Description

Technical Field

[0001] The present invention relates to the technical field of logistics express item placement racks, and in particular to an automatic lifting placement rack for logistics express items. Background Art

[0002] Logistics express parcels refer to various parcels and items that are handled and transported during the logistics and express delivery process. In order to avoid the mess caused by the express parcels being piled on the ground, a display rack is usually used to place the express parcels so that the express parcels are placed in an orderly manner. In order to enable the staff to easily adjust the height of the goods and quickly pick up and place the parcels, the display rack is usually set to an automatic lifting type.

[0003] After searching, the Chinese patent "A courier rack for logistics companies that is convenient for picking up goods" authorization announcement number "CN217836639U" realizes pushing the express items on the courier rack to the edge through a second electric push rod, a mounting plate, a picking part and a push plate, making it easier to pick up the express items at a high position on the courier rack.

[0004] The above method only pushes the express items to the edge of the express rack, which still makes it inconvenient for the staff to take or store the express items at the height of the express rack, thereby reducing the practicality of the display rack.

[0005] Therefore, an automatic lifting and placing rack for logistics express items is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide an automatic lifting and placing rack for logistics express parcels in order to solve the above-mentioned problems, thereby improving the inconvenience that workers still encounter when taking or storing express parcels at the height of the express rack.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: an automatic lifting and placing rack for logistics express items, comprising: a placing rack, wherein the upper end of the inner wall of the placing rack is slidably connected to a plurality of first placing frames, and the lower end of the inner wall of the placing rack is fixedly connected to a plurality of second placing frames; a lifting mechanism, wherein the lifting mechanism is arranged on the surface of the placing rack; wherein the lifting mechanism comprises a sliding frame fixedly connected to both sides of the placing rack, the inner wall of the sliding frame is slidably connected to a slider, the inner wall of one of the sliding frames is rotatably connected to a screw rod, the inner wall of one of the sliders is threadedly connected to the surface of the screw rod, the surface of the screw rod is fixedly connected to a servo motor, the surface of the servo motor is fixedly connected to the rear end of one of the sliding frames, and the inner wall of the slider is slidably connected to a connecting rack. By using the connecting rack, the connecting rack is clamped in one of the first placing frames and the first placing frame is away from the inner wall of the placing rack, and by using the servo motor, the screw rod and the slider, one of the first placing frames is automatically moved downward, which is convenient for taking or storing express items at a height on the placing rack, and improves the practicality of the placing rack.

[0008] Preferably, the inner wall of the connecting frame is slidably connected with a positioning frame, and the upper surface of the positioning frame is clamped on the inner wall of one of the first frames. The positioning frame is used to ensure the stability of the connecting frame in one of the frames, thereby ensuring that the lateral movement of the connecting frame can drive the lateral movement of one of the first frames.

[0009] Preferably, the bottom of the positioning frame is fixedly connected with spring pieces distributed in equal rows, and the bottom ends of the spring pieces are fixedly connected to the inner bottom wall of the connecting frame.

The connecting plate, the stopper and the spring sheet are used to stably clamp the positioning frame in one of the first frames, thereby ensuring the stability of the connection between the connecting frame and the first frame.

[0012] Preferably, a stopper is fixedly connected to the rear end of the rack, and the rear end of the first frame contacts the front end of the stopper. The stopper is used to limit the moving distance of the first frame on the rack, and prevent the first frame from escaping from the inner wall of the rack during movement.

[0013] Preferably, a retaining ring is fixedly connected to the surface of the connecting frame. The retaining ring is used to limit the moving distance of the connecting frame in one of the first placing frames, ensuring that the positioning frame can be accurately stuck in one of the first placing frames.

[0014] Preferably, an inner wall of one of the sliding frames is slidably connected to a limiting block.

[0015] Preferably, a fixing block is fixedly connected to the upper end of the inner wall of one of the sliding frames. The fixing block and the limit block are used to limit the moving distance of the connecting frame, ensuring that the connecting frame can be accurately stuck in one of the first placing frames.

[0016] Preferably, a front end of one of the sliding frames is fixedly connected to a limiting rod, and the inner wall of the limiting block is slidably connected to the surface of the limiting rod. The limiting rod is used to limit the moving distance of the front end of the limiting block, thereby preventing the limiting block from being lost.

[0017] The beneficial effects of the present invention are:

[0018] 1. The connecting frame is used to connect the connecting frame to one of the first placing frames and keep the first placing frame away from the inner wall of the placing frame. The servo motor, the screw rod and the slider are used to automatically move one of the first placing frames downward, so as to facilitate the picking up or storage of express items at the height of the placing frame, thereby improving the practicality of the placing frame.

