Description

Technical Field

[0001] This utility model relates to the technical field of commonly used laboratory containers, and in particular to a connection structure and a container. Background Technology

[0002] Commonly used glass containers in the laboratory, such as volumetric flasks, colorimetric tubes, and reagent bottles, are usually made of glass with separate stoppers and bottle bodies. This means that the stopper needs to be correctly installed onto the bottle opening during use. In some experiments, the stopper needs to be frequently opened and closed. If the stopper is not secured and is placed on the table and rolled around, it is easy for it to fall off and break.

[0003] Currently, most laboratories tie the stopper and bottle together with a rope, or store the stopper and bottle separately. The rope method is cumbersome, and the connection between the bottle and the stopper is not very stable. If they are stored separately, it is difficult to find a matching stopper later. Utility Model Content

[0004] The purpose of this invention is to improve the existing method of connecting the stopper and the bottle body by tying a rope, which is cumbersome and has poor stability, and to provide a connection structure and container.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The connecting structure includes: a connector and two locking members, wherein the two locking members are respectively installed at both ends of the connector, and each locking member has a locking position;

[0007] Each of the locking components includes an adjusting bar and a locking part. The locking part has a locking through groove and a plurality of first protruding teeth. The adjusting bar has a plurality of second protruding teeth. The locking through groove extends from a first end of the locking part to its second end. One end of the adjusting bar is mounted on the locking part, and the other end of the adjusting bar passes through the locking through groove and forms a locking position on the inner side of the adjusting bar. The plurality of first protruding teeth respectively engage with the plurality of second protruding teeth.

[0008] In one embodiment, the locking part has a relief groove, which is disposed near a first end or a second end of the locking part, and the relief groove communicates with the locking through groove.

[0009] The other end of the adjusting strip abuts against the bottom wall of the clearance groove.

[0010] In one embodiment, the clearance groove includes a first clearance groove and a second clearance groove, wherein the first clearance groove is disposed at the lower end of the locking part and the second clearance groove is disposed at the upper end of the locking part;

[0011] The number of the second clearance groove is two, and the two second clearance grooves are respectively disposed at the first end and the second end of the locking part.

[0012] In one embodiment, the locking part has a third protruding tooth and an elastic plate. The third protruding tooth is mounted on the elastic plate, and the elastic plate is disposed near the first end of the locking part. The third protruding tooth abuts against any one of the second protruding teeth.

[0013] The elastic plate is positioned above the first clearance groove.

[0014] In one embodiment, the cross-sections of the first tooth, the second tooth, and the third tooth are all triangular. The first tooth has two first abutting surfaces, the second tooth has two second abutting surfaces, and the third tooth has two third abutting surfaces. The first abutting surfaces and the third abutting surfaces abut against the second abutting surfaces, respectively.

[0015] The area of ​​the third contact surface is larger than the area of ​​the first contact surface.

[0016] In one embodiment, at least a portion of the first tooth, the second tooth, and the third tooth are made of an elastic material.

[0017] In one embodiment, the number of the second protrusions is greater than the number of the first protrusions.

[0018] In one embodiment, among the plurality of first protrusions, the volume of each first protrusion gradually decreases from the first end of the locking portion to its second end.

[0019] In one embodiment, the connector is a strip-shaped elastic component.

[0020] This utility model also proposes a container, including a bottle body, a bottle stopper, and a connection structure as described above, wherein the bottle stopper and the bottle body are respectively disposed in the locking positions of two locking members, and the inner wall of the adjusting strip abuts against the outer wall of the bottle stopper or the bottle body.

[0021] The technical solution provided by this utility model has the following advantages and effects:

[0022] Two locking components are fixed together by a connector. When one locking component is fixed to the bottle body, the other locking component restricts the range of motion of the bottle stopper, preventing it from slipping off the table. Furthermore, this locking component is structurally more stable than a binding rope. It features an adjusting strip and a locking part. One end of the adjusting strip passes through the locking groove, and the second protrusion of the adjusting strip engages with the first protrusion of the locking part to secure the bottle body or bottle stopper. Multiple first and second protrusions are present; any one of the second protrusions engages with the first protrusion to adjust the locking position, allowing different sized bottles and stoppers to be accommodated, thus improving the versatility of the connection structure.

