[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-6 As shown, the utility model provides a muffler structure with double silencers, including a muffler body 1, both ends of the muffler body 1 are respectively threadedly connected with a reinforcement ring 2, the outer walls of the muffler body 1 and the reinforcement ring 2 are provided with a plurality of jacks, the interiors of the two reinforcement rings 2 are fixedly installed with two mounting boxes 201, the inner walls of the mounting boxes 201 are provided with a return spring 202, the jacks are connected to the mounting boxes 201, and a latch 7 is provided in the jacks, the outer wall of the muffler body 1 is fixedly installed with two sleeve clamps 5, the sleeve clamps 5 A receiving groove 502 is provided at one end, a hole 503 is provided in the receiving groove 502, and an extrusion mechanism 6 is provided. The extrusion mechanism 6 includes a sliding snap ring 601, two extrusion arc plates 602, a guide rod 603 and a compression spring 605. The guide rod 603 drives the two extrusion arc plates 602 to slide on the outer wall of the muffler body 1 through the sliding snap ring 601. The compression spring 605 is sleeved on the guide rod 603. The two extrusion arc plates 602 are respectively against a number of pins 7, and the two reinforcement rings 2 are both slidably matched with the muffler body 1.

[0025] After docking the two reinforcement rings 2 with the muffler body 1, the staff first aligns the sockets opened on the outer walls of the two, and then pulls the guide rod 603. After the guide rod 603 moves, it drives the sliding snap ring 601 to move and squeezes the compression spring 605. When the sliding snap ring 601 moves, it slides with the receiving groove 502 and the outer wall of the muffler body 1, and drives the two extrusion arc plates 602 to move. After the two extrusion arc plates 602 move a certain distance, the staff inserts the pin 7 into the socket between the two. After several pins 7 slide a certain distance in the two sockets, they can squeeze the reset spring 202, so that the reset spring 202 is in In the extruded state, after the latch 7 is fully inserted into the muffler body 1, the staff releases the guide rod 603. At this time, the compression spring 605 releases the pressure and drives the guide rod 603, the sliding clamp 601, the two extrusion arc plates 602 and the fixing block 604 to move to the initial position. At this time, the two extrusion arc plates 602 can squeeze the corresponding latch 7, so that the latch 7 is tightly inserted into the insertion holes of the muffler body 1 and the reinforcement ring 2, and the muffler body 1 and the reinforcement ring 2 are fixed. The installation method is simple and multiple parts can be installed at the same time, reducing the time required for installing a single part, thereby improving work efficiency and applicability.

[0026] When the reinforcement ring 2 and the muffler body 1 need to be separated, the staff manually pulls the guide rod 603. After the guide rod 603 moves, it drives the two extrusion arc plates 602 to move through the sliding clamp ring 601, so that the two extrusion arc plates 602 no longer squeeze the latch 7. At this time, the return springs 202 release the pressure and push the latch 7 in the opposite direction, so that the latch 7 is disengaged from the insertion holes of the muffler body 1 and the reinforcement ring 2, thus completing the disassembly. The disassembly operation is simple and does not require the repeated rotation of the screw, further improving work efficiency.

[0027] like Figure 2-3 As shown, in one embodiment, when the latch 7 is fully inserted into the insertion hole, the return spring 202 is in a squeezed state, and the latch 7 is in sliding engagement with the insertion hole defined by the muffler body 1 and the reinforcement ring 2 .

[0028] When the extrusion arc plate 602 no longer squeezes the latch 7, the plurality of return springs 202 release the pressure to push the latch 7 out of the insertion hole, which simplifies the disassembly method and improves the applicability.

[0029] like Figure 3-5As shown, in one embodiment, the extrusion mechanism 6 also includes a fixed block 604, the guide rod 603 is slidably matched with the hole 503, the fixed block 604 is fixedly installed at one end of the guide rod 603, the sliding snap ring 601 is fixedly sleeved on the guide rod 603, and the two extrusion arc plates 602 are respectively fixedly connected to the two ends of the sliding snap ring 601, and the two ends of the compression spring 605 are respectively connected to the fixed block 604 and the sleeve snap ring 5. When the guide rod 603 moves, the compression spring 605 is also squeezed. The extrusion mechanism 6 also includes a handle 606, which is fixedly installed at the other end of the guide rod 603.

