[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] The present application provides a bolt fastening device for installing a battery rack. Figure 1 A schematic diagram of the overall structure of a bolt fastening device for installing a battery rack is shown; Figure 2 A schematic diagram of the planar structure of a bolt fastening device for installing a battery rack is shown; Figure 3 Shows Figure 2 Schematic diagram of the cross-section structure at AA in the middle;

[0024] Figure 1-Figure 3 In the present invention, the bolt fastening device for installing a battery rack includes a side "U"-shaped frame 100; and further includes:

[0025] A step hole 110 is formed on the bottom surface of the side "U"-shaped frame 100 and penetrates through it. A first magnet 113 is installed in the step hole 110 to attract the nut;

[0026] A pressure rod 120 passes through the top surface of the side "U"-shaped frame 100 and is coaxially arranged with the step hole 110;

[0027] The sleeve 130 is coaxially mounted on one end of the pressure rod 120 facing the step hole 110. The end of the sleeve 130 facing the step hole 110 has an opening 131. A second magnet 132 is installed in the opening 131 to attract the bolt.

[0028] The sleeve 130 is driven by an external force and can move along the trajectory of the pressure rod 120 toward the stepped hole 110 to complete the docking of the bolt and the nut.

[0029] During installation, the nut is placed in the step hole 110, and the first magnet 113 in the step hole 110 can absorb the nut to prevent it from falling off. The bolt is placed in the opening 131 and can be absorbed by the second magnet 132. The side "U"-shaped frame 100 is moved as a whole to align the step hole 110 with the installation opening, and then the sleeve 130 is driven to move toward the step hole 110, so that the bolt and the nut can be docked. In the present application, the nut and the bolt are adsorbed by the first magnet 113 and the second magnet 132, so that the problem of the nut or the bolt falling off can be avoided. At the same time, the movable sleeve 130 can drive the bolt to move toward the nut along a specified trajectory to complete the docking, thereby solving the problem of the difficulty of aligning the traditional bolt and nut.

[0030] It should be noted that the shape of the opening 131 matches the shape of the bolt. In the present application, the shape of the opening 131 is hexagonal, but in some other embodiments, it can be changed according to the shape of the bolt head.

[0031] See also Figure 3 The step hole 110 has a first step groove 111, the shape of the first step groove 111 matches the nut, and the first magnet 113 is installed on the step surface of the first step groove 111;

[0032] After the nut is placed in the first step groove 111 , the upper surface of the nut is flush with the upper edge of the first step groove 111 .

[0033] In the present application, the shape of the first step groove 111 is set to be a regular hexagon, but this is not a limitation on its shape. In some other embodiments, the shape of the first step groove 111 can be a regular pentagon or other irregular shapes. What the present invention emphasizes is that the first step groove 111 matches the nut and can limit the nut from being offset.

[0034] Continue to see Figure 3The step hole 110 also has a second step groove 112 for placing a gasket. The second step groove 112 is arranged above the first step groove 111 and borders it. After the gasket is placed in the second step groove 112, the upper surface of the gasket, the upper edge of the second step groove 112 and the upper surface of the bottom table of the side "U"-shaped frame 100 are in the same horizontal plane.

[0035] It should be noted that in the present application, the shape of the second step groove 112 is circular, but this is not a limitation thereof. In some other embodiments, the second step groove 112 can also be set to other regular or irregular shapes to meet the restrictions on the gasket.

[0036] Continue to see Figure 3 The top of the side "U"-shaped frame 100 has a support sleeve 140, and the pressure rod 120 passes through the support sleeve 140, and the cross section of the pressure rod 120 is a circle.

[0037] Since the pressure rod 120 is a cylinder, the pressure rod 120 can slide up and down in the support sleeve 140 to drive the bolt to move, and can also rotate after the bolt and the nut are connected to complete the installation process of the two.

[0038] Continue to see Figure 1 and Figure 3 A swing rod 150 radially penetrates the pressure rod 120, and two ends of the swing rod 150 have radially extending limiting portions.

[0039] In order to reduce the resistance of rotating the pressure rod 120, a swing rod 150 is radially penetrated in the pressure rod 120, so as to increase the length of the power arm.

[0040] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
