mechanical structure

The punching-free base comprises a disc opening 1, a body 2, a flexible sealing gasket 3, a pressing plate 4, a spring 5, a pressing cap 6, uncured sealant 7, a sucking disc 8, a needle cylinder 9 and the like; coating a sealant in a buckle groove on the inner side of a disc opening 1, then embedding a body 2 flange into the groove, coating the sealant at the bottom of the cylinder flange end of the body 2, plugging a flexible sealing gasket 3 into the bottom of a cylinder and compacting the flexible sealing gasket 3 to enable the flexible sealing gasket 3 to be adhered with the bottom of the cylinder, placing a pressure plate 4 into the cylinder and pressing the pressure plate on the flexible sealing gasket 3, placing a spring 5 into the cylinder, wherein one end of the spring 5 is used for jacking the pressure plate 4, the other end of the spring 5 is jacked by a pressure cap 6, the pressure cap 6 is simultaneously screwed into the cylinder until the pressure cap 6 is flush with the outer surface of the body 2, the spring 5 is compressed, and the pressure of the spring enables the pressure plate 4 to tightly press the flexible sealing gasket 3; after the outer surface of the circular tube-shaped air suction opening at one end of the needle cylinder 9 is coated with sealant, the air suction opening is inserted into a hole reserved in the middle of the sucking disc 8; the uncured sealant 7 is independently vacuum-packed and kept in an uncured state so as to be smoothly extruded and filled when the punching base is installed; and the assembly of the punching-free base is completed.

Second, the working principle

After the punching-free base is assembled, when the punching-free base needs to be used, only a proper amount of uncured sealant 7 is required to be extruded to fill the deep groove of the adsorption surface of the disc port 1 and be higher than the adsorption surface of the disc port 1, then the adsorption surface of the disc port 1 is tightly attached to a fixed plane, so that the middle space of the disc port 1 is isolated from the outside air, the piston of the needle cylinder 9 is pushed to the air suction port end to completely empty the air in the inner cavity of the piston, the sucking disc 8 is tightly attached to cover the air cylinder pressing cap port of the body 2, the piston of the needle cylinder 9 is pulled to slide towards the position far away from the air suction port end at the moment, the space of the inner cavity of the needle cylinder 9 is larger and smaller, the air pressure in the inner cavity is lower, the sucking disc 8 completely covers the air cylinder pressing cap port of the body 2, so that the inner cavity of the needle cylinder 9 is only communicated with the air cylinder of the body 2 through the air suction port and the middle opening of the pressing cap 6, when the air pressure in the inner cavity of the needle cylinder 9 is reduced, the air in the air cylinder in the body 2 inevitably flows towards the inner cavity of the needle cylinder 9, namely, the air cylinder is continuously extracted along with the sliding towards the position far away from the air suction port end; meanwhile, the space air pressure on the two sides of the opening of the flange end of the cylinder of the body 2 is equal, namely the space air pressure in the middle of the disc opening 1 is equal to the space air pressure in the inner cavity of the cylinder, the pressing plate 4 tightly presses the flexible sealing gasket 3 under the pressure action of the compressed spring 5, namely the opening of the flange end of the cylinder is sealed, and the middle space of the disc opening 1 is isolated from the inner cavity of the cylinder; along with the sliding of the piston of the needle cylinder 9 far away from the air suction port end, the air in the air cylinder of the body 2 is continuously extracted, the air pressure in the air cylinder of the body 2 is continuously reduced, so that the air pressure difference of the space on two sides of the opening of the flange end of the air cylinder is increased more and more, the air pressure in the middle space of the disc port 1 is greater than the air pressure in the inner cavity of the air cylinder, the air pressure difference can generate a jacking force on the pressure plate 4 in a direction opposite to the pressure applied on the pressure plate 4 by the spring 5, when the jacking force is greater than the pressure applied on the pressure plate 4 by the spring 5, the pressure plate 4 is pushed to slide to the non-flange end of the air cylinder, namely the opening of the flange end of the air cylinder is opened, the process that the piston of the needle cylinder 9 is pulled to slide to the non-air suction port end is the process of continuously extracting air from the middle space of the disc port 1, the air pressure in the middle space of the disc port 1 is continuously reduced, the vacuum degree is gradually increased, and the holistic non-punching-free base obtains the increasing vacuum adsorption force and the bearing capacity; when the piston of the needle cylinder 9 is pumped to the farthest end far away from the air pumping opening, the piston stops sliding, the volume of the inner cavity of the