Description

Technical Field

[0001] This application relates to the technical field of warehousing logistics, and in particular to a hoist for multi-directional incoming and outgoing goods. Background Art

[0002] The three-dimensional shelf realizes the multi-layer storage of goods, improving the space utilization rate of the warehouse in warehousing logistics. When storing goods on the three-dimensional shelf, a hoist is required to realize the transfer of goods between different layers.

[0003] The existing hoist docks with the logistics conveying equipment or goods storage cavities on different layers of the three-dimensional shelf through the two opposite sides of the liftable platform. The logistics conveying equipment or goods storage cavity conveys the goods onto the liftable platform, and the liftable platform drives the goods to lift and conveys the goods to be placed on the logistics conveying equipment or goods storage cavity on another layer of the three-dimensional shelf, enabling the goods to be transferred between different layers or directly stored.

[0004] The hoist transfers goods between its two opposite sides, reducing the docking effect between the hoist and the three-dimensional shelf and being unfavorable for giving full play to the storage advantages of the three-dimensional shelf. Summary of the Invention

[0005] In order to improve the docking effect between the hoist and the three-dimensional shelf, this application provides a hoist for multi-directional incoming and outgoing goods.

[0006] A hoist for multi-directional incoming and outgoing goods provided by this application adopts the following technical solutions:

[0007] A hoist for multi-directional incoming and outgoing goods includes:

[0008] A frame, which is provided with an even number of incoming and outgoing ports along the circumferential direction, and the number of the incoming and outgoing ports is at least four, and all the incoming and outgoing ports are opened in pairs opposite to each other;

[0009] A lifting platform, which is slidably arranged in the frame;

[0010] At least four sets of outgoing components, all of which are located on the lifting platform. The outgoing components correspond to the incoming and outgoing ports one by one, and each includes a push rod, a goods pushing part and a swinging part;

[0011] Wherein, one end of the push rod is slidably arranged in a goods pushing chute opened on the lifting platform, and the sliding direction is the same as the incoming and outgoing direction of the incoming and outgoing port;

[0012] The goods pushing part is arranged on the lifting platform and is used for driving the push rod to slide relative to the lifting platform;

[0013] The swinging part is connected between the push rod and the goods pushing part. The swinging part is used to make the push rod and the goods pushing part in a swinging state when the push rod is located at the end of the goods pushing chute, and is used to make the push rod and the goods pushing part in a fixed state when the push rod slides in the goods pushing chute.

[0014] By adopting the above technical solution, more than four loading and unloading ports on the rack increase the docking interfaces between the elevator and the stereoscopic shelf, enhance the docking performance between the elevator and the stereoscopic shelf. The logistics conveying equipment or the goods storage cavity can convey goods from any one of the loading and unloading ports to the lifting platform. The swinging part enables the push rod to swing relative to the goods pushing part when the push rod is at the end of the goods pushing chute, so that the goods can enter the lifting platform by pushing the push rod to swing. When unloading is required, the goods pushing part can push the push rod to slide along the goods pushing chute, and under the action of the swinging part, the push rod and the goods pushing part are in a fixed state, and the push rod can push the goods out of the lifting platform, so that the goods can be conveyed from any one of the loading and unloading ports to the logistics conveying equipment or the goods storage cavity, thereby enabling the elevator to load and unload goods through multiple interfaces arbitrarily, and further improving the docking effect between the elevator and the stereoscopic shelf.

[0015] Optionally, the discharging assemblies corresponding to each pair of opposite loading and unloading ports are located in the same goods pushing chute. The goods pushing part includes a slider, the slider is slidably arranged in a driving chute opened on the side wall of the goods pushing chute, and is connected to the push rod through the swinging part. First electromagnets are fixedly arranged on the side walls of the slider and the driving chute end close to each other, and a second electromagnet is fixedly arranged at one end of the slider away from the first electromagnet.

[0016] By adopting the above technical solution, the two first electromagnets at the end of the slider and the driving chute can drive the slider to reciprocate through magnetic thrust and magnetic attraction. At the same time, the second electromagnet between the two sliders can assist the slider to reciprocate through magnetic thrust and magnetic attraction, so that the slider can easily drive the push rod to move along the driving chute, enabling the push rod to push the goods out of the lifting platform, and thus enabling the goods to be easily moved out of the lifting platform from any one of the loading and unloading ports.

