Description

Technical Field

[0001] This utility model relates to the field of smoke sensor technology, and more specifically, to a push-pull type smoke sensor. Background Technology

[0002] A smoke sensor is a device used to detect smoke in the early stages of a fire and issue an alarm. Due to its high sensitivity and fast response, it is widely used in shopping malls, hotels, warehouses, computer rooms, residences and other places to effectively protect people's lives and property. In order to further ensure the detection accuracy and operational stability of the smoke sensor, it is necessary to maintain and inspect it regularly. Therefore, it is necessary to design a push-pull smoke sensor to enable quick disassembly and installation of the sensor, improve maintenance efficiency, reduce operation difficulty, and facilitate daily management and replacement.

[0003] In the prior art, patent application number 202321867098.1 discloses a push-pull smoke sensor, including a sensor body, a base, a connecting groove, a connecting tongue, and the sensor body itself. The sensor body slides along a first direction on a second side wall of the base, allowing the connecting tongue to extend into the connecting groove along the first direction, thus connecting the sensor body to the base and completing the connection between the sensor body and the base. However, during installation, this push-pull smoke sensor relies on the cooperation of the connecting tongue and the connecting groove. This connection method lacks an effective locking and reinforcement mechanism, easily leading to insufficient tightness or even loosening, thus affecting the overall stability and reliability of the installation and reducing the safety and robustness of the device during long-term use.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a push-pull smoke sensor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A push-pull smoke sensor includes: a mounting bracket; a smoke detection component disposed inside the mounting bracket and cooperating with the mounting bracket; and a push-pull disassembly mechanism disposed between the mounting bracket and the smoke detection component, which enables quick disassembly and connection between the mounting bracket and the smoke detection component, facilitating maintenance and replacement of the smoke detection component.

[0008] Furthermore, in order to install the push-pull smoke sensor on the wall, the mounting bracket can be installed on the wall with the cooperation of bolts and threaded holes to facilitate subsequent smoke detection. The mounting bracket includes: a push-pull groove, which is opened in the inner wall of the mounting bracket and is set to cooperate with the smoke detection component; and threaded holes, which are opened at the four corners of the top of the mounting bracket.

[0009] Furthermore, to achieve smoke detection and alarm, the smoke sensor body monitors the smoke concentration in the surrounding air in real time. When excessive smoke is detected, the smoke sensor body transmits an electrical signal to the circuit board. After processing the signal, the circuit board triggers the alarm to alert personnel. The smoke detection component includes: a push-pull plate, located inside the push-pull groove and fitted with a mounting bracket; baffles, symmetrically arranged at one end of the push-pull plate and fitted with the mounting bracket; a push-pull handle, located between the two baffles at the bottom of the push-pull plate; a circuit board, extending through the bottom of the push-pull plate; the smoke sensor body, located on one side of the bottom of the circuit board; an alarm, located on the other side of the bottom of the circuit board; a battery, located on one side of the smoke sensor body; a filter housing, located on the outer bottom of the push-pull plate; and a locking block, located at the top of the push-pull plate.

[0010] Furthermore, to achieve rapid disassembly and installation of the smoke detection component, the connecting rod and the sliding column moving within the groove ensure that the locking block is firmly held by two sets of clamping blocks, guaranteeing that the smoke detection component can be quickly fixed in the mounting frame. Simultaneously, it can be easily released when disassembly is required, improving overall operational efficiency and ease of use. The push-pull disassembly mechanism includes a connecting frame located on the inner wall of one end of the mounting frame. Inside the connecting frame is a movable block that cooperates with it. One side of the movable block has a movable column that penetrates the connecting frame, and the other side of the movable block is connected to the connecting frame. The spring is connected to the first part; the top of the moving block has a groove, and a sliding column that cooperates with it is set inside the groove. The top of the sliding column is fitted with a connecting rod that is connected to the connecting frame; the top of the sliding column is provided with a connecting block that is connected to the moving column and cooperates with the connecting frame. Both ends of the connecting block are provided with clamping blocks that are connected to it, and the locking block is located between the two sets of clamping blocks; the bottom of the other end of the mounting frame is provided with a stabilizing and reinforcing component that cooperates with the push-pull handle; the cross-section of the locking block is a trapezoidal structure, and the shape formed by the two sets of clamping blocks is matched with the shape of the locking block; the cross-section of the groove is a hexagonal heart structure.

