Rubber band case

Abstract

The utility model discloses a rubber chain box, it includes two shell that mutually buckles, is equipped with the support surface that lets rubber chain wind in the shell, and rubber chain can stretch out from the shell and be clamped by two shell edges. Since rubber chain is placed in the inside of shell, and free end stretches out shell and is clamped by two shell edges, rubber chain will not easily scatter to the desktop and cause pollution, and after cutting off after pulling out rubber chain from between two shell, can be hung on the hook on the tooth surface directly, generally need not pass through disinfection treatment, convenient to use.

Description

Technical Field

[0001] This utility model relates to a chain box, and more particularly to a rubber chain box for orthodontic treatment. Background Technology

[0002] During orthodontic treatment, dentists often use rubber chains. These chains are primarily made of silicone and have a series of evenly distributed through-holes. The chain is fastened to hooks pre-fixed to the tooth surface through these holes, and the elasticity of the chain gently pulls the teeth into the correct position. However, current rubber chains are typically wrapped around ordinary I-beam rollers. During use, the chain easily detaches from the rollers and spills onto the work surface, causing unnecessary contamination and making it inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a rubber chain box that can effectively prevent the rubber chain from falling off and becoming contaminated, and is also convenient to use.

[0004] The present invention achieves the above objectives as follows:

[0005] A rubber chain box includes two interlocking housings, each housing having a support surface for winding a rubber chain, the rubber chain extending from the housing and being clamped by the edges of the two housings.

[0006] The supporting surface is the outer ring of the bearing, and a connecting shaft fixed to the inner ring of the bearing is provided in the middle of one of the housings.

[0007] The free end of the connecting shaft is provided with a barb, which passes through the central hole of another housing and is fastened to the outside of the central hole.

[0008] The edges of the two shells are tightly connected.

[0009] The edge of the housing is equipped with a saw blade for cutting rubber chains.

[0010] The saw blade is mounted on one of the housings, and a notch is opened at the opposite position on the other housing.

[0011] The size of the notch is approximately the size of a human finger.

[0012] The beneficial effects of this invention are: since the rubber chain is placed inside the housing, with its free end extending out of the housing and clamped by the edges of the two housings, the rubber chain will not easily fall onto the table and cause contamination. After the rubber chain is pulled out and cut between the two housings, it can be directly hung on the hook on the tooth surface. Generally, it does not require sterilization and is convenient to use. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] Figure 1 This is the front view of this utility model;

[0015] Figure 2 yes Figure 1 The left view;

[0016] Figure 3 yes Figure 1 AA sectional view. Detailed Implementation

[0017] Reference Figure 1 The rubber chain holder includes two interlocking housings 1. Each housing 1 has a support surface 3 for winding a rubber chain 2. The rubber chain 2 extends from within the housing 1 and is held between the edges of the two housings. Because the rubber chain 2 is housed inside the housing 1, it will not easily spill onto the table and cause contamination. After pulling the rubber chain 2 out from between the two housings 1 and cutting it, it can be directly hung on a hook on the dental surface. Generally, no sterilization is required, making it convenient to use.

[0018] The supporting surface 3 is the outer ring of the bearing, and a connecting shaft 5 fixed to the inner ring 4 of the bearing is provided in the middle of one of the housings 1. If a longer rubber chain 2 needs to be pulled out, the rubber chain 2 wrapped around the supporting surface 3 will rotate, thereby ensuring that the rubber chain 2 can be pulled out from the same position on the edge of the housing, further facilitating use.

[0019] To ensure a secure connection between the two housings, the free end of the connecting shaft 5 is provided with a barb 6, which passes through the central hole 7 of the other housing 1 and is fastened to the outside of the central hole 7. Of course, the two housings can also be glued or welded together.

[0020] The two shells 1 have a disc-shaped structure with their two edges tightly connected. This design ensures that the edges of the shells are secured with rubber chains 2, preventing items from falling into the shells or loosening and falling onto surfaces, thus avoiding inconvenience or contamination.

[0021] To further facilitate use, the edge of the housing 1 is provided with a saw 8 for cutting the rubber chain 2. When the rubber chain 2 is pulled out to the appropriate length, the saw 8 on the housing 1 can be used to cut the rubber chain 2, eliminating the need to use scissors or other knives to cut it.

[0022] In addition, the saw blade 8 is mounted on one of the housings 1, and a notch 9 is opened at the opposite position of the other housing 1. The notch 9 facilitates the cutting of the rubber chain 2 and also allows the cut rubber chain to be pulled out to other positions of the housing, so that the two housings can clamp the rubber chain 2 again.

[0023] Furthermore, to further facilitate the doctor's operation, the size of the notch 9 is approximately the size of a human finger.