[0030] The fixing block 604 is used to install the compression spring 605 and limit the guide rod 603 to prevent the guide rod 603 from escaping from the hole 503, thereby improving the structural stability. The handle 606 can facilitate the staff to pull the guide rod 603, further improving the applicability.

[0031] like Figure 6 As shown, in one embodiment, a protective tube 501 is fixedly mounted on one end of the sleeve clamp 5 , a fixing block 604 is slidably fitted with the inner wall of the protective tube 501 , and a diameter of the fixing block 604 is larger than a diameter of the hole 503 .

[0032] The protective tube 501 is used to protect the compression spring 605, prevent the compression spring 605 from being easily damaged, and extend the service life of the equipment.

[0033] like Figure 1-2 As shown, in one embodiment, the inner wall of the muffler body 1 is provided with sound-absorbing cotton, one end of the two reinforcement rings 2 is respectively threadedly connected with the protective cover 3 and the flange 8, the inner wall of the flange 8 is fixedly installed with an air inlet pipe 101, the inner wall of the muffler body 1 is fixedly installed with a sound absorbing panel 102 and a sound absorbing panel 2 104, one end of the sound absorbing panel 102 is fixedly installed with a plurality of guide pipes 103, and the plurality of guide pipes 103 all pass through the sound absorbing panel 102, and one end of the sound absorbing panel 2 104 is fixedly installed with an air outlet pipe 100, and the two ends of one of the guide pipes 103 are respectively aligned with the air inlet pipe 101 and the air outlet pipe 100, the first expansion chamber is between the flange 8 and the sound absorbing panel 102, and the second expansion chamber is between the sound absorbing panel 102 and the sound absorbing panel 2 104.

[0034] The muffler body 1, the sound-absorbing cotton, the air outlet pipe 100, the air inlet pipe 101, the second sound-absorbing panel 104, the first sound-absorbing panel 102, the plurality of flow guide pipes 103, the first expansion chamber and the second expansion chamber are all prior art and are not explained here.

[0035] The protective cover 3 is used to protect the air outlet pipe 100, improve the protection effect of the equipment, and extend the service life of the equipment. The flange 8 is used to fix the air inlet pipe 101 and the reinforcement ring 2 to improve the structural stability.

[0036] The following is a detailed description of the working principle of the muffler structure with double silencer:

[0037] After docking the two reinforcement rings 2 with the silencer body 1, the staff first aligns the sockets opened on the outer walls of the two, and then pulls the guide rod 603 through the handle 606. After the guide rod 603 moves, it drives the sliding snap ring 601 and the fixed block 604 to move. When the fixed block 604 moves, it cooperates with the sleeve snap ring 5 and squeezes the compression spring 605. When the sliding snap ring 601 moves, it slides with the receiving groove 502 and the outer wall of the silencer body 1, and drives the two extrusion arc plates 602 to move. After the two extrusion arc plates 602 move a distance, the staff inserts the pin 7 into the socket between the two. After several pins 7 slide a distance in the two sockets, they can squeeze and compress. The reset spring 202 is positioned so that the return spring 202 is in an extruded state. Then, after the latch 7 is fully inserted into the muffler body 1, the staff releases the grip 606. At this time, the compression spring 605 releases the pressure and drives the guide rod 603, the sliding snap ring 601, the two extrusion arc plates 602 and the fixing block 604 to move to the initial position. At this time, the two extrusion arc plates 602 can squeeze the corresponding latch 7, so that the latch 7 is tightly inserted into the insertion holes of the muffler body 1 and the reinforcement ring 2, and the muffler body 1 and the reinforcement ring 2 are fixed. The installation method is simple, multiple parts can be installed at the same time, and the time required for installing a single part is reduced, thereby improving work efficiency and applicability.

[0038] When the reinforcement ring 2 and the muffler body 1 need to be separated, the staff manually pulls the guide rod 603. After the guide rod 603 moves, it drives the two extrusion arc plates 602 to move through the sliding clamp ring 601, so that the two extrusion arc plates 602 no longer squeeze the latch 7. At this time, the return springs 202 release the pressure and push the latch 7 in the opposite direction, so that the latch 7 is disengaged from the insertion holes of the muffler body 1 and the reinforcement ring 2, thus completing the disassembly. The disassembly operation is simple and does not require the repeated rotation of the screw, further improving work efficiency.

[0039] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
