Embodiment one
A kind of anti-static system that the utility model embodiment provides, be arranged on the top of oil storage tank, for eliminating sampling/tester electrostatic with it, as shown in Figure 1, this anti-static system comprises touch unit and magnetic force fixed device, and each parts of touch unit and magnetic force fixed device are conductor; Touch unit is made up of base, vertical rod 4 and touch ball 5, and touch the top that ball 5 is connected to vertical rod 4, the bottom of vertical rod 4 is connected with base; Magnetic force fixed device 1 is for being connected to fixing base 3 by be fixed 2, and to be fixed 2 i.e. above-mentioned base, fixing base 3 i.e. above-mentioned oil storage tank, and touch unit is connected to the abhiseca of oil storage tank by magnetic force fixed device 1.
Again in conjunction with shown in 2, this magnetic force fixed device comprises magnetic force assembly 12 and connector 11; Magnetic force assembly 12 can be magnet, magnetic force rubber etc., and be arranged between to be fixed 2 and fixing base 3, magnetic force assembly 12 is connected with fixing base 3 magnetic force; Magnetic force assembly 12 is provided with counterbore near the side of fixing base 3, and counterbore is substantially stepped, and run through magnetic force assembly 12, to be fixed 2 is provided with the hole relative with counterbore position, and the hole on to be fixed 2 is through hole; One end of connector 11 is successively through above-mentioned counterbore and hole, and connector 11 is undertaken spacing with to be fixed 2 by axial limiting pair; The other end of connector 11 is provided with countersunk head, countersunk head is used for coordinating with counterbore forming clamping, and connector 11 can be sunk screw, and the end face of countersunk head has the groove for inserting screwdriver, countersunk head can entirety sink in counterbore, does not affect the planarization of magnetic force assembly 12 bottom surface.
Above-mentioned magnetic force fixed device 1 also comprises nut 13, connector 11 punched out, and one end of connector 11 punched out is provided with external screw thread, and above-mentioned axial limiting is secondary coordinates formed screw thread pair with the external screw thread of connector 11 for nut 13; Being provided with horizontal washer 14 between nut 13 and to be fixed 2, for reducing end wear, also can enclosing by sandwiched spring pad 15, make, between nut 13 and to be fixed 2, there is elastic compensating, ensure that fastening quality.
Certainly hole can also be made to be provided with internal thread, then in conjunction with shown in 3, the one end making connector 11 be inserted in hole is provided with external screw thread, above-mentioned axial limiting pair is then the screw thread pair that the external screw thread of connector 11 and the screw-internal thread fit in hole are formed.Be understandable that, axial limiting pair can be one of above-mentioned two kinds of modes, also can be other forms, as long as the top of restriction connector 11 is return from the hole of to be fixed 2.
Be preferably circular or regular polygon for be fixed 2, its geometry external diameter is more than the twice of the diameter touching ball 5, and vertical rod 4 is connected to the geometric center of to be fixed 2, is formed thus and supports stably; To be fixed 2 arranges multiple hole, the non-colinear arrangement of multiple holes, multiple hole is preferably evenly arranged in the edge of to be fixed 2 ringwise, and magnetic force fixed device 1 is many group of arranging corresponding to multiple hole, thus treat fixture 2 and form multi-point support, support effect is more stable; Due to magnetic force assembly 12 distribution in fallaway type, therefore relatively can reduce the area that lands of single magnetic force assembly 12, overcome the problem of the poor stability that oil storage tank deck brings due to out-of-flatness to a certain extent.
Be provided with for be fixed 2 and preferably arrange three holes, three hole non-colinear arrangements, being preferably is the edge that equilateral triangle is distributed in be fixed 2, and magnetic force fixed device 1 is and three corresponding three groups of arranging in hole; Due to three groups of magnetic force fixed devices 1 arrangement in equilateral triangle, each magnetic force fixed device 1 is an impetus, avoids because the phenomenon that certain magnetic force assembly 12 is unsettled appears in surface of oil storage tank out-of-flatness, anti-static system can not be shaken.
This anti-static system is connected with oil storage tank by magnetic force, stable connection, safety, without the need to being bolted or welding, can install in the later stage on oil storage tank in use, and this apparatus structure is simple, and body is easy to assembly, installs and also facilitate during use.
Embodiment two
The structure of a kind of anti-static system of the present embodiment two is substantially identical with embodiment one, and something in common repeats no more, and difference is:
As shown in Figure 4, to be fixed 2 is arranged three holes, three hole non-colinear arrangements, magnetic force fixed devices 1 are and three corresponding three groups of arranging in hole, between to be fixed 2 and magnetic force assembly 12, there is gap, connector 11 is divided into upper and lower two parts, upper and lower two parts connector 11 is connected by universal ball end 6, the gap location of universal ball end 6 between to be fixed 2 and magnetic force assembly 12; Universal ball end 6 comprises multi-directional ball 62 and ball seat 61, the a part of connector 11 being plugged in hole is connected with ball seat 61, the a part of connector 11 being plugged in counterbore is connected with multi-directional ball 62, the diameter of ball seat 61 is greater than the diameter in hole and is less than or equal to the diameter of counterbore, make ball seat 61 can through counterbore and cannot passing hole, axial limiting again between the first half of fit connection 11 and to be fixed 2, to make between the first half of connector 11 and to be fixed 2 row to fixing; Can be threaded engagement between the latter half connector 11 and counterbore, make the latter half connector 11 relative with magnetic force assembly 12 fixing.
Thus, relative angle between each magnetic force assembly 12 and to be fixed 2 all can freely change, the landform that each magnetic force assembly 12 can touch according to it and adjust angle accordingly, therefore, the area of single magnetic force assembly 12 can arrange relatively large, makes it have larger magnetic force; And on the whole, three groups of magnetic force fixed devices 1 restrict mutually, the entirety of to be fixed 2 can not swing relative to fixing base 3, and the vertical rod 4 of above enclosing and touch ball 5 also can not shake.
During concrete use, no matter this anti-static system is placed on any position of oil storage tank abhiseca, each magnetic force assembly 12 all can according to touched landform corresponding automatic adjustment angle, can accomplish each magnetic force assembly 12 all with fixing base 3 close contact, the magnetic force of each magnetic force assembly 12 is played to maximum; On the whole, three impetus of this anti-static system all with fixing base 3 close contact, and mutually to restrict between three impetus, make to be fixed 2 not swing relative to fixing base 3, the arrangement of single unit system is not only firmly but also steady.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection range of the present utility model.
