The present embodiment provides an absorption base 2, which also includes a rod 21, an assembly 22 and an absorption member 23, and is different from the first embodiment in that the absorption base 2 further includes a fixing member 24.

Referring to fig. 5 to 8, the absorption base 2 includes a rod 21, an assembly 22 and an absorption member 23, the rod 21 includes a rod 212 disposed on the rod 21 and a force-receiving portion 211 located at an end of the rod 212, the assembly 22 includes a surface contact fixing portion 221 contacting the absorption member 23, the surface contact fixing portion 221 is disposed on the absorption member 23, a first through hole 2211 adapted to the rod 212 of the rod 21 is disposed in the surface contact fixing portion 221, a second through hole 2311 adapted to the rod 212 of the rod 21 is disposed in the absorption member 23, and the rod 212 of the rod 21 is configured to sequentially penetrate through the first through hole 2211 and the second through hole 2311.

Here, when the force-receiving portion 211 enters the first force-receiving state, i.e. the separated state, i.e. one side of the force-receiving portion 211 pushes the elastic member 243 in a direction toward the fixed base 241, the elastic member 243 is pressed to the compressed state by one side of the force-receiving portion 211, so that the rod 21 tends to move in a direction approaching the fixed base 241 (downward direction in fig. 5 and 6), and meanwhile, the other side of the force-receiving portion 211 is pressed by a worker or other structures (downward pressing in fig. 5 and 6), and a part of the rod body 212 penetrates out of the adsorbing member 23, so that a preset gap is formed between the part of the rod body 212, the bottom surface of the adsorbing member 23, and the bearing surface. It should be understood that during the pressing process, the fitting member 22 and the suction member 23 are relatively stationary, and the rod member 21 has a movement process.

When the force-receiving portion 211 enters a second force-receiving state, i.e. an absorbing state, that is, the elastic member 243 in a compressed state pushes one side of the force-receiving portion 211 in a direction away from the fixed base 241, so that the rod 21 has a tendency to move in a direction away from the fixed base 241 (upward direction in fig. 5 and 6), and the limiting member 244 is used to prevent the tendency to limit the rod 21 on the fixed base 241, and since the other side of the force-receiving portion 211 is only limited by the limiting member 244 and is not pressed by a worker or other structures, the rod 212 does not penetrate out of the absorbing member 23 under the action of the elastic member 243. When the limiting member 244 stops, the rod 21 moves to the maximum stroke in the ascending direction, and the limiting member 244 contacts with the other side of the force-receiving portion 211 and applies an acting force opposite to the acting force of the elastic member 243, so as to limit the rod 21 in the fixing base 241.

Here, the limiting member 244 may include a limiting plate 2441, a pressing protrusion 2442 is provided on the limiting plate 2441, the pressing protrusion 2442 is provided on one end of the limiting plate 2441 contacting the pin 245, the pressing protrusion 2442 is provided on one side of the limiting plate 2441 close to the rod body 212, the pressing protrusion 2442 is provided facing the force receiving portion 211, and the pressing protrusion 2442 directly acts on the force receiving portion 211 when an external force is received.

In a specific structure of this embodiment, the elastic member 243 may be, but is not limited to, a spring, and the fixing base 241 may include a cylindrical base, a boss 2411 is disposed at a bottom of the cylindrical base, and the boss 2411 is located in a hollow portion of the spring. The boss 2411 may be located on the central axis of the spring, that is, a part of the spring is disposed around the boss 2411, preferably, the diameter of the boss 2411 is equal to or slightly smaller than the inner diameter of the spring, and then an elastic end of the spring may be engaged and fixed with the boss 2411.

The boss 2411 is provided with a through hole coaxially corresponding to the first through hole 2211, where the boss 2411 may be, but is not limited to, a circular boss. The limit plate 2441 may include a short plate 2443 and a long plate 2444 respectively located at both sides of the pin 245 to form a lever structure for saving labor. The pressing protrusion 2442 may include an arc-shaped convex section, an arc-shaped concave section, and a protrusion high point between the arc-shaped convex section and the arc-shaped concave section, wherein the starting end of the arc-shaped convex section is located on one side of the short plate 2443, and the protrusion high point is located on one side of the long plate 2444.

The spring is in a second compression state in an abnormal state, at this time, the force-receiving portion 211 is correspondingly in a first force-receiving state, the limiting plate 2441 rotates to a preset angle, so that the high point of the pressing protrusion 2442 on the limiting plate 2441 presses the force-receiving portion 211, and indirectly, the spring is compressed to the maximum extent, in this state, the rod body 212 is pressed by the pressing protrusion 2442 and extends out of the first through hole 2211 and the second through hole 2311, and a part of the rod body 212 penetrates out of the adsorbing member 23, so that a gap is formed between the adsorbing member 23 and the bearing surface, which is helpful for a worker to stably separate the adsorbing member 23 from the bearing surface adsorbed by the adsorbing member in a labor-saving manner.

