[0002] In the assembly of 3C product button gaskets, large equipment loaded with a newly purchased measurement system is used to automatically assemble button gaskets, which makes the automatic debugging time too long. The online client hopes to have a measuring jig to synchronously measure the same button bracket to observe whether the data collected by the equipment and the data collected by the measuring jig are relevant, so as to judge whether the equipment is debugged OK. The working principle of the current carrier in the engineering verification test stage (i.e., EVT, Engineering Verification Test) is as follows: (1) The operator puts the button bracket into the carrier seat; (2) Cover the cover plate; (3) Place the carrier on the VR_6000 equipment platform to perform height scanning of the button bracket. In the engineering verification test stage, only the carrier is used for measurement, and the reasons for data errors are as follows: Due to the machining errors between the cover plate and the button bracket, the cover plate is adsorbed on the carrier seat by magnetic force, thereby fixing the Z-direction position of the button bracket by magnetic force, and there is only one pressing point at one end of the pressing head, so it is easy for the button bracket to be floatingly pressed, resulting in unclear lens movement during scanning, and further making the measured value of the height of the button bracket collected by the VR_6000 equipment platform inaccurate.

[0030] Please refer to Figures 1 to 12 As shown, the present utility model discloses a measuring fixture for measuring the height of a product. The measuring fixture of the present utility model includes a holding module 1 and a pressing and locking module 2. The holding module 1 includes a base body 11 and a cover plate 12. The base body 11 is provided with a stop block 111, and the cover plate 12 is covered above the base body 11 so as to be able to limit and hold the product between the cover plate 12 and the base body 11. The pressing and locking module 2 includes a first main body frame 21, a pressing plate 22 and a locking hook 23. The pressing plate 22 is positioned by the first main body frame 21 and abuts above the cover plate 12 for pressing the product; the locking hook 23 is provided on the first main body frame 21 and can be clamped and positioned with the stop block 111.
[0031] Please refer to Figures 2 to 8 As shown, the stop block 111 has a first inclined surface 1111 and a stop surface 1112, and the locking hook 23 has a second inclined surface 231 and a locking surface 232. After the first inclined surface 1111 is disengaged from the second inclined surface 231, the stop surface 1112 is in place in cooperation with the locking surface 232. During the process of the locking hook 23 coming into contact and cooperation with the stop block 111, the locking hook 23 deflects. The deflecting force can be due to the elastic force of the locking hook 23 itself. The upper end of the locking hook 23 is fixed on the first main body frame 21 and only the end of the locking hook 23 deflects; or the locking hook 23 itself does not have an elastic force, instead the upper end of the locking hook 23 is pivotally connected to the first main body frame 21, and not only the end of the locking hook 23 deflects but the locking hook 23 is integrally deflected under the action of the following first spring 24. In the specific embodiment of the present utility model, the form in which the locking hook 23 is integrally deflected under the action of the first spring 24 is adopted.
[0032] Please refer to Figure 5 and Figure 10 As shown, the pressing and locking module 2 includes a first spring 24. The locking hook 23 is rotatably connected to the first main body frame 21. The first spring 24 is provided on the first main body frame 21 and abuts against the locking hook 23 to be able to provide a deflecting force to the locking hook 23. Under the deflecting force of the first spring 24, the locking hook 23 is clamped and fixed with the stop block 111 without detachment. One end of the first spring 24 is positioned on the first main body frame 21 and the other end of the first spring 24 abuts against the middle position between the upper end and the end of the locking hook 23 to be able to provide an elastic acting force for the locking hook 23 to be integrally deflected.
[0033] Therefore, compared with the prior art, in the present utility model, the pressing plate 22 of the pressing and locking module 2 abuts against the cover plate 11 of the holding module 1 to press the key bracket product below the cover plate 11; and in the present utility model, the pressing and locking module 2 is locked to the holding module 1 by the way that the locking hook 23 of the pressing and locking module 2 is snap-fitted with the stopper 111. Thus, the present utility model can strengthen the acting force pressing on the key bracket product, avoid the upward floating of the key bracket product during the measurement process, and thus can realize the high-precision measurement of the height of the key bracket.
[0034] Please refer to Figures 1 to 10 as shown, the measuring fixture of the present utility model further includes an unlocking module 3. The unlocking module 3 includes a second main frame 31 and an unlocking hook 32 located on the second main frame 31. The unlocking hook 32 is in abutting cooperation with the locking hook 23 for unlocking between the locking hook 23 and the stopper 111.
[0035] Please refer to Figure 5 and Figure 10 as shown, the unlocking module 3 includes a second spring 33. The second spring 33 is arranged on the second main frame 31 and abuts against the unlocking hook 32 to be able to provide a driving force to the unlocking hook 32. Under the action of the driving force of the second spring 33, the locking hook 23 and the stopper 111 are disengaged from the clamping and fixing. The function of the first spring 24 is to provide an automatic locking force to the unlocking hook 32, and the function of the second spring 33 is to provide an automatic unlocking force to the unlocking hook 32.
[0036] Please refer to Figure 3 、 Figure 5 and Figure 10 as shown, the unlocking hook 32 has a third inclined surface 321, and the third inclined surface 321 has an inclination angle consistent with that of the first inclined surface 1111 so as to be able to contact and cooperate with the second inclined surface 231. Since both the third inclined surface 321 and the first inclined surface 1111 need to cooperate with the second inclined surface 231, the first inclined surface 1111 contacts the second inclined surface 231 during the automatic locking process of the unlocking hook 32, while the third inclined surface 321 contacts the second inclined surface 231 during the automatic unlocking process of the unlocking hook 32. Since the cooperation stages are different but the contacting and cooperating objects are the same, it is understandable and necessary that the third inclined surface 321 has an inclination angle consistent with that of the first inclined surface 1111.
