DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a speed limiter test instrument detection device includes a mounting plate 1, a fixing mechanism 2 is fixedly connected to the front side of the mounting plate 1, a vertical plate 3 is fixedly connected to the upper surface of the mounting plate 1 near the rear side, a rotating mechanism 4 is rotatably connected to the upper inner side of the vertical plate 3, a motor 5 is fixedly sleeved on the upper side of the rotating mechanism 4, and a driving wheel 6 is fixedly connected to the output end of the motor 5.

[0026] It should be noted that the motor 5 drives the driving wheel 6 to rotate, and the driving wheel 6 contacts the speed limiter roller, so that the driving wheel 6 drives the speed limiter roller to rotate, and the speed limiter roller is tested.

[0027] like Figure 1 , Figure 3 As shown, the fixing mechanism 2 includes a triangular boss 21, the rear side of the triangular boss 21 is fixedly connected to the front middle part of the mounting plate 1, the front side of the triangular boss 21 is slidably connected to two push buttons 22 symmetrically distributed on the left and right, the rear side of the push button 22 is connected to a splint 23 through a round rod, and the splint 23 is located on the inner side of the mounting plate 1.

[0028] It should be noted that the triangular boss 21 is in the shape of an isosceles triangle. Pushing the push button 22 to both sides will cause the push button 22 to slide left and right while also sliding forward and backward. Only the left and right sliding of the push button 22 drives the clamping plate 23 to move forward and backward.

[0029] like Figure 3 , Figure 4 As shown, two fixed blocks 25 symmetrically distributed up and down are movably sleeved on both sides of the inner sides of the two push buttons 22, and telescopic rods 26 are fixedly connected to the upper and lower sides of the inner middle vertical plates of the two push buttons 22. The ends of the telescopic rods 26 that are away from each other are fixedly connected to the inner sides of the fixed blocks 25 that are away from each other, and the outer walls of the four telescopic rods 26 are movably sleeved with springs 27.

[0030] It should be noted that the telescopic rod 26 can change its own length, and the spring 27 is used to push the fixed block 25, so that the telescopic rod 26 is in the longest state. At the same time, the fixed blocks 25 on the upper and lower sides are pinched to compress the telescopic rod 26, and the fixed blocks 25 are released. The spring 27 pushes the fixed blocks 25 to reset.

[0031] like Figure 3-Figure 5 As shown, the rear sides of the four fixed blocks 25 that are away from each other are fixedly connected with a plurality of evenly distributed claws 28, and the upper and lower edges of the left and right inclined surfaces on the front side of the triangular boss 21 are fixedly connected with a plurality of evenly distributed teeth 24, and the rear sides of the claws 28 are meshedly connected with the inner sides of the teeth 24.

[0032] It should be noted that the latch teeth 24 are used to fix the claws 28, so that the push button 22 can only slide in one direction to the left or right. When the fixing block 25 is pinched to make the claws 28 disengage from the latch teeth 24, the push button 22 can slide freely to the left or right.

[0033] like Figure 2 , Figure 6 As shown, the front sides of the two push buttons 22 are both provided with friction patterns.

[0034] It should be noted that the friction pattern is used to increase the friction between the hand and the push button 22 , making it easier for the user to push the push button 22 .

[0035] like Figure 6 As shown, the rotating mechanism 4 includes a rotating seat 41, the outer side of the rotating seat 41 is rotatably connected to the upper inner side of the vertical plate 3, the upper inner side of the vertical plate 3 is rotatably connected to a worm 42, the rear side of the rotating seat 41 is fixedly connected to a gear ring 43 near the edge, the outer wall of the worm 42 is fixedly connected to a first gear 44 near the right end, the front side of the first gear 44 is meshingly connected to the rear side of the gear ring 43 near the right side, the inner rear surface of the vertical plate 3 is rotatably connected to a worm wheel 45 near the upper side, the front side axis of the worm wheel 45 is fixedly connected to a second gear 46, the lower side of the worm wheel 45 is meshingly connected to the upper side of the worm 42, the inner side of the rotating seat 41 is rotatably connected to a rotating plate 48, the rear side of the rotating plate 48 is fixedly connected to a third gear 47 near the bottom, the upper side of the third gear 47 is meshingly connected to the lower side of the second gear 46, and the outer side of the motor 5 is fixedly sleeved on the inner side of the rotating plate 48.

[0036] It should be noted that, by rotating the rotating seat 41, the rotating seat 41 drives the ring gear 43 to rotate, and when the ring gear 43 rotates, it drives the first gear 44 to rotate, and when the first gear 44 rotates, it drives the worm 42 to rotate, and when the worm 42 rotates, it drives the worm wheel 45 to rotate, and when the worm wheel 45 rotates, it drives the second gear 46 to rotate, and when the second gear 46 rotates, it drives the third gear 47 to rotate, and when the third gear 47 rotates, it drives the rotating plate 48 to rotate. There is self-locking between the worm 42 and the worm wheel 45, so that the worm 42 can drive the worm wheel 45 to rotate, but the worm wheel 45 cannot drive the worm 42 to rotate.

[0037] The working principle of the utility model is as follows: first, the rotating seat 41 is rotated so that the rotating seat 41 drives the ring gear 43 to rotate. When the ring gear 43 rotates, it drives the first gear 44 to rotate. When the first gear 44 rotates, it drives the worm 42 to rotate. When the worm 42 rotates, it drives the worm wheel 45 to rotate. When the worm wheel 45 rotates, it drives the second gear 46 to rotate. When the second gear 46 rotates, it drives the third gear 47 to rotate. When the third gear 47 rotates, it drives the rotating plate 48 to rotate. There is a self-locking property between the worm 42 and the worm wheel 45, so that the worm 42 can drive the worm wheel 45 to rotate, but the worm wheel 45 cannot drive the worm 42 to rotate. By rotating the rotating seat 41, the rotating plate 48 is rotated, so that the rotating plate 48 drives the driving wheel 6 to contact the speed limiter roller. Due to the self-locking property between the worm wheel 45 and the worm 42, the rotating plate 48 cannot drive the rotating seat 41 in the reverse direction, so that the rotating plate 48 is fixed, thereby reducing the error caused by vibration. Finally, the shape of the triangular boss 21 is an isosceles triangle. The spring 27 is used to push the fixing block 25, so that the extension rod 26 is in the longest state, and the fixing blocks 25 on the upper and lower sides are pinched at the same time, so that the extension rod 26 is compressed, and the fixing block 25 is released, and the spring 27 pushes the fixing block 25 to reset. The latching teeth 24 are used to fix the claws 28, so that the push button 22 can only slide in one direction to the left and right. When the fixing block 25 is pinched so that the claws 28 are disengaged from the latching teeth 24, the push button 22 can slide freely to the left and right. By pushing the push button 22 to the sides, the clamping plate 23 moves backward and clamps the two sides of the side wall of the speed limiter with the rear wall of the mounting plate 1, so that the device is fixed on the speed limiter. Pressing the fixing block 25 causes the push button 22 to be no longer fixed, so that the clamping plate 23 relaxes its clamping, which is convenient to install, simple to disassemble, and convenient to operate.
