It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the 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 be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to fig. 3, the waterproof connecting mechanism of the present invention will now be described. The waterproof connecting mechanism comprises a first cylinder body 1 with external threads (cylinder body: tubular object with through-hole, optionally, in one embodiment, the cylinder body is a cylinder; specifically, in one embodiment, the axis of the cylinder is a straight line) and a second cylinder body 2 with internal threads; the first cylinder 1 and the second cylinder 2 are in threaded connection and are communicated with each other; an annular groove 21 is formed in the inner wall of the second cylinder 2, and a sealing ring 3 is arranged in the annular groove 21; when the external thread of the first cylinder 1 is matched with the internal thread of the second cylinder 2 and screwed into a preset position in the second cylinder 2, the sealing ring 3 is sleeved on the first cylinder 1.

Therefore, the first cylinder 1 and the second cylinder 2 are in threaded connection to realize mutual fixation/mutual separation, and the first cylinder 1 and the second cylinder 2 are communicated with each other for a lead to pass through; an annular groove 21 is formed in the inner wall of the second cylinder 2, and a sealing ring 3 is arranged in the annular groove 21; when the first cylinder body 1 is screwed into the second cylinder body 2 to a preset position, the sealing ring 3 is sleeved on the first cylinder body 1, so that the sealing ring 3 seals a gap between the outer wall of the first cylinder body 1 and the inner wall of the second cylinder body 2, and leakage in the gap between the first cylinder body 1 and the second cylinder body 2 is avoided.

Further, referring to fig. 1 to 3, as an embodiment of the waterproof connecting mechanism of the present invention, the cross section of the sealing ring 3 is circular. In this way, the circular sealing ring 3 is easy to produce and install.

Further, referring to fig. 1 to 3, as an embodiment of the waterproof connecting mechanism of the present invention, the cross section of the annular groove 21 is rectangular. Thus, the rectangular groove is easily processed.

Further, referring to fig. 1 to 3, as an embodiment of the waterproof connecting mechanism of the present invention, an annular groove 21 is adjacent to the internal thread. In this way, when the first cylinder 1 is screwed into the second cylinder 2, the annular groove 21 is reached as soon as the first cylinder 1 passes over (over: the first cylinder 1 partially/completely passes over) the internal thread, so that the sealing ring 3 in the annular groove 21 can be fitted over the first cylinder 1 at the first time.

Further, referring to fig. 1 to 3, as a specific embodiment of the waterproof connecting mechanism of the present invention, the sealing ring 3 is an integrated member made of silica gel. Thus, the silica gel has good elasticity and wear resistance.

Further, referring to fig. 1 to 3, as an embodiment of the waterproof connecting mechanism of the present invention, a side wall of the annular groove 21 is perpendicular to an axial direction of the sealing ring 3. So, sealing ring 3 contacts with first barrel 1 and establishes the in-process on first barrel 1 at the cover, and sealing ring 3 receives the ascending thrust of sealing ring 3 axis direction easily, and the inner wall of ring channel 21 is perpendicular with the axis direction of sealing ring 3 for above-mentioned thrust can effectively be offset off to ring channel 21 inner wall so that sealing ring 3 is difficult to roll off ring channel 21.

Further, referring to fig. 1 to 3, as a specific embodiment of the waterproof connecting mechanism of the present invention, in the screwing direction of the first cylinder 1, the surface of the first cylinder 1 in front of the external thread is a cylindrical surface. So, when first barrel 1 screw in second barrel 2, the face of cylinder in external screw thread the place ahead contacts with sealing ring 3 in the second barrel 2 at first, and sealing ring 3 is better with the sealed effect of the face of cylinder contact of the aforesaid, is difficult to produce the clearance between sealing ring 3 and first barrel 1.

Further, referring to fig. 1 to 3, as a specific embodiment of the waterproof connecting mechanism of the present invention, a protruding portion 22 is formed on the inner wall of the second cylinder 2; the boss 22 is located downstream of the internal thread in the screwing direction of the first cylinder 1. Thus, when the first cylinder 1 is screwed into the second cylinder 2 and passes over (over: the first cylinder 1 partially/completely passes over) the internal thread, the boss 22 can limit the first cylinder 1, and prevent the first cylinder 1 from being screwed too much.

Further, referring to fig. 1 to 3, as an embodiment of the waterproof connecting mechanism of the present invention, a surface of the protruding portion 22 facing the internal thread is a plane. In this way, when the first cylinder 1 passes over (over: the first cylinder 1 partially/completely passes over) the internal thread and contacts the projection 22, the surface of the projection 22, which is flat, contacts the first cylinder 1, and thus the first cylinder 1 is not easily scratched.

Further, referring to fig. 1 to 3, as a specific embodiment of the waterproof connecting mechanism of the present invention, the protruding portion 22 is a protruding ring annularly disposed on the inner wall of the second cylinder 2. Therefore, the convex ring annularly arranged on the inner wall of the second cylinder body 2 can block the first cylinder body 1 from any position of the circumferential direction of the inner cavity of the second cylinder body 2.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
