Description
本發明係與扭力扳手結構有關，尤指一種扭力扳手設有第一指標，該第一指標係隨調整組位移而位移而知其扭力值。The invention relates to the structure of a torque wrench, in particular to a torque wrench which is provided with a first index, and the first index is displaced according to the displacement of the adjustment group to know the torque value.
按吾人先前所知，習用之扭力扳手結構，如美國專利號第US7703357B1，同台灣專利第098204659，該專利名稱：扭力設定扳手之旋柄結構，其係包括：一種扭力設定扳手之旋柄結構，該扭力設定扳手係包括有一具作用插接端之棘輪驅動部、一施力柄、一扭力調整桿、一可被原位旋動之旋柄及一扭力設定指針；其特徵在於：其主要係於施力柄近末端處，配合一鎖固件而先行鎖固有一中空套環，並於該套環級式內孔相鄰於旋柄之一側，又設有一內環齒，俾配合具對應外環齒之旋柄及一彈性體之作用，使套環及旋柄之內、外環齒成常態之囓合卡止狀態；因此，當欲調整扭力值時，僅須將旋柄向套環方向壓掣使內、外環齒脫離，便得以旋動旋柄以帶動扭力值設定機構之扭力調整桿，達成預期之調整效用，待調整完成，則僅須解除外力並藉彈性體之自身彈力，自動使內、外環齒歸復常態之囓合卡止狀態者，此係該專利之設計結構。As is known in the prior art, the conventional torque wrench structure, such as U.S. Patent No. 7,703,357 B1, and Taiwan Patent No. 098,204,659, the patent name: Torque setting wrench knob structure, which includes: a torque setting wrench handle structure, The torque setting wrench comprises a ratchet driving part with a working insertion end, a force applying handle, a torque adjusting rod, a knob which can be rotated in the ground and a torque setting pointer; the main feature is: At the near end of the urging handle, a hollow collar is locked firstly with a locking fastener, and the inner hole of the ring-shaped inner hole is adjacent to one side of the shank, and an inner ring tooth is provided, and the outer ring of the cymbal is matched. The action of the tooth knob and an elastic body causes the inner and outer ring teeth of the collar and the knob to be in a normal engagement state; therefore, when the torque value is to be adjusted, the knob only needs to be pressed toward the collar.掣The inner and outer ring teeth are disengaged, and the knob can be rotated to drive the torque adjustment rod of the torque value setting mechanism to achieve the desired adjustment effect. After the adjustment is completed, only the external force must be released and the elastic force of the elastic body is automatically Inner and outer rings of teeth return multiplexed normal state by engagement of the locking design of the system structure of this patent.
但該專利之結構缺失係在於：當旋動旋柄(25)而帶動扭力調整桿(24)旋轉時，該扭力設定指針(26)係連同位移之，繼而配合位於旁側之刻度表(33)以判讀扭力設定值，但該扭力設定指針(26)與刻度表(33)間係為小刻度對照之判讀，且讀取方方式係要人自已去判斷二者間之相對位置，當使用者操作於光線昏暗之工作環境，或使用者本身視力不佳，該種指針與刻度判讀扭力數值大小之方式係有改善空間。However, the structural deletion of the patent is that when the rotary handle (25) is rotated to drive the torsion adjustment lever (24) to rotate, the torque setting pointer (26) is coupled with the displacement, and then cooperates with the scale on the side (33). ) to determine the torque setting value, but the torque setting pointer (26) and the scale table (33) are interpreted as small scales, and the reading method is the person to judge the relative position between the two, when used The operation is in a dimly lit working environment, or the user's own vision is poor, and there is room for improvement in the manner in which the pointer and the scale determine the magnitude of the torque.
又如另一專利案之扭力扳手結構，如美國專利號第US7685889B2，同台灣專利號第097102779，該專利名稱：數位扭力量測工具，一種數位扭力量測工具，其係包括一本體，該本體係設有一驅動部、一身部、及一握持部，其中：該驅動部係設有一驅動頭，該本體係藉由驅動頭之作動達到預期作業功效；該握持部係設為適當之長度，以供使用者握持之用；該身部係設有一容置單元，該容置單元係供一電子機構容置之用，該電子機構內係設有至少一容置空間，該容置空間內係設有至少二層電路單元，該電路單元係利用層疊方式裝設；俾利，藉由該電子機構之電路單元層疊結構縮小體積，達到有效率利用容置單元之功效，且該電子機構亦利用電路單元之層疊結構，增加所能裝設之電路單元，以達到多功能之效果者。A torque wrench structure of another patent, such as U.S. Patent No. 7,685,889 B2, and Taiwan Patent No. 097102779, the patent name: digital torsion force measuring tool, a digital torsion force measuring tool, comprising a body, the body The system is provided with a driving part, a body part and a holding part, wherein: the driving part is provided with a driving head, and the system achieves the expected working effect by the driving head; the holding part is set to an appropriate length For the user to hold; the body is provided with a accommodating unit for accommodating an electronic device, and the electronic device is provided with at least one accommodating space, the accommodating The space is provided with at least two layers of circuit units, and the circuit unit is installed by using a stacking method; by means of the circuit unit laminated structure of the electronic mechanism, the volume is reduced to achieve efficient use of the accommodating unit, and the electronic device The mechanism also utilizes the laminated structure of the circuit unit to increase the circuit unit that can be installed to achieve the multi-functional effect.
