Abstract
The utility model discloses a swing guide rod device characterized by adjustability of rack length. The swing guide rod device comprises an eccentric disc, a guide rod, a slider, a screw rod, a rack and a handle. The lower end of the screw rod is connected with the handle after passing through a pedestal of the rack; the screw rod can be movably installed in a guide groove of the guide rod through the slider; and the eccentric disc is connected with the guide rod and the upper end of the rack. When the eccentric disc rotates around one point on the rack, the guide rod swings around the slider and the slider slides along the guide groove. When the handle is rotated, the slider can slide in the guide groove of the guide rod through the screw rod and thus the length of the rack can be adjusted. When the slider is moved vertically through rotation of the screw rod via the hand wheel, the length of the rack can be changed and thus the swing angle of the guide rod can be changed. The swing guide rod device is simple in structure and relatively low in cost.
Description
Technical field
The utility model relates to a kind of pendulum guide rod, relates in particular to the length-adjustable pendulum guide rod device of a kind of frame.
Background technology
At present, in the guide-bar mechanism that swings, the method that is generally used for regulating the pendulum angle of guide rod is the length that adds big crank, but because the length of crank after strengthening can not greater than the length of frame, cause the pendulum angle that can not regulate to greatest extent fork.
Summary of the invention
The purpose of this utility model provides a kind of frame length-adjustable pendulum guide rod device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises eccentric disc, guide rod, slide block, screw rod, frame and handle, the lower end of described screw rod is connected with described handle by the base of described frame, in the guide groove that is installed on described guide rod that described screw rod can move by described slide block, described eccentric disc respectively with described guide rod be connected the upper end of frame and be connected.
Slide block described in the utility model is that nut can slide in the guide groove of described guide rod.
The beneficial effects of the utility model are:
The utility model provides a kind of and moves up and down slide block by the hand wheel rotating screw rod, changes the length of frame, thereby changes the pivot angle of guide rod; The utlity model has simple in structure and lower-cost advantage.
Description of drawings
Fig. 1 is the length-adjustable pendulum guide rod unit engineering of frame described in the utility model figure;
Among the figure: 1-eccentric disc, 2-guide rod, 3-slide block, 4-screw rod, 5-frame, 6-handle.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: the utility model the utility model comprises eccentric disc 1, guide rod 2, slide block 3, screw rod 4, frame 5 and handle 6, the lower end of screw rod 4 is connected with handle 6 by the base of frame 5, in the guide groove that is installed on guide rod 2 that screw rod 4 can move by slide block 3, eccentric disc 1 is connected with the upper end that guide rod 2 is connected with frame respectively.
As shown in Figure 1, operation principle of the present utility model is as follows:
During eccentric disc 1 a bit rotating on frame 5, guide rod 2 is swung and guide groove slides along slide block around slide block 3; Turning handle 6 can make slide block 3 slide in the guide groove of guide rod 2 by screw rod 4, the length of adjustable rack 5; When with hand wheel rotating screw rod 4, when moving up and down slide block 3, just can change the length of frame 5, thereby change the pivot angle of guide rod 2.
