Tooth thread lock ring, to solve the problem of prior art is present.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of to be applied to packer, the sawtooth spiral shell of bridging plug
Line lock ring, it includes buttless thread lock ring, body and lock ring set, and buttless thread lock ring is sleeved between body and lock ring set, saw
The inner surface of tooth thread lock ring and outer surface are respectively equipped with closely-pitched buttless thread and coarse thread buttless thread, closely-pitched buttless thread and sheet
External screw thread connection on body, coarse thread buttless thread is connected with the internal thread that lock ring is put.
The described C-shaped open ring structure of tooth thread lock ring.
The tooth height of described closely-pitched buttless thread is high higher than the external screw thread tooth of body, and the internal thread pitch of lock ring set is more than thick
The pitch of tooth buttless thread.
The load-carrying surface of the coarse thread buttless thread of described buttless thread lock ring has 3 ° ~ 5 ° of folder with the buttless thread lock ring flank of tooth
Angle, confined planes and the buttless thread lock ring flank of tooth of coarse thread buttless thread have 115 ° ~ 125 ° of angle.
Described closely-pitched buttless thread and coarse thread buttless thread can be segmentation structure.
The internal thread flute profile of external screw thread flute profile and the lock ring set of described body is stepped tooth.
On the end face of described tooth thread lock ring, the center away from openend is provided with deep gouge.
The utility model has advantages below：
1st, buttless thread lock ring and lock ring set move unobstructed along tooth, and resistance is small.
2nd, buttless thread lock ring and lock ring set inverted teeth axial carrying capacity are strong.
3rd, the opening expansion and recovery reaction of buttless thread lock ring are fast.
Brief description of the drawings
Fig. 1 is structural profile schematic diagram of the present utility model；
Fig. 2 is Fig. 1 I portions close-up schematic view；
In figure：1- buttless thread lock rings, 2- closely-pitched buttless threads, 3- coarse thread buttless threads, 4- bodies, 5- lock ring sets.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but protection domain of the present utility model is not limited to
It is as described below.
As depicted in figs. 1 and 2, a kind of to be applied to packer, the buttless thread lock ring of bridging plug, it includes buttless thread lock ring
1st, body 4 and lock ring set 5, buttless thread lock ring 1 are sleeved between body 4 and lock ring set 5, the inner surface of buttless thread lock ring 1
Closely-pitched buttless thread 2 and coarse thread buttless thread 3 are respectively equipped with outer surface, closely-pitched buttless thread 2 connects with the external screw thread on body 4
Connect, coarse thread buttless thread 3 covers the internal thread on 5 with lock ring and is connected.
The described C-shaped open ring structure of tooth thread lock ring 1.
The tooth height of described closely-pitched buttless thread 2 is high higher than the external screw thread tooth of body 4, and the internal thread pitch of lock ring set 5 is big
In the pitch of coarse thread buttless thread 3.
The load-carrying surface of the coarse thread buttless thread 3 of described buttless thread lock ring 1 has 3 ° ~ 5 ° with the end face of buttless thread lock ring 1
Angle, the confined planes of coarse thread buttless thread 3 have 115 ° ~ 125 ° of angle with the end face of buttless thread lock ring 1.
Described closely-pitched buttless thread 2 and coarse thread buttless thread 3 can be segmentation structure.
The internal thread flute profile of external screw thread flute profile and the lock ring set 5 of described body 4 is stepped tooth.
On the end face of described tooth thread lock ring 1, the center away from openend is provided with deep gouge.
The course of work of the present utility model is as follows：The C-shaped open ring structure of buttless thread lock ring 1, buttless thread ring lock 1 is filled
Fit between body 4 and lock ring set 5, the closely-pitched buttless thread 2 of buttless thread lock ring 1 is connected with the external screw thread of body 4, sawtooth spiral shell
