Description
Technical Field
[0001] This utility model relates to the field of anti-clogging device for the inspection port of a drain pipe tee. Background Technology
[0002] Drain tees are primarily used to connect multiple main drainage pipes, ensuring the smooth operation of the household drainage system. However, during use, main drainage pipes may become clogged for various reasons. The most common cause is the accumulation of hair and water-insoluble lumps within the pipes. Currently, unclogging requires hiring professionals and specialized machinery, which is not only troublesome but also expensive.
[0003] Therefore, we have made improvements and proposed an anti-clogging device for the inspection port of the drain pipe tee. Summary of the Invention
[0004] To address the problems raised by the present invention, the present invention provides the following technical solution:
[0005] A clog-prevention device for the access port of a drain pipe tee is provided to improve the above-mentioned problems.
[0006] The present invention is as follows:
[0007] The device includes an anti-clogging grate, with a first base integrally formed at the bottom and a second base integrally formed at the bottom. Both sides of the anti-clogging grate have blocking mechanisms at their top ends. The outer walls of both the first and second bases have arc-shaped support plates. The first base has a first unthreaded through hole, and the second base has a second unthreaded through hole. A threaded sleeve is embedded in the left side wall of the second unthreaded through hole, and an adjusting screw mechanism is installed inside the threaded sleeve.
[0008] As a preferred technical solution of this utility model, the blocking mechanism includes a long movable rocker arm and a rotating ring, wherein the rotating ring is integrally formed at the end of the long movable rocker arm.
[0009] As a preferred technical solution of this utility model, the top of both sides of the anti-blocking grate is integrally formed with a rotating shaft, and the long movable rocker arm is rotatably connected to the rotating shaft through a rotating ring.
[0010] As a preferred technical solution of this utility model, the adjusting screw mechanism includes an adjusting screw, one end of which is threadedly connected to a threaded sleeve, and the other end of which is movably connected to a first unthreaded through hole.
[0011] As a preferred technical solution of this utility model, the rear end of the inner sidewall of the arc-shaped support piece is integrally formed with a positioning rod, and the front end of the inner sidewall of the arc-shaped support piece is integrally formed with a positioning retaining shaft.
[0012] As a preferred technical solution of this utility model, both the outer side wall of the first base and the outer side wall of the second base are provided with slot holes, and the positioning rod matches the slot holes.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In the solution of this utility model:
[0015] 1. By inserting this device into the maintenance pipe through the inspection port, and then rotating the adjusting screw, the adjusting screw moves to the right as it rotates. When it moves to the right and touches the right-side arc-shaped support plate, it drives the right-side arc-shaped support plate, making the left-side arc-shaped support plate tightly fit against the inner wall of the pipe. Then continue to rotate the adjusting screw in the same direction. Since the right end of the adjusting screw is already pressed against the inner wall of the tee inspection port and cannot move, continue to rotate the adjusting screw in the same direction. The adjusting screw will drive the anti-clogging grate, the first base, and the arc-shaped support plate to the right through the threaded sleeve. When the threaded sleeve moves to the right and touches the right-side arc-shaped support plate, it drives the right-side arc-shaped support plate, making the left-side arc-shaped support plate tightly fit against the inner wall of the pipe at the inspection port, thus locking the device inside the pipe opening.
[0016] 2. By inserting the adjusting screw into the first unthreaded through hole, the threaded end of the adjusting screw is first inserted and then threaded into the threaded sleeve to be adjusted to the center position; then, the two arc-shaped support plates are respectively inserted into the outer walls of the first base and the second base; finally, the two long movable rocker arms are installed on the two side walls of the anti-blocking grate, and the device is assembled. This achieves a simple structure, convenient assembly, and low operating cost. Attached Figure Description

[0028] like Figure 1-4As shown, this embodiment proposes an anti-clogging device for the inspection port of a drain pipe tee, including an anti-clogging grate 1, which intercepts debris. A first base 2 is integrally formed at the bottom of the anti-clogging grate 1, and a second base 3 is also integrally formed at the bottom of the anti-clogging grate 1. Blocking mechanisms are provided at the top of both side walls of the anti-clogging grate 1 to intercept debris falling into the gap between the grate and the pipe. Arc-shaped support plates 4 are provided on the outer walls of both the first base 2 and the second base 3. These arc-shaped support plates 4 support the grate outwards and act as a locking mechanism. The device has the following functions: the first base 2 has a first unthreaded through hole 5, through which the adjusting screw 8 is inserted; the second base 3 has a second unthreaded through hole 6, and a threaded sleeve 7 is embedded in the left side wall of the second unthreaded through hole 6, so that the first inserted end of the adjusting screw 8 is threadedly connected to the threaded sleeve 7. When in use, this device is not only convenient to install in the maintenance pipe of the tee pipe, but also prevents debris from falling from the gap between the grate and the pipe and clogging the main drain pipe through the rotating rocker arm. This device is simple, practical and inexpensive.
