Description

Technical Field

[0001] This utility model relates to a fastening structure, specifically a ball nut locking structure for clamping low-voltage batteries on heavy trucks. Background Technology

[0002] Currently, the common method for securing low-voltage batteries on heavy-duty trucks is to use a long tie rod. One end is hooked to the bottom of the battery frame, and the other end passes through the upper pressure plate of the battery and is locked with a regular nut. Because the nut contacts the plane of the pressure plate when locking the battery with a regular nut, this structure restricts the direction of the long tie rod, meaning the tie rod can only be arranged perpendicular to the plane of the pressure plate, resulting in a limitation on the arrangement space. Utility Model Content

[0003] This utility model provides a ball nut locking structure for securing low-voltage batteries on heavy-duty trucks, which solves the problem of limited space caused by using ordinary nuts to lock batteries.

[0004] This utility model is achieved through the following technical solution:

[0005] A ball nut locking structure for securing a low-voltage battery on a heavy-duty truck includes a ball nut 1, a pressure plate 2 with a U-shaped groove, and a long pull rod 3. One end of the long pull rod 3 is threaded, and the other end is a hook-shaped structure. The hook-shaped head hooks onto the base plate on the battery frame, and the threaded end of the long pull rod 3 passes through the U-shaped opening in the middle of the pressure plate 2 with the U-shaped groove. The ball nut 1 has a threaded through hole in the middle, which is connected to the threaded head of the long pull rod 3. After connection, the spherical surface of the ball nut 1 fits tightly with the U-shaped groove of the pressure plate 2 with the U-shaped groove, and the flat surface of the pressure plate 2 with the U-shaped groove is tightly pressed against the edge of the battery.

[0006] This invention eliminates the spatial limitations of locking mechanism arrangement, improves the adaptability of a single mechanism to different products, and increases the versatility of this type of mechanism. Attached Figure Description

[0007] Figure 1 This is a diagram showing the composition of this utility model. Detailed Implementation

[0008] This utility model relates to a ball nut locking structure for securing low-voltage batteries on heavy-duty trucks. See the specific arrangement below. Figure 1 The long pull rod 3 has a threaded end and a hook-shaped structure at the other end. The hook-shaped head hooks onto the base plate on the battery frame. The threaded end of the rod passes through the U-shaped opening in the middle of the pressure plate 2 with a U-shaped groove. The ball nut 1 has a threaded through hole in the middle and is connected to the threaded head of the long pull rod 3. After connection, the spherical surface of the ball nut 1 fits tightly with the U-shaped groove of the pressure plate 2 with a U-shaped groove, and the flat surface of the pressure plate 2 with a U-shaped groove is pressed tightly against the edge of the battery.

[0009] This utility model's nut locking structure, through the combination and connection of a spherical nut 1, a pressure plate 2 with a U-shaped groove, and a long pull rod 3, forms a simple locking mechanism that can be quickly assembled and disassembled. Because the spherical surface of the spherical nut 1 is in spherical contact with the U-shaped groove on the pressure plate 2, when the spherical surface 1 of the spherical nut moves along the U-shaped groove on the pressure plate 2, the direction of the thread center of the spherical nut 1 can be arbitrarily changed within a certain range, allowing the spatial orientation of the long pull rod 3 connected to it to be arbitrarily changed and adjusted.
