Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a fire protection equipment testing instrument. Background Technology

[0002] Fire protection facilities refer to fixed facilities within a building, such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants. Automatic fire protection facilities are divided into electrical system automatic facilities and water system automatic facilities. Among them, fire alarms are alarms that are used to detect large amounts of smoke, heat, or other factors that may lead to a fire. They are generally installed in corridors, stairwells, and other frequently used areas. When a fire occurs, they can sound an alarm and flashing lights to alert people on the scene.

[0003] The prior art disclosure number CN219300264U discloses an IoT fire protection facility detection device, belonging to the field of fire protection equipment. It includes a mounting base and a gas alarm. Support plates are fixedly connected to the top and bottom of the mounting base. A screw is rotatably installed between the two support plates. An adjusting seat is threaded onto the screw. The gas alarm is mounted on the adjusting seat. A mounting groove is formed on one side of the adjusting seat. A mounting seat is fixedly connected to the back of the gas alarm. Snap-fit ​​grooves are formed on both sides of the mounting seat. Grooves are formed on both sides of the adjusting seat located in the mounting grooves. A spring is installed in each groove. A snap-fit ​​block adapted to the snap-fit ​​groove is fixedly connected to one end of the spring. A push block penetrating the adjusting seat is fixedly connected to one side of the snap-fit ​​block. Through the knob, screw, and adjusting seat, the position of the gas alarm can be adjusted without any tools, making operation convenient and labor-saving, and improving work efficiency.

[0004] With the above configuration, the existing detection equipment, by incorporating a mounting slot, mounting base, snap-fit ​​slot, spring, snap-fit ​​block, and push block, allows for quick installation of the gas alarm. Simply insert the mounting base on the back of the gas alarm into the mounting slot, and the spring pushes the snap-fit ​​block into the snap-fit ​​slot. Similarly, to remove the gas alarm, simply push the push block to remove the snap-fit ​​block from the snap-fit ​​slot. This facilitates installation and removal, improves maintenance efficiency, and streamlines the process. However, the existing detection equipment has the following drawbacks during operation:

[0005] The existing detection equipment requires two people to disassemble the gas alarm. One person pulls two push blocks while the other pulls the gas alarm, making disassembly very inconvenient and impossible for one person, wasting time and manpower. Utility Model Content

[0006] The present invention aims to provide a fire equipment testing instrument, which is mainly used to solve the technical problem that the existing technology requires two people to disassemble the gas alarm, which is very inconvenient.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A fire-fighting equipment testing instrument includes an adjusting base and a gas alarm. The adjusting base has a slot on its front side. A plug is fixedly connected to one side of the gas alarm and is inserted into the slot. The inner wall of the slot has symmetrical movable grooves. A limit rod is slidably connected inside the movable groove. A first spring is installed at one end of the inner wall of the slot, and the other end of the first spring abuts against one end of the limit rod. Symmetrical limit grooves are provided on both sides of the plug, and the limit rod is inserted into the limit groove. A sliding groove is provided on the inner wall of the movable groove, and a sliding plate is slidably connected to the inner wall of the sliding groove. The sliding plate is fixedly connected to the limit rod. A through hole is provided on the upper surface of the adjusting base, and a drive mechanism is installed inside the through hole.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the gas alarm needs to be disassembled, first rotate the rotating block adjustment drive mechanism to make the fixed rod push the slide plate to move. The slide plate drives the limit rod to compress the first spring, so that the limit rod is retracted into the movable groove and at the same time, the limit rod is disengaged from the limit groove. Then pull the gas alarm to pull it out to complete the disassembly.

[0011] 2. Beneficial effects:

[0012] Existing technology, through the design of a mounting slot, mounting base, snap-fit ​​groove, spring, snap-fit ​​block, and push block, allows for quick installation of the gas alarm. Simply insert the mounting base on the back of the gas alarm into the mounting slot, causing the spring to push the snap-fit ​​block into the snap-fit ​​groove. Disassembly is straightforward; simply push the push block to remove the snap-fit ​​block from the snap-fit ​​groove. This facilitates installation and removal, improves maintenance efficiency, and addresses a technical challenge. However, existing detection equipment requires two people to disassemble the gas alarm: one person pulls two push blocks, and the other... Disassembling a gas alarm is inconvenient for a single person, as it cannot be done alone and wastes time and manpower. This solution addresses this by using a sliding plate, threaded rod, threaded cylinder, rotating rod, first bevel gear, second bevel gear, and fixed rod. By rotating the rotating rod, the first bevel gear drives the second bevel gear to rotate, causing the threaded cylinder to rotate. This causes the threaded rod to move through the threaded cylinder, which in turn moves the fixed rod. The fixed rod then pushes the sliding plate, which in turn pushes the limit rod out of the limit groove, allowing the gas alarm to be disassembled. This method allows for disassembly by a single person, making disassembly very convenient, while also ensuring a very stable fixation of the gas alarm.

[0013] Preferably, the drive mechanism includes a rotating rod rotatably connected inside the through hole. The adjusting seat has a movable cavity connected to the through hole and a sliding groove. A first bevel gear is fixedly connected to one end of the rotating rod inside the movable cavity. A symmetrical threaded cylinder is movably connected to the inner wall of the movable cavity. A second bevel gear is fixedly connected to one end of the threaded cylinder, meshing with the first bevel gear. A threaded rod is threadedly connected inside the threaded cylinder, and a fixed rod is fixed to one end of the threaded rod. The fixed rod passes through the sliding groove and slides therewith. The end of the fixed rod away from the threaded cylinder abuts against the sliding plate. By setting up the drive mechanism, the limiting rod can be moved. When the rotating block drives the rotating rod to rotate, the engagement between the first and second bevel gears causes the fixed rod to push the sliding plate to move. The sliding plate then pushes the limiting rod to move, causing the limiting rod to disengage from the limiting groove, facilitating the disassembly of the gas alarm.

[0014] Preferably, the front of the adjusting seat has a horizontal groove and a fixed groove. The horizontal groove is connected to the movable groove. A second spring is fixedly connected inside the fixed groove. A slide rod is fixedly connected to the other end of the second spring. The slide rod is slidably connected to the fixed groove. A pull block is rotatably connected to the end of the slide rod away from the second spring. A horizontal block is slidably connected to the inner wall of the horizontal groove. The horizontal block is fixedly connected to the pull block. By setting the second spring and the horizontal block, the first spring can be replaced. Pulling the pull block causes the horizontal block to move with the pull block. The slide rod moves with the pull block and stretches the second spring, causing the horizontal block to disengage from the horizontal groove. Then, the first spring can be removed and replaced. Finally, the horizontal block is inserted into the horizontal groove to complete the replacement.

[0015] Preferably, a guide rod is fixed to the inner wall of the slot, and a guide groove is formed on the side of the insert block away from the gas alarm, with the guide rod inserted into the guide groove. By setting the guide rod and guide groove, it is possible to prevent the insert block from being installed backwards, thus avoiding unstable fixation of the gas alarm.

[0016] Preferably, the threaded rod and the fixed rod move the same distance as the slide plate. This prevents the threaded rod from disengaging from the fixed rod and avoids the limit rod from failing to disengage from the limit groove.

[0017] Preferably, the side of the limiting rod located at the opening has a slope. This makes the installation of the gas alarm with the insert block more convenient.

[0018] Preferably, a rotating block is fixedly connected to the end of the rotating rod away from the first bevel gear, and the outer wall of the rotating block has anti-slip texture. This facilitates the rotation of the rotating rod and increases the friction between the fingers and the rotating block to prevent slippage. Attached Figure Description
