Abstract
Description
Technical Field
[0001] This utility model relates to the field of spoke testing technology, and in particular to a device for rapidly measuring spoke length. Background Technology
[0002] Wheel spokes typically consist of a spoke shank, a first spoke cap at one end of the spoke shank, and a second spoke cap at the other end of the spoke shank. The first spoke cap is used to connect with the rim, and the second spoke cap is used to connect with the hub. Because different manufacturers and different models produce spokes of varying lengths, it is necessary to test the spoke length. Current length testing primarily involves direct measurement with a handheld tape measure or a handheld vernier caliper, such as the vernier caliper disclosed in the Chinese invention patent published on November 18, 2009 (publication number CN100561110C). This method requires precise and careful alignment with the spoke caps at both ends of the spoke shank, resulting in a slow testing speed.
[0003] Therefore, a dedicated spoke length testing device with a fast testing speed is needed. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a device for rapidly measuring spoke length, thereby solving the problem of slow spoke testing speed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for quickly measuring spoke length, comprising a main scale and a vernier slidably mounted on the main scale. The main scale has a first clamp, and the vernier has a second clamp corresponding to the first clamp. The first clamp has a first locking groove for placing the spoke rod and limiting the spoke cap, and the second clamp has a second locking groove for placing the spoke rod and limiting the spoke cap. The vernier is also provided with a digital display screen, which is used to display the length value corresponding to the position where the vernier stops on the main scale.
[0006] Preferably, it further includes a measuring platform, a first mounting base, and a second mounting base, wherein the first mounting base is used to fix one end of the main scale on the measuring platform, and the second mounting base is used to fix the other end of the main scale on the measuring platform.
[0007] Preferably, the measuring platform is provided with a first spoke placement slot, which is used to place the spoke to be measured.
[0008] Preferably, the measuring platform is provided with a second spoke placement slot and a third spoke placement slot. The second spoke placement slot is used to place spokes that have passed the measurement, and the third spoke placement slot is used to place spokes that have failed the measurement.
[0009] Preferably, the first locking slot has a first limiting block and a second limiting block installed on the first caliper, and the first limiting block and the second limiting block are spaced apart to form the first locking slot;
[0010] The second locking slot has a third limiting block and a fourth limiting block installed on the second caliper, the third limiting block and the fourth limiting block being spaced apart to form the second locking slot.
[0011] Preferably, the first limiting block is fixedly installed on the first caliper, and the second limiting block is movably installed on the first caliper to adjust the width of the first locking slot;
[0012] The third limiting block is fixedly installed on the second ruler clamp, and the fourth limiting block is movably installed on the second ruler clamp to adjust the width of the second locking slot.
[0013] Preferably, the first caliper is provided with a first adjusting rack corresponding to the second limiting block, and the second limiting block is provided with a first elastic locking member for adapting to the first adjusting rack;
[0014] The second clamp is provided with a second adjusting rack corresponding to the fourth limiting block, and the fourth limiting block is provided with a second elastic locking member for matching the second adjusting rack.
[0015] Preferably, it also includes a pressure sensor, which is signal-connected to the digital display screen to trigger the digital display screen to highlight when the spoke cap is pulled to a specific pressure value.
[0016] Preferably, it also includes a pressure sensor and a speaker, wherein the pressure sensor is mounted on a first locking slot and / or a second locking slot to trigger the speaker to emit an alert sound when the spoke cap is pulled to a specific pressure value.
[0017] Preferably, the speaker and the digital display screen are signal-connected, and the alert tone is the length value displayed on the digital display screen when it is triggered.
[0018] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0019] This invention enables rapid placement of spokes by setting a first and a second locking slot on two calipers. Then, the caliper is slid until the spoke caps at both ends are tightly pressed against and limited outside the locking slots. The digital display screen can display the information in real time, allowing for rapid reading. This enables quick measurement of spoke length.
[0020] Furthermore, by fixing the main scale to the measuring platform, the test platform is more stable, so there is no need to worry about the main scale and vernier swaying under force during measurement, which would affect measurement efficiency. The tester only needs to place the spokes around the measuring platform for testing, making the work simple and convenient. Preferably, the platform is equipped with spoke placement slots, which facilitates the removal of spokes for testing and shortens material transfer time. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.
[0028] like Figures 1-5 As shown, this utility model provides a device for quickly measuring spoke length, including a main scale 1 and a vernier 2 slidably mounted on the main scale 1. The main scale 1 is a long strip-shaped metal substrate with graduation lines marked on its surface. A first clamp 3 is fixedly mounted on one end of the main scale 1. The vernier 2 is slidably mounted on the main scale 1 via a slide rail structure and can move freely along the length direction of the main scale 1. A second clamp 4 is fixedly mounted on the vernier 2, forming a symmetrical structure with the first clamp 3.
[0029] Both the first clamp 3 and the second clamp 4 are provided with locking slots for fixing both ends of the spoke X, so that both ends of the spoke X can be stretched to the position of the spoke cap X2 for testing. Specifically, the first clamp 3 is provided with a first locking slot 5, and the second clamp 4 is provided with a second locking slot 6.
[0030] The vernier 2 is equipped with a digital display screen 7. An integrated grating displacement sensor works in conjunction with the grating main scale 1 on the main scale 1 to detect the position of the vernier 2 in real time. The sensor signal is transmitted to the digital display screen 7, directly displaying the spoke X length value with an accuracy of ±0.01mm.
