Description

Technical Field

[0001] This utility model relates to the field of threaded connector technology, specifically to a hydraulic hose threaded connector that is easy to assemble. Background Technology

[0002] A hydraulic hose threaded fitting is a threaded pipe connector primarily used in industrial and domestic applications. It simplifies pipe connections, makes disassembly and replacement easier, and significantly reduces pipe connection costs. This type of fitting is commonly used to connect hydraulic hoses to other hydraulic components, ensuring a secure and leak-proof connection to meet the requirements of hydraulic systems.

[0003] Currently, threaded connectors are typically assembled onto hydraulic hoses using a crimping method. This involves inserting the end of the hydraulic hose between the core and sleeve of the threaded connector, and then applying pressure to the sleeve to fix the threaded connector onto the hydraulic hose. However, this assembly method requires specialized crimping equipment, and the threaded connector is not easy to disassemble later; the hydraulic hose and threaded connector can only be replaced as a whole. Therefore, we propose a hydraulic hose threaded connector that is easy to assemble. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic hose threaded connector that is easy to assemble. It has the advantages of being easy to assemble the threaded connector onto the hydraulic hose and also easy to disassemble the threaded connector, so as to facilitate the replacement of the hydraulic hose or the threaded connector. It solves the problem that the current threaded connector is usually assembled onto the hydraulic hose by crimping, but this assembly method requires professional crimping equipment and the threaded connector is not easy to disassemble later, so only the hydraulic hose and the threaded connector can be replaced as a whole.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic hose threaded connector that is easy to assemble, comprising a semi-circular tube A, a core rod, a screw rod, and a semi-circular tube B. A connecting nut is fixedly connected to one end of the core rod. Threaded holes are provided at the four corner positions of the outer surface of the semi-circular tube A. Insertion holes are provided at the four corner positions of the outer surface of the semi-circular tube B. The screw rod passes through the threaded holes and the insertion holes. A fixing nut is movably sleeved on the outer surface of the screw rod. A fixing plate is fixedly installed on the outer surface of the core rod near the connecting nut. Dovetail grooves are provided on the inner side of the fixing plate near the upper and lower surfaces. Dovetail blocks are provided on one side of the outer surfaces of the semi-circular tube A and the semi-circular tube B, and the dovetail blocks are located inside the dovetail grooves.

[0006] Preferably, the outer surface of the core rod is provided with a plurality of annular grooves at equal intervals, and the inner walls of the semicircular tube A and the semicircular tube B are provided with a plurality of raised pressure strips at equal intervals.

[0007] Preferably, the raised pressure strips on the inner walls of the semicircular tubes A and B correspond one-to-one with the annular grooves on the outer surface of the core rod.

[0008] Preferably, a pin hole is provided on the outer surface of the screw near the end position, and a pin is provided inside the pin hole.

[0009] Preferably, slots are symmetrically distributed on the upper surface of the semicircular tube A near the front and rear surfaces, and protruding inserts are symmetrically distributed on the lower surface of the semicircular tube B near the front and rear surfaces.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention, by incorporating a core rod, connecting nut, semicircular tube A, semicircular tube B, dovetail groove, dovetail block, fixing plate, screw, and nut, achieves the effect of facilitating the assembly and disassembly of threaded connectors onto hydraulic hoses, thus enabling easy replacement of either the hydraulic hose or the threaded connector. The end of the hydraulic hose is fitted onto the core rod. Rotating the screw causes the dovetail block to slide within the dovetail groove. Simultaneously, semicircular tubes A and B align to form a sleeve with open ends, fixing the end of the hydraulic hose between the sleeve and the core rod, allowing the threaded connector to be assembled onto the hydraulic hose. This assembly process requires only a wrench, eliminating the need for specialized crimping equipment. Furthermore, during subsequent disassembly of the threaded connector and hydraulic hose, turning the screw separates the joined semicircular tubes A and B, completing the disassembly of the hydraulic hose and threaded connector.

[0012] This invention achieves the effect of preventing the hydraulic hose from slipping off the threaded joint by setting a raised pressure strip and an annular groove. After the semicircular tube A and semicircular tube B are connected, the raised pressure strip on the inner wall of the tube applies pressure to the hydraulic hose, causing the deformed part of the hydraulic hose to enter the annular groove, thereby preventing the hydraulic hose from slipping off the core rod.

[0013] This invention achieves a precise docking effect between semi-circular tube A and semi-circular tube B through the use of slots and protruding inserts. When semi-circular tube A and semi-circular tube B are docked to form a sleeve with open ends, the protruding inserts are inserted into the slots to position the docking of semi-circular tube A and semi-circular tube B, and also make the sleeve structure formed after docking more stable.

