[0028] Embodiment

[0029] Referring to Figures 1 to 4 As shown, the present utility model provides a slide rail shaking detection device, which includes a sliding member 1, a detection member 6 and an adjusting member 7; the sliding member 1 is matched with the slide rail 2, the adjusting member 7 is used to adjust the sliding member 1 to move in a direction perpendicular to the slide rail 2 on the slide rail 2, and the detection member 6 is used to detect the shaking amount of the sliding member 1 in this direction and quantify it into a specific value for output; the slide rail shaking detection device can quantify the shaking condition of the slide rail 2, facilitate equipment debugging and improve the stability of the equipment.

[0030] Specifically, referring to Figure 1 As shown, the slide rail shaking detection device further includes a base plate 8 and a vertical plate 9 that are perpendicular to each other. The surface of the base plate 8 is provided with a groove 81 for fixing the slide rail 2. The slide rail 2 extends in a first direction. The sliding member 1 is configured to be slidably connected to the slide rail 2 and move along the slide rail 2 in the first direction. The sliding member 1 includes a slider 3 and a connecting block 4; the slider 3 is connected to the slide rail 2. One side surface of the slider 3 in a second direction has a chute 31 that can cooperate with the slide rail 2 for sliding. The other side surface of the slider 3 in the second direction is fixedly connected to the connecting block 4, and the second direction is perpendicular to the first direction.

[0031] Further, referring to Figure 2 and Figure 3 As shown, the connecting block 4 has a set of detection surfaces 5, the detection surfaces 5 are arranged as inclined surfaces, and the detector 6 realizes the detection of the shaking amount of the slide rail through the cooperation with the detection surfaces 5. In some embodiments, the connecting block 4 can be arranged as a wedge-shaped block or a special-shaped block with an inclined surface; in the preferred embodiment of the present invention, the connecting block 4 includes a fixing portion 41 and a wedge portion 42, and the fixing portion 41 is arranged on at least one side of the wedge portion 42 in the first direction. The fixing portion 41 is fixedly connected to the slider 3. Preferably, the fixing portion 41 is provided with mounting holes 4101, the mounting holes 4101 extend along the second direction and are penetrated by fasteners, and the fixing portion 41 is provided with four groups of the mounting holes 4101.

[0032] Next, the wedge portion 42 has the detection surface 5; the detection surface 5 is oppositely arranged with the detector 6 in the second direction, the detection surface 5 includes a first end 51 and a second end 52, and the connection line of the first end 51 and the second end 52 is perpendicular to the first direction; in the second direction, the first end 51 is closer to the plane where the slide rail 2 is located than the second end 52, the second end 52 is closer to the detector 6 than the first end 51, and the distance between the first end 51 and the plane where the slide rail 2 is located is less than the distance between the second end 52 and the plane where the slide rail 2 is located.

[0033] Next, referring to Figure 5 As shown, the included angle between the connection line of the first end 51 and the second end 52 and the plane where the slide rail 2 is located is α, that is, the included angle between the detection surface 5 and the plane where the slide rail 2 is located is α; the length of the connection line of the first end 51 and the second end 52 is set as the extension length of the detection surface 5 and is set as L1; the length of the positive projection of the detection surface 5 along the second direction on the plane where the bottom plate 8 is located is L2, and L2>0; the length of the positive projection of the detection surface 5 along the third direction on the plane where the vertical plate 9 is located is L3, and the third direction is perpendicular to the plane where the first direction and the second direction are located. Then,

[0034] cosα = L2 / L1;

[0035] sinα = L3 / L1;

[0036] tanα = L3 / L2.

[0037] Preferably, the included angle α is set as 45°.

[0038] Specifically, referring to Figure 1As shown, the detection piece 6 is fixed to the vertical plate 9 and is disposed opposite to the detection surface 5 in the second direction; an installation portion 91 is provided on the vertical plate 9 for fixing the detection piece 6 and adjusting the position of the detection piece 6 in the third direction. The detection piece 6 is set as a height sensor for detecting the height difference between the detector and the position on the detection surface 5 opposite thereto.

