Abstract
The utility model discloses a spinning bamboo joint shaped air conditioner tube which comprises a metal tube (1), a bamboo joint shaped connector (2) and a tube sleeve (3); the metal tube (1) and the bamboo joint shaped connector (2) are integrated as a whole; and the tube sleeve (3) is limited on the metal tube (1) in the axial direction. The metal tube and the bamboo joint shaped connector of the air conditioner tube are integrated as a whole with no welding seam, so that the spinning bamboo joint shaped air conditioner tube provided by the utility model can bear larger pressure and be used under the environment of larger pressure and corrosion with low probability of leakage; moreover, the tube sleeve is limited on the metal tube in the axial direction, so that the tube sleeve and the metal tube can slide freely in the circumferential direction, further, the generation of welding seams is reduced, and leakage is avoided effectively.
Description
Technical field
The utility model relates to a kind of air conditioning for automobiles pipe, specifically is the spinning laemodipodiform air-conditioning pipe that a kind of automobile means for air conditioner uses.
Background technology
The spinning laemodipodiform air-conditioning pipe of prior art comprises metal tube, laemodipodiform joint and pipe box, and described laemodipodiform joint is welded on an end of metal tube, and described pipe box is welded on the outer wall of laemodipodiform joint.There is following defective in the spinning laemodipodiform air-conditioning pipe of said structure in the use of reality: because laemodipodiform joint and metal tube are welding, and be the metal of thinner thickness owing to metal tube, laemodipodiform joint, therefore after welding, can cause that the character of metal changes around the weld seam.Again after long-term the use, be subjected to the pressure influence in the air-conditioning pipe and the corrosion of surrounding environment, so the weld seam on the spinning laemodipodiform air-conditioning pipe is easy to crack, leak then.In addition, because pipe box is welded on the laemodipodiform joint, therefore might influences the seal of laemodipodiform joint, and then leak.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of antileakaging spinning laemodipodiform air-conditioning pipe is provided.
The technical solution of the utility model is, a kind of spinning laemodipodiform air-conditioning pipe is provided, and comprises metal tube, laemodipodiform joint and pipe box, and described metal tube and laemodipodiform joint are an integral body; Described pipe box axial limiting is on metal tube.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model is because laemodipodiform joint and metal tube are an integral body, no weld seam exists, so the utility model spinning laemodipodiform air-conditioning pipe can bear bigger pressure, and under the influence of pressure and corrosion, spinning laemodipodiform air-conditioning pipe is difficult for cracking, and promptly is difficult for leaking.And because the pipe box axial limiting is on metal tube, pipe box and metal tube can circumferentially be free to slide, so have further reduced the generation of weld seam, and then have avoided leakage effectively.
As improvement, the outer wall of described metal tube is provided with the projection of two annulars, and the flanging of the less end of described pipe box caliber is located between the projection of two annulars.Because pipe box and metal tube adopt above-mentioned connected mode, therefore further to have avoided welding the influence that spinning laemodipodiform air-conditioning pipe is caused, thereby further guaranteed the functional reliability of spinning laemodipodiform air-conditioning pipe, it is difficult for producing under the situation of high pressure leaking.
Description of drawings
Fig. 1 is the structural representation of the utility model spinning laemodipodiform air-conditioning pipe.
Fig. 2 be the utility model spinning laemodipodiform air-conditioning pipe partly cut open structural representation.
Shown in the figure 1, metal tube, 2, the laemodipodiform joint, 3, pipe box, 4, projection.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of spinning laemodipodiform of the utility model air-conditioning pipe comprises metal tube 1, laemodipodiform joint 2 and pipe box 3, and described metal tube 1 and laemodipodiform joint 2 are an integral body; Described pipe box 3 axial limitings are on metal tube 1, and promptly pipe box 3 can circumferentially slide with metal tube 1, but cannot endwisely slip.
The outer wall of described metal tube 1 is provided with the projection 4 of two annulars, the flanging of the less end of described pipe box 3 calibers is located between the projection 4 of two annulars, be that the bigger end of pipe box 3 calibers does not have flanging, the less end of caliber has an inside flanging, and described inside flanging is located at the centre of two annular protrusions 4.
Add man-hour, the annular protrusion 4 of on metal tube 1, upsetting out earlier, the end at metal tube processes laemodipodiform joint 2 then, pipe box 3 is penetrated in the metal tube 1 again, another annular protrusion 4 of upsetting out at last.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (2)
1. a spinning laemodipodiform air-conditioning pipe comprises metal tube (1), laemodipodiform joint (2) and pipe box (3), it is characterized in that: described metal tube (1) and laemodipodiform joint (2) are an integral body; Described pipe box (3) axial limiting is on metal tube (1).
2. spinning laemodipodiform air-conditioning pipe according to claim 1 is characterized in that: the outer wall of described metal tube (1) is provided with the projection (4) of two annulars, and the flanging of the less end of described pipe box (3) caliber is located between the projection (4) of two annulars.
