Description

Technical Field

[0001] The utility model relates to the field of door and window hardware, in particular to an aluminum profile frame used for double-layer glass. Background Art

[0002] In recent years, the stable, continuous and rapid development of my country's national economy and high-tech has promoted the rapid development of aluminum smelting and aluminum profile processing in my country. The output and consumption of the entire aluminum profile industry have grown rapidly. The production process is low-carbon and environmentally friendly, which is in line with the national energy conservation and emission reduction and lightweight development mission of the aluminum profile industry. This makes aluminum profiles occupy an indispensable position in the construction industry. Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Due to their light weight, high strength and oxidation resistance, aluminum profiles are currently widely used in building decoration, doors and windows and other materials, especially in office spaces, where more and more glass partitions and glass doors and windows are used, and their frame structures are usually made of aluminum profiles.

[0003] After searching, the Chinese patent "A frame profile for double-glazed doors and windows" has the authorization announcement number "CN218971012 U". This patented technology fixes the double-glazed glass by covering the outer frame profile with a positioning cover plate. It is easy to install and disassemble, and is also convenient for repairing damaged glass.

[0004] Although the patented technology solves the problem that the current aluminum profile design of glass door and window connection structure is complex, uses a lot of materials, and is high in cost, especially for double-layer glass doors and windows. Once one layer of glass is broken, the entire glass door and window needs to be replaced, and the frame and the glass are bonded with glue, which makes assembly and disassembly inconvenient. However, the existing molar structure has high requirements for occlusal accuracy, and the molars will wear out after long-term use. The patented technology opens the molars on the surface of the fixed cover plate and the outer shell profile. Once the molars are worn, the entire fixed cover plate and profile need to be replaced, and the maintenance cost is high. Therefore, an aluminum profile frame for double-layer glass is proposed to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide an aluminum profile frame for double-layer glass in order to solve the above-mentioned problem, which improves the existing molar structure with high occlusal precision requirements and the molars will wear out after long-term use. The patented technology opens the molars on the surface of the fixed cover plate and the shell profile. Once the molars are worn, the entire fixed cover plate and the profile need to be replaced, which leads to high maintenance costs.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an aluminum profile frame for double-layer glass, including an aluminum profile outer frame; a locking assembly, wherein the locking assembly includes a clamping block embedded in the aluminum profile outer frame, a torsion rod is arranged in the clamping block, a gear is fixedly connected to the bottom end of the torsion rod, a limiting block is slidably connected in the clamping block, a rack is fixedly connected to one side of the limiting block, and the rack and the gear are meshed with each other.

[0007] Preferably, the torsion rod is rotatably connected in the block via a bearing, the number of the limit blocks is two, and they are axially symmetrically distributed, the number of the racks is two, and they are axially symmetrically distributed relative to the gear, when the limit block needs to be retracted, the gear will drive the rack to move, and the two racks are symmetrically distributed relative to the gear, and will not interfere with each other when the two racks move, and the two racks have the same length, and when the rack connected to the limit block on one side contacts the limit block on the other side, the storage of the limit block can be completed.

[0008] Preferably, the four corners of the surface of the aluminum profile outer frame are bent into an arc shape, and two glass placement grooves are opened in the aluminum profile outer frame. The length of the opened glass placement grooves is relatively long to accommodate glass of different thicknesses. When the glass thickness is narrow, the thickness of the anti-slip rubber pad can be appropriately increased to fill the empty part of the glass placement groove.

[0009] Preferably, a fixed cover plate is provided on the top of the aluminum profile outer frame, and the fixed cover plate is located below the limiting block, and the top of the fixed cover plate is consistent in height with the bottom of the limiting block, so that the limiting block can fix the fixed cover plate without loosening.

[0010] Preferably, an anti-skid rubber pad is provided in the glass placement groove, and rubber anti-skid pads are provided on both sides of the fixed cover plate surface. The rubber anti-skid pads on both sides of the fixed cover plate surface are located in the glass placement groove, and are respectively located on both sides of the glass with independent anti-skid rubber pads. The anti-skid rubber pad can fix and prevent the glass from slipping, and the material of the anti-skid rubber pad is relatively soft and will not damage the glass.

[0011] Preferably, two rectangular grooves are opened in the fixed cover plate, and the length of the rectangular grooves is consistent with the length of the card block. When the fixed cover plate needs to be inserted, the limit block is received into the card block, and the fixed cover plate can pass through the card block through the opened rectangular groove. When the fixed cover plate is installed, the limit block is unfolded. At this time, the length of the limit block is longer than the rectangular groove, so the fixed cover plate can be limited.

[0012] Preferably, a slider is fixedly connected to the bottom of the limit block, a slide groove is provided in the clamping block, and the slider is slidably connected in the slide groove. When the limit block is moved, the slider at the bottom of the limit block will slide in the slide groove, thereby limiting the limit block, which can prevent the limit block from shifting during movement, causing the gear and rack to collide and cause damage to the gear.

