[0114] The upper end of the bottom plug body 3 is matched with the middle plug body 2 to form a ring shape, and a peripheral wall protrusion 306 is provided on the outer wall surface. The peripheral wall protrusion slides through the second sliding notch α210 provided on the middle plug body 2 and enters the receiving groove 212 upward. The upper end of the bottom plug body 3 is sleeved in the middle plug body 2, and the bottom plug body 3 is rotated to slide the peripheral wall protrusion to the side of the side wall opposite to the sliding notch 208;

[0115] The upper plug body 1 is annular, and is connected to an extended member at the lower end. An installation block 103 is provided on the outer wall of the extended member. The installation block 103 slides into the notch 208 and enters the receiving groove 212, so as to pull the upper plug body 1 upward, and the upper plug body 1 is annularly sleeved inside the middle plug body 2;

[0116] The installation block 103 slides into the receiving groove 212 through the notch 208 and is limited by the side wall of the receiving groove 212 and slides out;

[0117] The depth of the accommodating groove 212 is the same as the thickness of the mounting block 103 and the peripheral wall protrusion, the distance from the right side of the mounting block 103 to the left side of the peripheral wall protrusion is the same as the width of the accommodating groove 212, and the middle plug body 2 is installed with the upper plug body 1 and the bottom plug body 3 on the inner wall sleeve, and the mounting block 103 cooperates with the peripheral wall protrusion to limit each other in the accommodating groove 212, so that the bottom plug body 3 and the upper plug body 1 can be installed on the middle plug body 2 by sliding up and down relative to each other.

[0118] The upper plug body 1, the middle plug body 2 and the bottom plug body 3 are all annular. The upper end of the middle plug body 2 cooperates with the upper plug body 1, and the lower end of the middle plug body 2 cooperates with the bottom plug body 3. The middle plug body 2 is provided with a receiving groove 212 on the inner wall surface. The side of the receiving groove 212 is provided with a sliding notch 208. The side wall and the upper wall of the receiving groove 212 limit the sliding range of the installation block 103. The installation block 103 slides through the sliding notch 208 and enters the receiving groove 212; the bottom plug The body 3 is detachably mounted on the lower end of the middle plug body 2. The bottom plug body 3 cooperates with the middle plug body 2 to be annular, and a bottom plug body peripheral wall protrusion 306 is provided. The bottom plug body peripheral wall protrusion 306 slides through the second sliding notch 210 provided on the middle plug body 2 to enter the receiving groove 212. The installation block 103 cooperates with the bottom plug body peripheral wall protrusion 306 to surround each other in the receiving groove 212. The bottom plug body 3 and the upper plug body 1 are installed on the middle plug body 2 by sliding up and down.

[0119] In the present invention, when installing the upper plug body, the middle plug body and the bottom plug body, fix the middle plug body 2 with one hand, rotate the bottom plug body 3 clockwise until it cannot rotate anymore, and then stop. When rotating the bottom plug body 3 clockwise, the part of the bottom plug body 3 that is connected to the lever 4 rotates to just above the lever 4 to ensure that the subsequent pins and levers can be installed in place.

[0120] The accommodating groove 212 provided on the middle plug body 2 is provided with a peripheral wall to cooperate with and control the rotation angle of the outer peripheral wall protrusion 306 .

[0121] The installation block 103 slides into the receiving groove 212, and the sliding notch 208 is set in the middle position of the side wall of the receiving groove 212. When the container plug is opened and sealed, the installation block 103 stays at the upper and lower ends of the receiving groove 212 respectively, and the upper plug body and the bottom plug body of the container plug move up and down. At this time, the installation block 103 will not slide out of the sliding notch 208. When disassembling, fix the middle plug body 2 with one hand, and exert force on the upper plug body 1 that interacts with each other up and down at the same time, and rotate the upper plug body 1 counterclockwise. When the installation block 103 slides to the exit position of the sliding notch 208, exert force to rotate the upper plug body 1 counterclockwise, and the installation block 103 slides out of the sliding notch 208, and then pull the upper plug body 1 upward to remove the upper plug body 1 from the middle plug body 2.

[0122] The outer wall protrusion 306 is matched with the second sliding notch 210 of the receiving groove 212. The second sliding notch 210 is set at the lower end of the up-and-down sliding position of the installation block 103. When the installation block 103 slides in the receiving groove 212, the outer wall protrusion 306 is blocked by it and cannot slide out of the receiving groove 212 through the second sliding notch 210, and is then limited to slide up and down in the receiving groove 212. When removing the bottom plug body, the upper plug body must be removed first. When the upper plug body 1 rotates counterclockwise, the bottom plug body 3 is driven to rotate counterclockwise. At this time, the outer wall protrusion 306 is just aligned with the second sliding notch 210, and the bottom plug body 3 is pulled downward. The outer wall protrusion 306 slides out of the second sliding notch 210, so that the bottom plug body 3 can be removed from the middle plug body 2.

[0123] In the present invention, the sliding block is pushed out by the inverted conical outer wall surface 206 , and the reciprocating motion of the sliding member within a limited range can prevent the elastic sealing sleeve 5 from being subjected to excessive extrusion force and causing wear, thereby improving the durability and sealing life of the elastic sealing sleeve 5 .

[0124] In the present invention, the installation of the sliding block on the bottom plug body is also completely detachable.

[0125] In the present invention, the sliding block 6 is distributed in a ring shape, and an elastic sealing sleeve is arranged on the periphery of its circumferential part, and its circumferential part fits the shape of the inner wall of the container mouth in the direction toward the container outlet, and an extrusion-type hard seal is formed when the circumferential part of the sliding block 6 presses the inner wall surface of the container mouth in the direction toward the container outlet.

[0126] The circumferential portion of the sliding block 6 is a plane in the direction toward the container outlet, and the inner wall of the container mouth is in contact with the plane of the circumferential portion of the sliding block 6 in the direction toward the container mouth to form a surface-to-surface seal;

[0127] The circumferential portion of the sliding block 6 is at a right angle, and the inner wall of the container mouth is provided with a step support surface to fit the plane of the circumferential portion of the sliding block 6 toward the container mouth during extrusion.