[0019] 2. The positioning frame is used to ensure that the connecting frame is stably stuck in one of the frames, thereby ensuring that the lateral movement of the connecting frame can drive one of the first frames to move lateraly. The connecting plate, the stop block and the spring sheet are used to ensure that the positioning frame is stably stuck in one of the first frames, thereby ensuring the stability of the connection between the connecting frame and the first frame.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] When implementing: Figure 1-4 As shown, an automatic lifting and placing rack for logistics express items includes: a placing rack 1, a plurality of first placing frames 2 are slidably connected to the upper end of the inner wall of the placing rack 1, and a plurality of second placing frames 4 are fixedly connected to the lower end of the inner wall of the placing rack 1; a lifting mechanism 3, the lifting mechanism 3 is arranged on the surface of the placing rack 1; wherein the lifting mechanism 3 includes a sliding frame 31 fixedly connected to both sides of the placing rack 1, a slider 32 is slidably connected to the inner wall of the sliding frame 31, a screw rod 33 is rotatably connected to the inner wall of one of the sliding frames 31, an inner wall of one of the sliders 32 is threadedly connected to the surface of the screw rod 33, a servo motor 34 is fixedly connected to the surface of the screw rod 33, a surface of the servo motor 34 is fixedly connected to the rear end of one of the sliding frames 31, and a connecting frame 35 is slidably connected to the inner wall of the slider 32.

[0027] like Figure 3As shown, the inner wall of the connecting frame 35 is slidably connected with a positioning frame 36, the upper end of the surface of the positioning frame 36 is clamped on the inner wall of one of the first placing frames 2, the bottom of the positioning frame 36 is fixedly connected with spring pieces 37 distributed in an equal column, the bottom end of the spring pieces 37 is fixedly connected to the inner bottom wall of the connecting frame 35, the front end of the connecting frame 35 is fixedly connected with a connecting plate 39, the lower end of the surface of the positioning frame 36 is slidably connected with a stop block 38, and the bottom of the stop block 38 contacts the top of the connecting plate 39.

[0028] When it is necessary to pick up the express on the high place of the placement rack 1, the servo motor 34 is manually turned on, and the output shaft of the servo motor 34 rotates to drive the screw rod 33 to rotate, and the screw rod 33 rotates to drive the slider 32 and the connecting frame 35 to move up to a suitable position, and the servo motor 34 is manually turned off to push the connecting frame 35, and the connecting frame 35 moves into one of the first placement frames 2. The elastic force of the spring piece 37 pushes the positioning frame 36 to move up and get stuck in one of the first placement frames 2, and pushes the stop block 38 to make it move in the positioning frame 36 so that the bottom of the stop block 38 contacts the top of the connecting plate 39. At this time, the connecting frame 35 is pulled, and the connecting frame 35 moves horizontally to drive one of the first placement frames 2 to move horizontally out of the placement rack 1, and the servo motor 34 is manually turned on. The output shaft of the servo motor 34 rotates through the slider 32 and the screw rod 33 to drive the connecting frame 35 and one of the first placement frames 2 to move down to a suitable position, and the express in the first placement frame 2 is taken.

[0029] like Figure 2 As shown, the rear end of the placement rack 1 is fixedly connected with a stopper 313 , and the rear end of the first placement frame 2 contacts the front end of the stopper 313 .

[0030] After taking is completed, the servo motor 34 is manually turned on, and the output shaft of the servo motor 34 rotates through the screw rod 33 to drive the slider 32, the connecting frame 35 and one of the first placing frames 2 to move to the appropriate position, and the servo motor 34 is manually turned off, and the connecting frame 35 is pushed to make the connecting frame 35 move in the slider 32 and drive one of the first placing frames 2 to move in the placing frame 1 and hit the front end of the stop block 313, and the pushing of the connecting frame 35 stops.

[0031] like Figure 3-4 As shown, a retaining ring 312 is fixedly connected to the surface of the connecting frame 35, the inner wall of one of the sliding frames 31 is slidably connected to the limiting block 310, the upper end of the inner wall of one of the sliding frames 31 is fixedly connected to a fixing block, the front end of one of the sliding frames 31 is fixedly connected to the limiting rod 311, and the inner wall of the limiting block 310 is slidably connected to the surface of the limiting rod 311.

[0032] When the present invention is in use, one of the limit blocks 310 is pushed to move into one of the slide frames 31, and the servo motor 34 is manually turned on. The output shaft of the servo motor 34 rotates through the screw rod 33 to drive the slider 32 and the connecting frame 35 to move upward. When the top of the slider 32 abuts against the bottom of one of the limit blocks 310, the servo motor 34 is manually turned off, and the connecting frame 35 is pushed. The connecting frame 35 moves into one of the first placing frames 2, and the retaining ring 312 on the connecting frame 35 moves to abut against the front end of the slider 32, and the pushing of the connecting frame 35 stops, and the spring 37 is released. The force pushes the positioning frame 36 upward and gets stuck in one of the first placing frames 2, pushing the stop block 38 to make it move in the positioning frame 36, so that the bottom of the stop block 38 abuts against the top of the connecting plate 39. At this time, the connecting frame 35 is pulled, and the connecting frame 35 moves horizontally to drive one of the first placing frames 2 to move horizontally out of the placing frame 1. The servo motor 34 is manually turned on, and the output shaft of the servo motor 34 rotates through the screw rod 33 to drive the slider 32, the connecting frame 35 and one of the first placing frames 2 to move down to a suitable position. At this time, the express items in the first placing frame 2 are taken out.

[0033] It should be noted that the placement rack 1, the first placement frame 2, the second placement frame 4, the servo motor 34 and the spring 37 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 34 can be powered by a built-in power supply or by AC power.
