Abstract

The utility model belongs to a casing positioning and connecting device of tubes in daily-use articles or mechanical engineering. The tube wall of a tube 4 on the main tube end is punched with an elastic member (42). The shape of the elastic member (42) forms a bow shape convex to an inner wall. A pressing surface (42) in the elastic member (42) is parallel and close to the tube wall to form good elastically buckling function to position and connect two tubes to be sheathed by casing. The casing positioning and connecting device of tubes has the advantages of stable casing positioning, easy fabrication and low cost.

Description

Pipe pipe box positioning connecting device

The utility model belongs to a kind of pipe pipe box connection set in mechanical engineering or the daily necessities.

Known pipe pipe box position structure, common has two kinds, for narrate clear for the purpose of, earlier that these two kinds known pipe pipe box position structure description of drawings are as follows:

Fig. 1 is that simple pipe pipe box connects three-dimensional structure diagram.

Fig. 2 is the pipe pipe box of the band U type elastic component three-dimensional structure diagram that is located by connecting.

Fig. 3 is be located by connecting a cut-away view behind the suit of the pipe pipe box of band U type elastic component.

The pipe 2--that 1--is shaped on female pipe end is shaped on the pipe of public pipe end

11--has the female pipe end with calibers such as public pipe end shrink mouths

21--has the public pipe end 22--U type elastic component of less reducing external diameter

The rectangular through-hole of offering on public pipe end 21 tube walls of 211--

The projection that matches with rectangular through-hole 211 on the 221--U type elastic material

As shown in Figure 1, known simple pipe pipe box position structure, form by two two pipes 1 and 2 of planning pipe box, be shaped on the public pipe end 21 of less reducing external diameter at an end of pipe 2, be shaped on female pipe end 11 with calibers such as public pipe end shrink mouths at an end of pipe 1, when pipe box connects, by public pipe end 21 corresponding female pipe end 11 pipe box plug-in mountings, because between the external diameter of the internal diameter of its female pipe end 11 and public pipe end 21 the certain clearance gap is arranged during design, loosening state pipe box plug-in mounting, this pipe box plug-in mounting, easy to be laborsaving.But also be subjected to easily to throw off after the external force effect and drop, in a word, this pipe box plug-in mounting, its radial location is bad, so steadiness is not good enough, comes off easily, and promptly it has the effect of pipe box plug-in mounting, but lacks locating effect.

Again as can be known by Fig. 2 and Fig. 3, the pipe box of known band U type elastic component is located by connecting, promptly on simple pipe pipe box connection basis, on the tube wall of public pipe end 21, offer a rectangular through-hole 211, and U type elastic component 22 is installed, special projection 221 that is complementary with rectangular through-hole on this U type elastic component 22 in pipe.By means of the elastic top of U type elastic component 220 usefulness instead, during with female pipe end 11 pipe box plug-in mountings, reach positioning action at public pipe end 21, this pipe box is located by connecting structurally more loaded down with trivial details, cost height, waste of manpower during installation, waste man-hour.

The purpose of this utility model is to connect at known simple pipe sleeve pipe that structurally steadiness is bad, the shortcoming that comes off easily.And the pipe pipe box of band U type elastic component 220 is located by connecting, structurally more loaded down with trivial details, the cost height, expense manpower, the drawback when taking a lot of work during installation, on the basis that known simple tubulose property management cover is located by connecting, a kind of pipe pipe box positioning connecting device of novelty is provided, it is simple in structure, easily manufactured that it is had, can pipe box firm, can reach locating effect again.

Realization of the present utility model is on the basis of known tubulose property management cover junctor structure, in addition architecture advances.Design intends carrying out two pipes of pipe box, one is shaped on public pipe end pipe, one has female pipe end pipe, on the tube wall of female pipe end pipe, be shaped on an elastic component, the shape of this elastic component is the bow bodily form to the inwall projection, promptly be parallel and slightly protrude from the face that compresses of female pipe end pipe inwall with the tube wall inboard, and two end elastic arm of tilting and extending internally and to be connected with the tube wall one, the elastic arm that compresses face two ends is connected with tube wall, compresses face two sides and the separated formation elasticity of tube wall hole.

When pipe box connects,,, produce and compress locating function, so that reach the purpose that pipe box is located by connecting by means of the elastic force effect of this elastic material by the corresponding female pipe end pipe pipe box plug-in mounting of public pipe end pipe.

Below in conjunction with description of drawings and embodiment the utility model structure is further described:

Description of drawings:

Fig. 4 is the utility model three-dimensional structure diagram.

Fig. 5 is the sectional view behind the utility model pipe box.

Fig. 6 is the stereo amplification figure of the utility model elastic component.

The pipe 4--that 3--is shaped on public pipe end is shaped on the pipe of female pipe end

31--has the public pipe end of less reducing external diameter

41--has the female pipe end with calibers such as public pipe end shrink mouths

42--elastic component 421--compresses face

422--elastic arm 425--elasticity hole

As shown in Figure 4 and Figure 5, adopt metal matter pipe, make two can pipe box pipe, promptly make the pipe 3 of public pipe end 31 and pipe 4 inside elastic component 42 of punching out on the tube wall of the pipe 4 of female pipe end 41 of female pipe end 41, the shape of this elastic component 42 is the bow bodily forms to the inwall projection, promptly be parallel and slightly protrude from the face that compresses 421 of female pipe end 41 pipes 4 inwalls with the tube wall inboard, and two end elastic arm 422 of tilting and extending internally and to be connected with the tube wall one, promptly this elastic arm 422 that compresses two ends of face 421 is connected with tube wall, compresses face two sides then and thrust between tube wall and form elasticity hole 425.

When the pipe box plug-in mounting, to there be female pipe end 41 of the pipe 3 corresponding pipes 4 of public pipe end 31 to be inserted in, public pipe end 31 inside sleeves, when arriving elastic component 42 positions in advancing, because the elastic reaction of elastic component 42, guiding enters female pipe end 4 easily along with the inclination of one end elastic arm 422, because the effect roof pressure elastic component 42 that this part caliber changes expands outwardly, make its elastic arm 422 produce the counteractive active force that compresses relatively, owing to compressing face 421, it is to be parastate, compresses that it is firm to reach the pipe box location again so can be the closely connected of a plane with public pipe end 31 with tube wall, plug-in mounting is convenient, make simply the purpose that cost is low.

The utility model also is applicable to plastics matter pipe, carries out pipe box and is located by connecting, and when making elastic component 42, should slightly heat on the technology again and suppress with mould.

The utility model pipe pipe box is located by connecting and is widely used in mechanical engineering and the daily living article, as the combined string of support frame in the plastics wardrobe, the support frame of sunshade account etc.
