The specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Consult shown in Fig. 1 to Fig. 3, the large helical pitch king-rod of the tent segmentation nut type height adjustment mechanism that the present invention discloses, comprise outer bar 1, interior bar 2, mount pad 3, adjusting nut 4, adjusting screw(rod) 5 and crank 6.
Outer bar 1 is arranged in mount pad 3, and interior bar 2 is socketed in outer bar 1.In the present embodiment, mount pad 3 is and lower four pipeline connectors of the collapsible push rod assembly of tent (not shown) pivot joint, uses existing lower four pipeline connectors and saves manufacturing costs, certainly mount pad 3 can be set separately.
Adjusting nut 4 is arranged in interior bar 2, relative fixing with interior bar 2, i.e., during adjusting nut 4 motion, interior bar 2 moves thereupon.Adjusting screw(rod) 5 one ends and adjusting nut 4 are spirally connected, other end socket crank 6, and crank 6 rotates adjusting screw(rod) 5 is rotated, and drives adjusting nut 4 and does elevating movement.In the present embodiment, crank 6 is comprised of sleeve 61, connection handle 62 and swing handle 63 3 parts, and connection handle 62 1 ends are connected with sleeve 61, and the other end is connected with swing handle 63.
For saving material, and cost-saving, the present invention also comprises connecting rod 7, and connecting rod 7 one ends are fixedly connected with adjusting screw(rod) 5, and the other end is connected with crank 6, and crank 6 rotates connecting rod 7 is rotated, and then drives adjusting screw(rod) 5 rotations.
The present invention also comprises self-locking device 8, and self-locking device 8 comprises plug 82, rotary handle 83 and back-moving spring 84 in supporting seat 81, rotation.
Supporting seat 81 is embedded in outer bar, and fixing with mount pad 3 from the side, is provided with the tooth top (not shown) on supporting seat 81.
In rotation, plug 82 is connected to form the adjusting screw(rod) group without relative motion with connecting rod 7 lower ends by rivet.In rotation, plug 82 arranges the external tooth (not shown), and the internal tooth (not shown) is set in crank 6 sleeves 61, and in rotating, plug 82 is socketed in crank 6 sleeves 61, sleeve 61 internal tooths and the interior plug 82 external tooth engagements of rotation.
Rotary handle 83 rotatably is arranged in rotation on plug 82, and in the present embodiment, in rotation, plug is embedded with in 82 metal threadedly, and is embedded with metal screw on rotary handle 83, metal screw screw in metal threaded in.
Crank 6 sleeve 61 upper ends form the teeth groove 611 corresponding with tooth top, and lower end abutment is on rotary handle 83.During the engagement of the tooth top of the teeth groove of sleeve 61 and supporting seat 81, crank 6 is fixing, and during the tooth top disengagement of the teeth groove of cylinder 61 and supporting seat 81, crank 6 is rotatable.Certainly, also can on supporting seat 81, teeth groove be set, and tooth top is set on sleeve 61, can by crank 6 positioning instants as long as realize teeth groove and tooth top to mesh.
