Abstract
The invention relates to the technical field of tubular product assembly, in particular to a tubular product connecting structure. The tubular product connecting structure comprises a first tube body and a second tube body. The first tube body is sleeved with a sleeve, an annular space allowing the second tube body to be inserted therein is formed between the inner wall of the sleeve and the outer wall of the first tube body, the outer wall of the second tube body and the inner wall of the sleeve are connected in a threaded mode, a clamping sleeve is arranged in the space between the end of the second tube body and the sleeve, the outer wall of the clamping sleeve is compressed by the inner wall of the sleeve and the inner wall of the second tube body, the inner wall of the clamping sleeve makes tight contact with the outer wall of the first tube body, and a step face jacking the end face of the first tube body is arranged in the second tube body. The tubular product connecting structure is simple, reasonable in design, convenient to assemble and disassemble and capable of guaranteeing the sealing performance between the first tube body and the second tube body.
Description
Technical field
The present invention relates to tubing mounting technology field, be specifically related to a kind of pipe connecting structure.
Background technique
In prior art when being connected by two tubing, one is the mode adopting welding, but such mode is for being fixedly connected with mode, after two tubing weld together, is just not easy separately; Two is adopt the mode of locking nut to connect, although this kind of mode is for convenience detach, the sealing between two tubing can not be guaranteed.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of pipe connecting structure of reasonable in design, it both so that mounting or dismounting, also can ensure the sealing of joint between tubing.
Realize technological scheme of the present invention as follows:
A kind of pipe connecting structure, comprise the first body, the second body, first body is arranged with sleeve pipe, the annular space inserted for the second body is formed between internal surface of sleeve pipe and the first tube wall, second tube wall is connected with adopting engagement thread between internal surface of sleeve pipe, be provided with in space between the end and sleeve pipe of the second body and hold cover, this outer wall holding cover compresses by internal surface of sleeve pipe and the second inboard wall of tube body, hold inwall and the first tube wall close contact of cover, in the second body, be provided with the step surface withstanding the first body end face.
Have employed technique scheme, during assembling, by casing pipe sleeve on the first body, hold cover and put into annular space, the one end holding cover withstand in sleeve pipe formed spacing, again the second body is inserted in annular space, starting turn sleeve pipe like this makes sleeve pipe and the second body realize being threaded, after sleeve pipe precession puts in place, the compression being subject to the second body is inserted in the front end holding cover, holding cover is pressed on the first body, the first body can be realized like this be connected with the firm of the second body, on the end face tightening of the other first body step surface in the second body, realize sealing, structure of the present invention is simple, reasonable in design, and one is conveniently to install and remove, and two is to ensure the sealing between the first body, the second body.
Further, undertaken compressing and further ensureing sealing by the inwall of the second body for the ease of holding in cover insertion second body, described second inboard wall of tube body is arc surface with holding the surface of contact overlapping outer wall.
Further, in order to ensure sealing between the first tube wall and the second inboard wall of tube body and to pack into line stabilization spacing to holding, the described front end holding cover has and holds mouth, and the second body is provided with for inserting the fixture block holding mouth, the inwall of this fixture block contacts with the first body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1, a kind of pipe connecting structure, comprise the first body 1, second body 2, first body is arranged with sleeve pipe 3, the annular space 4 inserted for the second body is formed between internal surface of sleeve pipe and the first tube wall, second tube wall is connected with adopting engagement thread between internal surface of sleeve pipe, be provided with in space between the end and sleeve pipe of the second body and hold cover 5, this outer wall holding cover compresses by internal surface of sleeve pipe and the second inboard wall of tube body, hold inwall and the first tube wall close contact of cover, in the second body, be provided with the step surface 6 withstanding the first body end face.Second inboard wall of tube body is arc surface 7 with holding the surface of contact overlapping outer wall.The design of arc surface is to increase the surface of contact holding cover outer wall and the second inboard wall of tube body, to ensure sealing, is also convenient to hold in cover insertion second body simultaneously, certainly may also be here and be arranged to conical surface; The front end holding cover has and holds mouth 8, and the second body is provided with for inserting the fixture block 9 holding mouth, the inwall of this fixture block contacts with the first body, can ensure the sealing of the first tube wall and the second inboard wall of tube body like this.
Using process of the present invention: during assembling, by casing pipe sleeve on the first body, hold cover and put into annular space, the one end holding cover withstand in sleeve pipe formed spacing, again the second body is inserted in annular space, starting turn sleeve pipe like this makes sleeve pipe and the second body realize being threaded, after sleeve pipe precession puts in place, the compression being subject to the second body is inserted in the front end holding cover, holding cover is pressed on the first body, the first body can be realized like this be connected with the firm of the second body, on the end face tightening of the other first body step surface in the second body, realize sealing, when dismantling, as long as the second body and the first body just can separate by turn sleeve pipe backward, use very convenient.
The above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