needle cylinder 9 stops increasing, the air pressure in the cavity stops reducing, the air flow from the middle space of the disc opening 1 to the inner cavity of the needle cylinder 9 through the body 2 air cylinder can be rapidly stopped, namely the air pumping process from the middle space of the disc opening 1 is finished, at the moment, the air pressure in the three mutually communicated spaces is equal, namely the air pressure in the middle space of the disc opening 1, the air cylinder space of the body 2 and the air pressure in the inner cavity space of the needle cylinder 9 are equal, the pushing force acting on the pressing plate 4 originally due to the air pressure difference disappears, the pressing plate 4 slides to the flexible sealing gasket 3 again under the pressure of the spring 5 and is pressed, namely the opening at the flange end of the body 2 air cylinder is completely sealed again; the middle space of the disk port 1 of the punching-free base is completely sealed and has stable vacuum degree, and certain adsorption force and bearing force are formed; then the piston of the needle cylinder 9 can be pushed to slide to the air exhaust port end, the volume of the inner cavity of the needle cylinder 9 is reduced, so that the vacuum degrees in the inner cavity of the needle cylinder 9 and the cylinder of the body 2 are continuously reduced until the vacuum degrees disappear, and the sucking disc 8 and the needle cylinder 9 can be easily separated from the punching-free base body 2; when the piston of the needle cylinder 9 is pushed to the air suction port end, namely the needle cylinder 9 of the sucking disc 8 is peeled off from the body 2, because the opening of the flange end of the cylinder of the body 2 is sealed by the pressing plate 4, the middle space of the disc port 1 and the space of the cylinder of the body 2 are separated, along with the sliding of the piston of the needle cylinder 9 to the air suction port end, the vacuum degrees in the inner cavity of the needle cylinder 9 and the cylinder of the body 2 are gradually reduced, the air pressure is increased, and the air pressure and the vacuum degree in the middle space of the disc port 1 are maintained, so the air pressure difference can be generated in the space of the cylinder of the body 2 and the middle space of the disc port 1, the air pressure in the space of the cylinder of the body 2 is gradually larger than the air pressure in the middle space of the disc port 1, the top thrust generated on the pressing plate 4 has the same direction as the acting force of the spring 5, and the top thrust cannot cause the opening of the flange end of the cylinder of the body 2 to be opened and the pressing plate 4 to be pressed more tightly, namely the opening of the flange end of the cylinder of the body 2 is sealed more firmly; in order to ensure that the middle space of the disc opening 1 can obtain the highest vacuum degree, the operation process can be adopted to repeatedly pump the middle space of the disc opening 1 for multiple times, and the punching-free base can be put into use after the operation is finished and the sucking disc 8 and the needle cylinder 9 are removed; in the use process of the punching-free base, two places are usually possible to leak to cause vacuum failure, and the punching-free base loses self-adsorption capacity, namely a gap between an adsorption surface of a disc opening 1 and an external adsorbed surface and an opening of a flange end of a cylinder of a body 2; the punching-free base effectively solves the possible leakage problem in the two aspects through the specific structural design; the filling of the uncured sealant plugs the possible micropores between the adsorption surface of the disc opening 1 and the external adsorbed surface, the flexible sealing gasket 3 is additionally arranged between the bottom of the cylinder of the body 2 and the pressing plate 4, the direct hard contact between the bottom surface of the cylinder and the pressing plate 4 is changed into the soft contact with the elastic gasket, the possible fine gap when the bottom surface of the cylinder is in hard contact with the pressing plate 4 is eliminated, and the possible leakage at the opening of the flange end of the cylinder of the body 2 is avoided; furthermore, the pushing force which is formed by the air pressure difference on the pressing plate 4 and has the same direction as the pressure of the spring 5 realizes the secondary pushing of the pressing plate 4 under the condition that the spring 5 pushes the pressing plate 4 for the first time, so that the flexible sealing gasket 3 at the opening of the flange end of the cylinder of the body 2 is in closer contact with the pressing plate 4, and the opening of the flange end of the cylinder of the body 2 is ensured to be completely closed, therefore, the vacuum degree of the working space of the adsorption surface of the disc opening 1, which is necessary for the punching-free base to exert the use function, is easily obtained and can be maintained for a long time; due to the design of the plurality of deep grooves on the adsorption surface of the disc opening 1, uncured sealant cannot shift after being cured at room temperature, and the effectiveness