Utility model content
It is a kind of by regulating height to increase the large helical pitch king-rod of the tent segmentation nut type height adjustment mechanism of tent inner space that the purpose of this utility model is to provide.
For reaching above-mentioned purpose, solution of the present utility model is:
The large helical pitch king-rod of a segmentation nut type height adjustment mechanism, comprises outer bar, interior bar, adjusting screw(rod), adjusting nut, tumbler and positioner; Outer bar is arranged in positioner, and interior bar is socketed in outer bar; Adjusting nut is arranged in interior bar, and adjusting screw(rod) and adjusting nut are spirally connected, and is connected with tumbler; Tumbler rotates adjusting screw(rod) is rotated, and drive adjusting nut to do elevating movement, and positioner makes tumbler in rotatable state or stationary state.
Further, tumbler, by regulating handle and regulating rotating disk to form, regulates handle one end to be articulated in and regulates on rotating disk, and the other end arranges turning handle.
Further, regulating rotary dish forms accommodating cavity, and upset regulates handle and is placed in accommodating cavity.
Further, positioner is and lower four pipeline connectors of collapsible push rod assembly pivot joint, and lower four pipeline connectors are by brace and the pivot joint of collapsible push rod assembly, upset adjusting handle and turning handle is inserted between adjacent brace and tumbler is fixed.
Further, also comprise connecting rod, connecting rod one end is connected with adjusting screw(rod), and the other end is connected with tumbler.
Further, also comprise dome, dome is arranged on interior bar upper end.
Further, also comprise spacing plug, spacing plug is arranged on interior bar bottom.
Further, adjusting screw(rod) divides the section of pluralizing adjusting screw(rod) unit, and adjacent adjusting screw(rod) connects by spacer between unit, and accordingly, adjusting nut is divided into the plural number section adjusting nut unit consistent with adjusting screw(rod) unit number.
Adopt after such scheme, the utility model adjusting screw(rod) is connected with tumbler, when tumbler rotates towards a direction (as clockwise), drive adjusting screw(rod) rotates, adjusting nut is moved upward, and in driving, bar moves upward in bar outside, thereby tent has been shored, increase the paulin heights of roofs of tent, reduce the possibility of top ponding.Now, positioner makes tumbler in stationary state, and tumbler no longer rotates.When pack up on tent top, positioner makes tumbler in rotatable state, and tumbler is (as counterclockwise) rotation to another way, and adjusting nut is moved downward, and in driving, bar moves downward in bar outside, and tent top is packed up, and portably uses conveniently.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Consult shown in Fig. 1 to Fig. 6, the large helical pitch king-rod of a kind of tent segmentation nut type height adjustment mechanism 100 that the utility model discloses, comprises outer bar 1, interior bar 2, adjusting nut 3, adjusting screw(rod) 4, positioner 5 and tumbler 6.
Outer bar 1 is arranged in positioner 5, and interior bar 2 is socketed in outer bar.Adjusting nut 3 is arranged in interior bar 2, relative fixing with interior bar 2, i.e., during adjusting nut 3 motion, interior bar 2 moves thereupon, and adjusting screw(rod) 4 is spirally connected with adjusting nut 3, and adjusting screw(rod) 4 is connected with tumbler 6.
Tumbler 6 rotates adjusting screw(rod) 4 is rotated, and then makes adjusting nut 3 do elevating movement, and in adjusting nut 3 drives, bar 2 stretches in bar 1 outside.Positioner 5 can make tumbler 6 in movable state or stationary state.
As shown in Figures 7 and 8, in the present embodiment, tumbler 6, by regulating handle 61 and regulating rotating disk 62 to form, regulates handle 61 one end to be articulated in and regulates on rotating disk 62, and the other end arranges turning handle 611.Regulate rotating disk 62 to form accommodating cavity, upset regulates after handle 61, can will regulate handle 61 to be placed in accommodating cavity.Tumbler 6 can be other structure, as long as realize, rotates.
As shown in FIG. 9 and 10, in the present embodiment, positioner 5 is lower four pipeline connectors 51 with collapsible push rod assembly 10 pivot joints, lower four pipeline connectors 51 are by brace 511 and collapsible push rod assembly 10 pivot joints, upset regulates handle 61 turning handle 611 can be inserted between adjacent brace 511 and tumbler 6 is fixing, makes the no longer lifting of the utility model king-rod height adjustment mechanism.Positioner 5 can be other structure, as long as realize, makes tumbler 6 in movable state or stationary state.
The utility model is by regulating the turning handle 611 on handle 61 to extract down between the adjacent brace 511 of four pipeline connectors 51, make to regulate handle 61 and regulate rotating disk 62 to rotate, drive adjusting screw(rod) 4 to rotate, make adjusting nut 3 do elevating movement, in driving, bar 2 is done elevating movement in bar 1 outside.And while regulating turning handle 611 on handle 61 to insert between the adjacent brace 511 of lower four pipeline connectors 51, turning handle 611 is limited between adjacent brace 511, makes to regulate handle 61 and regulates rotating disk 62 to rotate, and plays the effect of location.In the present embodiment, use existing lower four pipeline connectors 51 and realize position-limiting action, save production cost, and simple in structure.
As shown in Fig. 3 and Fig. 5, for saving material, and it is cost-saving, the 4 minutes section of pluralizing adjusting screw(rod) unit 41 of adjusting screw(rod), accordingly, adjusting nut 3 is divided into the plural number section adjusting nut unit 31 consistent with adjusting screw(rod) unit 41 numbers, between adjacent two adjusting nut unit 31, by spacer 42, connects.
For further saving material, and cost-saving, the utility model also comprises connecting rod 7, and connecting rod 7 one end are connected with adjusting screw(rod) unit, bottom 41, and the other end is connected with the adjusting rotating disk 62 of tumbler 6.
For preventing that interior bar 2 from puncturing tent cloth and preventing that interior bar 2 from excessively inside contracting, the utility model also arranges dome 8, and dome 8 is arranged on interior bar 2 upper ends.Meanwhile, prevent that interior bar 2 from excessively rising, the socket of disengaging and outer bar 1, the utility model also comprises spacing plug 9, spacing plug 9 is arranged on interior bar 2 bottoms.
The nut group that the utility model forms by several regulation of series nut unit 31 regulates height to increase tent top height, reduces the possibility of rainy day tarpaulin ponding, extends the application life of tent.Nut group owing to having adopted several regulation of series nut unit 31 to form, has greatly reduced cost, has improved the feasibility of the industrialization volume production of this structure.
The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
