Abstract

The utility model relates to the technical field of sliding rails, in particular to a double-linkage sliding rail, which comprises an upper rail, a middle rail and a bottom rail, wherein the middle rail is sleeved and connected on the side edge of the bottom rail in a sliding way, the upper rail is sleeved and connected on the outer side of the middle rail in a sliding way, the two end parts of the upper rail are inwards bent to form folding pieces, the bottom of each folding piece is provided with a first rack along the length direction, the double-linkage sliding rail realizes sliding through the mutual matching of the first rack arranged on the folding piece of the upper rail, a gear arranged in the middle part of the middle rail and a second rack arranged on the bottom rail, when the upper rail is pulled, the upper rail is forced to move, and simultaneously drives the middle rail to move because of the gear traction, thereby achieving the double-linkage effect, not only reducing the operation time of sliding and stretching, but also relieving the impact when the upper rail stretches out, and when the upper rail is pulled to the maximum, the upper rail is in an unsettled state, at the moment, the gear also has certain supporting capacity, reasonable in design and structure are ingenious.

Description

Double-linkage sliding rail

Technical Field

The utility model relates to a slide rail technical field especially relates to a double linkage slide rail.

Background

The sliding rails are also called as guide rails and sliding ways, and refer to hardware connecting parts which are fixed on a cabinet body of furniture and used for enabling a drawer or a cabinet plate of the furniture to come in and go out, a plurality of sliding rail structures are applicable to the connection of wood systems such as cabinets, furniture, document cabinets, bathroom cabinets and the like and drawers of the furniture such as steel drawers and the like, the sliding rails also have the sliding rail types such as hidden sliding rails, horse riding drawing sliding rails and the like, and in the sliding rails, the design of adopting a gear structure has great advantages, for example, the sliding rails can be very smooth and synchronous, and in addition, if the sliding rails are additionally configured, the sliding rails also have the functions of buffering closing or pressing and rebounding opening.

Present slide rail mostly is last rail and well rail and passes through the gear cooperation, and although this mode can smooth-going flexible, can't form the linkage effect between well rail and the end rail to the flexible volume of rail in the control of not being convenient for.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the linkage effect cannot be formed between the middle rail and the bottom rail in the prior art, and providing a double-linkage slide rail.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the double-linkage sliding rail comprises an upper rail, a middle rail and a bottom rail, wherein the middle rail is sleeved with and is connected to the side edge of the bottom rail in a sliding mode, the upper rail is sleeved with and is connected to the outer side of the middle rail in a sliding mode, folding pieces are bent inwards at two ends of the upper rail, first racks are arranged at the bottoms of the folding pieces along the length direction, second racks are arranged in the middle of the bottom rail and are arranged under the first racks, gears are connected to the side wall of the middle rail in a rotating mode, and the gears are arranged between the second racks and the first racks and are meshed with each other.

Preferably, sliding assemblies are installed at the top and the bottom of the middle rail, and a plurality of sliding wheels are arranged in the sliding assemblies.

Preferably, the top of the upper rail is rotatably connected with a roller.

The utility model provides a pair of linkage slide rail, beneficial effect lies in: the utility model discloses a first rack of installation on the upper rail folded piece, the mutually supporting of installation second rack realizes sliding on the gear at well rail middle part and the bottom rail, in the time of the pulling upper rail, can move because the gear pulls the drive well rail and remove when the upper rail atress removes, thereby reach double linkage effect, not only can reduce the flexible operating time of slip, and can alleviate the impact when the upper rail stretches out, when pulling open simultaneously and reaching the biggest, the upper rail is outside in unsettled state, the gear also has certain supporting capability this moment, reasonable in design and structure are ingenious.

Drawings

Fig. 1 is a schematic structural view of a double-linkage slide rail provided by the present invention;

fig. 2 is a schematic sectional view of a dual-linkage slide rail according to the present invention.

In the figure: 1. rail mounting; 2. a middle rail; 3. a bottom rail; 4. a roller; 5. folding a sheet; 6. a first rack; 7. a second rack; 8. a gear; 9. a sliding assembly; 10. a sliding wheel.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a double-linkage slide rail, including upper rail 1, middle rail 2 and bottom rail 3, middle rail 2 overlaps and establishes and sliding connection on the side of bottom rail 3, upper rail 1 overlaps and establishes and sliding connection in the outside of middle rail 2, the inside bending type in both ends of upper rail 1 has tabs 5, tabs 5's bottom is provided with first rack 6 along length direction, bottom rail 3's middle part is provided with second rack 7, second rack 7 sets up under first rack 6, rotate on middle rail 2's the lateral wall be connected with gear 8, gear 8 sets up between second rack 7 and first rack 6 and intermeshing.

The top and the bottom of well rail 2 all install slip subassembly 9, are provided with a plurality of movable pulleys 10 in the slip subassembly 9, and the slip subassembly 9 of setting avoids going up rail 1 and well rail 2 to take place to rock when sliding, and the movable pulley is arranged and is made to go up rail 1, well rail 2 and the bottom rail 3 between can freely make a round trip to slide in top surface and side, and the top of going up rail 1 is rotated and is connected with gyro wheel 4.

A working mode; the during operation, first rack 6 of installation on folded piece 5 of upper rail 1, install second rack 7 on installation gear 8 and bottom rail 3 at the middle part of middle rail 2, when the pulling upper rail 1, can drive middle rail 2 because gear 8 pulls when the upper rail 1 atress removes and remove, thereby reach double linkage effect, not only can reduce the flexible operating time of slip, and can alleviate and strike when upper rail 1 stretches out, simultaneously when pulling open and reach the biggest, upper rail 1 is outside in unsettled state, gear 8 also has certain supporting capacity this moment, reasonable in design and ingenious structure.
