Abstract
Description
Technical Field
[0001] This utility model relates to the field of connecting cable technology, specifically an adjustable connecting cable and a glass vessel. Background Technology
[0002] Many laboratory glasswares consist of bottles paired with a sealing stopper. Taking volumetric flasks as an example, laboratories use a large number of volumetric flasks. Each bottle body and its matching sealing stopper are a set, so the bottle body and sealing stopper must be connected and tied together with a rope to ensure that the stopper is used correctly and that they are matched one-to-one, making them convenient to use.
[0003] However, a large number of volumetric flasks need to be tied manually, which is very time-consuming. Everyone ties them differently, which leads to many drawbacks: if the flasks are tied too long, they are not easy to use; if they are tied too short, they are also not easy to use; if they are not tied tightly, they are easy to fall off during use; and if the knots are tied, loose threads will leave behind, affecting their use.
[0004] To address the aforementioned issues, this technical field has developed numerous related products, but these products still have limitations in their use. For example, while there are many specifications ranging from 1 ml to 1000 ml, they can only accommodate certain sizes. Furthermore, their design principle utilizes the elasticity of a ring material to adjust the size and connect the bottle body and stopper, but laboratory glassware is often used in highly corrosive environments with strong acids and alkalis, which can compromise the stability of the elastic material.
[0005] Based on this, the present invention designs an adjustable connecting cable and a glass container to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide an adjustable connecting cable and glassware to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, the utility model provides the following technical solution: an adjustable connecting cable, including a chain, wherein anti-reverse joints are provided at intervals along the length direction on the outer wall of the chain, and both ends of the chain are bent into a ring and respectively connected to positioning sleeves, wherein the positioning sleeves at both ends are respectively sleeved on the chain to form two independent collars that can be used to fasten items, and the tightness of the collars can be adjusted by moving the positioning sleeves forward and backward.
[0008] As a preferred embodiment, the anti-reverse joint is a unidirectional anti-reverse cone structure, and the anti-reverse joints distributed on the left and right halves of the chain face opposite directions, with the anti-reverse direction of the anti-reverse joints distributed on the left and right halves of the chain facing the middle of the chain.
[0009] As a preferred embodiment, the positioning sleeve includes a tapered sleeve body, the tapered sidewall of which is provided with a plurality of elastic slits at intervals, the large diameter end of the tapered sleeve body is open and the small diameter end is provided with a limiting hole, and the plurality of elastic slits extend to the limiting hole.
[0010] As a preferred embodiment, the diameter of the limiting hole is larger than the diameter of the chain and smaller than the outer diameter of the anti-reverse joint.
[0011] As a preferred embodiment, the adjustable connecting cable is made entirely of polypropylene material.
[0012] A glass vessel includes a detachable bottle body and a sealing plug, the bottle body and the sealing plug being connected by an adjustable connecting cable as described above.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] This utility model's adjustable connecting cable mainly includes a chain, a backstop, and positioning sleeves. The positioning sleeves at both ends are respectively fitted onto the chain, forming two independent loops that can be used to secure items. The positioning sleeves can be quickly tightened by pulling between the backstops or loosened by manual unlocking. The operation is simple and the connection is reliable, suitable for bundling and connecting items of different diameters. In particular, this utility model uses an adjustable connecting cable made of polypropylene material for connecting laboratory glassware, and can be used stably in most strong acid, strong alkali, and highly corrosive environments.

[0020] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0021] Example 1
[0022] Please see Figure 1-3 The utility model provides a technical solution:
[0023] An adjustable connecting cable and glassware,
[0024] It includes a chain 10, and anti-reverse joints 20 are provided at intervals along the length direction on the outer wall of the chain 10.
[0025] like Figure 2 As shown, the anti-reverse joint 20 is a one-way anti-reverse cone structure. The anti-reverse joints 20 distributed on the left and right halves of the chain 10 face opposite directions. The anti-reverse joints 20 distributed on the left and right halves of the chain 10 face the middle side of the chain 10 in the anti-reverse direction. The anti-reverse joints 20 can be set throughout the left and right halves. However, if the chain 10 is long and the anti-reverse joints 20 in the middle part are not within the actual adjustment stroke range, the anti-reverse joints 20 on the outer wall of the middle part of the chain 10 may not be provided.
[0026] like Figure 3 As shown, both ends of the chain 10 are bent in a ring shape and connected to positioning sleeves 30 respectively. The positioning sleeve 30 includes a conical sleeve 31. The conical sidewall of the conical sleeve 31 is provided with several elastic slits 32 at intervals. The large diameter end of the conical sleeve 31 is open and the small diameter end is provided with a limiting hole 33. The elastic slits 32 extend to the limiting hole 33.
[0027] The positioning sleeves 30 at both ends are respectively fitted onto the chain 10 to form two independent loops 40 that can be used to fasten items. The tightness of the loops 40 can be adjusted by moving the positioning sleeves 30 forward and backward, so that they can be used to tie and connect items of different diameters.
[0028] Specifically, since the cone tip of the anti-reverse joint 20 can open the limiting hole 33 and pass through it, the positioning sleeve 30 can freely pass through the anti-reverse joint 20 only when the chain 10 with the anti-reverse joint 20 moves toward the end. When moving in the opposite direction, the small diameter end of the positioning sleeve 30 needs to be opened so that the limiting hole 33 can be enlarged and the positioning sleeve 30 can pass through the limiting hole 33. This allows the positioning sleeve 30 to move unidirectionally on the chain 10, thereby achieving quick connection and tightening, and preventing loosening during daily use without human intervention.
[0029] Example 2
[0030] Based on Example 1, in order to facilitate the use of the adjustable connecting cable in special environments, the adjustable connecting cable is made entirely of polypropylene material. Specifically, in this example, a glassware is disclosed, including a separable bottle body and a sealing plug, which are connected by the adjustable connecting cable of Example 1. Since polypropylene material has good corrosion resistance, weather resistance and plasticity, it can be used stably in most strong acid, strong alkali and highly corrosive environments.
