Description

Technical Field

[0001] The utility model relates to the field of faucet water testing equipment, and particularly to a high-performance water testing equipment for a constant temperature faucet. Background Art

[0002] The constant temperature faucet water testing equipment is a device used to detect the water supply performance of a constant temperature faucet. A constant temperature faucet has two connectors, namely a hot water connector and a cold water connector. The hot water connector is connected to the hot water pipeline on the constant temperature faucet water testing equipment, and the cold water connector is connected to the cold water pipeline on the constant temperature faucet water testing equipment. Then, the valve core device on the constant temperature faucet water testing equipment can be connected to the valve core rod on the constant temperature faucet to control the opening and closing of the valve core, thereby controlling the flow rate and temperature of the constant temperature faucet and obtaining effective test data.

[0003] During the actual use of a constant temperature faucet, the rotation of the valve core rod is controlled by a handle to achieve the opening and closing inside the valve core, and finally the outlet water temperature of the constant temperature faucet is effectively adjusted. When the constant temperature faucet water testing equipment detects a constant temperature faucet, a rotating device is used to rotate the valve core rod of the valve core. The rotating device is fixed on a moving frame, and the moving frame can drive the rotating device to move so as to complete the connection with the valve core rod. However, the moving frame of the traditional constant temperature faucet water testing equipment realizes movement and fixation by loosening and tightening screws. Therefore, every time after one constant temperature faucet is detected and a new constant temperature faucet needs to be detected, the screws need to be loosened to make the moving frame drive the rotating device away from the constant temperature faucet, so as to vacate enough space to disassemble the constant temperature faucet from the cold water pipeline and the hot water pipeline. Every time a new constant temperature faucet is detected, the moving frame needs to be moved and fixed each time, resulting in an extremely troublesome replacement process of the constant temperature faucet and seriously affecting the overall water testing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a high-performance water testing equipment for a constant temperature faucet, which can complete the disassembly of the constant temperature faucet without moving the moving frame after completing the connection with the valve core rod of the first constant temperature faucet, and can be connected to the valve core rod of a new constant temperature faucet at the same time, avoiding the situation of wasting a large amount of time due to moving the moving frame and effectively improving the overall water testing efficiency.

[0024] The seat plate 10 and the sliding seat 9 are fixed by a plurality of uniformly distributed fixing screws 40.

[0025] The using method of the utility model is as follows:

[0026] When a water test needs to be carried out on the thermostatic faucet, the hot water connector of the thermostatic faucet can be first connected to the hot water pipeline 5, and the cold water connector of the thermostatic faucet can be connected to the cold water pipeline 6. At this time, the position of the thermostatic faucet is fixed, and the valve core used for control of the thermostatic faucet is arranged at one end of the left and right ends of the thermostatic faucet, or is arranged inside the left and right ends of the thermostatic faucet at the same time, and the valve core rod is exposed outside the thermostatic faucet and faces the connector.

[0027] Immediately afterwards, according to the actual situation, the corresponding moving frame 8 can be moved so that the moving frame 8 moves towards the position where the thermostatic faucet is located. When it is necessary to realize the left and right displacement of the moving frame 8, the first nut 37 can be loosened first. At this time, the first guiding screw 36 can move left and right along the track of the transverse guiding groove 34. After the moving frame 8 drives the connector 17 to move to a position adjacent to the valve core rod, the height can be adjusted so that the connector 17 is lifted or lowered to a position coaxial with the valve core rod, which is convenient for the subsequent connection between the connector 17 and the valve core rod. When it is necessary to adjust the height of the connector 17, since the screw rod 30 is fixed in the movable hole by the clamping force formed between the upper nut 31 and the lower nut 32, only by moving the positions of the upper nut 31 and the lower nut 32 on the screw rod can the height of the lifting plate 26 be changed, thereby effectively changing the height of the motor 12 and the connector 17. When the connector 17 is lifted or lowered to the actual required height, the connector 17 can be fixed by the upper nut 31 and the lower nut 32. Immediately afterwards, the connector can be made to approach the valve core rod through the moving frame 8 until the end of the valve core rod is stuck into the clamping hole of the connector 17. The end of the valve core rod is polygonal, and the inner wall of the clamping hole is also polygonal. Therefore, the clamping hole and the end of the valve core rod can be clamped with each other through the fitting of multiple surfaces, so that when the connector 17 rotates, the valve core rod rotates synchronously.

