Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a high-sealing building door and window sealing strip. Background Technology

[0002] As an important sealing material, door and window sealing strips are widely used in various parts of doors and windows, including key areas such as frames and sashes. They are usually carefully made of different materials such as rubber and silicone, and their main function is to provide effective waterproof and dustproof protection. By installing these sealing strips, rainwater and dust can be effectively prevented from entering, thereby keeping the indoor environment clean and dry. In addition, some high-quality door and window sealing strips also have additional functions, such as sound insulation and heat insulation, which makes them play an important role in improving living comfort.

[0003] The existing patent "A door and window sealing strip with a buffer structure (Publication No.: CN222848029U)" discloses that "This utility model discloses a door and window sealing strip with a buffer structure, belonging to the field of building door and window technology. A door and window sealing strip with a buffer structure includes a rubber strip body and an adhesive layer coated on the lower surface of the rubber strip body. The inner side of the rubber strip body has a hollow structure with a buffer cavity, and the inner side of the buffer cavity is provided with partitions at equal intervals. The edge of the upper surface of the rubber strip body is provided with a boss, and the inner side of the boss is provided with an energy-absorbing protrusion connected to the rubber strip body. Multiple energy-absorbing protrusions are provided at equal intervals, and a pressure relief groove is provided between two adjacent energy-absorbing protrusions. It can effectively dissipate and buffer the impact force generated during the closing of doors and windows, and avoid the rebound force generated by the rubber strip body from acting on the doors and windows to form large vibrations."

[0004] In the aforementioned patent, the impact force is reduced and buffered by the cooperation of foam cotton and energy-absorbing protrusions. However, the foam cotton has multiple pores. Long-term pressure from doors and windows may cause the pores in the foam cotton to collapse, which may lead to permanent deformation of the foam cotton. The thinned foam cotton may not be able to fit tightly with the door and window structure, which may lead to insufficient sealing between doors and windows. In addition, the foam cotton and the main body of the sealing strip are designed as an integral unit, and the foam cotton usually ages and deforms faster than the main body of the sealing strip. When the foam cotton ages and deforms, it is difficult to disassemble it separately, and the entire sealing strip may need to be replaced, which may increase maintenance costs.

[0005] Therefore, those skilled in the art have provided a high-sealing building door and window sealing strip to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-sealing building door and window sealing strip that can ensure the airtightness of doors and windows while reducing maintenance costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A high-sealing building door and window sealing strip includes a main body, an adhesive mechanism at the lower end of the main body, and a buffer mechanism at the upper end of the main body; The main structure includes a rubber strip body and a rubber sleeve. The rubber strip body includes a rubber layer and a sponge layer. Multiple vent holes are provided at both the front and rear ends of the rubber strip body. A sealing lip is fixedly provided at the upper end of the rubber strip body near the rear end. Multiple slots are provided at the upper end of the rubber strip body. Multiple limiting posts are fixedly provided at the lower end of the rubber sleeve. The adhesive mechanism includes an adhesive layer, and a magnetic strip is embedded in the middle of the adhesive layer; The buffer mechanism includes two upper buffer layers and a lower buffer layer, and the upper end of the lower buffer layer is provided with multiple limiting holes.

[0008] Furthermore, the sponge layer is fixedly sleeved inside the rubber layer, and the plurality of ventilation holes are respectively opened at the front and rear ends of the rubber layer.

[0009] Furthermore, the rubber sleeve is located at the upper end of the buffer mechanism, and the rubber sleeve is located at the upper end of the lower buffer layer.

[0010] Furthermore, the positions of the plurality of limiting posts correspond one-to-one with the positions of the plurality of limiting holes, the outer surfaces of the plurality of limiting posts are respectively fitted into the plurality of limiting holes near the upper end, and the outer surfaces of the plurality of limiting posts are respectively fitted into the plurality of slots near the lower end.

[0011] Furthermore, the adhesive layer is fixedly disposed at the lower end of the adhesive strip body, and the magnetic strip is fixedly disposed at the lower end of the adhesive strip body.

[0012] Furthermore, both upper buffer layers are fixedly disposed on the upper end of the lower buffer layer, which is located between the rubber strip body and the rubber sleeve.

