[0060] Referring to Figure 1 And Figure 2 The utility model provides a storage bed, including bedstead 100, row skeleton 200 and install on the anti-misoperation locking mechanism 300 of bedstead 100.

[0061] One end of the row skeleton 200 is hinged to the bedstead 100, and the other end is provided with a limiting column 200a for clamping with the anti-misoperation locking mechanism 300.

[0062] Referring to Figure 3 And Figure 4 The anti-misoperation locking mechanism 300 includes a locking mechanism housing 1, a rotating hook plate 2, a tension spring 3, and a rotating limiting piece 4.

[0063] The locking mechanism housing 1 is installed on the bedstead 100.

[0064] The upper end of the rotating hook plate 2 extends above the locking mechanism housing 1 to facilitate clamping with the row skeleton 200. The middle part of the rotating hook plate 2 is rotationally connected to the locking mechanism housing 1. The lower end of the rotating hook plate 2 extends below the locking mechanism housing 1 to form an operating portion 202.

[0065] The tension spring 3 connects the locking mechanism housing 1 and the rotating hook plate 2, and is used to drive the rotating hook plate 2 to rotate forward so that the upper end clamps the bedstead 100.

[0066] The rotating limiting piece 4 is rotationally installed on the locking mechanism housing 1 and located on the side of the rotating hook plate 2 away from the tension spring 3.

[0067] The rotating limiting piece 4 has a locked state in which it rotates to abut against the rotating hook plate 2 to limit the reverse rotation of the rotating hook plate 2, and an unlocked state in which it rotates to disengage from the rotating hook plate 2 to release the rotation limitation of the rotating hook plate 2.

[0068] The anti-misoperation locking mechanism 300 and the storage bed provided in the embodiment have the following working process:

[0069] S10: locked state

[0070] S101: the tension spring 3 continuously applies tension, causing the rotating hook plate 2 to rotate forward around the middle part of the rotating shaft.

[0071] S102: The upper end of the rotating hook plate 2 is kept in an outward convex state, and forms a rigid engagement with the row frame 200, thereby limiting the upward movement of the row frame 200 relative to the bed frame 100; at this time, a first locking is formed;

[0072] S103: The rotating limiting piece 4 is in a horizontal locking state, and the end thereof abuts against the rotating hook plate 2, thereby limiting the reverse rotation of the rotating hook plate 2; therefore, even if the operating part 202 of the rotating hook plate 2 is kicked in the reverse direction, the rotating hook plate 2 cannot be reversely rotated to release the row frame 200, thereby forming a second locking;

[0073] That is, the pulling spring 3 maintains the first locking in a basic state, and the rotating limiting piece 4 provides mechanical limiting of reverse rotation, thereby realizing the second locking;

[0074] S20: Unlocking operation

[0075] S201: The operator first rotates the rotating limiting piece 4 (about 90°) to an unlocking state, and releases the limiting constraint of the rotating limiting piece 4 on the rotating hook plate 2; this is the unlocking operation of the second locking;

[0076] S202: The operating part 202 is kicked, and the rotating hook plate 2 is reversely rotated against the pulling force of the pulling spring 3; this is the unlocking operation of the first locking;

[0077] S203: The upper end of the rotating hook plate 2 is separated from the row frame 200, and the locking of the row frame 200 is released; at this time, the row frame 200 can be freely opened to perform a storage operation.

[0078] Therefore, the anti-misoperation locking mechanism 300 and the storage bed provided by the utility model can realize reliable locking of the row frame 200, and further improve the use experience of users.

[0079] In the embodiment, the upper end of the rotating hook plate 2 is provided with a clamping groove 201 which is open and faces away from the pulling spring 3. Correspondingly, the row frame 200 is provided with a limiting column 200a which is used for clamping connection with the clamping groove 201. When the pulling spring 3 drives the rotating hook plate 2 to rotate in the forward direction, the upper end of the rotating hook plate 2 is rotated, so that the clamping groove 201 clamps the limiting column 200a, and further limits the upward movement of the row frame 200 relative to the bed frame 100.

[0080] In the embodiment, the middle part of the rotating hook plate 2 is provided with a plurality of rotating shaft holes 203 through which the rotating shafts pass, and the rotating shaft holes 203 are arranged in sequence along the vertical direction. The design core of each rotating shaft hole 203 is to realize accurate adaptation of mechanical properties of the mechanism by adjusting the installation position of the rotating shaft. The specific action is as follows:

[0081] The rotation axis position selection directly affects the force arm ratio of the operation part 202 (lower end) and the clamping groove 201 (upper end), and is suitable for the adaptation of the rib rack 200 made of different materials (such as steel which needs large force and wood which needs small force):

[0082] (1) When the rotation axis moves upward:

[0083] The force arm of the operation part 202 increases, and accordingly, the force required to kick the operation part 202 during unlocking decreases;

[0084] The stroke of the clamping groove 201 shortens, and accordingly, the stroke of the operation part 202 increases;

[0085] (2) When the rotation axis moves downward:

[0086] The force arm of the operation part 202 shortens, and accordingly, the force required to kick the operation part 202 during unlocking increases;

[0087] The stroke of the clamping groove 201 extends, and accordingly, the stroke of the operation part 202 decreases.

