Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically to a torque intelligent detection wrench. Background Technology

[0002] In the construction of high-strength bolts in steel structures, the most important aspect is ensuring that all high-strength bolt connections reach the design preload specified in the design code. Excessive preload can cause necking and elongation of the high-strength bolts, and may also lead to delayed fracture some time after construction, creating safety hazards. Insufficient preload will reduce the connection strength of the structure, posing risks to its alignment and stability. A wrench is a commonly used installation and disassembly tool, a hand tool that uses leverage to tighten or loosen bolts, screws, nuts, and other threaded fasteners. Wrenches are typically made of carbon or alloy structural steel. They usually have openings or sockets at one or both ends of the handle to hold the bolt or nut. When using a wrench, applying external force along the direction of thread rotation to the handle allows for tightening or loosening of the bolt or nut.

[0003] Most wrenches on the market have fixed bits and can only be used for one type of bolt. However, if a wrench that can monitor torque can only be used for one type of bolt, its scope of application will be narrowed. Utility Model Content

[0004] The purpose of this invention is to provide a torque intelligent detection wrench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a torque intelligent detection wrench, including a wrench handle, a detection mechanism installed at one end of the wrench handle, a handle fixedly connected to the other end of the wrench handle, a battery slot formed on one outer wall of the wrench handle, and a battery being snapped into the inner wall of the battery slot, the detection mechanism including a wrench head fixedly connected to the wrench handle, and an installation opening formed on one outer wall of the wrench head, a torque sensor fixedly installed on the inner wall of the installation opening, and a connecting post fixedly connected to the bottom of the torque sensor, with a screwdriver bit installed on the connecting post.

[0006] Preferably, the bottom outer wall of the bit has a second groove, and the top outer wall of the bit has a second connecting post. The second groove facilitates engagement between the bit and the bolt head, making it easy to tighten the bolt with a wrench. The second connecting post also facilitates the installation of the bit.

[0007] Preferably, the bottom outer wall of the connecting post one is provided with a ridge groove one, and the inner walls on both sides of the ridge groove one are provided with limiting grooves. The specifications of the connecting post two match the specifications of the ridge groove one. The ridge groove one at the bottom of the connecting post one facilitates the direct insertion of the connecting post two. The two limiting grooves facilitate the fixing of the connecting post two. The detachable bit facilitates its replacement.

[0008] Preferably, the second connecting post has an internal mounting cavity, and both sides of the inner wall of the mounting cavity have strip-shaped openings. The inner walls of the two strip-shaped openings are slidably connected to T-shaped limiting blocks, and the specifications of the limiting blocks match the specifications of the limiting grooves. The opening of the mounting cavity and the strip-shaped openings facilitates the sliding installation of the limiting blocks. When the limiting blocks extend, they are directly inserted into the limiting grooves, thereby facilitating the fixing of the second connecting post. At the same time, the adjustable limiting blocks facilitate the replacement of the bit.

[0009] Preferably, two mounting rods are fixedly connected to the inner walls of both sides of the mounting cavity, and springs are sleeved on the outer walls of the four mounting rods. Two limiting blocks are slidably connected to the outer walls of the four mounting rods respectively. The springs on the mounting rods facilitate pushing the limiting blocks out. Under normal conditions, the springs drive the limiting blocks out and insert them into the limiting grooves, thereby ensuring the stability of the limiting blocks and preventing the installed bit from falling off.

[0010] Preferably, the inner wall of the mounting cavity is rotatably connected to a drive arm, and the outer wall of the drive arm is rotatably connected to two connecting rods. One end of each connecting rod is rotatably connected to two limiting blocks. The top inner wall of the second prism is provided with a circular groove, and the inner wall of the circular groove is rotatably connected to a rotating part. One end of the drive shaft of the rotating part is fixedly connected to the drive arm. When the limiting blocks need to be adjusted, rotating the rotating part drives the drive arm to rotate. When the drive arm rotates clockwise, it pulls the two limiting blocks to move towards each other in coordination with the connecting rods. When the limiting blocks are retracted into the mounting cavity, the bit can be removed. When the rotating part is released, the spring returns to its original position and drives the limiting blocks to extend. The rotating part has a prism structure.

[0011] Preferably, the top outer wall of the wrench handle has a groove, and the inner wall of the groove is fixedly connected to a display panel. The display panel is electrically connected to the battery and the torque sensor. The groove facilitates the installation of the display panel, and the display panel can conveniently display the torque value fed back by the torque sensor in real time.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a detection mechanism on the wrench, the torque sensor in the detection mechanism facilitates torque detection. The cooperation between connecting column one and connecting column two in the detection mechanism facilitates quick replacement of the bit, solving the problem of inconvenient bit replacement in existing torque detection wrenches. The rotating part facilitates manual rotation of the drive arm, thereby facilitating adjustment of the position of the limit block. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution:

[0022] like Figures 1-6 The torque intelligent detection wrench shown includes a wrench handle 1, a detection mechanism 4 installed at one end of the wrench handle 1, and a handle 3 fixedly connected to the other end of the wrench handle 1. A battery slot is formed on one outer wall of the wrench handle 1, and a battery 5 is snapped into the inner wall of the battery slot. The detection mechanism 4 includes a wrench head 6 fixedly connected to the wrench handle 1, and an installation port is formed on one outer wall of the wrench head 6. A torque sensor 7 is fixedly installed on the inner wall of the installation port, and a connecting post 8 is fixedly connected to the bottom of the torque sensor 7. A screwdriver bit 11 is installed on the connecting post 8.

