Technical Field

The invention relates to a stress application controllable mechanism for lifting articles, in particular to a lifting article-placing mechanism which can be used for lifting articles at home kitchens and bathrooms and other higher positions only by lifting auxiliary equipment.

Background

The existing lifting object placing mechanism has more structural forms. The inventor designs a brand-new structure capable of generating ideal stress application controllable belt buffering effect and stably lifting the 'controllable force lifting object placing mechanism' when placing objects according to the problems existing in the lifting device of the existing life middle object placing cabinet, the controllable force lifting object placing mechanism is simple in structure, the manufacturing cost is lower compared with the existing lifting object placing mechanism, parts are reduced, the manufacturing process is simple, the stress application fit is more reasonable, the stress application is controllable, the assembly operation is convenient, the safety and reliability are improved, and the service life is prolonged. The left and right force control mechanisms composed of a damping buffer, a spring, an assistor and a fixed force rod which are assembled inside the force control mechanism shell are respectively and fixedly arranged on the left and right inner walls of the object cabinet. When in use, the shelf is pulled out from the storage cabinet by hand. When the commodity shelf runs downwards, the left main driving arm and the right main driving arm run downwards in parallel and drive the spring connected to the main driving arm to stretch to generate a reverse force, and meanwhile, the buffer damper is compressed to enable the commodity shelf to stably descend to the position of a polar point; the driven driving arms are respectively arranged on the left force application mechanism and the right force application mechanism and are fixedly connected in parallel by the connecting rods and are parallel to the main driving arms, so that the synchronous operation stability of the connecting device is ensured. When the main driving arm moves in a resetting way, the spring connected with the main driving arm also resets to generate a same-direction pulling force, and meanwhile, the damping buffer stretches and releases energy to slow down the resetting speed. However, if the rack cannot descend stably at a constant speed and can collide with the lower extreme position and cannot run stably when the weight of the rack is loaded, a force application mode must be added in the process to solve the existing problem, but a force application mode is added to enable the rack to descend stably at a constant speed to the lower extreme position and people usually need to take out articles in the rack at the moment, the rack can rapidly ascend and collide with the upper extreme position under the influence of the force application in the process of fetching the articles, a device for controlling the force application must be added to solve the existing problem, the existing force application device and the constant force rod can provide force application and force control effects in a part of heavy range, and therefore the mechanism is still to be improved.

The patent application No. 02132945.1 discloses a "lifting device", which uses three springs, a traction cable and a buffer device to store energy to achieve the functions of force application and buffer, and controls the lifting speed and the falling speed of a commodity shelf. The mechanism uses an access and release control device to enlarge the weight and control the stress application range, but can not realize the function of constant force when the commodity shelf descends to fetch the commodity after stress application. This is achieved by adding a set of fixed force levers in patent application No. 201911186482.3.

