Description

Adjusting pulley

Technical Field

The utility model relates to the field of hardware fittings, in particular to an adjusting pulley.

Background

The pulley is widely applied in life, people can often see the figure of the pulley, such as a clothes hanger, a flagpole, a crane, pulley casters and the like, the pulley can be divided into a fixed pulley and a movable pulley, the fixed pulley has the advantage that the direction of force can be changed, but the force can not be changed, namely, people can not feel the effect of saving labor by using the fixed pulley, and the movable pulley can change the force direction but can pull an object in a labor-saving way by using the movable pulley.

The pulley can also be used for a trolley or an aluminum alloy door window, so that people can conveniently push and pull, but the pulley is certainly abraded in the long-time sliding process to influence the sliding effect, so that the central height position of the pulley needs to be adjusted.

Disclosure of Invention

The utility model aims to solve the technical problem of providing an adjusting pulley, which can be adjusted by adjusting a bolt assembly, so that the adjustment of the pulley is simple and reliable.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an adjusting pulley, includes the base, the base be provided with the pulley bracket who uses the pivot as rotation center, pulley bracket be provided with rotatable pulley, pulley bracket be provided with adjustable bolt assembly.

As a further improvement of the utility model, the base comprises a horizontal bracket and a vertical bracket, wherein the horizontal bracket is connected with one end of the vertical bracket in a welding way, and the other end of the horizontal bracket is fixedly connected with the other end of the vertical bracket through a screw. The base is divided into two supports, so that the processing and forming are facilitated, and the assembly is convenient.

As a further improvement of the utility model, the bolt assembly comprises an adjusting bolt penetrating through the horizontal bracket and abutting against the pulley bracket, and a nut screwed with the adjusting bolt. The adjusting bolt is used for adjusting the movement of the pulley support, and can be locked through the arrangement of the nut, so that the pulley support is ensured to be in a stable state position and to run stably.

As a further improvement of the utility model, the pulley bracket is provided with a rotating shaft, the horizontal bracket is provided with a rotating hole, and the rotating shaft is rotatably connected with the rotating hole. Because the rotating relation exists between pivot and the commentaries on classics hole, so the pulley support can realize rotating around the pivot to reduce horizontal support's whole volume, reduce cost.

As a further improvement of the utility model, the top end of the horizontal bracket is provided with a set screw. The horizontal bracket can be connected and fixed with the cart frame or the aluminum alloy door and window frame through the set screw.

As a further improvement of the utility model, the pulley is made of nylon material. The style of pulley has many kinds, and the inside card of most pulleys all is equipped with antifriction bearing to reduce coefficient of friction, make the roll of pulley more smooth and easy, the style that adopts also is so in this embodiment, and the pulley adopts the nylon materials preparation simultaneously, because the nylon materials has good wearability, impact resistance, corrosion resistance, can prolong the life of pulley.

The pulley bracket has the advantages of simple structure and convenient and reliable adjustment, and the up-and-down movement of the pulley bracket can be realized through the adjustment of the bolt assembly, so that the up-and-down movement of the pulley is realized. The pulley bracket rotates by taking the rotating shaft as a rotating center, the whole volume of the pulley bracket can be effectively reduced, the cost is reduced, the central height position of the pulley can be adjusted through the adjustable bolt assembly, and the process structure is simple and reliable, is convenient to use and operate, and is suitable for batch production and popularization.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 2: the utility model provides an adjusting pulley, includes base 1, and base 1 is provided with and uses pivot 3 as rotation center's pulley bracket 2, and pulley bracket 2 is provided with rotatable pulley 4, and pulley bracket 2 is provided with adjustable bolt assembly 5.

The base 1 comprises a horizontal support 10 and a vertical support 11, wherein the horizontal support 10 is connected with one end of the vertical support 11 in a welding mode, and the other end of the horizontal support is fixedly connected with the other end of the vertical support through a screw 6.

The bolt assembly 5 includes an adjusting bolt 50 penetrating the horizontal bracket 10 and abutting the pulley bracket 2, and a nut 51 threadedly engaged with the adjusting bolt 50.

The pulley bracket 2 is provided with a rotating shaft 3, the horizontal bracket 10 is provided with a rotating hole 100, and the rotating shaft 3 is rotatably connected with the rotating hole 100.

The top end of the horizontal bracket 10 is provided with a set screw 101.

The pulley 4 is made of nylon material.

As shown in fig. 3, in fig. 3a, the adjusting bolt 50 moves to the right, and the pulley 4 moves upward when contacting the cart or the al-alloy door and window guide rail due to the rotational relationship between the pulley bracket 2 and the horizontal bracket 10; in fig. 3b, the adjusting bolt 50 moves to the left, the pulley 4 and the pulley bracket 2 are pushed out to the left by the adjusting bolt 50, the pulley 4 moves downwards, and the up-and-down movement of the pulley 4 is 3 mm in the embodiment, and the movement size is different according to the size.
