[Prior art]

 In ordinary homes and single houses, hanger racks are often used to hang clothes and store them. In particular, as shown in Fig. 1, telescopic pipes are used for both vertical and horizontal pipes on both sides, and height and length are used. Those that can be adjusted according to space and can be operated according to the space have become widespread. However, most of the positioning devices for the telescopic pipes of such a hanger rack are of a type that tightens screws, that is, a fixing sheet is provided at the end of the outer tube, a screw hole is provided through the fixing sheet, and a bolt is provided. Was screwed into it and the bolt pressed against the inner tube surface to achieve the positioning effect. However, it is difficult to grasp the bolts tightly, and if the tightening is insufficient, the inner pipe may fall off if the amount of clothing to be hung increases, and especially the vertical pipe positioning device has a large load. It was easy for the sliding phenomenon to occur. Also, since metal material is used for the bolt and stainless steel pipe or electroplated metal pipe is used for the telescopic pipe, when the front end of the bolt applies pressure and rotational force to the inner pipe surface, Severe abrasion is likely to be formed, and after repeated use, many scars and severe dents may occur on the inner tube surface, possibly damaging the appearance of the entire hanger rack. As described above, the known method of positioning a telescopic pipe by tightening bolts on a hanger rack has a problem that if the tightening is insufficient, the inner pipe slides out, and if the tightening is too strong, the inner pipe is damaged and dents are generated. There was a need for improvement.

[Problems to be solved by the invention]

 The present invention adopts an eccentric cam type locking lever with a clear rotating state in the telescopic pipe positioning device of the hanger rack, thereby solving the problem that it is difficult to grasp the tightening condition in the conventional technology, By designing the pressing surface of the pressing block of the locking lever used for tightening to have a radian close to the circumference of the inner pipe, it is possible to position the telescopic pipe without damaging the inner pipe surface That is the issue.

[Means for Solving the Problems]

 The invention of claim 1 comprises a tubular fixing sheet 3 fitted around the outer periphery of the end of the outer pipe 1 of the extendable pipe of the hanger rack, and a retaining ring 31 protruding into the upper end of the inner periphery of the fixing sheet 3. The fixed sheet 3 is supported by the lower end surface of the retaining ring 31 on the upper end surface of the outer tube 1. One rectangular through hole 32 is provided in the retaining ring 31, and the through hole is provided. One shaft seat 33 is protruded from each outer wall on both sides of the shaft 32, and one locking lever 34 is connected between the two shaft seats 33 by one shaft 332, and one end of the locking lever 34. Is a pressing block 341 that fits into the through hole 32. When one lever portion 342 is extended behind the pressing block 341 and the lever portion 342 of the locking lever 34 is turned upward, The holding block 341 rotates eccentrically and separates from the surface of the inner tube. When the lever portion 342 is pushed down, the pressing block 341 presses the surface of the inner tube 2 to achieve positioning, and the telescopic pipe positioning device of the hanger rack having the above configuration is provided. .

According to a second aspect of the present invention, the pressing surface of the pressing block 341 of the locking lever 34 used for locking the inner tube is a concave arc surface corresponding to the surface of the inner tube 2. The hanger rack telescopic pipe positioning device described in (1).

The invention according to claim 3 is the apparatus for positioning a telescopic pipe of a hanger rack according to claim 1, wherein the locking lever 34 of the fixed sheet 3 is provided in the same direction as or perpendicular to the axial direction of the telescopic pipe.

[Embodiment of the invention]

 2 and 3 are a perspective view of a hanger rack using the positioning device of the present invention and an exploded perspective view of the present invention. As shown in these figures, the present invention comprises a tubular fixing sheet 3 fitted around the outer end of the outer pipe 1 of the telescopic pipe, and a stopper projecting into the upper end of the inner circumference of the fixing sheet 3. A ring 31 is provided, and the thickness of the projection forms a supported surface supported on the upper end surface of the outer tube 1, whereby the retaining ring 31 protrudes above the outer tube 1 (see FIG. 4). The inner diameter of the retaining ring 31 is substantially equal to the outer diameter of the inner tube 2, and the inner wall of the retaining ring 31 is slidably abutted on the outer wall of the inner tube 2. Also, one rectangular through hole 32 is provided at an appropriate position of the retaining ring 31 of the fixing sheet 3, and one shaft seat 33 is provided on each of outer walls on both sides of the through hole 32, and these two shaft seats are provided. A shaft hole 331 corresponding to 33 is provided, one shaft 332 is passed therethrough, a locking lever 34 is pivotally connected to the shaft 332, and the locking lever 34 is sandwiched between the two shaft seats 33, and A pressing block 341 that fits into the through hole 32 is provided at the pivotal end of the stop lever 34, and one lever portion 342 extends behind the pressing block 341, and the pressing surface of the pressing block 341 is A concave arc surface corresponding to the surface of the inner tube 2 is provided, and a pressing area with respect to the inner tube is provided widely. As shown in FIG. 4, when the lever portion 342 of the locking lever 34 is turned upward, the pressure holding block 341 is separated from the surface of the inner tube 2, and the inner tube 2 is in a stretchable state. When the portion 342 is turned downward, as shown in FIGS. 5 and 6, the concave arc-shaped pressing surface of the pressing block 341 presses the surface of the inner tube 2, and at this time, the concave arc of the pressing surface Due to the shape, the pressing surface is completely adhered to the inner tube 2, and the large pressing area securely pinches and positions the inner tube 2, making the inner tube 2 inextensible. The locking lever 34 is made of a plastic material and does not damage the surface of the inner tube 2 and does not form a depression. Although the above is the embodiment in which the locking lever 34 is installed vertically, the same effect can be achieved by installing the locking lever 34 horizontally so that the inner tube and the outer tube are perpendicular to each other. To FIG.
