Description
Technical field
The utility model relates to furniture hardware fitting, specifically a kind of structure-improved of three-section synchronous drawer guide rail.
Background technology
Common drawer guideway divides rail, middle rail, lower rail or active rail, mid-rail, retaining rail three joints, between active rail and mid-rail, mid-rail and retaining rail, there are roller or ball, roller and ball are retrained by retainer, while movement due to drawer, between guide rail, be rolling friction, so more laborsaving.In the use of three joint guide rails, it is found that because precision and the assembling means of part there are differences, cause the force of rolling friction between rail and rail inhomogeneous, between slide rail, the order of folding is uncertain, cause the drawer left and right sides to drag resistance inconsistent, affect feel.Meanwhile, due to the guide rail movement track imbalance of both sides, be easy to cause push mutually and prize between two rails, rocking a little less than causing guide rail bearing capacity and in use procedure, is therefore necessary it to do further to improve.
Utility model content
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of simple in structure, easy to assembly, operate steadily smoothly, and the structure-improved of robust a kind of three-section synchronous drawer guide rail.
The utility model object realizes with the following methods: a kind of structure-improved of three-section synchronous drawer guide rail, it comprises the quiet slide rail that stacks gradually installation, mid-rail and moving slide rail, between adjacent two rails, carriage is installed, between quiet slide rail and mid-rail, reset buffer means is installed, it is characterized in that: in described mid-rail, be provided with friction pulley free to rotate, friction pulley excircle contacts with moving slide rail and quiet slide rail, described moving slide rail is provided with tread plate with the movement locus of corresponding friction pulley on quiet slide rail, described tread plate is the tooth bar of processing in sliding track body.
Described tread plate is stamped to form for moving slide rail and quiet slide rail metal body material.
Described tread plate is separately positioned on the moving lower hem of slide rail and the bottom land of quiet slide rail.
Described friction pulley is fixedly mounted on the sidewall of mid-rail by rivet.
Described friction pulley is that flexible rubber and plastic cement material are made.
Described friction pulley surface is provided with anti-slip veins.
The beneficial effects of the utility model are: 1) simple in structure, easy to assembly, production cost is low, improve the market competitiveness.2) friction pulley being arranged in mid-rail can be when moving slide rail outwards moves, the synchronous mid-rail that promotes is outwards moved, limit sequence of motion and the distance of moving slide rail and mid-rail, avoid occurring, because of slide rail movement velocity and the chaotic drawer guideway unbalance stress causing of order, affecting its service life and bearing capacity.4) when the bearing capacity that is arranged on effective increase drawer of friction pulley, alleviate guide rail double swerve, extend guide rail service life.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.A kind of structure-improved of three-section synchronous drawer guide rail, it comprises the quiet slide rail 1 that stacks gradually installation, mid-rail 2 and moving slide rail 3, between adjacent two rails, carriage 4 is installed, between quiet slide rail 1 and mid-rail 2, reset buffer means 5 is installed, it is characterized in that: in described mid-rail 2, be provided with friction pulley free to rotate 6, friction pulley 6 excircles contact with moving slide rail 3 and quiet slide rail 1, described moving slide rail 3 is provided with tread plate 7 with the movement locus of corresponding friction pulley 6 on quiet slide rail 1, and described tread plate 7 is the tooth bar of processing in sliding track body.
Described tread plate 7 is stamped to form for moving slide rail 3 and quiet slide rail 1 metal body material, except adopting Sheet Metal Forming Technology, also can adopt annular knurl, and the techniques such as polishing, only need to go out coarse surface in sliding track body Surface Machining.
Described tread plate 7 is separately positioned on the moving lower hem 31 of slide rail 3 and the bottom land 11 of quiet slide rail 1.
Described friction pulley 6 is fixedly mounted on by rivet 61 on the sidewall of mid-rail 2, except employing rivet is fixing, also can adopt screw, and the modes such as screw or rotating shaft are fixed.
Described friction pulley 6 is made for flexible rubber material, and flexible material can produce certain deflection, forces friction pulley and tread plate to be combined closely, and ensures frictional force and synchronous effect between the two.
Described friction pulley 6 surfaces are provided with anti-slip veins, the design of anti-slop serrations can with security bar in groove intermeshing, increase contact area between the two, strengthen the frictional force between friction pulley and moving slide rail and quiet slide rail.
Operation principle: the friction pulley outer rim assembling closely contacts with the tread plate on moving slide rail and quiet slide rail, in the time of this guide rail and drawer assembling use, if user pulls out drawer body, first stressed moving slide rail outwards moves, due to friction pulley and moving slide rail close contact, so when moving slide rail outwards moves, will certainly drive friction pulley to rotate; Simultaneously friction pulley also with quiet slide rail close contact, so friction pulley produces thrust and promotes quiet slide rail in rotating, but quiet slide rail maintains static, the reaction force of its generation promotes the relatively quiet slide rail motion of mid-rail, thereby has realized the relative motion of moving slide rail and mid-rail.
Therefore no matter drawer guideway is in closing or opening, can realize being synchronized with the movement of moving slide rail and mid-rail, guarantee sequence of motion, speed and distance between the two, make the resistance of motion of two rails consistent, in the resistance of motion in the time ensureing drawer push-and-pull, also ensure the bearing capacity of drawer guideway, extended its service life.
Meanwhile, the installation of friction pulley can be played certain supporting role, strengthens the bearing capacity of guide rail.Simultaneously it can also play the spacing and supporting role in left and right, avoids drawer rocking from side to side of guide rail in use.In addition, friction pulley adopts flexible rubber material to make, and it can, when larger frictional force is provided, also have sound deadening, operational vibration and the large drawback of noise of avoiding conventional gears rack synchronous device to bring.Meanwhile, adopt the directly structure of punching press tread plate in guide rail body in this case, processing technology is simple, the complex structure of avoiding traditional structure to need additional tooth bar to bring, and assembling trouble and the high drawback of production cost, be therefore applicable to extensively promoting the use of.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; as the material of friction pulley, the structure of tread plate etc., these changes and improvements all fall within the scope of claimed the utility model.
