Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a door and window sub-frame. Background Art

[0002] In the prior art, doors and windows are an indispensable part of a living room. So far, doors and windows have gone through four eras, namely wooden, steel, aluminum alloy and plastic-steel doors and windows. When installing doors and windows, we will use a sub-frame. Through the opening and closing of the building door and window sub-frame, the ventilation in the room is facilitated.

[0003] The existing sub-frame is generally as Figure 5 shown. By setting up a sub-frame 11, two sets of installation frames 12 equipped with glass are slidably connected inside the sub-frame 11. Generally, when the glass needs to be replaced or cleaned, the installation frame 12 is lifted upward, and then the installation frame 12 is taken out, and then the glass is replaced or cleaned. The above disassembly method is time-consuming and laborious, increasing the labor intensity of users. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a door and window sub-frame.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A door and window sub-frame includes a sub-frame body and two side frames. Glass is arranged inside the side frames. A sliding groove for placing the side frames is opened inside the sub-frame body. A partition frame for separating two groups of side frames is fixedly connected inside the sub-frame body. Empty grooves are opened on one side of the sub-frame body and the partition frame. A limiting mechanism is fixedly connected inside the empty grooves. The limiting mechanism includes a connecting plate fixedly connected inside the empty grooves. A connecting groove is opened on one side of the connecting plate. A limiting plate is hinged inside the connecting groove. Placing grooves are opened on both sides of the limiting plate. A clamping plate is slidably connected inside the placing grooves. Clamping grooves are opened on both inner walls of the placing grooves. The two groups of clamping grooves correspond to the two groups of clamping plates respectively. A spring is fixedly connected inside the placing grooves. One side of the spring is fixedly connected to the clamping plate.

[0007] Preferably, two groups of positioning grooves are opened on one side of the connecting plate. The two groups of positioning grooves are respectively communicated with the two groups of clamping grooves. A pull rod is fixedly connected to one side of the clamping plate. The pull rod is adapted to the positioning grooves. Relief grooves are opened on both sides of the limiting plate.

[0008] Preferably, positioning plates are fixedly connected to both inner walls of the placing grooves.

[0009] The beneficial effects of the present utility model are as follows: A door and window sub-frame provided by the present utility model can be controlled to open and close by pushing and pulling the frame during user use, which is convenient for ventilation. When it is necessary to disassemble the frame with glass, the pull rod can be pulled to drive the clamping plate to move, so that the clamping plate disengages from the clamping groove, and then the limiting plate can be rotated so that it no longer limits the upper part of the frame, and then the frame can be taken out, which is convenient for the user to disassemble. After the glass is replaced or cleaned, the frame can be placed in the corresponding sliding groove, and then the limiting plate is rotated. When the clamping groove is completely communicated with the placement groove, due to the establishment of the spring, the clamping block will snap into the inside of the clamping groove, thereby limiting the limiting plate and not affecting the normal use of the frame.

[0017] Such as Figure 1 - Figure 4As shown in the figure, a door and window sub-frame provided by the utility model includes a sub-frame body 1 and two side frames 2. Glass is arranged inside the side frames 2. A sliding groove 3 for placing the side frames 2 is opened inside the sub-frame body 1. A partition frame 4 for separating two groups of side frames 2 is fixedly connected inside the sub-frame body 1. Empty slots 5 are opened on one side of the sub-frame body 1 and the partition frame 4. A limiting mechanism 6 is fixedly connected inside the empty slots 5. The limiting mechanism 6 includes a connecting plate 61 fixedly connected inside the empty slot 5. A connecting groove 62 is opened on one side of the connecting plate 61. A limiting plate 63 is hinged inside the connecting groove 62. Placing grooves 64 are opened on both sides of the limiting plate 63. A clamping plate 65 is slidably connected inside the placing grooves 64. Clamping grooves 66 are opened on the inner walls on both sides of the placing grooves 64. The two groups of clamping grooves 66 correspond to the two groups of clamping plates 65 respectively. A spring 67 is fixedly connected inside the placing groove 64. One side of the spring 67 is fixedly connected to the clamping plate 65. Two positioning grooves 69 are opened on one side of the connecting plate 61. The two groups of positioning grooves 69 are respectively communicated with the two groups of clamping grooves 66. A pull rod 610 is fixedly connected to one side of the clamping plate 65. The pull rod 610 is adapted to the positioning groove 69. Relief grooves 611 are opened on both sides of the limiting plate 63; when it is necessary to disassemble the side frame 2 equipped with glass, the pull rod 610 can be pulled to drive the clamping plate 65 to move, so that the clamping plate 65 is disengaged from the clamping groove 66, and then the limiting plate 63 can be rotated so that it no longer limits the upper part of the side frame 2, and then the side frame 2 can be taken out, which is convenient for the user to disassemble.
