Description

Technical Field

[0001] This utility model relates to the technical field of ceiling nail fasteners, specifically a ceiling nail fastener, a noise-reducing voltage regulator, and a noise-reducing housing. Background Technology

[0002] In the construction industry, ceiling fasteners are commonly used tools, and the performance of their silencers and pressure regulators is crucial. These silencers and pressure regulators not only need to have slag removal capabilities to ensure the normal operation of the equipment, but also need to balance noise reduction and pressure regulation to create a better construction environment and ensure stable equipment operation. Specific structures include a ceiling fastener disclosed in application number 2025100465562, and a pressure-regulating silencer with slag removal capabilities disclosed in application number 2025200661120.

[0003] The existing silencing shell structure of the ceiling-mounted nail silencing regulator only includes a heat insulation sleeve, with a second slag discharge hole 32 on the outer silencing sleeve. During the slag discharge process, ash and slag directly enter the slag discharge gap between the heat insulation sleeve and the outer silencing sleeve through the second slag discharge hole of the outer silencing sleeve, and then exit the equipment. Practical experience has shown that this slag discharge method has certain drawbacks. On the one hand, the shorter slag discharge path reduces the silencing effect; on the other hand, the existing structure places the dividing step inside the heat insulation sleeve, and machining the step inside the sleeve significantly increases the processing difficulty, not only consuming a lot of labor time but also resulting in high processing costs, seriously affecting the product's market competitiveness.

[0004] In view of the shortcomings of the existing technology, there is an urgent need to develop a new type of silencing shell structure that can extend the slag discharge path, enhance the silencing effect, reduce costs, and improve operational safety. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a sound-absorbing shell and a ceiling fastener.

[0006] The technical solution adopted by this utility model is: a sound-absorbing shell, which is applied to the sound-absorbing pressure regulator of the ceiling fastener. The sound-absorbing shell includes a sound-absorbing partition and a heat insulation sleeve fitted outside the sound-absorbing partition. A slag discharge gap is left between the heat insulation sleeve and the sound-absorbing partition. A first slag discharge hole is provided on the sound-absorbing partition. A front sealing step, a rear sealing step, and multiple dividing steps are provided on the sound-absorbing partition.

[0007] The front sealing step and the rear sealing step are set at both ends of the sound-absorbing sleeve. The dividing step extends from the front sealing step to the rear sealing step, and a connecting channel is left between the end of the dividing step and the rear sealing step. The dividing step divides the slag discharge gap formed by the front sealing step and the rear sealing step into a first slag discharge channel and a second slag discharge channel. The first slag discharge channel and the second slag discharge channel are connected by a connecting channel.

[0008] The outer circumference of the front sealing step is provided with slag discharge outlets that communicate with the second slag discharge channel.

[0009] There are multiple first slag discharge holes, which are spaced apart and arranged around the perimeter of the first slag discharge channel on the side near the front sealing step.

[0010] Furthermore, the outer ring of the rear sealing step is provided with a positioning step, the positioning step is provided with a positioning protrusion, and the heat insulation sleeve is provided with a notch that matches the positioning protrusion.

[0011] Furthermore, the outer wall of the front sealing step is provided with positioning grooves at intervals, and the inner wall of the heat insulation sleeve is provided with positioning bosses that are nested and cooperate with the positioning grooves at intervals.

[0012] Furthermore, the front end of the heat insulation sleeve is provided with a surrounding step that covers the front end of the sound-absorbing sleeve, and the surrounding step is provided with slag discharge slots corresponding to the slag discharge outlet at intervals.

[0013] Furthermore, both the first and second slag discharge channels are provided with interval steps extending from the rear sealing step to the front sealing step, and the top of the interval step is spaced a distance 'a' from the front sealing step.

[0014] Furthermore, blocking protrusions are provided on both sides of the dividing step.

[0015] Furthermore, the dividing steps can be a straight line structure, a wavy structure, or a combination of a straight line structure and a wavy structure.

