[0002] An electric forklift refers to a forklift that operates with electricity, and most of them work with a storage battery. A storage battery is a type of battery, and its function is to store limited electric energy and use it in a suitable place. Its working principle is to convert chemical energy into electric energy.
[0003] At present, in order to ensure that an electric forklift can operate continuously, the battery of the electric forklift is usually swapped. When the battery swapping box is installed, it is usually connected to the electric forklift circuit in a sliding manner. In order to prevent the battery swapping box from moving accidentally, a limiting component is usually used to limit the battery swapping box. The existing limiting components can usually only limit a single battery box separately. When swapping the battery of the electric forklift, the swapping personnel need to operate multiple limiting components to release the limitation of multiple battery swapping boxes, resulting in more operation steps before battery swapping and affecting the battery swapping efficiency. Based on this, a manual locking mechanism for an electric forklift with battery swapping to solve the above problems is proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a manual locking mechanism for an electric forklift with battery swapping to solve the problems raised in the above background technique.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0020] As Figures 1 to 3 shown, the manual locking mechanism for a battery-changing forklift in this embodiment includes a connecting rod 1. An installation rod 2 is installed behind the connecting rod 1. The connecting rod 1 is a bracket for an electric forklift. The installation rod 2 is installed at the rear end of the connecting rod 1, and the connecting rod 1 and the installation rod 2 are located between two battery-changing battery installation cavities. A screw rod 3 is rotatably connected between the connecting rod 1 and the installation rod 2. A threaded block 4 is threadedly connected to the surface of the screw rod 3. A baffle 5 is installed on the surface of the screw rod 3 near one end of the connecting rod 1. By rotating the screw rod 3, the screw rod 3 drives the baffle 5 to rotate. When the baffle 5 remains vertical, it can limit the positions of two battery-changing batteries at the same time. When the baffle 5 remains horizontal, the limitation on the battery-changing batteries can be released. A first limiting plate 6 is installed at the upper end of the installation rod 2 on one side of the baffle 5, and a second limiting plate 7 is installed at the lower end of the installation rod 2 on the other side of the baffle 5. By making the two ends of the baffle 5 contact the right end of the first limiting plate 6 and the left end of the second limiting plate 7, the baffle 5 can be kept vertical. When the two ends of the baffle 5 contact the lower end of the first limiting plate 6 and the upper end of the second limiting plate 7, the baffle 5 can be kept horizontal. The front end of the screw rod 3 passes through the connecting rod 1 through a connecting shaft, and a rotating rod 8 is hinged to the front end of the connecting shaft. The setting of the rotating rod 8 facilitates driving the screw rod 3 to rotate.
[0021] Specifically, bearing members 9 are installed inside both the connecting rod 1 and the installation rod 2. Both ends of the screw rod 3 are installed inside the two bearing members 9 through connecting shafts, which can realize the rotation of the screw rod 3, and the rotation is light and labor-saving.
[0022] Furthermore, the baffle 5 is always located between the first limiting plate 6 and the second limiting plate 7. The horizontal distance between the first limiting plate 6 and the second limiting plate 7 is the same as the width of the baffle 5. The baffle 5 will not rotate in front of the first limiting plate 6 and the second limiting plate 7, effectively preventing the screw rod 3 from always driving the baffle 5 to rotate synchronously and avoiding the baffle 5 losing its limiting function.
[0023] Furthermore, a handle 10 is hinged to the end of the rotating rod 8 away from the screw rod 3. The handle 10 can rotate. The handle 10, the rotating rod 8 and the screw rod 3 can form a Z shape, which is convenient for rotating the screw rod 3 for multiple turns.
[0024] Furthermore, a placement plate 11 is installed at the front end of the connecting rod 1 on one side of the screw rod 3. The placement plate 11 is L-shaped, and the handle 10 is located inside the placement plate 11. By forming a linear shape between the rotating rod 8 and the handle 10, it is convenient to store and place the rotating rod 8 and the handle 10.
[0025] Furthermore, protective pads 12 are installed above and below one end of the baffle 5 close to the mounting rod 2. The protective pads 12 are used to protect the battery being replaced. The baffle 5 makes soft contact with the battery replacement box, and can fill the gap between the baffle 5 and the battery replacement box, avoiding abrasion on the surface of the battery replacement box.
[0026] The usage method of this embodiment is as follows: When using this manual locking mechanism for a battery replacement forklift, the connecting rod 1 and the mounting rod 2 are installed between two battery replacement boxes of an electric forklift. When it is necessary to release the limit on the battery replacement box, the rotating rod 8 and the handle 10 are taken out from the placement plate 11, and then the rotating rod 8 and the handle 10 are used to drive the screw rod 3 to rotate. The screw rod 3 drives the baffle 5 to rotate 90°, changing the baffle 5 in the vertical state to the horizontal state, so that the baffle 5 does not limit the upper and lower battery replacement boxes. Then the rotating rod 8 and the handle 10 are put back into the placement plate 11, and then the battery replacement box is processed for battery replacement. After the battery replacement is completed, the handle 10 and the rotating rod 8 are used to drive the baffle 5 to rotate in the reverse direction again, and the baffle 5 is in the vertical state. Then the screw rod 3 continues to rotate, and the screw rod 3 drives the baffle 5 to move towards the battery replacement box, so that the protective pad 12 on the baffle 5 contacts the battery replacement box, effectively avoiding the shaking of the battery replacement box. Thus, the battery replacement operation of the battery replacement box is completed, effectively avoiding the need to operate multiple limiting components.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
