[0027] Embodiment 1

[0028] Please refer to Figure 1 The purpose of the present embodiment is to provide a refrigerator door handle decoration strip quick installation device, which comprises a workbench 1, four slide rods 6 are fixedly connected to the lower surface of the workbench 1 near the four corners, sleeve sleeves 7 are slidably arranged on the outer sides of the slide rods 6, the lower ends of the sleeve sleeves 7 contact the ground, so that the workbench 1 can be stably placed on the ground, two air cylinders 2 are symmetrically fixedly connected to the bottom of the workbench 1, the upper ends of the piston rods of the two air cylinders 2 penetrate through the side walls of the workbench 1 and are fixedly connected with pressing plates 3, a cushion block 4 is fixedly connected to the upper surface of the workbench 1, a groove for placing the handle is formed in the upper side of the cushion block 4, the cushion block 4 is arranged directly below the pressing plate 3, after the refrigerator door handle is placed on the cushion block 4, the decoration strip is placed on the refrigerator door handle, and a plurality of clamping blocks on the decoration strip and a plurality of clamping holes on the refrigerator door handle are correspondingly arranged, then the workers control the piston rods of the two air cylinders 2 to be synchronously retracted, so that the piston rods of the air cylinders 2 drive the pressing plates 3 to vertically move downward, when the pressing plates 3 contact the top end of the decoration strip and press the decoration strip downward, the plurality of clamping blocks on the decoration strip are clamped into the plurality of clamping holes on the refrigerator door handle, so as to quickly clamp and fix the decoration strip on the refrigerator door handle, the use of the air cylinders 2 and the pressing plates 3 to assist in installing the decoration strip can save manpower and improve the installation efficiency, and when the clamping blocks are vertically clamped into the clamping holes, the clamping blocks are uniformly stressed, so as to avoid the clamping blocks from being broken due to uneven stress and improve the yield of the door handle.

[0029] When the workers place the decoration strip on the refrigerator door handle, in order to facilitate the plurality of clamping blocks on the decoration strip and the plurality of clamping holes on the refrigerator door handle to correspond to each other, a limiting mechanism 8 is arranged on the upper surface of the workbench 1, the limiting mechanism 8 is arranged on one side of the cushion block 4, and the structure of the limiting mechanism 8 will be described below, please refer to Figure 2 The limiting mechanism 8 comprises a vertical rod 81 fixedly connected to the upper surface of the workbench 1, a baffle 82 slidably arranged on the vertical rod 81, the baffle 82 extends to a position between the cushion block 4 and the pressing plate 3 on one side, a top plate 83 is fixedly connected to the upper end of the vertical rod 81, a plurality of springs 84 are fixedly connected between the baffle 82 and the pressing plate 3, after the workers place the decoration strip on the refrigerator door handle, the baffle 82 contacts one side of the decoration strip, the baffle 82 blocks the horizontal movement of the decoration strip towards the vertical rod 81, so as to limit the placement position of the decoration strip on the refrigerator door handle and help the workers to move the clamping blocks on the decoration strip to the positions corresponding to the clamping holes on the refrigerator door handle, thereby improving the efficiency of the workers in pressing and assembling the decoration strip by using the pressing plate 3.

[0030] The worker places the refrigerator door handle on the cushion block 4, and when placing the decorative strip on the refrigerator door handle, the worker needs to stand on one side of the workbench 1 to operate. Because different workers have different heights, workers who are taller or shorter are prone to fatigue when operating on the workbench 1 that is not suitable in height, which reduces the work efficiency of the workers. To solve this problem, the mounting plate 72 is fixedly arranged between the four sleeves 7, and the lifting mechanism 5 is arranged at the top of the mounting plate 72. The lifting mechanism 5 is used to drive the sliding rod 6 to slide along the inner wall of the sleeve 7, so as to adjust the height of the workbench 1. The structure of the lifting mechanism 5 will be refined below with reference to Figures 3-6 The lifting mechanism 5 includes a hydraulic cylinder 51 fixedly arranged at the bottom of the mounting plate 72. The upper end of the piston rod of the hydraulic cylinder 51 penetrates through the side wall of the mounting plate 72 and is fixedly connected with an end plate 52. Two racks 53 are fixedly and symmetrically connected on both sides of the end plate 52. Two extension rods 54 are symmetrically and rotatably connected to the upper surface of the mounting plate 72. A gear 55 is coaxially and fixedly connected to the side wall of the extension rod 54. The two gears 55 are meshed with the two racks 53, respectively. When the piston rod of the hydraulic cylinder 51 extends or retracts to vertically move the end plate 52, the end plate 52 drives the two racks 53 to move synchronously. Through the meshing transmission of the rack 53 and the gear 55, the gear 55 drives the extension rod 54 to rotate. The side wall of the sleeve 7 is provided with a movable groove 71, and the two ends of the extension rod 54 extend to the outside of the workbench 1 and are fixedly connected with a rotating plate 56. The middle segments of the four rotating plates 56 are arranged inside the four movable grooves 71, respectively. Meanwhile, a sliding groove 57 is arranged at the end of the rotating plate 56 away from the extension rod 54. An installation groove is arranged at the bottom of the sliding rod 6, and a rotating column 61 is rotatably connected to the position close to the bottom inside the installation groove. One end of the rotating plate 56 is arranged in the installation groove, and the rotating column 61 is slidingly arranged inside the sliding groove 57. When the extension rod 54 drives the rotating plate 56 to rotate upward, the rotating plate 56 pushes the rotating column 61, so that the rotating column 61 is subjected to an upward force. The stressed rotating column 61 drives the sliding rod 6 to move upward. The sliding rod 6 vertically slides in the sleeve 7, and the rotating column 61 slides in the sliding groove 57. The height of the workbench 1 is adjusted by the vertical upward sliding of the sliding rod 6 in the sleeve 7. Similarly, when the extension rod 54 drives the rotating plate 56 to rotate downward, the height of the workbench 1 can be adjusted. The worker adjusts the height of the workbench 1 according to his own height, so that the worker can operate on the workbench 1 with appropriate height, and the worker is not prone to fatigue to reduce the work efficiency.
