Abstract
The utility model discloses an automatic shut-off device for drawer slide, which comprises a sliding seat, a sliding hook, a sliding block, a spring, a connecting bar arranged in the inner slide; wherein, when the bottom arc block on the bottom of the sliding hook slides to the groove on the bottom surface of the sliding seat, the sliding hook slowly sinks down the back radian of the arc block instead of sinking directly and meanwhile the inclined positioning slot of the sliding hook gradually slides to the guiding block on the bottom surface of the sliding seat at an inclined upward angle, therefore the sliding hook can slide without rapid and obvious sinking and the sliding block in the chute on the two sides of the sliding seat so that the drawer connected with the inner slide can slide rather steadily, the firm position of the inclined positioning slot of the sliding hook and the guiding block on the bottom surface of the sliding seat can avoid that because of the careless impact or collision, earthquakes and other factors the sliding hook separates and slides backward with the sliding block in advance with help of the restore power of the spring so that the automatic shut-off function can be relatively ensured.
Description
Technical field
The utility model relates to a kind of self closing device of drawer sliding rail.
Background technology
The at present general drawer sliding rail 9 that uses as shown in Figure 1 and Figure 2, its self closing device is made of the jacking block 941 of closing seat 91, spring 92, slide block 93 automatically and be positioned on the slide rail 94.Because spring 92 is positioned at the spring storage tank 912 of closing seat 91 automatically, when therefore spring 92 back and forth stretches, the inboard of this spring 92 can with the internal face friction of spring storage tank 912, use a period of time rear spring 92 to be easy to generate the situation of distortion or elasticity attenuation, and when closing seat 91 automatically when being fixed in external slide rail 95 places, if spring 92 damage must pull down when changing more difficult.
In addition, slide block 93 is by two guide pillars 931,932 past polyslips on the chute 911 of closing seat 91 automatically, and the side of chute 911 bending, the clamping groove 9111 that extends and form, can block a guide pillar 931 of above-mentioned slide block 93, yet the guide pillar 931 that causes slide block 93 when the user sorts out a drawer or runs into drawer because of carelessness easily breaks away from the clamping groove 9111 of chute 911, and make slide block 93 break away from and slide onto rear side by means of the strength of spring 92, so that drawer forfeiture automatic closing function when desire pushes back drawer, even can't make drawer push back rear side fully and cause puzzlement to the user, United States Patent (USP) the 5th, 207, No. 781, the 5th, there are above-mentioned shortcoming too in 302, No. 016 and PCT patent WO 01/8279A2 case.
One side of above-mentioned spring 92 is colluded by the outside of guide pillar 931 and is established and back and forth stretched in non-horizontal direction, causes slide block 93 to move and has some setbacks, and spring 92 also is easier in the back damage of using a period of time.And this slide block 93 is directly bigger by the strength that spring 92 retracts, and is easy to generate vibrations, also has some setbacks with respect to the motion of slide block 93.
Summary of the invention
The purpose of this utility model is that above-mentioned prior art medi-spring dismounting is inconvenient, slide rail slides unstable, the unfavorable defective of automatic closing function in order to overcome, and a kind of self closing device of drawer sliding rail is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of self closing device of drawer sliding rail, it includes:
Slide, link fixing with the external slide rail bottom face of this drawer sliding rail, this external slide rail then links by the side locking of another lock member and cabinet madial wall, the other end that the rear side of this slide is provided with draw-in groove and spring colludes the setting position, and this slide is provided with a sliding ditch, the wall of the both sides adjacent symmetric in this cunning ditch is provided with unidirectional chute, and the below of this chute is in abutting connection with a diapire face, and the leading portion of this diapire face symmetry that makes progress extends to form guiding block, and respectively be provided with by low gradually high back guiding incline, end face and preceding abutment face, and the axially parallel of the bottom of this guiding block and diapire face, and this diapire face forms an interval trough in a side of this guiding block, and this interval trough is provided with to the recessed recessed groove of diapire face;
Sliding colluding, a left side, the rear of right both sides respectively is provided with guide pillar, it is hubbed in the set chute of the adjacent wall in both sides in the sliding ditch of this slide, and its front side is provided with the guiding incline to the front lower place inclination, then be provided with detent near the position, intermediate portion, its top rear side is provided with the block in abutting connection with this detent in addition, and the sliding rear side that colludes is provided with the pivot connected slot of downward opening and the pivot of slide block articulates, and the leading portion position that this cunning is colluded is provided with the oblique locating slot that is open state, the shape of this oblique locating slot is roughly corresponding to the shape of the guiding block of the diapire face of this slide, and this oblique locating slot system be inclined upwardly and with axial formation one angle of the diapire face of this slide, the central bottom at this cunning leading portion position of colluding is provided with the arc piece of downward tuck pointing in addition;
Slide block, be slidedly arranged on by its both sides in the chute of these slide both sides, and its both sides are provided with block, and this block extends a hook portion and is connected with a side of spring, opposite side by spring is connected with this slide again, the front side of this slide block forms a groove, and the pivot connected slot of the rear side that formation one pivot and this cunning are colluded in this groove articulates;
Trace, a side of the end face of slide rail in being located in the drawer sliding rail, the inboard of this trace is in abutting connection with slotted eye.
Wherein, this slide can further be provided with a locating slot by being embedded or mode such as locking is installed an oil hydraulic cylinder, and a side in this oil hydraulic cylinder axle center and nested connection of the set caulking groove of slide block.
