[0028] The connecting bridge 2 includes a central column 201 located between the plugging covers 1, a plug-in is provided between the plugging covers 1 and the central column 201, a slot matching the plug-in is provided on the central column 201, and the plug-in is snapped onto the slot; through the cooperation of the plug-in and the slot, the plugging cover 1 can be fixed on the central column 201, which is convenient for disassembly and assembly, so that the number of plugging covers 1 installed on the central column 201 can be adjusted according to the number of water pipes.

[0029] The slot is strip-shaped, and the plug-in is divided into a fixing strip 202 arranged on the blocking cover 1 and a plug-in rod 203 arranged at both ends of the fixing strip 202. The plug-in rod 203 is inserted into the slot, and a clamping block 205 is provided at the end of the plug-in rod 203. The clamping block 205 is provided with an embedding groove 206 that matches the edge of the slot 204; the clamping block 205 is wedge-shaped, which is convenient for inserting into the slot 204, and is engaged with the two ends of the slot 204 through the embedding groove 206, so that the plug-in rod 203 is fixed on the slot 204. At the same time, because there are two plug-in rods 203 connected to the two ends of the slot 204, the elasticity of the plug-in rod 203 can be used to clamp the two plug-in rods 203 in the slot 204, and when it needs to be pulled out, it only needs to squeeze the two clamping strips 31 to remove the plug-in block from the slot 204, which is convenient for disassembly and assembly.

[0031] A sealing ring 7 is provided inside the plugging cover 1, and a stepped groove is provided on the inner side of the sealing ring 7. The sealing ring 7 covers the port of the water pipe, and a rubber block 8 is provided on the sealing ring 7. An extrusion rod 9 is provided inside the plugging cover 1, and the end of the extrusion rod 9 is in close contact with the rubber block 8. When the plugging cover 1 is put on the water pipe, the water pipe port is stuck in the stepped groove. At this time, the sealing ring 7 can be squeezed by squeezing the rubber block 8 to squeeze the sealing ring 7, so that the sealing ring 7 expands, thereby locking the water pipe while achieving a better sealing effect to avoid leakage.

[0032] The plugging cover 1 is provided with a sleeve frame 10, and the extrusion rod 9 is located in the sleeve frame 10. The end of the extrusion rod 9 away from the plugging cover 1 is located in the connecting bridge 2. A push button 11 connected to the button 4 is provided in the connecting bridge 2. A knob 12 is provided at the bottom of the push button 11. A push groove 13 is provided on the knob 12. The end surface of the extrusion rod 9 located in the connecting bridge 2 is embedded in the push groove 13, and the end surface of the extrusion rod 9 located in the push groove 13 is a wedge-shaped surface; the extrusion rod 9 is restricted by the sleeve frame 10 to prevent the extrusion rod 9 from being disengaged, and the extrusion rod 9 can also be restricted. In the moving direction, the push groove 13 is annular to avoid the situation that the extrusion rod 9 and the push groove 13 are stuck to each other due to the rotation of the knob 12. Since the end of the extrusion rod 9 is located in the push groove 13, when the push knob 12 is pushed down, the extrusion rod 9 is squeezed out by the push groove 13, and the extrusion rod 9 is pushed to move in the reverse direction. The end of the extrusion rod 9 close to the blocking cover 1 will start to squeeze the rubber block 8, thereby squeezing the sealing ring 7, so that the rubber sealing ring 7 also starts to expand, which can not only improve the fixed friction, but also improve the reliability of the seal.

[0033] A strip 14 is provided inside the plug cover 1, a top groove 15 matching with the strip 14 is provided on the push button 11, a bottom groove 16 matching with the strip 14 is provided on the knob 12, a wedge-shaped block 18 is provided at the bottom end of the push button 11, and a short groove 17 matching with the bottom end of the strip 14 is provided on the knob 12. The bottom end of the strip 14 is a wedge-shaped surface, and the end faces of the push button 11 and the end faces of the knob 12 are both wedge-shaped surfaces.

