Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator temperature control, and more specifically to a refrigerator temperature zone temperature controller. Background Art

[0002] Refrigerators, as a commonly used fresh-keeping equipment, can be seen everywhere in life. Among them, the temperature controller is an important control component in the refrigerator for controlling the start and stop of the compressor. The gas or liquid injected into the temperature sensing chamber expands or contracts when the temperature changes, so that the pressure in the temperature sensing chamber changes with the temperature. Through the action of the transmission mechanism, the moving contact and the static contact in the thermostat can automatically connect or disconnect instantly to control the start and stop of the compressor.

[0003] Based on the above, the inventors found that the existing temperature controller consists of a protective cover and a controller, and the controller is mainly connected to the protective cover by bolts. Each time the controller is repaired or replaced, it needs to be installed and removed, and the process is relatively cumbersome. Therefore, in view of this, the existing structure is studied and improved to provide a refrigerator temperature zone temperature controller in order to achieve a more practical purpose.

The present invention provides a clamping assembly, which can quickly install and remove the controller, facilitate the maintenance or replacement of the controller, and provides a synchronization assembly to enable two groups of clamping assemblies to move synchronously in opposite directions, thereby ensuring the coordination and stability of the two groups of clamping assemblies during adjustment.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A refrigerator temperature zone temperature controller, comprising a protective cover, a controller body is centrally arranged inside the protective cover, clamping frames are clamped on both sides of the controller body, a wiring terminal and a sensing terminal are fixedly connected to the top surface and rear end of the controller body respectively, and an adjusting disk is movably connected to the front end of the controller body, a synchronization mechanism is arranged at the lower side of the opposite surfaces of the two clamping frames, a pull rod is fixedly connected to the center of the outer side of the clamping frame, and guide rods are arranged at the four top corners of the outer side of the clamping frame, and a clamping spring is sleeved on the outer side of the guide rod;

[0009] The synchronization mechanism comprises a gear ring, the bottom end of the gear ring is fixedly connected to a support rod, and connecting rods are arranged on both sides of the gear ring, and one end of the connecting rod is fixedly connected to a group of gear blocks on the inner side.

[0010] Furthermore, a pressure-bearing surface is provided at the top of the clamping frame, and the pressure-bearing surface is arranged in an inclined shape.

[0011] Furthermore, the clamping frame and the pull rod are both slidably connected to the protective cover, and the pull rod passes through the side of the clamping frame.

[0012] Furthermore, the guide rod is composed of two sections that are slidably connected, and the outer end surfaces of the two sections of the guide rod are respectively fixedly connected to the inner surface of the protective cover and the clamping frame.

[0013] Furthermore, the clamping spring is fixedly connected to the inner surface of the protective cover and the clamping frame respectively, and the adjustment disk passes through the bottom of the protective cover close to the front end.

[0014] Furthermore, the support rod is movably connected to the center of the bottom of the protective cover, and the gear ring is meshingly connected to the gear block.

[0015] Furthermore, the outer ends of the two connecting rods are fixedly connected to the bottoms of the two clamping frames respectively.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) In this solution, a pressure surface is set on the top of the clamping frame to squeeze the controller body. The clamping frame is forced to move outward, and then the clamping frame is reset under the action of the clamping spring, thereby clamping and fixing the controller body. Conversely, the clamping frame can be separated from the controller body by pulling the pull rod outward, thereby completing the removal of the controller body. Compared with the prior art, the provision of a clamping assembly can quickly install and remove the controller, making it convenient to repair or replace the controller.

[0019] (2) By setting up a synchronization mechanism, the movement of any clamping frame can drive the corresponding connecting rod to move synchronously. Since the gear ring is meshed with the gear block, it drives the gear ring to rotate. The support rod ensures the rotation stability of the gear ring. At the same time, the gear ring cooperates with another set of gear blocks, and finally the two support rods respectively drive the two clamping frames to move synchronously in opposite directions. Compared with the prior art, a synchronization component is set to make the two groups of clamping components move synchronously in opposite directions, thereby ensuring the coordination and stability of the two groups of clamping components during adjustment.

