[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 in 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] Reference Figure 1 - Figure 2 , Figure 4, the utility model provides an embodiment: a plastic-steel window frame plug-in connection structure, including a connecting window frame 1, the connecting window frame 1 is a prior art, which is a connecting part for splicing plastic-steel window frame profiles, a through hole 1 2 is opened at the right end of the upper surface of the connecting window frame 1, and the through hole 1 2 is convenient for workers to use a hexagonal wrench to rotate the threaded rod 41, and a through hole 2 5 is opened on the right surface of the connecting window frame 1, and the through hole 2 5 is adapted to the clamping rod 42 to ensure the stability of the fixation, and the inner wall of the through hole 2 5 is provided with a connecting component 3, and the inner wall of the right side of the top of the connecting component 3 is provided with a fixing component 4, and the connecting component 3 includes an L-shaped connecting frame 31, and the L-shaped connecting frame 31 is L-shaped, which is convenient for splicing multiple groups of connecting window frames 1, and the L-shaped connecting frame 31 slides on the inner wall of the connecting window frame 1, and a rotating rod 39 is rotatably connected to the lower surface of the L-shaped connecting frame 31, and a circular plate 34 is fixedly connected to the upper surface of the rotating rod 39, and the circular plate 34 is rotatably connected to the inner wall of the bottom end of the L-shaped connecting frame 31.

[0032] Reference Figure 1 - Figure 2 , Figure 4 The fixing assembly 4 includes a threaded rod 41. The threaded rod 41 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. At the same time, it has the characteristic of axial self-locking to ensure the stability of the structural connection. The threaded rod 41 penetrates and is rotatably connected to the right end of the upper surface of the L-shaped connecting frame 31. The inner wall of the top end of the threaded rod 41 is hexagonal in shape, which is convenient for workers to use a hexagonal wrench to control its rotation. The outer wall of the threaded rod 41 is threadedly connected with a slide plate 44, and the slide plate 44 slides on the inner wall of the right side of the top end of the L-shaped connecting frame 31.

[0033] Reference Figure 2 - Figure 4 The connecting component 3 also includes a top plate 33, which is slidably connected to the right surface of the L-shaped connecting frame 31. A rectangular plate 32 is fixedly connected to the right surface of the top plate 33. The rectangular plate 32 contacts the inner wall of the connecting window frame 1. The right end of the rectangular plate 32 is made of rubber material, which is set to be rubber material to make the rectangular plate 32 and the connecting window frame 1 more stable. When the window frame 1 is plugged in, the unfolded size of the rectangular plate 32 can be made larger than the inner wall size of the connecting window frame 1 to ensure the stability of the connection. A through groove 36 is opened on the upper surface of the circular plate 34, and the number of through grooves 36 is multiple groups. The through grooves 36 have a certain inclination to ensure that when the circular plate 34 is rotated, the sliding rod 35 will drive the top plate 33 to move along the inclination of the through groove 36. The inner wall of the through groove 36 is slidably connected with a sliding rod 35, and the upper surface of the sliding rod 35 is fixedly connected to the lower surface of the left end of the top plate 33.

[0034] Reference Figure 3 - Figure 4The connecting assembly 3 also includes a limit rod 37, which is slidably connected to the lower surface of the L-shaped connecting frame 31 near the right side of the rotating rod 39. The lower surface of the circular plate 34 is provided with grooves in multiple groups. The top of the limit rod 37 contacts the inner wall of the groove. The upper surface of the limit rod 37 is set as an inclined surface to ensure that the rectangular plate 32 does not need to pull the limit rod 37 when unfolding, thereby improving work efficiency. The outer wall of the limit rod 37 is sleeved with a spring 38. The spring 38 always pulls the limit rod 37 upward through its own elasticity to ensure the stability of the limit rod 37. One end of the spring 38 is fixedly connected to the lower surface of the L-shaped connecting frame 31, and the other end of the spring 38 is fixedly connected to the upper surface of the limit rod 37.

[0035] Reference Figure 2 , Figure 4 The fixed component 4 also includes a moving plate 43, which is slidably connected to the inner wall on the right side of the top of the L-shaped connecting frame 31. A clamping rod 42 is fixedly connected to the right surface of the moving plate 43. The right end of the clamping rod 42 contacts the inner wall of the through hole 25. The bottom end of the slide plate 44 is slidably connected to the inner wall of the moving plate 43. When the slide plate 44 moves along the axial direction of the threaded rod 41, it will drive multiple groups of moving plates 43 to move up and down or horizontally.

[0036] Working principle: When in use, when the connecting component 3 needs to be adjusted according to the inner wall size of the frame of the plastic-steel window, just turn the rotating rod 39, and the rotating rod 39 will drive the circular plate 34 to rotate. At this time, the sliding rod 35 will move on the inner wall of the through groove 36, and the sliding rod 35 will drive the top plate 33 to move along the slope of the through groove 36, and the top plate 33 will push the rectangular plate 32 to move, so that the connecting component 3 can fix the frames of plastic-steel windows of different sizes. During the adjustment process, it is necessary to make sure that the unfolded size of the rectangular plate 32 is slightly larger than the size of the inner wall of the connecting window frame 1 to ensure that the rubber material on the right end of the rectangular plate 32 can play a role.

[0037] At the same time, during the adjustment process, if the process is to expand multiple groups of rectangular plates 32, the circular plate 34 will push the limit rod 37 downward along the inclined surface to disengage from the inner wall of the groove, and the limit rod 37 will stretch the spring 38, and the limit rod 37 will overlap with another group of grooves. At this time, the spring 38 will drive the limit rod 37 to move in the opposite direction through its own structure, so that the limit rod 37 is inserted into the inner wall of another group of grooves, and this is repeated to ensure the convenience of adjustment. If the rectangular plate 32 is to shrink back, it is necessary to pull the limit rod 37 and reverse the circular plate 34. The subsequent structural coordination method is the same as above.

[0038] After the splicing is completed, a hexagonal wrench can be used to pass through the through hole 1 2 and extend into the inner wall of the top end of the threaded rod 41 to control the threaded rod 41 to rotate. At this time, the slide plate 44 threadedly connected to the outer wall of the threaded rod 41 will move linearly in the opposite direction along the axis of the threaded rod 41. At this time, the multiple groups of movable plates 43 will also move under their drive. The movable plate 43 will drive the clamping rod 42 to move and insert it into the inner wall of the through hole 2 5. In this way, the final fixation can be completed, which is quick and convenient, and improves work efficiency.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
