Description
Technical field
The utility model relates to mechanical fastener field, particularly relates to a kind of connection protective gear for jointing and pipe.
Background technique
Pipe, particularly urea tube, before use, be adopt joint and pipe directly to press-fit in most cases, then bellows protected by suit again, and last bellows is fixed together by insulating tape and joint.Figure 1 shows that a typical joint connection manner, wherein, joint A first press-fits with pipe, press-fits rear sheathed protection bellows B, is linked together by sheathed protection bellows B and joint A finally by insulating tape C.
But this Connecting format of prior art can bring following problem:
1, when exposed to external forces, because insulating tape effectively can not resist external force, therefore bellows and joint junction there will be the situation of easy forced breakage;
2, bellows and joint adopt insulating tape to be wound around, with the passing of time adhesive tape problem of aging can be produced, thus easily come off, the adhesive tape come off likely to be wound around on other pipe and to affect the use of other pipes, if adhesive tape comes off, bellows and joint will be caused to depart from, expose interior pipe, may wear and tear with other pipelines, bellows also just loses de-protected effect;
3, adopt insulating tape to be wound around, adhesive tape can be there is and depart from, affect integrity.
Model utility content
The purpose of this utility model is to provide a kind of connection protective gear for jointing and pipe, can resist external force, prevent wearing and tearing and improve integrity.
A kind of connection protective gear for jointing and pipe that the utility model provides; comprise housing; described enclosure interior is formed with hollow portion; the shape of cross section of described hollow portion is circular, in described hollow portion, be formed with joint fixing part and bellows fixing part respectively along the axial direction of described hollow portion.
Further, in described hollow portion, be also formed with ring fixing part, described ring fixed position is between the described joint fixing part and bellows fixing part of the axial direction along described hollow portion.
Further, the floor that described joint fixing part, ring fixing part and bellows fixing part are radially extended internally by the inwall from described hollow portion is respectively formed.
Further, described housing comprises the first housing and the second housing, and is connected by the loose-leaf portion between the first housing and the second housing.
Further, described first and second housings are symmetrical arranged relative to described loose-leaf portion.
Further, described first and second housings include the engagement portion for being fixed together by described first and second housings.
Further, the axis being provided with the hollow portion of described joint fixing part overlaps mutually with the axis of the hollow portion being provided with described bellows fixing part or vertical.
Further, described pipe is urea tube, and described joint is urea tube joint.
By above technological scheme, achieve following object:
1, adopt connection protective gear of the present utility model, when exposed to external forces, the housing connecting protective gear effectively can resist external force to a certain extent, therefore serves the effect of protection bellows and joint junction, makes its not easily forced breakage;
2, abandoned traditional adhesive tape to be intertwined and connected, and directly connected by arranging connection housing, avoided bellows and joint disengaging on the one hand, and also avoid pipe in work to be worn and to disturb;
3, adopt connection protective housing, add integrity, therefore can not there is adhesive tape and depart from.

Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Figure 2 shows that connection set first embodiment schematic diagram of the present utility model.In the present embodiment, described pipe is urea tube, and described joint is urea tube joint.But, in the middle of practical application, be not limited to pipe and the structure of above type.
As shown in Figure 2; connection protective gear in the present embodiment comprises housing 1; hollow portion is formed in housing 1 inside; in order to adapt to the shape of joint and bellows; this hollow portion cross section is circular; in this hollow portion, be formed with joint fixing part 4 and bellows fixing part 6 respectively, be respectively used to permanent joint and bellows.Particularly, in order to the stability keeping joint fixing better, between the described joint fixing part and bellows fixing part of the axial direction along described hollow portion, ring fixing part 5 is formed with.The floor that above-mentioned joint fixing part 4, ring fixing part 5 and bellows fixing part 6 are radially extended internally by the inwall from described hollow portion is respectively formed.
As shown in Figure 2; the housing 1 of above-mentioned connection protective gear is divided into the first housing 1a and the second housing 1b; first housing 1a and the second housing 1b adopt a loose-leaf portion 2 to be connected; certainly; the first housing 1a in the utility model and the second housing 1b are also not limited to be connected by loose-leaf portion; also can be do not adopt each other to connect in any way, such as the first housing 1a and the second housing 1b be split type.Further, the first housing 1a and the second housing 1b is split type can be symmetrical arranged, and can be asymmetric setting.Meanwhile, fixing in order to after combining, described first housing 1a and the second housing 1b include for the engagement portion 3 together with being fixed by described first and second housings.
Fig. 3 is the link position schematic diagram of connection set first embodiment middle joint of the present utility model.As shown in Figure 3; joint A is now placed in one of them housing of described connection protective gear; in this embodiment; joint fixing part 4 is set to two; it engages with two joining portion 4 ' on described joint A respectively; adopt and can ensure that joint can not swing back and forth in connection set in this way, ensure that balance.The ring portion A1 of joint A is just in time positioned at described ring fixing part 5 place, and at the outer socket pipe of ring portion A1 and overcoat bellows, after being merged by a housing 1a and the second housing 1b, ring fixing part 5 just can fix the attachment portion of joint herein and pipe.
