Description

Suitable for anti-loosening fixing structure of flange mouth bottle Technical Field

[0001] The utility model relates to a fixing structure, in particular to an anti-loosening fixing structure suitable for a flange-mouth bottle body. Background Art

[0002] Currently, conventional syringes use a fixed body to secure the medication bottle. However, due to tolerances, the bottle often moves up and down or side to side relative to the fixed body when subjected to external forces. Consequently, if the external force is strong, there is a risk of impact and breakage. Relying solely on filling tolerances can easily result in an interference fit during assembly, causing the bottle to not fit properly.

[0003] At the same time, in order to limit the position of the bottle body, the existing technology 202010947075.6 has modified the installation inner sleeve. Specifically, "a syringe fixing barrel is provided on the top of the installation inner sleeve, and a fixing claw is provided in the syringe fixing barrel for fixing the fixing flange of the syringe barrel; in order to facilitate the insertion of the fixing flange, the upper surface of the fixing claw is provided with an inclined surface, and the outer side of the fixing claw is connected to the wall surface of the syringe fixing barrel; when the fixing flange is inserted, the fixing claw is flipped downward around the outer fixing part to smoothly insert the fixing flange. "Such a structure can only achieve simple longitudinal limitation of the bottle body and cannot perform lateral displacement restraint. Moreover, when the fixing flange is inserted, the fixing claw may be stuck, resulting in the inability to smoothly install the bottle body.

[0004] Similarly, the prior art 202021975875.0 also adopts a similar structure and also has the above-mentioned defects.

[0005] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create an anti-loosening fixing structure suitable for flange-mouth bottles, making it more valuable for industrial use.

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] As shown in Figures 1 to 5 , the anti-loosening fixing structure for flange-mouth bottles includes a fixing body 1, within which a bottle 2 is mounted, and a flange structure 8 disposed at the upper end of the bottle 2. The structure is unique in that a limit ring 3 is disposed at the upper end of the fixing body 1, on which mirror-image side limiter assemblies 4 are mounted. The side limiter assemblies 4 define a storage space for the upper end of the bottle 2. This effectively limits the side positions of the upper end of the bottle 2 after the bottle 2 is successfully inserted, preventing unnecessary lateral movement. Furthermore, an elastic support structure 5 is disposed at the upper end of the fixing body 1, within the storage space at the upper end of the bottle 2, to properly support the upper end of the bottle 2 and ensure bottom positioning of the upper end of the bottle 2. Furthermore, a guide ring 6 extends from the upper end of the fixing body 1, on which mirror-image upper limiter assemblies 7 are mounted. The flange structure 8 contacts the upper limiter assemblies 7. Therefore, after the bottle body 2 is placed in place, its upper end is simultaneously clamped and limited in three directions by the side limiting assembly 4, the elastic support structure 5, and the upper end limiting assembly 7, and will not become loose.

[0029] In accordance with a preferred embodiment of the present invention, the side stop assembly 4 is an elastic stop block. Specifically, the elastic stop block is a rectangular plate-shaped block with a circular chamfered top. This prevents scratches on the hands during manual assembly and prevents unnecessary interference with other components during assembly and use.

[0030] Furthermore, the elastic support structure 5 employed in the present invention is an elastic support arm. This provides effective rebound support during assembly, even if the upper end of the bottle body 2 is excessively pressed, preventing it from overextending into the fixed body 1 and becoming stuck. Specifically, the elastic support arm comprises an elastic crosspiece 9 connected to the fixed body 1. An arm body 10 is vertically mounted on the elastic crosspiece 9, and a support block 11 is disposed at the upper end of the arm body 10. Thus, any downward stress on the bottle body 2 is relieved by the deformation of the elastic crosspiece 9. This allows for moderate rebound, providing optimal support.

[0031] In actual implementation, the upper end stopper assembly 7 is a slanted stopper with an oblique contact slope at its bottom. This allows for appropriate elastic deformation as the bottle 2 passes through, causing the slanted stopper to squeeze to the sides. Once the bottle 2 has fully entered the fixed body 1, the slanted stopper returns to its original position, with the oblique contact slope positioned precisely at the top of the upper end of the bottle 2, effectively limiting the position. This allows for timely longitudinal stoppering of the bottle 2 after it is properly installed.

[0032] Looking further, considering the different positioning requirements of the bottle body 2, the flange structure 8 adopted is a round-mouth flange or a cut-out flange. Thus, the round-mouth flange or the cut-out flange is used in conjunction with the side limiting assembly 4, the elastic support structure 5, and the upper end limiting assembly 7 to achieve better positioning. During assembly, there is no need to pay attention to the direction of the bottle body 2 with a round-mouth flange, and the straight edge of the bottle body 2 with a cut-out flange can be parallel to the elastic support structure 5. In addition, it should be noted that the flange structure 8 adopted in the present invention can also adopt a variety of structures such as semicircular and hexagonal. As long as the flange structure has an outer shape larger than the upper end opening of the container, it is applicable to the present invention and will not be repeated here. At the same time, a suitable limiting ring structure can be selected according to the corresponding outer shape of the flange structure 8.

[0033] The working principle of this utility model is as follows:

[0034] Insert the bottle body 2 into the fixed body 1, and then apply force to the bottle body 2. The upper limit assembly 7 will be deformed after being subjected to the force, and it will move closer to the two sides of the guide ring 6 to form a clearance space. As the force is applied to the bottle body 2, the flange structure 8 passes through the clearance space and contacts the elastic support structure 5. At the moment of contact, the elastic support structure 5 is deformed due to the stress impact and immediately resets and rebounds, limiting the further movement of the flange structure 8. Finally, the upper limit assembly 7 and the elastic support structure 5 can limit the upper and lower positions of the flange structure 8, thereby ensuring that the entire bottle body 2 does not shake up and down. At the same time, relying on the lateral limit of the side limit assembly 4, no lateral shaking will occur.

[0035] It can be seen from the above text description and the accompanying drawings that the present invention has the following advantages:

[0036] 1. The three-way clamping and limiting of the side limit assembly, elastic support structure and upper limit assembly can ensure the stable combination of the bottle body and the fixed body without shaking.

[0037] 2. The upper end limit assembly can guide the flange structure forward and limit it after the flange structure is in a suitable position, satisfying the irreversible guide limit and ensuring that the bottle body cannot loosen from the fixed body.

[0038] 3. It is equipped with an independent elastic support structure to meet the requirements of assembly stress absorption and achieve effective downward limit, which can provide stable bottom support for the flange structure.

[0039] 4. The overall structure is simple, the existing fixed body can be modified and replaced, and it is suitable for various conventional syringe structures and has good versatility.
