DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a double-rod connecting shaft for machining, comprising:

[0021] Two fixing plates 1, two connecting shafts 2 are arranged in parallel on the two fixing plates 1, the four connecting shafts 2 are all rotatably arranged through the corresponding fixing plates 1, the outer ends of the four connecting shafts 2 are all fixedly provided with hexagonal columns 3, and the outer sides of the four hexagonal columns 3 are all fixedly provided with bolts 4;

[0022] The hexagonal column 3 can facilitate the staff to install the bolt 4 on the machine. Since the connecting shaft 2 and the fixing plate 1 are rotatably arranged, the bolt 4 can be screwed into the corresponding threaded hole on the machine by rotating the hexagonal column 3 with a tool;

[0023] The connecting assembly includes two circular columns 5 and two clamping columns 9. The two circular columns 5 are rotatably arranged at the inner ends of the two connecting shafts 2 on the same side. A gear ring 6 is fixedly arranged on the two circular columns 5. A circular groove 7 is arranged on one side of the circular column 5. Two first clamping teeth 8 are fixedly arranged at the outer end of the inner wall of the circular groove 7.

[0024] Two clamping columns 9 are respectively fixedly arranged at the inner ends of the two connecting shafts 2 on the other side, and two second clamping teeth 10 are fixedly arranged at the outer ends of the two clamping columns 9. The two first clamping teeth 8 are matched with the two second clamping teeth 10. The two first clamping teeth 8 and the two second clamping teeth 10 are arranged symmetrically on the circumference, and the two first clamping teeth 8 and the two second clamping teeth 10 are staggered.

[0025] A mounting assembly is provided between the two gear rings 6, and the mounting assembly includes a mounting plate 11, a top plate 12, a rectangular column 13 and a spring 15. The mounting plate 11 is fixedly provided on the top of one of the fixing plates 1, and the top plate 12 is fixedly provided on the top of the mounting plate 11;

[0026] A limit rod 14 is fixedly arranged on the top of the rectangular column 13, and the limit rod 14 penetrates the top plate 12 and is slidably arranged. A spring 15 is fixedly arranged between the rectangular column 13 and the top plate 12, and the limit rod 14 penetrates the spring 15 and is movably arranged. A limit block is fixedly arranged on the outer end of the limit rod 14, and the limit rod 14 plays a role of limiting the rectangular column 13, and the limit block can prevent the limit rod 14 from being pulled out;

[0027] A plurality of gear teeth 16 are fixedly provided on both sides of the rectangular column 13, and the plurality of gear teeth 16 are meshed and connected with the two gear rings 6. A rectangular block is fixedly provided on the bottom of the rectangular column 13, and a handle 17 is fixedly provided on the other side of the rectangular block, and an anti-slip rubber sleeve is fixedly provided on the handle 17;

[0028] When the staff pulls the handle 17 downward to make the limit block abut against the top plate 12, the first latching tooth 8 and the second latching tooth 10 are arranged in a cross-arrangement. At this time, the second latching tooth 10 can be pushed into the circular groove 7. When the handle 17 is released, the spring 15 drives the rectangular column 13 to move to the uppermost end, and the first latching tooth 8 and the second latching tooth 10 are arranged in a coincidence, so that the second latching tooth 10 can be clamped and the clamping column 9 can be fixed;

[0029] Figure 3 The diagram shows the status before and after installation. The circular column 5 and the clamping column 9 on the left are the status before installation, and the circular column 5 and the clamping column 9 on the right are the status after installation.

[0030] The detailed working process of the utility model is as follows:

[0031] 1. During installation, the staff first installs the four connecting shafts 2 on the corresponding machine through four bolts 4, then aligns the two clamping columns 9 with the corresponding circular grooves 7, and then uses the handle 17 to pull the rectangular column 13 downward to drive a number of gear teeth 16 to move downward, thereby driving the two circular columns 5 to rotate through the two gear rings 6, and the two circular columns 5 drive the corresponding two first clamping teeth 8 to rotate. When the two first clamping teeth 8 intersect with the two second clamping teeth 10, the clamping column 9 and the two second clamping teeth 10 can be clamped into the circular groove 7. At this time, release the handle 17, and the rectangular column 13 is reset under the action of the spring 15. The rectangular column 13 drives the two circular columns 5 to rotate in the opposite direction through a number of gear teeth 16 and the two gear rings 6, so that the first clamping teeth 8 overlap with the second clamping teeth 10. At this time, the corresponding machine is fixed;

[0032] 2. During disassembly, the staff uses the handle 17 to pull the rectangular column 13 downward, driving the two circular columns 5 to rotate, so that the first latching teeth 8 and the second latching teeth 10 are distributed crosswise. At this time, the latching column 9 can be moved outward to separate the corresponding machine.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
