Description

Technical Field

[0001] This utility model relates to the field of alarm testing technology, and more specifically, to a soundproof bag for testing sound and light alarms. Background Technology

[0002] Currently, in fire alarm system testing, audible and visual alarms must meet the stringent sound pressure level requirements of GB 26851-2011 standard, and must undergo durability testing according to EN54-3, operating continuously for 100 hours. Furthermore, during load testing, multiple audible and visual alarms must be activated simultaneously, resulting in noise peaks significantly exceeding 70dB during testing, causing serious noise pollution to testing personnel and the surrounding environment.

[0003] Currently, during the testing of the A9091T audible and visual alarm, the alarm is wall-mounted. Mainstream noise reduction methods, such as noise-canceling headphones, duct tape sealing, or sound-absorbing foam shielding, all have a single core flaw: they cannot simultaneously achieve efficient operation and reduce noise in the surrounding environment. For example, noise-canceling headphones only protect the individual and affect operational agility; duct tape sealing is time-consuming, costly, and difficult to reuse; sound-absorbing foam has poor adaptability and cannot provide real-time observation of the light signal. Therefore, a testing solution is needed that combines efficient operation with environmental noise reduction. Utility Model Content

[0004] The technical problem this invention aims to solve is the inability to simultaneously reduce noise in the surrounding environment while operating efficiently. To address the aforementioned deficiencies in the prior art, this invention provides a soundproof bag for testing sound and light alarm devices.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A soundproof bag for testing an audible and visual alarm includes a soundproof bag body with a placement position inside the bag body for placing the alarm during testing; a soundproof component is arranged inside the bag body around the placement position, the soundproof component is interference-fitted with the sound-emitting hole of the alarm, and the soundproof component is detachably connected inside the bag body.

[0007] The soundproof bag has a drawstring at the opening for sealing and wrapping the alarm.

[0008] By adopting the above technical solution, during the testing process, the alarm is wall-mounted on the wall, and the soundproof bag 1 can directly wrap around the alarm and clip the soundproofing component into the sound hole of the alarm. The soundproofing component and the soundproof bag provide a double-layer soundproofing effect. The soundproof bag is tied at the top, making the operation convenient and quick. It not only reduces noise during testing but can also be reused. The soundproofing component and the sound hole are perfectly matched to directly cover the sound source and prevent sound leakage, resulting in a more significant targeted noise reduction effect.

[0009] Preferably, the sound insulation component is detachably connected to the inside of the sound insulation bag body. The inside of the sound insulation bag body is provided with a fixing buckle. The fixing buckle has a T-shaped cross-section. The sound insulation component is provided with a connection hole that matches the fixing buckle. The side wall of the sound insulation component near the connection hole is provided with an installation port. The installation port communicates with the connection hole. The installation port is provided with a fastener for fixing the installation port.

[0010] By adopting the above technical solution, the sound insulation component is installed on the fixing buckle before testing. The installation port, T-shaped fixing buckle and connection hole can be matched with fasteners to simplify the assembly and avoid complicated operation. The fasteners ensure that the sound insulation component fits the sound-emitting hole and prevent displacement during the test, which may cause sound leakage.

[0011] Preferably, the sound insulation component includes an upper layer of sound insulation cotton and a lower layer of sound insulation cotton. The upper layer of sound insulation cotton is in the form of thin strips and is fixed around the circumference of the placement position. The lower layer of sound insulation cotton is in the form of blocks and is slidably connected to the bottom of the sound insulation bag.

[0012] By adopting the above technical solution, the upper and lower sound insulation cotton can be compatible with different models of alarms according to different usage conditions. The design of the upper sound insulation cotton surrounding the inner circumference can eliminate edge sound leakage and enhance the overall sound insulation effect.

[0013] Preferably, a sliding rail is provided circumferentially on the inner wall of the soundproof bag near the lower soundproof cotton, the fixing buckle is slidably connected to the sliding rail, the end of the fixing buckle is provided with a T-shaped recess, and a snap-fit ​​part is provided on the sliding rail corresponding to the T-shaped recess.

[0014] By adopting the above technical solution, the fixed buckle can slide on the sliding rail to effectively change the position of the lower sound insulation cotton, so as to adapt to different models of alarms for testing.

[0015] Preferably, soundproofing strips are wrapped around both the drawstring and the inside of the opening of the soundproof bag.

[0016] By adopting the above technical solution, the drawstring can be tightened with a single pull, improving operational efficiency. At the same time, the soundproof strips at the openings of the drawstring and the soundproof bag not only eliminate sound leakage points and improve noise reduction capabilities, but also protect the drawstring from wear and extend its service life.

