Description

[Technical field]

[0001] The utility model relates to the technical field of motors, in particular to a pump shock-absorbing structure. [Background technology]

[0002] At present, the piston in the motor and pump cylinder will generate large vibrations when moving at high speed, which makes the outer shell easy to bump or abut against other mechanical parts when vibrating, and transmit vibrations and generate noise. Therefore, a shock absorbing device is usually required to reduce the vibration of the motor to reduce noise. However, the existing shock absorbing device can usually only reduce vibration in one direction, that is, it can only reduce vibration in the longitudinal direction or in the lateral direction; or it has both lateral and longitudinal shock absorbing functions, but the structure is complicated, resulting in high cost.

[0003] In view of this, it is necessary to provide a pump shock absorbing structure to overcome the above-mentioned defects. [Contents of the utility model]

[0012] In a preferred embodiment, the connecting member includes a guide column, and the guide column is provided with a through hole penetrating the supporting plate; the guide column extends into the corresponding connecting hole so that the supporting plate is pressed onto the connecting plane.

[0013] In a preferred embodiment, the connecting member further comprises a limiting ring which surrounds the guide column at intervals; the limiting ring is arranged around the edge of the connecting plane.

[0014] In a preferred embodiment, limit plates are further provided on both sides of the bearing plate; when the elastic block is in an initial state, the limit plates are spaced apart from the base; when the elastic block is subjected to a preset maximum pressure, the limit plates abut against the base.

[0026] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0027] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0028] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In an embodiment of the present utility model, a pump shock absorbing structure 100 is provided, which is used to perform lateral and longitudinal shock absorption on a load device 200 to reduce noise caused by vibration.

[0030] like Figure 1-Figure 3 As shown, the pump shock absorbing structure 100 includes: a base 10 , a plurality of elastic blocks 20 and a bearing plate 30 .

[0031] The base 10 is a flat plate, which is mainly used to fix on the ground or other equipment. A plurality of fixing holes 11 are provided at the edge of the base 10. Therefore, the base 10 can be connected to the ground or other equipment by setting bolts, rivets, etc. in the fixing holes 11.

[0032] In the embodiment of the present invention, one end of each elastic block 20 is fixed on the base 10. The elastic block 20 is a rubber block or a silicone block, so that the elastic block 20 can absorb vibration by deformation and can also restore to the initial state by its own elasticity.

[0033] In this embodiment, there are four elastic blocks 20 , which are respectively located at four vertices of the same rectangle, so as to improve the stability of the lifting support plate 30 .

[0034] A connection hole 21 is provided at one end of each elastic block 20 away from the base 10. Specifically, the base 10 is provided with an avoidance hole 12 corresponding to the elastic block 20. Each elastic block 20 is in a hollow hemispherical shape, and the edge of the elastic block 20 is arranged around the corresponding avoidance hole 12. Therefore, when the hemispherical elastic block 20 is deformed under pressure, the air in the hemisphere can be discharged through the avoidance hole 12, so as not to affect the deformation of the elastic block 20 under pressure. When the elastic block 20 returns to a hemispherical shape, the external air can also enter the hemispherical space through the avoidance hole 12, thereby avoiding the problem of being unable to return to normal due to the air pressure difference.

[0035] Furthermore, the side of the elastic block 20 away from the base 10 is flattened to form a connection plane 22. The connection plane 22 is arranged parallel to the base 10 and spaced apart. The connection hole 21 is opened in the connection plane 22. It can be understood that the connection plane 22 is a circular surface.

[0036] In the embodiment of the present invention, a connecting piece 31 corresponding to the connecting hole 21 is provided on the side of the load plate 30 close to the base 10. The connecting piece 31 is used to connect with the corresponding connecting hole 21 to install the load plate 30 on the side of the plurality of elastic blocks 20 away from the base 10. It should be noted that the load plate 30 can be a separately provided plate-like structure, or it can be reused for some components of the load device 200.

[0037] Specifically, the connecting member 31 includes a guide column 311. The guide column 311 extends into the corresponding connecting hole 21 so that the bearing plate 30 is pressed onto the connecting plane 22. The guide column 311 will not be separated from the corresponding connecting hole 21 due to the gravity of the bearing plate 30 itself. Furthermore, the guide column 311 is provided with a through hole 312 that penetrates the bearing plate 30. Therefore, a bolt can be screwed into the through hole 312, and then a nut can be set in the hemispherical space of the elastic block 20, and the area of ​​the nut is larger than the area of ​​the connecting hole 21, so as to further prevent the guide column 311 from being separated from the connecting hole 21, thereby improving the reliability of the connection.

[0038] Furthermore, the connecting member 31 further includes a limiting ring 313 which is spaced around the guide column 311. The area enclosed by the limiting ring 313 is slightly larger than the full level of the connecting plane 22, so that the limiting ring 313 is enclosed at the edge of the connecting plane 22, thereby effectively preventing the load-bearing plate 30 and the elastic block 20 from lateral movement.

[0039] Furthermore, limit plates 32 are provided on both sides of the load-bearing plate 30. The limit plates 32 are extended in a direction close to the base 10. When the elastic block 20 is in an initial state (i.e., when the load device 200 is not in operation), the limit plates 32 are spaced apart from the base 10. When the elastic block 20 is subjected to a preset maximum pressure (i.e., the maximum shock-absorbing capacity of the elastic block 20 is reached), the limit plates 32 abut against the base 10, thereby preventing the vibration of the load device 200 from further pressing the elastic block 20, preventing the elastic block 20 from producing irreversible deformation, and thereby improving the service life of the elastic block 20.

[0040] In summary, the pump shock-absorbing structure 100 provided by the utility model can meet both longitudinal and lateral shock-absorbing requirements by arranging a plurality of elastic blocks 20 between the base 10 and the bearing plate 30 , and has a simple structure, thereby reducing costs.

[0041] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
