Description

Technical Field

[0001] This utility model relates to the field of drainage structure technology, specifically a roof drainage structure. Background Technology

[0002] The roof is the outermost outer envelope of a building, typically consisting of a horizontally installed top slab and parapet walls surrounding it. To promptly drain rainwater from the roof, drainage channels are usually installed. These channels connect to the building's drainage system via drainpipes at their base.

[0003] To prevent debris from clogging building drainage systems, filter plates are typically installed at the openings of drainage channels. These filter plates have multiple perforations that allow water to pass through while blocking debris, preventing it from entering the drainage system and causing blockages. However, over time, viscous debris such as silt can accumulate inside the perforations, clogging them and hindering drainage. Therefore, the filter plates need to be removed and the perforations cleaned. However, because the filter plates are embedded in the drainage channel opening with a tight fit and minimal gaps, tools are required to pry them out, making the process cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a roof drainage structure to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a roof drainage structure, including a drainage channel, a drainage pipe connected to the bottom of the drainage channel, a filter plate provided at the opening of the drainage channel, and locking blocks provided on both sides of the filter plate. Vertical slots for the locking blocks to engage are provided on the inner walls of both sides of the drainage channel. Each locking block is provided with a latch, which is retractable. A limiting groove for the latch to engage is provided on the side wall of each slot. A pushing component is provided inside the slot, which is used to push the locking block out of the slot in a natural state.

[0006] As a further feature of this invention, the lifting assembly includes a spring fixedly connected to the bottom wall of the slot, and a push block is connected to the spring.

[0007] As a further feature of this invention, the push block is provided with an insertion hole, and the card block is provided with an insertion block for inserting into the insertion hole.

[0008] As a further feature of this invention, the card block has a movable groove inside, and the card tongue is slidably connected inside the movable groove.

[0009] As a further feature of this invention, the card block is provided with a sliding groove, and the card tongue is provided with a slider that passes through the sliding groove.

[0010] As a further feature of this invention, the filter plate is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the filter plate needs to be disassembled, this utility model only requires adjusting the retraction of the latch to disengage it from the slot, thereby releasing the slot's restriction on the latch and unlocking the filter plate. The filter plate is then in its natural state, allowing the lifting component to push the locking block out of the slot, pushing the filter plate out of the drain groove. This creates a sufficient gap between the filter plate and the drain groove, facilitating finger insertion and force application, allowing the filter plate to be easily removed without tools. The operation is convenient, time-saving, and labor-saving. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4As shown, a roof drainage structure includes a drainage channel 1, a drainage pipe 2 connected to the bottom of the drainage channel 1, and a filter plate 3 installed at the opening of the drainage channel 1. The filter plate 3 is made of stainless steel, which has high strength and hardness, is not easy to rust, and has good durability. The filter plate 3 has multiple water-permeable holes. A locking block 4 is installed on both sides of the filter plate 3, and a slot 5 for the locking block 4 to be engaged is vertically opened on the inner wall of both sides of the drainage channel 1. A latch 6 is installed on each locking block 4. The latch 6 is retractable, and a limiting groove 7 for the latch 6 to be engaged is opened on the side wall of the slot 5. A pushing component is installed inside the slot 5 to push the locking block 4 out of the slot 5 in a natural state. When it is necessary to remove the filter plate 3, simply adjust the latch 6 to retract, so that it exits the slot 5, thus releasing the latch 6 from the slot 5. The limit switch releases the lock on the filter plate 3, allowing it to be in its natural state. The lifting component then pushes the locking block 4 out of the slot 5, pushing the filter plate 3 out of the drain trough 1. This creates a sufficient gap between the filter plate 3 and the drain trough 1, allowing for easy finger insertion and force application. The filter plate 3 can be easily removed without tools, making the operation convenient, time-saving, and labor-saving. The locking block 4 has a movable groove inside, and the latch 6 slides within this groove. The movable groove allows the latch 6 to extend and retract smoothly within the locking block 4. The locking block 4 has a sliding groove 12, and the latch 6 has a slider 13 that passes through the sliding groove 12. By pushing the slider 13 to slide within the sliding groove 12, the latch 6 can be extended or retracted into the movable groove, making the operation easy and labor-saving.

[0020] Please see Figure 3 , Figure 4 As shown, the lifting assembly includes a spring 8 fixedly connected to the bottom wall of the slot 5, and a push block 9 connected to the spring 8. After the filter plate 3 is embedded into the drain groove 1, the block 4 will be inserted into the slot 5, thereby contacting and squeezing the spring 8 with the push block 9, causing the spring 8 to compress and deform. Then, the latch 6 is adjusted to extend and engage with the limiting groove 7. By limiting the latch 6 with the limiting groove 7, the filter plate 3 can be fixedly installed. Furthermore, because the spring 8 is under pressure, it will push the block 4 in the opposite direction, making the connection between the latch 6 and the limiting groove 7 more stable. It is solid and not easy to shake. When the filter plate 3 needs to be disassembled, simply adjust the tongue 6 to retract, and the spring 8 will automatically extend and return to its original shape after being freed from the pressure restraint. Thus, the push block 9 pushes the block 4 out of the slot 5, which is relatively convenient to operate. The push block 9 has an insertion hole 10, and the block 4 is provided with an insertion block 11 for inserting into the insertion hole 10. When the block 4 is inserted into the slot 5, it will abut against the push block 9, thus inserting the insertion block 11 into the insertion hole 10. Through the cooperation between the insertion block 11 and the insertion hole 10, the block 4 is not easy to slip when it squeezes the push block 9.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
