Description
本創作係有關於一種避震結構，尤指一種手推車之輪體避震結構。 This creation department is concerned with a suspension structure, especially a wheel suspension structure of a trolley.
按，一般經常使用手推車進行各種貨物的搬運，但由於傳統的手推車構造僅於車台底部設置有四組車輪，礙於空間而無法另外設置相關的避震結構，故不具有避震效果。當用來運送一些較精密或易碎的物品時，而有可能因為無法緩衝振動時的衝擊力道，造成物品損壞。因此，市面上具有一種避震結構，請配合參閱第9、10圖所示，該避震結構40包含：一座體41，該座體41中容置有一端向外凸伸之伸縮桿42，該伸縮桿42在座體內之一端上置設有第一彈性元件43，該第一彈性元件43另一端並抵靠在與座體41結合在一起之底板44內壁上，且該第一彈性元件座431套合有一第二彈性元件45，該第二彈性元件45一端固定在底板44之內壁上，俾使用時，可將伸縮桿42向外凸伸出之一端鎖固於任一推車上，當使用推車時，其承載重量不同而壓縮不等數量之該等彈簧，重量較輕時僅會壓縮單一彈簧，並可根據承載的重量增加而漸次壓縮一個或多個彈簧，而達到自動調節回復彈力之功效。然而，實際使用時，前述之該避震結構40如使用線徑太大之彈簧則會成強度過大，於載重不足的狀態下會喪失避震效果；反之，如使用 線徑太小之外側彈則整體結構的強度較弱，故容易被壓縮而提早與內側彈簧密接，使外側彈簧的各簧圈緊密靠接，同樣喪失其應有的避震效果，以上皆會導致震動直接傳導至推車上，造成裝載物品的碰撞損壞者，為習知之該避震結構使用時的缺陷，故有必要加以改良。 According to the general, the trolley is often used for carrying various goods. However, since the conventional trolley structure is provided with only four sets of wheels at the bottom of the platform, the related suspension structure cannot be separately provided due to the space, so there is no shock absorber effect. When used to transport some delicate or fragile items, it may cause damage to the items due to the inability to cushion the impact of vibration. Therefore, there is a suspension structure on the market. Please refer to the figures 9 and 10, the suspension structure 40 includes a body 41, and the base 41 houses a telescopic rod 42 protruding outwardly from one end. The telescopic rod 42 is disposed at one end of the housing body with a first elastic member 43. The other end of the first elastic member 43 abuts against the inner wall of the bottom plate 44 combined with the seat body 41, and the first elastic member seat The 431 sets are combined with a second elastic element 45. One end of the second elastic element 45 is fixed on the inner wall of the bottom plate 44. When used, the telescopic rod 42 can be bent outwardly to one of the carts. When the cart is used, the springs of different weights and compressions are compressed. When the weight is light, only a single spring is compressed, and one or more springs can be gradually compressed according to the weight of the load, and the automatic is achieved. Adjust the effect of restoring elasticity. However, in actual use, the shock absorber structure 40 described above may have an excessive strength if a spring having a large wire diameter is used, and the suspension effect may be lost in a state where the load is insufficient; If the wire diameter is too small, the outer structure of the outer side is weak, so it is easy to be compressed and close to the inner spring early, so that the outer coils of the outer spring are closely connected, and the same shock absorber effect is also lost. The vibration is directly transmitted to the cart, and the collision damage of the loaded article is a defect in the use of the conventional suspension structure, so it is necessary to improve it.
有鑑於此，本創作人於多年從事相關產品之製造開發與設計經驗，針對上述之目標，詳加設計與審慎評估後，終得一確具實用性之本創作。 In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The upper surface of the upper end of the upper end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end of the lower end Finally, a chassis 14 is fitted into the snap ring groove 115 embedded in the inner side of the lower interface 112, so that the interface 112 of the buffer body 11 is closed, and the effect of the compression buffer can be achieved through the vent hole 141 of the chassis 14. The above structure is used to complete a wheel suspension structure of a trolley.
其結構實際使用之狀態，續請參閱第5圖配合第6、7、8圖所示，該避震結構10係以頂座12配合組設於推車20底部，再以底座13疊設於腳輪30上方，又該些腳輪30可先組設於一銜接支架31底部，再透過銜接支架31與該些避震結構10組接，令該些腳輪30不僅能經由該銜接支架31相互連結，進而同步且平均受到該些避震結構10所提供之緩衝效果，另一方面也能反向提供推車20更佳之吸震效果，提升推車20裝載精密物品的穩定性，綜上所述，當推車20被推動並以底部之腳輪30滑行位移時，其腳輪30經過不平路段而有震動、顛簸情況產生，俾能透過避震結構10達到吸震、緩衝效果，且該避震結構10主要以中空筒體之緩衝體11達到支撐效果，更於緩衝體11底部之底盤14設有一透氣孔141，令緩衝體11不僅能確實達到支撐推車20重量的效果，另一方面受力壓縮變形時，還能利用透氣孔141將腔內空氣排出達到 緩衝吸震效果，大幅降低推車20之震動產生，又該緩衝體11中斷處更頸縮具有一支撐部116，當推車因轉向產生側傾時的晃動情況時，則能再透過支撐部116達到側向緩衝效果，增添推車行進路程之穩定性者。 For the actual use of the structure, please refer to FIG. 5 for the sixth, seventh, and eighth drawings. The suspension structure 10 is assembled with the top seat 12 at the bottom of the cart 20, and then stacked on the base 13 Above the casters 30, the casters 30 can be assembled on the bottom of a connecting bracket 31, and then connected to the suspension structures 10 through the connecting brackets 31, so that the casters 30 can not only be connected to each other via the connecting brackets 31. In turn, the buffering effect provided by the suspension structures 10 is synchronized and on average, and on the other hand, the shock absorption effect of the cart 20 can be provided in the reverse direction, and the stability of loading the precision items of the cart 20 is improved. When the cart 20 is pushed and displaced by the bottom caster 30, the caster 30 is vibrated and bumped by the uneven section, and the shock absorber and the cushioning effect are achieved through the shock absorbing structure 10, and the suspension structure 10 is mainly The buffer body 11 of the hollow cylinder reaches the supporting effect, and the vent hole 141 is provided on the bottom plate 14 of the bottom of the buffer body 11, so that the buffer body 11 can not only achieve the effect of supporting the weight of the cart 20, but also compressively deformed under force. Can also use venting holes 141 discharge the air in the cavity to reach The cushioning shock absorbing effect greatly reduces the vibration of the cart 20, and the cushioning body 11 is more necked at the interruption to have a supporting portion 116. When the cart is shaken due to the tilting of the steering, the bracket 116 can be re-transmitted through the supporting portion 116. Achieve lateral cushioning and increase the stability of the cart's travel distance.
