The support plate 6 and mounting plate 7 are both parallel to the bed frame 1, so that the mattress support 2 is parallel to the bed frame 1. Referring to fig. 2, when the storage bed frame is required to be changed from the retracted posture to the inclined posture, one end of the mattress support 2 is lifted, and the support plate 6 and the mounting plate 7 are still in the fixed posture, and the support plate 6 is rotated with respect to the mounting base 5, so that the support plate 6 and the mounting plate 7 are simultaneously in the inclined posture with respect to the bed frame 1. Therefore, the mattress support 2 is in an inclined posture relative to the bed frame 1, and the posture of the storage bed frame is changed. Referring to fig. 4, when the locker frame is required to be changed from the inclined posture to the horizontal posture, the unlocking of the circulation lock assembly 10 is completed by a jog upward. After the unlocking, the mounting plate 7 can rotate the mounting plate 7 relative to the supporting plate 6, and at the moment, the mounting plate 7 is applied with force to rotate relative to the supporting plate 6 until the mattress support 2 is parallel to the bed frame 1, and the storage bed frame finishes the posture conversion.

Referring to fig. 6, in order that the mattress support 2 does not excessively pivot when the storage bed frame is changed from the retracted posture to the inclined posture, one side wall of the connecting stub 9 includes an abutment plane 13. The end wall of one end of the connecting short rod 9 which is rotatably connected with the supporting plate 6 is a circular arc surface 14. The arc surface 14 is received by the abutting flat surface 13. The side wall fixedly connected with limiting plate 55 on mounting panel 7, limiting plate 55 perpendicular to mounting panel 7 and fixed connection in mounting panel 7.

Referring to fig. 6 and 7, when the storage bed frame is turned from the retracted posture to the inclined posture, the arc surface 14 of the connection short bar 9 abuts against the lower plane of the stopper plate 55 and slides with respect to the lower plane of the stopper plate 55. Until the abutment plane 13 of the connecting short rod 9 abuts against the lower plane of the limit plate 55, at which time the abutment plane 13 is located above the rotation point of the connecting short rod 9 and the pallet 6. The support plate 6 is pivoted to an extreme position relative to the connecting stub 9 so that the mattress support 2 does not over-pivot.

Referring to fig. 8 and 9, in order to keep the storage bed frame in a horizontal posture, the link assembly 3 is preferably kept stable. Be equipped with guide block 15 on the extension bar 8, guide block 15 is kept away from extension bar 8 one end and is equipped with stabilizing block 16, and guide block 15 and stabilizing block 16 an organic whole set up and form and support piece 17, support piece 17 and be the bolt. The abutting piece 17 is fixedly connected to the long connecting rod 8 through threads.

Referring to fig. 2 and 8, the side walls of the receiving groove 4 are provided with side stabilizers 18. The side stabilizer 18 is recessed away from the side wall of the middle portion of the bed frame 1 to form an abutment section 19. The abutting section 19 is located between the two ends of the side stabilizing piece 18, and the abutting section 19 is spaced from the inner wall of the accommodating groove 4. Both ends of the side stabilizer 18 are abutted against the inner wall of the accommodating groove 4, mounting bolts 20 are respectively arranged at both ends of the side stabilizer 18 in a penetrating manner, and the mounting bolts 20 are in threaded connection with the bed frame 1 and abut against the side stabilizer 18 against the inner wall of the accommodating groove 4.

Referring to fig. 8 and 9, the abutting section 19 is provided with a guide groove 21, and the guide groove 21 communicates with the lower end wall of the abutting section 19. The guide block 15 passes through the guide groove 21 and is slidably coupled to the guide groove 21. The side wall of the abutting section 19, which is away from the side wall of the middle part of the bed frame 1, is protruded to form an abutting platform 22, and one section of the guide groove 21 is positioned on the abutting platform 22. The abutting platform 22 is used for abutting the stabilizing block 16 towards the side wall of the guide block 15, and the abutting platform 22 is arranged obliquely.

Referring to fig. 9, when the storage bed frame is in the retracted position, the stabilizer block 16 and the side stabilizer 18 are disposed with a gap, and the stabilizer block 16 is in the a position. When the storage bed frame is in a horizontal posture, the stabilizing block 16 abuts against the abutting platform 22. When the storing bedstead changes into the slope gesture from retrieving the gesture, stabilizing block 16 is being close to butt platform 22 along the inclined plane of butt platform 22 gradually at the relative bed frame 1 pivoted in-process of connecting long rod 8 to support tightly with butt platform 22, stabilizing block 16 is in the B position. Thereby stabilizing the mattress support 2. When the storage bed frame is changed from the inclined posture to the horizontal posture, the long connecting rod 8 does not rotate any more, so the stabilizing block 16 is still tightly propped against the butt platform 22, and the mattress support 2 is kept stable.

Referring to fig. 2, in order to make the long connecting rods 8 on both sides abut against the abutting platform 22, a connecting frame 23 is arranged between the two support plates 6, and the two support plates 6 are both fixedly connected to the connecting frame 23. The two support plates 6 can move synchronously as far as possible through the connecting frame 23, so that the two long connecting rods 8 are driven to rotate synchronously.

Referring to fig. 4, in order to reduce the potential safety hazard caused by the sudden drop of the mattress support 2 when the storage bed frame is changed from the inclined posture to the horizontal posture, a thrust damping rod 24 is provided between the long connecting rod 8 and the mounting base 5. Thrust damping lever 24 is rotatably attached to mounting base 5 at one end and to long connecting rod 8 at the other end. When the mattress support 2 falls relative to the storage bed frame, the thrust damping rods 24 can play a certain role in buffering and supporting, so that the mattress support 2 can slowly rotate relative to the bed frame 1 to fall, and the safety is improved.

Referring to fig. 4, in order to change the posture of the storage bed frame in a labor-saving manner, a pneumatic rod 25 is arranged between the supporting plate 6 and the mounting base 5, a rod end of the pneumatic rod 25 is rotatably connected to the supporting plate 6, and a piston rod end of the pneumatic rod 25 is rotatably connected to the mounting base 5. The pneumatic rod 25 can push the supporting plate 6 to rotate relative to the mounting base 5, so that the storage bed frame can be changed from the withdrawing posture to the inclined posture more easily. A tension damping rod 29 is arranged between the mounting plate 7 and the supporting plate 6, the rod body end of the tension damping rod 29 is rotatably connected to the mounting plate 7, and the piston rod end of the tension damping rod 29 is rotatably connected to the supporting plate 6. The tension damping rod 29 can push the supporting plate 6 to rotate relative to the mounting plate 7, so that the storage bed frame can be changed from the inclined posture to the horizontal posture more easily.

Referring to fig. 4, in order to more stably maintain the storage bed frame in the artificially adjusted posture, a first lock lever 26 is rotatably coupled to the mounting base 5 of one of the link assemblies 3. Referring to fig. 10, a first locking plate 27 is fixedly provided on an upper end of the first locking lever 26, and the first locking plate 27 is perpendicular to the first locking lever 26. A first locking plate 27 has a first locking groove 28 formed at an end thereof facing away from the first locking bar 26.

Referring to fig. 10 and 11, when the storage bed frame is in the retracted position, the first locking plate 27 abuts against the outer wall of the rod body of the pneumatic rod 25, the rotation point of the first locking rod 26 and the mounting base 5 is located on the side of the center of gravity of the first locking rod 26 away from the pneumatic rod 25, and the relative position of the first locking rod 26 and the pneumatic rod 25 is as in state a.

When the storage bed frame rotates to an inclined posture from a withdrawing posture, the air pressure rod 25 rotates relative to the mounting base 5, the first locking plate 27 slides relative to the outer wall of the rod body of the air pressure rod 25 until the first locking plate 27 moves to the position of the piston rod of the air pressure rod 25, and at the moment, the storage bed frame just moves to the inclined posture. The relative position of the first lock lever 26 and the gas cylinder 25 is shown as state B. Correspondingly, the first locking plate 27 abuts against the end wall of the rod body end of the pneumatic rod 25 facing the piston end of the pneumatic rod 25, and the piston rod of the pneumatic rod 25 is embedded in the first clamping groove 28. At this time, the first locking plate 27 has a restraining force on the rod body of the pneumatic rod 25 so that it cannot move toward the rod body of the pneumatic rod 25, and thus the entire length of the pneumatic rod 25 is locked. The storage bed frame can be stably kept in an inclined posture.

