The present invention provides a rotary joint of a telescopic rod for connecting a bottom pipe and a support pipe, which comprises a base, a support base and a screwing member. The base comprises a first clamp for clamping the bottom pipe and a first pivot plate, and the first pivot plate comprises a guide groove. The support base comprises a second clamp for clamping the support pipe and a second pivot plate, wherein the second pivot plate comprises a through hole, the first pivot plate and the second pivot plate are pivoted together at a pivot point, and when the first pivot plate and the second pivot plate rotate relatively, the through hole is kept to align to the guide groove. The screwing member penetrates through the through hole and the guide groove to clamp and fix the first pivot plate and the second pivot plate.

The present invention discloses a two-degree-of-freedom and three-degree-of-freedom switchable ball joint structure, comprising: an outer shell with an accommodating cavity; a hollow sphere, which is located in the accommodating cavity of the outer shell and is rotatable in the accommodating cavity, wherein the lower hemispherical surface of the sphere is provided with a groove; a limiting pin, which is vertically inserted in the outer shell and located below the sphere, and the axis line of which passes through the center of the sphere; a first worm gear assembly, which is provided in the outer shell for driving the limiting pin to make a linear reciprocating motion in the vertical direction; wherein the first worm gear assembly drives the top of the limiting pin to be inserted into or exit from the groove to realize the adjustment of the degree of freedom of rotation of the sphere. The two-degree-of-freedom and three-degree-of-freedom switchable ball joint structure has the advantages of simple structure and convenient adjustment.

A display tilting apparatus (300) may include a spindle (310), a middle bearing (312) mounted on the spindle (310) and coupled to a moving bracket (304), a pair of damping thrust bearings (314) mounted on the spindle (310) and coupled to a fixed bracket (306), and a ratchet-pawl assembly (316) mounted on the spindle (310) and coupled to the moving bracket (304). The ratchet-pawl assembly (316) may cause the spindle (310) and the middle bearing (312) to rotate with the moving bracket (304) during pivoting of the moving bracket (304) to a first direction (320) such that the pair of damping thrust bearings (314) may provide a first frictional force to the moving bracket (304) in the first direction (320). Further, the middle bearing (312) may provide a second frictional force to the moving bracket (304) during pivoting of the moving bracket (304) to a second direction (322) that is opposite to the first direction (320).

The present disclosure provides an electronic device, which comprises a first frame, a second frame, a bendable hinge located between the first frame and the second frame, and a flexible member covering the first frame, the second frame, and the bendable hinge. Wherein, the electronic device further comprises a sliding member located on one side of the bendable hinge, and a supporting member connecting the sliding member and the first frame. The flexible member connects the first frame and the second frame. When the bendable hinge is bent, the supporting member can drive the sliding member to slide relative to the bendable hinge, and the flexible member can drive the second frame to slide relative to the bendable hinge.

According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.

The invention relates to an anchor device (1) with a base part (2) for attachment to an object (10), such as a load ora loading surface. The anchor device (1) also has a connecting part (6) which is held on the base part (2) and can be pivoted relative to the base part about a swivel axis (4). The base part (2) has a bearing surface (8) for contact with the object. The connecting part has an opening (12) for attaching a fastening, lifting, lashing or tensioning means. In order to increase the handling of the anchor device (1) and its operational safety, a snap mechanism (29), which has at least one snap position (30) along a pivoting movement (28) of the connecting part about the swivel axis, is provided in accordance with the invention. The snap mechanism generates a braking force (32) in the direction of the pivoting movement in front of the snap position which is reduced in the direction of the pivoting movement behind the snap position. The snap mechanism can be used to allow the connecting part to automatically assume certain positions along the pivoting movement. In addition, the snap mechanism can be used to prevent the connecting part from hitting the object or to latch the connecting part in a non-use position.

A system includes a base, and an actuator having a first end and a second end. The system also includes a shaft configured to rotate relative to the base, and a drive link fixed to the shaft. The system further includes a support arm. A first end of the support arm being fixed to the shaft such that rotation of the shaft causes commensurate rotation of the support arm. The system also includes a timing link having a first end pivotably connected to the base and a second end opposite the first end. Additionally, the system includes a mount coupled to the second end of the timing link. The mount is configured to maintain a substantially constant orientation relative to the base as the support arm transitions between a raised position and a lowered position.
