Abstract
The utility model discloses a long-arm tension spring which comprises a spring body and shackles. one end of a cylindrical spring body (1) of the tension spring is connected with a shackle (7); a straight arm (4) is arranged at the tail of the other end of the cylindrical spring body (1); the straight arm (4) is connected with a slanting arm (3); the slanting arm (3) is connected with a straight arm (5); the tail end of the straight arm (4) is connected with a shackle (6); the straight arm (4) is arranged on the extension line of an outer diameter line (12) of the cylindrical spring body (1); the straight arm (5) is arranged on the extension line of the extension outer diameter line of an outer diameter line (11) of the cylindrical spring body (1); and both the outer diameter line (11) and an outer diameter line (12) are the outer diameter lines on the cylindrical diameter line of the cylindrical spring body (1). Further, the utility model has the advantages that the tension spring can be installed and used effectively in the installation and working environments such as small installation space and long distance of working points.
Description
Technical field
The utility model relates to a kind of extension spring, and especially a kind of use is big at work distance point, the narrower and small long-armed extension spring of installing space.
Background technique
The purposes of spring is very wide, almost is the indispensable element of common mechanical, does the time spent when it is subjected to external force, promptly produces resiliently deformable, thereby has stored strain energy and disengaging at random.Extension spring in the spring kind is the helical spring that bears axial tension, and extension spring is generally all used the circular section made; When cylindroid helicalcoil extension spring was unloaded, each enclosed spiral ring or pitch circle that coiled is close to mutually, outwards extends when being subjected to external force, maintains the power to the centre contraction.Do not bearing when load, generally between the circle of extension spring and the circle all be and tight very close to each other; Extension spring is for the ease of connection, set and loading, and two ends are shaped on the spring hook.In addition, in order to save axial working space, and guarantee that spring each circle when zero load compresses mutually, in the process of reeling of being everlasting, spring thread is reversed around the axis generation of itself, the spring of making like this, each circle promptly has certain impacting force each other, has also produced certain prestressing force in the spring thread, after the pulling force that adds is greater than initial tension, each circle just begins to separate, and does not save axial working space so can there be prestressed extension spring.Can save certain working space and installing space although it is so, but under the situation that the structure installing space is narrower and small and its work distance point is bigger at the extension spring place that is used, extension spring commonly used just can't well be satisfied such state requirement.
The model utility content
It is smaller that the extension spring that the utility model ought be used for solution is in installing space, and under the bigger situation of its work distance point, extension spring commonly used can't can be good at satisfying the actual present situation that requires and provide a kind of can satisfy work distance point greatly, the long-armed extension spring used in the narrower and small state of installing space.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: long-armed extension spring, comprise spring body, shackle, cylindricality spring body one end of extension spring is connected with shackle, the other end end of cylindricality spring body is provided with straight-arm, straight-arm connects oblique arm, oblique arm connects an other straight-arm, the end of an other straight-arm is connected with another shackle, straight-arm is located on the outer radial line line stretcher of cylindricality spring body, an other straight-arm is located on the outer radial line line stretcher of extension of the external radial line of cylindricality spring, and two outer radial lines are the outer radial line on the cylindricality diameter line of cylindricality spring body.For narrow and small at installing space, the occasion that work distance point is big provides convenient effective long-armed extension spring structure.
As preferably, as preferably, the length of straight-arm that connects spring body one end is greater than the length of an other straight-arm.
As preferably, the formed angle A scope of oblique arm and straight-arm is 120～180 degree.
As preferably, shackle is located at outside the cylindrical body circumference of cylindricality spring body.
As preferably, shackle is located at the same side direction of the outer radial line of spring scapus shape.
As preferably, the cylindricality external diameter line parallel of the line of centres of shackle and spring body.
The beneficial effects of the utility model are: further can be narrow and small at installing space for extension spring, provide in the installation that work distance point is big, the working environment and can effectively install and use, simple in structure effective, easy for installation, using scope is wide, uses for the extension spring in the mechanical system to promote bigger space range.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the long-armed extension spring of the utility model.
Embodiment
Among the embodiment shown in Figure 1, long-armed extension spring, comprise spring body, shackle, cylindricality spring body 1 one ends of extension spring are connected with shackle 7, the terminal one-tenth of the other end of cylindricality spring body 1 straight-arm 4, straight-arm 4 connects oblique arm 3, oblique arm 3 connects straight-arm 5, and the end of straight-arm 5 is connected with shackle 6, and straight-arm 4 is located on outer radial line 12 line stretchers of cylindricality spring body 1, straight-arm 5 is located on the outer radial line line stretcher of extension of cylindricality spring body 1 outer radial line 11, and outer radial line 11 and outer radial line 12 are the outer radial line on the cylindricality diameter line of cylindricality spring body 1.The length of straight-arm 4 is 1.5 times of length of straight-arm 5.Oblique arm 3 is 150 degree with straight-arm 4, straight-arm 5 formed angle A.Shackle 6, shackle 7 are located at outside the cylindrical body circumference of cylindricality spring body 1.Shackle 6 and shackle 7 are located at the outer radial line 11 the same side directions of cylindricality of cylindricality spring body 1.Shackle 6 is parallel with the outer radial line 11 of the cylindricality of cylindricality spring body 1 with the line of centres 2 of shackle 7.
When spring used, the distance between shackle 6 and the shackle 7 was bigger, and the step that is provided with of brace has been dwindled the utilized space of installing, when installing space is narrow and small, the parts of shackle 6 clasp joints in small space, shackle also further improves available installing space in the same side of spring body simultaneously.