[0029] The synchronization mechanism 7 includes a gear ring 11, the bottom end of which is fixedly connected to a support rod 12, and connecting rods 13 are provided on both sides of the gear ring 11, one end of the connecting rod 13 is fixedly connected to a group of tooth blocks 14 on the inner side, and a synchronization mechanism 7 is provided for the coordination of the movement of the two clamping frames 3.

[0030] See also Figure 3 The top of the clamping frame 3 is provided with a pressure surface, and the pressure surface is arranged in an inclined shape. The controller body 2 is placed into the protective cover 1 from top to bottom, and the bottom surface of the controller body 2 presses the pressure surface at the top of the clamping frame 3.

[0031] See also Figure 3The clamping frame 3 and the pull rod 8 are both slidably connected to the protective cover 1, and the pull rod 8 passes through the side of the clamping frame 3. The clamping frame 3 is forced to move outward, and the movement of the clamping frame 3 compresses the guide rod 9 and the clamping spring 10 at the same time.

[0032] See also Figure 4 The guide rod 9 is composed of two sections connected in a sliding manner, and the outer end surfaces of the two sections of the guide rod 9 are fixedly connected to the inner surface of the protective cover 1 and the clamping frame 3 respectively, and the movement stability of the clamping frame 3 is ensured by the guide rod 9.

[0033] See also Figure 4 The clamping spring 10 is fixedly connected to the inner surface of the protective cover 1 and the clamping frame 3 respectively. The adjusting disk 4 passes through the bottom of the protective cover 1 near the front end until the side of the controller body 2 and the groove on the inner side of the clamping frame 3 are at the same horizontal height. Under the action of the clamping spring 10, the clamping frame 3 is reset, thereby clamping and fixing the controller body 2.

[0034] See also Figure 5 The support rod 12 is movably connected to the bottom center of the protective cover 1, and the gear ring 11 is meshed and connected with the gear block 14. The support rod 12 ensures the rotation stability of the gear ring 11.

[0035] See also Figure 5 The outer ends of the two connecting rods 13 are fixedly connected to the bottoms of the two clamping frames 3 respectively. Since the gear ring 11 is meshed with the gear block 14, when the gear ring 11 rotates, the two support rods 12 respectively drive the two clamping frames 3 to move in opposite directions synchronously.

[0036] When in use: put the controller body 2 into the protective cover 1 from top to bottom, the bottom surface of the controller body 2 squeezes the pressure surface at the top of the clamping frame 3, and the clamping frame 3 is forced to move outward. The movement of the clamping frame 3 compresses the guide rod 9 and the clamping spring 10 at the same time. The guide rod 9 ensures the movement stability of the clamping frame 3 until the side of the controller body 2 and the groove on the inner side of the clamping frame 3 are at the same horizontal height. Under the action of the clamping spring 10, the clamping frame 3 is reset, thereby clamping and fixing the controller body 2. Conversely, the pull rod 8 is pulled outward to separate the clamping frame 3 from the controller body 2, thereby completing the dismantling of the controller body 2. After that, the compressor and the power supply are connected to the terminal 6, and then The protective cover 1 is installed inside the refrigerator, the temperature range is set by the adjustment dial 4, and the internal temperature of the refrigerator is sensed by the sensing end 5. When the internal temperature of the refrigerator deviates from the set temperature, the compressor is started to perform temperature control and regulation. During the installation or disassembly of the controller body 2, the movement of any clamping frame 3 can drive the corresponding connecting rod 13 to move synchronously. Since the gear ring 11 is meshed and connected with the tooth block 14, the gear ring 11 is driven to rotate. The support rod 12 ensures the rotation stability of the gear ring 11. At the same time, the gear ring 11 cooperates with another set of tooth blocks 14, and finally the two support rods 12 respectively drive the two clamping frames 3 to move synchronously in opposite directions, thereby ensuring the coordination and stability of the adjustment of the two clamping frames 3.
