[0027] The present utility model provides a telescopic pipe adjusting device, which includes a support cylinder 101, a workbench 102 and a linkage mechanism. The linkage mechanism includes two connecting rods 115, a bidirectional screw 116, a mounting seat 117, two limiting rings 122 and a knob 123. By the foregoing solution, the technical problem that when adjusting the straightening block 106, it is necessary to rotate a plurality of bolts in sequence, and this adjustment method is time-consuming and laborious, thus reducing the fixing efficiency of the pipe fittings is solved.

[0028] For this specific embodiment, a support rod 103 is slidably arranged in the support cylinder 101. A fixing ring 104 is arranged above the support rod 103. Slide rods 105 are arranged on both sides of the fixing ring 104. One end of each slide rod 105 is provided with a straightening block 106 through a bolt. A heating sheet 107 is arranged in the straightening block 106. The end face of the workbench 102 has a convex groove 108. A convex block 109 is arranged in the convex groove 108. A vertical plate 110 is arranged on the convex block 109. A first motor 111 is arranged on the rear end face of the vertical plate 110. The output end of the first motor 111 is provided with a C-shaped frame 112, and the C-shaped frame 112 is located on the front end face of the vertical plate 110. Two electric telescopic rods 113 are arranged in the C-shaped frame 112. The output end of the electric telescopic rod 113 is provided with a protection pad 114. The support cylinder 101 is fixedly connected to the workbench 102 and is located at one end of the workbench 102 away from the vertical plate 110. The staff first takes the telescopic pipe fitting to be straightened, inserts the fitting into the straightening block 106, and then makes the straightening block 106 fit with the fitting through the linkage mechanism. The heating sheet 107 in the straightening block 106 generates a certain amount of heat to heat the fitting to a certain extent, making the fitting easier to be straightened. Then, one end of the fitting is placed in the C-shaped frame 112, and the electric telescopic rod 113 is started to make the protection pad 114 fix the fitting. The protection pad 114 can prevent the fitting from deforming due to excessive pressure. Then, the movement of the vertical plate 110 makes the C-shaped frame 112 drive the fitting to pass through the straightening block 106. At the same time, the first motor 111 drives the C-shaped frame 112 to rotate, so that the fitting rotates when passing through the straightening block 106, thereby achieving multi-angle straightening adjustment and improving the straightening effect of the fitting.

[0029] Wherein, a threaded sleeve 118 is arranged above the connecting rod 115, a driven gear 119 is arranged in the middle of the bidirectional screw rod 116, an active cavity 120 is arranged in the mounting seat 117, a driving gear 121 is arranged in the active cavity 120, the rotating shaft of the driving gear 121 extends to the outside of the mounting seat 117, the two connecting rods 115 are respectively fixedly connected to the corresponding sliding rods 105 and are located at the other ends of the sliding rods 105, the threaded sleeve 118 is in threaded connection with the bidirectional screw rod 116 and is sleeved on the bidirectional screw rod 116, the bidirectional screw rod 116 is rotationally connected to the mounting seat 117 and penetrates through both ends of the mounting seat 117, the driven gear 119 is meshed with the driving gear 121 and is located in the active cavity 120, the mounting seat 117 is fixedly connected to the fixed ring 104 and is located above the fixed ring 104. By arranging two straightening blocks 106 to clamp the pipe fittings of the telescopic pipe, and then enabling the two straightening blocks 106 to move in a mutually approaching direction through the bidirectional screw rod 116, the need to adjust each straightening block 106 sequentially is avoided, thereby improving the fixing efficiency of the pipe fittings.

[0030] Secondly, two limiting rings 122 are respectively fixedly connected to the bidirectional screw rod 116 and are located at both ends of the bidirectional screw rod 116. The knob 123 is fixedly connected to the driving gear 121 and is located on the rotating shaft of the driving gear 121. The limiting ring 122 can prevent the threaded sleeve 118 from falling off the bidirectional screw rod 116, and the knob 123 can facilitate the rotation of the driving gear 121.

[0031] Thirdly, two bearings 124 are further arranged in the middle of the bidirectional screw rod 116. The two bearings 124 are respectively arranged in the mounting seat 117, and the driven gear 119 is located between the two bearings 124. Two positioning rods 125 are arranged on the rear end face of the straightening block 106. The two positioning rods 125 are respectively slidably connected to the fixed ring 104 and penetrate through the fixed ring 104. The bearings 124 can facilitate improving the stability of the bidirectional screw rod 116 during rotation, and the positioning rods 125 can improve the stability of the straightening block 106 during horizontal movement.

[0032] When using the present utility model to fix the telescopic pipe fitting, by rotating the knob 123, the knob 123 drives the driving gear 121 to rotate. The driven gear 119 rotates under the action of the driving gear 121, thereby driving the bidirectional screw 116 to rotate. The two connecting rods 115 move in a direction approaching each other under the action of the positioning rod 125, and then the two straightening blocks 106 clamp and fix the outer side of the telescopic pipe fitting, thus completing the fixation. In this way, the technical problem that when adjusting the straightening block 106, it is necessary to rotate multiple bolts in sequence, which is time-consuming and laborious, and thus reduces the fixing efficiency of the pipe fitting is solved.
