Description

Technical Field

[0001] This utility model relates to the field of doors and windows, specifically to a door and window handle installation structure. Background Technology

[0002] A door and window handle installation structure is a mechanical component used to fix door and window handles. It typically includes the handle body, connecting base, fixing screws or bolts, etc. The base is aligned with the pre-embedded holes in the door and window frame or sash, and the screws are used to firmly fix the handle to the door and window, ensuring that the handle is stable and does not wobble during opening and closing.

[0003] CN111809964B discloses a handle for preventing accidental operation of doors and windows, including a handle and an anti-accidental operation device. The anti-accidental operation device includes a base, a locking plate installed on one side of the base, a protective plate installed on the side of the locking plate away from the base, a positioning component installed on the side of the base away from the locking plate, a guide component connected to the positioning component, a fixing component installed on the positioning component, a strip-shaped square post passing through the base and the positioning component, a support on the base, and an elastic component sleeved on the guide component. Because the handle is equipped with an anti-accidental operation device, it can prevent the handle from being rotated to open the door or window due to contact or non-human action, thus improving the safety performance of the door and window and simplifying installation. Furthermore, since the anti-accidental operation device is installed inside the handle, it can reduce the movement gap of the hardware under positioning. This integrated door handle structure requires rotating the handle 45° before tightening the screws between the handle and the panel with a screwdriver to connect it, which is a complicated connection method. At the same time, the screwdriver can easily scratch the surface of the panel during installation. Therefore, this technology still has some room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a door and window handle installation structure to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a door and window handle installation structure, including a panel, one end of which is linked to a handle, characterized in that: a rotating member is provided through the center of the panel, the rotating member is rotatably connected to the panel, one end of the rotating member is provided with a reset structure for resetting after rotation, and the end of the rotating member away from the reset structure passes through the panel and is provided with a linkage member, the linkage member being detachably connected to the handle.

[0006] Using the above technical solution, the rotating part is rotatably connected to the panel, and the linkage part is detachably connected to the handle. During installation, it is only necessary to fix the handle to the linkage part and connect the other end of the rotating part to the reset structure. When the handle is rotated, it can normally link the reset structure, ensuring that the handle can reset after the door and window are closed. This avoids the need to rotate the door handle when the handle is directly connected to the panel, and also avoids the screwdriver directly contacting the panel surface and scratching the panel surface.

[0007] The aforementioned door and window handle installation structure can be further configured such that: the linkage component has a first mounting cavity at the end facing the rotating component, the end of the rotating component is placed in the first mounting cavity, and both the end of the rotating component and the linkage component have a plurality of first fixing holes, and the first fixing holes are provided with first fixing bolts.

[0008] By adopting the above technical solution, the first mounting cavity opened at the end of the linkage component facing the rotating component ensures the coaxial cooperation between the two; the end of the rotating component and the corresponding first fixing hole on the linkage component are firmly connected by the first fixing bolt, thereby fixing the rotating component and the linkage component and preventing loosening or displacement during operation.

[0009] The aforementioned door and window handle installation structure can be further configured such that: a second mounting cavity is provided at the end of the handle facing the linkage component, the linkage component is placed in the second mounting cavity, and both the handle and the linkage component are provided with a plurality of second fixing holes, and a second fixing bolt is provided in the second fixing hole.

[0010] Using the above technical solution, the second mounting cavity provided at the end of the handle facing the linkage provides installation space for the linkage, enabling the linkage to be embedded in the handle and ensuring stable linkage between the two. The handle and the corresponding second fixing hole on the linkage are firmly connected by the second fixing bolt, realizing a stable connection between the two. During installation, the handle only needs to be connected to the linkage through the second fixing hole, avoiding the need to turn the door handle when the traditional handle is directly connected to the panel.

[0011] The aforementioned door and window handle installation structure can be further configured as follows: the rotating part has a plurality of positioning posts on its surface, the first installation cavity has an insertion groove for the positioning posts to be inserted into, the rotating part has a fixing groove on its outer periphery, and the installation cavity has a fixing block that is inserted into the fixing groove.

