It is good, it may appear that stuck phenomenon.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, and linkage performance is good, extending apparatus that will not be stuck
Linkage structure.
In order to achieve the above object, the technical solution of the utility model is：A kind of linkage structure of extending apparatus, including branch
Strut, head rod, rotating bar, the first gangbar, the second gangbar, the second connecting rod and pedal, the head rod
It is connected with one end of support bar, one end of rotating bar and support bar is rotatably assorted, and one end and the rotating bar of the first gangbar are hinged,
The other end is hinged with pedal, and one end and the support bar other end of the second gangbar are hinged, and one end of the other end and pedal is hinged, the
One end of two connecting rods is hinged with the first gangbar, and the other end is hinged with the second gangbar.
The support bar is provided with the first spacing block set, and when rotating bar rotates, rotating bar offsets with the first spacing block set.
Second gangbar is provided with the second spacing block set, and when pedal rotates, pedal offsets with the second spacing block set.
The pedal is provided with the first installation flange.
Second gangbar is provided with the second installation flange.
After said structure, when rotating bar of the present utility model rotates, the first gangbar can be driven to move, first
Lever can drive the second connecting rod to move, and the second connecting rod can drive the second gangbar to move again, so that the second gangbar and the
One gangbar can drive pedal to take exercises simultaneously.Therefore simple in construction, linkage performance is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is Fig. 1 deployed condition schematic diagrames.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment that accompanying drawing provides.
Referring to shown in Fig. 1,2, a kind of linkage structure of extending apparatus, including support bar 1, head rod 2, rotating bar 3,
First gangbar 4, the second gangbar 5, the second connecting rod 6 and pedal 7, one end of the head rod 2 and support bar 1 connect
Connect, rotating bar 3 and one end of support bar 1 are rotatably assorted, and one end of the first gangbar 4 and rotating bar 3 are be hinged, the other end and pedal
7 is be hinged, and one end and the other end of support bar 1 of the second gangbar 5 are hinged, and one end of the other end and pedal 7 is hinged, the second connecting rod
6 one end is be hinged with the first gangbar 4, and the other end and the second gangbar 5 are be hinged.
Referring to shown in Fig. 1,2, in order to limit the motion amplitude of rotating bar 3, and also it is shown in Figure 2, it can also limit
The motion amplitude of first gangbar 4, the support bar 1 are provided with the first spacing block set 11, when rotating bar 3 rotates, rotating bar 3
Offseted with the first spacing block set 11.
In order to limit the motion amplitude of pedal 7, second gangbar 5 is provided with the second spacing block set 51, when 7 turns of pedal
When dynamic, pedal 7 offsets with the second spacing block set 51.
Referring to shown in Fig. 1,2, the pedal 7 is provided with the first installation flange 71.First installation flange 71 can install sand
Pedal parts are sent out, second gangbar 5 is provided with the second installation flange 52.Second installation flange 52 can install other sofas
Part.
Referring to shown in Fig. 1,2, when the utility model is installed, head rod 2 is connected with one end of support bar 1, first
Connecting rod 2 is used for the linkage part for connecting other extending apparatus, and rotating bar 3 and one end of support bar 1 are rotatably assorted, the first linkage
One end of bar 4 is be hinged with rotating bar 3, and the other end is be hinged with pedal 7, and one end and the other end of support bar 1 of the second gangbar 5 are cut with scissors
Connect, one end of the other end and pedal 7 is hinged, and one end of the second connecting rod 6 is be hinged with the first gangbar 4, the other end and second
Lever 5 is be hinged.After installation, when rotating bar 3 rotates, the first gangbar 4 can be driven to move, the first gangbar 4 can drive
Second connecting rod 6 is moved, and the second connecting rod 6 can drive the second gangbar 5 to move again, so as to the second gangbar 5 and the first linkage
Bar 4 can drive pedal 7 to take exercises simultaneously.Therefore simple in construction, linkage performance is good.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
