That is, in some embodiments of the present utility model, these physical details are not necessary. Moreover, for the sake of simplicity of illustration, some well-known and conventional structures and components are shown in the drawings in a simplified schematic manner.

In order to solve the problem that the stop mechanism of the material conveying line of the automatic logistics warehouse, especially the low-temperature warehouse, has high failure rate, we design a stop mechanism with stable structure and low failure rate, the specific scheme is as follows:

referring to fig. 1-5, a stopping mechanism of a speed reducer comprises a mounting plate 1, wherein two sides of the mounting plate 1 are symmetrically and respectively fixed with a side wing plate 2 for mounting an executing mechanism, the executing mechanism comprises a rotating shaft 6 rotatably mounted in the middle of the side wing plate 2 through a bearing with a diamond-shaped seat, the rotating shaft 6 penetrates through the side wing plate 2, and two ends of the rotating shaft 6 are respectively fixedly provided with a rotating disc 7 and a chain wheel 8; the turntable 7 and the chain wheel 8 are respectively positioned on the front surface and the back surface of the side wing plate 2, in addition, the executing mechanism also comprises two sleeves 10 vertically arranged on the side wing plates 2 at the two sides of the turntable 7, a stop rod 11 is slidably arranged in each sleeve 10, and the bottom ends of the two stop rods 11 are fixedly connected through a connecting frame 12; in order to make the stop rod 11 capable of up and down reciprocating movement, achieving the effect or purpose of circulation stop, a lifting arm 14 is connected between the turntable 7 and the connection frame 12, wherein it should be noted that: the two ends of the lifting arm 14 are in rotary connection with the turntable 7 and the connecting frame 12 through the pin shaft 13, the connection point between the lifting arm 14 and the turntable 7 is positioned at the edge of the turntable 7, and the connection point between the lifting arm 14 and the connecting frame 12 is positioned at the middle part of the connecting frame 12.

When the turntable 7 rotates, according to the special design of the rotating connection and the connection position between the lifting arm 14 and the turntable 7, the lifting arm 14 can move up and down along with the turntable 7, and then by means of the rotating connection between the lifting arm 14 and the connecting frame 12, the lifting arm 14 can move up and down normally, and simultaneously, the connecting frame 12 can drive the two stop rods 11 to move up and down in the sleeve 10, so that the purpose of stopping materials is achieved.

In order to avoid the problem of freezing of the driving mechanism, the stop mechanism adopts the motor 4 as a power source, and is specifically as follows:

In order to balance the driving force obtained by the actuating mechanisms at the two sides of the mounting frame 3, the mounting frame 3 is positioned at the middle position of the back surface of the mounting plate 1, and any one of fixed connection, integral forming or welding is adopted between the mounting frame 3 and the mounting plate 1.
