Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely 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 construed as limiting the invention. Furthermore, the terms "first", "second", etc. 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," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.
In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail below with reference to the drawings and embodiments.
An O-shaped ring assembling tool is shown in figures 1 to 9 and comprises a limiting column 1 and an installation seat 2 sleeved on the limiting column; the mounting seat comprises a guide part 3, an expanding part 4 and a transition part 5 between the guide part and the expanding part, and an avoidance cavity 6, a matching cavity 7 and a transition cavity 8 between the avoidance cavity and the matching cavity are arranged in the mounting seat; the limiting column comprises a working section 9 and a positioning section 10 which is detachably arranged on the working section, the working section and the positioning section are coaxially arranged, and an end cap 11 is arranged at the tail end of the working section; the working section is in sliding fit with the matching cavity, and a positioning surface 12 is arranged at the tail end of the positioning section.
The outer diameter of the end cap is smaller than that of the tail end of the guide part, so that the O-shaped ring is not prevented from being smoothly sleeved into the guide part even when the matching column is inserted into the mounting seat. Typically, the working section outer diameter is greater than the positioning section outer diameter and the end cap outer diameter is greater than the working section outer diameter. The working section is in sliding fit with the matching cavity, the installation seat is guided by the limiting columns (the working section), the structural stability is guaranteed, the installation seat can slide smoothly and fall under the guiding action of the limiting columns, and collision with the external threads of the valve body is avoided.
The surface roughness of the guide portion, the enlarged diameter portion and the transition portion is usually 0.4 μm. The guide part and the transition part as well as the transition part and the diameter expansion part are in smooth transition, so that the O-shaped ring can be smoothly pushed from the guide part to the diameter expansion part and smoothly enters the sealing groove of the valve body. In addition, the free end of the diameter-expanding part is processed with a round-corner structure 13. The free end of the guide part is processed to form a fillet structure, and due to the structural design, the O-shaped ring can be effectively prevented from being scratched.
In an alternative embodiment, the positioning section is provided with a connector 14, the connector is provided with an external thread structure 15, and the working section is provided with a threaded mounting hole matched with the connector. Because location section demountable installation is in the working segment, consequently, can choose suitable location section for use and assemble into spacing post with the working segment according to the specification model of valve body to the different use needs of adaptation, the commonality is good, convenient operation.
The O-shaped ring assembling tool provided by the invention is simple in structure and convenient to use and operate, when the O-shaped ring is installed on the valve body installation part, only the O-shaped ring 18 is sleeved on the installation seat (the operation that the limiting column is inserted in the installation seat can be performed before the O-shaped ring is sleeved on the installation seat or after the O-shaped ring is sleeved on the installation seat), then one side of the positioning section of the limiting column is inserted into the valve body to abut against the step of the inner cavity of the valve body, then the installation seat is axially slid along the limiting column, so that the installation seat is sleeved on the connecting end 17 of the valve body 16, the installation seat cannot collide with the external thread of the valve body under the guiding of the limiting column, and when the installation seat is in place, the O-shaped ring is pushed downwards to fall into the sealing groove 19 of the valve body installation part after passing through the transition part and the diameter expansion part.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
