main sleeve of the quick-change mechanism, with a rubber cone cover, is fitted over the metal tube containing the PTFE tape. Then, silicone oil is sprayed onto the hardened PTFE tape. After the main sleeve is removed, an insert sleeve is inserted. The insert sleeve then rotates outwards onto the metal tube, allowing the comb plate inside the insert sleeve to comb and clean the PTFE tape within the threaded grooves of the metal tube. This facilitates quick cleaning of the PTFE tape at the metal tube, ensuring rapid replacement of the PTFE tape at the metal tube.

[0019] Furthermore, after the PTFE tape at the metal pipe is soaked, the oil molecules penetrate the micro-cracks in the hardened PTFE tape, weakening its friction with the metal surface. This ensures that the PTFE tape at the metal pipe can be cleaned quickly and with minimal damage, preventing damage to the threads when cleaning or replacing the PTFE tape on the metal pipe.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-5 As shown, a novel quick-change tube adhesive mechanism includes a main tube 1, an insert tube 2, staggered ribs 4, a rubber sleeve 5, a rubber cone cover 6, a comb plate 7, an inner ring rib 8, and a U-shaped side handle 11. The insert tube 2 is embedded in the inner tube of the main tube 1, and staggered grooves 3 for mounting the staggered ribs 4 are formed on the inner wall of the main tube 1. The staggered ribs 4 are fixed to the outer wall of the insert tube 2 in a staggered manner. A rubber sleeve 5 is bonded to the lower opening of the main tube 1, and a rubber cone cover 6 is integrally formed at the lower opening of the rubber sleeve 5. The inner cone surface of the rubber cone cover 6 has a raised inner ring rib 8. A comb plate 7 is raised on the inner wall of the insert tube 2. A U-shaped side handle 11 is welded to the outer wall of the main tube 1.

[0028] Among them, the two sets of long grooves and one set of short grooves of the staggered fixed groove 3 are distributed in a ring on the inner wall of the main cylinder 1, and the two sets of long ribs and one set of short ribs of the staggered fixed rib 4 are fixed in a ring on the outer wall of the embedded cylinder 2.

[0029] By adopting the above technical solution, the insert 2 can be clamped at multiple points in the staggered groove 3 of the main tube 1 by means of the ring-shaped staggered fixed ribs 4, so as to ensure the clamping stability of the insert 2 and the main tube 1.

[0030] Among them, the surface of the rubber sleeve 5 below the main tube 1 is provided with an embedding hole 10 for mounting the inner connecting post 9, and the inner connecting post 9 is integrally formed on the bottom of the main tube 1. The top of the sleeve of the rubber sleeve 5 has a C-shaped sleeve edge that is bonded to the outer wall of the main tube 1.

[0031] By adopting the above technical solution, when the main tube 1 and the rubber sleeve 5 are bonded, after applying glue to the bottom of the main tube 1, the inner connecting post 9 is inserted into the embedding hole 10 of the rubber sleeve 5 for internal connection. Then, the rubber sleeve 5 is bonded to the main tube 1 again with the C-shaped sleeve edge to ensure the bonding strength between the rubber sleeve 5 and the main tube 1.

[0032] The bottom opening of the rubber cone cover 6 is provided with a cross-shaped groove 12 facing upwards;

[0033] By adopting the above technical solution, after the bottom cover opening of the rubber cone cover 6 is provided with a cross groove 12, the bottom cover opening of the rubber cone cover 6 can be easily opened at the cross groove 12, so as to fit onto the metal pipe wrapped with raw material tape.

[0034] Among them, the comb plate 7 is provided with two sets of protrusions on the inner wall of the insert 2, and the head of the comb plate 7 is an acute-angled head;

[0035] By adopting the above technical solution, two sets of opposing comb plates 7 can be set inside the insert 2 according to the specifications of the thread groove of the metal tube, so that when the insert 2 rotates outside the metal tube, the comb plates 7 can be inserted into the thread groove of the metal tube to comb up the foamed and softened raw material tape.

[0036] The main cylinder 1 has a flat connecting plate protruding from the cylinder wall near the U-shaped side handle 11, and the U-shaped side handle 11 is welded to the outside of the flat connecting plate of the main cylinder 1.

[0037] By adopting the above technical solution, the host cylinder 1 is welded with a U-shaped side handle 11 by a flat connecting plate, so that a person can hold the U-shaped side handle 11 and the flat connecting plate to rotate the host cylinder 1.

[0038] It should be noted that this utility model is a novel quick-change mechanism for tubing. When the PTFE tape hardens and is difficult to remove after disassembling the metal tube connection, silicone oil can be applied to the surface of the PTFE tape. Then, the main sleeve 1 is placed over the metal tube with the PTFE tape wrapped around it, so that the rubber cone 6 is placed upwards on the metal tube. The bottom opening of the rubber cone 6 is opened at the cross groove 12. Then, the rubber cone 6, together with the inner ring rib 8, is placed on the metal tube where the PTFE tape is located. The inner ring rib 8 is fitted over the outside of the metal tube as a stop position. Then, silicone oil can be added from the main sleeve 1 between the rubber cone 6 and the PTFE tape for soaking. After soaking for several minutes, the oil molecules penetrate the micro-cracks of the hardened PTFE tape, weakening its friction with the metal surface. Then, the main sleeve 1 and the rubber cone 6 are removed. A container can be used to collect the fallen silicone oil, and then the device is re-inserted. The cylinder 2 is secured inside the main cylinder 1 with staggered grooves 3 by means of staggered ribs 4. Then, the insert cylinder 2 is rotated outwards towards the metal pipe. The comb plate 7 inside the insert cylinder 2 can be screwed in along the threaded groove of the metal pipe without PTFE tape. Then, the main cylinder 1 is rotated by pinching the U-shaped side handle 11 and the flat connecting plate, so that the main cylinder 1 rotates with the insert cylinder 2. The comb plate 7 rotates clockwise upwards along the threaded groove of the metal pipe. When the sharp-angled head of the comb plate 7 touches the hardened PTFE tape, the PTFE tape is scooped up by the comb plate 7 and falls between the insert cylinder 2 and the metal pipe. As the comb plate 7 passes through the threaded groove of the metal pipe, the PTFE tape at the metal pipe can be scooped off. Then, the main cylinder 1 is rotated counterclockwise to screw the insert cylinder 2 away from the metal pipe. Then, the PTFE tape inside the insert cylinder 2 is cleaned. Afterwards, the metal pipe can be wiped clean, and the PTFE tape can be rewound and the metal pipe reconnected.
