Abstract
The utility model discloses a locking screw which comprises a screw rod and a nut. The screw rod and the nut are connected into a whole. The locking screw is characterized in that a ring-shaped groove is arranged at the connecting position of the screw rod and the nut. External threads are arranged on the screw rod, and regulating holes and internal thread locking holes are distributed on the nut. Moreover, the regulating holes and the internal thread locking holes are arranged on the same circumference on the periphery of the nut which located on the outer side of the screw rod. The locking screw is reasonable in structural design, good in locking positioning effect, and convenient to align and regulate, avoids the problems that accuracy of feeding is affected, the locking screw needs frequently replacing, working efficiency is affected, and the like due to the fact that the locking screw is easy to loosen, and screw teeth are prone to damage or fall off after being used for a long time, and meets usage requirement.
Description
Technical field
The utility model relates to a kind of screw, relates in particular to a kind of lock screw.
Background technique
Screw is the threaded fastener with various structure shape heads, is used for the fixing of various connections, and most of screws all are comprised of nut and screw rod, it is simple in structure, be applied between handwheel, screw mandrel and the scale plate of lathe feeding fixedly the time because the frequency of work, existing lock screw is when regulating, be inconvenient to regulate aligning, and locking and positioning is poor, and rear easily loosening, the thread of long-time use damages or comes off, and affects the accuracy rate of feeding, need often to change, affect working efficiency.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of lock screw is provided, it is simple to have solved existing bolt structure, regulate and aim at inconvenience, locking and positioning is poor, and rear easily loosening, the thread of long-time use damages or comes off, and affects the accuracy rate of feeding, need often to change, affect the problems such as working efficiency.
The utility model is achieved through the following technical solutions:
A kind of lock screw, include the screw rod and the nut that connect as one, it is characterized in that: described screw rod and nut joint are provided with annular groove, described screw rod is provided with outside thread, be distributed with adjustment hole and internal thread locking hole on the described nut, and adjustment hole and internal thread locking hole are positioned on the same circumference of nut edge in the screw rod outside.
Described nut is circular disk body.
Be evenly equipped with four adjustment holes on the described nut, on the described nut with the same circumference of adjustment hole and differ from the adjustment hole position and be provided with an internal thread locking hole.
Its principle is: by the structural design of screw rod self, adjust the gap between screw mandrel, dial and the handwheel, design by the adjustment hole on the nut and locking hole, regulate on time at needs, inserting the spanner that cooperates with the hole in the adjustment hole can realize regulating, easy to adjust, time saving and energy saving, screw in lathe handwheel Cock screw by locking hole simultaneously, increased the positioning and locking surface of contact, the handwheel end face is carried out dieback, avoided long-time use afterwards easily loosening, thread damage or come off, affect the accuracy rate of feeding, need often to change, affect the problems such as working efficiency
The utility model has the advantages that:
The utility model reasonable in design, locking and positioning is effective, aim at easy to adjust, avoided long-time use afterwards easily loosening, thread damage or come off, affect the accuracy rate of feeding, need often replacing, affect the problems such as working efficiency, satisfied usage requirement.
