Description

Technical Field

[0001] The utility model relates to the technical field of internal anti-vibration sealing pads for fitness equipment, in particular to an internal anti-vibration sealing pad for fitness equipment. Background Art

[0002] Fitness equipment is often divided into two categories according to the number of training functions: single-function and comprehensive multi-function. Commonly used ones include rowing machines, fitness bikes, steppers, treadmills, waist beautifying machines, etc. Their main function is to increase arm strength. For example, dumbbells, hand grippers and multi-function sit-up boards. Rowing machines are mainly used to enhance arm strength, latissimus dorsi and movement coordination ability. Comprehensive multi-function machines generally include chest expanders, pull-ups, bench presses, sit-ups and other equipment functions. Chest expanders, pull-ups and bench presses are mainly used to exercise upper limb strength and pectoralis major strength. Sit-ups are mainly used to exercise the psoas muscles and reduce excess fat in the waist and abdomen. Sealing pads are needed inside. Sealing pads are a material used for sealing inside machinery, equipment, pipelines, etc.

[0003] The prior art has the following deficiencies: the sealing gasket in the prior art cannot be in close contact with the connecting piece during use, resulting in poor sealing effect of the sealing gasket. In addition, the sealing gasket will be damaged under long-term extrusion, and its toughness is poor, the service life is short, and its function is relatively single, which only plays a sealing role. Considering that it still has many defects in waterproofness, stability, and shockproofness, we propose an internal shock-resistant sealing gasket for fitness equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an internal seismic sealing pad for fitness equipment, which has the advantages of good shock absorption and good toughness, and solves the problems of poor sealing effect and single function.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal seismic sealing pad of fitness equipment, comprising a lower connecting pad, the top of the lower connecting pad is movably connected with a sealing pad body, the bottom of the sealing pad body is provided with a connecting groove, the top of the lower connecting pad is fixedly connected with a buffer cabin, the interior of the connecting groove is fixedly connected with a supporting cabin, the interior of the supporting cabin is fixedly connected with a seismic structure, the outer surface of the sealing pad body is fixedly connected with a reinforcement layer, the outer surface of the reinforcement layer is fixedly connected with a fireproof layer, the outer surface of the fireproof layer is fixedly connected with a waterproof layer, the interior of the sealing pad body is fixedly connected with a wear-resistant layer, the top of the wear-resistant layer is provided with a limiting groove, the interior of the sealing pad body is provided with a through hole, and the interior of the through hole is provided with a threaded groove;

[0006] The earthquake-resistant structure includes an earthquake-resistant base, the inner bottom wall of the buffer cabin is fixedly connected to the earthquake-resistant base, the interior of the earthquake-resistant base is fixedly connected to a limiting base, the top of the earthquake-resistant base is fixedly connected to an earthquake-resistant spring, the top of the earthquake-resistant spring is fixedly connected to a buffer plate, the bottom of the buffer plate is fixedly connected to a limiting rod, and the bottom of the limiting rod is fixedly connected to a rubber sleeve.

[0007] Furthermore, the top of the buffer cabin is fixedly connected to a limiting ring, the interior of the buffer cabin is movably connected to a supporting cabin, and the supporting cabin is connected to a lower connecting pad through the buffer cabin.

[0008] Furthermore, the outer sides of the sealing pad body and the lower connecting pad are fixedly connected with a reinforcing layer, a fireproof layer and a waterproof layer, and the radius of the connecting groove is larger than the radius of the supporting cabin.

[0009] Furthermore, the sealing pad body and the lower connecting pad are both provided with through holes inside, and the wear-resistant layer is made of asbestos rubber layer.

[0010] Furthermore, the inner radius of the limiting base is matched with the radius of the limiting rod, and the inner bottom wall of the limiting base is fixedly connected with an ultra-fine sponge.

[0011] Furthermore, four anti-seismic springs are fixedly connected to the top of the anti-seismic base and are equidistantly distributed around the circumference. Reinforcing ribs are fixedly arranged inside the anti-seismic springs.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The internal seismic sealing gasket of the fitness equipment is provided with a seismic structure, so that a certain rebound is generated on the sealing ring body during the daily use of the sealing gasket, so that the sealing gasket and the connecting piece are in close contact with each other. At the same time, the internal connection reinforcing ribs of the seismic spring are provided, so that the sealing gasket body can transmit faster when subjected to external forces. The seismic spring can quickly disperse the external force to the buffer cabin and the support cabin, and through the setting of multi-stage seismic springs, the seismic resistance is fully exerted, the life of the energy consumption unit is extended, and the vibration of the seismic base is better resisted. In addition, considering that long-term wear will lead to aging of the sealing gasket body, the poor sealing of the sealing gasket body is avoided. The rubber sleeve provided at the bottom of the limit rod not only increases the service life of the sealing gasket body, but also further reduces the maintenance cost.

[0014] 2. The internal anti-seismic sealing gasket of the fitness equipment is provided with a reinforcement layer and a waterproof layer, and the reinforcement layer is made of graphite. Since graphite has high stability and excellent sealing performance, and in daily use, when there is a large force pulling or vibration, the graphite can withstand the drastic temperature change without being damaged when used at room temperature. When the temperature suddenly changes, the volume of the graphite does not change much and no cracks will occur. At the same time, since a polytetrafluoroethylene gasket is provided between the waterproof layer and the fireproof layer, the layer-by-layer structure has a stronger anti-corrosion performance and higher sealing resilience. By providing a threaded groove, the sealing gasket and the connector can be connected by rotation, avoiding the pulling of the sealing gasket by the sleeve-in type, thereby affecting the sealing performance of the sealing gasket.
