Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe fitting technology, specifically a hydraulic pipe fitting sleeve. Background Technology

[0002] With the rapid development of society and economy, hydraulic pipe fittings are components in hydraulic systems that connect high-pressure oil pipes. Hydraulic pipe fittings can be further categorized into hydraulic hoses, high-pressure ball valves, quick couplings, compression fittings, welded fittings, high-pressure hoses, transition fittings, tee fittings, non-standard fittings, flared fittings, right-angle fittings, rotary fittings, quick couplings, stainless steel fittings, and copper fittings. Compression fittings are sealing pipe fittings suitable for non-corrosive or corrosive media such as oil, water, and gas, and are used with... Aluminum-plastic composite pipes offer flexible specifications and, when connected to pipelines, provide reliable connections and excellent sealing performance. Therefore, they are widely used in systems such as oil refining, chemical, light industry, textile, defense, metallurgy, aviation, and shipbuilding. They are also suitable for hydraulic transmission pipelines in various mechanical engineering and machine tool equipment. However, existing hydraulic pipe fittings typically use threaded tightening with a sealing ring, but threaded fixing requires drilling holes, which can lead to leakage at any threaded hole location, posing a problem. Therefore, a new hydraulic pipe fitting is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A hydraulic pipe fitting sleeve includes a fitting mechanism, a reinforcing mechanism, and a pipe mechanism. The fitting mechanism includes a fitting body, inner tubes disposed at both ends of the fitting body, a sealing sleeve fixedly fitted onto the end of the inner tube, a toothed ring fixedly installed on the inner end of the fitting body and surrounding the outer side of the sealing sleeve, and a sliding groove formed in the middle of the outer side of the sealing sleeve. The reinforcing mechanism includes a rotating ring slidably fitted onto the middle of the inner tube and located inside the sealing sleeve, a magnet clamped onto the surface of the rotating ring, a screw slidably connected to a protrusion on the inner side of the rotating ring, a gear threadedly connected to the middle of the screw, and a top plate fixedly connected to the top of the screw. A rectangular rod is slidably connected to the middle of the screw, and a rectangular slider is fixedly connected to the bottom end of the rectangular rod. The rectangular slider is slidably connected in the sliding groove. The pipe mechanism includes a hydraulic pipe fitted onto the inner tube and an iron piece fixedly installed on the inner wall of the hydraulic pipe and corresponding to the position of the magnet.

[0006] Preferably, an outer tube is fixedly installed at both ends of the connector body around the outer side of the inner tube, and the length of the outer tube is less than the length of the inner tube.

[0007] Preferably, a slot is provided at the position where the magnet is mounted on the rotating ring, the magnet is engaged in the slot, and the magnet and the iron sheet are attracted to each other.

[0008] Preferably, a limit slider is fixedly installed at the protrusion end of the swivel connecting screw.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] In this invention, a rotating ring is fitted onto the inner tube, and a gear that meshes with the toothed ring is connected to the rotating ring. When the rotating ring is rotated, the gear moves along the toothed ring, thereby driving the gear to rotate. This allows the screw meshing with the gear to be conveyed upwards, so that its top plate is held against the inner wall of the hydraulic pipe. The connection can be completed without drilling a threaded hole, which avoids leakage and improves installation efficiency. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a hydraulic pipe fitting sleeve. Example

[0024] Combination Figure 1-5 As shown, this utility model provides a hydraulic pipe fitting sleeve, including a fitting mechanism, a reinforcing mechanism, and a pipe mechanism. The fitting mechanism includes a fitting body 110, inner tubes 120 disposed at both ends of the fitting body 110, a sealing sleeve 130 fixedly fitted onto the end of the inner tube 120, a toothed ring 140 fixedly installed on the inner end of the fitting body 110 and surrounding the outer side of the sealing sleeve 130, and a sliding groove 150 formed in the middle of the outer side of the sealing sleeve 130. Outer tubes 121 are fixedly installed at both ends of the fitting body 110 around the outer side of the inner tube 120, and the length of the outer tube 121 is less than the length of the inner tube 120. The reinforcing mechanism includes a rotating ring 210 slidably fitted onto the middle of the inner tube 120 and located inside the sealing sleeve 130, a magnet 220 snapped onto the surface of the rotating ring 210, and a screw slidably connected to the inner protrusion of the rotating ring 210. The structure includes a rod 230, a gear 240 threadedly connected to the middle of the screw 230, a top plate 250 fixedly connected to the top of the screw 230, a rectangular rod 231 slidably connected to the middle of the screw 230, a rectangular slider 232 fixedly connected to the bottom end of the rectangular rod 231, the rectangular slider 232 slidably connected in the groove 150, a limiting slider 260 fixedly installed on the protrusion end of the rotating ring 210 connected to the screw 230, a limiting groove 241 opened on the gear 240, the limiting groove 241 slidably connected to the bottom end of the limiting slider 260, a sliding block provided on the side of the rotating ring 210 near the sealing sleeve 130, the sliding block slidably connected to the inside of the sealing sleeve 130, and a pipeline mechanism including a hydraulic pipe 310 sleeved on the inner tube 120 and an iron piece 320 fixedly installed on the inner wall of the hydraulic pipe 310 and corresponding to the position of the magnet 220.

[0025] Preferably, a slot 211 is provided at the position where the magnet 220 is installed on the rotating ring 210. The magnet 220 is engaged in the slot 211, and the magnet 220 and the iron plate 320 are attracted to each other. By using the magnet 220 to attract the iron plate 320, the positions of the rotating ring 210 and the hydraulic pipe 310 are fixed together. Thus, when the hydraulic pipe 310 is rotated, the rotating ring 210 is driven to rotate, which ultimately drives the top plate 250 to abut against the inner wall of the hydraulic pipe 310, completing the fixation and ensuring the reliability of the structure.

[0026] Specifically, the rectangular slider 232 is limited by the slide groove 150, so that the rectangular slider 232 has no basis for rotation. Therefore, the rectangular rod 231 connected to it also does not have the function of rotation. Finally, it extends to the screw 230, so that the screw 230 can only move up and down and cannot rotate. At this time, the gear 240 is limited by the limiting slider 260 in conjunction with the limiting groove 241, so that it can only rotate and not move up and down. This maintains the meshing relationship between the gear 240 and the gear ring 140, while driving the screw 230 to move up and down. This ensures that the top plate 250 can be supported against the inner wall of the hydraulic pipe 310, thus improving the practicality of the device.

[0027] The working principle and usage process of this utility model are as follows: First, take out the hydraulic pipe 310 to be connected. Then, according to the indicator lines on the hydraulic pipe 310 and the outer pipe 121, align them and insert the hydraulic pipe 310 into the inner part of the outer pipe 121 until the iron piece 320 inside the hydraulic pipe 310 is attracted to the magnet 220, completing the initial connection. At this time, rotate the hydraulic pipe 310 or the connector body 110 according to the direction indicated by the arrow. As the rotation proceeds, the rotating ring 210 will drive the gear 240 to move along the gear ring 140. Due to the meshing relationship between the gear 240 and the gear ring 140, the gear 240 will start to rotate under the limit of the limiting slider 260, driving the screw 230 with its central thread connection to move upward until the top plate 250 abuts against the inner wall of the hydraulic pipe 310, completing the fixation. Finally, regularly inspect the pipeline to prevent pipeline damage.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