[0017] Optionally, the swinging part includes a swinging disk and a return spring. The swinging disk is arranged through the part of the slider opposite to the goods pushing chute and is rotatably connected to the slider. The push rod is fixedly arranged through the swinging disk. The return spring is arranged between the push rod and the slider and is used to drive the push rod to reset after swinging.

[0018] By adopting the above technical solution, the push rod can swing relative to the slider through the swinging disk, and under the elastic force of the return spring, the push rod can automatically reset after swinging, making it easy for the goods to push the push rod to swing and making it difficult for the push rod to affect the movement of the goods into or out of the lifting platform under the condition of being able to push the goods.

[0019] Optionally, the swinging part further includes a fixing rod, which is fixedly arranged at one end of the push rod located in the goods-pushing chute. A fixing chute for the end of the fixing rod to slide is formed on the side wall of the goods-pushing chute, and a swinging chute for the fixing rod to swing is formed at the end.

[0020] By adopting the above technical solution, when the push rod is located at the end of the goods-pushing chute, the fixing rod can swing with the push rod in the swinging chute, so that the fixing rod is not likely to affect the swinging of the push rod; when the push rod drives the fixing rod to slide into the fixing chute, under the limiting action of the fixing chute, it is difficult for the push rod to swing, so that the push rod can be relatively fixed to the slider when pushing the goods.

[0021] Optionally, a plurality of bull's-eye wheels are fixedly arranged on the lifting platform.

[0022] By adopting the above technical solution, after the goods move to the lifting platform, they can be located on the bull's-eye wheels, reducing the friction between the goods and the lifting platform and making it easy for the goods to be moved into or out of the lifting platform.

[0023] Optionally, two transition rollers are symmetrically and rotatably connected to one end of the push rod located outside the goods-pushing chute, and the axial directions of the two transition rollers are perpendicular to the sliding direction of the push rod.

[0024] By adopting the above technical solution, on the one hand, the two transition rollers on the push rod can cooperate with the push rod to stably push the goods to move. On the other hand, when the goods are moved into or out of the lifting platform, the transition rollers swing with the push rod, and the rotatable transition rollers can make the goods move onto the bull's-eye wheels in a rolling manner, so that the goods are easy to move onto the bull's-eye wheels, and during the movement process, the transition rollers can play a continuous role.

[0025] Optionally, a control component is arranged between each pair of corresponding two sets of the goods-out components corresponding to the inlet / outlet openings, and the control component is used to control the swinging direction of the push rod at the end of the goods-pushing chute in the two sets of the goods-out components;

[0026] When the push rods of the two sets of the goods-out components are both located at the ends of the goods-pushing chutes, the control component controls the swinging directions of the two push rods to only face the inner side of the lifting platform;

[0027] When the push rod of one set of the goods-out components slides and the push rod of the other set of the goods-out components is located at the end of the goods-pushing chute, the control component controls the swinging direction of the push rod located at the end of the goods-pushing chute to be in a free state during the initial sliding stage of the sliding push rod.

[0028] By adopting the above technical solution, the control component can control the swinging direction of the push rod at the end of the goods pushing chute; when there is no need to push the goods, the control component controls the push rod to swing only towards the inner side of the lifting platform, so that the goods can be easily moved into the lifting platform and it is difficult for the goods to move out of the lifting platform, making it difficult for the goods to slip when following the lifting platform up and down; when it is necessary to push the goods out of the lifting platform, the push rod in the direction of the goods moving out can swing freely under the control of the control component, so that the goods are not easily blocked by the push rod in the direction of its own movement when moving out of the lifting platform.

[0029] Optionally, the control component includes two control units. One set of the goods discharging components controls the swinging direction of the push rod in the other set of the goods discharging components through one of the control units, and the other set of the goods discharging components controls the swinging direction of the push rod in one set of the goods discharging components through the other control unit.

[0030] In one of the control units, the control unit includes a driving oil cylinder, a control oil cylinder, a limiting block and a control block.

[0031] The driving oil cylinder is embedded in the side wall of the driving chute and is located at one end of the driving chute close to the slider in one set of the goods discharging components. The two ends of the side of the slider close to the driving oil cylinder are inclined in the direction away from each other, and the movable end of the driving oil cylinder abuts against the inclined surface at one end of the slider close to the center of the lifting platform.

