Embodiment 1

A kind of lamination cartridge type spring with Anti-inclining function, as shown in Figs 1-4, including spring body 1, spring body 1 Outer sheath be equipped with layering sleeve 2, layering sleeve 2 be made of upper bush 21 and lower sleeve 22, upper bush 21 is fixed on spring sheet On the upper end lateral wall of body 1, the inner sidewall upper end of upper bush 21 is equipped with weldering line 211, and lower sleeve 22 is fixed under spring body 1 It holds on lateral wall, the inner sidewall lower end of lower sleeve 22 is equipped with weld ddge 221.

In the present embodiment, the internal diameter of upper bush 21 is greater than the outer diameter of spring body 1, is socketed in upper bush 21 just The outside of spring body 1, and not will increase the friction between upper bush 21 and spring body 1.

Further, weldering line 211 is in screw thread round, and weldering line 211 is an integral molding structure with upper bush 21, specifically, weldering Line 211 is weldingly fixed on 1 top one of spring body and encloses on the lateral wall of nearly annulus, keeps upper bush 21 upper with spring body 1 It holds fixed or moves up and down.

In the present embodiment, the internal diameter of lower sleeve 22 is greater than the outer diameter of upper bush 21, lower sleeve 22 and 21 movable sleeve of upper bush It connects, and avoids the normal use of the frictional influence spring body 1 between lower sleeve 22 and upper bush 21.

Further, the inner shape of weld ddge 221, size and shape, the size of weldering line 211 are all the same, and weld ddge 221 is under Sleeve 22 is an integral molding structure, and specifically, nearly circle is enclosed in the bottom end one that the inner sidewall of weld ddge 221 is weldingly fixed on spring body 1 On the lateral wall of ring, allow lower sleeve 22 as the lower end of spring body 1 is fixed or moves up and down.

In the present embodiment, the whole height after upper bush 21 and the socket cooperation of lower sleeve 22 is less than spring body 1 and is pressed onto most Height when low, it can be ensured that spring body 1 can be forced into minimum in use, will not influence spring body 1 (especially Be compress class spring) normal use.

In addition, in the present embodiment, when the sum of height of upper bush 21 and lower sleeve 22 is greater than 1 normal condition of spring body Highly, when spring body 1 is in normal condition, bottom end a part of upper bush 21 is connected in lower sleeve 22, avoids spring Run-off the straight leads to the case where sleeve can not be accurately socketed up and down when ontology 1 is pressurized.

Embodiment 2

As second of embodiment of the utility model, in order to avoid there is occurring in use upper bush 21 under The case where 22 positional shift of sleeve can not be accurately socketed, the present invention staff makes following improvement on the basis of embodiment 1, as A kind of preferred embodiment, as seen in figs. 5-6, the outer sheath of spring body 1 are equipped with sliding sleeve 3, and sliding sleeve 3 is by outer sleeve 31 It is formed with inner sleeve 32, the inner sidewall upper end of outer sleeve 31 is equipped with upper weld ddge 311, if rule is equipped on the inner sidewall of outer sleeve 31 The lateral wall upper end rule of dry sliding slot 312, inner sleeve 32 is equipped with several sliding blocks 321.

In the present embodiment, the internal diameter of inner sleeve 32 is greater than the outer diameter of spring body 1, and the internal diameter of outer sleeve 31 is greater than inner sleeve 32 outer diameter is socketed outer sleeve 31, inner sleeve 32 and spring body 1 successively, and reduces the frictional force between each component.

Further, upper weld ddge 311 is in threaded annular, and upper weld ddge 311 is an integral molding structure with outer sleeve 31, upper weld ddge The top one that 311 inner sidewall is weldingly fixed on spring body 1 is enclosed on the lateral wall of nearly annulus, allows outer sleeve 31 with bullet The top of spring ontology 1 is fixed or is carried out up and down.

Further, the quantity of sliding slot 312 is at least one, sliding slot 312 is equal with the quantity of sliding block 321 and position one by one Corresponding, sliding block 321 and the sliding of sliding slot 312 are clamped, and the quantity of sliding slot 312 and sliding block 321 is both preferably two in the present embodiment, makes Inner sleeve 32 can be consolidated with outer sleeve 31 and is equably slidably connected.

Further, when the whole height after inside and outside sleeve is fully mated is forced into minimum less than or equal to spring body 1 Height, it is ensured that spring body 1 may be compressed to minimum, avoid influence spring body 1 normal work.

Further, whole height when inside and outside sleeve does not stress is less than or equal to height when 1 normal condition of spring body Degree, and the whole height be greater than 1 normal condition of spring body when height half, it is ensured that spring body 1 in forced compression not Prominent or inclination can occur easily.

The lamination cartridge type spring with Anti-inclining function of the utility model when in use, directly by the top of spring body 1 Bottom both ends be separately fixed on the suitable position using structure can normal use, in use process, such as spring body 1 is carried out Stretch, then upper bush 21 with spring body 1 upper end motion, lower sleeve 22 with spring body 1 lower end motion, such as to bullet The force of spring ontology 1 is compressed, then spring body 1 sets back under the action of own resilient first, when spring body 1 is in When normal condition, the bottom part of upper bush 21 has been socketed in lower sleeve 22, at this time 1 forced compression of spring body, compression Path be limited in up and down in sleeve, will not there is a situation where prominent or inclinations, and spring body 1 may be compressed to most It is small.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
