[0021] The present invention is described below in conjunction with the accompanying drawings and embodiments, and the following embodiments are used to explain the optimal effects of the present invention. Example

[0022] like Figure 1-5As shown, the photoelectric smoke fire detection alarm device comprises an adjustment mechanism 1 and a fixing plate 101, a disassembly mechanism 2 is arranged at the bottom of the adjustment mechanism 1, a threaded rod 102 is fixedly connected to the bottom of the fixing plate 101, a mounting platform 103 is threadedly connected to the outer surface of the threaded rod 102, an adjustment block 111 is contacted at the bottom of the mounting platform 103, an adjustment groove 110 is arranged inside the adjustment block 111, and a locking groove 104 is arranged inside the adjustment groove 110;

[0023] A card slot 105 is provided at the bottom of the locking slot 104, and a fixing rod 108 is fixedly connected to the bottom of the mounting platform 103. A card plate 106 is rotatably connected to the bottom of the fixing rod 108, and the outer surface of the card plate 106 is adapted to the inner wall of the card slot 105. The adjustment block 111 is pulled downward, and when the adjustment block 111 moves downward, the slide plate 107 will be pulled downward, and the card plate 106 will be disengaged from the card slot 105. At the same time, the spring 109 is squeezed, and then the adjustment block 111 and the alarm are moved. After moving to the appropriate position, the adjustment block 111 is rotated again so that the adjustment block 111 is rotated around the fixing rod 108 as the center, so that the adjustment range becomes larger, and the position of the alarm body can be flexibly adjusted. The position of the alarm body can be adjusted separately while keeping the mounting base stationary. The operation is simple, and there is no need to disassemble and reinstall after the installation position is wrong.

[0024] The outer surface of the fixing rod 108 is slidably connected to the inner wall of the adjusting slot 110 , the outer surface of the fixing rod 108 is slidably connected to the slide plate 107 , and the outer surface of the fixing rod 108 is sleeved with a spring 109 .

[0025] The top of the spring 109 is fixedly connected to the bottom of the slide plate 107 , the bottom of the spring 109 is fixedly connected to the top of the clamping plate 106 , and the top of the slide plate 107 contacts the inner wall of the top of the locking groove 104 .

[0026] The disassembly mechanism 2 includes a mounting opening 201 opened inside the adjustment block 111 . A mounting groove 202 is opened inside the adjustment block 111 . There are two mounting grooves 202 in total. The two mounting grooves 202 are symmetrically arranged with the adjustment block 111 as the center.

[0027] The two mounting grooves 202 contain the same parts. The inner wall of the mounting groove 202 is slidably connected to a push plate 204, and a connecting plate 205 is fixedly connected to the bottom of the push plate 204. The bottom of the connecting plate 205 is fixedly connected to an alarm. The alarm is rotated to the right. When the alarm moves to the right, the connecting plate 205 and the push plate 204 are simultaneously driven to move. Because the push plate 204 is clamped with the extrusion plate 206 through the clamping block 210, the extrusion plate 206 is driven to move when the push plate 204 moves to the right. The movement of the extrusion plate 206 drives the movable rod 208 to move, which drives the sliding plate 207 to move, and when it moves to the exit of the mounting port 201, the alarm is pulled downward, so that the push plate 204 is disengaged from the adjustment block 111, thereby facilitating the installation and disassembly of the alarm, and solving the problem that the alarm is inconvenient to install and disassemble for maintenance when in use.

[0028] The top of the push plate 204 is fixedly connected with a clamping block 210 , and the top of the clamping block 210 contacts the extrusion plate 206 . The top of the clamping block 210 penetrates the extrusion plate 206 and extends to the inside. The outer surface of the extrusion plate 206 is slidably connected with the inner wall of the installation groove 202 .

[0029] The inner wall of the adjustment block 111 is provided with a sliding groove 203, the top of the extrusion plate 206 is fixedly connected with a movable rod 208, the outer surface of the sliding groove 203 is slidably connected with a sliding plate 207, and the top of the movable rod 208 penetrates the sliding plate 207 and extends to the outside.

[0030] A second spring 209 is sleeved on the outer surface of the movable rod 208 . The top of the second spring 209 is fixedly connected to the bottom of the sliding plate 207 , and the bottom of the second spring 209 is fixedly connected to the top of the extrusion plate 206 .

[0031] A specific application of this embodiment is: the staff first fixes the fixing plate 101 in the specified position, and then rotates the mounting platform 103 to the bottom of the fixing plate 101. When the alarm position needs to be adjusted, the adjusting block 111 is pulled downward. When the adjusting block 111 moves downward, the sliding plate 107 will be pulled downward, and the card plate 106 will be disengaged from the card slot 105, and the spring 109 will be squeezed at the same time. Then the adjusting block 111 and the alarm are moved. After moving to the appropriate position, the adjusting block 111 is rotated again so that the adjusting block 111 is rotated around the fixing rod 108 as the center, so that the adjustment range becomes larger, and the position of the alarm body can be flexibly adjusted. The position of the alarm body can be adjusted separately while keeping the mounting base stationary. The operation is simple, and there is no need to disassemble and reinstall after the installation position is wrong. When the alarm needs to be repaired, the alarm is pushed upward, and the connecting part is driven when the alarm moves upward. The plate 205 moves upward, and then pushes the push plate 204 and the extrusion plate 206 upward through the connecting plate 205 until they reach the top of the installation groove 202, and squeezes the spring 209, and drives the movable rod 208 to move upward while the extrusion plate 206 moves upward, and then the alarm is rotated to the right. When the alarm moves to the right, the connecting plate 205 and the push plate 204 are simultaneously driven to move. Because the push plate 204 is connected to the extrusion plate 206 through the clamping block 210, the extrusion plate 206 will be driven to move when the push plate 204 moves to the right, and the movable rod 208 will be driven to move through the movement of the extrusion plate 206, so that the sliding plate 207 is driven to move, and when it moves to the exit of the installation port 201, the alarm is pulled downward, so that the push plate 204 is disengaged from the adjustment block 111, thereby facilitating the installation and disassembly of the alarm, and solving the problem that the alarm is inconvenient to install and disassemble for maintenance when in use.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation. For ordinary technicians in the field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
