Description

Technical Field

[0001] The utility model relates to the technical field of rubber pads, in particular to a rubber pad structure. Background Art

[0002] Rubber pads have a large shear deformation capacity. In automobiles, elevators, ships and other equipment, rubber pads can also be used to support, fix and cushion mechanical equipment to prevent track loosening, vibration and damage, as well as reduce coaxial friction and extend the service life of the equipment.

[0003] Although the commonly used rubber pads have good supporting performance, due to their integrated structure, when the extrusion pressure changes, they will be extruded and deformed, and the overall cross-sectional size will expand outward. In the use scenario where there is no space for deformation expansion, the rubber pads will be hard squeezed and the aging of the rubber pads will be accelerated. Utility Model Content

[0004] Technical issues solved

[0005] In view of the deficiencies of the prior art, the utility model provides a rubber pad structure whose overall cross section will not expand outward when the extrusion pressure changes.

[0008] The extrusion resistance component comprises a fixing seat installed at the bottom end of the upper butt-jointed petal and the top end of the lower contact pad, wherein the fixing seats are grouped in pairs, and an extrusion sheet is rotatably installed between the fixing seats in a group.

[0009] Preferably, the interval between two adjacent lower docking flaps is adapted to the size of the upper docking flap, and the interval between two adjacent upper docking flaps is adapted to the size of the lower docking flap. The lower contact pad and the upper contact pad are clamped together through the lower docking flaps and the upper docking flaps, which can produce relative sliding during squeezing without causing the middle part to expand and deform outward.

[0010] Preferably, a docking port cooperating with the guide portion is opened in the middle of the upper contact pad, and the upper contact pad is slidably connected to the guide portion, so that when extrusion and contraction occur at the lower contact pad and the upper contact pad, the guide portion can be used to play a role of stable guidance.

[0011] Preferably, the extrusion sheet is arc-shaped, the extrusion sheet is made of elastic material, and there is a spacing distance between the arc surface of the extrusion sheet and the guide portion.

[0012] Preferably, a mounting hole begins at the top end of the guide portion, and the mounting hole passes through to the bottom end of the lower contact pad for installation of the present design.

[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model provides a rubber pad structure with the following beneficial effects: by arranging the lower docking petals, the upper docking petals and the extrusion resistance component, the relative sliding of the lower docking petals and the upper docking petals can be utilized to avoid the outward expansion of the middle part due to the extrusion force, avoid the accelerated aging of the rubber pad due to hard extrusion, and provide a force to resist extrusion. When the deformation reaches a certain degree, the guide part will block the continued deformation, thereby realizing the control of the overall extrusion degree of the present design.

[0021] See also Figure 1-4 , the utility model provides a technical solution of a rubber pad structure:

[0022] Embodiment: A rubber pad structure comprises a lower contact pad 1, the top outer ring of the lower contact pad 1 is evenly arrayed with six lower docking petals 12, the top inner ring of the upper contact pad 11 is connected with a guide portion 14, the outer wall of the guide portion 14 is sleeved with the upper contact pad 11, the bottom end of the upper contact pad 11 is evenly arrayed with six upper docking petals 13, and the bottom end of the upper docking petal 13 is provided with an extrusion resistance component;

[0023] The extrusion resistance component includes a fixing seat 2 installed at the bottom end of the upper docking flap 13 and the top end of the lower contact pad 1. The fixing seats 2 are grouped in pairs. An extrusion sheet 21 is rotatably installed between a group of fixing seats 2. The interval between two adjacent lower docking flaps 12 is adapted to the size of the upper docking flap 13, and the interval between two adjacent upper docking flaps 13 is adapted to the size of the lower docking flap 12. The lower contact pad 1 and the upper contact pad 11 are clamped together through the lower docking flap 12 and the upper docking flap 13, so that relative sliding can occur during extrusion without causing the middle to move. Outward expansion deformation, a docking port 15 cooperating with the guide portion 14 is opened in the middle of the upper contact pad 11, and the upper contact pad 11 is slidably connected to the guide portion 14. When extrusion and contraction occur at the lower contact pad 1 and the upper contact pad 11, the guide portion 14 can be used to play a role of stable guidance. The extrusion sheet 21 is arc-shaped, and the extrusion sheet 21 is made of elastic material. There is a spacing distance between the arc surface of the extrusion sheet 21 and the guide portion 14. A mounting hole 16 begins to be provided at the top end of the guide portion 14, and the mounting hole 16 passes through to the bottom end of the lower contact pad 1 for the installation of this design.

[0024] During specific use, the utility model provides a rubber pad structure. After the extrusion pressure is generated at the lower contact pad 1 and the upper contact pad 11, the relative sliding of the lower docking petal 12 and the upper docking petal 13 can be used to avoid the middle part from expanding outward due to the extrusion pressure. When the lower docking petal 12 and the upper docking petal 13 slide relative to each other, the extrusion will cause the extrusion sheet 21 to deform, and the extrusion sheet 21 can be used to provide a force to resist the extrusion. At the same time, by using the distance between the extrusion sheet 21 and the guide portion 14, when the deformation of the extrusion sheet 21 reaches a certain degree, the guide portion 14 will block the continued deformation of the extrusion sheet 21.

Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
