Description

Technical Field

[0001] This invention belongs to the field of faucet testing technology, and particularly relates to a multi-station synchronous testing device for bathroom faucets. Background Technology

[0002] Bathroom faucets are water taps installed in toilets or bathrooms. After the bathroom faucets are manufactured, in order to ensure that the faucets on the market are free of cracks and that the water pressure resistance of the internal filter meets the standards, it is necessary to use testing devices to test the sealing effect of the bathroom faucet and the pressure resistance of its internal filter. Traditional bathroom faucet pressure resistance and sealing ability testing devices usually use clamping components to fix the bathroom faucet in place to ensure stable connection between the faucet and the water outlet pipe. Then, the operator manually turns on the faucet to test the water pressure resistance and sealing. The operation steps are relatively cumbersome and reduce the testing efficiency.

[0003] Based on this problem, patent document CN118549115B discloses a device for testing the pressure resistance and sealing ability of bathroom faucets. This technology uses a positioning slide column to move inward along a positioning groove, so that the arc surface of the clamping part on the positioning slide column comes into contact with the outer wall of the faucet under test, thereby clamping and positioning the faucet under test. Furthermore, through the setting of a switch push rod, the testing device can automatically turn on the switch of the faucet under test after the positioning slide column positions the faucet under test, so that the faucet under test can start dispensing water. The device tests the water pressure resistance of the embedded filter screen inside the faucet under test, and at the same time, it determines whether there is water leakage at the non-outlet position of the faucet by observing the non-outlet position of the faucet, thus testing the sealing effect of the faucet.

[0004] However, in practice, it was found that although the detection device of the above technology can turn on the faucet switch at the same time during the clamping and positioning process, it can only detect one faucet at a time. The upper limit of detection efficiency improvement is low, which is difficult to meet the high-efficiency detection requirements in large-scale production scenarios. Therefore, there is still room for improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a multi-station synchronous detection device for bathroom faucets, thereby solving the problem that existing detection devices can only detect one faucet at a time and have insufficient detection efficiency.

[0006] In view of this, the present invention provides a multi-station synchronous detection device for bathroom faucets, comprising: The testing chamber contains a testing solution. The workbench is set on the testing box. Multiple testing stations are set at intervals on the workbench. Each testing station includes a swing clamp, a switch pusher, and a liquid injection device. The swing clamp can clamp or release the faucet by swinging. The switch pusher can open or close the faucet's switch handle. The liquid injection device can inject the testing liquid in the testing box into the faucet's inlet at a preset pressure. Synchronous drive rod, which is slidably set on the worktable along the distribution direction of multiple detection stations, can connect multiple swing clamping parts and can drive multiple swing clamping parts to swing simultaneously through linear motion to clamp or release the faucet; The drive locking component can drive the synchronous drive rod to perform linear reciprocating motion and can lock the synchronous drive rod when the drive stops.

[0007] In the above technical solution, the swing clamping component further includes: Fixed clamp is set on the workbench and has a positioning groove that matches the outer contour of the faucet. The swing clamp is rotatably mounted on the worktable. The swing clamp is located on the side of the fixed clamp near the positioning groove. The side wall of the swing clamp near the positioning groove is provided with a matching groove that matches the outer contour of the faucet. A transmission block is mounted on a swing clamp, and a compensation block is slidably mounted on the transmission block. The sliding direction of the compensation block is inclined to the movement direction of the synchronous drive rod. In each set of swing clamping components, the compensation block is rotatably connected to the synchronous drive rod.

[0008] In the above technical solution, the switch actuator further includes: A support frame is installed above the workbench. A sliding rail is provided on the support frame, and a sliding seat is slidably mounted on the sliding rail along a first direction. Two parallel push rods are mounted on a sliding seat, and a space is formed between the two push rods for the switch handle to enter. The pusher component drives the slide seat to reciprocate in a first direction.

