[0025] Reference Figure 1 As shown, the utility model provides a technical solution: a tightly fitting middle sleeve, comprising a middle sleeve body 1.
[0026] The following is a detailed description of its overall specific settings and functions.
[0027] In this embodiment: a middle frame 5 is fixedly installed on the upper surface of the middle sleeve body 1, a connecting ring 3 is fixedly installed on the upper end of the middle frame 5, an elastic pad 4 is fixedly connected to the inner side of the middle frame 5, and a plurality of soft bags 6 are evenly fixedly connected to the outer surface of the middle frame 5, and the soft bags 6 are made of silicone. The elastic pad 4 will fit tightly on the surface of the cosmetic bottle, thereby improving the tightness of the fit between the middle sleeve body 1 and the cosmetic bottle. A swivel 2 is rotatably connected between the middle sleeve body 1 and the connecting ring 3, and a plurality of protrusions 7 are evenly fixedly connected to the inner side of the swivel 2, and the cross section of the protrusion 7 is triangular. In the process of rotating the swivel 2, the inclined surface of the protrusion 7 on the inner side of the swivel 2 will squeeze the soft bag 6, and in the process of squeezing the soft bag 6, the elastic pad 4 will stretch. The side wall of the swivel 2 is evenly fixedly connected with a plurality of convex patterns 8. The convex patterns 8 on the swivel 2 increase the friction between the hand and the swivel 2, and facilitate the twisting work of the swivel 2.
[0028] Specifically, the side wall of the swivel 2 is fixedly connected with a connection frame 9, and the lower surface of the connection frame 9 is fixedly connected with an elastic frame 10. The elastic frame 10 is formed by splicing two spring pieces with isosceles trapezoidal cross sections. The lower surface of the elastic frame 10 is fixedly connected with an insert plate 11. The side wall of the middle sleeve body 1 is evenly provided with a plurality of card slots 15, and the size of the card slot 15 is adapted to the size of the insert plate 11. The elastic frame 10 will stretch, and the insert plate 11 on the elastic frame 10 will be inserted into the inner side of the card slot 15 on the middle sleeve body 1, thereby facilitating the fixing of the swivel 2 after twisting. A pull rope 12 is fixedly connected to the inner side of the elastic frame 10, and the end of the pull rope 12 away from the elastic frame 10 passes through the elastic frame 10 and is fixedly connected with a sphere 14. When the pull rope 12 is pulled, the pull rope 12 will drive the elastic frame 10 to be compressed. A support frame 13 is fixedly connected to the upper surface of the connection frame 9. After the plug board 11 is lifted, the pull rope 12 can be sleeved on the inner side of the support frame 13, and the ball 14 can be stuck on the upper side of the support frame 13, so that the lifted plug board 11 can be temporarily fixed.
[0029] Working principle: when it is necessary to improve the tightness of the fit between the middle sleeve body 1 and the cosmetic bottle, first pull the pull rope 12, the pull rope 12 will drive the elastic frame 10 to compress, and after the plug plate 11 is lifted, the pull rope 12 can be sleeved on the inner side of the support frame 13, and the ball 14 will be stuck on the upper side of the support frame 13. At this time, the lifted plug plate 11 can be temporarily fixed. At this time, the swivel 2 can be rotated between the swivel 2 and the middle sleeve body 1. The convex pattern 8 on the swivel 2 increases the friction between the hand and the swivel 2, which facilitates the twisting of the swivel 2. In the process of rotating the swivel 2, the inclined surface of the protrusion 7 on the inner side of the swivel 2 will squeeze the soft bag 6. During the squeezing process of the soft bag 6, the elastic pad 4 will stretch, and the elastic pad 4 will fit tightly against the surface of the cosmetic bottle, thereby improving the tightness of the fit between the centering sleeve body 1 and the cosmetic bottle. At this time, the sphere 14 located above the support frame 13 is slid out, and the elastic frame 10 will stretch. The plug plate 11 on the elastic frame 10 will be inserted into the inner side of the card groove 15 on the centering sleeve body 1, thereby facilitating the fixing of the swivel 2 after twisting. By setting the above structure, the sealing effect of filling between the centering sleeve body 1 and the cosmetic bottle is facilitated, and the tightness of the fit between the centering sleeve body 1 and the cosmetic bottle is improved to a certain extent.
