Description

Technical Field

[0001] The utility model relates to the technical field of casting parts, and more specifically, it relates to a combined bracket casting part. Background Art

[0002] Urban roads generally have rainwater grates, and the rainwater grates are installed on the road surface through brackets. The brackets are fixedly connected to the road surface to provide support for the rainwater grates.

[0003] In heavy rain weather, after encountering heavy rainfall, water accumulates on the road surface. In order to reduce the obstruction to traffic caused by the water accumulation on the road surface, drainage workers will take the method of uncovering the rainwater grates to accelerate the rainwater drainage speed and help the accumulated water drain into the drainage outlet. This approach is one of the most direct and effective methods.

[0004] However, after the rainwater grate is uncovered, it cannot block the drainage outlet, and the accumulated water affects the line of sight, making it easy for surrounding pedestrians and vehicles to fall into the drainage outlet.

[0005] This application provides another technical solution to solve this technical problem. Content of the Utility Model

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a combined bracket casting part.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions:

[0008] A combined bracket casting part includes a main frame and a sub-frame. The sub-frame is slidably connected to the main frame through a connecting rod. The main frame is provided with a through hole, and a support column is slidably arranged in the through hole. The support column is connected to the connecting rod. A retaining ring is formed at the opening edge of the through hole, and a limiting member for restricting the sliding of the support column is arranged between the retaining ring and the support column.

[0009] The utility model is further arranged as follows: The support column is rotatably connected to the through hole, and the support column and the connecting rod rotate relative to each other. The retaining ring is provided with a guiding channel. The limiting member includes a supporting convex located in the guiding channel. The guiding channel sequentially includes a first sliding channel, a first rotating channel, a second sliding channel, and a second rotating channel. The length directions of the first sliding channel and the second sliding channel are the same as the length direction of the support column, and the length directions of the first rotating channel and the second rotating channel are the same as the circumferential direction of the support column.

[0010] The utility model is further arranged as follows: A plurality of limiting teeth are formed in the second rotating channel, and a gap for the supporting convex to slide into is formed between adjacent two limiting teeth.

[0011] The utility model is further arranged as follows: A reflective strip is fixedly arranged on the outer side of the support column.

[0012] The utility model is further arranged such that: a drainage groove is formed inside the support column, and a drainage port communicating with the drainage groove is formed in the side wall of the support column.

[0013] The utility model is further arranged such that: a handle is fixedly installed on the support column.

[0014] In summary, the utility model has the following beneficial effects:

[0015] When there is water accumulation on the road surface, the auxiliary frame can be raised by operating the support column, so that the water can directly enter the sewer through the main frame, accelerating drainage. At the same time, the rising height of the support column is higher than that of the auxiliary frame, and by using the reflection of the reflective strip, pedestrians and vehicles around are reminded that accelerated drainage is being carried out here, reducing the risk of pedestrians and vehicles falling into the sewer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] As Figure 1As shown, the present application provides a combined bracket casting, which includes a main bracket 1 and a sub-bracket 2. A connecting rod 3 is formed on the sub-bracket 2, and a connecting groove for the connecting rod 3 to slide into is formed on the main bracket 1. By the cooperation of the connecting rod 3 and the connecting groove, relative sliding can be carried out between the main bracket 1 and the sub-bracket 2. The sub-bracket 2 is used to install a rain grate. In the initial state, the sub-bracket 2 abuts against the main bracket 1 due to gravity, so that the rain grate blocks the opening of the sewer. When it rains, rainwater will pass through the rain grate and enter the sewer.

[0023] As Figure 1 and Figure 2 shown, the main bracket 1 is provided with a through hole 4, and a retaining ring 16 is formed at the opening edge of the through hole 4. In this embodiment, two through holes 4 are symmetrically arranged. A support column 5 is slidably arranged in the through hole 4, and the support column 5 is rotatably connected to the through hole 4. The connecting rod 3 forms a limiting groove, and a ring protrusion located in the limiting groove is formed on the support column 5. The ring protrusion can slide in the limiting groove. When the support column 5 slides in the through hole 4, the support column 5 can drive the connecting rod 3, the sub-bracket 2 and the rain grate to slide. One end of the support column 5 facing the main bracket 1 is fixedly installed with a handle 8. By the handle 8, it is convenient to apply force to the support column 5 for easy operation. In the initial state, the handle 8 and the support column 5 are flush with the surface of the main bracket 1 and the surface of the rain grate.

[0024] As Figure 3 and Figure 4 shown, the retaining ring 16 is provided with a guiding channel. A limiting member is arranged between the retaining ring 16 and the support column 5. The limiting member includes a supporting protrusion 9 located in the guiding channel. The guiding channel successively includes a first sliding channel 10, a first rotating channel 11, a second sliding channel 12 and a second rotating channel 13. The length directions of the first sliding channel 10 and the second sliding channel 12 are the same as the length direction of the support column 5, and the length directions of the first rotating channel 11 and the second rotating channel 13 are the same as the circumferential direction of the support column 5. A number of limiting teeth 14 are formed in the second rotating channel 13, and a gap for the supporting protrusion 9 to slide into is formed between two adjacent limiting teeth 14. In the initial state, the supporting protrusion 9 is located at one end of the first sliding channel 10 far from the first rotating channel 11.

[0025] When there is water accumulation on the road surface, the support column 5 is pulled by the handle 8, and the support convex 9 will slide from the first slideway 10 into the first rotating track 11. At this time, the ring convex slides in the limiting groove and abuts against the limiting groove, and the support column 5 protrudes to the surface of the main frame 1. Then, the support column 5 is rotated, and the support convex 9 will slide from the first rotating track 11 into the second slideway 12, and the ring convex slides in the limiting groove. Then, the support column 5 is pulled again, and the support convex 9 will slide from the second slideway 12 into the second rotating track 13, and the ring convex abuts against the limiting groove, so that the support column 5 drives the connecting rod 3, the auxiliary frame 2 and the rainwater grate to slide. The support column 5 is rotated again, and the support convex 9 will slide from the second slideway 12 into the second rotating track 13. When the force on the support column 5 is stopped, the support convex 9 will slide into the space between two adjacent limiting teeth 14. Due to the abutment between the limiting teeth 14 and the support convex 9, the support column 5 cannot rotate or slide, so that the auxiliary frame 2 and the rainwater grate are kept at the position where the opening of the sewer is unblocked, and the rainwater will directly flow into the sewer through the main frame 1, accelerating the drainage and reducing the impact of water accumulation on the road surface traffic. Moreover, the degree to which the support column 5 protrudes to the surface of the main frame 1 increases, and the protruding degree of the support column 5 is higher than that of the rainwater grate.

[0026] As Figure 3 and Figure 4 shown, a reflective strip 15 is fixedly arranged on the outer side of the support column 5. After the support column 5 protrudes to the surface of the main frame 1, by using the reflection of the reflective strip 15, it reminds the surrounding pedestrians and vehicles that the drainage is accelerating here, reducing the risk of pedestrians and vehicles falling into the sewer. There is a drainage groove 6 formed inside the support column 5, and a drainage port 7 communicating with the drainage groove 6 is opened on the side wall of the support column 5. When accelerating the drainage, the drainage port 7 corresponds to the main frame 1, so that the road surface water can enter the sewer through the drainage port 7 and the drainage groove 6, improving the drainage speed.

[0027] In summary, the support casting provided in this embodiment is convenient for moving the rainwater grate, enabling the sewer to drain water at an accelerated speed, reducing the degree of road surface water accumulation. At the same time, it can remind the surrounding area during accelerated drainage, reducing the risk of pedestrians and vehicles falling into the sewer.

All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
