Abstract
The utility model relates to a threaded connection uses novel locking device, including screw element, locking cardboard, static relatively and fastener, to be the non - cylindrical or non -circular the end of screw element, the locking cardboard on be provided with the hole, the end joint of screw element including downthehole, the locking cardboard pass through fastener and fastening connection static relatively, static relatively static relatively with the screw element. The utility model discloses an at the end position of screw element or the outer suit locking cardboard of nut that matches, the locking cardboard blocks the end position of screw element or the nut that matches, makes it rotate, and then through the fastener with locking cardboard fastening connection arrive with the static relatively spare part of screw element on to prevent under the condition of not destroying the screw element that the screw element is not hard up, realize locking purpose.
Description
technical field:
The utility model relates to the screw threads for fastening interconnection technique field in mechanical connection, is specifically related to one and is threaded and uses New anti-loose device.
background technique:
Being threaded is a kind of to be widely usedly dismountablely fixedly connected with, have structure simple, connect the advantages such as reliable, mounting or dismounting are convenient.But in actual use, under being threaded in mechanical shock, vibration or varying load effect, or when temperature variation is larger, being threaded and likely loosening, cause connecting and not firmly even to throw off, easily cause the accident.Therefore, corresponding locking thread measure must be taked when design is threaded.
At present, common locking thread measure can be divided into according to its working principle that friction is locking, machinery is locking, it is locking etc. to destroy screw pair.Rubbing locking is by increasing frictional force, and locking pin, pad or the wire of mainly relying on of machinery realizes locking object by stuck for nut, utilize cotter pin locking or wire to be linked together by one group of screw member head mutually to retrain, cotter pin locking needs on threaded piece, arrange the pin-and-hole installing cotter pin, screw member head is connected constraint mutually by wire, general needs punch at screw member head or on nut, for installing wire, these two kinds of anti-loose methods all double thread part cause certain destruction.And destroy screw pair locking to be after bolton connects, screw pair is destroyed, thus reach and prevent nut from reversing, realize locking object.
model utility content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides one and is threaded and uses New anti-loose device, it is at the position, termination of threaded piece or the nut overcoat dress stop clamp that matches, the position, termination that stop board lives threaded piece or the nut matched, it is made to rotate, and then by fastening piece, stop clamp is fastenedly connected with on the component of threaded piece geo-stationary, thus prevent threaded piece from loosening when not destroying threaded piece, realize locking object.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
One is threaded and uses New anti-loose device, wherein: comprise threaded piece, stop clamp, geo-stationary part and fastening piece, the termination of described threaded piece is non-cylindrical or non-circular, described stop clamp is provided with endoporus, the termination of described threaded piece is connected in endoporus, described stop clamp is fastenedly connected by fastening piece and geo-stationary part, described geo-stationary part and threaded piece geo-stationary.
Further, described endoporus is rectangular opening, or is the elongated hole of two ends circular arc intermediate rectangular.
The beneficial effects of the utility model are:
1, the utility model is at the position, termination of threaded piece or the nut overcoat dress stop clamp that matches, the position, termination that stop board lives threaded piece or the nut matched, it is made to rotate, and then by fastening piece, stop clamp is fastenedly connected with on the component of threaded piece geo-stationary, thus prevent threaded piece from loosening when not destroying threaded piece, realize locking object.
2, the utility model structure simple, easy to use, conceive novel, with low cost, applied range, can be used in separately the locking of a threaded piece, also can be used for the locking of multiple threaded piece group, its difference is only hole bit quantity and shape on the number processing stop clamp according to threaded piece.
3, stop clamp of the present utility model is stamping part, low cost of manufacture; Do not have particular/special requirement for installing space, stop clamp can punching press or bending, and easier for installation, assembling form is various.
accompanying drawing illustrates:
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
embodiment one
As shown in Figure 1, one is threaded and uses New anti-loose device, comprise threaded piece 1, stop clamp 2, geo-stationary part 3 and fastening piece 4, the termination of described threaded piece 1 is non-cylindrical or non-circular, threaded piece 1 in the present embodiment is hexagon head bolt, described stop clamp 2 is provided with endoporus 5, endoporus 5 is the elongated hole of two ends circular arc intermediate rectangular, the termination of described threaded piece 1 is connected in endoporus 5, described stop clamp 2 is fastenedly connected by fastening piece 4 and geo-stationary part 3, described geo-stationary part 3 and threaded piece 1 geo-stationary.The utility model be used for two hexagon head bolts locking.
After hexagon head bolt is threaded with static element, stop clamp 2 is sleeved on the termination of hexagon head bolt, finally by screw, stop clamp 2 and static element is fastenedly connected again.The endoporus 5 of stop clamp 2 blocks the termination of hexagon head bolt, is that the termination of hexagon head bolt can not be rotated in the endoporus 5 of stop clamp 2.
embodiment two
As shown in Figure 2, repeat embodiment one, have following difference, the present embodiment is applicable to the locking connection of three threaded pieces 1 group.
In addition, the shape of the endoporus 5 of stop clamp 2 of the present utility model can also make the shape of rectangular opening, as long as endoporus 5 can block termination or the nut of threaded piece 1, termination or nut cannot be rotated.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
