[0001] The utility model relates to the technical field of smoke alarms which are convenient for disassembly and assembly, in particular to a smoke alarm which is convenient for disassembly and assembly. Background Technique

[0002] The smoke detector is actually another name for a smoke or smoke alarm. The smoke alarm realizes fire prevention by monitoring the concentration of smoke. An ionic smoke sensor is adopted inside. The ionic smoke sensor is a sensor with advanced technology and stable and reliable operation, and is widely used in various fire alarm systems, and its performance is far superior to that of a gas-sensitive resistor type fire alarm.

[0003] The inventor found during the daily use of the smoke alarm that the general smoke alarm is usually fixed on the roof by screws, which leads to the need for workers to disassemble it with a screwdriver when overhauling the smoke alarm. Since the smoke alarm is installed at a high place, it is inconvenient for workers to disassemble and assemble the smoke alarm, which has an impact. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide a smoke alarm which is convenient for disassembly and assembly.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a smoke alarm which is convenient for disassembly and assembly, including a smoke alarm, a card seat is arranged on the upper top of the smoke alarm, a disassembly and assembly device is arranged on the surface of the card seat, a disassembly device is arranged on the surface of the smoke alarm, a screw is threadedly connected to the surface of the card seat, the disassembly and assembly device includes a hollow rod fixedly connected to the bottom of the card seat, a conical block is fixedly connected to the upper top of the smoke alarm, a sliding rod is slidably connected to the side surface of the hollow rod, a first spring is sleeved on the surface of the sliding rod, and two ends of the first spring are respectively fixedly connected to the hollow rod and the end of the sliding rod far away from the hollow rod, and the other end of the sliding rod is fixedly connected to a trapezoidal block.

[0006] The effects achieved by the above components are as follows: With the cooperation of the trapezoidal block and the conical block, it is convenient to disassemble and assemble the smoke alarm and the card seat, and thus the function of convenient disassembly and assembly is achieved. When the smoke alarm needs to be installed and used, the card seat is fixed on the wall by screws, and the smoke alarm is fixed on the surface of the card seat through the disassembly and assembly device, thus completing the installation of the smoke alarm. (The smoke alarm is a well-known product in the market and will not be elaborated here).

[0007] Preferably, an air bag is fixedly connected to one end of the hollow rod, and the air bag is arranged at one end of the hollow rod close to the smoke alarm.

[0008] The effects achieved by the above components are as follows: Under the action of the airbag, when installing the smoke alarm, it will not directly impact one end of the hollow rod, avoiding the phenomenon of rigid contact.

[0009] Preferably, a rectangular groove is formed on the surface of the hollow rod, and a rectangular rod is slidably connected inside the rectangular groove. One end of the rectangular rod is fixedly connected to the upper top of the smoke alarm.

[0010] The effects achieved by the above components are as follows: Under the action of the rectangular groove and the rectangular rod, the phenomenon that the smoke alarm rotates during installation will not occur.

[0011] Preferably, a magnetic plate is fixedly connected to the inner wall of the hollow rod, and an iron sheet is fixedly connected to the upper top of the conical block.

[0012] The effects achieved by the above components are as follows: Under the cooperation of the magnetic plate and the iron sheet, the conical block can be fixed inside the hollow rod. When installing the smoke alarm, insert the conical block into the hollow rod and insert the rectangular rod into the rectangular groove. Then, the phenomenon that the smoke alarm rotates during installation will not occur, and the trapezoidal block will be squeezed to move to both sides. When the iron sheet on the upper top of the conical block is attracted to the magnetic plate and the conical block is separated from the trapezoidal block, the trapezoidal block will move into the hollow rod under the action of the first spring, and then the conical block will be stuck inside the hollow rod. Under the action of the airbag, when installing the smoke alarm, it will not directly impact one end of the hollow rod, avoiding the phenomenon of rigid contact. When disassembling the smoke alarm, pull the sliding rod to both sides, so that the trapezoidal block moves to both sides from the bottom of the conical block, and then pull down the smoke alarm to separate the iron sheet from the magnetic plate, and then disassemble the smoke alarm, thus achieving the function of convenient disassembly and assembly of the smoke alarm.

[0013] Preferably, the disassembly device includes an annular groove formed on the surface of the smoke alarm, a groove is formed on the surface of the annular groove, a convex block is fixedly connected to the other side of the annular groove, a card slot is formed on the inner wall of the convex block, a clamping ring is fixedly connected inside the groove, and the clamping ring is a rubber ring.

[0014] The effects achieved by the above components are as follows: Under the action of the clamping ring and the card slot, the smoke alarm can be disassembled, thus facilitating the maintenance of the components inside the smoke alarm.

[0015] Preferably, a magnetic block is fixedly connected to the inner wall of the groove (), and a magnetic block is fixedly connected to the bottom of the convex block.

[0016] The effects achieved by the above components are as follows: Under the action of the positive pole of one magnetic block and the negative pole of the other magnetic block, the convex block can be firmly inserted into the groove.

[0017] Preferably, a clamping rod is inserted into the side of the smoke alarm, and the clamping rod is inserted into the inside of the convex block.