[0029] The top of both sides of the anti-clogging grate 1 is equipped with a blocking mechanism (this blocking mechanism can be freely set according to actual needs; when the inner diameter of the pipe is small, there is no need to install the blocking mechanism). The blocking mechanism includes a long movable rocker arm 9 and a rotating ring 10. The rotating ring 10 is integrally formed at the end of the long movable rocker arm 9. A rotating shaft 11 is integrally formed at the top of both sides of the anti-clogging grate 1. The rotating ring 10 at the end of the long movable rocker arm 9 is fitted onto the rotating shaft 11 on both sides of the anti-clogging grate 1 (interference fit).
[0030] The adjusting screw mechanism includes an adjusting screw 8. One end of the adjusting screw 8 is threaded into the threaded sleeve 7. When the right end of the adjusting screw 8 is already pressed against the positioning rod 12 in the second unthreaded through hole 6 and cannot move, if the adjusting screw 8 is rotated, the adjusting screw 8 will drive the right arc-shaped support plate to move to the right.
[0031] The end of the adjusting screw 8 away from the threaded sleeve 7 is movably connected to the first unthreaded through hole 5.
[0032] A positioning rod 12 is integrally formed at the rear end of the inner sidewall of the arc-shaped support plate 4, and a positioning clip 13 is integrally formed at the front end of the inner sidewall of the arc-shaped support plate 4. Slot holes are opened on the outer sidewall of the first base 2 and the outer sidewall of the second base 3. The two arc-shaped support plates 4 are respectively inserted into the outer sidewall of the first base 2 and the second base 3, so that the positioning rod 12 on the arc-shaped support plate 4 is inserted into the slot hole on the outer sidewall of the base (interference fit insertion).
[0033] Specifically, when assembling the anti-clogging device for the inspection port of this drain pipe tee: insert the adjusting screw 8 into the first unthreaded through hole 5, so that the first inserted end of the adjusting screw 8 is threaded into the threaded sleeve 7, and screw the adjusting screw 8 into the centered position between the first base 2 and the second base 3; then insert the two arc-shaped support plates 4 into the outer walls of the first base 2 and the second base 3 respectively, so that the positioning rod 12 on the arc-shaped support plate 4 is inserted into the slot hole on the outer wall of the base (interference fit insertion); finally, install the two long movable rocker arms 9 on the two side walls of the anti-clogging grate 1, and fit the rotating ring 10 at the end of the long movable rocker arm 9 onto the rotating shaft 11 on the two side walls of the anti-clogging grate 1 (interference fit fitting), and the assembly of this device is completed;
[0034] During installation: First, unscrew the movable cover 01 of the inspection port 02 at the drain tee pipe inspection port. Then, hold the arc-shaped support pieces 4 on both sides of the assembled anti-clogging grate 1 with one hand and insert it into the inspection port from the horizontal center. Push the anti-clogging grate 1 horizontally inward until it contacts the inner wall of the tee inspection port 02. Next, rotate the adjusting screw 8. While rotating the adjusting screw 8, move it to the right until it abuts against the positioning rod 12 on the right arc-shaped support piece 4. This will move the right arc-shaped support piece 4, making it tightly fit against the inner wall of the pipe. Then, continue to rotate the adjusting screw 8 in the same direction. When the right end of the adjusting screw 8 is already pressed against the inner wall of the tee inspection port 02 and cannot move, continue to rotate the adjusting screw 8 in the same direction. The adjusting screw 8 will drive the anti-blocking grate 1, the first base 2 and the left arc-shaped support plate 4 to move to the left through the threaded sleeve 7, so that the left arc-shaped support plate 4 is tightly attached to the inner wall of the pipe at the inspection port, thus locking the device in the pipe opening and completing the installation. Finally, unfold the long movable rocker arm 9 to intercept the debris falling from the gap between the grate and the pipe, which can prevent the debris from falling from the gap between the grate and the pipe and blocking the main drain pipe.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
