[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0023] The following is combined with Figure 1-Figure 3 This embodiment is described in further detail.

[0024] See also Figure 1-Figure 3 A detection fixture in this embodiment includes a base 100, an upper side surface of the base 100 is provided with a T-shaped slide groove 101 along its length direction, and the upper side surface of the base 100 is evenly provided with a plurality of locking holes 102 along its length direction. The base 100 is relatively provided with clamping components for clamping both ends of a sun visor 112, and the clamping components include a certain clamp 110 and a movable clamp 111, and the movable clamp 111 is provided with a T-shaped slider 320 sliding in the T-shaped slide groove 101, and the movable clamp 111 is also provided with a positioning component for positioning the movable clamp 111.

[0025] In this embodiment, both ends of the sun visor 112 can be clamped by the clamping assembly and fixed, that is, the detection fixture can fix the sun visor 112, and the sun visor fixed on the detection fixture can be detected by using an external detection device;

[0026] Among them, through the coordinated setting of the fixed clamp 110 and the movable clamp 111, the two can fix and clamp the two ends of the sun visor 112, so as to realize the fixing of the sun visor 112 by the clamping assembly; wherein, through the movable setting of the movable clamp 111, the distance between it and the fixed clamp 110 can be adjusted, so that the clamping assembly can adapt to sun visors 112 of different lengths. Compared with the existing detection fixture, the detection fixture in this embodiment can be applicable to sun visors of different lengths, making it more applicable;

[0027] Among them, by setting the positioning component, it is possible to fix the movable clamp 111, and thus fix its position on the base, so that during the inspection, it will not move arbitrarily, causing the sun visor 112 to be stretched and damaged;

[0028] Among them, through the arrangement of the T-shaped slide groove 101 and the T-shaped slider 320, the movable clamp 111 can only move along the T-shaped slide groove 101 during the movement on the base 100, and the movement can be more stable.

[0029] In actual use, the fixed clamp 110 and the movable clamp 111 are both provided with a clamping cavity 201 for the corresponding end of the sun visor 112 to extend into, and the fixed clamp 110 and the movable clamp 111 are both threadedly provided with a threaded rod 210 extending into the clamping cavity 201, and the end of the threaded rod 210 located in the clamping cavity 201 is provided with a clamping plate 212, and the end of the threaded rod 210 located outside the clamping cavity 201 is provided with an operating handle 211, and the operating handle 211 is rotated to drive the clamping plate 212 to rise and fall in the clamping cavity 201 to achieve the sun visor 112. The sun visor 112 is squeezed and fixed; thus, in actual use, the two ends of the sun visor 112 are inserted into the corresponding clamping cavity 201, and the operating handle 211 is rotated clockwise to drive the threaded rod 210 to move downward, so that the clamping plate 212 moves down and presses against the sun visor 112, so that the sun visor 112 is fixed, and the operating handle 211 is rotated counterclockwise to drive the threaded rod 210 to move upward, so that the clamping plate 212 moves upward and separates from the sun visor 112. At this time, the fixation of the sun visor 112 is released to facilitate the subsequent removal and placement of the sun visor 112.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, the positioning assembly includes a locking cavity 300 arranged in the left and right side walls of the movable clamp 111, the locking cavity 300 is opened outward, a blocking plate 310 is provided at the opening of the locking cavity 300, a movable plate 301 is provided in the locking cavity 300 and is in contact with the inner wall thereof, a through hole is provided at the bottom wall of the locking cavity 300, a locking rod 302 with one end extending out of the through hole is provided on the movable plate 301, the locking rod 302 can be extended into the corresponding locking hole 102, and the locking cavity 300 is also provided with a driving assembly for driving the movable plate 301 to rise and fall.

