Description

Technical Field

[0001] This invention relates to the field of warehousing equipment technology, and more specifically to a storage rack. Background Technology

[0002] When storing equipment and supplies, various storage racks are usually placed in smart warehouses to store the equipment and supplies. When using the storage racks, multiple storage boards are usually set at equal intervals to make full use of the top space of the warehouse. However, when placing equipment or supplies on storage boards that are high up, staff need to lift the equipment or supplies and place them on the storage boards, which is quite strenuous. If the equipment or supplies are heavy, staff are prone to fatigue after storing a large number of items, making it inconvenient to use. Summary of the Invention

[0003] To overcome the aforementioned technical problems, the present invention aims to provide a storage rack in which a sliding rod is screwed to the side of an adjusting screw. The adjusting screw can be rotated to move the sliding rod to the side of a higher placement plate. A pushing rod is used to move the placement plate toward the connecting frame, gradually moving the placement plate into the connecting frame. After the placement plate is misaligned with the placement plate below it, the adjusting screw can be rotated in the opposite direction, causing the sliding rod to move the placement plate downwards, thereby lowering the placement plate to a lower position, making it easier for staff to store equipment.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A storage rack includes a placement module and a conveying module. The placement module includes a top plate, with support columns fixedly connected to the four corners of the bottom surface of the top plate. A plurality of placement plates are equidistantly arranged on the bottom of the top plate. Abutment rods are fixedly connected to both sides of the top surface of each placement plate. The bottom surface of each placement plate contacts the top of an adjacent abutment rod. A support rod is fixedly connected to one long side of the bottom surface of the top plate. A plurality of support mechanisms are fixedly connected to the sides of the support rods and the four support columns corresponding to the placement plates. The bottom surface of each placement plate contacts five adjacent support mechanisms. The conveying module includes a fixed frame. The inner side of the fixed frame is fixedly connected to the bottom of the sides of the four support columns. An adjusting screw, rotatably connected to the top plate, is rotatably connected to the top surface of the fixed frame on one side of the support rod. A sliding rod, slidably connected to an adjacent support column, is screwed onto the side of the adjusting screw. A connecting frame is rotatably connected to the side of the sliding rod away from the support rod. A stop block, contacting the connecting frame, is fixedly connected to the bottom of the sliding rod side. A connecting box is fixedly connected to one side of the sliding rod on one side of the support rod. A push rod is rotatably connected to the top surface of the connecting box. A support rod is rotatably connected to one end of the push rod.

[0006] Equipment can be stored on the placement plate, which is supported by a support mechanism. When equipment needs to be placed on a higher placement plate, the adjusting screw can be rotated to move the sliding rod to the higher placement plate. At this time, the push rod can be rotated to push the placement plate towards the connecting frame. The placement plate will cause the connecting frame to rotate downwards, and the placement plate will gradually move into the connecting frame. After the placement plate is misaligned with the placement plate below it, the adjusting screw can be rotated in the opposite direction to move the sliding rod and the connecting frame and placement plate downwards, thereby lowering the placement plate to a lower position for easy storage of equipment by staff.

[0007] Furthermore, the top plate has two short sides on its bottom surface that are fixedly connected to the fixing frame. Both ends of the fixing plate are fixedly connected to the bottom side of the adjacent support column. The top surface of the fixing plate is fixedly connected to a side plate that is fixedly connected to the top plate. A connecting screw rod that is rotatably connected to the top plate is rotatably connected to one side of the top surface of the fixing plate. A sliding seat that is screwed to the side of the connecting screw rod is slidably connected to the bottom of the opposite surfaces of the two side plates. A rotating block that contacts the bottom surface of the adjacent placement plate is rotatably connected to the inner side of the sliding seat. A fixed shaft that is rotatably connected to the rotating block is fixedly connected to the inner side of the sliding seat. A torsion spring is provided on the side of the fixed shaft and the inner side of the rotating block. When the placement plate at the higher position is lowered, the connecting screw rod can be rotated, causing the sliding seat to move the top placement plate upward through the rotating block. The placement plate can be moved upward through the abutment rod, so that the bottom placement plate fills the position of the lowered placement plate. In this way, after storing the equipment, the lowered placement plate can be directly moved to the empty space at the bottom, making it easy to quickly move the placement plate between the support columns.

