Abstract
The utility model relates to a same length screw bolt with dual heads and a disassembling head, which belongs to a locking device of a special shape of a screw bolt. When same length screw bolt with dual heads and a disassembling head is adopted, one head of a fine thread is lengthened, the lengthening part is a disassembling head (1), and the disassembling head can be a square shape or a hexagonal shape. The utility model is particularly used for a screw of a back axle of an automobile, and the length of the disassembling head (1) is not less than 8 mm; so the utility model has the advantages of convenient assembly and convenient maintenance.
Description
A kind of isometric stud bolt that the loading and unloading head is arranged.Belong to locking device with the special shape of bolt.
Axle shaft screw adopts the isometric stud bolt of M12 behind Dongfeng brand, the Jiefang brand truck at present.One on this bolt is a coarse thread, and the other end is a fine thread.When changing this bolt, must unload the back semiaxis earlier, piece together tightly again with serrated nut, just can unload bolt.As stripped thread, it is more difficult to load and unload.Under the normal condition, load and unload 14 axle shaft screws, at least also want 20 minutes, take a lot of work, time-consuming.With special-purpose double-threaded screw adjustable spanner, help loading and unloading, but injure screw thread easily.
The purpose of this utility model provides and a kind ofly is exclusively used in semiaxis behind Dongfeng brand, the Jiefang brand truck, and has the stud bolt of loading and unloading head.
Solution of the present utility model is that its elongated portion of one of stud bolt fine thread lengthening is the loading and unloading heads, and the loading and unloading head can be square or hexagon, directly turns the loading and unloading head with special-purpose cover or common wrench, can load and unload, and the saving of labor, saves time.
The utility model loads and unloads with handling instrument easily because stud bolt closely-pitched head has the loading and unloading head, therefore helps assembling and maintenance.
Accompanying drawing is the utility model example structure schematic representation.
(2) one of bolt fine threads loading and unloading heads (1) are arranged, the loading and unloading head can be square or hexagon.
Isometric stud bolt diameter is 12mm, the long 20mm of screw thread, and the loading and unloading head length is not less than 8mm, and preferentially adopts square.
Claims (3)
1, a kind of isometric stud bolt that the loading and unloading head is arranged, be exclusively used in the stud bolt of semiaxis behind Dongfeng brand, the Jiefang brand, there is isometric screw thread at two, one is coarse thread, the other end is fine thread (2), it is characterized in that with lengthening of fine thread its elongated portion is loading and unloading heads (1), the loading and unloading head is square.
