High sealing performance door frame profile for engineering machinery

Abstract

This utility model relates to the field of door frame profiles, and more particularly to a high-sealing door frame profile for engineering machinery, comprising a tubular structure formed by multiple bends, including a mounting horizontal plate, a mounting vertical plate, an arc-shaped plate, and a guide plate. The tubular thickness is 2mm, and each bend is designed with specific angles such as 90° and 180° and radii such as 3mm and 20mm to form a tightly fitting sealing surface. The arc-shaped plate and semi-circular bends enable the tube wall to have controllable elastic deformation capability. When the door panel is opened and closed, the guide plate undergoes a slight deformation under the thrust and then quickly rebounds, balancing smooth opening and closing with a tight seal. The mounting horizontal plate and fastening plate are quickly installed using fasteners. The mounting horizontal plate fits snugly against the door panel, and the guide plate overlaps with the side of the door panel, forming multiple seals. This profile solves the problems of poor sealing, insufficient rigidity, and complex installation of traditional structures, and is suitable for high-protection scenarios in the field of engineering machinery.

Description

Technical Field

[0001] This utility model relates to the field of door frame profiles, and in particular to a high-sealing door frame profile for engineering machinery. Background Technology

[0002] In the field of construction machinery, the sealing performance and structural reliability of door frame profiles directly affect the protective performance and service life of the equipment. In existing technologies, traditional door frame profiles often employ simple bending structures, resulting in insufficient fit between the sealing strip and the door panel, making them prone to sealing failure due to deformation under stress. Furthermore, during the opening and closing process, insufficient rigidity or poor resilience of the profiles often leads to door jamming or incomplete closure, especially under frequent opening and closing conditions, which accelerates the wear of the sealing structure. While some designs increase strength by increasing material thickness, this sacrifices lightweight requirements and makes it difficult to balance installation convenience with dynamic deformation adaptability.

[0003] Therefore, achieving both high sealing performance and excellent resilience and structural stability in door frame profiles is a challenging technical problem in the industry. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a high-sealing door frame profile for engineering machinery. This door frame profile solves the problems of poor sealing, insufficient rigidity, and complex installation of traditional structures through flexible design of thickness, structure, and bends. Specifically, it is achieved through the following technical solutions.

[0005] This utility model relates to a high-sealing door frame profile for engineering machinery, comprising a tube body and a closed tube cavity formed by bending the tube body. The tube body is composed of multiple plates connected end to end in sequence, including a mounting horizontal plate, a mounting vertical plate, an arc plate, a guide plate, a connecting plate, a contact horizontal plate, a first fastening plate, and a second fastening plate.

[0006] The first end of the mounting horizontal plate is bent and extended to form a mounting vertical plate. The end of the mounting vertical plate away from the mounting horizontal plate is bent and extended to form an arc-shaped plate. The end of the arc-shaped plate away from the mounting vertical plate is bent and extended to form a guide plate. The end of the guide plate away from the arc-shaped plate is bent and extended to form a connecting plate. The end of the connecting plate away from the guide plate is bent and extended to form a contact horizontal plate. The end of the contact horizontal plate away from the connecting plate is bent and extended to form a first fastening plate. The end of the first fastening plate away from the contact horizontal plate is bent and extended to form a second fastening plate. The end of the second fastening plate away from the first fastening plate is bent and extended to form the mounting horizontal plate.

[0007] The tube body connects the various plates through multiple bends. The mounting plate, arc plate, second bend, guide plate, third bend, connecting plate, and semi-circular bend form a cavity, which facilitates the opening and closing of the door panel. The tight fit of the contact plate, fourth bend, first fastening plate, second fastening plate, sixth bend, and mounting plate achieves a seal.

[0008] Preferably, the mounting horizontal plate and the mounting vertical plate are connected by a first bend, the angle of the first bend is 90°, and its outer surface radius is 3mm.

[0009] Preferably, the outer surface radius of the arc-shaped plate is 20mm and it is tangential to the mounting plate; the arc-shaped plate and the guide plate are connected by a second bend, the outer surface radius of which is 4mm.

[0010] Preferably, the guide plate and the connecting plate are connected by a third bend, the angle of which is 86° and the outer surface radius is 4mm.

[0011] Preferably, the connecting plate and the contact cross plate are connected by a semi-circular bend, the angle of which is 180°.

[0012] Preferably, the contact plate is connected to the first fastening plate via a fourth bend, the angle of which is 90°; the first fastening plate is connected to the second fastening plate via a fifth bend, the angle of which is 180°.

[0013] Preferably, the second fastening plate and the mounting cross plate are connected by a sixth bend, the angle of which is 90°.

[0014] Preferably, the distance from the intersection of the outer surface of the guide plate and the outer surface of the arc plate to the Y-direction vertex of the fifth bend in the negative Y direction is 41.6 mm; the vertical distance from the vertex of the fifth bend in the negative Y direction to the outer surface of the mounting plate is 10.2 mm.

[0015] Preferably, the vertical distance between the outer surface of the contact plate and the outer surface of the connecting plate is 4.8 mm; the vertical distance between the outer surface of the first fastening plate and the outer surface of the mounting plate is 43 mm.

[0016] Preferably, the vertical distance from the intersection of the outer surface of the guide plate and the outer surface of the connecting plate to the outer surface of the first fastening plate is 28mm; the vertical distance from the vertex of the semi-circular bend outer surface in the X direction to the outer surface of the first fastening plate is 37mm.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. By tightly fitting the contact plate to the door panel and combining the overlapping structure of the guide plate and the side of the door panel, multiple sealing surfaces are formed, effectively preventing moisture and dust from seeping in and improving the overall sealing performance.