[0011] Furthermore, to assist in the positioning and fixation of the smoke detection component, the fixing block engages with the push-pull handle under the action of the moving handle and the elastic force of the two springs, further ensuring the stable installation of the smoke detection component and enhancing the stability of the overall structure. Even under vibration or slight impact, it can maintain a good fixed state, effectively preventing the risk of accidental triggering or equipment falling off. The stabilizing and reinforcing component includes a hollow limiting frame set at the bottom of the other end of the mounting bracket. The hollow limiting frame is symmetrically equipped with two springs connected to the mounting bracket. The bottom of the two sets of springs is located inside the push-pull handle, and the top of the fixing block is located on the side away from the connecting frame, with a moving handle penetrating through the hollow limiting frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated arrangement of the mounting bracket, smoke detection component, and push-pull disassembly mechanism, not only enables smoke detection and alarm, but also allows for the rapid installation and disassembly of the smoke detection component, improving maintenance efficiency, extending service life, and preventing loose connections. This ensures the stability and reliability of the overall installation and enhances the safety and robustness of the push-pull smoke sensor during long-term use.

[0014] 2. Through the push-pull disassembly mechanism, the connecting rod and the sliding column move together in the slide groove, so that the card block is firmly clamped by two sets of clamping blocks, ensuring that the smoke detection component can be quickly fixed in the mounting frame. At the same time, it can be easily released when disassembly is required, improving the overall operating efficiency and ease of use.

[0015] 3. Through the stabilizing and reinforcing components, the fixed block can be engaged with the push-pull handle under the combined action of the moving handle and the spring force, further ensuring the stable installation of the smoke detection component and enhancing the stability of the overall structure. Even under vibration or slight impact, it can maintain a good fixed state, effectively preventing the risk of false triggering or equipment falling off. Attached Figure Description

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a push-pull type smoke sensor is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, the push-pull smoke sensor according to an embodiment of the present utility model includes: a mounting bracket 1; a smoke detection component 2, which is disposed inside the mounting bracket 1 and cooperates with the mounting bracket 1; and a push-pull disassembly mechanism 3, which is disposed between the mounting bracket 1 and the smoke detection component 2. The push-pull disassembly mechanism 3 enables quick disassembly and connection between the mounting bracket 1 and the smoke detection component 2, facilitating the maintenance and replacement of the smoke detection component 2.

[0030] In one embodiment, the mounting bracket 1 includes: a push-pull groove 101, which is formed on the inner wall of the mounting bracket 1 and is configured to cooperate with the smoke detection component 2; and threaded holes 102, which are formed at the four corners of the top of the mounting bracket 1; the mounting bracket 1 can be installed on the wall by the cooperation of the bolts and the threaded holes 102, which facilitates subsequent smoke detection.

[0031] In one embodiment, the smoke detection component 2 includes: a push-pull plate 201 disposed inside the push-pull groove 101 and cooperating with the mounting bracket 1; baffles 202 symmetrically disposed at one end of the push-pull plate 201 and cooperating with the mounting bracket 1; a push-pull handle 203 disposed between the two sets of baffles 202 and located at the bottom of the push-pull plate 201; a circuit board 204 extending through the bottom end of the push-pull plate 201; a smoke sensor body 205 disposed on one side of the bottom end of the circuit board 204; and an alarm. The device 206 is located on the other side of the bottom of the circuit board 204; the battery 207 is located on one side of the smoke sensor body 205; the filter shell 208 is located on the bottom outer side of the push-pull plate 201; and the locking block 209 is located on the top of the push-pull plate 201. Under the function of real-time monitoring of the smoke concentration in the surrounding air by the smoke sensor body 205, when the smoke exceeds the standard, the smoke sensor body 205 transmits an electrical signal to the circuit board 204. After processing the signal, the circuit board 204 triggers the alarm 206 to sound an alarm and remind personnel to pay attention.

