[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Please refer to the attached Figures 1 to 6 As shown, a guardrail for building doors and windows in an embodiment of the utility model comprises an outer frame 1, both ends of the outer frame 1 are fixedly connected with storage boxes 2, the upper and lower sides between the outer frame 1 and the two storage boxes 2 are fixedly connected with slide rails 4, and two symmetrically arranged folding frames 5 are slidably connected between the two slide rails 4. When in use, the folding frame 5 can move along the slide rail 4, so as to be unfolded and folded. After the folding frame 5 is folded, it can be stored in the storage box 2, thereby minimizing the obstruction of the view outside the window, avoiding the folding frame 5 from obstructing the view inside the house, and reducing the sense of oppression in the room after the guardrail is installed.

[0032] The folding fence 5 includes a main frame body 51 and a plurality of sub-frame bodies 52 , and a plurality of scissor-type brackets 53 are hingedly connected between the main frame body 51 and the plurality of sub-frame bodies 52 .

[0033] A locking mechanism 6 is provided inside the main frame 51, and the locking mechanism 6 includes a slide groove 61 and a lock head 64. The lock head 64 is fixedly connected to one main frame 51 and inserted into the other main frame 51. The slide groove 61 is opened on the upper side of the rear end surface of the main frame 51 away from the lock head 64. An unlocking push block 63 is slidably connected to the lower side of the inner part of the slide groove 61. An outer pull plate 62 is rotatably connected to the upper side of the slide groove 61. The lower end of the outer pull plate 62 contacts the unlocking push block 63. The locking mechanism 6 also includes a pull rod 65. A locking rod 67 is slidably sleeved on the lower end of the pull rod 65. A locking hole 641 is opened on the upper side of the lock head 64. The locking rod 67 is plugged into the locking hole 641. The upper end of the pull rod 65 extends into the slide groove 61 and is fixedly connected to the push block 63.
