[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0028] See Figure 1 as shown;

[0029] This embodiment discloses an adjustable elevating bail pin, which includes:

[0030] An upper pin body 1 and a lower pin body 2;

[0031] The upper pin body 1 and the lower pin body 2 are connected by a plunger structure, and the plunger structure is divided into an upper plunger 301 clamped with the upper pin body 1 and a lower plunger 302 clamped with the lower pin body 2;

[0032] A spring 303 is connected between the upper plunger 301 and the lower plunger 302.

[0033] Specifically, this embodiment discloses an adjustable elevating bail pin, which is divided into an upper pin body 1 and a lower pin body 2. The upper pin body 1 and the lower pin body 2 are connected as a whole after being clamped by the upper plunger 301 and the lower plunger 302. In order to ensure that the plunger can be accurately inserted into the pin hole of the corresponding pin body, a spring 303 is arranged between the upper plunger 301 and the lower plunger 302 of this embodiment. When inserting the plunger, the characteristic that the spring 303 can be deformed by force enables the plunger to have a certain adjustment range, so that the plunger can adapt to the insertion requirements of pin bodies at different angles, ensure that the insertion is in place, avoid slipping out of the elevating bail, and avoid personal injury and drilling accidents.

[0034] Preferably, the upper pin body 1 of this embodiment includes:

[0035] The first connecting body 101 of the upper pin body and the second connecting body 102 of the upper pin body;

[0036] A magnetic attraction retaining ring 103 is arranged between the first connecting body 101 of the upper pin body and the second connecting body 102 of the upper pin body;

[0037] An upper pin body pin hole 104 is axially opened in the first connecting body 101 of the upper pin body, and the upper plunger 301 can be clamped in the upper pin body pin hole 104;

[0038] The second connecting body 102 of the upper pin body is connected with a lifting ring 4.

[0039] First of all, this embodiment further defines the structure of the upper pin body 1, which is divided into three parts, namely the first connecting body 101 of the upper pin body, the second connecting body 102 of the upper pin body and the magnetic attraction retaining ring 103 connecting the two; among them, the lifting ring 4 is connected with the second connecting body 102 of the upper pin body, and the first connecting body 101 of the upper pin body is provided with a pin hole for clamping and cooperating with the upper plunger 301.

[0040] Similar to the structure of the upper pin body 1, a lower pin body pin hole 201 is opened in the lower pin body 2 of this embodiment; the lower plunger 302 can be clamped in the lower pin body pin hole 201.

[0041] More specifically, the upper plunger 301 and the lower plunger 302 of this embodiment adjust the relative angle through the spring 303 between them to adapt to the corresponding pin holes.

[0042] During use, after the lifting ring 4 is installed on the upper pin body 1, the upper plunger 301 is inserted into the pin hole 104 of the upper pin body. When approaching the pin hole 201 of the lower pin body 2, the relative angle and direction between the lower plunger 302 and the lower pin body 2 are adjusted through the spring 303. Finally, the lower plunger 302 is inserted into the pin hole 201 of the lower pin body, effectively preventing the lifting ring 4 from disengaging from the elevating bail.

[0043] In the above technical solution, a kind of adjustable elevating bail pin provided by the utility model has the following beneficial effects:

[0044] The upper plunger 301 and the lower plunger 302 of the adjustable elevating bail pin of the utility model are connected by a spring 303. Arranging the spring 303 between the upper pin body 1 and the lower pin body 2 can increase the adjustable angle of the pin body, making it easy for the pin to be inserted into the pin hole of the elevating bail, thus solving the problem that the lifting ring cannot be inserted in place with the pin, preventing it from slipping out of the elevating bail, increasing the speed of running casing, and avoiding personal injury and drilling accidents.

[0045] Only some exemplary embodiments of the utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the utility model.
