Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing can buckle technology, and in particular to an adjustable sealing can buckle structure. Background Technology
[0002] In everyday household storage, kitchen food storage, food processing, and laboratory sample storage, airtight containers, as storage containers with dustproof, moisture-proof, and oxidation-proof functions, are widely used to store grains, tea, nuts, seasonings, and small amounts of experimental samples. The snap-fit structure is the core component that enables the detachable connection between the lid and the container and the sealing function. Its adaptability and practicality directly affect the user experience of the airtight container.
[0003] Currently, most mainstream sealing can buckles on the market adopt a fixed-size design. The lower mounting part and the upper mounting part are fixed to specific structural dimensions by integral molding or welding. The arc diameter of the lower mounting part and the fitting dimensions between the upper mounting part and the groove of the lid are all predetermined, and can only be used with sealing can bodies and lids of corresponding specifications. This fixed-size buckle structure has significant limitations. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable sealing can buckle structure.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable sealing can buckle structure, comprising:
[0006] The bottle body has a bottle opening at its top, which serves as the mounting reference for the lower mounting part.
[0007] The lid has a plug fixedly connected to its lower surface and a groove provided on its upper surface, which serves as the assembly carrier for the upper mounting part.
[0008] The lower mounting part is fixedly installed along the outer peripheral wall of the bottle mouth, and its spatial position corresponds to the upper mounting part when the cap is closed.
[0009] The upper mounting part is fitted into the groove of the cover, and one end of the upper mounting part is rotatably engaged with the corresponding end of the lower mounting part to form a rotating connection structure that flips around a horizontal axis.
[0010] The pressing part is located on the side of the lower mounting part away from the rotating connection end, and the lower end of the pressing part is rotatably connected to the spring steel wire of the lower mounting part.
[0011] The hook locking part is rotatably connected to the pressing part in the middle, and the hook part of the hook locking part faces the upper mounting part;
[0012] The adjustment component is provided in two sets: one set is provided along the contact surface between the lower mounting part and the bottle mouth, and the other set is provided along the contact surface between the upper mounting part and the cap groove.
[0013] When the pressing part is pressed down, the pressing part flips downward around its rotational connection point with the lower mounting part, causing the hook locking part to rotate synchronously around the connection point of the two, so that the hook of the hook locking part hooks the upper mounting part. As the hook locking part hooks, the upper mounting part causes the cap to flip downward around its rotational connection point with the lower mounting part until the cap closes to the bottle mouth. At the same time, the stopper is inserted into the bottle mouth as the cap closes. The locking force between the lower mounting part and the bottle body, and between the upper mounting part and the cap can be adjusted separately by the adjusting component.
[0014] Preferably, the upper mounting part is integrally bent from spring steel wire, forming an arc-shaped structure that fits the inner wall of the cap groove. The center of this arc-shaped structure coincides with the central axis of the cap. The two ends of the spring steel wire are bent downwards towards the bottle opening to form two symmetrically arranged hooks. The openings of the hooks face the lower mounting part. The section of the arc-shaped structure away from the hooks protrudes outwards in a direction away from the inner wall of the cap groove to form a rectangular frame. The inner cavity size of the rectangular frame matches the hook size of the hook locking part, allowing the hook locking part to hook in. The hook is hooked on the outer periphery of the rotating arm of the lower mounting part, and the hook can rotate circumferentially around the axis of the rotating arm to achieve rotational engagement between the upper mounting part and the lower mounting part.
[0015] Preferably, the lower mounting part is integrally bent from a spring steel wire, forming an arc-shaped structure that fits the outer peripheral wall of the bottle mouth. The center of this arc-shaped structure coincides with the central axis of the bottle. Both ends of the spring steel wire are bent upwards towards the cap, and the two bent ends are fixedly connected to each other to form a closed-loop rotating arm. The outer peripheral surface of the rotating arm is in contact with the inner wall of the hook of the upper mounting part. When the cap is flipped, the hook can slide along the outer peripheral surface of the rotating arm, causing the upper mounting part and the lower mounting part to rotate relative to each other.
