For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In view of the shortcomings of the prior art, this embodiment provides a liquid metal adhesion test device, which can be specifically described as follows:

[0040] As shown in the attached drawings 1 and Figure 4The present invention shows a liquid metal adhesion test device, which includes a test tank 1, a tank cover 2, a cavity 3 and a plurality of rubber fixing tubes 5. Liquid metal 11 is arranged inside the test tank 1, and a heater is arranged inside the test tank 1 for heating the liquid metal 11 to prevent the liquid metal 11 from solidifying. A tank cover 2 is arranged on the top of the test tank 1, and the tank cover 2 is used to fix a test rod 4 to perform an adhesion test of the liquid metal 11. The tank cover 2 is also used to cover or open the opening of the test tank 1. A plurality of through holes 21 are also arranged inside the tank cover 2, and the inside of the through holes 21 is used to insert the test rod 4. A cavity 3 is arranged inside the tank cover 2, and the cavity 3 is connected to the plurality of through holes 21. A plurality of rubber fixing tubes 5 are arranged inside the cavity 3, and the rubber fixing tubes 5 are connected to the top wall and the bottom wall of the cavity 3. The plurality of rubber fixing tubes 5 correspond to the plurality of through holes 21 one by one and are coaxially arranged. The outer diameter is larger than the diameter of the through hole 21, so that the interior of the cavity 3 is in a closed state. When the test rod 4 is inserted into the through hole 21, the test rod 4 will also be inserted into the inside of the rubber fixing tube 5. The inner diameter of the rubber fixing tube 5 is smaller than the diameter of the test rod 4, so that the inner wall of the rubber fixing tube 5 squeezes the outer surface of the test rod 4, thereby fixing the test rod 4; through the above-mentioned device, it is only necessary to insert the test rod 4 into the rubber fixing tube 5 to complete the fixation of the test rod 4, and there is no need to rotate the test rod 4, so that the test rod 4 can be quickly installed, thereby improving the efficiency of the test; further, when the test rod 4 needs to be disassembled, it is only necessary to directly pull out the test rod 4, and there is no need to reversely rotate the test rod 4, so that the thread of the test rod 4 is disengaged from the thread on the tank cover 2; through the above-mentioned device, the test rod 4 can be quickly installed and disassembled, which effectively improves the efficiency of the test.

[0041] As attached Figure 3 and attached Figure 4 As shown, a connecting pipe 22 is provided inside the tank cover 2, one end of the connecting pipe 22 is connected to the cavity 3, and the other end is connected to an external pressure pump; the external pressure pump transports air to the cavity 3 through the connecting pipe 22, so that the pressure inside the cavity 3 increases, so that the air inside the cavity 3 squeezes the rubber fixing tube 5, so that the rubber fixing tube 5 shrinks toward the middle to squeeze the test rod 4, and further strengthens the friction between the inner wall of the rubber fixing tube 5 and the test rod 4, which can effectively fix the test rod 4 and prevent the test rod 4 from being separated from the rubber fixing tube 5; when the test rod 4 needs to be disassembled, the air inside the cavity 3 is extracted by the pressure pump, so that the rubber fixing tube 5 returns to its initial state, and then the test rod 4 can be pulled out manually.

[0042] In one embodiment of the present application, the inner diameter of the rubber fixing tube 5 is smaller than the diameter of the through hole 21, and the outer diameter of the rubber fixing tube 5 is larger than the diameter of the through hole 21, so that the rubber fixing tube 5 can close the connection between the cavity 3 and the through hole 21, so that an independent and closed space is formed inside the cavity 3, and the interior of the cavity 3 is connected to the external pressure pump only through the connecting tube 22; when the test rod 4 is inserted, since the inner diameter of the rubber fixing tube 5 is smaller than the diameter of the through hole 21, the top wall of the test rod 4 will abut against the bottom wall of the rubber fixing tube 5, which makes it inconvenient to insert the test rod 4. In the present application, by setting a chamfer at the bottom of the rubber fixing tube 5, the test rod 4 can be quickly inserted into the interior of the rubber fixing tube 5 under the action of the chamfer.

[0043] Furthermore, the chamfer at the bottom of the rubber fixing tube 5 is located close to the inner wall of the rubber fixing tube 5 , and the bottom wall of the rubber fixing tube 5 is still a plane, which is convenient for connecting with the bottom wall of the cavity 3 to seal the cavity 3 .

[0044] As attached Figure 1 and attached Figure 2 As shown, the liquid metal adhesion test device also includes a pulling component 6. The test tank 1 is arranged on the test platform or on the ground. A support frame is arranged on the surface of the test platform or on the ground. The pulling component 6 is arranged on the support frame and is located on the top of the tank cover 2. The pulling component 6 is connected to the tank cover 2 and is used to pull the tank cover 2. The liquid metal 11 adhesion test is carried out by pulling the tank cover 2 and the test rod 4, and adjusting the pulling speed of the test rod 4 to study the thickness of the liquid metal 11 adhered to the outer surface of the test rod 4 under different speeds; the test rod 4 is pulled by the pulling component 6, and the lifting speed of the test rod 4 is adjusted to achieve the purpose of the test.

