Abstract
The utility model discloses a kind of threaded flat head, comprise base plate, side frame and outward edge, the lower end of this side frame is fixedly connected with described base plate, the upper end of this side frame is fixedly connected with described outward edge, its innovative point is: the inwall of this side frame is provided with internal thread, and described side frame is upper end diameter is greater than the tapered sleeve cylinder of lower end diameter.The utility model, by arranging internal thread on the inwall of flat head, is threaded connection when making it be connected with container or pressure piping, avoids the phenomenon that flat head can not be lost; When side frame adopts tapered sleeve barrel structure to coordinate with assembly parts in addition, compared to straight sleeve, add matching surface, thus increase the keying strength of end socket.
Description
Technical field
The utility model relates to a kind of flat head, particularly relates to a kind of threaded flat head.
Background technique
Flat head also claims flat bottom cover, be divided into by profile: flat punching end socket, flat tube sheet end socket, flanging flat head and flat bottom cover are usually used in large pressurized vessel and pressure piping, current flat head is all directly mount cover on the port of container or pressure piping, the high pressure occasion of peak period and frequent starting is run at large pressurized vessel and pressure piping, it mounts cover instability, easy loss, thus occur to lose heart rapidly and cause certain property loss and personal safety because end socket flies out at a high speed.
Model utility content
The purpose of this utility model is just to provide a kind of threaded flat head to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of threaded flat head, comprise base plate, side frame and outward edge, the lower end of this side frame is fixedly connected with described base plate, the upper end of this side frame is fixedly connected with described outward edge, its innovative point is: the inwall of this side frame is provided with internal thread, and described side frame is upper end diameter is greater than the tapered sleeve cylinder of lower end diameter.
Further, described tapered sleeve cylinder upper end diameter is 6 ~ 8:4 ~ 5 with the diameter ratio of lower end diameter.
Further, described tapered sleeve cylinder upper end diameter and the preferred diameter of lower end diameter are than being 7:5.
Further, described internal thread is circle-arc screw-thread or V thread screw.
Further, described outward edge and described base plate are parallel to each other.
The beneficial effects of the utility model are:
The utility model, by arranging internal thread on the inwall of flat head, is threaded connection when making it be connected with container or pressure piping, avoids the phenomenon that flat head can not be lost; When side frame adopts tapered sleeve barrel structure to coordinate with assembly parts in addition, compared to straight sleeve, add matching surface, thus increase the keying strength of end socket.
This tapered sleeve cylinder adopts aforementioned proportion, thus the join strength of maximized guarantee end socket and self-strength, therefore the utility model has reasonable in design and that working life is longer advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of threaded flat head described in the utility model;
Fig. 2 is A-A sectional view in Fig. 1.
In figure: 1-base plate, 2-side frame, 3-outward edge, 4-internal thread.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of threaded flat head, comprise base plate 1, side frame 2 and outward edge 3, the lower end of this side frame 2 is fixedly connected with base plate 1, and the upper end of this side frame 2 is fixedly connected with outward edge 3.In order to ensure keying strength, the inwall of this side frame 2 is provided with internal thread 4, and side frame 2 is greater than the tapered sleeve cylinder of lower end diameter for upper end diameter.
In order to ensure that the self-strength of end socket can not decrease because of tapered sleeve barrel structure, tapered sleeve cylinder upper end diameter and the diameter ratio of lower end diameter are 6 ~ 8:4 ~ 5, and another tapered sleeve cylinder upper end diameter is 7:5 with the preferred diameter ratio of lower end diameter.
Above-mentioned internal thread 4 is circle-arc screw-thread or V thread screw, because of when ensureing the join strength of circle-arc screw-thread or V thread screw, circle-arc screw-thread or V thread screw are relatively little to weakening tapered sleeve cylinder self-strength, thus maximize the join strength improving end socket.
For the ease of later stage assembling, outward edge 3 and base plate 1 are parallel to each other.
By arranging internal thread on the inwall of flat head, being threaded connection when making it be connected with container or pressure piping, avoiding the phenomenon that flat head can not be lost; When side frame adopts tapered sleeve barrel structure to coordinate with assembly parts in addition, compared to straight sleeve, add matching surface, thus increase the keying strength of end socket.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are done, is all contained within interest field of the present utility model.
Claims (5)
