Abstract

The utility model relates to a cabinet door hoisting pulley wheel, which is particularly suitable for being installed and used on a push-and-pull mobile cabinet door, a push-and-pull mobile door and a push-and-pull mobile window. The utility model is composed of a shaft and a fixing column which are connected into a whole, wherein, both ends of the shaft are connected with wheels; the fixing column is arranged on a movable plate. The utility model also comprises a fixing plate, wherein, the movable plate of a belt wheel is fixed on the fixing plate, namely, the hoisting pulley wheel is composed of the movable plate and the fixing plate; the movable plate is fixed on the fixing plate, in the way, part of the load bearing force bore by the wheels on the movable plate is transferred onto the fixing plate so that the force bore by the wheels is greatly reduced, and thereby, the utility model is not easy to damage, and the service life is prolonged. When the cabinet door is pushed or pulled to move by hands, the hand feeling is light, and therefore, the cabinet door is ensured to be move lightly and flexibly; simultaneously, the heights of the wheels on the movable plate can be adjusted by screw threads to meet the installing requirements of cabinet doors of different heights, and the range of use is enlarged.

Description

Cupboard gantry crane dress pulley

Technical field

The utility model relates to the hardware accessory that uses on a kind of furniture, suits especially at the cupboard door of pull-push moving type, the cupboard gantry crane dress pulley of installing and using on door, the window.

Background technology

The patent No. 98225173.4 " door and window hanging wheel " and commercially available cupboard door lifting pulley, just determined stress point all to concentrate on the hanging wheel of moving movement by its structure, hanging wheel is under the stress for a long time, can influence its application life, heavy, the effort of the feel of the moving door of push-and-pull simultaneously, especially promote the bigger moving door of surface area, its feel is heavy just more obvious.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of follow-on cupboard gantry crane dress pulley is provided, is installed on the cupboard door, feel is light, laborsaving during the pull-push moving type door, and long service life, and is not fragile.

The utility model solves the problems of the technologies described above the technical scheme that adopted and is connected with the axle of wheel by: cupboard gantry crane dress pulley by two ends and links into an integrated entity with fixed leg on the portable plate and formed, and also includes fixed head, and the portable plate of described belt wheel is fixed on the fixed head.

Compared with prior art, advantage of the present utility model is: original lifting pulley is the portable plate by belt wheel, be fixed on the both sides, cupboard door upper end and use, suffered power all concentrated on severally on the wheel when weight of whole cupboard door and cupboard door were mobile, and stress is concentrated, used for a long time fragile and influences its application life.Now lifting pulley is made up of portable plate and fixed head two parts of belt wheel, and fixed head is fixed on the cupboard door, and portable plate is fixed on the fixed head again, can make like this and take turns a bearing capacity part of being born on the portable plate and transfer on the fixed head, it is a lot of that the suffered bearing capacity of wheel is reduced, thereby not fragile, prolonged its application life, pull the cupboard door simultaneously when mobile, feel is light, and it is brisk, flexible to have guaranteed that the cupboard door moves.

Two-wheeled is by being threaded on screw on the axle and the fixed leg, and because of the height of cupboard door has difference, the length of screw thread on the available adjustment fixed leg is come the height of regulating wheel, satisfies the installation needs of differing heights cupboard door, has enlarged the scope of application.

The specific embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing:

Fixed head 6, on have logical, screw cross section to be The flat board of shape, respectively there is a breach 8 the upper and lower two edges of intermediate groove.

Portable plate 5, on have the through hole cross section to be

The flat board of shape has a latch hook 7 that is 90 ° of bendings in the middle of the lower limb.

Axle 3 is for the intermediate cross-section Shape, and the multidiameter of a screw is arranged.

Through hole rivet clasp on wheel 1, the pad 2 is passed on two-wheeled 1 in axle 3 two ends, portable plate 5 upper surface through hole rivet clasp one ends are the fixed leg 4 of screw thread, axle 3 usefulness are threaded on screw and the fixed leg 4 on it and are integral, constitute one group of pulley on the portable plate 5, as required, also can be on portable plate 5 secured in parallel two fixed legs 4, two groups of pulleys are installed respectively.

The portable plate 5 that pulley is installed is screwed in the groove in the middle of the fixed head 6, and make external surface height unanimity, in same plane, concordant mutually, as shown in Figure 2.And make latch hook 7 on it be close to breach 8 places of fixed head 6 lower ends, and external surface is concordant, as shown in Figure 1, cupboard gantry crane dress pulley is assembled into.

During use, earlier two fixed heads 6 are screwed, and then portable plate 5 are fixed in the groove of fixed head 6, and the wheel 1 of portable plate 5 upper ends is cooperated with slide rail 9 on being fixed on doorframe with screw in cupboard both sides, face upper end behind the door.As long as the cupboard door is moved in push-and-pull gently, wheel 1 just can easily slide in slide rail 9, and the cupboard door will open or close.
