In figure: 1 be FFKM for cylindrical sleeves, 2 is half stepped hole, 3,4 be flange, 5 be latch, 6 be left limit projection, 7 be right limit projection, 8 be handle, 9 be spring, 10 be work rest frame, 11 for work rest spacing hole.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the utility model is further described.
As shown in figs 1 to 6, a kind of safety caging device, comprising:
Cylindrical sleeves 1, its inside offers half stepped hole 2, upper end is provided with flange 4, and half stepped hole 2 makes cylindrical sleeves 1 inside in half stepped, and each protrusion of front-back, is respectively upper limit position and lower position;
Latch 5, in its half stepped hole 2 inserting cylindrical sleeves 1 and bottom is provided with for limit bolt 5 at the upper limit position of cylindrical sleeves 1 and the left limit projection 6 of lower position and right limit projection 7;
And, spring 9, its one end is fixed on latch 5, the other end is fixed on the flange 4 of cylindrical sleeves 1;
Described cylindrical sleeves 1, latch 5 and spring 9 is an overall structure.
Design like this, structure is simple, design science, easy to use, integrally cooperatively interact spacing by cylindrical sleeves, latch and spring assembly, can be spacing in go-cart safely and reliably by travelling workpiece frame, the safety of effective guarantee staff and the quality of product.In addition, cylindrical sleeves upper end has that flange is fixing can not come off, and fail safe is higher.In addition, in order to uniform force, be provided with bottom latch and left and right a guide vane end stop is respectively set, be respectively left limit projection and right limit projection.
Concrete, external diameter and the work rest endoporus contact position of described cylindrical sleeves 1 are provided with FFKM 3, and this FFKM 3 can bear 316 degree.Design like this, reduces stress surface stress and concentrates, prevent product from being shaken because of relative motion, protects sleeve and work rest endoporus because of motion pulling force simultaneously and produces permanent expendable mechanical damage.
Concrete, described latch 5 upper end is provided with handle 8, and is processed into one end and is threaded and screws, detachably.Design like this, is convenient for changing spring.
