[0008] As described above, a screw-in hose sealing joint, the hose connection position includes a screw-on cap thread structure, an anti-dislocation installation, and a screw-in connection hole. The screw-on cap thread structure is connected in cooperation with a mining hose, and the screw-on cap is inserted into the hose connection body through the screw-in connection hole and abuts against the hose connection body through the anti-dislocation installation to limit the position.

[0009] In the screw-in hose sealing joint as described above, the cap screw thread structure is provided with a hose connection thread and a thread connection groove.

[0010] As described above, a screw-in hose sealing joint has an anti-slipping abutment plane, a reserved connecting cavity and a snap-in hole at the anti-slipping installation position. The screw cap is snapped into the hose connecting body through the snap-in hole and abuts against the hose connecting body through the anti-slipping abutment plane to limit the position. The reserved connecting cavity is used to store excess mining hose.

[0011] As described above, a screw-in hose sealing joint, the mining hose is provided with a hose body, a hose support structure, and a hose outer layer. The hose body is provided with a hose cavity for conveying materials. The hose support structure is equidistantly connected to the hose body to support the hose body. The hose outer layer is connected to the hose support structure and the hose support structure is limited by the hose outer layer. The hardness of the hose support structure material is greater than that of the hose outer layer to ensure that the mining hose is not easy to collapse when used as a whole.

[0012] In the above-mentioned screw-in hose sealing joint, the hose supporting structure is spirally wound around the hose body at equal intervals to form a thread for connecting the hose connecting thread.

[0013] As described above, a screw-in hose sealing joint, the hose connecting body is also provided with a cover anti-detachment block and a main body conveying cavity, the hose mounting position is also provided with a sealing groove, the sealing groove can be used for a sealing ring to be inserted for sealing, the cover anti-detachment block is arranged between the hose mounting position and the cover mounting position, and the main body conveying cavity is connected to the hose cavity to convey materials.

[0014] As described above, in a screw-in hose sealing joint, the cross-section of the anti-slip block of the screw cap is of trapezoidal design and the screw cap contact end of the anti-slip block is a trapezoidal right-angled side, and the screw cap contact end abuts against the anti-slip abutment plane to limit the screw cap.

[0015] In the screw-in hose sealing joint as described above, the maximum width of both sides of the cover anti-dropping block is smaller than the minimum width of the threads on both sides of the hose connection thread.

[0016] In the screw-in hose sealing joint as described above, the hose connection body and the screw-on cover are made of hard polyvinyl chloride.

[0017] Implementing the embodiments of the present invention has the following beneficial effects:

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, an embodiment of the present invention provides a screw-in hose sealing joint, comprising:

[0028] A hose connection body 1, wherein the hose connection body 1 is provided with a hose installation position 11 and a cap screwing installation position 12, wherein the hose installation position 11 is used to connect a mining hose 3;

[0029] A screw cap 2, the screw cap 2 is connected to the screw cap installation position 12, the screw cap 2 is provided with a hose connection position 21, and the hose connection position 21 is used to connect the mining hose 3;

[0030] The mining hose 3 is connected to the hose installation position 11 through the inner side and connected to the hose connection position 21 through the outer side to complete the sealing connection.

[0031] Specifically, the hose connection position 21 includes a screw-on cap thread structure 211, an anti-disengagement position 212, and a screw-in connection hole 213. The screw-on cap thread structure 211 cooperates with the mining hose 3 to lock the mining hose 3; the screw-in connection hole 213 is flush with the lowest end of the inner side of the screw-on cap 2, so that the screw-on cap 2 can be quickly inserted into the hose connection body 1 through the screw-in connection hole 213 and abut against the hose connection body 1 through the anti-disengagement position 212 to limit the position, thereby preventing the screw-in hose sealing joint from loosening after being connected to the mining hose 3, resulting in the risk of leakage.

[0032] Furthermore, the screw cap thread structure 211 is provided with a hose connection thread 2111 and a thread connection groove 2112. The hose connection thread 2111 is designed not to contact the hose connection body 1, so that the screw cap 2 can be quickly inserted into the hose connection body 1 to save installation time; the thread connection groove 2112 is a flat design, which on the one hand allows the thread to be easier to insert and rotate, thereby making the installation process simpler; on the other hand, the flat groove reduces the contact area of ​​the thread, so that the wear between the threads can be reduced, thereby extending the service life of the thread of the mating connector; such a design can ensure that the mining hose 3 can be quickly connected to the screw-in hose sealing joint.

