Description

Technical Field

[0001] The present invention relates to the technical field of damping device decoration protection, and more specifically, the present invention relates to an openable damping device decoration protection device. Background Technique

[0002] Traditional dampers are enclosed with gypsum boards during decoration and renovation. When performing later maintenance, the decoration and renovation need to be damaged. Moreover, once personnel knock on the gypsum board during the decoration process, it will also cause structural looseness of the damper between the walls, affecting the structural safety of the wall.

[0003] The patent with the patent application publication number CN208329444U discloses a composite gypsum board, including: an upper card slot, a fiber layer, a gypsum layer, a heat dissipation pipe, a plant straw paper-faced gypsum layer, and a lower card slot. The upper and lower ends of the fiber layer are respectively provided with the upper card slot and the lower card slot. The gypsum layer is fixedly clamped to the fiber layer through the upper card slot. The plant straw paper-faced gypsum layer is fixedly clamped to the fiber layer through the lower card slot. The heat dissipation pipe is also provided inside the fiber layer. The advantages of this utility model: Using the plant straw paper-faced gypsum layer as the bottom layer of the gypsum board reduces the overall weight of the gypsum board and lowers the cost; card slots are provided on the fiber layer to clamp and fix the gypsum layer and the plant straw paper-faced gypsum layer, making the assembly convenient and stable; heat dissipation pipes are provided inside the fiber layer to gradually expand the heat through the pipes to ensure uniform overall heat reception.

A second power-on reset button is provided on one side of the collar block.

[0008] Preferably, both sides of the extrusion ring are fixedly connected between the extrusion spring and the concave collar plate in pairs. The first guiding pillar is movably connected to the concave collar plate. Both side surfaces of the inclined contact plate are chamfered and polished. The inclined contact plate is made of stainless steel.

[0009] Preferably, a fixing block for supporting the second guiding pillar to achieve a stable effect is welded to the bottom end of the second guiding pillar. The output end of the first power-on reset button is connected to an audible and visual alarm. The output end of the second power-on reset button is connected to a PLC wireless controller. A support block for limiting and supporting the first guiding pillar is installed at one end of the first guiding pillar, and the support block is welded and fixed to the first guiding pillar.

[0010] Preferably, a magnet bar is fixed on one side surface of the fireproof board. A protection component is provided on one side of the magnet bar. The protection component includes a frame plate provided on one side of the magnet bar, and an external reinforcement frame bar for strengthening the outside of the frame plate is provided outside the frame plate. A collar shaft cylinder is fixed on one side of the frame plate, and a transparent glass plate is adhesively bonded to the inner wall of the frame plate through sealant. A middle support block and two vertical brackets are provided on one side of the transparent glass plate, and the two vertical brackets are distributed on the outer wall position of the middle support block. Opposite ends of the two vertical brackets are both fixed with arc brackets. Four inclined support rods are provided on the outer wall of the middle support block and at a position between two adjacent arc brackets. A support arc block and an outward expansion arc bracket are welded between two adjacent inclined support rods, and the outward expansion arc bracket is located on one side of the support arc block. The support shaft is movably connected to the collar shaft cylinder. The arc brackets, vertical brackets, and middle support block are all made of stainless steel.

[0011] Preferably, a reset assembly is fixed on one side of the inner wall of the fireproof board. The reset assembly includes a collar support block fixedly connected to one side of the inner wall of the fireproof board. An infrared distance sensor is threadedly connected inside the collar support block. Two symmetrically arranged linkage push plates are provided below the collar support block. A threaded collar block is welded to one end of the linkage push plate. A servo drive motor is provided on one side of the threaded collar block. A transmission screw is threadedly connected to the inner wall of the threaded collar block. The output end of the servo drive motor is fixedly connected concentrically with the transmission screw. A gap is formed between the collar support block and the linkage push plate. The other end of the transmission screw is provided with a hexagonal limit block for limiting the threaded collar block.

