Description

Technical Field

[0001] This utility model relates to the field of smoke alarm technology, specifically to an indoor smoke alarm installation device. Background Technology

[0002] Smoke alarm devices can detect smoke and sound an alarm immediately when a fire occurs, providing people on site with time to escape and reducing loss of property and life. Smoke alarms are generally installed using an installation device.

[0003] In existing technologies, smoke sensors are typically installed using methods such as adhesive bonding, magnetic adsorption, or clip-on connections for quick fixation and ease of maintenance. However, with adhesive fixation, the adhesive strength gradually decreases over time or due to vibration, and the magnetism weakens, leading to the smoke sensor falling off. While clip-on installation offers better stability, disassembly requires workers to repeatedly remove each clip individually, significantly increasing their workload. Furthermore, during use, accidental activation during cleaning can cause the clips to malfunction, resulting in the smoke alarm falling off unexpectedly, making it inconvenient to use. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an indoor smoke alarm installation device. This device solves the problem of relying on clips for fixing, which requires workers to repeatedly remove each clip. This repetitive operation significantly increases the workload of workers. Furthermore, during use, the clips are easily triggered during cleaning, leading to accidental failure and the smoke alarm falling off, making it inconvenient to use.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an indoor smoke alarm installation device, comprising a base and a smoke alarm body, wherein four mounting plates are installed on the outer periphery of the base, each of the four mounting plates has a threaded hole fixed on its top, and each of the four threaded holes has a fastening bolt threaded on it; four fixing blocks are installed on the top of the smoke alarm body, and each of the four fixing blocks has a limit groove on its side; and a fixing mechanism adapted to the limit groove is provided on the base. The fixing mechanism includes slots formed at the bottom of the base that are adapted to the four fixing blocks. The base has four movable cavities that are respectively connected to the four slots. Movable blocks are slidably installed in each of the four movable cavities. Trapezoidal blocks adapted to the limiting grooves are installed on the sides of each of the four movable blocks. Compression springs are installed on the sides of each of the four movable blocks. The other ends of the four compression springs are respectively installed on the inner side walls of the four movable cavities. Pull ropes are installed on the sides of each of the four movable blocks. A drive assembly for simultaneously winding up the four pull ropes is provided on the base.

[0006] Preferably, the driving assembly includes a driving cavity formed on the base, a rotating rod rotatably mounted on the inner side wall of the driving cavity, rope holes communicating with the driving cavity being formed on the inner side walls of the four movable cavities, the other ends of the four pull ropes passing through the four rope holes and mounted on the rotating rod, a placement groove being formed on the outer periphery of the base, an avoidance hole adapted to the rotating rod being formed on the inner side wall of the placement groove, a movable cavity being formed on the rotating rod, a movable plate being slidably mounted in the movable cavity, a rectangular moving column being mounted on the side of the movable plate, a rectangular hole adapted to the rectangular moving column being formed at the end of the rotating rod, one end of the rectangular moving column extending outside the base and being mounted with a force-applying block, a triangular block being mounted on the side of the force-applying block, a plurality of decorative blocks identical to the force-applying block and the triangular block being mounted on the outer periphery of the base, and an elastic unit being provided on the side of the movable plate.

[0007] Preferably, the elastic unit includes a tension spring mounted on the movable plate, with the other end of the tension spring mounted on the inner side wall of the movable cavity.

[0008] Preferably, the rotating rod is fitted with multiple annular partitions.

[0009] Preferably, the side of the force-applying block is equipped with two limiting blocks that are adapted to the placement groove, and the side of the triangular block is fixed with striped markings.

[0010] Preferably, four L-shaped limiting posts are installed on the outer periphery of the smoke alarm body, and the tops of the four L-shaped limiting posts abut against the nuts of the four fastening bolts respectively.

[0011] The beneficial effects of this utility model are as follows: This invention, through the arrangement of a moving block, a compression spring, a rotating rod, a pull rope, a rectangular moving column, a force-applying block, and a movable plate, allows four trapezoidal blocks to move simultaneously, thereby fixing or releasing the smoke alarm body from four sides. This eliminates the need for repeated adjustments, avoids repetitive operations, and reduces the labor intensity of workers. Simultaneously, the rectangular moving column and movable plate allow the force-applying block to move, and the applied force causes the limiting block to move. When not in use, the limiting block is positioned within its slot, preventing it from rotating and thus fixing the force-applying block. This prevents the force-applying block and rotating rod from rotating and affecting the fixation. Furthermore, the force point is located on the base, preventing damage to the rotating rod and rectangular moving column from excessive external forces.

