Technical Field

[0001] This utility model relates to the field of refrigerator drawer technology, specifically a refrigerator drawer hanger assembly. Background Technology

[0002] Refrigerators have become an important household item, serving the function of preserving food. To make full use of the internal space of a refrigerator, people usually use drawers and shelves.

[0003] The refrigerator drawer rack assembly and refrigerator disclosed in CN207674812U include two telescopic rods. The front and rear ends of the telescopic rods are equipped with shelf hooks. The telescopic rods are set in a telescopic rod support frame. A drawer sliding rail is provided below the telescopic rod support frame. The drawer is slidably supported on the drawer sliding rail. The telescopic rods include a front rod and a rear rod, which are connected by a tension spring.

[0004] The front and rear rods are connected by a tension spring. After prolonged use, the elasticity of the tension spring will gradually loosen, which means that the adjustment distance between the front and rear rods cannot maintain a relatively stable value after long-term use. To address this, we propose a refrigerator drawer hanger assembly. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a refrigerator drawer hanging bracket assembly. It features a slot on the outer side of the front rod, a movable block with teeth on the outer side of the slot, and a toothed groove on the rear rod that engages with the teeth of the toothed block. The engagement of the toothed block and the toothed groove restricts the movement of the rear rod. A fine-tuning screw adjusts the position of the toothed block within the slot, ensuring a perfect engagement between the teeth of the toothed block and the toothed groove. This guarantees that the adjusted distance between the front and rear rods perfectly matches the spacing of the hanging rods inside the refrigerator.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that the adjustment distance between the front and rear rods of the refrigerator drawer hanger cannot be kept at a relatively stable value after long-term use through the following technical solution.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

Example

[0033] Please see Figure 1 - Figure 6 A refrigerator drawer hanger assembly includes a front rod 1 connected by a bracket, a movable block 5 slidably disposed on the outside of the front rod 1, and a fine-tuning screw 9 for adjusting the position of the toothed block 7 in the slot 6. A rear rod 2 is slidably disposed in the inner slot of the front rod 1. Hanging plates 3 are fixedly disposed on the outside of both the front rod 1 and the rear rod 2. A drawer body 4 is slidably embedded in the bottom of the front rod 1. The drawer body 4 is slidably embedded in the outside of the front rod 1 through a fixed track disposed on the outside of the front rod 1, so that the drawer body 4 can be pulled out after the device is hung on the hanging rod inside the refrigerator.

[0034] The front rod 1 has a slot 6 on its inner side, and a toothed block 7 is slidably arranged in the slot 6. The teeth of the toothed block 7 protrude from the slot 6 and are located in the inner groove of the front rod 1. The outer side of the toothed block 7 is fixedly arranged on the side of the movable block 5 near the front rod 1. The rear rod 2 has evenly distributed toothed grooves 8 on the side near the slot 6. The toothed grooves 8 and the teeth of the toothed block 7 are engaged. The toothed grooves 8 are located in the middle section of the rear rod 2 to ensure that both ends of the rear rod 2 are engaged with the inner groove of the front rod 1. This ensures that the rear rod 2 will not shake when it slides inside the inner groove of the front rod 1. A fixing plate 10 is provided on the outer side of the slot 6. The fixing plate 10 is fixedly arranged on the outer side of the front rod 1.

[0035] The fine-tuning screw 9 is threaded inside the fixed plate 10 and is rotatably connected to the outside of the movable block 5. The fine-tuning screw 9 is made of plastic, which can prevent the threads of the fine-tuning screw 9 from being corroded by the humid internal environment of the refrigerator, thus ensuring the overall service life of the device. A screwing block 11 is fixedly provided at the end of the fine-tuning screw 9 away from the movable block 5. Furthermore, an auxiliary block 18 perpendicular to the outside of the screwing block 11 is fixedly provided on the outside of the screwing block 11. The auxiliary block 18 facilitates the application of force to the screwing block 11 to drive the fine-tuning screw 9 to rotate.

[0036] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0037] Please see Figure 1 - Figure 6 By setting a slot 6 on the outside of the front rod 1, and setting a movable block 5 with a toothed block 7 on the outside of the slot 6, and setting a toothed groove 8 on the rear rod 2 that engages with the teeth of the toothed block 7, the movement of the rear rod 2 is restricted by the engagement of the toothed block 7 and the toothed groove 8. At the same time, the position of the toothed block 7 in the slot 6 is adjusted by the fine-tuning screw 9, so that the teeth of the toothed block 7 and the toothed groove 8 are perfectly engaged with each other, ensuring that the adjusted distance between the front rod 1 and the rear rod 2 perfectly matches the distance of the hanging rods inside the refrigerator.

