[0031] The present application provides a technical solution:

[0032] For example, Figures 1-5As shown, the aspirating smoke detector with positioning function in this embodiment includes a detector body 100 and a box body 110. The detector body 100 is provided with a fixing block 200. The left and right side walls of the fixing block 200 are provided with clamping grooves 201. The box body 110 is provided with a cavity 301. The lower end surface of the box body 110 is provided with a slot 302 for the fixing block 200 to extend into the cavity 301. The cavity 301 is provided with clamping plates 310 on the left and right sides of the slot 302. The cavity 301 is provided with a driving assembly on the left and right side walls. The driving assembly is used to drive one end of the clamping plate 310 to be clamped into the corresponding clamping groove 201. The front side of the cavity 301 is provided with a driving member. The driving member is used to drive one end of the two clamping plates 310 to be separated from the corresponding clamping groove 201.

[0033] In this embodiment, the upper end surface of the box body 110 extends outward to form a mounting portion 120. The mounting portion 120 is screwed into the area where it needs to be installed through a bolt 121. The fixing block 200 is fixedly installed on the detector body 100. By extending the upper end of the fixing block 200 out of the cavity 301 through the slot 302, the corresponding clamping plate 310 is moved by the driving assembly in the cavity 301, so that one end of the clamping plate 310 extends into the corresponding clamping groove 201, thereby achieving the installation of the fixing block 200 on the box body 110, i.e., the installation of the detector body 100. When the detector body 100 needs to be repaired or maintained, the two clamping plates 310 are driven by the driving member to be separated from the corresponding clamping groove 201, thereby releasing the installation of the fixing block 200 on the box body 110, i.e., the detector body 100 can be removed from the box body 110, thereby facilitating the maintenance and repair of the detector body by the staff and increasing the work efficiency of the staff.

[0034] In this embodiment, the detector body 100 adopts the structure disclosed in the patent with the publication number CN215427575U in the background art.

[0035] In this embodiment, the detector body 100 is further provided with an existing GPS locator, so that the aspirating smoke detector has a positioning function, i.e., when the detector body 100 detects a fire, the staff can quickly learn the location of the fire through the GPS locator, thereby improving the practicability of the aspirating smoke detector.

[0036] In actual use, the detector body 100 can be installed on the box body 110 through the driving assembly, and the installation of the detector body 100 on the box body 110 can be released through the driving member. Compared with the existing technology, when the staff repairs or maintains the detector body 100, the aspirating smoke detector does not need to disassemble and assemble the bolt 121 in sequence, thereby facilitating the maintenance and repair of the staff and improving the work efficiency of the staff.

[0037] As shown inFigures 1-4 As shown, in the embodiment, the upper end face of the clamping plate 310 is provided with a positioning block 320;

[0038] The pushing assembly comprises a mounting rod 330 provided on the positioning block 320 and facing the side wall of the cavity 301, the mounting rod 330 is provided with a baffle 331, and the side wall of the cavity 301 is provided with a spring 350, which is used to push the baffle 331 on the positioning block 320 to drive the clamping plates 310 to approach each other, so as to realize that one end of the clamping plate 310 is clamped in the corresponding clamping groove 201.

[0039] In the embodiment, through the arrangement of the positioning block 320, the mounting rod 330, the baffle 331 and the spring 350, the mounting rod 330 on the positioning block 320 is moved to the slot 302 by the spring 350 pushing the baffle 331, so that one end of the clamping plate 310 is clamped into the corresponding clamping groove 201, thereby realizing that the fixing block 200 is installed on the box body 110;

[0040] Among them, the baffle 331 is screw mounted on the mounting rod 330, and the mounting rod 330 is screw mounted on the positioning block 320, so that when the spring 350 pushes the baffle 331, the mounting rod 330 and the positioning block 320 can be moved to the slot 302, that is, the clamping plates 310 approach each other;

[0041] Among them, the side wall of the cavity 301 is screw mounted with a limiting column 360, one end of the mounting rod 330 extends out of the baffle 331, so that one end of the spring 350 is sleeved on the limiting column 360, and the other end of the spring 350 is sleeved on the mounting rod 330 and abuts against the baffle 331, so that the spring 350 is installed in the cavity 301, thereby better pushing the clamping plate 310 to move;

[0042] When actually used, the upper side of the cavity 301 is provided with a fixed groove 341 along the length direction thereof, and the upper end face of the positioning block 320 is fixedly installed with a clamping block 321 clamped into the fixed groove 341, so that when the spring 350 pushes the positioning block 320 to drive the clamping plate 310 to move, the clamping plate 310 can only slide horizontally along the fixed groove 341, so that the movement of the clamping plate 310 is better, thereby avoiding that the clamping plate 310 deviates when moving in the cavity 301, causing the clamping plate 310 to be unable to be clamped into the corresponding clamping groove 201, thereby affecting the installation of the fixing block 200 on the box body 110.

[0043] As Figures 1-4 As shown, in the embodiment, the side wall of the clamping plate 310 facing the slot 302 is provided with a guide inclined surface 311, and the left and right side walls of the fixing block 200 are provided with a matching inclined surface 202 matched with the corresponding guide inclined surface 311.

