There is the situation of bolt looseness, ensure the property loss that operation is made, avoids that precocity is unnecessary of equipment, with simple in construction,
Cost is cheap, it is easy to spread the advantages of.
Technical scheme is used by the utility model：A kind of Self-locking bolt, including the nut with axis hole, screw rod and
It is described with the integrally formed bolt head of screw rod, in addition to neck, pin-and-hole, connecting hole, through hole, elastic component, self-lock pin and connecting pin
Neck be arranged on screw rod, described pin-and-hole sets above-mentioned elastic component and self-lock pin in the nut in described pin-and-hole,
Described elastic component one end is connected with pin-and-hole inwall, and the other end and self-locking pin connection, described connecting hole are connected with pin-and-hole, institute
The connecting pin stated is placed in connecting hole and its one end is connected with self-lock pin, and projection, described through hole are provided with described connecting hole
One end is connected with connecting hole, and the other end communicates with nut outer surface.
Further, the neck is set along screw rod outer periphery, and its depth is the 25%-40% of screw diameter.
Further, described pin-and-hole is mutually perpendicular to connecting hole, and described through hole is mutually perpendicular to connecting hole.
Further, described self-lock pin is vertical with connecting pin.
Further, described self-lock pin is T fonts, including cylindrical end and is caught in end, and it is cuboid that described being caught in, which is held,
Its thickness is less than the width of neck.
Further, described connecting pin one end is provided with circular depressed.
Further, described projection top is circular arc or angular.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, the Self-locking bolt has well oneself
Lock ability, applied to the situation in the equipment rocked of vibrations or environment being not in bolt looseness, ensure equipment is made operation,
Avoid the property loss that precocity is unnecessary, have it is simple in construction, cost is cheap, it is easy to spread the advantages of.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 7, a kind of Self-locking bolt, including the nut 1 with axis hole, screw rod 2 and with the one of screw rod 2
The bolt head 3 of shaping, in addition to neck 4, pin-and-hole 5, connecting hole 6, through hole 7, elastic component 8, self-lock pin 9 and connecting pin 10, it is described
Neck 4 be arranged on screw rod 2, described pin-and-hole 5 sets the above-mentioned He of elastic component 8 in the nut 1 in described pin-and-hole 5
Self-lock pin 9, described one end of elastic component 8 are connected with the inwall of pin-and-hole 5, and the other end is connected with self-lock pin 9, described connecting hole 6 with
Pin-and-hole 5 is connected, and described connecting pin 10 is placed in connecting hole 6 and its one end is connected with self-lock pin 9, in described connecting hole 6
Provided with projection 11, described one end of through hole 7 is connected with connecting hole 6, and the other end communicates with the outer surface of nut 1.
Preferably, the neck 4 along the outer periphery of screw rod 2 set, its depth be the diameter of screw rod 2 25%-40%, neck
4 depth are not easy excessive, not so can influence the mechanical strength of screw rod 2；Described pin-and-hole 5 is mutually perpendicular to connecting hole 6, and described is logical
Hole 7 is mutually perpendicular to connecting hole 6, and described self-lock pin 9 is vertical with connecting pin 10, and described self-lock pin 9 is T fonts, including circle
Styletable 12 and it is caught in end 13, the described end 13 that is caught in be cuboid, and for its thickness less than the width of neck 4, this structure is easy to self-locking
Pin 9 is caught in neck 4.
Preferably, described one end of connecting pin 10 is provided with circular depressed 14, and when in use, circular depressed 14 is easy to bar
Shape bar contradicts, and prevents bar shaped bar sideslip, looks for inaccurate position, the described top of projection 11 is circular arc or angular, and projection 11, which plays, lifts up
The point action of seesaw, angular and circular energy provide more preferable rotation space.
When in use, pushed with the circular depressed on bar shaped bar alignment connecting pin 10, will be certainly using the principle of regulations and parameters
Lock pin 9 is retracted in pin-and-hole 5, then screwing bolts and nut, unclamps bar shaped bar after screwing, will be certainly using the elastic force of elastic component 8
