Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, and more specifically, it relates to a durable hydraulic pipe joint. Background Art

[0002] A hydraulic pipe joint is a key component used to connect high-pressure oil pipes to high-pressure oil pipes or hydraulic components in a hydraulic system. Since the hydraulic pipe joint is used in the hydraulic system for a long time, the hydraulic pipe joint is usually used in cooperation with a sealing gasket to enhance the sealing effect at the connection.

[0003] Chinese Patent No. CN211371529U discloses a straight-through joint, and its technical key points are as follows: It includes a joint body, the joint body includes a central nut section and a first threaded pipe column and a second threaded pipe column respectively connected to both ends of the central nut section. A connecting section is provided between the central nut section and the first threaded pipe column. An elastic gasket is sleeved on the connecting section. A plurality of inserts are provided on the outer peripheral wall of the connecting section. A plurality of insertion teeth are provided on both the upper surface and the lower surface of the insert. A slot for the insert to insert and a notch for the insertion teeth to insert are provided on the inner peripheral wall of the elastic gasket. The notch communicates with the slot. Through the limitation of the insertion teeth by the limiting teeth, the elastic gasket can be firmly fixed on the connecting section. When the joint body is connected to the pipeline, even if the force is uneven, the elastic gasket will not tilt and deviate, so that the elastic gasket can be closely attached to the central nut section, thus ensuring the sealing effect of the elastic gasket.

[0004] However, after long-term use, the sealing gasket is prone to damage or aging by itself, which is likely to affect the sealing effect. Therefore, when the operator repairs the hydraulic system, the aging and damaged sealing gasket is usually replaced. Since there is a stable cooperation between the sealing gasket and the joint body of this kind of joint, it is laborious for the operator to disassemble the elastic gasket during the disassembly process, and it is inconvenient to replace. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a durable hydraulic pipe joint, which is convenient for timely replacement while ensuring the sealing effect.

[0006] The above technical purpose of the utility model is achieved by the following technical solutions: A durable hydraulic pipe joint includes a screwing section and threaded sections provided at both ends of the screwing section. Elastic gaskets can be detachably installed on both sides of the screwing section. A plurality of embedding blocks are circumferentially arranged on one side of the elastic gasket. A plurality of embedding grooves for the embedding blocks to embed are provided on the screwing section. An inner cavity communicating with the embedding grooves is provided in the screwing section. A plurality of ejecting blocks for extending into the embedding grooves and ejecting the embedding blocks out of the embedding grooves are slidably connected in the inner cavity. A driving member for driving the ejecting blocks to slide is provided in the inner cavity.

[0007] The utility model is further configured as follows: an elastic clamping block is obliquely provided on one side of the embedding block, and a clamping groove for the elastic clamping block to be clamped into is opened on the side wall of the embedding groove.

[0008] The utility model is further configured as follows: an oblique groove is provided on the elastic clamping block, and a contact piece for contacting with the side wall of the oblique groove is provided on the top of the top block.

[0009] The utility model is further configured as follows: a receiving groove for receiving the elastic card block is opened on the side wall of the insert block.

[0010] The utility model is further configured as follows: the driving member comprises a driving ring slidably connected in the inner cavity; one end of the top block away from the abutment piece is fixedly connected to the driving ring.

[0011] The utility model is further configured as follows: long grooves for connecting the inner chamber with the external environment are opened on both sides of the screwing section, and the driving member also includes adjustment blocks arranged on both sides of the driving ring and slidably connected to the long grooves.

[0012] The utility model is further configured such that: the length of the adjusting block is equal to the depth of the long slot.

[0013] The utility model is further configured as follows: the screwing section and the threaded section are both made of stainless steel.

[0014] To sum up, the utility model has the following beneficial effects: the utility model can pre-fix the elastic gasket by limiting the embedding block through the embedding groove, thereby avoiding the displacement of the elastic gasket due to uneven force when the joint is connected to the pipeline, which is beneficial to ensuring the sealing effect of the elastic gasket. At the same time, through the cooperation of the driving member and the top block, the embedding block can be quickly removed from the embedding groove, and the elastic gasket can be quickly disassembled, which ensures the sealing effect of the elastic gasket while making it convenient for the operator to replace it.

Detailed implementation manners

[0019] The following combines the accompanying drawings and embodiments to describe the present utility model in detail.

