Description

Technical Field

[0001] This utility model relates to the field of fire detector technology, specifically a point-type heat-sensing fire detector. Background Technology

[0002] In automatic fire alarm systems, point-type heat detectors are key equipment, playing a crucial role in real-time monitoring of ambient temperature changes and timely detection of fire hazards. Currently, most point-type heat detectors on the market typically adopt a split-assembly design. Specifically, the sensing module, as the core component, is mounted on the base and requires precise positioning and fixation using specialized locking components to ensure the stability and reliability of the sensing module during operation. After the sensing module is installed, the protective cover must be connected to the base, and a corresponding locking structure must be used again to achieve a secure connection between the two, thereby protecting the sensing module and preventing external environmental factors from interfering with its normal operation.

[0003] However, this traditional assembly method has obvious drawbacks. Due to the multiple steps involved, such as the installation of the sensing module, double locking, and connection of the protective cover, the overall assembly process is quite cumbersome. This not only increases the manual operation cost and time cost in the production process and reduces production efficiency, but also makes it easy to introduce human operation errors in the assembly process of multiple components, affecting the assembly accuracy and consistency of the product, thereby reducing the overall reliability and stability of the product. Therefore, it is necessary to design a point-type heat-sensing fire detector to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a point-type heat-sensing fire detector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a point-type heat-sensing fire detector, including a base, wherein the inner cavity of the base is provided with a limiting component for limiting connection and initial locking with the sensing module; the inner cavity of the base is also provided with a locking component for locking the protective cover to the outside of the base, thereby completing the stable locking of the sensing module.

[0006] Preferably, the inner cavity of the base is provided with a limiting seat, the sensing module and the limiting seat are connected by a plug-in limiting connection, and both the sensing module and the limiting seat are provided with notches, so that the limiting component can complete the initial locking.

[0007] Preferably, the limiting component includes a limiting ring and multiple sets of limiting blocks installed on the inner wall of the limiting ring. The limiting blocks slide in cooperation with the notch, and the limiting component can be initially locked to the limiting seat by rotating the limiting ring.

[0008] Preferably, the protective cover and the base are connected by a plug-in connection. The locking component includes multiple sets of connecting seats circumferentially distributed in the inner cavity of the base, springs built into the inner cavities of each set of connecting seats, and a locking tongue connected to one end of the springs. When the protective cover is inserted into the base, the locking tongue pops out and inserts into the protective cover under the action of the springs, thereby locking the protective cover and the base.

[0009] Preferably, multiple sets of first baffles are equidistantly installed on the circumference of the protective cover away from the base, and the other end of each of the first baffles is connected to a second baffle.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Compared with the multiple steps of traditional split assembly, this utility model reduces the operation steps, eliminates the need for double locking, and directly completes the installation and fixation of the sensing module and protective cover through the limiting component and locking component, which greatly shortens the assembly time, simplifies the assembly process, reduces manual operation steps, lowers manual operation costs, improves the assembly accuracy and consistency of the product, and thus improves the overall reliability and stability of the product.

[0012] 2. This utility model does not require an additional complex locking structure, reduces the number of parts, lowers production costs and assembly complexity. It only requires inserting and removing the limiting ring and simple rotation operation. Compared with the traditional locking method, there are fewer steps and higher assembly efficiency. This design has relatively low requirements for installation accuracy. Even if there is a certain installation error, the initial limiting can be achieved through the cooperation of the limiting block with the notch and slide, which is convenient for mass production.

[0013] 3. The first baffle and the second baffle, which are equidistantly installed on the circumference of the protective cover away from the base, are connected to form a semi-enclosed protective structure for further protection. The operation process of inserting and unplugging first and then rotating and locking is clear, conforms to human operating habits, is easy for workers to master, reduces assembly difficulty, and has a compact structure design that occupies little space, which is conducive to the miniaturization design of the detector.

[0020] 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.

[0021] Example 1

[0022] Please refer to Figure 1-5 As shown, this utility model provides a point-type heat-sensing fire detector, including a base 1. The inner cavity of the base 1 is provided with a limiting component for limiting connection and initial locking with the sensing module 2. The inner cavity of the base 1 is also provided with a locking component for locking the protective cover 10 to the outside of the base 1, thereby completing the stable locking of the sensing module 2.

[0023] When installing the sensing module 2, it is placed inside the cavity of the base 1. The limiting component functions to make a limiting connection with the sensing module 2, achieving initial locking and determining the position of the sensing module 2. When installing the protective cover 10, it is placed over the outside of the base 1. The locking component inside the cavity of the base 1 is activated, firmly locking the protective cover 10 onto the base 1. As the protective cover 10 is locked, it applies a certain pressure to the sensing module 2. Together with the limiting component, it completes the stable locking of the sensing module 2, ensuring its stability during operation.

