Description

Technical Field

[0001] This utility model belongs to the field of freezer technology and relates to a structure for an adjustable multi-functional rack built into a freezer. Background Technology

[0002] The main body of the built-in shelf in a freezer is a frame structure installed inside the freezer to support and classify items. It is usually made of sturdy and durable materials such as metal and plastic, which have a certain degree of low-temperature resistance. The main body of the built-in shelf in a freezer is usually installed on the inner wall of the freezer by clips.

[0003] In actual use of freezers, since the items to be stored vary in size, it is often necessary to flexibly adjust the height of the main body of the shelf according to the specific specifications of the items to achieve a perfect fit.

[0004] However, the structure of traditional freezer racks is relatively fixed. When adjusting the height, the rack body and the latches are prone to jamming due to structural interference. This not only increases the difficulty of adjustment, but also easily damages the rack body and latches due to forced adjustment, affecting the normal use of the freezer and the service life of the rack body. Therefore, to address the above problems, a built-in adjustable multi-functional rack structure for freezers is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the structure of the traditional freezer rack is relatively fixed. When adjusting the height, the rack body and the buckle are prone to jamming due to structural interference. This not only increases the difficulty of adjustment, but also easily damages the rack body and buckle due to forced adjustment, affecting the normal use of the freezer and the service life of the rack body.

[0006] The adjustable multi-functional shelf structure built into the freezer described in this utility model includes a freezer body. Multiple sets of L-shaped buckles are fixed to both sides of the inner wall of the freezer body. The shelf body is installed in the middle of the multiple L-shaped buckles. An adjustment component is provided in the middle of the shelf body. The middle of the shelf body is hollow.

[0007] The adjustment assembly includes two sets of reinforcing plates, two sets of limiting grooves, a connecting shaft, and four sets of support rods. The two reinforcing plates are respectively fixed to both sides of the main body of the placement frame. The two limiting grooves are respectively opened at the bottom of both ends of the reinforcing plates. One end of the connecting shaft is rotatably connected to the middle of the side of one set of reinforcing plates near the main body of the placement frame. One end of each of the four support rods is fixed to the two sides of the two sets of reinforcing plates that are close to each other.

[0008] The adjustment assembly also includes a worm gear, a drive shaft, and two sets of hollow bearing sleeves. One end of the worm gear is fixed to one end of the connecting shaft, and one end of the drive shaft is fixed to the end of the worm gear away from the connecting shaft. The end of the drive shaft away from the worm gear is rotatably connected to the middle of a set of reinforcing plates away from the connecting shaft. The two hollow bearing sleeves are respectively fixed to the ends of the four sets of support rods that are close to each other.

[0009] The adjustment assembly also includes a rotating head, a bidirectional lead screw, and a worm gear. The rotating head is fixed to the end of the drive shaft away from the reinforcing plate. The middle part of the bidirectional lead screw is rotatably connected to the middle of two sets of hollow bearing sleeves. The worm gear is fixed to the middle of the bidirectional lead screw.

[0010] The adjustment assembly also includes two sets of threaded sliding plates and four sets of rectangular top posts. The two threaded sliding plates are respectively threaded to both ends of the bidirectional lead screw, and the ends of the four rectangular top posts that are close to each other are respectively fixed to the opposite sides of the two sets of threaded sliding plates.

[0011] The adjustment assembly also includes two sets of adjustment plates and four sets of adjustment slides. The two adjustment plates are respectively fixed to one end of the four sets of rectangular top columns that are far apart from each other. The four adjustment slides are respectively fixed to both ends of the two sets of adjustment plates. Reinforcing mechanisms are provided on both sides of the four adjustment slides.

[0012] The four adjustable slide plates are slidably connected to the middle of the four sets of limiting grooves, and the two sides of the four sets of adjustable slide plates are respectively attached to the two sides of the four sets of limiting grooves.

[0013] The worm gear and the worm mesh with each other, and the threads at both ends of the bidirectional lead screw have opposite directions of rotation.

[0014] The reinforcement mechanism includes two sets of reinforcement sliding plates and two sets of reinforcement sliding grooves. The two reinforcement sliding plates are respectively fixed to both sides of each set of adjustment sliding plates, and the two reinforcement sliding grooves are respectively opened on both sides of each set of limiting grooves.

