Abstract

The utility model discloses an oil controlling type window and door pulley for an encircling trough plug. Because the crucial rolling friction part is limited by the structure in the prior traditional window and door pulley, the use amount of the lubricating grease is less, the default that the lubricating and protecting period can not long, and the function failure or the corrosion damage of the pulley is easy to happen in the short period exists. The utility model adopts a structural form that the cylindrical plug with the encircling trough with more than one circumference communicated at both ends is arranged inside the inner holes of a tubular-shaped wheel axle to ensure the cylindrical plug and the wheel axle to be closely combined together, the outer drainage of the lubricating oil storage in the wheel axle can be resisted and controlled, thus the longer protection of the rolling components of the pulley can be obtained, the longer maintenance of the anti-rotted and wear-resistant performance can be obtained, and the advantage is created for prolonging the normal service life of the pulley and optimizing the quality of the pulley.

Description

Circumferential groove stopper control oil formula door and window trolley

Technical field

The utility model belongs to the architectural hardware series products, is the rolling annex of adapted on the push-pull door and window.

Background technology

Existing traditional door and window trolley, because key rolling friction position is subjected to structural limitations, the lubricant grease consumption is on the low side, exists the lubrication protection phase permanent inadequately, easily makes pulley that the defective of functional fault or corrosion and damage took place in short-term.

Summary of the invention

The utility model purpose provides a kind of circumferential groove stopper control oil formula door and window trolley.

The technical solution of the utility model is: adopt to insert in the endoporus of tubular wheel shaft to have the logical structure that both is closely linked around the cylindrical plug of groove in above two of a week.

The utility model has the advantages that: can hinder in the control restraining wheel shaft and store up leaking of lubrication oil, make the rolling member of pulley thereby obtain more permanent protection, the corrosion-resisting wear-proof performance obtains more permanent keeping, and for prolonging the normal application life of pulley, optimizes the quality of pulley and has created advantage.

Among the figure: 1 reinforced axle sleeve is equipped with groove, 2 pincers profile shaft seats, 3 are put wheel chamber, 4 stake bodies, 5 axle sleeves, 6 stoppers, 7 wheel shafts, 8 rollers, 9 axle sleeve reinforced walls, 10 axle sleeve holes, 11 axle sleeve hole bottom surfaces, the 12 anti-fore-sets that stagnate, 13 stopper buttons edge, the outer diametric plane of 14 stoppers, 15 spiral grooves, 16 groove imports, the outlet of 17 grooves, 18 wheel axle end surfaces, 19 wheel shaft endoporus, the outer diametric plane of 20 wheel shafts.

The specific embodiment

With the desirable engineering plastics of performance, through injection moulding machine-shaping stake body 4, roller 8, stopper 6, with high-quality steel or steel pipe through machining moulding wheel shaft 7 and axle sleeve 5, wheel shaft 7 is pressed into roller 8 with suitable interference fit, make both unite two into one body such as Fig. 8, get stopper 6 and be pressed into an endoporus 19, make outer diametric plane 14 coaxial inner 19 diametric planes of stopper become interference to join pressure, make the stopper button be close to (in axle hole 19, injecting an amount of fluid lubrication oil in the process) mutually with axial end 18 along 13 from the wheel shaft two ends.Get axle sleeve 5 covers and be assigned in wheel shaft 7 two ends, the outer diametric plane 20 of wheel shaft is cooperated with 10 one-tenth appropriate gap of axle sleeve hole, make the anti-fore-set 12 that stagnates appropriate gap be arranged with axle sleeve hole bottom surface 11, become the rolling member that makes up together as Fig. 2 bottom bracket axle 5, stopper 6, wheel shaft 7, roller 8, be pressed in the stake body 4 with this parts contraposition, make wheel chamber 3, roller 8 implantation sites, the dual-side that makes axle sleeve reinforced wall 9 is along going into the equipped groove 1 of the reinforced axle sleeve in position, the outer diametric plane of axle sleeve hole 10 is gone into the pincerlike axle bed 2 in position, is the utility model finished product pulley.Because lubrication oil has viscosity and seepage flow, during pulley rolling, its groove outlet 17 of can not trickling, can not be trapped in wheel shaft endoporus 19 the insides forever yet, and fixed meeting is along groove import 16, groove 15 moves back when advancing when going through, not only disconnected but also continuous process, progressively, be interrupted, move micro-ly and let out outside the groove outlet 17, be applied to wheel shaft 20 with axle sleeve 10 place that rubs mutually, and when the pulley stall is static, no matter groove outlet 17 is in height which kind of position up and down, except that certainly will flowing out near the lubrication oil at its place, in all the other storage or can not release outside the groove outlet 17 at the oil of " on the way " (oil reserve account for can store up the space do not satisfy be prerequisite), so desirable the actual effect of controlling lubrication oil automatically.

Claims

1. a circumferential groove stopper control oil formula door and window trolley is characterized in that, adopts to insert in the endoporus of tubular wheel shaft to have the logical structure that both is closely linked around the cylindrical plug of groove in above two of a week.
