Description

Technical Field

[0001] This utility model relates to the field of torque detection technology, and in particular to a digital torque wrench. Background Technology

[0002] In some scenarios, bolt tightening requires strict torque control to ensure engine sealing and reliability. A digital torque wrench is necessary for this purpose for the following reasons: First, it allows for precise torque control, as many industrial and mechanical applications have stringent requirements on the tightening torque of bolts, nuts, and other fasteners. Second, it provides data recording capabilities; digital torque wrenches typically record information such as the torque value, tightening time, and operator for each tightening operation.

[0003] A digital torque wrench typically consists of a wrench body, a torque sensor, a digital display screen, and a wrench head. The wrench body is usually made of high-strength engineering plastics or metal materials, serving to protect the internal components and provide a mounting base for other parts. The wrench head is the part that directly contacts the bolt or nut, and its shape and size need to match different specifications of bolts or nuts. It is also fixed together with screws and bolts.

[0004] Existing digital torque wrenches install the torque head by aligning the grooves in the wrench body with the torque head and then tightening the bolt or screw using a specific tool. However, this fixing method requires a corresponding screwdriver or wrench, making the operation cumbersome. When frequent torque head replacements are needed, it consumes a lot of time and reduces work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a digital torque wrench, which aims to improve the problem that the existing technology is relatively cumbersome to operate, and consumes a lot of time and reduces work efficiency when the torque head needs to be changed frequently.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a digital torque wrench, comprising a wrench body, a torque head at one end of the wrench body, and a portable component at the other end of the wrench body. The portable component facilitates operation of the wrench body. A connecting sleeve is fixedly connected to the torque head near the wrench body, and a fixing component is provided inside the connecting sleeve. The fixing component includes a pressing block, one side of which is fixedly connected to the inner wall of the connecting sleeve. A slider is slidably connected to the outer wall of the pressing block, and an mounting block is slidably connected to the outer wall of the slider. A limit ring is fixedly connected inside the mounting block, and an elastic ball is fixedly connected inside the pressing block. A slot is provided on the inner wall of the mounting block, and the end of the elastic ball is slidably connected inside the slot.

[0007] Furthermore, the portable component includes a handle, one end of which is fixedly connected to the other end of the wrench body, and a soft pad is fixedly connected to the outer wall of the handle.

[0008] Furthermore, a connecting rod is fixedly connected to one end of the wrench body, a guide ring is rotatably connected to the outer wall of the connecting rod, a second connecting block is slidably connected inside the guide ring, and a second slider is fixedly connected to one end of the second connecting block.

[0009] Furthermore, the outer wall of the second slider is slidably connected to the guide ring, and a first connecting block is fixedly connected to one side of the guide ring.

[0010] Furthermore, the outer wall of the extrusion block is slidably connected to the inner wall of the mounting block, and the outer wall of the mounting block is slidably connected to the inner wall of the connecting sleeve.

[0011] Furthermore, the outer wall of the slider is slidably connected within the groove of the connecting sleeve, and the outer wall of the slider is slidably connected to the limiting ring.

[0012] Furthermore, a display screen is fixedly connected to the outer wall of the wrench body.

[0013] Furthermore, a control panel is fixedly connected to the outer wall of the wrench body.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by inserting the mounting block into the connecting sleeve, the slider is pushed out of the mounting block by the squeezing block, so that it is stuck in the groove of the connecting sleeve. In this way, the connecting sleeve and the connecting block can be fixed together. The fixing method does not require the use of specific tools for installation, reducing the time required for replacing the twist head. Moreover, the squeezing block is equipped with an elastic ball. The squeezing of the mounting block can make the ball return to the cavity. When aligned with the slot, the ball returns to its original position and is stuck in the slot. This can strengthen the fixing of the twist head and prevent it from falling off.

[0016] 2. In this utility model, by installing a connecting rod, the guide ring can rotate on the outer wall of the connecting rod. By rotating the connecting rod, the wrench can be turned on bolts in different directions. When encountering nuts with tricky angles, the slider can be pushed to rotate on the outer wall of the guide ring, thereby achieving the effect of adjusting the angle. This is used to tighten bolts in different positions, making it convenient for workers to perform fixing operations and optimizing the user experience of the wrench. Attached Figure Description

[0022] 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.

