Abstract

The name of the utility model is pulley wheel for door and window of rotating axle sliding type. The utility model belongs to architectural hardware commodity and is a rolling accessory in match use with the door and window of pushing and pulling type. The present pulley wheel for door and window all adopt the automatic rotating operating type of moving tilt wheel circling fixing wheel axle and the rolling structural form that the middle section of the wheel axle is sheathed with the tilt wheel and the both ends of the wheel axle are fixed on the side wall of the support bracket and the necessity of failure occurrence and service life reducing and the objectivity of uneasy manufacture and quality controlling difficult exist on the present pulley wheel for door and window. The utility model adopts the operation mode that the fixing tilt wheel is in joint rotating with the moving wheel axle and the structural form that the both ends of the tilt wheel with an axle are sheathed on an axle base to form a rolling mechanism component equipped in a support bracket to rotate and thus the utility model enables the both ends of the wheel axle and the upper portion of the hole of the axle base in mutual grinding and always in appropriate breaking-in state. The negative affect on rolling effect and service life of the pulley wheel caused by mutual grinding gap is eliminated and the quality controlling and quality optimizing of the pulley wheel from manufacturing to applying are guaranteed.

Description

Rotating shaft slidingtype door and window trolley

Technical field

The utility model belongs to the architectural hardware series products, is a kind of rolling annex that is used in push-pull door and window.

Background technology

Modern various push-pull door and windows, its bottom all is equipped with the rolling annex pulley of being convenient to move around.Facts have proved that the quality of pulley quality has crucial effects for the result of use of push-pull door and window.General door and window trolley is gone up nothing more than three types of ball bearing formula, needle roller tumbling-type, runner slidingtypes etc. by society now.These pulleys all adopt the drive manner that rotates voluntarily around fixing arbor wheel with the roller of activity, the form of structure that is fixed in support with wheel shaft stage casing cover roller, two ends and can rolls, fretting wear face during these pulley rollings has comprised roller endoporus and wheel shaft stage casing, make any imbalance of attrition part fit clearance, the little big or irregular pulley that all can make produces functional fault, as noise, jump, stall, stuck etc., even the normal pulley of initial mass, through constantly using, the fit clearance of attrition part also can increase gradually.Thereby determined to have now the certainty that various pulley exists the damage that breaks down to have the allotted portion of life reduced by having or getting more than one deserves and order, exist and make the objectivity difficult and control of quality difficulty.

Summary of the invention

1, adopted with the wheel shaft of activity and follow the co-rotational drive manner of fixing roller, tape spool roller two ends cover axle bed forms that the tourelle parts are allocated support into and the form of structure that can roll.

2, pulley bracket is faced shape and fallen trapezoidally to make into to upper, middle and lower three span access location length differently from existing second order, three rank of sublevel place arc-shaped transition are trapezoidal.

The advantage of above utility model is: 1, because the wheel shaft two ends radially head on axle bed, axle bed heads on door and window with the support disjunctor again and roll, so the wearing and tearing on top, axle bed hole certainly will make door and window produce and the down displacement of degree of wear equivalent, cause the move down normal healing of the attrition wearing and tearing vacancy of wheel shaft and axle bed along with door and window, wheel shaft and axle bed attrition place are in appropriate break-in state all the time.Have no way of producing such as the existing common various faults of various pulley.So just eradicated the attrition gap for the rolling effect of pulley and the negative consequence in application life, ensured that pulley is from manufacturing to quality control and the quality optimization of using reality.2, because the advantages of simple of structure makes that the making of pulley is especially convenient, cost significantly reduces.The needle roller tumbling-type pulley the most general with present application is example, its part before assembling has 6 kinds totally 13 (wherein 7 of needle rollers, 2 of seal covers), assembly process 5 roads, and the situation that repeats to allocate part owing to the non-absolute unification of the machining accuracy of each part influence production efficiency.The preceding part of the utility model assembling is 3 kinds totally 4 (2 of its central axis seats) only, assembly process 3 roads, and simple and convenient, there is not difficulty, both can save material, can improve work efficiency again, two-way reducing expenditure can reduce cost more than 10% approximately.

3, shorten at the following position of pulley bracket, and its two has vertical breach of one's own, has not only saved raw material, and just with the pulley with same rack making different application height, sublevel place arc-shaped transition then can be improved aesthetic feeling.

The vertical breach in position under 1 wheel shaft, 2 rollers, 3 tape spool rollers, 4 axle beds, 5 supports, 6 tourelle parts, 7 tourelle parts seats, 8 fixed screw holes, 9 supports among the figure.

The specific embodiment

As shown in the figure, wheel shaft 1 and the roller 2 tape spool roller 3 of body that unites two into one.Roller 2 can not radially slide, can not axial float, and the manufacturing materials of roller 2 must be the engineering plastics with certain physical and mechanical property.The manufacturing materials of wheel shaft 1 must be the metal with excellent corrosion resisting performance.

Fig. 3 is the axle bed 4 with alternative lasso and location double action, and the shape of axle bed 4, size, thickness, aperture and Kong Weijun can set among a small circle according to actual needs.The manufacturing materials of axle bed 4 also should be to have good abrasion performance, the metal of decay resistance, but its abrasion resistance must slightly be worse than the manufacturing materials of wheel shaft 1, with the axle bed 4 of the wearing and tearing interarea that guarantees both attritions and not at wheel shaft 1.

Fig. 6 is that the naked axle in the two ends of tape spool roller 3 is mixed the tourelle parts 6 that axle bed 4 is formed.

Shown in Figure 7 is the moulding pulley that support 5 has been equipped with tourelle parts 6.It is trapezoidal that the facing of support 5 is shaped as three rank, and top shows long because of fixed screw holes 8 is arranged, and the middle part is set according to roller 2 external diameters and reduced, and the bottom is only the shortest for booster action, junction, three rank arc-shaped transition; Two side, support stage casing is load-bearing principal part position, so especially abundant, the centre has tourelle parts seat 7, and this tourelle parts seat 7 can be located at the inboard or the outside of two side according to actual needs and in addition; Following position has vertical breach 9 of one's own because of short two.The manufacturing materials of support 5 should be the engineering plastics with certain physical and mechanical property, or kirsite.The planform of support 5 shown in Figure 7, the push-pull door and window of being suitable for plastic-steel, moulding wood, section bars such as glass fiber reinforced plastic, stainless steel being made is used.The door and window trolley supporting structure shape of aluminium alloy extrusions can be according to drive manner of the present utility model and form of structure otherwise designed.

Claims

1. rotating shaft slidingtype door and window trolley, it is characterized in that, follow the co-rotational drive manner of fixing roller with the wheel shaft of activity, form that the tourelle parts are allocated support into and the form of structure that can roll with tape spool roller two ends covers axle bed, and face that to be shaped as upper, middle and lower three span access location length different, trapezoid support falls on three rank of sublevel place arc-shaped transition.
