Description

Technical Field

[0001] The utility model relates to the technical field of compressor fitting production and processing, and more specifically, to a bracket for opening a hole in a silencer cover plate. Background Art

[0002] The compressor exhaust silencer is a new generation of noise reduction products. Based on the principle of large-hole pressure-reducing injection silencer, through optimized design, its noise reduction index, safety performance and service life are far superior to similar products on the market, and can better meet the noise reduction needs of various compressor exhausts in industries such as electricity, metallurgy, petroleum, chemical industry, textile, papermaking, and food. The existing silencer is equipped with a silencer cover at its outlet, and then a copper pipe is connected to the silencer cover to further achieve its exhaust.

[0003] For example, the authorization announcement number CN219311455U discloses a special support member for opening a hole in a silencer cover plate. The truncated cone structure of the top member is set according to the inner wall contour of the silencer cover plate to support the silencer cover plate and avoid deformation of the cover plate when opening a hole in the side wall of the silencer cover plate. When drilling holes, since the top member is provided with a groove, the drill bit can directly penetrate the silencer cover plate and extend into the groove. The groove provides a movable space for the drill bit, and the marking and positioning of the opening position is achieved through the groove on the cover seat.

[0004] In the above scheme, the support member is connected to the frame through threads. This method requires opening a threaded hole in the frame that matches the support member. Since the position of the threaded hole is fixed, the support member cannot be moved at will, which has great limitations and may also cause damage to the frame. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a bracket for opening a hole in a silencer cover plate, which can achieve connection between a frame and a support member without opening a hole in the frame.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bracket for opening a hole in a cover plate of a sound-absorbing bag comprises a top piece and a base placed below the top piece, the base and the top piece are both provided with grooves for opening the cover plate, a connecting steel belt is provided on the lower end surface of the base, and the connecting steel belt is detachably connected to the base.

[0008] The connecting steel belt includes a plurality of hinged connecting plates, and a cavity is provided in the base for the connecting plates to pass through.

[0009] The cross section of the cavity is inverted L-shaped, and the cavity diameter is adapted to the diameter of the connecting plate.

[0010] The inner wall of the cavity is provided with a number of equidistantly arranged convex teeth, and the two side walls of the connecting plate are provided with docking teeth engaged with the convex teeth. The convex teeth and the docking teeth are elastic. A pull rope for stretching the connecting plate into the cavity is provided at the end of the connecting steel belt, and the pull rope is elastic.

[0011] The utility model is further configured as follows: two fixed blocks are provided on the lower end surface of the base, threaded holes are provided on the side walls of the fixed blocks, a connecting steel belt is placed between the two fixed blocks, a docking hole is provided on the side wall of the connecting steel belt, threads are provided in the docking hole, and the connecting steel belt is connected to the fixed block by extending a screw rod into the threaded hole and the docking hole.

[0012] The utility model is further configured as follows: a protrusion is provided on the side wall of the connecting plate, a positioning hole is opened on the protrusion, and a screw is fixedly connected to the end of the pull rope, and the connecting plate passing through the cavity is further limited by the screw.

[0013] The utility model is further configured as follows: a sponge sheet is arranged on the lower end surface of the base, a rubber sheet is adhered to the end surface of the sponge sheet, and a plurality of anti-slip convex points are arranged on the end surface of the rubber sheet.

[0014] Compared with the shortcomings of the prior art, the beneficial effects of the utility model are:

[0015] By setting a connecting steel belt, the bracket is fixed on different frames through the connecting steel belt. At the same time, the connecting steel belt and the base are connected by threads. Since the docking teeth and the convex teeth are in opposite directions, when the docking teeth on the connecting steel belt are engaged with the convex teeth, the connecting steel belt is fixed in the cavity. When the bracket needs to be displaced, it is only necessary to remove the connecting steel belt from the base and pull the connecting steel belt out of the cavity. Furthermore, a sponge sheet and a rubber sheet are provided on the lower end surface of the base to increase the friction between the base and the frame, making the connection more stable. The easily deformable sponge sheet is suitable for frames of various specifications. The position of the bracket can be changed without punching holes in the frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figures 1 to 3 As shown,

[0023] A bracket for opening a hole in a cover plate of a silencer bag comprises a top member 1 and a base 2 placed below the top member 1. Grooves for opening the cover plate are provided on the base 2 and the top member 1. A connecting steel belt 3 is provided on the lower end surface of the base. A sponge sheet 11 is provided on the lower end surface of the base 2. A rubber sheet 12 is adhered to the end surface of the sponge sheet 11. A plurality of anti-slip bumps 13 are provided on the end surface of the rubber sheet 12 to increase the friction between the base and the frame.

[0024] The connecting steel belt is detachably connected to the base. There are two fixed blocks 9 on the lower end face of the base 2. The side walls of the fixed blocks 9 are provided with threaded holes. The connecting steel belt 3 is placed between the two fixed blocks 9. The side walls of the connecting steel belt are provided with docking holes. The docking holes are provided with threads. The connecting steel belt 3 is connected to the fixed blocks 9 by extending screws into the threaded holes and the docking holes. The screws are used to realize quick assembly and quick disassembly of the connecting steel belt 3 and the base 2.

[0025] The connecting steel belt 3 includes a plurality of hinged connecting plates 4. A cavity 5 is provided in the base 2 for the connecting plate 4 to pass through. The cross section of the cavity 5 is an inverted L shape. The diameter of the cavity 5 is adapted to the diameter of the connecting plate 4. The inner wall of the cavity 5 is provided with a plurality of equidistantly arranged convex teeth 6. Both side walls of the connecting plate 4 are provided with docking teeth 7 that are engaged with the convex teeth 6. The convex teeth 6 and the docking teeth 7 are elastic. The convex teeth 6 are in opposite directions to the engaging teeth. The fixing of the connecting steel belt 3 to the wall is achieved by docking the convex teeth 6 with the engaging teeth.

[0026] A pull rope 8 for pulling the connecting plate 4 into the cavity 5 is provided at the end of the connecting steel belt 3. The pull rope 8 is elastic. A protrusion 10 is provided on the side wall of the connecting plate 4. A positioning hole is opened on the protrusion 10. A screw is fixedly connected to the end of the pull rope 8. The connecting plate 4 passing through the cavity 5 is further limited by the screw. After the connecting steel belt 3 passes through the cavity 5, one end of the connecting steel belt 3 passes through the cavity 5, and the screw on the pull rope 8 is connected to the positioning hole on the protrusion 10 to achieve further limitation of the connecting steel belt 3 and prevent the connecting steel belt 3 from being displaced due to force.

[0027] Working principle: when the bracket needs to be fixed, make the lower end surface of the base 2 contact with the frame, then pass the pull rope 8 through the cavity 5, pull the pull rope 8, because the docking teeth 7 at both ends of the connecting plate 4 are adapted to the size of the convex teeth 6 inside the cavity 5 and in opposite directions, it is difficult to pull out once installed, thereby ensuring the stability of the bracket until the base 2 is firmly fixed on the frame, then insert the screw on the pull rope 8 into the protrusion 10 on the connecting plate 4 at the exit of the cavity 5, and further limit the connecting steel belt 3. Since the sponge sheet 11 has the ability to deform, it can fit with the frame to ensure the stability of the connection. When the bracket needs to be disassembled, remove the connecting steel belt 3 from the fixing block 9, then pull the connecting steel belt 3 out of the cavity 5, remove the bracket from the frame, and then fix the connecting steel belt 3 to the base 2, and move the bracket to other positions through the above operations.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
