Description

Technical Field

[0001] This utility model relates to a telescopic intelligent torque socket wrench, belonging to the field of manual tool technology. Background Technology

[0002] As a core tool in mechanical repair, automotive maintenance, and equipment assembly, the flexibility of socket wrenches directly impacts work efficiency and applicability. In practical applications, work environments often present space constraints, such as deep-cavity bolts in engine compartments, narrow gaps at pipe connections, and internal fasteners in large equipment. All of these require wrenches to be able to flexibly adjust their length according to the operating distance and available space. However, when disassembling bolts inside deep cavities or near obstacles, the fixed-length wrench housing can easily interfere with surrounding components, making it impossible to accurately fit the socket head onto the bolt. Furthermore, when replacing or repairing vulnerable parts on equipment, the lack of telescopic adjustment in existing socket wrenches prevents direct operation on the target component within confined spaces. Often, it is necessary to first disassemble the entire equipment structure or its surrounding protective plates, pipes, and other related components to create sufficient operating space for repair, increasing the number of steps and reducing operational convenience and efficiency. To address this, a telescopic intelligent torque socket wrench is proposed. Summary of the Invention

[0003] In view of this, the present invention provides a telescopic intelligent torque socket wrench to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0004] The technical solution of this utility model is as follows: a telescopic intelligent torque socket wrench includes an outer tube, an inner tube, a control housing and a drive housing. One end of the outer tube is fixedly connected to the drive housing, the inner tube is slidably connected inside the outer tube, and the end of the inner tube away from the outer tube is fixedly connected to the control housing. A fixed plate is fixedly connected inside the inner tube. A sliding rod is slidably connected inside the fixed plate. Two L-shaped plates are hinged to one end of the sliding rod, and a spring is fixedly connected to the outside of the sliding rod. Both ends of the spring are fixed to the fixed plate. The other end of the sliding rod passes through the fixed plate and is fixedly connected to an adjusting nut. A movable rod is threaded onto the adjusting nut. The inner tube has symmetrical through slots on both sides, and a plug is slidably connected to the inner wall of the through slot. One side of the plug is hinged to an L-shaped plate, and the right angle of the L-shaped plate is hinged to the inner tube. The inner wall of the outer tube has equally spaced slots, and the plug is adapted to the slot.

[0005] More preferably, a motor is installed inside the drive housing, and a torque sensor is fixedly connected to the output end of the motor via a coupling. A sleeve connector is provided inside the drive housing, and the end of the torque sensor away from the motor is fixedly connected to the sleeve connector. A bearing is provided at the connection between the sleeve connector and the drive housing.

[0006] More preferably, the end of the insert block away from the L-shaped plate is wedge-shaped, and the inner wall of the slot is provided with an inclined surface adapted to the insert block.

[0007] More preferably, the control housing contains a battery and a PCB board, the PCB board being electrically connected to the battery, the motor and the torque sensor respectively, and the PCB board integrating a microprocessor and a Bluetooth communication module.

[0008] More preferably, the control housing is provided with a display panel, which is electrically connected to the PCB board, and the display panel is used to display the torque value detected by the torque sensor.

[0009] More preferably, a cylinder is fixedly provided inside the control housing. The cylinder is arranged along the axial direction of the movable rod, and the end of the movable rod away from the adjusting nut passes through the cylinder and extends to the outside of the control housing.

[0010] More preferably, the sleeve connector is provided with a magnet.

[0011] The present invention has the following advantages due to the adoption of the above technical solution: This invention utilizes the sliding fit between the outer and inner tubes, combined with the matching and locking structure of the insert and slot, to flexibly adjust the overall length of the wrench. It allows for operation in confined spaces without disassembling the equipment's outer protective plate, pipes, or other related components, effectively solving the problem of traditional fixed-length wrenches requiring complete disassembly. This significantly reduces maintenance steps and improves operational convenience. Simultaneously, the motor and torque sensor integrated within the drive housing process torque data in real time via a microprocessor on the PCB board. This not only reduces manual labor through electric auxiliary drive but also precisely controls torque output, preventing damage to parts caused by over-tightening or under-tightening, thus improving assembly and maintenance accuracy.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, this utility model embodiment provides a telescopic intelligent torque socket wrench, including an outer tube 10, an inner tube 20, a control housing 30, and a drive housing 40. In one embodiment, one end of the outer tube 10 is fixedly connected to the drive housing 40, the inner tube 20 is slidably connected to the inside of the outer tube 10, and the end of the inner tube 20 away from the outer tube 10 is fixedly connected to the control housing 30; a fixed plate 22 is fixedly connected inside the inner tube 20, a slide rod 23 is slidably connected inside the fixed plate 22, one end of the slide rod 23 is hinged to two L-shaped plates 25, and a spring piece 24 is fixedly connected to the outside of the slide rod 23. The two ends of the spring piece 24 are fixed to the fixed plate 22, and the other end of the slide rod 23 passes through the fixed plate 22 and is fixedly connected to an adjusting nut 28. A movable rod 29 is threaded onto the adjusting nut 28; through slots 21 are symmetrically opened on both sides of the inner tube 20, and insert blocks 27 are slidably connected to the inner wall of the through slots 21. One side of the insert block 27 is hinged to the L-shaped plate 25, and the right angle of the L-shaped plate 25 is hinged to the inner tube 20; slots 11 are evenly distributed on the inner wall of the outer tube 10, and the insert blocks 27 are adapted to the slots 11; Turning the adjustment knob 33 rotates the movable rod 29, which in turn drives the slide rod 23 to slide axially along the fixed plate 22 through the threaded engagement with the adjustment nut 28. When the slide rod 23 slides, it presses or releases the spring piece 24, and at the same time drives the L-shaped plates 25 at both ends to rotate around the right-angle hinge point. When the slide rod 23 slides towards the control housing 30, the L-shaped plate 25 pulls the insert 27 inward along the through groove 21, disengaging it from the slot 11 of the outer tube 10. At this time, the inner tube 20 can slide freely within the outer tube 10 to adjust its length. After the length adjustment is completed, turning the adjustment knob 33 in the opposite direction resets the spring piece 24, pushing the slide rod 23 to slide in the opposite direction. The L-shaped plate 25 pushes the insert 27 to extend and engage with the corresponding slot 11 of the outer tube 10, thus locking the length.