[0008] Furthermore, a pulley is fixedly sleeved on the side of the connecting screw inside the top plate, and the two pulleys are connected by a pulley drive. A power motor is fixedly connected to one side of the top surface of the top plate, and the output end of the power motor is connected to the top of a connecting screw. The power motor can drive one connecting screw to rotate, and the two connecting screws can be kept rotating synchronously through the pulleys. There is no need to manually rotate the connecting screw, which is convenient for use.

[0009] Furthermore, the support mechanism includes a fixed base, with the sides of the support column and support rod fixedly connected to the sides of adjacent fixed bases. A support block is rotatably connected to the side of the fixed base, contacting the bottom surface of the adjacent placement plate. A connecting shaft is fixedly connected to the side of the fixed base and rotatably connected to the support block. A torsion spring is provided between the side of the connecting shaft and the inner side of the support block. The fixed base can prevent the support block from rotating downwards. Thus, the fixed base can support the placement plate through the support block. When the sliding base moves the placement plate upwards via the rotating block, the placement plate can move its top placement plate via the abutment rod. When the top support block contacts the top plate, it will rotate upward, allowing the placement plate to pass through the support block. After the placement plate separates from the support block, under the action of the torsion spring, the support block will rotate downward back to its original position, causing the connecting screw to rotate in the opposite direction. This causes the placement plate to move downward and land on the adjacent support block, while the bottom placement plate moves upward to fill the original position of the lowered placement plate. This also frees up the space corresponding to the lowered placement plate, making it easier to move the lowered placement plate into the support column. This ensures that the distance between the top placement plate and the top plate is greater than the length of the abutment, allowing the placement plate to move upward a sufficient distance to pass through the support block.

[0010] Furthermore, a stop bar is provided on the inner side of the support column. The support column can block the rear of the placement plate, and the stop bar can block the front of the placement plate. When it is necessary to lower the placement plate, the stop bar can be moved to the inner side of the support column to offset the stop bar from the placement plate. A locking screw that contacts the side of the stop bar can be provided on the support column. The stop bar is limited by the locking screw.

[0011] Furthermore, the inner side of the connecting frame is fixedly connected to a rotating shaft that is rotatably connected to the inner side of the sliding rod. A torsion spring is provided between the inner side of the sliding rod and the side of the rotating shaft. Both ends of the top surface of the fixed frame are fixedly connected to limiting rods that are slidably connected to the inner sides of adjacent sliding rods. The top of the limiting rod is fixedly connected to the inner side of the top plate. Under the action of the torsion spring, the angle between the rotating shaft and the connecting frame can be maintained, so that the connecting frame is kept in a retracted state, avoiding the connecting frame from occupying too much space.

[0012] Furthermore, the adjusting screw is fixedly fitted with a second pulley inside the top plate on its side, and the two pulleys are connected by a belt drive. A drive motor is fixedly connected to the top surface of the top plate at the top of one adjusting screw, and the output end of the drive motor is connected to the top of the adjusting screw. The drive motor can drive one adjusting screw to rotate, and one adjusting screw can drive the other adjusting screw to rotate through the second pulley, so that the two adjusting screws rotate synchronously. There is no need to manually rotate the adjusting screw, which is convenient to use.

[0013] Furthermore, the inner side of the connecting box is rotatably connected to a rotating rod, and the inner side of a sliding rod is rotatably connected to a rotating cylinder. The inner side of the rotating cylinder is fixedly connected to two locking blocks. An adjusting screw has a locking groove on its side that is slidably connected to an adjacent locking block. Both the side of the rotating cylinder and the side of the rotating rod are fixedly fitted with pulleys three, and the two pulleys three are connected by belt drive. The side of the rotating rod is fixedly fitted with a connecting gear. The bottom surface of the pushing rod is fixedly connected to a connecting rod that is rotatably connected to the inner side of the connecting box. The side of the connecting rod is fixedly fitted with a missing gear that meshes with the connecting gear. The bottom of the side of the connecting rod is provided with a fixing cylinder that is fixedly connected to the bottom surface of the connecting box. A torsion spring three is provided between the side of the connecting rod and the fixing cylinder.

