Description

Technical Field

[0001] The utility model relates to the technical field of faucet detection equipment, in particular to an experimental platform which is convenient for loading and unloading. Background Art

[0002] A faucet is a common name for a water valve, which is a switch used to control the size of the water flow and has the effect of saving water. However, after a long period of use, the faucet will be damaged due to the long-term impact of the water flow on the valve. At this time, the faucet needs to be repaired. After the repair is completed, the faucet also needs to be tested to ensure the integrity of the repair.

[0003] The existing faucet repair experimental platform generally installs the repaired faucet on the mounting seat on the left side of the experimental table, places a bucket on the lower side to collect the water, places a bucket full of water on the upper horn support frame of the experimental table, connects the water inlet pipe of the faucet with the water outlet pipe on the outside of the water tank, observes whether the water pipe is unobstructed and full of water, then presses the faucet valve to observe whether water comes out of the faucet, and at the same time observes whether the faucet operates normally and smoothly, and whether the test is qualified.

[0004] However, in actual use of the above-mentioned platform, when the water pipe and the faucet are connected, a threaded sealing connection is mostly performed through a nut, which requires the staff to perform a rotating operation to complete the sealing connection between the water pipe and the faucet, which takes a long time and is also relatively inconvenient. In addition, when the nut and the faucet are threadedly connected, it is easy to cause wear of the threads on the outside of the faucet, which will affect the sealing of the faucet during subsequent use. In view of this, we propose an experimental platform that is easy to load and unload. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 5As shown, the utility model provides a technical solution: an experimental platform which is easy to load and unload, comprising a test bench 1, a water collecting cylinder is arranged at the right end of the upper surface of the test bench 1, a placing rack 2 is fixedly installed at the left end of the upper surface of the test bench 1, a water tank 3 is arranged on the right side of the placing rack 2, a fixing rack 4 is fixedly installed at the upper end of the test bench 1, a limiting shell 5 is fixedly installed at the center of the upper surface of the fixing rack 4, a circular hole is provided at the inner bottom end of the limiting shell 5, and the bottom end of the faucet can enter the interior of the insertion installation cylinder 602 through the circular hole. The test platform can be suitable for faucets with a sealing ring installed on the outer side of the bottom and a mounting thread opened at the bottom. When the faucet is placed in the limiting shell 5 for water flow detection, the water flowing out of the faucet can be discharged into the water collecting cylinder for collection, and a quick-release assembly is provided on the upper surface of the test bench 1.

[0026] The quick-install assembly includes: an air pump 601, a mounting tube 602, an annular hollow tube 605 and an L-shaped mounting frame 608. The air pump 601 is fixedly mounted on the front end of the upper surface of the test bench 1. The mounting tube 602 is fixedly mounted at the center of the upper surface of the test bench 1 through a support rod. A fixed ring plate 603 is fixedly mounted inside the mounting tube 602. An annular air bag 604 is fixedly mounted on the upper surface of the fixed ring plate 603. The gas delivery end of the air pump 601 is fixedly connected to the outer wall of the annular air bag 604 through a connecting pipe. The connecting pipe passes through the outer wall of the mounting tube 602. The annular hollow tube 605 is fixedly mounted on the inner circle of the upper surface of the fixed ring plate 603. A moving tube 606 is slidably connected to the inner wall of the annular hollow tube 605. An annular cavity is opened in the inner wall of the annular hollow tube 605. The top of the moving tube 606 passes through the annular hollow tube 605. A movable ring plate 607 is fixedly installed, and the outer wall of the movable ring plate 607 fits with the inner wall surface of the installation tube 602, and the top of the annular airbag 604 is fixedly connected to the bottom surface of the movable ring plate 607. When the air pump 601 is started, air can be inflated and discharged into the annular airbag 604. When the annular airbag 604 is inflated, the movable ring plate 607 can be driven to move upward. A rubber pad is fixedly installed on the upper surface of the movable ring plate 607. After the bottom end of the faucet enters the installation tube 602 and is limited, the air pump 601 can be started to inflate the annular airbag 604, driving the movable ring plate 607 to move upward, so that the rubber surface on the movable ring plate 607 fits and seals with the bottom surface of the faucet, thereby preventing water from leaking from the gap between the movable ring plate 607 and the bottom end of the faucet, affecting the detection result.

