[0005] The noise mechanism according to the invention according to one embodiment is accommodated in a housing of a torque wrench and arranged such that a linkage of the torque wrench is inserted through the noise mechanism. The noise mechanism comprises a first loaded element and a second loaded element. The first loaded element is pivotally mounted in the housing, wherein a first hole is arranged on the first loaded element, which runs in the axial direction of the first loaded element and is provided for receiving the linkage, wherein the first hole is provided with a deviation channel that runs in the radial direction of the first hole. The second loaded element is slidably mounted in the housing. The first and second loaded elements support one another.A second hole is arranged on the second loaded element, corresponding to the axial direction of the first hole of the first loaded element, and is intended to accommodate the rod assembly. The force applied to the first loaded element is greater than the force applied to the second loaded element. The first loaded element pivots under force and, in doing so, deflects the rod assembly via the deflection channel, creating a deflection angle on the second loaded element when the first loaded element is displaced.

[0006] The noise mechanism according to the invention according to one embodiment comprises a first loaded element and a second loaded element. A first hole is arranged on the first loaded element, which runs in the axial direction of the first loaded element and is provided for receiving the rod assembly, wherein the first hole is provided with a deflection channel that runs in the radial direction of the first hole.

Detailed description of preferred embodiments

[0008] Objects, features, and advantages of the present invention will be explained in more detail below with reference to the detailed description of exemplary embodiments and the accompanying drawings. However, the invention is not limited to the description of these exemplary embodiments and their illustration in the accompanying drawings.

[0009] As in Fig. 1 to Fig. As shown in Figure 8, the noise mechanism 10 according to the invention is housed in a housing 21 of a torque wrench 20 and arranged such that a rod 22 housed in the housing 21 is inserted through the noise mechanism 10. The torque wrench 20 can be a driven torque wrench, wherein the housing 21 can be a hollow cylinder and the rod 22 can be a cylinder.

[0010] As in Fig. 2 and Fig. 4 to Fig. As shown in Figure 7, the noise mechanism 10 comprises a first loaded element 11 and a second loaded element 12.

[0011] As in Fig. 2, Fig. 4, Fig. 5 and Fig. 7, the loaded element 11 can be a hollow cylinder. A first hole 111 is arranged on the first loaded element 11, which runs in the axial direction of the first loaded element 11 and is provided for receiving the rod 22. A deviation channel 111A is arranged on the hole 111, which runs in the radial direction of the first hole 111 and has a length 111B in its extension direction, which is the greatest distance between two opposite side walls in the extension direction. The first loaded element 11 is pivotally mounted in the housing 21 and connected at one end to a ratchet assembly 24. As shown in Fig. 1 and Fig. 4 to Fig. As shown in Figure 6, the ratchet assembly 24 is mounted on the opening of one end of the first loaded member 11, located outside the housing 21. The ratchet assembly 24 includes a pivot member 242 and a drive member 241, with the pivot member 242 pivotally mounted on the first loaded member 11 and the drive member 241 rotatably mounted on the pivot member 242.

[0012] As in Fig. 2 and Fig. 4 to Fig. As shown in Figure 6, the linkage 22 is rotatably mounted in the housing 21 such that one end of the linkage 22 is eccentrically rotatably mounted on the pivot member 242, while the other end of the linkage 22 is driven by a drive power source (e.g., a pneumatic or electric drive power source) and thus caused to rotate. The pivot member 242 is pivoted with the eccentric rotational movement of the linkage 22, and the drive member 241 rotates clockwise or counterclockwise with the pivotal movement of the pivot member 242.

[0013] As in Fig. 2, Fig. 4, Fig. 5 and Fig. 7, the other end of the first loaded element 11 rests on one end of the second loaded element 12. Preferably, the deflection channel 111A of the first loaded element 11 is arranged in the first hole 111, at which the first loaded element 11 and the second loaded element 12 rest against each other. The second loaded element 12 can be a hollow cylinder. A second hole 121 is arranged on the second loaded element 12 corresponding to the axial direction of the first hole 111 of the first loaded element 11 and is provided for receiving the rod assembly 22. The second loaded element 12 is slidably mounted in the housing 21 and is connected at its other end to a torque assembly 25.

[0014] As in Fig. 1 to Fig. 4 and Fig. As shown in Figure 7, the torque assembly 25 is mounted at the opening of the other end of the second loaded member 12. By axially displacing the torque assembly 25 within the housing 21, the force applied to the second loaded member 12 can be adjusted. The torque assembly 25 comprises a torque element 251 and an adjustment element 252 connected to the torque element 251, wherein the torque element 251 may be a torsion spring. The torque element 251 is received in the housing 21 and pulled over the second loaded member 12. The linkage 22 is inserted through the torque element 251. The adjustment element 252 is slidably mounted on the housing 21. The torque element 251 is elastically supported on the second loaded member 12 and the adjustment element 252.The adjustment element 252 is rotated and then axially displaced to adjust the force exerted by the torque element 251 on the second loaded element 12.