[0014] The locking block can slide within the locking slot. The adjusting screw can drive the rotating cylinder to rotate through the locking block and the locking slot. When the adjusting screw rotates and moves the sliding rod upward, the connecting gear will not drive the missing gear to rotate, thus preventing the push rod from rotating. This moves the sliding rod to the position where it needs to be lowered. When the adjusting screw rotates in the opposite direction, it will drive the rotating cylinder to rotate through the locking block and the locking slot. The rotating cylinder drives the rotating rod to rotate through the pulley three. Under the action of the torsion spring three, the teeth of the missing gear remain in contact with the connecting gear. This allows the connecting gear to drive the missing gear to rotate, causing the connecting rod to drive the push rod and support rod to rotate. This push rod and support rod then push the placement plate into the connecting frame. After the missing gear drives the push rod to rotate 90 degrees, the gear on the missing gear will disengage from the connecting gear, preventing the missing gear and push rod from continuing to rotate. Since the sliding rod moves a small distance when the adjusting screw drives the missing gear to rotate 90 degrees, the placement plate can be moved smoothly into the connecting frame. Moving the placement plate into the connecting frame and then lowering it is simple and convenient to use.

[0015] The beneficial effects of this invention are:

[0016] 1. By adjusting the screw and connecting the sliding rod to the side, the equipment can be stored on the placement plate. When it is necessary to place the equipment on the placement plate at a higher position, the screw can be rotated to move the sliding rod to the side of the higher placement plate. The push rod can be rotated to move the placement plate towards the connecting frame. The placement plate will cause the connecting frame to rotate downward and gradually move into the connecting frame. After the placement plate is misaligned with the placement plate below it, the screw can be rotated in the opposite direction to move the sliding rod to move the placement plate downward, thereby lowering the placement plate to a lower position, making it easier for staff to store the equipment.

[0017] 2. A rotating block is rotatably connected to the inner side of the sliding seat. After the higher placement plate is lowered, the connecting screw is rotated by the power motor, causing the sliding seat to move the bottom placement plate upward through the rotating block. The placement plate can then move the top placement plate upward through the abutment rod, thus filling the position of the lowered placement plate with the bottom placement plate. After storing the equipment, the lowered placement plate can be directly moved to the empty space at the bottom, facilitating quick movement of the placement plate into the support column. 3. A rotating cylinder is rotatably connected to the inner side of the sliding rod. After the adjusting screw rotates forward to move the sliding rod next to the corresponding placement plate, rotating the adjusting screw in the opposite direction will cause the push rod to rotate through the connecting gear and the missing gear, thereby pushing the placement plate into the connecting frame. There is no need to manually rotate the push rod, making it convenient to use. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-14As shown, a storage rack includes a placement module 100 and a conveying module 200. The placement module 100 includes a top plate 110, with support columns 111 fixedly connected to the four corners of the bottom surface of the top plate 110. A plurality of placement plates 120 are equidistantly arranged at the bottom of the top plate 110. Abutment rods 121 are fixedly connected to both sides of the top surface of each placement plate 120, with the bottom surface of the placement plate 120 contacting the top of the adjacent abutment rods 121. A support rod 160 is fixedly connected to one long side of the bottom surface of the top plate 110. A plurality of support mechanisms 140 are fixedly connected to the sides of the four support columns 111 corresponding to the placement plates 120, with the bottom surface of each placement plate 120 contacting five adjacent support mechanisms 140. The conveying module 200 includes a fixing frame 210. The inner side of the fixed frame 210 is fixedly connected to the bottom of the sides of the four support columns 111. The top surface of the fixed frame 210 is rotatably connected to the adjusting screw 211, which is rotatably connected to the top plate 110, located on the side of the support rod 160. The side of the adjusting screw 211 is screwed to the sliding rod 220, which is slidably connected to the adjacent support column 111. The side of the sliding rod 220 away from the support rod 160 is rotatably connected to the connecting frame 240. The bottom of the side of the sliding rod 220 is fixedly connected to the stop block 221, which contacts the connecting frame 240. The side of one sliding rod 220 is fixedly connected to the connecting box 250, located on the side of the support rod 160. The top surface of the connecting box 250 is rotatably connected to the push rod 260. One end of the push rod 260 is rotatably connected to the support rod 261.

[0035] Equipment can be stored on the placement plate 120. The support mechanism 140 can support the placement plate 120. When it is necessary to place the equipment on the placement plate 120 at a higher position, the adjusting screw 211 can be rotated to move the sliding rod 220 to the higher placement plate 120. At this time, the pushing rod 260 can be rotated to push the placement plate 120 towards the connecting frame 240. The placement plate 120 will cause the connecting frame 240 to rotate downward. At the same time, the placement plate 120 will gradually move into the connecting frame 240. After the placement plate 120 is misaligned with the placement plate 120 at its bottom, the adjusting screw 211 can be rotated in the opposite direction to move the sliding rod 220 to drive the connecting frame 240 and the placement plate 120 downward, thereby lowering the placement plate 120 to a lower position, making it easier for staff to store equipment.