[0028] After the connection between the connector 17 and the valve core rod is completed, the guide member 33 can be fixed on the slide rail 7 by tightening the first nut 37 to fix the moving frame 8, thereby fixing the positions of the motor 12 and the connector 17. Then, the water test of the thermostatic faucet can be carried out. When it is necessary to control the valve core, only the motor 12 needs to be started. The motor shaft of the motor 12 will drive the control column 14 to rotate through the coupling 13. When the control column 14 rotates, the control column 14 will drive the connector 17 to rotate synchronously through the telescopic rod 16. When the connector 17 rotates, the valve core rod rotates accordingly, realizing the control of the valve core, thereby effectively controlling the flow rate and temperature of the thermostatic faucet and obtaining effective test data.

[0029] After the first thermostatic faucet completes the water test, it can be disassembled. At this time, the hot water joint and the hot water pipeline 5 can be disassembled first, and the cold water joint and the cold water pipeline 6 can be disassembled. After these two places are disassembled, finally, the connector 17 can be disassembled from the valve core rod. At this time, there is no need to move and change the position of the connector 17 through the moving frame 8. Just hold the telescopic rod 16 and make the telescopic rod 16 further retract into the telescopic hole 15. At this time, the spring 20 is compressed and generates elasticity. As the telescopic rod 16 further retracts into the telescopic hole 15, the connector moves away from the valve core rod, and the end of the valve core rod moves out of the connector 17, completing the disassembly between the two. At this time, just pull the thermostatic faucet forward to complete the disassembly of the thermostatic faucet. Immediately afterwards, the new thermostatic faucet can be docked with the cold water pipeline 6 and the hot water pipeline 5. At this time, as the originally held telescopic rod 16 is released, the telescopic rod 16 and the connector 17 will be elastically reset by the spring 20, and the end of the valve core rod of the new thermostatic faucet will accurately enter the card hole of the connector 17. Then, the connection between the cold water joint of the thermostatic faucet and the cold water pipeline 6 and the connection between the hot water joint of the thermostatic faucet and the hot water pipeline 5 are completed through the union nut.

[0030] As can be seen from the above, in the present utility model, only the moving frame 8 needs to be moved when detecting the first thermostatic faucet. When the subsequent new thermostatic faucet needs to be tested for water, just pulling the telescopic rod 16 can realize the rapid disassembly of the thermostatic faucet, reducing a large amount of disassembly and assembly troubles, saving a lot of time, and effectively improving the overall water test efficiency.

[0031] The elastic structure includes long circular holes 19 provided on the outer walls of the upper and lower sides of the control column 14. The long circular holes 19 communicate with the telescopic holes 15. A spring 20 is provided between the end face of the telescopic rod 16 located in the telescopic hole 15 and the bottom of the telescopic hole 15. One end of the telescopic rod 16 located in the telescopic hole 15 is provided with a first screw hole radially penetrating itself. The position of the first screw hole corresponds to the position of the long circular hole 19. The first limit screw 21 passes through the upper and lower long circular holes 19 and is simultaneously screwed into the first screw hole. The screw body of the first limit screw 21 is attached to the inner wall of the long circular hole 19 adjacent to the connector 17. The presence of the first limit screw 21 can not only ensure that the telescopic rod 16 and the control column 14 can rotate synchronously, but also enable the telescopic rod 16 to expand and contract along the track of the telescopic hole 15. At the same time, this connection method facilitates the disassembly and assembly between the telescopic rod 16 and the control column 14.

[0032] One end face center of the telescopic rod 16 adjacent to the middle part of the slide rail 7 is provided with a connection hole 22. One end of the connection head 17 is located in the connection hole 22. One end of the connection head 17 located in the connection hole 22 is provided with a second screw hole radially penetrating itself. Through holes 23 communicating with the second screw hole are provided on the outer walls of the upper and lower sides of the telescopic rod 16 adjacent to the middle part of the slide rail 7. The second limit screw 24 passes through the upper and lower through holes 23 and is simultaneously screwed into the second screw hole. The second limit screw 24 can effectively realize the connection and fixation between the connection head 17 and the telescopic rod 16, and this connection method facilitates the disassembly and assembly between the connection head 17 and the telescopic rod 16.

[0033] The seat plate 10 and the sliding seat 9 are fixed by a number of uniformly distributed fixing screws 40. This fixing method not only facilitates the disassembly and assembly between the seat plate 10 and the sliding seat 9, but also facilitates the change of the position of the seat plate 10.

[0034] One outer wall of the sliding seat 9 is provided with a fastening screw hole communicating with its internal space. A fastening screw 41 matching with it is screwed in the fastening screw hole. The end of the screw body of the fastening screw 41 presses tightly on one of the outer walls on the left and right sides of the moving frame 8. The fixation of the sliding seat 9 is realized by the fastening force of the fastening screw 41. This fixing method not only facilitates the front and back movement of the sliding seat 9 along the track of the moving frame 8, but also facilitates the disassembly and assembly of the sliding seat 9.
