Description

Technical Field

[0001] This invention relates to the field of door and window fittings technology, and in particular to door and window fitting installation structures, door and window fittings and pulleys. Background Technology

[0002] Existing quick-release structures for door and window fittings typically use screws and lugs. When the screw is turned, the lugs rotate together due to the thread between the screw and the lugs, causing the end of the lugs to screw into the fitting mounting groove of the profile. As the screw continues to turn, due to the thread between the screw and the lugs and the limiting effect of the side wall of the fitting mounting groove of the door and window profile on the lugs, the lugs move upward, causing the upper end face of the lugs to approach the top wall of the fitting mounting groove of the door and window profile, until the lugs abut against the top wall of the fitting mounting groove.

[0003] Because the aforementioned quick disassembly and assembly method uses a rotating fastener, there is a risk that the fastener may be accidentally driven to rotate and loosen during the use of door and window accessories. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a door and window fitting installation structure, door and window fittings and pulleys, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this invention is:

[0006] A door and window fitting installation structure, comprising a control side and a fixing side.

[0007] The installation structure includes:

[0008] Top wall;

[0009] The limiting sidewall is fixed relative to the top wall and is provided with a limiting hole;

[0010] Tighten the screw; the screw is rotatably connected to the top wall.

[0011] The lower moving part is threaded to the tail end of the tightening screw, and the end of the lower moving part protrudes through the limiting hole.

[0012] A deformation plate is disposed between the top wall and the lower moving part. The deformation plate includes an extension plate, a top plate, and a connecting plate. The top plate is fixed relative to the top wall, and the extension plate and the top plate are connected by the connecting plate. The extension plate abuts against the lower moving part.

[0013] Both the lower moving part and the deformation plate are located on the control side; when the distance between the lower moving part and the top wall changes, the extension plate extends out of the fixed side or retracts into the control side.

[0014] With the above technical solution, when the screw is tightened and rotated, the lower moving part is limited and cannot rotate, only moving vertically. This causes the distance between the lower moving part and the top wall to increase or decrease. Since the deformation plate is positioned between the lower moving part and the top wall, and the protruding piece abuts against the lower moving part, changes in the space between them cause the deformation plate to deform. Specifically, when the lower moving part approaches the top wall, the protruding piece extends to the fixed side; when the lower moving part moves away from the top wall, the protruding piece retracts to the control side. As the lower moving part approaches the top wall, the protruding piece also gradually approaches the upper wall of the door and window fitting mounting groove until it abuts against the upper wall, completing the installation of the door and window fittings.

[0015] The limiting sidewall limits the lower moving part, preventing it from rotating and thus avoiding the situation where the lower moving part is accidentally driven to rotate, which could lead to loosening.

[0016] As a further improvement to the above technical solution, the deformation plate is provided with a central axis surface, and the number of connecting plates and protruding plates is set to at least two, with the at least two connecting plates and protruding plates arranged symmetrically about the central axis surface.

[0017] As a further improvement to the above technical solution, the end of the connecting piece away from the top wall is bent away from the central axis surface.

[0018] With the above technical solution, when the space where the deformation plate is located becomes smaller, the deformation plate deforms, which can ensure that the extension plate moves away from the central axis surface, thereby ensuring that the extension plate can extend to the fixed side.

[0019] As a further improvement to the above technical solution, the connecting piece is inclined, with the end of the connecting piece away from the top wall being further away from the central axis than the end of the connecting piece closer to the top wall.

[0020] Through the above technical solution, the deformable sheet of this embodiment can be adapted to pulleys with a larger width. By adapting the deformable sheet of this embodiment to pulleys with a larger width, the steps required for forming the deformable sheet can be reduced, thereby improving factory production efficiency.

[0021] As a further improvement to the above technical solution, at least two deformation plates are provided, with the protruding pieces of the two deformation plates respectively located on both sides of the mounting structure.

[0022] As a further improvement to the above technical solution, the end face of the lower moving part near the top wall protrudes with an inclined guide portion. The inclined guide portion is located on the side of the protruding piece away from the fixed side, and the inclined guide portion gradually tilts away from the top wall towards the fixed side.

[0023] By using the above technical solution, and by setting an inclined guide, when the distance between the protruding piece and the top piece in the vertical direction is shortened, the deformable piece deforms, which can further ensure that the protruding piece moves away from the central axis surface, thereby ensuring that the protruding piece can extend to the fixed side.