[0016] Preferably, the pressing part is a U-shaped structure formed by bending a spring steel wire. The opening of the U-shaped structure faces the outside of the bottle body, and both ends of the U-shaped structure are bent inward to form a bushing. The bushing is fitted around the outer periphery of the section of the spring steel wire of the lower mounting part away from the rotating arm, so that the pressing part can rotate around the axis of this section. The hook locking part is a rod-shaped structure with a hook at one end. A shaft hole is opened at the end away from the hook. A rotating shaft is fixedly connected between the two opposite inner sidewalls of the U-shaped structure of the pressing part. The shaft hole is fitted around the outer periphery of the rotating shaft, so that the hook locking part can rotate around the axis of the rotating shaft. When the free end of the pressing part is pressed down, the pressing part rotates downward around the axis of the bushing, driving the rotating shaft to move downward synchronously, so that the hook locking part rotates around the rotating shaft until the hook is hooked into the rectangular frame of the upper mounting part. When the free end of the pressing part is lifted up, the pressing part rotates in the opposite direction, driving the hook locking part to disengage from the rectangular frame. At this time, the cap can be flipped up to open.
[0017] Preferably, the two ends of the spring steel wire constituting the lower mounting part are free ends, and the two free ends are arranged opposite each other along the length direction of the spring steel wire. An adjustment sleeve is provided between the two free ends. The two ends of the adjustment sleeve are respectively sleeved on the outer periphery of the two free ends, and the adjustment sleeve can rotate relative to the free ends. When the adjustment sleeve is rotated, the two free ends can move towards or away from each other along the axial direction of the adjustment sleeve, changing the diameter of the arc-shaped structure of the lower mounting part to adapt to bottle mouths of different sizes.
[0018] Preferably, the inner cavity of the adjusting sleeve has two internal threads along the axial direction, and the two internal threads are located at the two ends of the adjusting sleeve respectively. The two internal threads have opposite directions of rotation. The outer circumference of the two free ends constituting the lower mounting part is machined with external threads. The direction of rotation of the external threads of the two free ends matches the direction of rotation of the internal threads of the corresponding ends of the adjusting sleeve. The external threads and internal threads mesh to form a threaded pair. When the adjusting sleeve is rotated clockwise, the two free ends move towards each other under the drive of the reverse threads, which reduces the arc diameter of the lower mounting part and enhances the clamping force with the bottle mouth. When the adjusting sleeve is rotated counterclockwise, the two free ends move away from each other, which increases the arc diameter and weakens the clamping force.
[0019] Preferably, the adjusting component includes a mounting plate, a base block, a fixing block, a locking rod, and a pull strap. The base block has a cuboid structure, with one side of it fitting against the side of the upper mounting part or the side of the lower mounting part. Two mounting plates are provided, respectively bonded to the upper and lower sides of the base block. The side of the mounting plate away from the base block is fixedly connected to the inner wall of the groove in the cap or the outer wall of the bottle opening. A guide groove is formed on the upper surface of the base block along its length, penetrating both ends of the base block. The width of the guide groove matches the width of the pull strap. One end of the pull strap is connected to one end of the base block. The end face is fixedly connected, and the other end passes through the conveyor belt groove and extends to the outer side of the other end of the base block. The middle part of the pull belt wraps around the outer periphery of the upper or lower mounting part. The fixing block is vertically fixed to the upper surface of the base block and is located above the conveyor belt groove. The locking rod is inserted along the radial thread of the fixing block, and the lower end of the locking rod can extend into the conveyor belt groove. Pulling the free end of the pull belt can adjust the length of the pull belt wrapping around the upper or lower mounting part. After adjusting to the preset locking force, tighten the locking rod so that the lower end of the locking rod abuts against the upper surface of the pull belt to fix the position of the pull belt.
[0020] Preferably, the rotating shaft is a cylindrical rod with its axis perpendicular to the opening direction of the U-shaped structure of the pressing part, and the two ends of the rotating shaft are welded and fixed to the two inner side walls of the U-shaped structure respectively. The inner wall of the shaft hole of the hook locking part is clearance-fitted with the outer peripheral wall of the rotating shaft, so that the hook locking part can rotate flexibly around the axis of the rotating shaft to avoid jamming.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this utility model, the coordinated design of the adjusting sleeve and the adjusting component effectively solves the problem that traditional buckles can only be used with sealed containers of fixed size. The adjusting sleeve of the lower mounting part adopts a reverse thread design, which can drive the free end of the spring steel wire to move towards or away from each other when rotated, flexibly changing the arc diameter of the lower mounting part, thereby adapting to bottle mouths of different diameters.

