Description

The enhancement mode drawer guideway

Technical field

The invention belongs to field of furniture, especially a kind of operation is got up more along sliding drawer guideway.

Background technology

The more piece guide rail is widely used in the drawer of top-grade furniture, modal is three joint guide rails, it is by movable rail, middle rail, retaining rail is formed, movable rail and middle rail, between middle rail and the retaining rail roller or ball are arranged all, (two joint guide rails have only movable rail and retaining rail by the retainer constraint for roller and ball, between movable rail and the retaining rail ball retainer is arranged), because the length of retainer is shorter than the length of slide rail, so the middle relatively rail of movable rail is cantilever beam structures, middle rail relative fixed rail also is cantilever beam structures (movable rail relative fixed rail is cantilever beam structures in the two joint guide rails), load under the weight of object at drawer and drawer, the front end of drawer has a little sinking, especially when drawer is closed fully, the drawer front end that sinks shows that more drawer panel tilts, produce the space above the drawer panel and between the drawer cupboard, destroyed the attractive in appearance of furniture, this is that urgent need is improved.

Summary of the invention

The purpose of this invention is to provide the enhancement mode drawer guideway that a kind of drawer front end can not sink.

The present invention is made up of the above slide rail that slides relatively of two joints, between between the two adjacent joint slide rails retainer is arranged, and wherein the first segment slide rail is connected under the drawer; On second slide rail adjacent with first slide rail one or more support wheels are arranged, support wheel is installed in the second slide rail front end and contacts with the lower plane rolling of first slide rail.

As a further improvement on the present invention, support wheel has one, and it supports wheel carrier by one and is installed on the middle rail; The front end of middle rail has a hole clipping and four spacers, and supporting wheel carrier has two cramps, two locating slots and two semiaxis holes; Support wheel shaft and pass support wheel, its two embeds two semiaxis holes supporting wheel carrier, and two cramps that support wheel carrier are buckled in two edges of hole clipping, and four spacers insert two locating slots that support wheel carrier.

The present invention is simple in structure, and effect is remarkable, and suitable being installed on all three joint guide rails and the two joint guide rails used.

The specific embodiment

The present invention is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, embodiment 1 is a cover three joint guide rails, has first slide rail 1, second slide rail 2 and the 3rd slide rail 3 of punching of the steel plate, and they are equivalent to movable rail, middle rail and the retaining rail of tradition three joint guide rails respectively.There are a plurality of installing holes 16 to be used for the 3rd slide rail 3 is fixed in the drawer cupboard on the facade 15 of the 3rd slide rail 3, drawer is installed on first slide rail 1, between first slide rail 1 and second slide rail 2, second slide rail 2 and the 3rd slide rail 3 roller or ball are arranged all, roller is by retainer constraint (retainer and roller are blocked invisible in the drawings).Different with traditional product is, has one to support wheel carrier 4 at the front end of second slide rail 2, supports on the wheel carrier 4 support wheel 5 is installed, and support wheel 5 is done rolling with the lower plane of first slide rail 1 and contacted.

Referring to Fig. 2, the front end punching out of second slide rail 2 goes out the hole clipping 10 of a rectangle, upwards bends out four spacers 13 on the limit, the left and right sides of hole clipping 10.

Referring to Fig. 3 to Fig. 6, it is made of plastic to support wheel carrier 4, and supporting wheel carrier has two semi-cylindrical semiaxis holes 9 to be used to hold the axle head that supports wheel shaft; Supporting the wheel carrier front and back has two cramp 7 and four locating pins 11 of extending downwards, supports wheel carrier and also has two to be close to plate 12.

Referring to Fig. 7, support wheel shaft 6 and be made of a steel, its diameter of axle is adaptive with the aperture in the semiaxis hole of supporting wheel carrier.

Referring to Fig. 8, support wheel 5 is made of plastic, and its axis hole is slidingly matched with the support wheel shaft.

Referring to Fig. 9, support the axis hole that wheel shaft 6 penetrates support wheel 5, support wheel 5 can rotate around supporting wheel shaft 6.

Referring to Figure 10 and Figure 11, install when supporting wheel carrier 4, earlier supporting the axis hole that wheel shaft penetrates support wheel 5, the two ends of supporting wheel shaft are embedded two semiaxis holes supporting wheel carrier 4 from bottom to top, making support wheel be in two is close between the plate, make four locating pins 11 that support wheel carrier aim at four jiaos of the hole clippings of second slide rail 2 again, whole support wheel carrier 4 is pressed in the hole clipping from top to bottom, two cramps, 7 distortion of supporting wheel carrier 4 cross behind the middle rail 2 again that spreading buckles on two horizontal edges of hole clipping; When support wheel carrier 4 pressed downward to hole clipping, four spacers 13 on second slide rail 2 protruded upward from two locating slots that support wheel carrier respectively, and per two spacers 13 are positioned at the both sides of supporting axle stub fixedly positioning the support wheel shaft.

Because the lower surface of first slide rail also is subjected to the support of support wheel except the supporting that is subjected to ball retainer, so can keep exactly parallel when first slide rail and second slide rail relatively move, thereby when being hauled out, drawer, eliminated the bad gap between drawer panel and the drawer cupboard when drawer is closed along sliding straight.

Referring to Figure 12, embodiment 2 is a cover two joint guide rails, and it has only first slide rail 1 and second slide rail 2,, be equivalent to movable rail and retaining rail that tradition two saves guide rails.Second slide rail 2 is fixed in the drawer cupboard, and drawer is installed on first slide rail 1; Between first slide rail 1 and second slide rail 2 ball retainer is arranged.Front end at second slide rail 2 has one to support wheel carrier 4, supports on the wheel carrier 4 support wheel 5 is installed, and support wheel 5 is done to roll with the lower plane of first slide rail 1 and contacted.

Embodiment 1 and embodiment 2 are provided with a support wheel, and in other embodiment, support wheel can have two or more, correspondingly, support wheel carrier quantity and on second slide rail quantity of hole clipping all want corresponding increase; Also can be installed in a plurality of support wheels in the same support wheel carrier.

In addition, support wheel 5 and support wheel shaft 6 can be merged into a part, make the support wheel (profile such as Fig. 9) of one the two protruding axle of sideband, and protruding axle is slidingly matched with two semiaxis holes supporting on the wheel carrier.Can further reduce production costs like this.
