Description

Technical Field

[0001] This invention belongs to the field of connectors and relates to trimming technology, specifically a trimming device for a tee connector. Background Technology

[0002] A tee connector is a type of pipe connector, typically consisting of a main pipe and two branch pipes, commonly used to split fluid or gas from one pipe to two other pipes. It is widely used in industry, construction, agriculture, and other fields, with common types including T-type and Y-type connectors.

[0003] In existing technologies, problems such as loose connections or leakage may occur during use. To ensure the normal use of connectors, when leakage occurs between the tee connector and the branch pipe, the connection between the tee connector and the branch pipe is usually cut off. After cutting off, the tee connector and the branch pipe are separated from each other, and a new tee connector is installed before the multiple branch pipes are fixed together. The entire repair process is time-consuming, inconvenient for subsequent maintenance and replacement, and also increases the wear and tear on the tee connector. Therefore, it is necessary to use tee connector repair equipment to repair it. Summary of the Invention

[0004] The purpose of this application is to provide a repair device for a tee connector, which solves the problem that when leakage occurs between the tee connector and the branch pipe, it is inconvenient to carry out subsequent maintenance and replacement by disassembling the tee connector or cutting off the branch pipe.

[0005] To achieve the above objectives, this application provides a trimming device for a tee connector, comprising a housing, with a screw pan threaded to each end of the housing, and a limiting shell rotatably connected to the outward-facing end of each screw pan. An end block is provided at each end of the housing, and a limiting groove is formed inside the end block. A limiting strip is fixedly connected to the inner wall of each limiting groove. A limiting frame corresponding to the limiting strip is fixedly connected to the inner wall of the limiting shell. The limiting strip and the limiting frame are mutually compatible. A rubber pad is provided on the inner wall of the end block, and flanges are provided at both ends of the inner wall of the end block. The two ends of the rubber pad are engaged with the flanges. Multiple arc grooves are formed on the rubber pad. The inner wall of the limiting groove is inclined. The limiting frame includes a fixed section, a deformable section, and a plug-in section fixedly connected to each other. One end of the fixed section is fixedly connected to the inner wall of the limiting shell, and the plug-in section is plugged into the limiting strip.

[0006] Preferably, there are multiple limiting grooves, which are evenly distributed about the axis of the end block.

[0007] Preferably, the deformed segment is arc-shaped.

[0008] Preferably, the cross-sections of the fixed section, the deformable section, and the plug-in section are arc-shaped.

[0009] Preferably, a plurality of positioning strips are fixedly connected to the outer side wall of the rubber pad, the positioning strips are evenly arranged on both sides of the arc groove, and a slot is provided on the inner side wall of the end block for storing the positioning strips.

[0010] Preferably, the outer wall of the plug segment is provided with a wave block, which is adapted to the positioning strip.

[0011] Preferably, the outer sidewall of the end block is provided with a plurality of sliding grooves, and the inner sidewall of the limiting shell is fixedly connected with a slider corresponding to the sliding groove, and the slider is slidably connected to the sliding groove.

[0012] Preferably, both ends of the end block are provided with pressing grooves that communicate with the sliding groove, and each pressing groove is provided with a squeezing block, one end of which extends out of the inner wall of the end block.

[0013] Preferably, the pressing groove has a support groove at the end facing the rubber pad, and the pressing block has a secondary pressing block in the support groove.

[0014] Preferably, the end of the extrusion block facing the groove is arc-shaped, and both ends of the slider are provided with arc-shaped grooves that are adapted to the end of the extrusion block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] By setting up end blocks, limit strips, and limit frames, the limit frames include fixed sections, deformation sections, and plug-in sections that are fixedly connected to each other. After turning the screw pan, the limit shell drives the plug-in section to fit into the limit strip. The inclined limit groove drives the wave block to squeeze the positioning strip, causing the rubber pad to deform and pressing the branch pipe in the middle of the end block to better fill the sealing gap. At the same time, the two ends of the end block are provided with flanges, and the two ends of the rubber pad are stuck at the flanges. The arc groove helps the rubber pad to deform and expand. By adjusting the position of the screw pan and the limit shell, the operator can pull out the branch pipe to observe the rubber pad inside the entire end block, thereby adjusting or replacing the entire rubber pad. This makes it easier to adjust and disassemble the rubber pad. The whole process is simple and convenient to install, and also reduces the replacement frequency of the tee connector.

