Abstract

The utility model relates to a lighting structure of a torque wrench. The lighting structure of the torque wrench comprises a torque wrench main body, an adjustable grab handle and a numerical value indicator. The numerical value indicator is sheathed and arranged at a proper position of the end edge of a shaft handle of the torque wrench main body, a lighting device which is composed of a light bulb, batteries and a control switch is arranged in the numerical value indicator, wherein, the light bulb is arranged on one side of a slotted hole position of an inner edge of a viewing face, the batteries are contained in a battery chamber which is arranged at the opposite side, and the outer edge is provided with a control switch which is connected. By this design, the torque wrench can produce illuminated efficacy when the utility model is in torque force regulated time, and the torque wrench can be convenient to operate in a place which is provided with an unideal lighting device.

Description

The light structures of torque spanner

The utility model relates to a kind of light structures of torque spanner, refers in particular to a kind of torque spanner light structures simple in structure, easy to use.

Since the human own civilization, hand-held tool promptly occupies a tiny space, wherein spanner promptly is an example, and the use of spanner is for now industry development, indispensable competent assistant especially, its pattern, kind also is various different variations, as combination wrench, double offset ring spanner, ratchet spanner, monkey wrench or the like, wherein when pulling, the spanner that can predict the torque value size is a torque spanner, this kind torque spanner mostly is the important mechanism place that is applied to the torque value palpus maintenance certain limit of nut locking place, its rear end is provided with a rotatable adjustment lever of adjusting torque magnitude, be equipped with a numerical value display that can show torsion numerical value and adjust the lever front end sleeve, represent numerical values recited by the scale on the display, and because this kind torque spanner in when operation, the operating personnel must watch the numerical value of torsion often, therefore, if the place lighting position relatively poor or screw lock of operation is comparatively steady when close, then often can't clearly see the numerical value of demonstration clearly, and then cause the operational inconvenience of user, so improved necessity is in addition arranged.

Main purpose of the present utility model promptly is to address the above problem and a kind of light structures of torque spanner is provided, and makes torque spanner when carrying out the adjustment of torsion, can produce the effect of illumination in good time.

For achieving the above object, the utility model is achieved in that a kind of light structures of torque spanner, mainly comprise a torque spanner main body, an adjustment lever and a numerical value display, wherein, the numerical value display is placed on the appropriate location of the footstalk end of wrench body, be characterized in: the inside of this numerical value display is equiped with one by lighting device that bulb, battery and gauge tap constituted, wherein, this bulb is arranged at a side and sees the slotted eye place of looking the face inner edge, battery is placed in the battery chamber of opposite side, and in its outer rim one gauge tap that is connected is set.

Positive progressive effect of the present utility model is by arranged illumination devices, makes torque spanner when the not good environment of sight line is adjusted torque value, can produce the effect of illumination, and have more the value that industry is utilized.

Accompanying drawing of the present utility model is simply described as follows:

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is a decomposing schematic representation of the present utility model.

Fig. 3 is a partial elevation view of the present utility model.

Fig. 4 is a combination section of the present utility model.

Fig. 5 is a circuit diagram of the present utility model.

Below in conjunction with accompanying drawing, provide a preferred embodiment, the utility model is done one describe in detail.

Seeing also Fig. 1～Fig. 5, is the structure of the selected a kind of embodiment of the utility model shown in the figure, and this only for the usefulness of explanation, is not subjected to the restriction of this kind structure in patent application.

Please referring to Fig. 1～shown in Figure 4, the light structures of the utility model torque spanner comprises that mainly a torque spanner main body 1, adjusts a lever 2 and a numerical value display 3, wherein:

This torque spanner main body 1, have a pulling part 11 and footstalk 12, footstalk 12 is the vertical bar shape, can make adjustment lever 2 be placed on the ora terminalis appropriate location with numerical value display 3, its inner rim is placed with torsion control structure (not shown), and is connected with pulling part 11 and adjustment lever 2 respectively.

This adjusts lever 2, is set in the terminal edge place of torque spanner main body 1, can adjust torque magnitude.

This numerical value display 3, the blocks that is wedge, be placed on the near-end edge place of torque spanner main body 1, inside is equiped with one by bulb 41, the lighting device 4 that battery 42 and gauge tap 43 are constituted, make torque spanner when carrying out the adjustment of torsion, can produce the effect of illumination in good time, wherein, this bulb 41 is arranged at numerical value display 3 one sides and sees slotted eye 32 places of looking face 31 inner edges, battery 42 then is placed in the battery chamber 33 of its opposite side, simultaneously, and one gauge tap that is connected 43 is set, with the switch of control bulb 41 in its outer rim, like this, make torque spanner when the not good place operation of lighting apparatus, still can see the torque value on the graduation apparatus easily clearly, and the situation that does not have an erroneous judgement takes place.

By above-mentioned explanation as can be known, the utility model utilizes a side of numerical value display 3 to see and looks in the slotted eye 32 of face 31 inner edges, be equiped with bulb 41 respectively, device battery 42 in the battery chamber 33 of its opposite side again, simultaneously, in its outer rim one gauge tap that is connected 43 is set, can make torque spanner when carrying out the adjustment of torsion, produce the effect of illumination in good time, and have more the value that industry is utilized, during use, only must stir gauge tap 43 and can make bulb produce the effect of illumination, what must be illustrated is that gauge tap 43 of the present utility model can be located at one-sided or the dual-side appropriate location, the setting of its circuit can have four kinds of modes, please referring to shown in Figure 5, its mode comprises: the single switch of 5-1, single bulb, the single switch of 5-2, two bulbs, the 5-3 biswitch, two bulbs (single bulb is bright), the 5-4 biswitch, two bulbs (two bulbs are bright).Make the switch of bulb have more practical effect like this.

The above embodiment is in order to explanation the utility model, is not in order to restriction the utility model, so the displacement of the change of numerical value or equivalence element must belong to category of the present utility model such as.
