Description

Technical Field

[0001] The utility model relates to the technical field of nail fixing devices, in particular to a slag discharge silencer. Background Art

[0002] Among many industrial equipment and tools, such as pneumatic or gunpowder-driven fastening devices (e.g. ceiling nailers), pressure-regulating silencers are often equipped 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, such as a pressure-regulating silencer disclosed in application number 2022231536833. When in use, in order to increase the heat insulation effect, a heat insulation jacket is usually put on the outer surface of the silencer jacket.

[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 pressure-regulating 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, such as a ceiling nail fixer and protective cover disclosed in application number 2023110069638; and a new type of automatic slag discharge mini ceiling nail fixer disclosed in application number 2021214123515. The pressure-regulating silencers of the above structures do not have the ability to discharge slag themselves. The slag needs to pass through the main body of the nail fixer before being discharged from the slag discharge channel of the main body of the nail fixer.

[0004] Since the debris must first enter the interior of the nail holder, despite continuous efforts to optimize the internal debris removal structure, it is still impossible to prevent the residue from remaining and flowing inside the nail holder. The debris can cause serious damage to key components in the nail holder, such as the firing pin assembly.

[0005] In addition, in traditional designs, the insulation sleeve is usually made of plastic material, but when high-temperature residue is directly sprayed onto the insulation sleeve, it is easy to cause aging and corrosion of the material, thereby shortening the service life of the insulation sleeve and reducing the insulation effect.

[0006] In order to solve these problems, an improved slag discharge silencer design is needed, which can effectively handle and discharge the residue without affecting the performance of the equipment, protect the internal components from the influence of the residue, and effectively protect the insulation sleeve to increase the service life of the insulation sleeve.

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

[0008] The technical solution adopted by the utility model is: a slag discharge silencer, including a silencer pipe, a pressure regulating sleeve sleeved on the silencer pipe, a silencer outer sleeve sleeved outside the pressure regulating sleeve, and a heat insulation sleeve sleeved on the silencer outer sleeve, and also including a heat dissipation slag discharge sleeve sleeved between the heat insulation sleeve and the silencer outer sleeve, a slag discharge silencer gap 1 is provided between the heat dissipation slag discharge sleeve and the silencer outer sleeve, a slag discharge silencer gap 2 is provided between the heat insulation sleeve and the heat dissipation slag discharge sleeve, a silencer slag discharge port 1 is provided on the outer wall of the heat insulation sleeve, and a silencer slag discharge port 2 is provided on the outer wall of the heat dissipation slag discharge sleeve;

[0009] The slag discharge and silencer gap one is connected to the slag discharge and silencer gap two through the slag discharge and silencer port three on the heat dissipation and slag discharge sleeve, and the slag discharge and silencer gap one is connected to the stapling channel in the silencer pipe through the slag discharge channel.

[0010] Furthermore, the slag discharge channel includes a silencer chamber formed between the silencer pipe and the silencer sleeve, a pressure regulating silencer hole on the silencer pipe connected to the silencer chamber, and a slag discharge hole on the silencer sleeve for connecting the silencer chamber and the slag discharge silencer gap.

[0011] 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 the step ring is provided with a slag discharge through hole.

[0012] Furthermore, the silencer sleeve is provided with a step 1 and a step 2, and the above-mentioned slag discharge silencer gap 1 is formed between the step 1 and the step 2.

[0013] Furthermore, a dust cover is screwed on the front end of the silencer sleeve, and a clamping step is provided on one end of the heat insulation sleeve and the heat dissipation and slag removal sleeve, and the clamping step is clamped between the dust cover and step one.

[0014] Furthermore, a positioning ring groove is provided on one end of the heat insulation sleeve away from the clamping step, and a positioning convex ring engaged with the positioning ring groove is provided on one end of the heat dissipation and slag removal sleeve away from the clamping step.

[0015] Furthermore, the length X of the second slag discharge silencer gap is 1.5-3 times the length Y of the first slag discharge silencer gap.

[0016] Furthermore, the silencer slag discharge port 1 is located at a side away from the pressure regulating sleeve, and the heat dissipation slag discharge sleeve located at one side of the silencer slag discharge port 1 has a guide inclined surface that is tilted outward.

[0017] Furthermore, it also includes a main sleeve, and the silencer slag discharge port is located on the side where the main sleeve can extend into the extreme position of the heat dissipation and slag discharge sleeve.

[0018] Furthermore, a return sleeve is screwed onto the silencer outer sleeve, and a silencer chamber is formed between the return sleeve and the heat dissipation and slag removal sleeve.

