Detailed description of the invention
Further illustrate the utility model with specific embodiment with reference to the accompanying drawings.
As shown in accompanying drawing 1-5, the one that the utility model provides is caught catch gear, comprises the portion of catching 1 and the portion 2 that is hunted down, wherein: catch portion 1 and comprise cavity 11, contact ring 102, some Compress Springs 103, some ratchets 104 and some torsion springs 105; Be hunted down portion 2 comprise catch 201, pipe link 202 and erecting frame 203.
Cavity 11 comprises a cavity top board 101, cavity top board 101 is circular, circle ring inner wall bottom is provided with some grooves 112, some ratchets 104 radially arrange along annulus, in the fixedly embedded some grooves 112 of one end difference of ratchet 104, be rotatable fixing with circle ring inner wall, because ratchet 104 one end embed groove, therefore rotate to cavity side only, the other end of some ratchets 104 does not contact, its mid point all drops on a circular arc, surround a sub-circular cavity 141, on some ratchets 104, be provided with the torsion spring 105 radially arranging along circle ring inner wall for it is reset to.
One end of some Compress Springs 103 connects the upper surface of cavity top board 101, and the other end connects the bottom surface of contact ring 102, makes the central axes of contact ring 102 and cavity top board 101; In some Compress Springs 103, be provided with a guidepost 131, one end of guidepost 131 is fixedly connected with the upper surface of cavity top board 101, and the other end is through the pilot hole 132 of the correspondence position of the bottom surface of contact ring 102.Or one end of guidepost 131 is fixedly connected with the bottom surface of contact ring 102, the other end is through the pilot hole of the correspondence position of the upper surface of cavity top board 101.Pilot hole is arranged on the junction of cavity top board 101 or contact ring 102 and Compress Spring 103, and in the time that Compress Spring stretches or compress, guidepost play the guiding role, and makes the annulus central axes all the time of contact ring and cavity top board.Pilot hole also can be set, in some Compress Springs 203, be provided with a scalable guidepost, one end of scalable guidepost connects the upper surface of cavity top board, the other end connects the bottom surface of contact ring, in the time that Compress Spring stretches or compress, scalable guidepost is together flexible, makes the annulus central axes all the time of contact ring and cavity top board.
Pipe link 202 two ends connect respectively catches a center of 203 bottom surfaces and erecting frame 201, in the present embodiment, catch a bottom surface of 203 for circular, its diameter is greater than the diameter in sub-circular cavity, can not pass sub-circular cavity, the diameter of catching a bottom surface of 203 is less than the internal diameter of contact ring and the internal diameter of cavity top board, the diameter of pipe link 202 is less than the diameter in sub-circular cavity, can pass sub-circular cavity.
As shown in Figure 1, in the present embodiment, catch head and connect the combination of a cylinder for frustum of a cone bottom surface, certainly catching head also can adopt the frustum of a cone or circular cone, circular cone bottom surface to connect the combination of a cylinder, adopt the frustum of a cone or cone shape can relax the impulsive force to torsion spring 105 on ratchet 104, contribute to extend the service life of torsion spring.
When the length of pipe link is greater than Compress Spring is compressed to shortest length in deformation range, contact ring upper surface is the surperficial distance near cavity side to ratchet, and when being less than Compress Spring and not being subject to external force, contact ring upper surface is the surperficial distance near cavity side to ratchet.
The portion of catching is arranged on an objective body, and the portion of being hunted down is arranged on a driver train; Or the portion of being hunted down is arranged on an objective body, the portion of catching is arranged on a driver train; Or two the portion of catching be separately positioned on two driver trains; Below all make the portion of catching and the portion of being hunted down can do relative near or away from motion.
Catch portion 1 and move to the portion's of being hunted down 2 directions with respect to the portion of being hunted down 2, first contact ring 102 contacts with erecting frame 201, and in the process of moving in the portion of catching 1, Compress Spring 103 is compressed, and guidepost 131 is through the pilot hole 132 on cavity top board 101;
Catch portion 1 and move forward, contact with ratchet 104 until catch 203, ratchet 104 overturns to cavity side under a promotion of catching 201;
Catching portion 1 continues with respect to the portion of being hunted down 2 to the portion's of being hunted down 2 direction motions, when moving to, the portion of catching 1 catches 203 through ratchet 104, ratchet 104 is got back to the position radially arranging along annulus at initial cavity body top under the effect of torsion spring 105, realizes catching objective body.
Catching portion 1 changes into respect to the portion of being hunted down 2 and moving to reversing sense, under pressure spring 103 compression force, contact ring 102 promotes erecting frame 201 to the direction that is hunted down, because ratchet 104 resets, to catch the locking of head bottom spacing in cavity 11, the compression force of Compress Spring 103, on erecting frame 201, has realized the holding tightly of erecting frame 201, and the locking of objective body is completed.
Above-mentioned disclosed be only specific embodiment of the utility model, this embodiment is only that clearer explanation the utility model is used, and not to restriction of the present utility model, the changes that any person skilled in the art can think of, all should drop in protection domain.
