Embodiment
Below in conjunction with accompanying drawing, the utility model bus that stretches is patched crane span structure and is described in further detail.
As shown in FIG. 1 to 3, the utility model bus that stretches patches crane span structure, and bag is inserted: inner sleeve box 1 and be arranged on the outer package box 3 in outside of inner sleeve box 1.The side of outer package box 3 is provided with chute 4, and screw 5 is fixedly installed in chute 4, and the gear 6 playing end matches with the tooth bar 2 on inner sleeve box 1 side.By the rotation of screw 5, the rotation of driven wheel 6 is also with carry-over bar 2 and inner sleeve to move in outer tube, and the difference of length as required, screw 5 can move with the demand adapting to different size in chute 4.
After determining length, a bolt is inserted in the fixing hole 8 of chute 4 both sides from the patchhole 7 screw 5, realizes the effect of locking.After finishing using, only need bolt to extract, inner sleeve will return to initial position under the effect recovering spring (not shown), convenient, laborsaving.
Connector is arranged on the opening part of inner sleeve box 1, and support bar 9 is connected on the both sides inwall of inner sleeve box 1 opening part, and control lever 10 is mutually vertical with it to be connected.Patch sheet to be made up of lock arm 13, linking arm 14 and the fixed arm 15 connected successively from beginning to end, the lock arm 13 patching sheet afterbody is arranged on support bar 9 by a locking piece 17 with bayonet socket, and the front end of control lever 10 is stretched into two panels and to be patched between sheet and to fix with guide rod 11.And the two ends of guide rod 11 are stretched out through the guide hole (not shown) on linking arm 14 and patched outside sheet, overlap at the end of guide rod 11 has spring 12 simultaneously simultaneously, makes to patch sheet and forms inside resilience force.
In addition, lock arm 13, linking arm 14 and fixed arm 15 are the design of median rise, are also the elasticity in order to strengthen patching sheet further.
And be provided with in the inner side of lock arm 13 and fixed arm 15 boss 16 arranged in opposite directions, the chucking power patching sheet can be ensured.
During use, the opening part of fixed contact from fixed arm 15 is inserted, clamps fixed contact by the boss 16 inside fixed arm 15.When needs adjust time, the afterbody of control lever 10 can be held, make to patch sheet and rotate around support bar, to adapt to different angles.
The utility model bus that stretches patches the rotation of crane span structure by screw, the rotation of driven wheel is also with carry-over bar and inner sleeve to move in outer tube, the difference of length as required, screw can move the demand to adapt to different size in chute, after determining length, a bolt is inserted in fixing hole from the patchhole screw, realizes the effect of locking.After finishing using, only need bolt to extract, inner sleeve will return to initial position under the effect recovering spring, convenient, laborsaving.
And connector can make to patch sheet by the operation of control lever and rotates in certain scope around support bar, to adapt to different insertion angles.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the scope of the application.
