Abstract

The utility model discloses a can reduce frictional force's push-and-pull door structure, including the back timber, establish at the floorbar of back timber below and gliding push-and-pull door between back timber and floorbar, wherein, the lower surface of back timber is equipped with and supplies the gliding top spout of push-and-pull door embedding, the upper surface of floorbar is equipped with and supplies the gliding bottom spout of push-and-pull door embedding, be equipped with a plurality of rolling members in the spout of bottom, the rolling member supports the top with bottom spout and push-and-pull door lower surface mutually. By adopting the structure, the lower surface of the sliding door is abutted against the rolling part through the lower sliding block, when the sliding door slides, the rolling part converts the plane friction between the sliding door and the sliding groove into the rolling friction between the lower sliding block and the rolling part, and the friction force is greatly reduced. Compared with the prior art, this novel simple structure to can reduce push-and-pull door bottom friction, make the push-and-pull door slide more smoothly, in time push-and-pull door and spout take place to corrode simultaneously and also keep gliding smoothness nature, improve the practical life of push-and-pull door.

Description

Sliding door structure capable of reducing friction force

Technical Field

The utility model relates to a push-and-pull door structure field, concretely relates to can reduce frictional force's push-and-pull door structure.

Background

Sliding doors and windows are widely used as a common door and window structure. The sliding door and window structure has the advantages of no occupation of extra space, simple structure and the like. When the sliding door and window is used, the door and window plate can freely slide on the door and window frame, after long-time sliding, the sliding door and the sliding chute of the sliding door are easily corroded or abraded in a matching mode, so that the friction force between the sliding door and the sliding chute is increased, and the sliding door is blocked and stuck when sliding.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.

Disclosure of Invention

The utility model discloses a main aim at provides a can reduce sliding door structure of frictional force, can reduce sliding door bottom friction, makes the sliding door slide more smoothly.

In order to achieve the above purpose, the solution of the present invention is:

the utility model provides a can reduce sliding door structure of frictional force, includes the back timber, establishes the floorbar of back timber below and gliding push-and-pull door between back timber and floorbar, wherein, the lower surface of back timber is equipped with and supplies the gliding top spout of push-and-pull door embedding, the upper surface of floorbar is equipped with and supplies the gliding bottom spout of push-and-pull door embedding, be equipped with a plurality of rolling members in the spout of bottom, the rolling member supports the top with bottom spout and push-and-pull door lower surface mutually.

Furthermore, a limiting rod arranged along the extending direction of the bottom sliding groove is arranged above the bottom sliding groove, a limiting groove is formed between the limiting rod and the side groove wall of the bottom sliding groove, and the rolling piece rolls in the limiting groove.

Further, the rolling members are balls.

After adopting above-mentioned structure, the lower surface of push-and-pull door is equipped with the lower slider of embedding spacing inslot, the lower surface and the rolling member of lower slider support, and when the push-and-pull door slided, the rolling member converted the plane friction between push-and-pull door and the spout into the rolling friction between lower slider and the rolling member, had reduced frictional force greatly. Compared with the prior art, the novel sliding door has the advantages that the novel sliding door is simple in structure, friction at the bottom of the sliding door can be reduced, the sliding of the sliding door is smooth, meanwhile, the sliding door and the sliding groove are corroded in time, sliding smoothness is kept, and the service life of the sliding door is prolonged.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-2, a can reduce sliding door structure of frictional force, includes back timber 1, establishes floorbar 2 below the back timber 1 and at the gliding push-and-pull door of back timber 1 floorbar 2 between, wherein, the lower surface of back timber 1 is equipped with and supplies the gliding top spout 11 of push-and-pull door embedding, the upper surface of floorbar 2 is equipped with and supplies the gliding bottom spout 21 of push-and-pull door embedding, be equipped with a plurality of rolling members 3 in the spout 21 of bottom, rolling members 3 support against with bottom spout 21 and push-and-pull door lower surface mutually. After adopting above-mentioned structure, the top of push-and-pull door is led through the top spout, and the below is led through bottom spout, has strengthened the gliding stability of push-and-pull door, and the lower of push-and-pull door and rolling member rolling friction have reduced frictional resistance simultaneously.

Preferably, a limiting rod 211 arranged along the extending direction of the bottom sliding groove 21 is arranged above the bottom sliding groove 21, a limiting groove 212 is formed between the limiting rod 211 and the side groove wall of the bottom sliding groove 21, and the rolling member 3 rolls in the limiting groove 212. By adopting the structure, the rolling member 3 is prevented from rolling randomly, and the rolling member 3 is prevented from rolling out of the sliding groove and losing.

Preferably, the rolling parts 3 are balls, so that the structure is simple, and the production and the manufacture are convenient.

After adopting above-mentioned structure, the lower surface of push-and-pull door is equipped with the lower slider 4 of embedding spacing inslot 212, the lower surface and the rolling member 3 of lower slider support, and when the push-and-pull door slided, rolling member 3 changed the plane friction between push-and-pull door and the spout into the rolling friction between lower slider 4 and the rolling member 3, had reduced frictional force greatly. Compared with the prior art, the novel sliding door has the advantages that the novel sliding door is simple in structure, friction at the bottom of the sliding door can be reduced, the sliding of the sliding door is smooth, meanwhile, the sliding door and the sliding groove are corroded in time, sliding smoothness is kept, and the service life of the sliding door is prolonged.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