[0009] In the above technical solution, the driving component further includes: The transmission rod is mounted on the sliding seat. The force-applying rod is mounted on the swing clamp. The force-applying rod can move in an arc under the drive of the swing clamp. The end of the force-applying rod away from the swing clamp is connected to the transmission rod. As the swing clamp approaches the faucet, the force rod and the transmission rod work together to drive the sliding seat to move away from the faucet. As the swing clamp moves away from the faucet, the force rod and the transmission rod work together to drive the sliding seat to move closer to the faucet.

[0010] In the above technical solution, a first elastic element is further provided between the sliding seat and the sliding track. In its natural state, the two push rods close the switch handle. During the process of the two push rods opening the switch handle, the first elastic element is compressed, and the force-applying rod can separate from the transmission rod.

[0011] In the above technical solution, a displacement groove is further provided at one end of the transmission rod near the force-applying rod, and one end of the force-applying rod is connected to the displacement groove. The force-applying rod can move in the displacement groove in a direction perpendicular to the movement of the transmission rod, and the force-applying rod can rotate in the displacement groove along its own axis.

[0012] Furthermore, the above technical solution also includes: A locking seat is provided on one side of the sliding seat. The locking seat is slidably mounted on the bracket in a direction perpendicular to the movement of the sliding seat, and a locking groove is provided on the locking seat. A connecting seat is provided on a sliding seat, and the connecting seat has a connecting groove. The snap-fit ​​block has one end that is slidably disposed in the connecting groove in a direction perpendicular to the movement of the sliding seat. The side wall of the snap-fit ​​block near the locking seat is inclined, so that the snap-fit ​​block can contact the locking seat as the sliding seat moves away from the faucet. The second elastic element is disposed in the connecting groove, and its two ends are respectively connected to the snap-fit ​​block and the bottom surface of the connecting groove. When the locking block is pressed by the locking seat, it will partially retract into the connecting groove and continue to move along the surface of the locking seat toward the locking groove. During this process, the second elastic element is compressed. When the locking block comes into contact with the locking groove, it can be locked into the locking groove under the push of the second elastic element. After the locking seat moves toward the bracket, the locking block can be removed from the locking groove.

[0013] In the above technical solution, the bracket is further provided with a de-energized electromagnet and a third elastic element. One end of the third elastic element is connected to the locking seat. The locking seat is provided with a metal block that cooperates with the de-energized electromagnet. When the de-energized electromagnet is de-energized, it can attract the metal block. At this time, the third elastic element is stretched, and the locking block can be locked into the locking groove. When the de-energized electromagnet is energized, it loses its attraction. At this time, the locking seat is pulled closer to the bracket by the pull of the third elastic element, and the locking block is withdrawn from the locking groove.

[0014] In the above technical solution, the liquid injection component further includes: The mounting slot extends through the upper and lower surfaces of the worktable and is located between the fixed clamp and the swing clamp. The injection tube is located below the workbench. One end of the injection tube passes through the mounting groove and can be connected to the inlet of the faucet. The other end of the injection tube is inserted into the test liquid. The injection pump, installed on the injection pipe, is used to provide the injection pressure required for testing.

[0015] In the above technical solution, the driving locking component further includes a locking cylinder, which is mounted on the worktable, and the piston of the locking cylinder is connected to one end of the synchronous drive rod.

[0016] The beneficial effects of this invention are: 1. By setting up multiple sets of identical testing stations and cooperating with synchronous drive rods, the synchronous clamping, switching control and liquid injection testing of multiple faucets can be achieved, which solves the limitation of existing single-station equipment that can only test one faucet at a time. The testing efficiency can be increased exponentially according to the number of stations (e.g., 4 sets of stations increase efficiency by 4 times). There is no need to operate each station individually, which can efficiently match the testing needs of industrialized mass production and significantly reduce the unit product testing time cost.

