The utility model discloses a limiting mechanism of an automobile lower back door, which comprises a sleeve which is provided with an opening end and is fixed with the lower back door, an inhaul cable which is provided with one end extending out of the opening end of the sleeve and is arranged in the sleeve in a telescopic mode, and a guide piece which is arranged at the opening end of the sleeve. The small end of the through cavity structure is communicated with the open end of the sleeve, and the inhaul cable penetrates through the through cavity structure and is in sliding contact with the inner wall of the through cavity structure and the end of the large end. The through cavity structure does not affect passing of the inhaul cable, the side wall of the outlet end of the sleeve is expanded outwards through the through cavity structure, the bending radius of the inhaul cable is increased, when the lower back door is completely opened, the inhaul cable is just matched with the long side position of the large end of the through cavity structure at the moment, the minimum bending radius of the inhaul cable at the bearing position is increased, and the service life of the inhaul cable is prolonged; and the operation durability of the whole limiting mechanism is improved.

The invention discloses a reinforcing steel bar inclined interactive locking bridge deck slab connecting structure and a design method. A first prefabricated bridge deck slab and a second prefabricated bridge deck slab reserve first inclined gate-type reinforcing steel bars and second inclined gate-type reinforcing steel bars at the transverse end of a wet joint correspondingly and are arranged at equal intervals in the length direction of the wet joint; the first inclined door-type steel bar and the second inclined door-type steel bar are mutually sleeved and locked to form an inclined interaction locking shape, the horizontal lap joint length of the inclined interaction locking inclined door-type steel bars and the minimum width of the wet joint are determined, and at least four longitudinal straight line penetrating steel bars vertically penetrate through the whole wet joint length from the corners of the inner periphery of a hole channel formed by inclined interaction locking. By means of the first inclined door-type steel bars and the second inclined door-type steel bars which are arranged in the inclined mode, the length of the middle-section rotary steel bars is increased, the problem that thin plate structure connecting steel bars cannot be bent in a rotary mode is solved, the tensile bearing capacity of connection is greatly improved compared with linear steel bars, and meanwhile the lap joint length of the reserved steel bars can be reduced.

The application discloses a kind of hollow and solid core fiber hybrid fiber bundle and cable comprising it, belong to optical fiber communication technical field, including hollow optical fiber, solid core optical fiber (solid core optical fiber can be G.652D, G.654E or G.655 etc.), first layer resin and second layer resin;It is arranged at the center position of fiber bundle by hollow optical fiber, to ensure that the bending radius of hollow optical fiber is maximum when fiber bundle bends, reduce the bending loss of hollow optical fiber, while a layer of low modulus resin is coated on the outer periphery of hollow optical fiber to reduce the bending stress of hollow optical fiber;At the same time, high modulus resin is filled in the outer periphery of low modulus resin to ensure the mechanical properties of fiber bundle, and the multiple solid core optical fibers mixed in the fiber bundle are arranged as annular distribution on the outer side of hollow optical fiber by setting, to protect the middle hollow optical fiber by solid core optical fiber, further improve the mechanical strength of the whole fiber bundle.

This utility model relates to the field of elevator auxiliary accessories technology, and in particular to a compensating chain for elevators with an ultra-large bending radius. The utility model includes: an iron chain; an inner layer of PVC covering the outer surface of the iron chain; a steel wire mesh surrounding the inner PVC layer; and an outer layer of PVC covering the steel wire mesh. The thickness of the inner PVC layer is 2-4 mm. The steel wire mesh is made of 0.3-1.0 mm ultra-tough steel wire. The mesh spacing of the steel wire mesh is 0.5-10 mm. The thickness of the outer PVC layer is 2-5 mm. The technical solution of this utility model solves the problem in the prior art where the PVC outer layer of the compensating chain breaks due to wear, corrosion, and aging after long-term use, leading to elevator operational safety issues.

The utility model discloses a dental multifunctional motor handle, including motor, motor has: motor casing, the rear end cover center position is protruding a circular accommodating cavity to rear, motor shaft, the tail of motor shaft is equipped with round magnet, and the round magnet is radial magnetization, circuit board, is located the rear of accommodating cavity, and is separated with the cavity wall of accommodating cavity between the round magnet, protection shell and apron, the rear end face of rear end cover, the inside surface of protection shell with apron constitute the protection cavity of accommodating circuit board. The utility model control is more accurate and stable, and can realize lower speed and realize greater torsional force, can satisfy dental implant and dental root canal treatment demand, guarantee the sealing of the bearing room of motor shaft and round magnet, prevent water vapor from infiltrating, avoid cooling gas and motor internal contact.
