In some embodiment of the present disclosure, the locking device includes a mounting base, arranged on the movable baffle, and having a mounting cavity formed therein and at least one sliding groove formed on a side wall thereof, wherein one end of the sliding groove faces towards the guide rod; a sliding block, movably mounted in the sliding groove, and having one end extending into the mounting cavity; and a rotating block, rotatably mounted in the mounting cavity, and having at least one convex block protruding outwardly from a side wall of the rotating block; wherein, when the rotating block rotates relative to the mounting base, the convex block is capable of abutting against the sliding block and pushing the sliding block to approach the guide rod along the sliding groove.
In some embodiment of the present disclosure, two sliding grooves are arranged on two opposite sides of the mounting cavity respectively, and one sliding block is movably arranged at each of the sliding grooves; two convex blocks are oppositely arranged on the side wall of the rotating block; and two guide rods are arranged laterally to the two sliding grooves, respectively.
In some embodiment of the present disclosure, the movable baffle is hollow and consisted of a first baffle and a second baffle, the locking device is arranged inside the movable baffle, and the first baffle and/or the second baffle has a notch on a surface thereof at a position corresponding to the locking device; and the movable baffle further comprise a communication opening matched with the guide rod and arranged in a junction surface of the first baffle and the second baffle, and the guide rod is movably inserted into the communication opening.
In some embodiment of the present disclosure, the locking device further includes at least one knob having an insertion portion on one side surface thereof, wherein the insertion portion is attached to the rotating block through the notch, and the knob is capable of moving the rotating block.
In some embodiment of the present disclosure, each of the first baffle and the second baffle has one notch on a surface thereof; and two knobs are mounted at two notches respectively, and both the two knobs are connected with the rotating block.
In some embodiment of the present disclosure, the door guardrail further includes a connecting device arranged between the two knobs for detachably connecting the two knobs.

Referring to
By providing the opening 110 on the door guardrail body 100, and movably mounting the movable baffle 200 on the door guardrail body 100, when a user allows a pet to enter and leave a limited area blocked by the guardrail, the user can move the movable baffle 200 expose the opening 110. In this way, the pet can enter and enter the limited area through the opening 110 without requiring the user to repeatedly open or close the door guardrail, a more convenient operation is achieved.
Referring to
It is conceivable that the movable baffle 200 is also capable of being movable along a width direction of the door guardrail body 100 to open or close the opening 110. Specific arrangements may be determined according to actual needs.
Further, to facilitate the pet to pass through the opening 110, and facilitate the production and assembly of the guardrail door as well, in some embodiments of the present disclosure, the opening 110 is arranged in a middle lower portion of the door guardrail body 100, thus facilitating the pet to pass through the opening 110. At least one guide rod 120 located above the opening 110 is arranged on the door guardrail body 100, and the guide rod 120 is arranged along a vertical direction. The movable baffle 200 is movably mounted on the guide rod 120, and the movable baffle 200 is capable of be movable vertically along the guide rod 120. In this way, the guardrail door can be made simpler and more convenient.
Referring to
To ensure that the locking device is capable of locking the position of the movable baffle 200 relative to the door guardrail body 100, in some embodiments of the present disclosure, two sliding grooves 302 are provided. The two sliding grooves 302 are correspondingly arranged on two opposite sides of the mounting cavity 301, and each sliding groove 302 is movably provided with one sliding block 310. The rotating block 320 is provided with two convex blocks 321 respectively arranged on two opposite side walls of the rotating block 320. Two guide rods 120 are provided, and arranged laterally to the two sliding grooves 302 in one-to-one correspondence. By adopting the structure above, when the user turns the rotating block 320 to rotate, the rotating block 320 can simultaneously drive two sliding blocks 310 to move outwards along sliding grooves 302 respectively to squeeze the guide rods 120, thereby greatly improving the locking force of the locking device to lock the position of the movable baffle 200 relative to the door guardrail body 100, and ensuring that the position of the movable baffle 200 relative to the door guardrail body 100 is unchanged while the locking device is actuated.
Referring to
Further, to enable the user to drive the rotating block 320 to rotate in a better way, in an embodiment of the present disclosure, the locking device further includes at least one knob 330, the knob 330 is provided with a insertion portion 331 on a side surface thereof, the insertion portion 331 is attached to the rotating block 320 through the notch 230. The knob 330 is capable of driving the rotating block 320. In this embodiment, the rotating block 320 is provided with a clamping groove 322 on a surface thereof, and a clamping block (not shown in the figures) matched with the clamping groove 322 is arranged on the insertion portion 331, such that the knob 330 can drive the rotating block 320 to rotate through the clamping block clamped in the clamping groove 322. It is conceivable that the insertion portion 331 may also be connected with the rotating block 320 by means of thread connection, and the specific arrangements may be determined according to actual needs.
Further, each of the first baffle 210 and the second baffle 220 is provided with one notch 230, accordingly two knobs 330 are provided. The two knobs 330 are mounted at the two notches 230 respectively, and the two knobs 330 are both connected with the rotating block 320. By adopting the structure above, the user may control any one of the knob 330 to rotate, that is, may drive the rotating block 320 to rotate and realize the control of the locking device to lock or unlock the position of the movable baffle 200 relative to the door guardrail body 100, which is simpler to operate.
Referring to
It is conceivable that, the locking device may adopt other structures besides the above-mentioned structure. For example, the locking device may include a thread connecting seat (not shown in the figure) arranged on an inner wall of the second baffle 220 and a locking bolt (not shown in the figure) matched with the thread connecting seat. The first baffle 210 has an opening on a surface thereof at a position corresponding to the thread connecting seat. In assembling, the locking bolt is in thread connection with the thread connecting seat through the opening. In use, the user can rotate the locking bolt to drive the first baffle 210 and the second baffle 220 to approach each other and clamp the guide rod 210, thus locking the position of the movable baffle 200 relative to the door guardrail body 100. In unlocking, only the locking bolt needs to be rotated reversely, to cause the first baffle 210 and the second baffle 220 no longer to clamp the guide rod 210. In this way, the movable baffle 200 can be moved.
The embodiments of the present disclosure are described in detail with reference to the drawings above, but the present disclosure is not limited to the above embodiments, and various modifications may be made within the knowledge scope of those of ordinary skills in the art without departing from the purpose of the present disclosure.
