Abstract
The invention discloses a bolt with an anti-disengagement device. The bolt comprises a bolt body. The bolt body comprises a bolt head and a bolt rod arranged at one end of the bolt head. The bolt rod comprises a first rod body and a second rod body. The anti-disengagement device is arranged outside the first rod body. Threads are arranged on the outer side of the second rod body. One end of the first rod body is connected with the bolt head. The other end of the first rod body is connected with the second bolt body. The anti-disengagement device comprises a spring gasket and a spacer, wherein the spring gasket is close to the bolt head and connected to the outer side of the first bolt body in a sleeved mode, and the spacer is away from the bolt head and connected to the outer side of the first bolt body in a sleeved mode. The bolt is novel in overall design and simple in design and structure, and has the specific advantages of being simple in structure, reasonable in design, convenient to operate, free of spring gasket finding, good in anti-disengagement effect, high in efficiency, good in locking effect and capable of saving time.
Description
Technical field
The present invention relates to bolt technical field, specially refer to a kind of bolt with locking device.
Background technique
Bolt coordinates with the tapped hole on nut or machine the effect that is connected fastening component of playing conventionally, when using bolt to lock component, after generally will first putting spring washer, lock again component, the elastic force of dependence spring washer increases the frictional force of the screw thread on bolt, and then prevent the loosening of bolt, although this method can well play the effect of screw retention, but before screwing on bolt, need to first find suitable spring washer, then be enclosed within on bolt, and then this program is comparatively complicated, to operator, brought inconvenience, also improved the operating time simultaneously, reduced efficiency.
Yet for the deficiencies in the prior art, developer be necessary to develop a kind of simple in structure, reasonable in design, easy to operate, without looking for spring washer, efficiency is high, locking effect good, the time saving bolt with locking device.
Summary of the invention
The problem existing for solving prior art, the object of the invention provide a kind of simple in structure, reasonable in design, easy to operate, without looking for spring washer, efficiency is high, locking effect good, the time saving bolt with locking device.
For solving above technical problem, the present invention realizes by the following technical solutions: a kind of bolt with locking device, comprise bolt body, and described bolt body comprises bolt head and is arranged on the bolt shank of bolt head one end;
Described bolt shank comprises first body of rod and second body of rod, and described the first body of rod outside is provided with loosening device, and described the second body of rod outside is provided with screw thread, and described first body of rod one end is connected with bolt head, and the other end is connected with second body of rod;
Described loosening device comprises near bolt head and is socketed in the spring washer in the first body of rod outside and away from bolt head and be socketed in the pad in the first body of rod outside.
In a preferred embodiment of the invention, described bolt head and bolt shank are formed in one.
In a preferred embodiment of the invention, described bolt head diameter is greater than bolt shank diameter.
In a preferred embodiment of the invention, described the first body of rod outer surface is smooth surface.
In a preferred embodiment of the invention, described the first body of rod diameter is less than the second body of rod diameter.
In a preferred embodiment of the invention, described loosening device can be free to slide in the second body of rod outside.
Beneficial effect of the present invention is, compared with prior art, bolt shank of the present invention comprises first body of rod and second body of rod, in the first body of rod outside, be provided with loosening device, in the second body of rod outside, be provided with screw thread, and loosening device comprises near bolt head, and be socketed in the spring washer in the first body of rod outside and away from bolt head, and be socketed in the pad in the first body of rod outside, and then when tighting a bolt, by pad holddown spring packing ring, and then avoided when tighting a bolt, need to first find suitable spring washer, then be enclosed within the complex steps on bolt, thereby improved the convenient function of operation, improved efficiency, reduced the operating time.
