Description

Technical Field

[0001] The present invention relates to the technical field of window frame installation, and in particular to an oblique insertion type window frame fixing structure and an installation device thereof. Background Art

[0002] Currently, screws are commonly used to fix the outer frame of the window frame to the building's auxiliary frame. The conventional practice is to penetrate the top of the cavity on the indoor side and drive the screw into the auxiliary frame to form a single-point connection. However, the pull-out strength provided by a single screw fixation is limited. Under strong wind loads, stress concentration can easily lead to connection failure, posing a safety hazard of the entire window frame loosening or even blowing off. To increase strength, some solutions use double screws to penetrate the top of the indoor and outdoor cavities. Although this enhances the rigidity of the connection, it undermines the structural integrity of the top of the outdoor cavity. Since this area has a key drainage function, a water seepage path is formed after the screws penetrate, causing rainwater to penetrate the cavity, causing quality problems such as wall corrosion and insulation failure.

[0003] During the window frame installation process, screws need to be screwed in to connect the window frame and the auxiliary frame. The existing installation method usually relies on workers to directly screw in the screws with a handheld electric screwdriver. However, this installation method lacks a precise guiding mechanism. The screws are prone to tilting due to uneven force or positioning deviation during the screwing process, causing an angular deviation between the screw axis and the preset hole position, weakening the effective connection depth and wind pressure resistance. In addition, the high-speed rotating screw head is prone to slipping off the screwdriver bit, which not only reduces installation efficiency, but may also scratch the profile surface or cause personal injury.

DETAILED DESCRIPTION

[0032] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0033] like Figure 1As shown, the present invention is an oblique insertion window frame fixing structure, comprising an outer frame body 100 and an auxiliary frame 200 located below the outer frame body 100, a first cavity 101 and a second cavity 102 are respectively provided near the bottom end of the outer frame body 100, an opening is respectively provided on the side of the first cavity 101 close to the outside and the side of the second cavity 102 close to the inside of the room, and a sealing cover plate 300 is clamped and installed at the opening, an inclined fastening screw 103 is passed through the bottom of the first cavity 101 and the second cavity 102, and the tail of the fastening screw 103 is screwed into the auxiliary frame 200, and the heads of the two fastening screws 103 respectively contact the inner walls of the first cavity 101 and the second cavity 102.

[0034] It should be noted that the tails of the two fastening screws 103 are screwed into the auxiliary frame 200 to form a double-point anchor, and the heads are pressed against the inner wall of the cavity to generate a bidirectional constraint force, which significantly improves the pull-out strength and wind pressure resistance; the penetration position of the fastening screws 103 is strictly limited to the bottom of the cavity, completely avoiding the top of the first cavity 101, ensuring that the top drainage structure is complete and has no perforations, and avoiding rainwater infiltration to cause wall corrosion or insulation failure; the sealing cover plate 300 is used to facilitate the sealing of the first cavity 101 and the second cavity 102 after the fastening screws 103 are installed, which not only plays a waterproof role, but also facilitates the hidden protection of the fastening screws 103.

[0035] like Figure 1 As shown, the gap between the outer frame 100 and the auxiliary frame 200 is filled with a foaming agent layer 201, and the side walls of the sealing cover 300 near the top and bottom ends are symmetrically provided with inward-bending elastic claws 301, and the inner walls of the first cavity 101 and the second cavity 102 are provided with locking bosses 104 that are engaged with the elastic claws 301, and sealing strips that are compatible with the sealing cover 300 are installed in the first cavity 101 and the second cavity 102, and a drainage channel 105 is provided on the top of the first cavity 101.

[0036] It should be noted that the use of the foaming agent layer 201 not only facilitates filling the gaps but also improves the thermal insulation and sound insulation effects. The elastic claws 301 and the locking bosses 104 are interference fit to force the sealing cover plate 300 to be pressed against the inner wall of the cavity. The sealing strip can effectively improve the sealing effect. An independent drainage channel 105 is set on the top of the first cavity 101, which is physically isolated from the penetration area of ​​the bottom fastening screws 103, completely avoiding the risk of perforation of the fastening screws 103 to destroy the drainage function.

[0037] like Figure 2-Figure 10It is shown that an embodiment of the present invention provides an installation device for an obliquely inserted window frame fixing structure, which is used for installing an obliquely inserted window frame fixing structure, including a positioning plate 400 located in the first cavity 101 and / or the second cavity 102, and a positioning mechanism 500 for locking its position is installed on the positioning plate 400, and an inclined guide member 600 is provided through the positioning plate 400, and the guide member 600 is used to guide the installation of the fastening screw 103, and a shell 700 that can fit therewith is rotatably installed at one end of the guide member 600 close to the head of the fastening screw 103, and a tightening mechanism 800 for driving the fastening screw 103 to rotate and apply thrust to it is installed in the shell 700, and a deflection mechanism 900 is installed between the positioning plate 400 and the shell 700, and the deflection mechanism 900 is used to control the deflection of the shell 700 along the end of the guide member 600.

[0038] It should be noted that when in use, the positioning plate 400 is placed at a suitable position in the first cavity 101 or the second cavity 102, and the positioning mechanism 500 is used to lock the position of the positioning plate 400, and then the fastening screw 103 is inserted into the guide part 600, and the deflection mechanism 900 is started to deflect the shell 700 until the end of the shell 700 is in contact with the end of the guide part 600, and the position of the fastening screw 103 is adjusted so that its head drive groove is docked with the tightening mechanism 800. Starting the tightening mechanism 800 not only drives the fastening screw 103 to rotate but also always applies thrust to it, so that the fastening screw 103 is accurately screwed in along the guide part 600, so that the tail of the fastening screw 103 passes through the bottom of the cavity until it is screwed into the auxiliary frame 200, and the installation of the fastening screw 103 is completed. Subsequently, the position lock of the positioning plate 400 is canceled, its position in the cavity is adjusted, and the previous operation is repeated to install the fastening screws 103 in sequence.

[0039] like Figure 2-Figure 3 and Figure 7As shown, the positioning mechanism 500 includes a bottom shell 501, a first piston 502, a negative pressure shell 503, a second piston 504, a sliding rod 505, a bellows 506, a bump 507, a pressure plate 508 and a negative pressure pipe fitting 509. The bottom shell 501 is a top-opening structure, and the two bottom shells 501 are symmetrically installed on the side wall near the bottom end of the positioning plate 400. The bottom end of the negative pressure shell 503 extends into the bottom shell 501, and the negative pressure shell 503 slides through the bottom of the bottom shell 501. The negative pressure pipe fitting 509 is installed between the bottom shell 501 and the negative pressure shell 503. The first piston 502 is sleeved on the outside of the negative pressure shell 503, and the first piston 502 is set In the bottom shell 501, the second piston 504 is slidably arranged in the negative pressure shell 503, the sliding rod 505 is installed on the top of the second piston 504, and the sliding rod 505 slides through the top of the negative pressure shell 503 and is connected to the pressure plate 508, the bellows 506 is sleeved on the outside of the sliding rod 505, and the two ends of the bellows 506 are respectively connected to the second piston 504 and the lower surface of the top of the negative pressure shell 503, and the side wall of the negative pressure shell 503 is provided with an air inlet 5031 located below the first piston 502, and the protrusion 507 is installed on the side of the negative pressure shell 503 close to the positioning plate 400, and the side wall of the positioning plate 400 is provided with a recess for inserting the protrusion 507.

[0040] The first piston 502 is subjected to downward pressure from the air pressure, which drives the negative pressure shell 503 to always maintain a downward movement trend. The protrusion 507 is convenient for always pressing down the positioning plate 400, thereby ensuring that the positioning plate 400 can always be pressed against the bottom of the cavity. The pressure plate 508 pressed against the top of the cavity can be locked by the pressure plate 508.

[0041] like Figure 2 and Figure 4 As shown, the negative pressure pipe fitting 509 includes a U-shaped main pipe 5091, an inverted L-shaped auxiliary pipe 5092, an exhaust hose 5093 and an air intake valve 5094. The two ends of the U-shaped main pipe 5091 are respectively connected to the inner cavities of the two bottom shells 501, and the pipe mouth of the U-shaped main pipe 5091 is located below the first piston 502. One end of the inverted L-shaped auxiliary pipe 5092 is connected to the inner cavity near the top of the negative pressure shell 503, and the other end of the inverted L-shaped auxiliary pipe 5092 is connected to the U-shaped main pipe 5091. The air intake valve 5094 is installed on the U-shaped main pipe 5091.

[0042] It should be noted that the exhaust hose 5093 is connected to the external exhaust equipment to facilitate the exhaust to form a negative pressure state. When the positioning plate 400 is locked in position, the air intake valve 5094 is closed to prevent outside air from entering the U-shaped main pipe 5091. When the position lock is canceled, the air intake valve 5094 is opened to allow outside air to be adaptively replenished, thereby releasing the conflict between the positioning plate 400 and the pressure plate 508.

[0043] like Figure 5 and Figure 8 As shown, the guide member 600 includes a rectangular tube 601, an annular cavity 602 and a through groove 603. The rectangular tube 601 passes through the positioning plate 400 and is arranged at an angle. The annular cavity 602 is arranged in the rectangular tube 601. The head of the fastening screw 103 is slidingly arranged with the annular cavity 602. Two through grooves 603 are symmetrically opened on the side wall of the rectangular tube 601 near the top.

[0044] It should be noted that, in this embodiment, the inner diameter of the annular cavity 602 is equal to the outer diameter of the head of the fastening screw 103, so as to facilitate the limiting of the fastening screw 103 so that it can only slide along the length direction of the annular cavity 602. When the shell 700 is in contact with the end of the rectangular tube 601, since the fastening screw 103 is located in the annular cavity 602, the through groove 603 is used to facilitate the user to adjust the position of the internal fastening screw 103, thereby facilitating the docking of the fastening screw 103 with the tightening mechanism 800.

