[0003] When installing equipment using these two methods, the supporting surface is often damaged, and it is inconvenient to disassemble, and the operation and maintenance costs are high. In addition, the impact and vibration resistance are poor, and the equipment position is not stable. Utility Model Content

[0007] A further purpose of the utility model is to improve the sealing performance between the suction cup and the inner core, thereby increasing the suction force of the suction cup and making it more stable after adsorption.

[0008] In particular, the utility model provides an adsorption type support device, which is used to be arranged between a supported device and a supporting surface to carry the supported device, and includes:

[0009] The outer cylinder has a bottom which is concave upward to form a truncated cone-shaped cavity which tapers from bottom to top, and a cavity wall of the cavity is provided with at least one positioning groove;

[0010] The suction cup is a truncated cone-shaped cylinder made of elastic material, part of which is located in the concave cavity, and the rest of which extends downward from the concave cavity. The outer side of the suction cup is in contact with the cavity wall of the concave cavity and has at least one positioning portion, each of which is used to be inserted into the positioning groove to position the suction cup; and

[0011] An inner core is arranged inside the suction cup to block the upper opening thereof and is used to press the suction cup against the cavity wall of the concave cavity; and

[0012] The outer cylinder and / or the inner core are used to carry the supported device. After the suction cup is pressurized, the portion thereof extending out of the concave cavity undergoes elastic deformation so as to be adsorbed on the supporting surface.

[0013] Optionally, each of the positioning grooves is an annular groove; and

[0014] Each of the positioning portions is an annular convex ridge to be embedded in the positioning groove.

[0015] Optionally, a sealing ring is provided between the inner core and the suction cup to seal a gap between the inner core and the suction cup.

[0016] Optionally, the top edge of the suction cup protrudes radially outward to form an annular positioning protrusion, and an annular embedding groove is formed on the inner side of the outer tube, and the positioning protrusion is embedded in the annular embedding groove to position the suction cup.

[0017] Optionally, a central through hole communicating with the concave cavity is formed on the upper portion of the outer cylinder; and

[0018] The upper portion of the inner core is embedded in the central through hole.

[0019] Optionally, the outer circumferential surface of the inner core includes a circumferential surface and a truncated cone surface from top to bottom, the truncated cone surface gradually extends radially outward from top to bottom, the circumferential surface is used to abut against the inner wall of the central through hole, and the truncated cone surface is used to abut against the inner side surface of the suction cup.

[0020] Optionally, the adsorption-type supporting device further includes: an elastic pad, which is arranged above the inner core and the outer cylinder and is firmly connected to the inner core and / or the outer cylinder, for supporting the supported equipment.

[0021] Optionally, an annular buffer groove is provided on the lower surface of the elastic pad to improve its buffering performance after being compressed.

[0022] Optionally, the annular buffer groove spans the upper surface of the outer cylinder and the upper surface of the inner core in the width direction.

[0023] Optionally, the adsorption type support device further comprises: bolts and nuts that cooperate with each other; and

[0024] The elastic pad is provided with a first countersunk hole for accommodating a nut, and the inner core is provided with a second countersunk hole for accommodating a bolt. The bolt is connected to the nut to achieve fastening connection between the inner core and the elastic pad.

[0025] Optionally, the bottom surface of the inner core is higher than the bottom surface of the outer tube, so that after the suction cup is adsorbed on the supporting surface, air remains between the inner core and the supporting surface.

[0026] The adsorption-type support device of the utility model is arranged between the supported equipment and the supporting surface to carry the supported equipment. After the adsorption-type support device is under pressure, the suction cup is pressed so that the part extending out of the concave cavity of the outer cylinder undergoes elastic deformation, and the gas in the space between it and the supporting surface is discharged, so that negative pressure is formed on the inner side of the suction cup, and it is adsorbed on the supporting surface. In this way, the position of the supported equipment is more stable, and the supported equipment will not fall over when it is impacted or hit. Moreover, since the suction cup is made of elastic material and is not rigidly connected to the supporting surface, it has a certain elastic buffering capacity and can absorb certain vibrations and impacts, which is beneficial to maintaining the stability of the supported equipment. In addition, if the adsorption-type support device is used to carry the supported equipment, there is no need to drill holes in the supporting surface, and the installation and disassembly are simple and convenient, which can effectively reduce the operation and maintenance costs.

