Refer to Fig. 1 and Fig. 2, the utility model relates to a kind of liftable showcase, comprises cabinet 1, cabinet seat 2 and carriage assembly 3, and described cabinet 1 is offered form 11 on front cabinet wall, and the rear cabinet wall of cabinet 1 is made up of biparting live body sliding door; Described cabinet seat 2 is positioned at the bottom of cabinet 1, and the bottom of cabinet seat 2 is provided with four universal wheels 22.Described carriage assembly 3 is arranged in the cabinet chamber of cabinet 1.Carriage assembly 3 comprises slide rail 31 and movable bracket 32, and described slide rail 31 has a pair of, the middle part of the short transverse of the left and right sidewall of the cabinet 1 described in being set in parallel in that faces each other; Described movable bracket 32 is made up of a pair of left side plate 321 and at least one supporting plate 322, has illustrated in the present embodiment two-layer supporting plate 322.Described left side plate 321, respectively in the side towards cabinet 1 left and right sidewall, is offered for the lifting chute 3211 for slide rail 31 insertings along short transverse.Described cabinet 1 is also provided with lowering or hoisting gear 4 in cabinet chamber, and described lowering or hoisting gear 4 is positioned at the below of movable bracket 32 short transverses and fixedly mounts with cabinet seat 2, and lowering or hoisting gear 4 is in transmission connection with movable bracket 32.Described lowering or hoisting gear 4 comprises hollow box 41, eccentric wheel 42, reduction gearing 43, lifting motor 44, crane 45 and support 46.Described eccentric wheel 42 is inlaid in the die cavity of hollow box 41, its excircle contacts with epicoele wall and the cavity of resorption wall of hollow box 41 rotationally, eccentric wheel 42 is in transmission connection by bearing block and reduction gearing 43, reduction gearing 43 engages with the lifting drive gear 441 of lifting motor 44, and lifting motor 44 is fixed on cabinet seat 2.The case chamber 21 of doing elevating movement for holding hollow box 41 is offered in the position of described cabinet seat 2 under corresponding movable bracket 32.Described crane 45 be in transmission connection hollow box 41 and movable bracket 32, make movable bracket 32 slide up and down along slide rail 31 by the power of hollow box 41 by lifting action, realizes thus rising or the decline of supporting plate 322.Particularly, described crane 45 comprises cross frames 451, upper slide rail 452 and glidepath 453, described cross frames 451 comprises two connecting rods 4511 and a rod 4512, two described connecting rods 4511 are arranged in a crossed manner, and the middle part at length direction arranges connecting hole 45111 in interval symmetrically, connecting hole 45111 corresponding on two connecting rods 4511 is passed successively to realize the flexible connection of two connecting rods 4511 in one end of a described rod 4512, and the other end of a rod 4512 is fixedly connected with support 46.Described upper slide rail 452 is installed in the bottom of movable bracket 32 short transverses, and upper slide rail 452 is offered the first chute 4521 at length direction, and two upper ends of cross frames 451 are inlaid in the first chute 4521 slidingly; Described glidepath 453 is installed on hollow box 41, and glidepath 453 is offered the second chute 4531 at length direction, and two lower ends of cross frames 451 are inlaid in the second chute 4531 slidingly.Described lowering or hoisting gear 4 also comprises limit switch 47, and described limit switch 47 is arranged on described cabinet seat 2 and is positioned at the below of glidepath 453, for coordinating and carry out descending spacing with glidepath 453.
Refer to Fig. 3, prop up the position of the connecting hole 45111 that rod 4512 inserts by change, the lifting height of adjustable cross frames 451, thereby the heave amplitude of adjustable bracket 32.In figure, illustrate two kinds of location status of a connecting rod 4511, supposed: the length of connecting rod 4511 is L (not shown); Propping up rod 4512 is O with the crosspoint of connecting rod 4511, and O point is l to the length of connecting rod 4511 lower ends, and O point is s to the distance of glidepath 453, and the difference in height of eccentric wheel 42 peaks and minimum point is h; In position for the moment, O point is H1 to the distance of movable bracket 32 to connecting rod 4511, and connecting rod 4511 is in the time of position two, and O point is H2 to the distance of movable bracket 32,
(α is the angle of connecting rod 4511 between one place, position and vertical line) (1)
(α is the angle of connecting rod 4511 between two places, position and vertical line) (2) can be obtained by formula (1) and formula (2)
In formula (3), because L and h are definite value, therefore change the numerical values recited of l, can make the numerical value of H change, thereby reach the object that regulates movable bracket 32 heave amplitudes.
Please continue to refer to Fig. 1 and Fig. 2, described lifting motor 44 is with movable eccentric wheel 42 to rotate through reduction gearing 43, and eccentric wheel 42 drives that hollow box 41 is interior in case chamber 21 does elevating movement.When eccentric wheel 42 rotates be positioned under (bias) axle center during to its center of circle, the cavity of resorption wall application of force of eccentric wheel 42 to hollow box 41, hollow box 41 is sunk, in this process, cross frames 451 is owing to linking with hollow box 41, taking a rod 4512 as fulcrum, two ends is come closer respectively along the second chute 4531 of glidepath 453 along the first chute 4521 of upper slide rail 452, lower two ends, drive movable bracket 32 to rise.In the time that hollow box 41 sinks down into lowest order, glidepath 453 coordinates with limit switch 47, makes lifting motor 44 stalls, and now movable bracket 32 maintains highest order, flushes with form 11, carries out showpiece displaying.Otherwise, when eccentric wheel 42 rotates be positioned at directly over (bias) axle center during to its center of circle, the epicoele wall application of force of eccentric wheel 42 to hollow box 41, make hollow box 41 increase, cross frames 451 links with hollow box 41, taking a rod 4512 as fulcrum, two ends is outwards separated respectively along the second chute 4531 of glidepath 453 along the first chute 4521 of upper slide rail 452, lower two ends, drive movable bracket 32 to decline.User can adjust the amplitude that movable bracket 32 rises or declines according to the actual height of cabinet 1 and the convenience self arranging exhibits.Limit switch 47 coordinates to control the operation that lifting motor 44 turns round with glidepath 453, specifically can realize by single-chip microcomputer or PLC, in the present embodiment, has adopted PLC, and concrete model is Delta DVP20EC.Refer to Fig. 4, the X7 end of described PLC connects one end, the X12 of button at the beginning and holds the one end, the X10 that connect a stop button to hold the one end that connects limit switch 47, jointly connect+24 ends of the other end of the other end of start button, the other end of stop button and limit switch 47, L, the N end of PLC connects external ac power source, and C1 end, the Y4 end of PLC connect lifting motor 44.PLC, by operation start button, stop button and limit switch 47, realizes the control to lifting motor 44.This PLC also can carry out time control by its inner time relay, after movable bracket 32 rising certain hours, makes lifting motor 44 stalls.Above-mentioned application is the known technology of this PLC, no longer specifically repeats.