[0014] By setting a pin and a pin hole, this utility model can use the pin inside the pin hole to limit the fixing nut on the screw, so as to prevent the fixing nut from loosening and falling off, and ensure that the end of the hydraulic hose is fixed on the core rod, so as to prevent the hydraulic hose from slipping off the core rod.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figures 1-6 As shown, the present invention proposes a hydraulic hose threaded connector that is easy to assemble, comprising a semi-circular tube A1, a core rod 2, a screw rod 3, and a semi-circular tube B4. One end of the core rod 2 is fixedly connected to a connecting nut 5. The core rod 2 is hollow inside and communicates with the connecting nut 5. The connecting nut 5 and the hydraulic equipment are fixed by threads. Threaded holes 10 are provided at the four corner positions on the outer surface of the semi-circular tube A1, and insertion holes 8 are provided at the four corner positions on the outer surface of the semi-circular tube B4. The screw rod 3 passes through the threaded holes 10 and the insertion holes 8. After the semi-circular tubes A1 and B4 are joined together, a sleeve with open ends is formed, and the core rod 2 passes through the sleeve. The end of the hydraulic hose is fixed between the core rod 2 and the sleeve.

[0024] A fixing nut 14 is movably fitted onto the outer surface of the screw 3. A pin hole 13 is provided near the end of the outer surface of the screw 3, and a pin 12 is provided inside the pin hole 13. The pin 12 inside the pin hole 13 can limit the fixing nut 14 on the screw 3 to prevent the fixing nut 14 from loosening and falling off, ensuring that the end of the hydraulic hose is fixed on the core rod 2, and preventing the hydraulic hose from slipping off the core rod 2. A fixing plate 16 is fixedly installed on the outer surface of the core rod 2 near the connecting nut 5. Dovetail grooves 17 are provided on the inner side of the fixing plate 16 near the upper and lower surfaces. Dovetail blocks 9 are provided on one side of the outer surface of the semicircular tubes A1 and B4, and the dovetail blocks 9 are located inside the dovetail grooves 17. The dovetail blocks 9 and the dovetail grooves 17 limit the semicircular tubes A1 and B4 to prevent the semicircular tubes A1 and B4 and the hydraulic hose from slipping off the core rod 2 together.

[0025] In use, the end of the hydraulic hose is fitted onto the core rod 2. By rotating the screw 3, the dovetail block 9 slides inside the dovetail groove 17. Simultaneously, the semicircular tubes A1 and B4 are joined to form a sleeve with open ends. The end of the hydraulic hose is then fixed between the sleeve and the core rod 2, allowing the threaded connector to be assembled onto the hydraulic hose. This assembly process only requires a wrench and does not require specialized crimping equipment. Furthermore, when disassembling the threaded connector and hydraulic hose, the screw 3 is turned to separate the joined semicircular tubes A1 and B4, thus completing the disassembly of the hydraulic hose and threaded connector, facilitating their replacement. Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the present invention proposes a hydraulic hose threaded connector that is easy to assemble. Compared with Embodiment 1, this embodiment also includes a plurality of annular grooves 15 evenly distributed on the outer surface of the core rod 2, and a plurality of raised pressure strips 7 evenly distributed on the inner walls of the semicircular tube A1 and the semicircular tube B4. The raised pressure strips 7 on the inner walls of the semicircular tube A1 and the semicircular tube B4 correspond one-to-one with the annular grooves 15 on the outer surface of the core rod 2.

[0027] In this embodiment, after the semicircular tube A1 and the semicircular tube B4 are connected, the protruding pressure strip 7 on the inner wall of the tube applies pressure to the hydraulic hose, and causes the deformed part of the hydraulic hose to enter the annular groove 15 to prevent the hydraulic hose from slipping off the core rod 2. Example

[0028] like Figures 1-3As shown, the present invention proposes a hydraulic hose threaded connector that is easy to assemble. Compared with the first embodiment, this embodiment also includes slots 11 symmetrically distributed on the upper surface of the semi-circular tube A1 near the front and rear surfaces, and protruding inserts 6 symmetrically distributed on the lower surface of the semi-circular tube B4 near the front and rear surfaces.

[0029] In this embodiment, when the semicircular tube A1 and the semicircular tube B4 are joined together to form a sleeve with open ends, the protruding insert 6 is inserted into the slot 11 to position the connection between the semicircular tube A1 and the semicircular tube B4, and also to make the sleeve structure after the connection is formed more stable.
