Description

Technical Field

[0001] This utility model belongs to the field of bottle caps, specifically relating to a quick-connect structure and container. Background Technology

[0002] Currently, there are various connection structures available in the bottle cap industry. Traditional connection structures are mostly threaded or three-point or four-point snap-fit ​​structures.

[0003] However, in the bottle cap industry, threaded connections are used, but this method requires the thread to be rotated one or more times to achieve a secure fit, which is inconvenient. Three-point or four-point snap-fit ​​structures are also used, but due to their complex structure, molds that match the three-point or four-point snap-fit ​​structure are usually designed during injection molding, resulting in complex mold manufacturing and higher production costs.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. The quick-connect structure of this utility model includes a first ring and a second ring that matches the first ring. The direction in which the second ring covers the first ring is the covering direction, and the surface of the second ring close to the first ring along the covering direction is the lower surface of the second ring. It also includes two mounting platforms on the second ring, symmetrically arranged on the lower surface of the second ring, and each platform engages with two slide rails. Each slide rail has a positioning post on its lower surface. Each mounting platform has a mounting platform slot that matches the positioning post. Each mounting platform slides with the slide rail through a first gap. The second ring contacts the surface of the first ring. When each mounting platform slides with the slide rail, the outer circumferential surface of the mounting platform is compressed by the positioning post. The rings deform sequentially until the pressure on the outer circumference of the mounting platform disappears and it recovers. At this point, the positioning post engages with the mounting platform slot to fix the second ring and the first ring. The purpose of this invention is to fix the first ring and the second ring in both axial and circumferential directions by having the mounting platform engage with the positioning post. In addition, there are only two mounting platforms and two slide rails. Therefore, compared with the three-point or four-point snap-fit ​​structures in the prior art, it is simpler to manufacture and more cost-effective. Furthermore, unlike the existing spiral method, which requires a full turn or more, the cooperation between the mounting platform and the slide rail allows the connection structure to rotate less than one revolution during engagement. In this embodiment, a 45° rotation is sufficient.

[0019] 2. Because of the quick-connect structure in this utility model, the first ring has two fixing blocks, which are symmetrically fixed on the inner sidewall of the first ring. Each fixing block and the end of the slide rail form an inlet on the inner sidewall of the first ring. The inlet matches the first gap, and the size of the inlet is smaller than the size of the first gap. The inlet and the mounting plate both extend along the circumference of the first ring, and the extension length of the inlet is greater than the extension length of the mounting plate. The purpose is that the mounting plate can enter the first ring through the inlet and match the slide rail so as to cooperate between the first ring and the second ring.

[0020] 3. Due to the quick-connect structure in this utility model, each mounting platform has a mounting platform base, which is fixed vertically downward to the lower surface of the second ring; a mounting platform bending portion, which is integrally formed with the mounting platform base and extends outward along the radial direction of the second ring; a mounting platform slot is provided on the mounting platform bending portion; the side of the first ring and the lower surface of the second ring that are close together is used as the upper surface of the first ring; each slide rail has an upper surface, a lower surface and a circumferential surface along the covering direction; each mounting platform bending portion has an upper surface along the covering direction, which slides in cooperation with the lower surface of the slide rail; each slide rail... A second gap exists between the upper surface and the upper surface of the first ring. The circumference of the second ring containing the second gap slides in conjunction with the circumference of the slide rail. The lower surface of the first ring slides in conjunction with the upper surface of each slide rail. The purpose is to utilize the three-way cooperation of the upper surface of the hanging platform bending part sliding in conjunction with the lower surface of the slide rail, the circumference of the second ring containing the second gap sliding in conjunction with the circumference of the slide rail, and the lower surface of the first ring sliding in conjunction with the upper surface of each slide rail to improve the cooperation effect of the first ring and the second ring.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example 1 like Figure 1-2 As shown, a quick-connect structure includes a first ring 1 and a second ring 2 that matches the first ring 1. The direction in which the second ring 1 covers the first ring 1 is designated as the covering direction A. The surface of the second ring 2 that is close to the first ring 1 along the covering direction A is designated as the lower surface of the second ring. The first ring 1 has two slide rails 11, which are symmetrically arranged on the inner wall of the first ring 1, and the two slide rails 11 form a first gap on the circumference of the first ring 1. The second ring 2 has two mounting platforms 21, which are symmetrically arranged on the lower surface of the second ring and cooperate with the two slide rails 11. The lower surface of each slide rail 11 has a positioning post 111 (it should be noted that a channel is formed between the slide rail 11 and the inner wall of the first ring 1, and the positioning post 111 extends downward along the covering direction A to the channel). Each mounting platform 21 has a mounting platform slot 211 that matches the positioning post; each mounting platform 21 slides with the slide rail 11 through a first gap, and the second ring 2 contacts the surface of the first ring 1. When each mounting platform 21 slides with the slide rail 11, the outer circumferential surface of the mounting platform 2 is compressed by the positioning post 111 and deforms sequentially; until the compressive force on the outer circumferential surface of the mounting platform 2 disappears and it returns to its original state, the positioning post 111 is inserted into the mounting platform slot 211 to fix the second ring 2 and the first ring 1; the purpose is to use the mounting platform slot 211 is secured within the positioning post 111, thus fixing the first ring 1 and the second ring 2 in both axial and circumferential directions. Furthermore, there are only two mounting platforms and two slide rails. Therefore, compared to the three-point or four-point snap-fit ​​structures in the prior art, it is simpler to manufacture and more cost-effective. In addition, unlike the existing spiral method, which requires a full turn or more, the cooperation between the mounting platform and the slide rail allows the rotation range of this connection structure to be less than one turn during engagement. In this embodiment, a rotation of 45° is sufficient.

