Description
Technical field
The utility model relates to spring art, stability high spring when more particularly, to a kind of stretching.
Background technique
Spring be it is a kind of utilize elasticity come work machine components.The part made of elastic material is sent out under external force
Raw deformation restores to the original state again after removing external force.Spring is to generate power using the deformation of itself or store the machine components of energy,
Major function has control mechanical movement, absorption vibration and impact energy, storage and exports energy as power and as dynamometry
Element etc.., can be there is shortcoming, when applying active force appropriate on spring but when with spring, and making
After firmly removing, spring will recover to reset condition.But the power many times applied on spring is uncontrollable, effect
Power tends to exceed the elastic range of spring itself, so that spring can not restore after being stretched deformation, causes to be permanently deformed, lead
It causes spring that cannot be used again, brings loss.
Utility model content

It is connected with threaded block, one end of connecting rope length direction is provided with protective block, the hole of the through-hole on the threaded block
Diameter is less than the maximum effective diameter of protective block.Spring body is made of at least three bung flange layers, between each bung flange layer from upper and
Under be mutually sequentially connected, be in integral structure, bung flange layer is equipped with the through-hole vertical with each bung flange layer, each logical on each bung flange layer
The hole heart in hole is located along the same line, and connecting rope is slidably connected between each through-hole, and connecting rope can be to glide on opposing through-bores
It is dynamic, it is provided in the connecting rope between adjacent turns layer with externally threaded screw shell, screw shell is fixed in connecting rope,
It is threaded with threaded block on screw shell, the internal thread hole matched with screw shell is provided in threaded block, rotates screw thread
Seat can make threaded block move up and down along connecting rope length direction, and one end on threaded block along connecting rope length direction is provided with
Protective block, the aperture of through-hole are less than the maximum effective diameter of protective block, and spring body stress stretches, when level of stretch is more than spring
After the tolerance range of ontology, most no more than the attainable elasticity of adjacent turns layer institute by the length between adjacent protective block
Big effective length, so when the limit has not been reached yet in the length of spring body, connecting rope stress, the protective block in connecting rope is supported
On corresponding bung flange layer, protective block has blocked the stretching between adjacent turns layer, and the power entirely stretched is born by connecting rope,
It prevents spring body tension stretch excessive and irrecoverable, extends the service life of spring, while can be by rotating screw thread
Seat adjusts the distance between adjacent protective block, so as to adjust the effective tensile elongation of maximum of spring.
Preferably, being evenly arranged with multiple elastomer blocks around connecting rope on the through-hole wall.It is enclosed on through-hole wall
Be evenly arranged with multiple elastomer blocks around connecting rope, elastomer block is made of elastic material, can prevent connecting rope when moving due to
It causes to be lost with spring body friction.
Preferably, the tapered structure of the protective block.The tapered structure of protective block is prevented when spring stress stretches
Protecting block diameter small portion can be caught in corresponding through-hole, and the setting of pyramidal structure plays the role of guiding, be convenient for
Protective block sticks into through-hole.
Preferably, the endurance of the connecting rope is greater than the weight that can bear under spring body maximum effective length
Power.The endurance of connecting rope is greater than the gravity that can bear under spring body maximum effective length, can guarantee spring body not
The deformation that can not be restored can be generated due to by excessive drawing force.
Preferably, the connecting rope is wirerope.Connecting rope is wirerope, and the tension load-bearing capacity of wirerope is strong,
Spring can preferably be protected.
Therefore, the high spring of stability has following advantages: the utility model structure when a kind of stretching of the utility model
Simply, it can prevent spring stress from excessively stretching and lead to spring permanent distortion, and setting by threaded block and screw shell
Meter can adjust the effective tensile elongation of maximum of spring, when the design of elastomer block can prevent connecting rope mobile because with spring
It rubs and generates excessive loss.
Detailed description of the invention
Attached drawing 1 is a kind of structural schematic diagram of the utility model.
Attached drawing 2 is partial sectional view when the utility model stretches.
It illustrates: 1- protective block, 2- threaded block, 3- connecting rope, 4- bung flange layer, 5- spring body, 6- screw shell, 7-
Through-hole, 8- elastomer block.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
