[0027] Embodiment 1

[0028] As Figs. 1-4 shown, the utility model discloses the measuring protection board frock, including support platform 8, be equipped with the detection pressure plate 6 that can move up and down on support platform 8,

[0029] Support frame 2 is installed on support platform 8, and support frame 2 is located on one side of support platform 8 and is equipped with guide column 5, and the side of installing guide column 5 on support frame 2 is correspondingly equipped with hinged frame 3, and hinged frame 3 is hingedly installed with down pressure arm 1, and the lower side of hinged frame 3 correspondingly hinged down pressure arm 1 is equipped with guide cylinder 31, and the upper end of detection pressure plate 6 is installed with the down pressure column 4 extending upwards, and the down pressure column 4 is slidably installed into guide cylinder 31, and the upper end of down pressure column 4 and down pressure arm 1 are hingedly installed with connecting rod 9.

[0030] Detection pressure head 7 is correspondingly arranged on detection pressure plate 6.

[0031] Detection pressure plate 6 is transparent plate setting, and transparent plate can be made of organic glass (acrylic plate) or made of other materials, such as polycarbonate (PC) plate or PVC, PS and other material board. So that the detection personnel can clearly observe the detection point contact condition, further improve the accuracy of detection.

[0032] Guide column 5 is arranged to both ends of down pressure column 4 respectively. Through the both ends setting guide column 5 and the sliding connection of detection pressure plate 6, so that the movement stability of detection pressure plate 6 is better.

[0033] Detection pressure head 7 includes shell body 72, and detection needle 71 is slidably installed in shell body 72, and terminal 74 is threadedly connected to the end of shell body 72 away from detection needle 71, and compression spring 73 is arranged between terminal 74 and detection needle 71 in shell body 72.

[0034] The elastic connection of detection needle 71 is realized through compression spring 73, which avoids damaging the welding point or causing poor contact between detection needle 71 and part of the welding point due to the height difference of the welding point, thereby affecting detection.

[0035] The end of shell body 72 away from terminal 74 is provided with positioning ring 721. When shell body 72 is inserted into the lower end hole of detection pressure plate 6, positioning ring 721 is positioned, which ensures the accuracy of shell body 72 installation.

[0036] The placing table 81 is provided with the placing table 81 on the support platform 8 corresponding to the detection pressure head 7. The placing table 81 is a platform, and the battery protection plate can be placed directly; or the existing clamping equipment is used for clamping detection.

[0037] Working process or working principle:

[0038] During testing, the battery protection board is placed on the placement platform 81. By pressing down the pressure arm 1, the connecting rod 9 is moved downward. The connecting rod 9 presses down the pressure column 4, which in turn moves the detection pressure plate 6 downward, so that the detection needle 71 touches the solder joint of the battery protection board, thereby performing the test.

[0039] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
