Description

活动扳手 adjustable wrench

技术领域 technical field

本发明涉及一种可轻易调整夹口间距的活动扳手领域。The invention relates to the field of an adjustable wrench which can easily adjust the distance between jaws.

背景技术 Background technique

据本人所知,一般制造机械到建筑工程中所使用的工具当中,其中可转动螺固件的手工具,以可调整夹口尺寸的活动扳手最为方便,然而一般活动扳手的夹口尺寸调整,必须转动设置于靠近头部的蜗杆,才能带动活动颚移动,而慢慢地调整其夹口尺寸,很明显效率不佳,并且该蜗杆与齿部之间有空隙,将会使活动颚产生晃动,进而改变两夹口的尺寸,一来有无法方便的再次连续使用的缺点,二来又有容易松脱、滑出螺固件(Fasteners)的危险。As far as I know, among the tools used in general manufacturing machinery and construction engineering, among the hand tools that can rotate screw parts, the adjustable wrench with adjustable jaw size is the most convenient. However, the jaw size adjustment of general adjustable wrench must be adjusted. Only by turning the worm screw installed close to the head can the movable jaw move, but slowly adjusting the jaw size is obviously inefficient, and there is a gap between the worm and the teeth, which will cause the movable jaw to shake. Furthermore, changing the size of the two jaws has the disadvantage that it cannot be used continuously again conveniently, and there is also the danger of easy loosening and slipping out of the fasteners (Fasteners).

为克服此问题,如美国专利案第US1523093号所示,该案例中是将板手头部内设一容置孔,可供两齿块置入,两齿块的齿面为一交错状,并且可使其中一齿块来啮合活动颚齿条,而另一齿块则呈脱离状态,且拨动操作部时,可使两齿块与齿条分离,即可调整活动颚与固定颚的尺寸。因为只是在活动颚的圆杆的底缘,设单一齿条,因此仅能使用于单一尺寸(公制单位或英制单位)的齿距调整,此在公、英制并存的国家(如美国),将造成使用者须同时购买公制单位(Metric)、及英制单位(SAE)各一支,不但造成浪费,且一般使用者,也分不清该螺固件是公制单位(Metric)或是英制单位(SAE),容易因使用者的混淆,造成操作上的错误(如扳手啮合后的两夹口尺寸,与螺固件对边尺寸,会有较大的间隙),而使螺固件螺角受损或发生滑脱意外情况;且该活动颚圆杆的底缘,仅设单一齿条,其齿面宽度本就狭窄,要能同时容纳两齿块,其中一齿啮合的齿面宽度只有一半,将有崩裂的危险。To overcome this problem, as shown in U.S. Patent No. US1523093, in this case, an accommodating hole is provided in the head of the wrench for the insertion of two tooth blocks. The tooth surfaces of the two tooth blocks are in a staggered shape. And one of the tooth blocks can be engaged with the rack of the movable jaw, while the other tooth block is in a disengaged state, and when the operating part is moved, the two tooth blocks can be separated from the rack, and the relationship between the movable jaw and the fixed jaw can be adjusted. size. Because there is only a single rack on the bottom edge of the round bar of the movable jaw, it can only be used for tooth pitch adjustment of a single size (metric or imperial). In countries where metric and imperial systems coexist (such as the United States), it will This causes the user to purchase one metric unit (Metric) and one imperial unit (SAE) at the same time, which not only causes waste, but also makes it difficult for ordinary users to distinguish whether the screw is in metric units (Metric) or imperial units (SAE). ), it is easy to cause operational errors due to user confusion (such as the size of the two jaws after the wrench is engaged, and the size of the opposite side of the screw, there will be a large gap), which will damage the helix of the screw or cause In case of accidental slippage; and the bottom edge of the movable jaw rod is only equipped with a single rack, and the width of the tooth surface is narrow. If it can accommodate two tooth blocks at the same time, the width of the tooth surface of one tooth meshing is only half, and there will be cracks. danger.

有鉴于此,提供一种解决上述问题的扳手,本发明提供如下文详细说明中所述具创新性的活动扳手。In view of this, a wrench to solve the above problems is provided, and the present invention provides an innovative adjustable wrench as described in the following detailed description.