[0016] This application also provides a silencer and pressure regulator, which is applied to a ceiling fastener. The silencer includes a silencer pipe, a pressure regulating sleeve fitted on the silencer pipe, a silencer outer sleeve fitted outside the pressure regulating sleeve, and the aforementioned silencer housing fitted outside the silencer outer sleeve. A first silencer chamber is formed between the silencer pipe and the silencer outer sleeve, and a second silencer chamber is formed between the silencer outer sleeve and the silencer partition. The silencer pipe has a slag discharge and silencer hole communicating with the first silencer chamber. The first slag discharge hole connects the second silencer chamber and the slag discharge gap. The first silencer chamber and the second silencer chamber are connected through a second slag discharge hole on the silencer outer sleeve.

[0017] Furthermore, the outer ring of the pressure regulating sleeve is provided with at least one stepped ring, and the first silencing chamber is divided into multiple independent compartments by the stepped ring, and the stepped ring is provided with a slag discharge through hole.

[0018] This application also provides a ceiling nail fastener, wherein the head of the ceiling nail fastener is equipped with the aforementioned silencer and voltage regulator, and the silencer sleeve of the silencer and voltage regulator is threadedly connected to the return sleeve of the ceiling nail fastener.

[0019] The beneficial effects of this utility model are:

[0020] 1. Improved Noise Reduction: By adding a noise-reducing sleeve and incorporating a front sealing step, a rear sealing step, and multiple dividing steps on the sleeve, a new slag discharge path is formed. Ash discharged from the first slag discharge hole must flow sequentially through the first slag discharge channel, the connecting channel, and the second slag discharge channel before finally exiting from the slag discharge outlet. This tortuous path effectively extends the slag discharge distance. With the significantly extended discharge path, the ash comes into more frequent contact and friction with the internal structure of the noise-reducing sleeve during its flow, allowing for more effective noise absorption and dissipation, thus significantly enhancing the noise reduction effect.

[0021] 2. Reduce costs and enhance product competitiveness: Unlike existing technologies that place the partition steps inside the heat insulation sleeve, this application places the partition steps on the sound-absorbing sleeve. Directly machining the steps on the outer wall of the sleeve is less technically difficult and operationally challenging than machining them on the inner wall of the hole, significantly reducing machining time and thus substantially lowering production costs, effectively enhancing the product's competitiveness in the market.

[0022] 3. Improved Safety: The extended slag discharge path provides additional safety. As the ash flows through the long discharge channel, its speed gradually decreases, providing ample buffering. This effectively prevents residue from being ejected at high speed, greatly reducing the risk of accidental injury to operators and comprehensively improving operational safety.

[0023] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0034] This utility model provides a ceiling nail fastener, a noise-reducing voltage regulator, and a noise-reducing housing.

[0035] In this embodiment, refer to Figure 1-8 A sound-absorbing housing is used in the sound-absorbing pressure regulator of a ceiling fastener. The sound-absorbing housing includes a sound-absorbing sleeve 1 and a heat-insulating sleeve 2 fitted outside the sound-absorbing sleeve. A slag discharge gap 3 is left between the heat-insulating sleeve 2 and the sound-absorbing sleeve. A first slag discharge hole 4 is provided on the sound-absorbing sleeve. A front sealing step 5, a rear sealing step 6 and multiple dividing steps 7 are provided on the sound-absorbing sleeve 1.

[0036] The front sealing step and the rear sealing step are set at both ends of the sound-absorbing sleeve. The dividing step extends from the front sealing step to the rear sealing step, and a connecting channel 8 is left between the end of the dividing step and the rear sealing step. The dividing step divides the slag discharge gap formed by the front sealing step and the rear sealing step into a first slag discharge channel 9 and a second slag discharge channel 10. The first slag discharge channel 9 and the second slag discharge channel 10 are connected by the connecting channel 8.

[0037] The outer circumference of the front sealing step is provided with slag discharge outlets 11 that communicate with the second slag discharge channel 10;

[0038] There are multiple first slag discharge holes, which are spaced apart and arranged around the perimeter of the first slag discharge channel on the side near the front sealing step.

