Abstract
The utility model relates to the technical field of medical apparatuses and instruments, in particular to a novel torque handle. According to the novel torque handle, a single direction thrust ball bearing is arranged at the front end, connected with an outer sleeve, of a clutch fixing shaft, the clutch fixing shaft is sleeved with a clutch, a flat key is arranged on the clutch, the clutch fixing shaft is sleeved with a belleville spring, second O-rings are arranged on the two sides of the clutch fixing shaft, an adjusting nut and a first O-ring are arranged on the clutch fixing shaft, the clutch fixing shaft is further provided with a deep groove ball bearing with a dust cap, the deep groove ball bearing is arranged in the adjusting nut, and steel balls are arranged at the front end of the outer sleeve. The handle holding part of the novel torque handle is suitable for the size of the hand of a middle-aged man, and can provided rotating torque smoothly, the O-ring arranged on the tail part of the novel torque handle enables the novel torque handle to be good in sealing performance, and low speed running-in is carried out for more than 200 times to guarantee the fact that torque is between 2.8Nm to 3.2Nm after assembling.
Description
Technical field
The utility model relates to a kind of handle, relates in particular to a kind of novel torque handle.
Background technology
In prior art, medical field is often used torque handle, and torque handle after most importantly performance indications are used repeatedly torsion deviation can or can not occur, can or can not lose efficacy, this is the index that we weigh a torque handle quality.The torque range of existing torque handle is little, can't meet the need of market.
Summary of the invention
The technical problems to be solved in the utility model is: the torque range of existing torque handle is little, can't meet the need of market, and a kind of torque handle is provided.
in order to overcome the defect that exists in background technology, the technical scheme that its technical problem that solves the utility model adopts is: this torque handle comprises outer tube, the front end sleeve of outer tube is provided with slip cap, be provided with the clutch fixed axis in outer tube, be provided with spring between described outer tube and slip cap, the front end of described clutch fixed axis outer sleeve for connecting is provided with single direction thrust ball bearing, the outer sheathed clutch of described clutch fixed axis, clutch is provided with flat key, described clutch fixed axis is arranged with butterfly spring outward, and both sides are provided with O type circle two, described clutch fixed axis is provided with adjusting nut, and be provided with O type circle one, also be provided with the deep groove ball bearing with dust cap on described clutch fixed axis, deep groove ball bearing is placed in adjusting nut, the front end of outer tube is provided with steel ball.
According to another embodiment of the invention, the junction that further comprises described outer tube and slip cap is provided be used to the circumference extruding reducing of blocking location.
The beneficial effects of the utility model are: the handle grip part of this torque handle, can meet middle aged man's hand shape size, and can provide smoothly rotary torsion, afterbody uses O type circle to make its favorable sealing property, and hanging down goes round and round a millstone closes and is no less than 200 times, guarantees to assemble rear moment of torsion 2.8-3.2N.m.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
