Description

Technical Field

[0001] This utility model relates to the field of automatic detection technology for smoke alarms, and in particular to an automatic detection gas injection device for smoke alarms. Background Technology

[0002] The automatic detection gas injection device for smoke detectors simulates a real fire smoke scenario by injecting a certain concentration and amount of smoke gas into the space where the smoke detector is located. It can accurately detect the response capability of the smoke detector to different concentrations of smoke and determine whether it can issue an alarm in time within the set smoke concentration threshold, so as to ensure a rapid response in the event of an actual fire.

[0003] When testing a smoke detector, the detector is first placed in a designated location within the testing cabinet. Then, the smoke generator inside the cabinet simulates smoke gas, causing the detector's sensors to react to this gas. The device can also record relevant data for each gas injection test, such as injection time, gas concentration, and the detector's response. It can also generate a test report for easy viewing and archiving by management personnel.

[0004] However, considering that the current technology for testing smoke detectors usually requires manual placement of the smoke detectors in the testing environment, the process is cumbersome and inefficient. In particular, when multiple smoke detectors need to be fixed or deactivated, the installation and removal of multiple smoke detectors need to be repeated multiple times, which is especially time-consuming when testing a large number of smoke detectors and will greatly affect the testing efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic smoke alarm detection and gas injection device, which aims to solve the problem that in the prior art, smoke alarm detection requires manual placement in the detection environment, which is cumbersome and inefficient. In particular, when fixing or deactivating multiple smoke alarms, repeated installation and disassembly operations are required, which is extremely time-consuming when detecting a large number of smoke alarms and affects detection efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic gas injection detection device for a smoke alarm includes a detection cabinet. A fixed plate is inserted into the top of the inner surface of the detection cabinet. A traction rod is elastically connected to the inner surface of the fixed plate via a spring. A hinge rod is hinged to the inner surface of the traction rod. A clamp is hinged to the right side of the outer surface of the hinge rod. The outer surface of the clamp is slidably connected to the inner surface of the fixed plate. A positioning seat is fixedly connected to the top of the outer surface of the fixed plate.

[0008] A smoke detector is inserted into the top of the outer surface of the positioning seat, and a retaining ring is fixedly connected to the bottom of the outer surface of the smoke detector. The outer surface of the clamp is engaged with the inner surface of the retaining ring, and the fixing plate is provided with a fixing component.

[0009] The fixing component includes a plug-in plate and a pressing block. The top of the outer surface of the plug-in plate is fixedly connected to the bottom of the outer surface of the fixing plate, and the outer surface of the plug-in plate is plugged into the top of the inner surface of the testing cabinet.

[0010] The front end of the outer surface of the testing cabinet is hinged to a cabinet door, the front end of the outer surface of the pressing block is fixedly connected to the top of the outer surface of the cabinet door, and the rear end of the outer surface of the pressing block is in contact with the front end of the outer surface of the fixing plate.

[0011] A handle is fixedly connected to the front end of the outer surface of the fixed plate. An operating rod is slidably connected through the inner surface of the handle. A plate body is fixedly connected to the rear end of the outer surface of the operating rod. The outer surface of the plate body is slidably connected along the front end of the inner surface of the fixed plate.

[0012] The front end of the outer surface of the traction rod is fixedly connected to a traction block, the rear end of the outer surface of the plate is in contact with the front end of the outer surface of the traction block, and the front end of the outer surface of the traction rod is through and slidably connected to the inner surface of the plate.

[0016] Both the hinge rod and the clamp are provided in two sets.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, through the synergistic action of components such as a fixing plate, a traction rod, a hinge rod, and clamps, allows multiple clamps to be opened simultaneously by simply pushing the traction rod when placing a smoke alarm. After inserting the alarm, releasing the traction rod causes the clamps to automatically retract and complete the fixation. This enables the quick and stable fixation of smoke alarms in the same row, greatly improving detection efficiency and simplifying the operation process.

[0019] 2. This utility model, through the interaction of the handle, operating lever and plate, enables the simultaneous control of multiple rows of smoke alarms. By pushing the two sets of operating levers, the plate moves, allowing the plate to simultaneously drive multiple sets of traction rods to control the clamps in multiple rows. This allows for unified and rapid operation of multiple clamps, reducing the time required to deactivate smoke alarms one by one. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 5 - Figure 6The present invention provides an embodiment of an automatic detection and gas injection device for a smoke alarm, comprising a detection cabinet 1, a fixing plate 5 inserted into the top of the inner surface of the detection cabinet 1, so that the fixing plate 5 can be inserted into the top of the inner surface of the detection cabinet 1, and a traction rod 8 elastically connected to the inner surface of the fixing plate 5 by a spring 14, so that the traction rod 8 can always move outward without being affected by external force.

[0030] The inner surface of the traction rod 8 is hinged with a hinge rod 13, so that when the traction rod 8 moves laterally, it can drive the hinge rod 13 to move together. The right side of the outer surface of the hinge rod 13 is hinged with a clamp 12, so that when the hinge rod 13 moves, it can drive the clamp 12 to move laterally due to the hinge. The outer surface of the clamp 12 is slidably connected to the inner surface of the fixing plate 5, so that the clamp 12 can move laterally along the inner surface of the fixing plate 5.

[0031] A positioning seat 11 is fixedly connected to the top of the outer surface of the fixing plate 5. The top of the outer surface of the fixing plate 5 provides a fixed support for the positioning seat 11. A smoke alarm 6 is inserted into the top of the outer surface of the positioning seat 11, so that the smoke alarm 6 can be accurately positioned in a designated position by inserting into the positioning seat 11. A retaining ring 17 is fixedly connected to the bottom of the outer surface of the smoke alarm 6, so that when the retaining ring 17 is fixed, it can drive the smoke alarm 6 to be fixed in a designated position together.

