Abstract
The utility model discloses a kind of pulleys being provided with directive wheel in side wall, it is made of the holder, idler wheel and connecting shaft of n fonts, the wheel shaft of the idler wheel is horizontally mounted between two vertical portions of holder, the connecting shaft is vertically installed at the top of holder, it is connected separately with directive wheel on two vertical portions of the holder, the directive wheel and idler wheel are axially vertical, and wheel rim protrudes from the vertical portion outer wall of holder.The idler wheel and directive wheel of pulley are rolled in the bottom surface of grooved track, madial wall respectively, it is ensured that idler wheel not will produce shaking or shake, effectively improve the article stability when moving using the pulley, and reduce noise.
Description
Technical field
The utility model is related to pulley technical fields, and in particular to a kind of pulley being provided with directive wheel in side wall.
Background technology
Sliding friction between object is converted to rolling friction by pulley, effectively reduces resistance and abrasion that frictional force is brought,
There are many applications in daily life；According to application environment difference, form, the structure of pulley are varied,
In for grooved track structure be generally by n fonts holder, be connected to the idler wheel of holder and connecting shaft forms, to prevent from propping up
Sliding friction between frame and track madial wall, widespread practice are to reduce the width of holder, it is slightly less than track, make the two
Between there are gap, this results in pulley to there is the space moved left and right in track, had both been susceptible to pulley and has been pasted with track unilateral side
Sliding friction is closed, resistance and abrasion are increased, and to will produce shaking when moving using the article of the pulley, built on the sand and is made an uproar
Sound is big, such as：Glass sliding door.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pulleys being provided with directive wheel in side wall, can solve
There is the space moved left and right in existing pulley, cause not only to be easy sliding friction in the track of groove profile, but also be easy to make to use the cunning
The article of wheel generates shaking when moving, built on the sand and the big problem of noise.
The utility model is achieved through the following technical solutions：
A kind of pulley being provided with directive wheel in side wall is made of, the idler wheel the holder, idler wheel and connecting shaft of n fonts
Wheel shaft be horizontally mounted between two vertical portions of holder, the connecting shaft is vertically installed at the top of holder, the two of the holder
Directive wheel is connected separately on vertical portion, the directive wheel and idler wheel are axially vertical, and wheel rim protrudes from outside the vertical portion of holder
Wall；Directive wheel makes the bottom surface of pulley and grooved track, madial wall all be in rolling contact, and frictional force is small, both eliminates gap, prevents
Pulley is bonded sliding friction with track unilateral side, but can pulley by along track lateral force forward or backward will on
When shifting, which is offset by the stiction between directive wheel and track madial wall, anti-limited slip wheel is shaken above and below,
Ensure that pulley smoothly moves in grooved track, effectively improves the article stability when moving using the pulley, and drop
Low noise.
The further scheme of the utility model is that window, the guiding are respectively arranged on two vertical portions of the holder
The axis of wheel is vertically-mounted in the window, saves space, is conducive to the miniaturization of pulley.
The further scheme of the utility model is to be connected separately at least two guiding on two vertical portions of the holder
Wheel forms forward and backward at least two fulcrum, so that pulley is slided in track and more stablizes, and can be in pulley by along track
When lateral force forward or backward, applies different moment of frictions, be more effectively prevented from pulley and shake above and below.
The further scheme of the utility model is, on each vertical portion of the holder on two adjacent directive wheels,
Under be staggered and/or two vertical portions of the holder on two directive wheels of opposite position be staggered above and below；Staggeredly
The directive wheel of setting more saves space, is further conducive to pulley miniaturization.
The utility model compared with prior art the advantages of be：
The idler wheel and directive wheel of pulley are rolled in the bottom surface of grooved track, madial wall respectively, it is ensured that idler wheel not will produce rolling
Dynamic or shake effectively improves the article stability when moving using the pulley, and reduces noise.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
A kind of pulley being provided with directive wheel in side wall as shown in Figure 1, is flatly pacified by the holder 1 and wheel shaft of n fonts
Idler wheel 2 between two vertical portions of holder 1 forms, and the top middle portion of the holder 1 of the n fonts is equipped with vertical connection
Axis 6 is symmetrically arranged with window 5 on two vertical portions of the holder 1 of the top of the idler wheel 2, two has been mounted side by side in each window 5
Vertical axis 4, there are one directive wheel 3, the diameter of the directive wheel 3 is more than the vertical portion of holder 1 for rotation connection on every axis 4
Wall thickness makes its wheel rim protrude from the outer wall of holder 1；About 3 two directive wheels in each window 5 are staggered, and two
Two directive wheels 15 of opposite position are also staggered above and below in window 5.
In the present embodiment, for ease of assembly, axis 4 is mounted in a frame, is then embedded in window with frame
In mouth 5.
The pulley is connected with grooved track madial wall interference fit, and grooved track madial wall is made to generate centainly directive wheel 3
Pressure, the frictional force generated by the pressure is very little in the resistance of the mobile generation of rectilinear direction to directive wheel 3, but can
To effectively prevent directive wheel 3 to deviate rectilinear direction, so that it is guaranteed that pulley smoothly moves.