[0013] Preferably, a receiving groove is provided in the card block, and the card block is slidably connected in the receiving groove. When the fixed cover plate needs to be installed, the limit block is moved into the receiving groove by the gear driving the rack, so that the fixed cover plate can be placed on the top of the aluminum profile frame through the card block, and the width of the receiving groove is consistent with the width of the limit block, which can play a role in limiting the limit block together with the slider and the slide groove.

[0014] The beneficial effects of the utility model are:

[0015] When it is necessary to install the fixed cover plate, the rack is moved by torsion rod and gear. When the rack connected to the limit block on one side contacts the limit block on the other side, the storage of the limit block can be completed. At this time, the rectangular groove opened in the fixed cover plate is passed through the limit block and fits on the top of the aluminum profile frame. After that, the limit block is unfolded by the gear and rack. The unfolded limit block will limit the fixed cover plate to complete the installation of the fixed cover plate. There is no need to use groove teeth to fix the fixed cover plate to prevent the groove teeth from being worn and the entire fixed cover plate and profile need to be replaced, which leads to high maintenance costs.

[0016] By setting the slider and slide groove, when the limit block is moved, the slider at the bottom of the limit block will slide in the slide groove, thereby limiting the limit block, which can prevent the limit block from offsetting during movement and causing collision between the gear and the rack, thereby damaging the gear. The length of the slide groove is shorter than the length of the block. When the gear and the rack drive the limit block to expand, it can limit the slider and prevent the limit block from exceeding the stroke. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4 As shown, an aluminum profile frame for double-layer glass includes an aluminum profile outer frame 1; a locking assembly 2, the locking assembly 2 includes a clamping block 21 embedded in the aluminum profile outer frame 1, a torsion rod 22 is arranged in the clamping block 21, a gear 23 is fixedly connected to the bottom end of the torsion rod 22, a limiting block 24 is slidably connected in the clamping block 21, a rack 25 is fixedly connected to one side of the limiting block 24, and the rack 25 and the gear 23 are meshed with each other.

[0024] like Figure 3 and Figure 4 As shown, the torsion rod 22 is rotatably connected in the clamping block 21 through a bearing, the number of the limit blocks 24 is two, and they are axially symmetrically distributed, the number of the racks 25 is two, and they are symmetrically distributed relative to the gear 23. When the glass needs to be installed, the fixed cover plate 4 and the anti-skid rubber pad 5 are placed in the glass placement groove 3, and then the glass is inserted into the glass placement groove 3, so that the glass can be fixed. The existing frame and the glass are bonded by glass glue, which is inconvenient to assemble and disassemble. By fixing the glass with the anti-skid rubber pad 5, it is not necessary to use glass glue to fix the glass, and assembly and disassembly are more convenient.

[0025] like Figure 1 and Figure 2 As shown, the four corners of the surface of the aluminum profile outer frame 1 are bent into an arc shape, two glass placement grooves 3 are opened in the aluminum profile outer frame 1, a fixed cover plate 4 is arranged on the top of the aluminum profile outer frame 1, and the fixed cover plate 4 is located below the limit block 24. An anti-slip rubber pad 5 is arranged in the glass placement groove 3, and two rectangular grooves 6 are opened in the fixed cover plate 4. The length of the rectangular groove 6 is consistent with the length of the block 21. The frame of the existing glass window is relatively sharp, and most of the glass windows in the office are in an open state, which is prone to collision and may cause harm to the human body. By setting the arc-shaped aluminum profile outer frame 1, the damage caused by the collision can be reduced, which is safer.

[0026] like Figure 3 and Figure 4 As shown, a slider 7 is fixedly connected to the bottom of the limit block 24, a slide groove 8 is provided in the block 21, the slider 7 is slidably connected in the slide groove 8, a receiving groove 9 is provided in the block 21, the block 21 is slidably connected in the receiving groove 9, the length of the slide groove 8 is shorter than the length of the block 21, when the gear 23 and the rack 25 drive the limit block 24 to expand, the slider 7 can be limited to prevent the limit block 24 from exceeding the stroke.

[0027] When the utility model is in use, when it is necessary to install the fixed cover plate 4, the rack 25 is driven to move by the torsion rod 22 and the gear 23. When the rack 25 connected to the limit block 24 on one side contacts the limit block 24 on the other side, the storage of the limit block 24 can be completed. At this time, the rectangular groove 6 opened in the fixed cover plate 4 passes through the limit block 24 and fits on the top of the aluminum profile outer frame 1. After that, the limit block 24 is unfolded by the gear 23 and the rack 25. The unfolded limit block 24 will limit the fixed cover plate 4 to complete the installation of the fixed cover plate 4. There is no need to use grooves to fix the fixed cover plate 4 to prevent the grooves from being worn and the entire fixed cover plate 4 and the profile need to be replaced, which leads to high maintenance costs.

[0028] When it is necessary to install the glass, the glass is placed in the glass placement groove 3 , and the glass placed in the glass placement groove 3 can be fixed by the installed fixing cover plate 4 through cooperation with the anti-skid rubber pad 5 .

[0029] It should be noted that the gear 23, rack 25 and anti-skid rubber pad 5 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs and will not be described in detail here.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
