DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) The technical characteristics, contents, advantages and effects of the present invention will be apparent with the detailed description of preferred embodiments accompanied with related drawings as follows.

(13) With reference to FIGS. 3-7 for a cord protector 2 according to the embodiment of the present invention, the structure is formed by co-assembling a first protection seat 21 and a second protection seat 22. The first protection seat 21 and the second protection seat 22 are made of a flexible material that resists impact, such as synthetic rubber, rubber doped with synthetic resin, etc.. An external side surface of the first protection seat 21 is a circle arc cone having a narrow front and a wide rear condition, while an inner side is a flattened shape. A bottom of the flattened inner side is an opening 211. Two end inner sides of the opening 211 are respectively recessed to form a joining cavity 212. The opening 211 is extended toward the top portion and enlarged and, while reaching the top portion, is divided by a cross bar 213 to form two through grooves 214. The lateral cross-section of the cross bar 213 is a triangular pyramid having a narrow inside and a wide outside condition. An obliquely disposed arc groove 215 is formed on the inner side wall of each through groove 214. Two ends at the flattened inner side are respectively opened with a joining through groove 216 communicating toward the outside.

(14) An external side surface of the second protection seat 22 is also a circle arc cone having a narrow front and a wide rear condition, while an inner side is also a flattened shape. A bottom of the flattened inner side is an opening 221. Two end inner sides of the opening 221 are respectively protruded to form joining protrusions 222. The opening 221 is formed with a set of arc grooves 225 obliquely disposed on the wall surface of the flattened inner side after extending a small section toward the top portion. Two ends of the flattened inner side are respectively disposed with a joining through groove 226 communicating toward the outside. The opening 221 of the second protection seat 22 corresponds to the opening 211 of the first protection seat 21. The position and size of the joining protrusion 222 of the second protection seat 22 corresponds to the joining cavity 212 of the first protection seat 21. The arc groove 225 of the second protection seat 22 is symmetric with the arc groove 215 of the first protection seat 21 by spacing an interval. The joining through groove 226 of the second protection seat 22 corresponds to the joining through groove 216 of the first protection seat 21.

(15) While assembling, the flattened inner side of the second protection seat 22 is pasted to the flattened inner side of the first protection seat 21 to co-form a circle cone body having a narrow front and a wide rear condition as shown in FIGS. 5, 6 and 7. In the process, the joining protrusion 222 of the second protection seat 22, one by one, exactly enters in the joining cavity 212 of the first protection seat 21, and a circle opening is formed by co-surrounding the opening 221 of the second protection seat 22 and the opening 211 of the first protection seat 21 as shown in FIG. 6. At the same time, the cross bar 213 of the first protection seat 21 exactly leans against the flattened inner side of the second protection seat 22 as shown in FIG. 5. Moreover, the joining through groove 216 of the first protection seat 21 correspondingly penetrates through the joining through groove 226 of the second protection seat 22. Accordingly, a set of male joining members 23 (screws for example) is joined with a set of female joining members 231 (nuts for example) after passing through the joining through grooves 226, 216, so that the first protection seat 21 and the second protection seat 22 are assembled to form a complete cord protector 2.

(16) The cord protector 2 is specifically designed to combine with a cord 14 and to protect the cord 14. With reference to FIGS. 8 and 9, before the cord protector 2 is not joined with the female joining members 231 (nuts for examples) through the male joining members 23 (screws for example), the collar 17 outside the cord 14 can be co-clamped by the opening 211 of the first protection seat 21 and the opening 221 of the second protection seat 22. The outermost end head of the cord 14 revolves to fasten the cord 14 through the collar 17 after normally passing through a joining perforation 161 at the tail end of a hook head 16, and the hook head 16 is located at the front end of the cord 14. Accordingly, the opening 211 of the first protection seat 21 and the opening 221 of the second protection seat 22 exactly co-clamp the collar 17. At the same time, the cross bar 213 of the first protection seat 21 passes through a revolving combination place of the cord 14, so that cord bodies of the cord 14 at two sides respectively enter in the two through grooves 214 of the first protection seat 21 after revolving. If the cord body of the cord 14 is in a larger wide condition, it is co-supported and clamped by the arc groove 215 of the first protection seat 21 and the arc groove 225 of the second protection seat 22. After completing the motion of co-clamping the collar 17 through the first protection seat 21 and the second protection seat 22 and enabling the cross bar 213 of the first protection seat 21 passing through the revolving combination place of the cord 14, the male joining members 23 (screws for example) are joined with the female joining members 231 (nuts for example), such that the first protection seat 21 and the second protection seat 22 are not only assembled as the complete cord protector 2 but also combined with the cord 14 to protect the cord 14.

(17) With references to FIGS. 8 and 9, the cord protector 2 disclosed by the invention is combined with the revolving combination place of the cord 14, and the outermost end of the cord 14 would pass through the joining perforation 161 at the tail end of a hook head 16 to achieve combination. The cord 14 is also combined on other appliances. Herein taking the cord 14 combined to the power winch as an example, by comparing with two types of installing cord on the conventional power winch shown in the foregoing FIGS. 1 and 2, with reference to FIGS. 10 and 11, FIG. 10 is in contrast with the foregoing FIG. 1. The cord 14 performs a motion of discharging or withdrawing via the cable entry 151 of a discharging seat 15. However, the revolving combination place of the cord 14 shown in FIG. 10 is further combined with the cord protector 2 disclosed in the invention. FIG. 11 is in contrast with the foregoing FIG. 2. The cord 14 carries out a motion of discharging or withdrawing via the cable entry 181 of a four-way roller set 18. The revolving combination place of the cord 14 shown in the FIG. 11 is also combined with the cord protector 2 disclosed in the invention.

(18) With reference to FIGS. 10 and 11, after the revolving combination place of the cord 14 of the power winch is combined with the cord protector 2 disclosed by the invention, the cord protector 2 collides with the discharging seat 15 or the four-way roller set 18 when the cord 14 is withdrawn via power. Therefore, the loud noise generated from collision between metals in the prior art has been basically eliminated to have the following efficacies:

(19) 1. Since the cord protector 2 is made of flexible material resisting impact, every impact force on the discharging seat 15 or the four-way roller set 18 will be absorbed and buffered by the cord protector 2 to protect the hook head 16, the discharging seat 15 or the four-way roller set 18, so that an industrial safety issue can be prevented from occurring to protect the operator.

(20) 2. While retracting the cord 14, the cord protector 2 is fastened between the hook head 16 and the discharging seat 15 or between the hook head 16 and the four-way roller set 18 to avoid direct contact between metals. Therefore, it can eliminate generated noise during vehicle idling, such that the emotion of persons in the vehicle will not be influenced.

(21) 3. While retracting the cord 14, the cord protector 2 is fastened between the hook head 16 and the discharging seat 15 or between the hook head 16 and the four-way roller set 18 to avoid direct contact between metals. Therefore, it can protect completeness of each component of the power winch and operation accuracy.

(22) The cord protector 2 disclosed by the present invention has a feature of preventing collision between combined rigid components to protect the combined rigid components and operating users to achieve progressive effect of use safety.

(23) While the present invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