[0032] Furthermore, it should be noted that the smoke sensor body 205 and the alarm 206 transmit electrical signals through the lines on the circuit board 204. When the smoke sensor detects smoke, it triggers the alarm 206 to sound an alarm. In specific applications, the smoke sensor body 205 can be an ionization smoke sensor that uses trace amounts of radioactive materials to ionize oxygen and nitrogen molecules in the air, forming a weak current. When smoke particles enter, they change this current and are thus detected. The smoke sensor body 205, the alarm 206, and the circuit board 204 are existing technologies and will not be elaborated on further here.

[0033] In addition, it should be noted that the battery 207 is connected to the circuit board 204 via wires to supply power to the smoke sensor body 205 and the alarm 206. The battery 207 is existing technology and will not be elaborated on here.

[0034] The working principle of the smoke detection component 2 is as follows: the smoke sensor body 205 monitors the smoke concentration in the surrounding air in real time. When the smoke exceeds the standard, the smoke sensor body 205 transmits an electrical signal to the circuit board 204. After processing the signal, the circuit board 204 triggers the alarm 206 to issue an alarm and remind personnel to pay attention. During the detection process, the battery 207 can provide a stable power supply to ensure that the equipment can still operate normally in the event of a power outage. The filter shell 208 can block external dust and improve the detection accuracy.

[0035] In one embodiment, the push-pull disassembly mechanism 3 includes a connecting frame 301 disposed on the inner wall of one end of the mounting frame 1. A movable block 302 cooperating with the connecting frame 301 is disposed inside the connecting frame 301. A movable column 303 penetrating the connecting frame 301 is disposed on one side of the movable block 302, and a spring 304 connected to the connecting frame 301 is disposed on the other side of the movable block 302. A sliding groove 305 is formed at the top of the movable block 302, and a sliding column 306 cooperating with the sliding groove 305 is disposed inside the sliding groove 305. A connecting rod 307 connected to the connecting frame 301 is sleeved on the outer side of the top of the sliding column 306. A connecting block 307 connected to the movable column 303 and cooperating with the connecting frame 301 is disposed at the top of the sliding column 306. 08. The two ends of the connecting block 308 are provided with clamping blocks 309 connected to it, and the locking block 209 is located between the two sets of clamping blocks 309; the bottom of the other end of the mounting bracket 1 is provided with a stabilizing and reinforcing component 310 that cooperates with the push-pull handle 203; the cross-section of the locking block 209 is a trapezoidal structure, and the shape formed by the two sets of clamping blocks 309 is matched with the shape of the locking block 209; the cross-section of the slide groove 305 is a hexagonal heart structure; under the connection of the connecting rod 307 and the action of the sliding column 306 moving in the slide groove 305, the locking block 209 is firmly clamped by the two sets of clamping blocks 309, ensuring that the smoke detection component 2 can be quickly fixed in the mounting bracket 1, and can be easily released when disassembly is required, improving the overall operating efficiency and ease of use.

[0036] In addition, it should be noted that the clamping block 309 is made of elastic material, which allows it to undergo elastic deformation under the compression of the connecting frame 301.

[0037] In addition, it should be noted that when the fixing block 3103 is inserted into the push-pull handle 203, there is still a certain distance between the push-pull groove 101 and the push-pull plate 201 to ensure the subsequent movement of the push-pull plate 201.