[0032] The control oil cylinder is embedded in the slider in the other set of the goods discharging components and is located on the side of the swinging disc close to the center of the lifting platform.

[0033] The limiting block is fixedly arranged on the movable end of the control oil cylinder and is slidably arranged in the control chute opened on the slider. The side of the limiting block close to the swinging disc is arc-shaped and fits with the side wall of the swinging disc.

[0034] The control block is fixedly arranged on the side of the swinging disc close to the fixed rod and abuts against one end of the limiting block close to the fixed rod.

[0035] Hydraulic oil flows between the rodless chamber of the driving oil cylinder and the rod chamber of the control oil cylinder through a control oil pipe.

[0036] By adopting the above technical solution, the two control units respectively realize the control of the swinging direction of the push rods in the two sets of goods discharging components. When one of the push rods pushes the goods out of the lifting platform, the swinging direction of the other push rod in the direction of the goods moving out can swing freely.

[0037] When one of the sliders drives the push rod to push the goods, the slider squeezes the movable end of the driving oil cylinder through its inclined surface to contract, so that the hydraulic oil in the rodless cavity of the driving oil cylinder flows into the rod cavity of the control oil cylinder through the control oil pipe. The hydraulic oil pushes the movable end of the control oil cylinder to contract, and the control oil cylinder drives the limit block to slide away from the swing plate, and provides a sliding space for the control block on the swing plate, so that the control block can slide into the control chute, so that the push rod can swing away from the center of the lifting platform.

[0038] Optionally, a control spring for driving the limit block to reset is arranged in the rodless cavity of the control oil cylinder.

[0039] By adopting the above technical solution, when the slider resets, the control spring can drive the control oil cylinder to extend through its own elastic force, and the control oil cylinder drives the limit block to fit with the swing plate again, so that the limit block forms a limit on the control block again.

[0040] Optionally, a lifting assembly is arranged between the lifting platform and the rack. The lifting assembly includes lead screws, lifting gears, driving gears and a lifting motor. There are at least two lead screws, and they are all threadedly arranged at the edge position of the lifting platform. The lead screws are rotatably connected to the rack. There are at least two lifting gears, and they correspond to the lead screws one by one. The lifting gears are coaxially fixed at the ends of the lead screws. The driving gear meshes with all the lifting gears and is rotatably connected to the rack. The lifting motor is fixed to the rack, and the output shaft of the lifting motor is coaxially fixed to the driving gear.

[0041] By adopting the above technical solution, the lifting motor drives the driving gear to rotate, the driving gear drives all the lifting gears to rotate, the lifting gears drive the lead screws to rotate, and the lead screws drive the lifting platform to lift. Thus, by means of the lead screw drive, it is convenient for the goods to be moved into or out of the lifting platform from any one of the loading and unloading ports.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] By providing more than four loading and unloading ports and arranging the push rod, slider, swing plate and fixed rod, the goods can be moved into or out of the lifting platform from any one of the loading and unloading ports, thereby improving the docking effect between the elevator and the stereoscopic shelf;

[0044] By providing bull's-eye wheels and transition rollers, it is easy for the goods to slide into or out of the lifting platform;

[0045] By providing the driving oil cylinder, control oil cylinder, limit block and control block, the swinging direction of the push rod in the direction of goods removal is convenient for automatic regulation. Description of the Drawings

Detailed implementation manners

[0053] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0054] An embodiment of the present application discloses a hoist for multi-directional loading and unloading of goods. Referring to Figure 1 , a hoist for multi-directional loading and unloading of goods includes a frame 1, a lifting platform 2, and a shipping component 3. The frame 1 is provided with four loading and unloading openings 11 along the circumferential direction. The lifting platform 2 is slidably arranged inside the frame 1. There are four groups of shipping components 3, and all are arranged on the lifting platform 2. The shipping components 3 correspond to the loading and unloading openings 11 one by one. The shipping component 3 is used to move goods into or out of the lifting platform 2 from any one of the loading and unloading openings 11.

