[0034] A plurality of weights 21 are connected with the presser foot 16 through a connecting piece, and the required number of weights 21 is determined through a control piece.

[0035] Specifically, as Figure 1As shown, the connecting piece includes a vertical rod 18 fixedly connected on the presser foot 16, and the vertical rod 18 is threadedly connected with a sleeve 20, the vertical rod 18 is slidably connected with the weight 21, and the upper surface of the weight 21 is provided with a corresponding slot 22, the lower surface is fixedly connected with a clamping block 23 matched with the corresponding slot 22, and the presser foot 16 is also provided with a clamping groove 19 matched with the clamping block 23.

The sleeve 20 can make the plurality of weights 21 closely adhere to each other, preventing the weights 21 from sliding under the force on the vertical rod 18. When the sleeve 20 is separated from the vertical rod 18 during rotation, the weight 21 can be removed from the vertical rod 18, and a weight 21 with different pressure can be replaced.

[0036] Specifically, as shown in the figure, Figure 4 The control piece includes a hook groove 24 formed on the weight 21, a horizontal groove 25 formed on the sliding block 7, and a circular rod 26 fixedly connected in the horizontal groove 25, the circular rod 26 is slidably connected with a horizontal block 27, the horizontal block 27 is threadedly connected with a rotating rod 29, the bottom end of the rotating rod 29 is rotatably connected with a hook block 30, the hook block 30 extends into the hook groove 24, and the sliding block 7 is further provided with a limiting piece limiting the rotating rod 29.

[0037] A spring 28 is sleeved on the circular rod 26, one end of the spring 28 is fixedly connected with the inner side wall of the horizontal groove 25, the other end is fixedly connected with the side wall of the horizontal block 27, and the spring 28 pushes the horizontal block 27 to move until the hook block 30 on the horizontal block 27 extends into the hook groove 24.

[0040] After the cover block 31 is rotated away from the rotating rod 29 and the bottom block 34 is aligned with the circular groove 35, under the elastic force of the spring 36, the cover block 31 moves downward to be close to the sliding block 7, and the bottom block 34 extends into the circular groove 35.

[0041] In summary, the measuring device provided by the embodiment is installed:

The screw rod 12 is rotated, so that the slider 7 at the slot 10 is deformed, the size of the slot 10 is reduced, and the digital display 13 is clamped, that is, the connection between the digital display 13 and the slider 7 is completed.

[0043] The screw sleeve 20 is rotated, so that the screw sleeve 20 moves to the upper end of the vertical rod 18, at this time, the plurality of weights 21 on the vertical rod 18 can move in the vertical direction. Then the cover block 31 is lifted, so that the sleeve slot two 33 is separated from the rotating rod 29, and under the elastic force of the spring one 28, the cross block 27 moves close to the weight 21. The cover block 31 is rotated, so that the cover block 31 is rotated away from the rotating rod 29, and the bottom block 34 at the bottom of the cover block 31 is aligned with the corresponding circular groove 35, under the elastic force of the spring two 36, the bottom block 34 is clamped with the circular groove 35, the cover block 31 is fixed with the slider 7, then the cover block 31 at this time will not affect the subsequent thickness measurement. Until the hook block 30 extends into the hook slot 24 of the weight 21 which is in contact with the presser foot 16, the rotating rod 29 is rotated and moved upward, then the hook block 30 drives all the weights 21 to move upward, then the presser foot 16 at this time is not pressed by the weight 21, until the uppermost weight 21 is in contact with the screw sleeve 20.

[0044] The screw slot 17 of the presser foot 16 is connected with the elastic expansion rod 14 of the digital display 13 through threads, the rotating rod 5 is rotated by the handle 6, until the slider 7 moves downward together with the digital display 13, until it moves to the appropriate height. At this time, the presser foot 16 is in contact with the detection table 2 under the cooperation of the elastic expansion rod 14, then the value of the digital display 13 is adjusted to zero.

[0045] During thickness measurement:

[0046] According to the measured sample, the required pressure is determined to select the required number of weights 21, each weight 21 is marked with a weight value, and the required number of weights 21 corresponding to the required pressure can be obtained by simple addition calculation.

[0047] For example, one weight 21 is required, the cross block 27 is pushed to move, until the hook block 30 is separated from the hook slot 24, the lowermost weight 21 is released, that is, the required number of weights 21 is released. Under the action of the weight, the required weight 21 falls onto the presser foot 16. The rotating rod 29 is rotated, so that the rotating rod 29 and the hook block 30 move upward, until the hook block 30 is aligned with the second weight 21 above the presser foot 16. The pushing force on the cross block 27 is released, and under the elastic force of the spring one 28, the cross block 27 and the hook block 30 move, until the hook block 30 extends into the hook slot 24 of the second weight 21. At this time, the rotating rod 29 is reversely rotated, so that the rotating rod 29 moves upward, under the action of the hook block 30, the unnecessary weights 21 all move upward and away from the presser foot 16.

[0048] Due to the thickness of the sample moving, the elastic telescopic rod 14 in the process of telescoping, the presser foot 16 will not contact the hook block 30 on the weight 21 not required to use.

[0049] Lift the presser foot 16 upward, place the measured sample on the detection table 2, loosen the lifting force on the presser foot 16, the elastic telescopic rod 14 drives the presser foot 16 to move downward together, and press the sample tightly. At this time, the detection result can be viewed through the digital display meter 13.

[0050] The above description of the embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will accord with the widest scope consistent with the principles and novel features disclosed herein.