[0012] This utility model, through the setting of the tension spring, makes it easy to keep the force-applying block in a certain position when no force is applied after use, and prevents it from sliding back and forth through the rectangular moving column and the movable plate. Through the setting of the L-shaped limiting column, the fastening bolt can be limited after the smoke alarm body is installed, so as to prevent the fastening bolt from rotating due to vibration and affecting the fixation of the base.

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 6 The present invention will be further described below.

[0017] An indoor smoke alarm installation device includes a base 1 and a smoke alarm body 2. Four mounting plates 4 are installed on the outer periphery of the base 1. Threaded holes are fixed to the top of each of the four mounting plates 4, and fastening bolts 5 are threaded into each of the four threaded holes. Four fixing blocks 6 are installed on the top of the smoke alarm body 2. Limiting grooves are opened on the sides of each of the four fixing blocks 6. A fixing mechanism that matches the limiting grooves is provided on the base 1. The fixing mechanism includes slots at the bottom of the base 1 that are adapted to four fixing blocks 6. The base 1 has four movable cavities that are respectively connected to the four slots. Movable blocks 7 are slidably installed in each of the four movable cavities. Trapezoidal blocks 8 that are adapted to limiting grooves are installed on the sides of each of the four movable blocks 7. Compression springs 9 are installed on the sides of each of the four movable blocks 7. The other ends of the four compression springs 9 are respectively installed on the inner side walls of the four movable cavities. Pull ropes 11 are installed on the sides of each of the four movable blocks 7. A drive assembly that simultaneously winds up the four pull ropes 11 is provided on the base 1.

[0018] With the above structure, during use, the trapezoidal block 8 can be retracted and reset by the moving block 7 and the compression spring 9, so that the fixed block 6 can be pressed directly when it is compressed and fixed without adjustment. At the same time, the drive component can wind up the four pull ropes 11. The winding of the four pull ropes 11 will move the moving block 7, thereby moving the four trapezoidal blocks 8 to release the fixation of the smoke alarm body 2. Thus, the fixation of the smoke alarm body 2 can be released without repeatedly adjusting multiple moving blocks 7, avoiding repeated operations.

[0019] like Figure 4 - Figure 6As shown, the drive assembly includes a drive cavity opened on the base 1. A rotating rod 10 is rotatably mounted on the inner side wall of the drive cavity. The inner side walls of the four movable cavities are all provided with rope holes communicating with the drive cavity. The other ends of the four pull ropes 11 pass through the four rope holes and are installed on the rotating rod 10. A placement groove is opened on the outer periphery of the base 1. An avoidance hole adapted to the rotating rod 10 is opened on the inner side wall of the placement groove. A movable cavity is opened on the rotating rod 10. A movable plate 15 is slidably installed in the movable cavity. A rectangular moving column 13 is installed on the side of the movable plate 15. A rectangular hole adapted to the rectangular moving column 13 is opened at the end of the rotating rod 10. One end of the rectangular moving column 13 extends to the outside of the base 1 and is provided with a force-applying block 14. A triangular block is installed on the side of the force-applying block 14. A plurality of decorative blocks 18 identical to the force-applying block 14 and the triangular block are installed on the outer periphery of the base 1. An elastic unit is provided on the side of the movable plate 15.

[0020] In this design, the arrangement of the rotating rod 10, the rectangular moving column 13, the force-applying block 14, the movable plate 15, the triangular block and the decorative block 18 facilitates the simultaneous movement of the four moving blocks 7.

[0021] Specifically, by moving the four movable blocks 7 simultaneously, the four trapezoidal blocks 8 can be moved simultaneously, thereby releasing the smoke alarm body 2 from all four sides at the same time, thus eliminating the need for repeated adjustments and reducing the workload of the staff.

[0022] like Figure 6 As shown, the elastic unit includes a tension spring 16 mounted on the movable plate 15, and the other end of the tension spring 16 is mounted on the inner side wall of the movable cavity.

[0023] In this design, the tension spring 16 facilitates the resetting of the rectangular moving column 13.

[0024] Specifically, by resetting the rectangular movable column 13, the rectangular movable column 13 is prevented from being damaged by the external environment. At the same time, the force-applying block 14 is reset to a position similar to the decorative block 18, which has a certain deceptive effect and prevents others from maliciously rotating it.

