[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments of the specification. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] On the contrary, the present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention as defined by the claims. Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these details.

[0033] See also Figure 1-2 A plastic stool separator based on a slide rail rotating device includes a lower hand wheel 1, an upper hand wheel 2, an upper chassis 3, an upper center turntable 4, a lower center turntable 5, a telescopic rod 6 and a lower chassis 7; the upper hand wheel 2, the upper chassis 3, the upper center turntable 4 and a group of telescopic rods 6 constitute an upper separation component; the lower hand wheel 1, the lower chassis 7, the lower center turntable 5 and a group of telescopic rods 6 constitute a lower separation component.

[0034] Specifically, Figure 3 As shown, the telescopic rod 6 includes a telescopic rod body 6-1, and a moving column 6-2 is provided on the telescopic rod body 6-1.

[0035] Specifically, Figure 4 As shown, the upper chassis 3 includes an upper chassis body 3-4, on which a group of upper slideways 3-1 are arranged toward the center and arranged circumferentially, and the telescopic rod body 6-1 of the telescopic rod 6 is cooperatively arranged in the corresponding upper slideway 3-1; a through hole 3-3 is opened in the middle of the upper chassis (3).

[0036] like Figure 5-6 As shown, the upper center turntable 4 includes an upper center turntable body 4-7, on which a group of upper slide grooves 4-1, a hollow shaft 4-3 and an upper tenon connection structure are provided. The upper tenon connection structure is provided with an upper tenon connection contact surface 1 4-2 and an upper tenon connection contact surface 2 4-4.

[0037] like Figure 7 As shown, the upper hand wheel 2 includes an upper hand wheel body 2-1, on which an upper mortise connection structure is provided, and on which an upper mortise connection contact surface 1 2-2 and an upper mortise connection contact surface 2-3 are provided.

[0038] The telescopic rod body 6-1 is slidably arranged in the corresponding upper slide 3-1 on the upper center turntable 4, and the movable column 6-2 of the telescopic rod 6 is arranged in the corresponding upper slide groove 4-1. The hollow shaft 4-3 is arranged in the middle of one side of the upper center turntable 4, and it is arranged along the through hole 3-3 to penetrate the upper chassis 3, and an upper tenon connection structure is opened at the end of the penetration end.

[0039] The telescopic rod 6 pushes the movable column 6-2 to slide in the upper slide groove 4-1 through the rotation of the upper center turntable 4, thereby realizing the horizontal sliding of the telescopic rod 6 in the upper slideway 3-1. The hollow shaft 4-3 passes through the through hole 3-3, so that the contact surface 3-2 on the upper chassis 3 contacts the upper surface 4-6 of the upper center turntable 4 for axial fixation.

[0040] The moving column 6-2 of the telescopic rod 6 slides linearly in the upper slide groove 4-1 to achieve telescopic movement, and the upper mortise connection contact surface 1 2-2 of the upper hand wheel 2 moves down along the tenon connection contact surface 1 4-2 until it is completely fitted, and then rotates counterclockwise so that the upper mortise connection contact surface 2-3 and the tenon connection contact surface 2 4-4 are completely fitted to achieve the relative fixation of the upper hand wheel 2 and the upper center turntable 4. The hollow shaft 4-3 is inserted into the solid shaft 5-2 of the lower center turntable 5 to adjust the position up and down. The hollow shaft 4-3 passes through the through hole 3-3 of the upper chassis 3 so that the contact surface 3-2 on the upper chassis 3 fits with the upper surface 4-6 of the upper center turntable 4 for axial fixation. Since the friction between the inner wall of the through hole 3-3 and the rolling bearing is small, the upper chassis 3 will not be driven to rotate when the upper center turntable 4 rotates.

[0041] Specifically, Figure 8-9 As shown, the lower chassis 7 includes a lower chassis body 7-4, on which a set of lower slides 7-1, a connecting shaft 7-2 and a lower chassis contact surface 7-3 are provided.

[0042] like Figure 10-12 As shown, the lower center turntable 5 includes a lower center turntable body 5-6, on which a group of lower sliding grooves 5-1, a solid shaft 5-2 and a lower mortise connection structure 5-3 at the upper end of the solid shaft 5-2, a mounting hole 5-4 and a lower contact surface 5-5 are provided.

[0043] like Fig.13 As shown, the lower hand wheel 1 comprises a lower hand wheel body 1-1, and a lower tenon connection structure 1-2 is provided on the lower hand wheel body 1-1;

[0044] The telescopic rod 6 pushes the movable column 6-2 to slide in the lower slide groove 5-1 through the rotation of the lower center turntable 5, and then the telescopic rod 6 can slide in the lower slide groove 7-1 to achieve telescoping. The lower chassis contact surface 7-3 contacts the lower contact surface 5-5 of the lower center turntable 5 for axial fixation, and the connecting shaft 7-2 cooperates with the mounting hole 5-4 on the lower center turntable 1 to fix the position of the chassis. A magnet 7-5 is provided at the top of the middle connecting shaft 7-2 of the lower chassis 7, and the axial connection between the lower chassis 7 and the lower center turntable 5 is achieved based on the magnetic attraction of the magnet 7-5. A rolling bearing is installed on the connecting shaft 7-2 to facilitate the relative rotation between the lower chassis 7 and the lower center turntable 5.

