Abstract
The utility model belongs to the technical field of the dumbbell connecting piece, specifically the novel dumbbell connecting piece of a firm connection dumbbell. The utility model discloses a dumbbell nut and inside lining formula packing ring, active the connection in the inboard of dumbbell nut of inside lining formula packing ring, dumbbell nut front end inboard is provided with interior annular structure, dumbbell nut front end inner wall of the port locates to be provided with the recess, inside lining formula packing ring be provided with the breach structure. The utility model discloses dumbbell nut and the cooperation of inside lining formula packing ring are connected, and through tightening the dumbbell nut, inside lining formula packing ring pushes with the dumbbell piece, and the shrink of inside lining formula rubber packing ring becomes the normal pressure to the dumbbell rod, make the dumbbell nut not take place to come off under the effect of two -way atress. Outer loop bead structure and the inboard inner ring slot combination that sets up of dumbbell nut front end that inside lining formula packing ring set up are connected for the dumbbell piece is more firm with being connected of dumbbell pole.
Description
Technical field
The utility model belongs to dumbbell connector technical field, specifically a kind of Novel dumbbell connector of firm connection dumbbell.
Background technology
Dumbbell is common physical fitness equipment, and dumbbell plate of the prior art is placed directly into the relevant position of dumbbell bar.In use procedure, the connection of dumbbell plate and dumbbell bar is not very firm, and dumbbell plate is easy to come off, and causes the personal injury of user.Therefore, need technical progress, structural improvement, make the connection of dumbbell plate and dumbbell bar more firm, ensure use safety.
Utility model content
The purpose of this utility model solves deficiency of the prior art, provides a kind of Novel dumbbell connector of firm connection dumbbell.
The utility model comprises dumbbell nut and lined packing ring, described lined packing ring activity is connected to the inner side of dumbbell nut, dumbbell nut leading inside is provided with inner groove structure, and dumbbell nut front-end port inwall place is provided with groove, and described lined packing ring is provided with gap structure.
Preferably, described dumbbell nut leading inside diameter is 20-40mm; Dumbbell nut middle-end inside diameter is 16-36mm; Dumbbell nut back end inside diameter is 12-32mm.
Preferably, described lined gasket diameters is 16-36mm.
Preferably, the outer shroud fin structure that the arranged outside of described lined packing ring has the inner groove arranged with dumbbell nut leading inside to match to be connected.
Preferably, described lined packing ring is made up of elastomeric material.
The utility model dumbbell nut and lined packing ring are connected, and by tightening dumbbell nut, lined packing ring and dumbbell plate extrude, and lined rubber washer shrinks and forms normal pressure to dumbbell bar, and dumbbell nut is not come off under bidirectional stress effect.The outer shroud fin structure that lined packing ring is arranged and the inner groove that dumbbell nut leading inside is arranged are connected, and make the connection of dumbbell plate and dumbbell bar more firm.In addition, the utility model manufacturing cost is not high, and structure is simple, and practical, the utility model is adapted at correlative technology field and applies.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail, which show preferred embodiment of the present utility model, should be appreciated that those skilled in the art can revise the utility model described here and still realize advantageous effects of the present utility model.Therefore, following description is appreciated that extensively knowing for those skilled in the art, and not as to restriction of the present utility model.
In order to clear, whole features of practical embodiments are not described.They in the following description, are not described in detail known function and structure, because can make the utility model chaotic due to unnecessary details.Will be understood that in the exploitation of any practical embodiments, a large amount of implementation detail must be made to realize the specific objective of developer, such as, according to regarding system or the restriction about business, change into another embodiment by an embodiment.In addition, will be understood that this development may be complicated and time-consuming, but be only routine work to those skilled in the art.
For making the purpose of this utility model, feature becomes apparent, and is further described below to detailed description of the invention of the present utility model.
As in Fig. 1, the utility model comprises dumbbell nut 1 and lined packing ring 2, described lined packing ring 2 activity is connected to the inner side of dumbbell nut 1, dumbbell nut 1 leading inside is provided with inner groove structure, dumbbell nut 1 front-end port inwall place is provided with groove, and described lined packing ring 2 is provided with gap structure.
Dumbbell nut 1 leading inside diameter of the present utility model is 20-40mm; Dumbbell nut 1 middle-end inside diameter is 16-36mm; Dumbbell nut 1 rear inside diameter is 12-32mm.Described lined packing ring 2 diameter is 16-36mm.By tightening dumbbell nut 1, lined packing ring 2 and dumbbell plate extrude, and lined packing ring 2 shrinks and forms normal pressure to dumbbell bar, and dumbbell nut 1 is not come off under bidirectional stress effect.
The outer shroud fin structure that the arranged outside of lined packing ring 2 of the present utility model has the inner groove arranged with dumbbell nut 1 leading inside to match to be connected.This structural design makes lined packing ring 2 difficult drop-off, and the connection of dumbbell plate and dumbbell bar is more firm.
Lined packing ring 2 of the present utility model is made up of elastomeric material, and fastening effect is better.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model embodiment.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the utility model embodiment, can realize in other embodiments.Therefore, the utility model embodiment can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., within the protection domain that all should be included in the utility model embodiment.
