Description

Technical Field

[0001] This utility model relates to the field of building decoration protection technology, and in particular to a corner protection device for building wall decoration. Background Technology

[0002] During the construction of interior and exterior decoration of buildings, the external corners of walls, as protruding parts of the structure, are easily subjected to collisions, scratches or impacts during construction activities such as material transportation, equipment movement, and personnel operations. This can lead to quality defects such as cracking of the plaster layer, damage to facing bricks, and peeling of paint. This not only affects the aesthetics and integrity of the wall, but may also increase the cost of later maintenance and reduce the overall quality of the project. Therefore, in order to solve the above problems, external corner protection devices are commonly used on construction sites to temporarily protect the external corners of walls that have not yet been handed over for use.

[0003] Currently, traditional protection methods mainly include wooden corner protectors, PVC plastic corner protectors, metal corner protectors, or simply pasted foam strips. However, these traditional solutions have significant shortcomings. For example, rigid protective structures such as wooden strips and metal angle steel, although possessing high compressive strength and durability, lack elasticity and buffering capacity, failing to effectively absorb and dissipate external impact energy. When subjected to a large impact, the impact force will be directly transmitted to the external corner of the wall, easily causing localized damage to the base layer or finishing materials. At the same time, the edges of rigid materials are relatively sharp, which may also cause secondary injuries to construction workers or other facilities, resulting in poor safety. On the other hand, flexible protective structures such as foam and rubber strips, although possessing certain elasticity and energy absorption characteristics, can play a buffering role in minor collisions. However, their structural strength is low, and long-term use is prone to permanent compression deformation, tearing, or aging and detachment, making it difficult to withstand frequent or high-intensity impact loads.

[0004] Therefore, there is an urgent need to provide a building wall decoration corner protection device that has reliable structural stability, can efficiently absorb impact energy, and is reusable. Utility Model Content

[0005] In order to overcome the shortcomings of existing traditional rigid protective structures and flexible material protective structures, such as insufficient strength, poor buffering and energy absorption effect, easy damage and non-reusability, this utility model provides a building wall decoration corner protection device with reliable structural stability, efficient absorption of impact energy and reusability.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a corner protection device for architectural wall decoration, comprising a protective shell, an elongated opening along the axial direction on the outer wall of the protective shell, a buffer block slidably installed inside the elongated opening, symmetrically distributed guide seats on the buffer block, symmetrically distributed guide rods fixedly connected inside each guide seat, a square slider slidably mounted on each guide rod, a first elastic element sleeved on each guide rod, the two ends of the first elastic element being fixedly connected to the guide seat and the square slider respectively, and a connecting rod hinged to one end of each square slider, the other end of the connecting rod being fixedly connected to a fixed seat located inside the protective shell.

[0007] Furthermore, the inner surface of the protective shell is designed as a matching L-shaped fitting surface according to the included angle of the wall's external corner.

[0008] Furthermore, a U-shaped guide shell is fixed to the top and bottom of the protective shell. Multiple arc-shaped sliders are slidably arranged inside the U-shaped guide shell. A protective block is arranged between the multiple arc-shaped sliders. A pressure-sensitive adhesive is provided on the side of the protective block that contacts the wall. A second elastic element connects the arc-shaped sliders and the U-shaped guide shell.

[0009] Furthermore, both the first elastic element and the second elastic element are compression springs.

[0010] Furthermore, both sides of the protective shell are covered with a first protective pad.

[0011] Furthermore, the outer surface of the buffer block is covered with a second protective pad.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a sliding buffer block on the protective shell, and cooperating with the guide seat, guide rod, square slider, connecting rod and first elastic element to form a buffer mechanism, when the external corner is hit by an external impact, the impact force first acts on the buffer block, drives the guide seat to move backward, drives the connecting rod to unfold and pushes the square slider to slide along the guide rod, compresses the first elastic element, and converts kinetic energy into elastic potential energy, realizing multi-level buffering and energy dissipation. This structure significantly improves the ability to absorb collision impact, effectively reduces the stress transmitted to the wall, and after the impact force disappears, each component can automatically return to the initial position, maintain the integrity of the device shape, have multiple impact resistance capabilities, and extend the service life.