[0038] The working principle of the push-pull disassembly mechanism 3 is as follows: When the locking block 209 moves with the push-pull plate 201 to contact the connecting block 308, the locking block 209 can squeeze the connecting block 308, causing the moving column 303 to move towards the spring 304. At the same time, it drives the moving block 302 to move towards the spring 304, causing the spring 304 to be compressed. Simultaneously, under the connection of the connecting rod 307 and the action of the sliding column 306 moving in the sliding groove 305, the sliding column 306 can move along the path of the sliding groove 305, causing the connecting rod 307 to move in an arc. The movement allows the sliding column 306 to move from one end of the slide groove 305 near the spring 304 to the other end. Simultaneously, the two sets of clamping blocks 309 move towards the spring 304 and into the connecting frame 301. Under the pressure of the connecting frame 301, the two sets of clamping blocks 309 move towards the locking block 209 and clamp it. When the sliding column 306 moves to the middle of the slide groove 305 away from the spring 304, one side of the connecting rod 307 is parallel to one end of the moving block 302, stopping the push-pull plate 201. The spring 304 then springs back... Under the action of the sliding rod 306, the sliding column 306 is locked in the middle of the end of the slide groove 305 away from the spring 304, and at the same time, the two sets of clamping blocks 309 lock the locking block 209. When disassembly is required, the push-pull plate 201 is pushed, causing the push-pull plate 201 to move the locking block 209 towards the spring 304, causing the moving column 303 and the moving block 302 to move towards the spring 304, causing the spring 304 to be compressed. Under the action of the connecting rod 307 and the sliding column 306 moving in cooperation within the slide groove 305, the sliding column 306 can move along the slide groove 305. The path movement of 5 causes the connecting rod 307 to make a reverse arc movement, and then stops pushing the push-pull plate 201. Under the elastic recovery action of the spring 304, the sliding column 306 can move from the middle of the other end of the slide groove 305 to the end of the slide groove 305 closer to the spring 304. At the same time, the two sets of clamping blocks 309 can move away from the spring 304 and move out of the connecting frame 301. Under the elastic recovery action, the two sets of clamping blocks 309 move away from the locking block 209 and no longer clamp the locking block 209, thereby realizing the disassembly of the smoke detection component 2.

[0039] In one embodiment, the aforementioned stabilizing and reinforcing component 310 includes a hollow limiting frame 3101 disposed at the bottom of the other end of the mounting bracket 1. Symmetrically arranged inside the hollow limiting frame 3101 are springs 3102 connected to the mounting bracket 1. Fixing blocks 3103 are disposed at the bottom of the two sets of springs 3102 and inside the push-pull handle 203. A movable handle 3104, penetrating the hollow limiting frame 3101, is disposed on the top of the fixing block 3103 and on the side away from the connecting bracket 301. The movement of the movable handle 3104 and the elastic force of the springs 3102 allow the fixing block 3103 to engage with the push-pull handle 203, further ensuring the stable installation of the smoke detection component 2 and enhancing the overall structural stability. Even under vibration or slight impact, it maintains a good fixed state, effectively preventing the risk of accidental triggering or equipment detachment.