[0036] The top plate 110 has two short sides on its bottom surface with fixed plates 130 that are fixedly connected to the fixing frame 210. Both ends of the fixed plates 130 are fixedly connected to the bottom sides of adjacent support columns 111. The top surface of the fixed plates 130 is fixedly connected to side plates 131 that are also fixedly connected to the top plate 110. A connecting screw 132, rotatably connected to the top plate 110, is rotatably connected to one side of the top surface of the fixed plates 130. The bottom surfaces of the two side plates 131 are slidably connected to sliding seats 133 that are screwed onto the sides of the connecting screw 132. A rotating block 134, in contact with the bottom surface of the adjacent placement plate 120, is rotatably connected to the inner side of the sliding seat 133. A rotating block 134, in contact with the bottom surface of the adjacent placement plate 120, is fixedly connected to the inner side of the sliding seat 133. The fixed shaft 135 is rotatably connected to the fixed shaft 135. A torsion spring 136 is provided on the side of the fixed shaft 135 and the inner side of the rotating block 134. After the placement plate 120 at the higher position is lowered, the connecting screw 132 can be rotated, so that the sliding seat 133 drives the placement plate 120 at its top to move upward through the rotating block 134. The placement plate 120 can be moved upward through the abutment 121, so that the bottom placement plate 120 fills the position of the placement plate 120 that will be lowered. In this way, after storing the equipment, the lowered placement plate 120 can be moved directly to the empty space at the bottom, which is convenient for quickly moving the placement plate 120 between the support columns 111.

[0037] Under the action of the torsion spring 136, the rotating block 134 can maintain a constant angle and can rotate upward to offset the placement plate 120. In this way, the sliding seat 133 and the rotating block 134 can be moved to the bottom of the placement plate 120 at the corresponding height by the connecting screw 132. Then, the rotating block 134 can be released, so that the bottom placement plate 120 can be lowered to the position of the sliding seat 133 as needed. Then, by rotating the connecting screw 132, the sliding seat 133 drives the placement plate 120 on top of it to move upward through the rotating block 134, so that the empty space is at the corresponding height. Then, the lowered placement plate 120 can be moved into the empty space. In this way, the placement plate 120 can be lowered to the corresponding height according to the needs of placing the equipment. The placement plate 120 can be lowered directly to the bottom, which is convenient for placing heavy equipment. The placement plate 120 can also be given a certain height so that the staff does not need to bend over to place the equipment. A positioning screw that contacts the fixed shaft 135 can be set on the rotating block 134 to maintain the angle of the rotating block 134 after it is rotated upward.

[0038] A pulley is fixedly sleeved on the side of the connecting screw 132 inside the top plate 110, and the two pulleys are connected by a pulley drive. A power motor 150 is fixedly connected to one side of the top surface of the top plate 110. The output end of the power motor 150 is connected to the top of one connecting screw 132. The power motor 150 can drive one connecting screw 132 to rotate. The two connecting screws 132 can be kept rotating synchronously through the pulleys. There is no need to manually rotate the connecting screw 132, which is convenient to use.

[0039] The support mechanism 140 includes a fixed base 141. The sides of the support column 111 and the support rod 160 are fixedly connected to the sides of the adjacent fixed base 141. A support block 142, which contacts the bottom surface of the adjacent placement plate 120, is rotatably connected to the side of the fixed base 141. A connecting shaft 143, which is rotatably connected to the support block 142, is fixedly connected to the side of the fixed base 141. A torsion spring 144 is provided between the side of the connecting shaft 143 and the inner side of the support block 142. The fixed base 141 can prevent the support block 142 from rotating downwards. Thus, the fixed base 141 can support the placement plate 120 through the support block 142. When the sliding base 133 drives the placement plate 120 upwards via the rotating block 134, the placement plate 120 can move its top plate via the abutment rod 121. After the top support block 142 contacts, it will rotate upward, allowing the placement plate 120 to pass through it. After the placement plate 120 separates from the support block 142, the support block 142 will rotate downward to its original position under the action of the torsion spring 136. This will cause the connecting screw 132 to rotate in the opposite direction, allowing the placement plate 120 to move downward and land on the adjacent support block 142. This will cause the bottom placement plate 120 to move upward and fill the original position of the lowered placement plate 120, and free up space for the corresponding lowered placement plate 120. This will facilitate the movement of the lowered placement plate 120 into the support column 111. The distance between the top placement plate 120 and the top plate 110 will be greater than the length of the abutment rod 121, allowing the placement plate 120 to move upward a sufficient distance to pass through the support block 142.