[0012] By adopting the above technical solution, the positioning post on the surface of the rotating part and the insertion into the first mounting cavity facilitate the positioning connection between the rotating part and the linkage part. The insertion of the fixing groove and the fixing block strengthens the limiting between the two, ensuring that the lock will not sag or fall during long-term use.

[0013] The aforementioned door and window handle installation structure can be further configured as follows: a wear-resistant structure is provided between the panel and the linkage component to prevent wear. The wear-resistant structure includes a spacer block arranged around the rotating component of the panel. A first mounting groove for installing a first wear component is formed between the spacer block and the surface of the panel. A second mounting groove for installing a second wear component is provided on the outer periphery of the first mounting cavity of the linkage component. Both the first mounting groove and the second mounting groove are provided with a plurality of snap-fit ​​blocks. Both the first wear component and the second wear component are provided with snap-fit ​​grooves that snap-fit ​​with the snap-fit ​​blocks. The first wear component and the second wear component abut against each other.

[0014] By adopting the above technical solution, the anti-wear structure is set between the panel and the linkage, which effectively avoids direct contact between the two and prevents gaps from forming due to wear during use. The spacer block set around the rotating part of the panel forms a first mounting groove with the panel surface, and the second mounting groove on the outer periphery of the linkage is used to install the second wear part. The two are fixed by the snap-fit ​​block and snap-fit ​​groove. The first wear part and the second wear part replace the abutment, which avoids gaps from forming after long-term friction between the panel and the linkage during use.

[0015] The aforementioned door and window handle mounting structure can be further configured as follows: the reset structure includes a torsion spring seat fixedly disposed on one side of the rotating component, a third mounting cavity is provided on the side of the panel away from the linkage component, the torsion spring seat is placed in the third mounting cavity, a reset torsion spring is sleeved on the torsion spring seat, and at least one first abutting member abutting against the reset torsion spring is provided in the third mounting cavity.

[0016] Using the above technical solution, the torsion spring seat fixed on one side of the rotating component is placed in the third mounting cavity on the side of the panel away from the linkage component. The elastic potential energy of the torsion spring is used to realize the reset of the rotating component. The first abutting component in the third mounting cavity abuts against the torsion spring, providing support for the torsion spring.

[0017] The aforementioned door and window handle installation structure can be further configured as follows: the first abutting member is symmetrically arranged at the upper and lower ends of the torsion spring seat, the two ends of the reset torsion spring abut against the first abutting member at the upper and lower ends respectively, and the third mounting cavity is located on both sides of the torsion spring seat and is also provided with a second abutting member that limits the maximum rotation angle of the torsion spring.

[0018] Using the above technical solution, the first abutment member with symmetrical upper and lower parts provides bidirectional abutment for the reset torsion spring, enabling the handle to rotate bidirectionally. The setting of the second abutment member in the third mounting cavity limits the maximum rotation angle of the torsion spring, preventing damage to the reset torsion spring caused by excessive torsion, which could lead to reset failure.

[0019] The aforementioned door and window handle installation structure can be further configured such that: a fourth mounting cavity for installing a handle cover plate is provided on one side of the handle, and mounting posts for embedding magnets are provided on one side of the handle cover plate and inside the fourth mounting cavity, and the handle cover plate is magnetically connected to the handle.

[0020] Using the above technical solution, mounting posts are provided on one side of the handle cover and inside the fourth mounting cavity for embedding magnets. The magnets are connected to the mounting posts with an interference fit. The handle cover is made of metal, which realizes the magnetic connection between the cover and the handle, enabling the handle cover to be embedded in the fourth mounting cavity.

[0021] The aforementioned door and window handle installation structure can be further configured such that both the first wear part and the second wear part are stainless steel or stainless steel.

[0022] By adopting the above technical solution, stainless steel or stainless steel materials have high hardness and wear resistance, which can effectively reduce friction loss and extend the service life of components when the panel and linkage move relative to each other. At the same time, their excellent corrosion resistance can resist the erosion of wear parts by harsh environments such as moisture, acid and alkali, and avoid jamming or failure caused by rust.

