[0007] Preferably, the rotary clamping mechanism includes a rotary shaft and a clamping arm. The rotary shaft is rotatably mounted on the fixture seat, and the clamping arm is fixed on the rotary shaft. The clamping arm is used to clamp the charging pile controller to be tested onto the connecting pin. The rotary shaft works in conjunction with the rotation limiting mechanism.

[0008] Preferably, the rotation limiting mechanism includes: a first toothed ring, a second toothed ring, and a spring. The first toothed ring is fixed on the clamp seat and can mesh with the second toothed ring. The second toothed ring is mounted on the rotating shaft and can only move relative to the rotating shaft in the axial direction. The second toothed ring cannot rotate relative to the rotating shaft.

[0021] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 3 As shown, this utility model discloses a box-type charging pile controller tester, including: an operation display box 1, a box cover 2, an operation display panel 3, a positioning seat 4, a clamp seat 5, connecting wires 6, connecting pins 7, a rotary clamping mechanism 8, and a rotation limiting mechanism 9; the operation display panel 3 and the positioning seat 4 are installed on the top of the operation display box 1, the operation display panel 3 is located next to the positioning seat 4, and the positioning seat 4 has a positioning groove 40 for the positioning seat 4 to be inserted; a detection execution circuit is installed inside the operation display box 1, and the detection execution circuit... One end of the connecting wire 6 is connected to the operating display panel 3, and the other end of the connecting wire 6 is electrically connected to the connecting pin 7. The connecting pin 7 is used to electrically connect to the charging pile controller under test. The connecting pin 7 is mounted on the clamping base 5, and a rotatable rotary clamping mechanism 8 is mounted on the clamping base 5. The output end of the rotary clamping mechanism is used to press the charging pile controller under test onto the connecting pin 7. A rotation limiting mechanism 9 is installed at the connection between the rotary clamping mechanism 8 and the clamping base 5 to limit the rotation of the rotary clamping mechanism 8. The top of the operating display box 1 can be fastened by the box cover 2.

[0023] The rotary clamping mechanism 8 includes a rotating shaft 81 and a clamping arm 82. The rotating shaft 81 is rotatably mounted on the fixture base 5, and the clamping arm 82 is fixed on the rotating shaft 81. The clamping arm 82 is used to clamp the charging pile controller under test onto the connecting pin 7. The rotating shaft 81 interacts with the rotation limiting mechanism 9. By rotating the rotating arm and the clamping arm 82, the charging pile controller under test can be clamped or moved away.

[0024] The rotation limiting mechanism 9 includes a first toothed ring 91, a second toothed ring 92, and a spring 93. The first toothed ring 91 is fixed on the clamp seat 5 and can mesh with the second toothed ring 92. The second toothed ring 92 is mounted on the rotating shaft 81 and can only move relative to the rotating shaft 81 along its axis. The second toothed ring 92 cannot rotate relative to the rotating shaft 81. The clamp seat 5 is fixed to one end of the spring 93, and the other end of the spring 93 is fixed to the second toothed ring 92. Under the elastic force of the spring 93, the second toothed ring 92 can be kept engaged with the first toothed ring 91. Pulling the second toothed ring 92 disengages it from the first toothed ring 91. The first toothed ring 91 and the second toothed ring 92 cooperate to position the rotating shaft 81, preventing the rotating shaft 81 and the clamping arm 82 from rotating arbitrarily and ensuring that the clamping arm 82 can remain in the position of clamping the charging pile controller to be tested.

[0025] A guide rod 83 is fixed on the rotating shaft 81, and the guide rod 83 guides the movement of the second gear ring 92. The guide rod 83 forms the basis for the relative mounting of the rotating shaft 81 and the second gear ring 92.

[0026] The guide rod 83 has a cuboid or hexagonal structure. The shape of the guide rod 83 restricts the rotation of the second toothed ring 92; of course, the guide rod 83 can also have other structures.

[0027] A cover sleeve 50 is installed on the clamp seat 5, and a pusher arm 94 is fixed to the second toothed ring 92, with the pusher arm 94 protruding from the cover sleeve 50. The function of the cover sleeve 50 is to cover the first toothed ring 91 and the second toothed ring 92, preventing external leakage and easy entry of impurities, which could affect the meshing of the first toothed ring 91 and the second toothed ring 92.

[0028] The inner wall of the positioning groove 40 is recessed to form a positioning hole 41, into which the booster arm 94 extends. Under the elastic force of the spring 93, the booster arm 94 can extend into the positioning hole 41.

[0029] The booster arm 94 has a notch 940. This allows the booster arm 94 to disengage from the positioning hole 41 by pushing the inner wall of the notch 940 when removing the clamp seat 5 from the positioning seat 4, thus facilitating the removal of the clamp seat 5.

[0030] When it is necessary to locate the charging pile controller to be tested, firstly, pull the auxiliary arm, and the second toothed ring 92 on the auxiliary arm disengages from the first toothed ring 91; then, rotate the auxiliary arm, and the auxiliary arm drives the rotating arm to rotate through the guide rod 83, thereby causing the clamping arm 82 to rotate to the position of clamping the charging pile controller to be tested.

[0031] The booster arm 94 on the rotation limiting mechanism 9 not only has the function of boosting and rotating the second toothed ring 92, but also has the function of positioning the clamping seat 5 when it is retracted into the positioning seat 4. When removing the clamping seat 5 from the positioning seat 4, firstly, the inner wall of the notch 940 is squeezed to move the booster arm and the second toothed ring 92 into the clamping seat 5, and the booster arm disengages from the positioning hole 41 on the positioning seat 4 and remains in this state; then, the clamping seat 5 is manually disengaged from the positioning seat 4 to achieve disassembly.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