[0045] In this application, an embodiment is shown in the attached Figure 2 As shown, the lifting assembly 6 includes a lift, a pull rope 61 and a guide assembly. The lift is arranged on a support frame and is located at the top of the tank cover 2. A pull rope 61 is arranged on the top wall of the tank cover 2. The end of the pull rope 61 away from the tube is arranged on the lift. The lift lifts the tank cover 2 and the test rod 4 through the pull rope 61. A guide assembly is also arranged on the support frame and is located at the top of the tank cover 2. It is used to guide and limit the pull rope 61 to prevent the pull rope 61 from shaking and affecting the adhesion of the liquid metal on the test rod 4.

[0046] Furthermore, the lifter may be an electric telescopic rod, a hydraulic telescopic rod, or a motor and a lead screw, or other devices that can be used for lifting objects.

[0047] The guide assembly includes two first guide wheels 62, which are rotatably set on the support frame and located on the top of the tank cover 2. The two first guide wheels 62 are symmetrically arranged with each other. The pull rope 61 is located between the two first guide wheels 62, and the projection of the midpoint between the two first guide wheels 62 on the tank cover 2 overlaps with the connection point of the pull rope 61 on the tank cover 2, that is, the pull rope 61 between the two first guide wheels 62 and the tank cover 2 is in a vertical state with the upper surface of the tank cover 2, so as to ensure that the pull rope 61 located at the lower end of the first guide wheel 62 is in a vertical lifting movement, thereby avoiding shaking of the tank cover 2 and the test rod 4.

[0048] In one embodiment of the present application, the lifting assembly 6 also includes two second guide wheels 63 and a speed change assembly. The two second guide wheels 63 are rotatably arranged on the support frame and are located on the top of the first guide wheel 62. The two second guide wheels 63 are symmetrically arranged with each other. The pull rope 61 is located between the two second guide wheels 63. The two first guide wheels 62 and the two second guide wheels 63 are symmetrically arranged up and down, so that the position between the two first guide wheels 62 corresponds to the position between the two second guide wheels 63. The part of the pull rope 61 between the first guide wheel 62 and the second guide wheel 63 is in a vertical state. A speed change assembly is arranged between the first guide wheel 62 and the second guide wheel 63. The speed change assembly cooperates with the pull rope 61 to change the lifting speed of the pull rope 61.

[0049] Specifically, the speed change assembly includes an electric telescopic rod 64 and a roller 65. The electric telescopic rod 64 is arranged between the first guide wheel 62 and the second guide wheel 63 and is located on one side of the first guide wheel 62. The roller 65 is rotatably arranged at the protruding end of the electric telescopic rod 64. Under the action of the electric telescopic rod 64, the roller 65 contacts the pull rope 61 and is used to support the pull rope 61. During the experiment, it is necessary to change the lifting speed of the pull rope 61 according to the lifting height to study the adhesion performance of the liquid metal 11 under different lifting speeds of the test rod 4. The present application sets the electric telescopic rod 64 on one side of the pull rope 61. While the pull rope 61 is lifted, the electric telescopic rod 64 is evenly extended. The protruding end of the electric telescopic rod 64 supports the pull rope 61 and cooperates with the action of the elevator (the elevator is lifted and lowered at a steady speed at this time). The lifting speed of the pull rope 61 can be increased to achieve the purpose of the experiment.

[0050] Furthermore, in the initial state, the roller 65 of the electric telescopic rod 64 holds the pull rope 61, and the electric telescopic rod 64 is in a semi-extended state, so that the two ends of the pull rope 61 located between the first guide wheel 62 and the second guide wheel 63 are in an inclined state; when it is necessary to increase the speed of the pull rope 61, the electric telescopic rod 64 can be started to extend it at a uniform speed and hold the pull rope 61; when it is necessary to reduce the speed of the pull rope 61, the electric telescopic rod 64 can be started to retract it at a uniform speed so that the length of the pull rope 61 is released, which can effectively reduce the lifting speed of the pull rope 61; the electric telescopic rod 64 can be used to effectively control the lifting speed of the pull rope 61 to achieve the purpose of the test.

[0051] In one embodiment of the present application, the outer surfaces of the first guide wheel 62, the second guide wheel 63 and the roller 65 are all provided with guide grooves, which cooperate with the pull rope 61; by placing the pull rope 61 inside the guide groove, the first guide wheel 62, the second guide wheel 63 and the roller 65 can be prevented from being separated from the pull rope 61.

[0052] As attached Figure 3 As shown, a lifting ear 23 is provided on the top of the tank cover 2, and a hook 7 is provided on the end of the pull rope 61 close to the tank cover 2, and the hook 7 cooperates with the lifting ear 23; by providing the lifting ear 23 and the hook 7, the disassembly and installation of the pull rope 61 and the tank cover 2 are facilitated, thereby improving the convenience of installation before the test and disassembly after the test.
