Description

Technical Field

[0001] The present invention relates to the technical field of storage, and in particular to a flexible, efficient, labor-saving and intelligent compact shelving. Background Art

[0002] Intelligent compact shelving is a type of compact shelving that integrates manual and electric control. It can be operated from a distance, and the transmission modes are independent and do not affect each other. Traditional compact shelving has a fixed transmission ratio, which will cause a sense of frustration when starting and stopping, and has a slow response speed and poor controllability, making it more difficult for operators to manually adjust the compact shelving.

[0003] It can be seen from the above-mentioned compact racks that there are still the following defects:

[0004] 1. Due to the fixed transmission ratio of the intelligent compact shelving, there will be a sense of frustration when the compact shelving needs to be moved, which may easily cause the items inside the compact shelving to scatter, and the transmission ratio cannot be adjusted in real time according to different internal loads to provide better controllability. When the transmission ratio cannot be changed according to changes in load, it is easy to cause the equipment to not operate in the optimal state.

[0005] 2. When the intelligent compact shelving moves to the end of the slide rail, it needs to be moved in the opposite direction to move the compact shelving back to its original position. If the operator does not rotate it in the opposite direction in time, the bottom of the compact shelving will continue to rub against the end of the track, which will increase the wear of the bottom pulley and shorten its service life. It will also cause the bottom of the compact shelving to collide with the end of the slide rail, causing the compact shelving to shake and increasing the risk of items inside the compact shelving falling and being damaged.

[0006] Therefore, the present invention proposes a flexible, efficient, labor-saving and intelligent compact shelving to make up for and improve the shortcomings of the existing technology. Summary of the Invention

[0042] refer to Figure 5 and Figure 8 As shown, a flexible, efficient, and labor-saving intelligent compact rack, the automatic reversing mechanism 3 includes a tooth piece 1 31 fixedly connected to the outer surface of the rotating shaft 1 227, the outer surface of the tooth piece 1 31 is meshed with a tooth piece 2 311, the center of the tooth piece 2 311 is fixedly connected to the rotating shaft 2 312, the outer surface of the rotating shaft 2 312 close to the tooth piece 2 311 is fixedly connected to a saw gear 1 313, the saw gear 1 313 is composed of an internal gear and a sliding sleeve slidably connected to the outer surface of the gear, and the saw gear 1 313 is away from the rotating shaft 2 312.

The outer surface of rotating shaft 1 227 close to tooth plate 1 31 is fixedly connected to saw gear 3 315.

[0043] The automatic reversing mechanism 3 further comprises an L-shaped column 32 fixedly connected to the side plate 13 near the second tooth piece 311, the bottom of the L-shaped column 32 is rotatably connected to a transmission bar 321, the end of the transmission bar 321 near the saw gear 1 313 is rotatably connected to a transmission rod 1 322, the top of the transmission rod 1 322 is fixedly connected to a sliding sleeve on the outer surface of the saw gear 1 313, the upper surface of the other end of the transmission bar 321 is rotatably connected to the transmission rod 2 323, the top of the transmission rod 2 323 is fixedly connected to the sliding sleeve on the outer surface of the saw gear 3 15, the side of the transmission bar 321 away from the side plate 13 is fixedly connected to a swing bar 324, the lower surface of the swing bar 324 is fixedly connected to a fixed column 1 325, and the outer surface of the fixed column 1 325 is fixedly connected There is a spring 326, and both sides of the bottom surface of the L-shaped column 32 are fixedly connected to the limit columns 327.

[0044] The effects of this embodiment are as follows: In the prior art, when the intelligent compact shelving moves to the end of the slide rail, it needs to move in the opposite direction to move the compact shelving back to its original position. When the operator fails to rotate in the opposite direction in time, the bottom of the compact shelving will continue to rub against the end of the track, which will increase the wear of the bottom pulley 14 and shorten its service life. Compared with the prior art, the swing bar 324 at the bottom of the compact shelving swings back and forth, so that when the compact shelving moves to the end of the slide rail, it can move in the same direction again without additional operation, and the moving direction of the compact shelving can be automatically changed, making the movement of the compact shelving smoother and more efficient.

[0045] The complete working principle and steps of the above embodiment are as follows:

[0046] Steps of continuously variable transmission:

[0047] like Figure 3 and Figure 4 As shown, when the compact rack is in the initial state, the output shaft of the micro cylinder 1 212 is in the contracted state, and the output shaft of the micro cylinder 2 223 is in the output state;