[0128] The circumferential portion of the sliding block 6 in the present invention is at a right angle, and is tightly connected to the step support surface at a horizontal plane at a right angle toward the container outlet, pressing the elastic sealing sleeve. The circumferential portion of the sliding block 6 is pressed and positioned in cooperation with the right-angled vertical surface, and is combined with the horizontal portion to form a stable sealing performance.

[0129] The sliding block 6 includes a plurality of displacement slider assemblies, each of which is distributed in a ring shape around the inverted conical outer wall of the middle plug body. The outer peripheral size of each displacement slider assembly pushed out by the inverted conical outer wall of the middle plug body 2 is larger than the minimum inner diameter of the container mouth, forming an inverted structure with the container mouth to lock the plug body with the container mouth, or the gap with the inner wall of the container mouth is smaller than the thickness of the elastic sealing sleeve to maintain close contact to achieve sealing and plugging.

[0130] The displacement slider assembly includes an inner displacement slider assembly and an outer displacement slider assembly. The inner sides of the inner displacement slider assembly 61 and the outer displacement slider assembly 62 are inserted in the guide groove. The guide groove of the inner displacement slider assembly 61 is deeper than the guide groove of the outer displacement slider assembly 62. The inverted cone angle from the guide groove corresponding to the inner displacement slider assembly to the inverted cone outer wall surface is larger than the inverted cone angle corresponding to the outer displacement slider assembly. The inner displacement slider assembly is arranged on the radial inner side of the outer displacement slider assembly to reduce the area occupied by the sliding block when it is not sealed. After being pushed out, the inner displacement slider assembly is pushed out faster than the outer displacement slider assembly, and when pushed to the outermost side, it forms a complete circular outer wall surface with the outer displacement slider assembly. The interval arrangement of the inner displacement slider assembly and the outer displacement slider assembly, and the partition 310 realize that each sliding block has a fixed motion trajectory when being pushed out or retracted, so that the outer wall surface of the inner displacement slider assembly and the outer wall surface of the inner displacement slider assembly form a preset shape when being pushed out, or only occupy a preset space when being retracted. The side walls of the inner displacement slider assembly and the side walls of the outer displacement slider assembly cooperate with each other to contact and slide out, and the outer wall surface of the inner displacement slider assembly is spliced ​​with the outer wall surface of the inner displacement slider assembly to form a shape that fits the inner wall of the container mouth.

[0131] The inner wall of the container mouth is circular. After the inner displacement slider assembly and the outer displacement slider assembly are pushed out by the middle plug body, they are combined at the outer periphery to form a circular outer peripheral wall to match the inner wall of the container mouth.

[0132] In the present invention, an annular mounting cavity 307 is provided on the bottom plug body 3, and the annular mounting cavity 307 is used to slide and install the sliding block 6 in the radial direction. The inner wall of the annular mounting cavity 307 of the sliding block 6 is hollow, and the hollow inner wall reserves space for placing the guide groove 213 of the middle plug body and the inverted cone outer wall surface 206 connected to the inner side thereof. When the sliding block 6 is not pushed out, it is radially movably placed in the annular mounting cavity 307, and its inner wall is opposite to the guide groove 213. The guide groove 213 limits the left and right movement of the sliding block, and it can only slide radially. An elastic sealing sleeve is sleeved on the outer periphery of its circumferential part. When the bottom plug body 3 is lifted by the lever 4, the bottom plug body simultaneously drives the sliding block 6 to move upward. The outer diameter of the inverted cone outer wall surface 206 increases as it goes upward, so the sliding block 6 will be pushed out, and then the sliding block 6 is pressed tightly against the elastic sealing sleeve 5 sleeved outside to seal the container mouth.

[0133] The annular mounting cavity 307 is evenly provided with partitions, and the inner displacement slider assembly and the outer displacement slider assembly are evenly distributed inside each partition. Each sliding block 6 can only slide in the radial direction along the bottom plug body 3 and cannot rotate in the axial direction of the bottom plug body 3.

[0134] The inverted conical outer wall surface 206 is evenly arranged on the side wall of the lower end of the middle plug body 2, and the inverted conical outer wall surface 206 is cooperatively arranged on the inner side of the guide groove 213, the guide groove of the inner displacement slider assembly is deeper than the guide groove of the outer displacement slider assembly, and the inverted conical outer wall surface corresponding to the inner displacement slider assembly has a larger angle than the inverted conical outer wall surface corresponding to the outer displacement slider assembly, so that the inner displacement slider assembly is arranged on the radial inner side of the outer displacement slider assembly, and the guide groove widths of each inner displacement slider assembly are the same, and the guide groove widths of each outer displacement slider assembly are the same, so as to avoid each sliding block 6 from sliding toward the two sides of the inverted conical outer wall surface 206, and realize that each sliding block 6 only slides in the longitudinal direction of the inverted conical outer wall surface.

[0135] The inverted conical outer wall surface 206 is arranged on the side wall of the lower end of the middle plug body, and the inverted conical outer wall surface is cooperatively arranged on the inner side of the guide groove. In the present invention, the guide groove 213 has another function, which is to prevent the middle plug body and the bottom plug body from being disassembled by mistake. When the sliding block 6 is inserted into the guide groove 213, the middle plug body and the bottom plug body cannot be rotated and disassembled with each other. Therefore, when disassembling, the sliding block 6 needs to be taken out from the annular mounting cavity 307 first, and the middle plug body and the bottom plug body can be rotated with each other. In this way, the action of manually taking out the sliding block 6 can avoid the misoperation caused by the misrotation between the middle plug body 2 and the bottom plug body 3. In the present invention, due to the design of the guide groove 213, when disassembling, the sliding block 6 needs to be disassembled and taken out first, and the upper plug body 1 is rotated to separate from the middle plug body 2. Otherwise, the upper plug body 1 and the middle plug body 2 cannot rotate and cannot be separated from the receiving groove 212.

