Description

  The present invention relates to a cone bar, and in particular, the inner and outer cylinders are covered with each other, and are provided on the surface of the inner cylinder over the expansion and contraction operation of the inner and outer cylinders using a stopper ring and a support ring provided at the ends of the inner and outer cylinders. This refers to a corn bar that retains a good reflection effect because no scratches due to friction occur in the reflecting material, and it is possible to prevent scratching due to contact of the reflecting material of the outer cylinder with the ground.

  The current cone bar (as shown in FIGS. 1 and 3) is configured such that the inner cylinder 10 and the outer cylinder 11 are covered with each other, and the locking ring 100 and the locking ring provided outside the inner and outer cylinders. 110 is fitted to two adjacent cones to achieve the function of safety marking. This type of cone bar consists of inner and outer cylinders, and the inner and outer cylinders are designed to be extendable and retractable, making them convenient for storage and transportation. In order to provide this, it is necessary to provide the stopper ring 101 and the stopper ring 111 inside the inner and outer cylinders. There are two types of the stopper ring 101 and the stopper ring 111 as shown in FIGS. In this case, an extremely thin stopper ring 101 is provided on the outer periphery of the inner cylinder, and another stopper ring 111 is fixed to the inner periphery of the outer cylinder. Therefore, when the two stopper rings 101 and the stopper ring 111 lean against each other, the inner and outer It is possible to prevent the cylinder from coming out when it is extended to the maximum length. Since the stopper ring can be formed into an arcuate shape when the stopper ring is fixed, the stopper ring is attached to the reflector 102 on the surface of the inner cylinder when the inner and outer cylinders are extended or contracted. Scratches due to friction can be avoided, but the disadvantage is that the stopper ring 101 and the stopper ring 111 only have a function of preventing the inner and outer cylinders from dropping, and the two areas are not large. If it extends to the length of, there is no support for supporting the ends of the inner and outer cylinders, and the center part hangs down as shown in FIG. In addition, since the surface of the inner portion 103 of the outer cylinder surface is not affixed to the ground, what is conventionally known as shown in FIG. 1 is a part of the outer cylinder when placed on the ground. The area comes into contact with the ground, and the ground causes scratches on the reflective material on the surface of the outer cylinder, which affects the safety design with nighttime reflection required as a bar body.

  FIG. 2 shows another type of conventionally known one. In the inner cylinder 13 and the outer cylinder 14, the inside of the inner cylinder is separately processed into a mouth shape, and the outer cylinder is condensed inside. After that, the inner and outer cylinders are put on top of each other, and the inner and outer cylinders 130 and the condensing port 140 of the outer cylinder collide with each other. Speaking of its disadvantages, the conventionally known one such as 2 is that the condensation port portion of the outer cylinder 14 is an extension from the front wall 141 of the pipe, and the front wall 141 exhibits a pointed state. When the inner and outer cylinders are expanded and contracted, the reflecting material 142 on the surface of the inner cylinder is rubbed to cause scratches, which affects the reflection effect of the reflecting material. Next, since there is no support at the center part 143 of the surface of the outer cylinder, FIG. 2 is caused by friction with respect to the reflector 142 on the surface of the outer cylinder when the ground L is placed on the ground as shown in FIG. Causes scratches and affects the reflective effect. Furthermore, if the inner and outer cylinders are subjected to processing such as expanding the mouth or shrinking the mouth as it is, processing is difficult and time-consuming, which affects the bar processing and production speed.

  Therefore, the inventors of the present invention have come up with the present invention by studying the shortcomings of the above-mentioned known ones for many years with experience accumulated from designing and processing to related products. It is the wound actuator of the present invention.

  The corn bar according to the present invention provides a corn bar that can increase the speed of a kind of processing and prevent the undue scratches caused by the friction of the reflecting material from affecting the reflection effect.

  The cone bar of the present invention has inner and outer cylinders covering each other, and in each of them, a stopper ring is provided at one end of each of the inner and outer cylinders, and the two stopper rings are all convex. The stopper ring fixed to the inner cylinder is the inner circumference to put the inner cylinder, and the stopper ring fixed to the outer cylinder is the outer circumference to cover the outer cylinder, so the stopper rings of the inner and outer cylinders collide with each other, The stability when expanding and contracting can be maintained.

  In the cone bar of the present invention, the outer circumference of the thick ring of the stopper ring of the inner cylinder is balanced with the inner circumference of the outer cylinder, and the inner circumference of the thin ring of the stopper ring of the outer cylinder is balanced with the outer circumference of the inner cylinder. The stopper ring of the inner cylinder and the stopper ring of the outer cylinder can be used as a support for the central part so that the central part of the bar never hangs even when the inner and outer cylinders are extended to the longest state.

