Description

Technical Field

[0001] This utility model relates to the field of torque wrench technology, and in particular to a manual torque wrench head with reversible force application. Background Technology

[0002] Existing one-way ratchet torque wrenches typically have only one square tenon in the wrench head. When actually tightening bolts, they can only be tightened in one direction and cannot be used to change direction to apply force. This makes it impossible to tighten bolts with different directions of rotation or to install and remove the same bolt.

[0003] In response to the above situation, existing technologies have developed wrench heads with two square tenons, such as the solution disclosed in the utility model patent with authorization announcement number CN208084230U. Although the above solution can be turned in two directions, when installing and removing the same bolt, it is necessary to switch between the two square tenons. That is, first connect the adapter sleeve on square tenon A to the bolt to complete the bolt installation, then separate the adapter sleeve on square tenon A from the bolt, and then put the adapter sleeve on square tenon B on the outside of the bolt to remove the bolt. This is too cumbersome.

[0004] Therefore, it is necessary to invent a manual torque wrench head that can reverse the direction of force application to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a manual torque wrench head with reversible force application, which can drive the bolt in two directions without separating the adapter sleeve from the bolt, effectively simplifying the operation steps and making it more convenient to use. This solves the problem of the existing solution mentioned in the background art, which requires switching between two square tenons when installing and removing the same bolt. That is, first connecting the adapter sleeve on square tenon A to the bolt to complete the bolt installation, then separating the adapter sleeve on square tenon A from the bolt, and then fitting the adapter sleeve on square tenon B onto the outside of the bolt to achieve bolt removal, which is too cumbersome.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a reversible torque wrench head, comprising:

[0007] A connecting component, which provides a mounting base for the screwing component and the adjustable locking component;

[0008] The screwing assembly, wherein the adjustable locking assembly is used to rotate the bolt after connecting the adapter sleeve; and

[0009] An adjustable locking assembly includes a fixed shaft nested at the bottom of the housing cavity and a rotating shaft nested at the bottom of the housing cavity via bearings. The rotating shaft is located between the transmission shaft and the fixed shaft. Two movable sleeves are rotatably sleeved on the outside of the fixed shaft along the vertical direction via bearings. A pawl plate is fixedly connected to the outside of each of the two movable sleeves. A return spring is fixedly connected to the side of each of the two pawl plates away from the ratchet. Both return springs are fixedly connected to the inner wall of the housing. An eccentric sleeve is fixedly sleeved on the outside of the rotating shaft. The left pawl plate is pushed away by the eccentric sleeve, and the right pawl plate locks the ratchet. An adjustment knob is fixedly sleeved at the top of the outside of the rotating shaft. A moving magnet that is magnetically attracted to the fixed magnet B is nested to the left of the adjustment knob.

[0010] According to at least one embodiment of the present disclosure, a reversible torque wrench head includes a housing with a top cover fixedly disposed on the top of the housing.

[0011] According to at least one embodiment of the present disclosure, a reversible torque wrench head has a connecting block fixedly connected to the end of the housing, and a connecting screw hole is provided at the end of the connecting block away from the housing.

[0012] According to at least one embodiment of the present disclosure, a reversible torque wrench head has two clearance holes on the top of the top cover, and the fixed shaft and the rotating shaft are rotatably disposed inside the adjacent clearance holes via bearings.

[0013] According to at least one embodiment of the present disclosure, a reversible torque wrench head includes a drive shaft rotatably nested inside a housing via a bearing, and a top cover rotatably sleeved on the top of the drive shaft via a bearing.

[0014] According to at least one embodiment of the present disclosure, a reversible torque wrench head is provided with a ratchet fixedly sleeved on the outer side of the drive shaft, and a square tenon is fixedly connected to the top end of the drive shaft.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features an adjustable locking component. When the moving magnet and the fixed magnet B are magnetically attracted to each other, the eccentric sleeve pushes the left ratchet plate, causing its end to move away from the ratchet wheel. The right ratchet plate then engages with the ratchet wheel to form a ratchet-pawl transmission structure. This allows the drive shaft to drive the adapter sleeve on the square tenon in one direction. To adjust the driving direction, the adjustment knob is rotated, causing the moving magnet and the fixed magnet A to magnetically attract each other. During this process, the rotating shaft moves the eccentric sleeve away from the left ratchet plate and pushes the right ratchet plate. The left ratchet plate, under the push of the left return spring, forms a ratchet-pawl transmission structure with the ratchet wheel, while the right ratchet plate moves away from the ratchet wheel. The drive shaft can then drive the bolt in the other direction via the adapter sleeve on the square tenon. Compared to existing technologies, this invention allows for two-way bolt driving without separating the adapter sleeve from the bolt, effectively simplifying operation and making it more convenient to use.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a reversible torque wrench head according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the connecting assembly 1 and the tightening assembly 2 of a reversible torque wrench head according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the adjustable locking assembly 3 of a manual torque wrench head with reversible force application according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the reversible torque wrench head disclosed herein may include components such as a connecting assembly 1, a turning assembly 2, and an adjustable locking assembly 3.