[0017] 2. The device achieves full automation of the entire process—"synchronous clamping - automatic valve opening - liquid injection detection - automatic valve closing - synchronous release"—through a mechanically linked structure, eliminating the need for manual fixing, opening / closing, or unlocking of each faucet. Furthermore, the use of identical drive parameters, clamping force, and liquid injection pressure settings across multiple stations avoids inconsistencies in testing conditions caused by manual operation, ensuring a uniform testing environment for all tested faucets and significantly improving the accuracy and reliability of the test results.

[0018] 3. The positioning groove and mating groove of the swing clamping component adopt an arc design that matches the outer contour of the faucet. Combined with the elastic cushioning of the rubber anti-slip pad, it can be adapted to cylindrical bathroom faucets of different diameters. It can meet the testing requirements of various product models without changing the clamping components. The injection pump is a variable frequency booster pump, which can flexibly adjust the injection pressure according to the pressure resistance testing standards of different faucets, further expanding the applicability of the equipment and reducing the equipment investment cost for testing multiple product models.

[0019] 4. The switch actuator is equipped with a double locking structure consisting of a snap-fit ​​block, a locking seat, and a power-off type electromagnet. During testing, it can firmly lock the sliding seat, keeping the switch handle in the open position and preventing accidental closure due to water pressure impact or equipment vibration, thus ensuring the continuity of liquid injection testing. The power-off type electromagnet is designed with a power failure protection function, ensuring that the locking state does not fail in the event of a sudden power failure, preventing equipment damage or invalidation of test data. At the same time, the materials selected for each component take into account both strength and protection (such as stainless steel for corrosion resistance and rubber pads for damage prevention), extending the service life of the equipment while preventing damage to the faucet surface during testing.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] like Figure 1 As shown, the faucet C to be tested in this invention has an inlet C1, a liquid channel, an outlet C2, and a switch handle C3. The liquid channel is located in the faucet C, with the inlet C1 and outlet C2 being the two ports of the liquid channel. The switch handle C3 can control the connection or blockage of the liquid channel. Swinging the switch handle C3 outward opens the liquid channel, while swinging it inward closes the liquid channel. A filter screen is installed at the end of the liquid channel near the outlet C2. This invention provides a multi-station synchronous detection device for bathroom faucets, including a detection box 1, a workbench 2, multiple detection stations J, a synchronous drive rod 3, and a drive locking component 4; I. Structure and Connection Relationship of Core Components (a) Testing box 1 Please see Figures 2-6 The testing chamber 1 is a rectangular box structure with an open top, which can hold the testing liquid (preferably clean water, which is low in cost and easy to observe for leakage). The testing chamber 1 is made of 304 stainless steel, which has good corrosion resistance and structural strength, and can prevent the chamber from rusting due to long-term contact with the testing liquid, thus extending the service life of the equipment.

[0037] Please see Figure 2 and Figure 4 The bottom of the test chamber 1 is equipped with a drain pipe 101, and a shut-off valve is installed on the drain pipe 101 to facilitate the discharge of the test liquid in the chamber for equipment cleaning or replacement of the test liquid after the test is completed.

[0038] Please see Figure 3 The top of the inner wall of the test box 1 is provided with an annular positioning protrusion 102. The top surface of the positioning protrusion 102 is slightly lower than the top surface of the test box 1. The positioning protrusion 102 is used to support the workbench 2 to ensure the levelness and stability of the workbench 2 after installation.

[0039] (ii) Workbench 2 Please see Figure 3 The workbench 2 is a rectangular plate structure, horizontally mounted on the positioning protrusion 102 of the inspection box 1, and fixedly connected to the positioning protrusion 102 by bolts to ensure that the workbench 2 does not shift during the inspection process. The workbench 2 is made of high-strength aluminum alloy, which combines lightweight and high strength, reducing the overall weight of the equipment and providing a stable mounting foundation for each inspection station. Its surface is anodized to improve wear resistance and corrosion resistance.

[0040] Please see Figure 2 Multiple testing stations J are spaced along the length of the workbench 2. Each testing station J has the same structure, and the spacing is designed according to the size of a standard bathroom faucet C to ensure that the stations do not interfere with each other, while maximizing the use of the space on the workbench 2.