[0012] The technical effects and advantages of the present invention:

[0013] 1. The present invention adopts a multi-stage warning mechanism. The compression spring realizes the compression operation on the support block. The inclined contact plate can squeeze the first power-on reset button, and the sound and light alarm is powered on to emit sound and light alarms. The inclined contact plate continuously squeezes the first power-on reset button. The first power-on reset button drives the collar block to move downward along the outer wall of the second guiding pillar. The collar block squeezes the compression spring, which can start the PLC wireless controller and remotely start the hospital background monitoring computer, and prompts the monitoring personnel that the damper is damaged. In this way, a multi-stage alarm operation is formed during the decoration construction process, avoiding damage to the damper during the decoration process, with better protection effect and higher safety;

[0014] 2. The present invention adopts a protection component. When the damper needs to be repaired, the operator can pull the frame plate. The collar shaft cylinder rotates outside the support shaft. The frame plate is no longer magnetically attracted to the magnet bar, and the frame plate can be opened to check the damper inside the wall. The protruding collar support block protects the frame plate. The outward expansion arc bracket and the support arc block can support the inclined strut. The arc bracket supports the vertical bracket, and cross multi-point support operations are carried out inside the frame plate, so as to protect the front of the transparent glass plate, with better impact resistance and not easily causing damage to the damper;

[0015] 3. In the present invention, a reset component is adopted. Once the inclined contact plate is stuck at the rear position of the first power-on reset button and the sensing distance between the infrared distance sensor and the concave collar plate is less than the set distance, the PLC wireless controller can remotely start the servo drive motor to drive the transmission screw to rotate forward. The threaded collar block drives the two linkage push plates to move leftward. When the concave collar plate drives the extrusion ring to make the inclined contact plate move forward to the front position of the first power-on reset button, the servo drive motor drives the transmission screw to reverse, and the two linkage push plates move rightward to reset to the starting origin position. In this way, the concave collar plate can be reset from the inside, ensuring that the concave collar plate can be reused, completing the reset operation, preventing the inclined contact plate from being stuck behind the first power-on reset button and unable to reset, and ensuring the stable operation of the protection device.

[0016] In summary, through the mutual influence of the above multiple functions, a multi-stage alarm operation is formed during the decoration construction process, avoiding damage to the damper during decoration, having a better protection effect and higher safety. It can provide protection in front of the transparent glass plate, with better impact resistance and not easily causing damage to the damper. The reset operation is completed, preventing the inclined contact plate from being stuck behind the first power-on reset button and unable to reset. In summary, it can effectively improve the protection of the damper during decoration and not easily cause damage to the damper. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As shown in the attached Figures 1-8 figure, a kind of openable damper decoration protection device is provided. A multi-stage early warning mechanism, a contact component, a protection component and a reset component are arranged on the protection device. The settings of each mechanism and component can play a good protection effect on the damper during decoration. The specific structural settings of each mechanism and component are as follows:

[0028] In some embodiments, as shown in the attached Figures 1-3 figure, the multi-stage early warning mechanism includes two first guiding pillars 5 embedded on one side of the concave collar plate 2. An extrusion ring 4 is arranged on the outer wall of the first guiding pillar 5 and at a position on one side of the concave collar plate 2. An extrusion spring 3 is installed on one side of the extrusion ring 4. The bottom end of the outer wall of one of the extrusion rings 4 is fixed with a contact component. The contact component includes an inclined contact plate 6 arranged at the bottom end of the outer wall of one of the extrusion rings 4. A first power-on reset button 7 is arranged on one side of the inclined contact plate 6. A collar block 8 is fixed on one side of the first power-on reset button 7. A second guiding pillar 9 with a hexagonal cross-section at the top and a circular cross-section at the bottom is movably arranged inside the collar block 8. A compression spring 10 for compression is arranged on the outer wall of the second guiding pillar 9 and at a position below the collar block 8. A second power-on reset button 11 is arranged on one side of the collar block 8;

