Description

Technical Field

[0001] The present invention relates to the field of building doors and windows, and particularly to a butt-jointed building exterior window. Background Art

[0002] A building exterior window is equivalent to a window on the building exterior wall, facing the outdoors on one side and the indoors on the other side. During the construction of the building exterior wall, the installation of the exterior window is a crucial task, which is not only related to the aesthetics of the building but also to the safety performance of the building.

[0003] The stability of the window door of the existing building exterior window is weak after installation. When the window door is blown by the wind, it is easy to shake, and the shaking window door collides with the outer frame body, posing a safety risk. Summary of the Invention

[0012] A pulley assembly is hinged to the movable rod. The pulley assembly rotates around a vertical axis. The pulley assembly is provided with a driving rod extending outward, and the driving rod is movably connected to the push rod. The left and right movement of the push rod drives the pulley assembly to rotate so that the pulley assembly abuts against the inner wall of the upper limit groove.

[0013] The beneficial effects of the present invention are as follows: After installing the top of the inner frame into the upper sliding groove of the outer frame, the top of the inner frame pushes the movable rod upward, the movable rod drives the sliding rod upward, and the guide rod of the sliding rod moves along the guide groove of the guide block, causing the guide rod to drive the sliding rod to move in the left-right direction. Then, the push rod moves in the left-right direction to drive the driving rod of the pulley assembly, so that the driving rod drives the pulley assembly to rotate. The rotated pulley assembly abuts against the inner wall of the upper limit groove of the inner frame, thereby restricting the freedom of the inner frame to shake in the front-back direction. When the inner frame is blown by the wind, it is not easy to shake, preventing the inner frame from colliding with the outer frame and eliminating safety risks.

Understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number.

[0043] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0044] Referring to Figures 1 to 10 , the following embodiments are made for the docking type building exterior window of the present invention:

[0045] The docking type building exterior window includes an outer frame 1, an inner frame 22, a movable rod 26, a guide block 41, a sliding rod 43, and a pulley assembly 45.

[0046] The outer frame 1 is a rectangular frame structure. The top of the outer frame 1 is provided with an upper sliding groove which penetrates in the up and down direction and extends left and right along the top of the outer frame 1.

[0047] The guide block 41 is installed at the end of the upper sliding groove. The bottom of the guide block 41 is provided with a guide groove extending upward, and the guide groove gradually inclines to the left or right from bottom to top.

[0048] The movable rod 26 is arranged in the upper sliding groove. The movable rod 26 extends in the left and right direction and can slide up and down along the upper sliding groove. The top of the inner frame 22 is inserted into the upper sliding groove. The inner frame 22 can slide left and right along the upper sliding groove. The top of the inner frame 22 abuts against the bottom of the movable rod 26. The top of the inner frame 22 is provided with an upper limit groove which penetrates the inner frame 22 in the left and right direction, and the movable rod 26 is located in the upper limit groove.

[0049] The sliding rod 43 is slidably connected to the top of the movable rod 26. The sliding rod 43 slides in the left and right direction. A guide rod is arranged at the end of the sliding rod 43. The guide rod is inserted into the guide groove and slides along the guide groove. A push rod 44 is arranged in the middle of the sliding rod 43, and the push rod 44 extends outward.

[0050] The middle part of the pulley assembly 45 is hinged to the top of the movable rod 26. The pulley assembly 45 rotates around an axis extending in the up and down direction. After rotation, both ends of the pulley assembly 45 extend out of the front and rear sides of the movable rod 26 respectively. The pulley assembly 45 is provided with a driving rod extending towards the push rod 44, and the driving rod is movably connected to the push rod 44. In this embodiment, the driving rod is provided with a connecting groove extending along the length direction of the driving rod. The push rod 44 is provided with a slider, and the slider is movably arranged in the connecting groove. The slider can slide and rotate in the connecting groove. Then, when the push rod 44 moves left and right, the slider drives the driving rod to rotate in the connecting groove.

[0051] When the inner frame 22 is installed on the outer frame 1, the top of the inner frame 22 is inserted obliquely into the upper sliding groove at the top of the outer frame 1. The movable rod 26 in the upper sliding groove is placed in the upper limit groove at the top of the inner frame 22. The inner frame 22 continues to move upward so that the bottom of the inner frame 22 can be snapped into the bottom of the outer frame 1. The upward-moving inner frame 22 pushes the movable rod 26 upward. The movable rod 26 drives the sliding rod 43 to move upward. The guide rod of the sliding rod 43 moves upward along the guide groove of the guide block 41. Since the guide groove gradually inclines leftward or rightward from bottom to top, the guide rod moves along the guide groove, causing the sliding rod 43 to slide leftward or rightward relative to the movable rod 26. The sliding rod 43 sliding in the left-right direction drives the push rod 44 to move and drive the driving rod. Then, the driving rod drives the pulley assembly 45 to rotate. Limit wheels 46 are respectively arranged at both ends of the pulley assembly 45. After rotation, the two limit wheels 46 respectively extend out of the front and rear sides of the movable rod 26. The limit wheels 46 at both ends of the pulley assembly 45 abut against the inner wall of the upper limit groove of the inner frame 22. Thus, the degree of freedom of the inner frame 22 to sway in the front-rear direction is restricted. When the inner frame 22 is blown by the wind, it is not easy to sway, preventing the inner frame 22 from colliding with the outer frame 1 and eliminating safety risks.

