The invention concerns a mounting arrangement for mounting an orthodontic bracket on a tooth. The mounting arrangement comprises an orthodontic bracket and a mounting aid, wherein the mounting aid can be detachably connected to the orthodontic bracket with positive engagement by pushing it onto the bracket in such a way that long sides of the side pieces of the mounting aid engage in guide grooves of the bracket.

A vehicle can have a battery unit which includes paired supporting shafts protruding in opposite directions. A battery side connector can be supported coaxially with the supporting shafts in a turnable manner. The direction in which the battery side connector is fitted and connected is the direction orthogonal to the supporting shafts. A battery holding block includes paired engaging recessed portions and a vehicle body side connector. The supporting shafts of the battery unit are inserted into the engaging recessed portions from a direction approximately orthogonal to the shaft. The battery side connector is fitted and connected to the vehicle body side connector. The battery unit is operated to turn around the supporting shaft to a position where the battery unit is fixed with the battery holding block.

A transformer assembly is disclosed which includes a housing and an electrical transformer having a tank which is positioned inside the housing. A device for electrically connecting the transformer to an electrical article outside the housing includes a shaped body having a first face which is suitable to be connected to one of the walls of the tank, and a second face which is suitable to be connected to one of the walls of the housing. The shaped body can include a deformable portion which is adapted to adjust the positioning of the second face relative to the wall of the housing to which it is suitable to be connected.

A multi-purpose water filter cartridge assembly has two sets of manifold holes formed in a top of a manifold integration board. Each set of manifold holes is composed of an inlet, a first outlet and a second outlet. The first outlet of the first set of manifold holes communicates with the inlet of the second set of manifold holes. The manifold integration board further has four sets of cartridge connection holes formed in a bottom thereof and each set is composed of a first inlet, a second inlet and an outlet. The first and second inlets of two sets of the four sets of cartridge connection holes respectively communicate with the first and second outlets of the first set of manifold holes. The inlets of the two sets of cartridge connection holes respectively communicate with the outlets of the first set of manifold holes. The first and second inlets of the other two sets of cartridge connection holes respectively communicate with the first and second outlets of the second set of manifold holes, and the inlets of the two sets of cartridge connection holes respectively communicate with the outlets of the second set of manifold holes through connection holes inside the manifold integration board. At least one filter cartridge is mounted on a bottom of the manifold integration board. The present invention can conveniently and accurately connect multiple filter cartridges in serial, in parallel or both.

The invention aims at solving the problem that an existing accumulated water discharging device is difficultly aligned to a vertical water discharging pipe accurately after being pre-buried and providing a pre-buried accumulated water discharging device. The pre-buried accumulated water discharging device comprises a fixing part and a first centering part. The fixing part is provided with a third channel. The first centering part is provided with a first through hole penetrating through the upper end face and the lower end face. The axis of the first through hole is spaced from the axis of the third channel. The first centering part can rotate in the third channel in the peripheral direction of the third channel and is further provided with a first cavity. A first water storage tank with an upward opening and a first water discharging part led to the first water storage tank are arranged in the first cavity. The lower end of the first channel of the first water discharging part extends to be below the upper edge of the first water storage tank. The first centering part is further provided with a first water outlet, and the first water outlet is formed in the lower end face of the first centering part. The first water outlet is communicated with the first cavity and the third channel. The first water outlet is located outside the first water storage tank. The pre-buried accumulated water discharging device has the advantage that the device can be conveniently and accurately connected with upper and lower vertical water discharging pipes after being pre-buried.

The invention relates to the field of cars, in particular to a gear supporting structure, a hub motor drive system and a hub motor drive axle. The gear supporting structure comprises a front end cover (24) of a drive motor assembly (2) and a gear rack (20), wherein the front end cover is provided with first supporting holes (241); the gear rack is provided with second supporting holes (201); the gear rack (20) is arranged on the front end cover; the gear rack and the front end cover jointly form an accommodating space (25); first supporting holes and the second supporting holes are in one-to-one correspondence; the corresponding first supporting holes and the second supporting holes are once processed and molded; the accommodating space is positioned between the first supporting holes and the second supporting holes. The hub motor drive system comprises the gear supporting structure. The hub motor drive axle comprises the hub motor drive system according to the claims. The coaxiality of two bearing bases for mounting a gear can be guaranteed by the gear supporting structure, the hub motor drive system and the hub motor drive axle.

This intake system structure of a power unit (5), which is mounted to a vehicle (1), and in which an internal combustion engine (2) and a power transmission 3 are integrated with each other, an air cleaner (50) is provided at a position away from a cylinder part (44) of the internal combustion engine (2), a throttle body (52) is disposed at a position close to the cylinder part, and the air cleaner and the throttle body are connected to each other by a connecting tube (51), wherein a regulating member (54) around the axis of an intake passage (52a) regulates the throttle body (52) in a position in the rotating direction around the axis with respect to the cylinder part, the throttle body is assembled to the cylinder part through an inlet manifold (53) and supported integrally, and in the throttle body, a connecting cylindrical part (60) to the connecting tube is provided with a positioning part (61) for positioning the connecting tube in the rotating direction.

The invention belongs to the technical field of data communication connection and provides a USB connection line. In the present invention, by adopting a USB connection line including a first light-emitting prompt unit and a second light-emitting prompt unit, when the first USB plug or the second USB plug of the USB connection line is connected to the USB interface of the powered electronic device, the second Both the front prompting light source and the reverse prompting light source of the first light-emitting prompt unit are powered on to emit light, and the front prompt light source and the reverse prompt light source of the second light-emitting prompt unit are both powered on to emit light, so that the user can light up according to the front and back of the empty USB plug. The mode determines its front and back, so that it is convenient to accurately connect the USB plug to the USB interface of the electronic device; if the light source on the two USB plugs of the USB cable or one of the USB plugs does not glow, it means that the line of the USB cable is damaged circuit break, thereby prompting the user to replace a normally usable USB connection cable in time.