[0017] By setting up a slider, an extrusion block, and a secondary pressure block, the movement of the screw pan and the limiting shell drives the slider to move back and forth along the slide groove. After the slider moves, it extrudes the extrusion block at one end facing outward. After being pressed, the extrusion block extrudes the other end toward the side wall of the branch pipe, thereby increasing the pressure on the branch pipe and further increasing stability. At the same time, the secondary pressure block also presses the end of the rubber pad, thereby increasing the clamping force of the rubber pad. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please refer to the details. Figures 1-3As shown, a trimming device for a tee connector includes a housing 1. Each end of the housing 1 is threadedly connected to a screw pan 2. The outward-facing end of each screw pan 2 is rotatably connected to a limiting shell 3. An end block 4 is provided at each end of the housing 1. Multiple limiting grooves 7 are formed inside the end block 4 and are evenly distributed about the axis of the end block 4. Limiting strips 5 are fixedly connected to the inner walls of each limiting groove 4. Limiting frames 8, corresponding to the limiting strips 5, are fixedly connected to the inner walls of the limiting shell 3. The limiting strips 5 and the limiting frames 8 are mutually compatible. A rubber pad 6 is provided on the inner wall of the end block 4. Flanges are provided at both ends of the inner wall of the end block 4. The two ends of the rubber pad 6 are engaged with the flanges. Multiple arc grooves 19 are formed on the rubber pad 6 to facilitate... The rubber pad 6 expands and contracts due to deformation, making it easy to clamp both ends of the rubber pad 6 onto the flanges on both sides of the end block 4 for easy assembly and disassembly. The inner wall of the limiting groove 7 is inclined. When the operator inserts the branch pipe into one end of the tee connector, the operator turns the turning plate 2. The turning plate 2 moves slowly along the axis of the outer shell 1. The movement of the turning plate 2 causes the limiting shell 3 to move outward. Because the turning plate 2 and the limiting shell 3 are rotatably connected, the limiting shell 3 does not rotate relative to the turning plate 2 until the limiting frame 8 slowly extends into the end of the limiting strip 5. As the limiting frame 8 extends into the inclined end block 4, the limiting frame 8 gradually squeezes the rubber pad 6, thereby causing the rubber pad 6 to press tightly against the outer wall of the inserted branch pipe, increasing the sealing effect.

[0030] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 7 As shown, the limiting frame 8 includes a fixed section 14, a deformable section 15, and a plug-in section 16 that are fixedly connected to each other. One end of the fixed section 14 is fixedly connected to the inner wall of the limiting shell 3. The deformable section 15 is arc-shaped. The plug-in section 16 is plugged into the limiting strip 5. When the plug-in section 16 slowly moves in along the limiting strip 5, the plug-in section 16 is offset due to the inclined surface of the limiting groove 7. The deformable section 15 is used to increase the deformation of the plug-in section 16, so as to cause the plug-in section 16 to reset. The cross-sections of the fixed section 14, the deformable section 15, and the plug-in section 16 are arc-shaped, which is used to increase the structural strength of the entire fixed section 14, the deformable section 15, and the plug-in section 16 and increase stability.

[0031] As one implementation method in this embodiment, such as Figures 2-4 , Figure 7 and Figure 8As shown, multiple positioning strips 18 are fixedly connected to the outer wall of the rubber pad 6. The positioning strips 18 are evenly arranged on both sides of the arc groove 19. The inner wall of the end block 4 is provided with a slot 9, which is used to store the positioning strips 18. When the positioning strips 18 are located in the slot 9, the positioning strips 18 limit the entire rubber pad 6, preventing friction between the branch pipe and the rubber pad 6 when the branch pipe extends into the middle of the end block 4, which would cause the rubber pad 6 to shift along the axis of the outer shell 1, thereby causing the rubber pad 6 to fall off and affecting the installation of the branch pipe. The outer wall of the insertion section 16 is provided with a corrugated block 17, which is adapted to the positioning strips 18. When the insertion section 16 slowly extends along the limiting strip 5, the corrugated block 17 slowly presses against the positioning strip 18. After the positioning strip 18 is squeezed, the rubber pad 6 is pressed towards the branch pipe, which reduces the inner diameter of the rubber pad 6 and increases the outer diameter, which can better fill the sealing gap and thus increase the sealing effect.