[0030] Example 1, such as Figure 1-6As shown, an adjustable sealing can buckle structure includes a bottle body 1, a cap 2, a lower mounting part 5, an upper mounting part 6, a pressing part 7, a hook locking part 9, and adjusting components. The top of the bottle body 1 has an annular opening, the outer wall of which is polished smooth to serve as the mounting reference for the lower mounting part 5. A stopper 4 made of elastic silicone material is bonded to the lower surface of the cap 2; the shape of the stopper 4 matches the inner cavity of the bottle body 1's opening. An annular groove 3 is formed on the upper surface of the cap 2; the inner wall of the groove 3 is polished to serve as the assembly carrier for the upper mounting part 6. The lower mounting part 5 is integrally bent from 65Mn spring steel wire, forming an arc-shaped structure that matches the outer wall of the bottle body 1's opening. It is fixed along the outer wall of the bottle body 1's opening by welding, and the spatial position of the lower mounting part 5 corresponds to the upper mounting part 6 when the cap 2 is closed. The upper mounting part 6 is also integrally bent from 65Mn spring steel wire, forming an arc-shaped structure that fits the inner wall of the groove 3 of the cap 2. The center of this arc-shaped structure coincides with the central axis of the cap 2. The upper mounting part 6 is embedded in the groove 3 of the cap 2. The two ends of its spring steel wire are bent downwards towards the bottle mouth of the bottle body 1 to form two symmetrically arranged hooks, with the hook openings facing the lower mounting part 5 below. The two ends of the spring steel wire of the lower mounting part 5 are bent upwards towards the cap 2, and the two bent ends are fixedly connected by welding to form a closed-loop rotating arm. The hooks of the upper mounting part 6 are hooked onto the outer periphery of the rotating arm of the lower mounting part 5. The inner side of the hook is smoothed, allowing it to rotate circumferentially around the axis of the rotating arm, realizing a rotating connection structure in which the upper mounting part 6 and the lower mounting part 5 can flip around the horizontal axis. The pressing part 7 is located on the side of the lower mounting part 5 away from the rotating connection end. It is made of 65Mn spring steel wire bent into a U-shape. The opening of the U-shape faces the outside of the bottle body 1, and both ends of the U-shape are bent inward and welded with bushings. The bushings are fitted around the outer periphery of the section of the spring steel wire of the lower mounting part 5 away from the rotating arm, allowing the pressing part 7 to rotate around the axis of this section. The hook locking part 9 is a rod-shaped structure with an arc hook at one end. A shaft hole is opened at the end away from the hook. A cylindrical rotating shaft 8 is welded and fixed between the two opposite inner sidewalls of the U-shaped structure of the pressing part 7. The axis of the rotating shaft 8 is perpendicular to the opening direction of the U-shaped structure of the pressing part 7. The shaft hole of the hook locking part 9 is fitted around the outer periphery of the rotating shaft 8. The inner wall of the shaft hole and the outer peripheral wall of the rotating shaft 8 are clearance-fitted, allowing the hook locking part 9 to rotate flexibly around the axis of the rotating shaft 8. The arc hook of the hook locking part 9 faces the upper mounting part 6. The arc-shaped structure of the upper mounting part 6, in the section away from the hook, protrudes outward along the direction opposite to the inner wall of the groove 3 of the cap 2 to form a rectangular frame. The inner cavity size of this rectangular frame is adapted to the size of the arc-shaped hook of the hook locking part 9, allowing the hook of the hook locking part 9 to engage. Two sets of adjustment components are provided: one set is arranged along the contact surface between the lower mounting part 5 and the bottle mouth of the bottle body 1, and the other set is arranged along the contact surface between the upper mounting part 6 and the groove 3 of the cap 2. The adjustment components include a mounting plate 11, a base block 12, a fixing block 13, a locking rod 14, and a pull strap 16.The base block 12 has a cuboid structure, with one side of it fitting against the side of the upper mounting part 6 or the side of the lower mounting part 5. Two mounting plates 11 are provided, respectively bonded to the upper and lower sides of the base block 12 with strong adhesive. The side of the mounting plate 11 away from the base block 12 is fixed to the inner wall of the groove 3 of the cap 2 or the outer wall of the bottle mouth of the bottle body 1 by adhesive. A conveyor belt groove 15 is formed along the length of the upper surface of the base block 12, penetrating both ends of the