[0027] Moreover, in the adsorption-type support device of the utility model, the suction cup and the outer cylinder are positioned by the positioning portion and the positioning groove. When the adsorption-type support device is subjected to lateral external force, no mutual misalignment and slippage will occur between the suction cup and the outer cylinder, thereby preventing the suction cup from twisting and causing air to enter the inside, causing the suction cup to detach from the support surface.

[0028] Furthermore, in the adsorption-type support device of the utility model, a sealing ring is provided between the inner core and the suction cup to seal the gap between the inner core and the suction cup, thereby avoiding air leakage and preventing air from entering the inner side of the suction cup and causing the suction cup to detach from the support surface.

[0029] Furthermore, in the adsorption-type support device of the utility model, an elastic pad is arranged above the inner core and the outer cylinder, and the supported device is supported by the elastic pad. Since the elastic pad has a certain elasticity and has the function of buffering the lateral external force, when the supported device is tilted by the external force, the suction cup can always be adsorbed on the ground. The annular buffer groove arranged in the elastic pad makes its buffering performance better.

[0030] Furthermore, in the adsorption support device of the utility model, the bottom surface of the inner core is higher than the bottom surface of the outer tube, so that after the suction cup is adsorbed on the support surface, air remains between the inner core and the support surface, thereby preventing the outer ring of the suction cup from tilting up due to excessive force at the center, thereby reducing the adsorption force.

[0045] The embodiment of the utility model provides an adsorption-type supporting device 10 . Figure 1 It is a schematic diagram of assembling an adsorption-type supporting device 10 and a supported device 20 according to an embodiment of the utility model.

[0046] like Figure 1 As shown, the adsorption-type support device 10 of the embodiment of the utility model is used to be arranged between the supported device 20 and a support surface D to carry the supported device 20. The supported device 20 can be equipped with one or more adsorption-type support devices 10. For example, three adsorption-type support devices 10 arranged in a triangle can be arranged, or four adsorption-type support devices 10 arranged in a square can be arranged. The support surface D can be the ground or the surface of other supporting objects. The number, specifications and arrangement of the adsorption-type support devices 10 can be reasonably configured according to the weight of the supported device 20 and the size of the support surface D to ensure that the supported device 20 is stably installed. Threaded fasteners or other fasteners can be used to fasten the supported device 20 and the adsorption-type support device 10. Alternatively, the supported device 20 can be directly pressed on the adsorption-type support device 10 without fastening.

[0047] Figure 2 is a structural schematic diagram of an adsorption-type support device 10 according to an embodiment of the utility model; Figure 3 Figure 2 An exploded schematic diagram of the adsorption-type support device 10 is shown; Figure 4 yes Figure 2 A schematic cross-sectional view of the adsorption-type support device 10 is shown; Figure 5 yes Figure 4 Schematic diagram of the decomposition.

[0048] like Figures 2 to 5 As shown, the adsorption-type supporting device 10 of the embodiment of the present invention may generally include an outer cylinder 300 , a suction cup 200 and an inner core 100 .

[0049] The bottom of the outer cylinder 300 is concave to form a truncated cone-shaped cavity 302 which tapers from bottom to top, and the cavity wall of the cavity 302 is provided with at least one positioning groove 320. The "truncated cone-shaped" cavity 302 here means that the cavity wall is a truncated cone surface 120 or a substantially truncated cone surface, and the truncated cone surface is a part of the cone surface of a cone.

[0050] The suction cup 200 is a truncated cone-shaped cylinder made of elastic material. The elastic material here refers to a material that is elastic and can be deformed when subjected to external force and can return to its original shape after the external force disappears, such as rubber. Part of the suction cup 200 is located in the cavity 302, and the rest of the suction cup 200 extends downward from the cavity 302. The outer side of the suction cup 200 is against the cavity wall of the cavity 302, and the suction cup 200 has at least one positioning portion 210, each positioning portion 210 is used to insert into the positioning groove 320 to position the suction cup 200, refer to Figure 4 .

[0051] The inner core 100 is arranged inside the suction cup 200 to block the upper opening thereof and is used to press the suction cup 200 against the cavity wall of the cavity 302. Thus, a closed airflow space S is formed between the bottom surface of the inner core 100, the inner side surface of the suction cup 200 and the support surface D. Figure 4 .

