The engaging portions 411 and 421 of the sleeve 41 and the second self-lubricating sleeve 42 may be any shape that can be fitted to each other. Not limited to this.
該墊片5套設於該心軸3且被限位於該第二自潤軸套42外緣與該心軸3的限位凸緣321間。The spacer 5 is sleeved on the mandrel 3 and is limited between the outer edge of the second self-lubricating sleeve 42 and the limiting flange 321 of the mandrel 3.
該阻擋蓋6設置於該踏板本體2，用以遮蓋該軸孔201於該套管20第二端203的開口。The blocking cover 6 is disposed on the pedal body 2 to cover the opening of the shaft hole 201 at the second end 203 of the sleeve 20 .
裝設本實施例之自行車踏板時，先將該自潤軸套單元4穿設於該踏板本體2，再將該心軸3穿設入該自潤軸套單元4及該踏板本體2並套入該墊片5，接著如圖4、圖5及圖6所示，使用一具有一壓槽91的沖壓件9於該心軸3的限位端32沖壓出該限位凸緣321。When the bicycle pedal of the embodiment is installed, the self-lubricating sleeve unit 4 is first inserted into the pedal body 2, and the mandrel 3 is inserted into the self-lubricating sleeve unit 4 and the pedal body 2. Into the spacer 5, and then as shown in FIGS. 4, 5 and 6, the limiting flange 321 is punched out at the limiting end 32 of the mandrel 3 by means of a stamping member 9 having a pressure groove 91.
於本實施例中，該沖壓件9的壓槽91為正六邊形，故所沖壓出的限位凸緣321亦為正六邊形，但亦可為圓形、正多邊形或均勻對稱的任意形狀，並不限於此。In this embodiment, the pressing groove 91 of the stamping member 9 is a regular hexagon, so the stamped flange 321 is also a regular hexagon, but may also be a circular shape, a regular polygon or a uniform shape. Not limited to this.
參閱圖2及圖3，沖壓完成後，再將該阻擋蓋6蓋上，即完成組裝。Referring to FIG. 2 and FIG. 3, after the stamping is completed, the blocking cover 6 is covered, that is, the assembly is completed.
經由以上的說明，可將本實施例的優點歸納如下：Through the above description, the advantages of this embodiment can be summarized as follows:
一、藉由使用該第一自潤軸套41及該第二自潤軸套42取代習知技術中的滾珠軸承，可以減少元件的複雜度，減輕重量，降低製造上的成本。1. By using the first self-lubricating bushing 41 and the second self-lubricating bushing 42 to replace the ball bearing in the prior art, the complexity of the component can be reduced, the weight can be reduced, and the manufacturing cost can be reduced.
二、由於該心軸3只與該第一自潤軸套41及該第二自潤軸套42接觸，且該第一自潤軸套41及該第二自潤軸套42嵌合於該第一卡合部204及該第二卡合部206，並不會隨該心軸3轉動而連動，因此只有該第一自潤軸套 41及該第二自潤軸套42內部易受磨損而需要使用耐磨材質，該踏板本體2則可以使用重量較輕且成本較低的塑膠或其他材質，可大幅減輕重量及降低原料成本，且當使用時間較久而產生磨損時，也只需要替換該第一自潤軸套41及該第二自潤軸套42即可，進而降低維護上的成本。2. The mandrel 3 is in contact with the first self-lubricating sleeve 41 and the second self-lubricating sleeve 42 , and the first self-lubricating sleeve 41 and the second self-lubricating sleeve 42 are fitted thereto. The first engaging portion 204 and the second engaging portion 206 do not interlock with the rotation of the spindle 3, so only the first self-lubricating sleeve 41 and the second self-lubricating sleeve 42 are susceptible to wear and need to use wear-resistant materials. The pedal body 2 can use lighter weight and lower cost plastic or other materials, which can greatly reduce weight and reduce raw material cost. Moreover, when the wear time is long and wear occurs, only the first self-lubricating bushing 41 and the second self-lubricating bushing 42 need to be replaced, thereby reducing the maintenance cost.
三、藉由在該心軸3的限位端32沖壓出該限位凸緣321，可將該踏板本體2、該心軸3與該自潤軸套單元4進行完善固定，而藉由將該限位凸緣321設計為均勻對稱的形狀，可使心軸3在轉動時，能夠藉由該限位凸緣321而得到均勻完整的支撐力，避免該限位凸緣321因形狀不對稱導致受力不均而破裂時，會影響該心軸3轉動的順暢度。3. By punching the limiting flange 321 at the limiting end 32 of the mandrel 3, the pedal body 2, the mandrel 3 and the self-lubricating sleeve unit 4 can be perfectly fixed, and The limiting flange 321 is designed to have a uniform symmetrical shape, so that when the mandrel 3 is rotated, a uniform and complete supporting force can be obtained by the limiting flange 321 to prevent the limiting flange 321 from being asymmetrical in shape. When the force is uneven and the rupture occurs, the smoothness of the rotation of the mandrel 3 is affected.
參閱圖7及圖8，為本新型自行車踏板的一第二較佳實施例，該第二較佳實施例是類似於該第一較佳實施例，該第二較佳實施例與該第一較佳實施例的差異在於：該第一卡合部204及該第二卡合部206分別設置於該等大孔徑區21，且該第一卡合部204及該第二卡合部206之內壁截面為正六邊形，該第一自潤軸套41及該第二自潤軸套42的外環面為對應的正六邊形以分別形成該等卡合部411、421。Referring to FIG. 7 and FIG. 8 , a second preferred embodiment of the bicycle pedal of the present invention is similar to the first preferred embodiment, the second preferred embodiment and the first The difference between the preferred embodiment is that the first engaging portion 204 and the second engaging portion 206 are respectively disposed in the large aperture regions 21, and the first engaging portion 204 and the second engaging portion 206 are The inner wall has a regular hexagonal cross section, and the outer surface of the first self-lubricating sleeve 41 and the second self-lubricating sleeve 42 has a corresponding regular hexagon to form the engaging portions 411 and 421, respectively.
於本實施例中，該第一卡合部204、該第二卡合部206之內壁截面與該第一自潤軸套41及該第二自潤軸套42的卡合部411、421為正六邊形，但亦可為能相互嵌合的任意非圓形的形狀，並不限於此。In the embodiment, the inner wall of the first engaging portion 204 and the second engaging portion 206 and the engaging portions 411 and 421 of the first self-lubricating sleeve 41 and the second self-lubricating sleeve 42 are respectively included. It is a regular hexagon, but it may be any non-circular shape that can be fitted to each other, and is not limited thereto.
如此，該第二較佳實施例亦可達到與上述第一較佳實施例相同的目的與功效。Thus, the second preferred embodiment can achieve the same purpose and effect as the first preferred embodiment described above.
綜上所述，本新型不僅可減少元件的複雜度，減輕重量，還可降低製造上及維護上的成本，故確實能達成本新型之目的。In summary, the novel can not only reduce the complexity of components, reduce weight, but also reduce the cost of manufacturing and maintenance, so it can achieve the purpose of the present invention.
惟以上所述者，僅為本新型之較佳實施例而已，當不能以此限定本新型實施之範圍，即大凡依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本新型專利涵蓋之範圍內。However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
