[0005] Also includes an audible and visual alarm, the audible and visual alarm is connected in series with the inching switch;

[0006] The slide plate moves along the horizontal portion of the slide groove, the inching switch is turned on, and the sound and light alarm is powered on to give an alarm.

[0007] Furthermore, a partition is fixedly provided inside the horizontal portion of the slide groove, and the trigger rod passes through the partition.

[0008] Furthermore, a horizontal spring is sleeved on the outer side of the trigger rod, one end of the horizontal spring is fixed on the partition, and the other end is fixed on the slide.

[0009] Furthermore, the two right-angle rods are connected by a fixing plate, and the sound and light alarm is placed on the fixing plate. The fixing plate is close to the vertical portion of the right-angle rod and a vertical baffle is provided on the outer side of the fixing plate.

[0010] Furthermore, the two slides are connected by a fixing rod, and the horizontal limiting rod is fixed on the fixing rod.

[0011] Furthermore, the support frames are provided in plurality and the horizontal limit rods connect all the slides, and at least one sound and light alarm is provided.

[0012] Furthermore, the specific structure of the inching switch is prior art and will not be described in detail here.

[0013] Working principle: The support frame is fixed to the wall with bolts so that the horizontal limit rod is parallel to the wall. When the forklift is parked, it contacts the horizontal limit rod before hitting the wall. The horizontal limit rod drives the slide plate to move along the horizontal part of the slide groove toward the wall (when a horizontal spring is provided, the horizontal spring is compressed). At this time, due to the existence of the connecting rod, the slider compresses the vertical spring to move upward. During the movement, the slide plate drives the trigger rod to contact the moment switch. The moment switch is energized, and the sound and light alarm realizes an alarm to remind the operator; when the operator moves the forklift and the forklift is no longer in contact with the horizontal limit rod, the trigger rod is reset, the moment switch is disconnected, and the sound and light alarm is turned off.

[0014] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: it is arranged on the wall, and the contact between the forklift and the horizontal limit rod triggers the conduction of the momentary switch, so that the sound and light alarm sounds; because the momentary switch is turned on when it is pressed and disconnected when it is not pressed, when the forklift is not in contact with the horizontal limit rod, it can automatically reset, thereby turning off the sound and light alarm.