本发明有关一种活动扳手,有关本发明为达上述目的、特征所采用技术手段及其功效,请先参照图1至图4所示,以其对应下列的叙述:The present invention relates to an adjustable wrench. Regarding the technical means and effects of the present invention to achieve the above-mentioned purpose and features, please refer to Fig. 1 to Fig. 4 for the following descriptions:

本发明主要包括一本体1及一活动颚20,其中该本体1具有一柄部10及一头部11,该头部11延伸有一固定颚12,该固定颚12一侧并形成有一固定颚夹部16,头部11纵向则设有一滑槽14,头部11沿厚度的横向设有与滑槽14相连通的长形容置孔15,该滑槽远离固定颚12端的头部11表面则贯设一孔13,可供一销50插设;The present invention mainly includes a body 1 and a movable jaw 20, wherein the body 1 has a handle 10 and a head 11, the head 11 extends a fixed jaw 12, and a fixed jaw is formed on one side of the fixed jaw 12 16, the head 11 is provided with a chute 14 longitudinally, and the head 11 is provided with a long accommodating hole 15 communicating with the chute 14 along the transverse direction of the thickness, and the surface of the head 11 which is far from the end of the fixed jaw 12 runs through the chute. A hole 13 is provided for insertion of a pin 50;

一活动颚20,具有一导引部21及一活动颚夹部22,该导引部21是对应滑槽14形态设计且可容设于滑槽14内,令活动颚20可透过导引部21沿着滑槽14移动,而活动颚夹部22则与固定颚形成一夹部空间,供夹持螺固件,另导引部21与活动颚夹部22的连接处,形成一凹槽23,该凹槽23可使活动颚20朝外位移时可与销50相抵靠,并防止活动颚掉落,而该导引部21底缘的两侧设有左、右的两排齿部24,该两排齿部24的齿距可如图2所示,呈现不同的齿距(可分别为公制单位齿距与英制单位齿距),另该两排齿部24的形状,也可如图3所示,可概呈一凹弧状、一斜面状或一凸弧状,如此可令齿部24的面积增加,扩大与下述啮合件30的接触面积;A movable jaw 20 has a guide part 21 and a movable jaw clamp part 22, the guide part 21 is designed corresponding to the shape of the chute 14 and can be accommodated in the chute 14, so that the movable jaw 20 can pass through the guide The part 21 moves along the chute 14, while the movable jaw part 22 and the fixed jaw form a clip part space for clamping the screw, and the connection between the guide part 21 and the movable jaw part 22 forms a groove 23. The groove 23 can make the movable jaw 20 abut against the pin 50 when it moves outwards, and prevent the movable jaw from falling, and the two sides of the bottom edge of the guide part 21 are provided with two rows of teeth on the left and right 24. The pitches of the two rows of teeth 24 can be shown in Figure 2, showing different pitches (respectively metric unit pitches and imperial unit pitches), and the shape of the two rows of teeth 24 can also be As shown in FIG. 3 , it can be in a concave arc shape, an inclined plane shape or a convex arc shape, so that the area of the tooth portion 24 can be increased, and the contact area with the following engaging member 30 can be expanded;

一啮合件30,具有左、右的两齿块31,该齿块31对应容置孔15的长形块体,以可朝向接近或远离该活动颚20方向移动方式设置在头部11的容置孔15,该两齿块31靠近活动颚20端设有齿面32,远离活动颚底端的两侧则设有底孔34供一弹性件35容设,并藉由弹性件35底端与容置孔15底面抵靠而得迫使齿块31的齿面32与活动颚20的齿部24相互啮合,因此该齿面32的形状尺寸是与活动颚20的齿部相对应的,另外,两齿块31沿厚度方向则贯设一呈垂直状的椭圆孔33,供拨动件穿结之用;An engaging piece 30 has two left and right tooth blocks 31, the tooth blocks 31 correspond to the elongated blocks of the housing hole 15, and are arranged in the housing of the head 11 in a manner that can move toward or away from the movable jaw 20. Set hole 15, these two tooth blocks 31 are provided with tooth surface 32 near movable jaw 20 end, then are provided with bottom hole 34 for an elastic member 35 to accommodate at both sides away from movable jaw bottom end, and by elastic member 35 bottom end and The bottom surface of the accommodating hole 15 abuts to force the tooth surface 32 of the tooth block 31 to mesh with the tooth portion 24 of the movable jaw 20, so the shape and size of the tooth surface 32 correspond to the tooth portion of the movable jaw 20. In addition, A vertical elliptical hole 33 is formed through the two tooth blocks 31 along the thickness direction, which is used for threading and knotting of the toggle piece;

一拨动件40,具有两操作部41及一连接件42,该两操作部41是设于头部11容置孔15的两侧,且该操作部41设有一圆孔411,并利用连接件42连接穿设圆孔411及齿块31的椭圆孔33,使连接件42连接于操作部41与啮合件30,让拨动件40可控制啮合件30接近或远离活动颚20的齿部24,其中该操作部41外侧底部形成一凸缘412,供使用者方便施力拨动。A toggle member 40 has two operating parts 41 and a connecting part 42, the two operating parts 41 are located on both sides of the accommodation hole 15 of the head 11, and the operating part 41 is provided with a round hole 411, and is connected by connecting The piece 42 is connected to the oval hole 33 through the round hole 411 and the gear block 31, so that the connecting piece 42 is connected to the operation part 41 and the engaging piece 30, so that the toggle piece 40 can control the engaging piece 30 to approach or stay away from the teeth of the movable jaw 20 24, wherein a flange 412 is formed on the outer bottom of the operation part 41 for the user to conveniently apply force to move it.

