Example 2
On the basis of embodiment 1, as shown in fig. 2, the device further comprises a pulling mechanism 7, the pulling mechanism 7 comprises a u-shaped rod 71, a movable wire guiding wheel 73, a first wire guiding wheel 74, a second wire guiding wheel 75 and a pulling rope 76, the front and rear parts of the right side of the outer bottom of the hanging basket 1 are both provided with L-shaped grooves 72, the L-shaped grooves 72 are located at the left side of the groove 61, the movable wire guiding wheel 73 is slidably arranged in the L-shaped grooves 72, the first wire guiding wheel 74 is rotatably installed at the right side of the upper part of the L-shaped grooves 72, the front and rear parts of the right side of the outer bottom of the hanging basket 1 are both provided with sliding grooves 77, the sliding grooves 77 are located at the left side of the L-shaped grooves 72, the u-shaped rod 71 is slidably arranged between the sliding grooves 77 at the front, the front and rear pull ropes 76 respectively pass through the hanging basket 1 and are fixedly connected with the inner sides of the upper parts of the left side surfaces of the front and rear grille doors 3 by respectively bypassing the second guide wheels 75, the movable guide wheels 73 and the first guide wheels 74.
When hanging flower basket 1 installed and placed on ground, hanging flower basket 1 still drives u type pole 71 and ground contact, ground makes u type pole 71 rebound, stay cord 76 is loosened, because of the effect of gravity, movable wire wheel 73 rebound makes stay cord 76 be in the state of tightly stretching tightly, so, avoid stay cord 76 to break away from with first wire wheel 74 and influence the use, and then when card pole 64 and draw-in groove 5 break away from, because of torsion spring 4's effect, grid door 3 swings ninety degrees right and opens, grid door 3 swings right and drives stay cord 76 and move right, stay cord 76 moves right and drives movable wire wheel 73 rebound and reset. When the hanging basket 1 drives the constructor to move upwards, the hanging basket 1 drives the u-shaped rod 71 to be separated from the ground, due to the action of gravity, the u-shaped rod 71 moves downwards to drive the pull rope 76 to move downwards, and the u-shaped rod 71 drives the grating door 3 to swing leftwards through the pull rope 76 to reset. So, need not constructor pulling grid door 3 and swing left and reset labour saving and time saving.
Example 3
On the basis of the embodiments 1 and 2, as shown in fig. 2, the hanging basket further comprises guide rods 8 and contact plates 9, the guide rods 8 are slidably arranged at the front and rear parts of the right side of the outer bottom of the hanging basket 1, the guide rods 8 are positioned at the front and rear sides of the groove 61, the contact plates 9 are fixedly connected between the bottom ends of the front and rear guide rods 8, and the top parts of the contact plates 9 are in contact fit with the outer ends of the swing plates 62.
The grating door structure is characterized by further comprising an arc-shaped plate 10, the arc-shaped plate 10 is fixedly connected to the rear side of the lower portion of the left side face of the front side grating door 3 and the front side of the lower portion of the left side face of the rear side grating door 3, and the arc-shaped plate 10 is matched with the clamping rod 64.
When the hanging basket 1 is placed on the ground, the hanging basket 1 drives the contact plate 9 to contact with the ground through the guide rod 8, the ground enables the contact plate 9 to move upwards, the contact plate 9 moves upwards to drive the outer end of the swing plate 62 to swing upwards, and the clamping rod 64 is separated from the clamping groove 5. When the hanging basket 1 drives the constructor to move upwards, the contact plate 9 is separated from the ground, the contact plate 9 moves downwards to reset under the action of gravity, and the outer end of the swinging plate 62 also swings downwards to reset. Thus, the situation that the outer end of the swing plate 62 is contacted with the concave part of the ground and cannot swing upwards to cause the clamping rod 64 not to be separated from the clamping groove 5 can be avoided.
When the grille door 3 swings to the right to be opened, the grille door 3 also drives the arc-shaped plate 10 to swing to the right, and the arc-shaped plate 10 swings to the right to block the clamping rod 64. When the grille door 3 swings leftwards and closes, the grille door 3 drives the arc-shaped plate 10 to swing leftwards and reset. Therefore, the situation that impurities fall between the clamping rod 64 and the hanging basket 1 to cause the sliding failure and influence the use can be avoided.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