If the storage bed frame needs to be changed from the inclined posture to the retraction posture, the first locking lever 26 can be manually rotated until the first locking plate 27 is separated from the pneumatic lever 25, and the relative position of the first locking lever 26 and the pneumatic lever 25 is in a state C. At this time, the rod body of the pneumatic rod 25 can move towards the rod body of the pneumatic rod 25, i.e. the whole length of the pneumatic rod 25 can be changed. Therefore, the mattress support 2 can smoothly rotate relative to the bed frame 1 only by applying a downward force to the upper end of the mattress support 2, and the posture is changed.

Referring to fig. 4 and 12, the link assembly 3 to which the first lock lever 26 is attached is provided with a second lock lever 30. The lower end of one end of the second lock rod 30 is rotatably connected to the supporting plate 6, the upper end of the second lock rod 30 is fixedly provided with a second locking plate 31, and the second locking plate 31 is perpendicular to the second lock rod 30. A second locking groove 32 is formed on one end of the second locking plate 31, which is far away from the second locking rod 30. The first locking bar 26 and the second locking bar 30 constitute a safety lock.

Referring to fig. 12 and 13, when the storage bed frame is in the inclined posture, the second lock plate 31 abuts against the outer wall of the rod body of the tension damping rod 29, and the rotation point of the second lock rod 30 and the support plate 6 is located on the side of the center of gravity of the second lock rod 30 away from the tension damping rod 29. The relative position of the second lock lever 30 and the tension damper lever 29 is shown as state D.

When the storage bedstead rotates from the inclined posture to the horizontal posture, the tension damping rod 29 rotates relative to the supporting plate 6, the second locking plate 31 slides relative to the outer wall of the rod body of the tension damping rod 29 until the second locking plate 31 moves to the position of the piston rod of the tension damping rod 29, and at the moment, the storage bedstead just moves to the horizontal posture. The relative position of the second lock lever 30 and the tension damper lever 29 is shown as state E. Correspondingly, the second locking plate 31 abuts against the end wall of the rod end of the tension damping rod 29 facing the piston end of the tension damping rod 29, and the piston rod of the tension damping rod 29 is embedded in the second locking groove 32. At this time, the second locking plate 31 has a restraining force on the rod body of the tension damper rod 29, so that the rod body cannot move towards the piston rod of the tension damper rod 29, and the overall length of the tension damper rod 29 is locked. The storage bed frame can be stably kept in a horizontal posture.

Referring to fig. 12 and 13, if the storage bed frame needs to be changed from the horizontal posture to the inclined posture, the second lock lever 30 can be manually rotated until the second lock plate 31 is separated from the tension damping lever 29, and the relative position of the second lock lever 30 and the tension damping lever 29 is in a state F. The rod body of the tension damper rod 29 can now move towards the piston rod of the tension damper rod 29, i.e. the overall length of the tension damper rod 29 can be varied. Therefore, the mattress support 2 can smoothly rotate relative to the bed frame 1 only by applying upward force to one end of the mattress support 2, and the posture is changed.

Referring to fig. 12 and 13, in order to maintain the second locking bar 30 at a position separated from the tension damper bar 29, a magnet 33 is installed on the tray 6, and when the second locking bar 30 is attached to the magnet 33, the second locking bar 30 is separated from the tension damper bar 29. In order to make the storage bed frame change from the horizontal posture to the inclined posture, the second lock rod 30 automatically leaves the magnet 33 and returns to the initial position abutting against the outer wall of the rod body of the tension damping rod 29, and a connecting lug 61 is extended on one side of the second lock rod 30. The connecting lug 61 is provided with a limiting rod 34. When the second lock rod 30 is attached to the magnet 33, the limiting rod 34 abuts against the side wall of the piston end of the tension damping rod 29, which is away from the second lock rod 30.