[0033] Furthermore, the installation anti-slip position 212 is provided with an anti-slip abutment plane 2121, a reserved connection cavity 2122, and a snap-in hole 2123. The screw cap 2 is inserted into the hose connection body 1 through the snap-in hole 2123 and abuts against the hose connection body 1 through the anti-slip abutment plane 2121 for limiting the position. The reserved connection cavity 2122 is used to store the excess mining hose 3. The design of the anti-slip abutment plane 2121 enables the screw cap 2 to abut against the hose connection body 1 to prevent the screw cap 2 from moving and causing leakage during material transportation. The reserved connection cavity 2122 can ensure that the non-threaded portion of the mining hose 3 connected to the screw cap 2 will not directly abut against the screw cap 2 to cause an unstable connection, thereby ensuring the stability of the overall structure after connection. The screw cap 2 can be quickly inserted into the screw cap installation position (12) through the snap-in hole 2123 to achieve quick installation and save installation time.

[0034] Furthermore, the mining hose 3 is provided with a hose body 31, a hose support structure 32, and a hose outer layer 33. The hose body 31 is provided with a hose cavity 311 for conveying materials. The hose support structure 32 is equidistantly connected to the hose body 31 to support the hose body 31. The hose outer layer 33 is connected to the hose support structure 32 and the hose support structure 32 is limited by the hose outer layer 33. The hardness of the hose support structure 32 is greater than that of the hose outer layer 33. The hose support structure 32 is equidistantly connected to the hose body 31 and the hose support structure 32 is made of hard material. The hose outer layer 33 is made of soft material and is wrapped and connected to the hose support structure 32 to fix the position of the hose support structure 32. The combination of soft and hard materials makes the structure of the mining hose 3 more stable, so that the mining hose 3 is not easy to collapse when connected to the screw-in hose sealing joint, and the maximum conveying capacity is always maintained.

[0035] Furthermore, the hose support structure 32 is equidistantly spirally wound around the hose body 1 to form a thread for connecting the hose connection thread 2111. The equidistant spiral design is sturdy and durable. On the one hand, the connection of the mining hose 3 can provide good sealing performance and withstand a certain pressure to ensure that the connection will not break or leak, avoid liquid or gas leakage, and ensure the normal operation of the equipment; on the other hand, the mining hose 3 can be installed and disassembled by a simple rotation action, which is relatively simple to operate and does not require complicated tools, thereby reducing the technical difficulty of installing the mining hose 3 and the product has strong applicability;

[0036] The spiral inclination angle of the hose support structure 32 ranges from 84° to 88°, preferably 86°. A larger spiral inclination angle can increase the stability and load-bearing capacity of the hose support structure 32, making it more suitable for bearing larger forces and torques. The 86° spiral inclination design can provide a better self-locking effect, avoid the torque force generated in a complex operation environment causing the hose connection to loosen automatically, and improve the reliability of the hose connection;

[0037] The hose support structure 32 is made of hard polyvinyl chloride, which has good corrosion resistance and can resist corrosion from various chemical substances, and is suitable for use in mining hoses in harsh environments. In addition, hard polyvinyl chloride has good wear resistance, which makes the hose support structure 32 less susceptible to wear when conveying materials, and can extend the service life of the hose support structure 32, so as to ensure that the hose support structure 32 is not easily worn during use and affects the support of the hose body 1, causing the hose to be deflated, thereby affecting the conveying of materials;

[0038] The hose support structure 32 is designed with a circular cross section. The circular cross section design makes the hose support structure 32 more evenly stressed, reduces the possibility of stress concentration, and improves the stability and load-bearing capacity of the hose support structure 32 to ensure that the hose body 1 is always in the maximum conveying capacity state when conveying materials;

[0039] The outer layer 33 of the hose is provided with a connecting flat groove 331 to enable the hose to be better connected to the screw-in sealing joint. The flat design of the connecting flat groove 331, on the one hand, allows the thread to be inserted and rotated more easily, thereby making the installation process simpler; on the other hand, the flat groove reduces the contact area of ​​the thread, so that the wear between the threads can be reduced, thereby extending the service life of the thread of the matching connector;

