When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the utility model as detailed in the accompanying claims.
Referring to fig. 1, an embodiment of the present utility model provides a concave value measuring apparatus 10, where the concave value measuring apparatus 10 is used for measuring a concave value of a concave surface 21 in a display device 20. The display device 20 includes a display panel (not shown in the figure) and a frame 22, where the display panel and/or the frame 22 may be concave, and the concave 21 may be a concave 21 of the display panel or a concave 21 of the frame 22, which is not limited.
Referring to fig. 2 to 4, the concave measuring device 10 includes a mounting base 11, a probe 12, a baffle 13, and an elastic member 14.
The mounting seat 11 forms a first channel 111, the mounting seat 11 is provided with scale marks extending along the extending direction of the first channel 111, the probe 12 penetrates through the first channel 111 and can slide in the first channel 111, and the part of the probe 12 in the first channel 111 is provided with an indicator 15; the baffle 13 is connected with the part of the probe 12 outside the first channel 111, and the baffle 13 protrudes out of the probe 12; the elastic member 14 is located between the mounting seat 11 and the baffle 13.
In the embodiment of the present utility model, when the probe 12 slides in the first channel 111, the movement amount of the probe 12 relative to the mounting seat 11 can be obtained according to the change value of the scale mark corresponding to the indicator 15 on the probe 12. After the movement amount of the probe 12 relative to the mounting seat 11 is obtained, the probe 12 can be reset under the action of the elastic restoring force of the elastic member 14, so that the movement amount can be measured next time when the probe 12 moves.
The concave value measuring device 10 of the embodiment of the present utility model measures the concave value of the concave surface 21 of the display apparatus 20: referring to fig. 1, the concave value measuring device 10 may be placed corresponding to the concave surface 21 of the display device 20, and then the baffle 13 is pressed or the end of the baffle 13 is set by the pressing probe 12, so that the probe 12 slides in the first channel 111 until the end of the probe 12 far away from the baffle 13 contacts the concave surface 21 of the display device 20, at this time, the concave value of the concave surface 21 can be obtained by obtaining the motion of the probe 12 relative to the mounting seat 11, and compared with the measurement mode of pulling a fish wire and adding a plug gauge in the related art, the measurement efficiency is higher; in addition, since the concave value measuring device 10 is directly placed on the concave surface 21, and the concave value measuring device 10 is not easy to deform, compared with a fish wire which is easy to bend and deform and affects the alignment of the plug gauge, the embodiment of the utility model can also ensure higher measuring precision. After the movement amount of the probe 12 with respect to the mounting seat 11 is obtained, the shutter 13 is released or one end portion of the probe 12 where the shutter 13 is provided is released, and the probe 12 is restored to the initial position by the elastic restoring force of the elastic member 14 so that the concave value measuring device 10 is used next time.
In order to avoid abrasion of the concave surface 21 caused by contact of the probe 12 with the concave surface 21, an end surface of the probe 12 remote from the baffle 12 may be hemispherical, and the like, which is not limited thereto.
It should be noted that, to increase the speed of acquiring the movement amount of the probe 12 relative to the mounting seat 11, the initial position of the probe 12 may correspond to the zero position of the scale line. Of course, the initial position of the probe 12 may correspond to any graduation mark other than the zero position, which is not limited.
The extending direction of the first channel 111 may be a linear direction, and the sliding of the probe 12 in the first channel 111 may be a movement along the linear direction, so as to improve the smoothness of the sliding of the probe 12 in the first channel 111 and improve the measurement efficiency of the concave value measuring device 10.
The mounting seat 11 has a first surface 112 and a second surface 113 opposite to each other along the extending direction of the first channel 111, two ends of the first channel 111 respectively penetrate through the first surface 112 and the second surface 113, the baffle 13 is located at a side of the first surface 112 of the mounting seat 11, and the elastic member 14 is located between the baffle 13 and the first surface 112. When the baffle 13 is pressed or the probe 12 is pressed to set one end of the baffle 13, the probe 12 slides in the first channel 111, and the elastic piece 14 is pressed by the reduced interval between the baffle 13 and the first surface 112, so that the elastic piece 14 is in a deformed state; when the baffle 13 is released or the probe 12 is disposed at one end of the baffle 13, the elastic member 14 will be transformed from the deformed state to the restored state under the elastic restoring force of the elastic member 14, so as to drive the probe 12 to slide in the first channel 111 for restoring.
In measuring the concave value of the concave surface 21 using the concave value measuring device 10, the concave value measuring device 10 first needs to be positioned in contact with the concave surface 21, that is, the concave value measuring device 10 has a positioning surface 16, and the positioning surface 16 is used for positioning in contact with the concave surface 21 before the concave value of the concave surface 21 is measured.
In an exemplary version, referring to fig. 1, the mount 11 may have a locating surface 16. For example, the second surface 113 of the mounting 11 may be configured as a locating surface 16. In another exemplary embodiment, referring to fig. 5 and 6, the concave value measuring device 10 further includes a positioning rod 17, where the positioning rod 17 is located on a side of the mounting seat 11 facing away from the baffle 13 and is connected to the mounting seat 11, the positioning rod 17 is provided with a second channel 171 corresponding to the first channel 111, the probe 12 can also be disposed through the second channel 171, and a surface of the positioning rod 17 facing away from the mounting seat 11 is configured as a positioning surface 16 for contacting the concave surface 21 in the concave value measuring device 10.