[0038] The movable block 5 has a buffer opening 12 on its outer side. When the rear rod 2 moves, the teeth in the tooth groove 8 will continuously squeeze the teeth of the tooth block 7, thereby causing the movable block 5 to bend outward. The buffer opening 12 can improve the flexibility of the movable block 5 at the buffer opening 12, thus allowing the movable block 5 to bend at the buffer opening 12 and reducing the difficulty of bending the movable block 5. The front rod 1 has a sliding opening 13 on its outer side. The sliding opening 13 is located at the movable block 5 and is not connected to the slot 6. A protrusion 14 is fixed on the side of the movable block 5 near the sliding opening 13. The slide is slidably connected to the inside of the slide 13. Furthermore, symmetrically distributed grooves 15 are provided inside the slide 13. The grooves 15 are located on the upper and lower sides inside the slide 13. At the same time, the shape of the upper and lower sides of the protrusion 14 inside the slide 13 can be set to fit into the groove 15, ensuring the stability of the protrusion 14 when sliding inside the slide 13. This also prevents the protrusion 14 from being dislodged from the slide 13 when the movable block 5 is bent by force, thereby preventing the connection between the fine-tuning screw 9 and the movable block 5 from being broken by bending stress.

[0039] In addition, such as Figure 4 As shown, symmetrically distributed reinforcing blocks 16 are fixed on the outer side of the movable block 5. The reinforcing blocks 16 are located on the side where the movable block 5 is connected to the fine-tuning screw 9. The setting of the reinforcing blocks 16 can improve the bending strength of the movable block 5.

[0040] It is worth noting that the outer end of the teeth of the tooth block 7 faces the tail end of the front rod 1, and the outer end of the teeth in the tooth groove 8 faces the head end of the front rod 1. This ensures that when the tooth block 7 is embedded in the tooth groove 8, it cannot pull the rear rod 2 outward directly, thus fixing and limiting the position of the rear rod 2. However, pushing the rear rod 2 inward will not be affected. This makes it convenient to push the rear rod 2 directly until the hanging plate 3 is hung on the hanging rod inside the refrigerator when adjusting the position of the rear rod 2, thus realizing the quick installation of the refrigerator drawer and hanging rack assembly.

[0041] The following describes the installation method of the refrigerator drawer and the hanging rack according to the embodiments of this application:

[0042] First, push the movable block 5 outward to retract the teeth of the toothed block 7 into the slot 6, and then pull the rear rod 2 outward.

[0043] Then, the drawer body 4 is slidably inserted into the outside of the front rod 1 via the fixed track set on the outside of the front rod 1;

[0044] Next, push the rear lever 2 inward until the two hanging plates 3 on the device are hooked onto the hanging rod inside the refrigerator;

[0045] Finally, by turning the fine-tuning screw 9 by turning the screw block 11, the movable block 5 and the toothed block 7 move back and forth in the slot 6, aligning the toothed block 7 with the teeth in the toothed groove 8, ensuring that the teeth of the toothed block 7 are perfectly embedded in the toothed groove 8, thereby fixing the position of the rear rod 2 in the device, and precisely adjusting the distance between the inner sides of the two hanging plates 3 to perfectly match the distance between the hanging rods in the refrigerator.

[0046] Because both the teeth of the toothed block 7 and the toothed groove 8 have a tooth-to-tooth width, when the hanging plate 3 is hung on the hanging rod inside the refrigerator, if the teeth of the toothed block 7 cannot be perfectly fitted into the toothed groove 8, the slight width between the teeth will cause the toothed block 7 to have room to wobble within the toothed groove 8. At this time, when the device is subjected to external force, the rear rod 2 will wobble within the front rod 1, generating noise. The fine-tuning screw 9 in this technical solution can adjust the position of the toothed block 7 when the teeth of the toothed block 7 cannot be perfectly fitted into the toothed groove 8, so that the teeth of the toothed block 7 are perfectly fitted into the toothed groove 8, thereby avoiding the occurrence of wobbling.

[0047] In the implementation of this technical solution, such as Figure 1 and Figure 4 As shown, an auxiliary plate 17 is fixedly provided on the outside of the movable block 5. The auxiliary plate 17 is located on the side of the movable block 5 away from the fine-tuning screw 9. When the inner rod is pulled outward and the movable block 5 needs to be moved, the movable block 5 can be moved by the auxiliary plate 17, which makes it convenient for personnel to apply force.

[0048] In the implementation of this technical solution, such as Figure 3 and Figure 4 As shown, in order to ensure that the movable block 5 slides straight, there are limit blocks 19 on both the upper and lower sides of the movable block 5. The limit blocks 19 are fixed to the outer side of the front rod 1. The movable block 5 is clamped by the limit blocks 19, and the sliding trajectory of the movable block 5 is restricted between the two limit blocks 19, thereby ensuring that the movable block 5 slides straight and stable.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
