[0002] Mobile vehicles can be used in workshops to transport materials, such as Figure 1 A mobile vehicle is provided, which is arranged on a track. The mobile vehicle 1 is equipped with wheels 2 that can move on the track, so that the mobile vehicle 1 can move materials from one place to another on the track. At the same time, in order to ensure the safety of the mobile vehicle 1 when it is stopped, a locking device is generally required to be arranged below it, that is, a reciprocating rod 3 installed below the mobile vehicle 1, and a limiting cylinder 4 fixed to the bottom of the mobile vehicle 1. During operation, an operator is required to operate the reciprocating rod 3 below the mobile vehicle 1 so that the reciprocating rod 3 enters the limiting cylinder 4. When unlocking, the operator is also required to operate the reciprocating rod 3 below the mobile vehicle 1. This may cause certain dangers to the operator (for example, the material in the mobile vehicle 1 may accidentally fall outward and injure the operator), so the operating safety is poor.

DETAILED DESCRIPTION
[0028] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0030] In an exemplary embodiment, Figure 2-5 As shown, this embodiment provides a reciprocating structure, which includes a fixedly arranged rotating seat 5;
[0031] and a driven arm 6 rotatably mounted with the rotating seat 5, the driven arm 6 comprising a first connecting arm 7 and a second connecting arm 8 and having an included angle therebetween, the included angle being a larger acute angle or a smaller obtuse angle;
[0032] and an active arm 9, the active arm 9 is telescopically arranged and one end of which is rotatably connected to the first connecting arm 7, and the rotatable connection can be realized through a first rotating shaft 10;
[0033] and a reciprocating rod 3, the reciprocating rod 3 is rotatably connected to the second connecting arm 8, and the driven arm 6 drives the reciprocating rod 3 to reciprocate as the active arm 9 is extended and retracted;
[0034] The telescopic direction of the active arm 9 is perpendicular to the reciprocating path of the reciprocating rod 3 .
[0035] In the above embodiment, the reciprocating rod 3 is similar to that in the prior art and is arranged below the moving vehicle 1. The difference is that the active arm 9 for operating the reciprocating rod 3 can be arranged outside the bottom of the moving vehicle 1, thereby avoiding the need for the operator to go below the moving vehicle 1. This solves the problem in the prior art that the reciprocating rod 3 needs to be operated below the moving vehicle 1, which may cause accidental injury to the operator.
[0036] like Figure 2-5As shown, in a further scheme, a locking device for a mobile vehicle 1 is provided, which includes a limiting cylinder 4 arranged at the bottom of the mobile vehicle 1, and also includes the above-mentioned reciprocating structure, and the reciprocating rod 3 can enter or exit the limiting cylinder 4. Furthermore, the limiting cylinder 4 has a square opening, and the reciprocating rod 3 has a square end 23 that cooperates with the square opening, but the square opening can be wider than the square end 23, so that the reciprocating rod 3 can enter more smoothly. Specifically, the rotating seat 5 is fixed under the mobile vehicle 1, and the active arm 9 is horizontally telescopically arranged at a position outside the mobile vehicle 1, so that the operator can operate outside the range below the mobile vehicle 1. More specifically, the reciprocating structure also includes a reciprocating moving rod 11 and a fixed seat 12 for the moving rod 11 to reciprocate. The end of the active arm 9 away from the first connecting arm 7 is provided with a rotating hole 25, and one end of the moving rod 11 is rotatably arranged in the rotating hole 25. Specifically, the moving rod 11 is fixedly connected with a rotating head 24, and the rotating head 24 is rotatably arranged in the rotating hole 25. In this way, the operator can operate at a farther distance, specifically, operate the moving rod 11, which is safer; the fixed seat 12 is provided with a first limiting groove 13 and a second limiting groove 14, and the moving rod 11 is fixedly connected with an operating rod 15 at one end away from the active arm 9, and the operating rod 15 can reciprocate with the moving rod 11 into the first limiting groove 13 or the second limiting groove 14, and at this time the reciprocating rod 3 is respectively at the lowest position or The lowest position. During specific operation, the moving rod 11 is rotated by rotating the operating rod 15, and the operating rod 15 exits the first limiting groove 13. Then the moving rod 11 can be moved by the operating rod 15. The movement of the moving rod 11 causes the active arm 9 to move synchronously, thereby causing the reciprocating rod 3 to move upward through the driven arm 6 to enter the limiting cylinder 4, and then the operating rod 15 is rotated to enter the second limiting groove 14 to achieve the limiting locking of the moving vehicle 1. When the lock needs to be released, the reverse operation can be performed. More specifically, the active arm 9 and the first connecting arm 7 are relatively rotated so that the rotation of the moving rod 11 will not cause a rotational influence on the active arm 9 and the driven arm 6. When released, the reciprocating rod 3 can rely on its own gravity to return to the initial position downward. The rotating hole 25 can also be further set as a T-shaped hole, and the moving rod 11 can be set as a corresponding T-shaped head (that is, the rotating head 24 can be a corresponding T-shaped structure). In this way, the two will not be disengaged, thereby being able to pull the active arm 9 to move, causing the driven arm 6 to rotate, and then causing the reciprocating rod 3 to return to the initial position downward.
[0037] like Figure 2-5As shown, in a further solution, in order to make the reciprocating rod 3 move more smoothly, the reciprocating structure also includes a fixed guide cylinder 16, one end of the reciprocating rod 3 is slidably arranged in the guide cylinder 16, and the reciprocating rod 3 moves more smoothly under the guidance of the guide cylinder 16; further, a through groove 17 is arranged on the reciprocating rod 3 along its axial direction, one end of the second connecting arm 8 is accommodated in the through groove 17 and is connected to the reciprocating rod 3 for relative rotation through a fixed shaft 18, and the through groove 17 provides the second connecting arm 8 with the space required for rotation in the vertical direction, specifically, the fixed shaft 18 can be fixed in the middle section of the through groove 17, and the second connecting wall When rotating, it can move up and down relatively in the through slot 17, thereby avoiding interference and being unable to rotate. In more detail, the through slot 17 is located outside the guide cylinder 16, and is located outside the guide cylinder 16 (that is, located above the guide cylinder 16) during the reciprocating process, thereby avoiding the guide cylinder 16 from blocking the second connecting arm 8. In more detail, a strip hole 19 is provided on the second connecting arm 8, and the strip hole 19 surrounds the outside of the fixed shaft 18. The length of the strip hole 19 is greater than the outer diameter of the fixed shaft 18. In this way, when the second connecting arm 8 rotates, the fixed shaft 18 can also move relatively in the strip hole 19, thereby ensuring that the second connecting arm 8 rotates smoothly.
[0038] like Figure 2-5 As shown, in a more detailed scheme, the rotating seat 5 includes a first mounting arm 20 and a second mounting arm 21 and they are combined to form a U-shaped structure. The connection between the first connecting arm 7 and the second connecting arm 8 is located in the U-shaped structure and is rotatably connected to the first mounting arm 20 and the second mounting arm 21 through the second rotating shaft 22. That is, the rotating seat 5 can be fixedly installed by the first mounting arm 20 or the second mounting arm 21. That is, the rotating seat 5 can be fixed outside the bottom of the mobile vehicle 1 or directly below the mobile vehicle 1 in this scheme, and the operating rod 15 of the operating end can be set outside the bottom of the mobile vehicle 1 through the moving rod 11.
[0039] 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.
