SUMMERY OF THE UTILITY MODEL

The utility model provides a spring end cover, compression spring and extension spring has solved among the prior art that the spring is formed by the steel wire spiral of making the spring mostly, so the both ends face of spring is not the plane, when the installation uses, has slightly to rock easily, and the occasion that unsuitable required precision is high, is exactly that the both ends of the steel wire of spring are directly exposed, scrapes the people easily, also not aesthetic defect.

The technical scheme of the utility model is realized like this:

the spring end cover comprises a cover body, wherein a spring slot is formed in the middle of one end face of the cover body, and at least one inclined slot corresponding to the spiral steel wire head end of a spring is formed in the inner bottom face of the spring slot.

Further, the number of the inclined slots is two, three, four or five, and the depths of the inclined slots are different.

Further, the bottom of the spring slot is provided with an axial through hole.

The utility model also provides a compression spring, including the compression spring body, the one end or the both ends cover of compression spring body have as before a spring end cover.

The utility model also provides an extension spring, including the extension spring body, the one end of extension spring body is provided with couple I or link I, and the other end of extension spring body is the conical end that reduces, and conical end endotheca has a threaded rod, and the inner of threaded rod is connected with the head, and the transverse width of head is less than the internal diameter of extension spring body, and the transverse width of head is greater than the minimum internal diameter of conical end, and conical end is stretched out to the outer end of threaded rod, and the threaded rod overcoat has preceding a spring end cover, be connected with threaded hole's connector on the threaded rod, fixedly connected with length adjustment couple on the connector, be connected with the chain on connector or the couple, chain end-to-end connection has couple II or link II.

Further, the length adjusting hook is a plate-shaped hook, and a chain connecting hole connected with the chain is formed in the plate-shaped hook.

Further, the chain is formed by connecting a plurality of detachable chain rings in sequence.

The utility model has the advantages that: the utility model discloses a spring end cover can overlap at the tip of spring, and the slope slot is inserted to the spiral steel wire head end of spring, makes the terminal surface of spring form the plane, because the uneven problem of rocking and the precision is low that causes of spring end when solving the use.