[0045] The movable column 6-2 of the telescopic rod 6 slides linearly in the lower slide groove 5-1 to achieve telescoping. The lower mortise connection structure 5-3 is connected to the lower tenon connection structure 1-2 of the lower hand wheel 1. The rotation direction of the lower center turntable 5 is controlled by rotating the lower hand wheel 2. When the bottom surface of the mounting hole 5-4 is connected to the connecting shaft 7-2 of the lower chassis 7, the magnet 7-5 is attracted to make the lower contact surface 5-5 of the lower center turntable 5 fit with the lower chassis contact surface 7-3 to achieve axial fixation. Since the friction between the side wall of the mounting hole 5-4 and the rolling bearing is relatively small, the lower center turntable 5 will not drive the lower chassis 7 to rotate when it rotates.

[0046] The lower tenon connection structure 1-2 is connected to the lower mortise connection structure 5-3 of the lower center turntable 5, so when the lower hand wheel 1 rotates, the lower center turntable 5 can be driven to rotate.

[0047] The assembly process of the separator in this embodiment is as follows:

[0048] When using the plastic stool separator to separate plastic stools, first slide the six telescopic rods 6 along the six slideways 7-1 of the lower chassis 7, adjust the position of the lower center turntable 5 so that the moving columns 6-1 of the six telescopic rods 6 are respectively located in the six slide grooves 5-1 of the lower center turntable 5, and then the magnets are attracted to achieve axial fixation. Then rotate the solid shaft 5-2 of the lower center turntable 5 to put the telescopic rods 6 in a retracted state. Place the upper chassis 3 on the front, slide the six telescopic rods 6 along the six slideways 3-1 of the upper chassis 3, then insert the hollow shaft 4-3 of the upper center turntable 4 into the through hole 3-3 of the upper chassis 3, adjust the position of the upper center turntable 4 so that the moving columns 6-1 of the six telescopic rods 6 are respectively located in the six slide grooves 4-1 of the upper center turntable 4, then rotate the hollow shaft 4-3 of the upper center turntable 4 to put the telescopic rods 6 in a retracted state. Turn over the connected upper center turntable 4, hold the hollow shaft 4-3 of the upper center turntable 4 and insert it into the solid shaft 5-2 of the lower center turntable 5 to make it slide down freely. Insert the hole of the upper hand wheel 2 through the hollow shaft 4-3 of the upper center turntable 4, so that the upper mortise connection contact surface 1 2-2 and the tenon connection contact surface 1 4-2 are completely fitted, then rotate the upper hand wheel 2 counterclockwise, so that the upper mortise connection contact surface 2-3 and the tenon connection contact surface 2 4-4 are completely fitted to achieve relative fixation, and then connect the lower tenon connection structure 1-2 of the lower hand wheel 1 with the lower tenon connection structure 5-3 of the lower center turntable 5 to achieve relative fixation.

[0049] The use process of the separator in this embodiment is as follows:

[0050] The plastic stool separator is to first place the lower chassis 7, the lower center turntable 5 and the telescopic rod 6 that cooperates with it, the upper center turntable 4 and the telescopic rod 6 that cooperates with it and the upper chassis 3 between two plastic stools through the center hole of the plastic stool, then hold the lower hand wheel 1 with one hand to make the bottom surface of the lower chassis 7 to the height of the upper stool surface of the second plastic stool, and rotate the lower hand wheel to make the telescopic rod 7 extend out enough to support the stool surface of the second plastic stool.

[0051] Then hold the upper hand wheel 2 with the other hand and rotate it counterclockwise to ensure that the upper hand wheel 2 is stuck with the upper center turntable 4, then lift it up until the upper chassis 3 is at the height of the lower surface of the first stool, and then rotate the upper hand wheel 2 to extend the telescopic rod 6 to resist the lower surface of the first plastic stool.

[0052] Finally, hold the upper hand wheel 2 and pull it upwards to achieve separation.

[0053] After the stool surface is separated, first remove the lower hand wheel 1. At this time, the lower chassis 7 and the lower center turntable 5 have been separated from the overall device. Then, lift the upper hand wheel 2 and place the first stool on the ground. Use one hand to support the upper center turntable 4 under the stool surface, and use the other hand to rotate clockwise to separate surface 6-3 from surface 4-4. The entire device can be dismantled.

[0054] The utility model is designed to solve the problem that it is difficult to separate tightly stacked plastic stools with both hands. The user can easily find the force application point and can separate the tightly stacked plastic stools without spending extra effort; the system is simple, easy to operate, and low in cost, which can greatly facilitate people's lives.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
