The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0020] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, a small-aperture perforator housing structure is provided, wherein the structure of the small-aperture perforator housing structure is as follows: Figure 1 As shown, the small-aperture perforator housing structure includes multiple spliced ​​tubular bodies 10, the structure of which is as follows: Figure 1As shown. It is worth noting that each of the pipe fitting bodies 10 has an opening 103 and a cavity 101. The opening 103 communicates with the outside and the cavity 101 respectively, forming the cavity 101. A threaded groove 102 is also provided on the wall surface near the opening 103, and the threaded groove 102 is spaced a predetermined distance from the opening 103. It should be noted that the end of the pipe fitting body 10 away from the threaded groove 102 also has an insertion part 11. The insertion part 11 is configured to pass through the opening 103 and be placed inside the cavity 101. The insertion part 11 placed in the cavity 101 cooperates with the threaded groove 102, so that the insertion part 11 can be rotated to continuously move away from the opening 103. It should be noted that the above-mentioned pipe fitting body 10 has a small-sized pipe fitting structure, and because the threaded groove 102 is provided at the cavity 101, and this threaded groove 102 is also near the opening 103, Furthermore, during actual installation, if the depth of the insertion part 11 is too great, the thin-walled portion of the pipe body 10 may deform and crack due to the machining accuracy issues of the thin-walled parts. Therefore, this application provides a solution to avoid the aforementioned problem.

[0021] Specifically, a positioning groove 104 is formed on the wall of the cavity 101. The positioning groove 104 has an arc-shaped structure and is located at the opening 103. The end of the positioning groove 104 is also connected to the outside.

[0022] Furthermore, the small-aperture perforator housing structure also includes a pressure block 20, which is bonded to the sidewall forming the positioning groove 104, and its installation position is as follows: Figure 2 As shown, the pressure block 20 is implemented as a rubber component.

[0023] Furthermore, each of the pipe fitting bodies 10 has a first positioning hole 105, the two ends of which are respectively connected to the outside and the positioning groove 104.

[0024] Furthermore, the small-aperture perforator housing structure also includes a collar assembly 30, which is disposed on the insertion part 11. When the insertion part 11 moves away from the opening 103, the collar assembly 30 abuts against the bottom of the pressure block 20 to limit the tooth depth of the insertion part 11.

[0025] Specifically, the insertion part 11 has a first annular groove 1101, and the collar assembly 30 further includes a movable ring 31, which is movably disposed on the first annular groove 1101. Notably, the movable ring 31 is implemented as a rubber part, allowing it to be mounted on the first annular groove 1101 by compression deformation. The outer wall of the movable ring 31 also has a second annular groove 3101. Furthermore, the small-diameter perforator housing structure includes a positioning ring 32, which is disposed on the second annular groove 3101. Specifically, one end of the second annular groove 3101 communicates with the outside, facilitating the mounting of the positioning ring 32 on the second annular groove 3101. When the insertion part 11 moves away from the outlet 103, the side wall of the positioning ring 32 directly contacts the pressure block 20, preventing the insertion part 11 from moving and thus limiting its position.

[0026] It should also be noted that the outer wall of the positioning ring 32 has a plurality of spaced positioning holes 3201. The first positioning hole 105 can correspond to one of the positioning holes 3201. The small-diameter perforator housing structure also includes an insert 40. One end of the insert 40 passes through the first positioning hole 105 and is located inside the positioning hole 3201, while the other end is located outside or inside the positioning hole 3201. The insert 40 serves as an indicator to show that the part is installed correctly, providing conditions for subsequent visual inspection and thus avoiding the problem of missing parts.

[0027] In summary, the small-aperture perforator housing structure described in the embodiments of this application has been clarified, which provides advantages such as ease of use, low cost, and good safety for the small-aperture perforator housing structure.

[0028] It is worth mentioning that, in the embodiments of this application, the small-aperture perforator housing structure is simple in structure, does not involve complex manufacturing processes or expensive materials, and has high economic efficiency. At the same time, for manufacturers, the small-aperture perforator housing structure provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
