[ detailed description ] embodiments

Referring to fig. 1 to 5, the composition of the locking structure of the storage bed of the present invention is shown. The locking structure of the storage bed comprises a lock body 1 and a locking plate 2 which is matched with the lock body 1 to realize locking, wherein the lock body 1 is constructed on one of a bed board or a bed frame, and the locking plate 2 is constructed on the other of the bed board or the bed frame. For convenience of operation, it is preferable that the lock body 1 is generally installed on a bed plate and the locking plate 2 is installed on a bed frame.

The lock body 1 comprises a lock sleeve 11 and a bolt 12 accommodated in the lock sleeve 11. The bolt 12 is at least partially arranged inside the lock sleeve 11 in the unlocked state; the locking tongue 12 is arranged at least partially outside the lock sleeve 11 in the locked state. The locking is effected from the inside of the lock sleeve 11 to the outside. The lock body 1 also has at least one spring device 14, which spring device 14 elastically preloads the bolt 12 from the inside of the lock sleeve 11 to the outside of the lock sleeve 11. The latch bolt 12 includes a stopping portion 122 and a guiding portion 121, and the guiding portion 121 guides the latch bolt 12 to move toward the inside of the lock sleeve 11 relative to the lock sleeve 11, or the guiding portion 121 guides the latch bolt 12 to move toward the lock sleeve 11, so that the latch bolt 12 can smoothly perform a translational or rotational movement relative to the lock sleeve 11. In the process of realizing locking, after the lock tongue 12 crosses the lock plate 2, the lock tongue 12 extends out of the lock sleeve 11, and the stopping part 122 is matched with the lock plate 2 to realize locking. In the present embodiment, only the specific structure of the lock tongue 12 that can translate relative to the lock sleeve 11 is shown, but the present invention does not limit the movement mode of the lock tongue relative to the lock sleeve, and can freely select rotation or translation. The bolt 12 is adjustably mounted on the lock sleeve 11, in the embodiment, the bolt 12 is mounted on the lock sleeve 11 through an adjusting screw 15, the length of the bolt 12 extending out of the lock sleeve 11 can be adjusted through the adjusting screw 15, and a scale indication is arranged on the bolt 12 to indicate the length of the bolt 12 extending out. The guide portion 121 is configured as a chamfer made on the latch bolt 12. The lock body 1 further has an operating portion 13 operable on the lock tongue 12 so that the lock tongue 12 moves relative to the lock case 11. In the present embodiment, the operation portion 13 is configured as a rope connected to the latch bolt 12, and the unlocking is realized by pulling the operation portion 13, but the specific structure of the operation portion 13 is not limited in the present embodiment, and the structure in which the latch bolt 12 is displaced relative to the lock case 11 by the operation of the operation portion belongs to the protection scope of the present invention.

In another embodiment of the present invention, the storage bed locking structure further comprises a labor-saving lever 16a, the labor-saving lever 16a is rotatable around an axis 17a provided in the lock sleeve 11a, the lock tongue 12a is biased outwards from the inside of the lock sleeve by the elastic device 14a in the locked state, and in order to achieve the unlocked state, the labor-saving lever needs to be pulled or pressed outwards of the lock sleeve against the force of the elastic device 14a, so that the lock plate 2a is disengaged from the lock tongue 12 a. Optionally, an operating portion 13a, such as a cord, is attached to the power-saving lever 16a to pull the cord against the force of the elastic means; the labor-saving lever 16a can be pressed to overcome the force of the spring device, so that the locking plate is disengaged from the lock tongue, namely, the operating part is constructed on the labor-saving lever. Advantageously, in order to save effort, the position of the axis of rotation of the laborsaving lever is specifically set, the point of action of the laborsaving lever against the action of the spring means is set as a third action 163a, the position of the connection of the lock sleeve to the laborsaving lever and the position of the axis are set as a second action 162a, and the point of action of the laborsaving lever on the bolt is set as a first action 161a, the distance from the first action to the second action being smaller than the distance from the second action to the third action.

The lock plate 2 is provided with a roller 22 and a roller 21, the roller 22 can rotate around the roller 21, and the roller 22 contacts the latch bolt 12 during unlocking. The position that the lock plate 2 and spring bolt 12 contact sets up gyro wheel 22, and the frictional force when effectively reducing the unblock to reduce the required power of unblock.

In the utility model, when the bed board is pressed to move downwards, the lock tongue is retracted after contacting the lock plate, and after the lock tongue passes over the lock plate, the lock tongue is stretched out again under the action of the elastic device 14, at the moment, the bed board is pressed to continue to move downwards, the lock tongue is completely separated from the lock plate, and the possibility of interference collision is avoided. Due to errors of installation and part sizes, the distance between the bed board and the bed frame can be changed within a large range (nearly 15mm), so that the distance between the lock tongue and the lock plate is also changed, and if the distance is too large, the locking structure cannot be locked; if the distance is too close, the lock tongue interferes with the lock plate. Therefore, in the utility model, the extending length of the bolt relative to the lock sleeve can be adjusted, and the distance between the bolt and the lock plate is ensured to be in a proper range; or a kidney-shaped hole 18a can be arranged on the lock sleeve, and a screw passes through the kidney-shaped hole 18a to adjust the installation position of the lock body on the bed plate, so that the distance between the lock tongue and the lock plate is ensured to be within a proper range, and normal locking can be realized.

In an exemplary embodiment of the utility model, the process of locking is realized in such a way that the bed board drives the lock body to press downwards, the lock tongue retracts to the lock sleeve under the action of pressure after the lock tongue is contacted with the lock locking plate, and the lock tongue pops out under the action of the elastic device after the lock tongue is separated from the lock locking plate. At the moment, the lock tongue is blocked by the locking plate and cannot move upwards; the process of realizing the unblock does, the operator operation operating portion to drive the spring bolt removal, make the spring bolt atress withdraw the lock sleeve, the spring bolt staggers with the lock plate position, but the bed board upward movement realizes that the bed board is opened.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
