Abstract
The utility model relates to a pipe connecting piece, in particular to a bellow joint. The bellow joint comprises a hollow joint body and a locking cover, wherein the joint body is orderly provided with a clamping portion, a connecting portion and a fixed portion from top to bottom, the locking cover is provided with a through hole, a bellow passes through the through hole, the locking cover and the connecting portion are connected by adopting threads, the clamping portion comprises a plurality of clamping blocks, the clamping blocks are equidistantly arranged on the upper edge of the connecting portion, the locking cover is provided with an inclined plane which drives the clamping blocks to be held toward the middle portion, a positioning pipe which is arranged in a hollow mode is further arranged in the connecting portion, and the upper edge of the positioning pipe is higher than the top portions of the clamping blocks. The positioning pipe can be used to sleeve bellows, and plays the role of positioning, the clamping blocks and the positioning pipe play the role of clamping the bellows when the clamping blocks are closely held, and the bellow joint effectively prevents the situation that the bellows are softened to break away from the bellow joint from happening.
Description
Technical field
The utility model relates to a kind of tube connection piece, refers to a kind of corrugated pipe connector especially.
Background technique
Existing corrugated pipe connector comprises joint body and the tightening cover that hollow arranges, this joint body is disposed with inserted part, joint and fixing part from top to bottom, tightening cover is provided with the through hole that passes for bellows, tightening cover adopts with joint and is threaded, the inserted part comprises some clamping blocks, this clamping block equidistantly is arranged on the top edge of joint, and tightening cover is provided with and drives the inclined-plane that clamping block is held tightly to the centre; This structure is when connecting bellows, bellows passes the through hole on the tightening cover earlier, pass the inserted part again and put into joint, place in the joint until the bottom of bellows, tightening cover is connected with joint again, hold tightly to the centre at the top that drives clamping block, until the locking work of finishing bellows, when but the structure of this corrugated pipe connector was longer between in use, because bellows is softening, bellows very easily broke away from this corrugated pipe connector; And the top of clamping block is more smooth, causes bellows under not softening situation, and bellows also very easily breaks away from this corrugated pipe connector, causes this corrugated pipe connector using scope to dwindle greatly, and inconvenience is promoted.
The model utility content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bellows to be difficult for breaking away from corrugated pipe connector and the bigger corrugated pipe connector of using scope.
The technical solution of the utility model is achieved in that a kind of corrugated pipe connector, comprise joint body and tightening cover that hollow arranges, this joint body is disposed with the inserted part from top to bottom, joint and fixing part, tightening cover is provided with the through hole that passes for bellows, tightening cover adopts with joint and is threaded, the inserted part comprises some clamping blocks, this clamping block equidistantly is arranged on the top edge of joint, tightening cover is provided with and drives the inclined-plane that clamping block is held tightly to the centre, the inside of this joint also is provided with the positioning pipe that hollow arranges, and the top that the upper edge of this positioning pipe is higher than clamping block arranges.
By adopting technique scheme, the positioning pipe that arranges can be sheathed for bellows, plays the effect of location, and when clamping block is held tightly, each clamping block and positioning pipe play the effect of clamping bellows, have prevented that effectively the softening situation that breaks away from corrugated pipe connector of bellows from taking place.
The utility model further is set to: at least one clamping block is provided with projection towards a side of positioning pipe.
By adopting technique scheme, this projection can snap in the cavity of bellows surface, further the spacer dimple pipe.
The utility model also further is set to: each clamping block is provided with projection towards a side of positioning pipe.
By adopting technique scheme, improved the stability of clamping, make connection more reliable, improved using scope.
The utility model also further is set to: the cross section of described projection is trapezoidal setting.
By adopting technique scheme, simple in structure, be easy to processing, be convenient to the cavity clamping with bellows surface.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment structure explosive view;
Fig. 2 is the partial sectional view that corrugated pipe connector is connected with bellows in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-shown in Figure 2, the utility model discloses a kind of corrugated pipe connector, comprise joint body 1 and tightening cover 2 that hollow arranges, this joint body 1 is disposed with inserted part 11 from top to bottom, joint 12 and fixing part 13, tightening cover 2 is provided with the through hole 21 that passes for bellows 3, tightening cover 2 adopts with joint 12 and is threaded, wherein the outer wall of joint 12 is provided with outside thread, the inwall of tightening cover 2 is provided with internal thread, inserted part 11 comprises some clamping blocks 111, this clamping block 111 equidistantly is arranged on the top edge of joint 12, tightening cover 2 is provided with and drives the inclined-plane 22 that clamping block 111 is held tightly to the centre, in the utility model specific embodiment, the inside of this joint 12 also is provided with the positioning pipe 13 that hollow arranges, the top that the upper edge of this positioning pipe 13 is higher than clamping block 111 arranges, the positioning pipe that arranges can be sheathed for bellows 3, play the effect of location, and when clamping block is held tightly, each clamping block and positioning pipe play the effect of clamping bellows, have prevented that effectively the softening situation that breaks away from corrugated pipe connector of bellows from taking place.
In the utility model specific embodiment, each clamping block 111 is provided with projection 1111 towards a side of positioning pipe, and the cross section of each projection 1111 is trapezoidal setting, this projection 1111 can snap in the cavity of bellows surface, further the spacer dimple pipe has improved the stability of clamping, makes connection more reliable, improved using scope, wherein, projection is set to trapezoidal, and is simple in structure, be easy to processing, be convenient to the cavity clamping with bellows surface.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
