Description

Technical Field

[0001] The utility model relates to the technical field of handheld tools, in particular to a high-torque wrench with a shock-absorbing structure. Background Art

[0002] Existing high-torque wrenches have high vibration, which poses a challenge to the stability and life of the contact between the battery pack and the main unit. Traditional wrenches on the market use an integral housing structure, or a shock-absorbing structure is built into the connection between the upper part of the handle switch and the main body. The disadvantage of the integral structure is that the vibration is transmitted to the battery pack, and the contact piece is prone to electrocorrosion. For example, in Chinese patent CN208468215U, Figure 1 The shock-absorbing structure in the device is provided with mounting holes and elastic parts at the connection between the upper part of the handle switch and the body. The disadvantage is that the body and the handle are fixed by screws pressing the rubber pad. Since rubber is an elastomer, it is difficult to accurately control the tightening torque. If the tightening torque is too loose, the machine will swing. If the tightening torque is too tight, the shock-absorbing effect cannot be achieved. Utility Model Content

[0003] The purpose of the utility model is to provide a high torque wrench with a shock-absorbing structure in view of the shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model discloses a technical solution of a high-torque wrench with a shock-absorbing structure, including a machine head, a handle part, and a mounting part, wherein the machine head is arranged above the handle part, the mounting part is movably connected to the handle part, and the mounting part is used to install a battery pack; a spherical mounting groove is provided below the handle part, and an elastomer is provided in the spherical mounting groove; the mounting part has a spherical mounting seat, and the spherical mounting groove is movably connected to the spherical mounting seat.

[0005] Furthermore, a flange portion is provided below the spherical mounting groove, and the flange portion is evenly distributed with three grooves. The spherical mounting seat is provided with a track groove, and a spring piece is provided in the track groove. The flange portion is embedded in the track groove, and the spring piece is engaged in the groove.

[0006] Furthermore, the handle portion includes a left housing and a right housing, wherein a left spherical mounting groove is provided below the left housing, and a right spherical mounting groove is provided below the right housing, and elastomers are provided in the left spherical mounting groove and the right spherical mounting groove, and the elastomers are rubber-coated.

[0007] Furthermore, the mounting part includes a left mounting shell and a right mounting shell, wherein the left mounting shell and the right mounting shell are fixed together, wherein a controller is installed below the left spherical mounting groove and the right spherical mounting groove, and a shockproof column is arranged between the left mounting shell and the left side of the controller.

[0008] Furthermore, the shock-proof column is arranged between the right mounting shell and the right side of the controller.

[0009] Furthermore, the shock-proof column is arranged between the left housing and the upper surface of the controller.

[0010] Furthermore, the shock-proof column is arranged between the right housing and the upper surface of the controller.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The spherical universal joint structure is adopted. The vibration generated by the operation of the large torque wrench is partially absorbed by the shock-absorbing surface of the ball, reducing the impact of vibration on the battery pack.

DETAILED DESCRIPTION

[0022] Example 1

[0023] like Figure 2 and Figure 6As shown, this embodiment of a high-torque wrench with a shock-absorbing structure includes a head portion 10 housing a drive motor. A handle portion extends from below the head portion 10 and is movably connected to a mounting portion 20. The mounting portion 20 has a plug-in terminal interface for inserting a battery pack. High torque is defined as a torque greater than 600N.

[0024] A spherical mounting groove is provided below the handle, into which an elastic body 14 is disposed. The mounting portion 20 has a spherical mounting seat 28, with the spherical mounting groove movably connected to the spherical mounting seat 28. The handle portion includes a left housing 11 and a right housing 12. The mating left and right housings 11 and 12 form the handle portion, which is held by the operator.

[0025] like Figure 3 As shown, a left spherical mounting slot 111 is provided below the left housing 11, and a right spherical mounting slot 121 is provided below the right housing 12. Both left and right spherical mounting slots 111 and 121 contain an elastic body 14, which is encased in a spherical rubber coating. Because the handle and mounting portion 20 utilize a spherical universal joint, the vibration generated by the high-torque wrench's operation is partially absorbed by the spherical, shock-absorbing surface, reducing the impact of this vibration on the battery pack mounted on the mounting portion 20.

[0026] like Figure 4-5 As shown, in order to facilitate use in spaces of different sizes, a flange portion 13 is provided below the spherical mounting groove. The flange portion 13 surrounds the spherical mounting groove in a circle along the circumferential direction. The flange portion 13 is evenly distributed with three grooves 131. The installation positions of the three grooves 131 are respectively 0°, 90°, and 180°. The spherical mounting seat 28 is provided with a track groove 23, and a spring 24 is provided in the track groove 23. The flange portion 13 is embedded in the track groove 23, and the spring 24 is engaged in the groove 131. The flange portion 13 and the track groove 23 are used in conjunction to ensure that the left mounting shell 21 and the right mounting shell 22 can rotate on a fixed plane. By providing the groove 131 and the corresponding biasing mechanism (for example, including the spring 24), the battery pack can be fixed at a plurality of different angles relative to the spring 24. The groove 131 is set to a smooth shape, so that when the user applies a force sufficient to overcome the biasing force of the spring piece 24 (for example, when the user applies a sufficiently large rotational force on the spherical mounting seat 28), the spring piece 24 can be disengaged from the groove 131, allowing the spherical mounting seat 28 to continue to rotate, for example, to another adjacent groove 131, thereby changing the fixed angle of the spherical mounting seat 28 relative to the handle portion.

[0027] The mounting portion 20 includes a left mounting shell 21 and a right mounting shell 22, wherein the left mounting shell 21 and the right mounting shell 22 are fixed together, and a controller 25 is arranged between the left mounting shell 21 and the right mounting shell 22, wherein the controller 25 is installed below the left spherical mounting groove 111 and the right spherical mounting groove 121.

[0028] The shock-proof column is arranged between the right housing and the upper surface of the controller.

[0029] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
