For example, it may be a fixed connection, a detachable connection or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1-4, the bolt set 20 includes a bolt and a nut, the bolt and the nut are installed in a matching manner to fix the motor for locking and unlocking the hanger on the motor base 10, and the hanger vibrates continuously during operation, so that the nut and the bolt in the bolt set 20 are loosened and screwed down manually, thereby preventing accidents.

As shown in fig. 3 and 4, the motor base 10 is generally designed to be a closed box type due to the limitation of the working environment and state, and the motor is installed in the motor base 10, and when the fastening bolt group 20 between the motor base 10 and the motor is loosened, the bolt is also rotated during the process of screwing the nut, so that the operation is difficult.

As shown in fig. 1 and 2, the bolt fixing tool of the present embodiment includes a limiting portion 30 for limiting rotation of the bolt set 20, a connecting rod assembly connected to the limiting portion 30, and a locking portion 60 located at the other end of the connecting rod assembly, where the locking portion 60 is used to lock the whole fixing tool on the motor base 10, so as to reduce additional auxiliary fixing and personnel allocation.

A limiting groove 31 is formed on the limiting part 30, and the limiting groove 31 extends downwards from the upper surface of the limiting part 30; in a working state, the bottom bolt of the bolt group 20 is positioned in the limiting groove 31, the bottom bolt is fixed to prevent the bottom bolt from rotating, and then the nut positioned on the outer side of the motor base 10 is screwed down or detached by an operator.

Specifically, the limiting groove 31 has a polygonal structure, preferably, a hexagonal shape matched with the shape of the nut, so as to facilitate better positioning.

The connecting rod assembly is detachably connected to the bottom of the limiting portion 30, the tail end of the connecting rod assembly is connected with a locking portion 60, and the locking portion 60 is used for fixing the connecting rod assembly and the limiting portion 30 on the motor base 10.

The connecting rod assembly comprises a supporting rod 40 and an adjusting rod 50, an observation port is formed in the general side wall of the existing motor base 10, the installation port 11 is used as a limiting part 30 and an installation port 11 for installing the connecting rod assembly, the bolt group 20 is positioned at the upper top of the motor base 10, the bolt fixing tool needs to go deep into the motor base 10 from the installation port 11 and fix a bolt positioned in the motor base 10, and therefore, in order to adapt to the structural relationship between the motor base 10 and the bolt group 20, the supporting rod 40 is perpendicular to the adjusting rod 50.

In order to adapt to the bolt sets 20 with different sizes, the limiting part 30 is detachably connected with the connecting rod assembly, the limiting groove 31 with different sizes or shapes can be designed on the limiting part 30 in a targeted mode, specifically, a jack is formed at the bottom end of the limiting part 30, the supporting rod 40 is inserted into the jack, and the limiting part 30 and the supporting rod 40 can be conveniently detached and replaced.

In some embodiments of the application, in order to facilitate the deepening and the positioning of the tool, the end of the adjusting rod 50 is provided with a through-long external thread structure, a threaded hole is formed in the locking portion 60, the adjusting rod 50 is connected to the locking portion 60 through threads, when the connecting rod assembly and the limiting portion 30 are deeply inserted into the motor base 10 and the positioning is completed, the locking portion 60 is installed at the tail end of the adjusting rod 50 of the connecting rod assembly, the locking portion 60 is rotated to be in contact with the side wall of the motor base 10 according to the position of the actual motor base 10, the connecting rod assembly and the limiting portion 30 are fixed, an operator does not need to hold the tool by hand and fix the tool, and manpower is saved.

The locking portion 60 is formed with a contact surface 61, and the contact surface 61 is used for increasing the locking area, so that the locking fixation is firmer and more stable.

The working process is as follows:

according to the size of the bolt group 20 which needs to be fastened or dismounted actually, the limiting part 30 provided with the limiting groove 31 corresponding to the size and the shape is selected, the limiting part 30 is inserted into the supporting rod 40, the end part of the adjusting rod 50 is held by hand, the supporting rod 40 and the limiting part 30 are inserted into the motor base 10 from the mounting hole 11, the limiting groove 31 of the limiting part 30 corresponds to the bolt inside the motor base 10, the bolt is fixed and limited, and the bolt is prevented from rotating in the later period when the nut is dismounted.

After spacing portion 30 installed in place, at the terminal installation locking portion 60 of adjusting pole 50, fix whole frock to motor base 10 through locking portion 60, after the bolt fastening in motor base 10, can easily fasten bolt group 20 or dismantle by an operating personnel, use this work, except playing spacing fixed work, in dismantling bolt group 20, after nut and bolt separation, the bolt can directly fall into spacing recess 31, prevent to scatter and lose.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
