DETAILED DESCRIPTION

[0026] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Embodiment 1 of the utility model discloses a connecting rod shaft structure for a filter press.

[0028] Reference Figure 1-Figure 3 A connecting rod shaft structure for a filter press includes an output shaft 1 and a connecting shaft 2. The end of the output shaft 1 close to the connecting shaft 2 is a connecting male head 11, and the end of the connecting shaft 2 close to the output shaft 1 is a connecting female head 21. The connecting male head 11 and the connecting female head 21 are connected to each other and the two are mutually in conflict. The shape and structure of the connecting male head 11 and the connecting female head 21 are not limited. Here, as long as the concentricity of the connection is ensured, and the connection is mutually in conflict, and the shape and structure with a certain overlap part are all acceptable, such as Figure 3 By matching the male connector 11 with the female connector 21, it is ensured that the output shaft 1 and the connecting shaft 2 have a high degree of concentricity when connected.

[0029] The connection between the output shaft 1 and the connecting shaft 2 is sleeved with a connecting sleeve 3, and the connecting male head 11 and the connecting female head 21 are both placed in the connecting sleeve 3. The internal aperture size of the connecting sleeve 3 matches the shape and size of the combination of the connecting male head 11 and the connecting female head 21. Through the combination of the three, the concentricity of the output shaft 1 and the connecting shaft 2 is further guaranteed. The output shaft 1 and the connecting shaft 2 on both sides are connected together through the connecting sleeve 3 to ensure that the two ends are concentric, meet the use standards, increase durability, reduce the time of parking for maintenance, ensure the continuity of process production, and thus reduce the loss of materials.

[0030] Reference Figure 2-Figure 3 The connecting sleeve 3 is provided with a locking device 4, which passes through the overlapping part of the connecting male head 11 and the connecting female head 21, and locks the connecting male head 11 and the connecting female head 21 on the connecting sleeve 3. The locking device 4 plays a role in further fixing and locking the output shaft 1 and the connecting shaft 2, further improving the continuity of the equipment during operation.

[0031] The locking device 4 can be in many forms, and the locking device 4 here is a locking bolt 4, and the locking bolt 41 passes through the connection sleeve 3, and the locking bolt 41 passes through the overlapping part of the connection male head 11 and the connection female head 21 in sequence, and a locking nut 42 is threadedly connected to the locking bolt 41, and the locking nut 42 cooperates with the locking bolt 41 to be locked on the connection sleeve 3. The operator first passes the locking bolt 41 through the connection sleeve 3, the connection male head 11, and the connection female head 21 in sequence, and then tightens the locking nut 42 on the locking bolt 41 until the locking nut 42 is tightly against the connection sleeve 3.

[0032] An anti-loosening washer 44 is placed between the anti-loosening nut 43 and the locking nut 42, and the anti-loosening nut 43 is also threadedly connected to the locking nut 42. Both the anti-loosening nut 43 and the anti-loosening washer 44 have an anti-loosening effect, preventing the locking nut 42 from loosening from the locking bolt 41, further improving the continuity of the equipment during operation.

[0033] Embodiment 2 of the utility model discloses a connecting rod shaft structure for a filter press.

[0034] The difference between the second embodiment and the first embodiment lies in the different forms of the locking device 4 . The second embodiment provides another feasible locking device 4 .

[0035] Reference Figure 4-Figure 7 The locking device 4 includes a locking pin 45, and a locking hole 46 matching the shape of the locking pin 45 is formed through the connecting sleeve 3. Figure 7 As shown, the male connector 11 and the female connector 21 are both provided with a locking groove 47 that matches the shape of the locking pin 45, and the locking pin 45 is placed in the locking hole 46 and the locking groove 47. When the operator sequentially connects the male connector 11 and the female connector 21, and puts the connecting sleeve 3 on the connecting position of the male connector 11 and the female connector 21, the connecting sleeve 3 is rotated to align the locking hole 46 with the locking groove 47, and then the locking pin 45 is installed in the locking groove 47 and the locking hole 46, and the connecting sleeve 3 is locked and limited by the locking pin 45.

[0036] The connecting sleeve 3 is further provided with a retaining spring 48, which is arranged to abut against the locking pin 45. A limiting groove 49 is arranged around the connecting sleeve 3, and the limiting groove 49 passes through the locking hole 46, and the retaining spring 48 is placed in the limiting groove 49. The operator uses the retaining spring 48 in conjunction with the limiting groove 49 through the installation and setting of the retaining spring 48, which further achieves the effect of limiting and clamping, and further improves the continuity of the equipment during operation.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
