Description
Technical field
The utility model belongs to umbrella field, specifically discloses a kind of multi-fold umbrella opening elastic intensifier.
Background technology
Umbrella in being in normal life conventional instrument, especially automatic umbrella folding and unfolding because easy to use and very popular.Conventional automatic umbrella folding and unfolding generally includes: the umbrella frame bracket assembly that is provided with umbrella colsing spring, inside be provided with the middle rod of deployment spring, be installed in the lower nest that the upper nest of middle excellent upper end and slip cap are contained in middle rod, be arranged on the automatic open-close control device in handle of umbrella and middle rod, for holding the drag-line that lower nest does not glide in deployed condition, this drag-line is surrounded on the assembly pulley that is located at nest and lower nest, and nest is fixed in its one end, and the other end is fixed on automatic open-close control device through middle rod.When gear is pressed parachute-opening button, in middle rod, compressed deployment spring extends, retracting spring power, and umbrella is opened gradually, and owing to there being the position-limiting action of drag-line, lower nest position is relatively fixing, and umbrella is in open mode.The umbrella of open mode is pressed while closing one's umbrella button, and drag-line is released, and lower nest loses support, and umbrella cover is automatic folding under the effect of umbrella colsing spring, but now, rod is can auto-folder, needs staff just can fold up to pressing down middle rod.
In the time of complete umbrella closing state, umbrella shaft is compressed.Because deployment spring need to be arranged in the middle rod after being retracted, in the time that the broken number of umbrella increases, the middle rod after contraction can be shorter, leaves the limited space of deployment spring for, so in umbrellas more than current three foldings, seldom have automatic open-close elastic force stiffening device.
Utility model content
A kind of multi-fold umbrella opening elastic intensifier that the utility model provides for above-mentioned weak point.Can in the confined space, provide the opening force of umbrella to strengthen, make the automatic open-close application of installation of umbrella in multi-fold umbrella.
The utility model is to realize like this, a kind of multi-fold umbrella opening elastic intensifier, comprise inner tube, middle pipe, outer tube, interior gear pipe; umbrella handle, is characterized in that the outer sheathed pogo barrel of interior gear pipe, and it is circular that pogo barrel is; pogo barrel upper end inner cylinder arranges the first spring block face, and lower end outer cylinder arranges the second spring block face; The first deployment spring is sheathed on outside interior gear pipe, and in pogo barrel, the first deployment spring is between pogo barrel and umbrella handle, and the first deployment spring external diameter is greater than the first spring block face internal orifice dimension; The second deployment spring is sheathed on outside pogo barrel, and in outer tube, the second deployment spring is between pogo barrel and gear pipe holder, and the second deployment spring internal diameter is less than the second spring block face external diameter.
Multi-fold umbrella opening elastic intensifier of the present utility model, pogo barrel length is less than keeps off the distance between Yu Zhongguan upper end, pipe holder lower end while closing one's umbrella.
Meanwhile, in pogo barrel, the first spring block face replaces with and is arranged in the inner cylinder of pogo barrel upper end, stops the first bump that flicks umbrella spring and skid off pogo barrel.In pogo barrel, the second spring block face replaces with on the outer cylinder of pogo barrel lower end, stops the second deployment spring to skid off the bump of pogo barrel.
Two spring block faces in pogo barrel can be transformed to bump individually or simultaneously.
Multi-fold umbrella opening elastic intensifier of the present utility model, by pogo barrel is set, deployment spring is divided into two sections, two sections of springs be arranged on respectively pogo barrel inside and outside, deployment spring is partly overlapped in the confined space, effectively increased deployment spring working deformation length.In multi-fold umbrella, although middle rod is shorter, install after automatic open-close device, enough deploying forces can be provided equally, make multi-fold umbrella realize automatic open-close function.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail; but the utility model is not limited to following embodiment; any change of making in the present embodiment principle or replacement scheme, all fall among the claimed scope of the utility model.
Arrive Fig. 6 in conjunction with Fig. 1, a kind of multi-fold umbrella opening elastic intensifier, comprise inner tube 2, middle pipe 3, outer tube 4, interior gear pipe 6; umbrella handle 1, is characterized in that interior gear manages 6 outer sheathed pogo barrels 8, and pogo barrel 8 is circular; pogo barrel 8 upper end inner cylinder arrange the first spring block face 82, and lower end outer cylinder arranges the second spring block face 81; The first deployment spring 5 is sheathed on outside interior gear pipe 6, and in pogo barrel 8, the first deployment spring 5 is between pogo barrel 8 and umbrella handle 1, and the first deployment spring 5 external diameters are greater than the first spring block face 82 internal orifice dimensions; The second deployment spring 7 is sheathed on outside pogo barrel 8, and in outer tube 4, the second deployment spring 7 is between pogo barrel 8 and gear pipe holder 9, and the second deployment spring 7 internal diameters are less than the second spring block face 81 external diameters.
Multi-fold umbrella opening elastic intensifier of the present utility model, pogo barrel 8 length are less than keeps off the distance between pipe holder 9 lower ends and middle pipe 3 upper ends while closing one's umbrella.
Meanwhile, in pogo barrel 8, the first spring block face 82 replaces with and is arranged in pogo barrel 8 upper end inner cylinder, stops the first deployment spring 5 to skid off the bump of pogo barrel 8.In pogo barrel 8, the second spring block face 81 replaces with on pogo barrel 8 lower end outer cylinders, stops the second deployment spring 7 to skid off the bump of pogo barrel 8.
Two spring block faces in pogo barrel 8 can be transformed to bump individually or simultaneously.
After umbrella is packed up completely, middle pipe 3 and inner tube 2 all receive in outer tube 4, and pogo barrel 8 is between gear pipe holder 9 lower ends and middle pipe 3 upper ends.The first deployment spring 5 is positioned at pogo barrel 8, the second deployment springs 7 and is positioned at outside pogo barrel 8, owing to there being pogo barrel 8 to act on, the first deployment spring 5 and the second deployment spring 7 is partly overlapped, and has increased the number of effective coils of spring.Identical installing space, has adopted pogo barrel 8, has increased the work shift distance of spring.