[0015] When the ratchet assembly 24 exerts a force on the first loaded element 11, the first loaded element 11 is pivoted on the housing 21. When the ratchet assembly 24 exerts a force on the second loaded element 12, the second loaded element 12 is axially displaced on the housing 21. If the force applied to the first loaded element 11 is greater than the force applied to the second loaded element 12, the first loaded element 11 is pivoted under force, creating a deflection angle when the first loaded element 11 is displaced on the second loaded element 12. A sound is generated to signal that the preset torque value has been reached. Fig. 7b it can be seen that the deviation angle arises when the axial line of the pivoted first loaded element 11 and the axial line of the second loaded element 12 cross each other.

[0016] As in Fig. As shown in Figure 6, the pivoted first loaded element 11 deflects the rod 22 with the deflection channel 111A of the first hole 111 to prevent the first loaded element 11 from being pivoted due to its contact with the rod 22 and thereby impacting the housing 21. This prevents the generation of noise. In this way, the first loaded element 11 smoothly deflects the rod 22 under force loading, whereby unhindered transmission of the driving force and acoustic signaling can be realized simultaneously.

[0017] As in Fig. 2 and Fig. 4 to Fig. As shown in Figure 7, a contact element 13 is further arranged between the first and second loaded elements 11, 12, which bear against one another. If the force applied to the first loaded element 11 is greater than the force applied to the second loaded element 12, the first loaded element 11 is pivoted under force to rotate the contact element 13, causing the contact element 13 to slide on the second loaded element 12. Here, the contact element 13 is rectangular, for example.

[0018] The first loaded element 11 is pivotally mounted on the housing 21 by a rotary joint. In one embodiment of the rotary joint, two first screws S1 (see Fig. 1 to Fig. 5) and arranged such that the two first screws S1 are each inserted with their opposite front ends through the side walls of the housing 21 and thus screwed to the side walls of the first loaded element 11. The front ends of the two first screws S1 are pivoted with the first loaded element 11, whereby the rear ends of the two first screws S1 on the housing 21 are rotated. A ring 23 is mounted between the side walls of the housing 21 and the rear ends of the two first screws S1, which ensures that the two first screws S1 on the housing 21 can be rotated more freely.

[0019] As in Fig. 2 and Fig. 4 to Fig. 7, a first ring part 112 is further arranged on the first loaded element 11 between the first loaded element 11 and the contact element 13, wherein the first ring part 112 is formed, for example, in the shape of a hollow cylinder. The first hole 111 of the first loaded element 11 extends to the first ring part 112 and serves to receive the rod assembly 22. The deflection channel 111A is arranged on the first ring part 112. The first ring part 112 is detachably mounted on the opening of the other end of the first loaded element 11. At the two axial ends of the first ring part 112, a first front portion 1121 with a reduced diameter and a first rear portion 1122 with an enlarged diameter are formed respectively. Alternatively, the first ring part 112 may be formed integrally at the opening of the other end of the first loaded member 11 and is thus not limited to the above-mentioned detachable arrangement.

[0020] The first front portion 1121 of the first ring part 112 is detachably mounted on the opening of the other end of the first loaded element 11 by inserting the first front portion 1121 of the first ring part 112 into the opening of the other end of the first loaded element 11 and further screwing two second screws S2 in opposite directions to the two opposite side walls of the first loaded element 11 and the two opposite side walls of the first front portion 1121.

[0021] On the front side of the first rear portion 1122 of the first ring part 112, a first limiting groove 1123 is formed, which is widened from its bottom toward its opening so that two inclined walls are formed symmetrically to each other, wherein the two inclined walls are arranged in the extension direction of the first limiting groove 1123. Here, the extension direction of the first limiting groove 1123 and the extension direction of the deviation channel 111A do not cross each other. The first limiting groove 1123 is almost trapezoidal (as in this form ), wherein the number of first limiting grooves 1123 is at least one, preferably two. If two first limiting grooves 1123 are provided, they are arranged at a distance from one another on the end face of the first rear section 1122. If only one first limiting groove 1123 is provided, it is arranged next to the deviation channel 111A, specifically parallel to the same. If two first limiting grooves 1123 are provided, they are arranged on either side of the deviation channel 111A, specifically parallel to the same.