[0136] In the present invention, the sliding block 6 uses a displacement slider assembly, which is convenient for matching with the inner wall of the container mouth of different shapes, and is also convenient for installation, and is convenient for expanding the tightening range of the outer wall surface. At the same time, the displacement slider assembly 6 uses the structure of the inner displacement slider assembly 61 and the outer displacement slider assembly 62, which reduces the space occupied by the displacement slider assembly when no sealing and plugging is required. The inner displacement slider assembly and the outer displacement slider assembly are also used to match different inverted cone-shaped outer wall surfaces to achieve a process in which the same component of the bottom plug body 3 moves in the direction of the outlet of the container mouth. Different displacement sliders are at different positions, achieving different sliding speeds, and reaching the appropriate position at the same time, so that the sliding block 6 can squeeze and seal the container sealing sleeve 5 with the inner wall of the container mouth at all parts in the direction toward the container mouth, forming a complete sealing ring, and at the same time, it can press the container sealing sleeve 5 upward and outward to ensure the stability of the sealing effect.

[0137] In the present invention, after the upper plug body 1 and the bottom plug body 3 are installed into the middle plug body 2, the inner displacement slider assembly 61 is first installed into the annular mounting cavity 307, and then the outer displacement slider assembly 62 is installed into the annular mounting cavity 307, and then the elastic sealing sleeve 5 is mounted on the outer wall of the bottom plug body 3.

[0138] In the present invention, after the upper plug body 1 and the bottom plug body 3 are installed on the middle plug body 2, the lower guide groove 213 of the middle plug body 2 is aligned with the annular installation cavity 307 of the bottom plug body.

[0139] In the present invention, after the sliding block 6 is installed, one end of the sliding block 6 is slid into and installed in the guiding groove of the middle plug body 2, and the other end of the sliding block 6 is movably installed in the annular installation cavity 307 of the bottom plug body 3. One end of the sliding block 6 cannot rotate circumferentially with the guiding groove of the middle plug body 2, and the other end of the sliding block 6 cannot rotate circumferentially with the bottom plug body 3. Therefore, after the sliding block 6 is installed, the middle plug body 2 and the bottom plug body 3 are locked and cannot rotate circumferentially. After the installation is completed, the upper plug body 1 and the bottom plug body 3 can only slide axially up and down with each other. Therefore, after the sliding block 6 is installed, the bottom plug body 3 and the middle plug body are locked. 2 and the upper plug body 1 can only slide axially up and down, and cannot rotate axially. When the upper plug body 1 is removed without the sliding block 6, the upper plug body 1 and the middle plug body 2 cannot rotate axially, and the upper plug body mounting block 103 cannot slide out of the middle plug body receiving groove 212. Therefore, when removing the upper plug body 1, the sliding block 6 must be removed first, so that when the container plug slides up and down during use, the upper plug body 1 will not be rotated due to accidental operation, causing the upper plug body 1 mounting block 103 to slide out of the middle plug body receiving groove 212 and the spring pin 8, resulting in the upper plug body 1 and the middle plug body 2 being disassembled due to accidental operation.

[0140] In the present invention, a lever 4 is selected as a transmission member connecting the upper plug body and the bottom plug body. When the upper plug body 1 is pressed down, the lever principle is utilized to accurately push the bottom plug body 3 upward. At the same time, the principle of the force transmitted by the lever is also utilized to easily push the bottom plug body 3 upward. The inverted conical outer wall surface provided at the lower end of the middle plug body 2 is utilized to realize the outward expansion of the bottom plug body 3 and the upward movement to compress the elastic sealing sleeve 5.

[0141] In the present invention, the lever 4 is also installed on the middle plug body 2 in a completely disassembled manner.

[0142] The upper opening of the middle plug body 2 is provided with a pin 17, and the lever 4 pivots and swings with the pin 17 as a fulcrum.

[0143] The end of one side of the lever 4 is connected to the lower part of the upper plug extension member 106, which is used as a connection point for the upper plug to drive the lever to swing up and down. The upper end of one side of the lever is connected to the lower end of the convex connecting part in the bottom plug, which is used as a connection point for the lever to drive the bottom plug to slide up and down.

[0144] The levers 4 are coaxially arranged with the pin 17 as the axis, and the movable block 16 is movably engaged with the pin 17 and sleeved on the pin, and the movable block 16 is sandwiched between the two levers 4;

[0145] The bottom of the middle plug body 2 is provided with a pin seat 214, and the two ends of the pin 17 are clamped in the clamping grooves at the two ends of the pin seat 214; the bottom plug body is provided with a second wall groove 309 for inserting the pin seat 214 at a matching position, and a space for the pin seat 214 to rotate is reserved on the second wall groove 309. After rotation, the part of the bottom plug body 3 supported on the lever 4 is vertical to the pin seat 214. When rotating, the pin seat 214 contacts the side wall of the second wall groove 309 to control the rotation angle, which is convenient for the installation of the lever 4 on the one hand, and convenient for lifting the bottom plug body 3 through the lever 4 on the other hand;

[0146] In the present invention, the bottom plug body 3 is installed on the middle plug body 2, and after it is rotated into place, the pin 17, the lever 4 and the sliding block are installed. First, the movable block 16 is sleeved on the pin 17, and then a lever 4 is respectively inserted from both ends of the pin 17 to form an assembly. This assembly can also be assembled in advance for standby; then the two ends of the pin 17 are placed in the slots set at both ends of the pin seat 214, and one end of the lever 4 is first placed on the lower end of the bottom plug body 3, and then the other end of the lever 4 is pressed down so that the two levers remain horizontal and parallel; the middle plug body 2 is fixed, and the bottom plug body 3 is rotated counterclockwise until it cannot be rotated. After the rotation, one end of the lever 4 is overlapped at the lower end of the overlapped part of the bottom plug body 3, and the other end of the lever 4 is also overlapped at the lower end of the overlapped part of the upper plug body 1. In the present invention, the lever 4 is sunken installed on the middle plug body 2, and the lever 4 is fixed to a position of the middle plug body 2 by the pin 17 and the sunken installation, and will not slide axially along the pin 17.

[0147] After installing the pin 1 and the lever 4, fix the middle plug body 2 with one hand, and then rotate the bottom plug body 3 counterclockwise until it cannot rotate. The outer wall protrusion 306 contacts the side wall of the accommodating groove 212 to control the rotation angle, or the pin seat 214 contacts the side wall of the wall groove 309 to control the rotation angle. After rotation, one end of the lever 4 is completely overlapped with the lower end of the overlapping part of the bottom plug body, and the other end is partially overlapped with the lower end of the overlapping part of the bottom plug body.

