Description
Technical field
the utility model belongs to machinery manufacturing technology field, relates to a kind of connecting device.
Background technology
The workshop of
manufacturing enterprise generally is to adopt the station car to transport required parts, moves the working position apparatus car through tractor truck.The rear haulage device of tractor truck and working position apparatus car is to be made up of outer, top, outer, bottom and lock pin; On outer, top and the outer, bottom cooresponding through hole is arranged, during connection, between the protraction headgear insertion outer, top and outer, bottom with the station car; Again lock pin is penetrated through hole, accomplish connection.In the working process, workman's long-time continuous bends over to operate, inconvenience, and labour intensity is big, and inefficiency is prone to take place injury accident.
The utility model content
The technical matters that
the utility model will solve provides a kind of performance safety, easy to operate and can be recessed in the working position apparatus and do not influence the quick rear haulage device of working position apparatus of station ability to speak car functions of use.
the utility model comprises lock pin, outer, top and outer, bottom, and there is bottom cavity at the below and the rear of outer, bottom, and the joist of level is installed on the bottom cavity; On the bottom cavity of joist below horizontal pedal drive shaft is housed, the pedal drive shaft outside is equipped with opens pedal, and transmission arm is installed on the pedal drive shaft; Transmission arm is made up of forearm, postbrachium and following locking block, and following locking block top rear side has block, is wound with the rising torsion spring on the pedal drive shaft; Horizontal anchor shaft is housed on the bottom cavity between joist and the pedal drive shaft, reverse locating device is installed on the anchor shaft, reverse locating device is made up of last locking block and linked block; Last locking block is corresponding with following locking block apical position, and anchor shaft is wound with the interlock reduction torsion spring, has the slot of fore-and-aft direction on the joist front end middle; The both sides at joist rear portion have pilot hole; The staged percussion fuze is installed above the joist, and staged percussion fuze trailing flank is topped bar and is got out of a predicament or an embarrassing situation, and the retracing spring of horizontal fore-and-aft direction is housed between bottom of getting out of a predicament or an embarrassing situation and the bottom cavity; Guide groove is arranged at the bottom of staged percussion fuze; The slot that the linked block of reverse locating device passes joist gets in the guide groove, and the fuse locking block is arranged between the bottom cavity at staged percussion fuze and its rear portion, and fuse locking block both sides are connected with downward guidepost respectively; Guidepost passes pilot hole, and the bottom is corresponding with the postbrachium position of transmission arm.When being connected between station car and tractor truck and station car and the station car, the protraction headgear of station car inserts between the outer, top and outer, bottom of rear haulage device, bump staged percussion fuze; The staged percussion fuze moves backward, and the guide groove edge drives linked block, and reverse locating device is rotated counterclockwise; Last locking block breaks away from following locking block, and pedal drive shaft rotates counterclockwise under the effect of rising torsion spring, and the forearm through transmission arm makes the lock pin rise; The locking protraction headgear, simultaneously, the fuse locking block combines with topping bar of staged percussion fuze; Because the tension force effect of retracing spring, the staged percussion fuze moves forward, and the fuse locking block breaks away from tops bar; This moment, the postbrachium of transmission arm moved down, and fuse locking block and guidepost free fall are on the fuse locking block drops on and gets out of a predicament or an embarrassing situation; Block the staged percussion fuze; Make the fuse locking block pin the staged percussion fuze securely, thereby guarantee to cross when protraction headgear bump staged percussion fuze situation takes place in the journey in tractor truck and station garage, the staged percussion fuze is in the lock state.When the protraction headgear of station car need break away from the rear haulage device; Trample downwards and open pedal, pedal drive shaft overcomes and rises the torsion spring application force and clockwise rotate, and lock pin falls; Rear wall holds up guidepost; The fuse locking block rises to leave and gets out of a predicament or an embarrassing situation, and simultaneously, last locking block combines with following locking block at the locking block return that makes as the time spent of interlock reduction torsion spring.
Strong magnet is equipped with in
on the outer, top, lock pin is an iron material.After lock pin rose the locking protraction headgear, if the rising torsion spring lost efficacy, lock pin still can lock protraction headgear because strong magnet attracts, and trample open pedal after, do not influence lock pin and break away from the rear haulage device.
the utility model is easy to operate, quick, can effectively reduce labour intensity, increases work efficiency, and performance is safe and reliable.
