Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a pressure regulating sleeve. Background Art

[0002] The utility model relates to the technical field of silencers, and specifically to a pressure regulating sleeve of a pressure regulating silencer. The pressure regulating sleeve is one of the main accessories of the pressure regulating silencer, and is mainly used in conjunction with the silencer pipe to achieve slag discharge silencer and pressure adjustment. For example, a pressure regulating silencer disclosed in application number 2022231536833, although the pressure regulating sleeve can achieve a stable pressure regulating function, its silencer effect still has room for improvement in some application scenarios.

[0003] In the existing pressure regulating silencer design, the pressure regulating sleeve is usually directly matched with the silencer pipe, and the pressure regulation and slag ash discharge are achieved by adjusting the relative position between the two. However, this design has limitations in the silencing effect, especially in applications that require high silencing performance, the pressure regulating sleeve directly matched with the silencer pipe cannot meet the strict silencing requirements, and there is still room for improvement.

[0004] In addition, the pressure regulating sleeve of the above structure is provided with a channel for chip removal on the annular step (equivalent to the clamping step part of the present application), and the residue coming out of the muffler is discharged into the nail holder from the channel. Since the residue must first enter the interior of the nail holder body, 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 can 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, decreased material strength and other problems. At the same time, the accumulation of residue can easily lead to obstruction of the movement of the firing pin assembly and jamming, which will eventually cause the ceiling nail holder to fail to operate normally, greatly reducing its working reliability and service life, increasing maintenance costs and use risks, and bringing many inconveniences to the efficient development of building decoration work. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a pressure regulating sleeve.

[0006] The technical solution adopted by the utility model is: a pressure regulating sleeve, comprising a casing section and a compression step on the end of the casing section, the casing section is provided with a pressure regulating hole, the casing section is provided with at least one step ring, and the step ring is provided with a slag discharge channel for chip discharge.

[0007] Furthermore, the slag discharge channel is a hole-type structure that penetrates the annular step.

[0008] Furthermore, the hole structure is a circular structure or an equilateral polygonal structure.

[0009] Furthermore, the diameter of the circular hole structure is 2-3 mm.

[0010] Furthermore, the slag discharge channel is a groove-shaped structure that penetrates the annular step.

[0011] Furthermore, the groove structure is a semicircular groove structure or a "U"-shaped groove structure or a notch structure.

[0012] Furthermore, there are two step rings, which are arranged at intervals on the casing section.

[0013] Furthermore, the pressure regulating hole is arranged between two step rings.

[0014] Furthermore, the clamping step and the step ring are arranged with the same diameter.

[0015] The beneficial effects of the utility model are:

[0016] 1. Improve the silencing effect: By providing at least one step ring on the casing section of the pressure regulating sleeve and providing a slag discharge channel for chip discharge on the step ring, the gap between the silencer jacket (equivalent to the gland) and the pressure regulating sleeve of the silencer can be divided into multiple chambers. This structural design can effectively reduce the direct propagation of sound inside the silencer, thereby significantly improving the silencing effect of the silencer.

[0017] 2. Enhanced structural stability: The step ring not only improves the silencing effect, but also enhances the structural stability of the voltage regulating sleeve. As an additional supporting structure, the step ring can improve the pressure resistance of the voltage regulating sleeve in a high-pressure environment and ensure the reliability of the voltage regulating sleeve in long-term use.

[0018] 3. Provide a new slag discharge channel: the channel on the clamping step is cancelled, and the connection between the pressure regulating sleeve and the return sleeve on the nail holder body is closed, so as to prevent the residue from directly entering the nail holder body, and effectively avoid the corrosion and jamming of the key components in the nail holder such as the firing pin assembly by the residue.

[0027] 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.

[0028] 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.

[0029] The utility model provides a pressure regulating sleeve.

[0030] In this embodiment, refer to Figure 1-6 The pressure regulating sleeve comprises a casing section 1 and a compression step 2 on the end of the casing section 1, the casing section 1 is provided with a pressure regulating hole 3, the casing section 1 is provided with at least one step ring 4, and the step ring 4 is provided with a slag discharge channel 5 for chip discharge.

[0031] In the above technical solution, by arranging at least one step ring on the casing section and providing a slag discharge channel for chip discharge on the step ring, the presence of the step ring enables the gap between the silencer outer sleeve and the pressure regulating sleeve of the silencer to be divided into multiple chambers, thereby greatly improving the silencer performance of the silencer.

[0032] In addition, the channel on the clamping step is eliminated, and the connection between the pressure regulating sleeve and the return sleeve on the nail fixing body is closed, so that the residue can be prevented from directly entering the nail fixing body, effectively avoiding the corrosion and jamming of the key components such as the firing pin assembly in the nail fixing body by the residue. Moreover, the slag discharge channel on the pressure regulating sleeve of the present application and the slag discharge hole on the muffler jacket can form a new slag discharge channel system, preventing the residue from directly entering the nail fixing body.

[0033] Specifically, the slag discharge channel is a hole-shaped structure that penetrates the annular step; the hole-shaped structure is a circular structure or an equilateral polygonal structure.

[0034] A hole structure that runs through the annular steps is used as the chip removal channel. Its regular shape is conducive to the smooth passage of slag and ash. Compared with other irregular shapes, it can more effectively guide the discharge of slag and ash, reduce the residue of slag and ash in the channel, further optimize the slag removal effect, and ensure that the equipment maintains good cleanliness during operation.

[0035] Specifically, the diameter of the circular hole structure is 2-3 mm.

[0036] In this embodiment, the diameter of the circular hole structure is limited to 2-3 mm. This size range is precisely designed to ensure that there is enough space for slag and ash to be discharged to avoid blockage due to too small an aperture, and to prevent the aperture from being too large and affecting the muffler effect.

[0037] Specifically, the slag discharge channel is a groove structure that penetrates the annular step; the groove structure is a semicircular groove structure or a "U"-shaped groove structure or a notch structure.

[0038] In this embodiment, the slag discharge channel can also adopt a groove structure that runs through the annular step as a chip and slag discharge channel, such as a "U"-shaped groove structure or a cutout structure. Its larger opening area has an advantage when processing larger particles of slag ash, and can discharge the slag ash more quickly, thereby improving the slag discharge efficiency. It is particularly suitable for working scenarios with larger slag ash particles or a large amount of slag ash, and can effectively avoid damage to equipment caused by slag ash accumulation.

[0039] Specifically, there are two step rings, which are arranged at intervals on the casing section.

[0040] In this embodiment, two spaced step rings are arranged on the casing section, so that more independent chambers are formed between the silencer jacket and the voltage regulating sleeve of the silencer, thereby further enhancing the silencing effect, being able to more effectively block the propagation of noise, and reducing the noise level generated during the operation of the equipment, thereby providing operators with a quieter and more comfortable working environment, and also helping to improve the applicability of the equipment in noise-sensitive areas.

[0041] Specifically, the pressure regulating hole is arranged between two step rings.

[0042] There are multiple pressure regulating holes, which are matched with the pressure regulating holes on the silencer pipe. The pressure regulating function is achieved by rotating the pressure regulating sleeve to adjust the number of the pressure regulating holes aligned on the silencer pipe.

[0043] Specifically, the clamping step and the step ring are arranged with the same diameter.

[0044] In this embodiment, the compression step has the same diameter as the step ring, and is used to form a closed space with the inner cavity of the silencer jacket of the silencer, so as to better fit with the silencer jacket.

[0045] 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.
