Description
Technical Field
The utility model belongs to the technical field of industry gas cylinder processing technique and specifically relates to a throw screw thread protective sheath in gas cylinder.
Background
When the industrial gas cylinder is thrown in, the industrial gas cylinder extends into a steel cylinder through a stainless steel pipe with the diameter of about phi 16, and fine steel shots are sprayed to impact the inner wall of the gas cylinder to clean oxide skin and rust stains, but the steel shots are easy to hit threads of a cylinder opening, so that the tooth tip is damaged or rough, and therefore in order to avoid the situation, the threads of the cylinder opening are protected through a protective sleeve; and can avoid the scratch of the thread when the stainless steel tube enters and exits the steel cylinder.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that the damage to the threads of the bottle opening is easy to occur in the internal casting of the existing gas cylinder, the utility model provides a thread protection sleeve for internal casting of a gas cylinder.
The utility model provides a solve its technical problem's technical scheme is:
a gas cylinder internal thread-throwing protective sleeve, comprising:
the protective sleeve comprises a protective sleeve body, a connecting part and a connecting part, wherein the protective sleeve body comprises an installation part and the connecting part;
the mounting part comprises a first plane and a second plane;
the outer surface of the connecting part is provided with threads.
Further, the first plane and the second plane are parallel.
Furthermore, the connecting part is fixedly connected with the mounting part, and a through hole is formed in the connecting part and the mounting part in a penetrating mode.
Further, the lower end of the through hole is provided with an arc surface part.
Further, the outer diameter of the mounting portion is larger than that of the connecting portion.
Furthermore, an opening part is arranged at the upper end of the through hole, and the inner diameter of the opening part is linearly increased from bottom to top.
The beneficial effects of the utility model are that, through the installation protective sheath for the gas cylinder is when throwing in carrying out, can ensure the complete of bottleneck screw thread. The steel grit used for inner throwing can be simply discharged through the opening part. Through the cambered surface portion that is provided with for the inside steel sand of gas cylinder can not produce at the bottleneck position and pile up, and then makes the protective sheath can not be died by the steel sand lock, and the screw thread damage when having avoided interior throwing improves interior throwing quality.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example 1
As shown in fig. 1, the thread-throwing protective sleeve for the gas cylinder comprises a mounting part 11 and a connecting part 12, wherein the lower surface of the mounting part 11 is fixedly connected with the upper surface of the connecting part 12, a thread 121 is arranged on the outer surface of the connecting part 12, and the thread 121 is used for being in threaded connection with the opening of the gas cylinder. Wherein the external diameter of installation department 11 is greater than the external diameter of connecting portion 12 for connecting portion 12 after covering gas cylinder bottleneck screw thread, can be with protection sleeve body 1 joint, can not enter into inside the gas cylinder completely.
Wherein, installation department 11 and connecting portion 12 all set up to cylindricly, wherein, are provided with first plane 111 and second plane 112 at the side of installation department 11, and wherein first plane 111 and second plane 112 are parallel arrangement, and parallel arrangement makes when using the instrument to rotate protective sheath body 1 more convenient. The first plane 111 and the second plane 112 are only preferred in this embodiment, and optionally, a third plane, a fourth plane, and the like may be further provided, and only the planes that need to be provided can be well matched with a rotating tool such as a wrench, and the like, which can meet the requirements.
Further, a through hole 14 is concentrically penetrated and opened in the mounting part 11 and the connecting part 12, wherein the through hole 14 penetrates through the upper surface of the mounting part 11 and the lower surface of the connecting part 12, and the through hole 14 enables the steel sand in the gas cylinder to be smoothly discharged. Wherein, the upper end of the through hole 14 is provided with an opening part 141, the opening part 141 is in the shape of a circular truncated cone, namely, the inner diameter of the opening part 141 is currently increased from bottom to top, the inner diameter of the bottom end of the opening part 141 is equal to the inner diameter of the through hole 14, and the inner diameter of the upper end of the opening part 141 is smaller than the outer diameter of the mounting part 11. As shown in fig. 1, the angle between the side of the opening 141 and the horizontal plane is preferably 135 ° in the cross-sectional view, so that the steel grit for polishing can be smoothly discharged from the inside of the cylinder along the through hole 14 by the arrangement of the opening 141.
Example 2
On embodiment 1's basis, the internal diameter of through-hole 14 is less than the external diameter of connecting portion 12, the bottom of through-hole 14 is cylindricly, the chamfer is not carried out, promptly this moment because the internal diameter of through-hole 14 is less than the internal diameter of connecting portion 12, connecting portion still have straight face section in the bottom this moment, the existence of this part makes the emery pile up here when leaving the gas cylinder, and then make the emery appear in the threaded connection department of protective sheath body 1 and gas cylinder, also be exactly the emery makes the screw thread lock die, protective sheath body 1 if the compulsory commentaries on classics down this moment, because the wearing and tearing of emery, make gas cylinder bottleneck screw thread necessarily impaired. Therefore, the arc surface part 142 is arranged at the lower end of the through hole 14, and the arc surface part 142 is a smooth curved surface, so that polished steel grit can be discharged along the arc surface part 142 in a smooth transition manner, and the threads of the opening of the gas cylinder are protected from being damaged. The cambered surface design here is the preferred of this embodiment, and the cambered surface portion also can set up to an inclined plane, only need not cause piling up of steel grit in the bottom of connecting portion 12 can, the design of the same effect all falls into the protection scope of this application.
It will be apparent to those skilled in the art that changes and modifications may be made to the present invention without departing from the spirit and scope of the embodiments of the invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
