Embodiment
Be described in detail referring to the drawings with reference to embodiment, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in figures 1-8, the quick rotation locking mechanism of one kind of the utility model, including be linked in sequence stent 1, run through
The shaft 8 of stent 1, the square toes 2 for accommodating shaft 8, the movable sleeve 4 and adapter sleeve 6 for accommodating square toes 2, and handle 7, the branch
Offer two opposite through holes on frame 1, the radial section of the movable sleeve 4 is rectangle, two through holes on the stent 1
Spacing is between the bond length and long edge lengths of the radial section of movable sleeve 4, external screw thread and handle on the square toes 2
7 internal thread connection is fixed, and the external screw thread of handle 7 is connected fixation with the internal thread in adapter sleeve 6.
Further, as shown in figs 6-8, the movable sleeve 4 be equipped with installation cushion rubber 5 the second cavity 11, cushion rubber 5 with
Adapter sleeve 6 is connected for transition, and the friction coefficient of wherein cushion rubber 5 is larger so that adapter sleeve 6 can pass through the friction of cushion rubber 5
Power drives movable sleeve 4 to rotate, and after movable sleeve 4 rotates certain angle, stent 1 can rotate certain angle along shaft 8, i.e.,
Power and energy.
Further, the movable sleeve 4 is equipped with the first cavity 10, and the angle of the first cavity 10 is 90 degree, on square toes 2
Perforate equipped with holding locating pin 9, the head captured of positioning pin 9 is in the first cavity 10.Due to 9 and first cavity 10 of positioning pin
It is spacing, movable sleeve 4 can only be rotated by 90 °, and 0 degree of when is restraint location, be conversion position at 90 degree, left-handed adapter sleeve 6, which drives, lives
When dynamic set 4 enters 90 degree, power and energy can be carried out, 6 dextrorotation of adapter sleeve causes movable sleeve 4 to automatically return to 0 degree, at this time can be into
Row fastening.Built-in 5 main function of cushion rubber is to drive movable sleeve 4, when adapter sleeve 6 drives 4 left rotation and right rotation of movable sleeve to 0 degree or 90 degree
When, movable sleeve 4 will stop rotating, and adapter sleeve 6 can continue to rotate, and reach preferable elastic effect.
Further, intermediate plate 3, the size of intermediate plate 3 and the size phase of movable sleeve 4 are connected with the movable sleeve 4
Coordinate, above-mentioned shaft 8 is the assembly of bolts and nuts.
The length and width size for being technically characterized in that 4 radial section of movable sleeve of the utility model device, and stent 1
The spacing of upper two through holes, the dimensional fits relation of this three, wherein, movable sleeve 4, which rotates forward 90 degree, can be placed in stent 1
Two through holes between, as shown in figure 3, movable sleeve 4 reversely rotate 90 degree then can be with the bottom plane-plane contact of stent 1.
