Description

Technical Field

[0001] The utility model belongs to the field of valves, and in particular relates to a bathtub valve which is easy to replace. Background Art

[0002] Valves are an indispensable product in the water industry, mainly used in urban, construction, enterprise water supply and drainage projects, industrial and domestic sewage treatment and water conservancy projects.

[0003] Currently, most valves are fixedly installed on drain pipes. When the valve is used for a long time, the internal parts of the valve are prone to rust. If the valve is not removed for maintenance or replacement in time, the valve will not be able to be used normally. However, valves fixed on drain pipes are prone to damage or rupture of water pipes during removal, and the removal process takes a long time, resulting in reduced practicality of the valve.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0008] The bathtub outlet pipe is located below the valve body. An annular groove corresponding to the connecting pipe is provided on the end face of the bathtub outlet pipe. A plurality of clamps connected to the annular groove are installed in the annular groove. An inner gear ring corresponding to the outer gear ring is rotatably matched in the annular groove. A plurality of cylinder assemblies are transmission-matched between the inner gear ring and the plurality of clamps.

DETAILED DESCRIPTION

[0022] The utility model will now be further described in detail with reference to the accompanying drawings.

[0023] See also Figure 1-4 As shown, in this embodiment, a bathtub valve that is easy to replace is provided, comprising: a valve body 1 and a bathtub outlet pipe 2, a connecting pipe 5 is installed at the lower side of the valve body 1, an annular groove 7 is opened around the connecting pipe 5, and an outer gear ring 6 is installed around the end of the connecting pipe 5;

[0024] The bathtub outlet pipe 2 is located below the valve body 1. An annular groove 3 corresponding to the connecting pipe 5 is provided on the end face of the bathtub outlet pipe 2. A plurality of clamps connected to the annular clamping groove 7 are installed in the annular groove 3. An inner gear ring 14 corresponding to the outer gear ring 6 is rotatably engaged in the annular groove 13. A plurality of cylinder assemblies are transmission-coordinated between the inner gear ring 14 and the plurality of clamps.

[0025] By means of the multiple clamps arranged in the bathtub outlet pipe 2, when the valve body 1 is inserted into the annular groove 3 through the connecting pipe 5, the multiple clamps automatically clamp the annular groove 7 to fix the valve body 1 on the bathtub outlet pipe 2, thereby facilitating the quick installation of the valve body 1. By means of the multiple cylinder assemblies arranged, the valve body 1 is twisted to drive the multiple clamps to release the clamping of the annular groove 7 through the multiple cylinder assemblies, and then the valve body 1 is removed from the bathtub outlet pipe 2, which facilitates the maintenance or replacement of the valve body 1 after disassembly, thereby improving the efficiency of disassembly of the valve body 1.

[0026] like Figure 2-3 As shown, a plurality of placement grooves 9 are provided on the outer peripheral side of the annular groove 3 of the present embodiment, and the clamping member includes a clamping block 10 which is slidably fitted in the placement groove 9 and is mutually clamped with the annular clamping groove 7, and an elastic telescopic rod 11 installed between the clamping block 10 and the placement groove 9; a plurality of cylinder assemblies are located between the plurality of clamping blocks 10 and the inner gear ring 14, and the cross-sections of the clamping blocks 10 and the annular clamping groove 7 are both mutually fitting triangles.

[0027] When the valve body 1 needs to be installed with the bathtub outlet pipe 2, the valve body 1 is inserted into the bathtub outlet pipe 2 through the connecting pipe 5, and the inclined surfaces of the multiple triangular clamping blocks 10 are squeezed and retracted into the multiple placement grooves 9 by the bathtub outlet pipe 2. When the connecting pipe 5 completely enters the annular groove 3, the outer gear ring 6 is meshed with the inner gear ring 14, and the multiple clamping blocks 10 are clamped with the annular clamping groove 7 through the elastic force of the elastic telescopic rod 11, so that the valve body 1 can be fixedly installed in the bathtub outlet pipe 2.

[0028] like Figure 2-4 As shown, an annular groove 13 is provided on the inner circumference of the annular groove 3 of this embodiment, an inner gear ring 14 is located in the annular groove 13, an inner cavity 16 connected to the annular groove 13 and a plurality of placement grooves 9 is provided in the bathtub outlet pipe 2, and the cylinder assembly includes a cylinder 17 installed in the inner cavity 16, a first connecting rod 18 is provided between the cylinder 17 and the inner gear ring 14, and a second connecting rod 12 is provided between the cylinder 17 and the block 10; a first piston 21 and a second piston 22 are slidably matched in the cylinder 17, a first piston rod 19 fixedly connected to the first connecting rod 18 is provided on one side of the first piston 21, and a second piston rod 20 fixedly connected to the second connecting rod 12 is provided on one side of the second piston 22; the cylinder 17 is a sealed L-shaped structure, and the cylinder 17 is provided with an arc corresponding to the inner gear ring 14.

[0029] When the valve body 1 and the bathtub outlet pipe 2 need to be disassembled, the valve body 1 is twisted, and the valve body 1 drives the outer gear ring 6 to rotate through the connecting pipe 5. The rotation of the outer gear ring 6 drives the inner gear ring 14 to rotate in the annular groove 13. The rotation of the inner gear ring 14 drives the multiple first connecting rods 18 to move. The movement of the multiple first connecting rods 18 drives the multiple first piston rods 19 to move. The multiple first piston rods 19 drive the multiple first pistons 21 to move. The multiple first pistons 21 move in the multiple cylinders 17 and squeeze the multiple second pistons 22 through the atmosphere. The multiple second pistons 22 move through the multiple second piston rods 20 to drive the multiple second connecting rods 12 to move. The multiple second connecting rods 12 move and drive the multiple clamping blocks 10 to move. The multiple clamping blocks 10 move back into the multiple placement grooves 9 to release the clamping connection with the annular clamping groove 7. Then, the valve body 1 is removed from the bathtub outlet pipe 2, which is convenient for maintenance or replacement after the valve body 1 is disassembled, thereby improving the efficiency of disassembling the valve body 1.
