CN2504039Y - High torque combined reverse ratchet spanner - Google Patents

Abstract

The utility model discloses a high-torque compound turning thorn gear spanner, wherein, a direction controller in a compound turning controlling device directly combines with an elastic component and a stopping component into a whole to stop a stopper in a stopping groove of the spanner, so that the stopping part, at which the stopper stops towards a driving component, can be controlled; a forced stopping occurs between the stopper and the stopping wall of the stopping groove; the stopping part of a turning stopper can be designed into a stopping part with opposite arc sides on two sides and a surface of blocking side is kept in the middle of the stopping part, thereby increasing the combining stopping effect to a driving body, and reducing the interfering cooperation when controlling the turning.

Description

A kind of combined type reversing ratchet wrench of high torsion

The utility model relates to the combined type reversing ratchet wrench of high torsion.

The commutation retainer of applying for a patent in the past is that Yu Erduan is symmetrical structure, one side is the top on the little arc of the indent plane groove of pulling, the limit also is an arcwall face in addition, but retainer with many straight sawtooth stratum, and every layer of blocking limit is flat face, make it to be resisted against in the retainer groove of actuator, but its structure on using and make, reality finds that the following points deficiency is arranged:

1, blocking is interfered easily: the straight square blocking limit of retainer of its commutation retainer, its retainer is tied to form a form that pivots, must there be clearance to produce, can't keep moving on the plane when therefore pivoting, the inevitable phenomenon that produces angle end blocking mutually in the tip of retainer, not only cause the injury of blocking angle end, easilier cause unnecessary interference, feasible effectively blocking stop, promptly can cause the situation of poor stops such as slippage, more can be owing to bad contact causes two destruction or wearing and tearing between retainer.

2, fitness is not good: between two retainers because effectively stop braking, so when using hand-held tool, the actuator of installing is placed on the bolt that needs to rotate in the drive division, the effectively combination of its fitness, so that the trouble in the formation use.

The purpose of this utility model provides a kind of combined type reversing ratchet wrench of high torsion, and this ratchet spanner not only can increase the sealing property that is fastened, and more can effectively reduce the interference situation.

The technical solution of the utility model is: a kind of combined type reversing ratchet wrench of high torsion, this spanner has lever, handle end enlarges and forms drive division, drive division central authorities are provided with the driving room of the ccontaining actuator of confession that runs through, in driving the locking groove that the nearly grip of room is provided with an opening form in addition, it is characterized in that:

The end of locking groove centre is provided with a ringent element containing groove, pulls between part and commutation retainer be arranged in direction control piece, flexible member, the top of forming direction-control apparatus;

Described element containing groove and locking groove are the state that joins; Retainer is placed in the locking groove, and the direction control piece is arranged in the element containing groove, is provided with flexible member and the top part of pulling between direction control piece and retainer in addition and holds mutually, and the top part of pulling is extend out between locking groove and element containing groove by the direction control piece; Described element containing groove and locking groove have certain angle;

Described commutation retainer forms form with respect to the actuator radian with respect to the end face of described actuator, and the retainer that is provided with jagged retainer of most ladders and actuator in two ends is meshing with each other.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a local system exploded view of the present utility model.

Fig. 2 is a generalized section of the present utility model.

Fig. 3 is a local enlarged diagram of the present utility model.

Shown in Figure 3 as Fig. 1 one, the utility model 10 structures and known suitable, has a lever 11, lever 11 ends enlarge and form drive division 12, drive division 12 central authorities are provided with the driving room 13 of pentration for ccontaining actuator 20, in driving the locking groove 14 that room 13 nearly levers 11 places are provided with an opening form in addition, end in locking groove 14 centre is provided with a ringent element containing groove 15 for the direction control piece 30 of forming compound direction-control apparatus A, flexible member 40, injection that part 50 and commutation retainer 60 can be certain is pulled therebetween in the top, with the structure that reaches plyability and the demand of high torsion.

Element containing groove 15 of the present utility model is to be the form of joining with locking groove 14, element containing groove 15 and the locking groove 14 tangent openings that are angle, commutation retainer 60 is placed in the locking groove 14, direction control piece 30 is arranged in the element containing groove 15,60 of direction control piece 30 and retainers are provided with flexible member 40 and the top part 50 of pulling in addition and hold mutually, and making the top part 50 of pulling extend out to 15 of locking groove 14 and element containing grooves by direction control piece 30, direction control piece 30 gets final product that certain assembly is unlikely on the drive division 12 of spanner 10 deviates from.

Commutation retainer 60, wherein one side is the top supporting part 61 of the inner concave arc surface part 50 of pulling in system top, top, with promote controlling party to usefulness; Face also is an indent rounding top and bottom pattern in addition, and by two ends arc edge edge 621 ladders that are the dome arc being set arranges and the following retainer 62 that forms to the center, though and retainer 62 2 limits system is rounding top and bottom pattern, its center is still for being the blocking limit 620 on a plane, make retainer 21 staggered blockings convenient and actuator 20, and be provided with withstanding part 63, make it to become the retainer 21 that holds actuator 20 and raise up in the centre, and the relaxation state that is not fastened is reached the structural form of high torsion packing.

The utility model has the advantages that:

1. commutation retainer and actuator have the height fiting effect: its commutation retainer 60 retainers 62 2 ends are the arc edge edge 621 of a rounding top and bottom pattern, middle system is the blocking limit 620 on a plane, the retainer 60 that makes it to commutate needs to cooperate when rotating, be placed in the retainer 21 groove caves of actuator 20 in the equidirectional needs in rotation section, can more effectively reach to snap in fast to cooperate and brake.

2. increase its card and join the usefulness usability: its retainer 62 is the arc edge edge 621 of rounding top and bottom pattern, and the blocking limit 620 of establishing in the centre, cooperate blocking with retainer 21,, make actuator 20 can more reach fixing usefulness to increase the every fiting effect of its point, line, surface.