[0017] Preferably, the soundproof bag body is provided with an observation part, the observation part is semi-transparent, and a soundproof strip is provided at the connection between the observation part and the soundproof bag body.

[0018] By adopting the above technical solution, the working status of the alarm and light signals of the alarm can be observed through the observation section, avoiding noise leakage caused by frequent opening and closing of the soundproof bag. At the same time, the soundproof strip at the connection can further reduce sound wave leakage.

[0019] Preferably, the soundproof bag is wrapped with a soundproof layer, which is evenly covered at the lower end of the soundproof bag.

[0020] By adopting the above technical solutions, the sound insulation layer can effectively block the noise transmitted by the vibration of the sound insulation bag itself, and covering the bottom of the sound insulation bag can effectively block external reflected sound, enabling it to adapt to more complex environmental tests, and also avoiding the impact of excessively thickening the bag on the convenience of operation.

[0021] Preferably, the soundproof bag can be fully unfolded into a flat surface from the side, and both ends of the soundproof bag are provided with drawstrings. The side of the soundproof bag is provided with a fixing part and a connecting part. The fixing part can cover the connecting part. An adhesive strip is provided on the inner side of the fixing part, and an attachment strip is provided on the outer side of the connecting part and adhered to the adhesive strip.

[0022] By adopting the above technical solution, the soundproof bag can be fully unfolded, which not only makes it easier to insert the soundproofing component into the alarm sound hole during the test, but also facilitates the replacement of the soundproofing component and the cleaning of the inside of the soundproof bag. Through the cooperation between the fixing part and the connecting part, the packaging process can be further simplified and the operation efficiency can be improved.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. By installing soundproofing components, during testing, the alarm is wall-mounted on the wall, and the soundproofing bag 1 can directly wrap around the alarm. The soundproofing components are then snapped into the sound hole of the alarm, and the soundproofing bag is tied at the top. The soundproofing components and the soundproofing bag provide a double-layer soundproofing effect. The operation is convenient and quick. It not only reduces noise during testing but can also be reused. The soundproofing components are newly installed and matched with the sound hole, which can directly cover the sound source and prevent sound leakage. The targeted noise reduction effect is more significant.

[0025] 2. By setting an upper layer of sound insulation cotton and a lower layer of sound insulation cotton, and allowing the lower layer of sound insulation cotton to slide inside the sound insulation bag, the upper and lower layers of sound insulation cotton can be compatible with different models of alarms according to different usage conditions. The design of the upper layer of sound insulation cotton surrounding the inner circumference can eliminate edge sound leakage and enhance the overall sound insulation effect; the fixed buckle sliding on the sliding rail can effectively change the position of the sound insulation component to adapt to different alarms for testing.

[0026] 3. By setting a drawstring, it is possible to tighten the drawstring with one pull, which improves the efficiency of operation. At the same time, the drawstring and the opening of the soundproof bag are equipped with soundproof strips, which not only eliminate sound leakage points and improve noise reduction, but also protect the drawstring from wear and extend its service life.

[0027] 4. By setting up an observation section, the working status of the alarm and light signals of the alarm can be observed, avoiding noise leakage caused by frequent opening and closing of the soundproof bag. At the same time, the soundproof strip at the connection can further reduce sound wave leakage. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example 1

[0036] A soundproof bag for testing audible and visual alarms, reference Figure 1-3 It includes a soundproof bag body 1, a soundproof component 2, and a drawstring 3.

[0037] The soundproof bag body 1 is wrapped with a soundproof layer 11, which is evenly covered at the lower end of the soundproof bag body 1. The soundproof bag body 1 is elastic, and a drawstring 3 is provided at the opening of the soundproof bag body 1. An observation part 12 is provided on the soundproof bag body 1. The observation part 12 is semi-transparent, and a soundproof strip 13 is provided at the connection between the observation part 12 and the soundproof bag body 1.

[0038] The sound insulation layer 11 can effectively block the noise transmitted by the vibration of the sound insulation bag 1 itself. Covering the lower end of the sound insulation bag 1 can effectively block external reflected sound, enabling it to adapt to more complex environmental tests, and also avoiding the impact of excessively thickening the sound insulation bag 1 on the convenience of operation.

[0039] The observation section 12 allows observation of the alarm and light signal status of the alarm device, avoiding frequent opening and closing of the soundproof bag 1 which could lead to noise leakage. At the same time, the soundproof strip 13 at the connection point can further reduce sound wave leakage.

