The invention discloses a window frame preventing dust from entering a slide groove. The window frame preventing dust from entering the slide groove comprises a window frame body and a window. The slide groove is formed in the bottom of the window frame body, and two zipper tapes are arranged at the two sides of the slide groove correspondingly and matched with each other. Two zipper heads in a reversed direction are arranged at the zipper tapes, the window is arranged between the two zipper tapes, and fixed structures used for fixing the zipper heads are arranged at the two sides of the window. Grooves holding zipper teeth of the zipper tapes are formed in the two sides of the window, guide grooves are formed in the upper and lower sides of the zipper teeth, and guide raised lines matched with the guide grooves are arranged at the two sides of the grooves downwards. By adoption of the structure in the process of moving the window, the zipper head at the front of the forward direction of the window separates the two zipper tapes and the zipper head at the back of the forward direction of the window locks the two zipper tapes, thereby making the slide groove sealed by the zipper tapes all the time, preventing the dust from entering zippers, and preventing dust and impurities from affecting the sliding of the window.

The invention belongs to the technical field of washing. The problems that cables are easily wound in the pushing / pulling process of a drawer type washing device in existing washing equipment, so thatthe pushing and pulling of cables are not smooth, and even the cables are pulled apart can be solved. The washing equipment provided by the invention comprises a shell and a washing device arranged in the shell in a sliding mode. The washing device can enter / exit the shell in a push / pull manner. The washing equipment further comprises a cable fixing device. The cable fixing device is used for fixing cables of the washing equipment and is arranged to pivot along with entering / exiting of the washing equipment from the shell. Therefore, the sliding of the washing equipment relative to the shellis not affected by the cables of the washing equipment. Cables can be prevented from being broken due to the mutual winding of the cables.

The invention discloses a crawler-type chassis telescopic mechanism, comprising a telescopic arm and a telescopic guide rail sheathed on the telescopic arm, wherein a sliding gap is arranged between the telescopic arm and the telescopic guide rail, and the telescopic arm slides along the extending direction of the telescopic guide rail in a reciprocating way. The telescopic mechanism is characterized in thatthe left and right upper sides of the telescopic arm and the top of the telescopic guide rail are inclined planes, the included angles between the left and right upper sides and the top surface are 10-60 degrees, an upper limit block is respectively arranged on the left and right upper sides of the telescopic guide rail between the telescopic arm and the telescopic guide rail, and a sliding gap is arranged between each upper limit block and the telescopic arm. In the invention, an inclined telescopic arm and the upper side of the telescopic guide rail are arranged, and a limit block is arranged at the inner side of the inclined plane of the telescopic guide rail, so that the limit block is appressed with the inclined plane of the telescopic arm under the action of gravity, limit of the telescopic arm in the left and right directions is realized, the telescopic arm is prevented form moving left and right, the phenomenon that the chassis pulls to one side is avoided, and rgw operation stability is improved.

The invention provides a power tool. The power tool comprises a shell. The shell comprises a machine shell used for containing a motor and a handle which is connected with the machine shell. An output shaft of the motor drives an output rod to move through a transmission mechanism. The output shaft is provided with an axis. The handle and the machine shell are in sliding fit connection in the extending direction of the axis. The handle is provided with a control piece. The control piece and the motor are electrically connected through a wire. The shell is provided with a winding device. The winding device tensions the wire in the winding direction of the tensioned wire. The wire can be effectively arranged, and it is avoided that sliding of the handle relative to the machine shell is affected due to the disordered wire.

The present invention relates to a rotary compensator, especially a rotary compensator with flexible rotation and high pressure resistance, comprising a first pipeline, a rotary compensator, a second pipeline, a moving base, a fixed base and a rotating sleeve. The first Both ends of a pipeline are equipped with a rotary compensator, the rotary compensator includes a rotary sleeve and a sealing seat, and the end of the rotary sleeve close to the sealing seat is placed inside the rotary sleeve, and the interior of the rotary sleeve is provided with The inner cylinder, the reinforcing rib is fixedly installed between the inner cylinder and the rotating sleeve, the end of the sealing seat away from the rotating sleeve is installed through a small head, and a sealing block is arranged between the small head and the rotating sleeve , the sealing seat is covered with a sealing gland, and a seal is installed between the sealing gland and the rotating sleeve, and the sealing gland, the sealing block, the sealing seat and the rotating sleeve are enclosed A sealed cavity is provided, and the overall device of the present invention has simple structure, good rotation flexibility, and has a certain popularization effect.

The invention discloses a floating type two-dimensional double-piston pump which comprises a pump. An oil suction opening and an oil drain opening are formed in the pump, a pump unit is arranged in the pump and comprises two cylinders, the two cylinders are fixed into the pump and are arranged in the left-right directions, and two pistons are arranged in the two cylinders and are in linkage with each other; the central axes of the cylinders coincide with the central axes of the pistons, movement components are arranged at two ends of each piston and are used for driving the piston to axially move to change the volume of a working chamber, and piston movement driving directions of the corresponding movement components at the two ends of each piston are opposite to each other; each cylinder,the corresponding piston and the corresponding movement components on two sides of the piston form a portion of the floating type two-dimensional double-piston pump, an upper portion of the floatingtype two-dimensional double-piston pump is close to a front end cover, and a lower portion of the floating type two-dimensional double-piston pump is close to a rear end cover. The floating type two-dimensional double-piston pump has the advantages that oil distribution disc structures of the traditional peripheral plunger pumps are replaced with rotary and slide double-degree-of-freedom structures of the pistons, and accordingly the floating type two-dimensional double-piston pump has continuous oil suction and drain functions; the floating type two-dimensional double-piston pump is in doublemodes, reciprocating movement is carried out by 4 times whenever each piston rotates by a circle, and oil can be sucked and drained by 16 times and are increased by 4 times as compared with single-piston pumps.