In the measurement of the concave surface 21, if the positioning surface 16 of the concave surface 21 is positioned in contact with the edge of the concave surface 21, the gap between the positioning surface 16 and the concave surface 21 may substantially reflect the concave value of the concave surface 21, and if the positioning surface 16 is to be in contact with the edge of the concave surface 21, the size of the positioning surface 16 will be relatively large. Therefore, if the second surface 113 of the mounting seat 11 is configured as the positioning surface 16, the size of the mounting seat 11 will be relatively large, and if the positioning rod 17 has the positioning surface 16, the size of the positioning rod 17 need only be designed to be large, and the size of the mounting seat 11 may not be limited.
The extending direction of the positioning surface 16 may be perpendicular to the extending direction of the first channel 111, so that when the probe 12 detects the concave value of the concave surface 21 when sliding in the first channel 111, the movement amount of the probe 12 relative to the mounting seat 11 may approximately reflect the concave value of the concave surface 21.
Further, the positioning rod 17 may be a telescopic rod, and the length of the positioning rod 17 may be adjusted according to the size of the concave surface 21, so as to increase the application range of the concave value measuring device 10. It should be noted that the positioning rod 17 may be an inexorable rod, and may be flexibly designed according to practical requirements, which is not limited thereto.
The positioning rod 17 and the mounting seat 11 may be detachably connected, and since the size of the positioning rod 17 is larger than that of the mounting seat 11, the positioning rod 17 and the mounting seat 11 may be detachably connected, and when the concave value measuring device 10 is transported or idle, the positioning rod 17 and the mounting seat 11 may be detached to reduce the occupied space. It should be noted that the positioning rod 17 and the mounting seat 11 may be fixedly connected, and the like, and the present utility model is not limited thereto.
Referring to fig. 6, the cross-section of the second channel 171 of the positioning rod 17 may generally match the cross-section of the probe 12; that is, it is only necessary that the probe 12 be able to slide in the second channel 171; for example, if the cross-section of probe 12 is circular, then the cross-section of second channel 171 is also circular.
Referring to fig. 7, the cross section of the second channel 171 on the positioning rod 17 may also be substantially elongated, for example, the elongated shape may extend along the extending direction of the positioning surface 16, so that the mounting base 11 may move relative to the positioning rod 17, and after the mounting base 11 moves relative to the positioning rod 17, the probe 12 on the mounting base 11 can still pass through the second channel 171 on the positioning rod 17.
The mounting seat 11 may be directly disposed in the middle of the positioning rod 17, or may perform fine adjustment processing with respect to the positioning rod 17 before measurement, so as to improve the measurement accuracy of the concave value of the concave surface 21.
In the embodiment of the present utility model, the mounting seat 11 may be an integrally formed structure, and the mounting seat 11 may also include two sub-mounting seats 114 that are detachably connected. When the mounting seat 11 includes two sub-mounting seats 114 that are detachably connected, the first channel 111 is formed between the two sub-mounting seats 114, so that the two sub-mounting seats 114 are connected after the part of the probe 12 is placed between the two sub-mounting seats 114, which is beneficial to improving the convenience of assembly between the probe 12 and the mounting seat 11.
Note that, when the mount 11 includes two sub-mounts 114, at least one of the two sub-mounts 114 is provided with a scale line. For example, one of the sub-mounts 114 may be provided with graduation marks, or both sub-mounts 114 may be provided with graduation marks. If the two sub-mounting seats 114 are provided with scale marks, the scale marks provided on the two sub-mounting seats 114 may be the same; for example, the graduation marks on one sub-mount 114 may be 0-2.5mm, and the graduation marks on the other sub-mount 114 may be 0-2.5mm, where the initial positions of the two may or may not be corresponding. Of course, the graduation marks provided on the two sub-mounts 114 may also be different; for example, the graduation marks on one sub-mount 114 may be 0-2.5mm, the graduation marks on the other sub-mount 114 may be 0-3.5mm, etc., and the initial positions of the two may or may not be corresponding.
The scale mark on the mounting seat 11 can be arranged corresponding to the first channel 111, so that the indicator 15 on the probe 12 can clearly indicate a certain position on the scale mark when the probe 12 is stationary and after the probe 12 slides in the first channel 111, and the reading is convenient.
The scale marks on the mounting seat 11 are arranged corresponding to the first channel 111, and may cover at least part of the scale marks for the projection of the inner wall surface of the first channel 111 on the mounting seat 11, or may cover the scale marks for the projection of the inner wall surface of the first channel 111 on the mounting seat 11, and the distance between the inner wall surface of the first channel and the scale marks satisfies the preset distance. The preset distance is greater than or equal to 0 and less than or equal to 1mm, and the like, and the preset distance can be flexibly designed according to actual requirements, and is not limited.
