A device for a sweeping vehicle wiper to apply a force to the ground. The device comprises a connection plate (2) movably connected to a wiper assembly (1) of a sweeping vehicle, and the other end of the connection plate (2) is hinge-connected to a brush disk support (3). The brush disk support (3) is provided with a torsion spring (4), and the force-applying end of the torsion spring (4) applies a downward pressure to the connection plate (2). The device uses a light wiper assembly to meet the pressure requirement specified in the industry, thereby saving the manufacturing material. By means of a structure that the torsion spring applies a downward pressure, the space for mounting the tension spring may be greatly reduced, so that the structure is still applicable when the gap between the wiper assembly and the brush disk assembly is small, and therefore, the present invention has higher adaptability.
A fixing structure for a wiper of a sweeping vehicle comprises a wiper assembly (1), a gravity frame (2) disposed on the wiper assembly (1), and a wiper connection plate (3) fixed on a vehicle frame. A guide slot opened upwards is disposed in the wiper connection plate (3). A gravity shaft (4) is disposed on the gravity frame (2) on the wiper assembly (1), and the wiper assembly (1) is connected to the guide slot in the wiper connection plate (3) through the gravity shaft (4). During disassembling, the wiper assembly (1) is held and lifted upwards, so that the gravity shaft (4) departs from the guide slot and the wiper assembly (1) is lifted up steadily. During assembling, the gravity shaft (4) is mounted in the guide slot, and the wiper assembly (1), under the gravity thereof, stably fits the guide slot with the gravity shaft (4) thereof and will not fall. The wiper assembly is convenient in assembling and disassembling, and is fixed reliably.

PAD PLANE SWING CONFIGURATION FOR CLEANING THE FLOOR
Disclosed is a pad plane swing configuration for cleaning the floor,including a motor(1),pads(10,11),a fixed panel(2),and an active board(3),which is connected with the fixed panel(2). The pads(10,11) are connected fixedly below the active board(3). The motor(1) is secured on the fixed panel(2). An eccentric aperture is arranged at the output shaft of the motor(1). A bearing(14) is fixed eccentrically at the output shaft of the motor(1). The bearing(14) is arranged inside the waist-shaped slot(12) of the active board(3) and rotates inside the waist-shaped slot(12) to push the active board(3) to move back and forth, so that the pads(10,11) are driven to move. Therefore, the configuration is high in cleaning effectiveness, low in manufacturing cost and energy consumption, and does no harm to the floor.
A working method of a pad (4) in floor cleaners that the pad is swung horizontally under the control of a motor (1) is provided. The floor is cleaned by the brush of the pad (4) back and forth in two directions. The dirt is easily brushed away from the floor by using the method, so that large number of ineffective cleaning processes are decreased, and the energy consumption is low. The floor is cleaned less so that it is protected. DRWAING: FIG. 1:
A floor washer tag-along travel accessory dead-man switch and circuit thereof. The dead-man switch comprises two pedal-keys (1, 2) and a control panel, the pedal-keys (1, 2) are disposed on the foot rest (3) of the tag-along travel accessory; the pedal-keys (1, 2) are electrically connected with the control panel, the pedal-keys (1, 2) are disposed with a limiting screw (5) and a switch (6), and a compression spring (4) is disposed on the limiting screw (5). The circuit comprises a power supply circuit, a left foot rest control switch and a right foot rest control switch; the left foot rest control switch and the right foot rest control switch are connected in series to form a foot rest control switch circuit; the foot rest control switch circuit and the power supply circuit are electrically connected to the full machine controller. The floor washer tag-along travel accessory dead-man switch is simple in structure and convenient to use. The dead-man switch is installed in a standing area of the operator and will not add to operating procedures of the operator.

An adjustable direction lever includes a clutch (101,102), a locking handle (2), an upper direction lever (3), and a lower direction lever (4). The upper direction lever (3) is movably connected with the lower direction lever (4) through the clutch (101,102). The locking handle (2) is connected with the clutch (101,102) through a hinge pin (5), for controlling the opening and closing of the clutch (101,102). The adjustable direction lever can adjust operation space according to different needs. During package and transportation, the direction lever can be hidden beneath the highest point of a main body to save space. The direction bar also can be adjusted to a certain direction to facilitate maintenance.
