Abstract
The utility model discloses a permanent magnetic mechanism return spring. The permanent magnetic mechanism return spring comprises a permanent magnet joint, a fixing hole, an installation hole and a return spring. By arranging the installation hole on the permanent magnet joint, the return spring can be conveniently installed and dismounted. The permanent magnetic mechanism return spring has the advantages of advanced technology, simple principle, simple structure, convenient use, low cost, high efficiency, stable performance, strong functions, high efficiency, rapidness, and convenient maintenance. By means of the technical improvement of the return spring parts and also the change of the number of parts, the return spring can be rapidly and conveniently replaced. The cost can be lowered to the minimum. Furthermore, the problems existing in a conventional permanent magnetic mechanism and characterized by high return spring cost, low installation efficiency, large occupation area, product cost increase, increased maintenance cost and inconvenient maintenance are relatively well solved. The permanent magnetic mechanism return spring has excellent application value.
Description
Technical field
The utility model belongs to the permanent magnet motor technical field, relates in particular to a kind of permanent magnet mechanism return spring.
Background technology
Magnetic is the attribute of substance responds magnetic fields.Each material more or less can be by influence of magnetic field.Ferromagnetism is strong, the most well known a kind of magnetic.Owing to have ferromagnetism, magnetite or magnet can produce magnetic field.In addition, paramagnetic substance can trend towards the zone stronger towards magnetic field and move, namely by magnetic field suction; Diamagnetic substance then can trend towards towards magnetic field weak zone and move, and is namely repelled by magnetic field; Also have some materials more complicated relation to be arranged with magnetic field, for example, the character of spin glass, antiferromagnetism etc.External magnetic field is very faint for the impact of Cucumber.
The magnetic attitude of material is relevant with temperature, pressure, external magnetic field etc., and according to the difference of temperature or other parameter, material can demonstrate different magnetic; Permanent-magnet electric mechanism is post load switch core component, and it is to realize that the post load switch is to the key point of heavy current circuit break function; Existing mechanism exists the cost of return spring high, and installation effectiveness is not high, it is large to take volume, thereby causes product cost to increase, and maintenance cost increases, and maintenance is inconvenient.
The utility model content
The purpose of this utility model is to utilize a kind of permanent magnet mechanism return spring, be intended to solve existing permanent magnet mechanism and exist the cost of return spring high, installation effectiveness is not high, it is large to take volume, thereby causes product cost to increase, maintenance cost increases, and the inconvenient problem of maintenance.
The purpose of this utility model is to provide a kind of permanent magnet mechanism return spring, and described permanent magnet mechanism return spring comprises permanent magnetism joint, fixing hole, installing hole, return spring; One end of described permanent magnet mechanism arranges described fixing hole, and the other end arranges described installing hole, and an end of described return spring is arranged in the described installing hole, and the other end is connected with described permanent magnet mechanism, and described return spring connects described permanent magnetism joint.
Further, described return spring connects the permanent magnetism joint by installing hole.
Further, the described return spring SWPA that to adopt the firm line 0.7 of qin be steel wire diameter makes.
The permanent magnet mechanism return spring that the utility model provides, by at the permanent magnetism joint installing hole being set, be convenient to the installation and removal of return spring, the SWPA that it is steel wire diameter that return spring adopts the firm line 0.7 of qin makes, the utility model technique is advanced, principle is simple, and simple structure is easy to use, cost is low, efficient is high, and stable performance is powerful, fast efficient, easy to maintenance, by the technological improvement to the return spring parts, and the increase and decrease of parts can be changed return spring quickly and easily, reduced to greatest extent cost, in addition, the utility model preferably resolves existing permanent magnet mechanism and exists the cost of return spring high, and installation effectiveness is not high, it is large to take volume, thereby cause product cost to increase, maintenance cost increases, and the inconvenient problem of maintenance, and good using value is arranged.
Description of drawings
Fig. 1 is the structural representation of the permanent magnetism joint that provides of the utility model embodiment;
Fig. 2 is the structural representation of the return spring that provides of the utility model embodiment.
Among the figure: 1, permanent magnetism joint; 2, fixing hole; 3, installing hole; 4, return spring.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of permanent magnet mechanism return spring, and this permanent magnet mechanism return spring comprises permanent magnetism joint, fixing hole, installing hole, return spring; One end of permanent magnet mechanism arranges fixing hole, and the other end arranges installing hole, and an end of return spring is arranged in the installing hole, and the other end is connected with permanent magnet mechanism, and return spring connects the permanent magnetism joint.
As the prioritization scheme of the utility model embodiment, return spring connects the permanent magnetism joint by installing hole.
As the prioritization scheme of the utility model embodiment, the SWPA that it is steel wire diameter that return spring adopts the firm line 0.7 of qin makes.
Referring to accompanying drawing, the utility model embodiment permanent magnet mechanism return spring is described in further detail.
As depicted in figs. 1 and 2, the permanent magnet mechanism return spring of the utility model embodiment mainly is comprised of permanent magnetism joint 1, fixing hole 2, installing hole 3, return spring 4; One end of permanent magnet mechanism 1 arranges fixing hole 2, the other end arranges installing hole 3, one end of return spring 4 is arranged in the installing hole 3, and the other end is connected with permanent magnet mechanism, and the SWPA that it is steel wire diameter that return spring 4 adopts the firm line 0.7 of qin makes, when needs reset, permanent magnet mechanism resets under the effect of return spring 4, because return spring 4 directly is enclosed within the installing hole 3, is convenient to dismounting and replacing, practicality is also convenient, and parameter and the technical standard of return spring 4 are as shown in the table:
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
