The friction self-locking rope clip has the advantages of functions of manual pre-clamping and automatic locking, simple structure, large rope clipping force, high safety and reliability, and the like.
Description
Technical field
The invention belongs to automobile impact test apparatus, be specifically related to a kind of friction self-locking formula rope-grippers.
Background technology
At present, the rope-grippers that adopts of domestic automobile collision experiment can be divided into fixed and two kinds of pulling types; Fixed grip begins to be fixedly connected with drag rope all the time to end from impact test, can't realize colliding the circulation of line, troublesome poeration.And for fixed rope clip the collision moment and the overtension of traction rope, easily formation accident; Can realize collision line realization circulation for traditional pulling type rope-grippers, but its complex structure, rope clip module force also is restricted due to its structure, can't further improve; In the present locking mode of understanding, the offset cam locking mode is due to its simple structure, can quick locking and the latching characteristics of offset cam be used widely in various latch mechanisms, but its coupling mechanism force is little, reliability is not high.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, rope clip module force is large, safe and reliable friction self-locking formula rope-grippers.
Realize that the technical scheme that the object of the invention adopts is: friction self-locking formula rope-grippers comprises base, the bottom of base is provided with a pass through openings, a side along the pass through openings direction on base is provided with the hinge slider that slides in the direction, be hinged with movable claw on hinge slider watt corresponding with described pass through openings, embrace rope parts as consisting of together with fixed claw watt and movable claw watt establishing the part that forms described pass through openings on the base of hinge slider; Be positioned at the pass through openings opposite side on base and be provided with the offset cam that coordinates with movable claw watt mantle friction, offset cam is provided with handle.
Be equipped with tusk on the occlusal surface of described fixed claw watt and movable claw watt.
Adopt the slide rail sliding groove structure to be connected between described hinge slider and base.
Be provided with retracing spring between described movable claw watt and hinge slider.
Described base is provided with the reinforcement cover with hinge slider and movable claw watt parcel.
Adopt the detachable type grip of said structure to have manually pre-the clamping and automatic fastening function.Pass through openings on the bottom is used for placing the cable wire of traction impact test automobile, fixed claw watt and movable claw watt are used for cable wire is embraced folder, rotate offset cam by handle movable claw watt is applied acting force, movable claw watt is clamped steel cable in advance, also can utilize steel cable to pull and drive the outside slippage of hinge slider, make offset cam watt further apply acting force to movable claw, realize auto-lock function.The present invention is simple in structure, and rope clip module force is large, and is safe and reliable.
The invention will be further described below in conjunction with accompanying drawing.

Embodiment
Embodiment 1
See Fig. 1, Fig. 2, friction self-locking formula rope-grippers comprises base, and base comprises left base 9 and right base 1, left and right base 9,1 is connected integrant web joint 6; Web joint 6 is divided into upper and lower web joint 601,602; Form a pass through openings A between left and right base 9,1 bottom, be provided with along the left base 9 of pass through openings A direction one side the hinge slider 7 that slides in the direction; Adopt dovetail slide rail sliding groove structure 14 to be connected between hinge slider 7 and left base 9, left base 9 is provided with dovetail groove 14, and the bottom of hinge slider 7 is provided with dovetail slide rail 141 and coordinates with dovetail groove 141 on left base 9; The dovetail slide rail 141 of hinge slider 7 is provided with spacing hole 15; Be hinged with movable claw watts 10 with long pin 13 on hinge slider 7 corresponding with described pass through openings A, be provided with return torsion spring 12 between movable claw watts 10 and hinge slider 7; Embrace rope parts as consisting of together with fixed claw watt and movable claw watts 10 establishing on the left base 9 of hinge slider 7 part that forms described pass through openings A; Be equipped with tusk 16 on the occlusal surface of fixed claw watt and movable claw watts 10, to increase the interlocking to steel cable 8; Be positioned on the right base 1 of pass through openings A opposite side and be provided with and the movable claw watt offset cam that 10 mantle frictions coordinate 2 by bearing pin 11, on the periphery of offset cam 2, nearest position, the tool center of circle is provided with a platform 201, and offset cam 2 is provided with handle 4; Be provided with the reinforcement cover 5 with hinge slider 7 and movable claw watt 10 parcels between the web joint 6 of base, strengthen cover 5 and be provided with the breach corresponding with offset cam 3; Lower connecting plate 602 is provided with the breach 602a corresponding with hinge slider 7, so that hinge slider 7 can pass in slippages, the spacing hole 15 that also is provided with dovetail slide rail 141 on spacing block set 602b and hinge slider 7 coordinates.
Principle of work:
In service at the vehicle impact testing line, require rope-grippers to complete two processes that steel cable 8 is clamped and loosens:
Clamping process: the present invention has manually pre-the clamping and automatic fastening function in clamping process.See Fig. 1, steel cable 8 is placed in pass through openings A on base, depress movable claw watts 10, drive offset cam 2 rotations by handle 4 being bestowed certain moment of torsion, because the rotation of offset cam 2 increases its lock radius gradually, the friction force that applies by its peripheral surface simultaneously drive movable claw watts 10 and hinge slider 7 do together outside sliding motion and clockwise rotate (hinges) thus hold steel 8 tightly, realize manually pre-clamping; In the process of drawing outside steel cable 8 is stressed, cross gear pair and be delivered to offset cam 2 lock radius is further increased because the friction with movable claw watts 10 will drive pawl watt 10 further outer Mobile Communication, realize automatic fastening function.
The process of loosening: utilize mechanical hook-up collision handle 4 backward rotation offset cams 2, reduce rapidly lock radius, the elastic force of return torsion spring 12 opens movable claw watts 10 counterclockwise, thereby realizes loosening steel cable 8.When the platform 201 on the periphery of offset cam 2 was in movable claw watt 10 mated position, movable claw watts 10 opened fully.
Hinge slider in the present invention also can adopt the slide rail sliding groove structure of other employing to be connected with left base, and as shown in the figure, hinge slider has the slide rail of T shape head, is clipped between the top and the bottom 901,902 of base 9 in chute.
