SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a pipe expanding device capable of controlling the expansion tension degree.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the pipe expanding device comprises a bottom plate, a top pipe, a mandrel, a handle and a rubber sleeve;
the end part of the handle is provided with a cam;
the rubber sleeve is positioned between the top pipe and the bottom plate;
the handle is positioned above the bottom plate;
the mandrel is in sliding fit with the bottom plate, the rubber sleeve and the top pipe, one end of the mandrel is hinged with the cam, and the other end of the mandrel is provided with a stop block;
the rubber sleeve and the top pipe are positioned between the stop block and the bottom plate.
Further, the wear-resisting plate is arranged between the cam and the bottom plate.
Further, still include the stay tube, the stay tube is connected and communicates with the bottom plate, and the stay tube is located between gum cover and the bottom plate and sees that dabber and stay tube sliding fit.
Furthermore, the supporting tube is detachably connected with the bottom plate.
Furthermore, the bottom plate is provided with a connecting hole.
Furthermore, the handle is provided with anti-skid threads.
Further, the stop block is detachably connected with the mandrel.
Further, the stop block is a nut, and the nut is in threaded connection with the mandrel.
The utility model has the beneficial effects that: compared with the existing pipe expanding device, the pipe expanding device comprises a bottom plate, a top pipe, a mandrel, a handle and a rubber sleeve;
the end part of the handle is provided with a cam;
the rubber sleeve is positioned between the top pipe and the bottom plate;
the handle is positioned above the bottom plate;
the mandrel is in sliding fit with the bottom plate, the rubber sleeve and the top pipe, one end of the mandrel is hinged with the cam, and the other end of the mandrel is provided with a stop block;
the rubber sleeve and the top pipe are positioned between the stop block and the bottom plate.
When the rubber sleeve is used, the rubber sleeve extends into the pipe, the handle is rotated, the mandrel pulls the stop block to move through the lever principle, the rubber sleeve is extruded and deformed, and the rubber sleeve deforms along the radial direction of the mandrel to push the pipe wall to deform. When the cam rotates to different positions, the deformation amount of the rubber sleeve is different, the molded lines of the cam can be used for controlling the force of the expanding tube, and further the deformation amount of the expanding tube is controlled. Before the expansion of the pipe, the rubber sleeve is in a contraction state, so that the pipe can be more conveniently inserted into the rubber sleeve, and the pipe can be expanded at different positions without continuously expanding the pipe.

Detailed Description
The utility model will be further explained with reference to the drawings.
As shown in fig. 1 to 4, the tube expansion device comprises a bottom plate 1, a top tube 4, a mandrel 6, a handle 8 and a rubber sleeve 3;
the end part of the handle 8 is provided with a cam 801, and the molded line of the cam 801 can be selected according to the requirements of the pipe expansion deformation and the pipe expansion force;
the rubber sleeve 3 is positioned between the top pipe 4 and the bottom plate 1;
the handle 8 is positioned above the bottom plate 1;
the mandrel 6 is in sliding fit with the bottom plate 1, the rubber sleeve 3 and the top pipe 4, one end of the mandrel 6 is hinged with the cam 801, and the other end of the mandrel 6 is provided with a stop block 5; the stop block can be a square block, a nut, a baffle plate and other parts and is used for pushing the top pipe 4 to move.
The rubber sleeve 3 and the top pipe 4 are positioned between the stop block 5 and the bottom plate 1.
In order to avoid wear of the base plate 1 when the cam 801 rotates, a wear plate 7 is also included, the wear plate 7 being disposed between the cam 801 and the base plate 1. The wear-resisting plate is made of wear-resisting materials such as rubber and plastics.