[0022] As in Fig. 2, Fig. 4, Fig. 5 and Fig. 7, a second ring part 122 is further arranged on the second loaded element 12 between the second loaded element 12 and the contact element 13, wherein the second ring part 122 is formed, for example, in the shape of a hollow cylinder. The second hole 121 of the second loaded element 12 extends to the second ring part 122 and serves to receive the rod assembly 22. The second ring part 122 is detachably mounted on the opening of one end of the second loaded element 12. A second front portion 1221 with a reduced diameter and a second rear portion 1222 with an enlarged diameter are formed at each of the two axial ends of the second ring part 122. Alternatively, the second ring part 122 can be formed in one piece at the opening of the other end of the second loaded element 121 and is therefore not limited to the above-mentioned detachable arrangement.

[0023] The second front portion 1221 of the second ring part 122 is detachably mounted on the opening of one end of the second loaded element 12 by inserting the second front portion 1221 of the second ring part 122 into the opening of said end of the second loaded element 12 and further screwing two third screws S3 in opposite directions to the two opposite side walls of the second loaded element 12 and the two opposite side walls of the second front portion 1221.The two third screws S3 can also first be screwed into the two opposite side walls of the housing 21 and further guided through the two opposite side walls of the second loaded element 12 and the two opposite side walls of the second front section 1221 and screwed thereto, wherein at a point on the second loaded element 12 and a point on the second ring part 122, at which points the second loaded element 12 and the second ring part 122 are screwed together, a displacement path 123 is arranged which runs axially and is provided to limit the direction of displacement.

[0024] On the end face of the second rear portion 1222 of the second ring part 122, a second limiting groove 1223 is formed corresponding to the first limiting groove 1123 of the first ring part 112, wherein the second limiting groove 1223 is provided for receiving the contact element 13. The two opposite side walls of the contact element 13 are supported on the first limiting groove 1123 and the second limiting groove 1223, respectively. The second limiting groove 1223 is widened from its bottom toward its opening such that two oblique walls are formed symmetrically to one another, wherein the two oblique walls are arranged in the extension direction of the second limiting groove 1223. The second limiting groove 1223 is almost trapezoidal (as in this form ), wherein the number of second limiting grooves 1223 is at least one, preferably two. If two second limiting grooves 1223 are provided, they are arranged at a distance from one another on the end face of the second rear section 1222. If one second limiting groove 1223 is provided, it is arranged next to the second hole 121, specifically parallel to the latter. If two second limiting grooves 1223 are provided, they are arranged on either side of the second hole 121, specifically parallel to the latter.

[0025] The following describes how the contact element 13 moves with the first loaded element 11 on the second loaded element 12.

[0026] It will be Fig. 7a. If the force with which the first loaded element 11 is loaded is smaller than the force with which the second loaded element 12 is loaded, the first loaded element 11 is not pivoted, with the two side walls of the contact element 13 being supported on the bottom of the first limiting groove 1123 of the first loaded element 11 and the bottom of the second limiting groove 1223 of the second loaded element 12.

[0027] It will continue on Fig. 7b. If the force with which the first loaded element 11 is loaded is greater than the force with which the second loaded element 12 is loaded, the first loaded element 11 is pivoted, so that the contact element 13 rotates with the pivoting movement such that the two side walls of the contact element 13 are each supported on the one inclined wall of the first limiting groove 1123 of the first loaded element 11 and on the one inclined wall of the second limiting groove 1223 of the second loaded element 12. When the first loaded element 11 is pivoted, it impacts the housing 21 in such a way that a noise is generated. The more pronounced the impact, the clearer and more perceptible the acoustic signaling becomes. In order for the user to clearly hear the noise and to detect when the preset torque value has been reached, the deflection channel 111A of the first hole 111 of the first loaded element 11 must deflect from the rod 22.It is also conceivable to design the noise mechanism in such a way that the pivoting circumference of the first loaded element 11 is large enough for the first loaded element 11 or the first ring part 112 of the first loaded element 11 to be supported on the inner wall of the housing 21 in order to generate a noise.

[0028] The length 111B of the deflection channel 111A represents one of the key factors for the pivoting capability of the first loaded element 11. The greater the length 111B of the deflection channel 111A, the greater the pivoting space available for the first loaded element 11 to deflect the linkage 22. This means that if the force applied to the first loaded element 11 is greater than the force applied to the second loaded element 12, the first loaded element 11 will pivot, thereby impacting the housing 21 and generating a noise. By appropriately designing the length 111B, it can be ensured that the first loaded element 11 pivots unhindered when the preset torque value is reached, generating a clear and audible acoustic signal.Furthermore, the design of the length 111B has a direct impact on the sensitivity and reliability of the entire noise mechanism.

