Abstract
The invention provides a method for preventing a spring from being damaged by torsional compression, which belongs to the technical field of mechanical parts and solves the technical problem that the compression distance of the spring can not be limited in the prior art. The method comprises a spring, wherein both ends of the spring are respectively fixedly connected with an upper cover plate and a lower cover plate; a retractable draw rod mechanism is fixedly connected between the upper cover plate and lower cover plate; the draw rod mechanism comprises a locating rod with a cavity; one end of the locating rod is fixedly connected with the lower cover plate, and the other end is flexibly connected with a mobile rod which is inserted into the cavity; one end of the mobile rod away from the end inserted into the cavity is fixedly connected with the upper cover plate; and the length of the locating rod is greater than that of the mobile rod. The compression distance of the spring can be limited, thereby preventing the spring from being damaged by torsional compression and prolonging the service life of the spring. Thus, the spring is applicable to the specific fields in need of compression limiting.
Description
The application is the application number submitted to March 29 2014 applying date is 201410124517.1, and denomination of invention is a kind of divisional application with the Chinese invention patent application of the spring assembly of limit function.
Technical field
The invention belongs to component of machine technical field, relate to the method preventing spring damaged by twist compression, the method specifically adopts a kind of spring assembly with limit function.
Background technique
As everyone knows, spring is a kind of component with flexible compressible and resilience, spring of many uses, nearly all indispensable in all trades and professions of mechanical field.But existing spring does not have compression limit function, namely existing spring one can be pressed onto the end, and when spring is compressed into the limit, is easy to twist, thus causes spring impaired, and in the course of time, namely spring can be scrapped.Especially in some specific field, need to control the compression distance of spring, this just causes existing spring and cannot meet this requirement.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of spring assembly with limit function be provided, solve the compression distance of spring that prior art exists can not be spacing etc. technical problem.
For achieving the above object, present invention employs following technical proposal: a kind of spring assembly with limit function, comprise spring, described both ends of the spring is affixed upper cover plate and lower cover plate respectively, a retractable drag link mechanism is connected with between upper cover plate and lower cover plate, described drag link mechanism comprises the positioning rod with cavity, described positioning rod one end and lower cover plate affixed, the other end is flexibly connected movement rod and movement rod is inserted in cavity, described movement rod is away from the affixed upper cover plate in the one end be inserted in cavity, the length of described positioning rod is greater than the length of movement rod.
Have in the spring assembly of limit function above-mentioned, the cavity inner wall of described positioning rod has guiding groove and this guiding groove runs through the two ends of positioning rod; The outer wall of described movement rod has gib block and this gib block extends to the two ends of movement rod and concordant with the two ends of movement rod, and when movement rod is inserted in the cavity of positioning rod, gib block to be inserted in guiding groove and gib block and guiding groove Spielpassung.
Have in the spring assembly of limit function above-mentioned, described guiding groove has two and shaft axis along positioning rod is symmetrical, and described gib block has two and shaft axis along movement rod is symmetrical.
Compared with prior art, the invention has the advantages that: can carry out spacing to the compression distance of spring, ensure that spring not by the damage of twist compression, extend the working life of spring, also making spring be applied to needs to carry out compressing spacing specific area.
Accompanying drawing explanation
Fig. 1 is the present invention's structural representation in a stretched state;
Fig. 2 is the present invention's structural representation under compression;
Fig. 3 is the radial cross section schematic diagram of movement rod of the present invention;
Fig. 4 is the radial cross section schematic diagram of positioning rod of the present invention.
In figure, spring 1, upper cover plate 21, lower cover plate 22, drag link mechanism 3, cavity 30, positioning rod 31, guiding groove 311, movement rod 32, gib block 321.
Embodiment
As Figure 1-4, a kind of spring assembly with limit function, comprise spring 1, described spring 1 two ends are affixed upper cover plate 21 and lower cover plate 22 respectively, upper cover plate 21 and lower cover plate 22 are solid slabs, centre does not have perforate, a retractable drag link mechanism 3 is connected with between upper cover plate 21 and lower cover plate 22, described drag link mechanism 3 comprises the positioning rod 31 with cavity 30, described positioning rod 31 one end and lower cover plate 22 affixed, affixed mode can be that to be spirally connected also can be welding or riveted joint etc., the other end is flexibly connected movement rod 32 and movement rod 32 is inserted in cavity 30, described movement rod 32 is away from the affixed upper cover plate 21 in the one end be inserted in cavity 30, the length of described positioning rod 31 is greater than the length of movement rod 32, in the present invention, movement rod 32 can telescopic moving back and forth in positioning rod 31, when movement rod 32 is inserted in positioning rod 31 completely, the length of positioning rod 32 is the limiting length of spring assembly compression, also position length is.
Cavity 30 inwall of positioning rod 31 has guiding groove 311 and this guiding groove 311 runs through the two ends of positioning rod 31, the outer wall of described movement rod 32 has gib block 321 and this gib block 321 extends to the two ends of movement rod 32 and concordant with the two ends of movement rod 32, when movement rod 32 is inserted in the cavity 30 of positioning rod 31, gib block 321 to be inserted in guiding groove 311 and gib block 321 and guiding groove 311 Spielpassung, flexible dependence gib block 321 between movement rod 32 and positioning rod 31 plays positioning action with guiding groove 311, thus prevent telescopic process medi-spring 1 from twisting, thus the axis making telescopic process of the present invention be only limited to spring 1 is carried out, thus the flexible more reliable of spring 1 is made.
As the preferred scheme of one, guiding groove 311 has two and shaft axis along positioning rod 31 is symmetrical, described gib block 321 has two and shaft axis along movement rod 32 is symmetrical, two symmetrical guiding grooves 311 make telescopic process more flexibility and reliability with coordinating of gib block 321, and namely the axial stretching of spring 1 is more reliable.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