[0019] 2. Through the combination design of arc plate and semi-circular bend, the pipe wall produces controllable micro-deformation when the door is opened and closed. At the same time, the material elasticity allows for rapid rebound, which reduces opening and closing resistance and ensures a tight fit of the sealing surface after closure.

[0020] 3. The 2mm thick tube body and multi-section bending design reduce redundant materials while ensuring structural rigidity, achieving a balance between lightweight and high strength.

[0021] 4. The installation process is simplified by using a combination of mounting plates, fastening plates and fixing parts. The radius and spacing parameters of each bend are precisely matched to common door panel sizes, improving versatility and adaptability. Attached Figure Description

[0029] This utility model provides a high-sealing door frame profile for engineering machinery. See [link / reference]. Figure 1 , Figure 2 The high-sealing door frame profile for engineering machinery includes a tube body, which is bent to form a cavity. The tube body is 2mm thick and includes a mounting horizontal plate 101, a mounting vertical plate 103, an arc plate 104, a guide plate 106, a connecting plate 108, a contact horizontal plate 110, a first fastening plate 112, and a second fastening plate 114 connected end to end in sequence.

[0030] The first end of the mounting horizontal plate 101 is bent counterclockwise to form a mounting vertical plate 103. The mounting horizontal plate 101 and the mounting vertical plate 103 are bent to form a first bend 102 with an angle of 90° and a radius of 3mm on the outer surface of the first bend 102.

[0031] The end of the arc-shaped plate 104 away from the mounting plate 103 is bent counterclockwise to form a guide plate 106. The arc-shaped plate 104 and the guide plate 106 are bent to form a second bend 105, and the radius of the outer surface of the second bend 105 is 4mm. The end of the guide plate 106 away from the second bend 105 is bent counterclockwise to form a connecting plate 108. The connecting plate 108 and the guide plate 106 are bent to form a third bend 107, the angle of the third bend 107 is 86°, and the radius of the outer surface of the third bend 107 is 4mm.

[0032] The end of the connecting plate 108 furthest from the third bend 107 is bent clockwise to form a contact plate 110. The connecting plate 108 and the contact plate 110 are bent to form a semi-circular bend 109 with an angle of 180°. The end of the contact plate 110 furthest from the semi-circular bend 109 is bent counterclockwise to form a first fastening plate 112. The contact plate 110 and the first fastening plate 112 are bent to form a fourth bend 111 with an angle of 90°. The end of plate 112 away from the fourth bend 111 is bent counterclockwise to form a second fastening plate 114. The second fastening plate 114 and the first fastening plate 112 are bent to form a fifth bend 113, and the angle of the fifth bend 113 is 180°. The end of the second fastening plate 114 away from the fifth bend 113 is bent clockwise to form a mounting horizontal plate 101. The mounting horizontal plate 101 and the second fastening plate 114 are bent to form a sixth bend 115, and the angle of the sixth bend 115 is 90°.

[0033] The inner surfaces of the contact plate 110, the fourth bend 111, and the first fastening plate 112 are in close contact with the inner surfaces of the second fastening plate 114, the sixth bend 115, and the mounting plate 101.

[0034] The cavity is formed by mounting plate 103, arc plate 104, second bend 105, guide plate 106, third bend 107, connecting plate 108, and semi-circular bend 109.

[0035] The distance between the intersection of the outer surface of the guide plate 106 and the outer surface of the arc plate 104 and the vertex of the fifth bend 113 in the negative Y direction is 41.6 mm; the vertical distance between the vertex of the fifth bend 113 in the negative Y direction and the outer surface of the mounting plate 101 is 10.2 mm; and the vertical distance between the outer surface of the contact plate 110 and the outer surface of the connecting plate 108 is 4.8 mm.

[0036] The vertical distance between the outer surface of the first fastening plate 112 and the outer surface of the mounting plate 103 is 43mm; the vertical distance between the vertex of the outer surface of the semi-circular bend 109 in the X direction and the outer surface of the first fastening plate 112 is 37mm; and the vertical distance between the intersection of the outer surfaces of the guide plate 106 and the outer surface of the connecting plate 108 and the outer surface of the first fastening plate 112 is 28mm.

The outer surface of the contact plate 110 is in contact with the door panel, and the outer surface of the guide plate 106 overlaps with the side of the door panel, thereby achieving a sealing effect after the door panel is closed.

[0039] During the rotation and closing of the door panel, the edge of the door panel overlaps with the outer surface of the guide plate 106 first, and applies a thrust along the X direction to the guide plate 106, causing slight deformation of the tube wall formed by the connection of the mounting plate 103, the arc plate 104, the second bend 105, the guide plate 106, the third bend 107, the connecting plate 108, and the semi-circular bend 109, which facilitates the closing of the door panel until the side of the door panel is in contact with the outer surface of the contact plate 110.

[0040] Conversely, when the door panel is opened from the closed state, the sides and edges of the door panel successively overlap with the outer surface of the third bend 107, causing the aforementioned pipe wall to undergo slight deformation again, which facilitates the opening of the door panel.

[0041] In the above process, the arc-shaped plate 104 and the semi-circular bend 109 make the pipe wall formed by the connection of the mounting plate 103, the arc-shaped plate 104, the second bend 105, the guide plate 106, the third bend 107, the connecting plate 108, and the semi-circular bend 109 have the characteristic of easy rebound. On the one hand, it is easy to avoid the edge of the door panel and facilitate the opening and closing process of the door panel. On the other hand, it is easy to achieve the sealing effect after the door panel is closed.

[0042] The embodiments described above are not exhaustive, nor do they limit the scope of the present invention to the specific embodiments described herein. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to effectively utilize the present invention and its modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