Therefore, in order to understand the present invention, it will be described as follows with reference to the attached drawings.
As shown in FIG. 4, the cone bar according to an embodiment of the present invention has an inner cylinder 2, and a reflective material 20 is pasted on the outer surface of the inner cylinder 2, and the reflective material 20 has a more conspicuous color such as red or orange. In addition, a locking ring 22 is fixed to one end 21 of the inner cylinder, and a pipe tip 220 and a ring tip 221 are provided on the locking ring 22, and a hole 220 of the pipe tip 220 is formed at one end of the inner cylinder. 21 and tightened with a screw 2211, the locking ring 22 can be completely fixed to one end 21 of the inner cylinder 2, and the bar is hung between the two cones 4 at the ring tip 221 (as shown in FIG. 7). be able to. Next, a stopper ring 24 is provided at the other end 23 of the inner cylinder 2, the stopper ring 24 of the inner cylinder 2 has a convex shape, and the stopper ring 24 is provided with a thin ring 240 and a thick ring 241. Yes, a thin ring 240 can be put into the hole 230 in the other end 23 of the inner cylinder 2.

  There is an outer cylinder 3, and the reflective material 30 is pasted on the outer surface of the outer cylinder 3, like the surface of the inner cylinder 2, and the reflective material 30 has a more conspicuous color such as red or orange. A lock ring 32 is fixed to one end 31, and a pipe tip 320 and a ring tip 321 are provided on the lock ring 32. A hole 3200 of the pipe tip 320 is put on the one end 31 of the outer cylinder and tightened with a screw 3211. The locking ring 32 can be completely fixed to the one end 31 of the outer cylinder 3, and the bar can be hung on both cones 4 (as shown in FIGS. 7, 8, and 9) at the ring tip 321. Next, a stopper ring 34 is provided at the other end 33 of the outer cylinder 3, and the stopper ring 34 of the outer cylinder 3 has a convex shape, and the stopper ring 34 is provided with a thin ring 340 and a thick ring 341. Yes, a thick ring 341 can be placed on the outside of the other end 33 of the outer cylinder 3 (shown in FIGS. 4, 5 and 6).

  Therefore, when the inner cylinder 2 and the outer cylinder 3 are combined, the stopper ring 24 and the stopper ring 34 of the inner cylinder 2 and the outer cylinder 3 are first combined, and the one end 21 of the inner cylinder 2 is connected to the outer cylinder. 3 is inserted into the inner hole 310 of the outer cylinder (as shown in FIGS. 5 and 6), and the inner cylinder 2 is extended from the outer cylinder 3 so that the inner cylinder 2 and the outer cylinder 3 When the locking ring 22 and the locking ring 32 at the exposed one end 21 and one end 31 are fixed, the combination of the cone bars of this embodiment can be completed. Therefore, when the inner cylinder 2 is expanding and contracting in the inner hole 310 of the outer cylinder 3, the outer periphery of the thick ring 241 of the stopper ring 24 of the inner cylinder 2 is the inner periphery of the inner hole 310 of the outer cylinder 3. The outer cylinder 3 is balanced, and the outer circumference of the inner cylinder 2 is balanced with the inner circumference of the thin ring 340 of the stopper ring 34 of the outer cylinder 3, and the thick ring 241 of the stopper ring 24 and the thin ring 340 of the stopper ring 34 are balanced. And the inner cylinder 2 and the outer cylinder 3 are covered with each other, and the thick ring 241 of the stopper ring 24 and the thin ring 340 of the stopper ring 34 are respectively connected to the inner holes of the outer cylinder 3. When the inner cylinder 2 and the outer circumference of the inner cylinder 2 are brought into contact with each other (as shown in FIG. 6), even if the inner cylinder 2 extends to the maximum length, the center portion of the bar does not hang down. Further, since the outer circumference of the thick ring 241 of the stopper ring 24 is larger than the outer circumference of the inner cylinder 2 and the outer circumference of the thick ring 341 of the stopper ring 34 is larger than the outer circumference of the outer cylinder 3, the cone bar of this embodiment is placed on the ground. Even if placed, there is no problem of contact with the ground or damage to the reflector. Further, since the contact portion 342 between the stopper ring 34 of the outer cylinder 3 and the surface of the inner cylinder 2 is also formed in an arc shape, even if the inner cylinder 2 and the outer cylinder 3 expand and contract, the reflecting material is completely damaged. In this case, the present embodiment has extremely practical value.