[0148] After the bottom plug body 3 is rotated counterclockwise, the components of the bottom plug body 3 and the corresponding parts of the upper plug body 1 can be accurately aligned when the upper plug body 1 is subsequently installed, and the installation block 103 can slide into the receiving groove 212 by sliding into the notch 208.

[0149] When installing the upper plug body 1, the upper plug body extension member 106 can be overlapped on the top of one end of the lever to ensure that the upper plug body can be rotated clockwise later, and after rotation, one end of the lever 4 is overlapped and aligned with the bottom of the upper plug body extension member 106, and the other end of the lever 4 is overlapped and aligned with the bottom of the bottom plug body overlap part.

[0150] In the present invention, the middle plug body 2 is pivotally connected to the lever 4 and serves as a fulcrum of the lever 4; one end of the lever 4 is arranged at the lower end of the upper plug body 1, and the upper part of the other end overlaps the bottom plug body 3, and the bottom of the bottom plug body 3 is provided with a slider guide cavity to guide the circumferential part of the sliding block 6 to push toward the inner wall of the container mouth; the bottom plug body 3 is arranged on the circumferential side of the middle plug body 2, and the middle plug body 2 is provided with an inverted tapered outer wall surface facing the bottom plug body 3;

[0151] The upper plug body 1 is pressed down, and the upper plug body 1 presses down one end of the lever 4, and the other end of the lever 4 lifts up the bottom plug body 3. When the bottom plug body 3 moves upward by the lever force, it lifts the sliding block 6, and the upward moving sliding block 6 is gradually pushed outward by the inverted cone-shaped outer wall of the middle plug body 2 until the elastic sealing sleeve 4 is squeezed to form a hard seal with the inner wall of the container.

[0152] The outer wall of the middle plug body is provided with a 7-shaped step 215, which is used to press against the container opening when the sealing plug is inserted into the container.

[0153] The 7-shaped step is provided with: the elastic ring 204 and the container are sealed, and the elastic force of the elastic ring is used to enhance the sealing effect. In the present invention, the middle plug body 2 is a plug body seat, the upper end is slidably connected to the upper plug body 1, and the lower end is slidable to the bottom plug body 3 through the inverted cone outer wall to expand outward and upward. By pressing down the upper plug body 1, the bottom plug body 3 is expanded outward and moved upward, and the elastic sealing sleeve 5 is squeezed and sealed between the bottom plug body 3 and the inner wall of the container mouth; by releasing the clamping of the upper plug body 1 on the bottom plug body 3, the squeezing of the elastic sealing sleeve 5 between the bottom plug body 3 and the inner wall of the container mouth is released, and the sealing of the bottom plug body 3 on the inner wall of the container mouth is released. The structural design is ingenious, and no additional screws or other connecting parts are required for fixing.

[0177] The upper plug body 1, the middle plug body 2 and the bottom plug body 3 in the present invention are inserted into each other, and the upper plug body 1 is rotated to drive the bottom plug body 3 to rotate together. The peripheral wall protrusion 306 provided on the bottom plug body 3 contacts the side wall surface of the receiving groove 212 to control the rotation angle. At this time, the upper plug body 1 can be installed on the middle plug body 2 by sliding up and down, and the bottom plug body 3 can be installed on the middle plug body 2 by sliding up and down. At this time, in the receiving groove 212, the peripheral wall protrusion 306 and the installation block 103 are in the receiving groove 212, and cannot move left and right in the receiving groove 212, but can only slide up and down.

[0178] When the upper plug body 1 rotates, the outer wall protrusion 306 of the bottom plug body 3 slides into the receiving groove 212. At the same time, the part of the bottom plug body 3 that is connected to the end of the lever 4 rotates to the upper end of the end of the lever 4 in the vertical direction.

[0179] In the present invention, when sealing is required, the upper plug body 1 is pressed down, and the bottom plug body 3 is lifted up by the lever 4. The inner wall of the bottom plug body 3 passes through the inverted cone-shaped outer wall of the middle plug body 2 to realize the upward and peripheral movement of the bottom plug body 3. At this time, the locking and positioning of the upper plug body 1 and the bottom plug body 3 are realized by the card groove 301 provided on the bottom plug body 3 and the spring pin 8 provided on the upper plug body, so as to ensure that the seal is in place (and locked), avoid excessive extrusion of the elastic sealing sleeve 5, and effectively avoid the elastic sealing sleeve 5 without effective extrusion sealing, which is easy to operate, convenient one-step operation, and stable sealing.

[0180] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 to Figure 1 As shown in FIG. 5 , the present invention further provides a rotating lock ring 12 for the button, and the rotating lock ring 12 rotates and locks the button to prevent the button from being pressed by mistake.

[0181] The upper plug body 1 is arranged on the outer side of the upper end of the button 7, and the upper end of the upper plug body 1 is connected to the rotating lock ring 12, and the stop block ridge 122 is arranged on the rotating lock ring 12. The button 7 includes a pressing part 705, and the lower end of the pressing part is connected to the stop block 704. The rotating lock ring 12 is arranged on the surrounding side of the pressing part 705. Rotating the rotating lock ring 12 drives the stop block ridge 122 to move to the lower end of the stop block 704, and the stop block 704 cannot move downward, so that the button 7 cannot be pressed.

[0182] The stop block 704 includes a plurality of convex ribs distributed on the lower end surface of the outer wall of the pressing portion 705; the rotating locking ring 12 includes a stop block convex edge 122 and a locking ring groove 123, and the locking ring groove 123 is invertedly installed on the upper plug body 1 and distributed around the button 7. Rotating the locking ring groove 123 drives the stop block convex edge 122 to rotate and clamp the stop block 704 to lock the stop block 704.

