Description

Technical Field

[0001] This utility model relates to the technical field of testing instruments, and in particular to a wire diameter testing instrument. Background Technology

[0002] Automotive interior designers often create leather interiors with decorative stitching, such as dashboard trim. However, due to the complex structure of automotive interior components, decorative stitching is needed to connect the gaps in the leather. This requires measuring the wire diameter of the decorative stitching, necessitating the use of a wire diameter measuring instrument. Existing equipment requires fixing a slide block, securing the decorative stitching to the slide block, connecting the other end to a weight, and then pulling the stitching taut before using the measuring instrument to check the wire diameter.

[0003] However, existing methods of fixing the slide block involve directly inserting bolts into the slide block and squeezing the slide rod, relying on friction for fixation. This method causes deformation of the slide rod, affecting the sliding of the slide block. Therefore, a fixing structure was designed to address the aforementioned problem without affecting the sliding of the slide block. Utility Model Content

[0004] The purpose of this invention is to provide a wire diameter tester to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A wire diameter tester includes: a slide block disposed on the top of the tester body; a positioning assembly disposed on the bottom of the slide block, the positioning assembly including: a threaded rod rotatably disposed on the bottom of the slide block; a worm gear fixedly sleeved on the outer side wall of the top end of the threaded rod; a threaded sleeve sleeved on the outer side wall of the threaded rod and threadedly connected to the threaded rod; a slider fixedly disposed on the outer side wall of the top end of the slider; a vertical rod end passing through the slider and fixedly connected to the slide block; a worm gear with one end passing through the slide block and rotatably connected to the slide block, and the other end meshing with the worm gear.

[0007] In some embodiments, the positioning component further includes a torque disposed at one end of the worm gear.

[0008] In some embodiments, the positioning component further includes a baffle disposed at the bottom end of the upright.

[0009] In some embodiments, the positioning component further includes a rubber sleeve fitted onto the bottom end of the threaded sleeve.

[0010] In some embodiments, the positioning component further includes a bump disposed on the top of the detector body.

[0011] In some embodiments, a connecting assembly is provided on the outer side wall of the upright, the connecting assembly further comprising: a positioning hole formed on the outer side wall of the rubber sleeve; a rotating rod rotatably disposed on the outer side wall of the upright; both ends of the spring being connected to the upright and the rotating rod by means of retaining rings; and an insert block disposed at one end of the rotating rod.

[0012] In some embodiments, the connecting component further includes a cone disposed at one end of the insert.

[0013] In some embodiments, two sets of the connecting components are symmetrically arranged.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this testing instrument, the positioning component, through the connection of a worm gear and a worm, drives the threaded rod to rotate, causing the threaded sleeve to move downwards and fit against the main body of the testing instrument. The friction after fitting stabilizes the position of the slide. Compared to existing devices, this method does not directly compress the slide rod, thus avoiding deformation of the slide rod and affecting the movement of the slide. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] Given the current technology, the existing method of fixing the slide block is to directly insert the bolt into the slide block by rotating it to compress the slide rod and fix it by friction. However, this fixing method will cause deformation of the slide rod and affect the sliding of the slide block.

[0026] As shown in the attached figures, this utility model embodiment provides a wire diameter detector.

[0027] The instrument includes: a slide 12 on the top of the main body 11; a positioning component 2 on the bottom of the slide 12, the positioning component 2 including: a threaded rod 21 rotatably disposed on the bottom of the slide 12; a worm gear 22 fixedly sleeved on the outer side wall of the top end of the threaded rod 21; a threaded sleeve 23 sleeved on the outer side wall of the threaded rod 21 and threadedly connected to the threaded rod 21; a slider 24 fixedly disposed on the outer side wall of the top end of the slider 24; a vertical rod 25 with its top end passing through the slider 24 and fixedly connected to the slide 12; and a worm gear 26 with one end passing through the slide 12 and rotatably connected to the slide 12, and the other end meshing with the worm gear 22.

