Description of the Invention: [Technical Field] The present invention relates to a universal joint structure, and more particularly to a universal joint structure which can reduce material cost and manufacture labor without losing structural strength. [Prior Art] According to the 'universal connection seat, it can be used for connecting the mats of machines or equipment (such as treadmills, sports equipment, tables, etc.), or the connection of the moving arm of the machine. It is very versatile, and the main function is to make the connection The object to the connector can be adjusted at an angle of 36 () degrees. In terms of the structure of the connecting seat of the conventional connecting foot pad, the following types are available: 1. As shown in the first and second figures, the connecting seat 10 does not have a universal function, that is, the angle of the connecting seat cannot be adjusted, A plastic base 11 is coupled to an upwardly extending bolt 12 above the base 11. In use, the top end of the bolt 12 is coupled to the bottom end of the machine or apparatus. This connector 10 does not have an angle adjustment function.
2·第三、四圖所示之連接座2〇具有角度調整之萬向功能，具 一底座21 ’底座21為一實心金屬材質所製成，頂端以鍛 造再經車床加工方式成型一幾為半圓狀之嵌珠孔210 ;具 一螺栓22 ’底端固定一珠球220嵌入底座21之喪珠孔210 内，並受嵌珠孔210頸部束住，使珠球不會脫離嵌珠孔 210 ’但可於喪珠孔210内作角度調整位移；具一塑性套 23 ’係嵌固在底座21底端，俾提升底座21之止滑性。該 款連接座20之螺栓22雖可作角度調整之萬向功能且結構 性佳，但底座21係由實心金屬材質製成，且嵌珠孔21〇以 1290609 锻k再經車床加工方式成型’不僅材料成本高，製造上亦 費工、耗時，以致製造成本高。2·The connecting seat 2〇 shown in the third and fourth figures has the universal function of angle adjustment, and has a base 21'. The base 21 is made of a solid metal material, and the top end is forged and then formed by lathe processing. Semi-circular bead hole 210; with a bolt 22' fixed at the bottom end, a bead ball 220 is embedded in the bead hole 210 of the base 21, and is bundled by the neck of the bead hole 210 so that the bead ball does not escape from the bead hole. 210 'but the angle can be adjusted in the bead hole 210; a plastic sleeve 23 ' is embedded in the bottom end of the base 21 to lift the slip resistance of the base 21. Although the bolt 22 of the connecting seat 20 can be used for the universal function of angle adjustment and the structure is good, the base 21 is made of solid metal material, and the bead hole 21 is forged by 1290609 and then formed by lathe processing. Not only is the material cost high, but it is also labor intensive and time consuming to manufacture, resulting in high manufacturing costs.
3·如第五、六圖所示之r連接座3〇，具一底座31，係由塑料所 成型，頂端成型一幾為半圓狀之嵌珠孔310 ;具一螺栓32， 底端具一珠球320可強力嵌入嵌珠孔310内，俾珠球32〇 被限位在嵌珠孔310内，且能於嵌珠孔310内滑動，使螺 栓32可作角度調整。惟，該款連接座30之底座31由塑性 材質製成，結構剛性差，不耐較重負荷。 本發明人有鑑於習知連接座在製造或使用上分別具有上列缺 失，乃加以設計改良，遂有本發明之產生。 【發明内容】 緣是，本發明之主要發明目的係在提供一種結構剛性佳，且 可降低製造及材料成本之萬向連接座結構。 本發明之主要特徵係在：底座係由一金屬板成型且呈皿狀之 外座，及一亦由金屬板所製造嵌固在外座皿口内之内襯板所組 、成。外座中間具-圓形嵌人口，喪人口之口緣往内襯板背向突伸 有夾口緣；内襯板中間對應外座嵌入口處往背向外座端凹設一弧 形槽，俾弧形槽與喪入π、夾口緣間區隔形成一嵌珠孔。藉底座 如此設置，俾連接件(螺栓)之珠球嵌入嵌珠孔内，珠球可被夾口緣 夾束，使珠球被限位在嵌珠孔内，而連接件可作角度調整之萬向 功能。 【實施方式】 有關本發明為達成上述目的、功效所採用之技術手段及結 1290609 構，茲舉二較佳可行實施例並配合圖式詳細說明如下，俾使審查 委員更易於瞭解本發明之產生。 請參閱第七、八圖所示，本實施例係供作腳墊連接用，連接 座40之底座41具有： 一外座410，係由金屬板所製成，呈皿狀設計，中間具一圓形 後入口 4101，喪入口 4101 口緣向外突伸有一夹口緣4102。3. The r-connector 3〇 shown in the fifth and sixth figures has a base 31 which is formed of plastic and has a semi-circular bead hole 310 formed at the top end; a bolt 32 and a bottom end having a The bead ball 320 can be strongly embedded in the bead hole 310, and the bead ball 32 is restrained in the bead hole 310, and can slide in the bead hole 310, so that the bolt 32 can be adjusted in angle. However, the base 31 of the connector 30 is made of a plastic material and has a poor rigidity and is not resistant to heavy loads. The present inventors have made improvements in design in view of the fact that the conventional connector has the above-mentioned missing defects in manufacturing or use, and the present invention has been produced. SUMMARY OF THE INVENTION It is a primary object of the present invention to provide a universal joint structure which is excellent in structural rigidity and which can reduce manufacturing and material costs. The main feature of the present invention is that the base is formed by a metal plate and is in