Description
Technical field
The utility model relates to a kind of explosion-proof sealing ring extracting tool of explosion-proof electric equipment, particularly a kind of hand-rail type quick-detachment antiexplosive sealing ring device.
Background technology
The electrical equipment that down-hole adopts is electric apparatus for explosive gas, such as common flame-proof switch, fire-proof motor etc., also very strict to the wiring technological requirement of electric apparatus for explosive atmospheres, require electric apparatus for explosive atmospheres explosion-proof sealing ring can not have damage, permanent deformation, effective dimensions fit clearance are not reached and require not have sealing function, change.Because laminating between antiknock device sealing ring and loudspeaker nozzle internal diameter is tight, be difficult for taking out, in the time of operation, can destroy sealing ring, cause the increase of major hidden danger and material consumption and work efficiency.
Summary of the invention
Defect and the deficiency existing for prior art of the present utility model, providing can quick-detachment explosion-proof sealing ring, and can be by a kind of hand-rail type quick-detachment antiexplosive sealing ring device of the excellent dismounting of explosion-proof sealing ring.
The technical solution of the utility model is: a kind of hand-rail type quick-detachment antiexplosive sealing ring device, comprise thread, described thread one end is threaded with rotating disk, the other end is provided with nut and fixes, on thread between described rotating disk and nut, autorotation disk end starts to be set with successively the solid seat in pressure bearing, top and the baffle plate that slide along thread, and a side of described rotating disk is fixedly connected with handle.
In said structure, the solid seat in described top contains gripper shoe and supporting leg, and described supporting leg is fixed on the two ends of gripper shoe bottom surface, and the distance of two supporting leg inner surfaces is greater than the external diameter of sealing ring.
Further, the vertical face of the solid seat in described top is down " Qian " font.
In said structure, the solid seat in described top is made up of hollow cylindrical shell and the gripper shoe that is fixed on hollow cylindrical shell upper end, and the internal diameter of described hollow cylindrical shell is greater than the external diameter of explosion-proof sealing ring.
The beneficial effects of the utility model are:
The utility model provides a kind of hand-rail type quick-detachment antiexplosive sealing ring device according to the size of explosion-proof sealing ring size in mined flame-proof switch and characteristic spy, this device is by rotating rotating disk process pressure bearing, the solid seat in top, threaded thread through explosion-proof sealing ring, the other end adopts baffle plate and nut to block sealing ring, and turning handle can stand intact sealing ring to exit.Simple in structure, easy to make, safe and reliable, reduce the dismounting explosion-proof sealing ring time, saving of work and time, increases work efficiency, and is easy to promotion and implementation.
Brief description of the drawings
Fig. 1 is one of structural representation of the utility model hand-rail type quick-detachment antiexplosive sealing ring device;
Fig. 2 be the utility model hand-rail type quick-detachment antiexplosive sealing ring device structural representation two.
The meaning of number in the figure representative is: 1, handle, 2, rotating disk, 3, pressure bearing, 4, thread, 5, gripper shoe, 6, supporting leg, 7, baffle plate, 8 nuts, 9, hollow cylindrical shell.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Embodiment 1: referring to Fig. 1, a kind of hand-rail type quick-detachment antiexplosive sealing ring device, comprise thread 4, described thread 4 one end are threaded with rotating disk 2, it is fixing that the other end is provided with nut 8, on thread 4 between described rotating disk 2 and nut 8, autorotation disk 2 ends start to be set with successively the solid seat in pressure bearing 3, top and the baffle plate 7 that slide along thread, and a side of described rotating disk 2 is fixedly connected with handle 1.
In said structure, the solid seat in described top contains gripper shoe 5 and supporting leg 6, and described supporting leg 6 is fixed on the two ends of gripper shoe 5 bottom surfaces, and the distance of two supporting leg inner surfaces is greater than the external diameter of sealing ring.Described gripper shoe can adopt rectangle, square, polygon, circle or elliptical plate.
Further, the vertical face of the solid seat in described top is down " Qian " font.
Embodiment 2: referring to Fig. 2, embodiment 2 is basic identical with embodiment 1 structure, the meaning of number in the figure representative is identical, something in common does not repeat, difference is: the solid seat in described top is made up of hollow cylindrical shell 9 and the gripper shoe that is fixed on hollow cylindrical shell 9 upper ends, and the internal diameter of described hollow cylindrical shell 9 is greater than the external diameter of explosion-proof sealing ring.The cross section of described hollow cylindrical shell 9 is circle, ellipse, square, rectangle, hexagon or octagon.
Using method of the present utility model: thread of the present utility model 4 one end are threaded with the screw being opened on rotating disk 2, on thread 4, be set with pressure bearing 3 again, by pressure transmission, pulling capacity is reached to explosion-proof sealing ring, then the solid seat in top is installed, the solid seat in top can be selected according to the size of explosive-proof sealed loop diameter, then thread 4 is penetrated to explosion-proof sealing ring, pass the thread 4 end suit overhead gages 7 of explosion-proof sealing ring, adopt nut 8 to be fixed, by rotating rotating disk 1 squeeze pressure bearing, thread 4 can very light exit sealing ring, and can ensure that sealing ring is excellent, cut the waste, save cost, saving of work and time.
Above detailed description of the invention is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improve, within all should being included in protection domain of the present utility model.
