Abstract
The utility model discloses a manual lifting device of a rack of refrigerator, which belongs to the technical field of household appliances. The utility model provides an improved manual lifting device of the refrigerator rack, which solves the disadvantages that the direction of rotation of a dragline is multi, the using of a fixed pulley is multi, the mechanical efficiency is low, the front edge of the rack is exposed a little through manually regulating the edge of the fixed pulley, and the regulation is not convenient and the like. The utility model comprises a fixed pulley and a sling, wherein the fixed pulley is arranged on the periphery of the top portion of the inner wall of the refrigerator, and the sling which crosses through the fixed pulley is connected with the edge of the rack, the utility model is characterized in that the other end of the sling is fixedly connected with a scroll which is arranged in the middle of the top portion of the inner wall of the refrigerator, and a manual regulating wheel is arranged on the end portion of the scroll. The utility model has the advantages of simple structure, flexible operation, and simple and reliable control. More than two lifting devices are convenient to overlap, and the utility model is capable of being used in a freezer of refrigerator.
Description
Technical field
The utility model discloses a kind of manual hoisting device of refrigerator rack.Belong to household electrical appliance technical field.
Background technology
Before the utility model is made, can adapt to the article storage of different sizes in the certain limit lifting in order to make the rack in the refrigerator.The Chinese patent application number 01112021.5 disclosed refrigerator that refrigerator shelf is moved up and down, structure is the complicated mechanical transmission device, regulates highly limited.China Patent No. 02270801.4 disclosed " refrigerator rack lowering or hoisting gear ", structure is comparatively simple, regulates and highly satisfies instructions for use, it is many that deficiency is that stay cord turns to, and fixed pulley uses many, and mechanical efficiency is low, the manual adjustment wheel edge expose the rack forward position a little, regulate inconvenience.
Summary of the invention
The utility model is at the deficiency of 02270801.4 disclosed " refrigerator rack lowering or hoisting gear ", a kind of improved refrigerator rack lowering or hoisting gear is provided, solving stay cord turns to many, fixed pulley uses many, mechanical efficiency is low, the manual adjustment wheel edge expose the rack forward position a little, regulate disadvantages such as inconvenience.
Technical characterictic of the present utility model is: 1, will install by being installed in the rack bottom, and change into and be placed in refrigerator inwall top; 2, spool replaces rolling wheel, and the solution stay cord turns to many, and fixed pulley uses many, the deficiency that mechanical efficiency is low; 3, the regulating wheel of Bao Luing makes that adjusting is more convenient.
Below introduce structure of the present utility model in detail, a kind of refrigerator rack manual hoisting device, by being installed in refrigerator inwall top fixed pulley all around, the hoist cable that passes fixed pulley connection rack edge constitutes, the other end that it is characterized in that hoist cable is fixedlyed connected with the spool of refrigerator inwall crown center, and there is manual adjustment wheel the end of spool.
There is the spool self-locking positioning mechanism end of spool and manual adjustment wheel junction.
Folding rocking handle is arranged on the manual adjustment wheel, can accelerate governing speed.
The structural principle of spool self-locking positioning mechanism is identical with " locking function " structural principle of disclosure in the China Patent No. 02270801.4 disclosed " refrigerator rack lowering or hoisting gear ".Its principle of compositionality is traditional fogey phone dial transmission principle, no longer describes in detail.
The spool self-locking positioning mechanism specifically comprises fixing mandrel, be enclosed within mandrel and mandrel and be the spool that is slidingly matched, mandrel one end is fixed on the tank wall by axle bed, the other end of mandrel is with one section locking spring, locking spring and mandrel are combines closely, the outstanding spring of locking spring head and the tail bending surface constitutes stop pin, stop pin places between two semi-annular shape boss of the manual adjustment wheel that is enclosed within on the mandrel and spool engagement, spool is fixed on the tank wall by bearing block, and manual adjustment wheel connects end at mandrel by capping, screw.
During the utility model work, shake the manual adjustment wheel of roller tube end, spool drive hoist cable rises rack or falls; When stopping to shake, self-locking mechanism is with spool and fixing mandrel locking, and rack stops on the corresponding position.Because manual adjustment wheel is with the locking spring relaxation all the time when rotating, spool is with the locking spring compression all the time when rotating, so produced positioning function at random.
The utility model has the advantages that simple in structurely, manoeuvrable is controlled easy to be reliable.Be convenient to plural lowering or hoisting gear stack and be provided with, can be used in the refrigerating box of refrigerator.
