Description

Multi-Toothed Valve Molded Rubber Stoppers and Rubber End Connections

The present invention is a rubber stopper and a rubber connector to which a multi-toothed valve is applied. More specifically, a multi-toothed valve shaped rubber stopper that pursues the accuracy of the experiment and the safety and convenience of the user by using the compression and adhesion of the multi-toothed valve And to rubber connectors.

In general, when the inlet of the test tube or flask is blocked, the inlet of the test tube and the rubber stopper should be used for the accuracy and safety of the experiment, and in some cases, the inlet of the test tube should be blocked with a strong force. In addition, it is difficult to prevent due to dyes such as breakage or injury of the test tube, which may be caused by the user's excessive force, but it may be difficult to remove it again. When it is necessary to bend it, the existing method is used by applying heat with alcohol lamp or gas torch lamp. However, inexperienced experimenters may inadvertently cause a fire or burn, and the bending is not constant and breaks well. 1 and 2, the conventional test tube and plastic Fig. 1 shows a rubber stopper such as a gasket, which is simply a conical rubber stopper 1 having a certain size and a rubber stopper having a predetermined size so that a glass tube (or other laboratory equipment) can be inserted into the inner diameter part 2 of the central part thereof. The rubber stopper is difficult to be selected by the user due to the difference between the entrance and the diameter of the test tube and the adhesiveness, and to use the rubber stopper having a diameter larger or smaller than the standard of the test tube. If the user applies excessive force, the test tube or glass tube may be damaged or injured.In addition, even after disassembling the rubber stopper, the accuracy of the test is remarkable due to the poor sealing performance due to the poor fit or the poor fit. In addition, the hole 2 is drilled in the center of the rubber stopper, so that When using a test device for the purpose (hereinafter referred to as glass tube), the crimping and adhesiveness due to the difference between the inner diameter of the glass tube and the perforated rubber stopper is not constant, and the accuracy of the experiment is notably reduced, and the glass tube and the rubber stopper are pressed and adhered. When using a glass tube with a large diameter in order to improve the quality, too much force is applied, which is also a problem of damage or injury, and there is a problem in that it is difficult to prevent a safety accident. In addition, Figures 3 and 4, The multi-toothed valve shaped rubber stopper and the multi-toothed valve molded rubber connector according to the design of the present invention have been registered by the present applicant utility model registration (Utility Model Registration No. 20-186735), 3, the multi-toothed valve 4 having a predetermined size in the rubber stopper outer diameter part 6 and the rubber stopper inner diameter part 5 in the case of FIG. By molding, the stopper can be opened and closed safely and easily with little force, and the multi-toothed valve made of rubber for the molded rubber stopper 3 and the container 10 or the molded rubber stopper 3 and the glass tube 9 Is pressed or adhered uniformly so as to prevent the outflow of contents (gas or liquid). In addition, upper and lower ends of the molded rubber stopper 3 allow the user to insert the glass tube more easily. With wider inclined openings 7, 8 than. In addition, the multi-toothed valve 4 made of rubber of the inner diameter part 5 is in close contact with the glass tube 9 in multiple stages to prevent gas or liquid from leaking into the gap between the glass tube 9 and the rubber stopper. In addition, even if a narrow glass tube (9) or a thick glass tube (glass tube dotted line) is selectively used within a certain limit regardless of the diameter of the glass tube, the size of the multi-toothed valve has the same effect. The molded rubber stopper 3 has an upper end portion having a larger diameter than the lower end portion, and the molded rubber shape of the multi-toothed valve 4 has an outer diameter portion 6 gradually decreasing from the lower portion toward the upper portion, and the inner diameter portion 5 ) Is designed to have a size of a certain size. Figure 4 relates to a conventional I-shaped multi-toothed valve molded rubber connector, which is used when connecting test tubes or glass tubes. It is. To describe this in detail, the inner diameter portion 12 of the multi-toothed valve-shaped rubber connector 11 in which the glass tube is inserted into close contact with the inner diameter portion 12 for inducing a user to easily insert the test tube or the glass tube 9 into the inner diameter portion 12. A multi-toothed valve comprising a wider inclined right and left openings 13 and 14 and a metal or aluminum casing 15 for supporting the molded rubber connector 11 to prevent it from expanding or escaping to the outside is applied. It is easier to connect and dismantle, and to prevent the outflow of the moving fluid (gas or liquid), and the I-shape of the molded rubber connector has a flexible tube 16 applied to the center of the connector. It is designed to be able to adjust the angle (0 ° ~ 89 °) at the time of connection. Such a multi-tooth valve valve rubber stopper and a multi-tooth valve valve rubber end connection are experimental devices. In the case of mounting and using, since the part fixing the test tube is simply formed in the tooth shape, the test tube can be moved back and forth, left and right. Also, in the case of the conventional rubber stopper and the multi-tooth valve valve rubber stopper, the upper end is wide and the lower end is narrow conical column. Because of its shape, it is a phenomenon that the plug is easily detached due to the crimping and adhesion with the experimental container, and the safety and accuracy of the experiment tends to be somewhat deteriorated.

Accordingly, an object of the present invention is to solve the above problems, by forming a multi-toothed valve in the outer diameter of the molded rubber stopper, and to the inner diameter by molding a variety of multi-toothed valves in the sawtooth deformation stage to facilitate opening and closing of the rubber stopper The present invention provides a multi-toothed valve molded rubber stopper and molded rubber connector to increase the safety and precision by increasing the compression and adhesiveness with a small force while providing flexibility in size application within the limit. Multi-toothed valves are molded in the inner diameter of the silver molded rubber connector to improve flexibility and detachability, as well as to increase the crimping and adhesiveness of the glass tube when the glass tube is inserted and connected. To improve the quality and safety of experiments. It shall have the ease of inducing such that by placing a molding or molded rubber stopper rubber upper and lower ends or left and right sides of the fitting inner diameter portion larger than a certain opening portion to the side portion of the inner diameter (or groove) glass tube easily inserted.
