Description

Digital torsion post structure

The invention relates to a digital torsion post structure, in particular to a post structure which is guided between the wrench head and the sleeve to detect the torque value during the reciprocating driving, and the display screen has an adjustment display direction. Facilitate the ability to interpret torque data.

According to the technical field of mechanical assembly, bolts and nuts are used to lock various components, which is a relatively well-known fixing method. However, because each person's feeling of strength is not the same, and some special combinations are not as tight as possible, so there is a torque wrench to ask the market, so that every screw lock operation, even in different people Under the operation, the same torque requirement can also be achieved; however, the torque wrench has a pure mechanical design. When the user applies a force close to the preset torque value, the torque wrench will generate a swinging feel. The user is reminded that there is also an electronic torque wrench with a display module for the user to obtain information about the torque value through the display module.

Please refer to the "Digital Torque Post" of the Patent No. M392714 of the Republic of China, which mainly comprises a torsion post having a first adapter body and a second adapter body, the first transfer The rod body has a first joint portion and a first joint portion. The first joint portion is sleeved on an object to be turned, and the second adapter rod body has a second joint portion and a second joint portion. The second joint portion is sleeved on a torque tool, and the second joint portion is detachably connected to the first joint portion; a sensing element is fixed to the torque rod a peripheral surface for sensing a torque value applied by the user to the torsion post to transmit a telecommunication signal; a digital display unit electrically connected to the sensing element to receive the telecommunication signal output by the sensing element And the number is displayed.

The aforementioned creator has applied for the creation of the case, which is a digital torsion post that is tapped to the sleeve and the wrench through the first adapter body and the second adapter body. At the time of turning, the torque component is measured by the sensing component; however, the digital display unit of the previous case is fixedly disposed on the adapter body, and when the operator pulls the adapter bar, the screen of the digital display unit also rotates synchronously. It is inconvenient for the operator to move the body to obtain the perspective of the torque data.

In view of this, the present inventors have intensively discussed the above-mentioned conventional creation problems, and actively pursued solutions through years of experience in research and development and manufacturing of related industries. After long-term efforts in research and development, the present invention has finally succeeded in developing the present invention. "Digital Torque Post Structure", which is a post structure that is connected between the wrench head and the sleeve to detect the torque value during the cranking drive, and the display screen is unaffected by the rotation of the post. Fixed point display effect.

The invention relates to a digital torsion post structure, which is a post structure which is connected between a wrench head and a sleeve to detect a torque value when the driving is driven, and the display screen has an adjustment display direction for convenience. The function of interpreting torque data.

In order to achieve the above-mentioned creative purpose, the "digital torsion post structure" of the present invention comprises a post body, a housing portion and a positioning assembly. The post system has a connecting portion for the torque wrench to be engaged, and a The sleeve body has a shaft portion between the connecting portion and the driving portion, the rod body is provided with a positioning pin on the outer surface, and the housing portion has an upper cover body and a lower cover body The housing portion is a rotatable type sleeve that is sleeved on the shaft body of the post body. The inner side of the housing portion is formed with an inner ring groove through which the positioning pin is inserted. The positioning component is an arc-shaped elastic plastic body. The positioning component is disposed on the inner ring groove, and the inner side of the positioning component is formed with a plurality of teeth convex for the positioning pin to abut, and the housing part is provided with a digital torque display unit.

In this way, through the housing portion being rotated relative to the post body, during the rotation operation of the post body, the operator can adjust the corresponding direction of the housing portion at any time, so as to instantly interpret the torque data, and the positioning pin is obtained from the plurality of teeth. When the convex portion bounces, when the housing portion stops rotating, the positioning pin can be abutted against the gap of the tooth convex to achieve a false positioning effect.

The casing portion is formed with a card protrusion at each of the two ends of the inner ring groove, and the two ends of the positioning component are respectively folded back to have a positioning portion which is buckled.

A tire pressure detector is disposed on one side of the casing portion.

It can be seen from the above description that the "digital torsion post structure" of the present invention has a housing portion and a post body that are relatively rotatable. When the operator completes the turning operation, the angle of the digital torque display unit can be adjusted through the rotating outer casing. Therefore, the operator can quickly interpret the torque data without moving the body, and the invention has a more flexible operation space than the digital torque adapter without the rotary adjustment angle of view; therefore, the invention can be said to be quite practical. And the progressive creation is quite worthy of promotion by the industry and publicized to the public.

The invention relates to a digital torsion post structure, which is a post structure which is connected between a wrench head and a sleeve to detect a torque value when the driving is driven, and the display screen has an adjustment display direction for convenience. For the function of the torque data, please refer to the first to fourth figures. The "digital torsion post structure" of the present invention comprises a post body 1, a housing portion 2 and a positioning assembly 3; the post body The 1 series has a connecting section 11 for the torque wrench to be engaged, and a driving section 12 for the sleeve to be engaged. The connecting rod body 1 has a shaft section 13 between the connecting section 11 and the driving section 12, and the connecting rod body 1 A positioning pin 14 is disposed on the outer surface. The embodiment is disposed on the outer surface of the proximal connecting portion 11 and is represented by two positioning pins 14; the housing portion 2 has an upper cover 21 and a lower cover 22 The housing portion 2 is sleeved on the shaft portion 13 of the post body 1 in a rotatable manner. The cover body 21 and the lower cover body 22 are disposed on the outer surface of the post body 1 in a cover manner.
