Description

Technical Field

[0001] This utility model relates to the field of threshold protection technology, specifically a finished door threshold protection device. Background Technology

[0002] During home or shopping mall renovations, large decorative materials, equipment, and tools often need to be moved. Carelessness can easily damage surrounding objects, especially thresholds, which are essential passageways. Thresholds can become deformed or damaged. Since thresholds are mostly made of metal, they can also be bumped or knocked by the objects being moved. This not only affects the quality of the project and prolongs the construction period but also easily leads to customer dissatisfaction with the renovation company. To avoid or reduce the various problems caused by exposed thresholds and to increase the standardization of decoration construction, it is necessary to install reinforced protective materials in these areas to reduce and cushion collisions.

[0003] Existing threshold protection devices typically use a high-elasticity rubber plate connected to a steel plate with structural adhesive to prevent door frame deformation. However, these devices lack an adjustable structure, making it inconvenient to limit and protect thresholds of different sizes. Utility Model Content

[0004] The purpose of this utility model is to provide a finished door threshold protection device to solve the problem in the background art that the protection device does not have an adjustable structure and is not convenient for limiting and protecting thresholds of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finished door threshold protection device, comprising a protective block body, a first soft pad fixedly connected to its lower surface, a second soft pad fixedly connected between two of the first soft pads, a limiting groove formed on the side surface of the protective block body, a support slider installed between the two limiting grooves, two guide grooves formed on the surface of the support slider, a positioning support block installed on the inner wall of the guide groove, a positioning groove formed on the surface of the positioning support block, a buffer slider provided on the inner wall of the positioning groove, and a buffer pad fixedly connected to the upper end of the buffer slider.

[0006] Preferably, the surface of the protective block body is inclined, the first soft pad is in contact with the lower surface of the protective block body, and the second soft pad has a serpentine shrinkage design.

[0007] The above technical solution can fill the tiny gap between the protective block body and the threshold, improve the tightness of the connection between the two, and prevent the protective device from shifting during use. On the other hand, it can play a buffering role, absorb the vibration generated during transportation, reduce the impact of vibration on the threshold, and prevent the protective block body from scratching the threshold surface.

[0008] Preferably, the limiting slot and the supporting slider are slidably connected, the supporting slider is provided with blocks at both ends, and a spring is connected between the supporting slider and the limiting slot.

[0009] By adopting the above technical solution, the support slider can move flexibly along the limiting slot, thereby adjusting the position of the support slider according to the threshold of different sizes, realizing the adaptation to thresholds of different widths and thicknesses, and solving the problem that existing protection devices cannot be adjusted and have poor adaptability.

[0010] Preferably, the guide groove and the positioning support block are slidably connected, the positioning support block is a long strip design, and the positioning groove and the buffer slider are slidably connected.

[0011] By adopting the above technical solution, the contact area with the threshold is increased, allowing the supporting force to be distributed more evenly on the threshold surface, avoiding excessive local pressure that could cause threshold deformation. At the same time, the elongated structure improves the structural stability of the positioning support block itself, making it less prone to bending or damage and extending the service life of the protection device.

[0012] Preferably, the surface of the buffer pad is arc-shaped, and a spring is connected between the lower surface of the buffer pad and the positioning support block, and an anti-detachment plate is fixedly connected to the lower end of the buffer slider.

[0013] By adopting the above technical solution, the contact stress between the object and the buffer pad is reduced, avoiding damage to the object or the buffer pad caused by sharp contact. At the same time, the curved surface can guide the object to slide, reduce friction during handling, make the object pass through more smoothly, and reduce the lateral pressure on the threshold.

[0014] Preferably, a rubber pad is fixedly connected to the lower surface of the anti-detachment plate. The rubber pad is a long strip design, and the lower end of the rubber pad is an arc design.

[0015] Using the above technical solution, the rubber material has good elasticity and anti-slip properties, which can increase the friction between the anti-detachment plate and the threshold, prevent the overall displacement of the protective device, and improve the stability after installation. At the same time, the elasticity of the rubber can further absorb vibration and impact, playing an auxiliary buffering role.

[0016] Preferably, a guide rail is fixedly connected to the upper side surface of the protective block body, and the guide rail and the buffer pad are slidably connected.

[0017] By adopting the above technical solution, the movement trajectory of the buffer pad is restricted, the stability of the buffer structure is improved, the buffer pad is prevented from tilting or misaligning when it is impacted, and the buffering force is accurately transmitted to the spring to achieve efficient buffering. At the same time, the sliding connection method reduces the friction during the buffering process, reduces component wear, and extends the service life of the protection device.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the finished product protection device for the entrance door threshold: 1. By using the sliding connection between the limiting slot and the supporting slider, and the sliding cooperation between the guide groove and the positioning support block, the position of each component can be flexibly adjusted according to the different widths and thicknesses of the entrance door thresholds, breaking the problem of "fixed size and poor adaptability" of traditional protection devices, and achieving precise protection for thresholds of various specifications; 2. The first soft pad and the serpentine shrinking second soft pad form the bottom layer of buffer, absorbing the vibration between the protective block body and the threshold; the spring under the buffer pad, the spring between the support slider and the limiting slot form the middle layer of buffer, dispersing the impact force of the object; the elasticity of the rubber pad provides the top layer of auxiliary buffer. The three layers of protection greatly reduce the risk of threshold deformation, damage and bumping of moving objects. 3. The anti-detachment plate prevents the buffer slider from falling out of the positioning groove, the blocks at both ends of the support slider prevent it from falling out of the limit slot, the guide rail ensures that the buffer pad slides without deviation, and the structural design of long strip positioning support block, arc-shaped buffer pad block, etc. not only improves the stability of the components, but also reduces wear and extends the overall service life of the device.

