Description
Technical Field
[0001] The utility model belongs to the technical field of window frame corner connection, and particularly relates to a corner connection structure for a broken bridge aluminum alloy window sash. Background Technique
[0002] The corner connection of the window sash generally adopts the corner code connection method, the injection glue corner code connection method, the screw splicing method, and the corner welding method for the splicing of the window frame. The corner connection is a relatively weak part in the door and window frame. Through an effective corner connection process, the corner strength of the door and window can be significantly enhanced, making it more stable and durable, and maintaining the stability of the basic frame of the door and window.
[0003] In the common connection process of the window frame corner, it is generally fixed by glue or screws. During the splicing process, the connection is realized through screws or glue. However, in the actual use process, screw fixation requires additional holes to be drilled in the window frame, which damages the integrity of the window frame, affects the airtightness of the window frame, and the glue or screw connection affects the overall appearance of the window frame. Therefore, we provide a corner connection structure for a broken bridge aluminum alloy window sash to solve the above technical problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a corner connection structure for a broken bridge aluminum alloy window sash, which solves the problems in the above background technique through the specific structural design of the window frame assembly, the corner connection assembly, and the limit assembly.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a corner connection structure for a broken bridge aluminum alloy window sash, including two adjacent window frame assemblies, a corner connection assembly, and a limit assembly. The two window frame assemblies are connected and fixed through the corner connection assembly. The window frame assembly includes a fixedly arranged butt joint fixing block; the corner connection assembly includes limit clamping connecting rods symmetrically and rotatably connected to both sides, and the limit clamping connecting rods are clamped and matched with the butt joint fixing blocks of the corresponding window frame assemblies. By sliding the limit clamping connecting rods along the corresponding butt joint fixing blocks respectively and then engaging after separation, the connection between the two window frame assemblies is completed; the limit assembly is clamped and matched with the corresponding window frame assembly, and the limit assembly includes a rotatable limit butt joint block, and the limit butt joint block rotates and is clamped and matched with the corresponding window frame assembly to realize the fixation between the window frame assembly and the corner connection assembly.
[0007] The present utility model is further configured such that the window frame assembly further includes a window frame body, a docking groove is formed inside the window frame body, and a vertical limiting plate is fixedly connected between opposite inner side walls of the docking groove; the docking fixing blocks are respectively symmetrically fixedly connected to opposite inner side walls of the docking groove, the docking fixing blocks are trapezoidal structures, and a first docking port communicating with the docking groove is formed on one side surface of the window frame body.
[0008] The present utility model is further configured such that the corner connection assembly further includes a hollow right-angle connection column, the hollow right-angle connection column is a structure formed by splicing two hollow docking columns, and the hollow docking columns are respectively slidably disposed inside corresponding docking grooves; the limiting and engaging connecting rods are symmetrically fixedly connected to one side surface of the hollow right-angle connection column through ear plates, an arc-shaped spring is fixedly connected between the two limiting and engaging connecting rods, second docking ports are formed on adjacent side surfaces of the hollow right-angle connection column, and the second docking ports correspond to the corresponding first docking ports.
[0009] The present utility model is further configured such that the limiting assembly includes a horizontal support plate, a through hole is formed on the surface of the horizontal support plate, a sliding support plate is rotatably connected inside the through hole, and a support tube is fixedly connected to the upper surface of the horizontal support plate; a sliding limiting column is slidably disposed inside the support tube, the sliding support plate is slidably disposed on the circumferential surface of the sliding limiting column, a limiting block is fixedly connected to the circumferential surface of the sliding limiting column, a return spring is fixedly connected between the limiting block and the sliding support plate, and the return spring is sleeved outside the sliding limiting column; a rotating handle is fixedly connected to the upper end of the sliding limiting column, and a limiting docking block is fixedly connected to the circumferential surface of the sliding limiting column.
[0010] The present utility model has the following beneficial effects:
[0011] 1. By providing the window frame assembly and the corner connection assembly, both ends of the hollow right-angle connection column are respectively inserted into the corresponding docking grooves. When one end of the limiting and engaging connecting rod contacts the inclined surface of the docking fixing block, the limiting and engaging connecting rods rotate synchronously and approach each other, and the arc-shaped spring is compressed. Until it leaves the docking fixing block, the arc-shaped spring elastically returns. The triangular limiting block on the limiting and engaging connecting rod is used to achieve clamping and fixing with the docking fixing block, thereby realizing the connection of the two window frame bodies, avoiding the use of screws or adhesives, and affecting the appearance of the window frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Specific Embodiment 1
[0025] Please refer to Figures 1-6 , the present utility model is a corner connection structure for a broken bridge aluminum alloy window sash, which includes two adjacent window frame components 1, a corner connection component 2, and a limit component 3. The two window frame components 1 are connected and fixed through the corner connection component 2, and the splicing between the two window frame components 1 is realized by using the corner connection component 2. The window frame component 1 includes a fixedly arranged butt joint fixing block 101; the corner connection component 2 includes limit clamping connecting rods 201 symmetrically and rotatably connected to both side surfaces. The limit clamping connecting rod 201 has a structure in which a triangular limit block is arranged at one end of the connecting rod. The limit clamping connecting rod 201 is clamped and matched with the butt joint fixing block 101 of the corresponding window frame component 1. By sliding the limit clamping connecting rod 201 along the corresponding butt joint fixing block 101 respectively, and then engaging after separation, the connection between the two window frame components 1 is completed; the limit component 3 is clamped and matched with the corresponding window frame component 1. The limit component 3 includes a rotatable limit butt joint block 301. The limit butt joint block 301 rotates and is clamped and matched with the corresponding window frame component 1 to realize the fixation between the window frame component 1 and the corner connection component 2, and the window frame component 1 and the corner connection component 2 are further fixed by using the limit butt joint block 301.