[0018] The effect achieved by the above components is that under the action of the clamping rod, the convex block can be fixed inside the groove, thereby achieving the fixing effect.

[0019] Preferably, a second spring is sleeved on the surface of the clamping rod, and both ends of the second spring are fixedly connected to the surface of the smoke alarm and the end of the clamping rod away from the smoke alarm respectively.

[0020] The effect achieved by the above components is that under the action of the second spring, the clamping rod is inserted into the convex block in a self-locking manner for fixation. When the smoke alarm is separated from the card seat, pull the clamping rod outwards to separate the clamping rod from the convex block, and separate the smoke alarm through the groove to repair the internal components. After the repair is completed, insert the convex block into the groove again. Under the action of the positive pole of one magnet and the negative pole of the other magnet, the convex block can be firmly inserted into the groove. After the magnets are adsorbed together under the action of magnetism, under the action of the second spring, the clamping rod is inserted into the convex block in a self-locking manner for fixation, thus achieving the disassembly effect.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0022] In the present utility model, by setting a separation device, when the smoke alarm needs to be installed, insert the conical block into the hollow rod and insert the rectangular rod into the rectangular groove. Thus, the smoke alarm will not rotate during installation, and then squeeze the trapezoidal block to move to both sides. When the iron sheet on the top of the conical block is attracted to the magnetic plate and the conical block is separated from the trapezoidal block, the trapezoidal block moves into the hollow rod under the action of the first spring, thereby clamping the conical block inside the hollow rod. Under the action of the airbag, when the smoke alarm is installed, it will not directly impact one end of the hollow rod, avoiding the phenomenon of rigid contact. When disassembling the smoke alarm, pull the sliding rod to both sides to make the trapezoidal block move to both sides from the bottom of the conical block, and pull the smoke alarm downwards to separate the iron sheet from the magnetic plate, thereby disassembling the smoke alarm, thus achieving the effect of convenient disassembly and assembly of the smoke alarm and solving the problem of inconvenient disassembly and assembly of the smoke alarm.

[0029] Example 1, as Figures 1-4 shown, the smoke alarm 1 facilitating disassembly and assembly includes a smoke alarm 1. A card seat 4 is arranged on the upper top of the smoke alarm 1. A disassembly and assembly device 2 is arranged on the surface of the card seat 4. A disassembly device 3 is arranged on the surface of the smoke alarm 1. The surface of the card seat 4 is threadedly connected with a screw 5. When it is necessary to install and use the smoke alarm 1, the card seat 4 is fixed on the wall through the screw 5, and the smoke alarm 1 is fixed on the surface of the card seat 4 through the disassembly and assembly device 2, thereby completing the installation of the smoke alarm 1. (The smoke alarm 1 is a well-known product in the market and will not be elaborated here.)

[0030] Refer to Figures 2-3, the disassembly and assembly device 2 includes a hollow rod 21 fixedly connected to the bottom of the card seat 4. A conical block 22 is fixedly connected to the upper top of the smoke alarm 1. A sliding rod 23 is slidably connected to the side surface of the hollow rod 21. A first spring 24 is sleeved on the surface of the sliding rod 23. Two ends of the first spring 24 are respectively fixedly connected to the hollow rod 21 and the end of the sliding rod 23 away from the hollow rod 21. The other end of the sliding rod 23 is fixedly connected to a trapezoidal block 27. With the cooperation of the trapezoidal block 27 and the conical block 22, the disassembly and assembly between the smoke alarm 1 and the card seat 4 is facilitated, thus achieving the function of convenient disassembly and assembly. When the smoke alarm 1 needs to be installed and used, the card seat 4 is fixed on the wall through a screw 5, and the smoke alarm 1 is fixed on the surface of the card seat 4 through the disassembly and assembly device 2, thereby completing the installation of the smoke alarm 1. (The smoke alarm 1 is a well-known product in the market and will not be elaborated here). One end of the hollow rod 21 is fixedly connected to an airbag 28. The airbag 28 is arranged at one end of the hollow rod 21 close to the smoke alarm 1. Under the action of the airbag 28, when the smoke alarm 1 is installed, it will not directly hit one end of the hollow rod 21, avoiding the phenomenon of rigid contact. A rectangular groove 25 is formed on the surface of the hollow rod 21. A rectangular rod 26 is slidably connected inside the rectangular groove 25. One end of the rectangular rod 26 is fixedly connected to the upper top of the smoke alarm 1. With the cooperation of the rectangular groove 25 and the rectangular rod 26, the phenomenon that the smoke alarm 1 rotates during installation is avoided. A magnetic plate 29 is fixedly connected to the inner wall of the hollow rod 21. An iron sheet is fixedly connected to the upper top of the conical block 22. With the cooperation of the magnetic plate 29 and the iron sheet, the conical block 22 can be fixed inside the hollow rod 21. When the smoke alarm 1 needs to be installed, the conical block 22 is inserted into the hollow rod 21, and the rectangular rod 26 is inserted into the rectangular groove 25, so that the smoke alarm 1 will not rotate during installation, and then the trapezoidal block 27 is extruded to move to both sides. When the iron sheet on the upper top of the conical block 22 is attracted to the magnetic plate 29 and the conical block 22 is separated from the trapezoidal block 27, the trapezoidal block 27 moves towards the inside of the hollow rod 21 under the action of the first spring 24, thereby clamping the conical block 22 inside the hollow rod 21. Under the action of the airbag 28, when the smoke alarm 1 is installed, it will not directly hit one end of the hollow rod 21, avoiding the phenomenon of rigid contact. When the smoke alarm 1 is disassembled, the sliding rod 23 is pulled to both sides, so that the trapezoidal block 27 moves to both sides from the bottom of the conical block 22, and the smoke alarm 1 is pulled downwards, so that the iron sheet is separated from the magnetic plate 29, thereby disassembling the smoke alarm 1, thus achieving the function of convenient disassembly and assembly of the smoke alarm 1.

