Abstract
Description
Technical Field
[0001] This utility model relates to the field of metrology and testing equipment technology, and in particular to a torque measurement adapter for a bottle cap torque tester. Background Technology
[0002] Existing bottles typically open and close by rotating the cap. Therefore, the cap needs to have a certain tightness to ensure a seal and prevent leakage, especially of liquid substances. Furthermore, users usually separate the cap from the bottle by rotating it. This process requires ease of separation, so the tightness between the cap and bottle should not be too great, as this would make separation difficult. Therefore, the tightness between the cap and bottle needs to be carefully considered.
[0003] Existing methods for adjusting the tightness between bottle caps and bottles typically employ torque measuring devices to measure the torque generated when the cap and bottle rotate apart, thereby calculating the magnitude of the separation force and making corresponding adjustments. However, existing bottle cap torque testers exhibit varying degrees of sensitivity; therefore, there is an urgent need for a device capable of calibrating the sensitivity of bottle cap torque testers. Utility Model Content
[0004] The purpose of this invention is to provide a torque measurement adapter for a bottle cap torque tester to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides a torque measuring adapter for a bottle cap torque tester, comprising an adjusting block and a fixing block. The adjusting block consists of two parts, located on the left and right sides below the fixing block, respectively. Both the fixing block and the adjusting block are provided with threaded holes, and the fixing block and the adjusting block are connected by nuts. The fixing block is provided with a lever arm connecting part, and a lever arm fixing mechanism is provided above the lever arm connecting part.
[0006] Preferably, the lever arm connecting part is located at the center of the fixed block.
[0007] Preferably, the lever arm connecting part is circular.
[0008] Preferably, the lever arm fixing mechanism includes a support frame, the upper part of which is configured as a hollow structure, and a first push plate and a second push plate are provided inside the hollow structure. Both the first push plate and the second push plate are provided with screws passing through the side wall of the support frame, and a fixing column is provided above the first push plate and the second push plate.
[0009] Preferably, the lower part of the support frame is configured with an L-shaped structure, and a circular opening with the same diameter as the lever arm connection is provided near the fixing block.
[0010] Preferably, the first push plate and the second push plate are elastic plates.
[0011] Therefore, the torque measuring adapter for a bottle cap torque tester with the above-described structure of this utility model has the following beneficial effects:
[0012] (1) Adjust the lower adjustment block to make the adapter position in the center of the bottle cap torque tester, connect the lever arm to the lever arm connection part, and hang the force value weight on the lever arm to obtain the torque value, thereby completing the calibration of the bottle cap torque tester;

[0021] Example
[0022] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.
[0023] like Figure 1-2 As shown, this utility model discloses a torque measuring adapter for a bottle cap torque tester, employing the aforementioned structure. It includes an adjusting block 2 and a fixing block 1. Two adjusting blocks 2 are provided, located on the left and right sides below the fixing block 1, respectively. Both the fixing block 1 and the adjusting block 2 have threaded holes and are connected by nuts. The fixing block 1 has a lever arm connecting part 3, and a lever arm fixing mechanism is provided above the lever arm connecting part 3. The threaded holes on the fixing block 1 and the adjusting block 2 correspond, and the fixing block 1 and the adjusting block 2 are assembled together using nuts.
[0024] The lever arm connecting part 3 is located at the center of the fixed block 1. The lever arm connecting part 3 is circular.
[0025] The lever arm fixing mechanism includes a support frame 4, with a hollow structure on top of the support frame 4. Inside the hollow structure are a first push plate 5 and a second push plate 6. Both the first push plate 5 and the second push plate 6 have screws 7 passing through the side walls of the support frame 4. A fixing post 8 is located above each of the first push plate 5 and the second push plate 6. Two fixing posts 8 are provided on each of the first push plate 5 and the second push plate 6, and four openings are provided on each of the first push plate 5 and the second push plate 6 for adjusting the position of the fixing posts 8. The first push plate 5 and the second push plate 6 are elastic plates. The lever arm is firmly fixed by the first push plate 5, the second push plate 6, and the fixing posts 8, preventing it from wobbling. This structure can fix lever arms of different shapes. The width of the first push plate 5 and the second push plate 6 is smaller than the width of the hollow structure.
[0026] The lower part of the support frame 4 is designed with an L-shape, and a circular opening 9 with the same diameter as the lever arm connecting part 3 is provided near the fixing block 1. The circular opening 9 is connected to the lever arm connecting part 3 to facilitate the passage of the lever arm.
[0027] In use, move the first push plate 5 and the second push plate 6 in opposite directions until they can accommodate the lever arm, then move them in opposite directions until the fixing post 8 fixes the lever arm. A force-value weight is hung on the lever arm. When using a lever arm of known length and a force-value weight of known value, the torque value can be obtained.
[0028] Therefore, the present invention provides a torque measuring adapter for a bottle cap torque tester with the above-mentioned structure, which is suitable for lever arms of different shapes, convenient to use and accurate in measurement.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
