Abstract
The utility model discloses a transformer combined floodgate combined spring, including changeing board, spring, screwing pole, lower shank of screw, the spring is the drum type, and the diameter is big in the middle of the spring promptly, and the both ends diameter is little, and maximum diameter is 57 0.5mm, and minimum diameter is 48.5 0.5mm, improves the one time with product life under the unchangeable prerequisite of assurance power value, the inside fastening in spring both ends has the nut, the nut is linked with screwing pole and lower shank of screw cooperation respectively, change the board and be connected with the screwing pole, can decompose the power that the spring received during the combined floodgate, reduce the spring breakage possibility.
Description
Technical field
This utility model belongs to five metals spring art, is specifically related to a kind of Transformer Close cluster spring.
Background technology
Transformer Close spring, the automatic closing when voltage occurs abnormal or too high, close a floodgate moment, spring, by strong impacts, easily causes spring breakage.After switching-in spring lost efficacy, transformator can not close a floodgate, and causes serious consequence.
Summary of the invention
For the drawbacks described above overcoming prior art to exist, the purpose of this utility model is, a kind of Transformer Close cluster spring is provided, increase steering, the power that spring is subject to during combined floodgate, can be decomposed, reduce spring breakage probability, by changing spring outward appearance for drum spring, two ends external diameter is constant, increases intermediate outer, is ensureing that life of product is doubled on the premise of constant by force value.
The Transformer Close cluster spring that this utility model provides, including flap, spring, screwing bar, lower shank of screw, described spring is drum type, i.e. spring mid diameter is big, and two ends diameter is little, and maximum gauge is 57 ± 0.5mm, and minimum diameter is 48.5 ± 0.5mm；Being fastened with nut inside both ends of the spring, described nut coordinates with screwing bar and lower shank of screw respectively and links；Described flap is connected with screwing bar.
The Transformer Close cluster spring that this utility model provides, simple in construction, easy to operate, it has the beneficial effects that, by increasing flap, decomposes impulsive force when closing a floodgate, simultaneously by changing spring profile for drum spring, it is ensured that force value, improves life of product.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment.
Figure marks:
1. flap；2. middle springs；3. end spring；4. nut；5. screwing bar；6. descend shank of screw.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the Transformer Close cluster spring providing this utility model is described in detail.
Embodiment
With reference to Fig. 1, the Transformer Close cluster spring of the present embodiment, including flap 1, spring, screwing bar 5, lower shank of screw 6, described spring is drum type, i.e. spring mid diameter is big, and two ends diameter is little, and maximum gauge is 57 ± 0.5mm, and minimum diameter is 48.5 ± 0.5mm；Being fastened with nut 4 inside both ends of the spring, described nut 4 coordinates with screwing bar 5 and lower shank of screw 6 respectively and links；Described flap 1 is connected with screwing bar 5.
The Transformer Close cluster spring of the present embodiment, increase steering, the power that spring is subject to can be decomposed when closing a floodgate, reduce spring breakage probability, being drum spring by changing spring outward appearance, end spring 3 external diameter is constant, increases middle springs 2 external diameter, on the premise of ensureing that force value is constant, life of product is doubled.
Claims (3)