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a finished door threshold protection device, including a protective block body 1, a first soft pad 2, a second soft pad 3, a limiting groove 4, a support slider 5, a guide groove 6, a positioning support block 7, a positioning groove 8, a buffer slider 9, a buffer pad 10, an anti-detachment plate 11, a rubber pad 12, and a guide rail 13. The protective block body 1 has the first soft pad 2 fixedly connected to its lower surface. The surface of the protective block body 1 is inclined. The first soft pad 2 fits against the lower surface of the protective block body 1. The second soft pad 3 has a serpentine contraction design. According to the threshold size, the support slider 5 is pushed to slide along the limiting groove 4 to adjust its lateral position. The blocks at both ends of the support slider 5 prevent slippage. The connected spring assists in fixing the position. At the same time, the positioning support block 7 is pulled to slide along the guide groove 6 to adjust its extension length, so that the rubber pad 12 under the anti-detachment plate 11 fits against the edge of the threshold, completing the adaptation and installation of the device with the threshold.

[0023] A second soft pad 3 is fixedly connected between two first soft pads 2. A limiting groove 4 is opened on the side surface of the protective block body 1. A support slider 5 is installed between the two limiting grooves 4. The limiting grooves 4 and the support slider 5 form a sliding connection. Stops are set at both ends of the support slider 5. A spring is connected between the support slider 5 and the limiting groove 4. The guide groove 6 and the positioning support block 7 form a sliding connection. The positioning support block 7 is a long strip design. The positioning groove 8 and the buffer slider 9 form a sliding connection. When moving large materials or tools, the inclined surface of the protective block body 1 guides the object to slide smoothly. The arc-shaped buffer pad 10 further reduces the contact resistance between the object and the device, avoids the object from getting stuck or scratched, reduces the difficulty of handling, and protects the surface of the object.

[0024] The surface of the support slider 5 is provided with two guide grooves 6. The inner wall of the guide grooves 6 is equipped with positioning support blocks 7. The surface of the positioning support blocks 7 is provided with positioning grooves 8. The surface of the buffer pad 10 is arc-shaped, and a spring is connected between the lower surface of the buffer pad 10 and the positioning support block 7. The lower end of the buffer slider 9 is fixedly connected with an anti-detachment plate 11. If an object hits the buffer pad 10, the buffer pad 10 will push the buffer slider 9 down along the positioning groove 8 after being subjected to force. The spring connected to it will be compressed and deformed to absorb most of the impact energy. At the same time, the spring between the support slider 5 and the limiting groove 4 will contract synchronously to disperse the impact force a second time and reduce the transmission of force to the threshold.

[0025] The inner wall of the positioning groove 8 is provided with a buffer slider 9. The upper end of the buffer slider 9 is fixedly connected to a buffer pad 10. The lower surface of the anti-detachment plate 11 is fixedly connected to a rubber pad 12. The rubber pad 12 is a long strip design and the lower end of the rubber pad 12 is an arc design. The upper side surface of the protective block body 1 is fixedly connected to a guide rail 13, and the guide rail 13 and the buffer pad 10 form a sliding connection. After the impact, the spring under the buffer pad 10 and the spring next to the support slider 5 are reset respectively, driving the buffer slider 9 and the support slider 5 back to the initial position. The anti-slip property of the rubber pad 12 ensures that the device does not shift. The guide rail 13 restricts the movement trajectory of the buffer pad 10, ensuring that the device continues to play a stable protective role.

[0026] Working principle: When using this door threshold protection device, push the support slider 5 to slide along the limiting slot 4 to fix the lateral position, and pull the positioning support block 7 along the guide slide 6 to adjust the extension length so that the rubber pad 12 fits the threshold, completing the fitting installation. When moving objects, the inclined surface of the protective block body 1 and the arc-shaped buffer pad 10 guide the object to slide smoothly. If the object hits the buffer pad 10, the buffer slider 9 slides down along the positioning slide 8, and the spring below it is compressed to absorb energy. The springs between the support slider 5 and the limiting slot 4 buffer synchronously, reducing the transmission of impact force. After the impact, each spring returns to its original position, the rubber pad 12 is anti-slip, and the guide slide 13 is limited, ensuring that the device is stably reset and continuously protects the threshold, increasing the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
