[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a slip hanger with an auxiliary sealing structure, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a locking seat structure 1, which includes a first locking seat 11. A second locking seat 12 is rotatably connected to the left side of the first locking seat 11 via a rotating assembly 13. Fixing assemblies 14 are fixed to the right sides of both the second locking seat 12 and the first locking seat 11. The rotating assembly 13 includes a rotating rod 131, and a rotating ring 132 is rotatably connected to the rotating rod 131. A connecting plate 133 is fixed between the rotating rings 132. The fixing assembly 14 includes a first fixing plate 141, and the first fixing plates 141 are connected and disassembled by screws 142.

[0022] Both the first locking seat 11 and the second locking seat 12 are arc-shaped.

[0023] Specifically, the first slip seat 11 and the second slip seat 12 are both provided with limiting grooves, and a rotating rod 131 is fixed in the limiting grooves. The connecting plate 133 is arranged in an arc shape.

[0024] Furthermore, a first fixing plate 141 is fixed on both the first clamping seat 11 and the second clamping seat 12. Two sets of threaded holes 34 are opened on both sets of first fixing plates 141. The two sets of threaded holes 34 are disassembled and installed by screws 142.

[0025] In the above scheme, with the assistance of the rotating ring 132 on the upper side of the rotating rod 131 on the first clamp seat 11 and the second clamp seat 12, the connecting plate 133 rotates, thereby driving the second clamp seat 12 to rotate to the required position. The first fixing plate 141 on the first clamp seat 11 fits against the first fixing plate 141 on the second clamp seat 12. Finally, the first fixing plate 141 is limited and fixed by the screw 142.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, the slip tooth assembly 3 is disassembled and installed on the upper side of the slip seat structure 1. The slip tooth assembly 3 includes a support seat 31, a slip tooth plate 32 is fixed on the support seat 31, and a slip tooth body 33 is fixed on the slip tooth plate 32. The support seat 31 has a threaded hole 34 and a waist hole 35, and the waist hole 35 is located below the threaded hole 34.

[0027] The support base 31 is arranged in a ring shape, and six sets of threaded holes 34 are evenly distributed on the support base 31. The six sets of threaded holes 34 are evenly distributed on the support base 31. Three sets of waist holes 35 are opened between the support base 31 and the jaw plate 32. The three sets of waist holes 35 are evenly distributed about the central axis of the support base 31. Anti-slip rubber protective pads are provided in the threaded holes 34 and waist holes 35 to protect the screw 142 and the support base 31.

[0028] Furthermore, the slip plate 32 is cone-shaped, and multiple slip bodies 33 are formed on the inner wall of the slip plate 32;

[0029] In the above scheme, the slip plate 32 on the support base 31 passes through the space enclosed by the first slip seat 11 and the second slip seat 12. The support base 31 is placed on the upper side of the first slip seat 11 and the second slip seat 12. The screw 142 passes through the threaded hole 34 and is rotated to fix it. The screw 142 passes through the waist hole 35. Rotating the screw 142 provides auxiliary limiting and fixing for the support base 31 and the slip plate 32, ensuring that the slip tooth body 33 on the slip plate 32 can be used normally.

[0030] like Figure 1 As shown, the first rubber sealing ring 2 is engaged between the slip tooth assembly 3 and the slip seat structure 1. A sealing assembly 4 is fixed on the lower side of the slip seat structure 1. The sealing assembly 4 includes an annular seat 41. A second sealing rubber ring 42 and a support washer 43 are embedded in the annular seat 41. The support washer 43 is located between the second sealing rubber rings 42.

[0031] The annular seat 41 is composed of two sets of arc-shaped seats. The annular seat 41 is hollow. A second sealing rubber ring 42 is provided between the annular seat 41 and the first slip seat 11 and the second slip seat 12.

[0032] Furthermore, two sets of second sealing rubber rings 42 are provided, and the two sets of second sealing rubber rings 42 are symmetrically arranged about the central axis of the support washer 43;

[0033] In the above scheme, the first rubber sealing ring 2 is used to prevent the support seat 31 from directly contacting the upper side of the first slip seat 11 and the second slip seat 12, thereby protecting the support seat 31. The two sets of second sealing rubber rings 42 and support gaskets 43 on the annular seat 41 achieve a double sealing effect.

[0034] Working principle: When using the slip hanger with auxiliary sealing structure, the slip seat structure 1 supports the slip tooth assembly 3, the first rubber sealing ring 2 protects the slip seat structure 1 and the slip tooth assembly 3, and the sealing assembly 4 ensures the sealing effect of the slip hanger.