[0024] As a further improvement to the above technical solution, the top wall is provided with a nail head groove, and the head of the tightening screw is completely located in the nail head groove.

[0025] With the above technical solution, the head of the tightening screw is completely set in the screw head groove, and the head of the tightening screw does not exceed the screw head groove, so that the end face of the head of the tightening screw is flush with the upper end face of the top wall, thus preventing the head of the tightening screw from protruding.

[0026] A door and window fitting includes an outer frame and several mounting structures as described above, wherein the top wall and the limiting side wall are different walls of the outer frame.

[0027] The above technical solution and installation structure can prevent door and window fittings from becoming loose.

[0028] As a further improvement to the above technical solution, a pulley includes a pulley frame and a plurality of mounting structures as described above, wherein the plurality of mounting structures are arranged along the length direction of the pulley frame, and the top wall and the limiting side wall are different wall surfaces of the pulley frame.

[0029] The above technical solution and installation structure can prevent the pulley from becoming loose.

[0030] As a further improvement to the above technical solution, a size compensation frame is also included. The size compensation frame is sleeved on the pulley frame and the size compensation frame is detachably connected to the pulley frame. The size compensation frame is provided with a through hole corresponding to the limiting hole.

[0031] Through the above technical solution, the size compensation frame allows the pulley to be adapted to the installation grooves of door and window hardware accessories of different widths.

[0032] The beneficial effect of this invention is that it prevents door and window fittings from becoming loose.

[0033] This invention relates to the field of door and window fittings technology. Attached Figure Description

Detailed Implementation

[0040] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0041] Example 1:

[0042] Reference Figures 1 to 4 A pulley includes a pulley frame 110, an inner frame 120, and a wheel body 130. The inner frame 120 is installed inside the pulley frame 110 and is movably connected to the pulley frame 110 (see figure for specific structure; the basic structure of the pulley is a conventional setting in this field, and the structure of the pulley will not be described in detail here). The wheel body 130 is rotatably connected to the inner frame 120.

[0043] The pulley frame 110 is provided with a mounting structure, and the number of mounting structures is set to two, which are arranged in the front-to-back direction.

[0044] The mounting structure has a fixed side and a control side. The mounting structure includes a top wall 210, two limiting side walls 220, a tightening screw 230, a lower moving part 240, and a deformation plate 250.

[0045] The top wall 210 is set as the upper wall surface of the pulley frame 110, and the two limiting side walls 220 are respectively set as the left and right side walls of the pulley frame 110. The top wall 210 and the limiting side walls 220 are fixedly connected. Specifically, the pulley frame 110 is integrally formed by stamping sheet metal.

[0046] The top wall 210 has a screw head groove, and the side wall of the screw head groove has a conical structure. The tightening screw 230 is a countersunk screw, and the tightening screw 230 adopts a conventional Phillips head screw head. The head of the tightening screw 230 is conical. The tightening screw 230 passes through the top wall 210 and is rotatably connected to the top wall 210. The head of the tightening screw 230 is completely set in the screw head groove, and the head of the tightening screw 230 does not exceed the screw head groove, so that the end face of the head of the tightening screw 230 is flush with the upper end face of the top wall 210, avoiding the head of the tightening screw 230 from protruding.

[0047] The side formed by the limiting sidewall 220 and the top wall 210 is the control side, and the outer side is the fixed side.

[0048] The limiting sidewall 220 is provided with a limiting hole 221, which is a square hole structure formed by stamping. The limiting hole 221 penetrates the limiting sidewall 220 in the left and right direction.

[0049] The deformation plate 250 has a central axial surface, and the central axis of the tightening screw 230 is located on the central axial surface. The deformation plate 250 is configured as an elastic member, and includes a top plate 251, a connecting plate 252, and an extension plate 253. The top plate 251 abuts against the top wall 210 of the pulley frame 110, and the two ends of the connecting plate 252 are fixedly connected to the top plate 251 and the extension plate 253, respectively.

