Description

Technical Field

[0001] The present application belongs to the field of joint technology, and specifically relates to a rust-proof straight-through joint. Background Art

[0002] A straight-through joint is a connecting pipe fitting in a piping system. A straight-through joint consists of joints at both ends and a hexagonal bolt disposed between the two joints. Usually, the two joints and the hexagonal bolt are integrally formed.

[0003] The straight-through joint is the conversion hub in the entire pipeline system and occupies an important position in the pipeline system. With the development of science and technology, the usage rate of straight-through joints in industry and life has gradually increased. The straight-through joint solves the transfer problem caused by short pipelines.

[0004] However, when liquid is input into the pipeline, some impurities will enter, and some larger impurities may be stuck inside the straight-through joint, which is inconvenient to clean. If you want to restore the straight-through joint to normal flow, you need to unscrew the straight-through joint to clear it and then screw it back into the pipeline. This operation is very complicated, and repeated twisting will cause wear of the threads on the joint, affecting the sealing effect and even the quality of the entire straight-through joint, reducing its service life. Utility Model Content

[0005] The purpose of this application is to solve the above-mentioned problem that when liquid is input into the pipeline, some impurities will enter, and some impurities with larger particles may be stuck inside the straight-through joint, which is inconvenient to clean. If the straight-through joint is to be restored to normal flow, it is necessary to unscrew the straight-through joint to clear it and then screw it back into the pipeline. Such operation is very complicated, and repeated twisting causes wear of the threads on the joint, affecting the sealing effect and even the quality of the entire straight-through joint, reducing its service life. A rust-proof straight-through joint is provided.

[0006] The technical solution adopted in this application is as follows: a rust-proof straight-through joint, including a straight-through joint body, both ends of the straight-through joint body are provided with external threaded connectors, the outer surface of the external threaded connector is threadedly connected to a connecting sleeve, a through cavity is opened inside the straight-through joint body, a mounting block is inserted into the upper surface of the straight-through joint body, an adsorption filter is provided at the lower end of the mounting block, and a knob is rotatably connected to the upper surface of the mounting block.

[0007] By adopting the above technical solution and the above design, the adsorption filter can adsorb and intercept impurities in the liquid to prevent them from clogging the pipeline. There is no need to frequently disassemble and clean the straight-through joint body, thereby ensuring the quality of the straight-through joint body and extending its service life.

[0008] In a preferred embodiment, a return spring is installed on one side of the inner part of the upper end of the straight-through joint body, a connecting block is provided at one end of the return spring, and limiting oblique insertion blocks are provided on both sides of the connecting block. A limiting slot corresponding to the limiting oblique insertion block is provided inside the mounting block, and a plurality of tooth blocks are provided on the surface of the limiting oblique insertion block on one side, and a gear corresponding to the tooth block is provided at the lower end of the knob, and the gear is meshed with the tooth block.

[0009] By adopting the above technical solution, the connecting block is pushed under the elastic force of the return spring so that the limiting oblique insertion block is inserted into the inside of the limiting slot, and the mounting block is limited and fixed. If the mounting block needs to be disassembled, the knob is rotated to make the gear drive the gear block, thereby moving the limiting oblique insertion block out of the inside of the limiting slot, and then the mounting block can be taken out, which is convenient for cleaning the adsorption filter. When installing the mounting block, the mounting block is inserted into the inside of the straight-through joint body. Due to the inclined surface of the limiting oblique insertion block, the mounting block pushes the limiting oblique insertion block, so that the adsorption filter can be installed, thereby improving convenience and stability.

[0010] In a preferred embodiment, slots are provided on both sides of the outer surfaces of the through connector body, and an insert corresponding to the slots is provided on one side surface of the connecting sleeve.

[0011] By adopting the above technical solution, the plug block is inserted into the interior of the slot, thereby improving the stability of the connection between the connecting sleeve and the straight-through connector body.

[0012] In a preferred embodiment, a sealing gasket is adhered to the outer surface of the insert.

[0013] By adopting the above technical solution, the friction between the plug block and the slot is increased by the sealing gasket, thereby improving the stability of the connection between the connecting sleeve and the straight-through connector body, and also improving the sealing performance.

[0014] In a preferred embodiment, the straight-through connector body is made of 304 stainless steel.

[0015] By adopting the above technical solution, it is expected to have good anti-oxidation and anti-corrosion capabilities, reduce the possibility of rusting of the straight-through joint body, and extend its service life.

[0016] In a preferred embodiment, the outer surface of the through connector body is sprayed with epoxy anti-rust paint.

[0017] By adopting the above technical solution, it has good chemical resistance and adhesion, can effectively isolate the metal surface from oxygen and moisture in the environment, reduce the occurrence of oxidation and corrosion, and extend the service life of the straight-through joint body.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] 1. The adsorption filter can absorb and intercept impurities in the liquid to prevent them from clogging the pipeline. There is no need to frequently disassemble and clean the straight-through joint body, which ensures the quality of the straight-through joint body and extends its service life.