[0026] The operation process of this embodiment is as follows: When splicing the two window frame components 1, both ends of the corner connection component 2 are respectively inserted into the corresponding window frame components 1. During this process, the limit clamping connecting rod 201 moves horizontally inside the window frame component 1. When one end of the limit clamping connecting rod 201 contacts the butt joint fixing block 101, as the limit clamping connecting rod 201 continues to move horizontally, the limit clamping connecting rod 201 slides along the surface of the butt joint fixing block 101 and rotates under extrusion. When the limit clamping connecting rod 201 passes through the two butt joint fixing blocks 101, the two limit clamping connecting rods 201 return to their original states and are clamped and fixed with the butt joint fixing blocks 101, thereby completing the splicing between the two window frame components 1; to increase the connection stability, by rotating the limit butt joint block 301, it is clamped and matched with the window frame component 1, and the connection between the window frame component 1 and the corner connection component 2 is further strengthened. Specific Embodiment 2
[0028] Please refer to Figures 1-6, on the basis of Specific Embodiment 1, specifically, the window frame assembly 1 further includes a window frame body 102. A docking groove 103 is formed inside the window frame body 102. A vertical limiting plate 104 is fixedly connected between the opposite inner side walls of the docking groove 103; docking fixing blocks 101 are symmetrically and fixedly connected to the opposite inner side walls of the docking groove 103 respectively. The docking fixing block 101 has a trapezoidal structure, and the inclined surface of the docking fixing block 101 is away from the vertical limiting plate 104. A first docking port 105 communicating with the docking groove 103 is formed on one side surface of the window frame body 102.
[0029] Further, the corner connection assembly 2 further includes a hollow right-angle connection column 202. The hollow right-angle connection column 202 is a structure formed by splicing two hollow docking columns. The hollow docking columns are respectively slidably arranged inside the corresponding docking grooves 103; limiting and engaging connecting rods 201 are symmetrically and fixedly connected to one side surface of the hollow right-angle connection column 202 through ear plates. An arc spring 203 is fixedly connected between the two limiting and engaging connecting rods 201. When the limiting and engaging connecting rods 201 rotate synchronously, the arc spring 203 is compressed. After docking, under the elastic recovery action of the arc spring 203, the limiting and engaging connecting rods 201 return to their original state and engage. Second docking ports 204 are formed on the adjacent two side surfaces of the hollow right-angle connection column 202, and the second docking ports 204 correspond to the corresponding first docking ports 105.
[0030] The operation process of this embodiment is as follows: When docking two window frame assemblies 1, insert the two ends of the hollow right-angle connection column 202 into the corresponding docking grooves 103 respectively. During this process, the hollow right-angle connection column 202 slides inside the docking groove 103. When one end of the limiting and engaging connecting rod 201 contacts the inclined surface of the docking fixing block 101, the limiting and engaging connecting rod 201 is squeezed, and the two rotate synchronously and approach each other. At the same time, the arc spring 203 is compressed. The limiting and engaging connecting rod 201 continues to move until it leaves the inclined surface of the docking fixing block 101. Under the elastic recovery action of the arc spring 203, the two limiting and engaging connecting rods 201 rotate in the opposite direction and return to their original positions. One side surface of the triangular limiting block at the end of the limiting and engaging connecting rod 201 fits with the docking fixing block 101, thereby completing the clamping and fixing. At the same time, the second docking ports 204 correspond to the corresponding first docking ports 105. Specific Embodiment 3
[0032] Please refer to Figures 1-6 , on the basis of Specific Embodiment 1 and Specific Embodiment 2, specifically, the limiting assembly 3 includes a horizontal support plate 302.

[0033] Further, a sliding limit post 305 is slidably arranged inside the support tube 304. The sliding support plate 303 is slidably arranged on the circumferential side of the sliding limit post 305. The sliding limit post 305 can slide up and down along the sliding support plate 303 to drive the limit docking block 301 to move synchronously. A limit block is fixedly connected to the circumferential side of the sliding limit post 305. A return spring 306 is fixedly connected between the limit block and the sliding support plate 303. The return spring 306 is sleeved outside the sliding limit post 305. A rotating handle 307 is fixedly connected to the upper end of the sliding limit post 305. The rotating handle 307 rotates a certain angle and is pressed down, compressing the return spring 306 and driving the sliding limit post 305 to move downward. The limit docking block 301 is fixedly connected to the circumferential side of the sliding limit post 305.
[0034] The operation process of this embodiment is as follows: Place the horizontal support plate 302 directly above the window frame body 102. The limit docking block 301 is located directly above the first docking port 105. The horizontal support plate 302 approaches the window frame body 102. When the horizontal support plate 302 is in contact with one side surface of the window frame body 102, the limit docking block 301 penetrates through the first docking port 105 and the second docking port 204. Press down the rotating handle 307 in the direction of the first docking port 105. The sliding limit post 305 slides a certain distance along the sliding support plate 303. The return spring 306 is compressed. The rotating handle 307 rotates a certain angle, causing the limit docking block 301 to deviate from the first docking port 105. Release the rotating handle 307. Under the elastic recovery action of the return spring 306, the limit docking block 301 is in contact with the inner side wall of the window frame body 102, completing the snap connection and fixation, further connecting and fixing the window frame assembly 1 and the corner connection assembly 2.
