Description

Technical Field

[0001] The present application relates to the technical field of thermal insulation strips, and in particular to a thermal insulation strip for highly energy-saving windows. Background Art

[0002] The broken bridge structure is to break the whole piece of aluminum alloy in the middle, and use plastic to connect the broken aluminum metal to form a multi-cavity and multi-channel sealing structure design inside the aluminum frame. This structure has good thermal insulation effect. The insulation strip is the plastic strip that connects the aluminum metal in the broken bridge structure. It is widely used in the insulation of doors and windows. The earliest insulation strip was made of PVC, and now most of the market uses nylon.

[0003] In the patent document with the published announcement number CN216197486U, a window frame insulation strip is provided as an insulation component of thermal break aluminum, and its structural composition includes an insulation strip body with a cavity inside, connecting edges are provided at the inner and outer ends of the insulation strip body, a slide groove is provided on at least one side of the insulation strip body in the horizontal direction, and "V"-shaped grooves are provided at the inner and outer ends of the body. This application does not require fillers in the middle, which can save materials and reduce costs. The "V"-shaped groove can optimize the toughness of the insulation strip and extend the service life of the insulation strip.

[0004] However, the connection between the thermal insulation strip and the window frame is only achieved by snapping the connecting edge and the window frame. This connection method makes the connection between the thermal insulation strip and the window frame not firm and easily leads to gaps, and the sealing is poor. It is difficult to realize the design of a multi-cavity and multi-pass sealing structure inside the aluminum frame. Therefore, in view of the above problems, a thermal insulation strip for energy-saving windows is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides an insulation strip for highly energy-saving windows, which overcomes the shortcomings of the prior art and aims to solve the problem of loose connection and poor integrity between the insulation strip and the window frame, and the resulting problem of easy existence of gaps and poor sealing.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A heat-insulating strip for a highly energy-saving window comprises a heat-insulating strip main body, wherein the heat-insulating strip main body comprises an upper connecting plate and a lower connecting plate, a middle strip is connected between the upper connecting plate and the lower connecting plate, a perfusion hole is formed between the upper connecting plate, the lower connecting plate and the middle strip, a foam filling layer is perfused in the perfusion hole, card-jointed foot strips are fixedly provided on both sides of the upper connecting plate, and card-jointed foot strips are fixedly provided on both sides of the lower connecting plate.

[0008] By adopting the above technical scheme, after adding foam filling into the injection hole, due to its curing and expansion characteristics, it will squeeze the middle strip to expand outward. When the middle strip expands outward, it will apply tension to the upper connecting plate and the lower connecting plate due to the elastic force, so that the two have a tendency to move relative to each other. At this time, the clamping foot strips of the upper connecting plate and the lower connecting plate will be in close contact with the slots of the window frame in the vertical direction under the action of the tension, forming the effect of the upper connecting plate and the lower connecting plate "clamping" the slots of the window frame. At the same time, the expansion of the foam filling layer will push the front and rear window frames outward, so that the clamping foot strips of the upper and lower connecting plates will be in close contact with the slots of the window frame in the horizontal direction under the action of the thrust. Under the action of the above-mentioned structural characteristics, the main body of the heat insulation strip can be tightly connected to the rear window frame and the front window frame respectively, thereby improving the integrity and airtightness of the window frame. In particular, the expansion of the foam filling layer will squeeze the middle strip to convexly contact the end faces of the front and rear window frames, further dividing the space between the main body of the heat insulation strip and the rear window frame and the front window frame into two upper and lower parts, thereby enhancing the heat insulation effect.

[0009] As a preferred technical solution of the present application, a rear window frame is arranged behind the insulation strip body, a rear slot is fixedly arranged on the front end surface of the rear window frame, and the connection between the insulation strip body and the rear window frame is achieved by clamping the clamping foot strip in the rear slot.

[0010] By adopting the above technical solution, the firmness and tightness of the connection between the rear window frame and the main body of the heat insulation strip can be achieved, so that the window frame has strong integrity and airtight heat insulation.

[0011] As a preferred technical solution of the present application, a front window frame is arranged in front of the insulation strip body, and a front card slot is fixedly arranged on the front end surface of the front window frame. The connection between the insulation strip body and the front window frame is realized by clamping the card foot strip in the front card slot.

[0012] By adopting the above technical solution, the firmness and tightness of the connection between the front window frame and the main body of the heat insulation strip can be achieved, so that the window frame has strong integrity and airtight heat insulation.

