Description

Technical Field

[0001] The utility model belongs to the technical field of a hydraulic pipe joint, and more specifically, particularly relates to a double-reinforced leak-proof positioning hydraulic pipe fitting joint. Background Art

[0002] With the progress of society and the increase of enterprise productivity, mechanical production in people's production activities, from large machinery to small parts, greatly promotes the productivity of enterprises. Especially in the field of hydraulic technology, social development is extremely rapid, and various hydraulic parts are constantly improved and updated to replace the original hydraulic parts. Among them, the hydraulic pipe joint has a relatively large market demand. However, various hydraulic pipe joints with different shapes and functions appear in the market.

[0003] Based on the above, the inventor found the following problems: The current hydraulic pipe joint has a poor sealing effect. During the installation process of the pipe fitting joint, the sealing ring is overly deformed, and in the case of frequent disassembly and assembly, the sealing ring is extremely easy to be damaged, resulting in a deteriorated sealing effect. Secondly, the existing hydraulic pipe joint lacks reinforcement, and the joint connection is prone to falling off. The above two problems are both likely to cause liquid leakage.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a double-reinforced leak-proof positioning hydraulic pipe fitting joint, in order to achieve the purpose of having more practical value. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a double-reinforced leak-proof positioning hydraulic pipe fitting joint to solve the problem of liquid leakage of the current hydraulic pipe fitting joint.

[0006] The purpose and effect of the double-reinforced leak-proof positioning hydraulic pipe fitting joint of the utility model are achieved by the following specific technical means:

[0007] The double-reinforced leak-proof positioning hydraulic pipe fitting joint includes a main joint and a sub-joint. A limiting ring is provided on the side wall of the main joint, and a groove is provided on the side wall of the sub-joint. The groove matches the limiting ring. The inner wall and outer wall of the limiting ring are provided with inclined surfaces, and the two sides of the groove are provided with inclined cutting surfaces that match the inclined surfaces. A sealing gasket is installed on the surface of the inclined surface. A threaded collar is sleeved on the periphery of the main joint, and the threaded collar is threadedly connected to the outer wall of the main joint. A fixing ring is sleeved on the periphery of the sub-joint, and a pair of bolts are symmetrically inserted into the side wall of the fixing ring. One end of the bolt is threadedly connected to the surface of the threaded collar.

[0008] Further, anti-slip rings are provided on the outer walls of the main joint and the sub-joint.

[0009] Further, threads are provided on the outer walls of the main joint and the sub-joint, and the two sections of threads are continuous.

[0010] Further, a limiting block is provided on the outer wall of the limiting ring, and a sliding groove is formed on the inner wall of the groove.

[0011] Further, a pair of threaded holes are provided on the side wall of the threaded sleeve ring, and a pair of binding holes are formed on the side wall of the fixing ring.

[0012] Further, a rubber gasket is provided on the inner wall of the fixing ring.

[0013] Further, a stop block is provided on the outer wall of a pair of the bolts.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the cooperation of the limiting ring and the groove, when the limiting ring is inserted into the groove, the sealing gasket on the inclined surface of the main joint is closely attached to the inclined cutting surface of the sub-joint. Since the front end of the limiting ring abuts against the bottom of the groove, the sealing gasket will not be excessively deformed, so that the sealing gasket reaches the best sealing effect, and at the same time, the durability of the sealing gasket is improved. Through the cooperation of the threaded sleeve ring and the surface threads of the main joint and the sub-joint, the main joint and the sub-joint are fixed. By using bolts to fix the fixing ring and the threaded sleeve ring, the loosening and falling off of the threaded sleeve ring caused by the pipeline shaking are prevented, which affects the sealing effect, and further the occurrence of liquid leakage is avoided.

[0026] Embodiment:

[0027] As shown in Figure 1 to Figure 5 shown:

[0028] The utility model provides a double-reinforced leak-proof positioning hydraulic pipe fitting joint, which includes a main joint 1 and a sub-joint 2. A limit ring 3 is provided on the side wall of the main joint 1, and a groove 4 is provided on the side wall of the sub-joint 2. The groove 4 matches the limit ring 3. Bevels 5 are provided on the inner wall and outer wall of the limit ring 3, and beveled surfaces 6 matching the bevels 5 are provided on both sides of the groove 4. A sealing gasket 7 is installed on the surface of the bevel 5. A threaded collar 8 is sleeved on the periphery of the main joint 1, and the threaded collar 8 is threadedly connected to the outer wall of the main joint 1. A fixing ring 9 is sleeved on the periphery of the sub-joint 2. A pair of bolts 16 are symmetrically inserted into the side wall of the fixing ring 9, and one end of the bolt 16 is threadedly connected to the surface of the threaded collar 8. Through the cooperation of the limit ring 3 and the groove 4, when the limit ring 3 is inserted into the groove 4, the sealing gasket 7 on the bevel 5 of the main joint 1 closely fits the beveled surface 6 of the sub-joint 2. Since the front end of the limit ring 3 abuts against the bottom of the groove 4, the sealing gasket 7 will not be excessively deformed, thereby enabling the sealing gasket 7 to achieve the best sealing effect and improving the durability of the sealing gasket 7 at the same time. Through the cooperation of the threaded collar 8 with the threads on the surfaces of the main joint 1 and the sub-joint 2, the main joint 1 and the sub-joint 2 are fixed. By using the bolts 16 to fix the fixing ring 9 and the threaded collar 8, it is possible to prevent the threaded collar 8 from loosening and falling off due to the shaking of the pipeline, which affects the sealing effect, and further avoid the occurrence of liquid leakage.

[0029] Wherein, anti-slip rings 10 are provided on the outer walls of the main joint 1 and the sub-joint 2. The anti-slip rings 10 cause the inner walls of the connected pipelines to deform, making the pipelines not easy to fall off, and at the same time having a good sealing effect.

[0030] Wherein, threads are provided on the outer walls of both the main joint 1 and the sub-joint 2, and the two sections of threads are continuous. The main joint 1 and the sub-joint 2 are fixed through the cooperation of the threads and the threaded collar 8.

[0031] Wherein, a limit block 11 is provided on the outer wall of the limit ring 3, and a sliding groove 12 is opened on the inner wall of the groove 4. Through the cooperation of the limit block 11 and the sliding groove 12, when the threaded collar 8 is rotated, the main joint 1 and the sub-joint 2 are prevented from rotating, and the beveled surface 6 is prevented from rotating and rubbing the sealing gasket 7, causing the sealing gasket 7 to be worn.

[0032] Wherein, a pair of threaded holes 13 are provided on the side wall of the threaded collar 8, and a pair of binding holes 14 are opened on the side wall of the fixing ring 9, which is convenient for fixing the fixing ring 9 and the threaded collar 8 through the bolts 16.

[0033] Wherein, a rubber gasket 15 is provided on the inner wall of the fixing ring 9. Through the rubber gasket 15, the friction between the fixing ring 9 and the side wall of the sub-joint 2 is increased, and at the same time, it has a certain shock-absorbing effect, avoiding the fixing ring 9 from rotating due to vibration and affecting the fixing effect on the threaded collar 8.

[0034] Wherein, stoppers 17 are provided on the outer walls of a pair of the bolts 16, and the bolts 16 always penetrate through the beam holes 14 of the fixing ring 9 through the stoppers 17, preventing inconvenience caused by the dropping or loss of the bolts 16.

[0035] Specific usage mode and function of this embodiment:

[0036] The staff first checks the integrity of this joint. After checking and finding no problems, the staff aligns the limit ring 3 of the main joint 1 with the groove 4 of the sub-joint 2. After rotating the main joint 1 so that the limit block 11 on the limit ring 3 aligns with the sliding groove 12, the limit ring 3 is inserted into the groove 4. Subsequently, the staff holds the sub-joint 2 and rotates the threaded sleeve ring 8 at the same time. At this time, due to the effect of the limit block 11, when the threaded sleeve ring 8 is rotated, the main joint 1 will not spin. The staff rotates the threaded sleeve ring 8 until it cannot be rotated anymore. Then, the staff adjusts the fixing ring 9 on one side to align the beam hole 14 on the fixing ring 9 with the threaded hole 13, and then fixes the fixing ring 9 and the threaded sleeve ring 8 through the bolts 16. Thus, the connection of the hydraulic pipe fitting joint is completed. Through the cooperation of the above-mentioned various components, this pipe fitting joint can effectively control the deformation degree of the sealing gasket 7, improve the durability of the sealing gasket 7, and the inner and outer two groups of sealing gaskets 7 seal simultaneously, improving the sealing reliability of this pipe fitting joint. At the same time, this pipe fitting joint has a dual reinforcement method, thereby preventing the joint from falling off and further avoiding the occurrence of liquid leakage.

[0037] The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
