[0042] Refer to Figure 8 , Figure 9 and Figure 10 As shown, on the side of the swivel ring 3 for a microwave oven, a connecting shaft 5 is designed. A slit opening is provided on the connecting shaft 5, enabling the upper and lower halves of the connecting shaft 5 to deform inward. Cooperating with the guiding part at the front end of the through opening on the wheel 6, it makes it easier for the wheel 6 to be installed on the connecting shaft 5. The end of the connecting shaft 5 has a bulging part. After the wheel 6 is installed on the connecting shaft 5, the wheel 6 is not easily pulled out from the connecting shaft 5.

[0043] Refer to Figures 1-7 As shown, an automatic wheel sleeving device for the swivel ring of a microwave oven provided by the present utility model is used to install the wheel 6 on the connecting shaft 5 on the side of the swivel ring 3. Specifically, an automatic wheel sleeving device for the swivel ring of a microwave oven includes: a step disk 1, three sets of installation structures for the wheel 6, and a driving structure.

[0044] On the outer side of the top of the step disk 1, an annular opening 2 matching the inner ring of the swivel ring 3 is provided. The swivel ring 3 can be sleeved at the position of the annular opening 2 to stabilize the swivel ring 3. On the step disk 1 and equidistantly arranged along the circumference of the step disk 1 are three sets of installation structures for the wheel 6, that is, the three sets of installation structures for the wheel 6 are distributed in an annular array.

[0045] Specifically, according to the number of wheels 6 designed on the swivel ring 3 for a microwave oven, installation structures for different numbers of wheels 6 can be correspondingly designed to complete the installation of all the wheels 6 on the swivel ring 3 at one time.

[0046] The installation structure of the wheel 6 specifically includes: an arc-shaped opening 8 opened at the annular opening 2, a sliding support plate 10, and a guide groove 14.

[0047] The bottom side of the arc-shaped opening 8 penetrates through the annular opening 2 to form a first sliding track along the radial direction of the stepped disk 1. The sliding support plate 10 is slidably installed along the radial direction of the stepped disk 1 with respect to the stepped disk 1. And a rubber plate 12 is fixedly connected to the top of the sliding support plate 10 and located inside the first sliding track. A first push plate 11 parallel to the rubber plate 12 is fixedly connected to the end of the sliding support plate 10. The guiding groove 14 is fixedly arranged with the stepped disk 1. The guiding groove 14 and the stepped disk 1 can be fixed together by a bracket, or both can be fixed to the ground. The end of the guiding groove 14 corresponds to the arc-shaped opening 8, and the end of the guiding groove 14 corresponds to the rubber plate 12 and the first push plate 11, so that the wheel 6 sliding out from the end of the guiding groove 14 can be directly opposite to the arc-shaped opening 8, and the wheel 6 sliding out from the end of the guiding groove 14 is located between the rubber plate 12 and the first push plate 11. The driving structure is used to synchronously drive the sliding of the sliding support plate 10 in the installation structure of the three groups of wheels 6.

[0048] An automatic wheel slewing device for a turntable used in a microwave oven is used in cooperation with a conventional vibrating bowl. The number of vibrating bowls is the same as the number of installation structures of the wheels 6. Specifically, one end of the guiding groove 14 is fixedly connected to the discharge end of the vibrating bowl. A certain number of wheels 6 are placed inside the vibrating bowl. The vibrating bowl operates to move the wheels 6 in a single row sequence and then enter the guiding groove 14, so as to realize the continuous feeding of the wheels 6 into the guiding groove 14.

[0049] When in specific use, the driving structure synchronously drives the sliding of the sliding support plate 10 of the installation structures of the three groups of wheels 6. The principle of the installation structure of one of the wheels 6 is specifically described below: As Figure 6 shown in the figure, after the user installs the turntable 3 in place, at this time, the lowermost wheel 6 in the guiding groove 14 slides into the space between the rubber plate 12 and the first push plate 11. Restricted by the rubber plate 12 and the first push plate 11, the wheel 6 will not tilt. At this time, the wheel 6 is in an upright state, and the end of the wheel 6 is directly opposite to the arc-shaped opening 8. The connecting shaft 5 corresponds to the through hole of the wheel 6. The driving structure drives the sliding support plate 10 to slide radially inward along the stepped disk 1, thereby driving the rubber plate 12 and the first push plate 11 to slide synchronously, driving the wheel 6 close to the connecting shaft 5, and installing the wheel 6 on the connecting shaft 5. Subsequently, the driving structure drives the sliding support plate 10 to return to its original position. At this time, the sliding support plate 10 pushes the rubber plate 12 and the first push plate 11 to return to their original positions. Since the rubber plate 12 is made of an elastic material, it can move past the bottom of the wheel 6 and then prepare for the installation of the wheel 6 on the next turntable 3. The user removes the installed turntable 3 and replaces it with the next turntable 3 without the wheel 6 installed. By repeating this process, the efficient installation of the wheel 6 and the turntable 3 can be achieved.

[0050] In one embodiment, the driving structure includes: a motor 20, a driving disk 18, and a transmission column 17.

[0051] The motor 20 is fixedly installed on the top of the stepped disk 1, and the output shaft of the motor 20 penetrates through the stepped disk 1. The driving disk 18 is located below the stepped disk 1, and the driving disk 18 is fixedly installed with the output end of the motor 20. A driving ring track 19 is provided at the end of the driving disk 18. A transmission column 17 is fixedly connected to the bottom of the sliding support plate 10 and inside the driving ring track 19. The driving ring track 19 has an inwardly concave section that is recessed towards the center.

[0052] The motor 20 drives the driving disk 18 to rotate, and the ring track 19 also rotates accordingly. Restricted by the contour of the ring track 19, the driving transmission column 17 slides along the radial direction of the stepped disk 1, thereby driving the sliding support plate 10 to slide along the radial direction of the stepped disk 1.

[0053] In one embodiment, a plurality of support plates 21 distributed in an annular array are fixedly connected to the bottom of the stepped disk 1 for elevating and supporting the stepped disk 1 to ensure the normal operation of the driving structure.

[0054] In one embodiment, a baffle portion 4 is fixedly connected to the end of the rotating ring 3. A positioning port 7 corresponding to the baffle portion 4 is opened on the inner side of the annular port 2. When the baffle portion 4 is inserted into the positioning port 7, the rotating ring 3 is in the correct installation position, and at this time, the connecting shaft 5 corresponds to the through port of the wheel 6.

[0055] In one embodiment, the first push plate 11 is annular, and the shape of the first push plate 11 is similar to the shape of the wheel 6, so as to be able to smoothly push the wheel 6. A tail tow 13 is fixedly connected to the tail end of the first push plate 11. The design of the tail tow 13 makes the tail tow 13 block at the end of the guiding groove 14 when the first push plate 11 moves inward, preventing the wheel 6 from sliding out.

[0056] In one embodiment, an end limiting member 9 is fixedly connected to the outside of the stepped disk 1 at a position corresponding to the end of the guiding groove 14. The limiting member 9 is used to block the wheel 6 from sliding out of the outside of the stepped disk 1 to ensure that the wheel 6 corresponds to the connecting shaft 5.

[0057] In one embodiment, a sliding hole 16 is opened on the side surface of the sliding support plate 10. A fixing block 15 is fixedly connected to the bottom of the stepped disk 1 and inside the sliding hole 16. The fixing block 15 is slidably connected to the sliding hole 16 to realize the sliding installation of the sliding support plate 10 and the stepped disk 1.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