[0055] During use, all four loading and unloading openings 11 on the rack 1 are docked with the three-dimensional rack to enhance the docking between the elevator and the three-dimensional rack. Goods are conveyed from one of the loading and unloading openings 11 to the lifting platform 2 through the logistics conveying equipment or the goods storage cavity. The lifting platform 2 drives the movement of the goods, and the discharging assembly 3 drives the goods to move from one of the loading and unloading openings 11 to other logistics conveying equipment or the goods storage cavity, enabling the lifting platform 2 to access goods arbitrarily through multiple interfaces, thereby improving the docking effect between the elevator and the three-dimensional rack.

[0056] Refer to Figure 1 , the rack 1 is in the shape of a rectangular frame and is vertically arranged. The four loading and unloading openings 11 are respectively located on the four sides of the rack 1 and are all rectangular, and the four loading and unloading openings 11 are arranged in pairs facing each other.

[0057] The lifting platform 2 is in the shape of a rectangular plate and is horizontally arranged. The sliding direction of the lifting platform 2 and the rack 1 is the vertical direction, and the side is parallel to the side of the rack 1. A lifting assembly 5 is arranged between the lifting platform 2 and the rack 1. The lifting assembly 5 includes a lead screw 51, a lifting gear 52, a driving gear 53, and a lifting motor 54.

[0058] There are four lead screws 51, and they are all vertically arranged. The four lead screws 51 are respectively located at the four top corners of the lifting platform 2 and are all threadedly penetrated through the lifting platform 2. Both ends of the lead screw 51 in the axial direction are rotatably connected to the rack 1.

[0059] The top end of the lead screw 51 penetrates through the top end of the rack 1. There are four lifting gears 52, and they correspond to the lead screws 51 one by one. The lifting gears 52 are coaxially fixed at the top end of the lead screw 51. The driving gear 53 is located between the four lifting gears 52 and meshes with all four lifting gears 52. The lifting motor 54 is located above the driving gear 53 and is fixedly connected to the rack 1. The output shaft of the lifting motor 54 is coaxially fixed to the driving gear 53.

[0060] During use, start the lifting motor 54. The lifting motor 54 drives the driving gear 53 to rotate. The driving gear 53 drives all the lifting gears 52 to rotate. The lifting gears 52 drive the lead screw 51 to rotate. The lead screw 51 drives the lifting platform 2 to move, making it convenient for the lifting platform 2 to move up and down.

[0061] Refer to Figure 1 and Figure 2 , the discharging assembly 3 includes a push rod 31, a goods pushing part 32, and a swinging part 33. The push rod 31 is in the shape of a rectangular rod, and one end in the length direction is slidably arranged in the goods pushing chute 21 opened on the top surface of the lifting platform 2. The goods pushing chute 21 is rectangular and is located in the middle of the lifting platform 2. The sliding direction of the push rod 31 is consistent with the loading and unloading direction of the corresponding loading and unloading opening 11.

[0062] The discharging component 3 corresponding to each pair of opposite loading and unloading ports 11 is located within the same pushing chute 21. The pushing part 32 includes a slider 321, which is in the shape of a rectangular block and is slidably arranged within a driving chute 22 jointly formed on two side walls in the length direction of the pushing chute 21. The driving chute 22 is rectangular, and the sliding direction of the slider 321 is the same as the sliding direction of the push rod 31.

[0063] Referring to Figure 3 , first electromagnets 322 are fixedly arranged on the side walls of the slider 321 and the driving chute 22 close to each other at the end, and a second electromagnet 323 is fixedly arranged at one end of the slider 321 away from the first electromagnet 322. Both the first electromagnet 322 and the second electromagnet 323 are in the shape of rectangular blocks. When the push rod 31 pushes the goods, the polarities of the sides of the two first electromagnets 322 close to each other between the slider 321 and the end of the driving chute 22 are the same, and the polarities of the sides of the two second electromagnets 323 close to each other between the two sliders 321 are opposite. When the push rod 31 completes the pushing of the goods and returns, the polarities of the sides of the two first electromagnets 322 close to each other between the slider 321 and the end of the driving chute 22 are opposite, and the polarities of the sides of the two second electromagnets 323 close to each other between the two sliders 321 are the same.