[0032] As one implementation method in this embodiment, such as Figures 3-7As shown, multiple sliding grooves 10 are evenly provided on the outer side wall of the end block 4. A slider 11 corresponding to the sliding groove 10 is fixedly connected to the inner side wall of the limiting shell 3. The slider 11 is slidably connected to the sliding groove 10. When the operator turns the rotating disc 2, the limiting shell 3 moves along the sliding groove 10 through the slider 11, thereby preventing the limiting shell 3 from rotating when the rotating disc 2 rotates and increasing the stability of the limiting shell 3 during the movement process. Both ends of the end block 4 are provided with pressing grooves 20 that communicate with the sliding groove 10. Each pressing groove 20 is provided with a pressing block 12 inside. One end of the pressing block 12 extends out of the inner side wall of the end block 4. When the limiting shell 3 moves with the rotating disc 2, the limiting shell 3 drives the slider 11 to move along the sliding groove 10. After the slider 11 moves, it presses against the outward-facing end. The extrusion block 12 is used to press the rubber pad 6. After being pressed, the other end of the extrusion block 12 is pressed against the side wall of the branch pipe, thereby increasing the pressure on the branch pipe and further increasing stability. The pressing groove 20 is provided with a support groove at the end corresponding to the rubber pad 6. The extrusion block 12 is provided with a secondary pressure block 13 in the support groove. When the end of the extrusion block 12 is pressed, the end of the extrusion block 12 presses against the branch pipe in the middle of the end block 4, and the secondary pressure block 13 also presses against the end of the rubber pad 6, thereby increasing the clamping force of the rubber pad 6. The end of the extrusion block 12 facing the slide groove 10 is arc-shaped. Both ends of the slider 11 are provided with arc-shaped grooves that match the end of the extrusion block 12 to increase the fit. When the operator needs to adjust the relationship between the outer shell 1 and the branch pipe, they only need to turn the screw plate 2 in the opposite direction. The disc 2 drives the limiting shell 3 to move inward along the axis of the outer shell 1. The limiting shell 3 drives the slider 11 to slide along the slide groove 10. When the slider 11 separates from the outer pressing block 12, the outer pressing block 12 no longer presses on the branch pipe. At the same time, the insertion section 16 slowly slides out along the limiting strip 5. The pressure of the wave block 17 on the positioning strip 18 gradually decreases until the insertion section 16 moves out of the limiting strip 5. The rubber pad 6 is no longer under pressure. At this time, the branch pipe can be pulled out from the middle of the end block 4. The operator can observe the condition of the rubber pad 6 at any time and adjust the position of the rubber pad 6 in time. When the slider 11 presses on the innermost pressing block 12, the inner pressing block 12 is pressed and tightens the inward end of the rubber pad 6, thereby increasing the pressure on the inward end of the rubber pad 6. The end clamping effect prevents it from falling off. If the rubber gasket 6 is damaged or aged and cannot achieve a sealing effect, the operator can turn the screw plate 2 again, so that the limiting shell 3 moves the plug section 16 and the corrugated block 17 to the middle of the limiting strip 5, causing the middle of the rubber gasket 6 to bend inward, making it easier for the operator to remove the rubber gasket 6. After resetting the plug section 16 and the corrugated block 17, the new rubber gasket 6 is slowly installed on the flange of the end block 4. Since the arc groove 19 in the middle of the rubber gasket 6 can deform, the rubber gasket 6 is bent so that both ends are clamped onto the flange of the end block 4. The whole process is easy to disassemble and replace, improving the efficiency of replacement. At this time, the branch pipe and the end block 4 can be fixed together again without cutting and reinstalling, improving the efficiency of maintenance.

[0033] The working principle of this invention is as follows: In use, the operator first inserts the branch pipes sequentially into the middle of the corresponding end blocks 4, and then turns the screw plate 2. The screw plate 2 drives the limiting shell 3 to move, and the limiting shell 3 drives the plug section 16 to slowly fit into the limiting strip 5. The inclined setting of the inner wall of the limiting groove 7 causes the plug section 16 and the corrugated block 17 to tilt. The corrugated block 17 squeezes the positioning strip 18, causing the rubber pad 6 to deform and press against the branch pipe in the middle of the end block 4. The inner diameter of the rubber pad 6 decreases and the outer diameter increases, better filling the sealing gap and increasing the sealing effect. At the same time, when the limiting shell 3 moves, the slider 11 moves along the direction of the slide groove 10 to prevent the limiting shell 3 from rotating. After the slider 11 moves outward, it squeezes the outer extrusion block 12, causing the outer extrusion block 12 to press against the side wall of the rubber pad 6 and the branch pipe, thereby achieving the positioning effect and realizing the installation.

[0034] When the staff needs to repair the entire device, by reversing the turning plate 2, the turning plate 2 drives the limiting shell 3 to move inward along the axis of the outer shell 1. The limiting shell 3 drives the slider 11 to slide along the slide groove 10. The slider 11 no longer squeezes the outer pressing block 12. At the same time, the plug section 16 gradually moves away from the limiting strip 5 until the plug section 16 moves out of the limiting strip 5. The rubber pad 6 is no longer under pressure, and the slider 11 does not contact the inner pressing block 12. At this time, the staff can pull out the branch pipe to observe the rubber pad 6 in the entire end block 4. If the rubber pad 6 can continue to be used, the position of the rubber pad 6 can be adjusted to repair the end of the entire device. If the rubber pad 6 is damaged and can no longer be used, the staff can adjust the position of the plug section 16 and the corrugated block 17 to replace the entire rubber pad 6. After replacement, the branch pipe is installed. The whole process is simple and convenient, and also reduces the replacement frequency of the tee connector.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