[0020] Refer to Figures 1-3 As shown, a durable hydraulic pipe joint includes a screwing section 1 and threaded sections 2 provided at both ends of the screwing section 1. Both the screwing section 1 and the threaded sections 2 are made of stainless steel material. The stainless steel material has high strength and corrosion resistance, making the overall joint relatively durable. Elastic gaskets 3 can be detachably installed on both sides of the screwing section 1. A number of embedding blocks 4 are circumferentially arranged on one side of the elastic gasket 3. A number of embedding grooves 5 for the embedding blocks 4 to be embedded are provided on the screwing section 1. An inner cavity 6 communicating with the embedding grooves 5 is provided in the screwing section 1. A number of ejector blocks 7 for extending into the embedding grooves 5 and ejecting the embedding blocks 4 from the embedding grooves 5 are slidably connected in the inner cavity 6. A driving member for driving the ejector blocks 7 to slide is provided in the inner cavity 6. When an operator uses the joint to connect pipes, the elastic gasket 3 can be first installed and fixed on the screwing section 1. The specific operation is as follows: Place the elastic gasket 3 on both sides of the screwing section 1, align the embedding blocks 4 with the embedding grooves 5 and gently press. The embedding blocks 4 will naturally be embedded in the embedding grooves 5. At this time, the ejector blocks 7 naturally contract in the inner cavity 6 and do not interfere with the embedding of the embedding blocks 4. Then, through the limitation of the embedding blocks 4 by the embedding grooves 5, the pre-fixation of the elastic gasket 3 can be achieved, thereby avoiding the offset of the elastic gasket 3 due to uneven force when the joint is connected to the pipe, which is beneficial to ensuring the sealing effect of the elastic gasket 3. When the operator needs to replace the elastic gasket 3, the driving member can be controlled to drive the ejector blocks 7 to slide towards the embedding grooves 5, so that they extend into the embedding grooves 5 and abut against the embedding blocks 4. Then, as the ejector blocks 7 continue to slide, the ejector blocks 7 apply a thrust to the embedding blocks 4 and eject them from the embedding grooves 5. After the embedding blocks 4 are completely separated from the embedding grooves 5, the limitation of the embedding blocks 4 by the embedding grooves 5 is released, and the operator can easily remove the elastic gasket 3 for replacement.

[0021] Refer to Figures 1-3As shown, an elastic clamping block 8 is inclinedly arranged on one side of the insert block 4, and a clamping groove 9 for the elastic clamping block 8 to be inserted into is formed on the side wall of the insertion groove 5. During the process of the insert block 4 being inserted into the insertion groove 5, the elastic clamping block 8 is elastically deformed under the extrusion of the side wall of the insertion groove 5. When the insert block 4 completely enters the insertion groove 5, the elastic clamping block 8 moves to the clamping groove 9. At this time, the extrusion between the elastic clamping block 8 and the side wall of the insertion groove 5 disappears, and the elastic clamping block 8 recovers its deformation and is naturally clamped into the clamping groove 9. At this time, the elastic clamping block 8 is restricted by the clamping groove 9, thereby restricting the insert block 4 from being disengaged from the insertion groove 5, ensuring the connection stability between the elastic washer 3 and the screwing section 1. An inclined groove 10 is formed on the elastic clamping block 8, and a contact piece 11 for abutting against the side wall of the inclined groove 10 is arranged on the top of the top block 7. When the elastic washer 3 is disassembled, the top block 7 is driven to extend into the insertion groove 5 by operating the driving member. As the top block 7 extends, the contact piece 11 on its top will gradually contact the side wall of the inclined groove 10 on the elastic clamping block 8. Due to the action of the inclined groove 10, the contact piece 11 will apply a thrust to the side wall of the inclined groove 10 during the continuous movement. At the same time, a component force perpendicular to the thrust direction will be generated on the inclined surface of the inclined groove 10, thereby forcing the elastic clamping block 8 to be compressed and deformed and disengaging it from the clamping groove 9, so as to facilitate the top block 7 to further push the insert block 4 out of the insertion groove 5. A receiving groove 12 for accommodating the elastic clamping block 8 is formed on the side wall of the insert block 4. During the process of the elastic clamping block 8 being extruded and deformed, the receiving groove 12 provides a receiving space for the deformed elastic clamping block 8, enabling the elastic clamping block 8 to bend into the receiving groove 12 after being extruded, thereby avoiding the extrusion of the elastic clamping block 8 between the inner side wall of the insertion groove 5 and the side wall of the insert block 4, which is beneficial to ensuring the normal use of the elastic clamping block 8.

[0022] Refer to Figure 1As shown, the driving member includes a driving ring 13 that is slidably connected to the inner chamber 6, and the end of the top block 7 away from the contact piece 11 is fixedly connected to the driving ring 13. In the process of removing the elastic gasket 3, the driving ring 13 is controlled to slide, and the driving ring 13 can stably and reliably transmit power to each top block 7, thereby driving all the top blocks 7 to move synchronously, which is conducive to ensuring that all the embedded blocks 4 are synchronously out of the embedded groove 5, making the operation of removing the elastic gasket 3 more convenient. Long grooves 14 for connecting the inner chamber 6 with the external environment are opened on both sides of the screwing section 1. The driving member also includes adjustment blocks 15 arranged on both sides of the driving ring 13 and slidably connected to the long groove 14. When disassembly or installation operations are required, The user operates the adjustment block 15 externally and applies external force to it. Under the action of the external force, the adjustment block 15 slides along the long groove 14 and transmits the force to the drive ring 13. The drive ring 13 slides in the inner chamber 6 under the action of the force, and finally realizes the movement of the top block 7. The adjustment block 15 provides a stable fulcrum for the operator, which is convenient for the operator to control the top block 7, thereby making the operation of removing the elastic gasket 3 more labor-saving, and the length of the adjustment block 15 is equal to the groove depth of the long groove 14, which enables the top surface of the adjustment block 15 to be on the same plane as the outer wall of the screwing section 1, making the outer wall of the screwing section 1 relatively flat, thereby avoiding interference with the screwing of the screwing section 1 due to the existence of the adjustment block 15.