[0045] like Figure 4 and Figure 9 As shown, the tightening mechanism 800 includes a servo motor 801, a rotating drum 802, a screw rod 803, a rotating sliding member 804, a threaded block 805 and a magnetic bit 806. The rotating drum 802 is located in the housing 700, and the top of the rotating drum 802 is rotatably connected to the top of the housing 700. The servo motor 801 is installed at the top of the housing 700 and is used to drive the rotating drum 802 to rotate. The threaded block 805 is installed at the inner wall of the housing 700 near one end of the guide member 600. One end of the screw rod 803 extends into the rotating drum 802 through the threaded block 805 and is connected to the rotating sliding member 804. The rotating drum 802 drives the screw rod 803 to rotate synchronously through the rotating sliding member 804, and the screw rod 803 can drive the rotating sliding member 804 to move along the rotating drum 802. The magnetic bit 806 is coaxially installed at the other end of the screw rod 803.

[0046] It should be noted that in order to facilitate checking whether the driving groove of the head of the fastening screw 103 is docked with the magnetic bit 806, in this embodiment, U-shaped openings are provided on the four side walls of the housing 700 near one end of the magnetic bit 806. The magnetic bit 806 is conveniently docked with the driving groove of the head of the fastening screw 103. The servo motor 801 is started to drive the rotating drum 802 to rotate. The rotating sliding member 804 is used to facilitate the synchronous rotation of the lead screw 803 and the magnetic bit 806 when the rotating drum 802 rotates. Since the position of the threaded block 805 is limited, the lead screw 803 can move toward the fastening screw 103 when it rotates, which not only facilitates the rotation of the fastening screw 103, but also facilitates the constant application of thrust to it, so that the fastening screw 103 can be screwed in and fed stably along the guide member 600.

[0047] like Figure 4 and Figure 9 As shown, the rotating sliding member 804 includes an annular block 8041 and a limit key 8042. The annular block 8041 is coaxially connected to the end of the screw rod 803 away from the magnetic bit 806. Multiple limit keys 8042 are distributed circumferentially along the annular block 8041. The inner cylinder wall of the rotating cylinder 802 is provided with a limit groove 8021 for the limit key 8042 to slide, and the limit groove 8021 is arranged along the length direction of the rotating cylinder 802.

[0048] It should be noted that the use of the limit key 8042 and the limit slot 8021 not only enables the rotating drum 802 to drive the annular block 8041 and the screw rod 803 to rotate synchronously, but also does not affect the movement of the screw rod 803.

[0049] like Figure 2 、 Figure 5 as well as Figure 10 As shown, the deflection mechanism 900 includes a guide rail 901, an electric slider 902, a connecting rod 903, a crossbeam 904, a first reinforcing column 905 and a second reinforcing column 906. The guide rail 901 is vertically connected to the outer wall of the guide member 600, the electric slider 902 is installed on the guide rail 901, one end of the connecting rod 903 is hinged to the outer wall of the shell 700, and the other end of the connecting rod 903 is hinged to the electric slider 902, one end of the crossbeam 904 is connected to the side wall of the positioning plate 400, and the other end is connected to the bottom of the guide rail 901 away from the guide member 600, the first reinforcing column 905 is installed between the crossbeam 904 and the guide rail 901, and the second reinforcing column 906 is installed between the guide rail 901 and the guide member 600.

[0050] It should be noted that the electric slider 902 slides along the guide rail 901. This is an existing technology and will not be elaborated on here. When the electric slider 902 slides along the guide rail 901 in a direction away from the positioning plate 400, the hinged connecting rod 903 is used to conveniently drive the shell 700 to deflect along the end of the guide member 600, thereby facilitating the installation of the fastening screw 103 into the guide member 600, and utilizing the crossbeam 904, the first reinforcement column 905 and the second reinforcement column 906 to conveniently form multiple stable triangular structures, thereby effectively ensuring the stability of the guide rail 901 and forming a stable support.

[0051] like Figure 2 and Figure 3 As shown, a groove is provided on the side of the positioning plate 400 away from the guide rail 901, and a resistance block 401 is movably arranged in the groove. A screw 402 is coaxially connected to the side of the resistance block 401 close to the bottom of the groove. The screw 402 passes through the bottom of the groove and extends outward, and the screw 402 is threadedly connected to the bottom of the groove.

[0052] It should be noted that, in order to further improve the stability of the positioning plate 400 when it is locked, when the positioning plate 400 is placed into the cavity, one side of the positioning plate 400 is aligned with the locking boss 104 (eg, Figure 1 As shown), the position of the interference block 401 can be adjusted by rotating the screw 402 until the interference block 401 is tightly pressed against the side of the cavity away from the sealing cover plate 300, thereby further improving the stability of the positioning plate 400 when the position is locked.

[0053] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