[0050] In this embodiment, two connecting pieces 252 are symmetrically arranged about the central axis. Two extending pieces 253 are also symmetrically arranged about the central axis. The end of the connecting piece 252 away from the top wall 210 bends away from the central axis. When the vertical distance between the extending piece 253 and the top piece 251 decreases, the space occupied by the deformable piece 250 becomes smaller, causing the deformable piece 250 to deform. This ensures that the extending piece 253 moves away from the central axis, thus ensuring that the extending piece 253 can extend to the fixed side. To reduce the space occupied by the connecting piece 252 and the top piece 251 in the left-right direction, the connecting piece 252 gradually tilts away from the top piece 251 towards the fixed side, and bends away from the central axis at the end away from the top wall 210. That is, the connecting piece 252 is V-shaped, and the V-shaped opening of the connecting piece 252 faces the fixed side. This better accommodates pulleys with smaller widths.

[0051] The lower moving member 240 is configured as a rigid sheet structure with a certain thickness to prevent excessive deformation and thus provide greater rigidity. The lower moving member 240 is located on the control side and abuts against the protruding piece 253 to support it. A threaded hole is provided in the middle of the lower moving member 240, which is threaded to the tail end of the tightening screw 230. Both the front and rear walls of the lower moving member 240 abut against the side walls of the limiting hole 221, thus limiting the lower moving member 240. When the tightening screw 230 rotates, because the lower moving member 240 is limited, it cannot rotate but can only move vertically, causing the distance between the lower moving member 240 and the top wall 210 to increase or decrease.

[0052] The lower moving part 240 has an inclined guide part 241 protruding from the middle of the top wall 210. The inclined guide part 241 is located on the side of the protruding piece 253 away from the fixed side, and the wall surface of the inclined guide part 241 gradually tilts away from the top wall 210 towards the fixed side. By setting the inclined guide part 241, when the distance between the protruding piece 253 and the top piece 251 in the vertical direction is shortened, the deformable piece 250 deforms, which can further ensure that the protruding piece 253 moves away from the central axis surface, thereby ensuring that the protruding piece 253 can extend to the fixed side.

[0053] The lower moving part 240 can support the protruding piece 253, guide the protruding piece 253, and compress the deformable piece 250 in the vertical direction.

[0054] Furthermore, the pulley in this embodiment may optionally be equipped with a size compensation frame 140. The size compensation frame 140 has various sizes to accommodate door and window hardware mounting slots of different widths. The size compensation frame 140 is fitted onto the pulley frame 110, and the size compensation frame 140 and the pulley frame 110 are detachably connected. The side wall of the size compensation frame 140 has a through hole corresponding to the limiting hole 221.

[0055] Example 2:

[0056] Unlike Embodiment 1, the connecting piece 252 in this embodiment is inclined. The end of the connecting piece 252 away from the top wall 210 is further away from the central axis surface than the end of the connecting piece 252 closer to the top wall 210. The deformable piece 250 in this embodiment can be adapted to a pulley with a larger width. By adapting the deformable piece 250 to a pulley with a larger width, the steps required for forming the deformable piece 250 can be reduced, thereby improving factory production efficiency.

[0057] Example 3:

[0058] Unlike Embodiments 1 and 2, the installation structure in this embodiment includes two deformable pieces 250 arranged in a front-to-back direction. The top piece 251 of the deformable piece 250 is fixedly connected to the top wall 210 of the pulley frame 110 by welding. Each deformable piece 250 includes only one protruding piece 253, one top piece 251, and one connecting piece 252. The protruding pieces 253 and connecting pieces 252 of the two deformable pieces 250 located in the same installation structure are respectively disposed on the left and right sides of the pulley. When the screw 230 is turned, the protruding pieces 253 of the two deformable pieces 250 extend from the left and right sides of the pulley respectively, and cooperate with the hardware mounting groove of the door and window profile, so that the installation structure fixes the left and right sides of the pulley to the door and window profile respectively.

[0059] In other embodiments, the installation structures of Embodiments 1, 2, and 3 described above can be applied to door and window fittings, such as door and window lock points, door and window lock seats, and door and window upper pulleys, to achieve quick installation and removal of door and window fittings and prevent loosening. The door and window fittings have an outer frame and several installation structures (the installation structures are selected based on the specific door and window fittings, and at least one installation structure can be used). The top wall 210 is the upper wall surface of the outer frame, and the limiting side walls 220 are the left and right side walls of the outer frame.

[0060] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
