DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] This embodiment discloses a bottle cap, such as Figure 2 , 6As shown, it includes a cover body 200 and a sealing gasket 210. An internal thread that is compatible with the bottle mouth is formed on the inner circumference of the cover body 200, and the cover body 200 can be threadedly connected to the bottle mouth to achieve a connection between the cover body 200 and the bottle body; the sealing gasket 210 is installed on the inner end surface 201 of the cover body 200, and the sealing gasket 210 is embedded in the end surface. When the cover body 200 and the bottle mouth are installed, the sealing point and the end surface of the bottle mouth can be pressed against each other, thereby achieving a sealed connection.

[0032] An aluminum liner 211 is compositely bonded to the side of the sealing gasket 210 facing the inner end surface 201. The contour of the aluminum precipitate is consistent with the sealing gasket 210, and an extension edge 212 is formed on the periphery of the aluminum liner 211. The aluminum liner 211 is integrally connected with the extension edge 212, and the extension edge 212 is cylindrical and extends toward the opening 203. During installation, the sealing gasket 210 can be pressed into the cover body 200 through a press-fit device, and the extension edge 212 can be pressed outward, and the extension edge 212 is pressed and embedded in the inner peripheral surface of the cover body 200 to achieve fixation. The main body of the sealing gasket 210 is a PE foam sealing gasket 210.

[0033] In order to improve the connection stability of the sealing gasket 210, a limiting ring groove 202 can be opened on the inner circumferential surface of the cover body 200 near the inner end surface 201. The position of the limiting ring groove 202 is adapted to the position and height of the extension edge 212. When the outer peripheral part of the extension edge 212 is pressed, the outer periphery of the extension edge 212 can be deformed outward and embedded in the limiting ring groove 202. The sealing gasket 210 can be stably installed at the inner end surface 201 of the cover body 200 by mutually clamping the protruding extension edge 212 and the limiting ring groove 202.

[0034] This embodiment also discloses a bottle cap inner sealing gasket pressing device, such as Figure 1-6 As shown, the sealing gasket 210 of the bottle cap can be pressed by the pressing device, and then the extended edge 212 of the aluminum liner 211 can be pressed into the limiting ring groove 202, so that the aluminum liner 211 and the inner wall of the cover body 200 are mutually embedded and fixed.

[0035] The press-fitting device is adapted to the base 100 , and a receiving groove 101 is provided on the upper portion of the base 100 . The inner diameter of the receiving groove 101 is slightly larger than the outer circumference of the cover body 200 , and the cover body 200 can be placed into the receiving groove 101 , so that the cover body 200 can be kept stable during press-fitting.

[0036] The press-fitting device includes a press-fitting cylinder 1, a lifting seat 9 and a pressing rod. The press-fitting cylinder 1 is installed at the lower part of the lifting seat 9. The lifting seat 9 is driven to rise and fall by the pressing rod. Under the driving action of the pressing rod, the lifting seat 9 can be lifted, and then the bottle cap can be placed in the accommodating groove 101. The lifting seat 9 is pressed down by the pressing rod, and then the lower end of the press-fitting cylinder 1 is pressed into the cover body 200, and the sealing gasket 210 is stably pressed and fixed on the inner end surface 201 of the cover body 200.

[0037] like Figure 1-3 As shown, the outer peripheral contour of the press-fitting cylinder 1 is slightly smaller than the inner diameter of the bottle cap, and the press-fitting cylinder 1 can press the sealing gasket 210 into the inner end surface 201 of the cap body 200. The lower end of the press-fitting cylinder 1 has a flat cylinder bottom 2, which is flat and can press the sealing gasket 210 onto the inner end surface 201 of the cap body 200. After the sealing gasket 210 is pressed down, the press-fitting device can push the extended edge 212 on the outer periphery of the sealing gasket 210, and push the extended edge 212 to embed the extended edge 212 into the inner peripheral wall of the cap body 200, so as to achieve the embedded fixation between the sealing gasket 210 and the cap body 200.

[0038] like Figure 3 As shown, the press-fitting cylinder 1 is a hollow cylindrical structure, and a plurality of through grooves 3 are provided on the peripheral wall of the press-fitting cylinder 1. Each through groove 3 is an annular structure and is located near the cylinder bottom 2. A press-fitting block 4 is installed in the through groove 3, and the press-fitting block 4 is movably connected in the through groove 3 and can extend outward from the through groove 3, and the through groove 3 can be adjusted inward and outward.