[0037] Please refer to Figure 2As shown in the figure, the first main body frame 21 includes two cross beam brackets 211 extending in the first direction and two handles 212 extending in the second direction. Opposite ends of each handle 212 are respectively connected to opposite ends (such as the left end or the right end) of a corresponding cross beam bracket 211, so that the two cross beam brackets 211 and the two handles 212 enclose a receiving space. There are multiple pressing plates 22, and the multiple pressing plates 22 are arranged parallel to each other in the receiving space, and opposite ends of each pressing plate 22 are connected to the two cross beam brackets 211. Therefore, when the operator holds one handle 212 with each of the left and right hands and presses the pressing and locking module 2 onto the holding module 1 from top to bottom, the multiple pressing plates 22 are exactly pressed above the cover plate 12 to press the product tightly and ensure the consistency of the product height.
[0038] Please refer to Figure 5 、 Figure 11 and Figure 12 As shown in the figure, the pressing and locking module 2 includes an elastic component 25 positioned on the cross beam bracket 211. The elastic component 25 includes a third spring 251 and a spring seat 252. The spring seat 252 is slidably positioned up and down with the cross beam bracket 211, and the third spring 251 is clamped between the cross beam bracket 211 and the spring seat 252. Each pressing plate 22 straddles above the cover plate 12, and opposite ends of each pressing plate 22 are respectively fixed to a spring seat 252, and the elastic component 25 elastically presses the pressing plate 22 against the cover plate 12. For the specific fixing manner of opposite ends of each pressing plate 22 to a spring seat 252, please refer to Figure 11 , a lapping platform 2521 is provided on the inner side of the spring seat 252 facing the receiving space, and opposite ends of each pressing plate 22 are respectively fixed to the lapping platform 2521 on the inner side of a spring seat 252.
[0039] Please refer to Figure 5 and Figure 11 As shown in the figure, the elastic component 25 further includes a stop screw 253. The top end of the third spring 251 abuts against the cross beam bracket 211, and the bottom end of the third spring 251 abuts against the stop screw 253; the spring seat 252 is provided with a through hole 2520 with a hollow interior, and the stop screw 253 is locked into the lower end of the through hole 2520 to contact the third spring 251. By adjusting the locking depth of the stop screw 253 in the through hole 2520, the compression force of the third spring 251 can be changed. For example: adjusting the stop screw 253 upward so that the depth of the stop screw 253 in the through hole 2520 becomes larger, then the compression amount of the third spring 251 is increased and the elastic force becomes larger; adjusting the stop screw 253 downward so that the depth of the stop screw 253 in the through hole 2520 becomes smaller, then the compression amount of the third spring 251 is decreased and the elastic force becomes smaller.
[0040] Please refer to Figure 5As shown, the extending direction of the third spring 251 is defined as the up-down direction, and the extending directions of the first spring 24 and the second spring 33 are perpendicular to the up-down direction, that is, the first spring 24 and the second spring 33 extend in the left-right direction. The unlocking hook 32, the locking hook 23, and the stopper 111 are at least a pair in the left-right direction and are arranged symmetrically. It is easy to understand that the locking hook 23 and the stopper 111, which are at least a pair and arranged symmetrically in the left-right direction, can ensure that when the pressing and locking module 2 presses the holding module 1 from top to bottom, balanced acting forces are provided on both the left and right sides, and the operation feel is strong.
[0041] In summary, first, in the present utility model, the pressing plate 22 of the pressing and locking module 2 abuts against the cover plate 11 of the holding module 1 to press the key bracket product below the cover plate 11; during the downward pressing process of the compression module 2, first, the second inclined surface 231 and the first inclined surface 1111 come into contact. Under the pushing of the first inclined surface 1111, the locking hook 23 rotates relative to the first main body frame 21. When the first inclined surface 1111 and the second inclined surface 231 are separated, under the elastic force of the first spring 24, a deflecting force capable of being clamped with the stopper 111 is provided for the locking hook 23, and the stopper surface 1112 and the locking surface 232 come into contact. At this time, the compression module 2 is released. Under the action of the elastic component 25, the stopper surface 1112 and the locking surface 232 abut against each other to achieve the locked state of the measuring jig. In the present utility model, the pressing and locking module 2 is locked to the holding module 1 by the clamping and positioning of the locking hook 23 of the pressing and locking module 2 and the stopper 111. Therefore, the present utility model can strengthen the acting force on the key bracket product, avoid the upward floating of the key bracket product during the measurement process, and thus can achieve high-precision measurement of the height of the key bracket; second, when the pressing and locking module 2 is pressed from top to bottom to the holding module 1 by hand, the pressing and locking module 2 and the holding module 1 are automatically locked; third, the present utility model further includes an unlocking module 3 to automatically unlock the pressing and locking module 2 and the holding module 1. When unlocking is required, the compression module 2 is continuously pressed downward, and the stopper surface 1112 and the locking surface 232 are separated. Since the elastic force of the second spring 33 is greater than the elastic force of the first spring 24, the unlocking hook 4 pushes the locking hook 23 to rotate away from the stopper 111, and the locking hook 23 is completely separated from the stopper 111 to achieve unlocking. Therefore, while the present utility model avoids the upward floating of the key bracket product during the measurement process and can achieve high-precision measurement of the height of the key bracket, it also has the beneficial effect of simple operation.

The understanding of the present utility model should be based on those skilled in the relevant technical field. Although this specification has described the present utility model in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify or make equivalent substitutions to the present utility model, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