the form of a dish, and an inner liner which is also made of a metal plate and is embedded in the outer mouth of the outer plate. The outer seat has a round-shaped embedded body, and the edge of the mourning population protrudes toward the inner lining plate with a spigot edge; the middle lining plate corresponds to the outer seat insertion opening, and a curved groove is recessed toward the back and the outer seat end. The arc-shaped groove is separated from the π and the edge of the nip to form a bead hole. By means of the base, the bead of the connecting piece (bolt) is embedded in the bead hole, and the bead ball can be clamped by the clamping edge, so that the bead ball is restrained in the bead hole, and the connecting piece can be adjusted by the angle. Universal function. [Embodiment] The technical means and the structure of the present invention for achieving the above object and effect are as follows, and the following is a detailed description of the preferred embodiment and the following description, so that the reviewing committee can more easily understand the generation of the present invention. . Referring to the seventh and eighth figures, the embodiment is used for the connection of the foot pad. The base 41 of the connecting base 40 has: an outer seat 410, which is made of a metal plate and has a dish shape and a middle portion. A circular rear inlet 4101, a rim edge 4102 protrudes outward from the rim of the entrance 4101.
一内襯板411，亦由金屬板所製成，係嵌入外座41〇之皿口内， 亦為皿狀設計，内襯板411之外牆4110較外座410外牆4103短， 俾外座410之外牆4103底端向内折彎時，可將内襯板411之外牆 4110底端頂住，使二者固結一體。内襯板4Π之頂面中間配合外 座410之嵌入口 4101位置處往背向外座410端凹設一弧形槽 4111，俾弧形槽4111與嵌入口 4101、夹口緣4102三者區隔形成 一嵌珠孔412(如第八圖所示），以供一連接件42(或螺栓)端部所固 接之珠球420嵌入。 於底座41之底端可穿套一具止滑及塑性之塑性套幻，以幫助 ^底座41之止滑性。 s將上述構件組合後，即如第八圖所示，使用時，即如第九 圖所示般，連接件42可藉珠球420於嵌珠孔412内滑動而作角度 調整之萬向效果。 接著請參閱第十圖所示，底座41之外座與内襯板411間 之固定，可於相貼處A以焊接方式固定。 本發明之萬向連接絲可供機H、設備等之·連接用外， 亦可如第十-騎示，朗於手臂需作多角度位移之使用。應用 1290609 時不需設置塑性套43，而將底座41與一固定面B固定，連接件 42位置可被手臂替代使用。 由上列之說明可知，本發明萬向連接座之底座41由金屬板所 製成之外座410及内襯板411所固接而成，並以沖壓方式成型嵌 珠孔412，在材料成本上不僅可降低、製造上亦較省工，結構剛性 又佳，確可改善習知缺失具產業利用性及進步性。An inner liner 411 is also made of a metal plate and is embedded in the mouth of the outer seat 41. The inner wall 4110 of the inner liner 411 is shorter than the outer wall 4103 of the outer seat 410. When the bottom end of the outer wall 4103 is bent inward, the bottom end of the outer wall 4110 of the inner liner 411 can be supported to make the two integrally consolidated. The top surface of the inner liner 4 is fitted with an arcuate groove 4111 at the end of the inserting port 4101 of the outer seat 410, and the arcuate groove 4111 is formed with the arcuate groove 4111 and the inserting opening 4101 and the clamping edge 4102. A bead hole 412 (shown in FIG. 8) is formed to be embedded in the bead 420 to which the end of a connecting member 42 (or bolt) is fixed. At the bottom end of the base 41, a slip-like and plastic plastic sleeve can be worn to help the slip resistance of the base 41. After the above components are combined, as shown in the eighth figure, when used, that is, as shown in the ninth figure, the connecting member 42 can slide the bead ball 420 in the bead hole 412 to make an angular adjustment effect. . Next, as shown in the tenth figure, the fixing between the outer seat of the base 41 and the inner liner 411 can be fixed by welding at the abutting portion A. The universal joint wire of the present invention can be used for the connection of the machine H, the equipment, etc., and can also be used as a tenth-riding, and the arm needs to be used for multi-angle displacement. When the 1290609 is applied, the plastic sleeve 43 is not required, and the base 41 is fixed to a fixing surface B, and the position of the connecting member 42 can be replaced by the arm. It can be seen from the above description that the base 41 of the universal joint of the present invention is made of a metal plate and the outer seat 410 and the inner liner 411 are fixed, and the bead hole 412 is formed by punching, at the material cost. Not only can it be reduced, it is also more labor-saving, and the structural rigidity is good. It can improve the industrial use and progress of the lack of knowledge.