[0013] As a preferred technical solution of the present application, the upper connecting plate and the lower connecting plate are both provided with a plate hollow groove along the axial direction, and two reinforcing strips arranged in an eight-shaped shape are fixedly installed in the plate hollow groove.

[0014] By adopting the above technical solution, the hollow groove in the plate can save materials and reduce the overall weight of the insulation strip body, while the reinforcement strip can compensate for the weakening of the structural strength caused by the hollow groove in the plate.

[0015] As a preferred technical solution of the present application, the middle strip is composed of two outwardly convex elastic rubber strips arranged in a mirror image, and a stop strip is fixedly provided in the middle of the outer side surfaces of the two rubber strips.

[0016] By adopting the above technical solution, the middle strip can be bent outward when under pressure, thereby applying inward pulling force to the upper connecting plate and the lower connecting plate, and the resistance strip can resist the rear window frame or the front window frame when the middle strip is deformed outward to a certain extent, thereby dividing the space between the insulation strip body and the rear window frame and the front window frame into two upper and lower mutually enclosed parts, thereby enhancing the insulation effect.

[0017] As a preferred technical solution of the present application, the resist strip is an elastic rubber long strip structure with a semicircular cross-section and a plurality of concave and convex stripes are arranged on its outer surface along the length direction.

[0018] By adopting the above technical solution, the resistance strip can have a certain deformation ability, and can produce a larger contact area when contacting the rear window frame or the front window frame, thereby enhancing the separation effect.

[0019] As a preferred technical solution of the present application, the upper connecting plate and the lower connecting plate are both curved plate structures as a whole, the upper connecting plate is bent upward, and the lower connecting plate is bent downward.

[0020] By adopting the above technical solution, the upper connecting plate and the lower connecting plate can form an arch-like stress effect, so that the two will not have excessive deformation under the action of tension, and have a strong bearing capacity.

[0021] The beneficial effects of the present application are as follows: the solidification expansion of the foam filling layer will squeeze the middle strip outward, thereby applying a pulling force in opposite directions to the upper connecting plate and the lower connecting plate, so that the two have a tendency to move relative to each other, so that the clamping foot strips of the two are in close contact with the slots of the window frame, forming an effect of the upper connecting plate and the lower connecting plate "clamping" the slots of the window frame. At the same time, the expansion of the foam filling layer will push the front and rear window frames outward, so that the clamping foot strips of the two are in close contact with the slots of the window frames in the horizontal direction under the action of the thrust, thereby improving the integrity and airtightness of the window frames. In particular, the expansion of the foam filling layer will squeeze the middle strip outward to contact the end faces of the front and rear window frames, further dividing the space between the main body of the insulation strip and the rear window frame and the front window frame into two upper and lower parts, thereby enhancing the insulation effect.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Reference Figure 1-3 A heat-insulating strip for a high energy-saving window comprises a heat-insulating strip body 1, the heat-insulating strip body 1 comprises an upper connecting plate 11 and a lower connecting plate 12, a middle strip 13 is connected between the upper connecting plate 11 and the lower connecting plate 12, a perfusion hole 14 is formed between the upper connecting plate 11, the lower connecting plate 12 and the middle strip 13, a foam filling layer 4 is filled in the perfusion hole 14, both sides of the upper connecting plate 11 are fixedly provided with a card-jointed foot strip 15, and both sides of the lower connecting plate 12 are fixedly provided with a card-jointed foot strip 15. By adopting the above technical scheme, after the foam filling layer 4 is added to the perfusion hole 14, due to its curing and expansion characteristics, it will cause it to squeeze the middle strip 13 to expand outwards. When the middle strip 13 expands outwards, it will apply tension to the upper connecting plate 11 and the lower connecting plate 12 due to the elastic force, so that the two have a tendency to move relative to each other. At the same time, the clamping foot strips 15 of the upper connecting plate 11 and the lower connecting plate 12 will be in close contact with the slots of the window frame in the vertical direction under the action of the pulling force, forming the effect of the upper connecting plate 11 and the lower connecting plate 12 "clamping" the slots of the window frame, and at the same time, the expansion of the foam filling layer 4 will push the window frame outward, so that the clamping foot strips 15 of the upper connecting plate 11 and the lower connecting plate 12 are in close contact with the slots of the window frame in the horizontal direction under the action of the thrust. Under the action of the above-mentioned structural characteristics, the insulation strip body 1 can be tightly connected with the rear window frame 2 and the front window frame 3 respectively, thereby improving the integrity and airtightness of the window frame. In particular, the expansion of the foam filling layer 4 will squeeze the middle strip 13 to convexly contact the end face of the window frame, further dividing the space between the insulation strip body 1 and the rear window frame 2, the front window frame 3 into two upper and lower parts, thereby enhancing the insulation effect.

