Abstract
The utility model relates to a novel road blocking device, particularly a traffic control system of road vehicles. The utility model is composed of a motor, a connecting rod, a rotating shaft, a blocking rod, etc. The utility model is characterized in that the motor is fixedly connected with a pinion which is engaged with a gearwheel; a screw rod is fixedly connected to the gearwheel; the screw rod is connected with a nut push rod in a screw thread connection mode; the nut push rod is connected with the connecting rod; the connecting rod and the blocking rod are respectively fixed on the rotating shaft. The utility model has the advantages of simple structure, compact structure, high positioning accuracy rate, reliable work and low manufacture cost. The utility model is suitable to be used in traffic control crossings and gates of institutions and enterprises.
Description
A kind of novel road keeps off, and relates to the traffic control system of road vehicle.
Each traffic road junction, machine-operated enterprise door path retaining adopt slide fastener or weight connecting rods more at present, structure heaviness, operation inconvenience.In recent years, along with Freeway Development, the automatically controlled road of Crank link type retaining has been adopted at many road junctions, gives people's letter joint, lucid and lively sensation.But in use, also there are many problems in this mechanism, and is inaccurate as the control position, frequent generation misoperation out of control and burn motor etc., and in addition, because this mechanism need use multiple deceleration device, manufacturing cost is higher.
The purpose of this utility model is for avoiding above-mentioned deficiency, a kind of novel road retaining being provided
The purpose of this utility model is achieved in that a kind of push rod road retaining of being made up of motor, connecting rod, rotating shaft, pin etc., it is characterized in that: motor is fixedlyed connected with pinion, pinion and gear wheel engagement, fixedly connected screw rod on gear wheel, screw rod is threaded with the nut push rod, the nut push rod connects connecting rod, and connecting rod and pin are separately fixed in the rotating shaft.
The utility model has the advantages that because the employing screw mechanism is realized slowing down and changing the direction of motion, simple in structure, compact, the accuracy rate that puts in place height, reliable operation, low cost of manufacture are suitable for the traffic road junction and machine-operated enterprise gate uses.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model structural representation.
The utility model is by motor 9, connecting rod 3, rotating shaft 2, pin 1 parts such as grade are formed, motor 9 and 8 strong connections of pinion, pinion 8 and gear wheel 7 engagements, screw rod 6 is connected with gear 7 keys, screw rod 6 is connected with nut push rod 4 spiral shell mosquitos, its outer cover 5 that is provided with, nut push rod 4 flexibly connects with connecting rod 3, connecting rod 3 and pin 1 are separately fixed in the rotating shaft 2, during work, motor 9 driven gears 8 rotate also to drive with its meshed gears 7 and rotate, and screw rod 6 and gear 7 rotate with speed and also can drive nut push rod 4 and prolong the axial direction reciprocating motion like this, nut push rod 4 drives rotating shaft 2 by connecting rod 3 and rotates, and last rotating shaft 2 drives pin 1 swing.Pin 1 can be in the reciprocal lifting of horizontal level or upright position.Operating personnel can realize the purpose of keeping off a car or putting car by control button.