[0025] Each slide rail 11 has its sidewall along the closing direction A matched with the circumferential surface of the first ring 1; each mounting platform 21 has its sidewall along the closing direction A matched with the second ring 2.

[0026] The positioning post 111 extends downward along the closing direction A; the mounting slot 211 extends radially along the second ring.

[0027] The first ring 1 has two fixing blocks 8, which are symmetrically fixed on the inner sidewall of the first ring 1. Each fixing block 8 and the end of the slide rail 11 form an inlet 7 on the inner sidewall of the first ring 1. The inlet 7 and the mounting platform 21 both extend along the circumference of the first ring 1. The inlet 7 matches the first gap, and the size of the inlet 7 is smaller than the size of the first gap. The extension length of the inlet 7 is greater than the extension length of the mounting platform 21. Specifically, the two inlet 7, the two fixing blocks 8, the two slide rails 11, and the two positioning posts 111 are symmetrically arranged in a 180° rotational array on the circumference of the first ring 1. The two mounting platforms 21 are symmetrically arranged in a 180° rotational array on the second ring 2. The two inlet 7, the two fixing blocks 8, and the two slide rails 11 are arranged on the circumference of the first ring 1 in the manner of one inlet 7, one fixing block 8, one slide rail 11, the other inlet 7, the other fixing block 8, and the other slide rail 11. In operation, the two mounting platforms 21 on the second ring 2 are roughly aligned with the inlet 7 of the first ring 1 (it should be noted that the inlet 7 is connected to the channel). A start marker 9 and an end marker 10 are set on the upper surface of the first ring 1. The second ring 2 includes a second ring base and a second ring flange. The lower surface of the second ring base is fixed to the second ring flange, and the two mounting platforms are installed on the lower surfaces of the two second ring flanges. The upper surface of the second ring flange... A second circular mark 22 is set on the surface. After the second circular ring 2 is inserted into the first circular ring 1, the second circular mark 22 corresponds to the starting mark 9. At this time, rotating clockwise, the mounting platform 21 cooperates with the slide rail 11, and the mounting platform 21 is deformed by the pressure of the positioning post 111 until the mounting platform 21 moves into the mounting platform slot 211 and is engaged in the positioning post 111, thus completing the axial and circumferential fixation; and at this time, the second circular mark 22 corresponds to the ending mark 10. Each mounting plate 21 has A mounting base 212 is fixed vertically downward to the lower surface of the second ring 2; a mounting bend 213 is integrally formed with the mounting base 212 and extends outward in the radial direction of the second ring 2; a mounting slot 211 is provided on the mounting bend 213; the side of the first ring 1 that is close to the lower surface of the second ring is used as the upper surface of the first ring; each slide rail 11 has an upper surface, a lower surface, and a circumferential surface along the covering direction A; each mounting bend 213 has an upper surface along the covering direction A, which slides in cooperation with the lower surface of the slide rail; each upper surface of the slide rail is in contact with the upper surface of the first ring. A second gap exists, and the circumferential surface of the second ring 2 where the second gap is located slides in contact with the circumferential surface of the slide rail 11; the lower surface of the first ring slides in contact with the upper surface of each slide rail. The main purpose is to utilize the three-way cooperation of the upper surface of the hanging platform bending part sliding in contact with the lower surface of the slide rail, the circumferential surface of the second ring 2 where the second gap is located sliding in contact with the circumferential surface of the slide rail 11, and the lower surface of the first ring sliding in contact with the upper surface of each slide rail 11, so as to improve the cooperation effect of the first ring 1 and the second ring 2. Combined with the sealing of the positioning post 111 in the hanging platform slot 211, the sealing performance of the first ring 1 and the second ring 2 after connection is improved.

[0028] Each slide rail 11 has a slide rail bend 112, which extends along the axial direction of the second ring 2 and matches the end face of the mounting platform 21. When the positioning post 111 engages with the mounting platform slot 211, the vertical side of the slide rail bend 112 engages with the end face of the mounting platform 21. The purpose is to ensure that when the positioning post 111 is locked inside the mounting platform slot 211, the best engagement between the vertical surface of the slide rail bend 112 and the end of the mounting platform 21 is a close fit. This allows for a second seal after the mounting platform slot 211 and the positioning post 111 have engaged and sealed, and then the end of the mounting platform 21 is fitted onto the slide rail bend 112 for a second seal, resulting in better sealing performance.

[0029] Example 2 like Figure 3-13 As shown, a container includes the quick-connect structure of Embodiment 1.

[0030] The container includes an upper cover 3 and a lower cover 4. A second ring 2 is fixed to the upper cover 3 in the opposite direction of the closing direction A, and a first ring 1 is fixed to the lower cover 4 in the closing direction A.

[0031] By adopting the above scheme, the upper cover 3 and the lower cover 4 can be fixed. This can be achieved by the two mounting platforms of the upper cover cooperating with the corresponding slide rails of the lower cover, and by the slots on the mounting platforms engaging with the positioning pins on the lower cover, thereby fixing the upper cover and the lower cover in the axial and circumferential directions.

[0032] The final surface of the upper cover 3 extending in the opposite direction of the closing direction A is the upper surface of the upper cover. The upper surface of the upper cover is provided with a spring-loaded button 5 and a discharge valve 6. The upper cover 3 and the lower cover 4 are fixed into a combination. The interior of the combination has a combination chamber. The combination chamber is isolated from or connected to the outside of the combination through the spring-loaded button 5 and the discharge valve 6. When the spring-loaded button 5 is pressed, the spring-loaded button 5 collapses and deforms downward, the combination chamber is compressed, the pressure increases until the discharge valve 6 opens, and the material in the combination chamber is discharged. When the pressure is released, the discharge valve 6 closes and the spring-loaded button 5 returns to its original state.

[0033] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
