- Claim:
1. A misuse preventing mechanism disposed on a rotatable child safety seat, the rotatable child safety seat having a base and an installation bracket coupled to the base and configured to support a carrier body, the installation bracket being capable of rotating with respect to the base and having a restraining groove, and the misuse preventing mechanism comprising a lock member disposed on the base and driven to extend into the restraining groove to restrain a rotation angle of the carrier body, wherein the misuse preventing mechanism further comprises a driving assembly disposed on the base, the driving assembly being adapted to drive the lock member to extend into the restraining groove, and drive the lock member to eject from the restraining groove; and wherein the driving assembly comprises an operating member, a linkage member, and a guiding pillar, the operating member is pivotally connected to the linkage member, a pivot joint between the operating member and the linkage member slides along an arc hole about the guiding pillar, such that rotation of the operating member drives the lock member to move along a length direction of the lock member.
- Claim:
2. The misuse preventing mechanism of claim 1 , wherein the restraining groove has a first end and a second end; and when the lock member is driven to extend into the restraining groove, the rotation angle of the carrier body is restrained within an angle included between the first end and the second end of the restraining groove.
- Claim:
3. The misuse preventing mechanism of claim 1 , wherein an end of the linkage member is pivotally connected to the operating member, another end of the linkage member is pivotally connected to the lock member, the lock member has a first guiding hole, a middle portion of the linkage member has a second guiding hole, the guiding pillar is fixed on the base, the guiding pillar is inserted into the first guiding hole and the second guiding hole, and the operating member is operated to cause the linkage member to swing under guidance of the guiding pillar and drive the lock member to extend into or eject from the restraining groove under guidance of the guiding pillar.
- Claim:
4. The misuse preventing mechanism of claim 3 , wherein the operating member is disposed on an outer surface of the base, the linkage member and the lock member are disposed in the base, the base has the arc hole, and the linkage member is pivotally connected to the operating member through a third guiding hole.
- Claim:
5. The misuse preventing mechanism of claim 4 , wherein a center of the arc hole corresponds to the guiding pillar.
- Claim:
6. The misuse preventing mechanism of claim 4 , wherein the operating member is a knob.
- Claim:
7. The misuse preventing mechanism of claim 3 , wherein the first guiding hole is a longitudinal hole.
- Claim:
8. The misuse preventing mechanism of claim 3 , wherein the second guiding hole is an arc hole and a center of the arc hole corresponds to a pivot joint between the linkage member and the operating member.
- Claim:
9. The misuse preventing mechanism of claim 3 , wherein the base has an extension hole and the lock member extends into or ejects from the restraining groove through the extension hole.
- Claim:
10. The misuse preventing mechanism of claim 1 , wherein the misuse preventing mechanism further comprises an elastic member and the elastic member provides an elastic force for extending the lock member into the restraining groove.
- Claim:
11. The misuse preventing mechanism of claim 1 , wherein the misuse preventing mechanism further comprises an elastic member and the elastic member provides an elastic force for ejecting the lock member from the restraining groove.
- Claim:
12. A rotatable child safety seat comprising a carrier body, a base, and an installation bracket capable of supporting the carrier body and rotating with respect to the base, the rotatable child safety seat further comprising the misuse preventing mechanism of claim 1 , the misuse preventing mechanism being disposed between the carrier body and the installation bracket, and a rotation range of the carrier body with respect to the installation bracket being adjusted by the misuse preventing mechanism.
