Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators and daily necessities, in particular to a combined refrigerator turntable. Background Art
[0002] The refrigerator turntable is a convenient frame structure installed on the drawer plane of the refrigerator. Its main function is to turn the original refrigerator plane space into a rotating three-dimensional storage space, which is convenient for users to store various items, such as beverage bottles, seasoning jars, vegetables, etc.
[0003] The refrigerator turntable of the prior art can move items as the turntable rotates, so that users can easily take items out of the refrigerator and move the items stored in the back to the front by rotating, without having to search or reach deep into the refrigerator to get things, or take away the items in the front to get the items in the back, or move the whole thing very conveniently. It can not only improve space utilization, but also avoid waste caused by squeezing food. The refrigerator turntable is a convenient and practical refrigerator accessory, which can greatly improve the comfort and efficiency of users using the refrigerator;
[0004] However, under the existing technology, the rotating track design of the refrigerator turntable is very complicated, and the moving structure at the bottom of the turntable is also very complicated, especially the track groove structure that controls the moving path. It is even necessary to set up an additional rotating bracket structure similar to the bottom of the microwave turntable to help rotation and movement. This three-layer structure of tray, rotating bracket and chassis further complicates the product, so we need to redesign the refrigerator turntable to meet basic needs and simplify the structure as much as possible. Summary of the invention
[0005] The utility model aims to overcome the deficiencies of the prior art and provide a double-layer combined refrigerator turntable that meets the requirements of a fast and convenient rotation structure and a simplified product structure.
[0006] The utility model is realized through the following technical scheme: a combined refrigerator turntable comprises a chassis and a storage tray, wherein the storage tray is arranged on the chassis, wherein: a ball bearing foot is arranged at the bottom of the storage tray, a circular rotating rail groove is arranged on the top surface of the chassis, the rotating rail groove is further provided with an inner front and rear rolling rail groove and an outer front and rear rolling rail groove, the inner front and rear rolling rail groove is arranged inside the rotating rail groove, and the outer front and rear rolling rail groove is arranged outside the rotating rail groove; the ball bearing foot at the bottom of the storage tray is arranged in the rotating rail groove so that the storage tray rotates relative to the chassis, and the ball bearing foot can move from the rotating rail groove to the inner front and rear rolling rail groove and the outer front and rear rolling rail groove so that the storage tray translates relative to the chassis.
[0007] By adopting the above technology, firstly, the refrigerator turntable becomes a double-layer structure object with only a chassis and a storage tray, which is greatly simplified compared with the three-layer or four-layer structure of the chassis, storage tray, rotating bracket and ball bearing in the prior art, and is easy to maintain, cheap to make and easy to promote; secondly, the track of the refrigerator turntable is greatly optimized. The multiple cat-ear rolling groove structures assisted by the original very complex inner and outer double-circle rolling groove combination are simplified into rolling grooves of a circular combination linear structure, which makes rotation and translation more direct, and after the storage tray is taken away and put back, the user can quickly align the rolling track groove structure by hand in a blind state, solving the problem of the prior art that the rotating bracket needs to align the bottom groove structure of the storage tray upward and the double-circle rolling groove downward. In addition, because the field of vision inside the refrigerator is limited, the storage tray needs to be made into a transparent structure as much as possible and is difficult to observe, which limits the combination of colors, patterns, etc. of the refrigerator turntable. The present structure overcomes these problems.
[0008] Preferably, a translation control slot is provided at the center of the chassis, an azimuth axis is provided at the center of the bottom of the storage tray, the azimuth axis is inserted into the translation control slot, and rotates and translates within the limit of the translation control slot. With this structure, positioning and movement can be performed more conveniently, and the azimuth axis has a relatively deep length inserted into the translation control slot, which can better prevent the storage tray from falling off the chassis.
[0009] Preferably, a translation hole card is inserted into the translation control slot, a moving slot is provided in the slotted hole inside the translation hole card, and tongues are provided at the head and tail of the moving slot to allow the azimuth axis to be fixed and rotated. With this structure, the azimuth axis can be clamped and positioned at both ends of the tongues at the head and tail of the translation hole card, and then rotated at a certain angle, and the movement of the moving slot can be smooth.
[0010] Preferably, a stop bar protruding from the surface of the storage tray is provided adjacent to the inner front and rear rolling track groove or the outer front and rear rolling track groove. The stop bar can limit the maximum retreat position of the ball bearing foot, so that the storage tray will not hit the rear wall of the refrigerator when it cannot be operated.
