Abstract
The utility model relates to a nonlinear curve eccentric cam type fast clamping device which is characterized in that an eccentric cam reaches the peak when a handle of a nonlinear curve eccentric cam is opened or closed, so that the clamping function is achieved; the curved surface of the cam adopts a nonlinear curved surface; and the self-locking and the anti-fall off functions are achieved. When a wrench is pulled, the eccentric cam reaches the rock bottom; and a fixed clamping groove and a movable clamping groove are released under the action of a tension spring. The clamping force is adjusted through adjusting the connection threads of a pull rod sleeve and a pull rod shaft; and the utility model has the advantages of fast assembly and disassembly, fast clamping, realization of self-locking, looseness prevention, compact structure, small volume, light weight, convenient operation and the like, and can solve the problem in a traditional clamping device such as slower installation, complicated operation and low efficiency.
Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of nonlinear curve eccentric earn quick clamping device.
Background technology
At present, the mounting means such as front handlebar of taking aim at tool, rifle adopt the screw rod tension more, generally need to be equipped with annexes such as spanner, not only to carry inconvenience in the actual use, and mount and dismount time-consuming, effort.Also have a kind ofly to clamp fast by the inclined-plane friction, actual being equivalent to, strengthened pitch, needs attached assistant engineer's tool equally, could realize clamping, and actual efficiency is not high.
In addition, installing at other similar guide rails, generally also is to adopt screw rod tension formula to install, or the screw in compression formula installs, and all must be equipped with accessory tools such as spanner, installs slowlyer, also needs to carry at any time instrument, actual use inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of nonlinear curve eccentric earn quick clamping device, solves existing clamping device slow, complicated operation, the problem of inefficiency are installed.
Technical solution of the present utility model is: a kind of nonlinear curve eccentric earn quick clamping device, comprise body, be arranged on the fixed card slot of body below, its special character is, this device also comprises the movable draw-in groove that is arranged on body below one side, described fixed card slot is arranged on body opposite side and corresponding with this activity draw-in groove, laterally be provided with the hole along body in described fixed card slot and the movable draw-in groove, be provided with drag link sleeve in the hole in the wherein said fixed card slot, the external diameter of this drag link sleeve is arranged on the outside in this hole greater than the termination of the diameter in this hole, and is provided with butterfly spring between near the fixed card slot outside this termination and this hole; External diameter is arranged in this hole less than the other end of the drag link sleeve of the diameter in this hole, and this end extends in this hole, and establishes the screw of screw thread in being provided with in this end; Be provided with pull rod shaft in the hole in the described movable draw-in groove, an end of this pull rod shaft is a bolt, is connected with the screw of establishing screw thread in the described drag link sleeve; The other end extends to the outside of movable draw-in groove, and its termination is provided with the pin shaft hole that is used for connecting by bearing pin nonlinear curve eccentric cam handle; The nonlinear curve eccentric cam portion of this nonlinear curve eccentric cam handle is connected by the termination that bearing pin and described pull rod shaft are arranged on the movable draw-in groove outside, and this nonlinear curve eccentric cam portion protrudes to pull rod shaft when the shaft arm of nonlinear curve eccentric cam handle is close to the movable draw-in groove outside; Described movable draw-in groove is provided with the tension spring of elastic force greater than described butterfly spring between vertical two ends of body and movable draw-in groove.
Described fixed card slot and movable draw-in groove are applicable to the Buddhist nun's guide rail installation of pick up spit of fland.
The enforcement of this programme is fashionable by operation nonlinear curve eccentric cam handle pass, and eccentric cam is peaked, and realizes clamping function; Cam curved surface is a Nonlinear Curved, and realizes the self-locking anti-drop function.During cocked spanner, eccentric cam is touched the bottom, under the tension spring effect, fixed card slot and movable draw-in groove unclamp.The clamping force size of the clamping of this programme is to realize the adjustment of clamping force by the connecting thread of adjusting drag link sleeve and pull rod shaft, be a kind of quick loading and unloading, clamping and the real self-locking of energy fast, prevent to become flexible, have the compact conformation of being, volume is little, in light weight, is convenient to advantages such as operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the C of Fig. 1 is to view.
The specific embodiment
Referring to Fig. 1,2, device for carrying out said of the present utility model comprises: body 1, fixed card slot 2, movable draw-in groove 3, drag link sleeve 4, pull rod shaft 5, butterfly spring 6, latch 7, nonlinear curve eccentric cam handle 8, tension spring 9,10 are formed.Wherein fixed card slot 2 and movable draw-in groove 3 are arranged on the lower end of body 1.Drag link sleeve 4 is located in the interstitial hole of fixed card slot 2, and an end is arranged on the outside of fixed card slot 2, and the other end is connected with the threaded one end of pull rod shaft 5.Be provided with butterfly spring 6 between drag link sleeve 4 one ends and the fixed card slot 2.The other end of pull rod shaft 5 is arranged in the hole of movable draw-in groove 3 centres, and extends to the outside of movable draw-in groove 3, and is connected with nonlinear curve eccentric cam handle 8 by latch 7.Between movable draw-in groove 3 two ends and the fixed card slot 2, be respectively arranged with tension spring 9,10.
Scheme implementation of the present utility model is when reaching the A position by operation nonlinear curve eccentric cam hand 8 handles, eccentric cam to be peaked (at this moment, cam protrudes to pull rod shaft 5), realizes clamping function; Cam curved surface is a Nonlinear Curved, and realizes the self-locking anti-drop function.When cocked nonlinear curve eccentric cam handle reaches to the B position, eccentric cam is touched the bottom, under tension spring 9,10 effects, fixed card slot 2 unclamps with movable draw-in groove 3.The clamping force size of clamping be by the connecting thread of adjusting drag link sleeve 4 and pull rod shaft 5 (being threaded between pull rod shaft 5 and the drag link sleeve 4 is adjustable) is connected how much, the length in the change pull rod shaft 5 screw-in drag link sleeves 4 can realize the adjustment of clamping force.