本发明的使用动作请参阅图5、图6所示,由于设置于容置孔15内的啮合件30,是藉由弹性件35推抵使齿面32与齿部24可相互啮合,此时将设于头部11的操作部41往凸缘412方向推动时,可藉由连接件42使啮合件30远离活动颚的齿部,如此可令导引部21的两排齿部24与啮合件30的齿面32分离,即可使导引部21于滑槽14左右滑动,而能够调整活动颚20与固定颚12的夹持开口尺寸;另外,如图7、图8所示,当放开操作部41,并推抵活动颚的导引部21,向固定颚12的方向移动时,因两排齿部24的齿面,与相对应的啮合件30的齿面32,皆呈锯齿状,所以啮合件30会受到导引部21推抵的垂直分力而向下,而与两排齿部24的齿面暂时呈脱离状态,致使活动颚的导引部21能朝向固定颚12的方向移动;而当停止推抵活动颚的导引部21时,则啮合件30的齿块受弹性件的推抵,其中一齿块31的齿面32,可自动会与相对应的活动颚20的一齿部24互相完全啮合,即可固定该活动颚20;Please refer to Fig. 5 and Fig. 6 for the operation of the present invention. Since the engaging member 30 arranged in the accommodating hole 15 is pushed against by the elastic member 35, the tooth surface 32 and the tooth portion 24 can mesh with each other. When the operating part 41 provided on the head 11 is pushed toward the flange 412, the engaging part 30 can be kept away from the teeth of the movable jaw through the connecting part 42, so that the two rows of teeth 24 of the guide part 21 can be engaged with The tooth surface 32 of the piece 30 is separated, so that the guide part 21 can slide left and right in the chute 14, and the size of the clamping opening between the movable jaw 20 and the fixed jaw 12 can be adjusted; in addition, as shown in Figure 7 and Figure 8, when When the operating part 41 is released and pushed against the guide part 21 of the movable jaw, and moves toward the direction of the fixed jaw 12, the tooth surfaces of the two rows of tooth parts 24 and the tooth surfaces 32 of the corresponding meshing parts 30 are in the same shape. Serrated, so the engaging part 30 will be pushed downward by the vertical component force pushed by the guide part 21, and temporarily disengages from the tooth surfaces of the two rows of teeth parts 24, so that the guide part 21 of the movable jaw can face the fixed jaw 12; and when the push against the guide part 21 of the movable jaw is stopped, the tooth block of the meshing piece 30 is pushed by the elastic piece, and the tooth surface 32 of one of the tooth blocks 31 can automatically meet the corresponding A tooth portion 24 of the movable jaw 20 is completely meshed with each other, so that the movable jaw 20 can be fixed;

另外请参阅图9所示,若欲夹合螺固件时,仅需推抵活动颚20的导引部21的一端面,也可以在活动颚20的适当位置设有一推抵部25,推抵部25可为凹弧状(如图9),或传统活动颚的几何图形(如图1)、或有止滑结构,以增加使用者推抵的摩擦力,因活动颚的两排齿部24的齿型与齿块31的齿面32皆为一锯齿型状,所以可迫使活动颚20仅能朝向固定颚12方向内缩位移,当推抵活动颚20内缩位移时,即如图10所示,活动颚20的左排齿部24(为英制单位齿距),与左齿块31的齿面32(为英制单位齿距)则自动互相啮合,此时活动颚20的右排齿部24(为公制单位齿距)则与右齿块31的齿面32(为公制单位齿距)相分离,当再次推抵活动颚20内缩位移一微小距离时,则如图11所示,活动颚20的右排齿部24(为公制单位齿距)则与右齿块31的齿面32(为公制单位齿距)自动互相啮合,而活动颚20的左排齿部24(为英制单位齿距),与左齿块31的齿面32(为英制单位齿距)则相分离;利用此结构,即可使该活动扳手同时适用扳动于英制单位螺固件与公制单位的螺固件,让使用者不需要去注意螺固件是英制、或公制单位,只要向内推抵活动颚20,使其位移、靠近至螺固件的对边面即可;Please also refer to Figure 9, if you want to clamp the screw, you only need to push against one end surface of the guide part 21 of the movable jaw 20, and a push part 25 can also be provided at an appropriate position of the movable jaw 20 to push against it. The part 25 can be concave arc-shaped (as shown in Figure 9), or the geometric figure of the traditional movable jaw (as shown in Figure 1), or have a non-slip structure to increase the friction force pushed by the user, because the two rows of teeth 24 of the movable jaw The tooth shape and the tooth surface 32 of the tooth block 31 are both in a sawtooth shape, so the movable jaw 20 can only be forced to retract inwardly in the direction of the fixed jaw 12. When pushing against the retractable displacement of the movable jaw 20, as shown in Figure 10 As shown, the left row of teeth 24 of the movable jaw 20 (for the imperial unit pitch) and the tooth surface 32 of the left tooth block 31 (for the imperial unit pitch) are automatically meshed with each other. At this time, the right row of teeth of the movable jaw 20 The part 24 (for the metric unit pitch) is separated from the tooth surface 32 (for the metric unit pitch) of the right tooth block 31, and when the movable jaw 20 is pushed against the movable jaw 20 and retracted for a small distance, as shown in Figure 11 , the right row of teeth 24 (for the metric unit pitch) of the movable jaw 20 automatically meshes with the tooth surface 32 (for the metric unit pitch) of the right tooth block 31, and the left row of teeth 24 (for the metric unit pitch) of the movable jaw 20 Inch unit tooth pitch) is separated from the tooth surface 32 of the left tooth block 31 (in imperial unit tooth pitch); with this structure, the adjustable wrench can be used to wrench the imperial unit screw and the metric unit screw at the same time. Firmware, so that the user does not need to pay attention to whether the screw is in imperial or metric units, as long as the movable jaw 20 is pushed inward to make it displace and close to the opposite side of the screw;