[0025] like Figure 5 As shown, multiple annular partitions 12 are fitted onto the rotating rod 10.

[0026] In this design, the annular baffle 12 serves as a barrier.

[0027] Specifically, the annular partition 12 prevents the four ropes 11 from getting tangled together.

[0028] like Figure 6 As shown, two limiting blocks 17 adapted to the placement groove are installed on the side of the force-applying block 14, and striped markings are fixed on the side of the triangular block.

[0029] In this scheme, the setting of the limiting block 17 facilitates the limiting of the force application block 14, and the setting of the striped mark facilitates the locating of the triangular block and the force application block 14.

[0030] Specifically, by limiting the position of the limit block 17, the force application block 14 can be fixed so that it cannot rotate, thus preventing accidental contact during cleaning from causing the rotating rod 10 to rotate and affecting the fixation of the smoke alarm body 2. At the same time, the force point is located on the base 1, preventing excessive force from damaging the rotating rod 10 and the rectangular moving column 13.

[0031] like Figure 1 As shown, four L-shaped limiting posts 3 are installed on the outer periphery of the smoke alarm body 2, and the tops of the four L-shaped limiting posts 3 abut against the nuts of the four fastening bolts 5 respectively.

[0032] In this design, the L-shaped limiting post 3 facilitates the limiting of the fastening bolt 5.

[0033] Specifically, by limiting and blocking the fastening bolt 5, the rotation of the fastening bolt 5 due to vibration is prevented from affecting the fixation of the base 1.

[0034] In summary: When using this utility model, firstly, the base 1 is fixed in the designated position using the mounting plate 4 and fastening bolts 5. Then, the smoke alarm body 2 is held so that the fixing block 6 is aligned with the slot and pressed down. When the top of the fixing block 6 contacts the inclined surface of the trapezoidal block 8, the fixing block 6 continues to move upward, squeezing the trapezoidal block 8 and causing it to move. The movement of the trapezoidal block 8 causes the moving block 7 to move. At this time, the compression spring 9 deforms. When the vertical surface of the trapezoidal block 8 contacts the fixing block 6, the trapezoidal block 8 stops moving. Then, the fixing block 6 continues to move. When the limiting groove aligns with the trapezoidal block 8, the trapezoidal block 8 will move between the moving block 7 and the compression spring 9. When spring 9 resets, trapezoidal block 8 resets and fixes fixed block 6, thereby fixing smoke alarm body 2. When it is necessary to release the fixation, locate the triangular block through the striped markings and pull it. The movement of the triangular block will cause force application block 14 to move, and the movement of force application block 14 will cause limit block 17 to move. When limit block 17 moves out of the placement slot, rotate force application block 14. The rotation of force application block 14 will cause rectangular moving column 13 to rotate. The rotation of rectangular moving column 13 will cause rotating rod 10 to rotate with the cooperation of movable plate 15. The rotation of rotating rod 10 will cause pull rope 11 to be wound up. The wound pull rope 11 will cause four moving rods to be wound up. Pulling the movable block 7 causes the trapezoidal block 8 to move, thereby releasing the fixation on the smoke alarm body 2. This eliminates the need to repeatedly adjust multiple movable blocks 7 to release the fixation on the smoke alarm body 2, avoiding repetitive operations. After the fixation is released, the force-applying block 14 resets and rotates, causing the rotating rod 10 to reset, thus canceling the pulling of the movable block 7. When the movable block 7 resets, the pulling of the force-applying block 14 is canceled. At this time, the tension spring 16 pulls the movable plate 15 to reset it. The reset of the movable plate 15 causes the rectangular movable column 13 to reset. This will cause the force-applying block 14 to reset, which will cause the limiting block 17 to reset, and then the limiting block 17 to enter the placement slot. At this time, the limiting block 17 will be blocked by the placement slot and rotate, thereby fixing the force-applying block 14 so that it cannot rotate. This prevents accidental contact during cleaning from causing the rotating rod 10 to rotate and affecting the fixation of the smoke alarm body 2. At the same time, it ensures that the force point is on the base 1, preventing excessive force from damaging the rotating rod 10 and the rectangular moving column 13. In addition, after adjustment, when the force-applying block 14 is reset, it will resemble the decorative block 18, which will have a certain deceptive effect and prevent others from maliciously rotating it.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