[0023] In one embodiment, a motor 41 is installed inside the drive housing 40, and a torque sensor 42 is fixedly connected to the output end of the motor 41 via a coupling. A sleeve connector 44 is provided inside the drive housing 40, and the end of the torque sensor 42 away from the motor 41 is fixedly connected to the sleeve connector 44. A bearing 43 is provided at the connection between the sleeve connector 44 and the drive housing 40. The end of the insert 27 away from the L-shaped plate 25 is wedge-shaped, and the inner wall of the slot 11 is provided with an inclined surface adapted to the insert 27. Battery 34 powers motor 41, which transmits power to torque sensor 42 via coupling. Torque sensor 42 then transmits power to sleeve connector 44, causing the sleeve fitted on the connector to rotate for fastening and disassembling. Torque sensor 42 detects the torque value during transmission in real time and transmits the signal to PCB board 35. Meanwhile, the wedge-shaped structure of insert 27 engages with the inclined surface of slot 11, allowing insert 27 to automatically align with slot 11 during locking via the inclined guide, reducing the risk of jamming. Bearing 43 reduces friction between sleeve connector 44 and drive housing 40 during rotation, ensuring smooth power transmission.

[0024] In one embodiment, the control housing 30 contains a battery 34 and a PCB board 35. The PCB board 35 is electrically connected to the battery 34, the motor 41, and the torque sensor 42, and integrates a microprocessor and a Bluetooth communication module. The control housing 30 has a display panel 32, which is electrically connected to the PCB board 35 and is used to display the torque value detected by the torque sensor 42. A cylindrical body 31 is fixedly installed inside the control housing 30. The cylindrical body 31 is arranged along the axial direction of the movable rod 29, and the end of the movable rod 29 away from the adjusting nut 28 passes through the cylindrical body 31 and extends to the outside of the control housing 30. An adjusting knob 33 is fixedly connected to the end of the movable rod 29 extending to the outside of the control housing 30. The movable rod 29 is rotatably connected to the inner wall of the cylindrical body 31. A magnet 45 is provided on the sleeve connector 44. The microprocessor on the PCB board 35 receives the torque signal transmitted by the torque sensor 42, processes it, converts it into digital information, and sends it to the display panel 32 for users to view the torque value in real time; the Bluetooth communication module can wirelessly transmit torque data to external terminals such as mobile phones and tablets to realize data recording and traceability; the battery 34 continuously supplies power to electronic components such as the PCB board 35, motor 41, and display panel 32; the cylinder 31 is set along the axial direction of the movable rod 29, which guides the rotation and sliding of the movable rod 29 and prevents it from deviating; the magnet 45 on the sleeve connector 44 can attract the sleeve and prevent the sleeve from falling off during disassembly and assembly.

[0025] When this utility model is in operation: First, adjust the length of the wrench according to the working space requirements. Turn the adjustment knob 33 to drive the movable rod 29 to rotate. The movable rod 29 drives the slide rod 23 to slide along the fixed plate 22 through the threaded engagement with the adjustment nut 28. The slide rod 23 pulls the L-shaped plate 25 to rotate, causing the insert 27 to retract along the through groove 21 and disengage from the slot 11 of the outer tube 10. Then, push or pull the control housing 30 to drive the inner tube 20 to slide within the outer tube 10 to the appropriate length. Turn the adjustment knob 33 in the opposite direction, and the spring piece 24 resets and pushes the slide rod 23 to move in the opposite direction. The L-shaped plate 25 pushes the insert 27 to extend and engage with the corresponding slot 11, thus completing the length locking.

[0026] After length adjustment, fit the appropriate sleeve into the sleeve connector 44. The magnet 45 on the sleeve connector 44 attracts the sleeve to prevent it from falling off. Start the motor 41 by pressing the operation button next to the display panel 32 on the control housing 30. The battery 34 supplies power to the motor 41, PCB board 35 and torque sensor 42. The motor 41 transmits power to the torque sensor 42 through the coupling, and then transmits it to the sleeve connector 44 through the torque sensor 42, driving the sleeve to rotate to realize the installation and removal of bolts / nuts.

[0027] During operation, the torque sensor 42 detects the torque value in real time and transmits the signal to the PCB board 35. The microprocessor on the PCB board 35 processes the signal and displays it on the display panel 32 for real-time monitoring by the operator. Simultaneously, the Bluetooth communication module can wirelessly transmit the torque data to an external terminal for recording and tracking. If torque adjustment or stopping operation is required, the motor 41 can be started / stopped or its mode switched via the display panel 32. After operation, the power is turned off, and the sleeve is removed. The entire process requires no disassembly of external components, making operation convenient and torque control precise, suitable for various confined space operation scenarios.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