[0015] The two reinforced sliding plates are respectively attached to the sides of the two sets of reinforced sliding grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By adjusting the setting of the components, the flexibility of the main structure of the rack can be improved, reducing the likelihood of jamming due to structural interference when the position of the rack needs to be adjusted. This increases the difficulty of adjustment, requiring operators to spend more time and effort to complete the adjustment work, reducing work efficiency. Moreover, during forced adjustment, irreversible damage to the rack and L-shaped buckle is easily caused, affecting the normal operation and use of the freezer as a whole. It also shortens the service life of the rack, increases the maintenance cost and replacement frequency of the equipment, and brings unnecessary economic losses to enterprises or users.

[0017] By setting up a reinforcement mechanism, the reinforcement groove can support the reinforcement plate when the adjustment plate slides, thereby strengthening the connection between the adjustment plate and the reinforcement plate. This reduces problems such as loosening and shaking that may occur due to the sliding of the adjustment plate, and improves the reliability of the adjustment component. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1 like Figures 1 to 7 As shown, the freezer has an adjustable multi-functional rack structure, including a freezer body 1. Multiple sets of L-shaped buckles 11 are fixed to both sides of the inner wall of the freezer body 1. A rack body 12 is installed in the middle of the multiple L-shaped buckles 11. An adjustment component is provided in the middle of the rack body 12. The middle of the rack body 12 is hollow.

[0032] The adjustment assembly includes two sets of reinforcing plates 2, two sets of limiting grooves 21, a connecting shaft 22, and four sets of support rods 23. The two reinforcing plates 2 are respectively fixed to both sides of the main body 12 of the placement frame. The two limiting grooves 21 are respectively opened at the bottom of both ends of the reinforcing plates 2. One end of the connecting shaft 22 is rotatably connected to the middle of the side of one set of reinforcing plates 2 near the main body 12 of the placement frame. One end of the four support rods 23 is respectively fixed to the two sides of the two sets of reinforcing plates 2 that are close to each other.

[0033] The adjustment assembly also includes a worm gear 3, a drive shaft 31, and two sets of hollow bearing sleeves 32. One end of the worm gear 3 is fixed to one end of the connecting shaft 22, and one end of the drive shaft 31 is fixed to the end of the worm gear 3 away from the connecting shaft 22. The end of the drive shaft 31 away from the worm gear 3 is rotatably connected to the middle of a set of reinforcing plates 2 away from the connecting shaft 22. The two hollow bearing sleeves 32 are respectively fixed to the ends of the four sets of support rods 23 that are close to each other.

[0034] The adjustment assembly also includes a rotating head 4, a two-way lead screw 41, and a worm gear 42. The rotating head 4 is fixed to the end of the drive shaft 31 away from the reinforcing plate 2. The middle part of the two-way lead screw 41 is rotatably connected to the middle part of two sets of hollow bearing sleeves 32. The worm gear 42 is fixed to the middle part of the two-way lead screw 41.

[0035] The adjustment assembly also includes two sets of threaded slide plates 5 and four sets of rectangular top posts 51. The two threaded slide plates 5 are respectively threaded to both ends of the bidirectional lead screw 41, and the ends of the four rectangular top posts 51 that are close to each other are respectively fixed to the sides of the two sets of threaded slide plates 5 that are far apart from each other.

[0036] The adjustment assembly also includes two sets of adjustment plates 6 and four sets of adjustment slides 61. The two adjustment plates 6 are respectively fixed to the ends of the four sets of rectangular top columns 51 that are far apart from each other. The four adjustment slides 61 are respectively fixed to the two ends of the two sets of adjustment plates 6. Reinforcing mechanisms are provided on both sides of the four adjustment slides 61.

[0037] Four adjusting slide plates 61 are slidably connected to the middle of four sets of limiting grooves 21, and the two sides of the four sets of adjusting slide plates 61 are respectively attached to the two sides of the four sets of limiting grooves 21.

[0038] The worm gear 42 meshes with the worm 3, and the threads at both ends of the double-ended lead screw 41 have opposite directions of rotation.

[0039] During operation, when the position of the rack body 12 needs to be adjusted according to the size of the stored food, the rack body 12 can be lifted first to disengage the adjusting plate 6 from the L-shaped buckle 11. Then, the rotating head 4 is rotated to drive the drive shaft 31. The rotation of the drive shaft 31 will drive the worm 3 and the connecting shaft 22 to rotate synchronously. At this time, since the worm 3 and the worm wheel 42 are in a meshed state, the rotation of the worm 3 will drive the worm wheel 42 to rotate. The rotation of the worm wheel 42 will drive the double-acting screw 41 to rotate in the middle of the hollow bearing sleeve 32. At the same time, the rotation of the double-acting screw 41 will drive the two sets of threaded slide plates 5 to move. The movement of the threaded slide plates 5 will drive the rectangular top column 51, the adjusting plate 6, and the adjusting slide plate 61 to move synchronously. When the threaded slide plates 5 move, the movement trajectory of the threaded slide plates 5 can be restricted by the interaction between the rectangular top column 51, the adjusting plate 6, the adjusting slide plate 61, and the limiting groove 21. This causes the two sets of threaded sliding plates 5 to slide in opposite directions at both ends of the bidirectional lead screw 41. While sliding, the threaded sliding plates 5 will drive the rectangular top column 51, the adjusting plate 6, and the adjusting sliding plate 61 to move closer to the center of the shelf body 12, thereby shortening the distance between the two sides of the shelf body 12 and the adjusting plate 6. This makes it easier to remove the shelf body 12 from the L-shaped buckle 11. Then, the shelf body 12 can be placed in the L-shaped buckle 11 at a suitable position, and the rotating head 4 can be rotated in the opposite direction to move the adjusting plate 6 to the sides of the inner wall of the freezer body 1. The hollow design of the shelf body 12 allows cold air to pass more freely between the upper and lower layers of the shelf body 12, reducing the obstruction of cold air circulation caused by tightly stacked items or the shelf body 12. This makes the temperature in each area of ​​the freezer body 1 more uniform, reduces local temperature differences, and ensures that all stored items are in a suitable low-temperature environment, effectively extending the shelf life.

[0040] This step, by adjusting the component settings, can improve the flexibility of the structure of the rack body 12, reducing the likelihood of jamming due to structural interference when adjusting the position of the rack body 12. This increases the difficulty of adjustment, requiring operators to spend more time and effort to complete the adjustment, reducing work efficiency. Moreover, forced adjustment can easily cause irreversible damage to the rack body 12 and L-shaped buckle 11, affecting the normal operation and use of the refrigerator body 1 as a whole. It also shortens the service life of the rack body 12, increases equipment maintenance costs and replacement frequency, and brings unnecessary economic losses to enterprises or users.

[0041] Example 2 like Figures 3-7 As shown, the reinforcement mechanism includes two sets of reinforcement slide plates 9 and two sets of reinforcement grooves 91. The two reinforcement slide plates 9 are fixed to both sides of each set of adjustment slide plates 61, and the two reinforcement grooves 91 are respectively opened on both sides of each set of limiting grooves 21.

[0042] The two reinforced sliding plates 9 are respectively attached to the two sets of reinforced sliding grooves 91 on both sides.

[0043] When the adjusting slide plate 61 slides in the middle of the limiting groove 21 during operation, it will drive the reinforcing slide plate 9 to move synchronously. During the movement, the reinforcing slide plate 9 will slide with the middle of the reinforcing groove 91. With the cooperation of the reinforcing slide plate 9 and the reinforcing groove 91, the stability of the adjusting slide plate 61 when sliding between the reinforcing plates 2 can be enhanced.

[0044] This step, through the setting of the reinforcement mechanism, can strengthen the connection between the adjustment plate 61 and the reinforcement plate 2 by using the support effect of the reinforcement groove 91 on the reinforcement plate 9 when the adjustment plate 61 slides. This reduces the problems of loose connection and shaking that may occur due to the sliding of the adjustment plate 61, thereby improving the reliability of the adjustment component.