[0013] Furthermore, the multiple limiting holes correspond one-to-one with the multiple slot positions, and both upper buffer layers are sleeved in the rubber sleeve.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a high-sealing building door and window sealing strip, which is provided with a main body and a buffering mechanism. During use, the impact and squeezing between doors and windows mainly act on the main body of the sealing strip and the buffering mechanism. The buffering structure uses a low-density upper buffering layer to absorb the impact, while the main body of the sealing strip dissipates energy through the synergistic energy dissipation effect of the rubber layer and the buffering sponge layer. The dual structure can significantly improve the buffering performance. At the same time, the sealing strip is provided with a sealing lip perpendicular to the buffering mechanism. The sealing lip will not deform due to squeezing, which can effectively ensure the sealing effect between doors and windows.

[0015] 2. This utility model proposes a high-sealing building door and window sealing strip. The sealing strip is equipped with a buffer mechanism. During use, the buffer mechanism adopts a modular design and is equipped with multiple limiting holes. The sealing strip body is equipped with a corresponding slot. The limiting post on the rubber sleeve can pass through the slot and limiting hole, and the stability of the sleeve is ensured by friction. The buffer mechanism is fixed by the clamping action of the rubber sleeve and the sealing strip body. This detachable modular design significantly reduces the maintenance cost of the sealing strip.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1An embodiment of this utility model is provided: a high-sealing building door and window sealing strip, including a main body 1, an adhesive mechanism 2 provided at the lower end of the main body 1, and a buffer mechanism 3 provided at the upper end of the main body 1; Specifically, the main body 1 is the main part of the adhesive strip, the adhesive mechanism 2 is used to fix the adhesive strip to the outer frame of the door and window, and the buffer mechanism 3 is used to improve the buffering effect of the adhesive strip; It should be noted that the main body 1 is an independent adhesive strip. In actual use, multiple adhesive strips need to be spliced ​​together.

[0020] Reference Figure 2-4 The main body 1 includes a rubber strip body 101 and a rubber sleeve 105. The rubber strip body 101 includes a rubber layer 10101 and a sponge layer 10102. Multiple vent holes 103 are provided at both the front and rear ends of the rubber strip body 101. A sealing lip 102 is fixedly provided at the upper end of the rubber strip body 101 near the rear end. Multiple slots 104 are provided at the upper end of the rubber strip body 101. Multiple limiting posts 106 are fixedly provided at the lower end of the rubber sleeve 105. The sponge layer 10102 is fixedly sleeved inside the rubber layer 10101. Multiple vent holes 103 are respectively opened at the front and rear ends of the rubber layer 10101. The rubber sleeve 105 is located at the upper end of the buffer mechanism 3 and at the upper end of the lower buffer layer 302. Multiple limiting posts 106 correspond one-to-one with the positions of multiple limiting holes 303. The outer surfaces of the multiple limiting posts 106 are respectively sleeved in the multiple limiting holes 303 near the upper end, and the outer surfaces of the multiple limiting posts 106 are respectively sleeved in the multiple slots 104 near the lower end. Specifically, the main body 101 of the rubber strip is the main part of the rubber strip. Its outer layer is a rubber layer 10101 made of high elastic rubber. A sponge layer 10102 is embedded inside the rubber layer 10101. The elasticity of the rubber layer 10101 is relatively weak, but it provides the main support for the rubber strip. Although the sponge layer 10102 has relatively weak support, it is the main source of the rubber strip's cushioning effect. The sponge layer 10102 has a porous structure and has a certain buffering and energy dissipation effect when it is squeezed. Furthermore, fine vent holes 103 are opened at both the front and rear ends of the rubber layer 10101. The vent holes 103 can ensure that gas enters and exits the rubber layer 10101, effectively balancing the air pressure inside the rubber layer 10101 when the rubber strip is squeezed. It should be noted that the vent 103 is relatively fine, which can ensure that air can pass through the rubber layer 10101 to balance the air pressure inside and outside when the rubber strip body 1 is compressed, and also ensure the supporting function of the rubber layer 10101. In addition, when the rubber layer 10101 is squeezed, the gas in the foam cells of the sponge layer 10102 is squeezed out and discharged outward through the vent 103 to ensure air pressure balance. During the outward impact of air, the vent 103 can be cleaned at the same time to prevent dust from clogging the vent 103. Furthermore, external air can also smoothly enter the interior of the rubber strip body 101 to ensure the rebound effect of the sponge layer 10102. The sealing lip 102 is located on one side of the rubber strip, which can fit the door and window structure well and avoid the sealing effect of the door and window due to the compression of the buffer mechanism 3. The rubber sleeve 105, the limiting post 106 and the rubber layer 10101 are made of the same rubber. The cross-section of the rubber sleeve 105 is "E" shaped, which can be snapped onto the outer surface of the two upper buffer layers 301. The limiting post 106 can be snapped into the slot 104. The rubber sleeve 105 and the rubber strip body 101 are connected through the snapping action. At the same time, the two can clamp and fix the buffer mechanism 3. It should be noted that when the limiting post 106 is inserted into the slot 104, it will be squeezed by the slot 104. The rebound of the rubber will increase the friction between the two. At the same time, since the two are made of the same material, the molecular chains are more likely to entangle with each other, further increasing the frictional resistance. This can ensure the stable engagement of the limiting post 106 and the slot 104. In addition, the squeezing action of the door and window on the rubber strip will also make the rubber sleeve 105 stick tightly to the rubber layer 10101. Therefore, the limiting post 106 will only be separated from the slot 104 by manually peeling the rubber sleeve 105 outward.

