[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 4The anti-loosening connection structure of the power output terminal of the electric bicycle includes a positioning frame 1. The positioning frame 1 is rectangular in design. A plurality of positioning holes 12 are opened on the positioning frame 1. The positioning frame 1 is fixedly installed on the outside of the power output terminal of the electric bicycle through the positioning holes 12. The through-opening size of the middle part of the positioning frame 1 is larger than the socket size of the power output terminal. The front wall of the positioning frame 1 is symmetrically provided with angle plates 1 and 2. The angle plates 1 and 2 are respectively located at the upper and lower ends of the positioning frame 1. The front end of the angle plate 1 is fixedly connected with a vertically upward support plate 1 3. The front end of the angle plate 2 is fixedly connected with a vertically downward support plate 2 4. Under the support of the angle plates 1 and 2, the support plates 1 3 and 2 4 are separated from the front wall of the positioning frame 1.

[0020] Adjustment mechanisms are provided between support plate 1 3 and angle plate 3 5 and between support plate 2 4 and angle plate 4 6. The adjustment mechanisms include notches 9 provided on support plate 1 3 and support plate 2 4. The notches 9 are vertically provided in strips and penetrate the upper wall of support plate 1 3 and the lower wall of support plate 2 4 respectively. Threaded holes corresponding to the notches 9 are provided on angle plate 3 5 and angle plate 4 6. Screws 10 are inserted in the threaded holes. The rear ends of the screws 10 are fixedly connected with baffles 11 located on the rear sides of support plate 1 3 and support plate 2 4 respectively. The front side walls of the baffles 11 are provided with anti-slip pads. After tightening the screws 10 on angle plate 3 5 and angle plate 4 6, the baffles 11 will squeeze the rear side walls of support plate 1 3 and support plate 2 4, so that angle plate 3 5 and angle plate 4 6 are fixed on support plate 1 3 and support plate 2 4 respectively. At the same time, after loosening the screws 10, the positions of angle plate 3 5 and angle plate 4 6 can be adjusted.

[0021] The opposite side walls of angle plate three 5 and angle plate four 6 are fixedly connected with elastic plate one 7 and elastic plate two 8 respectively, the middle parts of elastic plate one 7 and elastic plate two 8 both protrude toward the middle part of positioning frame 1, elastic plate one 7 and elastic plate two 8 both include a fixed end and a movable end, the fixed ends are fixedly connected with the lower side wall of angle plate three 5 and the upper side wall of angle plate four 6 respectively, the movable ends are respectively located at the front sides of support plate one 3 and support plate two 4, so that angle plate three 5 can drive elastic plate one 7 to move upward along support plate one 3, or angle plate four 6 can drive elastic plate two 8 to move downward along support plate two 4, so that elastic plate one 7 and elastic plate two 8 can be adjusted respectively with angle plate three 5 and angle plate four 6.

[0022] To prevent angle plate three 5 and angle plate four 6 from rotating during adjustment, the front walls of support plate one 3 and support plate two 4 are symmetrically provided with vertical slide grooves 13, and the lower side walls of angle plate three 5 and angle plate four 6 are symmetrically provided with slide rods 14, which are slidably inserted in the corresponding slide grooves 13. Under the guiding action of slide rods 14 and slide grooves 13, the deflection of angle plate three 5 and angle plate four 6 is avoided. The positioning frame 1 in the utility model is fixedly installed on the outside of the power output terminal. When the wire plug is inserted into the power output terminal, elastic plate one 7 and elastic plate two 8 generate extrusion force on the outer wall of the plug, which squeezes the plug onto the power output terminal, thereby improving the stability of the plug-in connection with the output terminal. At the same time, the spacing between elastic plate one 7 and elastic plate two 8 can be adjusted to adapt to plugs of different sizes, thereby improving the applicability of the anti-loosening connection structure.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
