Description

Technical Field

[0001] The present application relates to the technical field of hose joints, and in particular to an anti-debonding hose joint structure. Background Art

[0002] When two hoses need to be connected, a hose connector is usually used for the connection. Common hose connectors connect two hoses by inserting into the hoses or being inserted by the hoses. They have a simple structure and are easy to use.

[0003] Regarding the above-mentioned related technologies, the hose joint with a simple structure may fall off, that is, the hose joint falls off due to the pressure from the transported object in the hose, causing the hose joint to fail, the transported object to leak and waste, and other consequences, which need to be improved. Utility Model Content

[0004] The purpose of this application is to provide an anti-debonding pipe joint structure to improve the problem of the hose joint falling off due to loose connection.

[0005] The present application provides an anti-debonding pipe joint structure that adopts the following technical solutions:

[0006] A debonding prevention pipe joint structure includes a joint pipe body, one end of the joint pipe body is provided with an insertion port, the other end is provided with an anti-slip pipe, and the side of the anti-slip pipe away from the joint pipe body is provided with a guide fillet; the outer side wall of the anti-slip pipe is circumferentially provided with a plurality of anti-slip protrusions, and the anti-slip protrusions are provided with installation fillets.

[0007] By adopting the above technical solution, different hose connection methods are set at both ends of the joint pipe body, which is convenient for dealing with different connection situations; a guide fillet is set on the side where the anti-slip tube is inserted into the hose, making the insertion of the anti-slip tube easier; the anti-slip protrusion set on the outer wall of the anti-slip tube increases the friction between the anti-slip tube and the hose, so that the joint pipe body will not fall off easily. At the same time, there are installation fillets on the anti-slip protrusions, which reduces the resistance during insertion to a certain extent and facilitates installation.

[0008] Preferably, a fixing ring is provided on a side of the anti-slip tube close to the joint tube body, and a fixing groove is formed between the fixing ring and the joint tube body.

[0009] By adopting the above technical solution, the toughness of the hose is utilized to allow the fixing ring to be inserted into the hose and extend beyond the fixing ring by a certain margin, and then the hose is fixed in the fixing groove using a locking hoop, thereby improving the firmness of the connection between the hose and the joint pipe body.

[0010] Preferably, a soft rubber gasket 1 is provided in the fixing groove.

[0011] By adopting the above technical solution, the friction between the hose and the fixing groove is increased by using the soft rubber gasket, thereby further improving the stability of the connection. The soft rubber gasket can also play a sealing role to reduce the leakage of the transported objects in the hose.

[0012] Preferably, an embedding groove is provided on the inner side wall of the fixing groove, and an embedding protrusion which can be inserted into the embedding groove is provided on the outer side wall of the soft rubber gasket 1.

[0013] By adopting the above technical solution, the embedding protrusion on the soft rubber gasket 1 is inserted into the embedding groove to reinforce the soft rubber gasket 1, thereby improving the stability between the rubber hose and the soft rubber gasket 1.

[0014] Preferably, two positioning protrusions are provided at the bottom of the fixing groove, and the soft rubber gasket is provided with two installation grooves corresponding to the positioning protrusions, and the two positioning protrusions can be inserted into the corresponding two installation grooves; a hollow cavity is provided in the soft rubber gasket between the two installation grooves.

[0015] By adopting the above technical solution, the cooperation between the installation groove and the positioning protrusion is utilized to facilitate the positioning and installation of the soft rubber gasket 1; a hollow cavity is provided in the soft rubber gasket 1, located between the two installation grooves. When the hose is put into the fixing groove and fixed with the locking hoop, the squeezing force of the two positioning protrusions causes the soft rubber gasket 1 to deform, and the hollow cavity gives a certain deformation amplitude. Moreover, due to the setting of the hollow cavity, the entire soft rubber gasket 1 has better elastic recovery ability, which has a pre-tightening effect on the connected hose, making the fixing of the locking hoop more secure.

[0016] Preferably, a mounting chamfer is provided at the connection between the anti-slip tube and the fixing ring.

