Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of single-phase national grid guide rail meter testing tooling, in particular to a single-phase national grid guide rail meter testing tooling. Background Art
[0002] The use of single-phase and three-phase rail meter test devices is increasing day by day. Because it realizes that the crimping tooling can be crimped up and down at the same time, the production efficiency is far superior to the previous manual wiring type, and the tooling quality is excellent and widely used. In actual use, the following shortcomings are found: 1) When testing the rail meter, different models of meters need to adjust the upper and lower positions of the upper tooling in advance to reach a suitable position, and when crimping, the basket screws of the rail meter need to be tightened to make the copper block of the rail meter fully contact the meter rod. This process is too cumbersome. 2) When crimping some special rail meters, beveled meter rods are often used. The crimping method is used to improve efficiency, but in actual use, the crimping will not be enough (there is a gap between the meter rod and the crimped copper block), resulting in too large an error reading difference or a crimping gap at the meter rod, resulting in excessive heat and damage to the rail meter; in addition, the rail meter is usually only suitable for one type of meter. If the meter type needs to be changed, the distance of the upper half of the tooling must be adjusted, resulting in reduced production efficiency. Summary of the invention
[0003] In view of the above problems, the utility model proposes a single-phase State Grid rail meter testing tool, which solves the problem that the existing same type of meter needs to adjust the upper and lower positions of the upper tool in advance to reach a suitable position, and the basket screws of the rail meter need to be tightened during crimping to make the copper block of the rail meter fully contact with the meter rod. This process is too cumbersome, and in actual use, the crimping will be insufficient (a gap will appear between the meter rod and the crimped copper block), resulting in excessive error reading difference or a crimping gap at the meter rod, resulting in excessive heat and damage to the rail meter; in addition, the rail meter is usually only suitable for one type of meter, and if the meter type needs to be changed, the distance of the upper half of the tool must be adjusted, resulting in reduced production efficiency.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A single-phase national grid rail meter test tool, comprising: a base; a plurality of lower meter rods are mounted on the base; a first slider rear outlet window is provided on the base;
[0006] A lifting frame, wherein the lifting frame is mounted on the base;

[0030] Example 1
[0031] like Figure 1 As shown, the technical solution adopted by the utility model is as follows:
[0032] A single-phase State Grid rail meter test tool, comprising: a base 1, a meter lifting frame 2, a top plate 3, a guide structure 4 and an upper meter rod base 5; the base is provided with a plurality of lower meter rods 6; the base is provided with a first slider rear outlet window 7; the meter lifting frame is mounted on the base; the top plate is mounted on the meter lifting frame at one end away from the base; the guide structure is mounted on the bottom of the top plate outside the meter lifting frame; the upper meter rod base is mounted on the upper part of the meter lifting frame; there are a plurality of upper meter rods 31 on the left and right of the bottom of the upper meter rod base; the upper meter rod is provided with a partition plate 8, and the upper meter rod base is provided with a second slider rear outlet window 9. The guide structure comprises a guide column 10 mounted on the top plate and the bottom plate, the guide column is sleeved with a guide member 11, and a limit member 12 is mounted on the end of the guide column away from the top plate.
[0033] A first slide groove 13 is provided on the outer side of the meter lifting frame, and a meter lifting frame pressing block 14 is installed on the first slide groove. An upper meter rod base fixing piece 15 is installed on the upper meter rod base. A fixing frame 16 is installed on the top plate, and the fixing frame includes a pair of side panels 17. A second slide groove 18 is provided on the inner side wall of the side panel, and a transverse axis 19 is installed between the second slide grooves of the pair of side panels. A downward pressing assembly 20 is installed on the fixing frame, and the downward pressing assembly includes a downward pressing handle 21. The end of the downward pressing handle is hinged on the top of a pair of side panels, and an arc-shaped bent handle 22 is hinged on the outer side of the downward pressing handle, and the arc-shaped bent handle is hinged on the transverse axis. The lower meter rod includes a rod body 23, and a first mounting groove 24 is installed on the rod body. A spring piece 25 is installed on one side of the rod body. The spring piece includes a head 26, an outer sheet 27 and a tail 28. The head is bent and inserted into the mounting groove, and the tail is fixed to the outer surface of the rod body by fasteners.
[0034] The spring piece is made of 0.8mm stainless steel and bent into a suitable arc. After the finished product is crimped to the national grid rail meter, it needs to be pressed hard and released slightly to press the upper and lower meter rods into the rail meter. After the meter rod is fully pressed down, the elastic force of the spring piece is used to make the other side without the spring piece closer to the copper block of the rail meter.
[0035] The outer wall of the rod body is provided with a second mounting groove 29, in which a spring 30 is installed, and the end of the spring is against the outer sheet. The outer sheet is a stainless steel 0.8mm iron sheet, and the guide rail meter basket screw is tightened to the loosest position, and the upper meter rod is pressed into the interior, and one side of the iron sheet is against the outer copper sheet so that the inner surface without the iron sheet fits tightly with the copper sheet, greatly reducing the gap. A card slot 32 is provided on the inner wall of the meter lifting frame, and a meter lifting frame partition 33 is provided in the card slot.
[0036] When this embodiment is implemented, crimping: first adjust the push-down handle to the appropriate position, then put the guide rail meter into the meter lifting frame, put your hand on the push-down handle and press down hard, the meter will be blocked by the upper meter rod first, and then press down together after the upper surface of the meter touches the upper panel of the meter lifting frame, and the crimping is completed after the large pressure crimping stroke is completely completed and the upper meter rod and the lower meter rod are completely entered into the guide rail meter.
[0037] Lifting the meter: Place your hand on the push-down handle and push upward to make the upper meter rod separate from the guide meter first. After the bottom of the guide meter contacts the bottom plate of the meter lifting frame, the guide meter separates from the lower meter rod due to the upward pulling force of the push-down handle. Continue to move upward until the left and right guide columns have moved away. The limit parts and guide parts interfere with each other so that the meter lifting frame lifts the guide meter completely to complete the lifting of the meter.
[0038] Replacement of watch type: There is a shelf in the watch carrying frame. The space inside the watch carrying frame can be adjusted according to the length of the watch type to achieve compatibility of two watch types.
[0039] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