[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a digital torque wrench, including a wrench body 1. One end of the wrench body 1 is provided with a torque head 8, which facilitates the tightening of nuts. The other end of the wrench body 1 is provided with a portable component for convenient operation. A connecting sleeve 7 is fixedly connected to the side of the torque head 8 near the wrench body 1, providing conditions for the installation of the torque head 8. A fixing component is provided inside the connecting sleeve 7; the fixing component includes a pressing block 12, one side of which is fixedly connected to the inner wall of the connecting sleeve 7. The connection between the pressing block 12 and the connecting sleeve 7 allows the pressing block 12 to move together with the connecting sleeve 7. The outer wall of the pressing block 12... A slider 13 is slidably connected. The slider 13 can be compressed and spread outwards by the movement of the compression block 12. A mounting block 18 is slidably connected to the outer wall of the slider 13, facilitating fixing and other operations. A limit ring 14 is fixedly connected inside the mounting block 18 to prevent the slider 13 from falling into its interior. An elastic ball 11 is fixedly connected inside the compression block 12, providing the necessary conditions for fixing the compression block 12 to the mounting block 18. A slot 16 is formed on the inner wall of the mounting block 18, and the end of the elastic ball 11 is slidably connected inside the slot 16. By engaging the elastic ball 11 in the slot... The interior of 16 allows for the fixing of the mounting block 18 and the pressing block 12, strengthening the fixation of the twisting head 8. The portable component includes a handle 2, one end of which is fixedly connected to the other end of the wrench body 1. The handle 2 facilitates the operator's operation of turning the twisting head 8. A soft pad 3 is fixedly connected to the outer wall of the handle 2. The soft pad 3 not only prevents damage to the handle 2 due to external impacts but also protects the operator's hands from injury caused by the squeezing and friction generated when turning the wrench. The outer wall of the pressing block 12 is slidably connected to the inner wall of the mounting block 18. By slidably connecting the pressing block 12 inside the mounting block 18, it facilitates the fixing operation of the elastic ball 11. The outer wall of the mounting block 18 is slidably connected to the inner wall of the connecting block 18. The inner wall of the connecting sleeve 7 and the outer wall of the slider 13 are slidably connected in the groove of the connecting sleeve 7. The connecting sleeve 7 and the wrench body 1 can be connected by the slider 13 sliding in the groove of the connecting sleeve 7. The outer wall of the slider 13 is slidably connected to the limiting ring 14. The slider 13 sliding in the limiting ring 14 can prevent it from falling into the interior of the mounting block 18 and causing the operation to be impossible. The outer wall of the wrench body 1 is fixedly connected to the display screen 4, which is used to display the measured torque value, related setting information and working status in real time. The outer wall of the wrench body 1 is fixedly connected to the control panel 10, which can be used to set the torque value, switch the measurement mode, zero, switch on and off and other operations.

[0024] Reference Figure 1 and Figure 2One end of the wrench body 1 is fixedly connected to a connecting rod 9. Installing the connecting rod 9 at one end of the wrench body 1 creates conditions for the rotation of the guide ring 5. The outer wall of the connecting rod 9 is rotatably connected to the guide ring 5. The connection between the guide ring 5 and the connecting rod 9 allows adjustment of the orientation of the twisting head 8. The guide ring 5 is slidably connected to a connecting block 2 15. The connecting block 2 15 provides support and guidance for the rotation of the slider 2 17. One end of the connecting block 2 15 is fixedly connected to a slider 2 17. The connection between the slider 2 17 and the connecting block 2 15 allows the connecting block 2 15 to rotate together with the slider 2 17. The outer wall of the slider 2 17 is slidably connected to the guide ring 5. The connection between the slider 2 17 and the guide ring 5 allows adjustment of the angle of the twisting head 8, enabling it to be turned on nuts with tricky angles. One side of the slider 2 17 is fixedly connected to a connecting block 1 6. The connection between the slider 2 17 and the connecting block 1 6 allows the twisting head 8 to rotate with the slider 2 17.

[0025] Working Principle: Before using the wrench, some preparatory work is required. When installing the twist head 8, insert the mounting block 18 into the connecting sleeve 7. At this time, the pressing block 12 fixed on the inner wall of the connecting sleeve 7 will press the slider 13 as the connecting sleeve 7 is inserted. Under the action of the pressing block 12, the slider 13 will spread outwards, and its outer wall will slide into the groove of the mounting block 18 and the connecting sleeve 7, thereby making the slider 13 stuck in the groove of the connecting sleeve 7, achieving the initial fixation of the connecting sleeve 7 and the mounting block 18. When the elastic ball 11 inside the pressing block 12 is compressed during the insertion of the mounting block 18, it retracts into the cavity. When the mounting block 18 is fully inserted, the elastic ball 11 will align with the slot 16 on the inner wall of the mounting block 18. Under its own elastic force, the elastic ball 11 will pop out of the cavity, and the end of the ball will slide into the interior of the slot 16, thereby further reinforcing the fixation of the twist head 8 and effectively preventing it from falling off during use. When encountering nuts with tricky angles during operation... An angle adjustment device is required. It is connected to the guide ring 5 by a connecting rod 9 installed at one end of the wrench body 1. When the direction of the torque head 8 needs to be adjusted to accommodate bolts with different orientations, the guide ring 5 can rotate around the outer wall of the connecting rod 9. In this way, the torque head 8 connected to the guide ring 5 can change its orientation with the rotation of the guide ring 5, which is convenient for operating bolts with different orientations and will not affect the observation of the display screen 4 and the operation of the control panel 10. When encountering nuts with more difficult angles, the slider 17 can be pushed to rotate on the outer wall of the guide ring 5. Since the slider 17 and the torque head 8 are connected by the connecting block 6, the rotation of the slider 17 can drive the torque head 8 to rotate together, thereby achieving the effect of adjusting the angle of the torque head 8. This allows the torque head 8 to better tighten bolts in special positions. The display screen 4 and control panel 10 installed on the outer wall of the wrench body 1 allow the operator to view the torque force and real-time status.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
