Description

Technical Field

[0001] The utility model relates to the technical field of nail fixing device accessories, in particular to a pressure regulating silencer with a slag discharge function. Background Art

[0002] Many industrial equipment and tools, such as pneumatic or gunpowder-driven fastening devices, are often equipped with pressure-regulating silencers to achieve pressure regulation and noise control functions. Traditional pressure-regulating silencers are mainly composed of silencer pipes, pressure-regulating sleeves mounted on silencer pipes, and outer silencer jackets.

[0003] For a long time, this type of pressure-regulating silencer has had a significant limitation in design, namely, there are defects in the way it handles the residue generated internally during the working process. During the operation of the equipment, residue will be generated in situations such as gunpowder explosions or high-speed gas impacts. The slag discharge channel of the traditional pressure-regulating silencer usually allows the residue to first pass through the slag discharge silencer hole on the silencer pipe, and then enter the main body of the ceiling nail fixer through the slag discharge hole on the pressure regulating sleeve, and then be discharged from the protective cover of the ceiling nail fixer. For example, a ceiling nail fixer and a protective cover disclosed in Application No. 2023110069638; and a new type of automatic slag discharge mini ceiling nail fixer disclosed in Application No. 2021214123515. Another example is a pressure-regulating silencer disclosed in Application No. 2022231536833.

[0004] It can be seen that the pressure regulating silencer of the above structure does not have the ability to discharge slag itself, and the slag needs to pass through the nail fixing device body and then be discharged from the slag discharge channel of the nail fixing device body.

[0005] Since the residue must first enter the interior of the nail holder, despite continuous efforts to optimize the internal slag removal structure, it is still impossible to avoid the residue remaining and flowing inside the nail holder. The residue will cause serious damage to key components in the nail holder, such as the firing pin assembly. The corrosive components in the residue will gradually corrode the firing pin assembly, causing corrosion pits on its surface and reduced material strength. At the same time, the accumulation of residue can easily cause the firing pin assembly to be blocked and stuck, eventually causing the ceiling nail holder to be unable to operate normally, greatly reducing its working reliability and service life, increasing maintenance costs and usage risks, and bringing many inconveniences to the efficient development of building decoration work.

[0006] In summary, the existing pressure regulating silencer does not have the slag discharge capability and needs to discharge slag through the ceiling nail fixing device body. A series of problems caused by this urgently need to be effectively solved to improve the performance and stability of the entire ceiling nail fixing device system. Utility Model Content

[0007] In view of the deficiencies in the background technology, the utility model provides a pressure regulating silencer with a slag discharge function.

[0010] Furthermore, the outer ring of the pressure regulating sleeve is provided with at least one step ring, the muffler chamber is divided into a plurality of independent chambers by the step ring, and a slag discharge channel is provided on the step ring.

[0011] Furthermore, a step 1 is provided on the outer wall of the silencer pipe, and the step 1 abuts against the front end of the voltage regulating sleeve.

[0012] Furthermore, the rear end of the silencer sleeve has an internal thread threadedly connected to the return sleeve of the nail fixing device body, and the front end of the return sleeve is pressed tightly on the step 2 on the pressure regulating sleeve.

[0013] Furthermore, a sealing step is provided on the outer wall of the rear end of the noise-reducing sleeve, the sealing step is sealed and matched with the heat-insulating sleeve, and the noise-reducing sleeve and the heat-insulating sleeve are rotationally matched.

[0014] Furthermore, the slag discharge gap is divided into a plurality of slag discharge guide grooves by separation steps on the inner wall of the thermal insulation sleeve, and a slag discharge notch is provided at the front end of the thermal insulation sleeve.

[0018] The beneficial effects of the utility model are:

[0019] 1. Independent and efficient slag discharge to protect equipment components

[0020] The utility model provides a slag discharge hole on the silencer jacket, so that an independent discharge path for residues is formed between the slag discharge silencer hole on the silencer pipe, the silencer chamber between the silencer pipe and the silencer jacket, and the slag discharge hole on the silencer jacket, and the residues no longer need to enter the interior of the nail holder. This effectively prevents residues from entering the interior of the nail holder and causing damage to key components (such as the firing pin assembly) such as corrosion and jamming, greatly prolonging the service life of related equipment components, reducing the number and cost of repairs caused by component damage, improving the overall reliability and stability of the equipment, and ensuring the continuity and efficiency of building decoration or other related operations.

[0021] 2. Optimize the soundproofing performance and reduce noise pollution

[0022] The reasonable design of the silencing chamber and the slag discharge silencing hole can not only realize the slag discharge function, but also cooperate with the step ring on the pressure regulating sleeve to effectively reduce the noise generated during the operation of the equipment. Compared with the traditional pressure regulating silencer, the structure of the utility model optimizes the noise propagation path and the distribution of the silencing medium, so that the noise is more fully absorbed and reflected in the silencing chamber, thereby significantly reducing the noise level transmitted to the surrounding environment when the equipment is working. This creates a relatively quiet and comfortable working environment for operators, reduces the potential harm of noise to human health, and also meets environmental protection requirements and reduces noise pollution in the workplace.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] The utility model provides a pressure regulating silencer with a slag discharge function.

