Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 3, in the present embodiment, a fracture-type extraction tube includes a tube body 1 having a tube cavity 11 and a tube cap, wherein the tube cap includes a cap body 2 and a tube head 3 which are integrally formed, and the tube head 3 and the cap body 2 are separated from each other by fracture. The pipe body 1 is preset with external screw teeth 12 and a plurality of auxiliary lugs 42, wherein the external screw teeth 12 are arranged on the upper edge of the pipe body 1; a plurality of auxiliary protrusions 42 are annularly arranged on the outer wall of the pipe body 1. The cover body 2 is formed with an inner ring 21 and an outer ring 22, wherein a groove 23 is formed between the inner ring 21 and the outer ring 22. The inner ring 21 is predisposed with a sealing portion 211 shaped in the form of a ring. The outer ring 22 is provided with internal threads 221, a liquid outlet 24 and a plurality of vertical threads 41 in advance, wherein the liquid outlet 24 is arranged at the top of the outer ring 22, and when the tube head 3 is not broken and separated from the cover body 2, the tube head 3 blocks the liquid outlet 24. A plurality of vertical lines 41 are annularly arranged on the outer wall of the outer ring 22.

Referring to fig. 4, in the present embodiment, the pipe body 1 or the pipe cover is screwed to screw the inner threads 221 and the outer threads 12, so that the pipe cover and the pipe body 1 are fixedly installed and connected to each other. In the process of matching the inner threads 221 with the outer threads 12, the inner ring 21 is embedded into the tube cavity 11, so that the sealing part 211 and the tube cavity 11 are mutually sealed and attached to form a first layer of seal of the extraction tube, and meanwhile, the upper edge of the tube body 1 is embedded into the groove 23. When the pipe cover and the pipe body 1 are installed, the top of the pipe body 1 and the top of the groove 23 are mutually sealed and attached to form a second layer of seal of the extraction pipe, so that the extraction pipe has better sealing performance. When the tube cover is screwed, friction is increased through the vertical grains 41, so that the tube cover is easier to screw; when screwing the tube body 1, the tube body 1 is screwed more easily through the auxiliary lug 42, so that the possibility of breaking and separating between the tube head 3 and the cover body 2 in the installation process is reduced, and the abnormal use of the extraction tube caused by the premature breaking and separating between the tube head 3 and the cover body 2 is avoided.

In the present embodiment, the end of the tube body 1 away from the tube cover is made of soft material, such as soft plastic, soft rubber, silicone rubber, etc. When the extraction tube is used, the extraction tube filled with liquid is turned over, the tube head 3 faces downwards, the tube head 3 is broken off and separated from the cover body 2, so that the liquid in the extraction tube can be dripped out from the liquid outlet 24, and further, the tube body 1 is extruded, so that the liquid is dripped out, and liquid extraction is realized.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents to the embodiments of the utility model without departing from the scope of the utility model as set forth in the claims below. Therefore, equivalent changes made according to the spirit of the present invention should be covered within the protection scope of the present invention without departing from the contents of the technical scheme of the present invention.