[0040] The working principle of the stabilizing and reinforcing component 310 is as follows: When it is necessary to push or pull the push-pull plate 201, the operator needs to move the moving handle 3104 upwards by holding the handle 3104, which will cause the fixing block 3103 to move upwards, thus compressing the spring 3102. At the same time, the fixing block 3103 moves out of the push-pull handle 203. The operator can then push or pull the push-pull plate 201 by holding the handle 203 to achieve disassembly and installation. After the clamping operation of the locking block 209 is completed, the pushing of the push-pull plate 201 is stopped, and the sliding column... 306 moves to the middle of the end of the slide groove 305 away from the spring 304, and the fixing block 3103 moves to the top of the push-pull handle 203, and the fixing block 3103 is aligned with the push-pull handle 203. The moving handle 3104 is released, and under the elastic recovery action of the spring 3102, the moving handle 3104 moves downward, driving the fixing block 3103 to move downward into the inside of the push-pull handle 203, so that the fixing block 3103 and the push-pull handle 203 are engaged, further ensuring the stable installation of the smoke detection component 2.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] In practical applications, the mounting bracket 1 is installed on the wall through the cooperation of the bolts and threaded holes 102. By holding the moving handle 3104 and moving it upward, the fixing block 3103 is moved upward, causing the spring 3102 to compress. This prevents the fixing block 3103 from obstructing the movement of the push-pull plate 201. Then, by holding the push-pull handle 203, the push-pull plate 201 is aligned with the push-pull groove 101 and moved towards the spring 304. When the locking block 209 moves with the push-pull plate 201 to contact the connecting block 308, the locking block 209 can squeeze... The pressing connecting block 308 causes the movable column 303 to move closer to the spring 304, simultaneously driving the movable block 302 to move closer to the spring 304, compressing the spring 304. Simultaneously, with the connection of the connecting rod 307 and the coordinated movement of the sliding column 306 within the slide groove 305, the sliding column 306 moves along the path of the slide groove 305, causing the connecting rod 307 to perform an arc-shaped motion. This allows the sliding column 306 to move from one end of the slide groove 305 closer to the spring 304 to the other end. At the same time, the two sets of clamping blocks 309 move closer to the spring 304 and then to the connecting... Inside the connecting frame 301, and under the squeezing action of the connecting frame 301, the two sets of clamping blocks 309 move closer to the locking block 209 and clamp the locking block 209. When the sliding column 306 moves to the middle of the end of the slide groove 305 away from the spring 304, one side of the connecting rod 307 is parallel to one end of the moving block 302, stopping the push-pull plate 201. Under the elastic action of the spring 304, the sliding column 306 is locked in the middle of the end of the slide groove 305 away from the spring 304. At the same time, the two sets of clamping blocks 309 lock the locking block 209. The clamping operation of the locking block 209 is completed, and the push-pull plate 201 is stopped. At this time, the sliding column 306... 06 Move to the middle of the end of the slide groove 305 away from the spring 304, and move the fixing block 3103 above the push-pull handle 203, and align the fixing block 3103 with the push-pull handle 203. Release the moving handle 3104, and under the elastic recovery action of the spring 3102, the moving handle 3104 moves downward, driving the fixing block 3103 downward to the inside of the push-pull handle 203, so that the fixing block 3103 and the push-pull handle 203 are engaged, further ensuring the stable installation of the smoke detection component 2, and completing the installation of the push-pull smoke sensor. The push-pull smoke sensor can realize smoke detection and alarm.When the smoke detection component 2 needs to be disassembled for maintenance or replacement, the moving handle 3104 is moved upward again, causing the fixing block 3103 to move upward, compressing the second spring 3102. At the same time, the fixing block 3103 moves out of the push-pull handle 203. The operator can then disassemble the component by pushing and pulling the push-pull plate 201 with the push-pull handle 203. That is, by pushing the push-pull plate 201, the push-pull plate 201 causes the locking block 209 to move closer to the first spring 304, causing the moving column 303 and the moving block 302 to move closer to the first spring 304, compressing the first spring 304. Under the connection of the connecting rod 307 and the action of the sliding column 306 moving in cooperation within the slide groove 305, the sliding column 306 can move along the slide groove 305. The path movement causes the connecting rod 307 to make a reverse arc motion, and then stops pushing the push-pull plate 201. Under the elastic recovery action of the spring 304, the sliding column 306 can move from the middle of the other end of the slide groove 305 to the end of the slide groove 305 closer to the spring 304. At the same time, the two sets of clamping blocks 309 can move away from the spring 304 and move out of the connecting frame 301. Under the elastic recovery action, the two sets of clamping blocks 309 move away from the locking block 209 and no longer clamp the locking block 209. The connecting block 308 pushes the locking block 209 to move closer to the push-pull handle 203, so that the operator can pull the push-pull plate 201 out of the push-pull groove 101 through the push-pull handle 203, thereby realizing the disassembly of the smoke detection component 2.

[0043] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the mounting bracket 1, the smoke detection component 2, and the push-pull disassembly mechanism 3, not only can smoke detection and alarm be achieved, but also the smoke detection component 2 can be quickly installed and disassembled, improving maintenance efficiency, extending service life, and preventing loosening of connections. This ensures the overall stability and reliability of the installation, and improves the safety and robustness of the push-pull smoke sensor during long-term use. Through the push-pull disassembly mechanism 3, under the action of the connecting rod 307 and the sliding column 306 moving within the sliding groove 305, the push-pull disassembly mechanism allows for... The locking block 209 is firmly clamped by two sets of clamping blocks 309, ensuring that the smoke detection component 2 can be quickly fixed in the mounting bracket 1, and can be easily released when disassembly is required, improving the overall operating efficiency and ease of use; through the stabilizing reinforcement component 310, under the action of the movement handle 3104 and the elastic force of the spring 3102, the fixing block 3103 and the push-pull handle 203 are engaged, further ensuring the stable installation of the smoke detection component 2, enhancing the stability of the overall structure, and maintaining a good fixed state even under vibration or slight impact, effectively preventing the risk of accidental triggering or equipment falling off.