[0039] When the press block 4 extends outward, the press block 4 can press the extended edge 212 into the limiting ring groove 202 on the inner circumferential surface of the cover body 200, so that the sealing gasket 210 and the cover body 200 are interlocked and fixed with each other; when the press block moves inward, the press block 4 can be retracted into the through groove 3. At this time, the press block 4 does not exceed the outer circumferential wall of the press cylinder 1, so that the press cylinder 1 can smoothly extend into the cover body 200, and the sealing gasket 210 is pressed and fixed flatly on the inner end surface 201 of the cover body 200.

[0040] A swing rod 5 is fixedly connected to one end of the press-fitting block 4 extending into the through slot 3, and an L-shaped structure is formed between the swing rod 5 and the press-fitting block 4. The upper end of the swing rod 5 is hinged to the inner cavity 22 of the press-fitting cylinder 1 through a hinge seat 6, and the swing rod 5 can swing along the radial direction of the press-fitting cylinder 1, so that the press-fitting block 4 at the lower end of the swing rod 5 can be telescopically adjusted in the through slot 3; by adjusting and pushing the swing rod 5, the press-fitting block 4 can be pushed outward, and the corresponding part of the extension edge 212 can be pressed into the limiting ring groove 202, so that the sealing gasket 210 and the cover body 200 are fixedly connected.

[0041] A spring 7 is elastically pressed between the swing rod 5 and the inner wall of the press-fitting cylinder 1, and the spring 7 can elastically push the swing rod 5 to swing inward, so that when the swing rod 5 swings inward, the press-fitting block 4 can be retracted. A recess is provided on the outward side of the swing rod 5, and the spring 7 can be embedded in the recess, so that the position of the spring 7 can be kept relatively stable.

[0042] like Figure 3 As shown, a rotating shaft 8 is installed in the middle of the inner cavity 22 of the press cylinder 1, the upper end of the rotating shaft 8 extends out of the press cylinder 1, and a bearing is installed on the upper side wall of the press cylinder 1, thereby realizing stable rotation support for the rotating shaft 8. A motor is installed on the upper part of the lifting seat 9, and the motor and the rotating shaft 8 are mutually connected in transmission, and the rotating shaft 8 can be driven to rotate by the motor. The motor can be a servo motor or a stepper motor, and the rotation control of the rotating shaft 8 can be realized.

[0043] A threaded section 11 is fixedly connected to the lower section of the rotating shaft 8 extending into the inner cavity 22. The outer diameter of the threaded section 11 is larger than that of the rotating shaft 8, and an external thread is provided on the outer periphery of the threaded section 11. An adjustment sleeve 12 is externally threadedly connected to the threaded section 11. The outer periphery of the adjustment sleeve 12 abuts against the swing rod 5, and is guided to slide up and down through the guide groove 501; a threaded screw structure is formed between the rotating shaft 8 and the adjustment sleeve 12. The rotating shaft 8 is driven to rotate by the motor, which can drive the adjustment sleeve 12 to rise and fall. During the process of rising and falling, the adjustment sleeve 12 can swing and adjust the corresponding swing rod 5.

[0044] An upper support tube 122 is fixedly connected to the upper part of the adjustment sleeve 12. An upper slideway 123 is provided on the outer periphery of the upper support tube 122. The upper slideway 123 is adapted to the position of the swing rod 5 and is arranged in a radial direction. An upper telescopic rod 13 is slidably connected in the upper slideway 123. The upper telescopic rod 13 can be telescopically adjusted in the upper slideway 123, thereby driving the upper telescopic rod 13 to push and adjust the swing rod 5.

[0045] When the upper telescopic rod 13 extends outward, the upper telescopic rod 13 can push the swing rod 5 outward to swing outward, and then the extended edge 212 of the aluminum liner 211 is pressed into the limiting ring groove 202 through the swing rod 5 and the press block 4. When the upper telescopic rod 13 is retracted inward, the telescopic rod can be retracted into the upper slide 123, and the swing rod 5 is swung inward under the action of the spring 7, so that the press block 4 at the lower end of the swing rod 5 is retracted, and the press cylinder 1 can be smoothly pressed into the cover body 200.

