Description

Technical Field

[0001] The utility model relates to the technical field of smoke sensors, in particular to a smoke sensor for fire fighting. Background Art

[0002] Smoke sensors, also known as smoke alarms or smoke detectors, can detect smoke generated during fires. They use photoelectric smoke sensors inside and can be widely used in shopping malls, hotels, stores, warehouses, computer rooms, residences and other places for fire safety detection.

[0003] Chinese patent publication number CN219177422U, publication time 20230613, discloses a fire smoke sensor that is easy to install, including a sensor body, a fixed plate is fixedly installed on the rear side of the sensor body, a fixed seat is provided on the rear side of the fixed plate, push rods penetrating into the interior are provided on both sides of the fixed seat, a spring 1 is sleeved on the surface of the push rod, one end of the push rod is fixedly connected to a connecting block penetrating into the surface of the fixing seat, one end of the connecting block is fixedly connected to a male buckle, a female buckle is fixedly installed inside the fixed plate, and a rod body 2 is fixedly installed on the rear side of the fixed plate.

[0004] The existing fire smoke sensor such as the above-mentioned first aligns the fixing seat with the fixing plate, and then pushes the push rod to one side to extend the spring 1, thereby driving the male buckle and the female buckle to engage with each other. After the engagement is completed, the force applied to the push rod is released, and the male buckle and the female buckle are tightly engaged through the contraction elasticity of the spring 1. In the specific implementation process, once the shell loses the restraining force of the plug block, it will fall straight down. Therefore, during the disassembly and assembly of the shell and the mounting seat, the operator is required to hold the device body while operating the push rod. There are multiple groups of push rods, which makes the overall operation more inconvenient. Therefore, it is urgent to propose a corresponding fire smoke sensor to solve the above problems.

The interference fit ensures the stability of the position of the rubber block itself. The rubber block will abut against the outer wall of the locking rod, thereby limiting the loosening of the locking rod through friction, thereby improving the stability of the fire smoke sensor.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A smoke sensor for fire protection comprises a mounting seat 1 and a shell 2, a matching seat 7 is fixedly mounted on the top of the shell 2, the matching seat 7 is plugged into the mounting seat 1, a limiting component for axially limiting the matching seat 7 is arranged between the matching seat 7 and the mounting seat 1, a telescopic block 11 is slidably connected to the inner surface wall of the matching seat 7, a vertical plate 12 is fixedly connected to the outer surface wall of the telescopic block 11, and a spring 13 is fixedly mounted between the vertical plate 12 and the inner surface wall of the matching seat 7, a pushing component for pushing the telescopic block 11 is arranged between the mounting seat 1 and the vertical plate 12, and a limiting seat 10 for limiting the telescopic block 11 is fixedly connected to the inner surface wall of the mounting seat 1;

[0025] After installing the mounting base 1 on the external wall and completing the connection of the lines, the matching base 7 is coupled to the mounting base 1. The axial position of the matching base 7 can be limited by the cooperation of the clamping edge 8 and the convex strip 9, so that only the shell 2 and the matching base 7 need to be pushed upwards. As the telescopic block 11 slides and cooperates with the sliding section 1001, the vertical plate 12 compresses the spring 13 until the telescopic block 11 is coupled to the inside of the notch 1002, thereby realizing the installation of the smoke sensor. The subsequent operator simultaneously engages with the two sets of pressing plates 6 by hand and presses them. The vertical plate 12 compresses the spring 13 and drives the telescopic block 11 to disengage from the notch 1002, thereby realizing the rapid separation of the shell 2. There is no need to lift up the shell 2, and the overall operation is relatively convenient, thereby improving the convenience of using the fire smoke sensor.

[0026] Specifically, Figure 2 and Figure 4 As shown, a connecting piece 3 is fixedly installed on the outer wall of the mounting base 1, and a locking rod 4 is screwed and connected inside the connecting piece 3. A rubber block 5 is interference-fitted inside the connecting piece 3, and the rubber block 5 abuts against the outer wall of the locking rod 4. The mounting base 1 completes the fixing of the wall through the connecting piece 3 and the locking rod 4, after which the rubber block 5 can be interference-fitted into the inside of the connecting piece 3. The interference fit ensures that the position of the rubber block 5 itself is stable. The rubber block 5 will abut against the outer wall of the locking rod 4, so that the loosening of the locking rod 4 can be limited by friction, thereby improving the stability of the fire smoke sensor.

[0027] Specifically, Figure 2 and Figure 3 As shown, the limit seat 10 includes a sliding section 1001 and a missing groove 1002, and the sliding section 1001 is slidably matched with the open end of the telescopic block 11. As the telescopic block 11 slides with the sliding section 1001, the vertical plate 12 compresses the spring 13 until the telescopic block 11 is combined with the inside of the missing groove 1002, thereby realizing the installation of the smoke sensor. The pushing component includes a pressing plate 6 that is slidably matched with the inner surface wall of the matching seat 7. The pressing plate 6 is fixedly connected to the vertical plate 12, and the outer wall of the pressing plate 6 is engaged with the inner surface wall of the mounting seat 1. The operator simultaneously engages with the two groups of pressing plates 6 by hand and presses them. The vertical plate 12 compresses the spring 13 and drives the telescopic block 11 to disengage from the missing groove 1002. The limit assembly includes a convex strip 8 and a card edge 9 that are engaged and connected. The convex strip 8 and the card edge 9 are respectively fixedly connected to the matching seat 7 and the mounting seat 1. The axial position of the matching seat 7 can be limited by the cooperation of the card edge 8 and the convex strip 9, so that the axial position of the shell 2 and the matching seat 7 will not be offset.

[0028] Working principle: Install the mounting base 1 on the external wall. After completing the line connection, combine the matching base 7 to the mounting base 1. The axial position of the matching base 7 can be limited by the combination of the clamping edge 8 and the convex strip 9, so that only the housing 2 and the matching base 7 need to be pushed upward. As the telescopic block 11 and the sliding section 1001 slide and cooperate, the vertical plate 12 compresses the spring 13 until the telescopic block 11 is combined with the inside of the missing groove 1002, thereby realizing the installation of the smoke sensor. The subsequent operator combines the hands with the two sets of pressing plates 6 at the same time and presses them. The vertical plate 12 compresses the spring 13 while bringing The movable telescopic block 11 is disengaged from the notch 1002, thereby realizing the rapid separation of the shell 2, without the need to lift the shell 2, and the overall operation is relatively convenient, thereby improving the convenience of using the fire smoke sensor. The mounting base 1 is fixed to the wall through the connecting piece 3 and the locking rod 4, after which the rubber block 5 can be interference fit into the inside of the connecting piece 3. The interference fit method ensures that the position of the rubber block 5 itself is stable. The rubber block 5 will abut against the outer wall of the locking rod 4, so that the loosening of the locking rod 4 can be limited by friction, thereby improving the stability of the fire smoke sensor.
