Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, a kind of two worm gears, the spacing control structure of double contact switch by its uniqueness are provided, and make it have pair spacing control switchs automatically of advantage such as rational in infrastructure, that control is sensitive, spacing control is adjustable, stroke range easy to install and use and controlled is big.
The technical solution of the utility model is achieved in that
Automatic two spacing control switchs described in the utility model, be characterized in comprising shell body, transmission device, adjusting device and be installed on two in the described shell body overlapping contact switchs, wherein said transmission device comprises worm shaft, be arranged at two worm screws on this worm shaft and cooperate two tape spool worm gears of transmission with each worm screw, and equal coaxial device has the cam that can match with described contact switch on each tape spool worm gear, and an end of described worm shaft is provided with travelling gear.
For making the utility model structure more reliable, and can realize the accurate location of stroke, above-mentioned tape spool worm gear is provided with the fixed head that prevents its axial motion, supporting two movable regulating plates on this fixed head, above-mentioned two contact switchs are installed in respectively on two adjustable plates, and an end of each adjustable plate is provided with extension spring, and the other end is provided with the column screw that is used for locating adjustable plate, above-mentioned two contact switchs can move and move along with adjustable plate, with the accurate location by its forward and backward mobile realization stroke.
Its spacing control is more accurate in use in order to make the utility model, and above-mentioned shell body is provided with the nut that can be used for finely tuning the lateral adjustments screw of adjustable plate position and be used for fixing and lock this set screw.
For making the utility model can realize dual disconnection effect, two projections on above-mentioned two cams are used for disconnecting respectively two contact switchs 3 ° of radial missings, thereby realize dual disconnection effect, use on rolling screen door, can play the overwinding-proof effect.
The utility model is owing to adopted by two worm gears of uniqueness with the coaxial double cam of worm gear and reached the spacing control structure that the double contact switch that matches with cam etc. is formed, make the utility model in use, not only can rotate and drive the rotation of two worm gears by worm shaft, thereby realize the large velocity ratio transmission, increase stroke distances effectively, and two cams of two coaxial settings on the worm gear, make when worm gear rotates, the projection circumference that drives on the cam rotates, the bossing of projection rushes open contact switch, thereby realizes the switching effect of switch.And because the distance of its stroke can be controlled by the position of adjustment cam and contact switch, make it have advantages such as rational in infrastructure, easy and simple to handle, accurate positioning, controlled stroke range be big, thereby at the operating difficulties that has overcome prior art with imitating, technical barriers such as positioning accuracy difference, can be widely used in electric rolling gate door, elevator etc. need carry out automatic control equipment to the dealing stroke, is a kind of desirable travel control switch.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, automatic two spacing control switchs of the present utility model, comprise shell body 5, transmission device, adjusting device and be installed on two cover contact switchs 15 in the described shell body 5, wherein said transmission device comprises worm shaft 1, two worm screws that are arranged on this worm shaft 1 reach the two tape spool worm gears 9 that cooperate transmission with each worm screw, and equal coaxial device has the cam 10 that can match with described contact switch 15 and realize spacing coarse adjustment on each tape spool worm gear 9, cooperate by gear between the two, one end of described worm shaft 1 is provided with travelling gear 2, matches with the actuating unit of controlled device by this travelling gear 2.Make the utility model in use, can drive worm shaft 1 motion, rotate by worm shaft 1 again and drive 9 rotations of two tape spool worm gears, thereby realize the large velocity ratio transmission, increase stroke distances effectively by actuating unit.Two cams 10 of coaxial setting on the two tape spool worm gears 9, make when worm-wheel shaft rotates, the projection circumference that drives on the cam 10 rotates, the bossing of projection rushes open contact switch 15, thereby realize the switching effect of switch, so advantage such as that it has is rational in infrastructure, easy and simple to handle, accurate positioning, controlled stroke range are big.For making its adjusting more convenient, be provided with spring 11 in the above-mentioned cam 10, and, make cam 10 and tape spool worm gear 9 be in mated condition all the time, also convenient spacing coarse adjustment by jump ring 12 location.For making the utility model structure more reliable, and can realize the accurate location of stroke, above-mentioned tape spool worm gear 9 is provided with the fixed head 4 that prevents its axial motion, supporting two movable regulating plates 3 on this fixed head 4, and above-mentioned two contact switchs 15 are installed in respectively on two adjustable plates 3.Two contact switchs 15 can move along with moving of adjustable plate 3 during use, with the accurate location by its forward and backward mobile realization stroke.(in Fig. 1,, can't see in the drawings, so the label 9 of tape spool worm gear just can only be marked on its position because two worm gears in the utility model have been blocked by shell body 5, fixed head 4 and cam etc.) and an end of above-mentioned adjustable plate 3 be provided with extension spring 14, the other end is provided with the column screw 8 that is used for locating adjustable plate 3.Two projections on above-mentioned two cams 10 its objective is to be used for disconnecting respectively two contact switchs 3 ° of radial missings, thereby realize dual disconnection effect.On rolling screen door, use, play the overwinding-proof effect.Its spacing control is more accurate in use in order to make the utility model, and above-mentioned shell body 5 is provided with the nut 6 that can be used for finely tuning the lateral adjustments screw 7 of adjustable plate 3 positions and be used for fixing and lock this set screw 7.We can say that also the adjusting device in the utility model is made up of two parts: 1. 2. fine adjustment of coarse adjustment.Coarse adjustment is finished by the coaxial cam 10 of worm gear, and fine adjustment is finished by the set screw 7 of shell body 5 sides.The utility model is in the process of using, its two covers contact switch 15 can control the coming of controlled device respectively, toward the startup of stroke with stop, the distance of its stroke can save cam 10 by adjuster and control with the spacing position of contact switch 15, so have rational in infrastructure, control is sensitive, spacing control is adjustable, the advantage of easy to install and use and controlled stroke range, can be widely used in electric rolling gate door, elevator etc. need carry out on the automatic control equipment the dealing stroke.
