Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

Referring to fig. 1 and 2, the anti-crushing safety mechanism for the goods taking door of the vending machine comprises a cross rod 1, a plurality of vertical rods 2 perpendicular to the cross rod 1 and an independent position sensor 3, wherein the vertical rods 3 are slidably connected with the goods taking door a, a sliding groove for the vertical rods 2 is formed in the goods taking door a, the vertical rods 2 are respectively arranged in the middle part, the left side and the right side of the cross rod 1, the vertical rods 21 on the left side and the right side can be abutted against the position sensor 3 below when the vertical rods 22 on the left side slide downwards, the vertical rods 23 on the middle part of the cross rod of the goods taking door a are provided with compression springs 4 for driving the vertical rods 23 to move upwards, a certain gap is reserved between the cross rod 1 and the goods taking door a by the compression springs 4, when the goods taking door a moves upwards under the driving of a motor (not shown in the figure), if the cross rod 1 touches hands, the vertical rods 21 on the, the bottoms of the vertical rods 21 and 22 can reach the detection positions of the position sensor 3, the position sensor 3 can send signals to the motor to drive the motor to move the goods taking door a in the opposite direction, and the goods taking door a is prevented from extruding hands.

Preferably, among the montant 2, set up in horizontal pole a left side, quantity on right side respectively for one, it is corresponding, position sensor 3's quantity is two, no matter be horizontal pole a left side or right side extrusion people's hand, horizontal pole a can take place the slope, arouses the position sensor 3 of bottom.

In the above-mentioned scheme, position sensor 3 formula photoelectric sensor as an organic whole, transmitting part 31 and receiving part 32 are all in the same place, be equipped with recess 33 between integral type photoelectric sensor's the receiving part 32 and the transmitting part 31, the setting is equipped with the embedding piece 5 that corresponds with recess 33 size at montant (21, 22) bottom on horizontal pole a left side, right side, when embedding piece 5 embedding recess 33, the signal of transmitting part 31 can not be received to receiving part 32, then the sensor gives motor control signal, motor run in reverse.
