Abstract
The utility model relates to a kind of pipe fitting dismantling device, specifically a kind of disc type male-pipe dismantling device.Comprise positioning disk, by the screw rod of thread cartridge on positioning disk, the upper end of screw rod is provided with axis hole, the axis of axis hole and the axes normal of screw rod; The lower slide of screw rod is provided with axostylus axostyle, and axostylus axostyle is vertical with screw rod, axostylus axostyle is hinged with first connecting rod and second connecting rod, outer end hinged first gripper shoe and second gripper shoe respectively of first connecting rod and second connecting rod.This tool construction is simple, easy to use, grips pipe fitting from inner chamber, can avoid damaging outer wall during operation.
Description
Technical field
The utility model relates to a kind of pipe fitting dismantling device, specifically a kind of disc type male-pipe dismantling device.
Background technology
When the parts such as the nut on existing dismounting pipe fitting, in order to fixed fitting, generally adopt the instrument such as spanner, pipe wrench, these instruments mostly exert a force at the outer wall of pipe fitting, when outer surface of pipe fittings entire body screw thread or when having other frangible portions, spanner, pipe wrench clamping body is adopted easily to cause screw thread to damage.
Summary of the invention
The utility model provides the disc type male-pipe dismantling device that a kind of structure is simple, easy to use, clamp from inner chamber, avoid outer wall to damage for solving the problem.
The technical scheme that the utility model adopts for technical solution problem is:
Disc type male-pipe dismantling device described in the utility model comprises positioning disk, by the screw rod of thread cartridge on positioning disk, the upper end of described screw rod is provided with axis hole, the axis of described axis hole and the axes normal of screw rod; The lower slide of described screw rod is provided with axostylus axostyle, and described axostylus axostyle is vertical with screw rod, described axostylus axostyle is hinged with first connecting rod and second connecting rod, outer end hinged first gripper shoe and second gripper shoe respectively of described first connecting rod and second connecting rod.
The upper surface of described positioning disk is installed with positioning chuck, and described positioning chuck and positioning disk are coaxially arranged, and the center of positioning chuck is greater than the screw rod installing hole of outer screw diameter with diameter, and the outline of positioning chuck is regular polygon structure.
Described positioning disk is regular polygon structure.
Owing to have employed said structure, this tool construction is simple, easy to use, grips pipe fitting from inner chamber, can avoid damaging outer wall during operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the practical state of the utility model embodiment.
Fig. 2 is the top view of positioning disk and positioning chuck.
Detailed description of the invention
As shown in Figure 1, disc type male-pipe dismantling device described in the utility model comprises positioning disk 1, by the screw rod 2 of thread cartridge on positioning disk 1, the upper end of described screw rod 2 is provided with axis hole 3, the axis of described axis hole 3 and the axes normal of screw rod 2, axis hole 3 can directly on screw rod 2 boring formed, also can in the top of screw rod 2 welding one with the pipe fitting of axis hole or ring set; The lower slide of described screw rod 2 is provided with axostylus axostyle 4, with the installing hole longitudinally arranged on the axostylus axostyle 4 of horizontally set, the lower end of screw rod 2 is inserted in the installing hole on axostylus axostyle 4, and can rotate freely, screw rod 2 bottom, the partial fixing of axostylus axostyle less than 4 connects a plug, the external diameter of plug is greater than the diameter of installing hole on axostylus axostyle 4, prevents screw rod 2 from coming off from installing hole.Described axostylus axostyle 4 is vertical with screw rod 2, described axostylus axostyle 4 is hinged with first connecting rod 5 and second connecting rod 6, outer end hinged first gripper shoe 7 and second gripper shoe 8 respectively of described first connecting rod 5 and second connecting rod 6.
As shown in Figure 2, the upper surface of described positioning disk 1 is installed with positioning chuck 11, described positioning chuck 11 is coaxially arranged with positioning disk 1, and the center of positioning chuck 11 is greater than the screw rod installing hole of screw rod 2 external diameter with diameter, the outline of positioning chuck 11 is regular polygon structure.By instruments such as spanners, positioning disk 1 and positioning chuck 11 can be fixed like this.
Certainly, positioning disk 1 also can be made for regular polygon structure.The use of the instruments such as convenient wrench.
During use, the parts such as the lower end of screw rod 2 and gripper shoe are put in the inner chamber of male-pipe 12, iron rod is injected axis hole 3 rotary screw 2, make axostylus axostyle 4 up, promote the first gripper shoe 7 and the second gripper shoe 8 is expanded to both sides, thus the inwall of itself and male-pipe 12 is combined closely, now with spanner, binding nut 12 is relative with positioning chuck 11 respectively rotates, and can realize the charge and discharge operations of nut 12.