[0030] like Figure 2 As shown in this disclosure, the connecting assembly 1 includes a housing 11, a top cover 12 is fixedly disposed on the top of the housing 11, a connecting block 13 is fixedly connected to the end of the housing 11, a connecting screw hole 14 is provided at the end of the connecting block 13 away from the housing 11, two clearance holes are provided on the top of the top cover 12, and the fixed shaft 31 and the rotating shaft 32 are both rotatably disposed inside the adjacent clearance holes through bearings.

[0031] This allows the wrench lever to be inserted into the connecting screw hole 14 and tightened, thereby completing the connection between the wrench lever and the connecting block 13.

[0032] like Figure 2As shown, in a preferred embodiment, the screwing assembly 2 includes a drive shaft 21 that is rotatably nested inside the housing 11 via a bearing, a top cover 12 that is rotatably sleeved on the top of the drive shaft 21, a ratchet 22 that is fixedly sleeved on the outside of the drive shaft 21, and a square tenon 23 that is fixedly connected to the top of the drive shaft 21.

[0033] Thus, after the ratchet 22 is blocked and locked by the adjacent pawl plate 34, the force applied to the ratchet 22 is transmitted through the drive shaft 21 and the tenon 23 to the adapter sleeve on the outside of the tenon 23. Then the adapter sleeve drives the bolt to rotate. Depending on the different pawl plates 34 that lock the ratchet 22, the adapter sleeve can drive the bolt to rotate in two directions.

[0034] like Figure 3 As shown in this disclosure, the adjustable locking assembly 3 includes a fixed shaft 31 fixedly nested at the bottom of the inner cavity of the housing 11 and a rotating shaft 32 rotatably nested at the bottom of the inner cavity of the housing 11 via bearings. The rotating shaft 32 is located between the transmission shaft 21 and the fixed shaft 31. Two movable sleeves 33 are rotatably sleeved on the outside of the fixed shaft 31 along the vertical direction via bearings. A pawl plate 34 is fixedly connected to the outside of each of the two movable sleeves 33. A return spring 35 is fixedly connected to the side of each of the two pawl plates 34 away from the ratchet 22. Both return springs 35 are fixedly connected to the inner wall of the housing 11. An eccentric sleeve 36 is fixedly sleeved on the outside of the rotating shaft 32. The left pawl plate 34 is pushed away by the eccentric sleeve 36, and the right pawl plate 34 locks the ratchet 22. An adjustment knob 37 is fixedly sleeved on the top of the outside of the rotating shaft 32. A moving magnet 38 that is magnetically attracted to the fixed magnet B16 is nested on the left side of the adjustment knob 37.

[0035] Therefore, when the moving magnet 38 and the fixed magnet B16 are magnetically attracted to each other, the eccentric sleeve 36 pushes the left ratchet plate 34, causing the end of the left ratchet plate 34 to move away from the ratchet wheel 22. At this time, the right ratchet plate 34 cooperates with the ratchet wheel 22 to form a ratchet-pawl transmission structure. This can then drive the adapter sleeve on the square tenon 23 in one direction through the transmission shaft 21. When it is necessary to adjust the driving direction, the adjustment knob 37 is rotated, causing the adjustment knob 37 to drive the moving magnet 38 and the fixed magnet A15 to magnetically attract each other. In this process... In this process, the rotating shaft 32 drives the eccentric sleeve 36 away from the left ratchet plate 34 and pushes the right ratchet plate 34. At this time, the left ratchet plate 34 forms a ratchet-pawl transmission structure with the ratchet wheel 22 under the push of the left return spring 35, while the right ratchet plate 34 moves away from the ratchet wheel 22. At this time, the transmission shaft 21 can be driven in another direction through the adapter sleeve on the square tenon 23. Compared with the prior art, the bolt can be driven in two directions without separating the adapter sleeve from the bolt, which effectively simplifies the operation steps and makes it more convenient to use.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
