Claims (24)

1 . An adjustable protector, comprising:

a fixing seat;

a sliding portion slidably arranged on the fixing seat,

a locking mechanism arranged between the fixing seat and the sliding portion to lock or unlock the sliding portion;

one of the fixing seat and the sliding portion is provided with a guide groove having a first major elongate surface extending along a first direction ascending from back to front on a first side surface thereof; and

the other of the fixing seat and the sliding portion is provided with a guide rail having a second major elongate surface extending along a second direction ascending from back to front on a second side surface thereof, and the guide groove slidably fits with the guide rail,

wherein the seat body comprises a connecting rod, and the fixing seat comprises a fastening mechanism disposed at an end of the fixing seat and configured to detachably connect to the connecting rod, and

wherein, when the sliding portion slides forward from back to front, the sliding portion is configured to slide along an ascending direction that is parallel to the first direction and the second direction and non-parallel to a longitudinal axis of a seat body of a safety seat.

2 . The adjustable protector of claim 1 , wherein the guide groove is a sliding pipe, the guide rail is a fixing pipe, and the sliding pipe is slidably sleeved outside the fixing pipe.

3 . The adjustable protector of claim 1 , wherein the locking mechanism comprises an engaging rod slidably arranged on the sliding portion, the fixing seat comprises at least two engaging holes along a direction ascending from back to front, and the engaging rod is selectively inserted into any one of the engaging holes.

4 . The adjustable protector of claim 3 , wherein the locking mechanism comprises a driving block, the driving block is slidably arranged on the sliding portion and has a sliding direction intersecting with a sliding direction of the engaging rod;

the driving block comprises a driving chute, and

a sliding pin is fixedly arranged on one end of the engaging rod and is slidably inserted into the driving chute.

5 . The adjustable protector of claim 4 , wherein the locking mechanism comprises an operating member connected to the driving block.

6 . The adjustable protector of claim 4 , wherein the locking mechanism comprises an elastic element which provides an elastic force for inserting the engaging rod into the engaging hole.

7 . The adjustable protector of claim 3 , wherein the locking mechanism comprises an operating member, and the operating member is connected to the engaging rod and is slidably arranged in the sliding portion.

8 . The adjustable protector of claim 7 , wherein the sliding portion comprises a guide rod, and the operating member is slidably sleeved on the guide rod.

9 . A safety seat comprising a seat body and an adjustable protector, wherein the adjustable protector comprises a fixing seat, a sliding portion slidably arranged on the fixing seat, and a locking mechanism arranged between the fixing seat and the sliding portion to lock or unlock the sliding portion, and

one of the fixing seat and the sliding portion is provided with a guide groove having a first major elongate surface extending along a direction ascending from back to front on a first side surface thereof,

the other of the fixing seat and the sliding portion is provided with a guide rail having a second major elongate surface extending along a second direction ascending from back to front on a second side surface thereof, and the guide groove slidably fits with the guide rail,

wherein the seat body comprises a connecting rod, and the fixing seat comprises a fastening mechanism disposed at an end of the fixing seat and detachably connected to the connecting rod,

wherein, when the sliding portion slides forward from back to front, the sliding portion is configured to slide along an ascending direction that is parallel to the first direction and the second direction and non-parallel to a longitudinal axis of the seat body.

10 . The safety seat of claim 9 , wherein the fastening mechanism comprises an engaging hook, a reinforcing member and a push button, the reinforcing member is fixed on the fixing seat and comprises an opening, the engaging hook is pivotally connected to the fixing seat, and the push button is slidably arranged on the fixing seat and is capable of pushing the engaging hook to swing, so as to close or open the opening by the engaging hook.

11 . The safety seat of claim 10 , wherein the fastening mechanism comprises a reset elastic member arranged between the fixing seat and the locking hook and providing an elastic force for driving the locking hook to be rotated to a position of closing the opening.
