A door catch includes a back plate having two laterally symmetric sleeves formed on a front face thereof. An elastic check member is mounted in a rear end of each sleeve to replace a conventional screw to confine a steel ball and a spring in the sleeve, so that the spring normally pushes the steel ball forward to partially project from a front open end of the sleeve and the elastic check member backward to firmly close the rear end of the sleeve. The steel balls projected from the two sleeves of the back plate together firmly clamp between them a stop post correspondingly mounted on a movable door leaf.

A towable, wheeled-backpack includes a towing handle attached to a curved, single-pole, telescoping towing member which retracts into the backpack when not in use. The curvature of the towing member provides support for a backing sheet that is attached to the towing member, and the backing sheet is contoured so that the backpack can be comfortably supported on a wearer's back. A rigid base with wheels is pivotally attached to a bottom end of the towing member. The pivot attachment allows the base and wheels to move independently of the towing member as the bag is worn or as the bag is rolled along the ground.

The present invention includes a housing for hanging or mounting a wire and a device in a corner between two walls of a building. The housing includes an angular back plate. The angular back plate is bifurcated at an acute angle and the backplate further includes an angular raised portion which is similarly bifurcated at an acute angle and positioned in mating relation with the angular back plate. The raised portion is recessed from top, bottom and side edges of the angular back plate. The raised portion has planar front portions in angular relation to each other and enclosing the raised portion. The back plate is mounted to a corner defined by the wall frames using back plate holes. The angular raised portion mates with a building material affixed to the building wall frame. One of the planar front portions of the angular raised portion defines a hole for passing the wire therethrough.

A panelboard is composed of modular units. Each unit has compartments for circuit breakers, side walls, and wiring gutters. A main circuit breaker unit has a main cable compartment having separate compartmentalized routing for power cables, and a compartment for the main breaker. A branch circuit breaker unit is edge connected to the main breaker unit. More branch breaker units may be added. Each branch breaker unit has a bus plane for line power, with pin-shaped stabs extending perpendicularly from its busses. The bus plane is covered by circuit breaker compartments in front and an insulative backplane in back. Branch wiring exit slots in the circuit breaker compartments lead to wiring gutters. Each unit is shaped and dimensioned to be mechanically and electrically connected together to form the whole panelboard. Caps for the wiring gutters are front accessible and constitute a front surface of the finished panelboard.

The invention relates to a vertical post with a dip angle. The vertical post comprises a connection main body and a bottom plate and is characterized in that the connection main body comprises a front plate, a back plate and a top plate, wherein the front plate and the back plate are parallel to each other and arranged in perpendicular to the bottom plate, the front plate and the back plate are of rectangular shapes, the front plate is lower than the back plate, the top plate is arranged between the front plate and the back plate and arranged with a certain dip angle, the dip angle is customized according to the optimal dip angle of each place, the bottom plate is of a rectangular shape, and the center of the bottom plate is vertically connected with the connection main body. The vertical post is convenient to use, and the vertical post and an oblique beam of a photovoltaic support can be simultaneously connected and are fixed on a foundation by a fastening element.

The invention discloses a wall-mounted hat and coat stand. The wall-mounted hat and coat stand comprises a back board fixed on a wall, horizontal beams are arranged at the upper and lower ends of thefront of the back board, edge stringers are arranged between the left and right ends of the horizontal beams at the upper and lower ends, two ends of the edge stringers press the horizontal beams, middle stringers are uniformly distributed between the two edge stringers, two ends of the middle stringers also press the horizontal beams, gaps are reserved among the middle stringers and gaps are alsoreserved between the middle stringers and the edge stringers, from top to bottom, at least two rows of hang arms are embedded in the gaps among the middle stringers and the gaps between the middle stringers and the edge stringers, a distance is formed between the upper and lower rows of hang arms, the lower parts of the hang arms are rotatably connected in the gaps among the middle stringers andthe gaps between the middle stringers and the edge stringers through rotation pins, the upper ends of the hang arms are held for overturning the hang arms, and the lower end of each hang arm pushes against the back board. The wall-mounted hat and coat stand is simple in structure and strong in decoction property, and can be used for hanging a plurality of garments and articles, and no large spaceis occupied.

The present invention relates to a multi-functional platform vehicle which comprises a vehicle body and a bracket comprising a sliding board and a back board. The sliding board is provided with a locking assembly which locks equipment to the sliding board. The back board is provided with a material pushing assembly which pushes the equipment out of the sliding board. The vehicle body is provided with a positioning assembly and is movably connected to a rolling body which allows the vehicle body to crawl on stairs. The multi-functional platform vehicle has the advantages that the equipment which is needed to be installed in a mechanism is placed on the sliding board, the vehicle body is moved to a cabinet accessory through the rolling body arranged on the vehicle body, the vehicle body is fixed to a cabinet through the positioning assembly, the equipment is pushed into the cabinet through the material pushing assembly on the back board, the workload brought by existing manual installation is effectively improved, the installation is convenient, the equipment is locked to the sliding board through the locking assembly, the sliding of the equipment in the movement process of the vehicle body is effectively avoided, the equipment is protected from being damaged, the vehicle body is allow to crawl on the stairs through the arrangement of the rolling body, and the practical performance is good.
