DETAILED DESCRIPTION

[0016] The preferred embodiments of the utility model patent are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model patent and are not intended to limit the protection scope of the utility model patent.

[0017] The utility model patent proposes an automatically opened balancing machine protective cover, including a balancing machine box 24, a balancing machine shaft 23, a tire 22, a rear box 3, and a balancing machine protective cover 21. The rear box 3 is installed on the balancing machine box 24, and a box body vertical plate 9 is also installed on the rear box 3. A pair of fixed shaft sleeves 11 are installed on the rear box 3 and the box body vertical plate 9. A protective cover rotating shaft 12 is installed in the pair of fixed shaft sleeves 11. An energy storage torsion spring 4 is installed on the protective cover rotating shaft 12. A steering plate 5 and a steering rod 8 are installed on the protective cover rotating shaft 12 and located on one side of the box body vertical plate 9. The box body vertical plate 9 is also installed There is a limit axis 10 and an in-position switch 13, and an electronic lock 6 is also installed on the rear box body 3; the balancing machine protective cover 21 includes a protective cover 1 and a protective cover bracket 2, and the protective cover bracket 2 is installed on the protective cover rotating shaft 12; the steering plate 5 is provided with a lower limit stop 5-1, an upper limit stop 5-2 and an in-position switch stop 5-3; the electronic lock 6 is installed on the rear box body 3 through an electronic lock fixing screw 7; the in-position switch 13 is installed on the box body vertical plate 9 through an in-position switch fixing screw 14; the energy storage torsion spring 4 is sleeved on the protective cover rotating shaft 12 and is located between the rear box body 3 and the box body vertical plate 9.

[0018] First, manually lower the protective cover 1 to start the measurement. The protective cover 1 is installed on the protective cover bracket 2. Both ends of the protective cover shaft 12 welded on the protective cover bracket 2 are installed in the fixed shaft sleeves 11 of the balancing machine case 24 and can rotate in the fixed shaft sleeves 11. One of the two fixed shaft sleeves 11 is installed on the rear case 3 and the other is installed on the case vertical plate 9. The electronic lock 6 is fixed to the rear case 3 with the electronic lock fixing screws 7. The limit shaft 10 is fixed on the case vertical plate 9. The other end of the protective cover shaft 12 is welded with a steering plate 5. When the lower limit stop 5-1 and the upper limit stop 5-2 on the steering plate 5 are in contact with the limit shaft 10, they are the two extreme positions of lifting and lowering the protective cover 1, that is, the range in which the protective cover 1 can rotate. The in-place switch 13 is installed on the box body vertical plate 9 with the in-place switch fixing screw 14. The in-place switch block 5-3 of the steering plate 5 can touch the in-place switch 13. The energy storage torsion spring 4 is installed on the protective cover shaft 12. The protective cover shaft 12 rotates and the energy storage torsion spring 4 starts to store energy. When the protective cover 1 is in the raised position, the energy storage torsion spring 4 has a small initial force. The upper limit block 5-2 on the steering plate 5 contacts the limit shaft 10 to ensure the initial stable state of the protective cover bracket 2 when it is lifted. When dynamic balancing of the tire is required, the operator pulls down the protective cover 1, and the energy storage torsion spring 4 is twisted and tightened in the direction of rotation of the protective cover shaft 12 to store energy. The lowered protective cover 1 covers a larger angle range of the upper front of the tire within the arc of the protective cover 1, separating the operator from the rotating tire, effectively protecting the operator. When the lower limit stopper 5-1 of the steering plate 5 contacts the limit shaft 10, the in-position switch stopper 5-3 of the steering plate 5 touches the in-position switch 13 at the same time, starting the electronic lock 6. The electronic lock 6 Action, sucking the steering rod 8, so that the protective cover 1 is stabilized in the lowered working position state, and the detection begins. When the balancing machine detection is completed, the in-place switch 13 group electronic lock 6 issues an unlocking command, releasing the steering rod 8, and the energy storage torsion spring 4 reversely twists. The protective cover 1 is automatically lifted under the reverse force of the energy storage torsion spring 4 until the upper limit stop 5-2 of the steering plate 5 contacts the limit shaft 10. The protective cover 1 is in the initial stable state of lifting, and the measurement is ended for subsequent correction operations to complete a detection process. If an accident occurs during the measurement process or the measurement process needs to be terminated, the manual operation is still valid. When the operator manually lifts the protective cover 1, the in-place switch 13 detects the position change and issues an unlocking command. The protective cover 1 is placed by the operator in the initial position of lifting.