[0029] When the above-mentioned structure is in use and the edge part of the damper is being decorated, once the hammer strikes the frame plate 17, the frame plate 17 can squeeze the magnet strip 16, and the magnet strip 16 squeezes the concave collar plate 2, so that the concave collar plate 2 can move along the outer wall of the first guiding pillar 5. At the same time, the concave collar plate 2 drives the extrusion ring 4 to squeeze the compression spring 3, so that the compression spring 3 realizes the compression operation on the support block 13. The inclined contact plate 6 can squeeze the first power-on reset button 7, and the first power-on reset button 7 powers on the sound and light alarm 15 to emit sound and light alarms, so that the external construction workers can stop construction after seeing it. Once they don't see it and continue to strike the frame plate 17, the concave collar plate 2 drives the extrusion ring 4 to make the inclined contact plate 6 squeeze the first power-on reset button 7, and continuously squeeze the first power-on reset button 7. The first power-on reset button 7 drives the collar block 8 to move downward, and the collar block 8 moves downward along the outer wall of the second guiding pillar 9. The collar block 8 squeezes the compression spring 10 to complete the compression operation on the fixed block 12. In this way, the inclined contact plate 6 moves to the rear position of the first power-on reset button 7 and touches the second power-on reset button 11, so that the PLC wireless controller 14 can be started, the hospital background monitoring computer can be remotely started, and the monitoring personnel can be prompted that the damper is damaged. Therefore, the background monitoring personnel can communicate by phone in time to stop knocking, which plays a multi-stage protection operation, effectively avoiding the damage of the damper during decoration and ensuring the safety of the wall.

[0030] In some embodiments, as shown in the attached Figure 3 figure, both sides of the extrusion ring 4 are fixedly connected to the compression spring 3 and the concave collar plate 2 in pairs. The first guiding pillar 5 is movably connected to the concave collar plate 2 to facilitate the guiding movement of the concave collar plate 2 along the outer wall of the first guiding pillar 5. The extrusion ring 4 squeezes the compression spring 3, so that the compression spring 3 realizes the compression operation on the support block 13. Both side surfaces of the inclined contact plate 6 are chamfered and polished. The inclined contact plate 6 is made of stainless steel to facilitate driving the extrusion ring 4 to make the inclined contact plate 6 squeeze the first power-on reset button 7 and continuously squeeze the first power-on reset button 7, and the first power-on reset button 7 drives the collar block 8 to move downward, achieving the effect of smooth inclined extrusion.

[0031] In some embodiments, as shown in the attached Figures 3-4As shown in the figure, a fixing block 12 for supporting the second guiding pillar 9 to achieve a stable effect is welded to the bottom end of the second guiding pillar 9. The output end of the first power-on reset button 7 is connected to an audible and visual alarm 15, and the output end of the second power-on reset button 11 is connected to a PLC wireless controller 14. In this way, when the first power-on reset button 7 powers on the audible and visual alarm 15 to give an audible and visual alarm to prompt the workers on-site, when the second power-on reset button 11 is touched, the PLC wireless controller 14 can be started to remotely start the hospital background monitoring computer to prompt the monitoring personnel that the damper is damaged, so as to prompt through the background personnel remotely to avoid damage to the damper during the decoration process. One end of the first guiding pillar 5 is provided with a supporting block 13 for limiting and supporting the first guiding pillar 5, and the supporting block 13 is fixedly welded to the first guiding pillar 5, so that the compression spring 3 can perform a compression operation on the supporting block 13 to ensure that the compression spring 3 performs a stable compression operation.

[0032] In some embodiments, as shown in the appendix Figures 2-6 As shown in the figure, a magnet bar 16 is fixed on one side surface of the fireproof board 1. A protective component is arranged on one side of the magnet bar 16. The protective component includes a frame board 17 arranged on one side of the magnet bar 16, and an external reinforcement frame bar 18 for reinforcing the outside of the frame board 17 is arranged outside the frame board 17. A sleeve ring shaft cylinder 19 is fixed on one side of the frame board 17, and a transparent glass plate 21 is adhered to the inner wall of the frame board 17 through sealant. A middle support block 22 and two vertical brackets 23 are arranged on one side of the transparent glass plate 21, and the two vertical brackets 23 are distributed at the outer wall position of the middle support block 22. Arc brackets 24 are fixed at the opposite ends of the two vertical brackets 23. Four inclined support rods 25 are arranged on the outer wall of the middle support block 22 and between two adjacent arc brackets 24. A support arc block 26 and an outward expansion arc bracket 27 are welded between two adjacent inclined support rods 25, and the outward expansion arc bracket 27 is located on one side of the support arc block 26. The support shaft 20 is movably connected with the sleeve ring shaft cylinder 19. The arc brackets 24, the vertical brackets 23, and the middle support block 22 are all made of stainless steel material;