[0031] Refer to Figure 4, the disassembly device 3 includes an annular groove 31 formed on the surface of the smoke detector 1. A groove 32 is formed on the surface of the annular groove 31. The other side of the annular groove 31 is fixedly connected with a convex block 33. A clamping groove is formed in the inner wall of the convex block 33. A clamping ring 35 is fixedly connected inside the groove 32. The clamping ring 35 is a rubber ring. Under the action of the clamping ring 35 and the clamping groove, the smoke detector 1 can be disassembled, so as to facilitate the maintenance of the components inside the smoke detector 1. A magnetic block 36 is fixedly connected to the inner wall of the groove 32, and a magnetic block 36 is fixedly connected to the bottom of the convex block 33. Under the action of the positive extreme of one magnetic block 36 and the negative extreme of the other magnetic block 36, the convex block 33 can be firmly inserted into the groove 32. A clamping rod 34 is inserted into the side of the smoke detector 1, and the clamping rod 34 is inserted into the convex block 33. Under the action of the clamping rod 34, the convex block 33 can be fixed inside the groove 32, thus achieving a fixing effect. A second spring 37 is sleeved on the surface of the clamping rod 34. The two ends of the second spring 37 are respectively fixedly connected to the surface of the smoke detector 1 and the end of the clamping rod 34 away from the smoke detector 1. Under the action of the second spring 37, the clamping rod 34 is inserted into the convex block 33 in a self-locking state for fixing. When the smoke detector 1 is separated from the card seat 4, pull the clamping rod 34 outwards to separate the clamping rod 34 from the convex block 33, and separate the smoke detector 1 through the groove 32 to maintain the internal components. After the maintenance is completed, insert the convex block 33 into the groove 32 again. Under the action of the positive extreme of one magnetic block 36 and the negative extreme of the other magnetic block 36, the convex block 33 can be firmly inserted into the groove 32. After the magnetic blocks 36 are adsorbed together by magnetism, under the action of the second spring 37, the clamping rod 34 is inserted into the convex block 33 in a self-locking state for fixing, thus achieving a disassembly effect.

[0032] Working principle: When it is necessary to use the easily disassembled and assembled smoke detector 1, when it is necessary to install and use the smoke detector 1, the card holder 4 is fixed on the wall by screws 5, and the smoke detector 1 is fixed on the surface of the card holder 4 through the disassembly and assembly device 2, thus completing the installation of the smoke detector 1. (The smoke detector 1 is a well-known product in the market and will not be elaborated here.) When it is necessary to install the smoke detector 1, the conical block 22 is inserted into the interior of the hollow rod 21, and the rectangular rod 26 is inserted into the interior of the rectangular groove 25, so that the smoke detector 1 will not rotate during installation. Then, the trapezoidal block 27 is squeezed to move to both sides. When the iron sheet on the top of the conical block 22 is attracted to the magnetic plate 29 and the conical block 22 is separated from the trapezoidal block 27, the trapezoidal block 27 moves into the interior of the hollow rod 21 under the action of the first spring 24, thus clamping the conical block 22 inside the hollow rod 21. Under the action of the airbag 28, when the smoke detector 1 is installed, it will not directly impact one end of the hollow rod 21, avoiding the phenomenon of rigid contact. When disassembling the smoke detector 1, the slide rod 23 is pulled to both sides, so that the trapezoidal block 27 moves to both sides from the bottom of the conical block 22, and the smoke detector 1 is pulled downwards to separate the iron sheet from the magnetic plate 29, thus disassembling the smoke detector 1, thereby achieving the function of convenient disassembly and assembly of the smoke detector 1. When the smoke detector 1 is separated from the card holder 4, the latch 34 is pulled outwards to separate the latch 34 from the convex block 33, and the smoke detector 1 is separated through the groove 32 to repair the internal components. After the repair is completed, the convex block 33 is inserted into the interior of the groove 32 again. Under the action of the positive extreme of the magnetic block 36 and the negative extreme of another magnetic block 36, the convex block 33 can be firmly inserted into the interior of the groove 32. After the magnetic blocks 36 are attracted to each other under the action of magnetism, under the action of the second spring 37, the latch 34 is inserted into the interior of the convex block 33 in a self-locking state for fixation, thus achieving the function of disassembly.