It can be appreciated that the pressing protrusion 2442 has an arc-shaped convex structure, so that when the worker presses one side of the long plate 2444, the pressing protrusion 2442 can slide to the protrusion high point relatively slowly to place the elastic member 243 in the second compression state, so that the whole pressing process is smoother. Meanwhile, the arc-shaped concave portion of the pressing protrusion 2442 may form a self-locking structure, and specifically, after the limiting member 244 swings over the protrusion high point of the pressing protrusion 2442, the stressed portion 211 under the action of the elastic member 243 is held in the arc-shaped concave portion to form a fixed state. To release the self-locking structure, the stopper 244 may be swung in the opposite direction to allow the force-receiving portion 211 to slide toward the arc-shaped protrusion through the protrusion high point of the pressing protrusion 2442.

In this embodiment, the barrel edge of the barrel-shaped base body can also be used to limit the swing range of the short plate 2443 side of the limit plate 2441, so that when the force-receiving portion 211 is in sliding contact with the arc-shaped convex portion of the pressing protrusion 2442 to the preset contact position, the free end of the short plate 2443 of the limit plate 2441 abuts against the barrel edge, thereby limiting the limit piece 244 from continuing to rotate relative to the pin 245. In addition, the cylinder of the cylinder-type base body may further include a clearance structure disposed at one side of the long plate 2444 of the limiting plate 2441 for providing a larger swing space for the long plate 2444 and the pedals 245 thereon. In this embodiment, the structure of the assembly member 22 is the same as that of the assembly member 12 in the first embodiment, the assembly member 22 also includes an assembly rod 222 and a support 223, the surface contact fixing portion 221 includes a plate body, which may be but is not limited to an oval shape, the assembly rod 222 is disposed at an end position of the plate body far away from the first through hole 2211, and the assembly rod 222 extends in a direction far away from the adsorbing member 23. The support 223 extends along the side of the suction member 23 in a direction away from the plate. The difference from the assembly 21 of the first embodiment is that in this embodiment, no boss is disposed on the surface contact fixing portion 221, the boss structure is moved into the fixing base 241, and the plate body is fixedly connected to the fixing base 241 by the bolt 246.

The structure of the adsorbing member 23 is also the same as the structure of the adsorbing member 13 in the first embodiment, the adsorbing member 23 also includes a magnet 231 and a base cover 232 disposed on the magnet 231, and the second through hole 2311 is disposed in the middle of the magnet 231.

When in use, the pressing force-receiving portion 211 of the rod 21 makes the shaft 212 of the rod 21 in a state of not penetrating through the second through hole 2311 under the resilient action of the elastic member 243, and at this time, the adsorbing member 23 is placed on the bearing surface to realize adsorption and fixation. When the absorbing member 23 needs to be separated from the bearing surface, a worker can step on the pedal 2445 to press the force receiving portion 211 with the high point of the pressing protrusion 2442 on the limiting plate 2441, so that the shaft 212 of the rod 21 is pressed to partially penetrate out of the absorbing member 23, a gap is formed between the absorbing member 23 and the bearing surface, and the worker can realize stable separation operation between the absorbing member 23 and the bearing surface with small force. In the whole separation operation process, the staff only need apply right the pressing force of member 21, it is more laborsaving, can not right in the separation operation process adsorb piece 21 and cause the damage, still can avoid traditional absorption base to adsorb once more and cause the appearance of invalid action, adsorb the piece and destroy and cause situations such as potential safety hazard even on the loading end in the separation operation process simultaneously.

In summary of the first and second embodiments, the absorption base provided by the present invention includes a rod, an assembly member, and an absorption member, and receives an external torsion (rotational force) or a pressing force by using a force-receiving portion of the rod, so that the rod of the rod can be switched between passing through the absorption member and not passing through the absorption member: when the stress part is in a first stress state, part of the rod body penetrates out of the adsorption piece; when the force-bearing part is in the second force-bearing state, the rod body does not penetrate out of the adsorption piece. It should be noted that in one embodiment, the rod member is sequentially inserted into the assembly member and the suction member; in another embodiment, the rod is connected to the adsorbing member in a penetrating manner, the assembly member is arranged on the adsorbing member, and the rod is not required to be connected to the assembly member in a penetrating manner, so that the assembly member can be freely arranged on the adsorbing member. In the whole separation operation process of the adsorption base and the bearing surface, a worker only needs to apply small force, the adsorption part cannot be damaged in the separation operation process, and meanwhile, the situations that the traditional adsorption base adsorbs the adsorption base on the bearing surface again to cause invalid actions, the adsorption part is damaged and even potential safety hazards and the like in the separation operation process can be avoided.

All the parts in the invention can be respectively customized and produced, the assembly is flexible, and the structure is relatively simple and stable.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description, and do not represent the comparison between the advantages and disadvantages of the embodiments.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