[0023] The aforementioned door and window handle installation structure can be further configured such that the first abutting member and the second abutting member cause the torsion spring to rotate at a maximum angle of 45°.

[0024] Using the above technical solution, 45° is the standard rotation angle of handles on the market. The 45° rotation angle limit ensures that the torsion spring will not fail or be damaged due to excessive torsion during the reset process, while avoiding the aggravation of component wear caused by excessive rotation angle.

[0025] The beneficial effects of this utility model are as follows: the rotating part is rotatably connected to the panel, and the linkage part is detachably connected to the handle. During installation, it is only necessary to fix the handle to the linkage part and connect the other end of the rotating part to the reset structure. During installation, the handle only needs to be connected to the linkage part through the second fixing hole, which avoids the need to turn the door handle when the traditional handle is directly connected to the panel.

[0033] like Figure 1-5The present invention provides the following technical solution: a door and window handle installation structure, including a panel 1, a handle 2 linked to one end of the panel 1, a rotating member 3 passing through the center of the panel 1, the rotating member 3 being rotatably connected to the panel 1, a reset structure 4 for resetting after rotation at one end of the rotating member 3, and a linkage member 5 passing through the panel 1 at the other end of the rotating member 3 away from the reset structure 4, the linkage member 5 being detachably connected to the handle 2. During installation, only the handle 2 needs to be fixedly connected to the linkage member 5, and the other end of the rotating member is connected to the reset structure 4. The handle 2 rotates... The linkage reset structure 4 can be normally linked to ensure that the handle 2 can be reset after the door and window are closed. This avoids the need to turn the door handle 2 when the handle 2 is directly connected to the panel 1, and also avoids the screwdriver directly contacting the surface of the panel 1 and scratching the surface of the panel 1. The linkage 5 has a first mounting cavity 6 at the end facing the rotating part 3. The end of the rotating part 3 is placed in the first mounting cavity 6. Both the end of the rotating part 3 and the linkage 5 have several first fixing holes 7. The first fixing holes 7 are provided with first fixing bolts 8. The first mounting cavity 6 at the end of the linkage 5 facing the rotating part 3 ensures the coaxial cooperation between the two.The end of the rotating component 3 is securely connected to the corresponding first fixing hole 7 on the linkage component 5 by the first fixing bolt 8, thus fixing the rotating component 3 and the linkage component 5 and preventing loosening or displacement during operation. A second mounting cavity 9 is provided at the end of the handle 2 facing the linkage component 5, and the linkage component 5 is placed inside the second mounting cavity 9. Both the handle 2 and the linkage component 5 are provided with several second fixing holes 10, and second fixing bolts 11 are installed in the second fixing holes 10. The second mounting cavity 9 at the end of the handle 2 facing the linkage component 5 provides installation space for the linkage component 5, allowing the linkage component 5 to be embedded in the handle 2, ensuring stable linkage between the two. The second fixing hole 10 on the linkage 5 is firmly connected by the second fixing bolt 11, achieving a stable connection between the two. During installation, the handle 2 only needs to be connected to the linkage 5 through the second fixing hole 10, avoiding the need to rotate the door handle 2 when directly connected to the panel 1 in the traditional way. Several positioning posts 12 are provided on the surface of the rotating part, and the first mounting cavity 6 is provided with insertion slots 13 for the positioning posts 12 to be inserted. A fixing slot 14 is provided on the outer periphery of the rotating part, and a fixing block 15 is provided in the mounting cavity to be inserted into the fixing slot 14. A wear-resistant structure is also provided between the panel 1 and the linkage 5 to prevent wear. The positioning posts 12 on the surface of the rotating part and the second fixing bolt 11 are connected to the linkage 5 through the second fixing hole 10. The insertion within the mounting cavity 6 facilitates the positioning connection between the rotating component and the linkage component 5. The insertion of the fixing groove 14 and the fixing block 15 strengthens the limiting between them, preventing the lock from sagging or dropping during prolonged use. The anti-wear structure is located between the panel 1 and the linkage component 5, effectively preventing direct contact between the two and avoiding gaps caused by wear during use. The anti-wear structure includes a spacer block 16 surrounding the rotating component on the panel 1, forming a first mounting groove 18 between the spacer block 16 and the surface of the panel 1 for the installation of the first wear component 17. The linkage component 5 is located on the outer periphery of the first mounting cavity 6 and has a second wear component 19 for installation. The two mounting slots 20, the first mounting slot 18 and the second mounting slot 20, are each provided with several snap-fit ​​blocks 21. The first wear part 17 and the second wear part 19 are each provided with snap-fit ​​grooves 22 that snap into the snap-fit ​​blocks 21. The first wear part 17 and the second wear part 19 abut against each other. The spacer block 16 surrounding the rotating part of the panel 1 forms the first mounting slot 18 with the surface of the panel 1. The second mounting slot 20 on the outer periphery of the linkage part 5 is used to install the second wear part 19. The two are fixed by snap-fit ​​blocks 21 and snap-fit ​​grooves 22. The first wear part 17 and the second wear part 19 abut against each other, avoiding direct friction between the panel 1 and the linkage part 5 during use and preventing gaps from being generated.

