Abstract
The utility model discloses a dual-head conjoined tension spring, which comprises spring bodies and shackles, and is characterized in that the tension spring comprises two cylindrical spring bodies; one cylindrical spring body (1) is connected with the other cylindrical spring body (2) through a connection arm (3); a line connecting the center (9) of the shackle (5) at the tail end of the cylindrical spring body (1) with the center (8) at the tail end of the cylindrical spring body (2) is parallel to the connection arm (3); and the shackles are arranged on two sides of outer diameter lines (7) of the cylindrical spring bodies. The utility model has the advantages that flexible installation space of the tension spring is satisfied to a greater extend; the situation of larger distance of work points can be satisfied, thereby avoiding the situations that a commonly used tension spring can not be satisfied well.
Description
Technical field
The utility model relates to a kind of extension spring, especially relates to a kind of extension spring of double end disjunctor.
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, also produced certain prestressing force in the spring thread, after the pulling force that adds was greater than initial tension, each circle just began to separate, and did 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 relatively more negative assorted and the situation that its work distance point is bigger of the structure installing space at the extension spring place that be used, both needed to satisfy the installing space of extension spring, satisfy the bigger situation of work distance point again, extension spring commonly used just can't well be satisfied such state requirement.
The model utility content
Installing space and big work distance point that the utility model can't satisfy extension spring for solving extension spring commonly used are influenced by structural factor and can't use the present situation of common extension spring and the extension spring of a kind of double end disjunctor of providing when the installing space of extension spring intermediate portion especially.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: the extension spring of a kind of double end disjunctor, comprise spring body, shackle, extension spring comprises 2 cylindricality spring bodies, cylindricality spring body links to each other with another cylindricality spring body by link arm, the shackle center of cylindricality spring body end is parallel with link arm with the line of centres that the shackle center of another cylindricality spring body end is linked to be, and is in the both sides of the cylindrical outer diameter line of cylindricality spring body respectively.The problem that common extension spring can't normal mounting when having avoided other structure member being arranged in the middle of the extension spring.
As preferably, shackle exceeds the cylindrical outer diameter line of spring body outside cylindricality spring scapus body.
As preferably, link arm is arranged on the cylindrical outer diameter line of cylindricality spring body, and is in together on the extension spring body cylindrical straight radial line with link arm.Raising to a greater extent the available installing space of extension spring.
The beneficial effects of the utility model are: the flexible installing space that has satisfied extension spring to a greater extent, satisfy the bigger situation of work distance point again, the situation of having avoided extension spring commonly used just can't well satisfy makes full use of the middle link arm of extension spring and the useful space between the shackle line of centres.
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 utility model double end disjunctor extension spring.
Embodiment
Among the embodiment shown in Figure 1, the extension spring of a kind of double end disjunctor, comprise spring body, shackle, extension spring comprises 2 cylindricality spring bodies, cylindricality spring body 1 links to each other by link arm 3 with cylindricality spring body 2, the center 9 of cylindricality spring body 1 loop break 5 is parallel with link arm 3 with the line of centres 10 that the center 8 of the shackle 6 of cylindricality spring body 2 ends is linked to be, and is in the both sides of the cylindrical outer diameter line 7 of spring body respectively.Shackle 4 exceeds the cylindrical outer diameter line 7 of spring body outside cylindricality spring body 1 cylindrical body.Shackle 5 exceeds the cylindrical outer diameter line 7 of spring body outside cylindricality spring body 1 cylindrical body.Link arm 3 is located on the cylindrical outer diameter line of cylindricality spring body, and is in together on the extension spring body cylindrical straight radial line with end 4, terminal 11.
Claims (4)
1. double end disjunctor extension spring, comprise spring body, shackle, it is characterized in that: the spring extension spring comprises 2 cylindricality spring bodies, link arm, cylindricality spring body (1) links to each other by in the middle of the link arm (3) with cylindricality spring body (2), the center (9) of cylindricality spring body (1) loop break (5) is parallel with link arm (3) with the line of centres (10) that the center (8) of the shackle (6) of cylindricality spring body (2) end is linked to be, and is in the both sides of the cylindrical outer diameter line (7) of cylindricality spring body respectively.
2. according to the extension spring of the described double end disjunctor of claim 1, it is characterized in that: described shackle (4) exceeds the cylindrical outer diameter line (7) of spring body outside cylindricality spring body (1) cylindrical body.
3. according to the extension spring of the described double end disjunctor of claim 1, it is characterized in that: described shackle (5) exceeds the cylindrical outer diameter line (7) of spring body outside cylindricality spring body (1) cylindrical body.
4. according to claim 1 or 2 or 3 described double end disjunctor extension springs, it is characterized in that: described link arm (3) is located on the cylindrical outer diameter line of cylindricality spring body, and is in together on the extension spring body cylindrical straight radial line with shackle (4), shackle (5).