[0183] The rotating lock ring 12 is installed on the upper end of the upper plug body 1, and a C-shaped slot 18 is arranged on the circumference of the upper end of the upper plug body 1. A V-shaped elastic ring 15, a guide rail 23, and a U-shaped slider 13 are arranged in the C-shaped slot 18. The C-shaped slot 18 is fixedly connected to one side of the V-shaped elastic ring 15, and the other side of the V-shaped elastic ring 15 is fixedly installed in the opening of the U-shaped slider 13, so that the U-shaped slider can rebound and reset after being pressed. The C-shaped slot 18 is segmented with a guide rail 23 from the inside to the opening direction, and the U-shaped slider 13 is slidably installed on the guide rail 23;

[0184] The outer wall of the U-shaped slider 13 is provided with a sliding protrusion 131, and the inner wall of the rotating lock ring 12 is provided with an annular mounting groove 126 for rotationally mounting on the sliding protrusion 131. A plurality of pushing inclined surfaces 124 are evenly arranged in the annular mounting groove 126. The rotating locking ring 12 is rotated to push the sliding protrusion 131 laterally by the pushing inclined surfaces 124, so that the U-shaped slider 13 slides along the guide rail 23 in the longitudinal direction, and the rotating lock ring 12 rotates in a graduated manner, so as to rotate the block convex edge 122 in a controlled manner, and at the same time, it can effectively avoid rotation misoperation.

[0185] The pushing inclined surface 124 includes an upslope section, a flat slope section and a downslope section. The two sides of the sliding protrusion 131 are matched with the upslope section and the downslope section of the pushing inclined surface 124 to set corresponding slopes, so that the pushing inclined surface 124 can smoothly rotate and push the U-shaped slider 13 to move inward. The U-shaped slider 13 is evenly distributed in a ring shape, and each sliding protrusion 131 is also evenly distributed in a ring shape, so as to calculate the rotation angle of the rotating lock ring 12 and clarify the rotation angle of the block convex edge 122.

[0186] The two sides of the sliding protrusion cooperate with the uphill section and the downhill section of the push slope to set a corresponding slope;

[0187] The shape of the annular mounting groove 126 fits the sliding protrusion 131. The rotating lock ring 12 drives the annular mounting groove 126 to push the U-shaped slider 13 to compress the V-shaped elastic ring 15 to cooperate with the resistance drop generated by the annular mounting groove 126 to achieve indexing rotation. The arc of rotation can be controlled by the spacing distance set by the annular mounting groove 126, and the U-shaped slider 13 rebounds and resets through the V-shaped elastic ring 15.

[0188] In the present invention, six U-shaped sliders 13 are provided, twelve push inclined surfaces 124 are provided, and the rotating lock ring 12 is rotated by two 30°. After two push inclined surfaces 124 are pushed up and down, the U-shaped slider 13 is pushed once.

[0189] In the present invention, six U-shaped sliders 13 are evenly arranged in a ring shape, and twelve pushing inclined surfaces 124 are evenly arranged in a ring shape. The U-shaped slider 13 is pushed once by rotating the rotating lock ring through the pushing inclined surfaces 124. Each time the rotating lock ring is pushed, it rotates 30°, so that the rotating lock ring 12 rotates 30° each time.

[0190] In the present invention, the stopper 704 is evenly distributed in a ring shape with 6 intervals of 60°, the rotary lock ring stopper convex edge 122 is evenly distributed in a ring shape with 6 intervals of 60°, the stopper convex edge 122 and the pushing inclined surface 124 and the button stopper 704 are arranged on the same angle line, at this time, when the stopper convex edge 122 is at the lower end position of the stopper 704, the button 7 is locked, and the rotary lock ring 12 is rotated once to drive the stopper convex edge 122 and the stopper 704 to form a cross dislocation, so as to release the lock of the button 7, and the rotary lock ring 12 is rotated in turn to lock and unlock the button 7.

[0191] The pushing inclined surface 124 on the rotating locking ring is provided with an inclined surface outlet 125 in the direction toward the opening. The inclined surface outlet 125 is arranged at the flat slope section arranged on the pushing inclined surface 124. When the rotating locking ring 12 is pulled upward, the inclined surface outlet 125 contacts the sliding protrusion 131 during sliding, resulting in a movement tendency deviating from the radial direction, pushing the U-shaped slider 13 to slide radially inward, so as to realize the removal of the rotating locking ring.

[0192] In the present invention, the flat slope section arranged on the push slope 124 is convenient for placing the sliding protrusion 131, and the size of the slope outlet 125 matches the sliding protrusion 131, so as to facilitate the rotation of the lock ring 12 to separate from the upper plug body, realize the manual disassembly and assembly of various parts, and facilitate cleaning and installation.

[0193] In the present invention, the opening of the locking ring groove 123 is an eight-shaped trumpet opening, which is convenient for installing the sliding protrusion 131.

[0194] In the present invention, a rotary lock ring is provided outside the push button for the container, and the rotary lock ring 12 is rotated to drive the stopper convex edge 122 to move to the lower end of the stopper 704, and the stopper 704 cannot move downward, driving the button 7 unable to be pressed, and the button is locked by rotating the rotary lock ring. The distributed rotation structure provided on the rotary lock ring and the upper plug body facilitates the control of the degree of the rotary lock ring to achieve the push lock of the button, and at the same time, facilitates manual disassembly and installation, and is convenient for cleaning and installation.

[0195] In the present invention, the container plug is composed of four major components, namely, an upper plug body 1, a middle plug body 2, a bottom plug body 3, and an elastic sealing sleeve 5. The major components are composed of individual small components and small components, and the small components are composed of individual small components. During assembly, the small components are assembled first, and then the large components are assembled, and then the major components are assembled together to complete the assembly of the entire container plug. Due to the limitation of the structure of each component, there are sequence requirements for the assembly of each small component. The assembly of single small components and small components onto the large component is also subject to the limitation of the structure and has sequence requirements. The assembly of major components also has sequence requirements. When assembling small components onto the large component due to the influence of the structure, the large component needs to be assembled with other large components before it can be assembled onto the large component. There are also some components whose assembly sequence is not limited by the structure, and the sequence is relatively loose. Therefore, the assembly process of the container plug must be operated in accordance with the corresponding prescribed procedures, and the disassembly process is also the same, and must also be operated in accordance with the corresponding prescribed procedures.

[0196] In the present invention, the upper plug body 1 includes a spring pin 8, a buckle cover 9, a button 7, a pin spring 703, a rotating lock ring 12, a plurality of U-shaped sliders 13, and a V-shaped elastic ring 15.

[0197] The middle plug body 2 is composed of a pin seat 214 , an elastic ring 204 , a pin, a movable block 16 , a pin 17 and two levers 4 .

