[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A chain plate connection structure for a chain plate elevator includes a conveying chain and a chain plate member. A connecting seat is fixedly connected to the outer surface wall of the conveying chain. A fastening rod is screwed and connected to the inner surface wall of the connecting seat. The bottom outer surface wall of the chain plate member is inserted into the top of the connecting seat, and the fastening rod is screwed and connected to the inner surface wall of the chain plate member through a screw hole. A clamping groove is opened on one side of the connecting seat close to the fastening rod, and a limiting component for restricting the loosening of the fastening rod is arranged between the clamping groove and the connecting seat.

[0008] Preferably, the limiting component includes a connecting block and an elastic part for maintaining the position of the connecting block. The outer surface wall of the connecting block is slidably connected to the inner surface wall of the connecting seat through the clamping groove, and a limiting plate is fixedly connected to the open end of the connecting block.

[0009] Preferably, the elastic part includes a matching block slidably connected to the inner surface wall of the connecting seat through a slot, the matching block is rotationally connected to the connecting block through a rotating shaft, and a spring is fixedly connected between the matching block and the inner surface wall of the connecting seat.

[0010] Preferably, a rubber pad is fixedly connected to the inner surface wall of the limiting plate, and the rubber pad abuts against the outer surface wall of the fastening rod.

[0011] Preferably, the front end surface of the limiting plate is provided with a concave portion.

[0012] Preferably, the connecting seat is fixedly connected to the conveying chain via a locking rod, and the top of the locking rod is flush with the inner surface wall of the bottom of the connecting seat.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present application, the connecting seat and the conveying chain are fixed by a locking rod, and the chain plate member is inserted into the top of the connecting seat. At this time, the screw hole on the chain plate member is aligned with the fastening rod on the connecting seat. The fastening rod is rotated to engage with the screw hole, so that the connecting seat and the chain plate member can be fixed. When the chain plate is damaged later, the chain plate can be separated by rotating the locking rod, thereby realizing the independent replacement of the chain plate member and improving the convenience of independent replacement of the chain plate member, thereby improving the convenience of using the chain plate connection structure for the chain plate type elevator.

[0015] 2. In the present application, in the initial state, the limit plate overlaps the outer wall of the connecting seat and is on the side away from the fastening rod. After the connection seat and the chain plate member are fixed by the fastening rod, the limit plate is pulled to drive the connecting block to completely disengage from the slot. Then the limit plate is rotated 180 degrees, and the connecting block rotates and cooperates with the matching block through the rotating shaft. Then the limit plate is released, and the spring pulls back the matching block. The matching block drives the connecting block to re-engage the slot, and the limit plate is stably abutted against the outside of the locking rod. While the locking rod is isolated by the limit plate, the friction force generated by the contact between the limit plate and the locking rod can effectively limit the loosening of the fastening rod, thereby improving the stability of the chain plate connection structure for the chain plate type hoist.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A chain plate connection structure for a chain plate elevator, including a conveyor chain 1 and a chain plate member 2. A connection seat 3 is fixedly connected to the outer surface wall of the conveyor chain 1. A tightening rod 6 is screwed to the inner surface wall of the connection seat 3. The bottom outer surface wall of the chain plate member 2 is inserted into the top of the connection seat 3, and the tightening rod 6 is screwed to the inner surface wall of the chain plate member 2 through a screw hole. A card slot 7 is opened on one side of the connection seat 3 close to the tightening rod 6, and a limiting component for restricting the loosening of the tightening rod 6 is provided between the card slot 7 and the connection seat 3;

[0025] The connection seat 3 and the conveyor chain 1 are fixed through the locking rod 4. When the chain plate member 2 is inserted into the top of the connection seat 3, the screw hole on the chain plate member 2 is exactly aligned with the tightening rod 6 on the connection seat 3. Rotate the tightening rod 6 to make it combine with the screw hole, and the fixation of the connection seat 3 and the chain plate member 2 can be achieved. Subsequently, when the chain plate member 2 is damaged, the separation of the chain plate member 2 can be achieved by rotating the tightening rod 6. In this way, while realizing the independent replacement of the chain plate member 2, the convenience of the independent replacement of the chain plate member 2 is ensured, thereby improving the convenience of use of the chain plate connection structure for the chain plate elevator.

