If the lifting valve is not in the rising state, then manually rotate the rotating shaft to raise the baffle towards the support until the top of the baffle is close to the bottom of the support, and then connect the water pipe to the threaded hole on the outer wall of the connecting block. If it is necessary to remove the connecting block connected to the fixing block, simply manually rotate the rotating shaft on the corresponding lifting valve to lower it to the bottom of the fixing block to lock the water, and then manually unscrew the connecting block. It has the following technical problems:
[0004] The above structure has external threads on the outside of the rotating shaft. The exposed external threads are prone to dust accumulation, making it more difficult for the rotating shaft to rotate. Utility Model Content
[0005] To address the problem mentioned in the background section that the exposed rotating shaft in the prior art is prone to dust accumulation, this utility model provides the following technical solution:
[0006] A splicing four-way pipe fitting, comprising a four-way pipe fitting body;
[0007] The four-way pipe fitting body has multiple through holes in the middle, and the inside of the four-way pipe fitting body is equipped with opening and closing components for opening and closing the multiple through holes.
[0008] The opening and closing component includes a sealing block, a connecting block two is installed at the upper end of the sealing block, and a screw is installed at the middle of the upper end of the connecting block two.
[0009] The upper end of the four-way pipe fitting body is equipped with a top cover, and the upper end of the top cover is equipped with a rotating pipe for cooperating with the screw to control the sealing block to move up and down.
[0010] Furthermore, the four-way pipe fitting body has a sealing groove in the middle for inserting a sealing block, and the sealing groove is connected to multiple through holes. The sealing groove has an isosceles trapezoidal cross section, and the upper end of the sealing groove has an installation groove, and the two sides of the installation groove have sliding grooves.
[0011] Furthermore, the top cover is fitted with a bolt for fixing the top cover to the upper end of the four-way pipe body, and a bearing inner ring and a bearing outer ring are installed in the middle of the top cover. The bearing inner ring has multiple threaded holes in the middle, and the top cover has a threaded hole in the middle.
[0012] Furthermore, the middle part of the rotating tube is provided with an internal thread for cooperating with the screw to control the up and down movement of the sealing block, and the upper end of the rotating tube is equipped with a knob for controlling the rotation of the rotating tube.
[0013] Furthermore, the lower end of the rotating tube is provided with multiple limiting grooves, and an internal hexagon bolt is installed inside the limiting groove to limit the position of a pair of rotating tubes that are matched with the threaded hole.

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0026] Please see Figures 1-4 This utility model provides a splicing four-way pipe fitting, including a four-way pipe fitting body 100. The four-way pipe fitting body 100 has multiple through holes 104 for water supply in the middle. The four-way pipe fitting body 100 is equipped with an opening and closing component 200 for opening and closing the multiple through holes 104. The opening and closing component 200 includes a sealing block 210. The four-way pipe fitting body 100 has a sealing groove 103 in the middle for the sealing block 210 to be inserted. The sealing groove 103 is connected to the multiple through holes 104. The cross section of the sealing groove 103 is an isosceles trapezoid so that when the sealing block 210 moves downward, the sealing gasket 211 simultaneously seals the multiple through holes 104.
[0027] The upper end of the sealing groove 103 is provided with an installation groove 101, and the two sides of the installation groove 101 are provided with sliding grooves 102. The upper end of the four-way pipe fitting body 100 is provided with a top cover 110, and the edge of the top cover 110 is provided with multiple bolts 111 for fixing the top cover 110 to the upper end of the four-way pipe fitting body 100. At the same time, the top of the four-way pipe fitting body 100 is provided with threaded holes that are screwed to the bolts 111.
[0028] The top cover 110 has an inner bearing ring 112 and an outer bearing ring 113 installed in its center. A circular hole is formed in the center of the top cover 110, and the outer wall of the outer bearing ring 113 is fixedly installed within this hole. The water level of the inner bearing ring 112 is higher than the horizontal level of the outer bearing ring 113 to facilitate smoother rotation of the rotating pipe 120. Multiple threaded holes 114 are formed in the center of the inner bearing ring 112, and a second threaded hole 115 is formed in the center of the top cover 110.
[0029] The sealing block 210 has an isosceles trapezoidal cross section. A connecting block 212 is fixedly installed at the upper end of the sealing block 210. A screw 214 is fixedly installed at the middle of the upper end of the connecting block 212. A sealing gasket 211 is fixedly pasted on the outside of the sealing block 210. A slider 213 that slides in the sliding groove 102 is fixedly installed on the side of the connecting block 212. The sealing block 210 moves up and down in the sealing groove 103 and the mounting groove 101, so that the sealing block 210 releases the closure of multiple through holes 104 or simultaneously closes multiple through holes 104. When the connecting block 212 slides in the mounting groove 101, the slider 213 slides in the sliding groove 102.
[0030] The top cover 110 is equipped with a rotating tube 120 for cooperating with the screw 214 to control the sealing block 210 to move up and down. The middle of the rotating tube 120 is provided with an internal thread 121 for cooperating with the screw 214 to control the sealing block 210 to move up and down. When the rotating tube 120 rotates, the screw 214 can move up or down under the guidance of the internal thread 121, so as to drive the sealing block 210 to move up and down synchronously. By setting the rotating tube 120, this utility model avoids dust from contaminating the screw 214 or the internal thread 121, thereby avoiding the blockage of the transmission between the internal thread 121 and the screw 214.
[0031] A knob 122 for controlling the rotation of the rotating tube 120 is fixedly installed at the upper end. Multiple limiting grooves 123 are provided at the lower end of the rotating tube 120. Hexagon socket head cap screws 124 are installed inside the limiting grooves 123 to limit the rotation of the rotating tube 120 in conjunction with threaded holes 114. The hexagon socket head cap screws 124 and threaded holes 114 are screwed into each other, thus fixing the rotating tube 120 to the upper end of the bearing inner ring 112. A retaining ring 125 for dust prevention is fixedly installed on the lower outer wall of the rotating tube 120. The bottom horizontal height of the retaining ring 125 is lower than the bottom horizontal height of the rotating tube 120, and also lower than the upper horizontal height of the bearing outer ring 113. The outer diameter of the rotating tube 120 is larger than the outer diameter of the bearing outer ring 113, and the inner diameter of the bearing inner ring 112 is larger than the inner diameter of the internal thread 121.
[0032] A connecting block 126 is fixedly installed on one side of the retaining ring 125. A bolt 127 is installed in the middle of the connecting block 126 to limit the rotation pipe 120 in conjunction with the threaded hole 115. The bolt 127 and the threaded hole 115 are screwed together. When the sealing block 210 blocks multiple through holes 104, the bolt 127 can be screwed into the threaded hole 115, so that the rotation pipe 120 cannot rotate, thereby ensuring that the sealing block 210 always blocks the through holes 104 and prevents water leakage.
[0033] When multiple through holes 104 need to be opened for water supply, after unscrewing bolt 127 from threaded hole 115, knob 122 can be rotated. The internal thread 121, in conjunction with screw 214, drives the sealing block 210 from sealing groove 103 to mounting groove 101, simultaneously exposing multiple through holes 104 for water supply. When multiple through holes 104 need to be closed, knob 122 is rotated in the opposite direction. Under the guidance of internal thread 121, screw 214 drives sealing block 210 downward, so that sealing gasket 211 seals multiple through holes 104.
[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