[0036] In this embodiment, refer to Figure 1-8 The pressure regulating silencer with slag discharge function comprises a silencer pipe 1, a pressure regulating sleeve 2 sleeved on the silencer pipe 1 and a silencer jacket 3 sleeved outside the pressure regulating sleeve 2, a silencer chamber 4 is formed between the silencer pipe and the silencer jacket, a slag discharge silencer hole 5 connected to the silencer chamber 4 is provided on the silencer pipe, and a slag discharge hole 6 is provided on the silencer jacket.

[0037] In the above technical solution, by setting a slag discharge hole on the silencer jacket, an independent discharge path for residues is formed between the slag discharge silencer hole on the silencer pipe, the silencer chamber between the silencer pipe and the silencer jacket, and the slag discharge hole on the silencer jacket, and the residues no longer need to enter the interior of the nail holder. This effectively prevents the residues from entering the interior of the nail holder and causing damage to key components (such as the firing pin assembly) such as corrosion and jamming, greatly prolonging the service life of related equipment components, reducing the number and cost of repairs caused by component damage, and eliminating the need to disassemble the main body of the nail holder to clean the residues inside the nail holder, thereby improving the overall reliability and stability of the equipment and ensuring the continuity and efficiency of building decoration or other related operations.

[0038] Specifically, it also includes a heat insulation sleeve 7 sleeved outside the silencer outer shell, a slag discharge gap 8 is left between the heat insulation sleeve 7 and the silencer outer shell, and the slag discharge gap 8 is connected to the silencer chamber through a slag discharge hole 6.

[0039] In this embodiment, by adding the heat insulation sleeve, not only a heat barrier is formed outside the silencer outer jacket, which effectively prevents the heat inside the silencer from diffusing outward, but also avoids the adverse effects of high temperature on external connection parts and the surrounding environment, such as preventing scalding of operators and reducing the damage to the performance of precision parts of adjacent equipment caused by heat. Moreover, the slag discharge gap between the heat insulation sleeve and the silencer outer jacket further improves the slag discharge channel. Through the shielding of the heat insulation sleeve, the residue can be prevented from being directly ejected from the slag discharge hole under high pressure, but firstly passes through the buffer of the slag discharge gap and then ejected from the front end of the silencer, which will not cause danger to the operator behind, thus improving its safety of use.

[0040] Specifically, the outer ring of the voltage regulating sleeve is provided with at least one step ring 9 , the muffler chamber is divided into a plurality of independent chambers 10 by the step ring 9 , and a slag discharge channel 11 is provided on the step ring 9 .

[0041] In this embodiment, the step ring of the outer ring of the pressure regulating sleeve divides the muffler chamber into multiple independent chambers, and a slag discharge channel is provided on the step ring. This structure can gradually optimize the muffler effect in different chambers, enhance the ability to reduce explosion noise, improve the muffler effect, and more effectively control the noise generated by the ceiling nail fixer during operation, reduce noise pollution in the working environment, and create relatively quiet and comfortable working conditions for operators. Among them, the slag discharge channel is used for muffler exhaust and also for the passage of residues.

[0042] Specifically, a step 12 is provided on the outer wall of the silencer pipe, and the step 12 abuts against the front end of the voltage regulating sleeve.

[0043] In the present embodiment, a step on the outer wall of the silencer pipe abuts against the front end of the pressure regulating sleeve. After the silencer outer sleeve and the return sleeve are threaded together, the pressure regulating sleeve can be stably pressed on the silencer pipe by the return sleeve. This structural design makes the installation of the silencer pipe inside the silencer more stable. After the silencer outer sleeve and the return sleeve are connected, the relative position relationship between the silencer pipe and the pressure regulating sleeve and the silencer outer sleeve is guaranteed to be stable, thereby maintaining the stability and reliability of the entire silencer structure. Moreover, the boltless structural design is easy to disassemble and assemble, and is convenient for cleaning the residue inside the silencer.

[0044] Specifically, the rear end of the silencer sleeve has an internal thread 14 threadedly connected to the return sleeve 13 of the nail fixing device body, and the front end of the return sleeve is pressed tightly on the step 2 15 on the pressure regulating sleeve.

[0045] In this embodiment, the silencer jacket is screwed to the return sleeve of the nail fixing body, which is convenient for disassembly and assembly. After the silencer jacket is screwed to the return sleeve, the step 4 23 on the silencer pipe and the step 5 24 on the silencer jacket interact with each other, and the silencer pipe, the pressure regulating sleeve and the silencer jacket are connected to the return sleeve of the nail fixing body as a whole for use. The entire silencer adopts a bolt-free structure, which is easy to disassemble and assemble, and it is convenient to clean the residue.

