Description

Technical Field

[0001] The utility model relates to the technical field of temperature controller testing, in particular to a commercial refrigerator temperature controller testing device. Background Art

[0002] Commercial refrigerators are widely used in the food, medicine and other industries. One of their core components is the temperature controller, which is responsible for maintaining the temperature inside the cabinet within the set range. The performance of the temperature controller directly affects the preservation effect and energy consumption of the refrigerator. When testing the traditional refrigerator thermostat performance test device, it is necessary to connect the metal connecting plate on the refrigerator thermostat to the refrigeration compressor in the refrigeration device through a wire. Although an electric clamp can be set at one end of the wire to improve the connection efficiency between the refrigeration compressor and the refrigerator thermostat, the electric clamp also needs to be clamped and connected one by one, thereby reducing the operating efficiency when testing the refrigerator thermostat performance.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN219916223U proposes a refrigerator temperature control performance test device, which inserts the metal connecting plate at the bottom of the refrigerator thermostat to be tested into the socket on the connecting socket, and then closes the pressure plate to make the two buckles engage with the rectangular bayonet, and the refrigerator thermostat is pressed and fixed by the bottom end surface of the clamping plate to avoid loosening of the refrigerator thermostat during the test, thereby improving the reliability and operating efficiency of the performance test device during the test.

[0004] However, although the above-mentioned refrigerator temperature control performance testing device can improve the reliability and operating efficiency of the performance testing device during testing by plugging the metal connecting plate at the bottom of the refrigerator thermostat into the socket on the connecting socket and limiting it by the pressure plate, when the refrigerator temperature control performance testing device fixes the refrigerator thermostat, the clamping mechanism can only clamp and fix refrigerator thermostats of a single size, resulting in a problem of a low application range of the device.

[0033] Specifically, the socket 12 is connected to the connecting piece at the bottom of the thermostat body 13, and then the driving mechanism 9 is used to drive the two rotating plates 17 to rotate relative to each other along the first rotating shaft 21, so that the two rotating plates 17 drive the two clamping plates 14 to rotate relative to each other, thereby realizing the clamping and positioning of the thermostat body 13. Since the clamping plate 14 is an arc-shaped structure, the clamping plate 14 can clamp and fix thermostat bodies 13 of different sizes when rotating, thereby ensuring the stability of the thermostat body 13 and improving the application range of the device, and solving the problem that the existing refrigerator thermostat testing device has a low application range when fixing the refrigerator thermostat because the clamping mechanism can only clamp and fix refrigerator thermostats of a single size.

[0034] It should be noted that, in this embodiment, the testing method of the thermostat body 13 can refer to the Chinese patent with announcement number CN219916223U. This is a prior art and will not be described in detail here. This embodiment aims to improve the applicability of the device for clamping and fixing different thermostat bodies 13.

The two second rotating shafts 91 are respectively connected to the two first rotating shafts 21 through a belt transmission mechanism 92. A worm gear mechanism 94 is arranged in the fixed frame 10 and is used to drive the second rotating shafts 91 to rotate. In the present embodiment, a rotating groove 16 for rotating the rotating plate 17 is penetrated in the fixed frame 10. Specifically, the worm wheel of the worm gear mechanism 94 is sleeved on one of the second rotating shafts 91, and the worm is meshed with the worm wheel and rotatably arranged on the fixed frame 10, and the control end of the worm extends outside the fixed frame 10. The worm gear mechanism 94 drives one of the second rotating shafts 91 to rotate, so that the two gears 93 rotate relatively, so that the two first rotating shafts 21 rotate relatively under the drive of the belt transmission mechanism 92, thereby realizing the relative rotation of the two clamping plates 14.

[0036] like Figures 3 to 6 As shown, in this embodiment, the socket 12 is slidably arranged on the fixed frame 10, a slider 19 is provided at the bottom of the socket 12, a slide groove 15 for the slider 19 to slide is provided through the fixed frame 10, the width of the socket 12 is greater than the width of the slide groove 15, and a plurality of limiting holes 20 are provided along the length direction of the slide groove 15, the slider 19 is relatively provided with a limiting mechanism 8 that can limit the limiting hole 20, and movable grooves 84 are provided on both sides of the slider 19, and the limiting mechanism 8 includes:

[0038] The spring 83 is fixedly connected to the second end of the movable plate 82 and is located in the movable groove 84. Specifically, in the present embodiment, the limiting mechanism 8 has two groups and is relatively arranged along the slider 19. By pressing the pressing block 81 to push the movable plate 82 to move, the movable plate 82 squeezes the spring 83, and at the same time, the movable plate 82 drives the limiting rod 85 to move into the movable groove 84 and releases the limiting of the limiting hole 20, thereby realizing the movement of the slider 19 and the socket 12, facilitating the connection between the socket 12 and the thermostat body 13, and improving the use range of the device.

[0039] like Figure 3 and Figure 4 As shown, in this embodiment, an anti-slip pad 18 is fixedly connected to the end surface of the clamping plate 14 facing the socket 12 .

[0040] like Figure 1As shown, in this embodiment, a temperature monitoring mechanism 4 is fixedly connected to the base 1, a monitoring probe 5 is provided on the temperature monitoring mechanism 4, a control mechanism 6 for controlling the temperature monitoring mechanism 4, a lifting mechanism 7 and a refrigeration device 3 is fixedly connected to the base 1, and a plurality of universal wheels 11 with brakes are fixedly connected to the bottom of the base 1.

[0041] Working principle:

[0042] By connecting the socket 12 with the connecting piece at the bottom of the thermostat body 13, and then driving one of the second rotating shafts 91 to rotate through the worm gear mechanism 94, the two gears 93 rotate relative to each other, so that the two first rotating shafts 21 rotate relative to each other under the drive of the belt transmission mechanism 92, so as to realize the relative rotation of the two clamping plates 14, thereby realizing the clamping and positioning of the thermostat body 13. Since the clamping plate 14 is an arc structure, the clamping plate 14 can clamp and fix thermostat bodies 13 of different sizes when rotating, thereby ensuring the stability of the thermostat body 13 and improving the application range of the device, and solving the problem that when the existing refrigerator thermostat testing device fixes the refrigerator thermostat, the clamping mechanism can only clamp and fix the refrigerator thermostat of a single size, thereby causing the device to have a low application range.
