Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pipe clip.

[0002]

[Prior art]

 As shown in FIG. 1, the structure of the conventional pipe clip has a design in which an inner pipe 2 and an outer pipe 1 having different pipe diameters are adopted, and two pipe bodies are assembled by a fixing jig 3.

[0003]

[Problems to be solved by the invention]

 FIG. 2 is a schematic view showing an assembled state of the conventional structure. However, according to this type of structure, it is difficult to directly assemble and assemble, and a smooth surface is required. Since the inner tube 2 has no mark and has no engaging effect, the inner tube 2 is easily detached from the circular hole 11 of the outer tube 1 when subjected to an external force. However, the back side of the engaging piece 33 is a simple arc-shaped projection 331 ', and the surface of the inner tube 2 is smooth. For this reason, when the assembling work is performed in an engaged manner, the circular hole 312 at the bottom of the fixing jig 3 is fitted into one end of the outer tube 1, while the one end of the inner tube 2 is fitted at the circular hole 312. After the user adjusts the position of the inner tube 2 according to the required altitude, the finger presses the pusher 332 of the engaging piece 33 to bring the engaging piece inner edge 333 close to the jig outer edge 314. 'Engages the inner tube 2 with a smooth surface. Since the mark is not completely attached to the surface of the inner tube 2, it is difficult to directly assemble the conventional tube, and since the inner tube 2 has no locking effect, it cannot be detached from the outer tube 1. Often there.

FIG. 3 is a schematic cross-sectional view of the structure of a conventional pipe clip. According to the structure of the conventional pipe clip, when the inner edge 333 of the engaging piece approaches and approaches the outer edge 314 of the jig. In addition, the arc-shaped projection 331 'locks the inner tube 2 having a smooth surface, and since the surface of the inner tube 2 is not completely marked, it is difficult to directly assemble the conventional one. In addition, since the inner tube 2 has no locking effect, the inner tube 2 is often detached from the circular hole 11 of the outer tube 1. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pipe clip which can be directly engaged to perform an assembling operation, and in which an inner tube is not easily detached from an outer tube.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the pipe clip according to claim 1 of the present invention mainly includes an inner tube, an outer tube, and a fixing jig, and the inner tube and the outer tube are engaged with the fixing jig. The inner tube is a pipe clip that is inserted into the outer tube. An annular groove is provided at a predetermined position of the inner tube, and a mark is provided near the annular groove of the inner tube. On the other hand, locking projections are provided on the inner side of the engaging piece that match the number and position of the annular grooves, and the marks allow the engaging projections of the fixing jig to be accurately engaged in the annular grooves. And, after the assembly work of the inner pipe and the outer pipe is directly involved, the inner pipe does not easily come off the outer pipe.

[0006] The pipe clip according to claim 2 of the present invention is the pipe clip according to claim 1, wherein the locking projection and the annular groove adopt a design that matches each other, and the width and the number thereof are within. It can be set freely according to the weight that the tube can receive. The pipe clip according to the third aspect of the present invention is the pipe clip according to the first aspect, wherein the number of the engaging pieces can be freely set according to the weight that the inner pipe can receive.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 4 shows a pipe clip according to an embodiment of the present invention. A plurality of annular grooves 21 are provided mainly at predetermined positions on the surface of the inner tube 2, and a mark 22 is provided on the surface of the inner tube 2 adjacent to the annular groove 21. Thereby, the fixing jig 3 can be easily positioned. An engaging piece 33 is provided on the fixing jig 3, and a locking projection 331 on the back side of the engaging piece 33 can be accurately locked and positioned in the annular groove 21, and has an effect of stopping the inner tube 2. Have.

As shown in FIG. 5, in the pipe clip according to the present embodiment, a fixing port 313 is provided in the seat 31 of the fixing jig 3, and after the engaging piece 33 is inserted into the fixing port 313, the fixing pin 32 is removed. It can be inserted into the insertion hole 311 and the fixed insertion hole 334. When the pusher 332 is pulled inward by a finger, the locking projection 331 is completely locked by the plurality of annular grooves 21 on the surface of the inner tube 2 and positioned. At this time, even if an external force is applied to the inner tube 2, the inner tube 2 does not separate from the outer tube 1. In addition, the annular groove 21 on the surface of the inner tube 2 and the locking projection 331 on the back side of the engaging piece 33 are designed to match each other. The number of the engagement pieces 33 can be freely set according to the weight of the inner tube 2.

Finally, FIG. 6 is a schematic diagram showing an assembled state of the structure of the pipe clip according to the present embodiment. Since the annular groove 21 on the surface of the inner tube 2 and the locking projection 331 on the back side of the engaging piece 33 are designed to fit each other, the width and quantity thereof can be freely set according to the needs of the inner tube 2. .

[0010]

[Effect of the invention]

 The present invention has the following effects. The user can engage the inner pipe and the outer pipe and directly perform the assembling work according to the invention. Since it has the effect of locking the inner tube, it does not separate from the outer tube.