[0031] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0032] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0033] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0034] This utility model proposes a connection structure 3, such as Figures 1 to 3 As shown, the device includes a connector 32 and two locking members 31. The two locking members 31 are respectively installed at both ends of the connector 32, and each locking member 31 has a locking position. Each locking member 31 includes an adjusting bar 312 and a locking part 311. The locking part 311 has a locking groove 310 and a plurality of first protrusions 3112. The adjusting bar 312 has a plurality of second protrusions 3121. The locking groove 310 passes through the first end 313 of the locking part 311 and extends to its second end 314. One end of the adjusting bar 312 is installed on the locking part 311, and the other end of the adjusting bar 312 passes through the locking groove 310. The plurality of first protrusions 3112 respectively engage with the plurality of second protrusions 3121.

[0035] Specifically, the two locking parts 31 are respectively used to fit onto the bottle stopper 2 and the bottle body 1. The two locking parts 31 are fixed by the connector 32. When one locking part 31 is fixed on the bottle body 1, the other locking part 31 clamps the bottle stopper 2, restricting the range of motion of the bottle stopper 2 and preventing the bottle stopper 2 from slipping off the table. Moreover, compared to the binding rope, the locking component 31 has a more stable structure. The locking component 31 has an adjusting bar 312 and a locking part 311. After one end of the adjusting bar 312 passes through the locking groove 310, the second protrusion 3121 of the adjusting bar 312 cooperates with the first protrusion 3112 of the locking part 311 to lock the bottle body 1 or the bottle stopper 2. There are multiple first protrusions 3112 and second protrusions 3121. Any second protrusion 3121 cooperates with the first protrusion 3112 to adjust the size of the locking position, so that bottle bodies 1 and bottle stoppers 2 of different sizes can be adapted to the locking component 31, thereby improving the versatility of the connection structure 3.

[0036] In some embodiments, the locking part 311 has a relief groove, which is disposed near the first end 313 or the second end 314 of the locking part 311 and communicates with the locking through groove 310; the other end of the adjusting strip 312 abuts against the bottom wall of the relief groove.

[0037] Specifically, a clearance groove is provided in the locking part 311 to allow the adjustment bar 312 to pass. At the first end 313 and the second end 314 of the locking part 311, the adjustment bar 312 has a large range of motion and can expand upward and outward. When the adjustment bar 312 is engaged with the locking part 311, the second protrusion 3121 of the adjustment bar 312 near the first end 313 or the second end 314 of the locking part 311 is more likely to separate from the first protrusion 3112. Under the action of external force, it is easier to adjust the tightness of the adjustment bar 312 and the locking part 311, making it easier for the adjustment bar 312 to disengage. After the external force is removed, the second protrusion 3121 and the first protrusion 3112 are normally engaged at the first end 313 or the second end 314 of the locking part 311, improving the clamping stability of the locking member 31.

[0038] Preferably, the clearance groove includes a first clearance groove 3114 and a second clearance groove 3115. The first clearance groove 3114 is disposed at the lower end of the locking part 311, and the second clearance groove 3115 is disposed at the upper end of the locking part 311. There are two second clearance grooves 3115, and the two second clearance grooves 3115 are respectively disposed at the first end 313 and the second end 314 of the locking part 311.

[0039] Specifically, the first clearance groove 3114 and the second clearance groove 3115 are respectively disposed at the upper and lower ends of the locking part 311, and the two second clearance grooves 3115 are respectively disposed at the first end 313 and the second end 314 of the locking part 311. The diameter of the two ends of the locking part 311 is larger, while the diameter of the middle section is smaller. The first protrusion 3112 at both ends of the locking part 311 and the corresponding second protrusion 3121 are loosely matched, making the engagement between the locking part 311 and the adjusting strip 312 more flexible.

[0040] Preferably, in order to further increase the stability of the engagement between the locking part 311 and the adjusting strip 312, the locking part has a third protrusion 3111 and an elastic plate 3113. The third protrusion 3111 is mounted on the elastic plate 3113. The elastic plate 3113 is disposed near the first end 313 of the locking part 311. The third protrusion 3111 abuts against any one of the second protrusions 3121. The elastic plate 3113 is disposed above the first clearance groove 3114.

[0041] Specifically, the third protruding tooth 3111 is used to engage with the second protruding tooth 3121 located at the first end 313 of the locking part 311. The third protruding tooth 3111 is installed on the elastic plate 3113. The elastic plate 3113 has a first clearance groove 3114 below. By pressing the elastic plate 3113 with a finger, the elastic plate 3113 drives the third protruding tooth 3111 to move downward, which facilitates the separation of the third protruding tooth 3111 from the second protruding tooth 3121 and improves the ease of operation of the adjusting strip 312.

