Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1-Fig. 3, in a kind of detailed description of the invention, detent mechanism provided by the utility model, comprise the locating hole being located at second component 8, with the fairlead 6 being located at first component 9, fairlead 6 is provided with the pilot hole 11 coaxial with locating hole, pilot hole 11 is shoulder hole, pilot hole 11 is fitted with latch 3 along its axial activity, latch 3 is multidiameter, the little shaft part of multidiameter is plugged in the aperture section of shoulder hole, and the large shaft part of multidiameter is plugged in the macropore section of shoulder hole, and large shaft part inserts locating hole near the inserting paragraph of second component 8; Also be provided with spring 5 between latch 3 and pilot hole 11, spring 5 is located at the cascaded surface of shoulder hole and the cascaded surface of multidiameter.
Above-described embodiment arranges locating hole at second component 8, first component 9 is connected with the latch 3 along its axial mobilizing exercises, the location that locating hole realizes first component 9 and second component 8 is inserted by latch 3, the separate mobile that locating hole realizes second component 8 and first component 9 is departed from by latch 3, the locate mode positioning precision of this locating hole and latch 3 is high, high accuracy occasion can be applied to, improve follow-up efficiency of assembling, ensure carrying out smoothly of production.Meanwhile, spring 5 can increase stationarity and the fluency of latch 3 motion.By two cascaded surface mounting spring, dropping of spring can be prevented, and match respectively respectively by the large path of hierarchic structure and can ensure the stationarity that latch 3 moves further.
Can first component 9 be movable part in above-described embodiment, second component 8 be fixture; Also can second component 8 be movable part, first component 9 be fixture; Also the two can be movable part, embody rule depends on the circumstances.
First component 9 and fairlead 6 can be two parts, can be also a part, directly be located at first component 9 by pilot hole 11, and preferred first component 9 is two parts with fairlead 6, convenient processing.The two is assembled together after processing separately.Can be threaded connection or riveting in together, preferred first component 9 is provided with through hole, suitable with the outer wall of fairlead 6, and fairlead 6 interference fit is installed on through hole.This mode and easy to process, is convenient to again install, and the precision of detent mechanism can be made higher.
Latch 3 can slide axially along it and be plugged in fairlead 6, also can be plugged in fairlead 6 by spiral, and preferably the former, conveniently process, and latch 3 is easy to ensure with the relative position of first component 9.Pilot hole 11 is unthreaded hole, and latch 3 is optical axis, and the two both can along its axial sliding movement, again can around its axis rotation.
Spring 5 can be Compress Spring, also can be extension spring, or other shell fragment class spring.Be preferably Compress Spring, be placed between two cascaded surfaces, and be in compressive state all the time, namely latch 3 inserts locating hole and departs from locating hole, and spring 5 is in all the time and is compressed, and applies towards the elastic force in second component 8 direction to latch 3.
Be provided with position limiting structure between fairlead 6 and latch 3, position limiting structure is located in the stroke of latch 3.This structure can prevent latch 3 and pilot hole 11 from departing from completely, is convenient to the upset of first component 9 or second component 8, rotates and move.
Position limiting structure comprises the backing pin 4 being located at latch 3 and the stopper slot 10 being located at fairlead 6, and backing pin 4 is suitable with stopper slot 10.Processing is convenient in the mechanism of this stopper slot 10 and backing pin 4.
Position limiting structure also can be located at fairlead 6, and the inside as pilot hole 11 is provided with elastic bumps, as shell fragment, when latch 3 moves to the end of stroke, and elastic bumps clamping latch 3; Or be perpendicular to the flexible projection of pilot hole 11 axis, when latch 3 moves to the limit of stroke, projection stretches out clamping latch 3.Position limiting structure also can comprise the backing pin 4 being located at fairlead 6, and is located at the stopper slot 10 of latch 3, and the two cooperation is spacing.
Backing pin 4 and latch 3 can be structure as a whole, and also can be two parts, are preferably two parts, are installed on together respectively after processing, convenient processing.Backing pin 4 is installed on latch 3 by interference fit, and the two also can be threaded connection, or after matched in clearance, the axle head increase back-up ring of backing pin 4 realizes fixing.
Stopper slot 10 is positioned at fairlead 6 one end away from second component 8, and runs through the end face of this end.This structure is convenient to processing, and can realize the spacing of latch 3 stroke two ends.
Particularly, stopper slot 10 structure is as shown in Figure 3 U-type groove, can be one, also can be two, preferably two, and distributes about the axisymmetrical of fairlead 6, to ensure the stability in latch 3 sliding process.
Latch 3 is connected with handle 1 away from one end of second component 8.To facilitate the motor performance of latch 3.
Handle 1 is respectively equipped with coaxial pin-and-hole with latch 3, and handle 1 is connected by the bearing pin 2 through pin-and-hole with latch 3.Loosening of latch 3 and handle 1 can be prevented by the connection of bearing pin 2.Handle 1 and latch 3 also can be threaded connection, and move in relative rotation because latch 3 and fairlead 6 have, and are therefore threaded and easily cause loosening of handle 1 and latch 3.
Second component 8 is connected with positioning sleeve 7, and positioning sleeve 7 is located at by locating hole.Because latch 3 can repeatedly insert or depart from locating hole, the wearing and tearing of second component 8 can be prevented by increasing positioning sleeve 7.
Locating hole is taper hole, and inserting paragraph is the taper pin suitable with taper hole.Positioning precision can be improved further by the structure of taper pin.
When above-described embodiment is implemented, first positioning sleeve 7 is installed on second component 8, usually adopt the mode of interference fit to connect, fairlead 6 is installed on first component 9, usually adopts screw to connect, as shown in Figure 1; Then handle 1 drives latch 3 to rotate, after making backing pin 4 be positioned at stopper slot 11, because spring 5 is in compressive state, now the elastic force of spring 5 promotes latch 3 along the axial of pilot hole 11 near the direction of second component 8, the inserting paragraph of latch 3 inserts locating hole 7 the most at last, realizes the location of first component 9 and second component 8; When not needing location, manually pull out latch 3 to the direction with Ah Buddhist nun's second component 8, until backing pin 4 moves to fairlead 6 away from after one end end face of second component 8, axis around pilot hole 11 rotates latch 3, backing pin 4 is overlapped in fairlead 6, because spring 5 is in compressive state, now latch 3 also can not depart from pilot hole 11.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