[0028] Specifically, the main body 11 and the slide 12 of the detector constitute a wire diameter detector, the principle of which mainly includes optical and electronic principles. The optical principle is based on optical imaging and image processing technology. It captures the image of the object being measured through a high-resolution camera and lens, and then uses a computer to preprocess the image, perform edge detection and binarization, etc., to extract the contour information of the object being measured. Then, by measuring the number of pixels in the contour, combined with the resolution and magnification of the camera, the actual wire diameter of the object being measured is calculated.

[0029] In use, after the sliding block 12 slides to the appropriate position on the main body 11 of the detector, it is only necessary to control the rotation of the worm 26. When the worm 26 rotates, one end will mesh with the worm wheel 22, driving the worm wheel 22 to rotate. At the same time, because the worm wheel 22 is fixedly connected to the threaded rod 21 and the top of the threaded rod 21 is rotatably connected to the sliding block 12, the rotation of the worm wheel 22 will drive the threaded rod 21 to rotate as well, and it will be threadedly connected to the threaded sleeve 23. The slider 24 on the outer wall of the threaded sleeve 23 slides on the upright 25 to restrict the rotation of the threaded sleeve 23. Therefore, when the threaded rod 21 rotates, it will drive the threaded sleeve 23 to move upward, so that the bottom end of the threaded sleeve 23 is in contact with the main body 11 of the detector, and the position of the sliding block is stabilized by the friction of the contact. Finally, the diameter of the automotive sewing thread is detected by the detector (in the attached figure, both sliding blocks 12 can slide on the main body 11 of the detector; the top of the left sliding block is used to fix one end of the decorative thread, and the right sliding block is equipped with a detection element to detect the diameter of the decorative thread).

[0030] In some embodiments, the positioning component 2 further includes a knob 27 disposed at one end of the worm gear 26.

[0031] The design of the knob 27 makes it easy to grip and control the rotation of the worm gear 26, while the grooves on the surface of the knob 27 can increase friction when rotating.

[0032] In some embodiments, the positioning component 2 further includes a baffle 28 disposed at the bottom end of the upright 25.

[0033] The design of the baffle 28 can prevent the slider 24 from disengaging from the upright 25 when it slides on the upright 25.

[0034] In some embodiments, the positioning component 2 further includes a rubber sleeve 29 fitted onto the bottom end of the threaded sleeve 23.

[0035] The design of the rubber sleeve 29 can reduce the wear at the bottom of the threaded sleeve 23, and the rubber material can increase the friction when in contact with it, making it more stable.

[0036] In some embodiments, the positioning component 2 further includes a protrusion 291 disposed on the top of the detector body 11.

[0037] The design of the protrusion 291 allows it to be inserted into the interior of the rubber sleeve 29 when it contacts the main body 11 of the detector, further increasing the friction.

[0038] In some embodiments, a connecting assembly 3 is provided on the outer side wall of the upright 25. The connecting assembly 3 further includes: a positioning hole 31 opened on the outer side wall of the rubber sleeve 29; a rotating rod 32 rotatably disposed on the outer side wall of the upright 25; and a spring 33 with retaining rings at both ends to facilitate the connection between the upright 25 and the rotating rod 32; and a plug 34 disposed at one end of the rotating rod 32.

[0039] After multiple uses, the rubber sleeve 29 needs to be replaced. Simply pinch the rotating rod 32 and rotate it while squeezing the spring 33 to compress it. This will cause the insert 34 at the bottom of the rotating rod 32 to disengage from the positioning hole 31, thus removing the rubber sleeve 29 from the bottom of the threaded sleeve 23.

[0040] In some embodiments, the connecting component 3 further includes a cone 35 disposed at one end of the insert block 34.

[0041] The design of the cone 35 makes it relatively easier to insert into the positioning hole 31.

[0042] In some embodiments, two sets of the connecting components 3 are symmetrically arranged.

[0043] The symmetrical design with two sets of supports can restrict both sides of the rubber sleeve, making the installation more secure.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
