Description

Technical Field

[0001] This utility model relates to the field of household gas technology, specifically to a household gas alarm device that is easy to install. Background Technology

[0002] In household life, gas (such as natural gas and liquefied petroleum gas) is an important energy source widely used for cooking, heating, and many other purposes. With the acceleration of urbanization and the improvement of living standards, the usage rate of gas continues to rise. However, while gas brings convenience, it also harbors significant safety risks. Due to the flammability, explosiveness, and potential for poisoning (such as carbon monoxide poisoning in cases involving carbon-containing gases) of gas, leaks that are not detected and dealt with promptly can easily lead to serious accidents such as fires and explosions, causing devastating damage to the lives and health of family members and the safety of family property. As people's safety awareness increases, the demand for home gas alarm devices is becoming increasingly urgent.

[0003] In existing technologies, most gas alarm devices involve direct contact and compression between the housing and the outer surface of the pipeline during installation, which can easily lead to scratches and dents in the gas pipeline, potentially damaging the pipeline's seal and increasing the risk of gas leakage. Therefore, we provide a household gas alarm device that is easy to install. Utility Model Content

[0004] The purpose of this invention is to provide a household gas alarm device that is easy to install, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A household gas alarm device that is easy to install includes an alarm body, an upper cover at the bottom of the alarm body, and a lower cover detachably connected to the bottom of the upper cover.

[0007] Both ends of the upper and lower covers are provided with buffer cavities, and buffer protection blocks are movably installed inside the buffer cavities.

[0008] A further improvement of this utility model is that: a limiting groove is provided on both sides of the inner side of the buffer cavity, and a limiting slider is fixedly installed at the rear ends of both sides of the buffer protection block. The limiting slider is slidably connected inside the limiting groove, and the limiting groove can ensure that the movement of the buffer protection block is limited.

[0009] A further improvement of this utility model is that: a rubber protrusion is fixedly installed on the outer surface of the front end of the buffer protection block, a return spring is fixedly installed at the rear end of the buffer protection block, and the other end of the return spring is fixedly installed at the inner end of the buffer cavity. The rubber protrusion can enhance the locking friction and also serve a protective purpose.

[0010] A further improvement of this utility model is that: the top two sides of the lower cover are provided with insertion slots, and the bottom two sides of the upper cover are fixedly installed with insertion blocks, which are connected to the corresponding insertion slots.

[0011] A further improvement of this utility model is that: T-shaped locking grooves are provided on the outer surfaces of both sides of the lower cover, and locking holes are provided at the inner end of the T-shaped locking grooves.

[0012] A further improvement of this utility model is that: T-shaped locking plates are rotatably connected to the outer surfaces of both sides of the upper cover, and the T-shaped locking plates have through holes inside.

[0013] A further improvement of this utility model is that: the interior of the T-shaped locking plate is connected to a matching locking bolt at the through hole, and the other end of the locking bolt is connected to a matching locking hole.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a household gas alarm device that is easy to install. By providing a plug-in block at the bottom of the upper cover and a corresponding plug-in slot at the top of the lower cover, the upper and lower covers can be initially positioned by simply inserting the plug-in block into the appropriate plug-in slot during installation, thus avoiding misalignment during the splicing process. After the initial splicing, the T-shaped locking plates on both sides of the upper cover are rotated to embed into the corresponding T-shaped locking slots of the lower cover. The limiting characteristics of the T-shaped structure restrict the relative displacement of the upper and lower covers. Then, the locking bolts are passed through the through holes of the T-shaped locking plates and screwed into the locking holes in the T-shaped locking slots to form a double fixation, ensuring that the device tightly wraps the gas pipeline, thereby promoting the ease of installation.

[0016] 2. This utility model provides a household gas alarm device that is easy to install. It has buffer cavities on the inner walls of both the upper and lower covers. A rubber protrusion is installed at the front end of the buffer protection block in the buffer cavity, and a return spring is connected to the rear end. When installed, the pipe squeezes the rubber protrusion. The rubber protrusion initially buffers the impact force through its own elasticity. At the same time, the buffer protection block moves into the buffer cavity, compressing the return spring. The spring generates a reverse elastic force to further offset the squeezing force, thus preventing the pipe from being scratched, deformed or damaged due to excessive force, thereby protecting the pipe.

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a household gas alarm device that is easy to install, including an alarm body 1, an upper cover 2 at the bottom of the alarm body 1, and a lower cover 3 detachably connected to the bottom of the upper cover 2. Buffer cavities 31 are provided on the inner walls of both ends of the upper cover 2 and the lower cover 3. Buffer protection blocks 32 are movably installed inside the buffer cavities 31. Limiting grooves 33 are provided on both sides of the inside of the buffer cavities 31. Limiting sliders 34 are fixedly installed at the rear ends of both sides of the buffer protection blocks 32. The limiting sliders 34 are slidably connected inside the limiting grooves 33. Rubber protrusions 35 are fixedly installed on the outer surface of the front end of the buffer protection blocks 32. A return spring 36 is fixedly installed at the rear end of the buffer protection blocks 32. The other end of the return spring 36 is fixedly installed inside the buffer cavity 31.

