Abstract
The utility model discloses a four-rod mechanism model comprising a machine rack, two rack connecting rods, and a connecting rod. One end of a rack connecting rod is hinged to one end of the machine rack, while one end of the other rack connecting rod is hinged to the other end of the machine rack. Through grooves are lengthways disposed on the top edges of the other ends of the rack connecting rods. A plurality of separated clamping slots are disposed on one sides of the through grooves. A bolt passing through a hole disposed on one end of the connecting rod passes through the through groove in order to be clamped to a clamping slot and then is fixed by a screw nut. A lengthways through groove is also disposed on the other end of the connecting rod. A plurality of separated clamping slots are disposed on one side of the through groove. Another bolt passes through a clamping slot on the end of the connecting rod and a corresponding clamping slot on the rack connecting rod and then is fixed by a screw nut. When the four-rod mechanism model is used, the screw nuts connecting the connecting rod with the rack connecting rods are unscrewed and then the bolts are moved in the through grooves and are located in different clamping slots. Finally, the bolts are screwed by the screw nuts in order that combinations with different forms such as a crank and rocker mechanism, a double-crank mechanism, and a double-rocker mechanism are achieved.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of four-bar mechanism model.
Background technology
Four-bar mechanism is a kind of physical construction of basis, because four-bar mechanism has multiple evolving form, conventional difficulty or ease in writing form make the student that an impression intuitively be arranged.
Chinese patent CN201498138U discloses a kind of hinge four-bar linkage structure demonstrator, it adopts, and an end is provided with a plurality of circular holes on connecting rod, connect different circular holes by bolt, realize the combination of various ways, but it just does trouble, must back out nut, take out bolt (perhaps taking off pin), could change the combination of different circular holes.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of four-bar mechanism model is provided, and this model structure is simple, and is easy to operate, can comparatively make things convenient for the multiple evolving form of combination.
For achieving the above object, the utility model adopts following technical proposals:
A kind of four-bar mechanism model, comprise frame, two side links and a connecting rod, one end of described two side links is articulated in the two ends of frame respectively, longitudinally have groove on the other end of side link, have the draw-in groove at some intervals on one side of groove, connecting rod one end is provided with a hole, pass bolt in the hole of this end, bolt passes groove and is stuck in one of them draw-in groove and by nut and fixes, the other end of connecting rod also has vertical groove, be interval with some draw-in grooves on one side of groove, the draw-in groove corresponding with it on the draw-in groove that passes this end of connecting rod by bolt and the side link, and fix by nut.
During use, outwarding winding connects the nut of connecting rod and side link, by mobile in groove bolt, bolt is positioned in the different draw-in grooves, twists admittedly through nut again, just can realize multi-form combination, for example, crank and rocker mechanism, double-crank mechanism, double rocker mechanism.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein 1. frames, 2. side link, 3. connecting rod, 4. groove, 5. draw-in groove, 6. bolt.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the four-bar mechanism model, comprise frame 1, two side links 2 and a connecting rod 3, one end of described two side links 2 is articulated in the two ends of frame 1 respectively, longitudinally have groove 4 on the other end of side link 2, have the draw-in groove 5 at some intervals on one side of groove 4, connecting rod 3 one ends are provided with a hole, pass bolt 6 in the hole of this end, bolt 6 passes groove 4 and is stuck in one of them draw-in groove 5 and by nut and fixes, and the other end of connecting rod 3 also has vertical groove 4, is interval with some draw-in grooves 5 on the side of groove 4, the draw-in groove 5 corresponding with it on the draw-in groove 5 that passes connecting rod 3 these ends by bolt 6 and the side link 3, and fix by nut.
During use, outwarding winding connects the nut of connecting rod 3 and side link 2, by mobile in groove 4 bolt 6, bolt 6 is positioned in the different draw-in groove 5, twists admittedly through nut again, just can realize multi-form combination, for example, crank and rocker mechanism, double-crank mechanism, double rocker mechanism.
Though above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
Claims (1)
1. four-bar mechanism model, comprise frame, two side links and a connecting rod, one end of described two side links is articulated in the two ends of frame respectively, it is characterized in that, longitudinally have groove on the other end of side link, have the draw-in groove at some intervals on one side of groove, connecting rod one end is provided with a hole, pass bolt in the hole of this end, bolt passes groove and is stuck in one of them draw-in groove and by nut and fixes, and the other end of connecting rod also has vertical groove, is interval with some draw-in grooves on the side of groove, the draw-in groove corresponding with it on the draw-in groove that passes this end of connecting rod by bolt and the side link, and fix by nut.
