Abstract
The utility model discloses a kind of disconnecting prevention structure for key buckle ring, comprise I-shaped nut and anticreep pin, described I-shaped nut comprises nut extension and connected hollow screw, the free end inwall of hollow screw is provided with one section of internal thread, the free end outer setting of hollow screw has a circle anticreep protuberance, the external diameter of anticreep protuberance is less than the external diameter of nut extension, hollow screw outside between anticreep protuberance and nut extension forms the anticreep groove plugged for anticreep pin, and the height of described anticreep groove is greater than the diameter of anticreep pin; The utility model structure is simple, reasonable in design, by arranging anticreep protuberance and anticreep groove on the basis of conventional screw cap, coordinate anticreep pin, effectively can ensure that nut can not come off from key buckle ring, longer service life, engulfs the parts dropped when can effectively avoid child to play simultaneously accidentally, safer.
Description
Technical field
The utility model relates to a kind of clasp accessory, specifically a kind of disconnecting prevention structure for key buckle ring.
Background technology
Number of patent application is 201320628596.0, patent name is disclose a kind of key buckle ring in the patent of key buckle ring, mainly comprise secure component, locking member and elastomeric element, its secure component is the female plain nut of a tool, this fastening structure poor effect, easy loose or dislocation, on the one hand, once this secure component comes off after loss, whole key buckle ring cannot use, and cause shorten the service life of key buckle ring; On the other hand, if having child in user family, this secure component is easily at play in process by child and accidentally screws out, and there is the potential safety hazard that child engulfs tiny parts by mistake; For these reasons, be necessary to improve the structure of key buckle ring, to adapt to user demand.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, difficult drop-off, and the disconnecting prevention structure for key buckle ring that can effectively lock, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of disconnecting prevention structure for key buckle ring, comprise I-shaped nut and anticreep pin, described I-shaped nut comprises nut extension and connected hollow screw, the free end outer setting of hollow screw has a circle anticreep protuberance, and the hollow screw outside between anticreep protuberance and nut extension forms the anticreep groove plugged for anticreep pin.
As further program of the utility model: the free end inwall of described hollow screw is provided with one section of internal thread.
As the utility model further scheme: the external diameter of described anticreep protuberance is less than the external diameter of nut extension.
As the utility model further scheme: the height of described anticreep groove is greater than the diameter of anticreep pin.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by arranging anticreep protuberance and anticreep groove on the basis of conventional screw cap, coordinate anticreep pin, effectively can ensure that nut can not come off from key buckle ring, longer service life, accidentally engulf the parts dropped when can effectively avoid child to play simultaneously, safer.

Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-4, a kind of disconnecting prevention structure for key buckle ring, comprise I-shaped nut 1 and anticreep pin 2, described I-shaped nut 1 comprises nut extension 4 and connected hollow screw 9, the free end inwall of hollow screw 9 is provided with one section of internal thread, the free end outer setting of hollow screw 9 has a circle anticreep protuberance 5, the external diameter of anticreep protuberance 5 is less than the external diameter of nut extension 4, hollow screw 9 outside between anticreep protuberance 5 and nut extension 4 forms the anticreep groove 6 plugged for anticreep pin 2, the height of described anticreep groove 6 is greater than the diameter of anticreep pin 2.
Operation principle of the present utility model is: when using the utility model, hollow screw 9 is inserted in one end of double-threaded screw 7, and achieved a fixed connection by the internal thread of its inwall, then I-shaped nut 1 is plugged into clasp main body 3 from side, install movable part 8 at the opposite side of clasp main body 3, movable part 8 is connected with the other end of double-threaded screw 7; Inserted in clasp main body 3 by the pin hole in clasp main body 3 anticreep pin 2, anticreep pin 2 is positioned at anticreep groove 6, due to the barrier effect of anticreep protuberance 5 and anticreep groove 6, thus can effectively prevent I-shaped nut 1 from coming off from clasp main body 3.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
