Description

Technical Field

[0001] This utility model relates to the field of refrigerator processing technology, specifically a positioning fixture for processing refrigerator safety doors. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product that keeps food or other items at a constant low temperature. With the continuous development of production and life, refrigerators have become an indispensable household appliance in people's daily lives. However, due to the large size of refrigerators, they often need to be disassembled and processed during the production and processing of refrigerators.

[0003] Patent CN217292081U discloses a novel processing fixture for refrigerator door panels, including a circular platform. The outer wall of the platform has equally spaced, annularly distributed sliding grooves, and each inner wall of one side of the groove has a limiting groove at its center. Sliding blocks are slidably connected inside each groove, and limiting blocks are welded to both sides of the sliding blocks, slidably connected inside the limiting grooves. Although this invention uses a cylinder to drive one sliding block along the groove via a push plate, and the sliding block drives a second positioning post via a first positioning post and a connecting rod, the second positioning post drives a turntable to rotate. At this time, the turntable, via the second positioning post, the connecting rod, and the first positioning post, drives the remaining sliding blocks to slide closer together or separate along the groove, allowing the sliding blocks to clamp and position the refrigerator door panel, significantly improving the stability during processing and making the processed refrigerator door panel easier to disassemble, some drawbacks still exist.

[0004] 1. Although it can rotate and fix the refrigerator door by sliding blocks, there is a major drawback. Because refrigerator doors have various structures, and four sliding blocks can only fix square refrigerator doors when they move at the same time, they cannot fix rectangular structures. Therefore, the above patent has a major problem.

[0005] 2. Since the limiting block moves within the slide groove, as can be seen from the drawings, it is easy for it to get stuck during the movement, requiring repeated manual adjustments, which reduces the efficiency of fixing the refrigerator door. Utility Model Content

[0031] Example 1

[0032] like Figure 1-4 As shown, this utility model provides a technical solution: it includes a worktable 1 and a strip groove 2 formed on the upper end of the worktable 1. The strip groove 2 horizontally extends through the worktable 1. A first adjusting bracket 5 and a second adjusting bracket 6 are provided within the strip groove 2. The two adjusting brackets can be adjusted according to the width of the refrigerator door, such as... Figure 1 and 2 As shown, both sides of the bottom of the operating table 1 are provided with base blocks 3, and an adjustment component 4 is installed on both base blocks 3. The adjustment component can adjust the distance between the two adjustment brackets, such as... Figure 1-3 As shown, the adjusting component 4 is located directly below the strip groove 2. The bottom ends of both the first adjusting bracket 5 and the second adjusting bracket 6 pass through the strip groove 2 and are connected to the adjusting component 4. The adjusting brackets are installed on the adjusting component through the strip groove, which allows for adjustment of the distance between the two adjusting brackets. Figure 1-2 As shown;

[0033] Adjustment assembly 4 includes a support rod 45 fixed inside the base block 3. A stud 41 is located below the support rod 45. The right end of the stud 41 passes through one side of the base block 3 via a bearing, and a control disc 44 is located at its protruding end. By controlling the control disc, the stud can be rotated, such as... Figure 1-2 As shown.

[0034] A blocking block 10 is provided on both sides of the center position of the stud 41. The threads 42 on both sides of the blocking block 10 turn in opposite directions. The bottoms of the first adjusting bracket 5 and the second adjusting bracket 6 are respectively connected to the threads 42 on both sides of the stud 41. The blocking blocks can block the two adjusting brackets and prevent them from disengaging from the threads due to excessive adjustment. Figure 2 As shown.

[0035] A locking nut 43 is installed on the right side of the stud 41. Two locking nuts 43 are provided, located on either side of the base block 3. The locking nuts secure the stud, preventing it from rotating when fixing the refrigerator door. Figure 2 As shown.

[0036] The first adjustment frame 5 and the second adjustment frame 6 are symmetrically arranged, and both have a hollow internal structure to reduce their own weight, making the adjustment smoother. Figure 3 As shown.

A mounting frame 7 is welded to the top of both the first adjusting frame 5 and the second adjusting frame 6. Adjusting plates 8 are slidably connected to the inner sides of the front and rear sides of the mounting frame 7. A placement rack 9 is fixed to the inner side of the ends of the two adjusting plates 8. The two adjusting plates can be adjusted according to the width of the refrigerator door to adapt to refrigerator doors of different widths, such as... Figure 1 , 5 And 6.

[0041] Both the mounting frame 7 and the adjustment plate 8 are rectangular hollow structures, which reduce their own weight and facilitate smooth adjustment. Figure 1 and 5 .

[0042] Bolts 11 are installed on both the front and rear sides of the mounting frame 7. The bolts 11 pass through the limiting holes 12 on the adjusting plate 8, and nuts are screwed onto the bottom ends of the bolts 11. By using the bolts to pass through the adjusting plate, the adjusted plate can be fixed after adjustment, increasing its stability. Figure 1 and 5 As shown.

[0043] The inner side of the shelf 9 has a placement groove, and the inner wall of the placement groove is lined with a protective layer of rubber material to increase the protection of the door. Figure 1 and 5 As shown.

[0044] The inner end face of the placement slot protrudes beyond the inner end face of the mounting frame 7 to prevent collisions between the safety door and the mounting frame during placement. Figure 6 As shown.

[0045] In this embodiment, the two adjustment brackets move within the strip groove, and the spacing is adjusted by the adjustment component to suit refrigerator doors of different sizes. There will be no jamming during the adjustment process, the adjustment is smooth and the work efficiency is improved. With the help of two locking nuts, the two adjustment brackets are firmly fixed to the refrigerator door.

[0046] When in use, loosen the two locking nuts 43 and rotate the control plate 44 to drive the stud 41 to rotate; the bottom of the first adjustment bracket 5 and the second adjustment bracket 6 respectively engage with the threads 42 on both sides of the stud 41, and will rotate with the stud 41 and move towards or away from each other along the strip groove 2 until the distance between the two matches the width of the refrigerator safety door to be processed, then stop rotating the control plate 44.

[0047] Loosen bolt 11 and push the adjusting plate 8 to slide back and forth within the mounting frame 7; when the inner end face of the placement slot of the placement rack 9 matches the length of the refrigerator safety door to be processed, insert bolt 11 into the corresponding limiting hole 12 on the adjusting plate 8, and screw the nut at the bottom of bolt 11 to lock the position of the adjusting plate 8.

[0048] Place the refrigerator safety door to be processed into the placement slots of the two placement racks 9, and use the rubber protective layer on the inner wall of the placement slots to prevent the door from being scratched; rotate the control panel 44 so that the placement rack 9 clamps the refrigerator door, and then tighten the two locking nuts 43 to fix the studs 41, thereby locking the positions of the first adjustment rack 5 and the second adjustment rack 6.
