The utility model content
The utility model technical issues that need to address provide a kind of powerful spiral strainer, it mainly is to solve the path increment that the existing in prior technology strainer can not effectively be controlled the user, only be prompting operation person with the warning line, product was in use lost efficacy, when in reality is used, requiring the large-tonnage operation, can't satisfy the technical problem of engineering actual demand etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Powerful spiral strainer of the present utility model, comprise body, body is provided with cross-drilled hole, the cross-drilled hole place that it is characterized in that described body is provided with shakes the hand, shaking the hand is provided with push rod, and push rod is connected with ratchet, and cross-under has conical tooth shaft in the cross-drilled hole, be connected with on the conical tooth shaft can with the ratchet of ratchet interlock, conical tooth shaft the inner is engaged with bevel gear; Be provided with screw mandrel in the body, wire rod thread is connected on the end face of bevel gear, and screw mandrel the inner is socketed in the inside of guide connecting rod, and the outer end is connected with the extension arm, and cross-under has bearing pin on the extension arm; The end of screw mandrel the inner is connected with back-up ring by jump ring, and the outer end of guide connecting rod is connected with hook.Range of the present utility model is 200MM, and maximum tightening force can be increased to 32T.Body can separately be made by body A, body B, and it can adopt height 40GR hot investment casting part, and the anti-position undercapacity that not only efficiently solves conventional cast spare causes body breakage problem in use, and makes the bright and clean sharp outline of outward appearance.Back-up ring can play spacing effect, and screw mandrel and bevel gear come off in preventing to use.Push rod has played the effect of clutch, and when not working, ratchet on the push rod and ratchet are thrown off, and can't drive conical tooth shaft after the rotation of shaking the hand and rotate, and can only dally.During work, promote push rod downwards, the tooth interlock of the ratchet of push rod and ratchet, at this moment rotating shakes the hand can drive the conical tooth shaft rotation.
As preferably, have a plurality of shrinkage pools on the described push rod, be connected with spring in shaking the hand, spring is connected with the steel ball that can embed in the shrinkage pool.Two grades of ratchets can be arranged on the push rod, and shrinkage pool quantity can be corresponding two, is convenient to the just commentaries on classics and the counter-rotating of conical tooth shaft, makes the normal convergent-divergent of strainer.
As preferably, be provided with thrust ball bearing between described bevel gear and the body, make things convenient for the rotation of bevel gear.
As preferably, the cross-drilled hole place of described body is connected with dust cap, and ratchet places in the dust cap.
Therefore, the utlity model has in main shaft screw mandrel rear end has increased back-up ring, jump ring structure, and screw mandrel comes off with bevel gear and separates the product failure problem that causes in preventing to use, and has increased range and tightening force, satisfied the engineering actual demand, characteristics such as simple and reasonable for structure.
