The specific embodiment
Because the present invention discloses a kind of open ratchet spanner, the ratchet start principle of wherein being utilized has been that the correlative technology field technical staff can understand, so with hereinafter explanation, no longer do complete description.Simultaneously, institute's reference is graphic hereinafter, is to express the structural representation relevant with feature of the present invention, does not also need according to the complete drafting of actual size, close chat earlier bright.
See also Fig. 1, Fig. 2, shown in Figure 3, it is respectively three-dimensional exploded view, three-dimensional combination figure and the cutaway view of the utility model open ratchet spanner 100.
Person as seen in FIG., the profile of the utility model open ratchet spanner 100 mainly is made of a lever 11 and two phase pair of jaw parts 13.Described two phase pair of jaw parts 13 are that the end by described lever 11 extends, and keep an open end separately.According to present embodiment, described two jaw portion coating scopes are 300 degree that are about a circumference, and the open end of described two jaw portions 13 forms relative operation repetitive face 131.In addition, described two jaw portions 13 define accommodating unit jointly; According to present embodiment, described accommodating unit comprises a ratchet storage tank 15, two elastic component storage tanks 171 and two clamping piece storage tanks 173.Wherein, each above-mentioned elastic component storage tank 171 is one group with each above-mentioned clamping piece storage tank 173, is connected with each other, and is communicated with described ratchet storage tank 15.And the combination of two groups of elastic component storage tanks 171 and clamping piece storage tank 173 is apart one section predeterminable range, is arranged on described ratchet storage tank 15 outsides.
The utility model open ratchet spanner 100 also comprises a ratchet assembly that is contained in described jaw portion 13 accommodating unit.According to present embodiment, described ratchet assembly comprises a non-enclosed ratchet 21, two elastic components 23 and two clamping pieces 25, among the corresponding respectively ratchet storage tank 15 that is contained in described accommodating unit, elastic component storage tank 171 and the clamping piece storage tank 173.The interior Zhou Dingyi of described non-enclosed ratchet 21 has complex operation face 213, and the periphery definition has plural hook tooth 211.Simultaneously, each described clamping piece 25 comprises one and is contained in the pivot portion 253 of described clamping piece storage tank 173 and plural number corresponding to the clamping tooth 251 of described hook tooth 211.
The complex operation face 213 in week in this further specifies described non-enclosed ratchet 21.In the illustrated embodiment, described complex operation face 213 is five operating surfaces of corresponding orthohexagonal.More specifically, described complex operation face 213 is the operating surfaces on wantonly five limits in the corresponding positive hexagonal (hexagon)nut.
According to above setting, can be under the elasticity ejection effect of the corresponding elastic component 23 movable hook tooth 211 that push against described non-enclosed ratchet 21 of described clamping piece 25, and make described ratchet assembly be unidirectional rotation with respect to described lever 11 and described jaw portion 13.
It should be noted that, though described in the present embodiment two jaw portions 13 coating scopes are 300 degree that are about a circumference, but in fact, as long as the spacing of described two jaw portion 13 open ends is wide less than a maximum diameter of described non-enclosed ratchet 21, not exclusively break away from the effect of described two jaw portions 13 controls in the time of can realizing described non-enclosed ratchet 21 is rotated.In other words, described coating scope only must reach more than 180 degree of a circumference.In addition, in case described two jaw portions 13 coating scopes are greater than 180 degree, then its open end promptly transfers relative state to, thus can exempt user's body part in operation, clothing or the unfavorable situation of the careless mounting board of other objects between described jaw portion 13 and non-enclosed ratchet 21.In other words, the coating scope can be guaranteed handling safety and smooth and easy greater than the jaw portion 13 of 180 degree, therefore is for implementing necessary condition of the present utility model.
Another technology of the present utility model focuses on: described clamping tooth 251 should be greater than the width of described ratchet 21 1 openings with the width of described hook tooth 211 contact-making surfaces.With present embodiment, promptly be the distance of the width sum total of the clamping tooth 251 of described two clamping pieces 25 and described hook tooth 211 contact-making surfaces greater than 131 in described two jaw portions 13 operation repetitive faces.Please refer to Fig. 4, Fig. 5, Fig. 6, is the example operation with one hexagonal (hexagon)nut 90 of pine commentaries on classics counterclockwise.According to above-mentioned structure, the utility model open ratchet spanner can be linked in hexagonal (hexagon)nut 90 easily as existing open-end wrench; Then, rotate in the process of the utility model open ratchet spanner with drive surface 213 rotating screw caps 90 of ratchet 21 the operator, ratchet 21 rotates, and when one in corresponding two clamping pieces 25 of its opening, another clamping piece 25 still can provide the effect of unidirectional rotation control to ratchet 21.
In addition, because the shortcoming of the existing limited ratchet structure of ratchet spanner intensity, two jaw portion 13 open ends of the open ratchet spanner of present embodiment form relative operation repetitive face 131, thus can utilize the intensity performance of jaw portion 13 itself as existing open-end wrench effectively pine change or screw the advantage of workpiece.Fig. 7 promptly represents to work as described hexagonal (hexagon)nut 90 under locking state, the user can be with the operation repetitive face 131 of open ratchet spanner corresponding to hexagonal (hexagon)nut 90, nut 90 application of forces of utilizing the intensity of jaw portion 13 tentatively will lock are at present slightly unclamped, then carry out follow-up pine with ratchet assembly again and change operation, avoid excessive rotation direction resistance directly to damage and wheel construction.
Otherwise, if when desiring to screw nut 90, the turning open ratchet spanner of the present utility model of user, as shown in Figure 8, the above-mentioned step of reverse operating then; Also promptly first drive surface 213 with non-enclosed ratchet 21 is secured to nut 90 to a certain degree, then utilize the operation repetitive face 131 of two jaw portions 13 that nut 90 further is secured to desirable state, fully realize integrating the multiple purposes of open-end wrench and ratchet spanner with single instrument.
From the above as can be known, the advantage of the utility model open ratchet wrench comprises and is easy to the fit workpiece, is beneficial to The operation of repeatedly rotating and the desirable strength when the turn object is provided, thus avoid ratchet spanner because of the object mistake Big resistance produces and damages, and guarantees operation ease and life tools.
More than explanation is just illustrative for the utility model, and nonrestrictive, ordinary skill Personnel understand, in the situation that does not break away from the spirit and scope that claim limits, can make many modifications, Change or equivalence, but all will fall within the protection domain of the present utility model.
