Abstract

Disclosed is an empty or oil-hydraulic cylinder magnetic induction switch which is provided in the plow groove of the empty or oil-hydraulic cylinder surface, comprising a body, a pedestal, a liner bushing and a regulating piece, wherein the regulating piece has a snail join section which is in a liner bushing tapping, and a perforation slide set section which is provided on the pedestal inwards protruding and extending from the snail join section. The slide set section is restricted to move in a finite distance of the perforation, which makes the regulating piece simultaneously drive the liner bushing to move outwards when the regulating piece rotates. The two projections of the liner bushing relatively support the two blocking sections of the plow groove outside adjacent to the empty or oil-hydraulic cylinder, so the magnetic induction switch is fixed in the plow groove. The magnetic induction switch has the broad applicability to different shape plow grooves.

Embodiment

At first as shown in Figure 4, the preferred embodiment of the utility model sky/oil hydraulic cylinder magnetic induction switch 1, this switch can be arranged on the microscler groove 21 interior specific places on sky/oil hydraulic cylinder 2 surfaces, obtains good magnetic induction effect with the magnetic position that cooperates sky/oil hydraulic cylinder 2 internal pistons.

As shown in Figs. 4-6, sky/oil hydraulic cylinder 2 is provided with along it and extends axially and a corresponding circular-arc diapire 22 that is positioned at groove 21 bottoms, reach from diapire 22 and extend and the two side 23 of respective grooves 21 Widths two opposition sides, and groove 21 extends to an end of sky/oil hydraulic cylinder 2 and forms an opening 24.Two side 23 protrudes out a stop section 25 in opposite directions away from the outer rim place of diapire 22.Each stop section 25 comprises a vertical edges 251 and a hypotenuse 252 same linearly and that be connected in the present embodiment.In addition, " sky/oil hydraulic cylinder " speech means it and can be air compressing cylinder or oil hydraulic cylinder in this specification, and just the actuating fluid of cylinder interior can be any suitable gas or liquid.

Magnetic induction switch 1 comprises a body 3, a base 4, a lining 5 and an adjustment part 6.Body 3 has an elongated housing 31, and some electronic components that are contained in housing 31 inside, and housing 31 vertical ends are electrically connected to corresponding power supply and control circuit place by lead 32.Housing 31 comprises in order to be the first circular-arc inwall 311 together against sky/oil hydraulic cylinder 2 grooves, 21 diapires 22, to be positioned at opposition side and to be first outer wall 312 on plane with first inwall 311, and two the first side walls 313 that is positioned at first inwall and 311,312 symmetries of outer wall, the height of housing 31 is slightly less than the degree of depth of groove 21 in the present embodiment.

Base 4 vertically protrudes out near an end of groove 21 openings 24 from body 3, and it comprises circular-arc second inwall 41 that continues and extend from first inwall 311, reaches from first outer wall 312 the second plane outer wall 42 towards sunken inside.Base 4 is radially offered a circular perforations 43 along body, and perforation 43 is borrowed the change of diameter in the middle section and formed first and arrest limit portion 44.

Lining 5 is the sides nut shape, one plane the 3rd inwall 51 that connects to base 4 second outer walls 42 is arranged on it, and the respective grooves two side 23 that stretches out from the 3rd inwall 51 both sides oppositely is circular-arc two protuberances 52 that protrude out, and lining 5 centers are provided with tapped screw 53.

Adjustment part 6 is cylindric, which is provided with that a screwing section 61 and a self-screwing section 61 inwardly protrude out and diameter slightly reduces to pass the sliding section 62 of base 4 perforation 43.Screwing section 61 outer rims are arranged with word fluting 611, and sliding section 62 is located diameter near the inner and slightly protruded out, and arrest limit portion 44 produces position-limiting action to pulling the second inflexible limit portion 621 to form with first of base 4.Arrest limit portion 44 and second by means of first and arrest matching of limit portion 621, reach the inner edge 612 of screwing section 61 and mutual the supporting of base 4 second outer walls 42 corresponding positions and pull, make adjustment part 6 be limited in the interior activity of specific range of perforation 43.

Shown in Fig. 5 and 6, at first magnetic induction switch 1 is inserted in the grooves 21 behind the ad-hoc location from groove 21 1 end openings 24 of sky/oil hydraulic cylinder 2, borrow fluting 611 that bottle opener or other instruments force in adjustment part 6 turn adjustment part 6 in a clockwise direction, because it is interior movable that aforementioned adjustment part 6 is limited in the specific range of perforation 43, and because the effect that screws togather of lining 5 and screwing section 61, lining 5 is outwards moved gradually from Fig. 5 position, be resisted against 25 hypotenuses, 252 inboards, two stop sections of sky/oil hydraulic cylinder 2 grooves 21 until 5 liang of protuberance 52 outsides of lining as shown in Figure 6, whereby magnetic induction switch 1 closely and firmly is fixed on groove 21 inside, and in the above-mentioned adjustment part 6 turn processes, magnetic induction switch 1 arbitrary end can not occur as in as the existing design outwardly the inclination situation take place, so can guarantee the accuracy of its magnetic induction running.

Another obvious advantage of the present utility model is that it can be used for the sky of difformity size/oil hydraulic cylinder groove, and has wider adaptability.In the Another Application example shown in Fig. 7 and 8, sky/oil hydraulic cylinder 2 grooves 210 have significant difference with groove 21 geomeries of aforementioned first embodiment, also there is variation in shape two stop sections 250 and groove 21 stop sections 25 of groove 210, and the height of magnetic induction switch 1 housing 31 is approximately identical to groove 210 degree of depth.In the present embodiment, the identical magnetic induction switch 1 of first embodiment can be provided with and be fixed in the groove 210 equally, its difference is adjustment part 6 turns adjustment distance difference in two embodiment only.

In the application examples again shown in Fig. 9 and 10, when groove 211 size shapes and aforementioned groove 21,210 differences are excessive, only need the lining 50 of displacement different size shape, and need not be with adjustment part 6 even whole group magnetic induction switch 1 integral replacing, so have cost-effective effect concurrently