Third, install the V-shaped elastic ring 15, stretch the V-shaped elastic ring 15 to put it into the C-shaped groove 18; fourth, install the U-shaped slider 13, and the U-shaped slider 13 is slidably installed on the guide rail 23; fifth, install the rotating lock ring 12, press down the rotating lock ring 12, enter the eight-shaped horn opening of the lock ring groove 123, and use the eight-shaped inclined surface to push the U-shaped slider 13 to slide radially until the rotating lock ring 12 is installed in place; sixth, install the pin spring 703, and clip one end of the pin spring 703 into the limiting position of the peripheral wall of the buckle cover 9; seventh, install the button 7, press down the button 7 and use the J-shaped structure at the lower end of the button 7 to penetrate and hook it on the upper plug body.

[0202] In the second step, the middle plug body is installed with the bottom plug body. In the first step, the elastic ring 204 is installed and stretched to fit into the step of the outer peripheral wall of the middle plug body. In the second step, the middle plug body 2 is fixed, the upper end of the bottom plug body 3 is inserted along the lower end of the middle plug body, and the outer peripheral wall protrusion 306 of the bottom plug body slides into the receiving groove 212 along the second sliding notch 210 of the middle plug body. After sliding in, the bottom plug body 3 is rotated clockwise until it cannot rotate.

[0203] The third step is to install the movable block 16, lever 4 and pin 17 onto the middle plug body 2; the first step is to complete the assembly of the pin 17, the movable block 16 and the lever 4. First, put the movable block 16 on the pin 17, and then insert a lever from both ends of the pin 17 to form an assembly. This assembly can also be assembled in advance for standby use. The second step is to put the two ends of the pin 17 into the slots at both ends of the pin seat 214, first place one end of the lever 4 on the lower end of the bottom plug body 3, and then press down the other end of the lever 4 so that the two levers remain horizontal and parallel; the third step is to fix the middle plug body 2, and rotate the bottom plug body 3 counterclockwise until it cannot rotate. After rotation, one end of the lever 4 is overlapped at the lower end of the overlapping part of the bottom plug body 3, and the other end of the lever 4 is also overlapped at the lower end of the overlapping part of the bottom plug body;

[0204] Step 4: Assemble the upper plug body 1, insert the lower end of the upper plug body 1 along the upper end of the middle plug body 2, align the upper plug body mounting block 103 with the sliding notch 208 along the middle plug body 2, fix the middle plug body 2 and rotate the upper plug body clockwise until it cannot rotate, and slide the upper plug body mounting block 103 into the receiving groove 212 along the sliding notch 208;

[0205] Step 5: Assemble the sliding block to the bottom plug body 3, fix the middle plug body 2 and pull the bottom plug body 3 downward until it cannot be pulled, first install the inner displacement slider assembly 61 in the matching position of the annular installation cavity 307, and then install the outer displacement slider assembly 62. One end of the sliding block 6 contacts the inverted cone outer wall surface installed at the lower end of the middle plug body 2, and the other end is slidably installed in the annular installation cavity 307.

[0206] The sixth step is to assemble the elastic sealing sleeve 5, stretch the elastic sealing sleeve and insert it upward along the bottom plug body, and use the elastic force to shrink the upper end of the elastic sealing sleeve and wrap it around and clamp it in the groove for installing the elastic sealing sleeve 5 set at the lower end of the middle plug body 2, the middle part of the elastic sealing sleeve is wrapped around and fixed on the sliding block 6, and the lower end of the elastic sealing sleeve is wrapped around and fixed on the threaded step set at the lower end of the bottom plug body 3.

[0207] Step 7: Install the bottom of the elastic sealing sleeve. First, complete the assembly of the base. First, put the spring of the spring plunger on the plug body, then pass the end of the plug body 1101 away from the plug head through the middle hole of the base 21, and then stretch the elastic sealing pad 22 to fix it on one end of the plug ring groove. The assembly of this component can be completed in the previous steps. Then screw the internal thread of the base 21 on the external thread of the bottom plug body 3, and press the lower end of the elastic sealing sleeve 5.

[0208] The above steps complete the manual assembly of all parts of the entire sealing plug.

[0209] The following is a more reasonable disassembly process

[0210] The first step is to disassemble the base, fix the bottom plug body 3 and rotate the base 21 until the base is separated from the bottom plug body 3, fix the base 21, push the elastic sealing gasket 22 of the spring plunger 11, and use the stretching of the elastic sealing gasket 22 to remove the elastic sealing gasket.

[0211] The second step is to disassemble the elastic sealing sleeve 5, fix the middle plug body 2, pull the elastic sealing sleeve 5 downward, and use the elasticity of the elastic sealing sleeve to stretch until the elastic sealing sleeve is separated from the middle plug body and the bottom plug body.

[0212] The third step is to disassemble the sliding block 6, disassemble the outer displacement slider assembly 62 in sequence, and then disassemble the inner displacement slider assembly 61 in sequence.

[0213] The fourth step is to remove the upper plug body 1, fix the middle plug body 2, slide the upper plug body 1 up and down, and simultaneously apply force to rotate the upper plug body 1 counterclockwise while sliding. During sliding, the upper plug body 1 installation block 103 slides into the notch 208 and out of the middle plug body accommodating groove 212, and then pull the upper plug body upward to achieve the removal of the upper plug body.

[0214] The fifth step is to remove the lever 4, the pin 17, and the movable block 16, fix the middle plug body 2, and rotate the bottom plug body 3 clockwise until it cannot rotate. At this time, one end of the lever 4 is aligned with the overlapping part of the bottom plug body, and then pull the bottom plug body 3 downward to make one end of the lever 4 tilt up, and then pull one end of the lever 4 upward to make the two ends of the pin 17 slide out of the slots at both ends of the pin seat 214, and then remove the lever and the movable block from the pin.

[0215] Step 6: Remove the bottom plug 3. Step 1: Fix the middle plug 2 and rotate the bottom plug 3 counterclockwise until it cannot rotate. Then pull the bottom plug downward. The outer peripheral wall of the bottom plug 306 slides out of the receiving groove 212 along the second sliding notch 210 of the middle plug to remove the bottom plug. Step 2: Remove the elastic sealing ring. Fix the middle plug and stretch the elastic ring downward.

