Description

Technical Field

[0001] The utility model relates to the technical field of shaft rods, in particular to a butt-jointed shaft rod. Background Art

[0002] The shaft is a mechanical component that is mostly used in conjunction with bearings and is used to transmit torque. The shaft is made of stainless steel and is generally rod-shaped.

[0003] Authorization announcement number CN109728677A discloses a docking drive shaft, comprising a main body and a head. The head includes a shaft, a gear fixed to one end of the shaft, and a bearing fixed to the other end of the shaft, with a slot provided in the bearing; the main body includes the shaft and a plug provided at one end of the shaft, the plug being able to fit into the slot, and the main body and the head realizing a plug-in connection. The docking drive shaft is segmented and divided into two parts, the main body and the head, based on the position of the bearing. The part above the bearing is the drive shaft head, and the part below the bearing is the drive shaft main body. The head and the main body are connected by a plug-in connection. Because it is a segmented drive shaft, it can automatically adjust when the precision and concentricity are not high during assembly, thereby achieving better motor efficiency. The motor can increase concentricity during operation; due to the improved concentricity, the motor will also reduce noise and increase efficiency during operation.

[0004] The disadvantage of the existing docking drive shaft is that the two shafts can be docked by inserting the plug into the slot, but there is no fixing structure, and the two shafts are easy to loosen and fall off after docking. Therefore, we propose a docking shaft. Summary of the Invention

[0005] The main purpose of the utility model is to provide a docking shaft rod, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A docking shaft rod comprises a first shaft rod, a second shaft rod, a plug-in column and a docking groove, a plug-in column welded at one end of the first shaft rod, a limiting strip welded at equal distances on the outside of the plug-in column, a limiting column welded at equal distances on the end of the first shaft rod located outside the plug-in column, a second shaft rod is provided on one side of the first shaft rod, a docking groove is provided at one end of the second shaft rod close to the first shaft rod, and a limiting groove is provided at equal distances on the end of the second shaft rod located outside the docking groove.

[0008] Furthermore, fixing bolts are equidistantly embedded in the outer side of the second shaft through threaded grooves, one end of the fixing bolt is connected to a side plate by rotation, and one side of the side plate is equidistantly welded with latch teeth. The side plate is located inside the limiting groove, and rotating the fixing bolt can push the side plate to move.

[0009] Furthermore, a key groove is provided at one outer end of the first shaft rod, and a pin rod is welded to one end of the second shaft rod.

[0010] Furthermore, limit slots corresponding to the limit strips are equidistantly provided on the inner side of the docking slot.

[0011] Furthermore, a slot is provided on one side of the limiting column.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the plug-in column is inserted into the docking groove, the multiple limit strips on the outside of the plug-in column are inserted into the multiple limit slots on the inside of the docking groove, so that when the first shaft rod rotates, the second shaft rod can be driven to rotate. At the same time, multiple limit columns are inserted into the limit slots to improve the stability of the first shaft rod and the second shaft rod after docking. The fixing bolts are rotated to push the side plate to move, so that the multiple teeth are inserted into the slots on one side of the limit column, which can fix the first shaft rod and the second shaft rod after docking to prevent them from loosening or falling off.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3As shown, a docking type shaft rod includes a first shaft rod 1, a second shaft rod 2, a plug-in column 3 and a docking groove 4. The plug-in column 3 is welded at one end of the first shaft rod 1, and a limiting clip 10 is welded equidistantly on the outside of the plug-in column 3. The limiting column 5 is welded equidistantly on the end of the first shaft rod 1 located on the outside of the plug-in column 3. The second shaft rod 2 is provided on one side of the first shaft rod 1, and a docking groove 4 is provided at one end of the second shaft rod 2 close to the first shaft rod 1. The limiting groove 6 is equidistantly provided on the end of the second shaft rod 2 located on the outside of the docking groove 4.

[0020] Among them, such as Figure 3 As shown, fixing bolts 7 are equidistantly embedded in the outer side of the second shaft 2 through threaded grooves, and one end of the fixing bolt 7 is connected to a side plate 13 by rotation. A latch tooth 14 is equidistantly welded on one side of the side plate 13. The side plate 13 is located inside the limiting groove 6. The latch tooth 14 on one side of the side plate 13 is inserted into the latch groove 11, so that the latch groove 11 inserted into the limiting groove 6 can be fixed.

[0021] Among them, such as Figure 1 As shown, a keyway 8 is provided at one end of the outer side of the first shaft rod 1, and a pin rod 9 is welded to one end of the second shaft rod 2. The setting of the keyway 8 makes it convenient for personnel to fix one end of the first shaft rod 1 in the equipment through a flat key, and the setting of the pin rod 9 makes it convenient for personnel to fix one end of the second shaft rod 2 in the equipment.

[0022] Among them, such as Figure 3 As shown, the inner side of the docking groove 4 is provided with limit slots 12 corresponding to the limit strips 10 at equal distances. The limit slots 12 are provided to facilitate the insertion of the limit strips 10 on the outer side of the plug-in column 3 into the inner side.

[0023] Among them, such as Figure 2 As shown, a latching slot 11 is provided on one side of the limiting column 5 , and the latching slot 11 is provided to facilitate the insertion of the latching teeth 14 .

[0024] It should be noted that the present invention is a docking type shaft rod. During operation, personnel insert the plug-in column 3 at one end of the first shaft rod 1 into the docking groove 4 at one end of the second shaft rod 2 to dock the first shaft rod 1 and the second shaft rod 2. When the plug-in column 3 is inserted into the docking groove 4, multiple limit clips 10 on the outside of the plug-in column 3 are inserted into multiple limit clips 12 on the inside of the docking groove 4, so that when the first shaft rod 1 rotates, the second shaft rod 2 can be driven to rotate. At the same time, when the plug-in column 3 is inserted into the docking groove 4, multiple limit columns 5 are inserted into the limit groove 6 to improve the stability of the first shaft rod 1 and the second shaft rod 2 after docking. Personnel use tools to rotate the fixing bolt 7, and the fixing bolt 7 rotates to push the side plate 13 to move, so that the multiple teeth 14 on one side of the side plate 13 are inserted into the clip groove 11 on the side of the limit column 5, which can fix the first shaft rod 1 and the second shaft rod 2 after docking to prevent them from loosening or falling off.
