DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present invention in detail with reference to specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example 1

[0025] refer to Figures 1 to 4 A window with a guardrail comprises a window body and a guardrail body. The window body comprises a top frame 100 and a bottom frame 200 at the upper and lower ends, and two side frames 1 connecting the top frame 100 and the bottom frame 200. The guardrail body comprises a plurality of guardrail rods 2 arranged in parallel at equal intervals. The two ends of each guardrail rod 2 are axially welded and fixed to a connecting plate 3. The side frame 1 comprises a base 11, an outer extension portion 12 extending from the base 11 to one side, and an inner extension groove 13 arranged opposite to the outer extension portion 12 for embedding the connecting plate 3. The connecting plate 3 on one side is hinged and fixed by a plurality of hinges (not shown in the figure), and a clamping mechanism for clamping and mounting with the side frame 1 is installed on the connecting plate 3 on the other side. When the side with the hinge is installed, the installation position of the connecting plate 3 can be adjusted by adjusting the installation height of the hinge to ensure that it can be rotated along the hinge position to open.

[0026] Structurally, the locking mechanism includes a special-shaped locking piece 4 located at the top end of the frame 1. The special-shaped locking piece 4 is made of a metal sheet with a certain degree of elasticity, and includes a locking end 41, a main body 42 and a connecting end 43 hinged on the connecting plate 3. The main body 42 has an arc-shaped contact surface 44, and the connecting plate 3 is screwed with a contact screw 45 that is adapted to the arc-shaped contact surface 44; the top frame 100 is provided with a locking groove 101 that is adapted to the locking end 41. When the special-shaped locking piece 4 is in a relaxed state, the locking end 41 is separated from the locking groove 101; when the contact screw 45 extends into the frame 1, the contact screw 45 squeezes the arc-shaped contact surface 44 to make the locking end 41 extend into the locking groove 101. The interference screw 45 is a countersunk screw. After the interference screw 45 is installed, it is parallel to the surface of the connecting plate 3 and does not protrude from the connecting plate 3 in appearance. Its end portion presses against the arc-shaped interference surface 44 as the screw connection deepens, and then the main body 42 is pushed up as a whole, so that the clamping end 41 penetrates into the clamping groove 101 on the top frame 100, thereby clamping the connecting plate 3 inside; a rubber strip (not shown in the figure) is inserted into the inner extension groove 13 on this side to fill the gap, so as to prevent shaking, improve the regularity of the appearance of the guardrail, and provide certain protection for the clamping mechanism.

[0027] This technical solution is aimed at improving the traditional windows with large size. In the design of the guardrail, a relatively light structure is adopted. The two sides of the guardrail rod 2 are fixed on the connecting plate 3, and then a structure is adopted in which the connecting plate 3 on one side is hinged and the connecting plate 3 on the other side is clamped. When needed, the clamping mechanism is opened and the guardrail rod 2 is rotated to complete the emergency opening. In terms of appearance, the clamping mechanism is located inside the connecting plate 3 and the frame 1. The appearance is no different from that of a traditional window with a guardrail. Criminals cannot judge the locking position based on the appearance, which also improves the anti-theft performance to a certain extent. Children at home cannot The guardrail is simply opened to ensure the protective effect; structurally, it also improves the traditional guardrail rod 2 directly welded to the window frame on both sides or directly fixed installation form, and the guardrail rod 2 is welded to the connecting plates 3 on both sides in production as a whole, and then the connecting plates 3 are accommodated and wrapped by the frame 1. This structure can adjust the position of the connecting plate 3 in the extension groove 13 in the frame 1 during installation, and then fine-tune the installation position of the guardrail, with good installation flexibility, and the inner extension groove 13 wraps the connecting plates 3 on both sides of the guardrail rod 2, and the appearance is very regular and beautiful.

[0028] On this basis, a push lock 5 detachably connected to the bottom frame 200 can also be provided at the bottom end of the frame 1 on the side opposite to the snap-fit ​​mechanism. The structure here can refer to the structure shown in the applicant's prior application CN108825099 A; wherein, the snap-fit ​​mechanism can also be replaced by push locks 5 located at both ends of the frame 1 on both sides, further achieving a quick release effect, but correspondingly reducing the anti-theft effect.

[0029] In this embodiment, the guardrail 2 is a metal tube with a circular cross section. Specifically, solid stainless steel with a diameter of 6 mm is used. This ensures the structural strength of the guardrail 2 while also minimizing obstruction to the window, thereby ensuring maximum daylighting through the window.

[0030] In this embodiment, the guardrail 2 is divided into longitudinal bars 2a and transverse bars 2b. The longitudinal bars 2a connect three of the transverse bars 2b to form an opening 21 for the window handle to rotate. The opening 21 is sized to ensure the window handle can rotate. The length of one of the transverse bars 2b is shortened so that the middle of the longitudinal bar 2a is connected to the end of the transverse bar 2b, and the upper and lower ends of the longitudinal bar 2a are connected to the remaining two transverse bars 2b.

[0031] In this embodiment, the connection between the guardrail 2 and the connecting plate 3 and the guardrail 2 is achieved by spot welding.

[0032] Example 2

[0033] refer to Figure 5 、 Figure 6 Compared with the first embodiment, the guardrail 2 is a metal square tube structure with a rectangular cross section and inwardly indented corners 22 on all sides. This embodiment provides a guardrail 2 structure with greater structural strength. The cross section of the guardrail 2 has a long side 2c and a short side 2d. The middle of the short sides 2d on both sides of the guardrail 2 has an inwardly indented recess 23. The recess 23 can increase the structural strength of a single guardrail 2. When welding guardrails 2, the connection position is made by cutting off the two short sides 2d on one side so that the long side 2c on that side contacts the other guardrail 2 at the connection position. The welding point is in the shape of an arc line, the welding position is large, and the structural stability is strong.

[0034] Structurally, the connections between the guardrails 2 are all located on the short sides 2d, while the long sides 2c face the windows. The structural strength is increased compared to the first embodiment, but the shielding surface is also increased.

[0035] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
