[0029] DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0030] In order to make the obj ective , technical solution and advantages of the present application clearer, the present application is further described in detail below in conj unction with the drawings and embodiments . It should be understood that the speci fic embodiments described herein are only used to explain the present application and are not used to limit the present application .

[0031] In order to solve the technical problem of how to extend the service li fe of the isolater 300 , the present application provides an internal structure of a diaphragm pump heat insulator, which can buf fer the impact of the isolater 300 , thereby extending the service li fe of the isolator . It should be noted that the internal structure of the diaphragm pump heat insulator of the present application is used for but not limited to diaphragm pumps , etc . For the sake of convenience of explanation, in the present application, only the application of the internal structure of the diaphragm pump heat insulator to the diaphragm pump is taken as an example for explanation, and the principle of applying the internal structure of the diaphragm pump heat insulator to other types of equipment is essentially the same as the principle applied to the diaphragm pump, which will not be repeated here .

[0032] Please refer to FIG . 1 , which is a structural schematic diagram of the internal structure of the diaphragm pump insulator in one embodiment of the present application . The internal structure of the diaphragm pump insulator includes a housing 100 , a guide rod 200 , a isolator 300 and two elastic members 400 . The housing 100 has a piston cavity 110 , the guide rod 200 is installed in the piston cavity 110 , the isolator 300 is slidably sleeved on the guide rod 200 , and the two elastic members 400 are respectively arranged at two ends of the guide rod 200 . When the isolator 300 moves to the end of the guide rod 200 and contacts the isolator 300 , the isolator 300 compresses the elastic member 400 to buf fer the impact of the isolator 300 .

[0033] In the present embodiment , the guide rod 200 is mounted in the piston cavity 110 , and the isolater 300 is slidably sleeved on the guide rod 200 , so that the isolater 300 can slide in the piston cavity 110 . Dusleeve ring the use of the diaphragm pump, the isolater 300 will slide back and forth along the guide rod 200 . When the isolater 300 moves to the end of the guide rod 200 , the isolater 300 compresses the elastic member 400 to buf fer the impact of the isolater 300 . Since the impact of the isolater 300 is buf fered by the elastic member 400 , the isolater 300 is prevented from being damaged by frequent severe impacts , thereby extending the service li fe of the isolater 300 .

[0034] In some embodiments , the housing 100 has a mounting part 120 , the elastic member 400 includes a sleeve ring 410 and a first spring 420 , one end of the guide rod 200 is fixed to the mounting part 120 , the sleeve ring 410 is slidably sleeved on the guide rod 200 , one end of the first spring 420 is connected to the sleeve ring 410 , and the other end thereof is connected to the mounting part 120 , and the first spring 420 has an elastic force that pushes the sleeve ring 410 to approach the isolator 300 .

[0035] In this embodiment , when the isolator 300 reaches the end of the guide rod 200 , the isolator 300 presses against the sleeve ring 410 and pushes the sleeve ring 410 to move , and the movement of the sleeve ring 410 overcomes the elastic force of the first spring 420 , thereby playing a role in buf fesleeve ring the isolator 300 .

[0036] Any implementation of the mounting part 120 that can fix the guide rod 200 is feasible . In some embodiments , the mounting part 120 is provided with a mounting hole 121 , and the guide rod 200 is inserted into the mounting hole 121 , so that the guide rod 200 is fixed to the mounting part 120 .

[0037] In this embodiment , since the guide rod 200 is inserted into the mounting hole 121 , the guide rod 200 can be ef fectively prevented from moving radially under the limiting ef fect of the inner wall of the mounting hole 121 , thereby playing a role in fixing the guide rod 200 .

[0038] In some embodiments , the sleeve ring 410 is a ceramic sleeve ring 410 .

[0039] In this embodiment , the ceramic sleeve ring 410 can withstand high temperatures , and can prevent the sleeve ring 410 from being greatly deformed due to thermal expansion and contraction in a high-temperature working environment .

[0040] In some embodiments , the elastic member 400 includes a second spring 430 , which is sleeved on the guide rod 200 and one end of which is connected to the housing 100 . When the isolator 300 moves to the end of the guide rod 200 , the isolator 300 compresses the second spring 430 to buf fer the impact of the isolator 300 .

[0041] In this embodiment , when the isolator 300 moves to the end of the guide rod 200 , the isolator 300 compresses the second spring 430 to buf fer the impact of the isolator 300 .

[0042] It can be understood that the second spring 430 in the aforementioned embodiment can be used as an alternative to the first spring 420 and the sleeve ring 410 .

[0043] In some embodiments , the housing 100 further includes a support part 130 , one end of the guide rod 200 is installed on the support part 130, and one end of the second spring 430 is connected to the support part 130.

[0044] In this embodiment, the support part 130 is used to fix the guide rod 200 on one hand, and to support and fix the second spring 430 on the other hand.

[0045] In some embodiments, the isolator 300 includes an inner sleeve 310 and an outer sleeve 320, wherein the inner sleeve 310 is sleeved on the guide rod 200, and the outer sleeve 320 is sleeved on the outer periphery of the inner sleeve 310.

[0046] In this embodiment, the inner sleeve 310 is slidably sleeved on the guide rod 200, and the outer sleeve 320 is installed on the outer periphery of the inner sleeve 310, wherein the inner sleeve 310 plays a role of sliding and supporting, and the outer sleeve 320 is usually made of a heat-insulating material.

[0047] Based on the above embodiments, in some embodiments, the isolator 300 also includes two buffer pads 330, which are respectively laid at two ends of the inner sleeve 310.

[0048] In this embodiment, since the two buffer pads 330 are respectively laid at two ends of the inner sleeve 310, when the isolator 300 moves to the end of the guide rod 200, not only the elastic member 400 can play a buffesleeve ring role, but the buffer pad 330 can also play a buffesleeve ring role, further improving the buffesleeve ring effect.

[0049] Any flexible buffer pad 330 that can act as a buffer is feasible. In some embodiments, the buffer pad 330 is a rubber buffer pad 330.

[0050] In addition, the present application also provides a diaphragm pump, including the internal structure of the diaphragm pump heat insulator .

[0051] In order to better understand the present application, the technical solution of the present application is described in detail below in conjunction with FIG. 1:

[0052] Guide rod 200 is installed in piston chamber 110, and isolator 300 is slidably sleeved on guide rod 200, so isolator 300 can slide in piston chamber 110. In the operation process of diaphragm pump, isolator 300 can slide back and forth along guide rod 200. When isolator 300 arrives at one end of guide rod 200, isolator 300 can press sleeve ring 410, and promote sleeve ring 410 to move, and the movement of sleeve ring 410 overcomes the elastic force of first spring 420 , thereby plays the ef fect of buf fesleeve ring isolator 300 . When isolator 300 moves to guide rod 200 other end, isolator 300 compresses second spring 430 to buf fer the impact of isolator 300 . Due to buf fesleeve ring isolator 300 impact by elastic member 400 , isolator 300 is avoided to be frequently subj ected to severe impact and damaged, and the service li fe of isolator 300 is extended .

[0053] The speci fic implementation methods of the present application described above do not constitute a limitation on the protection scope of the present application . Any other corresponding changes and modi fications made according to the technical concept of the present application should be included in the protection scope of the claims of the present application .