[0041] (III) Inspection Station J Please see Figure 4 Each testing station J includes a swing clamp 5, a switch pusher 6, and a liquid injection component 7. The three work together to complete the positioning, switch control, and liquid injection testing of the faucet C.

[0042] 1. Swinging clamp 5 The swing clamp 5 is used to clamp and fix the faucet C to be tested, and includes a fixed clamp 501, a swing clamp 502, a transmission block 503 and a compensation block 504.

[0043] Please see Figure 3 and Figure 4 The fixed clamp 501 is bolted to the workbench 2. The side wall of the fixed clamp 501 near the faucet C has a positioning groove 5011 that matches the outer contour of the faucet C. The inner wall of the positioning groove 5011 is lined with a rubber anti-slip pad. The rubber material has good elasticity and friction, which can prevent damage to the surface of the faucet C during clamping and improve clamping stability. The fixed clamp 501 is made of ductile iron, which has high strength, high toughness, and good wear resistance, and can withstand the mechanical load from long-term clamping operations.

[0044] Please see Figure 3 and Figure 4The swing clamp 502 is rotatably mounted on the worktable 2 via a rotating shaft 5022. A bearing is installed between the rotating shaft 5022 and the worktable 2 to reduce rotational friction and ensure smooth movement of the swing clamp 502. The swing clamp 502 is located on the side of the fixed clamp 501 near the positioning groove 5011. A mating groove 5021, which matches the outer contour of the faucet C, is provided on the side wall of the swing clamp 502 near the positioning groove 5011. A rubber anti-slip pad is also attached to the inner wall of the mating groove 5021, which, together with the positioning groove 5011, forms a ring-shaped clamping grip on the faucet C. The material of the swing clamp 502 is the same as that of the fixed clamp 501, both being ductile iron, ensuring structural strength matching.

[0045] Please see Figure 3 and Figure 4 The transmission block 503 is welded to the bottom of the swing clamp 502. An inclined groove is formed on the transmission block 503, and a compensation block 504 is slidably disposed within the groove. The sliding direction of the compensation block 504 is inclined to the movement direction of the synchronous drive rod 3 (preferably at an angle of 45°). The compensation block 504 is made of polytetrafluoroethylene (PTFE), which has excellent self-lubricating and wear-resistant properties, reducing frictional losses between itself and the transmission block 503 and the synchronous drive rod 3, thus ensuring transmission efficiency. The compensation block 504 in each set of swing clamping components 5 is rotatably connected to the synchronous drive rod 3 via a pin, realizing power transmission between the synchronous drive rod 3 and the swing clamp 502.

[0046] 2. Switch actuator 6 The switch pusher 6 is used to automatically control the opening and closing of the faucet C switch handle C3, and includes a bracket 601, a sliding seat 603, a push rod 604 and a pusher.

[0047] Please see Figure 3 and Figure 7 The bracket 601 is fixedly installed on the workbench 2 by bolts. It has a door-shaped structure and provides installation support for other parts of the switch pusher 6. The bracket 601 is made of stainless steel to ensure structural stability and corrosion resistance. The bracket 601 is equipped with a horizontal sliding rail 602. The sliding rail 602 can adopt a dovetail groove structure and cooperate with the sliding seat 603 to achieve precise guidance. The sliding seat 603 is slidably mounted on the sliding track 602 and can reciprocate along the first direction X (i.e., the direction parallel to the rotation plane of the faucet C switch handle C3). In this embodiment, the first direction X is also the distribution direction of multiple detection stations J. The sliding seat 603 is made of aluminum alloy, which is lightweight and flexible in movement.

[0048] Please see Figure 7 and Figure 8There are two push rods 604, which are distributed in parallel and are fixed to the sliding seat 603 by bolts. The space between the two push rods 604 is formed for the switch handle C3 to enter. The push rods 604 are made of hard plastic, which has a certain rigidity and is lightweight, and can prevent scratching the surface of the handle when pushing the switch handle C3.

