The invention discloses a rotatable and selectable push type multinational power source adapter, which comprises a shell, a socket and pins with at least two of standards, wherein the socket and the pins are arranged in the shell; the shell comprises an upper cover and base; the base is rotatablely assembled on the upper cover relative to a center rotation shaft; the socket is arranged in the upper cover; the pins with different standards are arranged in the base and synchronously rotates therewith; the pins with different standards are peripherally distributed around the center rotation shaft; each pin can be arranged relative to the center rotation shaft by means of parallel sliding, so that each pin has a work position which is extended out of the shell in a sliding way and a hidden position which is retracted into the shell in a sliding way; the side wall of the upper cover is provided with a positioning slidable groove which is extended parallel with the extension direction of the pins; a sliding component which can freely slide along the positioning slidable groove is arranged correspondingly to the positioning slidable groove; and the sliding component pushes one pin to be extended at a work position which is out of the shell when the pin is rotated into a function region thereof.

The invention relates to a horizontal compressor which comprises a shell, a lower flange, an air cylinder, an upper flange and a motor. The lower flange, the air cylinder, the upper flange and the motor are sequentially arranged in the shell. An oil storage cavity is formed by the lower flange and the shell. A rotor is rotationally arranged in the air cylinder through a main shaft. The horizontal compressor further comprises a center oil hole penetrating the main shaft, a radial hole formed in the main shaft and communicating with the center oil hole, an oiling pipe fixedly connected to the end, located in the oil storage cavity, of the main shaft and communicating with the center oil hole, a lower flange back pressure groove formed in the lower flange and communicating with a sliding piece installation groove of the rotor, a groove for communicating the lower flange back pressure groove and the radial hole of the main shaft, an exhaust cavity communicating with an exhaust hole of the air cylinder and the center oil hole of the main shaft, and a fan installed at the other end of the fan, wherein the bottom end of the oiling pipe is close to the bottom of the oil storage cavity. According to the horizontal compressor, smooth stretching-out of a sliding piece during starting of the compressor and attachment between the sliding piece and the air cylinder during normal running of the compressor are effectively ensured. The invention further discloses a temperature adjusting device comprising the horizontal compressor.

The invention provides a distance measuring sensor for preventing damage to a driverless car and relates to the driverless field. The distance measuring sensor for preventing damage to the driverlesscar comprises a bearing plate; the left side surface of the bearing plate is fixedly connected with a supporting column; a big arm is arranged on the left side of the supporting column; the right endof the big arm is in sleeving connection with the left end of the supporting column and is rotatably connected with the supporting column; a small arm is arranged on the left side of the big arm; theright end of the small arm is rotatably connected with the big arm; a connecting rod is arranged between one end, running through the big arm, of the small arm and the bearing plate; the two ends of the connecting rod are rotatably connected with the small arm and the bearing plate correspondingly; the connection position of the connecting rod and the bearing plate is positioned below the supporting column; and the left end of the small arm is rotatably connected with a cross rod. According to the distance measuring sensor for preventing damage to the driverless car, an anti-collision shell, an L-shaped rod, a push rod, a sliding block and a motor are provided, so that the effect of shrinking the distance measuring sensor is achieved and the problem in the prior art that the driverless carcannot protect the distance measuring sensor easily when being scratched is solved.

An electric plug adaptor of international- universal type consists of top cover, base two sliding slots on external wall, standard plug corresponding to each sliding slot position, rotary switch including a bar sliding block and a braking button. It is featured as setting a ledge and a groove closing to ledge bottom on top of plug to let bar sliding block slide along each ledge through bar sliding slot in order to have only one plug of plug adaptor connected on independently and selectively.
