Abstract

The utility model relates to a connecting piece technical field discloses a tubular connecting piece, tubular connecting piece includes top tube and low tube, the lower tip of top tube dwindles the pipe diameter, and the surface of the lower tip of top tube is formed with the trapezoidal thread in order to push sunken processing mode, be formed with two interior bumps on the internal face of the upper end part of low tube, two interior bumps are not on same horizontal plane, two interior bumps are underlaped at the projective point of horizontal plane, and perpendicular distance between two interior bumps does the half of the pitch of trapezoidal thread, when the low tube two interior bumps with the top tube during the trapezoidal thread interlock, the internal face of the upper end of low tube part with the surface in close contact with of the lower tip of top tube. This tubular connecting piece's dismouting is gone on very conveniently.

Description

A kind of tubular type web member

Technical field

The utility model relates to web member technical field, particularly relates to a kind of tubular type web member.

Background technology

At present, web members many on market is all made up of screw and nut, finds in practice, these web members be assembling or dismounting, usually all need by such as spanner, etc. external tool, all bring very big inconvenience to user.

Practical novel content

The utility model discloses a kind of tubular type web member, the dismounting of this tubular type web member is very convenient.

A kind of tubular type web member, described tubular type web member comprises top tube and down tube, and the end portion of described upper pipe reduces caliber, and the outside surface of the end portion of described upper pipe is formed with trapezoidal thread to extrude the processing mode of depression; The inner-wall surface of the upper end portion of described lower pipe is formed two convex points, described two convex points are not on same horizontal plane, described two convex points are not overlapping at the subpoint of horizontal plane, and the vertical range between described two convex points be described trapezoidal thread pitch 1/2nd; When described two convex points of described lower pipe are engaged with the described trapezoidal thread of described upper pipe, the inner-wall surface of the upper end portion of described lower pipe contacts with the intimate of the end portion of described upper pipe.

Tubular type web member according to claim 1, it is characterised in that, described upper pipe and described lower pipe are plastic cement pipe or metal tube.

Compared with prior art, the utility model has following useful effect:

In the utility model, the upper pipe that the outside surface of end portion is formed with trapezoidal thread to extrude the processing mode of depression is equivalent to screw, and the inner-wall surface of upper end portion is formed two convex points and is equivalent to nut, instantly when two convex points of pipe are engaged with the trapezoidal thread of upper pipe, the inner-wall surface of the upper end portion of lower pipe contacts with the intimate of the end portion of upper pipe, such that it is able to realize the firm docking of top tube and down tube. Tubular type web member disclosed in the utility model is without the need to realizing connecting by external tool or the other junctor that increases, and easy accessibility, is connected firmly, effectively reduces production cost.

Accompanying drawing explanation

In order to the technical scheme being illustrated more clearly in the utility model embodiment, it is briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only practical novel part embodiment, instead of whole embodiments. Based on practicality novel in embodiment, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of utility model protection.

The utility model discloses a kind of tubular type web member, the dismounting of this tubular type web member is very convenient. Hereinafter it is described in detail respectively.

Seeing also Fig. 1��Fig. 4, Fig. 1 is the structure iron of the upper pipe of a kind of tubular type web member disclosed in the utility model embodiment; Fig. 2 is the structure iron of the lower pipe of a kind of tubular type web member disclosed in the utility model embodiment; Fig. 3 is the assembling process schematic diagram of a kind of tubular type web member disclosed in the utility model embodiment; And Fig. 4 is the structure iron of a kind of tubular type web member disclosed in the utility model embodiment. As shown in Figure 1 to 4, this tubular type web member comprises:

Top tube and down tube, the end portion of described upper pipe reduces caliber, and the outside surface of the end portion of described upper pipe is formed with trapezoidal thread a (as shown in Figure 1) to extrude the processing mode of depression; The inner-wall surface of the upper end portion of described lower pipe is formed two convex point b, described two convex points are not on same horizontal plane, described two convex points are not overlapping at the subpoint of horizontal plane, and the vertical range between described two convex points is 1/2nd (as shown in Figure 2) of pitch of described trapezoidal thread; When described two convex points of described lower pipe are engaged with the described trapezoidal thread of described upper pipe, the inner-wall surface of the upper end portion of described lower pipe contacts with the intimate of the end portion of described upper pipe.

It is plastic cement pipe or metal tube as a kind of enforcement mode preferentially, described upper pipe and described lower pipe.

In the utility model, the assembling mode of this tubular type web member can be as shown in Figure 3, first fixing good described lower pipe, (it is inserted into upper pipe described herein can not down insert again) when described upper pipe is inserted into first convex point point of described lower pipe and it is screwed in the way of being rotated down, until terminating when the inner-wall surface of the upper end portion of described lower pipe contacts tighten with the intimate of the end portion of described upper pipe, what it was complete be assembled into up and down pipe compact siro spinning technology together, non-loosening, obscission.

Being described in detail by tubular type web member disclosed in the utility model embodiment above, apply specific case herein and principle of the present utility model and enforcement mode have been set forth, the explanation of above embodiment just understands the utility model for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.

Claims

1. a tubular type web member, it is characterised in that, described tubular type web member comprises top tube and down tube, and the end portion of described upper pipe reduces caliber, and the outside surface of the end portion of described upper pipe is formed with trapezoidal thread to extrude the processing mode of depression; The inner-wall surface of the upper end portion of described lower pipe is formed two convex points, described two convex points are not on same horizontal plane, described two convex points are not overlapping at the subpoint of horizontal plane, and the vertical range between described two convex points be described trapezoidal thread pitch 1/2nd; When described two convex points of described lower pipe are engaged with the described trapezoidal thread of described upper pipe, the inner-wall surface of the upper end portion of described lower pipe contacts with the intimate of the end portion of described upper pipe.