[0049] The pusher is used to drive the sliding seat 603 to move. In this embodiment, the pusher includes a transmission rod 8 and a force-applying rod 9. (See also...) Figure 7 and Figure 8 The transmission rod 8 is fixed to the sliding seat 603 by bolts, and the force-applying rod 9 is fixed to the swing clamp 502 by welding. The force-applying rod 9 can make arc motion under the drive of the swing clamp 502. Specifically, there are two ways to connect the transmission rod 8 and the force-applying rod 9. For the first connection method, please refer to [link / reference needed]. Figure 7 and Figure 8 A first elastic element 10 is provided between the sliding seat 603 and the sliding rail 602. The first elastic element 10 is preferably a compression spring, sleeved on the end of the sliding rail 602, with its two ends abutting against the sliding seat 603 and the bracket 601, respectively. In its natural state, the first elastic element 10 causes the two push rods 604 to close the switch handle C3. During the process of the two push rods 604 opening the switch handle C3, the first elastic element 10 is compressed, and the force rod 9 can separate from the transmission rod 8. Thus, during the process of the swing clamp 502 clamping the faucet C, the force rod 9 is driven to move. The end of the force rod 9 contacts the transmission rod 8 and pushes the sliding seat 603 away from the faucet C through the transmission rod 8, causing the two push rods 604 to open the switch handle C3. During this process, the first elastic element 10 is compressed. During the process of the swing clamp 502 releasing the faucet C, the force rod 9 is driven away from the transmission rod 8. At this time, the elastic force of the first elastic element 10 drives the sliding seat 603 to return to its original position, causing the two push rods 604 to close the switch handle C3. The first elastic element 10 can be made of spring steel to ensure stable elastic performance; For the second connection method, please refer to [link / reference]. Figure 12 The transmission rod 8 has a displacement groove 11 at one end near the force-applying rod 9. The force-applying rod 9 is cylindrical, and its end away from the swing clamp 502 is inserted into the displacement groove 11, forming a movable connection with the transmission rod 8. The force-applying rod 9 can move in the displacement groove 11 in a direction perpendicular to the movement of the transmission rod 8, and can also rotate along its own axis, ensuring that the arc motion of the swing clamp 502 can be smoothly converted into the linear motion of the transmission rod 8. Both the transmission rod 8 and the force-applying rod 9 can be made of 45# steel, which has good strength and toughness and can withstand the mechanical load during the transmission process.

[0050] In a preferred embodiment, the switch pusher 6 further includes a locking mechanism for locking the position of the sliding seat 603 to ensure that the switch handle C3 remains in the open state during the detection process; the locking mechanism includes a locking seat 12, a connecting seat 13, a snap-fit ​​block 14, and a second elastic member 15.