[0011] Preferably, a suction cup is provided on the bottom of the chassis, and the suction cup can be adsorbed on the plane of the refrigerator drawer to maintain a fixed position.
[0012] Preferably, the inner front and rear rolling rail grooves are arranged between 22 o'clock and 2 o'clock of the rotating rolling rail groove, and the outer front and rear rolling rail grooves are arranged between 4 o'clock and 8 o'clock of the rotating rolling rail groove, and the arrangement direction is longitudinal. The longitudinal movement of the rolling rails will be smoother.
[0013] Preferably, metal strips are arranged in the rotating rolling track groove, the inner front and rear rolling track groove, and the outer front and rear rolling track groove, and the ball feet are provided with magnetic rings. The magnetic rings can absorb the metal strips and can keep the correct track position to the greatest extent for movement.
[0014] Preferably, the storage tray is made of glass, which is not only clean and sanitary but also relatively transparent and easy to observe.
[0015] Preferably, the storage tray is round or oval in shape. The round tray is easy to rotate, while the oval tray can carry more objects and is convenient for taking objects.
[0016] Compared with the prior art, the utility model has the following advantages: 1. The three-layer structure of the prior art is cleverly simplified into a two-layer structure with only a chassis and a storage tray, and not only the original functions are maintained, but also the requirements for quick and convenient rotation are met; 2. The track of the refrigerator turntable of the prior art is greatly optimized, and the multiple cat-ear rolling groove structures assisted by the original very complex inner and outer double-circle rolling groove combination are simplified into rolling grooves of a circular combination linear structure, making rotation and translation more direct, easy to take, and easy to realign and place.

DETAILED DESCRIPTION
[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] Embodiment 1, as Figures 1 to 5 The combined refrigerator turntable shown in the figure comprises a chassis 1 and a storage tray 2. The storage tray 2 is directly placed on the circular chassis 1 with a radius of 70 cm to 120 cm. The connection between the two components is not completely fixed, but is arbitrarily movable, that is, the storage tray 2 can be easily removed from the upper end of the chassis 1. Figure 2 , 3 As shown, the bottom of the transparent material storage tray 2 is a square with a side length of 30cm~50cm, and a ball foot 3 is set at each of the four corners. The so-called ball foot 3 refers to a common inner cavity set in a metal or plastic box body, in which a marble that can roll arbitrarily is placed. The marble can roll on the contact plane, and this structure can form a structure and function similar to a universal wheel;
[0029] like Figure 6 As shown, the top flat surface of the chassis 1 is concavely provided with a circle of circular rotating track grooves 4, and the width of the rotating track grooves 4 can match the ball diameter of the rolling ball foot 3, as shown in FIG. Figure 6 As shown, the rotating rolling track groove 4 is also integrally provided with an inner front-and-rear rolling track groove 5 and an outer front-and-rear rolling track groove 6 composed of two parallel straight groove bodies. The inner front-and-rear rolling track groove 5 is arranged inside the circular ring structure of the rotating rolling track groove 4, and the outer front-and-rear rolling track groove 6 is arranged outside the circular ring structure of the rotating rolling track groove 4. Specifically, the inner front-and-rear rolling track groove is arranged at 22 points and 2 points of the rotating rolling track groove 4 and extends longitudinally from top to bottom, and the outer front-and-rear rolling track groove 6 is arranged at 4 points and 8 points of the rotating rolling track groove 4 and extends longitudinally from top to bottom. This structure can help the storage tray to perform simple longitudinal movement in addition to 360° free rotation, that is, rotation and longitudinal movement can be switched, and this simple track structure will move longitudinally more smoothly, and there will be no rotation jamming as in the prior art.
[0030] like Figure 5-8 As shown, the ball foot 3 at the bottom of the storage tray 2 is placed in the rotating roller groove 4 so that the storage tray 2 rotates relative to the chassis 1, or moves from the rotating roller groove 4 to the inner front and rear roller grooves 5 and the outer front and rear roller grooves 6 so that the storage tray 2 translates relative to the chassis 1.
