[0012] Beneficial effects

[0013] This utility model provides a pull-type modified plastic valve. It has the following beneficial effects:

[0014] 1. This is a pull-type modified plastic valve. During use, when it is necessary to separate the movable sealing plate and the sealing baffle, the transmission worm gear is rotated in the forward direction, the transmission worm wheel starts to rotate in the forward direction, the connecting rod starts to rotate in the forward direction with the transmission gear, the connecting rack moves upward along the inside of the connecting sleeve, and the movable sealing plate starts to move upward until the vertical end of the movable sealing plate leaves the position between the two sets of sealing baffles. Due to the self-locking principle between the transmission worm gear and the transmission worm wheel, there is no need to manually position the connecting rack, which facilitates the use of the device.

[0015] 2. This is a pull-type modified plastic valve. During use, water is discharged into the valve body through the inlet pipe and discharged through the outlet pipe. By rotating the auxiliary wheel, the transmission worm gear starts to rotate under the limiting action of the connecting block and the connecting groove. After the operation is completed, the auxiliary wheel can be pushed backward, and the connecting block will move along the inside of the connecting groove to the inside of the limiting connecting groove. At this time, the connecting block loses the limiting action of the connecting groove, thereby rotating the auxiliary wheel so that the transmission worm gear cannot rotate, which plays a role in preventing misoperation.

A matching movable sealing plate 3 is movably installed inside the valve body 1. The movable sealing plate 3 is T-shaped. Two sets of sealing baffles 4 are fixedly installed on the bottom wall of the valve body 1 cavity. The vertical end of the movable sealing plate 3 is matched with the distance between the two sets of sealing baffles 4. The vertical end of the movable sealing plate 3 is movably engaged between the two sets of sealing baffles 4. An installation frame 2 is fixedly installed on the upper side wall of the valve body 1. A connecting sleeve 5, penetrating the top wall of the valve body 1, is sealingly connected to it. A matching connecting rack 6 is movably installed inside the connecting sleeve 5. The connecting rack 6 is fixedly installed on the upper side wall of the movable sealing plate 3. A transmission tooth groove is opened on the front side wall of the connecting rack 6. A horizontally positioned connecting rod 7 is rotatably installed inside the mounting frame 2. A transmission gear 8 is fixedly installed on the outer wall of the connecting rod 7. The transmission gear 8 and the transmission tooth groove of the connecting rack 6 are meshed together. A self-locking mechanism is provided on the connecting rod 7 to restrict its rotation. The self-locking mechanism includes a transmission worm 9 and a transmission worm wheel 10. The transmission worm 9 and the transmission worm wheel 10 are meshed together. The transmission worm wheel 10 is located on the outer wall of the connecting rod 7.

[0021] In the process of using this utility model, when it is necessary to separate the movable sealing plate 3 and the sealing baffle 4, the transmission worm 9 is rotated in the forward direction, the transmission worm wheel 10 starts to rotate in the forward direction, the connecting rod 7 starts to rotate in the forward direction with the transmission gear 8, the connecting rack 6 will move upward along the inside of the connecting sleeve 5, and the movable sealing plate 3 will start to move upward until the vertical end of the movable sealing plate 3 leaves the position between the two sets of sealing baffles 4. Due to the self-locking principle between the transmission worm 9 and the transmission worm wheel 10, it is not necessary to manually position the connecting rack 6.

[0022] Example 2: Based on Example 1, as follows Figure 2 and Figure 3 As shown, the transmission worm gear 10 is fixedly installed on the outer wall of the connecting rod 7. The transmission worm gear 10 is located to the right of the transmission gear 8. The transmission worm 9 is horizontally mounted on the rear wall of the mounting frame 2 cavity. The transmission worm 9 is located above the transmission worm gear 10.

[0023] The outer wall of the transmission worm 9 extends through the front wall of the mounting frame 2. A matching connecting collar 11 is provided on the outer wall of the transmission worm 9. An auxiliary rotating wheel 12 is fixedly installed on the outer wall of the connecting collar 11 to facilitate the rotation of the transmission worm 9.

[0026] The inlet pipe 16 is horizontally and sealed to the left side wall of the valve body 1, and the outlet pipe 17 is horizontally and sealed to the right side wall of the valve body 1.

[0027] During use, water is discharged into the valve body 1 through the inlet pipe 16 and discharged from the valve body 1 through the outlet pipe 17. By rotating the auxiliary rotating wheel 12, the transmission worm 9 starts to rotate under the limiting action of the connecting block 13 and the connecting groove 14. After the operation is completed, the auxiliary rotating wheel 12 can be pushed backward, and the connecting block 13 will move along the inside of the connecting groove 14 to the inside of the limiting connecting groove 15. At this time, the connecting block 13 loses the limiting action of the connecting groove 14, thereby rotating the auxiliary rotating wheel 12 so that the transmission worm 9 cannot rotate.
