Hinges are also used to install refrigerator doors on household refrigerators. Refrigerators are important tools for storing food. In order to improve the space utilization efficiency of refrigerators, refrigerator doors will also have shelves. Therefore, when producing refrigerator hinges, in addition to considering the weight of the refrigerator door itself, it is also necessary to consider the weight of the items placed. In the prior art, the torque test of refrigerator hinges generally directly tests the rotational bearing capacity of the hinge. During the test, the upper limit of the bearing is tested by increasing the bearing gravity on the object connected to the hinge. This is generally achieved by adding a counterweight block, and it is difficult to make detailed adjustments when adding the counterweight.

During the test, personnel need to manually push, pull and open and close the frame multiple times. Long-term repetitive pushing, pulling and opening and closing can easily consume a lot of physical strength of personnel and increase their work intensity. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a refrigerator door hinge angle torque testing device, including: a fixed seat 1, the outer surface of the fixed seat 1 is fixedly connected with a mounting frame 2, the top of the mounting frame 2 is fixedly connected with a motor 3, the output end of the motor 3 rotates and passes through the top of the mounting frame 2, the output end of the motor 3 is fixedly connected with a turntable 4, the bottom of the turntable 4 is fixedly connected with a first fixed rod 5, the outer surface of the first fixed rod 5 is rotatably connected with a connecting block 6, the inner surface of the connecting block 6 is rotatably connected with a second fixed rod 7, the bottom of the second fixed rod 7 is fixedly connected with a second mounting block 14, the outer surface of the second mounting block 14 is fixedly connected with a mounting plate 11, the front surface of the fixed seat 1 is fixedly connected with a fixed plate 10, the fixed plate 10 and the mounting plate 11 are matched, and the rear surface of the fixed seat 1 is fixedly connected with a counterweight assembly 9; the counterweight assembly 9 includes a water tank 901 and a second counterweight box 906, the water tank 901 is fixedly connected to the rear surface of the fixed seat 1, and the water tank 901 is fixedly connected to the rear surface of the fixed seat 1. A pump body 902 is arranged at the inner bottom, a water pipe 903 is arranged at the top of the pump body 902, an outer surface of the water pipe 903 is fixedly connected to the rear surface of the second counterweight box 906 away from the pump body 902, and the second counterweight box 906 is fixedly connected to the outer surface of the mounting plate 11, a return pipe 904 is arranged at the bottom of the second counterweight box 906, an outer surface of the return pipe 904 is fixedly connected to the outer surface of the water tank 901 away from the second counterweight box 906, the pump body 902 and the water pipe 903 are connected, the second counterweight box 906 and the return pipe 904 are connected, a valve 905 is arranged on the outer surface of the return pipe 904 away from the second counterweight box 906, and the valve 905 and the return pipe 904 are connected, a first mounting block 13 is fixedly connected to the outer surface of the mounting plate 11, a connecting piece 12 is fixedly connected to the outer surface of the fixing plate 10, and the dial 15 and the connecting piece 12 are matched.

[0024] The effect achieved by the entire embodiment 1 is that when testing the refrigerator door hinge, firstly, two hinge bodies in a group are fixedly installed on the outer surfaces of the fixing plate 10 and the mounting plate 11 by bolts, so that the two plates can be connected to each other through a group of refrigerator hinge bodies, simulating the application scenario of the hinge in the refrigerator, and then a weightable object is placed in the first weight box 8, which increases the load of the mounting plate 11, so that the two refrigerator door hinge bodies will be pulled downward by a larger gravity, and then the pump body 902 is started, and the pump body 902 will pump the water tank 9 when working. 01 is pumped outward and transported to the second counterweight box 906 through the water pipe 903. At the same time, the water in the second counterweight box 906 can be opened by opening the valve 905, so that the water stored inside it flows into the water tank 901 from the return pipe 904, which plays a regulating role. According to the needs, the second counterweight box 906 can be injected or reduced with a proper amount of water to control the water volume in the second counterweight box 906, so as to accurately control the weight of the counterweight. During the test, in order to simulate the angular torque of the opening and closing of the two refrigerator hinge bodies under the load state, the top of the mounting frame 2 is started The motor 3 is fixedly arranged. When the output end of the motor 3 drives the turntable 4 to rotate forward and reversely, the first fixing rod 5 located at the bottom edge thereof will rotate correspondingly with the inner wall of the connecting block 6, and push and pull the second fixing rod 7 through the connecting block 6. The second fixing rod 7 is fixed to the outer surface of the mounting plate 11 near the top through the second mounting block 14, so that the mounting plate 11 will rotate toward the front side of the fixing plate 10 or away from the fixing plate 10 with the two refrigerator hinge bodies as the axis, thereby playing the role of opening and closing. Under the action of multiple forward and reverse rotations of the output end of the motor 3, When the two refrigerator hinge bodies are under load and subjected to multiple opening and closing tests, if the angle torque is not up to standard, the side fixed on the mounting plate 11 will gradually tilt downward, causing the height of the mounting plate 11 to move downward accordingly, and the second fixing rod 7 will simultaneously slide down on the inner side of the connecting block 6. At this time, when the mounting plate 11 is attached to the front surface of the fixing plate 10, the personnel use the first mounting block 13 to fix the surface of the mounting plate 11 with an observation hole on the surface of the connecting piece 12, and observe the overlap between the connecting piece 12 and the surface of the dial 15 to record the load-bearing capacity and torque size of the refrigerator hinge.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the bottom cross-section of the first fixed rod 5 is larger than its top cross-section. The first fixed rod 5 is located at the bottom of the turntable 4 near one side edge. The outer surface of the mounting plate 11 is fixedly connected to the first counterweight box 8, and the first counterweight box 8 is located below the second counterweight box 906.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, by fixing the first counterweight box 8 on the outer surface of the mounting plate 11, the first counterweight box 8 can be placed with solid objects of higher density, thereby playing a role in quickly increasing the counterweight. Solid objects of higher density, such as metals, will be heavier than water at the same volume, thereby avoiding the use of a single water injection method for counterweighting, and being unable to perform limit tests on refrigerator hinges, thereby improving the use effect of the computer of the refrigerator door hinge angle torque test equipment.

[0027] Working principle: When testing the refrigerator door hinge, the two refrigerator hinge bodies to be tested are respectively fixed on the outer surfaces of the fixing plate 10 and the mounting plate 11 with bolts, and the weightable object is placed in the first weight box 8, which plays a role in increasing the overall weight of the mounting plate 11. Then the pump body 902 is started. When working, the pump body 902 will pump the clean water in the water tank 901 outward and transport it to the second weight box 906 through the water pipe 903. According to needs, the second weight box 906 can be injected or reduced by opening the valve 905 and transporting it to the water tank 901 through the reflux pipe 904, so as to accurately control the weight of the weight. The motor 3 fixed on the top of the mounting frame 2 is started. When the output end of the motor 3 drives the turntable 4 to rotate forward and reversely, the first fixing rod 5 located at its bottom edge will rotate correspondingly with the inner wall of the connecting block 6, and push and pull the second fixing rod 7 through the connecting block 6, so that the mounting plate 11 will rotate toward the front side of the fixing plate 10 with the two refrigerator hinge bodies as the axis. When the hinge 4 is driven by the motor 3 and rotated forward and backward, the hinge 4 is opened and closed for testing.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