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

[0020] 1. Protect the thermal insulation sleeve and extend its service life: a heat dissipation and slag discharge sleeve is arranged between the thermal insulation sleeve and the silencer outer sleeve. The residue coming out of the slag discharge channel first enters the slag discharge and silencer gap 1, is buffered and insulated by the slag discharge heat dissipation channel, and then enters the slag discharge and silencer gap 2, which reduces the impact and corrosion of the residue on the thermal insulation sleeve, reduces the direct corrosion to the thermal insulation sleeve, extends the service life of the thermal insulation sleeve, and maintains the stability of its thermal insulation performance.

[0021] 2. Improve the heat insulation and silencing effect: The design of the slag silencing gap 1 and the slag silencing gap 2 not only buffers and guides the discharge of the residue, but also further optimizes the silencing structure. During the flow of the residue in the two gaps, the sound energy is further consumed, which enhances the silencing effect. At the same time, the double-layer gap structure and the setting of the heat dissipation slag sleeve enhance the heat insulation performance, reduce the impact of the internal high temperature on the heat insulation sleeve, and better maintain the heat insulation effect.

[0022] 3. Optimize the slag discharge path: The traditional pressure regulating silencer needs to rely on the main body of the nail holder to discharge slag. Instead, the slag is discharged directly from the silencer slag discharge port 1 and the silencer slag discharge port 2 after passing through the slag discharge channel. This allows the residue to be effectively processed within the structure of the silencer itself, avoiding the residue from entering the nail holder. This fundamentally solves the problem of residue damage to key components of the nail holder, such as the firing pin assembly, extending the service life of the nail holder and ensuring the stable operation of the equipment.

[0023] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] 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.

[0032] The utility model provides a slag discharge silencer.

[0033] In this embodiment, refer to Figure 1-5 The slag discharge silencer comprises a silencer pipe 1, a pressure regulating sleeve 2 sleeved on the silencer pipe 1, a silencer outer jacket 3 sleeved outside the pressure regulating sleeve 2, and a heat insulation sleeve 4 sleeved on the silencer outer jacket 3, and also comprises a heat dissipation slag discharge sleeve 5 sleeved between the heat insulation sleeve 4 and the silencer outer jacket 3, a slag discharge silencer gap 1 6 is provided between the heat dissipation slag discharge sleeve 5 and the silencer outer jacket, a slag discharge silencer gap 2 7 is provided between the heat insulation sleeve and the heat dissipation slag discharge sleeve, a silencer slag discharge port 1 8 is provided on the outer wall of the heat insulation sleeve, and a silencer slag discharge port 2 9 is provided on the outer wall of the heat dissipation slag discharge sleeve;

[0034] The slag discharge and silencer gap 1 is connected to the slag discharge and silencer gap 2 through the slag discharge and silencer port 3 10 on the heat dissipation and slag discharge sleeve, and the slag discharge and silencer gap 1 6 is connected to the stapling channel 11 in the silencer pipe 1 through the slag discharge channel.

[0035] In the above technical solution, a heat dissipation and slag discharge sleeve is added between the thermal insulation sleeve and the silencer outer sleeve, and slag discharge silencer gap one, slag discharge silencer gap two and corresponding slag discharge channels are set, so as to provide a specific buffer and discharge path for the residue. When discharging slag, the residue in the stapling channel will pass through the stapling channel in turn through the slag discharge silencer gap one and the slag discharge silencer gap two, and finally be discharged from the slag discharge silencer port one and the slag discharge lower silencer port two. On the one hand, it avoids the residue from directly impacting the silencer outer sleeve and the thermal insulation sleeve, thereby extending the service life of both; on the other hand, it optimizes the silencer and heat insulation structure, and enhances the silencer and heat insulation effect. At the same time, this design changes the traditional way of slag discharge that relies on the main body of the nail holder. The independent slag discharge channel effectively prevents the residue from entering the interior of the nail holder and protects the key components of the nail holder.

[0036] Specifically, the slag discharge channel includes a silencer chamber 12 formed between the silencer pipe and the silencer sleeve, a pressure regulating silencer hole 13 on the silencer pipe connected to the silencer chamber 12, and a slag discharge hole 14 on the silencer sleeve for connecting the silencer chamber and the slag discharge silencer gap.

[0037] In this embodiment, the specific composition of the slag discharge channel is clarified. The muffler chamber formed between the muffler pipe and the muffler jacket, as a part of the muffler structure, also undertakes the slag discharge function. The arrangement of the pressure regulating muffler hole and the slag discharge hole enables the residue to enter the slag discharge muffler gap 1 from the nailing channel in the muffler pipe in an orderly manner, thus optimizing the slag discharge process. After adopting the above slag discharge channel, the residue no longer needs to pass through the inside of the nailer, thus ensuring a smooth slag discharge process and helping to improve the muffler effect.

[0038] Among them, the pressure regulating and silencing hole is a general term for the pressure regulating hole and the silencing hole. This structural setting is the existing technology and has the capabilities of silencing, pressure regulating and slag discharge.