[0048] When the staff needs to move the compact shelving, the staff first rotates the crank 211 counterclockwise, and as the V-shaped turntable 3 221 rotates counterclockwise, the driving shaft 21 is driven to rotate at the same time, and then the micro cylinder 1 212, V-shaped turntable 1 213 and V-shaped turntable 2 214 on the outer surface of the driving shaft 21 are driven to rotate at the same time. When the V-shaped turntable 1 213 and V-shaped turntable 2 214 rotate counterclockwise, the inner synchronous belt 22 is driven to rotate at the same time. As the synchronous belt 22 rotates counterclockwise, the V-shaped turntable 3 221 and V-shaped turntable 4 222 on both sides are driven to rotate at the same time. As the V-shaped turntable 3 221 and V-shaped turntable 4 222 rotate counterclockwise, the micro cylinder 2 223 at the center of the V-shaped turntable 4 222 is driven to rotate at the same time. The counterclockwise rotation of cylinder 223 drives the internal fixed driven shaft 224 to rotate simultaneously. When the driven shaft 224 rotates counterclockwise, it drives the toothed disc 225 fixedly connected to the outer surface of the driven shaft 224 to rotate simultaneously. The toothed disc 225 rotates counterclockwise and drives the driven disc 226 to rotate simultaneously through the chain transmission. As the driven disc 226 rotates counterclockwise, it drives the rotating shaft 1 227 to rotate simultaneously. At this time, micro cylinder 1 212 and micro cylinder 2 223 are still in the untriggered state. The gap between V-shaped turntable 1 213 and V-shaped turntable 2 214 is smaller than the gap between V-shaped turntable 3 221 and V-shaped turntable 4 222. The transmission track of the synchronous belt 22 is on the inner edge of the inclined surface of V-shaped turntable 1 213 and V-shaped turntable 2 214. The distance between the V-shaped turntable 3 221 and the V-shaped turntable 4 222 is larger than the gap between the V-shaped turntable 1 213 and the V-shaped turntable 2 214. The transmission track of the synchronous belt 22 is on the outer edge of the inclined surface of the V-shaped turntable 3 221 and the V-shaped turntable 4 222. The working half is larger than that of the V-shaped turntable 1 213 and the V-shaped turntable 2 214. The small wheel drives the large wheel transmission to obtain enough torque to overcome the resistance and drive the entire compact rack to move. As the rotation increases, the output shaft of the micro cylinder 1 212 will gradually drive the V-shaped turntable 1 213 to move toward the side close to the V-shaped turntable 2 214, and the output shaft of the driven shaft 224 will gradually drive the V-shaped turntable 4 222 to move away from the V-shaped turntable 3 221. The working diameter between 3 and V-shaped turntable 214 gradually increases, and the working diameter between V-shaped turntable 3 221 and V-shaped turntable 4 222 gradually decreases. The large wheel drives the small wheel to rotate, and the speed ratio also decreases accordingly. When the staff stops rotating, the driving shaft 21 and the driven shaft 224 return to the initial state, and the transmission ratio also returns to the initial state. The transmission of this transmission is continuously changing, thereby realizing automatic adjustment of the transmission ratio. The movement of the compact shelving can become a smoother sliding, optimizing the transmission ratio to improve the power transmission efficiency, reduce energy loss, and improve the smoothness of the operator's operation. It can also adapt to different loads to provide better power output, so that the flexibility and responsiveness of the compact shelving are significantly improved.

[0049] Automatic reversing steps:

[0050] like Figures 5 to 8 As shown, when the compact shelving is in the initial state, the saw gear 1 313 and the saw gear 2 314 are in meshing state, the saw gear 3 315 and the saw gear 4 316 are in separation state, and the spring 326 is in a stretched state between the fixed column 1 325 and the trigger column 2 332;

[0051] When the driven disk 226 rotates counterclockwise, it drives the gear piece 1 31 and the saw gear 3 315 to rotate simultaneously. The saw gear 3 315 is composed of an internal gear and a sliding sleeve that is rotatably connected to the outer wall of the gear. At this time, the gear inside the saw gear 315 is not engaged with the saw gear 4 316. When the saw gear 3 315 rotates counterclockwise, it cannot drive the saw gear 4 316 to rotate simultaneously. The counterclockwise rotation of the gear piece 1 31 drives the gear piece 1 31 that is engaged with the outer surface of the gear piece 1 31 to rotate clockwise. The gear piece 2 311 drives the rotating shaft 2 312 and the saw gear 1 313 to rotate simultaneously in a clockwise direction. The saw gear 1 313 is composed of an internal gear and a sliding sleeve that is rotatably connected to the outer wall of the gear. When the saw gear 1 313 rotates clockwise, it drives the saw gear 2 314 to rotate at the same time, and the saw gear 2 314 drives the pulley 14 to rotate clockwise, thereby moving the compact rack. When the compact rack moves to the top, the protrusion of the trigger rod 331 close to the bottom end of the saw gear 4 316 passes through the inclined surface of the inclined block 1 333, causing the trigger bar 33 to swing in the opposite direction. As the trigger bar 33 swings, the transmission bar 321 and the swing bar 324 are driven to swing at the same time through the spring 326. As the transmission bar 321 swings, the transmission rod 1 322 and the transmission rod 2 323 at both ends move at the same time. At this time, the transmission rod 1 322 drives the tooth piece 2 311 to move away. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. When the gear 315 is in the state of being meshed, the gear 316 is in the state of being meshed with the gear 316. Inserting the two sides of the pull rod 342 into the grooves on the inner side of the fixing clamp 341, the swing bar 324 is stuck in the middle, which will cause the saw gear three 315 and the saw gear four 316 in the meshing state to separate, so that when the staff turns the crank 211 again, the compact shelving will not move. In this way, after the compact shelving moves in one direction to the top, it can move in the same direction again without additional operation. The moving direction of the compact shelving can be automatically changed, making the movement of the compact shelving more convenient, and the effect of rapid reversing can be achieved, so that the efficiency of movement will be significantly improved when the compact shelving needs to be moved frequently, and the compact shelving can be locked to prevent children from moving it without authorization.
