Description
Technical field
The utility model relates to a kind of spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work, generally makes with spring steel, and its principle under external force deformation occurs, and restores to the original state again after removing external force.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring, heterotypic spring etc.Spring is mechanical and widely used a kind of elastic element in electron trade, wherein Compress Spring is most widely used, the cross section of Compress Spring spring material used mostly is circular, at some special occasions, owing to requiring that installing space limits, the Compress Spring of circular cross-section can not produce enough elastic force in fixing length, cannot meet usage requirement.In addition, existing spring is made up of the spring of an even thickness, and the shortcoming of this spring is: deformation could occur when being only subject to larger power, and by during to less power, spring not deformation, in fact just loses shock-proof effect.Therefore be necessary to improve.Existing whole spring assembly is a loose mail, and spring cannot meet the requirement of stability in the course of the work, may cause operational failure, of long duration, even can cause the injury of permanent type to spring.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, shock-proof effect is good, corresponding deformation effects can be made to strength by the different spring body of thickness, save deformation space and can compression effectiveness be improved, U-shaped structure is adopted to increase the compression volume of spring, long service life, stability is high, solves the spring that existing spring cannot meet the drawback of stability requirement and easily generation unrepairable formula deformation in the course of the work.
For solving the problem, the utility model adopts following technological scheme:
A kind of spring, comprise spring seat, spring body and limit connection device, described spring seat is provided with two, and lay respectively at the two ends up and down of spring body and limit connection device, described spring seat is fixedly connected with spring body and limit connection device respectively, described limit connection device is positioned at the middle part of spring body, described limit connection device is flexibly connected with spring body, long service life, stability is high, solve the drawback that existing spring cannot meet stability requirement in the course of the work and the deformation of unrepairable formula easily occurs, the spring body of described spring body to be cross section be U-shaped, groove is provided with on the upside of described spring body, save deformation space and can compression effectiveness be improved, U-shaped structure is adopted to increase the compression volume of spring, described spring body includes upper spring body and lower spring body, described upper spring body is positioned at the top of lower spring body, and be fixedly connected with lower spring body, the cross section radius of described upper spring body is less than the cross section radius of lower spring body, structure is simple, shock-proof effect is good, corresponding deformation effects can be made to strength by the different spring body of thickness.
As preferably, described spring seat is stainless steel spring seat, sturdy and durable.
As preferably, described spring body is stainless steel spring main body, sturdy and durable.
As preferably, described limit connection device is hydraulic stop connection set, and spacing switching performance is good.
As preferably, described groove is arc groove, utilizes the structure of arc to improve the space of spring-compressed.
As preferably, described spring seat includes upper spring seat and lower spring cup.
The beneficial effects of the utility model are: owing to being provided with the upper spring body and lower spring body that cross section radius size differs, structure is simple, shock-proof effect is good, corresponding deformation effects can be made to strength, because spring body is made up of, when being subject to less power the spring body that two joint thicknesses are different by the different spring body of thickness, thin upper spring body generation deformation, when being subject to more energetically, thick lower spring body generation deformation, therefore shock-proof effect is better; Owing to being provided with the spring body and arc groove that cross section is U-shaped, when spring body generation deformation, the lower end of spring body can obtain larger compression volume by the sinking space of arc groove, save deformation space and can compression effectiveness be improved, adopting U-shaped structure to increase the compression volume of spring; Owing to being provided with hydraulic stop connection set, avoid the separated state of spring by limit connection device and cause the technical problem of the poor stability of spring, the problem that spring is excessively stretched can also be overcome, long service life, stability is high, solves the drawback that existing spring cannot meet stability requirement in the course of the work and the deformation of unrepairable formula easily occurs.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of spring of the utility model.
Fig. 2 is the cross sectional representation of the spring body of a kind of spring of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of spring, comprise spring seat 1, spring body 2 and limit connection device 3, described spring seat 1 is provided with two, and lay respectively at the two ends up and down of spring body 2 and limit connection device 3, described spring seat 1 is fixedly connected with spring body 2 and limit connection device 3 respectively, described limit connection device 3 is positioned at the middle part of spring body 2, described limit connection device 3 is flexibly connected with spring body 2, avoid the separated state of spring by limit connection device 3 and cause the technical problem of the poor stability of spring, the problem that spring is excessively stretched can also be overcome, described spring body 2 for cross section be the spring body 2 of U-shaped, groove 8 is provided with on the upside of described spring body 2, when there is deformation in spring body 2, the lower end of spring body 2 can obtain larger compression volume by the sinking space of arc groove 8, U-shaped structure is adopted to increase the compression volume of spring, described spring body 2 includes upper spring body 6 and lower spring body 7, described upper spring body 6 is positioned at the top of lower spring body 7, and be fixedly connected with lower spring body 7, the cross section radius of described upper spring body 6 is less than the cross section radius of lower spring body 7, because spring body 2 is made up of the spring body that two joint thicknesses are different, when being subject to less power, there is deformation in thin upper spring body 6, when being subject to more energetically, there is deformation in thick lower spring body 7.
