The embodiment also discloses an enclosure bed which comprises the folding type automatic return supporting leg structure.
This embodiment also provides an enclosure comprising a folding self-return foot structure as described above. Therefore, the supporting leg mechanism can be rotated to a folding state or an unfolding state only by moving the enclosing bed, complex operation is not needed, and the use convenience is improved.
The working principle of the folding type automatic return supporting leg structure is as follows:
when the support leg mechanism and the bedstead are in the unfolding state, the support leg mechanism and the bedstead are locked by the locking mechanism, so that the support leg mechanism and the bedstead are kept in the unfolding state, the support leg mechanism and the bedstead are kept in the unfolding angle, the condition that the folding state is changed between the support leg mechanism and the bedstead when the movable bedstead is used is avoided, the normal movement of the bedstead is influenced, and under the unfolding state, the bedstead moves smoothly and can keep a good use state. After using locking mechanical system to carry out the unblock to stabilizer blade mechanism and bedstead, moving the bedstead, when moving the bedstead, stabilizer blade mechanism can rotate relative to the bedstead automatically, and stabilizer blade mechanism and bedstead can convert fold condition into at the expansion state promptly, and stabilizer blade mechanism and bedstead also can convert the expansion state into at fold condition, and after stabilizer blade mechanism and bedstead converted the expansion state into at fold condition, locking mechanical system was automatic with both locks, makes both keep the expansion state. In the unlocked state, the leg mechanism can be switched between the folded state and the unfolded state.
The locking mechanism limits the rotation of the support leg body by inserting the directional bolt into the directional clamping groove, so that the support leg body and the bedstead are kept in an unfolded state. When the locking mechanism unlocks, the unlocking key is pressed down, the unlocking key is pressed on the directional bolt, the directional bolt compresses the directional spring and then breaks away from the directional clamping groove, and at the moment, the support leg body can rotate relative to the bedstead. When the supporting leg body rotates to the unfolding position, the orientation bolt corresponds to the orientation clamping groove in position, and the orientation spring enables the orientation bolt to be inserted into the orientation clamping groove so as to lock.
The locking mechanism inserts the directional bolt into the directional clamping groove through the directional spring arranged between the directional bolt and the bedstead, and the directional bolt is clamped with the directional clamping groove, so that the rotation of the relative bedstead of the support leg body is limited, and the support leg body and the bedstead are kept in an unfolded state. When the locking mechanism needs to be unlocked, the unlocking key is pressed down, the unlocking key is pressed on the directional inserting pin when the reset spring is compressed, the directional inserting pin is separated from the directional inserting groove after the directional inserting pin compresses the directional spring, the directional inserting pin is not clamped with the directional inserting groove, the rotation of the supporting leg body relative to the bedstead is not limited any more, the supporting leg body can rotate relative to the bedstead at the moment, and the unlocking key is ejected out of the supporting leg body under the action of the reset spring after the unlocking key is loosened, so that the next unlocking is performed. When the foot body can rotate relative to the bedstead, the directional spring keeps the compressed state, and when the supporting leg body rotates to the unfolding position, the position of the directional bolt corresponds to that of the directional clamping groove, and the directional spring enables the directional bolt to be inserted into the directional clamping groove, so that the locking is carried out.
The unlocking key is pressed down, the unlocking key is pressed on the directional bolt while compressing the reset spring, after the unlocking key is loosened, the unlocking key is ejected out of the supporting leg body under the action of the reset spring, and the reset spring ejects the unlocking key to the original initial position when the unlocking key is not pressed down.
After the unlocking, the supporting leg body can rotate to a folding state from an unfolding state relative to the bedstead, and when the bedstead is pulled reversely along the folding position, the universal wheels on the supporting leg body rub with the ground, so that the supporting leg body lags behind the movement of the bedstead, and the supporting leg swings to the folding position along with the supporting leg body. The stabilizer blade body rotates to the expansion state from fold condition relative the bedstead, and when pulling the bedstead along the folding position direction, the universal wheel on the stabilizer blade body rubs with ground, makes the stabilizer blade body fall behind the removal of bedstead, and the stabilizer blade swings thereupon to the expansion position.
When the support leg is in an unfolded state, the plug pin part on the positioning plug pin is inserted into the directional clamping groove, so that the support leg body and the bedstead are kept in the unfolded state. When carrying out the unblock through locking mechanical system, unblock button roof pressure location bolt for bolt portion breaks away from directional draw-in groove, and bolt portion breaks away from directional draw-in groove after, the rotatory stabilizer blade body of relative bedstead, makes inclined plane and inclined clamping groove cooperation, thereby makes the stabilizer blade body rotate to folding position on.
The operating principle of the enclosure bed is as follows:
