Anti-shake structure of electric needleless injector for livestock

Abstract

The utility model discloses an anti-shake structure of an electric needleless injector for livestock. The anti-shake structure provides two more optimized functions that the risk of falling off is reduced when the anti-shake structure is externally connected with a needle tube or a long medicine bottle and the like. When a machine generates vibration, the anti-shake rubber ring can disperse part of force through the flexible connection at the position, so that an external connection piece which is regarded as a force arm cannot fall off easily. And the internal waterproof rubber ring can be effectively prevented from loosening. Due to the fact that the fixing mode of the liquid inlet pipe and the internal metal piece is rigid connection containing the rubber ring, if the liquid inlet pipe is then in rigid connection with the shell, dislocation or leakage of the position with the rubber ring is possibly caused by vibration, and then the rubber ring loses efficacy, and flexible connection between the liquid inlet pipe and the shell is very important.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of veterinary medical instruments, and specifically relates to a kind of anti-shake structure of veterinary electric needleless injector. BACKGROUND

[0002] The needleless injector is a kind of veterinary medical instrument, to replace injection needle, so as to achieve the purpose of saving needle cost, reducing injection time, injection difficulty and preventing cross infection.

[0003] The device uses pneumatic, hydraulic, electric and other ways to spray the internal liquid through a small nozzle, forming a high-speed high-pressure jet stream, so that the liquid can penetrate very thick skin to reach the required position such as subcutaneous and intradermal.

[0004] The existing needleless injector is pneumatic and electric. The pneumatic type has the disadvantage of needing an additional gas tank or gas pump, which is inconvenient to carry and has high cost. The power structure of the electric type usually uses compressed spring release to provide power, but the release of compressed spring will inevitably produce a large vibration. This vibration has little effect on the machine itself, but has a great impact on the external components and the sealing components connected to the outside, which may even cause misplacement, liquid leakage, air intake, etc. such as external medicine bottle and needle tube. UTILITY MODEL CONTENTS

[0005] Therefore, in order to solve the above problems, the utility model provides an anti-shake structure of veterinary electric needleless injector to solve the technical defects of misplacement of components with too long force arm and gap caused by high-frequency or high-intensity vibration of the power system of the existing electric needleless injector.

[0006] The utility model is realized by constructing an anti-shake structure of veterinary electric needleless injector, characterized by: the structure includes a shell, a liquid inlet pipe, an anti-shake rubber pad and an external component interface. The liquid inlet pipe is rigidly connected to the internal metal component below and has a sealing rubber ring at the connection. The upper part is rigidly connected to the external component interface. The anti-shake rubber pad is installed in the limiting groove of the shell, and the liquid inlet pipe passes through the hollow anti-shake rubber pad in the middle without directly contacting the shell.

[0007] According to the anti-shake structure of the utility model, the liquid inlet pipe is inserted into the shell and the anti-shake rubber pad obliquely.

[0008] According to the anti-shake structure of the utility model, the liquid inlet pipe is rigidly connected to the internal metal component with a rubber ring.

[0009] This invention offers the following advantages: The anti-shake structure of the proposed veterinary electric needleless injector provides two optimized functions: reducing the risk of detachment when connecting external needles or long vials. When the machine vibrates, the anti-shake rubber ring disperses some of the force through a flexible connection, preventing the external component, acting as a lever arm, from easily detaching. It also effectively prevents the internal waterproof rubber ring from loosening. Because the inlet tube is rigidly connected to the internal metal parts using a rubber ring, if the inlet tube were also rigidly connected to the outer shell, vibration could cause misalignment or leaks at the rubber ring, leading to its failure. Therefore, using a flexible connection between the inlet tube and the outer shell is crucial. Attached Figure Description

[0010] Figure 1 This is a schematic diagram illustrating the implementation of the image stabilization structure of this application.

[0011] The components include: outer shell 1, liquid inlet pipe 2, anti-shake pad 3, and external component interface 4. Detailed Implementation

[0012] The following will be combined with the appendix Figure 1 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0013] This utility model provides an improved anti-vibration structure for an electric needle-free veterinary injector, addressing the technical defects of existing electric needle-free injectors where high-frequency or high-intensity vibrations from the power system cause component misalignment and gaps. For example... Figure 1 As shown, it can be implemented as follows: The anti-shake structure of the electric needleless injector includes a housing 1, an inlet tube 2, an anti-shake pad 3, and an external component interface 4. The specific assembly method is as follows: the lower part of the inlet tube is rigidly connected to other internal metal parts, and the connection is sealed with a rubber ring; the upper part is rigidly connected to the external component interface; the anti-shake pad is installed in the limiting groove of the housing, and the inlet tube passes through the middle of the hollow anti-shake pad without directly contacting the housing.

[0014] Compared with the prior art, the utility model have following beneficial effect: the utility model provides a kind of anti-shake structure of veterinary electric needleless injector, provides two more optimized functions: reduce the risk of falling when external needle tube or long medicine bottle etc.It is dispersed by the flexible connection of this place when the anti-shake rubber ring vibrates in machine itself part of force, so that the external member regarded as force arm will not be easily fallen off.Effectively prevent internal waterproof rubber ring loosening.Because the fixed mode of liquid inlet pipe and internal metal piece is rigid connection containing rubber ring, if liquid inlet pipe is rigidly connected with shell, it is very likely that rubber ring place is dislocated or leaks due to vibration, and then rubber ring is ineffective, so it is very important to use flexible connection between shell.

[0015] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
