Brief description of the drawings
Fig. 1 is a kind of structural representation of adjustable type anti-drop bolt proposed by the present invention.
Embodiment
Below, technical scheme is described in detail by specific embodiment.
As shown in figure 1, Fig. 1 is a kind of structural representation of adjustable type anti-drop bolt proposed by the present invention.
Reference picture 1, a kind of adjustable type anti-drop bolt that the embodiment of the present invention proposes, including：Bolt body 1, the spiral shell
Bolt body 1 is provided with from one end-face to its linearly extended grooving in other end end face；The grooving is in the footpath of bolt body 1
Penetrated on to direction, the structure 2 along the insertion direction spacing arrangement of grooving, one end of two structures 2 are provided with inside grooving
The inwall of grooving is flexibly connected respectively, and governor motion is provided between two structures 2；Governor motion includes the first screw rod 3, second
Screw rod 4 and swivel nut 5, first screw rod 3, the thread rotary orientation of the second screw rod 4 are on the contrary, the first screw rod 3, the second screw rod 4 are located at spiral shell
The both ends of set 5, and the first screw rod 3, the second screw rod 4 stretch into the inside of swivel nut 5 close to one end of swivel nut 5 and connected with the screw thread of swivel nut 5
Connecing, the first screw rod 3, second one end of screw rod 4 away from swivel nut 5 are connected with two structures 2 respectively, so that during the rotation of swivel nut 5, can
It can be swung with side of the pushing structure body 2 away from its connection end with the peripheral direction of bolt body 1.
The present invention is that this is so used：After bolt body 1 is through the workpiece for needing to connect, in upper cap nut, pass through
Structure 2 is received in grooving by rotary threaded sleeve 5, then screws in nut from the initiating terminal of grooving to its terminal extreme direction direction, and
Nut fixation after, again lead to rotary threaded sleeve 5, with promote peripheral direction from two structures 2 to bolt body 1 open, with
The unscrewing end of nut forms the stop position that external diameter is more than nut endoporus.
From the foregoing, it will be observed that the present invention by setting grooving on bolt body 1, sets two insertions along grooving in grooving
The structure 2 of direction spacing arrangement, sets governor motion between two structures 2, and makes one end difference of two structures 2
The inwall of grooving is flexibly connected, and adjustment structure is included the first screw rod 3, the second screw rod 4 and swivel nut 5, is made the first screw rod 3, second
The thread rotary orientation of screw rod 4 is on the contrary, make the first screw rod 3, the second screw rod 4 stretch into the inside of swivel nut 5 and and spiral shell by the both ends of swivel nut 5 respectively
The threaded connection of set 5, makes the first screw rod 3, second one end of screw rod 4 away from swivel nut 5 are connected respectively with two structures 2, to cause
It can be swung in rotary threaded sleeve 5 with the free end of pushing structure body 2 along the radial direction of bolt body 1, in upper cap nut,
Two structures 2 are taken in grooving by rotary threaded sleeve 5, then screwed in from the initiating terminal of grooving to its terminal extreme direction direction
Nut, and after nut fixation, rotary threaded sleeve 5, are opened with two structures 2 of promotion to the peripheral direction of bolt body 1 again,
Stopped with being formed in nut unscrewing end so that nut can not screw out, so that nut can not come off.
In addition, in the present embodiment, the first screw rod 3 or the second screw rod 4 are provided with limiting section, and work as swivel nut 5 and limiting section support
By when, the structure 2 is located inside grooving, to facilitate the spinning in and out of nut.
In the present embodiment, structure 2 is the bar shape arranged along grooving bearing of trend, and is made by spring steel, with
Make governor motion promote two structures 2 opened to the outer wall direction of bolt body 1 when, two structures 2 it is close to each other one
Spacing between the axial line of side side and bolt body 1 is incremented by successively from the connection end of structure 2 to its free end, so that
When coordinating with bolt body 1 of nut is obtained, when the location of nut is between the both ends of structure 2, knot can be utilized
The bullet of structure body 2, which becomes ability, makes structure 2 can be with nut close to unscrewing end after producing certain deformation under the thrust of governor motion
Side side screws out direction without normal direction against so that nut and rotated, and so as to play the purpose that anti-nut loosens, while utilizes spring
The non-deformability of steel, structure 2 is set to recover native mode after thrust disappearance.And in the present embodiment, two structures 2
Side side close to each other is equipped with chute, first screw rod 3, second one end of screw rod 4 away from swivel nut 5 respectively with two
Slide connection on structure 2, so that governor motion can be moved up and down along the axial direction of bolt body 1, with
The convenient precession amount according to nut, adjust the opening angle of structure 2.
In the present embodiment, the side side that two structures 2 are located remotely from each other is the arc coaxially arranged with bolt body 1
Face, the first spiro tooth part that multiple short transverses along bolt body 1 are equally spaced is equipped with the cambered surface of two structures 2,
The outer surface of bolt body 1 is provided with multiple the second spiro tooth parts being equally spaced along its short transverse, and when two structures 2
The outer surface of cambered surface and bolt body 1 when same anchor ring, each first spiro tooth part on described two structures 2 respectively with spiral shell
Each second spiro tooth part on bolt body 1 docks to form the thread risen around the axial line helical disk of bolt body 1 correspondingly,
In use, it can make the smooth precession of nut by way of making the first spiro tooth part be docked with the second spiro tooth part, pass through pushing structure
The mode that body 2 opens, deforms thread, so that nut can not screw out, loosens dynamic effect so as to further improve.And for convenience
Adjustment, the present embodiment are provided with limiting section on the first screw rod 3, and when swivel nut 5 and limiting section support are leaned on, the first screw rod 3, second
Equal first spiro tooth part on screw rod 4 docks with the second spiro tooth part.
In the present embodiment, the side wall of structure 2 and grooving is rotatablely connected, so that structure 2 can be in the footpath of bolt body 1
Swing back and forth on to direction, so that the one end of structure 2 away from its connection end can be gone out by the sideslip of grooving, turned with facilitating
Movable snail sleeve 5.The outer surface of the swivel nut 5 is provided with anti-slip veins.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