[0052] The outer cylinder 300 and / or the inner core 100 are used to carry the supported device 20, including three schemes: (1) The outer cylinder 300 carries the supported device 20, and the weight of the supported device 20 is borne by the outer cylinder 300. The inner core 100 needs to be fixed to the outer cylinder 300 so that the suction cup 200 is firmly located between the inner core 100 and the outer cylinder 300. (2) The inner core 100 carries the supported device 20, and the weight of the supported device 20 is borne by the inner core 100. The outer cylinder 300 needs to be fixed to the inner core 100 so that the suction cup 200 is firmly located between the inner core 100 and the outer cylinder 300. (3) The supported device 20 is carried by both the outer cylinder 300 and the inner core 100, and the weight of the supported device 20 is borne by both the outer cylinder 300 and the inner core 100. Figures 2 to 5The diagram shows a solution in which the outer cylinder 300 and the inner core 100 jointly support the supported device 20. The outer cylinder 300 and the inner core 100 may be made of a hard material, such as metal.

[0053] In this way, after the suction cup 200 is pressurized, the portion of the suction cup 200 extending out of the concave cavity 302 undergoes elastic deformation and is thus adsorbed to the support surface D. Specifically, the portion of the suction cup 200 extending out of the concave cavity 302 undergoes elastic deformation, so that most of the air in the airflow space S is squeezed out, and only a small amount of air is retained, so that the internal pressure of the airflow space S is lower than the external pressure, forming a negative pressure environment, so that the suction cup 200 is "adsorbed" on the support surface D.

[0054] The adsorption-type support device 10 of the embodiment of the utility model is arranged between the supported device 20 and the support surface D to carry the supported device 20. After the adsorption-type support device 10 is under pressure, the suction cup 200 is pressurized so that the part extending out of the concave cavity 302 of the outer cylinder 300 undergoes elastic deformation to discharge gas, so that negative pressure is formed inside the suction cup 200, thereby adsorbing to the support surface D. In this way, the position of the supported device 20 is more stable, and the supported device 20 will not fall over when it is impacted or hit. Moreover, since the suction cup 200 is made of elastic material and is not rigidly connected to the support surface D, it has a certain elastic buffering capacity and can absorb certain vibrations and impacts, which is conducive to maintaining the stability of the supported device 20. In addition, if the adsorption-type support device 10 is used to carry the supported device 20, there is no need to drill holes in the support surface D, and the installation and disassembly are simple and convenient, which can effectively reduce the operation and maintenance costs.

[0055] Moreover, in the adsorption-type support device 10 of the embodiment of the utility model, the suction cup 200 and the outer cylinder 300 are positioned by the positioning portion 210 and the positioning groove 320. When the adsorption-type support device 10 is subjected to lateral external force, no relative misalignment and slippage will occur between the suction cup 200 and the outer cylinder 300, thereby preventing the suction cup 200 from being twisted by force and causing air to enter the airflow space S, causing the suction cup 200 to detach from the support surface D.

[0056] In some embodiments, Figures 3 to 5 As shown, each positioning groove 320 is an annular groove. Each positioning portion 210 is an annular ridge to be embedded in the positioning groove 320. The annular ridge covers the entire circumference of the suction cup 200, has a stronger integrity, and has a stronger restraint ability on the suction cup 200. It is preferred that the cross-sectional shape of the positioning groove 320 is the same as the cross-sectional shape of the positioning portion 210, so that the positioning portion 210 is completely embedded in the positioning groove 320, forming a negative pressure adsorption effect, and making the relative position between the positioning portion 210 and the positioning groove 320 more stable. Of course, in some alternative embodiments, each positioning groove can also be made into a hole shape, and a plurality of positioning grooves can be provided, so that each positioning portion is in the shape of a convex point, and each positioning portion is inserted into a positioning groove.