[0216] Step 7, disassemble the upper plug assembly, step 1, disassemble button 7, bend the button J-shaped hook from the bottom of the upper plug, and then push upward to complete the disassembly of button 7, step 2, remove the pin spring 703 from the buckle cover 9, step 3, disassemble the buckle cover 9, bend the buckle cover J-shaped hook from the bottom of the upper plug, and then push upward to complete the disassembly of the buckle cover, step 4, remove the spring pin and spring pin spring from the installation groove, step 5, disassemble the rotating lock ring 12, fix the upper plug body and rotate the rotating lock ring, and use it upward while rotating The rotating locking ring is pulled by force, and the inclined surface outlet 125 on the rotating locking ring is aligned with the sliding protrusion on the U-shaped slider 13 during rotation. During pulling, the inclined surface outlet contacts the sliding protrusion and produces a movement tendency deviating from the radial direction, pushing the U-shaped slider to slide radially inward to realize the removal of the rotating locking ring. In step 6, the U-shaped slider is removed from the C-shaped groove of the upper plug body. In step 7, the V-shaped elastic ring is stretched to separate it from the upper plug body. This step can also be placed in the front and then disassembled after the disassembly of the middle plug body is completed.

[0218] Example 1

[0219] like Figures 1 to 8 As shown, a completely disassembled container sealing plug of the present invention includes an inner push-type one-button push-sealing structure for an elastic sealing sleeve, including an elastic sealing sleeve 5, an inner push-type push-out structure for the elastic sealing sleeve and a push-start device, wherein the inner push-type push-out structure for the elastic sealing sleeve is arranged on the inner side of the elastic sealing sleeve 5, slides radially outward and its outer end face also moves outward to push out the elastic sealing sleeve 5 until it is pressed against the inner wall of the portion to be sealed on the opposite side, and the inner wall of the portion to be sealed is sealed and blocked in the relative direction of the medium outlet direction, the inner push-type push-out structure for the elastic sealing sleeve is pressed against the inner wall of the portion to be sealed on the outer side of its push-out direction, and the push-start device starts the inner push-type push-out structure of the elastic sealing sleeve in one step to push out the elastic sealing sleeve for extrusion sealing.

[0220] The elastic sealing sleeve 5 in the present invention is pushed out from the inside through the elastic sealing sleeve inner push-out structure arranged on the inner side. The elastic sealing sleeve 5 is rigidly supported by the elastic sealing sleeve inner push-out structure, which can effectively ensure the sealing effect. The pushing starter device pushes the elastic sealing sleeve inner push-out structure in one step, and the elastic sealing sleeve inner push-out structure is used to push out and extrude the elastic sealing sleeve 5 quickly and in one step, which is convenient and quick.

[0221] At the same time, by using the inner push-out structure of the elastic sealing sleeve on the inner wall of the part to be sealed in the direction of the medium outlet, the inner wall of the part to be sealed is used to extrude the hard seal in the relative direction of the medium outlet, which has a pressure-resistant effect. Especially when sealing carbonated beverages, hot water and other fluids with higher pressures, the positive pressure can be used to further enhance the sealing effect to avoid the seal being broken.

[0222] The elastic sealing sleeve is pushed out in an inner push-out structure and includes a sliding block 6, a bottom plug body 3, and an inverted conical outer wall surface 206. The bottom plug body 3 is internally slidably connected to the inverted conical outer wall surface 206, and the inverted conical outer wall surface 206 is inverted conical toward the side wall of the bottom plug body 3;

[0223] The bottom plug body 3 is provided with a plurality of sliding grooves 304, in which sliding blocks 6 are placed, and the sliding blocks 6 are distributed in a ring shape, and an elastic sealing sleeve is arranged on the periphery of the circumferential part thereof. When the bottom plug body 3 is ascending, the sliding blocks 6 are pushed outward by the sliding guide blocks 206 to squeeze the elastic sealing sleeve; or when the sliding block guide blocks move downward, the sliding blocks are pushed outward by the sliding block guide blocks to squeeze the elastic sealing sleeve;

[0224] When the sliding block slides radially outward, its outer end surface also moves outward to press the inner wall of the opposite side of the part to be sealed. When the sliding block slides radially inward, it separates from the inner wall of the part to be sealed, and the sealing or releasing of the sealing can be achieved quickly in one step.

[0225] In the present invention, the reciprocating motion of the sliding block 6 can be realized in an operative manner, and the elastic sealing sleeve 5 can be prevented from being worn due to excessive extrusion force in design, thereby improving the durability and sealing life of the elastic sealing sleeve 5.

[0226] The sliding block 6 includes a plurality of displacement slider assemblies, each of which is distributed in a ring shape around the inverted conical outer wall of the sliding guide block 206. The radial gap between the outer periphery of each displacement slider assembly pushed out by the inverted conical outer wall of the sliding guide block 206 and the container to be sealed is smaller than the thickness of the elastic sealing sleeve so as to keep the elastic sealing sleeve in close contact with the outer periphery of the sliding block 6 or the elastic sealing sleeve in close contact with the inner wall of the container mouth to achieve sealing and blocking.

[0227] The outer peripheral dimension of the sliding block 6 pushed out by the inverted conical outer wall surface 206 of the sliding block guide block is larger than the minimum inner diameter dimension of the container opening in its outlet direction, and forms an inverted structure with the container opening to lock the plug body in the container opening.

[0228] The displacement slider assembly includes an inner displacement slider assembly 61 and an outer displacement slider assembly 62. The inner displacement slider assembly 61 is accommodated in the interval between the outer displacement slider assemblies 62. The outer peripheral walls of the inner displacement slider assembly 61 and the outer peripheral walls of the outer displacement slider assembly 62 form mutually matching inclined surfaces. The inverted conical outer wall uses different inclined surfaces to match the inner displacement slider assembly 61 and the outer displacement slider assembly 62. The inner displacement slider assembly 61 is pushed out faster than the outer displacement slider assembly until the outer periphery of the inner displacement slider assembly 61 and the outer periphery of the outer displacement slider assembly 62 form a shape that fits the inner wall of the container in the direction toward the container opening.

