The specific embodiment
Understand for technology contents of the present utility model, characteristics and effect being had more specifically, existing in conjunction with illustrated embodiment, details are as follows:
Consult Fig. 1 to 3, the automatic opening-closing of a kind of drawer that the utility model first embodiment provides, suitable being assembled on the fixed rack 11 and slip slide rail 12 of drawer, this automatic opening-closing mainly is made up of a drivening piece 50, a body 20, a slide block 30 and a spring 40, wherein:
Drivening piece 50 takes shape in this slip slide rail 12, and this drivening piece 50 has a drive portion 51.
The above is the structure and the configuration explanation thereof of the utility model first each main member of embodiment.
As for the utility model first embodiment make flowing mode and effect thereof, be described as follows.
Please consult shown in Figure 3 again, when the utility model automatic opening-closing carries out closing motion, be located at the drivening piece 50 of slip slide rail 12, first protuberance 31 of its drive portion 51 pushing and pressing slide blocks 30, and make this slide block 30 towards the second hole section, the 212 direction displacements that deviate from cylindrical void 21, at this moment, first projection 33 of this slide block 30 is by the last guiding face 231a guiding of outer ring surface 232 with the inner ring surface 231 of ring groove 23, the backstop of ring groove 23 outer ring surfaces 232 (its state as shown in Figure 4), the pulling force of spring 40, the guiding of protuberance 234 upper surfaces and the guiding of first 231b, the projection 33 of winning is finally fastened in recess 233 (its state as shown in Figure 5), at this moment, because slip slide rail 12 as when desiring the second hole section, 212 directions pulling towards cylindrical void 21, the drive portion 51 of drivening piece 50 can be subject to slide block 30 second protuberances, 32 backstops and can't pull back, use the closing motion of finishing this automatic opening-closing, make the drawer body (not showing on the figure) that is locked on the slip slide rail 12 to open.
Please consult shown in Figure 5 again, when when the utility model automatic opening-closing is closed, carrying out breakdown action, be located at the drivening piece 50 of slip slide rail 12, first protuberance 31 of its drive portion 51 pushing and pressing slide blocks 30, and make this slide block 30 towards the second hole section, the 212 direction displacements that deviate from cylindrical void 21, at this moment, first protuberance 31 of slide block 30 is broken away from recess 233 by second 231c guiding of ring guide groove 23 inner ring surfaces 231, and then by the guiding of protuberance 234 lower surfaces, the backstop (its state as shown in Figure 6) of ring guide groove 23 outer ring surfaces 232, the outer ring surface 232 of the pulling force of spring 40 and ring guide groove 23 returns to initial position (its state as shown in Figure 3) with the following guiding face 231d guiding of inner ring surface 231, uses the action that open the back of closing of finishing this automatic opening-closing.
What deserves to be explained is, when slide block 30 returns to initial position, second projection 32 of slide block 30 is the second hole section 212 that is positioned at this body 20, and because the second hole section 212 and the first hole section 211 are a bending angle, therefore, slide block 30 can be axle center and beat one angle clockwise with its first projection 33, make second projection 34 to top offset one distance, allow the drive portion 51 of second projection 34 and drivening piece 50 not on same horizontal line, at this moment, 50 of drivening pieces break away from slide block 30 fully, make the drawer body that is locked on the slip slide rail 12 be opened (not showing on the figure).
See also shown in Fig. 5,7, when the utility model automatic opening-closing is closed, it is spurred by force, the drive portion 121 that is located at the drivening piece 50 of slip slide rail 12 pushes against second protuberance 32 of slide blocks 30, and because first projection 33 of slide block 30 fastens the recess 233 in body 20, therefore drivening piece 50 can't drive the second hole section 212 direction displacements of slide block 30 towards cylindrical void 21, drivening piece 50 will continue to bestow second protuberance 32 1 pulling force of direction left by its drive portion 51, allow second projection 34 of slide block 30 produce a thrust that makes progress simultaneously.
And between thrust that second projection 34 is produced is greater than body 20 cylindrical voids 21 and distortion hole 22 during the structural strength at position, 22 in hole of distortion is subjected to second projection, 34 extruding of slide block 30 and is out of shape, at this moment, slide block 30 can be axle center and beat one angle clockwise with its first projection 33, make second protuberance 32 to top offset one distance, after moving on second protuberance 32 with the drive portion 51 of drivening piece 50 not on same horizontal line, 12 of slip slide rails can break away from slide block 30 (its state as shown in Figure 8) smoothly, make that the drawer body (figure on do not show) of locking on this slip slide rail 12 opened.
In view of the above, this automatic opening-closing more can reach when drawer sliding rail is closed condition except can opening and closing automatically through pushing, the purpose that can not cause this slide rail or automatic opening-closing to damage after haling.
Consult Fig. 9 and 10, the automatic opening-closing of a kind of drawer that the utility model second embodiment provides, it is made up of a drivening piece 61, a body 62, a slide block 63 and a spring 64 equally, because its configuration, mode of operation and purpose are same as first embodiment, so do not giving unnecessary details at this, be as for second embodiment and the first embodiment difference:
Automatic opening-closing is suitable for and is assembled on drawer body 71 and the drawout cubicle 72.Wherein drivening piece 61 is located at this drawer body 71 lateral surfaces, and has a drive portion 611 equally; And body 62 is fixedly arranged on the medial surface of this drawout cubicle 72, and comprise a cylindrical void 621, contiguous these cylindrical void 621 tops equally and be squeezed and the distortion hole 622, a ring guide groove 623 that is communicated with this cylindrical void 621 and the card division 624 that are out of shape, by this, when this drawer is when being in closing state, hale this drawer body 71 this drawer body 71 or self closing device are damaged, use another feasible enforcement state of reaching.
In sum, above-mentioned two embodiment and diagram only are preferred embodiment of the present utility model, can not only limit practical range of the present utility model with this, promptly every equalization of being done according to the utility model claim changes and modifies, and all should belong in the scope that the utility model patent contains.