[0044] In the embodiment, the guide slope 311 and the matching slope 202 are arranged, so that when the fixed block 200 is inserted into the cavity 301 from the slot 302, the matching slope 202 on the fixed block 200 extrudes the guide slope 311 on the clamping plate 310, so that the clamping plates 310 are away from each other, at this time, the spring 350 is compressed, when the clamping groove 201 on the fixed block 200 moves to opposite to the clamping plate 310, the spring 350 resets and pushes the clamping plate 310 to move and clamp into the corresponding clamping groove 201, so that the fixed block 200 is installed on the box body 110, the installation is more convenient, and the practicality is stronger.

[0045] In order to avoid that the two springs 350 push the corresponding clamping plates 310 to be close to each other, so that the matching slope 202 on the fixed block 200 cannot better extrude the corresponding guide slope 311, the both ends of the clamping plate 310 are fixedly installed with the abutting blocks 430, when the spring 350 pushes the clamping plate 310 to be close to the slot 302, the corresponding abutting blocks 430 on the two clamping plates 310 abut each other, so that the distance between the two clamping plates 310 is always kept, and the matching slope 202 on the upper end of the fixed block 200 can better match with the corresponding guide slope 311, and the use effect is better.

[0046] As shown in Figures 1-5 In the embodiment, the mounting rod 330 between the baffle 331 and the clamping plate 310 is provided with the driving rod 400 on the front side of the cavity 301, and the first slope 401 is arranged at one end of the driving rod 400.

[0047] The driving member includes the mounting cylinder 410 arranged on the front side of the cavity 301, the rotatable rotating rod 420 arranged on the mounting cylinder 410 in the cavity 301, and the second slope 421 arranged at both ends of the rotating rod 420 and matched with the corresponding first slope 401, the rotating rod 420 rotates to drive the second slope 421 at both ends to extrude the first slope 401 on the corresponding driving rod 400, so that the two driving rods 400 are away from each other.

[0048] In the embodiment, the driving rod 400, the first slope 401, the mounting cylinder 410, the rotating rod 420, the second slope 421 and the mounting cylinder 410 are arranged, so that the rotating rod 420 is rotated in the cavity 301, and the second slope 421 at both ends of the rotating rod 420 is arranged to extrude the corresponding first slope 401, so that the driving rod 400 moves to the corresponding spring 350, thereby driving the positioning block 320 on the clamping plate 310 to move, the clamping plate 310 is separated from the corresponding clamping groove 201, and the installation of the fixed block 200 on the box body 110 is released, that is, the installation of the probe body 100 in the box body 110 is released.

[0049] The drive rod 400 is fixedly mounted on the mounting rod 330, so that the drive rod 400 can drive the mounting rod 330 on the positioning block 320 to move.

[0050] In actual use, the mounting cylinder 410 is mounted on the side wall of the cavity 301 via bearings, and the rotating rod 420 is fixedly mounted on the mounting cylinder 410. By driving the mounting cylinder 410 to rotate, the rotating rod 420 can be driven to rotate, thereby releasing the installation of the fixing block 200 in the box 110.

[0051] like Figures 1-5 As shown, in this embodiment, a limiting groove 501 is provided on the front side of the box body 110, and one end of the mounting cylinder 410 extends out of the box body 110. A circular plate 510 is provided on the extended end of the mounting cylinder 410, and a limiting block 511 that is inserted into the limiting groove 501 is provided on the side wall of the circular plate 510 facing the box body 110. A lever 512 is provided on the front side of the circular plate 510 near the edge.

[0052] In this embodiment, by setting up the limiting groove 501, the circular plate 510, the limiting block 511 and the lever 512, the circular plate 510 is fixedly installed on the protruding end of the mounting cylinder 410, and the lever 512 is fixedly installed on the circular plate 510. This allows the lever 512 to better start the rotation of the circular plate 510 and drive the mounting cylinder 410 to rotate, which is more convenient in practice and has a better effect in use.

[0053] In actual use, when the lever 512 drives the rotating rod 420 to rotate, when the second inclined surface 421 on the rotating rod 420 presses against the first inclined surface 401, and the driving rod 400 moves to its farthest end, it continues to drive the rotating rod 420 to rotate. This causes the second inclined surface 421 at both ends of the rotating rod 420 to fail to cooperate with the corresponding first inclined surface 401, thus affecting actual use. To prevent the second inclined surface 421 on the rotating rod 420 from failing to resist the first inclined surface 401 on the driving rod 400, By fixing a limiting block 511 on the circular plate 510, when the second inclined surface 421 on the rotating rod 420 pushes the first inclined surface 401 on the driving rod 400 to the maximum distance, the limiting block 511 abuts against the end of the limiting groove 501, so that the lever 512 cannot rotate on the driving circular plate 510, that is, the rotating rod 420 cannot rotate, thereby avoiding the second inclined surface 421 on the rotating rod 420 from not being able to cooperate with the first inclined surface 401 on the driving rod 400, which would affect the actual use.

[0054] Working principle: first, the box body 110 is installed in the area needing installation through the bolt 121 penetrating the mounting portion 120, and the fixing block 200 is installed on the detector body 100, at this time, the fixing block 200 is inserted into the cavity 301 from the notch 302 on the upper end, the installation of the detector body 100 on the box body 110 is realized, when the staff needs to maintain or maintain the detector body 100, the fixing block 200 can be taken off from the box body 110 by rotating the pull rod 512, that is, the detector body 100 is taken off, and the maintenance or maintenance is facilitated.

[0055] The basic principle, main characteristics and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
