Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a polyurethane cast two-color profile. Background Technology
[0002] Doors and windows are classified as enclosure components or partition components depending on their location, and have different design requirements, including functions such as heat insulation, sound insulation, waterproofing, and fireproofing. New requirements emphasize energy conservation; in cold regions, heat loss through gaps in doors and windows accounts for approximately 25% of total heating consumption. Therefore, the airtightness of doors and windows is a crucial aspect of energy-efficient design.
[0003] Window and door profiles play a crucial role in windows and doors. They are the basic elements that make up the window and door frames, supporting and fixing various parts of the windows and doors, and have important functions such as structural support, sealing and sound insulation, and aesthetics. However, due to the special shape of the surface of existing window and door profiles, a lot of dust often accumulates in the installation grooves after long-term use. Due to their shape, cleaning is also difficult. Generally, brushes and other tools are used for cleaning, but the joints of the profiles are cleaning dead corners, where some dust often remains, making cleaning difficult and not easy to clean thoroughly. In view of this, we propose a polyurethane cast two-color profile. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a polyurethane cast two-color profile that can solve the problem of difficult and thorough cleaning after long-term use of the profile.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane casting two-color profile, including a frame, the frame being composed of four profiles spliced together, a storage groove being formed on the front surface of the lower profile, a through groove extending into the storage groove being formed on the upper surface of the lower profile, a baffle being slidably connected to the inner wall of the storage groove, a protrusion being fixedly connected to the inner wall of the storage groove, a sliding groove being formed on the side surface of the protrusion away from the storage groove, a limiting protrusion being fixedly connected to the side surface of the baffle near the protrusion, the limiting protrusion being slidably connected to the sliding groove, an L-shaped plate being fixedly connected to the rear surface of the baffle, a spring being fixedly connected to the rear surface of the L-shaped plate, the rear end of the spring being fixedly connected to the rear inner wall of the storage groove, and a second protrusion being fixedly connected to the side surface of the L-shaped plate near the protrusion.
[0006] Preferably, a cleaning plate is fixedly connected to the front surface of the L-shaped plate, and the front surface of the cleaning plate is set to be inclined.
[0007] Preferably, a corner bracket is provided at the junction of the two profiles, the corner bracket is hollow, and an mounting plate is fixedly connected to the inner wall of the corner bracket.
[0008] Preferably, a limiting rod is fixedly connected to the lower surface of the mounting plate, and a first push plate is slidably connected to the inner wall of the corner bracket, the first push plate being slidably sleeved on the outer surface of the limiting rod.
[0009] Preferably, a second push plate is slidably sleeved on the outer surface of the mounting plate, and a limiting groove is formed on the lower surface of the second push plate, with the left and right sides of the limiting groove extending out from the left and right sides of the second push plate, respectively.
[0010] Preferably, the first push plate is movably connected to the limiting groove, and the upper and right surfaces of the corner code are respectively provided with second through grooves extending into the interior of the corner code.
[0011] Preferably, a fixing plate is slidably connected to the inner wall of the second through groove.
[0012] Preferably, the two fixing plates have fixing protrusions fixedly connected to the side surface away from the inside of the corner bracket.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The polyurethane cast two-color profile can be moved by pulling the baffle. When the baffle is pulled, the L-shaped plate will move synchronously. At the same time, when the baffle moves, the movement trajectory is limited by the cooperation of the limiting protrusion and the sliding groove. When the L-shaped plate moves, the spring will be stretched synchronously and the dirt inside the collection groove will be pushed out. The user can collect the dirt by placing a trash can or similar storage item below the outlet of the collection groove. The cooperation of the second protrusion and the protrusion prevents the L-shaped plate from being completely pulled out, which would make it difficult for the user to reset. With the above structure, not only can the dirt be collected by the collection groove, but the dirt can also be removed by the L-shaped plate. This effectively avoids the problem of the profile joint being difficult to clean and improves the efficiency and quality of the user when cleaning the groove on the upper surface of the profile.
[0015] (2) When splicing the polyurethane cast two-color profile, the corner bracket is placed at the junction of the two profiles. After aligning the profiles, holes are drilled on the profiles respectively. Then, two flat-head screws are screwed into the inside of the corner bracket. After the two flat-head screws enter, they contact the first push plate and the second push plate respectively. As the flat-head screws go deeper, they will push the first push plate and the second push plate to move. When the first push plate moves, it is limited by the limiting rod to ensure that the first push plate remains horizontal when it moves. After the first push plate moves, the fixing plate is pushed out through the second through groove. The second push plate pushes out another fixing plate in the same way. Then, the fixing plate pushes the fixing protrusion to contact the inner wall of the profile. The fixing protrusion deforms the inner wall of the profile, thereby increasing the connection strength of the corner bracket. Through the above structure, when the corner bracket is used to connect the profiles, the fixing protrusion can be used to deform the inner wall of the profile, thereby increasing the connection strength of the corner bracket.