[0064] The swinging part 33 includes a swinging disc 331, a return spring 332, and a fixing rod 333. The swinging disc 331 is in the shape of a circular plate and is vertically penetrated through the slider 321. The swinging disc 331 is rotatably connected to the slider 321, and the rotation axis is perpendicular to the sliding direction of the slider 321. The push rod 31 is fixedly penetrated through the swinging disc 331, and its length direction is the same as the diameter direction of the swinging disc 331; the return spring 332 is located below the slider 321. One end of the return spring 332 is fixedly connected to the slider 321, and the other end is fixedly connected to the push rod 31. The return spring 332 is used to drive the push rod 31 to return to the vertical state after swinging.

[0065] The fixing rod 333 is in the shape of a circular rod, and its middle part is fixed to one end of the push rod 31 within the pushing chute 21. The axis direction of the fixing rod 333 is perpendicular to the sliding direction of the push rod 31. Fixing chutes 23 for the ends of the fixing rod 333 to slide are jointly formed on two side walls in the length direction of the pushing chute 21. The fixing chutes 23 are rectangular, and a swinging groove 24 for the fixing rod 333 to swing is formed at the end of the pushing chute 21. The swinging groove 24 is rectangular.

[0066] When the fixing rod 333 slides along with the push rod 31, the fixing rod 333 slides within the fixing chute 23 to fix the push rod 31 relative to the slider 321; when the fixing rod 333 swings along with the push rod 31, the swinging groove 24 leaves a swinging space for the fixing rod 333 to swing freely.

[0067] Referring to Figure 1, a plurality of bull's eye wheels 25 are fixedly arranged on the top surface of the lifting table 2, and the plurality of bull's eye wheels 25 are arranged in a matrix. At one end of the push rod 31 located outside the goods pushing chute 21, two transition rollers 311 are symmetrically connected. Both of the two transition rollers 311 are rotatably connected to the push rod 31, and the axial direction of the transition roller 311 is perpendicular to the sliding direction of the push rod 31.

[0068] During use, the slider 321 is fixed to the lifting table 2 under the magnetic attraction of the two first electromagnets 322. Goods are conveyed from the logistics conveying equipment or the goods storage cavity to the lifting table 2, and the push rod 31 is pushed to swing towards the direction close to the center of the lifting table 2. The transition roller 311 on the push rod 31 receives the goods and makes the goods slide onto the bull's eye wheel 25. After the goods slide over the transition roller 311, the return spring 332 drives the push rod 31 to reset to a vertical state, completing the process of moving the goods into the lifting table 2, so that the goods can be loaded from any one of the loading and unloading ports 11.

[0069] Refer to Figure 1 and Figure 3 , between the two sets of discharging components 3 corresponding to each pair of opposite loading and unloading ports 11, a control component 4 is arranged. The control component 4 includes two control units 41. One set of discharging components 3 controls the swinging direction of the push rod 31 in the other set of discharging components 3 through one control unit 41, and the other set of discharging components 3 controls the swinging direction of the push rod 31 in one set of discharging components 3 through the other control unit 41.

[0070] Refer to Figure 3 and Figure 4 , in one of the control units 41, the control unit 41 includes a driving oil cylinder 411, a control oil cylinder 412, a limiting block 413 and a control block 414. The driving oil cylinder 411 is located below the slider 321 in one set of discharging components 3 and is embedded in the side wall of the driving chute 22. The movable end of the driving oil cylinder 411 faces the slider 321. The driving oil cylinder 411 is located at one end of the driving chute 22 close to the slider 321 in one set of discharging components 3. The two ends of the slider 321 on the side close to the driving oil cylinder 411 are inclined in the direction away from each other. The movable end of the driving oil cylinder 411 is rotatably connected with a roller 4111, and the roller 4111 abuts against the inclined surface at one end of the slider 321 close to the center of the lifting table 2. Among them, the driving oil cylinders 411 of the two control units 41 are respectively located on both sides of the length direction of the driving chute 22.

[0071] Refer to Figure 4, the control oil cylinder 412 is embedded in the slider 321 of another set of shipping components 3 and is located on the side of the swing plate 331 close to the center of the lifting table 2. The movable end of the control oil cylinder 412 faces the swing plate 331. The limit block 413 is in the shape of a rectangular block and is fixed on the movable end of the control oil cylinder 412. The limit block 413 is slidably arranged in the control chute 3211 opened on the slider 321. The control chute 3211 is rectangular. The side of the limit block 413 close to the swing plate 331 is arc-shaped and is attached to the side wall of the swing plate 331.

