Embodiment
Further describe technological scheme of the present invention below, but described in claimed scope is not limited to.
As shown in figures 1-4, a kind of labour-saving interlock positioning and locking structure, comprises connecting rod 1, claw 2, screw rod 3, frame 4, universal joint cross 5, guide rail 6, locking mechanism 7, spring bearing housing 8, locating slot 10 and leaf spring 11.
Described guide rail 6 level is arranged in frame 4, and guide rail 6 is provided with locating slot 10, and described locating slot 10 is V-shaped groove; Frame side is provided with spring supporting seat 8, and described spring supporting seat 8 establishes leaf spring 11, described leaf spring 11 and guide rail 6 side-by-side parallel; In order to reduce the horizontal applied force of leaf spring 11 pairs of spring bearing housings 8, the attachment hole of leaf spring 11 one end is designed to waist shaped hole.
Described connecting rod 1 is perpendicular to guide rail 6 horizontal arrangement below guide rail 6, and described screw rod 3 is connected to connecting rod 1 two ends, and is equipped with universal joint cross 5 between connecting rod 1 and screw rod 3; Matching installation is on the screw rod 3 at connecting rod 1 two ends respectively for described claw 2, and wherein screw rod 3 end is fixedly connected with locking mechanism 7, for being locked to screw rod 3; Described locking mechanism 7 comprises ratchet 71 and dead bolt 72, and the profile of tooth of described ratchet 71 is stepped tooth.
Screw rod 3 thread rotary orientation at described connecting rod 1 two ends is contrary, and described two claws 2 are relative and two screw rods 3 Matching installation respectively, moves in opposite directions or dorsad to realize two claws 2 simultaneously; Described claw 2 is provided with claw inclined-plane 21, and inclination angle of inclined plane is 20 ~ 30 °, and the claw under claw inclined-plane 21 2 is provided with stiffening rib 22, to guarantee that claw 2 has sufficient intensity, to provide larger impacting force.
In order to increase the hardness of part surface, need to carry out chrome-faced process to ratchet 71 and claw 2.Leaf spring 11 adopts 60Si2CrA to manufacture, and effects on surface carries out phosphorating treatment.In order to seal locking driving mechanism, lubricate and protect, have also been devised the protective elements such as dust-proof cover.
Combination roller 9 is formed by two roller parallel combinations, and one of them roller is positioned on guide rail 6, and another roller is positioned on leaf spring 11; The working surface of leaf spring 11 is a little less than the working surface of guide rail 6.
The present invention, by arranging the locating slot 10 of V-arrangement on guide rail 6, when roller 9 is rolled to locating slot 10 place of guide rail 6, because combination roller 9 enters in locating slot 10, realizes roller location; Support and connection block 12 moves down with combination roller 9, contacts with guide rail 6.Then by double helix screw rod 3 transmission, make the claw 2 be arranged symmetrically with simultaneously to intermediary movements, the support and connection block 12 being provided with combination roller 9 is compressed by claw inclined-plane 21, combination roller 9 is made to overcome the elastic force of leaf spring 11, leaf spring 11 is depressed, make the lower plane of support and connection block 12 be close to guide rail 6 plane, thus make support and connection block 12 realize realizing locking in the position location of guide rail 6; After locking mechanism locking, by the latching characteristics of screw rod 3, realize treating the locking of locking mechanism, dead bolt 72 is inserted in the draw-in groove of ratchet 71, realize further locking and positioning and locking.When locking mechanism unlocks, dead bolt 72 is taken out from the draw-in groove of ratchet 71, rotating screw bolt 3 adjusts claw 2 and returns original position, leaf spring 11 recovers deformation simultaneously, combination roller 9 is propped up, support and connection block 12 getaway 13 plane, avoids support and connection block 12 and guide rail 6 planar friction, is scratched by guide rail 6; Now can realize load by less thrust again to move on guide rail 6.
Be more than the optimum embodiment of technical solution of the present invention; but should not be interpreted as that the scope of theme of the present invention is only limitted to above embodiment at this point; without departing from the idea case in the present invention described above; all various amendments of making according to ordinary skill knowledge and customary means and replacement, all should be included in protection scope of the present invention.
