[0025] like Figure 1 —The positioning mechanism of the cargo trolley shown in FIG6 is arranged in the operating system of the cargo trolley.
[0026] The operating system of the cargo trolley includes Figure 1 2 and a trolley 15 mounted on the trolley track 14. The trolley 15 is provided with a latch 1 that can move up and down. A latch seat 2 is fixed to the ground where the trolley 15 needs to be positioned. When the trolley 15 moves to the desired position, the latch 1 and latch seat 2 cooperate to position the trolley 15. When the trolley 15 has finished loading or unloading cargo, the latch 1 moves upward and disengages from the latch seat 2, allowing the trolley 15 to continue moving on the trolley track 14.
[0027] In order to realize the positioning function of the cargo trolley, the utility model provides an embodiment of a cargo trolley positioning mechanism:
[0028] The positioning mechanism of the cargo trolley comprises a latch 1 which can move up and down and a latch seat 2 which cooperates with the latch 1 for positioning.
[0029] The latch seat 2 is fixed on a latch seat mounting bracket 16 , and the latch seat mounting bracket 16 is fixed on the ground.
[0030] The latch 1 is fixedly connected to the handle 4 via a rope 3; one end of the rope 3 is fixedly connected to the latch 1, and the other end passes over a roller 5 and is fixedly connected to the handle 4. The handle 4 is slidably disposed within a sliding sleeve 6. The sliding sleeve 6 is provided with a first limiting structure that cooperates with the handle 4 to position the handle 4 away from the latch 1 and a second limiting structure that cooperates with the handle 4 to position the handle 4 toward the latch 1. The roller 5 is mounted on a roller mounting bracket 7, and the sliding sleeve 6 is fixed to a sliding sleeve mounting bracket 13 (as shown). Figure 3 As shown, the left and right sides of the sliding sleeve 6 are fixedly connected to sliding sleeve fixing seats 17, and the sliding sleeve fixing seats 17 are provided with bolt positioning holes 18. The sliding sleeve mounting bracket 13 includes a bracket fixing rod 13.1 and a bracket fixing seat 13.2 fixed to the bracket fixing rod 13.1. The threaded rod section of the bolt passes through the bolt positioning hole 18 and is threadedly connected to the threaded hole of the bracket fixing seat 13.2, and the bolt head is positioned in the bolt positioning hole 18. The roller mounting bracket 7 and the sliding sleeve mounting bracket 13 are both fixed to the loading trolley 15. The sliding sleeve 6 is located above the roller 5 at a position corresponding to the height of a person's hand. The latch 1 is coaxially arranged in the guide cylinder 8, and the guide cylinder 8 is fixed to the loading trolley 15. A guide bushing 9 is coaxially fixed in the guide cylinder 8, which slides with the latch 1. The structure of the guide cylinder 8 ensures that the latch 1 moves up and down stably and accurately.
[0031] like Figure 5 As shown in FIG6 , the handle 4 includes a sliding rod 4.1 that slides with the sliding sleeve 6 and a handle ring 4.2 fixed to one end of the sliding rod 4.1. The sliding rod 4.1 is a cylindrical rod structure, and two limit shafts 10 are fixedly connected to the sliding rod 4.1 at intervals of 180 degrees along its circumference.
[0032] like Figure 3As shown in FIG. 4 , the sliding sleeve 6 is cylindrical in structure, with a first and second limiting structures spaced apart along the circumference of the sliding sleeve 6. The handle 4 can be rotated to selectively engage with either the first or second limiting structure. The first limiting structure includes a first limiting groove 11 defined along the length of the sliding sleeve 6 (two first limiting grooves 11 are defined along the circumference of the sliding sleeve 6 at intervals of 180°). The first limiting groove 11 is closed at the end closest to the roller 5 and open at the end farther from the roller 5. The limiting shaft 10 can be inserted through the open end of the first limiting groove 11 and retained by the closed end. The second limiting structure includes a second limiting groove 12 opened on the surface of the sliding sleeve 6 along the length direction of the sliding sleeve 6 (the sliding sleeve 6 has two second limiting grooves 12 opened at intervals of 180° along its circumferential direction). The second limiting groove 12 is closed at one end close to the roller 5 and open at the other end away from the roller 5. The limiting shaft 10 can be inserted from the open end of the second limiting groove 12 and limited by the closed end of the second limiting groove 12. The depth of the first limiting groove 11 is less than the depth of the second limiting groove 12. The second limiting groove 12 and the first limiting groove 11 are arranged at an interval of 90° along the circumferential direction of the sliding sleeve 6.
[0033] In the present invention, the positioning method of the trolley 15 by the positioning mechanism is as follows: the trolley 15 moves to the working position, the handle 4 is manually pulled, the limiting shaft 10 is disengaged from the first limiting groove 11, the handle 4 is rotated, the handle 4 is released, the limiting shaft 10 enters the second limiting groove 12, the latch 1 is lowered from the high position to the low position, and the latch 1 enters the latch seat 2 to limit the trolley 15. After the trolley 15 has finished working, the handle 4 is manually pulled again, the latch 1 is pulled up by the rope 3, the latch 1 is disengaged from the latch seat 2, the limiting of the trolley 15 is released, the limiting shaft 10 is disengaged from the second limiting groove 12, the handle 4 is rotated, the handle 4 is released, the limiting shaft 10 enters the first limiting groove 11, and the handle 4 is fixed to the high position. The operation is repeated to achieve the positioning and release of the trolley 15.
[0034] In summary, the positioning mechanism of the cargo trolley designed in the present invention has the advantages of convenient operation, flexible control, and stable structure, and can effectively realize the positioning and unlocking functions of the cargo trolley. Positioning is performed by cooperating with the latch seat 2 through the latch 1 that can move up and down, and the operation is simple and direct. When the latch 1 is inserted into the latch seat 2, the positioning of the cargo trolley 15 can be stably achieved, ensuring that the cargo trolley 15 remains stationary at the position where it needs to be fixed, thereby improving the accuracy and reliability of the parking of the cargo trolley 15. The latch 1 and the handle 4 are connected by a rope 3, and the operator can control the up and down movement of the latch 1 by pulling the handle 4, which is convenient and labor-saving to operate. The rope 3 passes around the roller 5, so that the transmission of pulling force is smoother and the resistance during operation is reduced. The handle 4 is slidably arranged in the sliding sleeve 6, and the sliding sleeve 6 is provided with a first limiting structure and a second limiting structure. The first limiting structure allows the handle 4 to be moved toward the side away from the latch 1 and then positioned. When the handle 4 is pulled to this position, the latch 1 can remain raised, facilitating the movement of the cargo trolley 15. The second limiting structure allows the handle 4 to be moved toward the side close to the latch 1 and then positioned. At this point, the latch 1 can be inserted into the latch seat 2, achieving the positioning of the cargo trolley 15. This design allows the operator to flexibly control the position of the handle 4 according to actual needs, thereby raising and lowering the latch 1, meeting the positioning and unlocking requirements of the cargo trolley 15 in different scenarios, and improving the versatility and practicality of the mechanism. The roller 5 is mounted on the roller mounting bracket 7, and the sliding sleeve 6 is fixed to the sliding sleeve mounting bracket 13. Each component is stably supported and fixed, ensuring the stability and reliability of the entire mechanism during operation. This stable structural design can withstand the various forces and vibrations generated by the cargo trolley 15 during operation and positioning, reducing the possibility of mechanism failure and extending its service life.