[0072] The control block 414 is in the shape of a rectangular block and is fixed on the side of the swing plate 331 close to the fixed rod 333. The control block 414 abuts against one end of the limit block 413 close to the fixed rod 333.

[0073] Refer to Figure 3 、 Figure 4 and Figure 5 , a control oil pipe 416 is connected between the rodless cavity of the driving oil cylinder 411 and the rod cavity of the control oil cylinder 412, and hydraulic oil flows through the control oil pipe 416. The control oil pipe 416 is located below the fixed rod 333 so that the sliding of the fixed rod 333 does not interfere with the control oil pipe 416.

[0074] Refer to Figure 4 , a control spring 415 is arranged in the rodless cavity of the control oil cylinder 412. One end of the control spring 415 is fixedly connected to the control oil cylinder 412, and the other end is fixedly connected to the movable end of the control oil cylinder 412. The control spring 415 is used to drive the limit block 413 to reset and fit on the swing plate 331.

[0075] During use, the limiting block 413 provides a clamping force to the control block 414, enabling the swing plate 331 to only swing towards the center of the lifting platform 2. Under the clamping action between the control block 414 and the limiting block 413, the push rod 31 and the transition roller 311 form a protection for the goods, making it difficult for the goods to slide during the lifting and lowering process of the lifting platform 2; when it is necessary to remove the goods from the lifting platform 2, the two first electromagnets 322 drive the slider 321 to slide through magnetic thrust, and the two second electromagnets 323 assist the slider 321 to slide through magnetic suction. The slider 321 drives the push rod 31 and the fixed rod 333 to slide through the swing plate 331, causing the fixed rod 333 to slide into the fixed chute 23. The fixed chute 23 fixes the push rod 31 and the slider 321 through the fixed rod 333. The push rod 31 and the transition roller 311 push the goods to move. The sliding slider 321 squeezes the driving oil cylinder 411 to contract through the inclined surface. The driving oil cylinder 411 squeezes the hydraulic oil into the rod chamber of the control oil cylinder 412 through the control oil pipe 416. The hydraulic oil pushes the control oil cylinder 412 to contract. The control oil cylinder 412 drives the limiting block 413 to slide, and leaves a space for the control block 414 to slide, enabling the push rod 31 in the direction of the goods being removed to swing away from the center of the lifting platform 2. The goods push the push rod 31 in the direction of their own removal to swing under the thrust, and move out of the lifting platform 2, so that the goods can be removed from any one of the loading and unloading ports 11, thereby improving the docking effect between the elevator and the stereoscopic shelf.

[0076] The implementation principle of the elevator for multi-directional loading and unloading of goods in the embodiment of the present application is as follows: During use, the logistics conveying equipment or the goods storage chamber conveys the goods from one of the loading and unloading ports 11 to the lifting platform 2. The goods push the push rod 31 to swing towards the center of the lifting platform 2. The transition roller 311 receives the goods and makes the goods slide onto the bull's-eye wheel 25. After the goods are moved into the lifting platform 2, the return spring 332 drives the push rod 31 to reset. Under the clamping action of the limiting block 413 and the control block 414, it is difficult for the push rod 31 to swing away from the center of the lifting platform 2, so that the push rod 31 and the transition roller 311 form a protective effect on the goods.

[0077] The lifting motor 54 drives the lead screw 51 to rotate through the driving gear 53 and the lifting gear 52. The lead screw 51 drives the lifting platform 2 to move, so that the lifting platform 2 drives the goods to move. When it is necessary to remove the goods from one of the loading and unloading ports 11, the first electromagnet 322 and the second electromagnet 323 drive the slider 321 to slide. The slider 321 pushes the goods to move through the push rod 31 and the transition roller 311, and enables the push rod 31 in the direction of the goods being removed to swing away from the center of the lifting platform 2 through the driving oil cylinder 411 and the control oil cylinder 412. The goods push the push rod 31 in the direction of their own removal to swing, and move out of the lifting platform 2, so that the goods can be loaded and unloaded from any one of the loading and unloading ports 11, improving the docking effect between the elevator and the stereoscopic shelf.

[0078] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
