Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 to Fig. 4, a kind of nut locking device 100 that Fig. 3 and Fig. 4 provides for the utility model preferred embodiment, they some second locking teeths 120 comprising some first locking teeths 110 and coordinate with some first locking teeths 110.First locking teeth 110 and/or the second locking teeth 120 are made up of the material (as plastics) of elastically deformable.Above-mentioned nut locking device 100 is applied to photovoltaic connector 10, and the connection reliability between the plug 11 of photovoltaic connector 10 and nut 12 is strengthened further.Be described further for photovoltaic connector 10 and nut locking device 100 below.
Please refer to Fig. 1 and Fig. 2, one end of plug 11 is provided with outside thread, and nut 12 is provided with the internal thread coordinated with described outside thread, is threaded connection and makes to be connected and fixed between plug 11 and nut 12.
Please refer to Fig. 3 and Fig. 4, plug 11 is also provided with a ratchet (sign), some first locking teeths 110 are along the circumferential direction arranged on this ratchet, have an accepting groove 111, first locking teeth 110 and be positioned at the externally threaded inner side of plug 11 between adjacent two the first locking teeths 110.Please refer to Fig. 2 to Fig. 4, the inner side surface of nut 12 is provided with the internal thread coordinated with plug 11 outside thread, and some second locking teeths 120 are distributed in the inner side surface of nut 12 and are positioned at the front end of internal thread.The random inner side surface being distributed in nut 12 of some second locking teeths 120.Like this, after nut 12 is assemblied in plug 11, namely complete after being threaded between nut 12 with plug 11, a part second locking teeth 120 on nut 12 is not contained in plug 11 accepting groove 111, another part second locking teeth 120 on nut 12 to be contained in plug 11 accepting groove 111 and to engage with the first locking teeth 110, thus ensures nut 12 and the reliability be connected between plug 11.By the random distribution in nut 12 of the second locking teeth 120, avoid nut 12 after being assembled to plug 11, in nut 12, the second locking teeth 120 is not all contained in the situation of plug 11 accepting groove 111.Need to further illustrate, the quantity of the second locking teeth 120 is less than the quantity of the first locking teeth 110, and the quantity of the second locking teeth 120 is at least two.Second locking teeth 120 of Fig. 3 display is three, and Fig. 4 shows that the second locking teeth 120 of display is four.
In addition, the first locking teeth 110 is provided with guiding surface 112 and the stop surface 113 relative with guiding surface 112.The supporting surface 122 that second locking teeth 120 is also provided with a guiding surface 121 and can abuts against with the stop face 113 of plug locking teeth 110.
Please refer to Fig. 2 to Fig. 4, plug 11 and nut 12 are in assembly process, and plug 11 and nut 12 first carry out screw-thread fit and be fixedly connected with nut 12 to make plug 11.When nut 12 and plug 11 be threaded soon complete time, second locking teeth 120 can contact with the first locking teeth 110, under the leading role of the guiding surface 121,112 of the second locking teeth 120, first locking teeth 110, can be there is certain deformation in the first locking teeth 110 and/or the second locking teeth 120, such second locking teeth 120 can cross the first locking teeth 110.Nut 12 is rotated further, until nut 12 is rotated in place, after namely the two completes and is threaded.Part second locking teeth 120 in nut 12 is contained in plug 11 accepting groove 111, and the supporting surface 122 of this part second locking teeth 120 is held in the stop surface 113 of the first locking teeth 110, and namely part second locking teeth 120 and the first locking teeth 110 engage each other.Like this, if nut 12 rotates backward, because the supporting surface 122 of the second locking teeth 120 contacts with the stop surface 113 of the first locking teeth 110, the second locking teeth 120 is prevented to cross the first locking teeth 110, also just prevent nut 12 to continue to rotate backward, thus achieve locking functions.
In the utility model embodiment, the first locking teeth 110 on plug 11 can exchange with the second locking teeth 120 on nut 12, namely the first locking teeth 110 in nut locking device 100 also can be arranged on nut 12, the second locking teeth 120 in nut locking device 100 also can be arranged on plug 11, repeats no more for above-mentioned nut locking device herein.
The utility model provides a kind of nut locking device, owing to engaging each other with the first locking teeth 110 in the accepting groove 111 that part second locking teeth 120 in nut 12 is contained in plug 11, produce enough locking power thus, like this, even if the second locking teeth 120 of remaining part fails to engage in described accepting groove 111, still part second locking teeth 120 engaging into accepting groove 111 can be relied on to provide anti-loosing effect, nut 12 is not easily come off from plug 11, therefore, it is simple that the nut locking device that the utility model provides has structure, connection reliability is high, the advantage that anti-loosing effect is good.
Above-described instantiation; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
