Specific embodiment
The utility model is described in further detail below with reference to embodiment, following embodiment is to the utility model
Explanation and the utility model is not limited to following embodiment.
Embodiment 1:
As shown in Figure 1, the present embodiment is made of leading portion spring 1, back segment spring 2 and clamping close device 3, wherein leading portion spring 1
Rear end continue to extend outward the interior interconnecting piece 11 being made of continuous circular shape, the outer diameter setting of interior interconnecting piece 11 is less than leading portion bullet
The internal diameter of 1 main body of spring, wherein the internal diameter half that the outer diameter of interior interconnecting piece 11 is set as 1 main body of leading portion spring is excellent；Back segment spring 2
Front end continue to extend inwardly interconnecting piece 21 outside the outer interconnecting piece formed be close to by continuous circular shape, outer 21 outer diameter of interconnecting piece it is small
In the internal diameter of 2 main body of leading portion spring 1 and back segment spring, and be slightly larger than interior interconnecting piece 11 outer diameter, in addition 21 internal diameter of interconnecting piece with
Essentially identical interior 11 outer diameter of interconnecting piece is excellent.Clamping close device 3 is by front limit part 31, rear locating part 32 and four 33 groups of connector
At wherein connector 33 can select copper sheet or iron plate, and the thickness of connector 33 selected according to the thickness of spring, connection
33 both ends of part are provided with U-shaped hook pawl 331, and the structure of front limit part 31 and rear locating part 32 is intermediate slightly convex disk body, disk
Internal side offers hook groove 34 (Fig. 3) and hook 331 cooperates.
Fig. 2 and Fig. 3 is the schematic diagram of interior interconnecting piece 11 and outer interconnecting piece 21, wherein leading portion spring 1 and back segment bullet is omitted
When the main part of spring 2, leading portion spring 1 and back segment spring 2 connect, first interior interconnecting piece 11 is inserted into outer interconnecting piece 21, for
The spring of relatively thin (intensity is smaller), the two can be such that the two cooperates by way of spinning, and for the bullet compared with thick (intensity is larger)
Interior interconnecting piece 11, then can be by being inserted by spring again after expanding its internal diameter after the outer interconnecting piece 21 of heating, and interior interconnecting piece 11 is inserted into
Afterwards in order to outer 21 snug fit of interconnecting piece, can use two ways, it is a kind of as shown in figure 3, interior interconnecting piece 11 annular
It is by snug fit and than outer interconnecting piece 21 with bigger tilt angle, but for the snug fit of the two wall, it is above-mentioned
For differential seat angle no more than 1 °, which is relatively more suitable for thinner small spring, and interior interconnecting piece 11 has higher structure
Intensity；Another way is being not shown in the figure, and has certain interval, tilt angle between the annular and annular of interior interconnecting piece 11
It is identical as outer interconnecting piece 21, to can just accommodate an interior interconnecting piece 11 between making two adjacent 21 annulars of outer interconnecting piece
Annular, the fit system are relatively more suitable for thicker large spring, and interior interconnecting piece 11 and outer 21 fitting area of interconnecting piece are bigger, whole
The tensile property of body is more preferable.After interior interconnecting piece 11 is connect with outer interconnecting piece 21, first connector 33 is connect with rear locating part 32
Afterwards, it is put into back segment spring 2 and is bonded with outer interconnecting piece 21 close to one end of 2 main body of back segment spring, then front limit part 31 is put into
It is bonded with interior interconnecting piece 11 close to one end of 1 main body of leading portion spring in leading portion spring 1, when fitting, due to having at front limit part 31
Certain aduncate space sees that the top and the bottom at front limit part 31 and outer 21 cooperation of interconnecting piece Fig. 3 have gap, thus
Connector 33 can be by can smoothly enter into hook groove 34 close to the part of hook 331 after slight elastic deformation.Further, since leading portion spring
There is the part of connection between 1 and interior interconnecting piece 11, between back segment spring 2 and outer interconnecting piece 21, which may influence front limit part
31, rear locating part 32 is bonded with interior 11 end of interconnecting piece, 21 end of outer interconnecting piece respectively, therefore can be in front limit part 31, rear limit
Setting is open (not shown) to accommodate the part of above-mentioned connection on the part 32 of position, which can be according to actual use situation
It is arranged, details are not described herein.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different.All equivalent or simple changes done according to structure, feature and principle described in the concept of the patent of the utility model,
It is included in the protection scope of the utility model patent.Those skilled in the art of the present invention can be to being retouched
The specific embodiment stated does various modifications or additions or is substituted in a similar manner, without departing from the utility model
Structure or beyond the scope defined by this claim, all should belong to the protection range of the utility model.