[0032] Both the hinge rod 13 and the clamp 12 are provided in two sets. When the two sets of hinge rods 13 are moved by the traction rod 8, the two sets of clamps 12 can be opened and closed due to the hinge. The smoke alarm 6 can be more stably fixed on the fixed plate 5 under the clamping of the two sets of clamps 12. The outer surface of the clamp 12 is engaged with the inner surface of the retaining ring 17, so that the retaining ring 17 can be fixed in the designated position under the clamping of the two sets of clamps 12.

[0033] The fixing plate 5 is equipped with a fixing component, which enables the fixing plate 5 to be always kept in a designated position after it is inserted into the top of the inner surface of the inspection cabinet 1.

[0034] Reference Figure 2 - Figure 4 The fixing component includes a plug-in plate 7 and a pressing block 4. The top of the outer surface of the plug-in plate 7 is fixedly connected to the bottom of the outer surface of the fixing plate 5, so that when the fixing plate 5 is inserted into the top of the inner surface of the testing cabinet 1, it can prevent vertical movement under the action of the fixing plate 5. The outer surface of the plug-in plate 7 is inserted into the top of the inner surface of the testing cabinet 1, so that when the fixing plate 5 is inserted, the plug-in plate 7 is simultaneously inserted into the top of the inner surface of the testing cabinet 1.

[0035] The front end of the outer surface of the testing cabinet 1 is hinged with a cabinet door 2, which prevents smoke from drifting outside the testing cabinet 1 when the testing is being performed. The front end of the outer surface of the pressing block 4 is fixedly connected to the top of the outer surface of the cabinet door 2, so that the pressing block 4 can move together when the cabinet door 2 is opened and closed. The rear end of the outer surface of the pressing block 4 is in contact with the front end of the outer surface of the fixing plate 5, so that when the cabinet door 2 is closed, the fixing plate 5 will not move laterally due to the contact between the rear end of the pressing block 4 and the front end of the fixing plate 5, thus fixing the fixing plate 5 inside the testing cabinet 1. An observation window is provided on the cabinet door 2 to facilitate observation of the testing situation inside the testing cabinet 1.

[0036] Reference Figure 3 - Figure 5 A handle 9 is fixedly connected to the front end of the outer surface of the fixed plate 5 to facilitate the operation of the operating lever 10. The operating lever 10 is slidably connected through the inner surface of the handle 9, allowing the operating lever 10 to move laterally along the inner surface of the handle 9 and also laterally along the front end of the inner surface of the fixed plate 5. A plate body 16 is fixedly connected to the rear end of the outer surface of the operating lever 10, so that the operating lever 10 can move the plate body 16 together when it moves laterally. The outer surface of the plate body 16 is slidably connected along the front end of the inner surface of the fixed plate 5, allowing the plate body 16 to move laterally along the front end of the inner surface of the fixed plate 5.

[0037] Reference Figures 1-2 , Figure 5 The front end of the outer surface of the traction rod 8 is fixedly connected to the traction block 15, so that when the traction block 15 moves laterally, it can drive the traction rod 8 to move together. The rear end of the outer surface of the plate 16 is in contact with the front end of the outer surface of the traction block 15, so that when the plate 16 moves laterally, it can drive the traction block 15 to move together due to the contact connection with the traction block 15. The front end of the outer surface of the traction rod 8 is through and slidably connected to the inner surface of the plate 16, so that when the traction rod 8 moves laterally, it will not drive the plate 16 to move together.

[0038] One end of the spring 14 is fixedly connected to the front of the inner surface of the fixed plate 5, and the other end of the spring 14 is fixedly connected to the outer surface of the traction rod 8, so that the traction rod 8 can move outward under the action of the elastic force of the spring 14 when the traction rod 8 is not pushed. A smoke generator 3 is fixedly connected to the bottom of the inner surface of the detection cabinet 1, so that the smoke generator 3 can simulate the effect of a real fire smoke scene.

[0039] Working principle: When using the device, first pull the fixed plate 5 out of the testing cabinet 1, then flip the fixed plate 5 and push the front end of the traction rod 8 so that it simultaneously drives the two sets of hinge rods 13 to open the two sets of clamps 12 outward. The fixed plate 5 is provided with a row of hinge rods 13 and clamps 12 so that when the traction rod 8 is pushed, multiple sets of clamps 12 can be opened at the same time. Then, insert the smoke alarm 6 into the positioning seat 11 on the fixed plate 5, then release the traction rod 8 so that it moves outward to reset due to the force of the spring 14, and the clamps 12 are pulled inward by the hinge rods 13 so that the clamps 12 clamp and fix the smoke alarm 6 on the fixed plate 5. Then, insert the fixed plate 5 into the top of the inner surface of the testing cabinet 1, close the cabinet door 2, start the smoke generator 3, and test the smoke alarm 6.

[0040] When it is necessary to place and remove multiple rows of smoke detectors 6 at the same time, first hold the handle 9 and the operating lever 10, and then simultaneously grip both components. This will cause the operating lever 10 to move the plate 16 backward, and also move the traction blocks 15 on the multiple sets of traction rods 8 together. This will cause the multiple sets of traction rods 8 to simultaneously open the multiple rows of clamps 12, thereby achieving the effect of placing and removing multiple rows of smoke detectors 6 at the same time by controlling the multiple rows of clamps 12 simultaneously.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
