Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
It is explicitly described.
Embodiment 1
Because existing slide rail is in the absence of the structure of rail in can locking so that three section slide rails can move easily in use
Position, it is rather inconvenient.
Fig. 1-2 is referred to, in order to solve the above-mentioned technical problem, present embodiment discloses a kind of cunning with self-locking structure
Rail, it includes outer rail 10, middle rail 20 and interior rail 30, between outer rail 10 and middle rail 20 and between middle rail 20 and interior rail 30
It is provided with the pearl nest (not indicated in figure) with ball.
Refer to Fig. 3-4, on outer rail 10 formed with confession in rail 20 slide chute 11, formed on the bottom surface of chute 11
There is the arrow-shaped parallel and raised with bottom surface to fix fixture block 12, the shrinkage direction of pointing direction rail 20 in of arrow is fixed
The two side of fixture block 12 and chute 11 is equidistantly positioned.
Fig. 5-6 are referred to, the cross sectional shape of middle rail 20 is located at chute 21 respectively in bow font formed with chute 21 and two
The chute 22 of both sides.Chute 21 is oppositely arranged with chute 11, and when being slided between middle rail 20 and chute 11, chute 21 is fixing card
Block 12 provides sliding space；Chute 22 is set backwards to chute 11, and chute 22 is that interior rail 30 provides sliding space.
Fig. 5 is referred to, it is rotatable on the back side of chute 21 to be provided with rotating card block 23.Rotating card block 23 includes fixing end
231 and fastening end 232, fixing end 231 be fixed on by rivet 233 on the back side of chute 21, make rotating card block 23 can be with riveting
Nail 233 is that the center of circle rotates, and fixing end 231 is consistent with the shrinkage direction of middle rail 20 with the line direction of fastening end 232.
Through hole 24 is further opened with chute 21, the card that through hole 24 is stretched into chute 21 is formed through in fastening end 232
Flanging 234 is closed, the quantity of the engaging flanging 234 is two, and the respectively both sides of fastening end 232, in two engaging flangings 234
Any one can be fastened on arrow-shaped and fix in two flanks that fixture block 12 is formed on corresponding straight flange 121, rail 20 is fixed in order
On outer rail 10.
Fig. 8 is referred to, formed with two side arms 31 on interior rail 30, formed with chute 32, chute 32 between two side arms 31
Tip upside down on rail 20, two side arms 31 are slided in two chutes 22 of middle rail 20.
During the use for the slide rail that this has self-locking structure, after middle rail 20 stretches, the rotating card block 23 on middle rail 20
It can be moved with middle rail 20, now the moving direction of rotating card block 23 is the direction opposite with the arrow of the fixed formation of fixture block 12,
The engaging flanging 234 of rotating card block 23 can move along the hypotenuse of fixed fixture block 12, refer to Fig. 1, when engaging flanging 234 moves
When on to the straight flange 121 of fixed 12 liang of flanks of fixture block, rotating card block 23 can be fallen on the straight flange 121, and rotating card block 23 is stuck in
On the straight flange 121, and then the technique effect for preventing middle rail 20 from bouncing back, even if middle rail 20 reaches the effect of self-locking, in order to true
Protecting rotating card block 23 can accurately fall on straight flange 121, the installation direction of above-mentioned slide rail can not be it is horizontal positioned, need to be with level
Direction is angled, makes rotating card block 23 to reach the effect of self-locking under gravity.Centering rail 20 is needed to unlock
When, rotating card block 23 is toggled it to the position parallel with middle rail 20, rotating card block 23 is departed from the fixation fixture block 12 of outer rail 10 i.e.
The unblock of rail 20 in can completing.
Embodiment 2
Present embodiment discloses a kind of slide rail with self-locking structure, and it includes outer rail 10, middle rail 20 and interior rail 30.Equally
It is rotatable on the back side of the chute 21 of middle rail 20 formed with sagittate fixed fixture block 12 on the bottom surface of chute 11 of outer rail 10
Provided with rotating card block 23.
Refer to Fig. 5, as the further improvement of technical scheme, the present embodiment as different from Example 1, in revotating card
The both sides of block 23 are oriented to direction and the fixing end 231 of flanging 235 and engaged backwards to flanging 234 is engaged formed with flanging 235 is oriented to
The line direction at end 232 is consistent.
The width that two of which is oriented between flanging 235 is less than the width of the chute 32 of interior rail 30 so that interior rail 30 is in
When being slided on rail 20, two are oriented to flanging 235 and can slide into the chute 32 of interior rail 30, and being oriented to flanging 235 when two slides into interior rail
When in 30 chute 32, it is oriented to flanging 235 and causes rotating card block 23 to produce rotary arm, rotating card block 23 can be rotated as chute
32 parallel directions, the straight flange 121 for causing rotating card block 23 to depart from 12 liang of flanks of fixed fixture block is carried out, and then make it that middle rail 20 is de-
From the locking of fixed fixture block 12, said process can be completed during interior rail 30 shrinks and slided, and reach the skill of automatic unlocking
Art effect.
Embodiment 3
Present embodiment discloses a kind of slide rail with self-locking structure, and it includes outer rail 10, middle rail 20 and interior rail 30.Equally
It is rotatable on the back side of the chute 21 of middle rail 20 formed with sagittate fixed fixture block 12 on the bottom surface of chute 11 of outer rail 10
Provided with rotating card block 23.
Fig. 7-8 are referred to, as the further improvement of technical scheme, the present embodiment is unlike the embodiments above,
The end set limited location part 25 of middle rail 20, the chute 251 that limiting component 25 slides formed with the interior rail 30 of two confessions, wherein
Formed with the fixture block 252 in the chute 32 that can extend into interior rail 30 on the madial wall of one chute 251.In the chute 32 of interior rail 30
It is interior to be provided with elastic clamping block 33, close to the side of side wall formed with neck 331, the fixture block of limiting component 25 on elastic clamping block 33
252 can be fastened in neck 331.Wherein elastic clamping block 33 is elastic component, and elastic component 33 is rotatably arranged interior rail by rivet 332
In 30 chute 32, shrinkage direction of the rivet 332 towards interior rail 30.
When interior rail 30 is stretched to most long status, said structure causes fixture block 252 to be fastened on the neck 331 of elastic component 33
On, because rivet 332 is towards the shrinkage direction of interior rail 30, when interior rail 30 continues to stretch outward, neck 331 prevents fixture block 252
Continue to move to, reach spacing effect, and when interior rail 30 needs retraction, interior rail 30 is enforced, elastic component 33 can produce
Deformation, and cause fixture block 252 to depart from the neck 331 on elastic component 33.The structure causes interior rail 30 to possess lock function.
Embodiments described above, the restriction to the technical scheme protection domain is not formed.It is any in above-mentioned implementation
Modifications, equivalent substitutions and improvements made within the spirit and principle of mode etc., should be included in the protection model of the technical scheme
Within enclosing.