Detailed Implementation
[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0028] Please see Figure 1-9This utility model provides a technical solution: a polyurethane cast two-color profile, including a frame 1, which is composed of four profiles spliced together. A storage groove 3 is formed on the front surface of the lower profile, and a through groove extending into the storage groove 3 is formed on the upper surface of the lower profile. A baffle 4 is slidably connected to the inner wall of the storage groove 3, and a protrusion 5 is fixedly connected to the inner wall of the storage groove 3. A sliding groove 6 is formed on the side of the protrusion 5 away from the storage groove 3. A limiting protrusion 7 is fixedly connected to the side of the baffle 4 near the protrusion 5, and the limiting protrusion 7 is slidably connected to the sliding groove 6. An L-shaped plate 8 is fixedly connected to the rear surface of the baffle 4, and a spring 10 is fixedly connected to the rear surface of the L-shaped plate 8. The rear end of the spring 10 is fixedly connected to the rear inner wall of the storage groove 3. A second protrusion 11 is fixedly connected to the side of the L-shaped plate 8 near the protrusion 5. When cleaning the upper surface of the lower profile, dust and small debris are removed using a brush or similar items. The dirt is pushed into the storage slot 3 through the channel. After multiple cleanings of the storage slot 3 and when a lot of dirt has accumulated, the baffle 4 is pulled. When the baffle 4 is pulled, the L-shaped plate 8 moves simultaneously. At the same time, the movement trajectory of the baffle 4 is limited by the cooperation of the limiting protrusion 7 and the sliding groove 6. When the L-shaped plate 8 moves, the spring 10 is stretched simultaneously, pushing out the dirt inside the storage slot 3. The user can collect the dirt by placing a trash can or similar storage item below the outlet of the storage slot 3. The cooperation of the second protrusion 11 and the protrusion 5 prevents the L-shaped plate 8 from being completely pulled out, which would make it difficult for the user to reset. With the above structure, not only can the dirt be collected using the storage slot 3, but the dirt can also be removed using the L-shaped plate 8. This effectively avoids the problem of the profile joint being difficult to clean, and improves the efficiency and quality of the user when cleaning the grooves on the upper surface of the profile.
[0029] Furthermore, a cleaning plate 12 is fixedly connected to the front surface of the L-shaped plate 8. The front surface of the cleaning plate 12 is inclined. An angle bracket 13 is provided at the junction of the two profiles. The angle bracket 13 is hollow. An installation plate 14 is fixedly connected to the inner wall of the angle bracket 13. A limit rod 15 is fixedly connected to the lower surface of the installation plate 14. A first push plate 16 is slidably connected to the inner wall of the angle bracket 13. The first push plate 16 is slidably sleeved on the outer surface of the limit rod 15. A second push plate 17 is slidably sleeved on the outer surface of the installation plate 14. A limiting groove 18 is formed on the lower surface of the push plate 17. The left and right sides of the limiting groove 18 extend out to the left and right sides of the second push plate 17, respectively. The first push plate 16 is movably connected to the limiting groove 18. The upper and right sides of the corner bracket 13 are respectively provided with second through grooves 19 extending into the interior of the corner bracket 13. The inner wall of the second through groove 19 is slidably connected to a fixing plate 2. The two fixing plates 2 are fixedly connected to a fixing protrusion 9 on the side surface away from the interior of the corner bracket 13. When the L-shaped plate 8 moves, the cleaning plate 1 set at the front can be used. 2. Effectively clean the bottom wall of the storage slot 3. Simultaneously, when splicing the profiles, place the corner bracket 13 at the junction of two profiles. After aligning the profiles, drill holes in each profile, then screw two flat-head screws into the corner bracket 13. Once inside, the two flat-head screws contact the first push plate 16 and the second push plate 17 respectively. As the flat-head screws penetrate deeper, they push the first push plate 16 and the second push plate 17 to move. During the movement of the first push plate 16, the limiting rod 15 limits its movement, ensuring the first push plate... When the first push plate 16 moves, it remains horizontal. After the first push plate 16 moves, it pushes the fixed plate 2 out through the second through groove 19. The second push plate 17 also pushes out another fixed plate 2. Then, the fixed plate 2 pushes the fixed protrusion 9 to contact the inner wall of the profile, and the fixed protrusion 9 causes the inner wall of the profile to deform, thereby increasing the connection strength of the corner bracket 13. Through the above structure, when the corner bracket 13 is used to connect the profile, the fixed protrusion 9 can be used to deform the inner wall of the profile, thereby increasing the connection strength of the corner bracket 13.
[0030] Working Principle: When cleaning the upper surface of the lower profile, dust and small debris are pushed into the collection slot 3 through the channel using a brush or similar tool. After repeated cleaning of the collection slot 3 and when a significant amount of dirt has accumulated, the baffle 4 is pulled. As the baffle 4 is pulled, the L-shaped plate 8 moves synchronously. The movement of the baffle 4 is limited by the cooperation of the limiting protrusion 7 and the sliding groove 6. When the L-shaped plate 8 moves, the spring 10 is stretched, pushing out the dirt from inside the collection slot 3. Users can collect the dirt by placing a trash can or similar container below the outlet of the collection slot 3. The cooperation of the second protrusion 11 and protrusion 5 prevents the L-shaped plate 8 from being completely pulled out, which could make it difficult for the user to reset. When the L-shaped plate 8 moves, the front-tilted cleaning plate 12 effectively collects the dirt. The bottom wall of the slot 3 is cleaned. When splicing the profiles, the corner bracket 13 is placed at the junction of the two profiles. After aligning the profiles, holes are drilled in the profiles. Then, two flat-head screws are screwed into the corner bracket 13. After the two flat-head screws enter, they contact the first push plate 16 and the second push plate 17 respectively. As the flat-head screws go deeper, they will push the first push plate 16 and the second push plate 17 to move. When the first push plate 16 moves, it is limited by the limit rod 15 to ensure that the first push plate 16 remains horizontal. After the first push plate 16 moves, it pushes the fixing plate 2 out through the second through slot 19. The second push plate 17 pushes out the other fixing plate 2. Then, the fixing plate 2 pushes the fixing protrusion 9 to contact the inner wall of the profile, and the fixing protrusion 9 deforms the inner wall of the profile, thereby increasing the connection strength of the corner bracket 13.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
