Description

Technical Field

[0001] The utility model relates to the technical field of bolt fastening auxiliary tools, in particular to a bolt conversion joint. Background Art

[0002] In recent years, the domestic wind power industry has developed rapidly, the number of wind turbine installations has gradually increased, the size of wind turbines has gradually increased, and the size of bolts has gradually increased. Since wind turbines are mainly installed in windy areas, wind has a great impact on wind turbine hoisting, which leads to the need to wait for a window period for wind turbine hoisting. In these places, the window period will not be very long, so some new practical tools are needed to increase the speed of wind turbine hoisting. The tightening speed of bolts affects the efficiency of wind turbine hoisting to a certain extent. It takes too long to tighten the bolts by traditional pipe pliers. A new tool is needed to improve the efficiency of bolt tightening. Therefore, we propose a bolt conversion joint. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art. The tightening speed of bolts affects the efficiency of fan hoisting to a certain extent. The time required for tightening bolts by traditional pipe clamps is too long. A new tool is needed to improve the efficiency of bolt tightening.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A bolt conversion joint comprises a joint seat, one end of the joint seat is provided with an internal thread port assembly, and the other end is provided with an external hexagonal port, the internal thread port assembly is connected and fastened with a bolt, and the external hexagonal port is connected with a ratchet wrench or an electric wrench;

[0006] The internal thread port assembly comprises a plug-in connector, and an internal thread port is provided at one end of the plug-in connector away from the inside of the connector seat;

[0007] The joint seat and the internal thread port assembly are fixed via a connecting assembly.

[0008] As a preferred solution of the utility model, a docking groove is provided in the connector seat corresponding to the plug-in component, and is adapted to accommodate the plug-in component.

[0009] A further technical effect of the above scheme is: by preferably opening a docking groove at a position corresponding to the plug-in component in the connector seat, the docking groove is adapted to the plug-in component to ensure that the plug-in component can be securely accommodated in the docking groove, thereby achieving preliminary positioning between the connector seat and the plug-in component.

[0010] As a preferred solution of the utility model, the external hexagonal port and the connector seat are integrally formed.

[0011] A further technical effect of adopting the above scheme is that the integrity and stability of the structure are enhanced by adopting an integral molding design of the external hexagonal port and the connector seat, which not only simplifies the production process but also improves the durability and reliability of the connector.

[0012] As a preferred solution of the utility model, the connector is a cylindrical structure, and a docking protrusion is provided on the periphery of the connector along the length direction.

[0013] A further technical effect of the above solution is that a docking protrusion is provided on the periphery of the connector along the length direction, and the protrusion is used to adapt and mate with the docking groove in the connector seat, thereby achieving a stable connection between the connector and the connector seat.

[0014] As a preferred solution of the utility model, a docking groove matched with the docking protrusion is provided in the docking groove, and the assembly is completed by the docking protrusion and the docking groove being matched and matched.

[0015] A further technical effect of the above solution is that when the plug-in connector is inserted into the docking groove, the docking protrusion and the docking groove are adapted to mate with each other, thereby ensuring accurate alignment and stable connection between the plug-in connector and the connector seat.

[0016] As a preferred solution of the utility model, the connecting assembly includes a groove body opened on the periphery of the connector seat, the groove body is connected to the docking groove, and a groove hole corresponding to the groove body is provided on the docking protrusion. The connector seat and the connector are fixed by bolts that are connected to the groove body and the groove hole in sequence.

[0017] A further technical effect of the above scheme is that the slot body is connected with the docking groove, the slot hole corresponds to the slot body, and the slot body and the slot hole are connected in sequence by bolts to achieve a fixed connection between the docking seat and the connector. This connection method is simple, reliable, easy to operate and maintain.

[0018] As a preferred solution of the utility model, a bolt head hidden groove is reserved in the groove body, so as to embed the bolt.

[0019] A further technical effect of adopting the above scheme is: a bolt head hidden groove is left in the groove body to hide the bolt head, making the overall appearance more neat and beautiful. At the same time, the bolt head hidden groove can also prevent the bolt head from accidentally loosening or falling off during use.

[0020] As a preferred solution of the utility model, the connection between the internal thread port and the connector is chamfered at 45°.

[0021] A further technical effect of adopting the above scheme is: a 45° chamfer is performed at the joint between the internal thread port and the connector to reduce friction resistance during connection and improve the smoothness of the connection, and it can also effectively prevent stress concentration and damage to the thread during the connection process.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] Compared with the use of pipe clamps, the conversion joint of the utility model is more labor-saving and quick, ensures the efficiency of bolt tightening, and avoids the problem of easy slippage when workers use traditional pipe clamps to tighten bolts. It has a simple structure and is easy to use. The internal connector can be replaced when the internal threaded port and the reciprocating connection of the screw are worn and damaged, so that material loss is reduced.