[0024] Compared to the multiple steps of traditional modular assembly, this solution reduces the number of steps and eliminates the need for double locking. The sensor module 2 and the protective cover 10 are directly installed and fixed through the limiting and locking components, which greatly shortens the assembly time, simplifies the assembly process, reduces manual operation steps, lowers manual operation costs, improves the assembly accuracy and consistency of the product, and thus enhances the overall reliability and stability of the product.

[0025] Specifically, the inner cavity of the base 1 is provided with a limiting seat 3. The sensing module 2 and the limiting seat 3 are connected by a plug-in limiting connection. Both the sensing module 2 and the limiting seat 3 are provided with notches 4. With the help of the limiting component, the initial locking can be completed. The limiting component includes a limiting ring 5 and multiple sets of limiting blocks 6 installed on the inner wall of the limiting ring 5. The limiting blocks 6 are slidably engaged with the notches 4. The initial locking between the limiting component and the limiting seat 3 can be achieved by rotating the limiting ring 5.

[0026] When installing the sensing module 2, first insert it into the limiting seat 3 to achieve initial plug-in positioning. At the same time, align the sensing module 2 with the notch 4 on the limiting seat 3, put the limiting ring 5 on the limiting seat 3, and insert the limiting block 6 on the inner wall of the limiting ring 5 into the notch 4 until it is fully inserted. At this time, the limiting ring 5 can rotate along the slide opened in the limiting seat 3. Due to the cooperation between the slide of the limiting seat 3 and the limiting ring 5, as well as the limiting effect of the limiting block 6 and the notch 4, the movement of the sensing module 2 can be restricted within a certain range, thereby achieving initial positioning.

[0027] No additional complex locking structure is required, reducing the number of parts, production costs and assembly complexity. It only requires plugging and unplugging the limit ring 5 and simple rotation operation. Compared with traditional locking methods, there are fewer steps and higher assembly efficiency. This design has relatively low requirements for installation accuracy. Even if there is a certain installation error, the limit block 6 can achieve initial limiting through the cooperation of notch 4 and slide, which is convenient for mass production.

[0028] Wherein: the protective cover 10 and the base 1 are connected by a plug-in type. The locking component includes multiple sets of connecting seats 7 circumferentially distributed in the inner cavity of the base 1, springs 8 built into the inner cavity of each set of connecting seats 7, and a locking tongue 9 connected to one end of the springs 8. When the protective cover 10 is inserted into the base 1, the locking tongue 9 pops out and inserts into the protective cover 10 under the action of the springs 8, thereby locking the protective cover 10 and the base 1. Multiple sets of first baffles 11 are circumferentially installed on the side of the protective cover 10 away from the base 1, and the other end of each first baffle 11 is connected to a second baffle 12.

[0029] First, the protective cover 10 and the base 1 are connected by a plug-in method to initially combine them. At this time, the locking tongue 9 overcomes the elastic force of the spring 8 under the compression of the protective cover 10 and retracts into the inner cavity of the connecting seat 7. After the plug-in connection is completed, the protective cover 10 is rotated. When the protective cover 10 is rotated to a specific position, the corresponding hole of the protective cover 10 is aligned with the locking tongue 9. The locking tongue 9 pops out under the action of the spring 8 and inserts into the corresponding hole of the protective cover 10, thereby locking the protective cover 10 and the base 1. The first baffle 11 and the second baffle 12, which are equidistantly installed on the circumference of the protective cover 10 away from the base 1, are connected to form a semi-enclosed protective structure for further protection. The plug-in and then rotation locking method has a clear operation process, conforms to human operating habits, is easy for workers to master, reduces assembly difficulty, and has a compact structural design that occupies little space, which is conducive to the miniaturization design of the detector.

[0030] Working principle: When installing the sensing module 2, first insert it into the limiting seat 3 to achieve initial plug-in positioning. Simultaneously, align the sensing module 2 with the notch 4 on the limiting seat 3. Place the limiting ring 5 over the limiting seat 3, and align the limiting block 6 on the inner wall of the limiting ring 5 with the notch 4 before inserting it until fully inserted. At this point, the limiting ring 5 can rotate along the slide rail on the limiting seat 3. Due to the cooperation between the slide rail of the limiting seat 3 and the limiting ring 5, as well as the limiting effect of the limiting block 6 and the notch 4, the movement of the sensing module 2 within a certain range is restricted. The protective cover 10 is moved to achieve initial positioning. Then, the protective cover 10 and the base 1 are connected by a plug-in method to make the two initially combined. At this time, the locking tongue 9 overcomes the elastic force of the spring 8 under the pressure of the protective cover 10 and retracts into the inner cavity of the connecting seat 7. After the plug-in connection is completed, the protective cover 10 is rotated. When the protective cover 10 is rotated to a specific position, the corresponding hole of the protective cover 10 is aligned with the locking tongue 9. The locking tongue 9 pops out under the action of the spring 8 and inserts into the corresponding hole of the protective cover 10 to achieve locking between the protective cover 10 and the base 1.