[0046] Furthermore, a limiting protrusion 124 is formed at one end of the upper slideway 123 facing outward, and a ball head 131 is fixedly connected to one end of the upper telescopic rod 13 facing inward, and a second spring 14 is elastically connected between the ball head 131 and the limiting protrusion 124. Under the connection and drive of the second spring 14, the upper telescopic rod 13 can be kept in a state of being retracted into the upper slideway 123. The ball head 131 extends inward from the upper slideway 123, and the ball head 131 and the upper limit sleeve 15 on the rotating shaft 8 are mutually pressed and adapted, and the ball head 131 can be pressed and pushed outward by the pressing drive, thereby ejecting the upper telescopic rod 13 outward.

[0047] Specifically, an upper limit sleeve 15 is installed on the rotating shaft 8 at the upper part of the threaded section 11. The lower end of the upper limit sleeve 15 is guided by a tapered surface 151, which is gradually reduced. The tapered surface 151 is adapted to the ball head 131 at the end of the upper telescopic rod 13. When the adjusting sleeve 12 is adjusted upward, the adjusting sleeve 12 and the upper limit sleeve 15 are moved closer to each other, and the upper limit sleeve 15 extends relatively into the upper support cylinder 122, and can push the upper telescopic rod 13 outward through the tapered surface 151 and the ball head 131. By rotating the adjusting rotating shaft 8, the adjusting sleeve 12 can be driven to move up and down, and the upper limit sleeve 15 and the upper telescopic rod 13 can be pressed and adapted to each other, thereby pushing the upper telescopic rod 13 outward, pushing the swing rod 5, and driving the press-fitting block 4 at the lower end to achieve the embedded press-fitting of the extended edge 212 of the aluminum precipitate.

[0048] Furthermore, the outer diameter of the threaded section 11 is larger than the shaft 8, and a stepped surface is formed at the upper end of the threaded section 11. The upper limit sleeve 15 is sleeved on the shaft 8, and the pressing and limiting is achieved through the stepped surface at the upper end of the threaded section 11. An annular recess is provided at the upper end of the upper limit sleeve 15, and a spring 3 16 is installed in the recess. The spring 3 16 elastically presses between the upper limit sleeve 15 and the upper side wall of the press-fitting cylinder 1, so that the upper limit sleeve 15 can be stably pressed onto the stepped surface.

[0049] When the adjusting sleeve 12 is adjusted upward, due to the greater hardness of the spring three 16, first, the ball head 131 on the upper telescopic rod 13 and the upper limit sleeve 15 press against each other, and the guide cone 151 pushes the guide, the upper telescopic rod 13 moves outward, and drives the swing rod 5; in the process of the upper telescopic rod 13 being pushed outward, it presses on the guide groove 501 on the inner side of the swing rod 5, thereby maintaining the stable lifting and sliding adjustment of the adjusting sleeve 12.

[0050] When the adjusting sleeve 12 rises to a certain position, the end face of the adjusting sleeve 12 and the upper limit sleeve 15 press against each other, and the upper telescopic rod 13 extends outward to the outermost end, and then the adjusting sleeve 12 rises further, which will overcome the spring three 16, and the adjusting sleeve 12 continues to move upward. The pressing position of the upper telescopic rod 13 and the swing rod 5 will continue to move upward, and will further drive the swing rod 5 to swing outward, thereby realizing the outward pressing and pushing of the press-fitting block 4, increasing the pressing strength and the extending length of the extended edge 212 of the aluminum liner 211, and further increasing the depth of the extended edge 212 pressed into the fiber ring groove, thereby improving the press-fitting stability between the sealing gasket 210 and the cover body 200.

[0051] Furthermore, a lower support tube 125 is fixedly connected to the lower position of the adjustment sleeve 12, and a plurality of lower slideways 126 are provided on the outer periphery of the lower support tube 125. The lower slideways 126 are adapted to the positions of the swing rod 5 in a one-to-one correspondence, and a lower telescopic rod 18 is slidably connected in the lower slideways 126, and the lower telescopic rod 18 can realize telescopic adjustment in the inner and outer directions in the lower slideways 126. Similar to the upper telescopic rod 13, when the lower telescopic rod 18 extends outward, it can push the swing rod 5 outward to swing outward, realize the outward ejection adjustment of the swing rod 5 and the press-fit block 4, and press-fit and fix the extended edge 212 of the aluminum liner 211; when the lower telescopic rod 18 can be retracted inward into the lower slideway 126, the lower telescopic rod 18 does not exert an outward pressure on the swing rod 5. The difference between the lower telescopic rod 18 and the upper telescopic rod 13 is that the upper telescopic rods 13 are pushed out synchronously, and the swing rods 5 and the press-fitting blocks 4 can be pushed out synchronously to press-fit the extended edge 212 of the aluminum liner 211; while the lower telescopic rods 18 are pushed out sequentially, and the swing rods 5 can be pushed out separately, and the extended edge 212 of the aluminum liner 211 can be partially press-fitted. Moreover, the lower telescopic rod 18 is located at the lower side, which is relatively more labor-saving, and the local single press-fitting effect is better, which is for early pre-pressing.

