The present invention relates to the field of furniture, and in particular, relates to an assembly structure of a different landscape pipe.

The assembly structure of the existing furniture implements a detachable function by inserting and connecting different landscape pipes in order to reduce the length of the piping member. The conventional structure of the diffraction tube includes a sleeve and an insertion tube that are inserted and connected in a combination, and by processing the end of the insertion tube to form a diffraction tube, the insertion tube is sleeved in the axial direction through the diffraction tube. The sleeve and the insertion tube are fixedly connected in the axial direction by being inserted into the end of and being fixedly connected through the fastening member again. For the convenience of processing, both the sleeve and the insertion tube according to the prior art are circular tubes, and in order to securely connect through the fastening member, a through hole is formed in advance in the sleeve. This structure has the following disadvantages. exist. That is, the weak radial deformation prevention performance of the circular pipe deteriorates the deformation prevention performance of the pipe member, thereby affecting the experience of use; On the other hand, when processing into a square tube, the shape of each section at the end edge of the insertion tube does not match, so that each section at the end edge of the insertion tube cannot be contracted in a balanced manner. Increase the difficulty. And, since the sleeve must be drilled from the outside to the inside, a burr is created at the edge of the port inside the through hole, and when the diffraction tube is inserted into the sleeve, the burr interferes with the insertion of the diffraction tube. It increases the manufacturing cost because it has to be added.

In order to solve the problems of the prior art, the object of the present invention is to install the cross-sectional shape of the sleeve and the insertion tube in a square shape so that the piping member has excellent radial deformation prevention performance, so it is convenient to disassemble and transport, It is to provide an easy-to-process different-view pipe assembly structure that can extend the service life of piping members and improve the experience.

The present invention is implemented through the following method. The easy-to-process heterogeneous pipe assembly structure according to the present invention includes a sleeve and an insertion tube whose cross-sectional shape is all square, and a different view tube is formed at the end of the insertion tube, and the cross-sectional shape of the outer wall of the outer wall is the sleeve end. It is smaller than the cross-sectional shape of the inner wall of and after being installed at a designated position, the end of the sleeve is disposed overlaid on the outer tube of the insertion tube so that the sleeve and the insertion tube are inserted and connected in the axial direction. Since the cross-sectional shape of the sleeve and the insertion tube is installed in a square shape, and the sleeve and the insertion tube have four walls perpendicular to each other, the piping member has excellent radial deformation prevention performance, so it is convenient to disassemble and transport. It can extend the service life of the member and improve the use experience. The insertion tube is inserted into the end of the sleeve through the ear canal so that the outer wall of the ear canal and the inner wall of the sleeve end are in close contact, thereby ensuring that the insertion tube and the sleeve are fixedly connected in the axial direction.

Preferably, the cross-sectional shape of the outer wall of the diffraction tube is square, and the wall surface of the diffraction tube is recessed inward to form a collision preventing groove, and the collision preventing groove is installed along the axial direction of the diffraction tube. The anti-collision groove improves the deformation-prevention performance of the hetero-diameter tube, so that the outer wall of the hetero-diameter tube is in close contact with the inner wall of the end of the sleeve, and also effectively accommodates the remaining section formed by processing the different view tube, so that the shape of the different view tube meets the design requirements. Match.

Preferably, the axial projection of the different landscape tube is included in the axial projection of the inner wall of the sleeve, and after installation at a designated position, the groove entrance edge of the collision preventing groove is in close contact with the inner wall of the sleeve. The ear canal is inserted in the sleeve in the axial direction, and the contact area between the ear canal and the sleeve is increased to improve connection stability, and furthermore, it ensures that the axis of the sleeve and the insertion tube is positioned in the same straight line.

Preferably, the axial projection of the middle section of the insertion tube overlaps with the axial projection of the sleeve. The end of the sleeve is overlaid on the otoscopic tube and is in close contact with the middle section of the insertion tube so that the edge of the sleeve and the middle section of the insertion tube are neatly connected.

Preferably, the circumference of the outer wall of the outer wall is the same as the circumferential direction of the outer wall of the sleeve. The axial end edge of the insertion tube is compressed and deformed from the original long-sided rectangle to form a short-sided long direction, and in the process of forming a different diameter tube, the length of the side changes from the long side to the short side, and the remaining raw material formed is bent to form a collision preventing groove. The circumference of the cross section in the radial direction of the tube is equal to the circumference of the cross section in the radial direction of the middle section of the insertion tube, and the circumference of the cross section in the radial direction of the end of the sleeve is also the same.

Preferably, collision prevention grooves are installed on all of the walls of the different landscape pipes. This landscape pipe has four walls installed vertically to each other, and collision prevention grooves are installed on each wall to effectively accommodate the remaining raw materials formed as each edge contracts, and furthermore, the wall surface of each edge is smooth as required. Ensure to shrink.

Preferably, the anti-collision groove is installed in the middle of the corresponding wall surface of the diffraction tube. The anti-collision groove effectively accommodates the remaining raw materials on both sides of the wall where the anti-collision groove is located so that the shape of the square of the radial cross section of the different diameter tube is identical, so that the installation is convenient.

Preferably, a screw hole penetrated in a radial direction is installed on the wall surface of the outer diameter pipe, a through hole overlapping the radial projection of the screw hole is installed at the end of the sleeve, and after being inserted and connected at a designated position , The fastening member passes through the through hole from the outside to the inside and is connected by a screw to the corresponding screw hole. The fastening member penetrates through the through hole and is connected by a screw hole and a screw to limit the position of the insertion tube and the sleeve in the axial direction to prevent separation of the diffraction tube from the inside of the sleeve, to ensure connection stability, and to prevent rotation. It also serves to limit.

Preferably, the screw hole is installed on the bottom surface of the groove of the collision prevention groove, and after being inserted and connected to a designated position, a space is formed between the inner port edge of the through hole and the outer port of the screw hole. When processing through-holes, burrs are created at the edges of the inner ports of the through-holes, and since the spaced space is formed, burrs are hidden in the spaced space in the process of covering the sleeve, thereby preventing the burr. There is no need for polishing, effectively simplifying the processing step and improving the assembly efficiency. After installation at the designated location, the burr is hidden in the spaced space and does not come into contact with the user, so the safety of use can be guaranteed. The collision avoidance groove and the inside of the sleeve are surrounded to form a spaced apart.

Preferably, the sleeve and the insertion tube are fixedly connected through at least one fastening member. The fastening member not only restricts the insertion tube from being separated from the sleeve in the axial direction, but also fixes the circumferential position between the insertion tube and the sleeve.

The present invention has the following beneficial effects. By installing the cross-sectional shape of the sleeve and the insertion tube in a square shape, the piping member has excellent radial deformation prevention performance, which is convenient not only to disassemble and transport, but also extends the service life of the piping member and improves the use experience. In addition, by using the collision avoidance groove to accommodate the remaining raw materials, the processing precision of the diffraction pipe is improved, and the collision prevention groove provides an accommodation space for burrs, which is convenient for assembly.
