As shown in FIG. 3 to FIG. 7, the telescopic adjusting mechanism 130 includes an operating component 131, a first recovering component 132, a pin component 133, and a telescopic component 134. The telescopic component 134 is movably connected to the bottom of the seat body 110 along a retracting direction. An end of the telescopic component 134 is fixed to the pipe 140. A plurality of holes 1341 is formed on the telescopic component 134 along the retracting direction. The telescopic component 134 is detachably engaged with the pin component 133. The pin component 133 is installed at the bottom of the seat body 110.

The pin component 133 is engaged with one of the plurality of holes 1341 for retraining the telescopic component 134 when the pin component 133 is located at a first position.

The inclined plane 1313 of the operating component 131 is disposed between the seat body 110 and the plate 1332. The operating component 131 is operated to move the inclined plane 1313, such that the plate 1332 is deformed by the inclined pThne 1313, which allows the protruding column 1331 to engage with or disengage from the one of the plurality of holes 1341.

Preferably, the plate 1332 can be a resilient plate and deformed resiliently. The resiliently deformed plate 1332 recovers the protruding column 1331 and further biases the

S

protruding column 1331 to engage with the one of the plurality of holes 1341.

Please refer to FIG. 3 to FIG. 7. In this embodiment, the telescopic adjusting mechanism 130 further includes a connecting component 135 and a bottom pipe 136. The bottom pipe 136 is a hollow structure. The bottom pipe 136 is fixed to the bottom of the seat body 110 along the retracting direction, that is, a front-back direction of the seat body 110. The operating component 131 is slidably conmecred to am outer side of the bottom pipe 136. The plate 1332 is fixed to the outer side of the bottom pipe 136 and cooperatively connected to the inclined plane 1313 disposed at the end of the operating component 131. The protruding columr 1331 is fixed to the plate 1332. A through hole 1362 is formed on the bottom pipe 136 for allowing the protruding column 1331 to pass through. The telescopic component 134 is slidably accommodated in the bottom pipe 136. An end of the telescopic component 134 is fixed to am end of the connecting component 135. The other end of the connecting component 135 is fixed to the pipe 140. The plurality of holes 1341 is formed on the telescopic component 134 along the retracting direction. The protruding column 1331 slidably passes through the through hole 1362 to engage with the one of the plurality of holes 1341. Meantime, the protruding column 1331 is at the first position for positioning the telescopic component 134. When the operating component 131 is operated, the operating component 131 pushes the plate 1332 to be resiliently deformed, so as to drive the protruding column 1331 on the plate 1332 to disengage from the one of the plurality of holes 1341 of the telescopic component 134. Meantime, the protruding column 1331 is at the second position, and the mounting component cam be adjusted im the telescopic manner.

Preferably, the connecting component 135 can be made of plastic material. An end of the connecting component 135 is fixed on the end of the telescopic component 134. The other end of the connecting component 135 is sleeved on the pipe 140. The connecting component 135 is not limited to the above-mentioned embodiment.

Please refer to FIG. 3 to FIG. 5. An operating end 1311 is formed at the other end of the operating component 131.

A driving end 1312 is formed at the end of operating component 131. The inclined plane 1313 is disposed at the driving end 1312. After the operating component 131 is connected to the bottom pipe 136, the operating end 1311 is adjacent to a front end of the seat body 110, and the driving end 1312 is adjacent to a back end of the seat body 110. The inclined plane 1313 and the plate 1332 are cooperatively connected. The operating component 131 is driven to slide along the retracting direction by operating the operating end 1311, such that the inclined plane 1313 pushes the plate 1332 to be resiliently deformed, which drives the protruding colllmn 1331 to disengage from the one of the plurality of holes 1341 of the telescopic component 134. Therefore, the telescopic component 134 can be retracted by pushing or pulling the pipe 140, so as o adjust the mounting component 150 in the telescopic manner.

Specifically, a restraining slot 1361 is formed on the bottom pipe 136 along the retracting direction. The operating component 131 is slidably accommodated in the retraining slot 1361. A fixing portion 1333 is formed at an end of the plate 1332. The plate 1332 is fixed at an end of the bottom pipe 136 adjacent to the back end of the seat body 110 by the fixing portion 1333. The plate 1332 extends toward the front end of the seat body 110. The plate 1332 covers the restraining slot 1361 of the bottom pipe 136 and corresponds to the inclined plane 1313 of the operating component 131.

Please refer to FIG. 5 to FIG. 7. The inclined plane 1313 is disposed between the bottom pipe 136 and the plate 1332.

A driven inclined plane 1334 cooperating with the inclined plane 1313 is disposed on the plate 1332. After the cperating component 131 is installed, the driving end 1312 is inserted between the plate 1332 and the bottompipe 136, and the inclined plane 1313 is opposite to the driven inclined plane 1334.

Therefore, when the operating end 1311 is operated to allow the operating component 131 to slide along the retraining slot 1361, i.e., when the operating component 131 slides along the retracting direction, the inclined plane 1313 pushes the driven inclined plane 1334 to move the plate 1332, such that the protruding column 1331 is driven to move along the actuating direction and disengage from the one of the plurality holes 1341 on the telescopic component 134. Amoving direction of the protruding column 1331 can be substantially perpendicular to a moving direction of the operating component 131, i.e., the actuating direction can be substantially perpendicular to the retracting direction, which allows the mounting component 150 to be adjusted in the telescopic manner.

