Description

Technical Field

[0001] This utility model belongs to the field of equipment sealing technology, specifically relating to a sealing strip with an e-type structure. Background Technology

[0002] In existing technologies, sealing strips are widely used in various equipment and devices to provide a sealing effect, preventing external media (such as gases, liquids, or solid particles) from entering the equipment, thereby protecting the normal operation of the equipment and extending its service life. However, traditional sealing strip designs often have some defects that affect their sealing effect and service life.

[0003] On the one hand, traditional sealing strips typically employ relatively simple structures, such as straight or curved shapes. These structures are prone to deformation under external forces and are difficult to quickly return to their original shape, resulting in unsatisfactory sealing performance. Especially during long-term use, the shape and performance of the sealing strip are prone to changes, reducing its sealing performance and service life.

[0004] On the other hand, traditional sealing strips often suffer from unstable clamping, slippage, or displacement when holding equipment stiffeners. This not only affects the sealing effect but may also lead to equipment malfunction or damage. Furthermore, traditional sealing strips present certain difficulties in installation and maintenance, such as inconvenient installation and high maintenance costs. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0026] This utility model embodiment provides a sealing strip with an e-type structure, such as Figure 1 , 2 As shown, it includes:

[0027] The outer surface 11 of the e-shaped head 1 is a compression sealing surface used to withstand external forces;

[0028] The inner surface 21 of the e-shaped tail 2 is connected to the inner surface 12 of the e-shaped head 1 to form a slot structure 22 for clamping the equipment stiffener 3.

[0029] This invention achieves a sealing effect by using the outer surface 11 of the e-shaped head 1 when subjected to compressive force. After the external compressive force is removed, it can quickly and naturally rebound to its original shape, ensuring that the sealing strip can maintain its original shape and sealing effect during long-term use and extending its service life. Furthermore, it achieves clamping of the equipment stiffener 3 by combining with the e-shaped tail 2.

[0030] Specifically, the outer surface 11 of the e-shaped head 1 is a semi-circular arc structure. When subjected to external force, the semi-circular arc structure can evenly distribute pressure, reduce stress concentration, thereby improving the stability of the structure and increasing the contact area between the e-shaped head 1 and the contact surface, which helps to improve the sealing effect.

[0031] Taking the door frame as the object to which external extrusion force is applied, the semi-circular arc structure gradually transitions from line contact to surface contact during the extrusion and sealing process with the door frame. The reaction force on the door frame increases from small to large, making the force more uniform when the door frame is closed. When the door frame is opened, the door frame and the outer surface 11 of the e-shaped head 1 gradually transition from surface contact to line contact, effectively avoiding the vacuum adsorption effect generated between the outer surface 11 of the e-shaped head 1 and the surface of the door frame.

[0032] Furthermore, the interior of the e-shaped head 1 is a hollow structure. The hollow structure reduces the amount of material used, and when combined with the semi-circular arc structure, it can still form an effective support structure, increasing the overall strength and stability of the e-shaped head 1.

[0033] Furthermore, the hollow structure is arched.

[0034] The arched hollow structure does not directly bear external pressure at the top, but converts the external pressure into an outward thrust along the arch surface, which is borne by the arch support legs, thereby enhancing the sealing stability of the outer surface.

[0035] The arched hollow structure of the e-shaped head 1 is easily compressed and sealed when squeezed by the external force of the door frame. When the door frame is separated from the e-shaped head 1, the arched hollow structure is more likely to spring open and return to its original shape, while saving materials and reducing the weight of the overall structure.

[0036] Specifically, the inner surface 21 of the e-shaped tail 2 and the inner surface 12 of the e-shaped head 1 form a slot structure with an angle of α in the natural state.

[0037] The slot structure allows the e-shaped tail 2 to be naturally clamped onto the equipment stiffener 3, forming a self-locking effect. This helps prevent the sealing strip from loosening or falling off during use, thereby enhancing the stability of the structure.

[0038] Because the slot structure forms an included angle α in its natural state, it can provide better support and fixation when there are external forces such as vibration and impact, reducing the deformation or displacement of the sealing strip caused by external forces.

[0039] At the same time, the natural clamping state of the slot structure can reduce the problem of poor sealing caused by excessive gaps.

[0040] Furthermore, the inner surface 21 of the e-shaped tail 2 and the inner surface 12 of the e-shaped head 1 are both planar. On the one hand, this facilitates processing; on the other hand, the planar inner surface allows the clamping force to be more evenly distributed across the entire contact surface when the sealing strip clamps the equipment stiffener 3, avoiding local stress concentration and improving the stability and reliability of clamping.

[0041] Furthermore, the included angle α satisfies 5°≦α≦15°.

[0042] An appropriate groove structure can be formed between the e-shaped tail 2 and the e-shaped head 1 through the included angle α, which can more effectively clamp the equipment stiffener 3 and ensure the stability and firmness of the sealing strip on the equipment.

[0043] By controlling the size of the included angle α, it is ensured that the sealing strip will not generate excessive stress concentration when clamping the equipment stiffener 3, thus avoiding damage or deformation of the sealing strip due to excessive stress. It also helps to form a tighter fit between the sealing strip and the equipment stiffener, thereby improving the sealing performance.

[0044] Furthermore, the inner surface 21 of the e-shaped tail 2 is provided with an elastic material layer.

[0045] The sealing effect between the sealing strip and the equipment stiffener 3 is enhanced by an elastic material layer. When the equipment stiffener 3 comes into contact with the sealing strip, the elastic material layer provides better adaptability and compressibility, thereby ensuring a tight fit between the two and reducing the possibility of leakage.

[0046] The outer surface 23 of the e-shaped tail 2 is provided with anti-slip texture or raised structure.

[0047] By setting anti-slip textures or raised structures, the friction between the outer surface 23 of the e-shaped tail 2 and the equipment housing 4 can be increased, thereby preventing the sealing strip from failing due to sliding or displacement during use.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
