Description

Technical Field

[0001] The present application relates to the technical field of doors and windows, and specifically to a plastic-steel door and window corner strength reinforcement structure. Background Art

[0002] Plastic steel doors and windows are made of polyvinyl chloride resin as the main raw material, with a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., extruded into profiles, and then made into door and window frames and sashes by cutting, welding or screwing.

[0003] The existing patent (publication number: CN219197135U) has announced a plastic steel door and window corner strength reinforcement structure, including a first frame and a second frame, the lower end of the first frame is fitted with the right side of the second frame, the first frame and the second frame are both provided with a groove, the inside of the groove is fixedly connected with an L-shaped support plate, the diagonal part of the L-shaped support plate is rotatably connected with a threaded rod, the rod wall of the threaded rod is slidably connected with a fixed block, both sides of the fixed block are rotatably connected with a rotating plate, the back side of the rotating plate is rotatably connected with the two inner walls of the L-shaped support plate, the rod wall of the threaded rod is threadedly connected with a knob, and the knob is rotatably connected with the fixed block. In this scheme, by rotating the knob, the fixed block drives the rotating plate to rotate, and then the fixed block has a certain pulling force on the rotating plate, so that the first frame and the second frame are more tightly connected, and compared with directly fixing through a plate, the rotating plate has a certain prestress, and thus has better stability.

[0004] The above structure is achieved by turning the knob, which moves to the upper right on the rod wall of the threaded rod, and the knob drives the fixed block to move to the upper right, and the movement of the fixed block drives the two rotating plates to rotate. When the rotating plate rotates, the pulling force of the rotating plate on the L-shaped supporting plate becomes larger. By twisting the knob with force, the pulling force of the rotating plate on the L-shaped supporting plate is increased, thereby improving the tightness of the connection between the first frame and the second frame. However, after turning the knob, the second frame and the first frame are both subjected to an inclined pulling force, which causes uneven pressure on the contact surface of the first frame and the second frame. The pressure on the top of the contact surface of the two is greater than the pressure on the bottom, which easily causes a gap to appear at the bottom. At the same time, grooves are provided on the first frame and the second frame, which easily reduces the strength of the connection. When subjected to external impact force, deformation is easily caused, resulting in reduced sealing of doors and windows. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a plastic-steel door and window corner strength reinforcement structure, which has the advantages of good reinforcement effect, etc., and solves the problem that the second frame and the first frame are both subjected to inclined pulling force, which causes uneven pressure on the contact surface between the first frame and the second frame. The pressure on the top of the contact surface of the two is greater than the pressure on the bottom, which easily causes gaps to appear at the bottom. At the same time, grooves are provided on the first frame and the second frame, which easily reduces the strength of the connection. When subjected to external impact force, deformation is likely to occur, resulting in reduced sealing of doors and windows.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a plastic steel door and window corner strength reinforcement structure, comprising a first connecting frame and a second connecting frame, wherein the first connecting frame and the second connecting frame are provided with a same traction frame inside, wherein the traction frame is L-shaped, and threaded rods are rotatably connected between the left and right inner side walls and between the upper and lower inner walls of the traction frame;

At the same time, through the close contact between the set supporting connecting frame and the first connecting frame and the second connecting frame, the wall thickness of the connection between the first connecting frame and the second connecting frame can be increased, thereby improving the overall strength and avoiding the occurrence of dents when impacted.

[0009] Furthermore, the inner walls of the first connecting frame and the second connecting frame are fixedly connected with four guide bars, and each of the supporting connecting frames is slidably connected with adjacent guide bars.

[0010] According to the above solution, the slidable connection between the support connection frame and the guide bar can facilitate the assembly of the support connection frame with the first connection frame and the second connection frame.

[0011] Furthermore, a group of connection holes are formed on the outer surfaces of the first connection frame and the second connection frame, and each group of connection holes penetrates the supporting connection frame.

[0012] Through the above solution, by setting the connection holes, the purpose of fixing the supporting connection frame and the first connection frame or the second connection frame can be achieved.

[0013] Furthermore, a power shaft is rotatably connected to the right end angle of the upper surface of the traction frame, and a first bevel gear is fixedly connected to the bottom end of the power shaft. The ends of the two threaded rods close to the power shaft are fixedly connected to second bevel gears, and the two second bevel gears are meshed with the first bevel gear.

[0014] Through the above solution and the provision of the first bevel gear, the purpose of rotating the two threaded rods can be achieved.

[0015] Furthermore, a power disk is fixedly connected to the top end of the power shaft, and a hexagonal groove is formed on the upper surface of the power disk.

[0016] Through the above solution, by setting the hexagonal groove, it is convenient for the user to use an external handheld drill to rotate the power shaft.

[0017] Furthermore, an operation groove is formed at one end of the first connecting frame and the second connecting frame that are close to each other.

[0018] Through the above solution and the setting of the operating slot, it is convenient for the user to insert the output end of the external handheld drill into the hexagonal slot.

[0019] Furthermore, the two traction plates are both slidably connected to the traction frame.

[0020] Through the above solution, the traction plate is slidably connected to the traction frame, so that the traction plate can move stably inside the traction frame.

[0021] Furthermore, the inner walls of the first connecting frame and the second connecting frame are in close contact with the outer surface of the supporting connecting frame adjacent thereto.

[0022] Through the above solution, by supporting the connecting frame in close contact with the inner walls of the first connecting frame and the second connecting frame, the purpose of supporting the first connecting frame and the second connecting frame can be achieved, and the strength of the first connecting frame and the second connecting frame can be improved.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The plastic steel door and window corner strength reinforcement structure drives the first bevel gear to rotate through the power shaft, which can drive the two second bevel gears to rotate, and achieves the purpose of the two threaded rods synchronously driving the supporting connecting frame and the second connecting frame to move along the horizontal direction of the first connecting frame and the second connecting frame, so that the contact surface of the first connecting frame and the second connecting frame can be evenly stressed, and the contact tightness of the first connecting frame and the second connecting frame can be improved. At the same time, through the close contact between the set supporting connecting frame and the first connecting frame and the second connecting frame, the wall thickness of the connection between the first connecting frame and the second connecting frame can be increased, thereby improving the overall strength and avoiding the occurrence of dents when impacted.
