Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
With reference to Fig. 1-3, a kind of scalable secured adjusted device of steel pipe, including shank of the key 1, first mounting disc 2, cam 6 and the second mounting disc 5, shank of the key 1 and the first mounting disc 2 are arranged on one end of shank of the key 1, first mounting disc 2 is connected away from one end and the cam 6 of shank of the key 1 is fixing, cam 6 is connected away from one end and second mounting disc of the first mounting disc 2 is fixing, and first mounting disc 2, second mounting disc 5 is all coaxially disposed with shank of the key 1, shank of the key 1 and the first mounting disc 2, first mounting disc 2 and cam 6, cam 6 and the second mounting disc 5 are all structure as a whole, make this adjustment device more stable, during practice, shank of the key 1 is connected with the first steel pipe 9, shank of the key 1 is plugged in the second steel pipe 10 together with the first steel pipe 9 and forms expansion link.
The lock ring 3 of a circular arc it is provided with between the first mounting disc 2 and the second mounting disc 5, lock ring 3 is fastened on cam 6, lock ring 3 is equipped with multiple tread plate 7 away from the one side two ends of cam 6, multiple tread plates 7 arrange along cam 6 length surface direction, every tread plate 7 all be arranged in parallel with lock ring 3 axis, when the first steel pipe 9 rotates, tread plate 7 is vertical with the rotation direction of the first steel pipe 9 all the time, there is skid resistance more, wherein the first mounting disc 2 is equal with the second mounting disc 5 frontal projected area, and tread plate 7 is exposed to the surface of the first mounting disc 2 and the second mounting disc 5；Second mounting disc 5 is fixed with the locking plate 4 of a circular arc, and locking plate 4 be arranged in parallel with lock ring 3, when the first steel pipe 9 rotates, the contact internal walls of locking plate 4 and the second steel pipe 10, prevent frictional force between the second mounting disc 5 and the second steel pipe 10 excessive, it is difficult to rotate, be equipped with slipmat 8 at the inner surface two ends of lock ring 3, the junction of the two ends of slipmat 8 and lock ring 3 all adopts arc transition, and set slipmat 8 can increase stablizing between cam 6 and lock ring 3.
