In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of rear loading type and renovates stealthy spring turning device, comprise turn over the end and be arranged at described in turn over upper at the end, down turnover cover, the described cross section that turns over the end is L shaped, the middle part of its vertical edge left surface is fixed with a horizontal part, the easy on and off end of its vertical edge is bent to form left, lower rib, on described, between lower rib and described horizontal part, be vertically placed with spring leaf, the free end of described horizontal part respectively upwards below be bent to form vertical upper, lower bending edge, on described, the free end of lower bending edge is columniform rotating shaft, on described, down turnover cover is arc, on described, the left part of down turnover cover has the groove that cross section is circular arc, described rotating shaft is inserted in described groove, the A/F of described groove is greater than the diameter of described rotating shaft, on described, the free end of down turnover cover left part is resisted against on described spring leaf, described rotating shaft is to right-hand bending, described rotating shaft and described spring leaf form prevent described on, down turnover cover is the stopping means of upset excessively, on the bottom surface of described horizontal sides of turning over the end, be fixed with two projections that left and right is arranged.
Renovate in stealthy spring turning device at above-mentioned rear loading type, described in turn on the bottom surface of horizontal sides at the end and be fixed with side by side left and right quarter bend folding part, described projection is positioned at the free-ended top of described left and right quarter bend folding part.
Renovate in stealthy spring turning device at above-mentioned rear loading type, the overbending direction of described left and right quarter bend folding part is relative.
The rear loading type that the utility model provides is renovated stealthy spring turning device can easily increase spring leaf by rotating shaft and groove after improving, and renovates in the time of open mode and can not come off from turning over the end.
Brief description of the drawings
The rear loading type that Fig. 1 provides for the utility model is renovated the cross-sectional structure schematic diagram of stealthy spring turning device.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the rear loading type that the utility model provides is renovated stealthy spring turning device and is comprised turning over the end 1 and being arranged at and turn over upper and lower at the end 1 and renovate 21,22.
The cross section that turns over the end 1 is L shaped, the middle part of its vertical edge 11 left surfaces is fixed with a horizontal part 12, the easy on and off end of its vertical edge 11 is bent to form upper and lower rib 111,112 left, between upper and lower rib 111,112 and horizontal part 12, be vertically placed with spring leaf 3,3 barrier effects of 111,112 pairs of spring leafs of upper and lower rib.
The free end of horizontal part 12 respectively upwards below be bent to form vertical upper and lower bending edge 13,14, the free end of upper and lower bending edge 13,14 is columniform rotating shaft 15, rotating shaft 15 is to right-hand bending.
Upper and lowerly renovate 21,22 for arc, upper and lower 21,22 the left part renovated has the groove 23 that cross section is circular arc, and rotating shaft 15 is inserted in groove 23.The A/F of groove 23 is greater than the diameter of rotating shaft 15, rotating shaft 15 directly can be inserted in groove 23, so just can first multiple spring leafs 3 be put into and be turned at the end 1, then renovate 21,22 and turn over the end 1 and be assembled together by upper and lower, and can in use increase and decrease at any time spring leaf 3.
The upper and lower free end of renovating 21,22 left parts is resisted against on spring leaf 3, and rotating shaft 15 is to right-hand bending, and rotating shaft 15 and spring leaf 3 form and prevent upper and lower 21,22 stopping means that excessively overturn of renovating.Upturning lid 21 is in the time opening, the contact point of the left end of groove 23 and rotating shaft 15 is first make contact, the contact point of the inwall of the outer wall of rotating shaft 15 and groove 23 is the second contact point, the free end of upturning lid 21 left parts and the contact point of spring leaf 3 are the 3rd contact point, connect first make contact and the second contact point and make extended line, the 3rd contact point should be positioned at the clockwise direction of extended line, now the moment of first make contact and the second contact point pair upturning lid 21 is to closing direction, even if thereby the A/F that has ensured groove 23 is greater than the diameter of rotating shaft 15, upturning lid 21 also can excessively not overturn and come off.
Turn on the bottom surface of horizontal sides 17 at the end 1 and be fixed with side by side left and right quarter bend folding part 18,19, the overbending direction of left and right quarter bend folding part 18,19 is relative.Turn on the bottom surface of horizontal sides at the end 1 and be fixed with two projections 4 that left and right is arranged, projection 4 is positioned at the free-ended top of left and right quarter bend folding part 18,19, projection 4 can be that protruding point can be also protruding arcwall face, can between left and right quarter bend folding part 18,19 and projection 4, punch and tighten up a screw, screw can slippage, in the time that two adjacent turning devices connect, does not need connector, utilize existing plate punching to fix, do the moulding of out-of-plane and cambered surface.
The rear loading type that the utility model provides is renovated stealthy spring turning device can easily increase spring leaf 3 by rotating shaft 15 and groove 23 after improving, and renovates 2 and can not come off from turning over the end 1 in the time of open mode.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