[0034] When the plugging cover 1 and the water pipe need to be fixed, the bottom end of the strip 14 is located in the bottom groove 16. Since the depth of the bottom groove 16 is greater than the depth of the short groove 17, the knob 12 is located at a higher position and the push groove 13 is located at a high point. At this time, the end of the extrusion rod 9 is embedded in the push groove 13. By pressing the button 4, the button 4 pushes the push button 11 down. When the strip 14 rises along the top groove 15, since the strip 14 is fixed on the central column 201, the strip 14 will not rotate and move. When the strip 14 is completely separated from the bottom groove 16, since the bottom end of the strip 14 is a wedge-shaped surface and the end face of the knob 12 is also a wedge-shaped surface, when the strip 14 and the knob 12 are separated, After separation, the end face of the wedge block 18 and the wedge face at the bottom end of the strip block 14 are located in the same plane, which makes the end face of the knob 12 rise along the end face formed by the wedge block 18 and the strip block 14, so that the bottom end of the strip block 14 can be embedded in the short groove 17, and the strip block 14 is used to support the knob 12, so that the knob 12 can no longer rise. At this time, since the depth of the bottom groove 16 is greater than the depth of the short groove 17, the push button 11 is lowered a certain distance compared to the initial position, so that the push groove 13 is lowered a certain distance relative to the initial position, and the end of the extrusion rod 9 will be separated from the push groove 13, and the extrusion rod 9 is pushed to squeeze the rubber block 8, thereby achieving the purpose of fixing the plug cover 1 and the water pipe.

[0035] When it is necessary to reset, the bottom end of the bar 14 is located in the short groove 17, the button 4 is pressed to push the push button 11 down, the bar 14 rises relative to the push button 11 and the knob 12, the bar 14 is embedded in the top groove 15, the bar 14 is separated from the short groove 17, the bottom end of the bar 14 and the bottom end of the wedge block 18 form a wedge surface, the knob 12 rises, and the end surface of the knob 12 can rotate and rise along the bottom end of the bar 14 and the bottom end of the wedge block 18, the bottom end of the bar 14 moves to the bottom groove 16, and is resisted by the bottom groove 16. The knob 12 can be raised, and the bottom end of the bar 14 will abut against the bottom of the bottom groove 16. Since the depth of the short groove 17 is less than the depth of the bottom groove 16, the position of the knob 12 is higher than that of the initial state, thereby achieving the purpose of the knob 12 rising. When the knob 12 rises, the push groove 13 is driven to rise together, so that the extrusion rod 9 can be pushed into the push groove 13 when the expansion force of the compressed rubber block 8 decreases, completing the resetting of the extrusion rod 9, so that the plugging cover 1 is no longer stuck on the water pipe, and it is convenient to pull it out.

[0036] The button 4 is in a hat shape, and a push ring 19 is provided at one end of the push button 11 connected to the button 4. An ejection spring 20 is provided between the push ring 19 and the inner wall of the plugging cover 1, and a return spring 21 is provided between the knob 12 and the plugging cover 1. The return spring 21 is sleeved on the outside of the knob 12; the push button 11 and the knob 12 are reset by the ejection spring 20 and the return spring 21.

[0037] A middle column 22 is provided in the middle of the knob 12, and a middle hole is provided in the push button 11, which is inserted into the middle column 22. The wedge-shaped surfaces at the ends of the push button 11 and the knob 12 are wavy, and the wedge-shaped surface at the end of the wedge block 18, the wedge-shaped surface at the end of the strip 14, the wedge-shaped surface in the short groove 17, the wedge-shaped surface at the end of the push button 11 and the wedge-shaped surface at the end of the knob 12 have the same inclination angle; the middle hole and the middle column 22 can prevent the push button 11 and the knob 12 from being misaligned.

[0038] The technical effect of the present invention is: multiple plugging covers 1 are connected together through a connecting bridge 2, multiple plugging covers 1 can be blocked at the same time, and the fixing and loosening of multiple plugging covers 1 can be controlled at one time through a button 4, the operation is convenient, and different numbers of water pipes can be adapted by increasing or decreasing the number of plugging covers 1.
