These purposes of the present invention, characteristics and advantage will be below embodiment, detailed exposure in accompanying drawing and the claim.
Description of drawings
Fig. 1 tightens up the structural representation of state for the quick hold-down mechanism of the present invention;
Fig. 2 is the structural representation of the quick hold-down mechanism relaxation state of the present invention.
Embodiment
See also Fig. 1,2, the present invention is a kind of quick hold-down mechanism, comprise the handle bracket 7 that is provided with cavity, be installed in rotation on the handle that is provided with cavity 9 at handle bracket 7 rear portions, be installed in the locating sleeve 1 of handle bracket 7 front portions, be equipped with pull bar 5 in the cavity of described handle bracket 7, handle 9 is withstood in the rear end of pull bar 5, the front end of pull bar 5 is connected with and tightens up cover 2, tighten up the inner chamber that cover 2 is located in locating sleeve 1, between pull bar 5 and the handle bracket 7 flexible member 6 is installed, flexible member 6 backs down handle 9 in the rear end of free state lower link 5, and flexible member 6 will tighten up the outside of the front end release locating sleeve 1 of cover 2 at the front end of impaction state lower link 5.Above-mentioned structure can realize compressing fast of automobile vacuum booster idle motion monitor station bolt easily, makes that not only operation is easy to loading and unloading, save the plenty of time, improved detection efficiency, and guaranteed accuracy of detection to a certain extent, and this mechanism structure is simple, loads and unloads easy.
Described handle 9 adopts straight pins 8 to be installed on the handle bracket 7, handle 9 can straight pin 8 for fulcrum rotates, this simple in structure, easy to operate, cost is low.Described flexible member 6 adopts stage clip, and an end of stage clip withstands the rear portion of pull bar 5, and the other end withstands the front portion of handle bracket 7, and is simple in structure.Described pull bar 5 adopts screw 4 to be connected with tightening up between the cover 2, connects more firm.The described cover 2 that tightens up is combined into cylindric forming by four arc-like sheets, tighten up in the cover 2 and be provided with elasticity O type circle 3, elasticity O type circle 3 can make the leading section of four arc-like sheets open laterally when the leading section of four arc-like sheets stretches out locating sleeve 1, and described elasticity O type circle 3 is positioned at the rear portion of tightening up cover 2.Tighten up cover 2 interior ring recess borders fillet and certain roughness are all arranged.Tightening up on cover 2 medial surfaces has internal thread, the screw thread of damage bolt in the time of can avoiding hold-down bolt.This structure is loosened and is tightened up easy to operate, simple in structure.The rearward end of described pull bar 5 is a spherical shape, and described spherical shape contacts with the inboard of handle 9, contacts effectively, and operating handle is good.Handle 9 must have certain roughness to guarantee at friction portion, guarantees that with handle bracket 7 places certain angle makes mechanism be in self-locking state at impaction state.