[0013] 2. The inner side of the protective shell is designed with an L-shaped fitting surface according to the standard 90° external angle, which can tightly fit most wall external angles. It also features an adaptive clamping structure composed of a U-shaped guide shell, an arc-shaped slider, a protective block, and a second elastic element. It can be opened and closed by manual pressing to adapt to external angles with different angles or slight deviations, improving installation flexibility and versatility. In addition, the protective block forms a pre-tight clamping force on the side of the wall under the elastic force of the second elastic element, and combined with the pressure-sensitive adhesive on the surface, it achieves a composite fixing method, effectively preventing axial slippage, circumferential rotation, or accidental detachment of the device during use, ensuring long-term protective reliability.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A corner protection device for building wall decoration includes a protective shell 1. The inner surface of the protective shell 1 is designed with a matching L-shaped fitting surface according to the included angle of the wall corner to ensure that the device can fit tightly against the wall corner, improving installation stability and protective coverage. The protective shell 1 is made of high-strength engineering plastic, and its smooth surface is not easy to damage the wall. The outer wall of the protective shell 1 has an elongated opening along the axial direction. A buffer block 2 is slidably installed inside the elongated opening. The buffer block 2 can move back and forth within the opening range. The buffer block 2 is made of highly elastic rubber material, which can undergo controllable deformation when subjected to external impact, absorb and dissipate impact energy, significantly reduce the peak load transmitted to the protective shell and the wall, and achieve effective protection of the wall corner. The buffer block 2 is provided with two guide seats 3 symmetrically distributed vertically. Each guide seat 3 has two guide rods symmetrically distributed vertically fixed inside. A square slider 5 is slidably mounted on the guide rod 4. A first elastic element 6 is sleeved on each guide rod 4. The upper and lower ends of the first elastic element 6 are fixedly connected to the guide seat 3 and the square slider 5, respectively. The first elastic element 6 is a compression spring that provides an inward restoring force to the slider. One end of a connecting rod 7 is hinged to each square slider 5. The other end of the connecting rod 7 is fixedly connected to a fixed seat 8 located inside the protective shell 1. There are two fixed seats 8, which correspond one-to-one with the guide seats 3 and are arranged opposite each other. They are fixedly installed on the inner wall of the protective shell 1. The left and right sides of the protective shell 1 are covered with a first protective pad 14 to prevent the device from scratching or damaging surrounding personnel or objects and to enhance friction and anti-slip performance. The outer surface of the buffer block 2 is covered with a second protective pad 15 to improve impact absorption capacity and reduce rigid contact between external impactors and the device, thereby reducing noise and surface wear.

[0022] In use, this device achieves comprehensive physical protection of the corner area by tightly fitting and snapping the inner side of the protective shell 1 against the external corner of the building wall. When the corner area is subjected to a lateral or oblique impact from an external object, the impact force first acts on the surface of the buffer block 2. Since the buffer block 2 is slidably fitted into the elongated opening of the protective shell 1, under the impact load, the buffer block 2, together with the guide seat 3 on it, undergoes horizontal displacement along the opening direction. During this process, each connecting rod 7 changes angle at one end as it moves with the guide seat 3, driving the other end to move the square slider 5 outward along the guide rod 4, thereby compressing the protective shell 2. The first elastic element 6 is placed between the guide seat 3 and the square slider 5. At this time, the kinetic energy is converted into the elastic potential energy of the first elastic element 6, realizing effective energy absorption and buffering. At the same time, multiple sets of symmetrically arranged buffer mechanisms work together to form a spatial multi-point force dispersion mechanism, which significantly improves the overall structure's impact resistance stability and dynamic response capability. When the external impact force is eliminated, under the action of the restoring force of the first elastic element 6, the square slider 5 slides inward along the guide rod 4 to reset, and the connecting rod 7 retracts synchronously, driving the guide seat 3 and the buffer block 2 back to the initial position, completing the automatic reset, maintaining the integrity of the device's shape, and possessing repeated impact resistance capability.

[0023] Example 2: Based on Example 1, please refer to... Figure 4 The protective shell 1 has a U-shaped guide shell 9 fixedly attached to its top and bottom. Inside the U-shaped guide shell 9, two arc-shaped sliders 10 are slidably arranged opposite each other. A protective block 11 is provided between the two corresponding arc-shaped sliders 10. The protective block 11 directly covers the external corner of the wall and serves as the main contact surface. It is made of highly elastic rubber material and can effectively prevent the external corner from being damaged, chipped, or cracked due to collision, scratch, or external impact, thus providing physical protection and extending the service life of the wall. The side of the protective block 11 that contacts the wall surface is provided with a pressure-sensitive adhesive 12, which can be used to achieve auxiliary bonding and fixation with the wall surface. A second elastic element 13 is connected between the arc-shaped slider 10 and the U-shaped guide shell 9. The second elastic element 13 is a compression spring that provides elastic preload and outward restoring force to the arc-shaped slider 10.

[0024] When installing this device, the operator aligns the protective shell 1 with the external corner of the wall to be protected and presses the protective blocks 11 on both sides inward by hand, causing the arc-shaped slider 10 to slide outward synchronously along the inner cavity of the U-shaped guide shell 9. At this time, the second elastic element 13 is compressed and stores elastic potential energy. This action can adjust the included angle between the protective blocks 11 to be small, thus adapting to external corners of walls with different angles or slight deviations, improving the versatility and installation adaptability of the device. Then, the protective shell 1 is installed, and the protective blocks 11 are tightly attached to the two sides of the external corner of the wall to form a stable clamping force. At the same time, the pressure-sensitive adhesive 12 pre-set on the surface of the protective blocks 11 fully adheres to the wall surface. The contact and adhesion further enhance the reliability of the connection between the device and the wall, preventing loosening, slippage or rotation caused by vibration, scratches or human touch. In use, if subjected to lateral impact or slight deflection torque, the second elastic element 13 can achieve dynamic buffering through slight compression and rebound, absorbing some energy. Combined with the damping effect of the pressure-sensitive adhesive 12, it effectively suppresses the rotation or displacement of the protective shell 1 around the external corner axis, ensuring that it always maintains the correct protective posture. When it is necessary to remove the device, simply apply force evenly to open the protective blocks 11 on both sides outward and release the pressure-sensitive adhesive 12 to easily remove it.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