[0040] A stop bar 112 is provided on the inner side of the support column 111. The support rod 160 can block the rear of the placement plate 120, and the stop bar 112 can block the front of the placement plate 120. When it is necessary to lower the placement plate 120, the stop bar 112 can be moved to the inner side of the support column 111 to offset the stop bar 112 from the placement plate 120. A locking screw that contacts the side of the stop bar 112 can be provided on the support column 111. The stop bar 112 is limited by the locking screw.

[0041] A rotating shaft 241, which is rotatably connected to the inner side of the sliding rod 220, is fixedly connected to the inner side of the connecting frame 240. A torsion spring 4 is provided between the inner side of the sliding rod 220 and the side of the rotating shaft 241. Both ends of the top surface of the fixing frame 210 are fixedly connected to limiting rods 212, which are slidably connected to the inner side of the adjacent sliding rod 220. The top of the limiting rod 212 is fixedly connected to the inner side of the top plate 110. Under the action of the torsion spring 4, the angle between the rotating shaft 241 and the connecting frame 240 can be maintained, so that the connecting frame 240 is kept in a retracted state, thus avoiding the connecting frame 240 occupying too much space.

[0042] The adjusting screw 211 is fixedly sleeved with a pulley 2 inside the top plate 110 on its side, and the two pulleys 2 are connected by belt drive. The top of one adjusting screw 211 is equipped with a drive motor 230 fixedly connected to the top surface of the top plate 110, and the output end of the drive motor 230 is connected to the top of the adjusting screw 211. The drive motor 230 can drive one adjusting screw 211 to rotate, and one adjusting screw 211 can drive the other adjusting screw 211 to rotate through the pulley 2, so that the two adjusting screws 211 rotate synchronously. There is no need to manually rotate the adjusting screw 211, which is convenient to use.

[0043] A rotating rod 251 is rotatably connected to the inner side of the connecting box 250. A rotating cylinder 222 is rotatably connected to the inner side of a sliding rod 220. Two locking blocks are fixedly connected to the inner side of the rotating cylinder 222. A locking groove for sliding connection with adjacent locking blocks is opened on the side of an adjusting screw 211. Belt pulleys are fixedly sleeved on the side of the rotating cylinder 222 and the side of the rotating rod 251, and the two belt pulleys are connected by belt drive. A connecting gear 252 is fixedly sleeved on the side of the rotating rod 251. A connecting rod 262 is rotatably connected to the inner side of the connecting box 250 and fixedly sleeved on the side of the connecting rod 262. A missing gear 263 that meshes with the connecting gear 252 is fixedly sleeved on the side of the connecting rod 262. A fixed cylinder 264 is fixedly connected to the inner bottom surface of the connecting box 250 and provided at the bottom of the side of the connecting rod 262. A torsion spring 265 is provided between the side of the connecting rod 262 and the fixed cylinder 264.

[0044] The locking block can slide within the locking groove. The adjusting screw 211 can drive the rotating cylinder 222 to rotate via the locking block and locking groove. When the adjusting screw 211 rotates, causing the sliding rod 220 to move upwards, the connecting gear 252 will not drive the missing gear 263 to rotate, thus preventing the push rod 260 from rotating. Instead, the sliding rod 220 is moved to the position where it needs to be lowered. When the adjusting screw 211 rotates in the opposite direction, it will drive the rotating cylinder 222 to rotate via the locking block and locking groove. The rotating cylinder 222 drives the rotating rod 251 to rotate via the pulley 3. Under the action of the torsion spring 3 265, the teeth of the missing gear 263 remain in contact with the connecting gear 252, thus allowing the connecting gear 252 to... The missing gear 263 is driven to rotate, causing the connecting rod 262 to drive the push rod 260 and the support rod 261 to rotate. This push rod 260 and the support rod 261 push the placement plate 120 into the connecting frame 240. After the missing gear 263 drives the push rod 260 to rotate 90 degrees, the gear on the missing gear 263 will disengage from the connecting gear 252, so that the missing gear 263 and the push rod 260 will not continue to rotate. Since the sliding rod 220 moves a small distance when the adjusting screw 211 drives the missing gear 263 to rotate 90 degrees, the placement plate 120 can be moved smoothly into the connecting frame 240. Moving the placement plate 120 into the connecting frame 240 and then lowering the placement plate 120 is simple and easy to use.