此專利案結構優點係在於可改善上述習用美國專利第US7703357B1由自已讀取數值之缺失，該電子機構(5)係可提供明確之扳手扭力數值大小，一般而言該電子機構(5)內係設有電路板，電路板係可顯示出具有數字之數位數值而較便於使用者讀取，且電子機構(5)所顯示出扭力數值之螢幕係具光源而令使用者更明確了解。The structural advantage of this patent is that it can improve the above-mentioned conventional US Patent No. 7,703,357 B1, which lacks the value of the self-reading value. The electronic mechanism (5) can provide a clear value of the wrench torque. Generally, the electronic mechanism (5) is internal. A circuit board is provided, and the circuit board can display a light source with a numerical value of a digital value and is more convenient for the user to read, and the electronic mechanism (5) displays the torque value to make the user understand more clearly.
但該專利結構缺失係在於：該電子機構(5)需有電池作為整體之電能以顯示具有數字之扭力數值，而當電子機構(5)內之電能耗盡，且工作環境係無法立即補充電能或電池的情況下，如外出修理各機械或外出修車時，電子機構(5)即會因無電池狀態下即無法再顯示扭力值，扭力扳手結構僅能當一般扳手作使用而不具測量扭力值之功效。However, the patent structure is missing: the electronic mechanism (5) needs to have a battery as a whole electric energy to display a numerical torque value, and when the electric energy in the electronic mechanism (5) is exhausted, and the working environment cannot immediately replenish electric energy. In the case of a battery, if the machine is repaired or repaired, the electronic mechanism (5) will not be able to display the torque value even if the battery is not in use. The torque wrench structure can only be used as a normal wrench without measuring the torque. The value of the value.
有鑑於上述各專利案結構，本發明人藉多年從事相關行業之經驗，終於有一能解決習用弊端之扭力扳手結構之產品問世。In view of the structure of the above patents, the inventors have borrowed years of experience in related industries, and finally have a product that can solve the drawbacks of the torque wrench structure.
一種扭力扳手結構設有第一指標，該第一指標係隨調整組位移而位移，顯示機構即知其扭力值。A torque wrench structure is provided with a first index, the first index is displaced with the displacement of the adjustment group, and the display mechanism knows the torque value.

本發明扭力扳手結構之優點係在於：The advantages of the torque wrench structure of the present invention are:
1、本發明主要原理在於：該調整塊(53)位移時係會控制彈性體(41)之長度，原理上彈性體(41)之長度即決定容抵部(22)與容抵塊(421)相脫開時之扭力大小，第一指標(62)係隨調整塊(53)位移，第一指標(62)位移時，感應器(71)係可知位移距離，如此顯示機構(70)知其位移值時即可得知扭力大小。1. The main principle of the present invention is that the length of the elastic body (41) is controlled when the adjusting block (53) is displaced. In principle, the length of the elastic body (41) determines the tolerance portion (22) and the tolerance block (421). The magnitude of the torsion force when the phase is disengaged, the first index (62) is displaced with the adjustment block (53), and when the first index (62) is displaced, the sensor (71) is known to the displacement distance, so that the display mechanism (70) knows The magnitude of the torque can be known from the displacement value.
2、該指標組(60)係設有第一指標(62)及第二指標(63)，該第一指標(62)係與顯示機構(70)得知扳手扭力數值，該第二指標(63)係與數值件(80)相配合對照數值以設定扳手扭力大小，本發明係具數字式或數位式顯示及傳統刻度設定之二種不同方式調整扳手扭力數值，本發明係兼具二種不同調整扳手扭力數值之優點。2. The indicator group (60) is provided with a first indicator (62) and a second indicator (63), wherein the first indicator (62) and the display mechanism (70) are aware of the wrench torque value, and the second indicator ( 63) The value of the wrench is matched with the numerical value (80) to set the torque of the wrench. The present invention has two different ways of adjusting the torque value of the wrench in the digital or digital display and the conventional scale setting, and the present invention has two kinds of Different advantages of adjusting the torque value of the wrench.
3、當使用時，顯示機構(70)耗盡電源而失去得知扭力數值之功效，該指標組(60)之第二指標(63)係可與數值件(80)相配合設定刻度以調整扳手扭力大小。3. When used, the display mechanism (70) runs out of power and loses the effect of knowing the torque value. The second indicator (63) of the indicator group (60) can be adjusted with the numerical value (80) to adjust the scale. Wrench torque.
因此本發明之扭力扳手結構具有產業利用性、新穎性及進步性，誠能符合發明專利之申請要件，爰依法提出申請。Therefore, the structure of the torque wrench of the present invention has industrial utilization, novelty and advancement, and can meet the application requirements of the invention patent, and submits an application according to law.