Since the plate 1332 is made of resilient material and can be resilient deformed, the plate 1332 can be recovered by its resilience after the inclined plane 1313 is released, so as to drive the protruding column 1331 to engage with another one of the plurality of holes 1341 and bias the protruding column 1331 to engage with the another one of the plurality of holes 1341.

Please refer to FIG. 4 to FIG. 7. As shown in FIG. 7, the protruding column 1331 includes a positioning rib 1331a perpendicularly extended from a middle portion of the protruding column 1331. An installing hole 1335 is formed at a location on the plate 1332 away from the fixing portion 1333.

An end of the protruding column 1331 is accommodated in the installing hole 1335. A side of the positioning rib 1331a abuts against the driven inclined plane 1334. The other side of the positioning rib 1331a abuts against the driving end 1312. The other end of the protruding column 1331 passes through the through hole 1362 on the bottom pipe 136 to engage with the one of the plurality of the holes 1341 of the telescopic component 134.

In this embodiment, the plurality of holes 1341 is evenly formed on the telescopic component 134 along the retracting direction. The protruding column 1331 can be detachably engagedwithanyone of thepluralityof holes 1341. Therefore, when the operating end 1311 of the operating component 131 is operated, the operating component 131 slides and drives the inclined plane 1313 to push the driven inclined plane 1334, such that the plate 1332 is resiliently deformed. The resiliently deformed plate 1332 drives the protruding column 1331 thereon to disengage from the one of the plurality of holes 1341 on the telescopic component 134, so as to allow the mounting component 150 to be adjusted in the telescopic manner. During the above-mentioned process, the plate 1332 is resiliently deformed. After adjustment of the mounting component 150 is completed and the operating end 1311 is released, the plate 1332 is recovered by its resilience, such that the protruding column 1331 is re-engaged with another one of the plurality of holes 1341 on the telescopic component 134, for positioning the mounting component 150.

Furthermore, in this embodiment, the first recovering component 132 can be an extension spring. Two ends of the spring are connected to the operating end 1311 and the other end of the bottom pipe 136, respectively, as shown in FIG. 6. In such a way, the spring is extended to generate a recovering force when the operating end 1311 is operated. The spring is recovered and recovers the operating component 131 when the operating end 1311 is released, such that the inclined plane 1313 does not push the driven inclined plane 1334, which drives the protruding column 1331 to re-engage with another one of plurality of holes 1341 and biases the protruding column 1331 to engage with the another one of the plurality of holes 1341.

Please refer to FIG. 1 to FIG. 7. The adjusting process and principle of the child safety seat 100 are described as follows. After the child safety seat 100 is installed on a vehicle, such as a car seat, the mounting component 150 of the child safety seat 100 is fixed into an anchoring component of the vehicle. A child is fastened to the child safety seat by fastening eguipment, so as to protect the child.

When it is required to adjust a relative position between the child safety seat 100 and the vehicle, the operating end 1311 of the operating component 131 is to be operated, such that the operating component 131 slides along the restraining slot 1361 on the bottom pipe 136. The moving direction of the operating component 131 is substantially parallel to the moving direction of the vehicle. During the above-mentioned process, the inclined plane 1313 of the driving end 1312 pushes the driven inclined plane 1334 on the plate 1332, such that the plate 1332 is resiliently deformed and drives the protruding column 1331 to disengage from the one of the plurality of holes 1341 on the telescopic component 134. The moving direction of protruding column 1331 is substantially perpendicular to the moving direction of the operating component 131. Meantime, the pipe 140 can be pushed or pulled to adjust the mounting component 150 in the teiescopic manner.

During the process that the operating end 1331 is operated, the spring is extended. After adjustment of the mounting component 150 is completed, the operating end 1311 is released, and the spring is recovered and drives the operating component 131 to be recovered, such that the inclined plane 1313 does not push the driven inclined plane 1334. Meantime, the plate 1332 is recovered by its resilience and drives the protruding column 1331 to engage with the corresponding one of the plurality of holes 1341, so as to position the telescopic component 134 and complete adjustment of the mounting component 150.

Two ends of the pipe 240 are fixed to two mounting components 250, respectively. The telescopic component 234 is detachably engaged with the pin component 233. The pin component 233 is engaged with one of the plurality of holes 2342 for restraining the telescopic component 234 when the pin component 233 is at a first position. The pin component 233 is disengaged from the one of the plurality of holes 2342 for releasing the telescopic component 234 when the pin component 233 is located at a second position. The operating component 231 is slidably connected to the bottom of the seat body 210. An inclined plane 2314 abutting against the pin component 233 is disposed at an end of the operating component 231. The operating component 231 is operated to move the inclined plane 2314, such that the pin component 233 is driven to shift between the first position and the second position along an actuating direction intersecting the retracting direction by the inclined plane 2314. The second recovering component 232 is for recovering the operating component 231.