[0021] Reference Figure 3 The adhesive mechanism 2 includes an adhesive layer 201, and a magnetic strip 202 is embedded in the middle of the adhesive layer 201; The adhesive layer 201 is fixedly disposed at the lower end of the adhesive strip body 101, and the magnetic strip 202 is fixedly disposed at the lower end of the adhesive strip body 101; Specifically, the adhesive layer 201 can directly fix the adhesive strip to the door and window frame. At the same time, since the door and window frame is generally made of alloy material, it can generate an attractive force with the magnet. The attractive force of the magnetic strip 202 can strengthen the fixation of the adhesive strip. This dual fixing mechanism ensures the stability of the adhesive strip. It should be noted that when the adhesive strip is not in use, there is a protective film at the bottom of the adhesive layer 201. When the adhesive strip is needed, the protective film needs to be peeled off and the adhesive layer 201 should be pasted onto the door and window frame.

[0022] Reference Figure 2 , Figure 4The buffer mechanism 3 includes two upper buffer layers 301 and a lower buffer layer 302, and the upper end of the lower buffer layer 302 is provided with multiple limiting holes 303; Both upper buffer layers 301 are fixedly installed on the upper end of the lower buffer layer 302. The lower buffer layer 302 is located between the rubber strip body 101 and the rubber sleeve 105. Multiple limiting holes 303 correspond one-to-one with multiple slots 104. Both upper buffer layers 301 are sleeved in the rubber sleeve 105. Specifically, the lower buffer layer 302 is made of the same material as the rubber sleeve 105 and the rubber strip body 101, so that the three are subjected to uniform force and compressed to the same degree when squeezed. The upper buffer layer 301 is made of low-density rubber material. Compared with the lower buffer layer 302, although its support is weaker, its elasticity is better and it can play an effective buffering role.

[0023] Working principle: When using this adhesive strip, peel off the protective film and stick the adhesive layer 201 to the appropriate position on the door and window frame. At the same time, the magnetic strip 202 and the metal frame generate an attraction force, which fixes the adhesive strip body 101 to the door and window frame. When the rubber strip is impacted or squeezed, the impact force is applied to the upper buffer layer 301. The upper buffer layer 301 relieves the impact force through compression. At the same time, the lower buffer layer 302 and the rubber layer 10101 at its lower end are also compressed, and the impact force is reduced to a certain extent. Meanwhile, the sponge layer 10102 inside the rubber layer 10101 is also squeezed. The impact force compresses the bubble cells, and the air is squeezed out. The kinetic energy brought by the remaining impact force is converted into the elastic potential energy of the sponge layer 10102. Finally, the buffering process is completed through the friction of the bubble cell wall and the flow of gas. Afterwards, the air will re-enter the sponge layer 10102 through the vent 103, causing the sponge layer 10102 to rebound for the next use. During this process, the sealing lip 102 is not squeezed, which can ensure the sealing effect of the door and window. When it is necessary to replace the buffer mechanism 3, hold the old buffer mechanism 3 with one hand and pull the rubber sleeve 105 outward with the other hand. Release the limiting post 106 from the slot 104 and the limiting hole 303 in sequence. At this time, the buffer mechanism 3 can be replaced. The limiting hole 303 on the buffer mechanism 3 corresponds one-to-one with the slot 104. Reinsert the limiting post 106 into the limiting hole 303 and the slot 104 to fix the buffer mechanism 3 stably on the rubber strip body 101.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
