Furthermore, backing plates are arranged on two sides of the supporting legs respectively.
Further, backing plate one end articulates on the supporting leg, and the other end is provided with the buckle, is provided with the draw-in groove of holding buckle on the supporting leg.
Further, the supporting leg is extending structure, including interconnect's telescopic sleeve and telescopic link all open equidistant through-hole on telescopic sleeve and the telescopic link, adjust the back and connect fixedly through the fixed pin.
Furthermore, a fine adjustment mechanism is arranged between the supporting leg and the connecting plate.
Furthermore, fine setting mechanism include with the connecting plate be connected have the external screw thread the connecting rod with flexible cover, the one end that flexible cover and connecting rod are connected has rather than the external screw thread complex internal thread, the connecting rod with flexible cover passes through threaded connection, finely tunes.
Furthermore, the connecting plate is movably connected with the horizontal base.
The utility model has the beneficial effects that:
1. according to the utility model, the foldable base plate is arranged at the bottom of the supporting foot frame, so that when the ground is rainy or loose, the base plate folded at the bottom of the foot frame is opened, and the contact area of the foot frame is increased.
2. The utility model can arrange backing plates on two sides of the supporting leg respectively to enlarge the contact area with the ground. And the backing plate is provided with a buckle, and the landing leg is provided with a clamping groove for accommodating the buckle, so that the storage and the opening are convenient.
3. The supporting leg is provided with a coarse adjustment structure and a fine adjustment structure, wherein the coarse adjustment structure is formed by a telescopic sleeve and a telescopic rod which are connected with each other, through holes with equal intervals are formed in the telescopic sleeve and the telescopic rod, and the telescopic sleeve and the telescopic rod are connected and fixed through fixing pins after adjustment; the fine adjustment is arranged between the supporting leg and the connecting plate and is realized by connecting the connecting rod with external threads with the telescopic sleeve through threads.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. the device comprises a horizontal base, 2 parts of a connecting plate, 3 parts of a connecting rod, 4 parts of a telescopic sleeve, 5 parts of a telescopic rod, 6 parts of a fixing pin, 7 parts of a base plate and 8 parts of a clamping groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example (b): the utility model relates to a foot rest based on loose ground, which comprises a horizontal base 1, telescopic supporting legs and base plates 7, wherein the horizontal base 1 is a triangular prism plate, the number of the three supporting legs is equal to that of the three side surfaces of the triangular prism plate, the three supporting legs are respectively connected with the triangular prism plate through connecting plates 2, the bottom ends of the three supporting legs are respectively provided with a foldable base plate 7, and the foldable base plates 7 are used for opening the foldable base plates 7 to assist supporting legs in supporting when the ground is loosened.
Further, backing plates 7 are respectively arranged on two sides of the supporting legs.
Further, one end of the base plate 7 is hinged to the supporting leg, the other end of the base plate is provided with a buckle, and a clamping groove 8 for containing the buckle is formed in the supporting leg. Be provided with the spring in the buckle, through pressing the buckle, backing plate 7 of expansion bracket lower extreme is popped out, has increased the area of contact of foot rest and ground.
Further, the supporting leg is extending structure, including interconnect's telescopic sleeve 4 and telescopic link 5 all open equidistant through-hole on telescopic sleeve 4 and the telescopic link 5, adjust the back and connect fixedly through fixed pin 6 to realize the adjustment by a wide margin of foot rest length.
Further, a fine adjustment mechanism is arranged between the supporting leg and the connecting plate 2.
Further, fine-tuning includes the connecting rod 3 that has the external screw thread and be connected with connecting plate 2 telescopic sleeve 4, the one end that telescopic sleeve 4 and connecting rod 3 are connected has rather than the internal thread of external screw thread complex, connecting rod 3 with telescopic sleeve 4 passes through threaded connection, finely tunes.
