In addition, specific terms can be selected by the applicant, and in this case, its detailed meaning will be described in the detailed description of the utility model. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the term and the general description of the utility model.

[0027] Embodiment 1, refer to Figures 1 to 5 The embodiment provides a suction disc mechanism, comprising,

[0028] The base assembly 1 comprises a base 11, and one side of the base 11 is provided with a main connecting rod 12.

[0029] The suction assembly 2 comprises a first suction disc 21 arranged on the side, away from the main connecting rod 12, of the base 11, and a fixing plate 22 is coaxially arranged in the first suction disc 21, a plurality of first air holes 23 are arranged on the fixing plate 22, and a plurality of second suction discs 24 are further arranged on the fixing plate 22, and the openings of the first suction disc 21 and the second suction discs 24 are consistent.

[0030] The first suction disc 21 is a large suction disc with a large volume relative to the second suction disc 24, the second suction disc 24 is a plurality of small suction discs arranged in the first suction disc 21, and the ends, away from the base 11, of the first suction disc 21 and the second suction disc 24 are suction surfaces. In use, the suction surfaces of the first suction disc 21 and the second suction disc 24 face the concrete surface, the base 11 is pressed with force, air in the second suction disc 24 is discharged from the suction surface of the second suction disc 24, so that the second suction disc 24 is adsorbed to the concrete surface, air in the first suction disc 21 is discharged from the suction surface of the first suction disc 21, so that the first suction disc 21 is adsorbed to the concrete surface, and the first air holes 23 are arranged to enable air between the fixing plate 22 and the base 11 to be partially squeezed to the suction surface through the first air holes 23 when the first suction disc 21 is squeezed.

[0031] Since the first suction disc 21 and the second suction disc 24 and the plurality of second suction discs 24 are independent suction structures that are not connected to each other during suction, the first suction disc 21 and the plurality of second suction discs 24 can independently function to be adsorbed to the concrete surface, and the falling of the first suction disc 21 or individual second suction discs 24 caused by the rough surface and slight inclined surface of the local concave-convex surface of the concrete does not affect the overall adsorption of the group of second suction discs 24, so that the suction disc mechanism as a whole can adapt to most common concrete surfaces, and the stability of adsorption during use is ensured.

[0032] In the specific design, the end, away from the base 11, of the second suction disc 24 protrudes to the outside of the first suction disc 21, that is, the suction surface of the second suction disc 24 protrudes outward compared with the suction surface of the first suction disc 21, during suction, the second suction disc 24 first contacts the concrete surface and is squeezed to discharge air for adsorption, and then the first suction disc 21 is squeezed to discharge air for adsorption, thereby preventing the problem that the second suction disc 24 is difficult to adsorb due to the air in the second suction disc 24 being unable to be discharged caused by the second suction disc 24 being wrapped by the first suction disc 21 after adsorption, and the first suction disc 21 and the second suction disc 24 are made of the same material, such as a silica gel suction disc.

[0033] Further, refer to Figures 1 to 5Further comprising a ventilation assembly 3, the ventilation assembly 3 comprises a ventilation pipe 31 arranged on the base 11, the ventilation pipe 31 is provided with a valve 32, and a communication path 33 is arranged between the end of the first suction cup 21 close to the base 11 and the ventilation pipe 31.

[0034] Further, referring to Figures 1 to 5 , the ventilation assembly 3 further comprises a movable plate 34 coaxially arranged on the fixed plate 22 away from the base 11, the movable plate 34 is provided with a plurality of second ventilation holes 35 corresponding to the position of the first ventilation hole 23, and the second suction cup 24 is fixedly arranged on the movable plate 34, and the end of the second suction cup 24 close to the base 11 is attached to the fixed plate 22.

[0035] The two ends of the first suction cup 21 and the second suction cup 24 are both open, the non-suction surface of the first suction cup 21 is arranged on the base 11, and the non-suction surface of the second suction cup 24 is attached to the fixed plate 22, when suction, the base 11 is pressed to adsorb the entire suction cup mechanism to the surface of the concrete, the valve 32 is closed, the movable plate 34 is rotated, the first ventilation hole 23 on the fixed plate 22 and the second ventilation hole 35 on the movable plate 34 are opposite to the communication, at this time, the second suction cup 24 is dislocated with the first ventilation hole 23 on the fixed plate 22, the non-suction surface of the second suction cup 24 is closed through the fixed plate 22, when pressing, each second suction cup 24 first contacts the surface of the concrete, releases air, forms a smaller air pressure than the outside, and is pressed and adsorbed to the surface of the concrete by the external atmospheric pressure; then the first suction cup 21 contacts the surface of the concrete, releases the air in the first suction cup 21, forms a smaller air pressure than the outside, and is pressed and adsorbed to the surface of the concrete by the external atmospheric pressure, because the inside of the suction cup is not absolutely vacuum, at this time, due to the decrease of the air pressure in the first suction cup 21, the second suction cup 24 rebounds, when pressing again, the second suction cup 24 releases air again, enters the first suction cup 21, and is more tightly adsorbed to the surface of the concrete, unlike ordinary suction cups, the combination form of the large and small suction cups can make the air pressure in the suction cup more completely exhausted, provide stronger adsorption force and bearing capacity, with the continuation of pressing, the air in the first suction cup 21 will be exhausted again, and the air in the second suction cup 24 is exhausted as much as possible through multiple extrusions, and it is expected that 5-6 extrusions can firmly adsorb to the surface of the concrete in actual operation; when disassembling, the valve 32 is opened, the outside air enters the inside of the first suction cup 21 through the ventilation pipe 31 and the communication path 33, so that the inside of the first suction cup 21 and the outside atmospheric pressure are the same, the adsorption of the first suction cup 21 is released, but at this time, the second suction cup 24 is still adsorbed to the surface of the concrete, the base 11 is rotated, the fixed plate 22 and the movable plate 34 are relatively rotated, and then the second suction cup 24 and the first communication hole are communicated, the second suction cup 24 and the inside of the first suction cup 21 are communicated, air enters, and the adsorption of the second suction cup 24 is released.