[0039] Specifically, referring to Figure 1 As shown, the adjusting member 7 is used to adjust the sliding member 1 along the third direction to abut against the slide rail 2; through research by the inventor of this case, it is found that when the sliding member 1 slides along the first direction, it has a sway amount in the third direction, and too large or too small of the sway amount will affect the sliding of the sliding member 1. The adjusting member 7 includes a screw rod, and a threaded hole 43 is provided through the connecting block 4 along the first direction. At least a part of the screw rod is located in the threaded hole 43 and is threadedly connected to the connecting block 4. The area of the screw rod outside the connecting block 4 is used to trigger and move the connecting block 4 to drive the sliding member to abut against both sides of the slider 3 in the third direction along the third direction. Preferably, the fixing portion 41 and the wedge portion 42 are provided as an integrally formed structure, which is convenient for the overall movement of the connecting block 4.

[0040] Specifically, the slide rail sway detection device further includes a control portion, and the control portion is connected to the output end of the detection piece 6; the height detection data of the detection piece 6 is output to the control portion to obtain a sway amount value.

[0041] The working principle of the slide rail sway detection device of the present utility model is as follows:

[0042] Referring to Figure 5 As shown, the sliding member 1 is placed above the slide rail 2 and slides along the first direction, touching the area of the screw rod outside the connecting block 4, and the connecting block 4 and the slider 3 are moved along the third direction towards one side until the sliding member 1 abuts against the slide rail 2, reaching the position with the maximum sway amount. At this time, the detection piece 6 detects the height difference between it and the position opposite on the inclined plane in the second direction, obtains the detection data d1 and outputs it to the control portion.

[0043] Subsequently, touch the screw rod to move the connecting block 4 along the third direction towards the other side until the sliding member 1 abuts against the other side of the slide, reaching the position with the maximum sway amount, and the detection piece 6 outputs the detection data d2 and outputs it to the control portion.

[0044] Referring to Figure 5 As shown, when the detection piece 6 faces point A, it is the first detection, and when the detection piece 6 faces point B, it is the second detection. The length of the line connecting point A and point B on the detection surface 5 in the positive projection on the vertical plate 9 along the third direction is L4; then,

[0045] L4 = |d1 - d2|;

[0046] The length of the projection of the line connecting point A and point B on the detection surface 5 along the second direction on the bottom plate 8 is L5. Since the sliding member 1 generates a wobble in cooperation with the slide rail 2 along the second direction, the maximum wobble amount in the second direction during the wobbling process is L5. Since both point A and point B are located on the detection surface 5, and the line connecting them is parallel to the line connecting the first end 51 and the second end 52 during wobbling, according to trigonometric functions,

[0047] tanα = L4 / L5;

[0048] In some embodiments, after obtaining L4 from the d1 and d2 data of the detection member 6, the wobble amount of the slide rail needs to be calculated according to the inclination angle of the detection surface 5. In the preferred embodiment of the present invention, when α is 45°, tanα = 1, L2 = L3 and L4 = L5; the wobble amount of the slide rail 2 is obtained by the difference between the two detection data of the detection member 6, which simplifies the measurement process; when α is too large, the space occupied by the detection device in the second direction is too large, and when α is too small, the numerical difference detected by the detection member 6 is small, which affects the accuracy of the test results. The inclination angle of the detection surface 5 of 45° can reasonably control the volume of the device and detect the change in the height value during the wobbling of the sliding member 1, meeting the accuracy requirements.

[0049] It should be supplemented and explained in this embodiment that: the slide rail wobble detection device includes a control part for connecting the detection member 6, and the software programs for assisting its operation are all existing and replicable software programs, which do not constitute the innovation points of this application.

[0050] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