[0051] For details, please refer to Figure 10 The locking seat 12 is slidably mounted on the bracket 601 in a direction perpendicular to the movement of the sliding seat 603. For example, a guide rod is provided at the bottom of the locking seat 12, and a guide hole is provided on the bracket 601 to slide relative to the bracket 601 through the cooperation of the guide rod and the guide hole. The locking seat 12 is provided with a locking groove 1201, and the material of the locking seat 12 can be stainless steel. Please see Figure 10 The connecting seat 13 is fixed to the sliding seat 603 by bolts. The connecting seat 13 has a connecting groove 1301 that penetrates two opposite surfaces of the connecting seat 13 to form two openings. One of the openings is removably sealed by a pressure cover 1302. The pressure cover 1302 forms the bottom surface of the connecting groove 1301 and is fixed to the connecting seat 13 by bolts. Please see Figure 10 One end of the snap-fit ​​block 14 extends into the other opening of the connecting groove 1301 and slides in the connecting groove 1301 in a direction perpendicular to the movement of the sliding seat 603. The side wall of the snap-fit ​​block 14 near the locking seat 12 is inclined, which facilitates being squeezed and pushed when in contact with the locking seat 12. The snap-fit ​​block 14 can be made of hard alloy to improve wear resistance and structural strength. Please see Figure 10 The second elastic element 15 is disposed in the connecting groove 1301, preferably a compression spring, with its two ends connected to the snap-fit ​​block 14 and the bottom surface of the connecting groove 1301 respectively; the second elastic element 15 can be made of spring steel, which has good elastic recovery performance and fatigue strength. In addition, please see Figure 10 The bracket 601 is also equipped with a de-energized electromagnet 16 and a third elastic element 17. The de-energized electromagnet 16 is fixed to the bracket 601 by bolts. The third elastic element 17 is preferably a tension spring, one end of which is connected to the locking seat 12 and the other end is fixed to the bracket 601. The locking seat 12 is equipped with a metal block 18 (made of ferromagnetic material) that cooperates with the de-energized electromagnet 16. When the de-energized electromagnet 16 is de-energized, it has magnetic attraction and can attract the metal block 18. At this time, the third elastic element 17 is stretched, and the locking block 14 can be locked into the locking groove 1201. When the de-energized electromagnet 16 is energized, it loses its attraction. Under the tension of the third elastic element 17, the locking seat 12 moves closer to the bracket 601, causing the locking block 14 to exit from the locking groove 1201.

[0052] 3. Liquid injection component 7 The liquid injection component 7 is used to inject the test liquid in the test box 1 into the inlet C1 of the faucet C at a preset pressure. In this embodiment, the liquid injection component 7 includes a mounting groove 701, a liquid injection pipe 702 and a liquid injection pump 703. Please see Figure 3 and Figure 7 The mounting groove 701 runs through the upper and lower surfaces of the workbench 2 and is located between the fixed clamp 501 and the swing clamp 502, providing clearance space for the connection between the injection pipe 702 and the faucet C. Please see Figure 3 and Figure 5 The injection tube 702 is located below the workbench 2. One end of it passes through the mounting groove 701 and connects to the inlet C1 of the faucet C. A rubber sealing sleeve is provided at the connection point to ensure a tight seal and prevent leakage during injection. The other end of the injection tube 702 is inserted into the test liquid in the test chamber 1. The injection tube 702 is made of food-grade silicone tubing, which has good flexibility and corrosion resistance and will not contaminate the test liquid. Please see Figure 3 and Figure 5 The injection pump 703 is installed on the injection pipe 702 to provide the injection pressure required for testing. The injection pump 703 is a variable frequency booster pump, which can adjust the output pressure according to the testing requirements and adapt to the pressure resistance testing standards of different specifications of faucets C. The injection pump 703 is fixedly connected to the workbench 2 through a mounting bracket (not shown in the figure) to ensure stability during operation.

[0053] (iv) Synchronous drive rod 3 Please see Figures 2-4 The synchronous drive rod 3 is slidably mounted on the worktable 2 along the distribution direction of multiple detection stations J (i.e., the first direction X). For example, the worktable 2 is provided with two guide seats, and the two ends of the synchronous drive rod 3 pass through the two guide seats respectively to achieve sliding guidance. The synchronous drive rod 3 can be made of seamless steel pipe, which has high strength and good straightness, and can withstand the reaction force of multiple sets of swing clamping parts 5 to ensure the stability of synchronous drive. The synchronous drive rod 3 is rotatably connected to the compensation block 504 in each set of swing clamping parts 5 through a pin, and can drive multiple swing clamping parts 5 to swing simultaneously through linear motion to realize the synchronous clamping or release of multi-station faucets C.

[0054] (v) Drive locking component 4 The drive locking component 4 is used to drive the synchronous drive rod 3 to perform linear reciprocating motion and can lock the synchronous drive rod 3 when the drive stops. In this embodiment, the drive locking component 4 is a locking cylinder, which is fixedly mounted on the worktable 2 by a fixing bracket. Its piston is fixedly connected to one end of the synchronous drive rod 3 by a coupling. The locking cylinder is a cylinder with a self-locking function. After the cylinder piston rod extends or retracts to the designated position, it can automatically lock the position to prevent the synchronous drive rod 3 from shifting during the detection process and ensure clamping stability. The locking cylinder is made of aluminum alloy, combined with a stainless steel piston rod, which takes into account both lightweight and corrosion resistance.