[0020] 2. Under the elastic force of the reset spring, push the connecting block so that the limiting oblique insertion block is inserted into the inside of the limiting slot to limit and fix the mounting block. If the mounting block needs to be disassembled, rotate the knob to make the gear drive the tooth block, thereby moving the limiting oblique insertion block out of the inside of the limiting slot, and then the mounting block can be taken out, improving convenience and stability.

[0027] Reference Figure 1-4A rust-proof straight-through joint comprises a straight-through joint body 1, with externally threaded connectors 6 provided at both ends of the straight-through joint body 1, a connecting sleeve 5 being threadedly connected to the outer surface of the externally threaded connector 6, a through cavity 14 being opened inside the straight-through joint body 1, a mounting block 2 being inserted into the upper surface of the straight-through joint body 1, an adsorption filter screen 8 being provided at the lower end of the mounting block 2, and a knob 4 being rotatably connected to the upper surface of the mounting block 2. Through the above design, the adsorption filter screen 8 can adsorb and intercept impurities in the liquid to prevent them from clogging the pipeline. There is no need to frequently disassemble and clean the straight-through joint body 1, thereby ensuring the quality of the straight-through joint body 1 and extending its service life.

[0028] Reference Figure 2-4 A return spring 10 is installed on one side of the upper end of the straight-through connector body 1, and a connecting block 11 is provided at one end of the return spring 10. Limited oblique insertion blocks 12 are provided on both sides of the connecting block 11. A limiting slot corresponding to the limiting oblique insertion block 12 is opened inside the mounting block 2. A plurality of tooth blocks 9 are provided on the surface of the limiting oblique insertion block 12 on one side. A gear 13 corresponding to the tooth block 9 is provided at the lower end of the knob 4. The gear 13 is engaged with the tooth block 9. Under the elastic force of the return spring 10, the connecting block 11 is pushed so that the limiting oblique insertion block 12 is inserted into the limiting slot. Inside, the mounting block 2 is limited and fixed. If the mounting block 2 needs to be disassembled, the knob 4 is rotated to make the gear 13 drive the tooth block 9, so that the limiting oblique insertion block 12 is moved out of the limiting slot, and then the mounting block 2 can be taken out, which is convenient for cleaning the adsorption filter 8. When installing the mounting block 2, the mounting block 2 is inserted into the interior of the straight-through joint body 1. Due to the inclined surface of the limiting oblique insertion block 12, the mounting block 2 pushes the limiting oblique insertion block 12, so that the adsorption filter 8 can be installed, thereby improving convenience and stability.

[0029] Reference Figure 1 and Figure 4 Slots 7 are provided on the outer surfaces of both sides of the straight-through connector body 1, and an insert block 3 corresponding to the slot 7 is provided on one side surface of the connecting sleeve 5. The insert block 3 is inserted into the inside of the slot 7 to improve the stability of the connection between the connecting sleeve 5 and the straight-through connector body 1.

[0030] Reference Figure 4 A sealing gasket is pasted on the outer surface of the plug block 3, which increases the friction between the plug block 3 and the slot 7, improves the stability of the connection between the connecting sleeve 5 and the straight-through connector body 1, and also improves the sealing performance.

[0031] Reference Figure 1-4 The material of the straight-through connector body 1 is 304 stainless steel, which has good anti-oxidation and anti-corrosion capabilities, reduces the possibility of rusting of the straight-through connector body 1, and prolongs its service life.

[0032] Reference Figure 1-4 The outer surface of the straight-through joint body 1 is sprayed with epoxy anti-rust paint, which has good chemical resistance and adhesion, can effectively isolate the metal surface from oxygen and moisture in the environment, reduce the occurrence of oxidation and corrosion, and extend the service life of the straight-through joint body 1.

[0033] The implementation principle of the rust-proof straight-through joint embodiment of the present application is:

[0034] When installing, the pipe is connected through the external threaded connector 6, and then the connecting sleeve 5 is threadedly connected to the outer surface of the external threaded connector 6 to fix the connection of the pipe, and then the plug block 3 is rotated into the inside of the slot 7 to fix it. Under the elastic force of the return spring 10, the connecting block 11 is pushed to make the limiting oblique insertion block 12 inserted into the inside of the limiting slot to limit and fix the mounting block 2. If it is necessary to disassemble the mounting block 2, the knob 4 is rotated to make the gear 13 drive the gear block 9, thereby making the limiting oblique insertion block 12 move out of the inside of the limiting slot, and then the mounting block 2 can be taken out, which is convenient for cleaning the adsorption filter 8. When installing the mounting block 2, the mounting block 2 is inserted into the inside of the straight-through joint body 1. Due to the inclined surface of the limiting oblique insertion block 12, the mounting block 2 pushes the limiting oblique insertion block 12, so that the adsorption filter 8 can be installed, thereby improving convenience and stability.
