DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment one:

[0026] As shown in the drawings, Figures 1 to 5 Embodiment one of the utility model provides a kind of wire connection and disconnection mechanism for three-phase electric energy meter verification, for detecting three-phase electric energy meter. Specifically, including one long strip-shaped bottom plate 1, limiting component and detection component are provided on bottom plate 1, wherein limiting component is used to fix three-phase electric energy meter, and detection component is used to drive detection wire head 6 to move, so that detection wire head 6 can be inserted into the wiring port of three-phase electric energy meter, to detect the performance of three-phase electric energy meter.

[0027] As shown in the drawings, Figure 3 And Figure 4 Limiting component of the utility model includes two side clamping jaws 2 and two end face clamping jaws 4 and a limiting plate 3. Base 7 is fixed on bottom plate 1, and a first horizontal rod 8 is fixedly inserted on base 7, and two side clamping jaws 2 are symmetrically slidably installed on the first horizontal rod 8. Limiting plate 3 is located between two side clamping jaws 2, and the moving direction of side clamping jaw 2 on the first horizontal rod 8 is called horizontal direction. In order to be able to drive two side clamping jaws 2 to move relatively, the utility model is also fixed with the first vertical rod 9 perpendicular to the first horizontal rod 8 on the base 7, the sliding seat 10 is slidably sleeved on the first vertical rod 9, the two sides of the sliding seat 10 are symmetrically hinged with connecting rods 11, and the ends of the two connecting rods 11 away from the sliding seat 10 are respectively hinged with two side clamping jaws 2. In this way, when the sliding seat 10 moves on the first vertical rod 9, two side clamping jaws 2 can be driven to move relatively in horizontal direction through two connecting rods 11, so that three-phase electric energy meter can be abutted from the side of three-phase electric energy meter.

[0028] The utility model discloses a fixed installation clamping air cylinder 17 on bottom plate 1, the movable end of clamping air cylinder 17 is fixed with second tension spring 18, and the first vertical rod 9 of the one side of slide 10 away from base 7 is sleeved with drive seat 12, and second tension spring 18 is fixedly connected with drive seat 12, and drive seat 12 is also fixed with the first tension spring 13 of fixed connection of slide 10. When clamping air cylinder 17 contracts, clamping air cylinder 17 moves drive seat 12 through second tension spring 18, and drive seat 12 moves slide 10 by pulling first tension spring 13, and then makes two side clamping jaws 2 clamp the side of three-phase electric energy meter. It needs to be explained that first tension spring 13 and second tension spring 18 can also transmit thrust, that is, when clamping air cylinder 17 elongates, drive seat 12 can be moved through second tension spring 18, and drive seat 12 can also move slide 10 by pushing first tension spring 13, and in this way, clamping air cylinder 17 can drive two side clamping jaws 2 to approach each other or move away from each other.

[0029] And in order to be able to limit three-phase electric energy meter's displacement in the longitudinal direction, that is, in the axial direction of first vertical rod 9. As shown in Figure 4 The utility model discloses a fixed installation guiding seat 14 on bottom plate 1, and guiding seat 14 is slidably connected with second vertical rod 15, and second vertical rod 15 is parallel with first vertical rod 9, one end of second vertical rod 15 is fixedly connected with drive seat 12, and the other end is fixed with second horizontal rod 16, and second horizontal rod 16 is parallel with first horizontal rod 8, and end face clamping jaw 4 is slidably installed on second horizontal rod 16, and end face clamping jaw 4 is also slidably installed on side clamping jaw 2. Therefore, when two side clamping jaws 2 move along first horizontal rod 8, end face clamping jaw 4 will also move synchronously in the transverse direction, and when second horizontal rod 16 moves along the axial direction of second vertical rod 15, second horizontal rod 16 can drive end face clamping jaw 4 to move in the longitudinal direction, so as to cooperate with the limiting plate 3 in the longitudinal direction and resist three-phase electric energy meter.

[0030] Since two side clamping jaws 2 can limit three-phase electric energy meter's freedom of movement in the transverse direction, and end face clamping jaw 4 can cooperate with limiting plate 3 to limit three-phase electric energy meter's freedom of movement in the longitudinal direction, the position of three-phase electric energy meter on bottom plate 1 is limited.

[0031] Example two:

[0032] As shown in Figure 1 And Figure 2 As shown in the embodiment, the utility model discloses the detection assembly designed including fixed detection cylinder 21 on bottom plate 1 and setting in the plug -in module 5 of detection cylinder 21 output end. As shown in Figure 2 Detection cylinder 21 expands, and detection line head 6 can be inserted into the wiring hole of three-phase electric energy meter, and plug -in module 5 is connected with detection equipment, so as to test the functional state of three-phase electric energy meter.

[0033] Embodiment three:

[0034] On the basis of embodiment one and embodiment two, the utility model discloses the threaded mounting of adjusting rod 19 on base 7, and the fixed limiting plate 3 is at the end of adjusting rod 19, like this, when rotating adjusting rod 19, can change the relative position of limiting plate 3 and base 7. Adjusting rod 19 is parallel with the first longitudinal rod 9, and limiting plate 3 is slidably connected with bottom plate 1, so that when rotating adjusting rod 19, the adjustment of the position of limiting plate 3 can be completed in the longitudinal direction, so that the limiting assembly of the utility model can be used for clamping and fixing various specifications of three-phase electric energy meter.

[0035] The utility model discloses the rotatory installation of multiple compression rollers 20 on the opposite side of two side clamping jaws 2. This makes the friction between three-phase electric energy meter and side clamping jaw 2 be rotational friction, which reduces the resistance when end face clamping jaw 4 pushes three-phase electric energy meter to move.

[0036] When using, first adjusting rod 19 is adjusted, and limiting plate 3 is adjusted to the appropriate position, then three-phase electric energy meter is placed between the bottom plate 1 of two side clamping jaws 2, and the clamping cylinder 17 is started, and the clamping cylinder 17 pulls the second tension spring 18 and then pulls the drive seat 12 to move, so that two side clamping jaws 2 abut against the side of three-phase electric energy meter, at this time, the slide 10 can not move further, therefore the drive seat 12 will further lengthen the first tension spring 13 and continue to move, so that end face clamping jaw 4 can abut against three-phase electric energy meter on limiting plate 3, thereby completing the fixation of three-phase electric energy meter. Then the detection cylinder 21 is started, and the detection wire head 6 is inserted into the wiring hole of three-phase electric energy meter, and detection can be carried out.

[0037] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model also intends to include these modifications and variations.