[0039] In the above technical solution, front and rear sealing steps are set at both ends of the sound-absorbing sleeve. Multiple dividing steps separate the slag discharge gap into first and second slag discharge channels, which are connected by a connecting channel. The first slag discharge hole is located on the side of the first slag discharge channel closest to the front sealing step, and slag discharge outlets connecting to the second slag discharge channel are distributed around the outer circumference of the front sealing step. This structural design requires the ash and slag to pass through different slag discharge channels sequentially after being discharged from the first slag discharge hole, forming a tortuous slag discharge path. This structure effectively extends the slag discharge path, enhances the sound absorption effect, and ensures that the ash and slag fully contact and rub against the internal structure of the sound-absorbing sleeve during flow, reducing noise. It also provides a long-distance buffer for residual slag, preventing high-speed spray from injuring people.

[0040] As shown in the attached figure, the front and rear sealing steps are ring-shaped and set at both ends of the soundproofing sleeve. There are multiple dividing steps, specifically 8 or 6. This application takes 8 steps as an example, which are evenly distributed on the outer peripheral wall of the soundproofing sleeve.

[0041] The first slag discharge hole and the slag discharge outlet are alternately arranged. The slag discharged from the first slag discharge hole needs to pass through the first and second slag discharge channels and the connecting channel before finally being discharged from the slag discharge outlet. The slag discharge path is as follows: Figure 7 and 8 As indicated by the arrow.

[0042] Specifically, the outer ring of the rear sealing step is provided with a positioning step 13, the positioning step 13 is provided with a positioning protrusion 14, and the heat insulation sleeve is provided with a notch 15 that matches the positioning protrusion 14.

[0043] In this embodiment, a positioning step is provided on the outer ring of the rear sealing step, and a positioning protrusion is provided on it. A notch is provided at the corresponding position of the heat insulation sleeve. The positioning step is used to determine the depth at which the heat insulation sleeve is fitted into the sound-absorbing sleeve. The matching relationship between the positioning protrusion and the notch ensures the correct fitting and positioning of the heat insulation sleeve and the sound-absorbing sleeve during installation. This facilitates the assembly of the heat insulation sleeve and the sound-absorbing sleeve, improves installation efficiency, ensures the accurate relative position of the two, and guarantees the overall structural stability and the normal functioning of slag removal, noise reduction, and other functions.

[0044] Specifically, the outer wall of the front sealing step is provided with positioning grooves 16 at intervals, and the inner wall of the heat insulation sleeve is provided with positioning bosses 17 that are nested and cooperate with the positioning grooves at intervals.

[0045] In this embodiment, a positioning groove is provided on the outer wall of the front sealing step, and a positioning boss is provided on the inner wall of the heat insulation sleeve to nest and cooperate with it. Through the cooperation of the groove and the boss, the precise positioning of the heat insulation sleeve and the front end of the sound-absorbing sleeve is achieved. Working in conjunction with the protrusions and notches mentioned above, this further improves the accuracy of the installation and positioning of the heat insulation sleeve and the sound-absorbing sleeve, enhances the assembly quality, and ensures the overall performance of the sound-absorbing shell. Moreover, the positioning boss on the inner wall of the heat insulation sleeve can also play a reinforcing role, improving the mechanical strength of the heat insulation sleeve during breakage.

[0046] Specifically, the front end of the heat insulation sleeve is provided with a surrounding step 18 that covers the front end of the sound-absorbing sleeve, and the surrounding step 18 is provided with slag discharge slots 19 corresponding to the slag discharge outlet at intervals.

[0047] In this embodiment, the front end of the heat insulation sleeve is provided with a surrounding step to cover the front end of the sound-absorbing insulation sleeve, and the surrounding step is provided with slag discharge slots corresponding to the slag discharge outlet at intervals. The slag discharge slots correspond to the slag discharge outlet and are used for ash and slag discharge.

[0048] Specifically, both the first slag discharge channel 9 and the second slag discharge channel 10 are provided with interval steps 20 extending from the rear sealing step to the front sealing step, and the top of the interval step 20 is separated from the front sealing step by a distance a21.