Furthermore, in this embodiment, the telescopic adjusting mechanism 230 further includes a connecting component 235.

An end of the connecting component 235 is fixed to an end of the telescopic component 234. The other end of the connecting component 235 is fixed to the pipe 240. Preferably, the connecting component 235 can be made of plastic material.

However, the connecting component 235 is not limited to this embodiment and can be other connecting mechanism.

Please refer to FIG. 9 to FIG. 12. An operating end 2311 is formed at an end of the operating component 231. A driving end 2312 is formed at the other end of the operating component 231, and the inclined plane 2314 is disposed at the driving end 2312. After the operating component 231 is connected to the bottom of the seat body 210, the operating end 2311 is adjacent to a front end of the seat body 210, and the driving end 2312 is adjacent to a back end of the seat body 210. The inclined plane 2314 of the driving end 2312 and the pin component 233 are connected cooperatively. The operating component 231 is driven to move along the retracting direction by operating the operating end 2311, such that the inclined plane 2314 of the driving end 2312 drives the pin component 233 to move and disengage from the one of the plurality of holes 2342, which allows the mounting component 150 to be adjusted by pushing or pulling the pipe 240.

Specifically, a side of the telescopic component 234 slidably contacts with the bottom of the seat body 210. An accommodating zone 2341 is formed at a middle portion of the other side of telescopic component 234 along the retracting direction. The operating component 231 is slidably accommodated in the accommodating zone 2341, such that the operating end 2311 is adjacent to the front end of the seat body 210, and the driving end 2312 is adjacent to the back end of the seat body 210.

More specifically, an inclined slot 2313 is formed at the driving end 2312. The inclined plane 2314 is formed on an inner wall of the inclined slot 2313. The pin component 233 is inserted into the inclined slot 2313. The operating component 231 is driven to move by operating the operating end 2311, such that the inclined plane 2314 drives the pin component 233 to engage with or disengage from the one of the plurality of holes 2342.

Please refer to FIG. 10 to FIG. 12. In this embodiment, the second recovering component 232 can be a spring.

Accordingly, an accommodating slot 2315 is formed at a location on the operating component 231 near the operating end 2311. The accommodating slot 2315 includes a protrusion 2316 at a side wall away from the operating end 2311. The spring is accommodated in the accommodating slot 2315. An end of the spring is sleeved on the protrusion 2316 and abuts against the side wall. The other end of the spring abuts against the bottom of the seat body 210. In such a way, the operating component 231 slides along the retracting direction when the operating component 231 is operated. The inclined plane 2314 of the driving end 2312 drives the pin component 233 to slide, such that the pin components 233 disengages from the one of the plurality of holes 2342, which allows the mounting component 250 to be adjusted in the telescopic manner. Amoving direction of the pin component 233 is substantially perpendicular to a moving direction of the operating component 231, i.e., the moving direction of the pin component 233 is substantially perpendicular to the retracting direction.

During the process that the operating component 231 is recovered, the third resilient component 236 is recovered and further drives the pin component 233 to re-engage with another one of the plurality of holes 2342, so as to bias the pin component 233 to engage with the another one of the plurality of holes 2342. Preferably, the third resilient component 236 is a spring but not limited to hereto.

Please refer to FIG. 8 to FIG. 12. The adjusting process and principle of the child safety seat 200 are described as follows. The installation of the child safety seat 200 in the second embodiment is similar to the installation of the child safety seat 100 in the first embodiment. However, when it is reguired to adjust a relative position between the child safety seat 200 and a vehicle, the operating end 2311 of the operating component 231 is to be operated, such that the operating component 231 slides along the accommodating zone 2341 on the telescopic component 234, i.e., the operating component 231 slides along the retracting direction. During this process, the inclined slot 2313 of the driving end 2312 drives the pin component 233 to slide, such that the two ends of the pin component 233 disengage from the corresponding holes 2342 of the telescopic component 234, which allows the mounting component 250 to be adjusted in the telescopic manner by pushing or pulling the pipe 240.

During the process that the operating end 2311 is operated, the second recovering component 232 is compressed. When adjustment of the mounting component 250 is completed, the operating end 2311 is released. The second recovering component 232 is recovered and drives the operating component 231 to recover, such that the inclined slot 2313 of the driving end 2312 re-drives the pin component 233 to slide and engage with the corresponding holes 2342 and further to bias the pin component 233 to engage with the corresponding holes 2342.

During the process that the pin component 233 slides and the two ends of the pin component 233 disengage from the holes 2342, the third resilient component 236 is compressed. During the process that the operating component 231 is recovered, the third resilient component 236 is recovered and further drives the pin component 233 to re-engage with the corresponding holes 2342, so as to position the telescopic component 234 and complete adjustment of the mounting component 250. The third resilient component 236 biases the pin component 233 to engage with the holes 2342.

In contrast to the prior art, the child safety seat of the present invention includes the seat body, the mounting component, and the telescopic adjusting mechanism. The telescopic adjusting mechanism is disposed between the seat body and the mollnting component for adjusting the mounting component relative to the seat body in a telescopic manner.