and stability of gap sealing between the adsorption surface of the disc opening 1 and an external adsorbed surface are greatly improved; the hollow structural design in the middle of the pressing cap 6 is convenient for the sucking disc 8 needle cylinder 9 to suck air from the body 2 cylinder, and after the sucking disc 8 needle cylinder 9 is removed from the body 2, outside air can enter the body 2 cylinder through the middle hole of the pressing cap 6, so that huge air pressure difference is formed between two side spaces of the pressing plate 4, namely the middle space of the disc opening 1 and the space of the body 2 cylinder, and further strong pushing force to the pressing plate 4 in the same direction as the acting force of the spring 5 is generated, the opening of the flange end of the cylinder is more stably sealed, meanwhile, a proper amount of uncured sealant can be injected into the body 2 cylinder through the middle hole of the pressing cap 6 after the non-punching base is installed, after the sealant is cured, the flexible sealing gasket 3 is thoroughly isolated from contacting with the outside air, the rapid aging of the flexible sealing gasket is avoided, the service life of the non-punching base is prolonged, the long-term reliable sealing of the opening of the flange end of the body 2 cylinder is ensured, a new sealing structure except the pressing plate 4 of the flexible sealing gasket 3 is formed in the body 2 cylinder, and the sealing structure thoroughly seals the working space required by the non-punching base, namely the passage between the disc opening 1 and the outside, and the possibility of air leakage is eliminated; the 8 cylinder 9 of sucking disc can assemble together very conveniently and form the evacuation instrument, and this instrument only plays a role when exempting from the base installation of punching and does not need in its use, therefore 8 cylinders 9 of sucking disc and the separable structural design of the base body 2 of exempting from to punch have greatly reduced the structure complexity of the base self of exempting from to punch, have reduced the volume of the base self of exempting from to punch, also can be very convenient simultaneously to exempting from to punch the base and repeatedly bleed many times. Further, the utility model relates to a exempt from to punch base dish mouth 1 adsorption surface intermediate space and be workspace adoption large tracts of land low thickness design promptly, the air capacity that just also needs to take out under the same adsorption area condition drops to minimumly, this structural design just can realize obtaining higher vacuum under the condition that does not produce the influence to exempt from to punch base self through two kinds of ways together with the separable structural design of aforementioned 8 cylinder 9 of sucking disc and body 2, bigger adsorption affinity, the way is firstly to adopt as big as possible voluminous cylinder to improve cylinder intracavity volume and the volumetric ratio of dish mouth adsorption surface workspace promptly, make dish mouth adsorption surface workspace by the once vacuum that the extraction obtained of cylinder as high as possible, thereby the way is secondly to carry out the repetition to dish mouth 1 intermediate space through 8 cylinder 9 and bleed for a plurality of times and obtain higher vacuum, bigger adsorption affinity. If need shift reinstallation after the installation of external facilities equipment, then only need to prize open a set of mouth 1 with instruments such as blade and make and exempt from to punch the base and break away from the back with original adsorbed surface and reject the sealed glue of solidification in a set of mouth 1 adsorption surface deep trouth and the body 2 cylinder, then again according to aforementioned step flow install the operation can again.

The utility model has the advantages that: under the condition that no external equipment is arranged, the self-suction vacuum function of the punching-free base is realized through the cylinder sucker needle cylinder mechanism, namely the punching-free base can be fixed at a determined position without punching and positioning; under the condition of not increasing external sealing measures, the effective formation and continuous maintenance of the vacuum degree and suction force of the disc opening working space are realized without failure through the structural designs of filling uncured sealant, a body cylinder pressure plate spring and the like in a specific disc opening adsorption surface deep groove of the punching-free base; the punching-free base is provided with a plurality of long open grooves with different specifications and different directions, and the nut in the groove can translate but cannot rotate, so that the punching-free base is convenient for installing and fixing external facility equipment with different specifications; the overall appearance, the material, the shape, the size and the like of the punching-free base can be determined according to the application, the use environment, the required bearing capacity and the like; the punching-free base is simple in structure, wide in application range, low in cost and easy to realize.
