[0003] In prior art, when fixing water inlet and outlet pipeline and another group of pipeline of washing machine, it is usually fixed in the form of fastening, but in the process of water throwing of washing machine, it will produce shaking, and with the growth of using time, the two groups of pipeline fixed are prone to loosen and appear the phenomenon of water leakage, which affects the service life of washing machine. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies of prior art, the utility model provides a water inlet and outlet clamp for washing machine, which can ensure the sealing stability of water inlet and outlet pipeline connection for a long time.

[0005] The utility model solves the above-mentioned technical problems by adopting the following technical scheme:

[0006] A water inlet and outlet clamp for washing machine, comprising a shell, a fixed groove is fixedly connected above the shell, a square groove is arranged inside the fixed groove, a worm gear is rotatably connected inside the square groove, the worm gear is meshingly connected with a worm, a connecting rod is fixedly connected to the side surface of the worm, a threaded rod for extruding a penetrating rod is arranged above the square groove, the penetrating rod is rotatably connected with a connecting block, the connecting block is fixed above the shell, a semicircular notch for sliding a sliding ring groove is formed in the side surface of the connecting block, a threaded ring is arranged inside the sliding ring groove, a threaded column on pipe is threadedly connected with the threaded ring, and the threaded column on pipe is fixed to the outer surface of the inner swallowing pipe.

[0007] The above technical scheme further comprises:

[0008] The connecting rod is rotatably connected to the fixed groove, and a turning block is fixedly connected to the end of the connecting rod away from the worm gear. The turning block is rotatably connected to the fixed groove via the connecting rod, providing the user with a convenient operating component. The user only needs to rotate the turning block to drive the worm gear through the connecting rod, thereby driving the worm wheel and moving the fixed groove and connecting block closer or further apart. This simple and labor-saving operation significantly improves the installation and adjustment efficiency of the clamp. The design of the threaded turning rod and the elliptical block allows for fine-tuning of the clamp. When a fine adjustment to the clamp's tightness is required, the user can rotate the elliptical block, causing the threaded turning rod to move within the fixed groove, thus precisely controlling the clamping force to ensure a tight fit between the clamp and the pipe, enhancing sealing performance and preventing leakage.

[0009] The threaded rod is threadedly connected to the fixed groove, and an elliptical block is fixedly connected to the end of the threaded rod away from the fixed groove.

[0010] The surface of the fixing groove has another set of semi-circular cuts for placing threaded posts on the pipe.

[0011] The outer casing has an anti-slip pleated layer inside, and the outer surface of the inner tube has multiple sets of water-repellent and leak-proof layers. The anti-slip pleated layer increases the friction between the outer casing and the pipe, making the clamp more stable after installation and less prone to slippage. The water-repellent and leak-proof layers effectively prevent water from seeping out from the connection between the inner tube and the pipe. This double protection greatly improves the sealing performance of the clamp, prevents water leakage, and protects the surrounding environment of the washing machine from water damage.

[0012] The inner ring of the worm gear is provided with an internal thread layer.

[0013] An elliptical ring track is provided inside the sliding ring groove, which is used for the sliding of the threaded ring. The cooperation between the elliptical ring track and the sliding ring groove provides a stable sliding track for the threaded ring. When the threaded column on the rotating pipe is rotated, the threaded ring can slide smoothly on the elliptical ring track, allowing the inner tube to be accurately adjusted to the center position, ensuring uniform clamping of the pipe by the clamp, improving the sealing effect, and also extending the service life of the clamp.

[0014] The bottom of the semi-circular notch is provided with a hole for the sliding ring groove to slide. This hole allows the sliding ring groove to slide smoothly at the bottom of the semi-circular notch, ensuring unimpeded movement of the threaded ring on the elliptical ring track. This facilitates flexible position adjustment of the threaded post and the inner tube during clamp installation and adjustment, improving installation efficiency and clamp performance.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The inlet and outlet clamps of this application, by rotating the screwing block, drive the connecting rod and worm gear to rotate, so that the worm wheel drives the insertion rod through the internal thread layer, so that the fixing groove and the connecting block are closely close, and the threaded column on the pipe is firmly clamped in the round hole formed by the two sets of semi-circular cuts, and the inner tube is securely fixed; at the same time, the anti-slip pleated layer inside the outer shell increases the friction with the pipe, and the water-proof leakage layer on the outer surface of the inner tube can effectively prevent water seepage.

[0017] 2. During installation, users can easily tighten the clamp by simply operating the screw block, without the need for other complicated tools, greatly reducing the installation difficulty. Furthermore, the design of the threaded screw rod and the elliptical block allows for fine adjustment of the clamping force, ensuring a perfect fit between the clamp and the pipeline. During long-term use, the self-locking characteristics of the worm gear and worm, as well as the stable guidance of the sliding ring groove and elliptical ring rail on the threaded ring, can always maintain the clamp's tightness, continuously ensuring the sealing stability of the inlet and outlet pipeline connection and preventing loosening and leakage.

[0024] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1-5As shown, a water inlet and drain clamp for a washing machine includes a housing 1. A fixing groove 5 is fixedly connected to the top of the housing 1. A square groove 7 is provided inside the fixing groove 5. A worm gear 11 is rotatably connected inside the square groove 7. A worm 10 is meshed with the worm gear 11. A connecting rod 9 is fixedly connected to the side of the worm 10. A threaded rod 13 for pressing an insert rod 20 is provided above the square groove 7. The insert rod 20 is rotatably connected to a connecting block 6. The connecting block 6 is fixed above the housing 1. A semi-circular cutout 19 for sliding a sliding ring groove 15 is provided on the side of the connecting block 6. A threaded ring 17 is provided inside the sliding ring groove 15. A threaded post 18 on the pipe is threadedly connected to the threaded ring 17. The threaded post 18 on the pipe is fixed to the outer surface of the inner tube 3.

