Abstract

A manual lifting microcomputer worktable comprises a lifting platform (4), a swaying tray (2) with a handle (1) at a little higher part outside the lifting platform is connected on the side wall of the lifting platform (4) via an axis (3) and a fixing pedestal (5). The utility model is characterized in that a buck plate (12) is fixed on the side wall of the lifting platform (4) with an intermediate wheel (11) arranged on; while a drive wheel buck plate (16) and a support drive wheel (14) are also arranged on the side wall, and a crank connecting rod (10) is assembled in the center of the drive wheel (14), the crank connecting rod (10) is articulated with the lower end of a handspike (9), the upper end of which is articulated with a microcomputer splint (7) via an axis pin (8) ; a wind steel wire (6) is fixed on the axis (3), runs round the lower part of the drive wheel (14) to the back of the intermediate wheel (11) fixed on the buck plate (12), and is fixed on the crank connecting rod (10). The utility model has the advantages that silent microcomputer lifting can be reached by moving a wheel axle, and labor is saved, thus being especially suitable for operation in schools and comparatively open microcomputer classrooms. The utility model has better effects if being matched with a microcomputer lifting worktable with a Chinese patent number of 00247580.4.

Description

A kind of artificial lifting microcomputer workbench

Technical field the utility model belongs to furniture, particularly is exclusively used in the device of microcomputer worktable lifting.

Background technology has the workbench of microcomputer elevating function at present, a kind of microcomputer self-powered platform that has only the Chinese patent 00247580.4 of designer's proposition of the present utility model, this workbench, because limitation of design at that time, needing bigger strength during hand-operated lifting can lifting, has influenced use.And there are phenomenons such as structure more complicated.Through the exploitation of the continuation more than 2 years, structure of the present utility model has been proposed, improve the deficiency that hand-operated lifting exists, a kind of artificial lifting microcomputer workbench is provided.

This artificial lifting microcomputer workbench of summary of the invention, this workbench comprises a crane [4], the outside of crane slightly has a shaking tray [2] with handle [1] to be fixed on the sidewall of crane [4] by axle [3] and holder [5] by top, it is characterized in that supporting plate [12] is fixed on the sidewall of crane [4], assembling an idle wheel [11] on it, on sidewall, also has driving wheel supporting plate [16], support driving wheel [14], driving wheel [14] center assembling crank connecting link [10], this crank connecting link [10] and upper end are hinged by the lower end of the push rod [9] that bearing pin [8] and microcomputer supporting plate [7] are hinged, go up fixing wound steel wire rope [6] at axle [3], this steel wire rope [6] below driving wheel [14], walk around idle wheel [11] on being fixed on supporting plate [12] above after be fixed on the crank connecting link [10].Its advantage is the motion by wheel shaft, can realize noiseless lifting microcomputer, and more laborsaving, uses in the microcomputer classroom of be particularly suitable for school, relatively opening.The special a kind of microcomputer self-powered platform result of use of Chinese patent 00247580.4 that cooperates is better.

Appended drawings 1 is a main TV structure schematic diagram of the present utility model, and accompanying drawing 2 is left side views of accompanying drawing 1, and the sequence number of parts is in the accompanying drawings: 1, handle, 2, shaking tray, 3, axle, 4, crane, 5, holder, 6 steel wire ropes,, 7, microcomputer supporting plate, 8, bearing pin, 9, push rod, 10, crank connecting link, 11, idle wheel, 12, supporting plate, 13, screw, 14, driving wheel, 15, screw, 16, driving wheel supporting plate, 17, the supporting plate connecting plate, 18, balladeur train.

The specific embodiment is with reference to accompanying drawing, and this workbench comprises a crane [4], and its mounted inside has a balladeur train that can slide up and down [18], cooperates the supporting plate [7] that supports microcomputer above this balladeur train [18].The outside of crane slightly has a shaking tray [2] with handle [1] to be fixed on the sidewall of crane [4] by holder [5] by axle [3] by top, supporting plate [12] is fixed on the sidewall of crane [4] by one group of screw [13], and an idle wheel [11] is being assembled on its top.On sidewall, also has driving wheel supporting plate [16], this driving wheel supporting plate is fixed on the sidewall by one group of screw [15], support driving wheel [14], driving wheel [14] center assembling crank connecting link [10], this crank connecting link [10] and upper end are hinged by the lower end of the push rod [9] that bearing pin [8] and microcomputer supporting plate [7] are hinged, go up fixing wound steel wire rope [6] at axle [3], this steel wire rope [6] below driving wheel [14], walk around idle wheel [11] on being fixed on supporting plate [12] above after be fixed on the crank connecting link [10].In order to increase the intensity of supporting plate [12], designed supporting plate connecting plate [17], be connected on driving wheel supporting plate [16] and the supporting plate [12].Position in the accompanying drawing is the operating position that is raised to peak, when needs put down, turning handle [1] loosens steel wire rope [6], and crank connecting link has lost pulling force on [10], at this moment, push rod [9] balladeur train [18] and microcomputer supporting plate [7] with and on the gravity effect of load-bearing (microcomputer) under, together to lower slider, drive crank connecting link [10] around the downward swing of driving wheel axle bed, put in place up to the balladeur train lower slider, stop.When needing to rise, with decline rightabout turning handle [1], the steel wire rope [6] that is fixed on the axle [3] is wound on the axle [3] thereupon, the other end of steel wire rope is fixed on the crank connecting link, the tension crank connecting link, be rotated further this moment, and then steel wire rope [6] just spurs crank connecting link [10] and upwards puts along drive sprocket axle, drive push rod [9] simultaneously and upwards microcomputer supporting plate [7] and balladeur train [18] are upwards slided, up to getting back to the operating position.