[0034] like Figure 1-5The present invention provides the following technical solution: a door and window handle mounting structure, wherein the reset structure 4 includes a torsion spring seat 23 fixedly disposed on one side of the rotating component, a third mounting cavity 24 is provided on the side of the panel 1 away from the linkage component 5, the torsion spring seat 23 is placed in the third mounting cavity 24, a reset torsion spring is sleeved on the torsion spring seat 23, and at least one first abutting member 25 is provided in the third mounting cavity 24 to abut against the reset torsion spring. The torsion spring seat 23 fixed on one side of the rotating component is placed in the third mounting cavity 24 on the side of the panel 1 away from the linkage component 5, and the reset of the rotating component 3 is achieved by utilizing the elastic potential energy of the torsion spring. A first abutment 25 abuts against the torsion spring, providing support for it. The first abutment is symmetrically positioned at the upper and lower ends of the torsion spring seat 23. The two ends of the reset torsion spring abut against the first abutment at each end. The third mounting cavity 24, located on both sides of the torsion spring seat 23, also has second abutment 26 that limits the maximum rotation angle of the torsion spring. The symmetrical first abutment provides bidirectional contact for the reset torsion spring, enabling the handle 2 to rotate bidirectionally. The second abutment 26 within the third mounting cavity 24 limits the maximum rotation angle of the torsion spring, preventing damage to the reset torsion spring due to excessive torsion and subsequent reset failure. The handle 2 is located on one side. A fourth mounting cavity 27 is provided for mounting the handle cover 29. Mounting posts 28 for embedding magnets are provided on one side of the handle cover 29 and inside the fourth mounting cavity 27. The handle cover 29 is magnetically connected to the handle 2. The magnets are interference-fitted with the mounting posts 28. The handle cover 29 is made of metal, enabling the magnetic connection between the cover and the handle 2, allowing the handle cover 29 to be embedded in the fourth mounting cavity 27. The first wear part 17 and the second wear part 19 are both stainless steel or stainless iron. Steel material has high hardness and wear resistance, which can effectively reduce friction loss and extend the service life of the components when the panel 1 and the linkage 5 move relative to each other. At the same time, its excellent corrosion resistance can resist the erosion of wear parts by harsh environments such as moisture, acid and alkali, and avoid jamming or failure due to rust. The first abutment and the second abutment 26 cause the torsion spring to rotate at a maximum angle of 45°. 45° is the standard rotation angle of the handle 2 on the market. The 45° rotation angle limit ensures that the torsion spring will not fail or be damaged due to excessive torsion during the reset process, and at the same time avoids the accelerated wear of the components due to excessive rotation angle.

[0035] The beneficial effects of this utility model are as follows: the rotating part 3 is rotatably connected to the panel 1, and the linkage part 5 is detachably connected to the handle 2. During installation, it is only necessary to fix the handle 2 to the linkage part 5 and connect the other end of the rotating part to the reset structure 4. During installation, the handle 2 only needs to be connected to the linkage part 5 through the second fixing hole 10, which avoids the need to rotate the door handle 2 when the traditional handle 2 is directly connected to the panel 1.