In the process that the storage bed frame is changed into the inclined posture from the horizontal posture, when the tension damping rod 29 rotates relative to the supporting plate 6, the tension damping rod 29 drives the connecting plate 42 to rotate relative to the supporting plate 6 by shifting the limiting rod 34, so that the second locking rod 30 is driven, the second locking rod 30 is separated from the magnet 33, and the second locking rod 30 is automatically reset to the initial position.

Specifically, referring to fig. 14 and 15, the circulation lock assembly 10 includes a safety plate 35, a rotary member 36, an upper retainer 37 and a lower retainer 38. The safety plate 35 is mounted on the side wall of the upper end of the mounting plate 7. Referring to fig. 6 and 15, a locking groove 43 for locking the supporting plate 6 is formed between the securing plate 35 and the mounting plate 7 at an interval. When the storage bed frame is in the retraction posture and the inclined posture, the supporting plate 6 is clamped in the clamping groove 43 and abuts against the lower plane of the limiting plate 55, so that the supporting plate 6 cannot move upwards relative to the mounting plate 7.

Referring to fig. 14 and 15, the rotating member 36 is rotatably connected to the supporting plate 6, and the upper and lower stoppers 37 and 38 are fixedly mounted on the mounting plate 7. The rotating member 36 is provided with an elastic member for preventing the rotating member 36 from rotating relative to the supporting plate 6, and the elastic member is a torsion spring 39. The torsion spring 39 is fixedly connected to the rotating member 36 and the supporting plate 6 at two ends, and the side wall of the rotating member 36 includes a first limiting plane 40 and a second limiting plane 41.

Referring to state 1 of fig. 6 and 16, when the storing bed frame is in the retracted posture and the inclined posture, the lower stopper 38 is located below the rotary member 36, and the first stopper plane 40 abuts against the lower stopper 38. So that the pallet 6 cannot easily move downwards relative to the mounting plate 7. At this time, the supporting plate 6 cannot move upward relative to the mounting plate 7 due to the cooperation of the limiting plate 55 and the supporting plate 6. Due to the cooperation of the rotating member 36 and the lower limiting member 38, the pallet 6 cannot easily move downward relative to the mounting plate 7. Locking of the pallet 6 and the mounting plate 7 is achieved.

Referring to the state 1 to the state 4 of fig. 16, when the storage bed frame needs to be turned from the inclined posture to the horizontal posture, one end of the mattress support 2 can be lifted upwards with force, at this time, the mounting plate 7 has a tendency of moving upwards relative to the supporting plate 6, and when the force is larger than the resistance force which needs to be overcome when the rotating member 36 rotates relative to the supporting plate 6, the rotating member 36 is forced to rotate relative to the supporting plate 6, so that the rotating member 36 does not receive the limit of the lower limiting member 38 any more, and the unlocking between the supporting plate 6 and the mounting plate 7 is completed. The mounting plate 7 rotates relative to the supporting plate 6 under the action of the tension damping rods 29, so that the mattress support 2 moves to a horizontal posture, and the storage bed frame completes posture conversion.

Referring to state 4 to state 7 of fig. 16, when the locker frame needs to be turned from the horizontal posture to the inclined posture, the rotating member 36 is synchronously moved with the pallet 6 with respect to the mounting plate 7. Until the rotating member 36 moves to the lower limit member 38, the lower limit member 38 can provide a guiding force to the rotating member 36, so that if the mounting plate 7 needs to rotate relative to the supporting plate 6, the resistance of the torsion spring 39 needs to be overcome, and the rotating member 36 rotates relative to the supporting plate 6, so as to jump over the obstruction of the lower limit member 38 to the rotating member and move to the upper side of the lower limit member 38. Then, the rotating member 36 continues to move with the supporting plate 6 relative to the mounting plate 7 until the rotating member 36 abuts against the upper limiting member 37, and the upper limiting member 37 guides the rotating member 36, so that the rotating member 36 rotates to an initial position (as shown in state 1 of fig. 16) relative to the supporting plate 6 under the action of the limiting of the upper limiting member 37 and the torsion force of the torsion spring 39, that is, the position where the first limiting plane 40 abuts against the lower limiting member 38. Meanwhile, the supporting plate 6 moves to a state of being caught in the catching groove 43 with respect to the mounting plate 7, and the supporting plate 6 abuts on the limit plate 55, thereby locking the mounting plate 7 and the supporting plate 6.