[0052] In some embodiments, a lifting groove is provided at the end of the upper sliding groove. The lifting groove extends in the up-down direction. A lifting block 24 is provided at the end of the movable rod 26. The lifting block 24 is slidably arranged in the lifting groove, and the lifting block slides up and down in the lifting groove.

[0053] The cooperation of the lifting block 24 and the lifting groove makes the up-down sliding of the movable rod 26 more stable, avoiding the front-rear sway of the movable rod 26 from affecting the installation of the inner frame 22.

[0054] In some embodiments, the docking type building outer window is further provided with a first elastic member 25. The first elastic member 25 is installed in the lifting groove. The elastic force of the first elastic member 25 pushes or pulls the lifting block 24 to move downward.

[0055] After the inner frame 22 is installed on the outer frame 1, the bottom of the inner frame 22 is supported by the bottom of the outer frame 1. The inner frame 22 moves downward appropriately. The first elastic member 25 pushes or pulls the lifting block 24 to move downward. The lifting block 24 drives the movable rod 26 to move downward, causing the guide rod of the sliding rod 43 to move downward. The guide rod moves downward in the guide groove and adjusts the rotation angle of the pulley assembly 45, so that the pulley assembly 45 adjusts the distance that the two limit wheels 46 extend outwards, avoiding the two limit wheels 46 from excessively squeezing the upper limit groove of the inner frame 22.

[0056] In some embodiments, through holes are provided in the side walls of the outer frame 1. The through holes communicate with the lifting grooves. Grooves are provided in the side walls of the lifting block 24. The grooves are located on the side wall of the lifting block 24 facing the through holes. The trajectory of the grooves moving up and down with the lifting block 24 passes through the through holes. The docking type building outer window further includes a clamping member 34 and a second elastic member 36. The clamping member 34 is slidably arranged in the through hole. The second elastic member 36 is installed in the lifting groove. The second elastic member 36 connects the clamping member 34 and the lifting groove. The second elastic member 36 pushes or pulls the clamping member 34 towards the lifting block 24. When the lifting block 24 moves downward to align the groove with the through hole, the elastic force of the second elastic member 36 drives the clamping member 34 to insert into the groove.

[0057] The downward reset of the lifting block 24 causes the clamping member 34 to be stuck in the groove of the lifting block 24, thereby locking the lifting block 24 and preventing the inner frame 22 from shifting after installation, thus improving the stability of the inner frame 22.

[0058] In some embodiments, pulleys 23 are provided at the top of the inner frame 22. The pulleys 23 abut against the movable rod 26.

[0059] The inner frame 22 abuts against the movable rod 26 through the pulleys 23 at the top, making the sliding of the inner frame 22 in the upper sliding groove of the outer frame 1 smoother.

[0060] In some embodiments, an annular groove is provided on the outer periphery of the pulley 23. The annular groove restricts the freedom of the movable rod 26 to move back and forth relative to the pulley 23.

[0061] Through the cooperation of the annular groove of the pulley 23 and the movable rod 26, the freedom of the inner frame 22 to sway back and forth relative to the movable rod 26 is restricted, making the inner frame 22 more firmly installed in the outer frame 1.

[0062] In some embodiments, a lower sliding groove is provided at the bottom of the outer frame 1. The docking type building outer window is further provided with a guide strip 21. The guide strip 21 is installed in the lower sliding groove. Pulleys 23 are provided at the bottom of the inner frame 22. The pulleys 23 abut against the guide strip 21. An annular groove is provided on the outer periphery of the pulley 23. The annular groove cooperates with the guide strip 21.

[0063] Through the cooperation of the annular groove of the pulley 23 at the bottom of the inner frame 22 and the guide strip 21, the freedom of the bottom of the inner frame 22 to sway back and forth relative to the guide strip 21 is restricted, thereby making the inner frame more firmly installed in the outer frame 1.

[0064] In some embodiments, a lower limit groove is provided at the bottom of the inner frame 22. The guide bar 21 is placed in the lower limit groove. The guide bar 21 is provided with mounting holes facing the side wall of the lower limit groove. The butt-jointed building exterior window is further provided with a pressing rod 51, a third elastic member 52, and a rolling body 53. The pressing rod 51 is slidably arranged in the mounting hole in the front-back direction. The third elastic member 52 is installed in the mounting hole. The third elastic member 52 connects the mounting hole and the pressing rod 51. The third elastic member 52 pulls or pushes the pressing rod 51 to extend outwards. The rolling body 53 is hinged to the outer end of the pressing rod 51. The elastic force of the third elastic member 52 moves the pressing rod 51 outwards to make the rolling body 53 abut against the inner wall of the lower limit groove of the inner frame 22.