[0046] Specifically, a sealing step 16 is provided on the outer wall of the rear end of the noise-reducing jacket 3 , and the sealing step 16 is sealedly matched with the heat-insulating jacket 7 , and the noise-reducing jacket 3 is rotationally matched with the heat-insulating jacket 7 .

[0047] In this embodiment, the sealing step on the outer wall at the rear end of the silencer jacket seals the rear end of the slag discharge gap, constructing a reliable protective barrier, effectively preventing the residue from being ejected from the rear end of the slag discharge gap toward the user, greatly reducing the risk of injury to the user caused by the splashing of residue, significantly improving the safety of the ceiling nailer during use, and providing a safer working environment for operators. At the same time, the rotational fit between the silencer jacket and the insulation jacket provides a unique functional advantage. When residue is stuck in the slag discharge gap, the user can grind the stuck residue by rotating the silencer jacket and using the friction and extrusion force generated by the relative movement between the silencer jacket and the insulation jacket, so that the residue can be discharged smoothly, effectively avoiding the slag discharge failure caused by the residue blocking the slag discharge gap, ensuring the continuous and smooth operation of the slag discharge system, and further improving the reliability and practicality of the ceiling nailer.

[0048] Specifically, the slag discharge gap 8 is divided into a plurality of slag discharge guide grooves 18 by a dividing step 17 on the inner wall of the thermal insulation sleeve 7, and a slag discharge notch 19 is provided at the front end of the thermal insulation sleeve.

[0049] In this embodiment, the slag discharge gap is divided into a number of slag discharge guide grooves by the separation steps on the inner wall of the insulation sleeve, which can divert and guide the residue, so that the distribution of the residue in the slag discharge gap is more uniform and orderly, avoiding the problem of residue accumulation in a certain place and causing poor slag discharge; the slag discharge notch at the front end of the insulation sleeve provides an outlet for the residue to be discharged, further improving the efficiency and thoroughness of the slag discharge, and ensuring the efficient and stable operation of the slag discharge system.

[0050] Specifically, it also includes a dust cover 20 threadedly connected to the silencer pipe, and the silencer outer sleeve is provided with a step 3 21 that abuts against the separation step.

[0051] In this embodiment, the dust cover threadedly connected to the silencer pipe can effectively block dust, impurities, etc. from entering the silencer chamber and the slag discharge system, reducing the slag discharge failure or reduced silencing effect caused by the entry of foreign matter from the outside, and maintaining the cleanliness and normal function of the slag discharge system and the silencing structure; step three on the silencer outer sleeve offsets the separation step and is used to fix the position of the insulation sleeve, thereby enhancing the stability of the insulation sleeve during the slag discharge process, preventing it from being displaced due to vibration or other external forces, and ensuring the normal operation of the slag discharge guide trough.

[0052] Specifically, a plurality of grooves 22 are arranged at intervals on the outer wall of the heat insulation sleeve.

[0053] In this embodiment, the plurality of grooves arranged at intervals on the outer wall of the heat insulation sleeve have multiple functions. On the one hand, these grooves can increase the surface area of ​​the heat insulation sleeve, improve its heat dissipation efficiency, and to a certain extent help reduce the overall temperature of the muffler and further enhance the heat insulation effect; on the other hand, they increase the surface friction of the heat insulation sleeve, making it easier for users to hold and operate.

[0054] Specifically, the aperture of the slag discharge silencer hole is 1-2 mm, the height of the slag discharge gap is 1.5-2.5 mm, and the aperture of the slag discharge channel is 2-3 mm.

[0055] In this embodiment, when the nail fixer is working, the particle size of the exploded residue is generally less than 2mm, and is mostly in strip shape. Under high-pressure impact, it will be impacted through the inclined slag discharge silencer holes and be cut into smaller particles. After entering the slag discharge gap, these fine particles will expand due to heat or adhere to each other and become larger than 2mm. The height of the slag discharge gap is set to 1.5-2.5mm, and more specifically can be set to 2mm. The extrusion between the residue and the inner wall of the slag discharge gap can be used to slow down the direct ejection of the residue and improve safety in use.

[0056] In addition, the aperture of the slag discharge channel is set to 2-3 mm, more specifically 2.8 mm, which can ensure the smooth passage of the residue and at the same time ensure a good sound-absorbing effect.

[0057] The specific size ranges of the above-mentioned silencer slag discharge hole diameter, slag discharge gap height, and slag discharge channel diameter are optimized parameters obtained through a large number of experiments and practical verification. These dimensions can ensure effective slag discharge and silencing while achieving the best coordination between the various components, further improving the overall performance of the ceiling nailer, reducing problems such as poor slag discharge, poor silencing effect, or component wear that may arise due to unreasonable dimensions, improving the reliability and stability of the product, and providing clear and feasible technical indicators for industrial production.

[0058] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