[0030] Reference Figure 4 A rear window frame 2 is arranged behind the insulation strip main body 1, and a rear slot 21 is fixedly arranged on the front end surface of the rear window frame 2. The connection between the insulation strip main body 1 and the rear window frame 2 is realized by a clamping foot strip 15 clamped in the rear slot 21. A front window frame 3 is arranged in front of the insulation strip main body 1, and a front slot 31 is fixedly arranged on the front end surface of the front window frame 3. The connection between the insulation strip main body 1 and the front window frame 3 is realized by a clamping foot strip 15 clamped in the front slot 31. By adopting the above technical scheme, the firmness and tightness of the connection between the rear window frame 2 or the front window frame 3 and the insulation strip main body 1 can be achieved, so that the window frame has strong integrity and airtight heat insulation.

[0031] Reference Figure 2 A hollow plate groove 16 is provided in the upper connecting plate 11 and the lower connecting plate 12 along the axial direction, and two reinforcing strips 17 arranged in an eight-shaped shape are fixedly arranged in the hollow plate groove 16. By adopting the above technical scheme, the hollow plate groove 16 can save materials and reduce the overall weight of the insulation strip body 1, and the reinforcing strip 17 can make up for the weakening of the structural strength caused by the opening of the hollow plate groove 16.

[0032] Reference Figure 2 The middle strip 13 is composed of two outwardly convex elastic rubber strips arranged in a mirror image, and a resist strip 18 is fixedly arranged in the middle of the outer side surfaces of the two rubber strips. The resist strip 18 is an elastic rubber long strip structure with a semicircular cross-section and a plurality of concave and convex stripes are arranged along the length direction on its outer side surface. By adopting the above technical scheme, the middle strip 13 can be bent outward when under pressure, thereby applying an inward pulling force to the upper connecting plate 11 and the lower connecting plate 12, and the resist strip 18 can resist the rear window frame 2 or the front window frame 3 when the middle strip 13 is deformed outward to a certain extent, thereby dividing the space between the insulation strip body 1 and the rear window frame 2, the front window frame 3 into two upper and lower mutually enclosed parts, thereby enhancing the heat insulation effect.

[0033] Reference Figure 2 The upper connecting plate 11 and the lower connecting plate 12 are both curved plate structures as a whole. The upper connecting plate 11 is bent upward, and the lower connecting plate 12 is bent downward. This structural form can make the upper connecting plate 11 and the lower connecting plate 12 form an arch-like force effect, so that the two will not have excessive deformation under the action of tension, and have a strong bearing capacity.

[0034] Working principle: The insulation strip body 1 is connected to the upper connecting plate 11 and the lower connecting plate 12 through the clamping foot strip 15. After the foam filling layer 4 is added to the injection hole 14, due to its curing and expansion characteristics, it will cause it to squeeze the middle strip 13 to expand outward. When the middle strip 13 expands outward, it will apply tension to the upper connecting plate 11 and the lower connecting plate 12 due to the elastic force, so that the two have a relative movement tendency. At this time, the clamping foot strips 15 of the upper connecting plate 11 and the lower connecting plate 12 will be in close contact with the slot of the window frame in the vertical direction under the action of the tension, forming the upper connecting plate 11 and the lower connecting plate 12 "clamping" the slot of the window frame At the same time, the expansion of the foam filling layer 4 will push the window frame outward, so that the card foot strips 15 of the upper connecting plate 11 and the lower connecting plate 12 are in close contact with the card grooves of the window frame in the horizontal direction under the action of the thrust. Under the action of the above-mentioned structural characteristics, the insulation strip body 1 can be tightly connected with the rear window frame 2 and the front window frame 3 respectively, thereby improving the integrity and airtightness of the window frame. In particular, the expansion of the foam filling layer 4 will squeeze the middle strip 13 to bulge outward so that the resistance strip 18 contacts the end face of the window frame, further dividing the space between the insulation strip body 1 and the rear window frame 2 and the front window frame 3 into two upper and lower parts, thereby enhancing the heat insulation effect.