Detailed Description

The specific structure of the present invention will be described in detail with reference to FIGS. 1 to 12. The mechanism is improved on the basis of the structure of the original 'stress application lifting force article placing mechanism', except for basic structures of the article placing cabinet 1 in the original mechanism, the article placing shelf 2 assembled in the original mechanism, a left driving arm, a right driving arm 5, a left driven driving arm, a right driving arm 4, a left lifting controller, a right lifting controller and other parts, a group of force applying devices 3-06 and force fixing rods 3-08 are respectively arranged in the left control force control mechanism and the right control force control mechanism, the force applying capacity of the left force applying device 3-06 and the force applying capacity of the right force applying device 3-06 can be the same as or different from the balance force, and the force applying capacity can be the same as or; the left and right fixed force rods 3-08 can be used for controlling the force assistors 3-06 in the respective pulling-up states. The main driving arm 5 can also switch a handle switch 3-01 to control the booster 3-06 and the fixed force rod 3-08 during the lifting motion. The present booster 3-06 preferably has an extension spring also optionally extending a pneumatic cylinder and a cushion damper. The assistor 3-06 and one end of the fixed force rod 3-08 are concentrically hinged and fixed on the supporting shaft 3-07 of the control mechanism shell 3, and can also be hinged and fixed on the supporting shaft 3-07 of the control mechanism shell 3 in a sleeve way; the other end of the assistor 3-06 is fixedly connected with a hook 3-13. When the handle switch 3-01 is pulled out, the split fork 3-03 which is hinged and fixed on the supporting shaft 3-04 is driven, the torsional spring 3-05 which is buckled on the split fork 3-03 rotates by the supporting shaft 3-04, the other end of the included angle of the torsion spring 3-05 rotates to link the assistor 3-06 to rotate by the supporting shaft 3-07, the tension spring 3-23 in the assistor 3-06 also rotates by the supporting shaft 3-07 (see the schematic diagram 6), meanwhile, the handle switch 3-01 drives the split fork 3-10 which is hinged and fixed on the supporting shaft 3-11, the torsion spring 3-12 buckled on the split fork 3-10 rotates by the supporting shaft 3-10, the other end of the torsion spring with an included angle of 3-12 rotates and is linked with a nylon lantern ring 3-14 fixed on the fixed force rod 3-08 at the moment, so that the fixed force rod 3-08 rotates around a supporting shaft 3-07 (see a schematic diagram 6); conversely, the handle switch 3-01 is pushed in the opposite direction as described above with respect to the above-mentioned components (see fig. 5). After the handle switch 3-01 is pressed in, the shelf 2 is pulled out, the main driving arm 5 and the shaft lever 3-19 fixedly connected with the upper surface are driven to rotate downwards by the rotating shaft 3-21 and are buckled with the hook 3-13 to generate the force application effect of reverse tension when the tension spring 3-23 in the force application device 3-06 operates downwards relative to the shelf 2 (see a schematic diagram 8). The booster 3-06 is not needed to apply force in the no-load running process of the commodity shelf, the tension spring 3-16 is tensioned to apply reverse tension to the main driving arm 5 in the process of pulling the commodity shelf to downwards run to the down pole, meanwhile, the buffer damper 3-18 is contracted to apply damping speed reduction action to the running of the main driving arm 5, the tension spring 3-16 is tensioned to return to the original state in the process of resetting the commodity shelf 2 from the down pole to the up pole, and meanwhile, the buffer damper 3-18 is stretched and reset to apply damping speed reduction action to the running of the main driving arm 5; when the commodity shelf 2 bears the weight and the force-adding devices 3-06 apply force to the main driving arm 5 to pull the commodity shelf 2 to move downwards to the lower extreme point to take out the heavy object from the lower extreme point, the handle switch 3-01 (see the schematic diagram 10) can be pulled out before fetching the object, so that the torsion spring 3-12 buckled on the split fork 3-10 rotates by the supporting shaft 3-11, the other end of the included angle of the torsion spring 3-12 rotates and is linked with the nylon lantern ring 3-14 fixed on the fixed force rod 3-08 at the moment, so that the fixed force rod 3-08 rotates by the supporting shaft 3-07, the fixed force shaft 3-09 on the fixed force rod 3-08 is driven to be buckled with the hook 3-13, the tension spring 3-23 in the assistor 3-06 is always in a pulling-up state, and the tension force generated on the main driving arm 5 is stopped, so that the shelf 2 is stressed in a balanced state and cannot rise rapidly; on the contrary, when the fixed force shaft 3-09 on the fixed force rod 3-08 is buckled with the hook 3-13 to make the tension spring 3-23 in the assistor 3-06 always in a pulling-up state, the commodity shelf 2 is unloaded to move downwards from the upper extreme point to the lower extreme point and then put in a heavy object, the handle switch 3-01 (see the schematic diagram 9) can be pressed in, at this time, if the weight of the commodity shelf 2 is light, the commodity shelf 2 is pulled downwards with force, so that the fixed force rod 3-08 and the fixed force shaft 3-09 on the fixed force rod are driven by the rotation of the torsion spring 3-12 to rotate the support shaft 3-07 to return to the original position, the tension spring 3-23 in the booster 3-06 is not fixed to be in a pulling-up state all the time, the tension spring 3-23 in the booster 3-06 generates a lifting tension to the main driving arm 5, and at this time, the commodity shelf 2 reaches the stress balance and can be easily pushed to return to.

When the device is used, when a light object is placed in the storage rack 2, the storage rack can be normally pulled out and lifted without the aid of the aid 3-06, the tension spring 3-16 exerts reverse tensioning tension on the main driving arm 5 when the storage rack 2 is pulled out and moves downwards, and the buffer damper 3-18 is compressed to play a role in buffering and reducing the speed of the storage rack 2 during operation, so that the descending speed of the storage rack 2 is controlled and the storage rack can stably move to the position of a descending pole; when the commodity shelf 2 needs to be reset, the tension springs 3-16 are used for carrying out forward tightening tension on the main driving arm 5 when the commodity shelf 2 is pushed to move upwards, and the buffer dampers 3-18 are stretched to play a role in buffering and reducing the speed of the commodity shelf in operation, so that the ascending speed of the commodity shelf 2 is controlled.

