Description

Technical Field

[0001] The utility model relates to the technical field of invisible manhole covers, in particular to an anti-deformation type invisible manhole cover. Background Art

[0002] Invisible manhole covers usually refer to manhole covers designed for underground facilities (such as drainage systems, cable channels, etc.), which are characterized by not being easily noticed by pedestrians or vehicles to improve urban aesthetics and safety. This kind of manhole cover may adopt materials and colors similar to the surrounding ground, or adopt special designs to make it visually integrated with the ground.

[0003] At present, when the existing invisible manhole cover is subjected to stress from the top for a long time, it will cause the middle of the invisible manhole cover to be concave and deform and damage, shortening the service life of the cover body and affecting the flatness between the invisible manhole cover and the ground. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-deformation invisible manhole cover to solve the problems raised in the above background technology.

[0006] Furthermore, two reinforcement frames are symmetrically arranged at the lower ends of the partition, respectively integrated with the reinforcement rib array on the same side.

[0010] Furthermore, the transverse cross-sections of the joints between the reinforcing ribs and the reinforcing frame, the first annular reinforcing frame, the second annular reinforcing frame and the connecting block are all arranged in an arc shape.

[0011] Furthermore, the height of the longitudinal section of the reinforcing rib is gradually decreased from the inner wall of the inner frame to the intersection of the plurality of reinforcing ribs.

[0012] Furthermore, a connecting column is integrally provided at the bottom end of the connecting block located at the bottom end of the partition, and the height of the longitudinal section of the reinforcing rib located between the connecting column and the inner wall of the inner frame is gradually decreased from the inner wall of the inner frame and the outer wall of the connecting column to the second annular reinforcement frame.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-4As shown, the utility model discloses an anti-deformation invisible manhole cover, comprising: an outer frame 1 and an inner frame 2 whose outer wall is fitted and slidably connected to the inner wall of the outer frame 1, a partition 21 is fixedly arranged in the middle of the inner wall of the inner frame 2, and two reinforcing rib arrays 22 are symmetrically and fixedly arranged at the upper and lower ends of the partition 21, the reinforcing rib array 22 is composed of a plurality of reinforcing ribs that are equally spaced and cross-arranged, the intersection points of the plurality of reinforcing ribs are aligned with the center points of the partition 21, the ends of the reinforcing ribs are fixedly arranged with the inner wall of the inner frame 2, and the ends of the reinforcing ribs extend along the inner wall of the inner frame 2 to the side away from the partition 21.

[0020] Based on the above structure, Figure 1-3 As shown, when the top of the inner frame 2 is subjected to stress, the multiple reinforcing ribs of the reinforcing rib array 22 are evenly spaced and cross-arranged, so that the stress on the inner frame 2 can be evenly distributed in the structure, reducing deformation or damage caused by excessive local stress.

[0021] Further, such as Figure 1-3 As shown, two reinforcing frames 23 are symmetrically arranged at the lower two ends of the partition 21, which are respectively integrated with the reinforcing rib array 22 on the same side. The reinforcing frame 23 is fixed along the inner wall of the inner frame 2 and is fixedly connected to the partition 21. The reinforcing frame 23 is integrally arranged with the reinforcing rib array 22, which can provide additional support points and further enhance the strength and stability of the entire structure. At the same time, the design that the reinforcing frame 23 is fixed along the inner wall of the inner frame 2 and is fixedly connected to the partition 21 helps to improve the overall rigidity of the inner frame 2 structure and reduce deformation when subjected to force.

[0022] Further, such as Figure 1-3 As shown, a first annular reinforcement frame 24 is integrally provided in the reinforcement frame 23. The first annular reinforcement frame 24 is integrally provided with the reinforcement rib array 22 and is fixedly connected to the partition 21. The provision of the annular reinforcement frame 24 helps to disperse the stress on the reinforcement rib array 22 and reduce stress concentration, thereby extending the service life of the structure.

[0023] Further, such as Figure 1-3 As shown, a second annular reinforcement frame 25 is provided in the first annular reinforcement frame 24 and is integrally provided with the reinforcement rib array 22 . The second annular reinforcement frame 25 is fixedly connected to the partition 21 . The provision of the second annular reinforcement frame 25 further increases the effect of dispersing the stress on the reinforcement rib array 22 .

[0024] Further, such as Figure 1-3As shown, a connecting block 26 with a circular transverse cross-section is integrally provided at the intersection of multiple reinforcing ribs. The connecting block 26 is fixedly connected to the partition 21. By providing a connecting block at the intersection of multiple reinforcing ribs, the various reinforcing ribs can be effectively connected into a whole, thereby improving the integrity and stability of the structure. This design helps to disperse and transfer loads, reduce stress concentration, and improve the bearing capacity of the structure. At the same time, the design of the circular connecting block can optimize stress distribution, reduce stress concentration at the connection, thereby improving the strength and durability of the connection.

[0025] Further, such as Figure 2 and 3 As shown, the transverse cross-sections of the joints between the reinforcing ribs and the reinforcing frame 23, the first annular reinforcing frame 24, the second annular reinforcing frame 25 and the connecting block 26 are all arc-shaped. The arc-shaped design can make the stress more evenly distributed at the joints, reduce stress concentration, and avoid fatigue damage or fracture caused by stress concentration.

[0026] Further, such as Figure 4 As shown, the height of the longitudinal section of the reinforcing rib is gradually reduced from the inner wall of the inner frame 2 to the intersection of multiple reinforcing ribs. Near the inner wall of the inner frame, the height of the reinforcing rib is relatively large, which can provide stronger support and stability. At the intersection of the reinforcing ribs, the height gradually decreases, which helps to disperse the stress at the intersection and prevent damage caused by stress concentration.

[0027] Further, such as Figure 4 As shown, a connecting column 261 is integrally provided at the bottom end of the connecting block 26 located at the bottom end of the partition 21, and the height of the longitudinal section of the reinforcing rib between the connecting column 261 and the inner wall of the inner frame 2 is gradually decreased from the inner wall of the inner frame 2 and the outer wall of the connecting column 261 to the second annular reinforcement frame 25. By setting the height of the longitudinal section of the reinforcing rib at the outer wall of the connecting column 261 and the inner wall of the inner frame 2 to the maximum, the support and rigidity at the outer wall of the connecting column 261 and the inner wall of the inner frame 2 can be increased, thereby preventing deformation or damage at these key locations.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
