Abstract

The utility model relates to a universal pulley base which comprises a bottom board, a casing, a pendulum shaft, a pendulum bar, screws, a pulley base, a pulley shaft, a pulley, etc. The utility model is characterized in that the bottom board of is directly connected with the casing, the upper end of the pendulum bar is made into a cylinder, and the pulley base which is arranged on the cylinder can rotate for 360 DEG around the cylinder; a strip-shaped pendulum bar groove and a pendulum shaft groove which are vertical to each other are arranged on the inner top wall of the casing, and the groove edges of the two grooves have equal height; the pendulum bar and the pendulum shaft are correspondingly arranged in the two grooves, and the decussation of the pendulum bar and the pendulum shaft is on the same plane; the pendulum bar swings for 70 DEG to 110 DEG in the groove around the pendulum shaft, so that the steering angle is wide, and the intensity is high. Accordingly, a pulling rope runs under the optimum state.

Description

A kind of universal pulley base

Technical field

The utility model belongs to clothes hanger hanger corollary equipment, specifically is a kind of rope turn to, commutate pulley gear of usefulness.

Background technology

Existing cross-axle universal shaft pulley base, by base plate, housing, be positioned at the fork inside and outside the housing, the fork lower end is connected with base plate, balance staff vertically connects balance staff, and pulley is connected on the pulley base by pulley spindle, and pulley base is connected the fork upper end by screw, because pulley base is fixed with respect to fork, can not rotate,, cause trouble so equipment need be firmly believed direction when mounted.In addition, because the right-angled intersection of fork and balance staff is not at grade, for steering angle and the tensile strength that satisfies pulley base, needed to stretch to such an extent that need do greatlyyer than long or housing sphere be positioned at the outer fork upper end of housing, like this, except the approved product with the market does not match, also cause the pull rope knuckle big, job-hopping or interference operation easily, and during work, active force mainly is to be born by fork, and not on base plate, fork is easy to fracture, and shortens the service life of equipment.

Summary of the invention

The utility model purpose is that a kind of compact conformation, rationally will be provided, and easy to assembly, the intensity high cost is low, can with the supporting cross-axle universal shaft pulley base of approved product.

The purpose of this utility model can realize by following scheme: a kind of universal pulley base, include housing, be positioned at the base plate of housing, be assemblied in the balance staff in the housing, fork, be connected in the pulley base of fork upper end and be assemblied in pulley in this pulley base and pulley spindle etc. with screw, it is characterized in that, described base plate directly is connected with housing, a cylinder is made in the upper end of described fork, described pulley base dress thereon, and can be around this cylinder rotation, roof in the described housing is provided with a bar shaped fork groove, this groove and shell back down logical, the place is provided with a vertical with it balance staff groove in the middle of the fork groove, balance staff is positioned at this groove, and described fork lower end is assemblied in the fork groove by balance staff, and fork is swung in this groove around balance staff.

The pulley base of such scheme can rotate 360 ° around cylinder.

The fork of such scheme angle around balance staff swing in the fork groove is 70 °-110 °.

The base plate of such scheme is respectively to open an installing hole on the housing at balance staff groove two ends with being connected of housing, and base plate is connected with housing with screw by installing hole.

The fork groove of such scheme and the groove of balance staff groove are along contour, and the right-angled intersection of fork and balance staff is in same plane.

The utlity model has following advantage and effect:

1, rational in infrastructure, base plate is close to fork groove and balance staff groove, directly is connected with housing, and is stressed jointly with housing, has intensity height, the non-damageable advantage of fork.

2, compact conformation, because the right-angled intersection of balance staff and fork lower end is in a plane, satisfy 90 ° of pivot angles, housing outside lever length is lacked half than the housing outside lever length of background technology, active length is reasonable, make pull rope be in optimal operational condition, do not job-hop, do not have and interfere operation, service life of equipment is long.

3, steering angle is wide, satisfies varying environment and installs.

Description of drawings

Fig. 1 is a kind of concrete mode broken section structural representation of the utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the structural representation of the interior fork groove of housing and a kind of concrete mode of balance staff groove.

Fig. 4 is the structural representation of a kind of concrete mode of fork.

From Fig. 1--4 can see, universal pulley base of the present utility model, comprise base plate 1, housing 2, balance staff 3, fork 4, screw 5, pulley base 6, pulley spindle 7 and pulley 8 etc., feature is to be provided with bar shaped fork groove 10 and the bar shaped balance staff groove 9 that is mutually quadrature at the housing inner roof wall, two groove grooves are along contour, fork groove 4 is opened the shell top, balance staff 3 and the fork 4 that inserts from housing 2 tops are installed in respectively the corresponding groove, both right-angled intersections are in same plane, fork 4 is around balance staff 3 swings, best pivot angle is 90 °, cylinder is made in housing 2 outside levers 4 upper ends, length is reasonable, and pulley base 6 is loaded on fork 4 upper end cylinders, and rotates around it 360 °, can select like this to installation, as long as after loading onto, the rotary pulley seat makes pulley get final product towards the pulley on the drying rack tool, satisfying varying environment installs, assembling is not only convenient but also simple, and in addition, base plate 1 is close to fork groove 4 and balance staff groove 3, and be connected with housing 2 with screw 11, this structure, during work, active force is mainly born jointly by base plate 1 and housing 2, and fork 4 is stressed little, not fragile, intensity height, long service life.

Claims
