Preferably, the card slot includes at least the first slot position and the second slot position, and first slot position is located at the second slot position
Top is simultaneously connected to the second slot position, and the width of first slot position is greater than the second slot position and is less than one end that kelly is equipped with latch
Width.
Preferably, the card slot also includes third slot position, and the third slot position is located at below the second slot position and with second
Slot position connection, it is in dovetail shaped that third slot position bottom end aperture, which is greater than upper end aperture,.
Preferably, handle is fixed on the fastener.
Compared with prior art, the utility model has the beneficial effects that the utility model is not provided with excessive components,
Only needing to be provided with groove on the screw of existing maturation, then cooperate again " kelly of L " type and fastener be clamped；In order to be formed
Stablize snap effect, the slim card of easy processing can be used in fastener, card hole or card slot is equipped with above it, thus on kelly
Latch carry out teeth clamping, by wedge shape teeth allow slim card to be not easy to loosen, to guarantee that the tail end of kelly is tight
Gu the effect of nut, the utility model is ingenious in design, and the processing is simple, practical.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to,
The utility model provides a kind of technical solution: a kind of screw with locking fastener, including screw rod 1 and nut
2, the screw rod 1 is equipped with the groove 3 of perforation, and activity is sliding in the groove 3 has " kelly 4 of L " type, " kelly 4 one of L " type
End is run through the screw head 5 of screw rod 1 and is clamped with fastener, and the other end of the kelly 4 and the side wall of nut 2 are clamped, after nut 2 is twisted
Be inserted into kelly 4 in groove 3, and make " short side one end of L " type and the clamping of nut 2 limit, other end pass through screw head 5 and with card
Part clamping, which is realized, to be fixed.
The specific fastener is slim card 6, and manufacturing cost is low and installation prevents take up space, and the kelly 4 leans on
One end of nearly slim card 6 is equipped with latch 8, and the kelly 4 is clamped by latch 8 and slim card 6, and slim card 6 can be used
Elastic metallic facilitates latch 8 to be clamped therewith.The form of clamping at least can be two kinds, the first: being provided on the slim card 6
The card hole 7 to match with latch 8；
Second: card slot 9 is equipped on the slim card 6, and the bottom end of the card slot 9 penetrates through slim card 6, it is described
Latch 8 is located at the side of kelly 4, and the latch 8 is wedge shaped, so can slide into slim card 6 from top and block with latch 8
Connect, and latch 8 is due to being clamped direct side and card slot 9 for wedge shape, be allowed to not pull out realize it is locking.
Further, the card slot 9 includes at least the first slot position 901 and the second slot position 902, and first slot position 901
It is connected to above the second slot position 902 and with the second slot position 902, and the width of first slot position 901 is greater than the second slot position 902
And it is less than one end width that kelly 4 is equipped with latch 8, since slim card 6 uses elastic material, so being inserted into card in latch 8
Slight deformation can occur for slot 9, and latch 8 oneself is skidded off and loosened in order to prevent, so doing to design at both ends formula, wherein the first slot position
901 be the position being finally clamped with latch 8, and the width of the first slot position 901 is suitable with the width of 8 low spot of latch on kelly 4,
So 902 width of the second slot position can be narrower relative to latch 8, need when installation to go to fill with putting strength.
Further, this slim card 6 in order to facilitate the installation of, enables latch 8 smoothly to enter in card slot 9, described
Card slot 9 also includes third slot position 903, and the third slot position 903 is located at 902 lower section of the second slot position and connects with the second slot position 902
Logical, it is in dovetail shaped that the 903 bottom end aperture of third slot position, which is greater than upper end aperture,.
Further, it is fixed with handle 10 on the fastener, be easy for installation and removal.
Working principle: screw rod 1 is passed through into the object to be fastened when use, pre-load nut 2 is then screwed on and reaches needs
Position, later by " kelly 4 of L " type slides into groove 3, and makes " short side of L " type against 2 side wall of nut, installs thin later
Type card 6, slim card 6 are clamped with latch 8 from slide downward above latch 8 and realize that position is fixed, pull at when needing to dismantle
Dynamic handle 10, is pullled upwards.The orientation " upper and lower " etc. said in certain the utility model, in actual application not necessarily
It is identical, but as tight clamping fit thus caused by gravity slippage influence very little, and the utility model setting it is recessed
The direction of slot 3 be not it is fixed, most situations are all to install upward in practical application, reduce the influence of gravity to the greatest extent
's.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
