Description

Technical Field

[0001] This utility model relates to the field of building door and window profile technology, and in particular to a strip-type heat-insulating aluminum alloy profile hardware groove. Background Technology

[0002] Traditional through-bar thermal insulation aluminum alloy profiles are composite aluminum alloy profiles with thermal insulation function, formed by structurally connecting aluminum alloy profiles and thermal insulation strips through processes such as toothing, strip insertion, and rolling. It consists of three parts: an inner aluminum alloy profile 1, an outer aluminum alloy profile 2, and a thermal insulation strip A3 connecting the inner and outer aluminum alloy profiles (see...). Figure 1 The inner aluminum alloy profile 1 is designed with clamps A101 and B102; the outer aluminum alloy profile 2 is designed with clamps C201 and D202. During the composite process, the two thermal insulation strips A3 are first inserted between the clamps on the inner aluminum alloy profile 1 and the outer aluminum alloy profile 2. Then, rollers 4 on a special rolling equipment are used to roll the clamps A101 and C201, and clamps B102 and D202 from the left and right sides respectively, deforming them and clamping the thermal insulation strips A3. This connects the inner aluminum alloy profile 1, the outer aluminum alloy profile 2 and the thermal insulation strips A3 into a whole, forming a strip-type thermal insulation aluminum alloy profile. The thermal break strip A3 is made of polyamide nylon 66 with 25% added glass fiber. Its thermal conductivity is 0.3 W / m·K, significantly better than aluminum alloy with a thermal conductivity of 160 W / m·K. In winter, it effectively reduces heat loss to the outside, and in summer, it effectively reduces heat transfer from the outside to the inside. This allows aluminum alloy doors and windows made with this type of thermal break strip to achieve excellent thermal insulation. The larger the cross-sectional width of the thermal break strip A3, the better the thermal insulation effect of the composite profile.

[0003] However, conventional aluminum alloy doors and windows use strip-type insulated aluminum alloy profiles to make the frame. A handle 6 installed on the frame drives a transmission rod 7 to slide, which in turn moves the locking point 5 connected to the transmission rod 7, thus achieving opening or locking functions (see...). Figure 2 To facilitate the installation of the transmission rod 7, a corresponding hardware slot needs to be designed on the profile to allow the transmission rod 7 to pass through and slide smoothly. Therefore, the dimensions of the hardware slot must meet certain requirements. The standard hardware slot is C-shaped, formed by the protrusion A103 and collet A101 on the inner aluminum alloy profile 1, and the protrusion B203 and collet C201 on the outer aluminum alloy profile 2 (see...). Figure 3Furthermore, the groove width 'a', groove width 'b', and groove depth 'c' all have dimensional requirements, and standard hardware parts and transmission rods are designed and manufactured according to these hardware groove dimensions. To ensure that the roller 4 can fully press against the chucks A101 and C201 during rolling, chuck A101 must have a certain misalignment with protrusion A103, and chuck C201 must also have a certain misalignment with protrusion B203. That is, the misalignment dimension 'd' is usually greater than 3mm; otherwise, the roller 4 will be blocked by protrusions A103 and B203. Therefore, while ensuring the groove width 'a', the distance between chucks A101 and C201 is limited, resulting in a limitation on the cross-sectional width dimension 'e' of the heat insulation strip A3, which is approximately the same width as 'a'.

[0004] Therefore, if a wider cross-sectional thermal insulation strip is desired to improve the thermal insulation performance of the profile, the hardware groove design needs to be modified. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model discloses a strip-type heat-insulating aluminum alloy profile hardware groove.

[0006] The specific technical solution is as follows:

[0007] A strip-type heat-insulating aluminum alloy profile hardware slot is provided, wherein the hardware slot is formed on an inner aluminum alloy profile and an outer aluminum alloy profile. The clamp A of the inner aluminum alloy profile is extended into an extended clamp A, and the clamp C of the outer aluminum alloy profile is extended into an extended clamp B. Heat-insulating strips B and C are installed in the hardware slot. The width of heat-insulating strip B is extended to e'. The cross-sectional shape of heat-insulating strip C is a concave shape with a groove in the middle, wider at both ends and narrower in the middle. The groove width is b and the groove depth is c. The slot width formed between the extended clamp A and the extended clamp B is a, which is consistent with the dimensions of a standard hardware slot.

[0008] The heat insulation strips B and C are made of polyamide nylon 66 with 25% glass fiber added, and have a thermal conductivity of 0.3 W / m·K.

[0009] Compared with the prior art, the present invention has the following beneficial technical effects:

[0010] The extended clamps A and B of this invention can, after roll forming, together with the groove on the thermal insulation strip C, form a C-shaped hardware slot, and the slot width, groove depth c are the same as the standard hardware slot dimensions. In this way, the cross-sectional width e' of the thermal insulation strips C and B can be greatly widened, even reaching a width of 3a, far greater than a, which can significantly improve the thermal insulation performance of the profile.

[0011] This invention significantly increases the width of the heat insulation strip at the hardware slot while ensuring that the dimensions are the same as the standard hardware slot. This greatly improves the heat insulation performance of the through-strip heat-insulating aluminum alloy profile, while taking into account both standard compatibility and heat insulation performance.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0019] Figure 4The figure shows a schematic diagram of the hardware slot structure of this utility model: The hardware slot of this utility model, a strip-type heat-insulating aluminum alloy profile, is formed on the inner aluminum alloy profile 1 and the outer aluminum alloy profile 2. The clamp A101 of the inner aluminum alloy profile 1 is extended into an extended clamp A104, and the clamp C201 of the outer aluminum alloy profile 2 is extended into an extended clamp B204. Heat-insulating strips B8 and C9 are installed inside the hardware slot. The width of heat-insulating strip B8 is extended to e', and the cross-section of heat-insulating strip C9... The shape is a concave "U" shape with a groove 901 in the middle, wider at both ends and narrower in the middle. The groove 901 has a groove width of b and a groove depth of c. The slot width formed between the extended chuck A104 and the extended chuck B204 is a, which is consistent with the size of the standard hardware slot. After the extended chuck A104 and the extended chuck B204 are rolled and laminated, they can form a C-shaped hardware slot together with the groove 901 on the heat insulation strip C9, and make the slot width a, groove width b and groove depth c the same as the size of the standard hardware slot. In this way, the cross-sectional width e' of thermal break strips C9 and B8 can be greatly widened, even reaching a width of 3a, which is much larger than a. This can greatly improve the thermal insulation performance of the profile. Thermal break strips B8 and C9 are made of polyamide nylon 66 material with 25% glass fiber added. Its thermal conductivity is 0.3W / m·K, which is much better than that of aluminum alloy with a thermal conductivity of 160W / m·K. In winter, it can effectively reduce heat loss to the outside and in summer, it can effectively reduce the transfer of external heat to the inside. The thermal insulation effect is better than that of conventional doors and windows.