[0031] By setting a first locking slot 5 and a second locking slot 6 on two calipers, the spoke X can be quickly placed in the first locking slot 5 and the second locking slot 6. Then, the vernier 2 is slid until the spoke caps X2 of both ends of the spoke X are tightly pressed against and limited outside the locking slots. The digital display screen 7 can display in real time and be read quickly, thus realizing the rapid measurement of the length of the spoke X.
[0032] Please refer to Figure 1 and Figure 3 It also includes a measuring platform 8, a first mounting base 9, and a second mounting base 10. The first mounting base 9 is used to fix one end of the main scale 1 onto the measuring platform 8, and the second mounting base 10 is used to fix the other end of the main scale 1 onto the measuring platform 8. By fixing the main scale 1 onto the measuring platform 8, the testing platform is more stable. Therefore, there is no need to worry about the main scale 1 and vernier 2 swinging under force during measurement, which would affect the measurement efficiency. The tester only needs to place the spokes X around the measuring platform 8 for testing, making the work simple and convenient.
[0033] Please refer to Figure 5 In a preferred embodiment, the measuring platform 8 is provided with a first spoke placement slot 11, which is used to place the spoke X to be measured. This facilitates the handling of the spoke X for testing and shortens the material transfer time.
[0034] In other preferred embodiments, the measuring platform 8 is further provided with a second spoke placement slot and a third spoke placement slot. The second spoke placement slot is used to place spokes X that have passed the measurement, and the third spoke placement slot is used to place spokes X that have failed the measurement. This allows spokes X before and after measurement to be placed on the measuring platform 8.
[0035] Please refer to Figure 2 The first slot 5 has a first limiting block 12 and a second limiting block 13 installed on the first caliper 3. The first limiting block 12 and the second limiting block 13 are spaced apart to form the first slot 5.
[0036] The second locking slot 6 has a third limiting block 14 and a fourth limiting block 15 mounted on the second clamp 4. The third limiting block 14 and the fourth limiting block 15 are spaced apart to form the second locking slot 6. This locking slot has a simple structure, is highly practical, and is easy to manufacture.
[0037] Each limiting block can be fixedly installed in the ruler clamp for use with a specific model of spoke X.
[0038] In order to accommodate different types of spokes X, in this embodiment, the first limiting block 12 is fixedly installed on the first caliper 3, and the second limiting block 13 is movably installed on the first caliper 3 to adjust the width of the first locking slot 5; the second limiting block 13 can be flexibly adjusted to move closer to or further away from the first limiting block 12.
[0039] The third limiting block 14 is fixedly installed on the second pliers 4, and the fourth limiting block 15 is movably installed on the second pliers 4 to adjust the width of the second locking slot 6. The fourth limiting block 15 can be flexibly adjusted to move closer to and further away from the third limiting block 14, thereby flexibly adjusting the width of the second locking slot 6.
[0040] Because of the structure that allows for flexible adjustment of the width of the slot, when dealing with spokes of different models X, the width of the slot can be adjusted to accommodate spokes X of different diameters. This allows the spoke rod X1 to be easily placed into the slot and slide freely within it, while the spoke cap X2 is blocked outside the slot, ensuring measurement accuracy.
[0041] There are multiple ways to enable the second limit block 13 and the fourth limit block 15 to be movably mounted on the caliper, such as using a sliding groove on the caliper and a threaded rod and nut on the limit block for fastening and adjustment.
[0042] In a preferred embodiment, the first pliers 3 is provided with a first adjusting rack corresponding to the second limiting block 13, and the second limiting block 13 is provided with a first elastic locking member for adapting to the first adjusting rack; for example, the first elastic locking member (such as a spring buckle) is embedded in the tooth groove of the adjusting rack, and the position of the second limiting block 13 can be adjusted by pressing or moving the elastic locking member.
[0043] The second pliers 4 is provided with a second adjusting rack corresponding to the fourth limiting block 15, and the fourth limiting block 15 is provided with a second elastic locking member for adapting to the second adjusting rack.
[0044] By employing a positioning structure that adapts to both flexible locking components and an adjusting rack, adjustment is simple and can be quickly adapted to different spoke models X.
[0045] In a preferred embodiment, a pressure sensor is also included, which is connected to the digital display screen 7. When the vernier 2 is pulled, the spoke caps X2 at both ends of the spoke rod X1 will eventually be pressed against the outside of the limit block. When the spoke caps X2 are pulled to form a specific pressure value with the limit block, the digital display screen 7 is triggered to highlight the test results.
[0046] The pressure sensor can be installed on the first limit block 12, or another pressure sensor can be installed on the third limit block 14; since the first limit block 12 and the third limit block 14 are fixedly installed on the caliper, the installation of the pressure sensor is simpler.
[0047] In a preferred embodiment, a pressure sensor and a speaker are also included, wherein the pressure sensor is mounted on a first locking slot 5 and / or a second locking slot 6 to trigger the speaker to emit an alert sound when the spoke cap X2 is pulled to a specific pressure value.
[0048] Preferably, the speaker and the digital display screen 7 are signal-connected, and the alert tone is the length value displayed on the digital display screen 7 when triggered. This provides multiple ways to remind users of the test length, avoiding recording errors. In another preferred embodiment, the alert tone can indicate whether the test is passed or failed.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
