Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 6, the present invention includes a bottom plate 1, an object placing plate 2 fixed on the bottom plate 1 is arranged above the bottom plate 1, a movable plate 3 capable of moving up and down between the bottom plate 1 and the object placing plate 2 is arranged below the object placing plate 2, a plurality of cylinders 4 are arranged above the bottom plate 1, a boss is arranged on each cylinder 4, the cylinder 4 above the boss penetrates through the movable plate 3 and the object placing plate 2, and a structure that the cylinder 4 can slide up and down on the movable plate 3 and the object placing plate 2 is formed; a thrust spring 5 is sleeved on the cylinder 4 below the boss, the upper end of the thrust spring 5 is contacted with the boss, and the lower end of the thrust spring 5 is contacted with the bottom plate 1, so that a structure that the cylinder 4 moves up and down through the thrust spring 5 is formed;
the movable plate 3 is provided with a plurality of connecting blocks 6 arranged below the movable plate 3, the connecting blocks 6 are provided with straight grooves 7 which run through from front to back, sliding rotating shafts 8 are arranged in the straight grooves 7, the sliding rotating shafts 8 are connected with each other to form a linkage part, the sliding rotating shafts 8 are sleeved with connecting rods 9, the connecting rods 9 are arranged in parallel, one ends of the connecting rods 9 are hinged to the bottom plate 1, one of the connecting rods 9 is connected with an operating rod 10, and a structure that the connecting rods 9 rotate on the bottom plate 1 in the same direction through the operating rod 10 and the linkage part is formed.
In order to achieve a better using effect, the distance between the upper end surface of the cylinder 4 and the upper end surface of the object placing plate 2 is smaller than the distance between the lower end surface of the cylinder 4 and the upper end surface of the bottom plate 1; the distance between the lower end surface of the cylinder 4 and the lower end surface of the movable plate 3 is not more than the height of the thrust spring 5 when the thrust spring 5 is completely compressed.
In order to achieve a better linkage effect between the movable plate 3 and the cylinder 4, when the upper end surface of the movable plate 3 contacts with the lower end surface of the object placing plate 2, the upper end surface of the boss on the cylinder 4 contacts with the lower end surface of the movable plate 3, and the thrust spring 5 is in a compressed state or a critical state before compression.
In order to achieve a better using effect of the invention, the upper end surface of the cylinder 4 is provided with anti-skid grains.
When the article placing device is used, articles are placed on the article placing plate 2, and each group of the cylinders 4 is independently matched with the thrust spring 5, so that the cylinders 4 in the area range slide downwards and compress the thrust springs 5 under the action of the gravity of the articles according to the contact area of the articles and the article placing plate 2, and the upper parts of the cylinders 4 outside the area range are kept extending above the article placing plate 2, so that the horizontal displacement of the articles on the article placing plate 2 is blocked; the upper end surface of the cylinder 4 is provided with the anti-skid lines, so that the friction force between the cylinder 4 and an object is increased, and the object cannot easily generate horizontal displacement; meanwhile, the upper end face of the cylinder 4 is in real-time extrusion contact with the articles due to the upward thrust when the thrust spring 5 is in a compressed state, and the articles bump in the transportation process and can play a certain buffering role when falling.
When the article needs to be unloaded, the power device or the manual operation is used for pulling the operating rod 10, so that the operating rod 10 drives the connecting rod 9 to rotate on the bottom plate 1 along the hinge shaft in a counterclockwise circumferential manner, and the circumferential rotation of the connecting rod 9 drives the other connecting rods 9 to rotate in the same circumferential direction through the linkage piece; one end of the connecting rod 9 connected with the connecting block 6 is a movable end, the circumferential rotation of the movable end is decomposed into translational motion along the length direction of the straight groove 7 and linear motion vertical to the direction of the straight groove, the translational motion enables a sliding rotating shaft 8 connected with the movable end of the connecting rod 9 to slide leftwards in the straight groove 7, and the linear motion enables a movable plate 3 connected with the connecting rod 9 through the sliding rotating shaft 8 and the connecting block 6 to move linearly towards the direction of the bottom plate 1; the linear motion of the movable plate 3 causes the movable plate 3 to be in extrusion contact with the boss and drives the cylinder 4 to slide on the object placing plate 2 towards the direction of the bottom plate 1 through the boss, and meanwhile, the thrust spring 5 is compressed;
when the downward slip of cylinder 4 made the up end of cylinder 4 move to with put the up end parallel and level of thing board 2, cylinder 4 no longer produced the barrier effect to article, put the article on the thing board 2 and can remove and unload this moment, or the slope put the thing board and make article landing.
After the articles are unloaded, the acting force on the operating rod 10 is removed, under the thrust action of the compressed thrust spring 5, the cylinder 4 moves upwards and drives the movable plate 3 to move upwards through the boss, the movable plate 3 moves to enable the connecting rod 9 connected with the movable plate 3 through the connecting block 6 and the sliding rotating shaft 8 to generate resetting rotation, when the movable plate 3 moves to the upper end face of the movable plate and contacts with the lower end face of the object placing plate 2, the movable plate 3, the cylinder 4, the thrust spring 5 and the connecting rod 9 all complete resetting and do not move any more, and at the moment, the operating rod 10 resets along with the connecting rod 9.
In the resetting process, a certain acting force is applied to the operating rod 10 to enable the operating rod to rotate clockwise, so that the resetting process can achieve a better effect.
According to different service environments and requirements, the arrangement mode of the cylinders 4 is adjusted and changed, so that articles with different specifications or packaged articles can be reliably fixed without horizontal displacement when placed at any position on the object placing plate 2.
The article limiting and releasing device is ingenious in structure and convenient and fast to operate, the article limiting and releasing can be completed only by controlling the operating rod, the article transportation safety is improved, manpower and material resources required for fixing the position of an article in the loading process are saved, the article transportation efficiency is greatly improved, the manpower cost is reduced, the safety accident in manual fixing can be effectively avoided, and the article limiting and releasing device is particularly suitable for single-layer loading of the article. Meanwhile, due to the upward thrust generated when the thrust spring is compressed, bumping of the articles in the transportation process can be effectively buffered, and the integrity of the articles is protected to a certain extent.