[0031] First, the refrigerator turntable has become a double-layer structure object with only a chassis 1 and a storage tray 2, which is greatly simplified compared with the 3-layer and 4-layer structures of the prior art, and is easy to maintain, cheap to make and easy to promote; second, the track of the refrigerator turntable has been greatly optimized. The multiple cat-ear rolling groove structures assisted by the original very complex inner and outer double-circle rolling groove combination have been simplified into rolling grooves of a circular combination linear structure, making rotation and translation more direct, and after the storage tray is taken away and put back, the user can quickly align the rolling track groove structure by hand in a blind state, solving the problem of the prior art that the rotating bracket needs to align the bottom groove structure of the storage tray upward and the complex structure of the double-circle rolling groove downward, and because the field of view inside the refrigerator is limited, the storage tray needs to be made into a transparent structure as much as possible to facilitate observation, which limits the combination of colors, patterns, etc. of the refrigerator turntable. The present structure overcomes these problems.
[0032] Specific usage methods, such as Figure 6-8 Here, we use the oblong storage tray 2 of Example 2 for introduction. Under normal conditions, the structure uses the suction cup of the bottom plate to be adsorbed on the drawer grid of the refrigerator. Various foods are placed on the storage tray 2, and then the ball bearing feet 3 are lifted and aligned with the inner front and rear rolling track grooves 5 and the outer front and rear rolling track grooves 6, so that the bottom plate 1 and the storage tray 2 are combined;
[0033] The requirement 1 is that we need to pull out the storage tray 2, just like Figure 7 As shown, the storage tray is pulled forward from the inner ends of the inner front and rear rolling grooves 5 and the outer front and rear rolling grooves 6, and the ball feet 3 of the storage tray roll upward along the inner front and rear rolling grooves 5 and the outer front and rear rolling grooves 6, so that the storage tray moves out of the chassis, and the two are misaligned, thereby achieving the action of pulling out the storage tray 2;
[0034] Requirement 2: We need the food on the side of tray 2 to be displayed in the right direction, such as Figure 7 In the state, after all the ball feet 3 are in the rotating roller groove 4, we can rotate 90° clockwise, that is, Figure 7-8 state, so that the food on the side of the storage tray 2 can be displayed on the front;
[0035] Requirement 3: We need the food behind tray 2 to be displayed frontally. Based on requirement 2, we can further rotate it 180°, or Figure 6 Just rotate 360° in the state.
[0036] Preferably, a translation control slot 7 is provided at the center of the chassis 1, and an azimuth axis 8 is provided at the center of the bottom of the storage tray 2. The azimuth axis 8 is inserted into the translation control slot 7 and rotates and translates in the limit of the translation control slot 7. With this structure, positioning and movement can be performed more conveniently, and the azimuth axis 8 has a relatively deep length and is inserted into the translation control slot 7, which can better prevent the storage tray 2 from falling off from the chassis 1.
[0037] Preferably, a translation hole card plate 9 is inserted into the translation control slot 7, and a moving slot 10 is provided in the slotted hole inside the translation hole card plate 9, and a tongue 11 is provided at the head and tail of the moving slot 10 to fix the position and rotate the azimuth axis 8. With this structure, the azimuth axis can be clamped and positioned at both ends of the tongue of the head and tail of the translation hole card plate and then rotated at a certain angle, and the movement of the moving slot can be smooth.
[0038] Preferably, a stop bar 12 protruding from the surface of the storage tray 2 is provided adjacent to the inner front and rear rolling track groove 5 or the outer front and rear rolling track groove 6. The stop bar can limit the maximum retreat position of the ball foot, so that the storage tray will not hit the rear wall of the refrigerator when it cannot be operated.
[0039] Preferably, the bottom of the chassis 1 is provided with a suction cup 13. The suction cup can be adsorbed on the plane of the refrigerator drawer to maintain a fixed position.
[0040] Preferably, the inner front and rear rolling rail grooves are arranged between 22 o'clock and 2 o'clock of the rotating rolling rail groove 4, and the outer front and rear rolling rail grooves 6 are arranged between 4 o'clock and 8 o'clock of the rotating rolling rail groove 4, and the arrangement direction is longitudinal. The longitudinal movement of the rolling rails will be smoother.
[0041] Preferably, metal strips are arranged in the rotating rolling track groove 4, the inner front and rear rolling track groove 5, and the outer front and rear rolling track groove 6, and the ball foot 3 is provided with a magnetic ring 14. The magnetic ring can absorb the metal strip and can keep the correct track position to the greatest extent for movement.
[0042] Embodiment 2, as Figure 6 As shown, the storage tray 2 is made of glass, has an oblong shape, has arc-shaped sides, a square structure in the middle, a length of 80 cm to 140 cm, and a width of 50 cm to 80 cm. It is not only clean and hygienic but also relatively transparent for easy observation.
[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