base block 12, and the width of the conveyor belt groove 15 is adapted to the width of the pull strap 16. The pull strap 16 is made of high-strength nylon, with one end fixed to one end face of the base block 12 by riveting, and the other end passing through the conveyor belt groove 15 and extending to the outer side of the other end of the base block 12. The middle of the pull strap 16 wraps around the outer periphery of the upper mounting part 6 or the lower mounting part 5. The fixing block 13 is vertically welded to the upper surface of the base block 12, and the fixing block 13 is located above the conveyor belt groove 15. The locking rod 14 is inserted along the radial thread of the fixing block 13, and the lower end of the locking rod 14 can extend into the conveyor belt groove 15. The two ends of the spring steel wire constituting the lower mounting part 5 are free ends, and the two free ends are arranged opposite to each other along the length direction of the spring steel wire. An adjusting sleeve 10 is provided between the two free ends, and the two ends of the adjusting sleeve 10 are respectively fitted onto the outer circumference of the two free ends. The inner cavity of the adjusting sleeve 10 has two sections of internal threads along the axial direction, and the two sections of internal threads are located at the two ends of the adjusting sleeve 10 and have opposite directions of rotation. The outer circumference of the two free ends constituting the lower mounting part 5 is machined with external threads, and the rotation direction of the external threads of the two free ends matches the rotation direction of the internal threads of the corresponding ends of the adjusting sleeve 10. The external threads and internal threads mesh to form a threaded pair.
[0031] Working principle: When it is necessary to close the cap 2 onto the bottle body 1, first place the cap 2 above the bottle mouth of the bottle body 1, so that the hook of the upper mounting part 6 hooks onto the rotating arm of the lower mounting part 5. At this time, the stopper 4 is facing the bottle mouth of the bottle body 1. Then, press down on the free end of the pressing part 7 with your finger. The pressing part 7 rotates around the bushing at its port on the spring steel wire of the lower mounting part 5, driving the rotating shaft 8 welded to the inner wall of the pressing part 7 to move downward in sync. The hook locking part 9 rotates around the axis of the rotating shaft 8, and its arc-shaped hook gradually approaches and finally hooks into the rectangular frame of the upper mounting part 6. With the continuous pressing of the pressing part 7, the upper mounting part 6, under the pulling force of the hook locking part 9, drives the cap 2 to rotate around the rotating arm of the lower mounting part 5 until the cap 2 is completely closed onto the bottle mouth of the bottle body 1. At this time, the stopper 4 is inserted into the bottle mouth of the bottle body 1 to achieve a seal. To adjust the clamping force between the lower mounting part 5 and the bottle opening 1, the adjusting sleeve 10 can be rotated. Since the internal threads at both ends of the adjusting sleeve 10 rotate in opposite directions, the two free ends of the lower mounting part 5 will move towards or away from each other under the action of the threads, thereby changing the diameter of the arc-shaped structure of the lower mounting part 5 to adapt to bottle openings of different sizes. When it is necessary to open the cap 2, lift the free end of the pressing part 7 upwards. The pressing part 7 rotates in the opposite direction around the bushing, driving the rotating shaft 8 to move upwards. The hook locking part 9 rotates around the rotating shaft 8 and disengages from the rectangular frame of the upper mounting part 6. Then, flip the cap 2 upwards. The cap 2 drives the upper mounting part 6 to flip around the rotating arm of the lower mounting part 5, and the stopper 4 comes out of the bottle opening 1, thus completing the opening of the cap 2.
[0032] If it is necessary to adjust the connection force between the upper mounting part 6 and the groove 3 of the cover 2, the free end of the pull strap 16 can be pulled to adjust the length of the pull strap 16 around the upper mounting part 6. After the force is appropriate, tighten the locking rod 14 so that the locking rod 14 presses against the pull strap 16 to achieve fixation.
[0033] You can also pull the free end of the pull strap 16 to adjust the length of the pull strap 16 around the upper mounting part 6. After the force is appropriate, tighten the locking rod 14 so that the locking rod 14 presses against the pull strap 16 to fix it, thereby further locking the lower mounting part 5.
[0034] It should be noted that the spring steel wires constituting the upper mounting part 6 and the lower mounting part 5 always have a tendency to expand outward.
