Abstract
The utility model discloses a refrigerator rack elevating gear, including rack and refrigerator heat preservation, its characterized in that: the four corners that four piston cylinders are located the rack is respectively installed to the bottom of refrigerator heat preservation, be provided with the piston in the piston cylinder, piston cylinder top and hinge joint are passed to a piston rod one end, and the other end is connected with the rack, and both ends are connected with the water pipe respectively the piston cylinder inner wall about, the water pipe is connected with the water tank of water pump respectively, installs positive and negative switch bottom the refrigerator heat preservation, positive and negative switch passes through the electric wire and links to each other with power and water pump respectively, through the improvement to current structure, use piston cylinder and piston rod to adjust the height of rack as required, provide sufficient space for placing big article, and easy operation, control is convenient nimble, this simple structure, and the cost of manufacture is low, is favorable to being widely used.
Description
Technical field
The utility model belongs to a kind of refrigerator, concretely relates to the lowering or hoisting gear of the rack that a kind of refrigerator heat-insulation layer uses.
Background technology
At present, the inside at cold compartment of refrigerator is provided with multiple rack for shelving food, and rack is made up of glass plate and frame mostly, and frame is the surrounding that working of plastics is enclosed in glass plate.Being provided with a plurality of courage muscle for supporting rack on the sidewall of cold compartment of refrigerator inner bag, multiple racks are placed on different courage muscle the material-putting space forming differing heights.The refrigerator rack of the overwhelming majority is all that the courage muscle position by both sides adjusts upper and lower distance now, and rack in use, is extracted out from fixing courage muscle by people, then is put on the corresponding courage muscle in the position wanting to place.But when placing large article, space is not enough, when placing less article, have again segment space on the shelf.If it is intended to regulation rack, it is necessary to first the article on rack are taken out, put back to again after adjusting, both inconvenient, also due to open and more electric energy is lost of refrigerator doors long period.With the development of technology, occurring in that the article-holder structure that can lift, the lifting of rack is all completed by elevating mechanism, and user can regulate elevating mechanism as required, so that rack adjusts to required height.Having number of patent application to be 201310461942.5, name of patent application is: adjustable rack for refrigerator and refrigerator；This structure is complicated, and regulation inconvenience, also number of patent application is: 201510290702.2, name of patent application is the structure of the Liftable rack for refrigerator and refrigerator, this structure reaches to lift purpose by gear, the shortcoming equally with complicated structure, and the change for refrigerator is bigger, cost of manufacture is higher.
Utility model content
In view of the presence of problem above, the utility model provides a kind of refrigerator rack lowering or hoisting gear, has simple in construction, cost of manufacture feature low and simple to operate.
A kind of refrigerator rack lowering or hoisting gear, including rack and refrigerator heat-insulation layer, it is characterised in that: in the bottom of described refrigerator heat-insulation layer, the corner that four piston cylinders lay respectively at rack is installed；It is provided with piston in described piston cylinder, one piston rod one end passes through piston cylinder top and is connected with piston, the other end is connected with rack, it is connected to water pipe at the upper and lower two ends of piston cylinder inwall, described water pipe is connected with the water tank of water pump respectively, being provided with positive and negative switch bottom refrigerator heat-insulation layer, described positive and negative switch is connected with power supply and water pump respectively by electric wire.
Preferably: described water pump and water tank are arranged on the inwall bottom heat-insulation layer, it is connected end at piston rod with rack and is provided with sucker.
Preferably: described refrigerator heat-insulation layer two side is provided with vertical slide rail, described rack both sides are respectively arranged with journal stirrup, are provided with pulley on journal stirrup, and described pulley matches with slide rail.
Beneficial effect
The beneficial effects of the utility model are: by the improvement to existing structure, use piston cylinder and piston rod as desired to the height of regulation rack, give and place the enough spaces of big article offer, and simple to operate, easy to control flexibly, this simple in construction, cost of manufacture is low, is conducive to being widely used.
Brief description
Fig. 1 is the structural representation of the utility model rack
Fig. 2 is the structural representation of lowering or hoisting gear in the utility model
Detailed description of the invention
As a kind of embodiment of the present utility model, as shown in Figure 1, 2, a kind of refrigerator rack lowering or hoisting gear, including rack 2 and refrigerator heat-insulation layer, is provided with, in the bottom 3 of described refrigerator heat-insulation layer, the corner that four piston cylinders 1 lay respectively at rack；It is provided with piston 7 in described piston cylinder, one piston rod 6 one end passes through piston cylinder top and is connected with piston, the other end is connected with rack, it is connected to water pipe 4 at the upper and lower two ends of piston cylinder inwall, 8, described water pipe is connected with the water tank of water pump 9 respectively, is provided with positive and negative switch bottom refrigerator heat-insulation layer, and described positive and negative switch is connected with power supply and water pump respectively by electric wire.By arranging piston cylinder and piston rod, and water pump and positive and negative switch are set, water can be injected by switch activated water pump to upper end or the lower end of piston cylinder, forces piston rises or declines, reach to meet the needs of refrigerator, this structure is relative to the simple in construction in the patent application described in background technology, and makes simple cost and also compare relatively low.Owing to being provided with water pump and arranging water tank, antirust agent can be added in water tank or add oil type liquid also can reach identical purpose and be difficult to so that water pump gets rusty in water tank.Piston rod can be made to rise or fall by positive and negative switch simultaneously thus reach arbitrarily to regulate the height of rack, meet different needs.
It in the present embodiment: described water pump and water tank are arranged on the inwall bottom heat-insulation layer, is connected end at piston rod with rack and is provided with sucker 5.Owing to water pump and water tank can arrange very little, so that the too many volume of heat-insulation layer will not be occupied, sucker is set simultaneously and advantageously ensures that stablizing between piston rod and rack, be difficult to slide.
In the present embodiment: described refrigerator heat-insulation layer two side is provided with vertical slide rail, described rack both sides are respectively arranged with journal stirrup, are provided with pulley on journal stirrup, and described pulley matches (not drawing in this part-structure figure figure) with slide rail.The purpose of this structure acts primarily as guide effect, places rack skew.Advantageously ensure that rise and decline slides smoothly.
