[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model discloses a steel cover with a hinge rod, which is provided with two hinge rod assemblies at the bottom of the rib plate, and the two hinge rod assemblies are symmetrical to each other. The two hinge rod assemblies make the steel cover run smoothly and more stably, with less running resistance and flexible operation during operation, and will not have intermittent jamming due to friction between the cover plates. In order to facilitate the connection between the hinge rod assembly and the steel cover body, a plurality of connecting rods nested in sequence are provided in the hinge rod assembly, which connect the connecting rods to the rib plate, so that the movement of the rib plate drives the movement of the hinge rod assembly.

[0017] 2. The hinge rod assembly disclosed in the utility model is composed of two short rod assemblies and multiple long rod assemblies, and has a simple structure. In order to facilitate the connection between the hinge rod assembly and the rib plate, short rod assemblies are selected at both ends of the hinge rod assembly, and the number of long rod assemblies is appropriately selected in the middle of the two short rod assemblies according to the stretching length of the steel cover. The stretching and compression of the hinge rod assembly is reasonably selected through the stretching and compression of the machine tool.

[0018] 3. The upper short rod and the lower short rod in the short rod assembly of the utility model are parallel to each other, the middle short rod and the upper short rod are cross-connected, the upper long rod and the lower long rod in the long rod assembly are parallel to each other, the middle long rod and the upper long rod are cross-connected, and finally they are connected to each other to form an "8"-shaped hinge structure.

[0019] 4. The utility model embeds a bearing in the through hole. The bearing used in the utility model is an oil-free bearing. This bearing has a self-lubricating effect and requires little or no maintenance during use. It not only reduces the number of maintenance times, but also can greatly reduce operating resistance, reduce vibration, reduce noise, and extend service life.

[0020] 5. In the utility model, one end of the bearing is flanged and fits with the upper short rod or the upper long rod. This flanged structure can be used as a gasket between the nut and the upper short rod or the upper long rod, which not only increases the contact area, prevents loosening, and protects the screws, but more importantly, can greatly reduce the difficulty of installation, save installation time, and improve installation efficiency.

[0021] 6. In the utility model, the first rod in the first screw is matched with the bearing in the through hole, and the second rod in the second screw is matched with the threaded hole, so that the first rod in the first screw and the second rod in the second screw can be used as the rotation axis, so that the first screw and the second screw not only play a connecting role, but also play a rotating role, which greatly simplifies the structure of the hinge rod assembly.

[0022] 7. In order to more firmly connect the connecting rod to the short rod assembly or to the long rod assembly, the utility model sets the length of the first screw to be longer than the length of the second screw, so that the first screw can pass through various components of the hinge rod assembly.

The utility model sets two hinge rod assemblies 3 at the bottom of the rib plate 2, and the two hinge rod assemblies 3 are symmetrical to each other. Through the two hinge rod assemblies 3, the steel cover runs smoothly and more stably during operation, with small running resistance and flexible operation, and will not be intermittently stuck due to the friction between the cover plates 1. In order to facilitate the connection between the hinge rod assembly 3 and the steel cover body, a plurality of connecting rods 33 nested in sequence are set in the hinge rod assembly 3, and the connecting rods 33 are connected to the rib plate 2, so that the movement of the rib plate 2 drives the movement of the hinge rod assembly 3.

[0035] In some embodiments, a nested assembly method in the prior art is adopted to form a steel cover body with a multi-level structure by nesting and assembling cover panels 1 of different sizes; and the hinge rod assembly 3 arranged at the bottom of the steel cover body mainly utilizes the relative sliding movement between the cover panels 1 during the opening and closing movement of the steel cover body to drive the bottom hinge rod assembly 3 to move, so that the steel cover body is more stable and more flexible in operation during the movement through the cooperation of the hinge rod assembly 3.

[0047] Furthermore, the length of the first screw 4 is greater than that of the second screw 5. In order to more firmly connect the connecting rod 33 to the short rod assembly 31 or to more firmly connect the connecting rod 33 to the long rod assembly 32, the length of the first screw 4 is set to be longer than that of the second screw 5, so that the first screw 4 can pass through various parts of the hinge rod assembly 3.
