Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water-blocking profiles, and particularly relates to a water-blocking profile. Background Art
[0002] Water-blocking profiles are building materials specifically designed to prevent water penetration. They usually have excellent waterproof performance and can provide a reliable waterproof barrier in different building structures to protect buildings from water damage. The application fields of water-blocking profiles are extensive, including but not limited to building roofs, basements, kitchens, bathrooms, and other areas that may come into contact with water. These materials can effectively extend the service life of buildings and reduce maintenance costs caused by water damage.
[0003] A method of adding a water-blocking strip to the profile installation space is used to improve the energy-saving and heat-insulating effect of aluminum alloy doors and windows. However, aluminum alloy doors and windows often come into contact with rainwater. Even through the design of an equal-pressure chamber, it is still impossible to avoid the heat-insulating strip from coming into contact with water, resulting in the expansion and dimensional deformation of the heat-insulating strip after absorbing water and being unable to block the water flow, causing water penetration. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a water-blocking profile, which solves the problem that the heat-insulating strip comes into contact with water, resulting in the expansion and dimensional deformation of the heat-insulating strip after absorbing water and being unable to block the water flow, causing water penetration.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A water-blocking profile includes an L-shaped connecting profile. Both sides of the L-shaped connecting profile are provided with flat parts. The flat parts are in an L-shaped structure. In the middle of one side perpendicular to the surface of the flat part, a first sealing rubber strip is provided. On one side of the flat part close to the first sealing rubber strip, a connecting part is provided. One end of the connecting part is provided with an inverted hook groove. The inverted hook groove is movably adapted to one side of the first sealing rubber strip. The top of the L-shaped connecting profile is provided with an overlapping part. The lower surface of the overlapping part is provided with a groove. In the middle of the upper surface of the horizontal flat part, a second sealing rubber strip is provided. It is overlapped on the surface of the vertical profile plate through the inverted hook groove. Because there will be friction between the rubber and the profile plate, it is overlapped on the surface of the profile plate. When rainwater flows down from the profile part, it will flow out from the surface of the inverted hook groove. Because the inverted hook groove is in an arc structure, the rainwater is guided. In order to enhance the sealing performance, the first sealing rubber strip and the second sealing rubber strip are attached to the vertical and horizontal profile plates, thereby further enhancing the sealing performance.
[0006] Optionally, a first hollow groove is formed between the first sealing rubber strip and the upper surface of the connecting part, and a second hollow groove is formed between the second sealing rubber strip and the lower surface of the connecting part.
[0007] Optionally, a profile plate is movably lapped between the first hollow groove and the second hollow groove. There are two profile plates. One of the profile plates is placed horizontally, and the other profile plate is placed vertically.
[0008] Optionally, the horizontally placed profile plate is movably lapped with the second sealing strip, and the lower surface of the vertically placed profile plate is movably clamped in the barb groove.
[0009] Optionally, one side of the lapping portion is movably sleeved on the surface of the profile plate, and a transition inclined surface is provided on the upper surface flat portion of the L-shaped connecting profile.
[0010] Optionally, a sealing portion is provided on the upper surface of the transition inclined surface, and the upper surface of the sealing portion is movably lapped with the lower surface of the profile plate.
[0011] Optionally, the top lapping portion of the L-shaped connecting profile is an elastic structure. The L-shaped connecting profile is made of aluminum alloy. Due to the transition inclined surface on one side of the upper surface of the L-shaped connecting profile, the infiltrated rainwater will slide out of the profile from the surface. Therefore, the multi-edge design can effectively prevent rainwater from entering, and the waterproof effect is good. Coupled with the good elasticity of the sealing strip, it fits tightly with the attachment frame, further blocking the water flow.
[0012] The utility model provides a water-blocking profile, which has the following beneficial effects:
[0013] 1. It is lapped on the surface of the vertical profile plate through the barb groove. Since there is friction between the rubber and the profile plate, it is lapped on the surface of the profile plate. When rainwater flows down from the profile part, it will flow out from the surface of the barb groove. Because the barb groove is an arc structure, it guides the rainwater. In order to enhance the sealing performance, the first sealing strip and the second sealing strip are attached to the vertical and horizontal profile plates, further enhancing the sealing performance.