[0026] Furthermore, after installation, the outer surface of the pipe will contact the rubber protrusion 35 at the front end of the buffer protection block 32. As the upper cover 2 and the lower cover 3 gradually close, the pipe exerts a squeezing force on the rubber protrusion 35. The rubber protrusion 35 deforms due to its own elastic properties, initially buffering the direct collision between the pipe and the protection block. At the same time, the buffer protection block 32 moves into the buffer cavity 31 under the squeezing action. At this time, the return spring 36 at the rear end of the buffer protection block 32 is compressed, and the spring generates a reverse elastic force, further offsetting the squeezing force on the pipe and preventing damage to the pipe due to excessive force. During this process, the limiting sliders 34 on both sides of the buffer protection block 32 will slide synchronously along the limiting grooves 33 on the inner wall of the buffer cavity 31, ensuring that the buffer protection block 32 always moves along a fixed trajectory, preventing it from shifting or tilting during the buffering process, ensuring the stability and uniformity of the buffering effect, and effectively reducing the wear on the outer surface of the gas pipe during the installation of the device.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the top two sides of the lower cover 3 are provided with insertion slots 37, and the bottom two sides of the upper cover 2 are fixedly installed with insertion blocks 21. The insertion blocks 21 are connected to the corresponding insertion slots 37. The outer surfaces of the two sides of the lower cover 3 are provided with T-shaped locking slots 38. The inner end of the T-shaped locking slots 38 is provided with locking holes 39. The outer surfaces of the two sides of the upper cover 2 are rotatably connected with T-shaped locking plates 22. The interior of the T-shaped locking plates 22 is provided with through holes 23. The interior of the T-shaped locking plates 22 is connected to the through holes 23 with a corresponding locking bolt 24. The other end of the locking bolt 24 is connected to the corresponding locking hole 39.

[0029] Furthermore, the upper cover 2 and lower cover 3 are separated and attached to both sides of the gas pipeline, so that the gas pipeline is placed within the cavity formed by the upper cover 2 and lower cover 3. During the operation, the insertion blocks 21 on both sides of the bottom of the upper cover 2 and the insertion slots 37 on both sides of the top of the lower cover 3 must be aligned. The insertion blocks 21 are then smoothly inserted into the insertion slots 37 to complete the initial splicing and positioning of the upper cover 2 and lower cover 3. At this point, the two can initially cover the outer surface of the gas pipeline to prevent misalignment during installation. After the initial splicing, the T-shaped locking plates 22 on the outer surfaces of the two sides of the upper cover 2 are rotated to lock the gas pipeline in place. The locking plate 22 is rotated into the corresponding T-shaped locking grooves 38 on both sides of the lower cover 3. Since the shapes of the T-shaped locking plate 22 and the T-shaped locking grooves 38 are compatible, the relative displacement of the upper cover 2 and the lower cover 3 can be further restricted to ensure that the two fit tightly. Then, the locking bolt 24 is passed through the through hole 23 inside the T-shaped locking plate 22 and aligned with the locking hole 39 at the inner end of the T-shaped locking groove 38. The locking bolt 24 is rotated clockwise until the bolt is fully screwed into the locking hole 39 and cannot be rotated any further. At this time, the upper cover 2 and the lower cover 3 are firmly locked, and the installation of the gas pipeline is completed.

[0030] The working principle of this easy-to-install household gas alarm device will be explained in detail below.

[0031] like Figure 1-5As shown, during use, first separate the upper cover 2 and the lower cover 3, and attach them to both sides of the gas pipeline so that the gas pipeline is within the cavity formed by the upper cover 2 and the lower cover 3. During operation, align the insertion blocks 21 on both sides of the bottom of the upper cover 2 with the insertion slots 37 on both sides of the top of the lower cover 3, and smoothly insert the insertion blocks 21 into the insertion slots 37 to complete the initial splicing and positioning of the upper cover 2 and the lower cover 3. At this point, the two can initially cover the outer surface of the gas pipeline to avoid misalignment during installation. After the initial splicing, rotate... The T-shaped locking plates 22 on the outer surfaces of the upper cover 2 rotate into the corresponding T-shaped locking grooves 38 on both sides of the lower cover 3. Since the shapes of the T-shaped locking plates 22 and the T-shaped locking grooves 38 are compatible, the relative displacement between the upper cover 2 and the lower cover 3 can be further restricted, ensuring that the two fit tightly. Then, the locking bolts 24 are passed through the through holes 23 inside the T-shaped locking plates 22 and aligned with the locking holes 39 at the inner end of the T-shaped locking grooves 38. The locking bolts 24 are rotated clockwise until the bolts are fully screwed into the locking mechanism. When the hole 39 is closed and cannot be rotated further, the upper cover 2 and the lower cover 3 are firmly locked, completing the installation of the gas pipeline. After installation, the outer surface of the pipeline will contact the rubber protrusion 35 at the front end of the buffer protection block 32. As the upper cover 2 and the lower cover 3 gradually close, the pipeline exerts a squeezing force on the rubber protrusion 35. The rubber protrusion 35 deforms due to its own elastic properties, initially buffering the direct collision between the pipeline and the protection block. At the same time, the buffer protection block 32 moves into the buffer cavity 31 under the squeezing action. At this time, the return spring 36 at the rear end of the buffer protection block 32 is compressed, and the spring generates a reverse elastic force, further offsetting the squeezing force on the pipeline and preventing damage to the pipeline due to excessive force. During this process, the limiting sliders 34 on both sides of the buffer protection block 32 will slide synchronously along the limiting grooves 33 on the inner wall of the buffer cavity 31, ensuring that the buffer protection block 32 always moves along a fixed trajectory, preventing it from shifting or tilting during the buffering process, ensuring the stability and uniformity of the buffering effect, and effectively reducing the wear on the outer surface of the gas pipeline during the installation of the device.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
