For achieving the above object, the utility model is by the following technical solutions:
A kind of improved reel cage leaf spring pressure structure, include spring block, leaf spring, gripping seat and pin, the head of leaf spring and spring block engagement connection, afterbody and the riveted joint of gripping seat, it is characterized in that: described leaf spring head is one " ten " font structure, the groove engagement connection that its central protrusion and spring block middle part are provided with, the spring block rear end is provided with a supporting pin simultaneously, and the bottom connection of the top of this pin and leaf spring bending part touches.
Also be provided with triangle pressure regulation post between above-mentioned leaf spring head upper surface and the spring block, the eccentric distance of each cylinder from the cylinder center of pressure regulation post has nothing in common with each other, and is provided with regulator hole in the side with the corresponding spring block in pressure regulation post position.
Also be provided with hexagonal pressure regulation post between above-mentioned leaf spring head upper surface and the spring block, the bottom of the pressure regulation post eccentric distance of three cylinders from the cylinder center has nothing in common with each other, the post of pressure regulation column top and on a groove is set, and with the corresponding spring block of this groove location top on a breach is set.
Respectively be provided with a pit on the both sides cylinder of above-mentioned hexagonal pressure regulation column top groove, two pits are used different Paint Daubs respectively.
The leaf spring of the utility model leaf spring pressing mechanism adopts little " ten " font structure broad in the middle in two, meet the Sheet Metal Forming Technology that adds man-hour, the mold tabs position can not occur and collapse the problem fallen, prolonged die life, reduced waste of material, reduce production cost, compared with existing leaf spring structure simultaneously, under the situation of same thickness and width, can obtain bigger pressure.In addition, the spring block rear end is provided with a supporting pin, the bottom connection of the top of this pin and leaf spring bending part touches, it is mainly used in the pulling force that bears leaf spring bending end, thereby make the engaging position be mainly used to the fixed constraint leaf spring, effectively prevent the material deformation at engaging position, prolonged the service life of spring block, ensured the stable of force value.
Leaf spring pressure structure before the triangle pressure regulation rod structure that is provided with between leaf spring and spring block is applicable to is regulated from the pressure regulator hole of reel cage body side surface in use; And hexagonal pressure regulation rod structure be applicable in, back leaf spring pressure structure, regulating mortise with special spanner from spacing of reel cage body top in use stretches into and regulates, transferred force value directly perceived and be easy to observe by making simultaneously, on the both sides cylinder of hexagonal pressure regulation column top groove, respectively be provided with a pit, two pits are used different Paint Daubs respectively, represent different force value.During the utility model has been realized on the basis that does not change existing reel cage body structure, the pressure regulation of back leaf spring pressure structure, three pressure structures form 27 groups of pressure combinations altogether before, during and after making, the pressure adjustable range is expanded as original nine times, and the scope of application is more extensive.
