In order to prevent infants and pets, when going outdoors, from getting lost or injured, retractable door fences are often provided for indoor doors, stairwells, or corridors.
The Chinese patent application number CN202320165782.9, for example, discloses an adjustable retractable protective door fence, mainly including components such as upper and lower supports, roller shutter components, and a roller. The roller can be pivotally installed between the upper and lower supports, and the roller shutter can be installed on the roller and pulled out for use. When the roller shutter is not in use, the elastic torque of the spring can drive the roller to rotate and retract the roller shutter. The free end of the roller shutter (i.e. the end away from the roller) is provided with two hooks, which are vertically spaced apart. After the installation of the retractable door fence, two buckles have to be installed in another installation position and need to maintain a height consistent with that of the two hooks. After the roller shutter is pulled out, the two buckles can be connected with the two hooks to fix the roller shutter and, the buckles and hooks can be disconnected to retract the roller shutter.
It is very troublesome to install buckles because two buckles are usually used to maintain the flatness of the roller shutter, which need to be positioned and installed according to the height and position of the hooks. After the installation of the buckles, a height difference will often occurs between the hooks and the buckles, causing the buckles to be misaligned and unable to be fastened, and the buckles must be repositioned and installed.

Specifically, the free end of the roller shutter 4 can be detachably connected to the column 5 or the connecting base. In the embodiment in which the free end of the roller shutter 4 is detachably connected to the column 5, the free end of the roller shutter 4 is provided with a hook that fits the column 5. After the roller shutter 4 is pulled out, the free end of the roller shutter 4 can be fixed through the fit coordination between the hooks and the hook of the column 5. In order to strengthen the connection between the free end of the roller shutter 4 and the connecting mechanism, and avoid easy separation between the hook and the column 5, the locking structure in the prior art, such as screw, buckle structure, can be used to lock the hook and column 5 after the hook is connected to column 5, thus the specific structural principle of such structures is not elaborated here. Of course, in this embodiment, the hook can also be replaced by items such as straps, buckles, and ropes with Velcro.
In this embodiment, the free end of roller shutter 4 is detachably connected to the connecting base: the free end of the roller shutter 4 is provided with a support rod 41, and the base includes an upper connecting base 6 and a lower connecting base 7 respectively disposed at the top and bottom of the column 5, a first slot 6 for the top of the support rod 41 to be inserted and a second slot 71 for the bottom of the support rod 41 to be inserted are respectively formed at the bottom of the upper connecting base 6 and on the top of the lower connecting base 7, the locking mechanism is used to lock the support rod 41 with the base after the top and bottom of the support rod 41 are inserted into the first slot 61 and the second slot 71, respectively.
Specifically, the upper connecting base 6 and the lower connecting base 7 are integrated with the column 5 or are detachable connecting structures. In case of detachable connecting structures, the upper connecting base 6 and the lower connecting base 7 are respectively inserted into the top and bottom ends of the column 5 and locked by screws or fixed by a buckle structure.
Specifically, the locking mechanism includes a first slider 81, a vertically extended accommodating groove 60 that fits the first slider 81 on the top wall of the first slot 61, and the first slider 81 is movably installed in the accommodating groove 60 and can perform vertical reciprocating motion relative to the accommodating groove 60.
In an embodiment, the top of the support rod 41 is provided with a locking hole, and after the top of the support rod 41 is inserted into the first slot 61, the locking hole is aligned up and down with the first slider 81. To install the support rod 41, first insert the bottom end of the support rod 41 into the second slot 71, and then clip the top end of the support rod 41 into the first slot 61, aligning the locking hole with the first slider 81 up and down, and then the first slider 81 descends and the lower end of the first slider 81 inserts into the locking hole, so that the top of the support rod 41 cannot exit the first slot 61, thereby locking the top of the support rod 41 with the upper connection base 6. In further, because the top of the support rod 41 is locked, the bottom end of the support rod 41 cannot exit the second slot 71, thus locking the support rod 41 with the base. When the first slider 81 rises, the lower end of the first slider 81 will exit the locking hole, releasing the locking between the support rod 41 and the base. In this embodiment, the first slider 81 is quite long. As for how to drive the first slider 81 to perform vertical reciprocating motion in this embodiment, a driving component connected to the first slider 81 can be provided on the upper connecting base 6, and the driving component can be manually controlled to drive the first slider 81 to perform vertical reciprocating motion. Of course, reference can also be made to the driving structure in prior art, which will not be further elaborated here.
In this embodiment, a locking element 82 is movably provided at the top of the support rod 41, and the locking element 82 can move between the positions where the locking element 82 retracts into the support rod 41 and extends into the accommodating groove 60 to force the first slider 81 is to move upward, the support rod 41 is internally provided with a first top spring 83 that is connected to the locking element 82, and through the first top spring 83, elastic force is applied to the locking element 82 to force the first slider 81 to move upward. To install the support rod 41, first insert the bottom end of the support rod 41 into the second slot 71, and then clip the top end of the support rod 41 into the first slot 61. External force, such as manual pressing, can be used to force the locking element 82 into the interior of the support rod 41, and at the same time, clip the top end of the support rod 41 into the first slot 61, or during the clipping process, the pressure generated by the contact between the outer wall of the upper connecting base 6 and the locking element 82 can force the locking element 82 to automatically retreat into the interior of the support rod 41, and the top of the support rod 41 is clipped into the first slot 61, the external force applied to the locking element 82 disappears. The elastic force of the first top spring 83 forces the locking element 82 to extend into the accommodating groove 60 and lift the first slider 81. The locking element 82 located in the accommodating groove 60 can restrict the top of support rod 41 from exiting the first slot 61, thereby locking the upper end of support rod 41 with the upper connecting base 6. In further, because the top end of the support rod 41 is being locked, the bottom end of the support rod 41 cannot exit the second slot 71, thus locking the support rod 41 with the base. The first slider 81 descends to contact and force the locking element 82 to retreat into the interior of the support rod 41. After the top of the support rod 41 is released, the top of the support rod 41 can be taken out of the first slot 61 and the bottom of the support rod 41 can be taken out of the second slot 71, so that the support rod 41 and the connecting mechanism are disassembled.
