Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profiles, in particular to a door and window profile supporting mechanism. Background Art

[0002] Aluminum alloy profiles are characterized by light weight and high strength. Since the density of aluminum is low, about 1 / 3 of that of iron, and the strength of aluminum alloys has been significantly improved by adding alloying elements and heat treatment. This allows aluminum alloy profiles to have high bending strength while maintaining light weight, and is suitable for various structural materials that require light weight and strength. Aluminum alloy profiles are easy to process and can be made into various profiles, plates, etc. Its face-centered cubic structure makes aluminum have high plasticity and is easy to process through processes such as cold bending, sawing, drilling, and assembly. In addition, the cross-sectional dimensions of aluminum alloy profiles are precise and the processing accuracy is high, which can meet the manufacturing needs of various complex structures.

[0003] Aluminum alloy profiles have good corrosion resistance. The surface oxide layer does not fade or fall off, and is easy to maintain and does not require frequent repairs. This allows aluminum alloy profiles to maintain good performance when used in outdoor environments or humid conditions. And after anodizing, aluminum alloy profiles can present a variety of colors, such as ancient lead liver copper, golden yellow, silver white, etc., with a beautiful appearance. In addition, the aluminum alloy profile window sash frame is large, and a large area of ​​glass can be inlaid, allowing the indoor light to be sufficient and bright, enhancing the virtual and real contrast between indoor and outdoor, and making the room more layered. Therefore, aluminum alloy profiles are widely used in many fields such as aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industry. For example, in the field of construction, aluminum alloy profiles are mainly used to make doors, windows and curtain walls; in the field of decoration, aluminum alloy profiles can be used to make art frames such as picture frames; in the medical field, aluminum alloy profiles can be used to make stretcher frames, medical equipment, etc.

[0004] When aluminum alloy profiles are used in the field of doors and windows, a structure of fixed frame and movable frame is usually adopted, wherein the movable frame is generally rotatably installed. During the use of the movable frame, due to the looseness of the hinge and the influence of its own gravity, the end of the movable frame away from the hinge is prone to tilt downward, so a supporting mechanism is required to ensure that the movable frame remains stable.

[0032] 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 of 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.

[0033] See also Figure 1-Figure 6 As shown, the utility model is a door and window profile support mechanism, comprising a lower support seat 100 and an upper support seat 200, wherein the lower support seat 100 is mounted on the door and window fixed frame profile, and the upper support seat 200 is mounted on the door and window rotating frame profile, and the lower support seat 100 and the upper support seat 200 cooperate to support the rotating frame profile;

[0034] The lower support seat 100 includes a pulley seat 13 that is clamped at the cavity of the door and window fixing frame profile. The pulley seat 13 is sleeved with a lower support sleeve 11. A support pulley 15 is rotatably mounted on the pulley seat 13. The upper end of the support pulley 15 extends out of the upper surface of the support sleeve 11. A plurality of clamping plates 17 are fixedly arranged on both side walls in the length direction of the pulley seat 13.

[0035] The lower support seat 100 is fixedly clamped to the cavity of the door and window fixing frame profile by the clamping plate 17 to ensure the stability of the installation of the lower support seat 100.

[0036] The upper support seat 200 includes an upper support 21 that is clamped in the cavity of the door and window rotating frame profile. Upper clamping blocks 22 are provided on both sides of the upper support 21. The upper support seat 200 is fixedly clamped in the cavity of the door and window rotating frame profile through the upper clamping blocks 22 to ensure the stability of the installation of the upper support seat 200.

[0037] The two side walls of the short side of the lower support sleeve 11 are fixedly provided with protective clamping joints 12 that match with the clamping plate 17 .

[0038] Since the clamping plate 17 is made of plastic, and the clamping joint 12 and the lower support sleeve 11 are both made of metal, the metal lower support sleeve 11 ensures the overall strength of the entire lower support seat 100 and the stability of the installation of the lower support seat 100 on the one hand, and improves the wear resistance of the lower support seat 100 on the other hand, thereby increasing the service life of the support mechanism.

[0039] By providing a protective card joint 12 to protect the card plate 17, the lower support seat 100 can be pressed directly into the cavity from the cavity opening of the profile, thereby achieving rapid installation of the lower support seat 100 and ensuring stable installation without causing damage to the card plate 17.

[0040] The upper edges of the lower support sleeve 11 are all provided with arc chamfers 111. The setting of the arc chamfers enables the rotating frame profile to move normally to the supporting pulley 15 through the guiding effect of the arc chamfers 111 when it is tilted, ensuring that the rotating frame can rotate normally and thus be supported by the supporting mechanism.

[0041] The pulley seat 13 is provided with a pulley groove 131 for accommodating the supporting pulley 15 , and the side wall of the pulley groove 131 is provided with an axial rod groove 132 , and the pulley shaft 14 is rotatably mounted in the axial rod groove 132 , and the supporting pulley 15 is fixedly mounted on the pulley shaft 14 .

[0043] The support pulley 15 is used to change the sliding friction between the support mechanisms into rolling friction, which can effectively improve the support effect and reduce the friction between the profiles, thereby increasing the service life of the support mechanism.

[0044] The upper end of the position-limiting sealing plate 16 is fixedly provided with a packaging enclosure 162 around it. The arrangement of the packaging enclosure 162 ensures the stability of the installation of the position-limiting sealing plate 16 .

[0045] The clamping plate 17 is provided with a clamping protrusion 171 with a triangular longitudinal section. The triangular clamping protrusion 171 can be inserted into the cavity of the profile, thereby ensuring the stability of the installation of the lower support seat 100.

[0046] Anti-collision inclined plates 23 are fixedly provided on both sides of the lower end of the upper support 21 along the length direction. The setting of the anti-collision inclined plates 23 ensures that the upper support seat 200 can stably support and cooperate with the lower support seat 100 to prevent the rotating frame from overlapping with the fixed frame during rotation when it is tilted, resulting in the inability to rotate and close normally, thereby causing the supporting mechanism to fail to play a supporting effect.

[0047] A wear-resistant top plate 24 is embedded at the center of the lower end of the upper support 21. The wear-resistant top plate 24 is made of metal material, which can effectively reduce the loss during friction and increase the service life of the support mechanism.

[0048] The working principle of the utility model is as follows: the lower support seat 100 is mounted on the door and window fixed frame profile, and the lower support seat 100 is fixedly clamped in the cavity of the door and window fixed frame profile by the clamping plate 17 to ensure the stability of the installation of the lower support seat 100; the upper support seat 200 is mounted on the door and window rotating frame profile, and the upper support seat 200 is fixedly clamped in the cavity of the door and window rotating frame profile by the upper clamping block 22 to ensure the stability of the installation of the upper support seat 200; the cooperation of the lower support seat 100 and the upper support seat 200 is utilized to support the rotating frame to prevent the rotating frame from tilting due to the influence of gravity during use; the support pulley 15 is utilized to change the sliding friction between the support mechanisms into rolling friction, which can effectively improve the support effect and reduce the friction between the profiles, thereby increasing the service life of the support mechanism.
