Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1, fig. 3 and fig. 4, the utility model discloses a but mobile station car of auto-lock, including platform truck body 1, be located front caster 2 of platform truck body 1 the place ahead bottom and be located two rear caster 3 of platform truck body 1 rear bottom, two rear caster 3 are the collinear fixed wheel of shaft, front caster 2 is for following vertical axis pivoted universal wheel, front caster 2 is last to have a cotter 21 that has slot 211, platform truck body 1 has lever structure's bolt 11 in the top pin joint that lies in front caster 2, the trailing arm of bolt 11 has a portion 111 that bends down that can insert slot 211, the upper portion at platform truck body 1 rear is equipped with pushing hands 12, the place ahead of pushing hands 12 is equipped with and is used for operating the wobbling self-lock device 4 of bolt 11. The mobile trolley pushes the pushing handle 12 to advance by a person, and the self-locking device 4 is controlled without the need of separating hands from the pushing handle 12. When the mobile trolley needs to turn, the self-locking device 4 drives the rear arm of the bolt 11 to tilt upwards, so that the downward bending part 111 is separated from the slot 211; when the mobile trolley is not steered, the self-locking device 4 drives the rear arm of the bolt 11 to descend, so that the downward bending part 111 is clamped into the bolt 211. The mobile trolley can switch states between linear movement and steering, and is simple to operate. In practical application, the self-locking device 4 may be a mechanical driving structure, or any mechanism capable of controlling the swinging of the bolt 11, such as an electric remote control structure, a pneumatic driving structure, and the like.
As shown in fig. 3 and 4, front casters 2 are disposed on both sides of the front of the trolley body 1, and each front caster 2 is provided with a latch 11 for self-locking. The mobile trolley can adopt a four-wheel moving structure, and two bolts 11 are used for respectively controlling two front caster wheels 2.
As shown in fig. 1 and 2, the self-locking device 4 is an operating handle 41 capable of moving far and near relative to the pushing handle 12, and the operating handle 41 is connected to the front arm end of each latch 11 through a rope 42. The self-locking device 4 which is similar to the bicycle brake principle is adopted, and accessories are convenient to match.
As shown in fig. 1 to 4, the rear portion of the carriage body 1 has a pair of rear threading plates 13 for threading the front section of the rope 42, the lower portion of the carriage body 1 has a pair of middle threading plates 14 for threading the middle section of the rope 42, the carriage body 1 is provided with a lower threading plate 15 above the front caster 2, and the rear section of the rope 42 passes through the lower threading plate 15 and is connected to the front arm end of the latch 11. The rope 42 can be laid close to the frame structure of the trolley body 1 by the threading plate, and the influence on the walking of the mobile trolley caused by hanging foreign matters is avoided. In practical application, the threading plate does not need to be of an exposed structure, and can also be of a hidden structure positioned in the frame of the trolley body 1.
As shown in fig. 4, the top end of the downward bending part 111 is in a structure that two sides are retracted. Because the downward bent portion 111 is inserted into the slot 211, the downward bent portion 111 is retracted properly to facilitate the insertion of the latch 11 with automatically aligned position in order to avoid the unsmooth positioning.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