[0031] In this embodiment, the movable plate 301 moves downward in the locking cavity 300 to drive the locking rod 302 to move downward, so that the locking rod 302 extends out of the through hole and extends into the corresponding locking hole 102, thereby fixing the position of the movable clamp 111; the movable plate 301 moves upward in the locking cavity 300 to drive the locking rod 302 to move upward, thereby making it disengage from the locking hole 102. At this time, the fixation of the movable clamp 111 is released, so that its position can be moved, so as to adjust its distance from the fixed clamp 110 to adapt to sun visors 112 of different lengths;

[0032] The side wall of the movable plate 301 is slidably fitted with the inner wall of the locking cavity 300, so that the moving direction of the movable plate 301 is limited, that is, it can only be lifted and lowered in the locking cavity 300, thereby ensuring that the locking rod 302 can be aligned with the through hole and extend into or out of the locking cavity 300;

[0033] In actual use, the locking rods 302 are relatively arranged in the locking cavity 300 at the left and right side walls of the movable clamp 111. Through this structure, both sides of the movable clamp 111 are fixed, and the fixing effect is better.

[0034] Among them, through the setting of the driving component, it is possible to control the upward and downward movement of the movable plate 301 in the locking cavity 300, thereby realizing the upward and downward movement of the locking rod 302.

[0035] like Figure 3 As shown, in this embodiment, the driving assembly includes a rotatable shaft 305 with one end extending out of the locking cavity 300, and the part of the shaft 305 located in the locking cavity 300 is sleeved with a gear 304, and the movable plate 301 is provided with a rack 303 meshing with the gear 304, and the gear 304 rotates to drive the locking rod 302 to move.

[0036] In this embodiment, the gear 304 rotates clockwise to drive the rack 303 to move upward, thereby moving the movable plate 301 upward, so that the locking rod 302 moves upward and disengages from the locking hole 102. At this time, the position of the movable clamp 111 can be moved. The gear 304 rotates counterclockwise to drive the rack 303 to move downward, thereby moving the movable plate 301 downward, so that the locking rod 302 moves downward and extends into the corresponding locking hole 102, so that the position of the movable clamp 111 is fixed.

[0037] like Figure 3 As shown, in this embodiment, a hand-cranked wheel 311 is provided at the end of the rotating shaft 305 extending out of the locking cavity 300 .

[0038] In this embodiment, both ends of the rotating shaft 305 are installed in the locking cavity 300 through bearings, thereby realizing the rotation setting of the rotating shaft 305. The hand-cranked wheel 311 is used to rotate the rotating shaft 305, thereby rotating the gear 304, which is simple and convenient to operate.

[0039] In actual use of this embodiment, a sliding groove is provided on the outer wall of the protruding end of the rotating shaft 305 along its axial direction, and a sliding block sliding in the sliding groove is provided in the hand-cranked wheel 311. The protruding end of the rotating shaft 305 is connected to a nut 313 through an external thread. The nut 313 is used to drive the hand-cranked wheel 311 to squeeze the blocking plate 310, thereby fixing the rotating shaft 305.

[0040] In this embodiment, the hand-cranked wheel 311 can preferably move axially along the rotating shaft 305 through the coordinated arrangement of the sliding block and the sliding groove. At the same time, the circumferential rotation of the hand-cranked wheel 311 can drive the rotating shaft 305 to rotate. Therefore, in actual use, by tightening the nut 313 to make the hand-cranked wheel 311 close to the extrusion plug 310, the rotating shaft 305 can be locked to prevent it from rotating accidentally, thereby affecting the actual use of the driving assembly. By loosening the nut 313 to release its fixation on the rotating shaft 305, the rotating shaft 305 can be rotated by the hand-cranked wheel 311.

[0041] Working principle: when the sun visor 112 needs to be tested, move the movable clamp 111 so that the ends of the sun visor 112 extend into the clamping cavities 201 on the fixed clamp 110 and the movable clamp 111 respectively, rotate the operating handle 211 of the fixed clamp 110 clockwise to drive the threaded rod 210 to move downward, so that the clamping plate 212 moves down and presses against the sun visor 112, thereby achieving the installation and fixation of the sun visor 112 on the clamping assembly, rotate the hand wheel 311 counterclockwise to drive the rotating shaft 305 to rotate counterclockwise, so that the gear 304 rotates counterclockwise, drives the rack 303 to move downward, and then moves the movable plate 301 downward, and finally moves the locking rod 302 downward and extends into the corresponding locking hole 102. At this time, the position of the movable clamp 111 is fixed, and the sun visor 112 can be tested by an external detection device.

[0042] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