[0049] In this embodiment, interval steps extending from the rear sealing step to the front sealing step are provided in the first and second slag discharge channels. The top of the interval steps is spaced a distance α from the front sealing step. The interval steps further block and guide the flow of ash and slag in the slag discharge channels, which helps to enhance the buffering and noise reduction effect.

[0050] Specifically, the two sides of the dividing step are provided with blocking protrusions 23.

[0051] In this embodiment, as Figure 5 As shown, blocking protrusions 23 are set on both sides of the dividing steps. The blocking protrusions 23 can play a role in sound insulation and block sound, further improving the sound absorption effect.

[0052] Specifically, the dividing steps are straight, wavy, or a combination of straight and wavy structures.

[0053] In this embodiment, as Figure 3 , 4 As shown in Figure 7, the partition steps adopt a straight structure, a wavy structure, or a combination of both. The wavy structure or the combined structure can increase the contact area and friction frequency between the ash and the partition steps, play a role in sound insulation and noise reduction, further improve the noise reduction effect, and optimize the noise reduction performance of slag discharge.

[0054] This application also provides a silencer and pressure regulator, which is applied to a ceiling fastener. It includes a silencer tube 24, a pressure regulating sleeve 25 fitted on the silencer tube 24, a silencer outer sleeve 33 fitted outside the pressure regulating sleeve 25, and the aforementioned silencer outer shell fitted outside the silencer outer sleeve 33. A first silencer chamber 26 is formed between the silencer tube and the silencer outer sleeve, and a second silencer chamber 31 is formed between the silencer outer sleeve and the silencer partition. The silencer tube is provided with a slag discharge and silencer hole 37 that communicates with the first silencer chamber. The first slag discharge hole 4 connects the second silencer chamber 31 and the slag discharge gap. The first silencer chamber 26 and the second silencer chamber 31 are connected through a second slag discharge hole 32 on the silencer outer sleeve.

[0055] The silencer and pressure regulator in the above technical solution includes a silencer pipe, a pressure regulator sleeve, a silencer outer sleeve, and a silencer housing. A first silencer chamber is formed between the silencer pipe and the silencer outer sleeve, and a second silencer chamber is formed between the silencer outer sleeve and the silencer partition sleeve. At the same time, a slag discharge and silencer hole is provided on the silencer pipe, which is connected to the first silencer chamber. The first slag discharge hole is connected to the second silencer chamber. The silencer and slag discharge function of the silencer housing is combined with the silencer pipe and the pressure regulator sleeve to achieve organic integration of slag discharge, silencer and pressure regulation functions, thereby improving the slag discharge and silencer effect of the ceiling fastener silencer and pressure regulator.

[0056] After adopting this solution for the silencer and pressure regulator, the slag discharge path is as follows: Figure 8 As shown, the slag needs to be discharged from the slag discharge silencing hole → first silencing chamber → second slag discharge hole → second silencing chamber → first slag discharge hole → first slag discharge channel → connecting channel → second slag discharge channel → slag discharge outlet. This significantly increases the slag discharge and silencing path of the silencing regulator, thereby improving its silencing effect.

[0057] Specifically, the outer ring of the pressure regulating sleeve is provided with at least one stepped ring 28, and the first silencing chamber is divided into multiple independent compartments by the stepped ring 28. The stepped ring is provided with a slag discharge through hole 29.

[0058] Multiple stepped rings are set on the outer ring of the pressure regulating sleeve. The stepped rings divide the first silencing chamber into multiple independent compartments. The stepped rings are equipped with slag discharge holes to further optimize the silencing and slag discharge effect in the silencing chamber. The multiple independent compartments can block, buffer and treat noise and ash multiple times, thereby improving the silencing effect of the silencing pressure regulator.

[0059] This application also provides a ceiling nail fastener, the head of which is equipped with the aforementioned silencer and voltage regulator, and the silencer sleeve 33 of the silencer and voltage regulator is threadedly connected to the return sleeve 30 of the ceiling nail fastener.
