DETAILED DESCRIPTION
[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.
[0025] like Figure 1-6 As shown, according to one aspect of the utility model, a battery protection upper box assembly is provided, including a bottom battery box 1 and a fixed battery cover 2, the bottom battery box 1 is provided with a bottom side skirt 3 at the edge, and the fixed battery cover 2 is provided with a cover side skirt 4 at the edge, and the bottom side skirt 3 and the cover side skirt 4 are provided with a plurality of holes corresponding to each other on the surface, and the fixed battery cover 2 includes a box compartment 9 (such as Figure 2 , 3 As shown), after the fixed battery cover 2 is stuck on the top of the bottom battery box 1, the holes on the cover side skirt 3 of the fixed battery cover 2 are aligned with the holes on the bottom side skirt 3 of the bottom battery box 1, so that bolt structures can be used to pass through these holes for fixing.
[0026] In this embodiment, two inner fixing blocks 8 are fixedly installed on the inner and outer inner walls of the bottom battery box 1, and two side slide grooves 5 are provided on the inner and outer surfaces of the bottom battery box 1 and in the inner area of the inner fixing blocks 8, and an intermediate slide groove 6 (such as Figure 1 , 2 As shown), the side slide groove 5 is used to ensure that the lifting frame 7 can rise and fall, while the middle slide groove 6 ensures that the adjusting bolt 12 passes through and rises or falls with the lifting frame 7.
[0027] In this embodiment, the lifting frame 7 is sleeved inside the side slide groove 5, and the lifting frame 7 is penetrated by an adjusting bolt 12. The threaded end of the adjusting bolt 12 passes through the middle slide groove 6 and penetrates to the inner side of the inner fixing block 8. The bottom end of the inner fixing block 8 is provided with a pressing spring 10, and the upper part of the pressing spring 10 is in pressure contact with the lifting frame 7 (such as Figure 2As shown), the extrusion spring 10 is used to continuously squeeze the lifting frame 7, so that when the lifting frame 7 is in a relaxed state, the lifting frame 7 can be fixed above the inner fixing block 5 and will not easily shake up and down.
[0028] In this embodiment, the left and right ends of the adjusting bolt 12 are respectively provided with a limit ring 16 and a threaded sleeve 15, wherein the threaded sleeve 15 is threadedly connected to the threaded end of the adjusting bolt 12 (such as Figure 5 As shown), when the adjusting bolt 12 is rotated, the threaded sleeve 15 will be driven to move left and right.
[0029] In this embodiment, a pair of inclined blocks 13 are fixedly installed on the inner wall of the bottom battery box 1 and on the inner side of the inner fixed block 8, and an extrusion column 17 is fixedly installed on both sides of the threaded sleeve 15, and the extrusion column 17 is pressed and contacted with the inclined surface of the inclined block 13 (such as Figure 6 As shown), the other end of the squeezing column 7 is stuck in the pin groove on the inner wall of the lifting frame 7, so that the squeezing column 7 can only move left and right along the pin groove.
[0030] In this embodiment, a lifting card 14 is fixedly installed on the inner surface of the lifting frame 7, and four connecting cards 11 corresponding to the position of the inner fixed block 8 are fixedly installed inside the fixed battery cover 2. The connecting cards 11 are inserted into the interior of the inner fixed block 8 and are clamped under the lifting card 14.
[0031] The working principle of the device is: after the fixed battery cover 2 is clamped on the top of the bottom battery box 1, the holes on the cover side skirt 3 of the fixed battery cover 2 are aligned with the holes on the bottom side skirt 3 of the bottom battery box 1 (such as Figure 2 , 3 As shown), the bottom battery box 1 and the fixed battery cover 2 can be fixed through the hole.
[0032] After the fixed battery cover 2 is covered on the top of the bottom battery box 1 , its connection card 11 will also be inserted into the inner fixing block 8 , and the barb at the bottom end of the connection card 11 will be stuck under the lifting card 14 .
[0033] After that, it is only necessary to use the tool sleeve to rotate the adjusting bolt 12, so that the rotation of the threaded end of the adjusting bolt 12 will drive the threaded sleeve 15 to move to the left (such as Figure 5 As shown in FIG. 1 , the threaded sleeve 15 drives the extrusion column 17 to move to the left and squeeze the inclined surface end of the inclined surface block 13. Due to the interaction between the inclined surface block 13 and the extrusion column 17, the extrusion column 17 drives the adjustment bolt 12 to move downward and drives the lifting frame 7 to move downward. The lifting clamp 14 is installed on the lifting frame 7. At this time, after the lifting clamp 14 moves downward, it will squeeze the connecting clamp 11 downward, thereby firmly fixing the fixed battery cover 2 above the bottom battery box 1.
[0034] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