[0014] 2. Due to the transition inclined surface on one side of the upper surface of the L-shaped connecting profile, the infiltrated rainwater will slide out of the profile from the surface. Therefore, the multi-edge design can effectively prevent rainwater from entering, and the waterproof effect is good. Coupled with the good elasticity of the sealing strip, it fits tightly with the attachment frame, further blocking the water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The structures, ratios, sizes, etc. disclosed in this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present utility model. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model.
[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a water-blocking profile, including an L-shaped connecting profile 1. Both sides of the L-shaped connecting profile 1 are provided with flat parts 101. The flat parts 101 are in an L-shaped structure. The middle of one side perpendicular to the surface of the flat part 101 is provided with a first sealing strip 102. One side of the flat part 101 close to the first sealing strip 102 is provided with a connecting part 2. One end of the connecting part 2 is provided with a barbed groove 201. The barbed groove 201 is movably adapted to the first sealing strip 102 on one side. The top of the L-shaped connecting profile 1 is provided with an overlapping part 3. The lower surface of the overlapping part 3 is provided with a groove 301. The middle of the upper surface of the horizontal flat part 101 is provided with a second sealing strip 103.
[0023] It is lapped on the surface of the vertical profile plate 6 through the barbed groove 201. Due to the friction between the rubber and the profile plate 6, it is lapped on the surface of the profile plate 6. When rainwater flows down from the profile part, it will flow out from the surface of the barbed groove 201. Since the barbed groove 201 is in an arc structure, the rainwater is guided. In order to enhance the sealing performance, the first sealing strip 102 and the second sealing strip 103 are attached to the vertical and horizontal profile plates 6, thereby further enhancing the sealing performance.
[0024] A first hollow groove 4 is formed between the first sealing strip 102 and the upper surface of the connecting portion 2, and a second hollow groove 5 is formed between the second sealing strip 103 and the lower surface of the connecting portion 2. There is an overlapping connection between the first hollow groove 4 and the second hollow groove 5 with a profile plate 6. There are two profile plates 6. One of the profile plates 6 is horizontally placed, and the other profile plate 6 is vertically placed. The horizontally placed profile plate 6 is in overlapping connection with the second sealing strip 103. The lower surface of the vertically placed profile plate 6 is snap-fitted into the barb groove 201. One side of the overlapping portion 3 is sleeved on the surface of the profile plate 6. There is a transition slope 7 on the upper surface flat portion 101 of the L-shaped connecting profile 1. There is a sealing portion 701 on the upper surface of the transition slope 7. The upper surface of the sealing portion 701 is in overlapping connection with the lower surface of the profile plate 6. The overlapping portion 3 at the top of the L-shaped connecting profile 1 is an elastic structure. The L-shaped connecting profile 1 is made of aluminum alloy material.
[0025] Due to the transition slope 7 on one side of the upper surface of the L-shaped connecting profile 1, the infiltrated rainwater will slide out of the profile from the surface. Therefore, with the multi-edge design, it can effectively prevent rainwater from entering, and has a good waterproof effect. Coupled with the fact that the sealing strip has good elasticity and fits tightly with the auxiliary frame, it further blocks the water flow.
[0026] In the present utility model, the working steps of the device are as follows:
[0027] The vertically placed profile plate 6 is inserted into the connecting portion 2 in an overlapping manner. One end of the barb groove 201 is made of rubber material. Therefore, the barb groove 201 overlaps on the surface of the vertically placed profile plate 6. Due to the friction between the rubber and the profile plate 6, it overlaps on the surface of the profile plate 6. When the rainwater flows down from the profile part, it will flow out from the surface of the barb groove 201. Since the barb groove 201 is an arc-shaped structure, it guides the rainwater. In order to enhance the sealing performance, the first sealing strip 102 and the second sealing strip 103 are attached to the vertical and horizontal profile plates 6, thereby further enhancing the sealing performance. When the rubber strip comes into contact with the profile plate 6, it will deform and move relative to the profile plate 6. Therefore, due to the pressing of the profile plate 6, a seal is formed to achieve the sealing effect. The transition slope 7 on one side of the upper surface of the L-shaped connecting profile 1 allows the infiltrated rainwater to slide out of the profile from the surface. Therefore, with the multi-edge design, it can effectively prevent rainwater from entering, and has a good waterproof effect. Coupled with the fact that the sealing strip has good elasticity and fits tightly with the auxiliary frame, it further blocks the water flow.
[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
