Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, a leak protection pneumatic cover comprises a cap 1 and a sleeve 2, a baffle 21 is arranged in the middle of the sleeve 2, one end of the sleeve 2 is movably connected with the cap 1, the other end of the sleeve 2 is inserted into a tube head 3, one end of the sleeve 2 connected with the tube head 3 is provided with a plurality of notches 22, one end of the cap 1 is provided with a spring 11 and a plug 12, one end of the spring 11 is connected with the cap 1, the other end of the spring 11 is connected with the plug 12, the plug 12 is installed in the sleeve 2, a mounting plate 13 is further arranged on one side, adjacent to the sleeve 2, of the cap 1, and a bolt penetrates through the mounting plate 13 and the baffle 21 is connected with the tube head 3. Specifically, in this embodiment, when the cannula 2 is used, the cannula 2 is inserted into the ferrule 3 first, and the stopper 21 in the middle of the cannula 2 abuts against the ferrule 3, so that the cannula 2 is prevented from falling into the ferrule 3 and being taken out. In order to insert the sleeve 2 into the tube head 3, one end of the sleeve 2 connected with the tube head 3 is provided with a plurality of notches 22, so that the strength of the end part of the sleeve 2 is reduced, one end of the sleeve 2 with the notches 22 can be compressed and is inserted into the tube head 3 in a matching manner to be tightly abutted against the inner wall of the tube head 3, the gap is small, and the air tightness is good. Further, a spring 11 and a plug 12 are arranged in the cap 1, when the cap 1 is covered on the sleeve 2, the plug 12 is installed in the sleeve 2, and the plug 12 and the cap 1 simultaneously plug the sleeve 2 to prevent gas in the pipe head 3 from leaking out. When the air pressure in the pipe head 3 rises, the spring 11 is compressed, so that the internal volume of the pipe head 3 is increased, and the air pressure is reduced; when the air pressure in the tube head 3 reduces, the spring 11 recovers naturally, the volume in the tube head 3 reduces, the air pressure rises, the spring 11 is matched with the plug 12, the gas is prevented from directly impacting the cap 1, the phenomenon that the cap 1 is cracked after being used for a long time is avoided, and the service life of the cap is effectively prolonged.