[0027] However, when the movable ring plate 607 moves upward, it can drive the movable cylinder 606 to move synchronously. At this time, the inner walls of the movable cylinder 606, the annular hollow cylinder 605 and the installation cylinder 602 will limit the expansion direction of the annular airbag 604, so that the annular airbag 604 can better expand upward to push the movable ring plate 607 upward.

[0028] The L-shaped mounting frame 608 is fixedly mounted on the outer surface of the mounting cylinder 602, and an electric push rod 609 is fixedly mounted on the inner surface of the L-shaped mounting frame 608 near the mounting cylinder 602. A limiting rod 610 is fixedly mounted on one end of the electric push rod 609 near the mounting cylinder 602, and one end of the limiting rod 610 near the mounting cylinder 602 passes through the outer wall of the mounting cylinder 602. After the limiting ring on the outer side of the bottom end of the faucet enters the interior of the mounting cylinder 602, the electric push rod 609 can be started to drive the limiting rod 610 to enter the interior of the mounting cylinder 602 and fit the outer wall of the faucet. At this time, the limiting rod 610 and the limiting ring on the outer side of the faucet can limit the faucet to prevent the faucet from escaping from the interior of the mounting cylinder 602. The L-shaped mounting frame 608, the electric push rod 609 and the limiting rod 610 can be arranged in a plurality of groups in a circular array on the outer side of the mounting cylinder 602 to better limit the faucet.

[0029] An arc-shaped groove 701 is provided on the inner wall surface of the upper end of the mounting tube 602, and an arc-shaped clamping plate 702 is fixedly installed on one end of the limiting rod 610 close to the mounting tube 602. The arc-shaped clamping plate 702 is sleeved inside the arc-shaped groove 701, and a protective rubber plate 703 is fixedly installed on the inner wall surface of the arc-shaped clamping plate 702. When the limiting rod 610 moves horizontally, the arc-shaped clamping plate 702 and the protective rubber plate 703 can be driven to move synchronously. The arc-shaped structure of the arc-shaped clamping plate 702 can better adapt to the shape of the faucet, so as to better clamp and limit. The protective rubber plate 703 can avoid hard contact between the arc-shaped clamping plate 702 and the faucet, and avoid unnecessary wear. In the initial state, the arc-shaped clamping plate 702 and the protective rubber plate 703 can be received into the arc-shaped groove 701 to avoid obstruction to the bottom end of the faucet entering the mounting tube 602.

[0030] In the present invention, when the repaired faucet is tested during use, the bottom end of the faucet can be inserted into the interior of the installation tube 602 through the circular hole provided inside the limiting shell 5. When the sealing ring on the outside of the faucet enters the interior of the installation tube 602, the electric push rod 609 is started, and the arc-shaped clamping plate 702 is driven to move to the outside of the faucet and fit through the limiting rod 610. At this time, the arc-shaped clamping plate 702 will cooperate with the sealing ring on the outside of the faucet to limit the faucet, so as to prevent the faucet from being separated from the interior of the installation tube 602 when subjected to an upward force. Subsequently, the air pump 601 is started to inflate the annular airbag 604, thereby pushing up the movable ring plate 607, so that the movable ring plate 607 The rubber surface on the faucet is fitted and sealed with the bottom of the faucet to ensure the sealing when water is passed, and to prevent water from leaking from the gap between the movable ring plate 607 and the bottom of the faucet, which will affect the test results. The installation is completed. When disassembly is required, the electric push rod 609 is started to drive the arc clamping plate 702 to reset, and the air pump 601 is started to extract the gas inside the annular airbag 604 to release the limit on the faucet. All of these can be controlled by PLC with one button operation. There is no need for complicated bolt connections to complete the loading and unloading of the faucet, which improves the experimental efficiency. Subsequently, the water pump is started to draw the water in the water tank 3 into the faucet, and observe whether the faucet is discharging water and whether the faucet operates normally and smoothly.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
