[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2 A pipe socket welding portable rack comprises a main support plate 1, and sheet metal feet 8 are installed on both sides below the main support plate 1. The sheet metal feet 8 can place the rack on the construction site.

[0020] Two parallel optical axes 2 are arranged on the main support plate 1 , and an adjustable tube clamping mechanism and a movable tube clamping mechanism are arranged on the optical axes 2 .

[0021] The adjustable tube clamping mechanism includes an adjusting block 3 sliding on the two optical axes 2. The adjusting block 3 moves on the two optical axes 2 to ensure the stability of its sliding. A through hole is provided on the side wall of the adjusting block 3. A nut seat 9 is provided in the through hole. A screw 10 is connected to the nut seat 9. The screw 10 is threadedly connected to the nut seat 9. The head end of the screw 10 can be against one of the optical axes 2, that is, the axial extension line of the screw 10 intersects with the optical axis 2. Rotating the screw 10 can make the head end of the screw 10 contact the optical axis 2. After tightening, the position of the adjusting block 3 is restricted. After loosening, that is, the head end of the screw 10 leaves the surface of the optical axis 2, then the adjusting block 3 can move. In order to facilitate the user to control the rotation of the screw 10, a plum blossom handle 11 is provided at the tail end of the screw 10.

[0022] The movable tube clamping mechanism includes a gear block 4, a sliding block 5 and a gear shaft 6. The sliding block 5 slides on the two optical axes 2. The bottom of the gear block 4 is fixed on the main support plate 1. The position of the gear block 4 is restricted and it will not move. One end of the gear shaft 6 is fixedly connected to the sliding block 5, and the other end passes through the jack of the gear block 4. The gear shaft 6 is set between the two optical axes 2. Therefore, as long as the gear shaft 6 is driven to move, the sliding block 5 will move on the optical axis 2.

[0023] A gear shaft 7 passes through the gear block 4, and the gear shaft 7 is vertically arranged with the gear shaft 6. A gear structure is arranged on the gear shaft 7, and the gear structure is meshed with the gear shaft 6. Under the action of the rotation of the gear shaft 7, the gear shaft 6 can be driven to move. In order to ensure the rotation stability of the gear shaft 7, copper sleeves are arranged in two through holes on the gear block 4, and the two copper sleeves are sleeved on the outside of the gear shaft 7. A rocking plate 12 is arranged at the terminal of the gear shaft 7, and a crank handle 13 is arranged on the rocking plate 12. The user rotates the gear shaft 7 by turning the rocking plate 12.

[0024] When the sliding block 5 is at the farthest distance from the gear block 4, the head end of the gear shaft 6 still passes through the insertion hole of the gear block 4, so that the gear shaft 7 can drive the gear shaft 6 to move no matter how it rotates, mainly to prevent the sliding block 5 from sliding to the farthest distance, the gear shaft 7 and the gear shaft 6 from disengaging, and then unable to operate normally.

[0025] A first tube clamping assembly is arranged above the adjusting block 3, a second tube clamping assembly is arranged above the gear block 4, and a third tube clamping assembly is arranged above the sliding block 5. The first tube clamping assembly, the second tube clamping assembly and the third tube clamping assembly all include a guide groove body 14, a forward and reverse screw rod 15 is arranged in the groove of the guide groove body 14, a left clamping plate seat 16 is arranged on the left-handed screw thread of the forward and reverse screw rod 15, and a right clamping plate seat 17 is arranged on the right-handed screw thread of the forward and reverse screw rod. Threaded through holes are arranged on the left clamping plate seat 16 and the right clamping plate seat 17, and are threadedly connected with the forward and reverse screw rod 15. As long as the forward and reverse screw rod 15 is rotated, the left clamping plate seat 16 and the right clamping plate seat 17 can move toward each other or move away from each other. When moving toward each other, they can clamp the pipe, and when moving away from each other, they can loosen the pipe.

[0026] A baffle 18 is provided on the side of each guide groove body 14, and the baffle 18 limits the left clamping plate seat 16 or the right clamping plate seat 17. The left clamping plate seat 16 and the right clamping plate seat 17 are symmetrically arranged at the center position of the positive and negative screw rods 15. The left clamping plate seat 16 and the right clamping plate seat 17 move the same distance. Therefore, as long as the baffle 18 limits the left clamping plate seat 16 or the right clamping plate seat 17 at one place, normal operation can be guaranteed.

[0027] A handle 19 is provided at the terminal end of the forward and reverse screw rod 15 passing through the baffle 18 . The setting of the handle 19 can facilitate the user to rotate the forward and reverse screw rod 15 .

[0028] A concentric hole 20 is also formed on the adjusting block 3. The portion of the gear shaft 6 passing through the outside of the gear block 4 adopts a conical structure, which is concentrically aligned with the concentric hole 20. Due to the movement of the gear shaft 6, the setting of the concentric hole 20 can increase the movement stroke of the gear shaft 6.

[0029] Working principle: the first tube clamping assembly is used to clamp one tube, the second tube clamping assembly and the third tube clamping assembly are used to clamp another tube. The hot-melt welding position of the two tubes is between the adjusting block 3 and the gear block 4. By rotating the handle 19, the clamping plate seat 16 and the right clamping plate seat 17 move toward each other, so that the first tube clamping assembly, the second tube clamping assembly and the third tube clamping assembly all clamp the corresponding tubes. When the distance between the welding surfaces of the two tubes is too large, the adjusting block 3 can be moved. After reaching the appropriate position, the plum blossom handle 11 is rotated to make the head end of the screw 10 contact the surface of the optical axis 2 and tighten it. At this time, the adjusting block 3 does not move, and then the welding surfaces of the two tubes are hot-melted. After hot-melting, the rocking plate 12 is rotated. The rotation of the rocking plate 12 drives the gear shaft 7 to rotate, and the gear structure on the gear shaft 7 drives the gear shaft 6 to move. The movement of the gear shaft 6 can drive the movement of the sliding block 5, and the tube moves with the movement of the sliding block 5 until the hot-melt surfaces of the two tubes are connected.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
