Description of the invention: [Technical field to which the invention pertains] The invention relates to a trolley, and more particularly to a trolley having a lifting (four). [Prior Art] _] In the field of product manufacturing, it is necessary to transport workpieces weighing 4 to 4 and place them on cabinets with a fixed height, such as molds. Because the weight of the workpiece is heavier, it is not convenient for the guard to manually transport the guard to the machine. The technique is mainly to make the transport and handling of the piece 1. The use of the car has higher requirements on the skill of the worker. Damage to the workpiece caused by mistakes. And the car, so it can not be applied in many occasions » 〇 .. II. [Invention content] [_ (four) minus, it is necessary to provide _ (four) cart, convenient for the guard to place the workpiece in a cabinet with a certain height. The support frame and the dry tray, the support_the bottom is fixed with a chat wheel for placing or carrying the χ , , , , , , , , , , , , , , , , , , , , , , , , , , , The transmission mechanism is configured to transmit the movement of the drive mechanism to drive the secret disk to slide relative to the support frame. _5] Using the trolley to transport the guards, it can solve the above problems financially, so it is convenient for workers to use. [Embodiment] [0006] 100103187 Please refer to FIG. 1 and FIG. 2 together, the hand push W includes a support frame, a support form number A0101, page 3/15 pages, 1002005646-0 201231334 disk 20, a drive Mechanism 30 and a transmission mechanism 4〇. The tray 2 is slidably disposed on the support frame 10 for placing a workpiece. The drive mechanism 3 and the transmission mechanism 40 are respectively used to drive and position the tray 20, thereby facilitating placement of the workpiece on a cabinet having a specific height. [00〇7] Referring to FIG. 3, the support frame 10 includes a top n, a bottom 12, and four vertical rods 13 and two positioning rods 14 therebetween. Two sides of the top portion 11 are respectively provided with two fixed pulleys 15'. The bottom portion 12 is provided with four casters 16. The four vertical rods 13 and the two positioning rods 14 are parallel to each other and form a square receiving space, and the four vertical rods 13 are oppositely disposed with the sliding grooves 17 extending along the longitudinal direction thereof. The support frame 1 also includes a push rod 18 fixed to the vertical rod 13 for facilitating the user to push the support frame 1 to slide. Referring to FIG. 4, the tray 20 has a rectangular plate shape, and the tray 20 is composed of a first link 21, a second link 22, a third link 23, and a fourth link 24 which are sequentially fixedly connected. Wherein the first link 21 is parallel to the third link 23, and the second link 22 is parallel to the fourth link 24. A horizontal plate 25 and a plurality of support rods 26 are further disposed between the first link 21 and the third link 23. The support rod 26 is used to support or place the workpiece. : | Home - link 21, second link 22 and third link 23 on the raised baffle 27' for preventing the workpiece from slipping out of the tray 20. The tray 20 is slidably disposed between the four vertical rods 13, and the chutes 17 of each of the male straight rods 13 are provided with two side by side sleeves 28. The two bearings 28 are snapped into the above-described chute 17, so that the tray 20 can smoothly slide along the chute 17. A positioning block 29 is detachably fixed to the end of the first link 21 and the third link 23 adjacent to the fourth link 24, and the positioning block 29 is substantially L-shaped. As shown in the figure, the positioning block 29 on the right side can prevent the workpiece from slipping out from the fourth link 24. The left side positioning block 2 can not be 100103187. Form number A0101 Page 4 / Total 15 pages 1002005646-0 201231334 The workpiece slides out of the fourth link 24. [0009] Referring to FIG. 1 and FIG. 2, the driving mechanism 3 includes an electric motor 31 and a frequency converter 32 fixed to the support frame 10. The motor 31 includes a main body 311, a first pulley 312, a control switch 314, and a handle 313. The handle 313 can control the rotation of the first pulley 312 for manual trimming and power failure. The control switch 314 is used to control the rotation of the first pulley 312 on the motor 31, including its rotation direction, torque and Rotating speed. The frequency converter 32 is coupled to the motor 31 for effecting the variable speed of the motor 31. Referring to Fig. 5, the transmission mechanism 40 includes a lead screw 41, a cymbal lift plate 42, and two connecting cords 43. The lead screw 41 includes a cymbal 4U and a second pulley 412 that are fixed to each other. The second pulley 412 is rotatably coupled to the first pulley 312 by a belt 413. In the present embodiment, the radius of the > pulley 412 is larger than the radius of the first pulley 312. The lifting plate 42 includes a sleeve 42 for the two positioning rods 14 of the support frame 10, and the lifting plate 42 further includes a nut 423, which is inserted through the screw 41, and the wire cup 41 The nut 4 23 constitutes a nut screw pair. Thereby, the lift plate 42 can slide along the positioning rod 14 and the lead screw 41 when the lead screw 41 rotates. One end of the speed cord 43 is fixed on the horizontal plate 25 of the tray 20, and the other end is fastened to the lifting plate 42 after bypassing the two fixed pulleys 15" [0011] After the dressing is completed, the tray 2 is located at the above support When the motor 31 is operated to drive the screw 41 to rotate between the four rafts 1 of the frame 10, the slab 42 can slide along the two positioning rods 14 and the lead screw 4, thereby driving the tray 20 to move up and down. Thus, the cart 1 can facilitate the placement of the > piece on a cabinet having a certain height. 100103187 Form No. A0101 Page 5 of 15 1002005646-0 201231334 [Brief Description of the Drawings] [0012] Fig. 1 is a perspective view of a cart having a lifting tray in accordance with a preferred embodiment of the present invention. 2 is a perspective view of another opposite perspective view of the cart shown in FIG. 1. 3 is a perspective view of the trolley support frame shown in FIG. 1. 4 is a perspective view of the cart tray shown in FIG. 1.