[0039] Specific slag discharge path reference for the muffler Figure 3 The arrow in the .

[0040] Specifically, at least one step ring 15 is provided on the outer ring of the voltage regulating sleeve, and the muffler chamber is divided into a plurality of independent chambers by the step ring 15 . A slag discharge through hole 16 is provided on the step ring.

[0041] In this embodiment, the silencing chamber can be divided into multiple chambers by setting a step ring, and a slag discharge through hole is set on the step ring, and the sound and residue can pass through the silencing chamber through the slag discharge through hole. This structure can gradually optimize the silencing effect in different chambers, enhance the ability to reduce explosion noise, improve the silencing 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.

[0042] Specifically, the silencer sleeve is provided with a step 17 and a step 2 18, and the slag discharge silencer gap 1 is formed between the step 1 and the step 2.

[0043] In this embodiment, by setting step one and step two, a natural slag removal and noise reduction gap one is formed between the heat dissipation and slag removal sleeve.

[0044] Specifically, a dust cover 19 is screwed on the front end of the silencer jacket, and a clamping step 20 is provided on one end of the heat insulation jacket and the heat dissipation and slag removal jacket, and the clamping step 20 is clamped between the dust cover and step one.

[0045] In this embodiment, the dust cover screwed on the front end of the silencer sleeve cooperates with the compression steps on the thermal insulation sleeve and the heat dissipation and slag removal sleeve to achieve reliable fixation of one end of the thermal insulation sleeve and the heat dissipation and slag removal sleeve. The thermal insulation sleeve and the heat dissipation and slag removal sleeve can be aligned with the help of the dust cover without other fasteners, and disassembly and assembly are convenient.

[0046] Specifically, a positioning ring groove 21 is provided on one end of the heat insulation sleeve away from the pressing step, and a positioning convex ring 22 engaged with the positioning ring groove is provided on one end of the heat dissipation and slag removal sleeve away from the pressing step.

[0047] In this embodiment, the positioning ring groove on the heat insulation sleeve is engaged with the positioning protruding ring on the heat dissipation and slag removal sleeve, so as to fix the other end of the heat insulation sleeve and the heat dissipation and slag removal sleeve to each other.

[0048] Specifically, the length X of the second slag discharge silencer gap is 1.5-3 times the length Y of the first slag discharge silencer gap.

[0049] In this embodiment, the length of the slag discharge silencer gap 2 is set to 1.5-3 times the length of the slag discharge silencer gap 1, which is an optimized design based on the flow characteristics of the residue and the silencer requirements. The longer slag discharge silencer gap 2 provides a longer flow path for the residue, so that it has more time to dissipate heat and silence in the gap, further reducing the temperature of the residue and the noise during discharge, improving the overall slag discharge silencer effect, and avoiding the direct discharge of the residue with residual temperature.

[0050] Specifically, the silencer slag discharge port 1 is located at a side away from the pressure regulating sleeve, and the heat dissipation slag discharge sleeve located at one side of the silencer slag discharge port 1 has a guide inclined surface 23 that is tilted outward.

[0051] In this embodiment, the silencer slag discharge port 1 is located on the side away from the pressure regulating sleeve and the heat dissipation slag discharge sleeve is provided with an outward-curved guide slope. This design is conducive to guiding the residue to be discharged quickly and smoothly from the slag discharge silencer gap 2, avoiding the accumulation of residue near the silencer slag discharge port 1. At the same time, the guide slope can also play a certain scattering effect on the discharged residue, further reducing the noise generated during discharge.

[0052] The slope of the guiding slope 23 may be 10-30 degrees, more specifically 15 degrees.

[0053] Specifically, it also includes a main sleeve, and the silencer slag discharge port is located on the side where the main sleeve 25 can extend into the extreme position of the heat dissipation and slag discharge sleeve.

[0054] In this embodiment, the second slag discharge and silencer port is located on the side where the main sleeve can extend into the extreme position of the heat dissipation and slag discharge sleeve, ensuring that during the movement of the main sleeve, the extended main sleeve does not cover the second slag discharge and silencer port, so that the residue can enter the second slag discharge and silencer gap from the second slag discharge and silencer port in time, avoiding the accumulation of residue in the heat dissipation and slag discharge sleeve, ensuring the continuity and stability of the slag discharge process, and further ensuring the normal realization of the slag discharge and silencer function.

[0055] Specifically, a return sleeve 24 is screwed onto the silencer outer sleeve, and a silencer chamber is formed between the return sleeve and the heat dissipation and slag removal sleeve.

[0056] In this embodiment, when the main sleeve moves relative to the return sleeve, the main sleeve blocks the gap between the return sleeve and the heat dissipation and slag removal sleeve, so that a silencer chamber is naturally formed, which can further improve the silencer effect.

[0057] 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.
