Abstract
The utility model discloses an improved structure of a spring protection sleeve, and relates to the technical field of spring protection sleeves. Including well pipe step and spring protection cover, the spring protection cover outside is provided with well pipe step, and the bottom of spring protection cover is less than the root setting of spring. The spring protection sleeve is reasonable in structural design, the middle pipe step is added to move the spring protection sleeve downwards, the spring protection sleeve and the root of the spring are not on the same horizontal plane, and the gap of the step is small, the space caused by the inclination of the spring and the diameter of the spring steel wire is larger than the gap, so that the spring is prevented from moving due to transverse vibration, the spring steel wire is prevented from running into the gap between the middle pipe step and the spring protection sleeve, and the spring is damaged.
Description
Technical Field
The utility model relates to the technical field of spring protection sleeves, in particular to an improved structure of a spring protection sleeve.
Background
The spring protection sleeve and the spring root of the existing utility model are on the same horizontal plane, and the spring can be vibrated longitudinally and transversely in the machine operation. Receive longitudinal vibration be, this spring housing can be fine protection spring, but when receiving horizontal vibrations, because spring and spring protective sheath are at same horizontal plane, the spring produces the displacement, leads to the spring steel wire to run the gap between well pipe step and the protective sheath, and under the effect of the power, the spring root fracture causes the spring to damage.
In conclusion, the utility model designs an improved structure of the spring protection sleeve.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide an improved structure of a spring protection sleeve, which is reasonable in structural design, can well protect a spring and ensures the normal operation of the device.
In order to achieve the purpose, the utility model is realized by the following technical scheme: an improved structure of a spring protection sleeve comprises a middle pipe step and a spring protection sleeve, wherein the middle pipe step is arranged on the outer side of the spring protection sleeve, and the bottom of the spring protection sleeve is lower than the root of a spring.
Preferably, the spring protection sleeve and the spring root are not in the same horizontal plane.
The utility model has the beneficial effects that: the spring protection sleeve is reasonable in structural design, the middle pipe step is added to move the spring protection sleeve downwards, the spring protection sleeve and the root of the spring are not on the same horizontal plane, and the gap of the step is small, the space caused by the inclination of the spring and the diameter of the spring steel wire is larger than the gap, so that the spring is prevented from moving due to transverse vibration, the spring steel wire is prevented from running into the gap between the middle pipe step and the spring protection sleeve, and the spring is damaged.
Drawings
The utility model is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides a spring protection sleeve improves structure, includes well pipe step 1 and spring protection sleeve 2, and the 2 outsides of spring protection sleeve are provided with well pipe step 1, and the bottom of spring protection sleeve 2 is less than the root setting of spring 3.
It is noted that the spring protection sleeve 2 and the root of the spring 3 are not in the same horizontal plane.
This embodiment's structural design is reasonable, has increased a well pipe step and then has moved down spring protecting sleeve, makes spring protecting sleeve and spring root not on same horizontal plane, because the step gap is little the space that causes with spring steel wire self diameter in spring self inclination and can be greater than the gap, guarantees that the spring can not be because of the produced displacement of horizontal vibrations, leads to the spring steel wire to run to the gap between well pipe step and the spring protecting sleeve, causes the spring to damage.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
