[0018] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: a single-layer fabric reinforced rubber tube for sandblasting, comprising: an inner tube 1; a connecting sleeve 2, the outer wall of the connecting sleeve 2 is fixedly connected to the outer wall of the inner tube 1; an outer tube 3, the outer wall of the outer tube 3 is fixedly connected to the outer wall of the connecting sleeve 2; the connecting sleeve 2 includes a fixing sleeve 21, the side wall inside the fixing sleeve 21 is provided with a connecting groove 22, the side wall outside the fixing sleeve 21 is fixedly connected with a fixing flange 23, a connecting hole 24 is provided in the wall of the fixing flange 23, and an insertion hole 25 is provided on the outer wall of the fixing flange 23 away from the connecting hole 24. The fixing sleeve 21 is tightly connected to the outer tube 3 through the connecting groove 22 and is fixed to the inner tube 1 to ensure the integrity of the rubber tube. The connecting hole 24 on the fixing flange 23 is used to connect to external equipment, wherein the insertion hole 25 is connected to the connecting hole 24. The larger insertion hole 25 facilitates the insertion of fixing parts such as bolts, making installation and fixation convenient.

[0019] The inner side wall of the fixing sleeve 21 is fixedly connected to the outer wall of the outer hose 3 through the connecting groove 22 , the insertion hole 25 is connected to the connecting hole 24 , and the inner side wall of the fixing sleeve 21 is fixedly connected to the outer wall of the inner hose 1 .

[0020] The side of the fixing sleeve 21 away from the connecting flange is fixedly connected with a bonding piece 4, and the side of the bonding piece 4 away from the fixing sleeve 21 is fixedly connected to the outer wall of the inner rubber tube 1. The side wall outside the inner rubber tube 1 is sleeved with a buffer layer 5, and the side wall outside the buffer layer 5 is fixedly connected with an adhesive layer 6. The side of the adhesive layer 6 away from the buffer layer 5 is fixedly connected with a fabric layer 7. The bonding piece 4 is located on one side of the fixing sleeve 21 and is fixedly connected to the outer wall of the inner rubber tube 1. It plays a role in strengthening the connection between the connecting sleeve 2 and the inner rubber tube 1, preventing separation during use, enhancing the tightness of the connection, and improving the reliability of the rubber tube.

[0021] The fabric layer 7 includes a fabric sleeve 71, a spiral fabric mesh 72 is provided on the fixed path of the side wall inside the fabric sleeve 71, and a reverse fabric mesh 73 is fixedly connected to the outer wall of the spiral fabric mesh 72.

The spiral fabric mesh 72 and the reverse fabric mesh 73 are intertwined with each other, which increases the contact area between the fabric sleeve 71 and the adhesive layer 6, thereby improving the overall stability of the fabric layer 7. The mesh structure composed of the spiral fabric mesh 72 and the reverse fabric mesh 73 intertwined with each other has good tensile strength, so the rubber tube will effectively absorb vibration during bending and use, thereby improving the strength and pressure resistance of the rubber tube. The fabric layer 7 protects the internal fabric mesh through the fabric sleeve 71 and is connected to the surrounding components at the same time, which enables the buffer layer 5 to effectively protect the rubber tube from the impact force.

[0022] Working principle:

[0023] When in use, the inner rubber tube 1 serves as the inner layer of the reinforced rubber tube and is in direct contact with the transported sandblasting medium. Since the rubber constituting the inner rubber tube 1 has good wear resistance and corrosion resistance, it can withstand the impact and friction of the medium during the sandblasting process, while preventing leakage of the medium, thereby ensuring good adaptability to the sandblasting medium and extending the service life of the rubber tube. Based on this, structures are added to the rubber tube to achieve other effects, such as adding a connecting sleeve 2 to increase the connection convenience of the reinforced rubber tube, and designing a fabric reinforcement layer to give the rubber tube more stable performance.

[0024] The connecting sleeve 2 is mainly composed of a fixing sleeve 21, a connecting groove 22, a fixing flange 23, a connecting hole 24 and an insertion hole 25. The fixing sleeve 21 is tightly connected to the outer rubber tube 3 through the connecting groove 22 and is fixed to the inner rubber tube 1 to ensure the integrity of the rubber tube. The connecting hole 24 on the fixing flange 23 is used to connect with external equipment, wherein the insertion hole 25 is connected to the connecting hole 24. The larger insertion hole 25 facilitates the insertion of fixing parts such as bolts, and is convenient for installation and fixation. The connecting sleeve 2 plays the role of connecting the inner rubber tube 1 and the outer rubber tube 3 through the fixing sleeve 21, thereby ensuring the structural stability of the rubber tube. At the same time, the design of the fixing flange 23 and the connecting hole 24 enables the rubber tube to be conveniently connected to external equipment, thereby improving the convenience of use.

[0025] The bonding piece 4 is located on one side of the fixing sleeve 21 and is fixedly connected to the outer wall of the inner rubber tube 1. It plays a role in strengthening the connection between the connecting sleeve 2 and the inner rubber tube 1, preventing separation during use, enhancing the tightness of the connection, and improving the reliability of the rubber tube;

[0026] The outer side wall of the middle area of the inner rubber hose 1 is sleeved with a buffer layer 5, wherein the buffer layer 5 is polyester fiber. The buffer layer 5 can absorb and weaken the impact force generated during the sandblasting process, reducing damage to the rubber hose as a whole. The side wall outside the buffer layer 5 is connected to the fabric layer 7 through an adhesive layer 6, and the fabric layer 7 is composed of a fabric sleeve 71, a spiral fabric mesh 72 and a reverse fabric mesh 73. The spiral fabric mesh 72 and the reverse fabric mesh 73 are interwoven with each other, which increases the contact area between the fabric sleeve 71 and the adhesive layer 6, thereby improving the overall stability of the fabric layer 7. The spiral fabric mesh 72 and the reverse fabric mesh 73 are interwoven with each other, thereby increasing the contact area between the fabric sleeve 71 and the adhesive layer 6, thereby improving the overall stability of the fabric layer 7. The mesh structure composed of the interwoven fabric meshes 73 has good tensile strength, so the rubber tube will effectively absorb vibrations during bending and use, thereby improving the strength and pressure resistance of the rubber tube. The fabric layer 7 protects the internal fabric mesh through the fabric sleeve 71 and is connected to the surrounding components. This allows the buffer layer 5 to effectively protect the rubber tube from impact force, and at the same time allows the adhesive layer 6 to ensure a firm bond between the fabric layer 7 and the buffer layer 5. The fabric layer 7 improves the strength and pressure resistance of the rubber tube through its own structure, so that it can adapt to the requirements of sandblasting work.