[0029] In Fig. 8 shows a further embodiment of the contact element 13. Here, the contact element 13 can be connected to the second ring part 122 (see Fig. 8) or the first ring part 112 (not shown) by welding, casting, gluing or fusing, whereby the connection method is not limited to the above-mentioned. If the contact element 13 and the second ring part 122 are to be welded together in one piece (see Fig. 8), the contact element 13 is welded to the original position of the second limiting groove 1223 of the second ring part 122 in such a way that the contact element 13 protrudes from the surface of the second ring part 122. Now, the second limiting groove 1223 is replaced and omitted. In this embodiment, the contact element 13 is formed as a curved structure with a curvature, and the first limiting groove 1123 is recessed to match the curvature of the contact element 13 in terms of profile. Thus, the contact element 13 and the first limiting groove 1123 are formed to almost match each other in terms of profile. The opening of the first limiting groove 1123 is widened so that two symmetrical inclined walls are formed which guide the contact element 13 when it is released from the first limiting groove 1123, so that the contact element 13 can be easily released from the first limiting groove 1123.By loading the first loaded element 11 with a force exceeding the preset torque value and thereby pivoting it, it is ensured that the first loaded element 11 effectively impacts the housing 21 to generate an expected noise.

[0030] The number of contact elements 13 corresponds to the number of the first limiting groove 1123. If the contact element 13 and the second ring part 122 are formed in one piece, the number of contact elements 13 is, for example, one (see Fig. 8), preferably with two. If two contact elements 13 are provided, they are arranged at a distance from one another on the end face of the second rear section 1222 of the second ring part 122. If only one contact element 13 is provided, it is arranged next to the second hole 121, and in particular parallel to the same. If two contact elements 13 are provided, they are arranged on either side of the second hole 121, and in particular parallel to the same. This configuration ensures that the contact element 13 can be precisely aligned with the first limiting groove 1123. When the first loaded element 11 is pivoted, as shown in Fig. As shown in Figure 8, when the first loaded member 11 and the contact element 13 abut or detach from each other, the contact element 13 can then be stably supported and guided. This contributes to the first loaded member 11 effectively impacting the housing 21, thereby generating an expected noise.

[0031] The first limiting groove 1123 is arranged on the end face of the first rear section 1122 of the first ring part 112, with the number of first limiting grooves 1123 being at least one, preferably two. If two first limiting grooves 1123 are provided, they are arranged at a distance from one another on the end face of the first rear section 1122. If only one first limiting groove 1123 is provided, it is arranged next to the first hole 111 and parallel to it. If two first limiting grooves 1123 are provided, they are arranged on either side of the first hole 111 and parallel to it.

[0032] Fig.8 shows a schematic representation of a pivoting movement of the above-mentioned further embodiment of the contact element 13 of the torque wrench 20 with a noise mechanism 10 according to the invention. If the force with which the first loaded element 11 is loaded is smaller than the force with which the second loaded element 12 is loaded, the projecting wall surface of the contact element 13 will bear against the recessed wall surface of the first limiting groove 1123. If the force with which the first loaded element 11 is loaded is greater than the force with which the second loaded element 12 is loaded, the first loaded element 11 will pivot. Since the contact element 13 and the second ring part 122 are formed as one piece, the contact element 13 will detach from the first limiting groove 1123 with the pivoting movement of the first loaded element 11 when the first loaded element 11 is pivoted.In this process, the pivoting movement of the first loaded element 11 is guided and promoted by the release of the contact element 13 from the second ring part 122 so that the first loaded element 11 can effectively impact the housing 21 to generate a noise and thus acoustically signal the achievement of the preset torque value.

[0033] Likewise, the contact element 13 can also be integrally formed with the second ring part 122 by welding, casting, bonding, or fusing, whereby the connection method is not limited to the above. In this case, the first limiting groove 1123 is omitted, and the second limiting groove 1223 is retained accordingly. The operating principle is the same as above, but the structural positions are reversed.

[0034] It should be noted that the terms "first," "second," and "third" in the present invention serve to differentiate and do not imply a sequence. Furthermore, the terms "axial" and "radial" in the present invention serve only for schematic representation, whereby the direction of extension of the respective components is not limited to the axial and radial directions.

[0035] The above-mentioned designs of the exemplary embodiments provide a powered torque wrench that acoustically signals the achievement of the preset torque value. The sound mechanism according to the invention is advantageous in that it precisely signals the achievement of the preset torque value during power transmission, thus ensuring the compatibility of the power drive and acoustic signaling.

[0036] Although the present invention has been described in detail using exemplary embodiments, it will be understood by those skilled in the art that the invention is not limited to these exemplary embodiments. Rather, modifications are possible such that individual features can be omitted or other combinations of features can be implemented, as long as the scope of the appended claims is not exceeded. The disclosure of the present invention includes all combinations of the individual features presented.
