Abstract
The utility model discloses a bicycle E-type crank testing device, which comprises a base, wherein the base is fixedly provided with a main pedestal and an auxiliary pedestal, the main pedestal and the auxiliary pedestal are perpendicular to each other in direction, the upper end face of the main pedestal is connected to a pressing plate through screws, and opposite surfaces of the main pedestal and the pressing plate are provided with semicircular guiding grooves respectively; the auxiliary pedestal is provided with an adjusting groove, the adjusting groove is provided with a cantilever rod, and one end of the cantilever rod is provided with a nut. The bicycle E-type crank testing device can protect a crank in the testing process through arranging the semicircular guiding grooves in the main pedestal and the pressing plate so as to prevent deformation, one end of the crank is fixed by using cooperation of the cantilever rod and the adjusting groove, and the test can be finished quickly when a force is applied to the other end of the crank. The device disclosed by the utility model is simple in structure, very high in flexibility in use and capable of improving the testing efficiency to the maximum degree.
Description
Technical field
The utility model relates to cycle test frock technical field, is specifically related to a kind of E type crank proving installation for bicycle.
Background technology
In prior art, in the time that E type crank is tested, E type crank often can be due to after repeatedly stressed, there is fracture in other positions, in order to change this present situation, patent publication No. CN201425545Y discloses a kind of crank fatigue tester, it drives reciprocating motion of the pistons by cylinder, the crank being connected on piston rod is carried out to testing fatigue, although can test two cranks simultaneously, but structure is very complicated, cause the preliminary work before test various, reduce testing efficiency, and in the process of test, due to the protection lacking other positions, there will be the situation that produces distortion in the part of crank.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of bicycle E type crank proving installation, to reach efficient test fast, and can avoid crank to produce the object of distortion in the time of test.
For achieving the above object, the technical solution of the utility model is as follows:
Bicycle E type crank proving installation, comprise base, on described base, be connected with main basal base and supplementary base, described main basal base and described supplementary base direction are perpendicular, upper surface at described main basal base is connected with pressing plate by screw rod, offers respectively semicircle guide groove on the forward surface of described main basal base and described pressing plate; In described supplementary base, be provided with regulating tank, a cantilever rod is housed on described regulating tank, nut is equipped with in one end of described cantilever rod.
Further, on described base, be provided with several and have the through hole of female thread structure, on described through hole, be provided with standing screw.
Pass through technique scheme; the utility model by arranging semicircle guide groove on main basal base and pressing plate; can in test process, form to crank protection, prevent distortion, utilize the cooperation of cantilever rod and regulating tank; one end of fixing E type crank; when the other end of E type crank is exerted pressure, can complete fast test, this apparatus structure is simple; the dirigibility using is extremely strong, can maximized lifting testing efficiency.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 2 is the structural representation in test process of the disclosed bicycle E of the utility model embodiment 1 type crank proving installation.
Numeral and the represented corresponding component title of letter in figure:
1, base; 2, main basal base; 3, pressing plate; 4, screw rod; 5, supplementary base; 6, cantilever rod; 7, regulating tank; 8, nut; 9, standing screw; 10, E type crank; 11, application of force rod.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1, bicycle E type crank proving installation, comprise base 1, on described base 1, be connected with main basal base 2 and supplementary base 5, described main basal base 2 is perpendicular with described supplementary base 5 directions, upper surface at described main basal base 2 is connected with pressing plate 3 by screw rod 4, on the forward surface of described main basal base 2 and described pressing plate 3, offers respectively semicircle guide groove, in described supplementary base 5, be provided with regulating tank 7, one cantilever rod 6 is housed on described regulating tank 7, nut 8 is equipped with in one end of described cantilever rod 6, in conjunction with Fig. 2, the middle part of E type crank 10 is positioned in the semicircle guide groove of described main basal base 2, pressing plate 3 is covered to the upper surface at described main basal base 2, utilize screw rod 4 fixation clips 3 and main basal base 2, E type crank 10 can be fixed, make one end of E type crank 10 be positioned at the below of cantilever rod 6 simultaneously, according to the length of E type crank 10, adjust the position of cantilever rod 6 in regulating tank 7, lock with nut 8, cantilever rod 6 can be fixed in described regulating tank 7, the other end by 11 pairs of E type cranks 10 of application of force rod is vertically exerted pressure, because the other end has the fixing of cantilever rod 6, there is the fixing and protection of main basal base 2 and pressing plate 3 centre, can realize the test position of E type crank 10 is precisely tested, and there is distortion in other positions that can prevent E type crank 10, not only protect product, and promote testing efficiency.
Further, on described base 1, be provided with several and have the through hole of female thread structure, on described through hole, be provided with standing screw 9, by standing screw 9, base 1 can be fixed on other equipment and support the use, promoted the dirigibility of operation.
Above-described is only the preferred implementation of the utility model bicycle E type crank proving installation; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
