The tension spring tension adjusting device comprises a rack, a gear and a bearer; the bearer is installed behind the support; the bearer is provided with a rack guide groove at the bottom; two side wall plates of the bears are provided with a first shaft hole and a second shaft hole respectively; the bearer is provided with a ratchet on the top; the rack is provided with a traction groove at the front end and is inserted in the rack guide groove in the bearer; center of one side of the gear is provided with a shaft extension; the other side of the gear is provided with a protruding ring and an adjusting groove; the shaft extension is inserted in the first shaft hole in the bearer; the protruding ring is embedded in the second shaft hole in the bearer; the surface of the gear is contacted with the rack and the ratchet of the bearer simultaneously, and each tension spring has one end embedded in the traction groove in the rack and the other end connected with the slider. The utility model has a simple structure, is convenient and easy for installation and adjustment and can be installed on various drawer guide rails.
Description
Technical field
The utility model belongs to five metals, especially a kind of buffering returning device that is installed on the guide rail.
Background technology
The drawer that guide rail has been installed drags very suitable cunning, produce bump when closing and send sound for fear of drawer, most of guide rails all are provided with the buffering return mechanism, and spring that the after-stage dependence of closing at drawer is stretched in advance and buffer acting in conjunction drag drawer and slowly move up to complete closure.Because each parts particularly processing dimension and the material of spring there are differences, cause product assembling back disunity on indexs such as screen resilience, return speed in batch, influenced the quality of product, need improve.
Summary of the invention
The purpose of this utility model provides a kind of buffering guide rail and closes the power governor motion, and its spring tension can be regulated, and makes drawer guideway of the present utility model or other guide rail performance unanimities have been installed.
The utility model comprises support, damping tube, slip rail, slide block and extension spring, it is characterized in that it also has the extension spring tension-adjusting gear, and the extension spring tension-adjusting gear comprises tooth bar, gear and bearing; Bearing is installed in the support rear, and rest base has the tooth bar guide groove, and first axis hole and second axis hole are arranged respectively on the bearing two side wall panels, and ratchet is arranged at the bearing top; The tooth bar front end has traction grooved, and tooth bar inserts the tooth bar guide groove of bearing; There is shaft extension at gear one side center, and the gear opposite side has bulge loop and regulating tank, and shaft extension is inserted first axis hole of bearing, and bulge loop embeds second axis hole of bearing, and gear surface contacts with ratchet simultaneously with the tooth bar of bearing; A traction grooved that embeds on the tooth bar of extension spring, the other end of extension spring is connected with slide block.
The utility model has only increased a foolproof spring tension adjusting device of structure compared with traditional product, and its installation and adjust all very convenient easily; Obtained the meticulous adjusting of the power of closing by it, improved uniformity greatly with the batch products quality.The utility model is suitable to be installed on the various guide rails.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment extension spring tension-adjusting gear;
Fig. 2 is the exploded view of extension spring tension-adjusting gear;
Fig. 3 is that the A of Fig. 1 is to view;

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 4, the extension spring tension-adjusting gear is made up of bearing 5, tooth bar 7 and 8 three parts of gear.
Referring to Fig. 5, traditional buffering guide rail has support 1, damping tube 2, slip rail 3, slide block 4 and extension spring 6; Damping tube 2 is fixed on the support 1, and support 1 and slip rail 3 are installed on the retaining rail 21 of drawer guideway, and slide block 4 is sleeved on the slip rail 3, and slide block 4 is connected with damping tube 2; In the conventional guide rails buffer, have and also the having an of extension spring is set two extension springs are set, be provided with on the conventional guide rails buffer of two extension springs, article two, extension spring 6 two draw-in groove 9 that embed respectively on the slide block 4, article two, the other end of extension spring 6 embeds two traction grooved (not shown) that are produced on support 1 afterbody respectively, and the initial length of two extension springs is definite values.
In embodiment of the present utility model, article two, extension spring 6 two draw-in groove 9 that embed respectively on the slide block 4, article two, the other end of extension spring 6 initial length that embeds 14, two extension springs 6 of two traction grooveds on the tooth bar 7 respectively changes according to the degree of depth that tooth bar 7 inserts bearings 5.
During the product assembling, support 1 and bearing 5 all are to utilize card base of self and locating convex block to be fixed on above the retaining rail 21, with screwdriver turn gear, cooperate dynamometer to regulate the tension force that just can configure guide rail product rapidly.
As another kind of embodiment, support 1 and bearing 5 also can synthesize a part, promptly extend back at the afterbody of support 1 and make bearing 5, and there is not the difference on the function in both.
