Technical Field
[0001] The utility model relates to the technical field of staircase processing, in particular to a reinforcing device for the outer corner of the staircase tread in old residential areas. Background Art
[0002] In the process of urbanization, as an important part of the city, the maintenance and renovation of the infrastructure in old residential areas have been increasingly emphasized. The staircase, as a key passage for residents' daily travel, its safety performance is directly related to the life and property safety of residents. The outer corners of the staircase treads in old residential areas (i.e., the junctions between the tread edges and the vertical surfaces) often show phenomena such as damage, cracking, and even peeling due to long-term trampling, wear, and environmental erosion by pedestrians. This not only affects the beauty of the staircase but also poses serious safety hazards, bringing inconvenience and risks to residents' travel. At present, there are various methods for repairing and reinforcing staircase treads in the market, such as directly repairing with adhesives such as epoxy resin and installing metal corner strips. However, these methods all have some problems in practical applications. When directly repairing with adhesives such as epoxy resin, the repair materials are prone to aging, have poor durability, and require frequent maintenance. Although the metal corner strips can enhance the strength of the outer corners to a certain extent, their installation is complex and they cannot adapt to staircases of different lengths.
[0003] To solve the above problems, we propose a reinforcing device for the outer corner of the staircase tread in old residential areas. This reinforcing device adopts a modular splicing structure, which is convenient for installation and can also adapt to staircases of different lengths. Summary of the Invention
[0004] To overcome the disadvantages of poor durability in directly repairing with adhesives such as epoxy resin, complex installation of metal corner strips, and inability to adapt to staircases of different lengths, the utility model provides a reinforcing device for the outer corner of the staircase tread in old residential areas. This reinforcing device adopts a modular splicing structure, which is convenient for installation and can also adapt to staircases of different lengths.

Detailed implementation manners
[0020] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but not to limit the present utility model.
[0021] Embodiment 1: A reinforcing device for the external corner of the stair treads in old residential areas, as Figure 1 and Figure 2 shown, includes a horizontal plate 1, a vertical plate 2, a first docking block 3, a sliding rod 301, a clamping block 4, a first elastic member 5, a second docking block 6, an ejecting assembly and a positioning assembly. A vertical plate 2 is rotatably connected to the front part of the horizontal plate 1. Circular holes for connecting screws are formed on both the horizontal plate 1 and the vertical plate 2. First docking blocks 3 are fixedly connected to the left sides of both the horizontal plate 1 and the vertical plate 2. A sliding rod 301 is slidably connected inside the first docking block 3. A clamping block 4 is fixedly connected to the sliding rod 301. The clamping block 4 extends outside the first docking block 3. A first elastic member 5 is connected between the sliding rod 301 and the adjacent first docking block 3. Second docking blocks 6 are fixedly connected to the right sides of both the horizontal plate 1 and the vertical plate 2. One side of the clamping block 4 away from the horizontal plate 1 and the vertical plate 2 is inclined. The clamping block 4 is in extrusion fit with the second docking block 6. A square groove is provided on one side of the second docking block 6 close to the clamping block 4. An ejecting assembly for ejecting the clamping block 4 is provided inside the second docking block 6. A positioning assembly is provided on the horizontal plate 1 and the vertical plate 2. The positioning assembly is used to lock the angle between the horizontal plate 1 and the vertical plate 2.
[0022] When using this device, the staff controls it to rotate to an appropriate angle on the horizontal plate 1 to fit the angle of the external corner of the staircase, avoiding hollowing. After adjustment, the angle between the horizontal plate 1 and the vertical plate 2 is fixed through the positioning component. Then, the staff moves two identical reinforcement devices closer to each other, so that the second docking block 6 contacts the clamping block 4 on another horizontal plate 1 and vertical plate 2, and then squeezes the clamping block 4 to retract into the first docking block 3. The sliding rod 301 slides in the first docking block 3 accordingly, and the first elastic member 5 deforms. When the second docking block 6 fits with the first docking block 3 on another horizontal plate 1 and vertical plate 2, the clamping block 4 better moves to the square groove on the second docking block 6. Under the action of the reset of the first elastic member 5, the sliding rod 301 drives the clamping block 4 to move outwards and snap into the second docking block 6, thereby connecting the second docking block 6 on one reinforcement device and the first docking block 3 on another reinforcement device together to achieve the purpose of splicing two reinforcement devices. The staff can freely splice multiple reinforcement devices according to the length of the staircase. When this device is spliced to an appropriate length, the staff can insert screws into the staircase through the round holes, and then fix this device on the staircase to reinforce the external corner. When this device needs to be disassembled, the staff can eject the clamping block 4 from the second docking block 6 through the ejection component, and at this time, the mutually spliced reinforcement devices can be disassembled.
[0023] Embodiment 2: On the basis of Embodiment 1, as Figure 3 shown, the ejection component includes a lower pressing plate 7, an ejection rod 8 and a second elastic member 9. The lower pressing plate 7 is slidably connected in the second docking block 6. The ejection rod 8 is fixedly connected to the lower pressing plate 7. A second elastic member 9 is connected between the lower pressing plate 7 and the adjacent second docking block 6.
[0024] When this device needs to be disassembled, the staff pushes the lower pressing plate 7 to slide inwards, and the second elastic member 9 deforms. The inward sliding of the lower pressing plate 7 drives the ejection rod 8 to slide inwards and extend into the square groove, thereby pushing the clamping block 4 stuck in the square groove to separate from the second docking block 6. At this time, the mutually spliced reinforcement devices can be disassembled. After disassembly, the staff releases the lower pressing plate 7, and under the action of the reset of the second elastic member 9, the lower pressing plate 7 drives the ejection rod 8 to slide in the reverse direction and reset.
[0025] As Figure 1 , Figure 4 and Figure 5 shown, the positioning component includes a clamping ring 10, a guiding block 11, a clamping rod 12 and a third elastic member 13. The clamping ring 10 is fixedly connected to the left front part of the horizontal plate 1. The guiding block 11 is fixedly connected to the upper left side of the vertical plate 2. The clamping rod 12 is slidably connected in the guiding block 11. A circle of grooves adapted to the upper end of the clamping rod 12 is formed on the clamping ring 10. A third elastic member 13 is connected between the clamping rod 12 and the guiding block 11.
[0026] When using the device, when the staff controls the vertical plate 2 to rotate on the horizontal plate 1, the clamping rod 12 will also rotate together with the vertical plate 2. When the clamping rod 12 rotates, it is squeezed and slides downward by the clamping ring 10, and the third elastic member 13 deforms. When the vertical plate 2 rotates to an appropriate angle, under the action of the third elastic member 13, the clamping rod 12 slides upward and resets to be clamped into the card slot, thereby fixing the angle between the horizontal plate 1 and the vertical plate 2 for installation.
[0027] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variants of the present invention will be included within the scope of the claims herein.