Specifically, referring to fig. 15, in order to facilitate the installation of the safety plate 35, the upper end of the safety plate 35 is bent to form a connecting plate 42, and the connecting plate 42 is fixedly installed on the lower plane of the limiting plate 55 by bolts or welding. Thereby fixedly mounting the safety plate 35 to the mounting plate 7. In order to facilitate the supporting plate 6 to enter the clamping groove 43, the lower end of the safety plate 35 is bent to form a guide plate 44 which is arranged obliquely relative to the safety plate 35, and the guide plate 44 guides the supporting plate 6 to enter the clamping groove. The upper end of the supporting plate 6 is bent towards the side away from the mounting plate 7, and is used for avoiding the upper limiting piece 37 and the lower limiting piece 38 when the supporting plate 6 is clamped into the clamping groove.

Referring to fig. 14, in order to facilitate the installation of the torsion spring 39, a groove 56 is formed on the support plate 6. A first fixing member 57 is fitted and fixed in the groove 56. The rotating member 36 is provided with an embedding groove 59, a second fixing member 58 is fixedly clamped in the embedding groove 59, and the second fixing member 58 is circumferentially and fixedly connected to the rotating member 36. The torsion spring 39 is accommodated in the groove 56, one end of the torsion spring 39 is fixedly connected to the first fixing member 57, and the other end of the torsion spring 39 is fixedly connected to the second fixing member 58 in a penetrating manner, so that the installation of the torsion spring 39 is realized. In order to make the second fixing member 58 more stably connected to the rotating member 36, a snap rivet 60 is disposed at an end of the rotating member 36 facing away from the supporting plate, the snap rivet 60 passes through the insertion groove 59 and is snap-fixedly connected to the second fixing member 58.

The implementation principle of two attitude storing bedstead of this application embodiment does:

under the initial gesture, storing bedstead is in retrieving the gesture, and mattress support 2 is located holding tank 4. At this time, the supporting plate 6 is clamped in the clamping groove 43, and the rotating piece 36 abuts against the lower limiting piece 38, so that the circular lock assembly 10 relatively fixes the mounting plate 7 and the supporting plate 6. The first locking plate 27 abuts against the outer wall of the rod body of the pneumatic rod 25, and the second locking plate abuts against the outer wall of the rod body of the tension damping rod 29.

When the storage bed frame is required to be turned into an inclined posture from a withdrawing posture, one end of the mattress support 2 is lifted upwards, at the moment, the supporting plate 6 and the mounting plate 7 rotate together relative to the bed frame 1 until the abutting plane 13 of the connecting short rod 9 abuts against the limiting plate 55, and the piston rod of the pneumatic rod 25 slides into the first clamping groove 28 in a clamping mode. At the moment, the storage bed frame reaches an inclined posture.

When the storage bed frame is required to be turned into a horizontal posture from an inclined posture, one end of the mattress support 2 can be forced to be lifted upwards, the rotating piece 36 is forced to rotate relative to the supporting plate 6, the rotating piece 36 is not limited by the lower limiting piece 38, and unlocking between the supporting plate 6 and the mounting plate 7 is completed. The mounting plate 7 rotates relative to the supporting plate 6 under the action of the tension damping rods 29, so that the mattress support 2 moves to a horizontal posture, and the storage bed frame completes posture conversion. Meanwhile, the piston rod of the tension damping rod 29 slides into the second slot 32, so that the storage bed frame can be stably kept in a horizontal posture.

