[0030] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0031] As Figures 1 to 5 shown, a leak detection tool for a coupler includes:

[0032] A base 1, provided with a detection station on the base 1 for positioning the lower coupler seat A and coupling the upper coupler seat B to the upper side of the lower coupler seat A;

[0033] A pressing unit 2, provided with a pressing head 21 on the pressing unit 2 for applying a force to the top surface of the upper coupler seat B and making the upper water inlet pipe B1 in the upper coupler seat B connect with the lower water inlet pipe A1 in the lower coupler seat A;

[0037] This detection tooling can simulate installing a coupler with a pumping function on the whole machine (kettle). During the pumping process, it can detect whether there is a water leakage situation, eliminating the cumbersome work of needing to install the whole machine to test, so as to achieve the purpose of quickly detecting leaks. This solution is fast, efficient, highly flexible, and highly versatile.

[0038] It also includes a water storage tank 7. The inner cavity of the water storage tank 7 constitutes a water supply source. The water suction pipe body 32 is communicated with the inner cavity of the water storage tank 7, and the drain pipe body 4 is communicated with the inner cavity of the water storage tank 7; the water storage tank 7 can provide water source, and can recycle the water after testing for circulation use. Moreover, in this embodiment, the water storage tank 7 is placed directly below the detection station. Even if the coupler leaks water during the test, the water storage tank 7 can be used to receive the water.

[0039] Combined with the water storage tank 7, the working principle of this detection tooling is as follows:

[0040] Place the lower coupler seat A and the upper coupler seat B on the detection station and couple them. The pressing head 21 of the pressing unit 2 applies a pressure of the nominal minimum appliance weight of the product downward on the top of the upper coupler seat B (mainly the top of the upper water inlet pipe B1); and initially, the water pipe valve 5 conducts the drain pipe body 4, and then the water pump 3 works, pumps water from the water storage tank 7 and supplies water to the lower water inlet pipe A1 of the lower coupler seat A (pressure 50 kPa - 60 kPa). When the water flows out from the drain pipe body 4 through the upper water inlet pipe B1 of the upper coupler seat B, then close the water pipe valve 5 to cut off the drain pipe body 4. When the water pressure detection meter 6 shows that it reaches 50 kPa, stop supplying water and keep the pressure for 1 minute, so as to observe whether there is a water leakage phenomenon in the coupler.

[0041] The pressing unit 2 includes a fixed part and a movable part connected to each other. The pressing head 21 is connected to the movable part, and the movable part drives the pressing head 21 to move up and down relative to the upper coupler seat B manually, or electrically, or pneumatically.

[0042] And in this embodiment, the pressing unit 2 includes;

[0043] A pad high platform 22, and a hinge seat 23 is fixedly connected to the pad high platform 22;

[0044] The handle 24, the lower part of the handle 24 is fork-shaped and is rotatably hinged to both sides of the hinge seat 23;

[0045] The clamping arm 25, the rear end of the clamping arm 25 is rotatably hinged to the rear end of the hinge seat 23, the front end of the clamping arm 25 is connected with an adjusting bolt 26, and the lower end of the adjusting bolt 26 is connected with a pressing head 21;

[0046] The driving link 27, the driving link 27 is of a U-shaped structure, its upper end is rotatably hinged to the handle 24, and its lower end is rotatably hinged to the rear end of the clamping arm 25.

[0047] In the pressing unit 2, the cushion platform 22 and the hinge seat 23 form a fixed component, and the handle 24, the clamping arm 25 and the driving link 27 form a movable component. The structure is simple, the operation is convenient and fast, and the downward pressing force can be accurately controlled.

[0048] When other embodiments adopt other pressing units 2, a pressure detector for detecting the pressure value applied to the upper coupling seat B is further connected to the pressing unit 2; since during the test, it is necessary to downwardly apply the nominal minimum appliance weight of the product, the simulated weight can be accurately controlled through the pressure detector 8.

[0049] The detection station includes a positioning hole 101, the positioning hole 101 is opened on the base 1, and a locking member 9 is provided on the lower side of the positioning hole 101.

The water storage tank 7 can be detachably placed in the accommodating cavity 102. The pressing unit 2 is fixedly connected to the top surface of the base 1. The water pump 3, the water pipe valve 5 and the water pressure detection table 6 are fixedly connected to the rear end side of the base 1, and a plurality of pipe holes 103 suitable for the front and rear penetration of the water inlet pipe 31, the water extraction pipe 32 and the drain pipe 4 are opened on the rear end wall of the base 1.

The water pipe valve 5 and the water pressure detection table 6 are connected in series on the hard straight pipe 41. The front port of the hard straight pipe 41 is connected to one end of the front section hose 42 through a front joint 44, the other end of the front section hose 42 is connected to the water outlet port of the upper water inlet pipe B1, the rear port of the hard straight pipe 41 is connected to one end of the rear section hose 43 through a rear joint 45, and the other end of the rear section hose 43 is connected to the inner cavity of the water storage tank 7; after the hard straight pipe 41 is pressurized inside the pipe, it will not expand and deform, which helps to fix the water pipe valve 5 and the water pressure detection table 6, and can improve the detection accuracy of the water pressure detection table 6.

[0052] Symmetrically arranged handle openings 104 are provided on the left end wall and the right end wall of the base 1, facilitating testers to carry the detection tooling.

[0053] The pressing head 21 is integrally made of elastic silicone material, or the surface layer of the pressing head 21 is wrapped with elastic silicone material.
