Abstract
The utility model relates to an improved structure of slide rails of a drawer, which comprises an outer slide rail, a stop block, an inner slide rail and a steel ball slide blade. Both positioning blocks on the stop block are respectively upwards extended from the outer margin thereof with a clamping piece which is connected with the front end faces of two blocking posts. The two clamping pieces are preset with circular-arc-shaped convex clamps which can be led into clamping grooves which are preset on both sides of the steel ball slide blade and the two clamping pieces are thick properly. Gaps are formed respectively between the outer side face of one clamping piece and one side of an adjacent slide rail and between the outer side face of the other clamping piece and the other side of the adjacent slide rail. Therefore, abrasion can be reduced, and the service life of the utility model is prolonged relatively.
Description
The utility model relates to a kind of improvement structure of drawer sliding rail, is holding or break away from structure and improved in addition at its steel ball sheet and stop block.
Same creator's the U.S. the 5th, 577, No. 821 patent cases are shown in Fig. 1～2, it is to can be rated as practicality, improve part and remain to be improved but still have not attain, in the hope of perfection, explanation now as back: since the both sides of stop block 5 block 53,54 convex clips that extend internally respectively 531,541 hold the outermost two ends 921 of the second steel ball slide plate 92 gently, 922 suitable distances, when drawer 10 reinstalls, even the front end 81 of interior slide rail 8 does not keep fully and slide rail 7 parastates in middle level are inserted in, can not push up the card second steel ball slide plate 92 earlier yet and pass forward, thereby avoid drawer 10 can't push back the location even the situation of damaging the second steel ball slide plate 92 takes place; In addition, the convex clip 531,541 of the bumping post 53,54 of aforementioned stop block 5 is wearing and tearing easily through using later on repeatedly contacting of the second steel ball slide plate, 92 outermost two ends 921,922, and make the thickness of each convex clip 531,541 gradually thin, can't more closely contact even lose contact with the outermost both sides 921,922 of the second steel ball slide plate 92 relatively respectively and hold effect, and lose aforesaid function.
Also have, the U.S. the 5th, 722, No. 750 patent cases such as Fig. 3～shown in Figure 4, though its two locating piece 55,56 bottom inside edge has rake 551,561 and slightly have a line of rabbet joint 5511, therefore 5611 and have suitable elasticity and can reduce wear, but it holds still deficiency of locating effect, and because this horizontal direction line of rabbet joint 5511, the 5611st, towards the outermost bottom face both sides 923 of the second steel ball slide plate 92,924, therefore, can cause the second steel ball slide plate, 92 bottom face both sides 923 because of the improper application of force occasionally after using a period of time, 924 bottom surface 9231,9241 snap in the line of rabbet joint 5511,5611 the insides, thereby can't successfully break away from, and then the influence operation is smooth and easy.
So the purpose of this utility model is to provide a kind of improvement structure of drawer sliding rail, hold locating effect and service life to improve it.
The utility model is achieved in that a kind of improvement structure of drawer sliding rail, include external slide rail, middle level slide rail, interior slide rail and chuck at first steel ball slide plate between external slide rail and the middle level slide rail and chuck the second steel ball slide plate between middle level slide rail and interior slide rail, the locking of aforementioned external slide rail is at the drawer space madial wall predetermined position of cabinet, interior slide rail then with the sidewall locking of drawer;
Wherein:
This middle level slide rail, its outer openings end is provided with a stop block, and this stop block convexes with projection, and the both sides, top of this stop block have bumping post in addition in addition, and the set stop block of this middle level slide rail is provided with two locating pieces in addition;
Should in slide rail, be preset with the clip of plastic cement one injection molding, and two locating pieces of this stop block are located at its bottom inside edge, and this two locating piece and respectively extended rake;
Be characterized in:
It is the retaining sheet of a linking two front end faces that block that two locating pieces of this stop block are extended upward by its outer rim respectively, this two retaining sheet is preset with the circular arc convex clip, hold the location mutually with the default draw-in groove in the side of the second steel ball slide plate, and this two retaining sheet has suitable thickness, and its lateral surface forms the gap respectively and between the two side of middle level slide rail.This stop block also can directly be installed in the external slide rail face and omit the middle level slide rail and the first steel ball slide plate, and directly by the drawer space madial wall predetermined position of external slide rail locking at cabinet, and the circular arc convex clip of two locating pieces of this stop block is located at the holding section of its bottom, the draw-in groove default with steel ball slide plate bottom face both sides holds the location mutually, and each retaining sheet is curved arc shape section, and suitably has the line of rabbet joint of two suitable thickness apart from the position in its both sides.
The utlity model has following positive progressive effect:
1, two locating pieces of this stop block are extended upward the retaining sheet of the front end face that is a linking two bumping posts respectively by its outer rim, except increasing and the holding the area of the two sides of steel ball slide plate, further can hold locating effect and improve it in the default draw-in groove in the side that imports the steel ball slide plate by the default circular arc convex clip of this two retaining sheet.
2, two retaining sheets of stop block have suitable thickness, make its lateral surface form the gap respectively and between the two side of adjacent slide rail, make this retaining sheet have preferable elasticity and reduce wearing and tearing with the frictional force that minimizing holds contact, improve service life relatively, and the front end that cooperates this retaining sheet forms the inclined plane, can contact with the two sides of steel ball slide plate more swimmingly to hold or light and successfully break away from the aforementioned positioning states that holds.