另外也可以将活动颚20的左右排齿部24设为相同间距的齿距(公制单位mm或英制单位in),左右排齿部24是间隔、交错设置而成,举例若两齿块皆为公制单位,且又相同齿距时,每一齿距设为1mm,如左右排齿部24相互间隔、交错设置,当推抵活动颚20内缩位移时,则会形成为左齿块31与左齿部24相啮合,而此时右齿块31则与右排齿部24相分离,再继续推抵时,则会形成左齿块31与左排齿部24相分离,而此时右齿块31则与右排齿部24相啮合,如成可使左右排齿部24轮流为一啮合-分离-啮合-分离的动作,即可使活动颚内缩位移的每一间距,缩小为0.5mm,如此可令活动颚20与固定颚12夹合螺固件时产生的间距减少,更可紧密贴合螺固件,有效减少螺固件螺角受损的情形。In addition, the left and right rows of teeth 24 of the movable jaw 20 can also be set to the same pitch (metric unit mm or imperial unit in), and the left and right rows of teeth 24 are arranged at intervals and staggered. For example, if both tooth blocks are Metric units, and when the tooth pitch is the same, each tooth pitch is set to 1mm. If the left and right rows of teeth 24 are spaced apart from each other and arranged in a staggered manner, when the movable jaw 20 is pushed and retracted, the left tooth block 31 and the left tooth block 31 will be formed. The left tooth part 24 is meshed, and at this time the right tooth block 31 is separated from the right row of tooth part 24. The tooth block 31 is meshed with the right row of teeth 24. If it is completed, the left and right rows of teeth 24 can be engaged-separated-engaged-separated in turn, so that each distance of the retractable displacement of the movable jaw can be reduced to 0.5 mm, so that the distance between the movable jaw 20 and the fixed jaw 12 can be reduced when the screw is clamped, and the screw can be closely attached to the screw, effectively reducing the damage to the thread angle of the screw.

综合上述,本发明可达以下特点:Based on the above, the present invention can achieve the following characteristics:

一、本发明利用活动颚导引部底缘设有两排齿部,该两排齿部可为不同间距的齿距,一排为公制单位齿部,另一排为英制单位齿部,如此配合相对应的啮合件,即可使该活动扳手同时应用扳动于公制单位螺固件与英制单位螺固件。1. In the present invention, two rows of teeth are provided on the bottom edge of the guide part of the movable jaw. The two rows of teeth can have different pitches. One row is the teeth of metric units, and the other row is the teeth of imperial units. Cooperating with the corresponding engaging parts, the adjustable wrench can be used to wrench the metric unit screw and the imperial unit screw at the same time.

二、本发明利用活动颚导引部底缘设有两排齿部,该两排齿部可为相同间距的齿距,且相间隔、交错设置,如此配合相对应的啮合件,既可以使该活动扳手的固定颚与活动颚夹合螺固件时产生的间距减少,又可以紧密贴合螺固件,有效减少螺固件螺角受损的情形。2. In the present invention, two rows of teeth are provided on the bottom edge of the guide part of the movable jaw. The two rows of teeth can have the same tooth pitch, and they are spaced apart and arranged in a staggered manner. In this way, the corresponding meshing parts can be used.
