Description
The technical field is as follows:
the utility model relates to the technical field of cover plates of ditches, in particular to a cast iron rainwater grate; can be widely used in different places such as ditches (wells) of municipal roads, garden facilities, residential districts, schools, stadiums and the like.
Background art:
the existing rainwater grate has simple structure, generally adopts the ditch cover to be directly clamped on the ditch cover body, has simple construction, inflexible switching in the using process, makes sound when vehicles and pedestrians pass through, has untight combination of the ditch cover and the ditch cover body, can generate phenomena of jumping, lifting, sounding, displacement and the like, is easy to lose and has poor safety.
The utility model has the following contents:
the utility model aims to overcome the defects of the prior art and provide a cast iron rainwater grate.
The utility model provides a technical scheme is: the cast iron rainwater grate consists of a gutter cover body and a gutter cover and is characterized in that two outer hinge seats are arranged on the gutter cover; the groove cover body is provided with two inner spring seats, a spring is arranged between the two inner spring seats, a chain shaft penetrates through the two inner spring seats and the spring in the middle, two ends of the chain shaft are respectively inserted into two outer hinge seats adjacent to the outer sides of the two inner spring seats, and a one-way spring hinge connection is formed between the groove cover body and the groove cover; the groove cover is provided with a latch lock and a key hole, after the latch lock is clamped with a corresponding groove on the groove cover body, the groove cover is locked with the groove cover body, a key is inserted into the key hole, the groove cover can be bounced and opened from the groove cover body through rotation, and the angle between the latch lock and the groove cover body is an oblique angle of 100 degrees and 105 degrees after the groove cover is opened; the groove cover body is provided with a special-shaped groove, and a special-shaped rubber ring is embedded in the special-shaped groove.
The utility model has the advantages that: 1. because the rainwater grate has large carrying capacity, the connecting ditch is connected by the one-way spring hinge, and when the ditch cover is opened, the oblique angle of 105 degrees is automatically opened under the action of the one-way spring hinge, so that the rainwater grate is convenient to operate, labor-saving to close, time-saving, efficiency-improving and convenient to open; 2. the spring lock structure is adopted, the lock is locked when being closed, the anti-theft function is realized, and the lock is opened by matching with a key, so that the safety and the reliability are realized; 3. the special-shaped rubber ring is adopted for sealing, the shock absorption effect is good under the action of external force, and no sound is generated when vehicles and pedestrians pass through the special-shaped rubber ring, so that the special-shaped rubber ring meets the requirement of environmental protection; 4. the groove cover and the groove cover body are tightly combined, the phenomena of jumping, lifting, sounding, displacement and the like can not be generated, and the groove cover is noiseless, safe and reliable; 5. the drainage device has the advantages of attractive appearance, optimal drainage, multiple specifications, low cost, convenient operation, labor saving and labor saving, and improvement on economic benefit.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure: the groove cover comprises a groove cover body 1, a groove cover 2, an outer hinge seat 3, a latch lock 4, a special-shaped rubber ring 5, a special-shaped groove 6, a chain shaft 7, a spring 8, an inner spring seat 9 and a key hole 10.
The specific implementation mode is as follows:
for a better understanding and practice, the following detailed description of the embodiments is given in conjunction with the accompanying drawings; the illustrated embodiments are provided only for explaining the present invention and not for limiting the scope of the present invention.
As shown in fig. 1, the cast iron rainwater grate is made of cast iron, has various types and can be selected, is suitable for different span loads and requirements, and can select different specifications and types according to different use sites; the cast iron rain grate is generally adopted, and the specification is 300 cm multiplied by 500 cm, 400 cm multiplied by 400 cm, 400 cm multiplied by 500 cm, 400 cm multiplied by 600 cm and 500 cm multiplied by 500 cm;
the cast iron rainwater grate consists of a ditch cover body 1 and a ditch cover 2, and two outer hinge seats 3 are welded on the ditch cover 2; two inner spring seats 9 are welded on the trench cover body 1, a spring 8 is arranged between the two inner spring seats 9, the chain shaft 7 passes through the two inner spring seats 9 and the middle spring 8, two ends of the chain shaft are respectively inserted into the two outer hinge seats 3 which are adjacent to the outer sides of the two inner spring seats 9, and a one-way spring hinge connection is formed between the trench cover body 1 and the trench cover 2, namely the trench cover 2 can only be opened in one way; the spring lock 4 and the key hole 10 are arranged on the groove cover 2, after the spring lock 4 is clamped with the corresponding groove on the groove cover body 1, the groove cover 2 and the groove cover body 1 are locked, a key is inserted into the key hole 10, the groove cover 2 can be bounced up and opened from the groove cover body 1 through rotation, and the angle between the two after the opening is an oblique angle of 100 degrees and 105 degrees; a special-shaped groove 6 is arranged on the trench cover body 1, and a special-shaped rubber ring 5 is embedded in the special-shaped groove 6.