[0036] The fixed plate 22 is provided with a plurality of rows of first air holes 23 in the radial direction, and the movable plate 34 is provided with a plurality of rows of second air holes 35 in the radial direction. The second suction cups 24 are arranged in the radial direction on the movable plate 34, and the second suction cups 24 and the second air holes 35 are arranged in the circumferential direction of the movable plate 34.

[0037] The fixed plate 22 and the movable plate 34 are both circular plates matched with the internal shape of the first suction cup 21. The outer edge of the fixed plate 22 is fixed to the inner wall of the first suction cup 21, and the outer edge of the movable plate 34 is rotatably installed on the inner wall of the first suction cup 21. Since the coaxial rotation of the circular plate on the circular inner wall is a common installation method, and this installation method is not the innovation point of the present application, the specific installation structure of the outer edge of the movable plate 34 will not be described here. In the specific design, the second suction cup 24 and the second air hole 35 are arranged in position corresponding to the first air hole 23, and the first suction cup 21 and the second air hole 35 are arranged in the circumferential direction of the movable plate 34. During suction, the first air hole 23 and the second air hole 35 are connected to exhaust the air in the first suction cup 21 for suction, and the second suction cup 24 is closed by the fixed plate 22 to make the second suction cup 24 perform extrusion suction. When disassembly is needed, the relative rotation of the movable plate 34 and the fixed plate 22 can make the second suction cup 24 and the first air hole 23 communicate, and the second suction cup 24 and the inside of the first suction cup 21 communicate, and air enters.

[0038] Embodiment 2, refer to Figure 1 and Figure 5 The base assembly 1 further comprises a hand holding rod 13 arranged on the main connecting rod 12, and the base assembly 1 further comprises a supporting rod 14 arranged between the base 11 and the main connecting rod 12.

[0039] The design of the hand holding rod 13 facilitates force application during extrusion suction and disassembly. Specifically, the hand holding rod 13 is designed as two and symmetrically fixed on both sides of the main connecting rod 12. During suction, both hands hold one hand holding rod 13 respectively and apply force towards the concrete wall surface. During disassembly, the air valve 32 and the first suction cup 21 are released from suction, and then both hands hold one hand holding rod 13 respectively and rotate with force, so that the base 11 drives the fixed plate 22 to rotate relative to the movable plate 34, the second suction cup 24 and the first air hole 23 are communicated, and the suction of the second suction cup 24 is released. The supporting rod 14 arranged between the base 11 and the main connecting rod 12 improves the connection firmness of the main connecting rod 12 and the base 11.

[0040] Further, refer to Figure 1 and Figure 2 The suction assembly 2 further comprises a clamp 25 sleeved on the outside of the first suction cup 21, and the first suction cup 21 is sealed and fixed to the base 11 through the clamp 25. The first suction cup 21 is a concertina suction cup.

[0041] The first suction cup 21 is fixed at one end of the base 11 by a clamp 25 in a sealed detachable manner. The first suction cup 21 is in the form of an accordion type suction cup, i.e. a corrugated suction cup. The corrugated structure can buffer vibration during construction, thereby ensuring strong stability.

[0042] Embodiment 3, refer to Figures 6 to 7 The present embodiment provides a hook for engineering construction, comprising the above-mentioned suction cup mechanism, further comprising,

[0043] The suspension assembly 4 comprises a hanging plate 41 arranged on the main connecting rod 12. The hanging plate 41 is in the form of a hook. A plurality of threading holes 42 are arranged on the hanging plate 41.

[0044] The hanging plate 41 is in the form of a hook. A plurality of threading holes 42 are arranged on the hanging plate 41. The diameters of the plurality of threading holes 42 can be the same or different. The diameters of the plurality of threading holes 42 are set according to actual use requirements. An operator can hang a cable, a strip-shaped lamp or the like on the hook-shaped portion of the hanging plate or pass the cable, the strip-shaped lamp or the like through the holes.

[0045] The hook with the above-mentioned suction cup mechanism is used to replace the suspension mode of reinforcing steel bars. The hook can avoid punching holes in a concrete surface and inserting steel bars, thereby ensuring the integrity and strength of the concrete. Meanwhile, there is no need to cut off temporary steel bars and fill holes, thereby reducing the possibility of internal steel bar corrosion. In addition, unlike ordinary suction cups, the combination of large and small suction cups can make the air pressure in the suction cups be completely discharged, thereby providing stronger suction force and bearing capacity.

[0046] Finally, it should be noted that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