When a heavier object is placed in the shelf 2, the force application capacity needs to be added for balancing, and only the handle switch 3-01 needs to be pressed, so that the torsion spring 3-05 buckled on the split fork 3-03 is driven to rotate by the support shaft 3-04, and the other end of the included angle of the torsion spring 3-05 rotates the linkage assistor 3-06 and the tension spring 3-23 at the moment, and the hook 3-13 fixed on the upper end rotates by the supporting shaft 3-07 at the same time, so that the shaft lever 3-19 fixed on the main driving arm 5 is buckled with the hook 3-13 when rotating downwards by the rotating shaft 3-21, and the tension springs 3-23 in the force adding devices 3-06 are driven to open and stretch to generate reverse tension force for downward running of the object placing rack 2 so as to achieve the effect of force adding balance, so that the object placing rack 2 stably descends to the position of the down pole and ascends to reset to the position of the up pole.

When a heavy object is placed in the commodity shelf 2, a larger force application capacity is needed to balance, and only the handle switches 3-01 and 6-01 are needed to be pressed simultaneously, so that the force applicators on the left side and the right side work simultaneously to control the descending speed and the ascending speed of the commodity shelf 2, and the force applicators stably descend to the position of the downstream pole and ascend to the position of the upstream pole.

When a heavy object put in the shelf 2 descends to the lower extreme and needs to be taken out, the tension spring 3-23 in the booster 3-06 needs to be fixed, so that the shaft lever 3-19 fixedly connected with the main driving arm 5 is not pulled any more, only the handle switch 3-01 needs to be pulled out, the torsion spring 3-12 buckled on the split fork 3-10 rotates by the supporting shaft 3-11, the other end of the included angle of the torsion spring 3-12 rotates and is linked with the nylon lantern ring 3-14 fixed on the fixed force rod 3-08 at the moment, so that the fixed force rod 3-08 rotates by the supporting shaft 3-07, the fixed force shaft 3-09 on the fixed force rod 3-08 is driven to be buckled on the hook 3-13, the tension spring 3-23 in the assistor 3-06 is always in a pulling-up state, and the object placing frame 2 achieves the effect of stress balance and cannot rapidly rise and reset to the upper limit.

When a heavy object placed in the object placing frame 2 descends to the lower extreme and needs to be taken out, the handle switches 3-01 and 6-01 need to be pulled out at the same time, the left and right fixed force rods simultaneously fix the force adding devices to work so as to control the rising speed of the object placing frame 2, and the object placing frame is stably raised and reset to the position of the upper extreme.

When the commodity shelf 2 descends to the lower extreme point without load and a heavy object needs to be put in again, a force application capacity needs to be added for balancing, before descending, the handle switch 3-01 is pressed again, the torsion spring 3-12 buckled on the opening fork 3-10 rotates by the support shaft 3-11, the other end of the included angle of the torsion spring 3-12 rotates and links the nylon lantern ring 3-14 fixed on the fixed force rod 3-08, the fixed force rod 3-08 rotates by the support shaft 3-07, the fixed force shaft 3-09 on the fixed force rod 3-08 is driven to be in the working state of disconnecting the hook 3-13, after a heavy object is put in, the commodity shelf 2 is pulled downwards to ensure that the fixed force shaft 3-09 completely disconnects the hook 3-13 (see the schematic diagrams of figures 10 and 11), and then the hook 3-13 of the force application device 3-06 is buckled with the shaft rod 3-19 fixedly connected on the driving arm 5 to generate a tensile force to, the shelf 2 can be easily pushed upwards to be reset to the upper pole position.

When the commodity shelf 2 descends to the lower extreme point in an idle state, heavy objects need to be placed again, a larger force application capacity needs to be added for balancing, and the handle switches 3-01 and 6-01 are pressed in before descending, so that the left and right fixed force rods restore the force application function of the force application device simultaneously to achieve the force application balance effect, and the commodity shelf 2 can be pushed upwards easily to reset to the upper extreme point.
