In order to make those skilled in the art person understand scheme provided by the invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See the structural representation that Fig. 4, Fig. 4 are skeleton provided by the invention.
As described in Figure 4, in a kind of detailed description of the invention, skeleton provided by the invention comprises main supporting rod 1, upper fixing element 2, main center-pole 3, pushes away handle 4, middle contact pin 7 and sub-strut bar 8, main supporting rod 1 is hinged with sub-strut bar 8 by middle contact pin 7, the upper end of main center-pole 3 is fixed in upper fixing element 2, push away handle 4 hinged with the end of sub-strut bar 8, push away handle 4 coaxial with main center-pole 3, and its diameter of bore is greater than the diameter of main center-pole 3.
View when being skeleton provided by the invention storage see Fig. 5, Fig. 5.
In Fig. 5, when above-mentioned skeleton is in receiving state, pushes away handle 4 and be separated with main center-pole 3, and be in lower position, now, main supporting rod 1 and main center-pole 3 and sub-strut bar 8 are with main center-pole 3 and connect subparallel state, and this skeleton is carried more for convenience.
See Fig. 6, Fig. 6 be skeleton provided by the invention strut time view.
In figure 6, when skeleton provided by the present invention needs to strut, push away handle 4 and make it move up and be socketed with main center-pole 3, continue upwards to push away, until in the triangle that forms of main center-pole 3, main supporting rod 1 and sub-strut bar 8, the interior angle be made up of sub-strut bar 8 and main center-pole 3 is obtuse angle.In this state, because the fabric on skeleton is to the constraint effect of main supporting rod 1, the direction of sub-strut bar 8 to the support force pushing away handle 4 is contrary with the direction of traditional skeleton power, even if so lose external force, sub-strut bar 8 also will provide thrust for pushing away handle 4, make to push away handle 4 to contact with the lower surface of upper fixing element 2, and remain on this state, thus complete skeleton strut process.
Obviously, this structure interaction force that make use of between skeletal internal structure reaches the object keeping skeleton to strut, and does not need supplementary structure, and number of parts is few, and easy to operate.
Can find out according to foregoing description, skeleton provided by the invention makes upper fixing element 2 and pushes away handle 4 and directly contact, the distance shortening upper fixing element 2 and push away between handle 4, and then shortened the length of main center-pole 3, reduce the space shared by skeleton, increase the usage space of skeletal internal, improve its practicality.
In Fig. 4, in order to make skeleton provided by the invention safer in use, this skeleton also comprises connecting rod 13 and hook 14, and connecting rod 13 is installed on upper fixing element 2, and hook 14 is connected with connecting rod 13.After this skeleton struts, be hooked in by hook 14 in the hole that pushes away and handle 4 is arranged, apply certain pulling force to this skeleton, even if there are dynamic or other situations of wind, skeleton also can not cave in, and makes whole skeleton more reliable, improves the safety in utilization of skeleton.
In specific implementation process, usually needed to add auxiliary support mechanism to realize the function such as shielded from sunlight or wind and rain on the limit of umbrella or paulin by the umbrella of above-mentioned skeletal support or paulin, and some occasion needs to arrange supporting mechanism in the centre of umbrella or paulin, so in order to enable above-mentioned skeleton more convenient be applied to this occasion, this skeleton is also provided with sub-center bar 5, sub-center bar 5 and main center-pole 3 are on same axis, and both are flexibly connected by screw thread.Now push away handle 4 can directly be enclosed within sub-center bar 5, so when pushing away handle 4, sub-center bar 5 is equivalent to guide rod, and location more for convenience.Obviously, be connected to by sub-center bar 5 on main center-pole 3 and can realize supporting, after backing out sub-center bar 5, this skeleton just can be used for the occasion of other supporting form.
When above-mentioned main center-pole 3 and sub-center bar 5 adopt and be threaded, main center-pole 3 is generally solid, and intensity is higher.
In a specific embodiment, the flexible connection of main center-pole 3 and sub-center bar 5 also realizes by stretching structure, namely the diameter of main center-pole 3 is greater than the diameter of sub-center bar 5, when needing sub-center bar 5 to support, sub-center bar 5 is extracted out, sub-center bar 5 can be pushed in main center-pole 3 when not needing.Locking between main center-pole 3 and sub-center bar 5 adopts conventional telescoping mechanism lock mode just can.Visible adopting operates more in this way, but due to main center-pole 3 be hollow, so higher to the diametric requirements of main center-pole 3.