[0026] In one embodiment, the connecting rod 9 is rotatably connected to the fixed groove 5, and a turning block 8 is fixedly connected to the end of the connecting rod 9 away from the worm gear 10.

[0027] In this embodiment, the tightening block 8 is rotatably connected to the fixed groove 5 via the connecting rod 9, providing the user with a convenient operating component. The user only needs to rotate the tightening block 8 to drive the worm gear 10 via the connecting rod 9, which in turn drives the worm wheel 11, allowing the fixed groove 5 and the connecting block 6 to move closer or further apart. This simple operation improves the efficiency of clamp installation and adjustment. The design of the threaded tightening rod 13 and the elliptical block 14 facilitates fine-tuning of the clamp. When a fine adjustment to the clamp's tightness is required, the user can rotate the elliptical block 14, causing the threaded tightening rod 13 to move within the fixed groove 5, thereby precisely controlling the clamping force of the clamp to ensure a tight fit against the pipe, enhancing sealing performance and preventing leakage.

[0028] In one embodiment, the threaded rod 13 is threadedly connected to the fixed groove 5, and an elliptical block 14 is fixedly connected to the end of the threaded rod 13 away from the fixed groove 5.

[0029] In one embodiment, the surface of the fixing groove 5 is provided with another set of semi-circular cutouts 19 for placing the threaded post 18 on the pipe.

[0030] In one embodiment, the outer shell 1 is provided with an anti-slip pleated layer 2 inside, and the outer surface of the inner tube 3 is provided with multiple sets of water-repellent and leak-proof layers 4.

[0031] In this embodiment, the anti-slip wrinkle layer 2 increases the friction between the outer shell 1 and the pipe, making the clamp more stable after installation and less prone to slippage. The water-repellent layer 4 effectively prevents water from seeping out from the connection between the inner tube 3 and the pipe, providing double protection and greatly improving the sealing performance of the clamp, preventing water leakage and protecting the surrounding environment of the washing machine from water stains.

[0032] In one embodiment, the inner ring of the worm gear 11 is provided with an internal thread layer 12.

[0033] In one embodiment, an elliptical ring rail 16 is provided inside the sliding ring groove 15, and the elliptical ring rail 16 is used for sliding the threaded ring 17.

[0034] In this embodiment, the cooperation between the elliptical ring rail 16 and the sliding ring groove 15 provides a stable sliding track for the threaded ring 17. When the threaded post 18 on the rotating pipe is rotated, the threaded ring 17 can slide smoothly on the elliptical ring rail 16, allowing the inner tube 3 to be accurately adjusted to the center position, ensuring uniform clamping of the pipe by the clamp, improving the sealing effect, and also extending the service life of the clamp.

[0035] In one embodiment, the bottom of the semicircular cut 19 is provided with a hole for the sliding annular groove 15 to slide. This hole allows the sliding annular groove 15 to slide smoothly at the bottom of the semicircular cut 19, ensuring that the movement of the threaded ring 17 on the elliptical ring track 16 is unimpeded. This design facilitates flexible positional adjustment of the threaded post 18 and the inner tube 3 during clamp installation and adjustment, improving installation efficiency and clamp performance.

[0036] The working principle of the inlet and outlet clamps for washing machines in this utility model is as follows: Whether facing the inlet or outlet pipe, a connecting pipe is needed to form a normal water connection sequence for the washing machine. Taking the outlet pipe as an example, one end of the clamp needs to be clamped onto the extended iron plate of the drain after removing the filter screen, and the other end needs to be clamped onto the drain hose of the washing machine. First, the inner tube 3 is fitted onto the extended ring pipe of the drain, completely covering the surface of the water-avoiding layer 4. Then, the drain hose of the washing machine is fitted onto the surface of the water-avoiding layer 4 at the other end of the inner tube 3. Both are fitted onto the two sets of water-avoiding layers 4 on the outer surface of the inner tube 3. Rotating the threaded post 18 on the pipe, the threaded post 18 and the threaded ring 17 rotate until the inner tube 3, fixed at the bottom of the threaded post 18, is in the center position. Manually pinching the fixing groove 5 and the connecting block 6, the inserting rod 20 is inserted into the inner ring surface of the worm gear 11 along the hole on the side of the fixing groove 5. Rotating the screw block 8 causes the connecting rod 9 to rotate, which in turn causes the worm gear 10 to mesh with the worm wheel 11. The rotation of the worm wheel 11 allows it to mesh with the insert rod 20 using the internal thread layer 12 on its inner wall, thereby bringing the fixing groove 5 and the connecting block 6 closer together. Finally, as the fixing groove 5 and the connecting block 6 approach each other, the threaded post 18 on the pipe is clamped in a circular hole formed by two sets of semi-circular cuts 19 between the fixing groove 5 and the connecting block 6. At this time, the drain extension ring pipe is squeezed by the anti-slip pleated layer 2 inside the outer shell 1 and the water-repellent leakage layer 4 on the outer surface of the inner tube 3, thereby preventing water from overflowing and sliding, and ensuring normal drainage.

[0037] At the same time, the worm gear 10 and the internal thread layer 12 have a certain self-locking function. Therefore, even if there is shaking during the washing process, the insertion rod 20 will not easily rotate as the usage time increases, and finally the threaded rod 13 will be turned to further prevent the insertion rod 20 from sliding.

[0038] Although preferred embodiments of the present invention have been shown and described, those skilled in the art can make various changes, modifications or substitutions to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
