The device comprises a motor assembly, the output end of the motor assembly is fixedly connected with a positive and negative tooth lead screw, the front side and the rear side of the surface of the positive and negative tooth lead screw are both in threaded connection with thread sleeve assemblies, the bottoms of the thread sleeve assemblies are fixedly connected with wheel rod assemblies, the bottoms of the wheel rod assemblies are slidably connected with trapezoidal blocks, and the bottoms of the trapezoidal blocks are fixedly connected with a connecting plate. The front face and the back face of the connecting plate are both in sliding connection with the inner wall of the portable box. According to the auxiliary tool box, a traditional carrying mode is changed, the vertical column assemblies are adopted to drive the universal wheels to move downwards, the auxiliary tool box does not need to be carried for a long time, and the carrying convenience cannot be affected.

This invention discloses an anti-theft alarm fastener. By integrating a position detection module, a control module, and an alarm module into the male and female buckles of an existing magnetic fastener, it achieves real-time monitoring of the fastener's connection status and automatic alarm functions upon unauthorized separation. The control module, with its function selection button, allows the fastener to flexibly switch between at least two operating modes: alarm function off or on. This greatly improves the product's practicality and applicability, meeting diverse user needs in different situations. The position detection module uses a magnetic trigger and a Hall sensor element to form a non-contact position detection module, avoiding reliability issues caused by contact oxidation, wear, or poor contact in traditional mechanical switches. Furthermore, the mating structure of the mounting groove and positioning recess improves the accuracy and consistency of detection, effectively avoiding misjudgments or missed alarms due to positional misalignment.

The utility model relates to the technical field of box-type houses, in particular to a cross beam movable chain structure of a box-type house, which comprises a stand column, a cross beam arranged on one side of the stand column, a clamping block fixedly connected to one end of the cross beam, a clamping groove arranged at the bottom end of the clamping block, and an anti-falling mechanism arranged below the cross beam. The anti-falling mechanism comprises a mounting storage groove formed in one side of the stand column, the inner side wall of the mounting storage groove is rotationally connected with an overturning block, the bottom end of the overturning block is in bolted connection with a supporting rod, and the side, close to the stand column, of the supporting rod is in bolted connection with the stand column. The cross beam is matched with the anti-falling mechanism, so that the turnover block and the clamping groove are clamped, the cross beam is supported by the turnover block and the supporting rod, when pressure borne by the cross beam is dispersed, the cross beam is prevented from being separated from the turnover block through clamping of the turnover block and the clamping groove, and therefore the cross beam is prevented from being separated from the turnover block while convenience of the structure is not affected. And the fixation of the cross beam is reinforced.

The invention discloses a climbing robot climbing arm and a using method thereof.The climbing robot climbing arm comprises a climbing robot mechanism and a convenient assembling mechanism, the convenient assembling mechanism is fixedly connected to the top of the climbing robot mechanism and comprises a connecting plate, and the top of the connecting plate is movably connected with a rotating rod through a bearing; the surface of the rotating rod is sleeved with a disc, the front side and the rear side of the top of the disc are movably connected with connecting rods through sliding pins, the sides, away from the disc, of the connecting rods are movably connected with pin shafts through rotating shafts, the outer sides of the pin shafts are fixedly connected with battens, and the bottoms of the battens are slidably connected with the connecting plates. According to the climbing arm of the climbing robot, the traditional mode that a base plate and a machine body are connected through multiple bolts is changed, the clamping plates are directly clamped in the climbing arm assembly, single pieces do not need to be connected in sequence, the overall consumed time is not long, and the assembling convenience is not affected.

A projection device, a light emission control method, and a storage medium. The projection device is characterized in that it comprises: a projection unit that emits projection light; an acquisition unit that acquires image data of an image to be projected by the projection unit from the outside; and a control unit that controls the operation of the projection unit, and the control unit makes the light intensity of the projection light become a dimmed state lower than a reference value when the acquisition unit does not acquire image data.

The invention provides a vehicle control device which ensures safety of automatic driving without compromising convenience of automatic driving. A control device (80) for a vehicle (1) is provided with an automatic driving control unit (90) that performs automatic driving for automatically performing a driving operation of the vehicle (1). The automatic driving control unit (90) is provided with: a holding request unit that requests a driver to hold a steering wheel when a predetermined driving scenario is reached; a holding state determination unit that determines whether the steering wheel holding state is a one-hand holding state or a two-hand holding state; and a gripping completion determination unit that determines, on the basis of the steering wheel gripping state, whether or not the steering wheel is in a gripping completion state in which gripping of the steering wheel is completed. The gripping completion determination unit determines whether to be a gripping completion state or to be a gripping completion state only in the case of a double-hand gripping state, in accordance with a driving scenario change in which the gripping completion state is determined at least in the single-hand gripping state or in the case of a double-hand gripping state.