[0045] Working principle: When in use, the equipment can be placed on the placement plate 120. When it is necessary to place the equipment on the placement plate 120 at a higher height, the drive motor 230 can be started. The drive motor 230 can drive an adjusting screw 211 to rotate. One adjusting screw 211 can drive another adjusting screw 211 to rotate through the pulley 2. The rotation of the adjusting screw 211 can move the sliding rod 220 upward, which in turn drives the connecting frame 240, the connecting box 250 and the push rod 260 to move upward.

[0046] After moving the sliding rod 220 to the corresponding placement plate 120 and aligning the push rod 260 with the placement plate 120, the adjusting screw 211 can be rotated in the opposite direction by the drive motor 230. The adjusting screw 211 can drive the rotating cylinder 222 to rotate through the locking slot and locking block. The rotating cylinder 222 can drive the rotating rod 251 to rotate through the pulley 3. Under the action of the torsion spring 3 265, the teeth of the missing gear 263 are kept in contact with the connecting gear 252. In this way, the connecting gear 252 can drive the missing gear 263 to rotate, the missing gear 263 can drive the connecting rod 262 to rotate, and the connecting rod 262 can drive the push rod 260 and the support rod 261 to rotate. The push rod 260 and the support rod 261 can move the placement plate 120, causing the placement plate 120 to move towards the connecting frame 240. The top side of the placement plate 120 will first contact the connecting frame 240, making... The connecting frame 240 rotates downward and contacts the stop block 221. Then the placement plate 120 will gradually move into the connecting frame 240. The stop block 221 can support the connecting frame 240 and the placement plate 120. After the missing gear 263 drives the push rod 260 to rotate 90 degrees, the gear on the missing gear 263 will disengage from the connecting gear 252, so that the push rod 260 will not continue to rotate. At this time, the push rod 260 and the support rod 261 will cause the placement plate 120 to be misaligned with the placement plate 120 at its bottom. In this way, the adjusting screw 211 will continue to rotate in the opposite direction, which will cause the sliding rod 220 to continue to move downward and drive the placement plate 120 to move downward, thereby lowering the placement plate 120 so that the placement plate 120 corresponds to the placement plate 120 at the top of the sliding seat 133. When the placement plate 120 moves downward, the push rod 260 and the support rod 261 will pass through the opening of the placement plate 120.

[0047] The equipment can be placed on the lowered placement plate 120, and the power motor 150 can be started simultaneously. The power motor 150 can drive one connecting screw 132 to rotate. One connecting screw 132 can drive another connecting screw 132 to rotate via a pulley. The rotation of the connecting screw 132 can move the sliding seat 133 upward, causing the sliding seat 133 to drive the rotating block 134 upward. The rotating block 134 will drive the placement plate 120 on top of it to move upward. The placement plate 120 can be moved by the abutment rod 121. After the placement plate 120 contacts the support block 142 on top, The placement plate 120 will cause the support block 142 to rotate upward, so that the placement plate 120 will pass through the support block 142. Then, under the action of the torsion spring 136, the support block 142 will rotate downward to its original position. Then, the connecting screw 132 can be rotated in the opposite direction by the power motor 150, so that the sliding seat 133 drives the rotating block 134 to move downward, so that the placement plate 120 falls on the adjacent support block 142, and the bottom placement plate 120 moves upward to fill the original position of the lowered placement plate 120. Then, the sliding seat 133 and the rotating block 134 can continue to move downward to their original positions.

[0048] After placing the equipment on the lowered placement plate 120 and the sliding seat 133 moves to its original position, the placement plate 120 can be pushed onto the support mechanism 140 at the same height as the sliding seat 133. Even if the lowered placement plate 120 fills the bottom space, after the placement plate 120 separates from the connecting frame 240, under the action of the torsion spring four, the rotating shaft 241 can drive the connecting frame 240 to rotate upward to its original angle. Then, the adjusting screw 211 can be rotated forward again by the drive motor 230. Under the action of the torsion spring three 265, the teeth of the missing gear 263 keep in contact with the connecting gear 252. In this way, the connecting gear 252 can drive the missing gear 263 to rotate forward, so that the connecting rod 262 can drive the push rod 260 and the support rod 261 to rotate to their original positions. Then, the adjusting screw 211 can continue to rotate, so that the sliding rod 220 can move upward to its original position.