When the storage bed frame is required to be turned from the horizontal posture to the inclined posture, the second locking rod 30 can be manually turned until the second locking rod is attracted to the magnet 33, so that the piston rod of the tension damping rod 29 is separated from the second clamping groove 32. Then upwards promote mattress support 2 one end, mounting panel 7 rotates for layer board 6, until layer board 6 card locate in the joint groove 43 to make the storing bed just accomplish the transformation of gesture. During this posture transition, the rotary member 36 passes over the lower stopper 38 and moves to a position where the first stopper plane 40 abuts against the lower stopper 38 under the guidance of the upper stopper 37, thereby locking the mounting plate 7 and the pallet 6. In the process, the tension damping rod 29 also rotates relative to the supporting plate 6, and the tension damping rod 29 drives the connecting plate 42 to rotate relative to the supporting plate 6 by shifting the limiting rod 34, so that the second locking rod 30 is driven, the second locking rod 30 leaves the magnet 33, and the second locking rod 30 automatically resets to the initial position.

When the storage bed frame is required to be turned from the inclined posture to the retraction posture, the first lock rod 26 can be manually turned to enable the piston rod of the pneumatic rod 25 to be separated from the first clamping groove 28. The end of the mattress support 2 is then pushed downwardly, whereupon the support plate 6 and mounting plate 7 rotate downwardly in unison relative to the frame 1. Until the mattress support 2 is embedded into the accommodating groove 4, the posture is changed.

Example 2:

referring to fig. 17, embodiment 2 is different from embodiment 1 in the way in which the rotary 36 is mounted on the pallet 6. The rotary member 36 is rotatably coupled to the support plate 6 by a coupling pin 46. The side of the supporting plate 6, which is far away from the rotating piece 36, is fixedly provided with a mounting lug 45, and the torsion spring 39 is positioned between the mounting lug 45 and the supporting plate 6. The connecting pin 46 penetrates through the rotating piece 36, the supporting plate 6, the torsion spring 39 and the mounting lug 45, one end of the connecting pin 46 is connected with a mounting nut 47 in a threaded mode, and the mounting nut 47 abuts against one side, away from the supporting plate 6, of the mounting lug 45. Thereby rotatably mounting the rotary member 36 to the tray 6 and stably mounting the torsion spring 39 at a predetermined position. In order to further stabilize the installation of the torsion spring 39, the installation tab 45 is provided with a circular truncated cone 62 toward the torsion spring 39, and the torsion spring 39 is sleeved on the circular truncated cone 62.

Referring to fig. 17, in order to better stably mount the mounting tab 45 on the supporting plate 6, the mounting tab 45 is bent to form a first connecting portion 48 for connecting the supporting plate 6 and a second connecting portion 49 for connecting the rotating member 36. The first connecting portion 48 abuts against the support plate 6 and is fixedly mounted on the support plate 6, and the second connecting portion 49 is spaced apart from the support plate 6. The supporting plate 6 is provided with a connecting bolt 50, and the connecting bolt 50 penetrates through the first connecting part 48. One end of the connecting bolt 50 is connected with a connecting nut 51 in a threaded manner, and the connecting nut 51 abuts against one side of the first connecting part 48, which is far away from the supporting plate 6. Thereby fixedly mounting the mounting tab 45 to the support plate 6.

Referring to fig. 17, in order to allow the torsion spring 39 to function as a stopper for the rotation of the rotary member 36, the supporting plate 6 is formed with an arc groove 52, and the rotary member 36 is fixedly provided with a biasing shaft 53 toward the supporting plate 6. The force application shaft 53 is slidably connected in the circular arc groove 52. And the urging shaft 53 is interposed between both ends of the torsion spring 39. The mounting lug 45 is in threaded connection with a fixing bolt 54 for tightly abutting one end of the torsion spring 39, and the fixing bolt 54 tightly abuts one end of the torsion spring 39 to fix one end of the torsion spring 39 relative to the supporting plate 6.

When the rotary member 36 rotates relative to the pallet 6, the urging shaft 53 pushes one end of the torsion spring 39 to move in abutment. Thereby increasing resistance to rotation of the rotary member 36. Meanwhile, the arc groove 52 and the force applying shaft 53 are matched, so that the rotating piece 36 can rotate relative to the supporting plate 6 along a preset track more stably. The locking and unlocking between the mounting plate 7 and the supporting plate 6 are more stable and smooth.