[0042] Preferably, the cross-sections of the first protrusion 3112, the second protrusion 3121, and the third protrusion 3111 are all triangular. The first protrusion 3112 has two first abutting surfaces 31121, the second protrusion 3121 has two second abutting surfaces 31211, and the third protrusion 3111 has two third abutting surfaces 31111. The first abutting surfaces 31121 and the third abutting surfaces 31111 abut against the second abutting surfaces 31211 respectively. The area of ​​the third abutting surface 31111 is larger than the area of ​​the first abutting surface 31121.

[0043] Specifically, the first abutting surface 31121 of the first protrusion 3112 is used to abut against the second abutting surface 31211 of the second protrusion 3121. The area of ​​the third abutting surface 31111 is larger than the area of ​​the first abutting surface 31121. When the third protrusion 3111 and the second protrusion 3121 are engaged, the abutting area between the third protrusion 3111 and the second protrusion 3121 is larger, which can increase the stability after the third protrusion 3111 and the second protrusion 3121 abut against each other.

[0044] Preferably, at least a portion of the first protrusion 3112, the second protrusion 3121, and the third protrusion 3111 are made of elastic material. Specifically, the first protrusion 3112, the second protrusion 3121, and the third protrusion 3111 all have a certain degree of elasticity. When the adjusting strip 312 slides in the locking groove 310, a certain pulling force is applied to the other end of the adjusting strip 312. The first protrusion 3112 and the second protrusion 3121, and the third protrusion 3111 and the second protrusion 3121, squeeze each other, causing the adjusting strip 312 to move in the locking groove 310, thus improving the convenience of adjustment. When the pulling force disappears, the second protrusion 3121 of the adjusting strip 312 engages with the first protrusion 3112 and the third protrusion 3111 of the locking part 311, so that the locking part 31 is sleeved on the bottle body 1 or the bottle stopper 2.

[0045] Preferably, the number of second protrusions 3121 is greater than the number of first protrusions 3112. Specifically, the number of second protrusions 3121 is larger and greater than the number of first protrusions 3112, so that any one of the second protrusions 3121 on the adjusting bar 312 can cooperate with the first protrusion 3112, which facilitates the adjustment of the size of the locking position and improves the adaptability of the locking member 31.

[0046] Preferably, among the plurality of first protrusions 3112, the volume of each first protrusion 3112 gradually decreases from the first end 313 of the locking portion 311 to its second end 314. Specifically, the first protrusion 3112 near the first end 313 of the locking portion 311 has a larger volume, resulting in a larger contact area between the first protrusion 3112 and the second protrusion 3121, and relatively stable contact; the first protrusion 3112 near the second end 314 of the locking portion 311 has a smaller volume, resulting in a smaller contact area between the first protrusion 3112 and the second protrusion 3121, and relatively poorer contact stability. When the elastic plate 3113 is pressed downwards, and the other end of the adjusting strip 312 is pushed upwards into the clearance groove, the passage of the adjusting strip 312 within the locking through groove 310 can be greatly improved, facilitating the adjustment of the size of the locking position by the adjusting strip 312.

[0047] Preferably, after one end of the adjusting bar 312 passes through the locking part 311, a locking position is formed on the inner side of the adjusting bar 312; the second protrusion 3121 near the other end of the adjusting bar 312 engages with the first protrusion 3112, making the locking position larger; the second protrusion 3121 away from the other end of the adjusting bar 312 engages with the first protrusion 3112, making the locking position smaller. Specifically, after one end of the adjusting bar 312 passes through the locking part 311, the adjusting bar 312 forms a locking position. By pulling the end of the adjusting bar 312, the size of the locking position is adjusted, further improving the adaptability of the locking member 31.

[0048] Preferably, the connector 32 is a strip-shaped elastic component. Specifically, the connector 32 is an elastic component, which improves the flexibility of the connector 32 and the flexibility of the two locking components 31 at both ends of the connector 32.

[0049] This utility model also proposes a container 100, including a bottle body 1, a bottle stopper 2, and a connecting structure 3 as described above. The bottle stopper 2 and the bottle body 1 are respectively disposed in the locking positions of two locking members 31, and the inner wall of the adjusting strip 312 abuts against the outer wall of the bottle stopper 2 or the bottle body 1. Specifically, this connecting structure 3, combined with the bottle body 1 and the bottle stopper 2, forms a convenient utensil structure. The range of motion of the bottle stopper 2 is restricted to prevent it from slipping off the table. At the same time, it can also be applied to bottle body 1 structures of different sizes. The bottle stopper 2 has a fitting part 21 and a stopper head 22. The fitting part 21 and the stopper head 22 are an integral structure. The fitting part 21 is fitted by the locking member 31, and the stopper head 22 is used to seal the opening of the bottle body 1.
