Buffer spring for automobile engine protection

Abstract

The invention provides a buffer spring for automobile engine protection. The buffer spring comprises a spring framework and supporting plates, the top and the bottom of the spring framework are provided with the supporting plates in a welding mode correspondingly, the spring framework comprises reinforcing pieces, binding belts and clamping bolts, the plurality of reinforcing pieces are tightly attached to the surface of the spring framework, every two reinforcing pieces are arranged to be in a group to be used in a cooperating mode, for each group of the reinforcing pieces, the binding beltsare arranged on the two sides of the two reinforcing pieces in a nested mode, the clamping bolts are arranged on the two sides of the two reinforcing pieces in an embedded mode, and the clamping boltsare tightly attached to one sides of the binding belts; each supporting plate comprises fixing screws, fixing grooves and embedding lines, the plurality of fixing screws are arranged inside each supporting plate in a penetrating mode, the fixing screws are in threaded connection with the supporting plates, and the plurality of fixing grooves are formed in an inner opening of each supporting plate. According to the buffer spring, the spring framework can be well reinforced through the reinforcing pieces of the buffer spring, then the stress capability of the spring framework is enhanced, the deformation of the spring framework in the using process is avoided, the use by people is facilitated, and the fixation work of people can be greatly facilitated through the fixing screws of the bufferspring.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a buffer spring for automobile engine protection. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] In the prior art, there is a patent No. CN201621455299.0 that provides a variable cross-section compression spring. The variable cross-section part has one end face diameter set to be the same as the diameter of the spiral body, and the other end face diameter to be set to Greater than; the spiral body is a helical spring along the axial direction, and its helix angle is; the support ring is ...