[0033] When the above structure is in use, when the damper needs to be repaired, the operator can pull the frame plate 17. The frame plate 17 drives the collar shaft cylinder 19 to rotate outside the support shaft 20, and the frame plate 17 is no longer magnetically attracted to the magnet bar 16, so the separation operation can be realized. In this way, the frame plate 17 can be opened to check the damper inside the wall, and the repair operation can be carried out. When damaged, the collar support block 28 protrudes to protect the frame plate 17. The outward expansion arc bracket 27 and the support arc block 26 can support the inclined strut 25. The inclined strut 25 supports the middle support block 22, and the arc bracket 24 supports the vertical bracket 23. The vertical bracket 23 supports the middle support block 22. In this way, cross multi-point support operation can be carried out inside the frame plate 17, so as to protect the front of the transparent glass plate 21, and it is not easy to damage the frame plate 17 and break the transparent glass plate 21, playing a role of high safety protection.

[0034] In some embodiments, as shown in the appendix Figures 2-7 As shown, a reset assembly is fixed on one side of the inner wall of the fireproof board 1. The reset assembly includes a collar support block 28 fixedly connected to one side of the inner wall of the fireproof board 1. An infrared distance sensor 29 is threadedly connected inside the collar support block 28. There are two symmetrically arranged linkage push plates 30 below the collar support block 28. A threaded collar block 31 is welded to one end of the linkage push plate 30. A servo drive motor 33 is provided on one side of the threaded collar block 31, and a transmission screw 32 is threadedly connected to the inner wall of the threaded collar block 31. The output end of the servo drive motor 33 is fixedly connected to the transmission screw 32 concentrically. A gap is formed between the collar support block 28 and the linkage push plate 30. The other end of the transmission screw 32 is provided with a hexagonal limit block 34 for limiting the threaded collar block 31;

[0035] When the above structure is in use, after the inclined contact plate 6 comes into contact with the second power-on reset button 11, under the action of the resilience of the compression spring 3, once the inclined contact plate 6 gets stuck behind the first power-on reset button 7, the infrared distance sensor 29 can be supported by the collar support block 28. When the sensing distance between the infrared distance sensor 29 and the concave collar plate 2 is less than the set distance, the PLC wireless controller 14 can remotely start the servo drive motor 33 to drive the transmission screw 32 to rotate forward. The transmission screw 32 drives the threaded collar block 31 to move leftward under the action of the thread. The threaded collar block 31 drives the two linkage push plates 30 to move leftward, so that the linkage push plates 30 can squeeze the side position of the concave collar plate 2. When the concave collar plate 2 drives the extrusion ring 4 to move the inclined contact plate 6 forward to a position in front of the first power-on reset button 7, when the sensing distance between the infrared distance sensor 29 and the concave collar plate 2 is greater than the set distance, the PLC wireless controller 14 can start the servo drive motor 33 to drive the transmission screw 32 to reverse. In this way, the threaded collar block 31 drives the two linkage push plates 30 to move rightward to reset to the starting origin position, thus preventing the inclined contact plate 6 from getting stuck behind the first power-on reset button 7 and unable to reset for continuous use, ensuring the normal operation of the protection device.

[0036] In the electrical structure designed in this technical solution, the models used for components such as the PLC wireless controller 14, the sound and light alarm 15, the first power-on reset button 7, the second power-on reset button 11, the infrared distance sensor 29, and the servo drive motor 33 are not specifically limited. Any model type that can meet the implementation of this technical solution and achieve the expected effect can be used.
