Referring to Fig. 1 , a guardrail grille includes a trunk 100, a top cover and a bottom cover 300, wherein the top cover is connected to the top side of the trunk 100, and the bottom cover 300 is connected to the bottom side of the trunk 100. The top cover or the bottom cover 300 is provided with screw holes 230 , or both the top cover and the bottom cover 300 are provided with screw holes 230 , and the screw holes 230 extend along the length direction of the trunk 100 .

It can be known from the above that the guardrail grille is mainly assembled by the backbone 100, the top cover and the bottom cover 300. When in use, the backbone 100, the top cover and the bottom cover 300 can be made of different materials to form different appearance effects, and more Good control of production costs, for example, the top cover and bottom cover 300 are used as the main connection and fixing structure, and materials with sufficient rigidity are used, while the backbone 100 is used as a transitional connection structure, which can reduce the requirements for material selection, and form a stable structure in this way overall structure, and screw holes 230 are provided on the top cover or bottom cover 300, or on the top cover and bottom cover 300, and screws can be driven into the screw holes 230 to conveniently install and fix the whole on the external device. Structurally, therefore, the utility model is more flexible in use and can be matched with a variety of appearances, which greatly improves the overall practicability and production efficiency.

The screw hole 230 is an internal thread structure protruding on the profile for screwing in. It can be understood as two arc-shaped plates extending around the same center line, and there is a gap between the extended ends of the two plates A screw hole 230 is formed between the two arc-shaped plates. In this embodiment, the screw hole 230 is located on the side of the top cover facing the trunk 100, and the top side of the trunk 100 An avoidance groove 110 is provided, and the screw hole 230 is inserted into the avoidance groove 110 . The top cover is provided with a screw hole 230 for screwing in, and the top side of the trunk 100 is provided with an avoidance groove 110 for receiving the screw hole 230. When the top cover is connected to the top side of the trunk 100, the top cover The protruding screw hole 230 is partially inserted into the avoidance groove 110, which improves the tightness of the connection between the top cover and the trunk 100, making the connection between the two more stable.

For the connection of the top cover to the trunk 100, there are various connection structures, such as direct welding, riveting or screw connection, and in this embodiment, the top cover is detachably connected to the trunk 100, specifically, the top The cover includes a flat plate 210, hook plates 220 connected to the front and rear sides of the flat plate 210, the two hook plates 220 extend downwards, and the bottom ends of the two hook plates 220 are bent to form mutually facing The hook bars 221 are provided with hook grooves on the front and rear sides of the trunk 100 , and the two hook bars 221 are matched and connected in the two hook grooves respectively. When the top cover is connected to the backbone 100, the hook plates 220 on the front and rear sides of the flat plate 210 are respectively extended to the front and rear sides of the top of the backbone 100 to cover the top of the backbone 100, and then the bottom ends of the two hook plates 220 are bent to form hooks. The strips 221 are connected respectively in the two hook grooves on the front and rear sides of the trunk 100. The fastening of the hook strips 221 and the hook grooves can restrict the top cover from coming out of the trunk 100, thereby realizing the quick assembly of the top cover and the trunk 100.

In the above-mentioned embodiment, the size of the avoidance groove 110 on the trunk 100 can be set larger. When the screw hole 230 enters the avoidance groove 110, it is enough that the avoidance groove 110 has enough space to accommodate the screw hole 230. In this embodiment, The outer wall of the screw hole 230 is against the inner wall of the escape groove 110 . The screw hole 230 is attached to the inner wall of the avoidance groove 110, so that the top cover is more closely connected with the trunk 100, and the arc-shaped convex structure of the screw hole 230 itself can form a snap-fit structure when entering the avoidance groove 110, so that the top cover There is also connection and cooperation between the middle part and the trunk 100 , which further improves the stability of the top cover being connected to the trunk 100 .

In this embodiment, the bottom cover 300 and the top cover are vertically symmetrical. Bottom cover 300 is also provided with screw holes 230, which can be quickly clamped and connected to the main body 100. During installation, screws can be driven into the screw holes 230 on the bottom cover 300 and the top cover at the same time to fix them to the structure of the peripheral In this way, the bottom cover 300 and the top cover clamp and fix the trunk 100, so that the overall installation is more stable. The hook plates all extend upwards, and the two hook plates and the flat plate are also surrounded to form an upward-opening frame, which can be directly sleeved on the bottom of the trunk 100, and the bottom ends of the two hook plates are bent to form mutually facing Hook strips, the front and rear sides of the bottom of the trunk are provided with hook grooves, and the two hook strips are respectively matched and connected in the two hook grooves, so as to be clamped and fixed on the bottom of the trunk 100, the bottom cover 300 and the top cover The structure is the same, which reduces the pressure of mold opening and inventory, and better improves economic benefits.

The trunk 100 can be a solid structure or a hollow structure. For example, in this embodiment, a hollow channel 120 is provided in the trunk 100 , and the hollow channel 120 extends along the length direction of the trunk 100 . The hollow channel 120 can reduce the weight and cost of the trunk 100, and better improve production efficiency.

Further, the trunk 100 is made of transparent material. The transparent backbone 100 can reduce the shading of the line of sight when installed on the window frame 400, so that two parallel sidelines remain for the whole guardrail grille in visual observation, further improving the overall appearance.

For example, the top cover and the bottom cover 300 serve as the main connection support structure, in this embodiment, the top cover and the bottom cover 300 are both made of metal. The metal top cover and bottom cover 300 have a certain structural strength, which can better ensure the structural stability when installed on the window frame 400 .

A guardrail, comprising a window frame 400 and the above-mentioned guardrail grating, the guardrail grating extending in the left and right direction is a horizontal grating 410, and the horizontal grating 410 is arranged at intervals in the upper and lower directions in the window frame 400 There are more than one.

As shown in Figure 2, in the first embodiment, the guardrail grilles extending in the left and right directions are connected to the two side walls of the window frame 400, and a plurality of them are arranged at intervals along the up and down directions to form a grille protection structure, thereby improving Anti-theft and safety performance of the window frame 400. In practical applications, the guardrail grille can also be connected to the inner top side and the inner bottom sidewall of the window frame 400 along the vertical direction, and can also form a grille protection structure.

As shown in Figure 3, in the second embodiment, the guardrail grids extending in the up and down direction are vertical grids 420, and the vertical grids 420 are connected between two adjacent horizontal grids 410 . The vertical grid bar 420 and the horizontal grid bar 410 are both guardrail grid bars, which are different from the horizontal grid bar 410 extending in the left and right directions. The space is surrounded by a square. When in use, it is convenient to avoid the handle of the window sash. In practical applications, a horizontal grid bar 410 is also connected to the vertical grid bar 420. The end of the horizontal grid bar 410 away from the vertical grid bar 420 is Connected to the window frame 400.

The preferred embodiments of the present utility model have been specifically described above, but the present invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent modifications or modifications without violating the spirit of the present utility model.