[0052] A vertical support plate 182 is fixedly connected to the inner end of the lower telescopic rod 18, and a horizontal support plate 181 is fixedly connected to the upper part of the vertical support plate 182. The horizontal support plate 181 extends in the direction of the rotating shaft 8, and is fixedly connected between the vertical support plate 182 and the horizontal support plate 181 to form an inverted L-shaped structure. The horizontal support plate 181 and the raised position on the adjustment sleeve 12 are pressed against each other to form a limit, thereby keeping the lower telescopic rod 18 in a relatively stable travel range. A spring four 19 is elastically connected between the vertical support plate 182 and the lower support tube 125, and the elastic support of the spring four 19 can keep the lower telescopic rod 18 in an inward telescopic state.

[0053] like Figure 3As shown, a lower limit sleeve 17 is fixedly connected to the lower end of the threaded section 11, and the bottom position of the lower limit sleeve 17 is fixedly connected to the rotating shaft 8 through a connecting plate 171, forming an annular support component structure between the lower limit sleeve 17. The upper end of the lower limit sleeve 17 extends upward, can extend into the inner side of the lower support tube 125, can abut against the inner side of the vertical support plate 182, and then limit the inward formation of the lower telescopic rod 18.

[0054] like Figure 5 As shown, a protrusion 172 is fixedly connected to the outer periphery of the lower limit sleeve 17, and the outer side of the protrusion 172 is in an arc transition. During the rotation of the rotating shaft 8, the protrusion 172 will follow the rotation process of the rotating shaft 8. When the adjustment sleeve 12 is lowered and adjusted to a certain amplitude, the lower limit sleeve 17 will extend into the inner position of the vertical support plate 182 of the adjustment sleeve 12. The position of the protrusion 172 on the outer periphery of the lower limit sleeve 17 can push out the vertical support plate 182 at the corresponding position. Since there is only one protrusion 172, during the rotation of the rotating shaft 8, the position of the protrusion 172 will be adjusted in the axial direction, and then the vertical support plate 182 can be pressed and pushed in turn, and the telescopic rod is pushed outward to push the swing rod 5 outward. From the state of single one-by-one ejection, the swing rod 5 can be pushed in turn, and then the extended edge 212 of the aluminum liner 211 can be pressed and embedded in the limit ring groove 202, so as to achieve the mutual fixation between the cover body 200 and the sealing gasket 210.

[0055] After the press-fitting cylinder 1 presses the sealing gasket 210 in, the motor first drives the rotating shaft 8 to rotate, adjusts and moves the adjusting sleeve 12 downward, and the rotating shaft 8 drives the lower limit sleeve 17, which in turn drives the swing rod 5 and the press-fitting block 4 to press outward, and locally presses and engages the extended edge 212 of the aluminum gasket 211. By pressing one by one, the aluminum gasket 211 and the limit ring groove 202 of the cover body 200 can be kept fixed, and the sealing gasket 210 and the cover body 200 are fixed. Then, the motor reverses and moves the adjustment sleeve 12 upward. The adjustment sleeve 12 and the upper limit sleeve 15 are pressed and adapted to each other, driving the swing rod 5 and the press-fitting block 4 to press outward. Each swing rod 5 and the press-fitting block 4 is pressed and stretched out toward the periphery at the same time, and the extended edge 212 of the aluminum liner 211 is partially pressed on the periphery and embedded into the limiting ring groove 202, so as to realize the connection between the extended edge 212 of the aluminum liner 211 and the cover body 200, and the sealing gasket 210 is stably pressed into the cover body 200, so as to maintain the stability of the sealing gasket 210.

[0056] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