[0055] II. Working Principle of Each Component Loading stage: Place multiple faucets C to be tested into the positioning slots 5011 of each testing station J, aligning the liquid inlet C1 of faucet C with the top of the injection pipe 702, and position the switch handle C3 between the two push rods 604. At this time, all components on each testing station J are in the correct position. Figures 7-9 The status shown; Synchronous clamping stage: The drive locking component 4 (locking cylinder) is activated, and its piston rod extends, pushing the synchronous drive rod 3 to move linearly along the length direction (first direction X) of the worktable 2; the synchronous drive rod 3 drives the compensation block 504 of each group of detection stations J to slide in the groove of the transmission block 503 through the pin shaft. Since the sliding direction of the compensation block 504 is inclined with the movement direction of the synchronous drive rod 3, it pushes the swing clamp 502 to swing around the rotating shaft 5022 towards the fixed clamp 501, and finally makes the mating groove 5021 cooperate with the positioning groove 5011 to realize the synchronous clamping and fixing of multiple faucets C.

[0056] During the switch-on phase: As the swing clamp 502 approaches the faucet C, the force rod 9 fixed on the swing clamp 502 moves in an arc, driving the transmission rod 8 to move away from the faucet C. This, in turn, pushes the sliding seat 603 to slide along the sliding track 602. The two push rods 604 simultaneously push the switch handle C3 of the faucet C, opening the switch handle C3. During this process, the sliding seat 603 drives the connecting seat 13 to move synchronously. The inclined surface of the locking block 14 contacts and is squeezed against the locking seat 12, partially retracting into the connecting groove 1301, and the second elastic element 15 is compressed. When the sliding seat 603 moves to the fully open position, the locking block 14 aligns with the locking groove 1201 on the locking seat 12, and is pushed into the locking groove 1201 by the second elastic element 15, thus locking the sliding seat 603 and ensuring that the switch remains open during the detection process. At this time, the de-energized electromagnet 16 is in a de-energized state, attracting the metal block 18 on the locking seat 12. The third elastic element 17 is stretched, and the locking seat 12 remains fixed. At this time, each component on each detection station J is in a state of... Figure 11 The status shown.

[0057] Liquid injection testing phase: The injection pump 703 is started, and the injection pump 703 injects the test liquid from the test tank 1 into the inlet C1 of each faucet C through the injection pipe 702 at a preset pressure. The water flows through the embedded filter inside the faucet C and is discharged from the outlet C2. The testing personnel determine whether the faucet C is qualified by observing the following two indicators: ① Observe whether there is water leakage at non-outlet locations of the faucet C (such as valve body connections, inlet C1 connection points, etc.) to determine the sealing effect; ② Observe the liquid discharge status and whether the embedded filter has fallen off to determine the filter's pressure resistance.

[0058] Upon completion of the inspection: The injection pump 703 is turned off, and the de-energized electromagnet 16 is energized to remove its attraction. At this time, the locking seat 12 moves towards the bracket 601 under the pulling force of the third elastic element 17, and the locking block 14 exits from the locking groove 1201. Subsequently, the piston rod of the control drive locking element 4 (locking cylinder) retracts, pulling the synchronous drive rod 3 to move in the opposite direction. Through the compensation block 504, the swing clamp 502 swings around the rotating shaft 5022 away from the fixed clamp 501, releasing the faucet C. At this time, through the restoration of deformation of the first elastic element 10 or the cooperation of the force rod 9 and the displacement groove 11, the sliding seat 603 moves towards the faucet C, causing the two push rods 604 to reset and the faucet C switch to be turned off. The inspector can then remove the inspected faucet C, completing a multi-station synchronous inspection process.
