Description

Technical Field

[0001] The utility model relates to the technical field of torque wrenches, and more particularly to a digital display torque wrench with a signal transmitting and receiving function. Background Art

[0002] As the name suggests, a digital torque wrench is a torque wrench with a digital display. It is the most advanced type of torque wrench. Not only will the wrench make a "beeping" sound or bend a little at the wrench connection when the applied torque reaches the set value, but it will also prompt the user through a digital display or LED light. The torque setting can also be completed through buttons and digital displays. It is more convenient and easier to operate than non-digital torque wrenches.

[0003] At present, in order to facilitate the recording and viewing of torque values, a signal transceiver module is added to the digital torque wrench. The torque value is recorded on other devices through the signal transceiver module, and other devices can also control the digital torque wrench through the signal transceiver module. However, since the signal transceiver module is large in size, installing it inside the wrench will cause the digital torque wrench to become larger, which is inconvenient to carry and use. Therefore, the utility model proposes a digital torque wrench with a signal transceiver function. Utility Model Content

[0024] Example:

[0025] See also Figure 1-3 A digital torque wrench with a signal transceiver function includes a main rod body 1, one end of the main rod body 1 is detachably connected to a ratchet head 2, a display 3 is fixedly connected to the main rod body 1, a signal transceiver 4 is detachably connected to the display 3, an interface 5 is provided on the display 3, a connector 6 is fixedly connected to the signal transceiver 4, and the connector 6 is plugged into the interface 5, a limiting mechanism is provided on the display 3, and the limiting mechanism is used to limit the signal transceiver 4 to prevent it from falling off.

[0026] In this embodiment, the signal transceiver 4 is plugged into the display 3 through the connector 6 and the interface 5 to complete the electrical connection. The limiting mechanism limits the signal transceiver 4 so that the connection between the signal transceiver 4 and the display 3 remains stable. When used through the main rod body 1 and the ratchet head 2, the display 3 is connected to the signals of other devices through the signal transceiver 4, so that other devices can control the torque and read the numerical values.

[0027] Specifically, the limiting mechanism includes two grooves 71, two T-shaped rods 72, two limiting plates 73 and two springs 74. The two grooves 71 are respectively opened at the symmetrical two side ends of the display 3, and the two T-shaped rods 72 are respectively slidably inserted into the two grooves 71. The two limiting plates 73 are respectively fixedly connected to one end of the two T-shaped rods 72 corresponding to the signal transceiver 4. The two springs 74 are respectively sleeved on the circumferential surface of the two T-shaped rods 72, and the two springs 74 are respectively located in the two grooves 71.

[0028] In this embodiment, after the signal transceiver 4 is connected to the display 3, the two limiting pieces 73 are pulled to make the two T-shaped rods 72 slide in the two grooves 71. The two T-shaped rods 72 compress the two springs 74 respectively, and then the two limiting pieces 73 are rotated to the bottom of the signal transceiver 4 through the two T-shaped rods 72. The two limiting pieces 73 support the bottom of the signal transceiver 4, thereby limiting the signal transceiver 4 and keeping the signal transceiver 4 stable.

[0029] Specifically, two limiting slots 8 are formed on one end of the signal transceiver 4 away from the display 3 , and the two limiting pieces 73 match the two limiting slots 8 respectively.

[0030] In this embodiment, when the two limiting pieces 73 support the bottom of the signal transceiver 4 , the two limiting pieces 73 are respectively located in the two limiting grooves 8 , and the two limiting grooves 8 enable the two limiting pieces 73 to remain stable at the bottom of the signal transceiver 4 .

[0031] Specifically, a limiting protrusion 9 is fixedly connected to the display 3 , and the signal transceiver 4 is located inside the limiting protrusion 9 .

[0032] In this embodiment, the limiting protrusion 9 limits the signal transceiver 4 so that the connection between the signal transceiver 4 and the display 3 remains further stable.

[0033] Specifically, a handle cover 10 is fixedly connected to the circumferential surface of the main rod body 1 , and the handle cover 10 is located on a side of the display 3 away from the ratchet head 2 .

[0034] In this embodiment, the torque wrench is changed by rotating the handle sleeve 10, making the use of the torque wrench more convenient.

[0035] Working principle: The signal transceiver 4 is plugged into the display 3 through the connector 6 and the interface 5 to complete the electrical connection. After the signal transceiver 4 is connected to the display 3, the two T-shaped rods 72 are made to slide in the two grooves 71 by pulling the two limit plates 73. The two T-shaped rods 72 compress the two springs 74 respectively, and then the two limit plates 73 are rotated to the bottom of the signal transceiver 4 through the two T-shaped rods 72. The two limit plates 73 support the bottom of the signal transceiver 4, thereby limiting the signal transceiver 4 and keeping the connection between the signal transceiver 4 and the display 3 stable. When the bolt is torqued through the main rod body 1 and the ratchet head 2, the display 3 is connected to other device signals through the signal transceiver 4, so that other devices can control the wrench torque and read the numerical value.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