[0040] The soundproof bag 1 has a placement position 16 inside, which is used to place the alarm during testing. The soundproof component 2 is arranged around the placement position 16. The soundproof component 2 is interference-fitted with the sound-emitting hole of the alarm and is detachably connected to the inside of the soundproof bag 1. The soundproof bag 1 has a fixing buckle 14 inside, which has a T-shaped cross-section. The soundproof component 2 has a connecting hole 21 that matches the fixing buckle 14. The side wall of the soundproof component 2 near the connecting hole 21 has an installation port 22 that communicates with the connecting hole 21. The installation port 22 has a fastener 23 for fixing the installation port 22.

[0041] During the testing process, the alarm was wall-mounted on the wall. The soundproof bag 1 could directly wrap around the alarm, and the soundproofing component 2 was snapped into the sound hole of the alarm. The soundproof bag 1 was then tied at the top, making the operation convenient and quick. It not only reduced noise during testing but was also reusable. The soundproofing component 2 matched the shape of the sound hole, which could directly cover the sound source and prevent sound leakage, resulting in a more significant targeted noise reduction effect.

[0042] Before testing, the sound insulation component 2 is installed on the fixing buckle 14 and the mounting port can be fixed by the fastener 23. The T-shaped fixing buckle 14 and the connecting hole 21 simplify the assembly and avoid complicated operations. The fastener 23 ensures that the sound insulation component 2 fits the sound-emitting hole and prevents displacement during the test, which may cause sound leakage.

[0043] The sound insulation component 2 includes an upper layer of sound insulation cotton 24 in the form of thin strips and a lower layer of sound insulation cotton 25 in the form of blocks. The upper layer of sound insulation cotton 24 is evenly distributed around the inner circumference of the sound insulation bag 1, and the lower layer of sound insulation cotton 25 is slidably installed inside the sound insulation bag 1. A sliding rail 15 is provided circumferentially on the inner wall of the sound insulation bag 1 near the lower layer of sound insulation cotton 25. A fixing buckle 14 is slidably connected to the sliding rail 15. The end of the fixing buckle 14 has a T-shaped recess 141, and a snap-fit ​​part 151 is provided on the sliding rail 15 corresponding to the T-shaped recess 141.

[0044] The upper sound insulation cotton 24 and the lower sound insulation cotton 25 are compatible with different models of alarms depending on the application. The upper sound insulation cotton 25's surrounding design eliminates edge sound leakage and enhances the overall sound insulation effect. The fixing buckle 14 slides on the sliding rail 15, which can effectively change the position of the sound insulation component 2 to adapt to different alarms for testing.

[0045] A drawstring 3 is threaded through the opening of the soundproof bag 1, and soundproof strips 13 are wrapped around both the drawstring 3 and the inside of the opening of the soundproof bag 1.

[0046] The drawstring 3 allows for easy tightening with a single pull, improving operational efficiency. Additionally, the opening between the drawstring 3 and the soundproof bag 1 includes a soundproof strip 13, which not only eliminates sound leakage points and enhances noise reduction capabilities but also protects the drawstring 3 from wear and extends its service life.

[0047] The implementation principle of the soundproof bag for testing an audible and visual alarm in this application embodiment is as follows: During the audible and visual alarm test, the alarm is wall-mounted on the wall, and the soundproof bag 1 can directly wrap and cover the alarm. It slides on the sliding rail 15 by fixing buckle, thereby adjusting the lower layer of soundproof cotton 25 to a suitable position and placing the lower layer of soundproof cotton 15 into the sound hole of the alarm. The soundproof bag 1 is tightened by the drawstring 3. During the test, the alarm status of the alarm can be observed through the observation part 12.

[0048] Example 2

[0049] Except for the unfolding structure of the soundproof bag 1, the structure of this embodiment is the same as that in Example 1, and will not be described in detail here. (Reference) Figure 4 The soundproof bag 1 can be fully unfolded into a flat surface from the side. Both ends of the soundproof bag 1 are provided with drawstrings 3. The side of the soundproof bag 1 is provided with a fixing part 4 and a connecting part 5. The fixing part 4 can cover the connecting part 5. The inner side of the fixing part 4 is provided with an adhesive strip 41, and the outer side of the connecting part 5 is provided with an attachment strip 51 that is adhered to the adhesive strip 41.

[0050] This allows the soundproof bag 1 to be fully unfolded, which not only makes it easier to insert the soundproofing component 2 into the alarm sound hole during testing, but also makes it easier to replace the soundproofing component 2 and clean the inside of the soundproof bag 1. The cooperation between the fixing part 4 and the connecting part 5 can further simplify the packaging process and improve operational efficiency.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