[0040] The hose support structure 32 and the screw cap thread structure 211 are used to realize the detachable connection between the screw-in sealing joint and the mining hose 3. Such a design enables the hose support structure 32 to be locked and sealed after being threadedly connected with the screw-in sealing joint to ensure the reliability and sealing of the connection and facilitate disassembly;

[0041] The outer layer 33 of the hose is made of soft polyvinyl chloride and is wrapped and connected to the hose support structure 32. The outer layer 33 of the hose is made of soft polyvinyl chloride. On the one hand, soft polyvinyl chloride has good corrosion resistance, which can effectively resist the erosion of the atmosphere, water and chemicals on the outer layer 33 of the hose, and adapt to a variety of working environments, thereby extending the service life of the hose; on the other hand, soft polyvinyl chloride has a certain flexibility, which can reduce the damage caused by external impact, increase the durability of the structure and the softness of the mining hose; at the same time, the soft polyvinyl chloride used in the present invention has anti-static properties with the addition of conductive fillers or static dissipators, which can eliminate static charges accumulated during contact or friction, and reduce the risks in the process of conveying materials. Such a design can achieve that after the outer layer 33 of the hose is wrapped and connected to the hose support structure 32, the mining hose as a whole can be easily bent, adjusted and installed, thereby reducing the difficulty of installing the hose for outdoor operations and making the angle easy to adjust and install;

[0042] The hose body 31, hose support structure 32 and hose outer layer 33 are of one-piece molding design. The one-piece molding design, on the one hand, can provide a more secure connection, so that the mining hose can withstand higher pressures, avoiding the loosening or leakage problems that are prone to occur at the connection of ordinary hoses, thereby improving the safety of conveying materials; on the other hand, through the one-piece molding design, the connection between the mining hose and the screw-in sealing joint can be achieved through the threaded connection of the hose support structure 32, and there is no need to use bolts and nuts for connection reinforcement, which simplifies the connection and installation of the mining hose, thereby reducing the process and time during the installation process and improving work efficiency.

[0043] Furthermore, the hose connection body 1 is also provided with a cover anti-detachment block 14, a connection body tail end 16, a hose inclined installation end 17, and a body conveying cavity 18. The hose installation position 11 is also provided with a sealing groove 13, and the sealing groove 13 can be used for a sealing ring 15 to be inserted to seal the mining hose 3 to ensure that there is no risk of leakage after connection; the cover anti-detachment block 14 is arranged between the hose installation position 11 and the cover installation position 12 to abut the screw cover 2 to ensure the structural stability of the mining hose 3 and the screw-in hose sealing joint after the overall connection; the inclined design of the hose inclined installation end 17 facilitates the quick connection of the body conveying cavity 18 to the hose cavity 311 to ensure the stable transportation of materials in the two cavities; the connection body tail end 16 facilitates the screw-in hose sealing joint to be connected to equipment connectors such as two-way elbows, three-way elbows and ball valves.

[0044] Furthermore, the cross-section of the cap-tightening anti-detachment block 14 is of trapezoidal design and the cap-tightening anti-detachment block 14 is provided with a cap-tightening contact end 141 as a trapezoidal right-angled side. The trapezoidal design of the cap-tightening anti-detachment block 14 has a larger contact area, which can improve the stability and bearing capacity of the anti-detachment abutment plane 2121 after abutment with the cap-tightening contact end 141, and facilitate the installation and disassembly of the screw cap 2. At the same time, it can effectively reduce the risk of loosening and falling off after the overall structure is connected, and better limit the screw cap 2.

[0045] Furthermore, the maximum width on both sides of the screw cap anti-dropping block 14 is smaller than the minimum width of the threads on both sides of the hose connection thread 2111. Such a design facilitates the screw cap 2 to be quickly inserted into the screw-in connection hole 213 and abut against the screw cap anti-dropping block 14 to complete the stable connection of the mining hose 3.

[0046] Furthermore, the hose connection body 1 and the screw cover 2 are made of rigid polyvinyl chloride. Rigid polyvinyl chloride has good corrosion resistance and can resist corrosion from various chemical substances. It is suitable for the use of screw-in hose sealing joints in harsh environments. Rigid polyvinyl chloride has good wear resistance, which makes the screw-in hose sealing joint less susceptible to wear when conveying materials, thereby ensuring the connection reliability between the mining hose and the screw-in hose sealing joint and reducing maintenance work.
