The present invention provides a developing box, which includes a box body, a developing roller, a driving force receiving head, a detection mechanism, a transmission shaft and a sleeve. The box body has a carbon powder accommodating portion and a powder outlet, the developing roller is rotatably supported at the powder outlet, the driving force receiving head is arranged on the first end wall of the box body, and a tooth portion is arranged on the peripheral wall of the driving force receiving head. The detection mechanism is arranged on the second end wall of the box body. The transmission shaft is columnar and extends along the length direction of the box body. The transmission shaft is rotatably installed in the carbon powder accommodating portion. The first end of the transmission shaft is provided with a first driving wheel, the first driving wheel and the driving force receiving head are located on the same side of the box body, and the first driving wheel is connected to the driving force receiving head by transmission. The second end of the transmission shaft is provided with a second driving wheel, and the second driving wheel cooperates with a rotating member. An installation cavity isolated from the carbon powder accommodating portion is formed in the sleeve, the transmission shaft is located in the installation cavity, and the transmission shaft and the sleeve are in clearance. The developing box can reduce the torque generated by rotation.

The invention relates to the technical field of industrial size measuring equipment, in particular to a high-stability three-coordinate measuring machine which comprises an X-axis assembly arranged on a Z-axis assembly, an auxiliary support arranged at the bottom of the X-axis assembly on the opposite side of the Z-axis assembly, a probe base arranged on the X-axis assembly, and Z-axis side seats arranged on the two sides of a Z-axis base. The sliding stability of the Z-axis supporting column on the sliding bottom plate can be improved, in order to reduce friction between the Z-axis base and the sliding bottom plate and between the Z-axis side seat and the sliding bottom plate, the Z-axis base and the sliding bottom plate are arranged at intervals, an air floating seat is arranged in the interval space, and when the Z-axis supporting column needs to move on the sliding bottom plate, the Z-axis supporting column can move on the sliding bottom plate. The air floating base blows air to the sliding bottom plate, the Z-axis base and the Z-axis side base are supported to leave the sliding base, and therefore in the process that the Z-axis base and the Z-axis side base slide along the sliding base, friction losses between the Z-axis base and the sliding base and between the Z-axis side base and the sliding base are reduced.

This invention relates to a crane boom head and a crane, wherein the crane boom head includes a boom head body (10) and a first pulley assembly (20). The boom head body (10) includes a connecting part (11) for connecting to an extension arm. The first pulley assembly (20) is mounted on the boom head body (10), and a preset distance is maintained between the first pulley assembly (20) and the connecting part (11) to avoid interference between the first pulley assembly (20) and the extension arm. The crane includes the aforementioned crane boom head. This invention enables integrated transportation of the pulley structure and the crane boom head, reducing transportation costs. By maintaining a preset distance between the first pulley assembly and the connecting part, interference between the first pulley assembly and the extension arm can be avoided. When the crane needs to install an extension arm, there is no need to disassemble and assemble the pulley structure, saving the crane's disassembly and assembly time. Furthermore, the function of the pulley structure is retained for future use, thereby improving the crane's operating efficiency.

The utility model relates to the technical field of battery replacement, in particular to a tool bin and a battery replacement station. The utility model aims to solve the problem that a device for storing and replacing a battery bearing part is lacked in a battery replacement station. In order to achieve the purpose, the tool bin comprises a main body frame, the lower portion of the main body frame is provided with a containing space allowing the battery replacing robot to enter, and the upper portion of the main body frame is provided with a plurality of storage positions used for storing battery bearing parts; a lifting part arranged on the main body frame; the telescopic conveying part is arranged on the lifting part and can be driven by the lifting part to ascend and descend, the telescopic conveying part is provided with a first extending position and a first retracting position, when the telescopic conveying part is located at the first extending position, the telescopic conveying part partially enters the storage position or the containing space, and when the telescopic conveying part is located at the first retracting position, the telescopic conveying part partially enters the storage position or the containing space. And the telescopic conveying part retracts from the storage position or the accommodating space. Storage and automatic replacement of the battery bearing part can be realized, and compatibility improvement of the battery swap station is facilitated.