[0026] Specifically, as Figure 2 And Figure 4As shown, the limit assembly includes a connecting block 8 and an elastic part for maintaining the position of the connecting block 8. The outer wall of the connecting block 8 is slidably connected to the inner wall of the connecting seat 3 through the card slot 7. The open end of the connecting block 8 is fixedly connected to the limit plate 5. The elastic part includes a matching block 10 that is slidably connected to the inner wall of the connecting seat 3 through the card slot 7. The matching block 10 and the connecting block 8 are rotatably connected through the rotating shaft 9, and a spring 11 is fixedly connected between the matching block 10 and the inner wall of the connecting seat 3. In the initial state, the limit plate 5 overlaps the outer wall of the connecting seat 3 and is on the side away from the fastening rod 6. When the connection seat is completed by the fastening rod 6, the limit plate 5 is connected to the inner wall of the connecting seat 3. 3 is fixed to the chain plate member 2, the limit plate 5 is pulled to drive the connecting block 8 to completely disengage from the slot 7, and then the limit plate 5 is rotated 180 degrees, and the connecting block 8 is rotated and matched with the matching block 10 through the rotating shaft 9, and then the limit plate 5 is released, and the spring 11 pulls back the matching block 10, and the matching block 10 drives the connecting block 8 to re-engage the slot 7, and the limit plate 5 is stably abutted against the outer side of the fastening rod 6. While the fastening rod 6 is isolated by the limit plate 5, the friction force generated by the contact between the limit plate 5 and the fastening rod 6 can effectively limit the loosening of the fastening rod 6, thereby improving the stability of the chain plate connection structure for the chain plate type hoist.

[0027] Specifically, Figure 2 and Figure 3 As shown, a rubber pad is fixedly connected to the inner wall of the limit plate 5, and the rubber pad abuts against the outer wall of the fastening rod 6, thereby ensuring the stable contact between the limit plate 5 and the fastening rod 6. An inner recess 12 is provided on the front end surface of the limit plate 5, and the area formed thereby can be used as a handle to facilitate the operator to move the limit plate 5. The connecting seat 3 is fixedly connected to the conveying chain 1 through the locking rod 4, and the top of the locking rod 4 is flush with the inner wall of the bottom of the connecting seat 3, thereby ensuring the convenient disassembly and assembly of the connecting seat 3. After the chain plate member 2 is fixed to the connecting seat 3, the bottom of the chain plate member 2 just contacts the locking rod 4, thereby limiting the loosening of the locking rod 4 through the friction generated by the contact.

[0028] Working principle: The connecting seat 3 and the conveyor chain 1 are fixed by the locking rod 4, and the chain plate member 2 is inserted into the top of the connecting seat 3. At this time, the screw hole on the chain plate member 2 is just aligned with the fastening rod 6 on the connecting seat 3. The fastening rod 6 is rotated to combine it with the screw hole, so that the connecting seat 3 and the chain plate member 2 can be fixed. When the chain plate member 2 is damaged later, the chain plate member 2 can be separated by rotating the fastening rod 6. In this way, the chain plate member 2 can be replaced independently while ensuring the convenience of independent replacement of the chain plate member 2, thereby improving the convenience of using the chain plate connection structure for the chain plate type elevator. In the initial state, the limit plate 5 is overlapped on the outer wall of the connecting seat 3 and is away from the fastening rod. 6, after the connection seat 3 and the chain plate member 2 are fixed by the fastening rod 6, the limit plate 5 is pulled to drive the connecting block 8 to completely disengage from the slot 7, and then the limit plate 5 is rotated 180 degrees, and the connecting block 8 is rotated and matched with the matching block 10 through the rotating shaft 9, and then the limit plate 5 is released, and the spring 11 pulls back the matching block 10, and the matching block 10 drives the connecting block 8 to re-engage the slot 7, and the limit plate 5 is stably abutted against the outside of the fastening rod 6. While the fastening rod 6 is isolated by the limit plate 5, the friction force generated by the contact between the limit plate 5 and the fastening rod 6 can effectively limit the loosening of the fastening rod 6, thereby improving the stability of the chain plate connection structure for the chain plate type hoist.
