Description

Technical Field

[0001] The utility model relates to the field of wool strips, and further relates to door and window sealing wool strips. Background Art

[0002] The wool strip is a supporting product for doors and windows. It is widely used in the sealing of doors and windows in buildings, automobiles, ships, etc. It is mainly composed of a base plate and sealing wool. When installing, the wool strip needs to be inserted into the T-slot from one end of the window frame. In order to ensure that the wool strip is smoothly inserted into the T-slot, the thickness of the wool strip base plate needs to be less than the notch depth of the T-slot. Due to the mismatch between the thickness of the wool strip base plate and the notch depth, the wool strip in the installation direction is prone to displacement, which reduces the sealing performance and affects the use effect. Utility Model Content

[0003] In response to the above technical problems, the purpose of the utility model is to provide a sealing wool strip for doors and windows. The buffer pad on the bottom plate undergoes elastic deformation under the action of pressure, filling the gap between the bottom plate and the T-slot, forming interference between the wool strip and the doors and windows, avoiding the problem of overall movement of the wool strip due to mismatch of the wool strip size, improving the compatibility of the wool strip, and making the wool strip adapt to more scenarios.

[0024] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0025] refer to Figures 1 to 3According to a preferred embodiment of the utility model, the wool strip is assembled in the T-slot of the door and window, and is an indispensable component of the door and window system, ensuring that the door and window have excellent sealing, sound insulation, waterproof and dustproof performance to achieve the best use effect.

[0026] The wool strip comprises a base plate 1 and sealing wool 2 installed on the base plate 1 .

[0027] The sealing hair 2 is the key to the performance of the wool strip, and should have good sealing performance and wear resistance. The material of the sealing hair 2 is not specifically limited in this embodiment, and non-limiting examples may include at least one selected from the following materials: rubber, polyurethane, fluororubber, silicone, etc. For example, the wool strip is made of polypropylene. When the sealing hair 2 is made of polypropylene, the wool strip has the characteristics of being light, soft, elastic, and soft. It can quickly restore its original shape after compression, maintain the sealing effect, and can prevent insects, mosquitoes, etc. from entering the room. It is not easy to deform, has a long life, and has a high cost performance.

[0028] The sealing hair 2 and the base plate 1 can be connected as one by a fixing method such as ultrasonic welding, hot melt process, etc., which is not particularly limited in this embodiment. However, it is particularly advantageous and simple that the sealing hair 2 is connected to the base plate 1 by a hot melt process. Specifically, the base plate 1 is placed tightly on the heating tool, and the installation surface of the base plate 1 is heated by the heating tool until it softens. After removing the heating tool, the sealing hair 2 is placed on the installation surface of the base plate 1, and a certain pressure is maintained to cool the base plate 1, so that the base plate 1 and the sealing hair 2 are connected as one. The hot melt process can be used to very quickly install the sealing hair 2 on the base plate 1. The connection strength between the base plate 1 and the sealing hair 2 is very high. Compared with other connection methods, the cost is lower, and it is an economical and effective connection method.

[0029] The base plate 1 includes a plate body 11 and a buffer pad 12 connected to the plate body 11 .

[0030] The plate body 11 is generally in a strip-shaped structure and has an installation surface for attaching the sealing hairs 2. For ease of description, the length direction of the plate body 11 is defined as the transverse direction, and the width direction of the plate body 11 is defined as the longitudinal direction. A plurality of sealing hairs 2 are arranged in rows along the transverse and longitudinal directions of the plate body 11.

[0031] At least one longitudinal side of the plate body 11 has the buffer pad 12. The buffer pad 12 is elastic and partially protrudes from the plate body 11. When the wool strip is inserted into the T-slot of the door and window, the buffer pad 12 is elastically deformed by pressure and fills the gap between the plate body 11 and the T-slot, forming interference between the wool strip and the door and window, avoiding the problem of overall movement of the wool strip due to mismatch of the wool strip size, improving the compatibility of the wool strip, and making the wool strip adapt to more scenes.

[0032] The plate body 11 and the buffer pad 12 may be connected by bonding or integral molding, which is not particularly limited in the present embodiment. However, it is particularly advantageous and simple that the plate body 11 and the buffer pad 12 are integrally molded, so that the production process of the base plate 1 is generally more efficient, which can save labor and time costs, and the overall strength of the base plate 1 is high.

[0033] The buffer pad 12 in this embodiment needs to have a certain degree of elasticity. Under the condition that the plate body 11 and the buffer pad 12 are integrally formed, the material of the plate body 11 and the buffer pad 12 can be selected from high molecular polymers such as rubber, for example, the material is selected from polypropylene, which has sufficient elasticity and toughness while ensuring strength.

[0034] In some embodiments, the two opposite sides of the buffer pad 12 (the two sides in the height direction of the buffer pad 12) both protrude from the plate body 11, and the force distribution when the buffer pad 12 is under pressure is more uniform. This embodiment does not specifically limit the shape of the buffer pad 12. For example, the transverse cross-section of the buffer pad 12 is corrugated, and the transverse cross-section refers to a cross-section parallel to the length direction of the plate body 11.

[0035] The buffer pad 12 includes arc segments 122 and straight segments 121 that are alternately connected. The arc segments 122 form wave crests and wave troughs. The arc segments 122 and the arc segments 122 are not directly connected to each other, and the straight segments 121 and the straight segments 121 are not directly connected to each other. The shapes and sizes of the multiple arc segments 122 can be the same or different, and this embodiment does not make any special restrictions, but the arc segments 122 are basically the same, so that the buffer pad 12 is in uniform contact with the groove wall of the T-slot and the forces are balanced. The length dimensions of the multiple straight segments 121 are consistent with each other, and the thickness dimensions of the multiple straight segments 121 are also consistent with each other, so that the longitudinal section of the buffer pad 12 presents a wave shape with uniform dimensions, that is, a uniform buffer pad 12 structure is provided on the plate body 11, and the dimensions of the buffer pad 12 protruding outward are consistent. When the wool strip is inserted into the T-slot of the door and window, the buffer pad 12 is uniformly stressed as a whole.

[0036] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