[0065] The pressing rod 51 of the guide bar 21 drives the rolling body 53 to abut against the inner wall of the lower limit groove of the inner frame 22, restricting the degree of freedom of the bottom of the inner frame 22 to shake back and forth relative to the guide bar 21.

[0066] In some embodiments, the butt-jointed building exterior window is further provided with a lower limit strip 7. The lower limit strip 7 is arranged on the inner wall of the lower limit groove of the inner frame 22. The lower limit strip 7 extends along the lower limit groove. The lower limit strip 7 is located above the rolling body 53. The lower limit strip 7 prevents the rolling body 53 from moving upwards relative to it.

[0067] By the lower limit strip 7 preventing the rolling body 53 from moving upwards, the up-and-down shaking of the inner frame 22 relative to the guide bar 21 is reduced.

[0068] In some embodiments, the butt-jointed building exterior window is further provided with an upper limit strip 6. The upper limit strip 6 is arranged on the inner wall of the upper limit groove of the inner frame 22. The upper limit strip 6 extends along the upper limit groove. The upper limit strip 6 cooperates with the limit wheel 46 of the pulley assembly 45. The limit wheel 46 is restricted in the degree of freedom of moving up and down by the upper limit strip 6.

[0069] By the cooperation of the upper limit strip 6 and the limit wheel 46 of the pulley assembly 45, the up-and-down shaking of the inner frame 22 relative to the outer frame 1 is reduced.

[0070] Specifically, referring to Figures 1 to 10 As shown, the butt-jointed building exterior window includes an outer frame 1, a guide bar 21, an inner frame 22, a first elastic member 25, a clamping member 34, a second elastic member 36, a guide block 41, a sliding rod 43, a pulley assembly 45, a pressing rod 51, a third elastic member 52, a rolling body 53, an upper limit strip 6, and a lower limit strip 7.

[0071] Referring to Figures 1 to 5 As shown, the outer frame 1 is a rectangular frame structure. An upper sliding groove is provided at the top of the outer frame 1. The upper sliding groove penetrates in the up-and-down direction and extends left and right along the top of the outer frame 1.

[0072] The guiding block 41 is installed at the end of the upper sliding groove. The bottom of the guiding block 41 is provided with a guiding groove extending upward, and the guiding groove gradually inclines to the left or right from bottom to top.

[0073] The movable rod 26 is arranged in the upper sliding groove. The movable rod 26 extends in the left-right direction. The end of the upper sliding groove is provided with a lifting groove extending in the up-down direction. The end of the movable rod 26 is provided with a lifting block 24. The lifting block 24 is slidably arranged in the lifting groove. The lifting block slides up and down in the lifting groove, and the movable rod 26 can slide up and down along the upper sliding groove.

[0074] The side wall of the outer frame 1 is provided with a through hole, and the through hole communicates with the lifting groove. The side wall of the lifting block 24 is provided with a groove, and the groove is located on the side wall of the lifting block 24 facing the through hole. The trajectory of the groove moving up and down with the lifting block 24 passes through the through hole. The docking type building outer window further includes a clamping member 34 and a second elastic member 36. The clamping member 34 is slidably arranged in the through hole. The second elastic member 36 is installed in the lifting groove. The second elastic member 36 connects the clamping member 34 and the lifting groove. The second elastic member 36 pushes or pulls the clamping member 34 to move towards the lifting block 24. When the lifting block 24 moves downward to make the groove face the through hole directly, the elastic force of the second elastic member 36 drives the clamping member 34 to insert into the groove.

[0075] Refer to Figure 3 and Figure 4 As shown, the linkage rod 31 and the moving dial rod 32 are connected in sequence from top to bottom. The linkage rod 31 and the moving dial rod 32 are arranged in the lifting groove. The linkage rod 31 is slidably connected to the inner wall of the lifting groove. The linkage rod 31 is located on the upward movement trajectory of the lifting block 24. After the lifting block 24 moves upward, it drives the linkage rod 31 to move upward, and further makes the moving dial rod 32 move upward.

[0076] A fixing ring 35 is sleeved outside the clamping member 34. One end of the second elastic member 36 abuts against one side of the fixing ring 35 facing the through hole, and the other end abuts against the through hole. After the moving dial rod 32 moves downward, it abuts against one side of the fixing ring 35 facing the lifting groove. The moving dial rod 32 pushes the fixing ring 35 and the clamping member 34 to move outward from the through hole against the elastic force of the second elastic member 36, avoiding the clamping member 34 from hindering the movement of the lifting block 24, so as to facilitate the inner frame 22 to push the lifting block 24 upward when installing the inner frame 22.

[0077] A set of linkage rod 31 and moving dial rod 32 are respectively arranged in the lifting grooves at the left and right ends of the upper sliding groove, and the two sets of linkage rod 31 and moving dial rod 32 are connected by a connecting rod 33 to realize the linkage of the two sets of linkage rod 31 and moving dial rod 32.
