The invention provides a chain guide. By employing a simple configuration, a space required for engine room can be minimized while securing enough strength, rigidity, and durability, and a reduction in a material waste, manufacturing processes, and manufacturing cost can be accomplished while occurrence of a crack or breakage during use is prevented. A chain guide (110) includes a guide shoe (110), a base member (120) configured to reinforce the guide shoe (110), and attaching sections (114). The base member (120) is formed by a bar made of a metal material.

The invention discloses a damping and impact-resistant base for a power distribution cabinet. The damping and impact-resistant base includes a damping base unit, a clamping shockproofing unit, an impact-resistant unit and a reinforcing unit, the clamping shockproofing unit is fixed above the damping base unit, the impact-resistant unit is arranged on the periphery of the clamping shockproofing unit, the reinforcing unit comprises a center column, a reinforcing rod and a third spring, the surface of the side, far away from the center column, of the reinforcing rod is provided with an installing groove, the third spring is fixed in the installing groove, one end of the reinforcing unit is connected with the impact-resistant unit through the third spring, and the other end of the reinforcing unit is connected with the damping base unit through the center column. By means of the damping base unit, support legs can better separate the power distribution cabinet from the ground to prevent the power distribution cabinet from being damaged by ground pollutant and water directly; and moreover, the damping base unit can achieve the buffer damping effects by two buffer layers vertically arranged.

The invention discloses a novel high-rise fire falling protector. The novel high-rise fire falling protector comprises a clamping device and a speed-regulating brake device, wherein the speed-regulating brake device is connected with the clamping device through a rope; the clamping device is provided with a connecting screw; an inner clamping plate is connected with an outer clamping plate by the connecting screw; a clamping effect is achieved by operating a locking handle and a secondary fastening screw; the speed-regulating brake device is provided with an eccentric wheel and a V-shaped brake rod; the eccentric position of the eccentric wheel is adjusted by a speed-regulating screw, so that falling speed is regulated and controlled; and the V-shaped brake rod is limited and fixed by a brake switch, so that escape falling stopping or starting is realized. The novel high-rise fire falling protector is used safely and reliably, mounted quickly and locked rapidly, and is reasonable in structure; the speed of the novel high-rise fire falling protector is regulated conveniently; and the novel high-rise fire falling protector is suitable for high-rise residents, and can serve as a high-rise fire self-rescuing device, and persons trapped in a fire can safely and quickly escape by using the novel high-rise fire falling protector.

The invention provides a storage box component and a refrigerator. The storage box component comprises a storage box body, a storage box cover and an anti-skid spacer, wherein the two side walls of the storage box body are provided with rotating holes; the two side walls of the storage box cover are provided with a rotating shaft; the rotating shaft and the rotating holes are matched to arrange the storage box cover on the storage box body; the anti-skid spacer is positioned between the storage box body and the storage box cover and is provided with a through hole; the through hole is matched with the rotating shaft to sleeve the anti-skid spacer on the rotating shaft of the storage box cover. According to the technical scheme, the rotating holes in the storage box body are matched with the rotating shaft on the storage box cover, so relative opening or closing of the storage box cover and the storage box body can be realized; the anti-skid spacer is also arranged between the storage box body and the storage box cover, and shake of the storage box body and the storage box cover can be prevented, so that the quality of the storage box component product is effectively improved; meanwhile, the storage box cover is prevented from falling so as not to affect the pick and place of an object by a user when the storage box cover is opened by the user.

A very large floating structure module connecting device based on flexible rods comprises two bases, two spherical hinged connecting rods, spherical hinged supports, multiple flexible rods, a plurality of connecting nuts matched with the flexible rods and a plurality of adjusting gaskets matched with the flexible rods. One ends of the two spherical hinged connecting rods are fixed to the inner surfaces of the two bases respectively, and the other ends of the two spherical hinged connecting rods are connected through the spherical hinged supports. The included angle formed between the two spherical hinged connecting rods is 180 degrees. The adjusting gaskets are placed into through holes in the bases. The two ends of the flexible rods are fixed to the two bases respectively and the flexible rods are evenly distributed on the peripheries of the bases. The device is used for connecting two independent floating structure modules, resistance tension-compressions stress and resistance bending torsion moment generated by the device composed of the bases, the spherical hinged connecting rods, the spherical hinged support, the flexible rods, the connecting nuts and the adjusting gaskets impede and limit relative motion between the two independent floating structure modules, and the device is simple in structure, easy to maintain and capable of effectively limiting relative motion between the two independent floating structure modules.

The invention discloses a connecting device for ultra-large type floating structure modules. The connecting device comprises two bases, two spherical hinge connecting rods, a spherical hinge support and a spring, one end of each of the two spherical hinge connecting rods is fixed on the inner surface of each base, the other ends of the spherical hinge connecting rods are connected through the spherical hinge support, an included angle between the two spherical hinge connecting rods is 180 degrees, the spring is spirally coiled on the two spherical hinge connecting rods from top to bottom, and the two ends of the spring are respectively fixed on the inner surfaces of the two bases. The connecting device for the ultra-large type floating structure modules stops and limits the relative motion between the two independent floating structure modules through a resisting tension-compression stress and a resisting flexion torsion moment produced by the device comprising the bases, the two spherical hinge connecting rods, the spherical hinge support and the spring. The device is simple in structure, is easy to maintain, and effectively limits the relative motion between the two independent floating structure modules.