[0229] In the present invention, the inner wall of the part to be sealed is circular, and the outer periphery of the inner displacement slider assembly 61 and the outer displacement slider assembly 62 are combined to form a circular outer peripheral wall to match the inner wall of the part to be sealed. The outer end surface of the sliding block 6 moving outward toward the sliding block is a plane, and the inner wall of the part to be sealed is attached to the outer end surface of the sliding block 6 to form a face-to-face squeeze seal at the part to be sealed facing the opposite side.

[0230] The circumferential portion of the sliding block 6 is at a right angle, and the inner wall of the portion to be sealed is provided with a stepped support surface to fit the plane of the outer end surface of the circumferential portion of the sliding block 6 moving outward toward the sliding block during extrusion.

[0231] The circumferential portion of the sliding block 6 in the present invention is at a right angle, and a horizontal surface at a right angle in the direction of the upper end face of the sliding block moving outward is tightly connected to the step support surface, pressing the elastic sealing sleeve. The circumferential portion of the sliding block 6 is pressed and positioned in cooperation with the right-angled vertical surface, and combined with the horizontal portion to form a stable sealing performance.

[0232] The sliding block 6 is distributed in a ring shape, and an elastic sealing sleeve is arranged around its circumferential part, and its circumferential part fits the shape of the inner wall of the part to be sealed in the direction toward the container outlet, and an extrusion-type hard seal is formed when the circumferential part of the sliding block 6 presses against the inner wall surface of the part to be sealed in the relative direction toward the outward moving upper end surface of the sliding block.

[0233] In the present invention, the sliding block 6 uses a displacement slider assembly, which is convenient for matching the inner wall of the part to be sealed with different shapes, and is convenient for expanding the scope of application. At the same time, the displacement slider assembly 6 uses the structure of the inner displacement slider assembly 61 and the outer displacement slider assembly 62, which reduces the space occupied by the displacement slider assembly when no sealing is required. The inner displacement slider assembly and the outer displacement slider assembly are also used to match different inverted cone-shaped outer walls to achieve a same component of the bottom plug body 3 in the direction of the upper end face of the sliding block moving outward. Different displacement sliders are at different positions, achieving different sliding speeds, and reaching the appropriate position at the same time, so that the sliding block 6 is squeezed and sealed with the inner wall of the part to be sealed at all parts in the direction of the outer end face of the sliding block moving outward to form a complete sealing ring. At the same time, the upper end face of the sliding block moving outward is in the direction and outwards of the container sealing sleeve 5 to ensure the stability of the sealing effect, especially when the pressure change in the container is greater than the pressure of the container sealing part, it can ensure a better sealing effect.

[0234] The inner wall of the portion to be sealed is circular, and the outer periphery of the inner displacement slider assembly 61 and the outer displacement slider assembly 62 are combined to form a circular outer peripheral wall that matches the inner wall of the container.

[0235] The present invention utilizes a sliding block arranged inside the elastic sealing sleeve to rigidly push out the elastic sealing sleeve 5, thereby ensuring the airtightness of the elastic sealing sleeve and the sealing effect; while the sliding block slides radially outward, its outer end also moves outward to press the inner wall of the opposite side to be sealed. When the pressure of the medium to be sealed increases, its positive pressure can further enhance the sealing effect and durability, and avoid the situation where the pressure in the sealing cavity is greater than the pressure at the sealing part and the sealing structure is damaged. The structure of the present invention has broad application prospects in the field of sealing technology.

[0236] The push start device comprises an upper plug body 1 and a lever 4, wherein the upper plug body 1 is slidably mounted on the middle plug body 2, and the lever 4 is pivotally connected to a fixed frame with the middle plug body 2 as a fulcrum; one end of the lever 4 is arranged at the lower end of the upper plug body 1, and the upper part of the other end overlaps the bottom plug body 3, and a slider guide cavity is provided at the bottom of the bottom plug body 3 to guide the circumferential part of the sliding block 6 to be pushed toward the inner wall of the container mouth; the bottom plug body 3 is arranged on the peripheral side of the middle plug body 2, and the middle plug body 2 is provided with an inverted conical outer wall surface facing the bottom plug body 3;

[0237] The upper plug body 1 is pressed down, and the upper plug body 1 presses down one end of the lever 4, and the other end of the lever 4 lifts up the bottom plug body 3. When the bottom plug body 3 moves upward by the lever force, it lifts the sliding block 6, and the upward moving sliding block 6 is gradually pushed outward by the inverted conical outer wall surface of the sliding block guide block 207 of the middle plug body 2 until the elastic sealing sleeve 4 is squeezed to form a hard seal with the inner wall of the container.

[0238] In the present invention, the upper plug body 1 is mechanically pressed down by contact with the lever 4, and the lever 4 is directly contacted with the bottom plug body 3 to be mechanically lifted. The bottom plug body 3 directly lifts the sliding block 6, and the sliding block 6 is also mechanically pushed out through the inverted cone-shaped outer wall surface of the sliding guide block 206.

No additional screws or other fixing structures are required, which also reduces the use of installation fixing screws, etc., which is healthy, environmentally friendly and saves materials; through the cooperation of various components, the connection and fixation between the various components are achieved, and the structure is stable.

[0241] In the present invention, a lever 4 is selected. When the upper plug body 1 is pressed down, the bottom plug body 3 can be accurately pushed up by the lever principle. At the same time, the principle of the force transmitted by the lever is also used to easily push up the bottom plug body 3. The bottom plug body 3 is expanded outwards and moved upwards to press the elastic sealing sleeve 5 by using the inverted conical outer wall provided at the lower end of the middle plug body 2. The upward movement of the bottom plug body 3 drives the sliding block 6 to expand outwards and press the elastic sealing sleeve 5.

A spring pin 8 is provided on the upper plug body 1, and a clamping groove 301 is provided at a matching position of the bottom plug body 3. When the bottom plug body 3 moves upward, the spring pin 8 is clamped into the clamping groove 301 to lock the bottom plug body 3 and the upper plug body 1, so as to fix the sealing locking of the bottom plug body 3 to the part to be sealed;

[0245] A button 7 is provided, which is slidably mounted on the upper plug body 1. A pushing member 701 is provided at the lower end of the button 7.
