Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in accompanying drawing 2, accompanying drawing 3, a kind of bracing frame lower limb, including fixed mount 1, support column 2 and sole 3, fixed mount 1 is positioned at the top of support column 2 and fixes with support column 2.As shown in accompanying drawing 2, accompanying drawing 3, the bottom of support column 2 is provided with a jointed shaft 4, jointed shaft 4 is radially across support column 2, two parallel riser 3-1 it are provided with on sole surface, support column 2 bottom is between two riser 3-1, the two ends of jointed shaft 4 are respectively perpendicular through riser 3-1, and sole 3 and two parallel riser 3-1 can be freely rotatable around jointed shaft 4.
After adopting said structure, sole 3 is free to rotate, when the supporting surface that sole 3 contacts is inclined, the Full connected between sole 3 ground and supporting surface can be realized by the rotation of sole 3, it is prevented that the stress deformation caused due to the localized contact of sole 3 bottom surface damages.
As shown in accompanying drawing 2 and accompanying drawing 3, for adapting to the differing heights of contact surface, in the present embodiment, support column 2 makes height adjustable structure.Support column 2 is formed by interior tube body 2-1 and outer tube body 2-2 fit, is provided with some radial direction through hole 2-3 on interior tube body 2-1, is provided with a fixing hole 2-4 on the top of outer tube body 2-2.As shown in Figure 2, interior tube body 2-1 and outer tube body 2-2 is fixed by one steady pin 2-5 through fixing hole 2-4 and radial direction through hole 2-3, corresponding with fixing hole 2-4 thus playing the purpose adjusting whole support column 2 height by adjusting the radial direction through hole 2-3 of diverse location on interior tube body 2-1.
As shown in accompanying drawing 2 and accompanying drawing 3, when adopting height-adjustable support column, fixing the referring to above support column 2 and between fixed mount 1 is fixed between outer tube body 2-2 and fixed mount 1, radially across support column 2, jointed shaft 4 refers to that jointed shaft 4 is radially across interior tube body 2-1 bottom.
Due in actual application, the shape thousand of supporting surface differs from ten thousand changes, although adopting the problem that turnable foot structure can solve sole and supporting surface localized contact, but when the slope being shaped as a larger angle of supporting surface, owing to support column is in plumbness, although sole angle can keep consistent with slope, but under gravity, it is difficult to play stable support effect, good solution is that support column tilts certain angle simultaneously, makes to form vertical support state between support column and supporting surface to ensure stable support.
For realizing technique scheme, have employed having structure in the present embodiment.As shown in accompanying drawing 2 and accompanying drawing 3, the fixing employing between support column 2 and fixed mount 1 is hinged fixing, and in this embodiment, fixed mount 1 is an inverted U support body, and support column 2 top is between inverted U support body, and the second jointed shaft 5 passes inverted U support body and support column 2.
For the rotational angle between fixing support column 2 and fixed mount 1, as shown in accompanying drawing 2 and accompanying drawing 3, the top of support column 2 is with circle location dish 6, it is internal and parallel with inverted U support body sidewall that circular location dish 6 is positioned at inverted U support body, at the edge of circle location dish, uniform some location hole 6-1, is provided with positioning through hole on the inverted U support body sidewall of dish side, circle location.As shown in Figure 2, circle is positioned dish fix (the inverted U support body side-walls that in accompanying drawing 2, alignment pin 7 is corresponding has positioning through hole) with inverted U support body through positioning through hole and hole, location by an alignment pin 7.After adopting this structure, by adjusting the location hole 6-1 angle adjustment that can realize support column 2 and fixed mount 1 between corresponding to positioning through hole of diverse location on circular location dish 6.
For further facilitating the angle adjusted between support column 2 and fixed mount 1, as shown in Figure 2, the lateral wall of inverted U support body being provided with positioning through hole side is provided with handle 8, aforesaid alignment pin 7 is positioned in the middle part of handle 8, it is respectively provided on two sides with guide pillar 9 at alignment pin, inverted U support body lateral wall is provided with the guide pin bushing 10 corresponding with guide pillar 9, and it is internal that guide pillar 9 is positioned at guide pin bushing 10, is provided with the back-moving spring (attached not shown) being connected with guide pillar bottom guide pin bushing.After adopting this structure, effect due to back-moving spring, under the effect without external force, position between support column 2 and fixed mount 1 is pinned by alignment pin 7 inside positioning through hole and location hole 6-1, when needing to adjust the angle between support column 2 and fixed mount 1, handle 8 is outwards exerted a force, alignment pin 7 and guide pillar 9 move together laterally, alignment pin 7 departs from location hole 6-1, it it is now the angle between adjustable support column 2 and fixed mount 1, when adjusting proper angle, unclamp handle 8, under the effect of back-moving spring, alignment pin 7 is again introduced into inside the hole 6-1 of location and realizes the locking between support column 2 and fixed mount 1.
In the present embodiment, this bracing frame lower limb is mainly used on drawing-type caravan, and current drawing-type caravan includes vehicle frame, and vehicle frame front end is provided with drawing head, the bracing frame lower limb provided in the fixing the present embodiment in vehicle frame front end.
As a kind of wider application, this bracing frame lower limb can be widely applied in any support arrangement, if the bracing frame lower limb of the supporting surface the present embodiment offer mounted below at a support arrangement.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology people of the industry it should be recognized that; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
