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 leg, comprises fixed mount 1, pillar stiffener 2 and sole 3, and fixed mount 1 is positioned at the top of pillar stiffener 2 and fixes with pillar stiffener 2.As shown in accompanying drawing 2, accompanying drawing 3, the bottom of pillar stiffener 2 is provided with a jointed shaft 4, jointed shaft 4 is radially across pillar stiffener 2, two parallel riser 3-1 are provided with on sole surface, pillar stiffener 2 bottom is between two riser 3-1, the two ends of jointed shaft 4 pass perpendicularly through riser 3-1 respectively, and sole 3 and two parallel riser 3-1 freely can rotate around jointed shaft 4.
After adopting said structure, sole 3 is free to rotate, when the bearing surface that sole 3 contacts is inclined, can realize the Full connected between sole 3 ground and bearing surface by the rotation of sole 3, the stress deformation preventing the localized contact due to sole 3 bottom surface from causing damages.
As shown in accompanying drawing 2 and accompanying drawing 3, for adapting to the differing heights of contact surface, in the present embodiment, pillar stiffener 2 makes height adjustable structure.Pillar stiffener 2 is formed by interior tube body 2-1 and outer tube body 2-2 fit, and interior tube body 2-1 is provided with some radial direction through hole 2-3, is provided with a fixed orifice 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 fixes through fixed orifice 2-4 and radial direction through hole 2-3 by one set pin 2-5, corresponding with fixed orifice 2-4 thus play and adjust whole pillar stiffener 2 object highly by the radial direction through hole 2-3 of diverse location on adjustment interior tube body 2-1.
As shown in accompanying drawing 2 and accompanying drawing 3, when adopting height-adjustable pillar stiffener, fixedly referring between outer tube body 2-2 and fixed mount 1 above pillar stiffener 2 and between fixed mount 1 is fixing, radially across pillar stiffener 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 bearing surface differs from ten thousand changes, although adopt turnable foot structure can solve the problem of sole and bearing surface localized contact, but when the shape of bearing surface is the slope of a larger angle, because pillar stiffener is in plumbness, although sole angle can be consistent with slope, but under gravity, be difficult to play stable support effect, good solution is the certain angle that simultaneously tilted by pillar stiffener, makes to form vertical support state between pillar stiffener and bearing 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 pillar stiffener 2 and fixed mount 1 is hinged fixing, and in this embodiment, fixed mount 1 is an inverted U support body, and pillar stiffener 2 top is between inverted U support body, and the second jointed shaft 5 is through inverted U support body and pillar stiffener 2.
For the rotational angle between fixed pedestal post 2 and fixed mount 1, as shown in accompanying drawing 2 and accompanying drawing 3, the top of pillar stiffener 2 is with circular dowel disc 6, it is inner and parallel with inverted U support body sidewall that circular dowel disc 6 is positioned at inverted U support body, uniform some knock hole 6-1 at the edge of circular dowel disc, the inverted U support body sidewall of circular dowel disc side is provided with positioning through hole.As shown in Figure 2, circular dowel disc is fixed with inverted U support body (the inverted U support body side-walls that in accompanying drawing 2, locating dowel pin 7 is corresponding has positioning through hole) through positioning through hole and knock hole by a locating dowel pin 7.After adopting this structure, by the knock hole 6-1 angular adjustment that can realize pillar stiffener 2 and fixed mount 1 between corresponding to positioning through hole adjusting diverse location on circular dowel disc 6.
For further facilitating the angle between adjustment pillar stiffener 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 locating dowel pin 7 is positioned in the middle part of handle 8, guide pillar 9 is respectively equipped with in locating dowel pin both sides, inverted U support body lateral wall is provided with the guide pin bushing 10 corresponding with guide pillar 9, and it is inner that guide pillar 9 is positioned at guide pin bushing 10, is provided with the back-moving spring (attached not shown) be connected with guide pillar bottom guide pin bushing.After adopting this structure, due to the effect of back-moving spring, without under the effect of external force, position between pillar stiffener 2 and fixed mount 1 is pinned at positioning through hole and knock hole 6-1 inside by locating dowel pin 7, when needing to adjust the angle between pillar stiffener 2 and fixed mount 1, handle 8 is outwards exerted a force, locating dowel pin 7 and guide pillar 9 move together laterally, locating dowel pin 7 departs from knock hole 6-1, angle now namely between adjustable pillar stiffener 2 and fixed mount 1, when adjusting to proper angle, unclamp handle 8, under the effect of back-moving spring, locating dowel pin 7 enters the inner locking realized between pillar stiffener 2 and fixed mount 1 of knock hole 6-1 again.
In the present embodiment, this bracing frame leg is mainly used on drawing-type caravan, and current drawing-type caravan comprises vehicle frame, and vehicle frame front end is provided with drawing head, fixes the bracing frame leg provided in the present embodiment in vehicle frame front end.
Apply widely as one, this bracing frame leg can be widely used in any bracing or strutting arrangement, as long as install the bracing frame leg that the present embodiment provides below the bearing surface of bracing or strutting arrangement.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technology people of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; 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 all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