[0017] By adopting the above technical solution, an installation chamfer is provided at the connection between the anti-slip tube and the fixing ring to facilitate the insertion of the hose, making the installation of the hose joint relatively easy.

[0018] Preferably, a positioning groove is provided on the outer side wall of the anti-slip tube close to the installation chamfer.

[0019] By adopting the above technical solution, a positioning groove is provided to deal with the problem that the hose is not tough enough or has a small diameter and cannot be put through the fixing ring. After the hose is put into the positioning groove, a locking hoop is used to fix the hose, thereby achieving a fixed connection between the hose with insufficient toughness or a small diameter and the hose joint.

[0020] Preferably, a second soft rubber gasket is provided in the positioning groove.

[0021] By adopting the above technical solution, the second soft rubber gasket is used to increase the friction between the hose and the positioning groove, thereby improving the stability of the connection; at the same time, the second soft rubber gasket can also play a sealing role, reducing the possibility of leakage of the transported objects in the hose.

[0022] Preferably, an insertion chamfer is provided on the inner side wall of the insertion port away from the joint pipe body.

[0023] By adopting the above technical solution, an insertion chamfer is provided in the insertion opening, which makes the insertion of the hose relatively easy, thereby facilitating the installation of the hose joint.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A guide radius is provided on one side of the anti-slip tube to reduce resistance to hose insertion and facilitate installation. Anti-slip protrusions are provided on the outer wall of the anti-slip tube to increase friction after insertion and reduce the possibility of falling off. The anti-slip protrusions are also provided with installation radius, making hose installation relatively easy.

[0026] 2. A fixing ring is set between the anti-slip tube and the joint tube body, and a fixing groove is formed between the fixing ring and the joint tube body. A soft rubber washer is installed in the fixing groove. After the hose is inserted into the fixing groove, a locking hoop is used to fix it. The soft rubber washer increases friction and reduces hose leakage. At the same time, in order to meet the fixation of hoses with insufficient toughness or small diameter, a positioning groove is set near the fixing ring on the anti-slip tube to fix the hose. A soft rubber washer is installed in the positioning groove, which also increases friction and reduces hose leakage.

[0027] 3. The inner wall of the insertion port is provided with an insertion chamfer, which makes it relatively easy to insert the hose into the insertion port and facilitates the installation of the hose joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0034] An anti-debonding pipe joint structure, referring to Figure 1 and Figure 3 , including a joint tube body 1, one end of the joint tube body 1 is an insertion port 2, and the other end is an anti-slip tube 3; the anti-slip tube 3 has a guide fillet 31 at the end away from the joint tube body 1, which reduces the resistance when inserting the hose (not shown in the figure), thereby facilitating the installation of the hose; the outer wall of the anti-slip tube 3 is circumferentially provided with anti-slip protrusions 32, the main function of the anti-slip protrusions 32 is to increase the friction between the anti-slip tube 3 and the hose and reduce the possibility of the hose falling off; at the same time, the anti-slip protrusion 32 is provided with an installation fillet 321, which facilitates the insertion of the anti-slip tube 3 into the hose; the inner wall of the insertion port 2 at the end away from the joint tube body 1 is provided with an insertion chamfer 21, which can make the insertion of the hose more labor-saving and facilitate the installation of the hose.

[0035] Reference Figure 2 A fixing ring 4 is provided at one end of the protective tube 3 close to the joint tube body 1, and a fixing groove 41 is provided between the fixing ring 4 and the joint tube body 1. When inserting the hose, the hose is put through the fixing ring 4 and covers the fixing groove 41 and then fixed, which can further stabilize the hose so that the joint tube body 1 will not easily slip out of the hose, and an installation chamfer 43 is provided at the connection between the anti-slip tube 3 and the fixing ring 4, which can make the hose relatively labor-saving when passing through the fixing ring 4 and facilitate installation; at the same time, a soft rubber pad 42 is installed on the bottom surface of the fixing groove 4, and the material of the soft rubber gasket 42 is rubber. The soft rubber pad 42 enhances the friction between the hose and the fixing groove 4, making the connection more stable, and the soft rubber pad 42 can also play a certain sealing role to reduce hose leakage.