[0057] In some embodiments, Figure 3and Figure 4 As shown, a sealing ring 500 is provided between the inner core 100 and the suction cup 200 to seal the gap between the inner core 100 and the suction cup 200, thereby preventing air leakage, keeping the airflow space S sealed, and preventing air from entering the inner side of the suction cup 200 and causing the suction cup 200 to separate from the support surface D. The sealing ring 500 can be made of rubber or other materials that are conducive to sealing. The inner core 100 and the suction cup 200 can be provided with annular grooves respectively to accommodate and constrain the sealing ring 500 to prevent the sealing ring 500 from being misplaced.

[0058] In some embodiments, Figures 3 to 5 As shown, the top edge of the suction cup 200 protrudes radially outward to form an annular positioning protrusion 230 , and an annular embedding groove 303 is formed on the inner side of the outer cylinder 300 , and the positioning protrusion 230 is embedded in the annular embedding groove 303 to position the suction cup 200 .

[0059] In some embodiments, Figure 4 and Figure 5 As shown, the upper portion of the outer cylinder 300 is provided with a central through hole 301 communicating with the concave cavity 302, and the upper portion of the inner core 100 is embedded in the central through hole 301. It is preferred that the upper outer peripheral surface of the inner core 100 and the inner hole wall of the central through hole 301 have the same shape so that they fit each other, so that the relative position between the outer cylinder 300 and the inner core 100 is more stable, thereby making the adsorption-type support device 10 more stable as a whole.

[0060] Furthermore, if Figure 4 and Figure 5 As shown, the outer circumference of the inner core 100 includes a circumferential surface 110 and a truncated cone surface 120 from top to bottom. The truncated cone surface 120 gradually extends radially outward from top to bottom. The circumferential surface 110 is used to abut against the inner wall of the central through hole 301, and the truncated cone surface 120 is used to abut against the inner side surface of the suction cup 200. This embodiment is configured so that the outer circumferential surface of the inner core 100 matches the shape of the central through hole 301 of the outer cylinder 300 and the inner side surface of the suction cup 200, so that the fit is tighter, making the suction support device 10 more stable as a whole.

[0061] In some embodiments, Figures 3 to 5 As shown, the adsorption-type support device 10 further includes an elastic pad 400. The elastic pad 400 is disposed above the inner core 100 and the outer cylinder 300, and is tightly connected to the inner core 100 and / or the outer cylinder 300, and is used to support the supported device 20. The elastic pad 400 can be detachably connected to the supported device 20 or directly support the supported device 20. The elastic pad 400 can be specifically made of a material having elastic buffering properties such as rubber.

[0062] Since the elastic pad 400 has a certain elasticity and can buffer the lateral external force, when the supported device 20 is tilted (tilted forward, backward, left or right) by the external force, the suction cup 200 can always be adsorbed on the ground. Furthermore, an annular buffer groove 430 can be provided on the lower surface of the elastic pad 400 to improve its buffering performance after being compressed. The annular buffer groove 430 can span the upper surface of the outer cylinder 300 and the upper surface of the inner core 100 in the width direction, so that the solid part of the elastic pad 400 can apply force more evenly to the upper surface of the outer cylinder 300 and the upper surface of the inner core 100, so that the force on both is more even, making the adsorption support device 10 more stable.

[0063] In some embodiments, Figure 4 As shown, the bottom surface of the inner core 100 can be made higher than the bottom surface of the outer tube 300, so that after the suction cup 200 is adsorbed on the support surface D, a small amount of air remains between the inner core 100 and the support surface D (i.e., the airflow space S), thereby preventing the outer ring of the suction cup 200 from tilting due to excessive force on the center, thereby reducing the adsorption force.

[0064] In some embodiments, Figures 3 to 5 As shown, the adsorption support device 10 also includes a bolt 610 and a nut 620 that cooperate with each other. The elastic pad 400 is provided with a first countersunk hole 410 to accommodate the nut 620, and the inner core 100 is provided with a second countersunk hole 113 to accommodate the bolt 610. The bolt 610 is connected to the nut 620 to achieve the connection and fastening of the inner core 100 and the elastic pad 400. Due to the provision of the first countersunk hole 410, the nut 620 is hidden in the first countersunk hole 410, does not protrude from the elastic pad 400, and does not interfere with the supported device 20. Due to the provision of the second countersunk hole 113, the head of the bolt 610 is hidden in the second countersunk hole 113, does not protrude from the bottom surface of the inner core 100, and does not hit the support surface D.

[0065] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
