Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0027] like Figures 1 to 4As shown in the figure, an embodiment of the present invention relates to a torque test fixture for a lens barrel nut, comprising a test stand 10, a rotating assembly 20, a clamping assembly 30, and a torque tester 31; the test stand 10 comprises a vertical plate 11 and a horizontal plate 12, the top of the vertical plate 11 is connected to the bottom of the horizontal plate 12, and the bottom of the vertical plate 11 is connected to the clamping assembly 30; the rotating assembly 20 is movably connected to the horizontal plate 12, and the rotating assembly 20 comprises a toggle member 40, a rotating rod 21, an adjusting member 31, and a torque tester 31. The adjusting sleeve 50 and the plug-in block 22 are connected to the toggle member 40 and the rotating rod 21; the adjusting sleeve 50 is slidably connected to the rotating rod 21; the plug-in block 22 is inserted under the adjusting sleeve 50; the clamping assembly 30 includes a base plate 32 and a clamping seat 60; one side of the base plate 32 is connected to the bottom of the vertical plate 11; the clamping seat 60 is arranged above the base plate 32; the torque tester 31 is connected to the clamping seat 60 and is arranged below the rotating assembly 20.

[0028] Furthermore, a bearing 13 is connected above the horizontal plate 12, and the rotating rod 21 is rotatably connected to the bearing 13. Specifically, the rotating rod 21 rotates relative to the bearing 13, so that the operator can rotate the object to be tested, thereby improving the test accuracy.

[0029] Furthermore, the toggle member 40 includes a grip portion 41 and a mounting portion 42. The grip portion 41 is connected to one side of the mounting portion 42, which is connected to the upper portion of the rotating rod 21. Specifically, toggling the grip portion 41 drives the mounting portion 42, causing the rotating rod 21 to rotate, effectively improving the convenience of testing and thereby enhancing test accuracy.

[0030] Furthermore, the adjustment sleeve 50 includes an upper sleeve 51 and a lower sleeve 52. The upper sleeve 51 has a mounting slot 53 disposed therein, to which the lower portion of the rotating rod 21 is connected. The lower sleeve 52 is connected below the upper sleeve 51. Limiting slots 54 are provided on either side of the mounting slot 53, each of which is connected to a limiting screw 55, which passes through the limiting slots 54 and is connected to the rotating rod 21. Specifically, the upper sleeve 51 is movably connected to the rotating rod 21. The height of the upper sleeve 51 can be adjusted according to the size of the object to be tested to meet the testing requirements of the object to be tested. The limiting screw 55 not only connects the rotating rod 21 to the upper sleeve 51, but also allows the limiting screw 55 to move within the limiting slot 54 to limit the upper sleeve 51, thereby improving ease of use.

[0031] Furthermore, a connecting column 56 is provided below the upper sleeve 51, and the connecting column 56 is plugged into the lower sleeve 52 via a mounting screw 57. Specifically, the connecting column 56 and the mounting screw 57 ensure that the upper sleeve 51 and the lower sleeve 52 are stably connected, thereby ensuring the stability of the test.

[0032] Furthermore, the plug-in block 22 is installed below the lower casing 52 by means of a plug-in screw 23. Specifically, the plug-in block 22 is stably connected to the lower casing 52 by means of the plug-in screw 23, thereby ensuring the stability of the test.

[0033] Furthermore, a mounting plate 33 is provided above the base plate 32, and the mounting plate 33 is provided below the clamping seat 60. Specifically, the mounting plate 33 is provided to effectively increase the height of the clamping seat 60 and improve the stability of the clamping seat 60, which is highly practical.

[0034] Furthermore, the clamping base 60 has a clamping groove 61 formed inside, which is connected to the torque tester 31. The outer side of the clamping base 60 has a plurality of fixing holes 62 formed therein, into which fixing screws 63 are inserted, which are connected to the torque tester 31. Specifically, the clamping base 60 is a circular clamping base 60; the torque tester 31 is placed in the clamping groove 61 of the clamping base 60 and is locked by the fixing screws 63, preventing the torque tester 31 from shaking during use and affecting the test results, effectively improving test accuracy.

[0035] The utility model is provided with a test stand 10, a rotating assembly 20, a clamping assembly 30, and a torque tester 31. The torque tester 31 is first placed in a clamping seat 60 for fixing, and then the object to be tested is placed on the torque tester 31. The adjusting sleeve 50 in the rotating assembly 20 is adjusted to connect the plug-in block 22 to the object to be tested. The toggle member 40 is rotated to drive the rotating rod 21 to rotate, and then drive the plug-in block 22 to rotate, thereby realizing the torque test of the object to be tested, and obtaining the torque value through the torque tester 31, thereby avoiding the problem of low test accuracy due to the operator's testing level when manually testing the torque value. The device has a simple structure, low cost, and easy operation, and is suitable for large-scale popularization and promotion.

[0036] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