[0036] Reference Figure 4, the soft rubber pad 1 42 is provided with an embedded protrusion 421, and the inner wall of the fixing groove 41 is correspondingly provided with an embedded groove 411. The embedded protrusion 421 is inserted into the embedded groove 411 to further stabilize the soft rubber gasket 1 42, thereby ensuring the stability of the hose connection; a positioning protrusion 412 is provided at the bottom of the fixing groove 41, and the soft rubber gasket 1 42 is provided with an installation groove 422 corresponding to the positioning protrusion 412. The soft rubber gasket 1 42 is positioned and fixed by inserting the positioning protrusion 412 into the installation groove 422; the soft rubber gasket 1 42 2, a hollow cavity 423 is provided between the two mounting grooves 422. When the rubber hose covers the fixing groove 41, the hollow cavity 423 is compressed when the locking hoop is used to fix it. Combined with the supporting and squeezing force of the two positioning protrusions 412, the soft rubber gasket 1 42 is deformed, and the hollow cavity 423 is given a certain deformation amplitude. In addition, due to the setting of the hollow cavity 423, the entire soft rubber gasket 1 42 has a good elastic recovery ability, which has a pre-tightening effect on the connected rubber hose and further stabilizes the installation of the rubber hose.

[0037] Reference Figure 3 In order to ensure the stability of the connection of the hose that is not tough enough or has a small diameter and cannot be fixed through the fixing ring 4, a positioning groove 33 is provided on the side of the anti-slip tube 3 near the installation chamfer 43, which plays a similar role to the fixing groove 41, and a soft rubber gasket 331 is installed in the positioning groove 33. The material of the soft rubber gasket 331 is rubber, which can increase the friction between the hose and the positioning groove 33, thereby making the connection more secure. At the same time, the soft rubber gasket 33 can also play a certain sealing role to reduce hose leakage.

[0038] The implementation principle of the embodiment of this application is:

[0039] To connect the rubber hose to the insertion port 2, you only need to insert the rubber hose along the insertion chamfer 21 and then fix it with a locking hoop (not shown in the figure); when connecting the rubber hose to the anti-slip tube 3, first align the rubber hose with the guide fillet 31 of the anti-slip tube 3 and insert it, and then put it over the anti-slip protrusion 32. Due to the setting of the installation fillet 321, it can be inserted more easily; when it is put in front of the fixing ring 4, the fixing ring 4 is also put into the rubber hose along the installation chamfer 43, and then the rubber hose is moved forward to cover the fixing groove 41; a soft rubber gasket 42 is installed in the fixing groove 41. When installing the soft rubber gasket 42, first align the soft rubber gasket 42 with the guide fillet 31 of the anti-slip tube 3. The embedding protrusion 421 is inserted into the embedding protrusion 411 on the side wall of the fixing groove 41, and at the same time, the positioning protrusion 412 at the bottom of the fixing groove 41 is inserted into the installation groove 422 of the soft rubber gasket 42 to complete the fixation of the soft rubber gasket 42; at this time, the locking hoop is used to circle the hose covering the part of the fixing groove 41 and tighten it to make the hose fit tightly with the soft rubber gasket 42 at the bottom of the fixing groove 41, and a hollow cavity 423 is provided inside the soft rubber gasket 42. When the locking hoop is tightened, a depression will be generated between the two positioning protrusions 412, so that the locking hoop is fixed more firmly.

[0040] When the rubber tube is not flexible enough or its diameter is too small to be sleeved on the fixing ring 4, the rubber tube is stopped before being sleeved on the fixing ring 4, and is fixed by the positioning groove 33 arranged on the side close to the installation chamfer 43 of the anti-skid tube 3. The soft rubber gasket two 331 is installed in the positioning groove 33. The rubber tube covering the part of the positioning groove 33 is clamped by the locking hoop, and is pulled and fixed so that the rubber tube is tightly attached to the soft rubber gasket two 331 in the positioning groove 33, and the rubber tube is fixed and installed without being separated.