[0023] In this embodiment, the wrench lever 1 is designed to facilitate the installation of the detection mechanism 4. The detection mechanism 4 can detect the torque in real time when tightening the bolt. The handle 3 at the other end of the wrench lever 1 is easy to grip. The battery 5 is designed to provide power to the torque sensor 7 in the detection mechanism 4. The connecting post 8 is designed to facilitate the installation of the auxiliary bit 11. The torque sensor 7 is designed to detect the torque of the wrench in real time, so as to avoid damage to the bolt when the wrench is used to assist in the installation of the bolt, and also to protect the wrench and extend its service life.

[0024] like Figures 3-5 The bit 11 shown has a groove 12 on the bottom outer wall and a connecting post 13 on the top outer wall. The connecting post 18 has a groove 9 on the bottom outer wall and a limit groove 10 on both sides of the inner wall. The specifications of the connecting post 13 and the groove 19 are matched.

[0025] In this embodiment, the second groove 12 on the bit 11 facilitates engagement with the bolt, the connection between the second connecting post 13 and the first groove 9 facilitates the installation of the bit 11, the limiting groove 10 facilitates the installation of the second connecting post 11, and the second connecting post 13 is a prism structure, thus avoiding slippage between the bit 11 and the first connecting post 8, ensuring the stability of the bolt connection, and preventing the bit 11 from slipping and damaging the bolt when rotating.

[0026] like Figures 4-6 The connecting column 13 shown has an internal mounting cavity 16, and both sides of the inner wall of the mounting cavity 16 have strip-shaped openings. The inner walls of the two strip-shaped openings are slidably connected to T-shaped limiting blocks 14, and the specifications of the limiting blocks 14 match the specifications of the limiting groove 10. Both sides of the inner wall of the mounting cavity 16 are fixedly connected to two mounting rods 17, and the outer walls of the four mounting rods 17 are sleeved with springs 18. The two limiting blocks 14 are slidably connected to the outer walls of the four mounting rods 17 respectively. The inner wall of the mounting cavity 16 is rotatably connected to a drive arm 19, and the outer wall of the drive arm 19 is rotatably connected to two connecting rods 20. One end of the two connecting rods 20 is rotatably connected to the two limiting blocks 14 respectively. The top inner wall of the ridge groove 12 has a circular groove, and the inner wall of the circular groove is rotatably connected to a rotating part 15. One end of the drive shaft of the rotating part 15 is fixedly connected to the drive arm 19.

[0027] In this embodiment, when the bit 11 needs to be disassembled, a socket wrench is first attached to the rotating part 15. The rotating part 15 has a regular hexagonal cross section, which is convenient for use with the socket wrench. The rotating part 15 is protected by a circular groove to prevent it from being exposed and affecting the connection of the bolt. When the rotating part 15 drives the drive arm 19 to rotate clockwise, it directly pulls the two limit blocks 14 to move towards each other through the two connecting rods 20. When the limit blocks 14 are disengaged from the limit groove 10, the connecting post 2 13 can be disassembled from the ridge groove 2 12. When the two limit blocks 14 move towards each other, the springs 18 on the four mounting rods 17 are compressed. When the rotating part 15 is released, the limit blocks 14 can be reset and extended. At the same time, the setting of multiple springs 18 drives the limit blocks 14 to be stably inserted into the limit groove 10, preventing the limit blocks 14 from disengaging from the limit groove 10 later, which would cause the bit 11 and the wrench head 6 to separate.

[0028] like Figures 1-2 The top outer wall of the wrench lever 1 shown has a groove, and the inner wall of the groove is fixedly connected to the display panel 2. The display panel 2 is electrically connected to the battery 5 and the torque sensor 7.

[0029] In this embodiment, the real-time torque value is conveniently displayed through the setting of the display panel 2.

[0030] Working principle: In use, first install the bit 11 on the connecting post 8. Before installation, connect it to the rotating part 15 using a socket wrench. When the rotating part 15 drives the drive arm 19 to rotate clockwise, it directly pulls the two limit blocks 14 to move towards each other through the two connecting rods 20. At this time, the limit blocks 14 compress the spring 18 on the mounting rod 17. When the two limit blocks 14 are retracted into the mounting cavity 16, insert the connecting post 13 into the ridge groove 9. When the connecting post 13 is fully inserted into the ridge groove 9, release the rotating part. The moving part 15 and the spring 18 reset and push the two limit blocks 14 into the limit groove 10 to install the bit 11. At the same time, the setting of multiple springs 18 drives the limit blocks 14 to be stably inserted into the limit groove 10, so as to prevent the limit blocks 14 from disengaging from the limit groove 10 later, which would cause the bit 11 and the wrench head 6 to separate. When tightening the bolt with the wrench, the second groove 12 is engaged with the bolt. When the wrench lever 1 is manually rotated, the torque value fed back by the torque sensor 7 can be monitored in real time through the display panel 2.
