DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0016] like Figures 1-2 As shown, the embodiment of the utility model provides a locking mechanism for a mobile vehicle, including: a bracket 1, a locking hand wheel 2, a screw rod 3 and a tensioning hook plate 4; one end of the bracket 1 can be detachably locked on the vehicle body 6, and the other end of the bracket 1 is vertically rotatably mounted with a locking hand wheel 2, the screw rod 3 is threadedly sleeved in the axial hole of the locking hand wheel 2, the lower end of the screw rod 3 is rotatably connected with the tensioning hook plate 4, and the tensioning hook plate 4 is clamped with the guide rail 7. By rotating the locking hand wheel 2, the thread force between the locking hand wheel 2 and the screw rod 3 is utilized to make the screw rod 3 drive the tensioning hook plate 4 to move upward or downward, so as to realize the suspension clamping or separation of the tensioning hook plate 4 and the guide rail 7, thereby achieving the purpose of reliable positioning and rapid separation.

[0017] The bracket 1 includes: a locking plate 11, a reinforcing rib plate 12 and a transverse plate 13; a transverse plate 13 is transversely arranged on the right side wall of the locking plate 11, a reinforcing rib plate 12 is arranged between the transverse plate 13 and the locking plate 11, and locking holes are symmetrically opened at the front and rear ends of the locking plate 11, and the bracket 1 can be detachably locked to the vehicle body 6 through the locking screws and the locking holes. The arrangement of the reinforcing rib plate 12 can further enhance the stability of the bracket 1 when in use.

[0018] The locking hand wheel 2 comprises: a conical wheel 21 and a handle 22; the bottom axial hole of the conical wheel 21 is a threaded hole structure for threadedly sleeved with the screw 3; the top of the conical wheel 21 is detachably locked with a handle 22, and the conical wheel 21 is driven to rotate by the handle 22.

[0019] The diameter of the conical wheel 21 gradually decreases from top to bottom, which can increase the torque of the handle 22 when rotating, thereby achieving the purpose of labor saving.

[0020] The tensioning hook plate 4 includes a dovetail hook plate 41 and a connecting cavity; a connecting cavity is provided at the top of the dovetail hook plate 41, and a dovetail groove 42 is provided at the bottom of the dovetail hook plate 41. The inner side surface of the bottom of the inner cavity of the dovetail groove 42 is arranged as an inclined surface, which is used to cooperate with the inner inclined surface of the guide rail 7, thereby realizing the cooperation, clamping or separation of the inner inclined surface of the guide rail 7 through the dovetail groove 42.

[0021] It also includes a pressure plate 5, in which the screw rod 3 is movably sleeved in the axial hole of the pressure plate 5, and the lower end of the screw rod 3 also includes a rotating clamp block 31 that is integrally formed and connected, and the rotating clamp block 31 is movably clamped in the connecting cavity. The pressure plate 5 is locked to the top of the dovetail hook plate 41 by a locking screw, so that the rotating clamp block 31 can be limited in the connecting cavity and can rotate relative to the tensioning hook plate 4.

[0022] The working principle is as follows: before the trolley of the utility model moves, the locking hand wheel 2 is rotated to make the screw rod 3 move downward under the action of gravity, so that the inner side of the tensioning hook plate 4 is separated from the guide rail 7, and the trolley can be moved. When the trolley moves to the designated position, the locking hand wheel 2 is rotated to make the screw rod 3 move upward, driving the tensioning hook plate 4 to hang the inner side inclined surface of the guide rail 7, and the pre-tightening force generates a large static friction force, so that the trolley can be positioned reliably.