[0088] Optionally, a reinforcing sheath 7 is sleeved on the operation part 202. As the main force receiving part during unlocking, the operation part 202, which is provided with the reinforcing sheath 7, has improved structural strength, thereby avoiding the situation that the unlocking operation is blocked due to the deformation of the operation part 202.

[0089] In the embodiment, the rotation limiting part 4 includes a rotation baffle 401 rotationally connected to the locking mechanism shell 1 at one end, and a damping gasket 402 located between the rotation baffle 401 and the locking mechanism shell 1.

[0090] Optionally, the damping gasket 402 is a silica gel gasket, a rubber gasket, or a polyurethane gasket. The damping gasket 402 can increase the frictional resistance between the rotation baffle 401 and the locking mechanism shell 1, thereby avoiding the secondary locking failure caused by the natural downward rotation of the rotation baffle 401 under the action of gravity.

[0091] Further, the rotation baffle 401 is provided with a lever 403, and the rotation baffle 401 can be driven to rotate by operating the lever 403.

[0092] In the embodiment, the rotation hook plate 2 is provided with a limiting stop column 5 on the side close to the tension spring 3; the limiting stop column 5 is used to limit the rotation hook plate 2 in the unlocking state from continuing to rotate in the reverse direction.

[0093] Further, the locking mechanism shell 1 is provided with a threaded sleeve 6, and the limiting stop column 5 is arranged in the threaded sleeve 6 and is threadedly connected with the threaded sleeve 6. By screwing the limiting stop column 5, the distance between the limiting stop column 5 and the rotation hook plate 2 can be adjusted, and thus the maximum rotatable angle of the rotation hook plate 2 can be adjusted.

[0094] In this embodiment, the locking mechanism housing 1 is internally fixed with an axial limiting piece 8, which is provided with a U-shaped limiting groove 801 for the rotating hook plate 2 to pass through. The U-shaped limiting groove 801 can limit the rotating hook plate 2 from excessive displacement or excessive deformation in the axial direction of the rotating shaft, thereby improving the reliability of the anti-misoperation locking mechanism 300.

[0095] The anti-misoperation locking mechanism 300 and the storage bed provided in this embodiment have the following advantages:

[0096] (1) Double insurance locking mechanism

[0097] The "one-time locking" maintained by the tension spring 3 and the "secondary locking" of the rotating limiting piece 4 provide double protection. Through the cooperation of physical clamping and mechanical limiting, the accidental unlocking of the rib rack 200 caused by misoperation or external force impact is completely avoided, and the safety redundancy is significantly improved.

[0098] (2) Dynamic mechanical adaptation design

[0099] The rotating hook plate 2 is provided with vertically arranged rotating shaft holes 203 in the middle. By adjusting the rotating shaft installation position, the following can be achieved:

[0100] ① Precise matching of the force arm of the operating part 202 and the stroke of the clamping groove 201 (moving the rotating shaft up reduces the unlocking force but increases the stroke, and moving the rotating shaft down is the opposite)

[0101] ② Adapt to the mechanical requirements of rib racks 200 made of different materials such as steel and wood, with extremely strong versatility

[0102] (3) Anti-fatigue operation structure

[0103] The operating part 202 is additionally provided with a reinforcing sheath 7 to avoid deformation caused by repeated kicking and to prolong the service life of the mechanism while reducing the unlocking operation resistance.

[0104] (4) Self-locking limiting assembly

[0105] The rotating limiting piece 4 is integrated with a damping gasket 402 (silicone / polyurethane), which uses friction resistance to prevent spontaneous rotation under the action of gravity, ensuring the stability of the secondary locking state and avoiding the risk of failure caused by mechanical vibration.

[0106] (5) Adjustable motion boundary control

[0107] The threaded sleeve 6 is designed in cooperation with the limiting stop column 5 to adjust the maximum rotation angle of the rotating hook plate 2 by screwing, which can match the clamping depth of rib racks 200 of different thicknesses and optimize the user's operation feel.

[0108] Finally, it should be noted that the above embodiments have been described in the specification and drawings of the application, but this does not limit the patent protection scope of the application. Any equivalent structure or equivalent process replacement or modification based on the essential concept of the application, using the content described in the specification and drawings of the application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the application.
