[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] The utility model provides a guide rail, such as Figures 1 to 5 As shown, it includes a guide rail main body 1, a raised end 101 is provided on one side of the guide rail main body 1, a guide rail connector 2 is movably connected to the surface of one side of the guide rail main body 1, and connecting holes 201 are provided on both sides of the surface of one side of the guide rail connector 2, and the inner arc surface of the connecting hole 201 is penetrated and connected with a fastening screw 3, one end of the fastening screw 3 is connected with a nut head, and one end of the fastening screw 3 is connected to a guide rail pressure plate 4 through the nut head, and one end of the guide rail pressure plate 4 is provided with a tightening surface 401, which abuts against the back side of the guide rail connector 2, and the middle section of the guide rail pressure plate 4 is provided with a bending portion 402, and the other end of the guide rail pressure plate 4 is provided with a hooked end 403, and a concave surface 102 is provided at the connection between the guide rail main body 1 and the raised end 101, and the outer arc surface of the hooked end 403 fits with the concave surface 102.
[0027] The connection stability of the guide rail body 1 and the guide rail connecting piece 2 is crucial. During assembly, the fastening screw 3 exerts force from both ends, and the rotating screw gradually moves closer to each other and is tightened. The guide rail pressing plate 4 acts as an intermediary, and the nut is continuously compressed, causing the pressing surface 401 of the guide rail pressing plate 4 to firmly press against the back surface of the guide rail connecting piece 2. As the nut tightening force increases, the pressing surface 401 continuously approaches. At this time, the bending part 402 in the middle of the guide rail pressing plate 4 begins to be compressed and deformed. The hook-shaped end 403 on one end is pulled by the deformation of the bending part 402, and the outer arc surface is fitted into the concave surface 102 of the guide rail body 1. Finally, a tightly connected, stable and abnormal connection state is achieved, effectively ensuring the smooth and efficient operation of subsequent equipment.
[0028] When the hook-shaped end 403 is fitted into the concave surface 102, this tight fit forms a sealed structure, making it difficult for dust particles to enter the guide rail interior through these compressed gaps, thereby effectively reducing the deposition of dust on the surface of the guide rail workpiece. Since the guide rail pressing plate 4 can prevent dust from entering the fitting part between the guide rail and the car guide shoe, it also avoids the scratching of hard particles in the dust on the surface of the guide rail. Without the protection of the guide rail pressing plate 4, dust particles will continuously wear the surface of the guide rail as the car moves up and down, making the guide rail surface rough. The dustproof function of the guide rail pressing plate 4 indirectly improves the wear resistance of the guide rail and prolongs the smoothness maintenance time of the guide rail surface.
[0029] The number of guide rail pressing plates 4 is two, and they are symmetrically distributed around the guide rail body 1. The inner arc surface of the concave surface 102 is fixedly installed with a rubber plate 5. The lower surface of the rubber plate 5 is provided with an arc-shaped part 501 on both sides. The outer arc surface of the arc-shaped part 501 abuts against the outer arc surface of the hook-shaped end 403. The side of the rubber plate 5 away from the arc-shaped part 501 is provided with a connecting surface 502 connected with the protruding end 101. One side of the connecting surface 502 is threadedly connected with a screw 503. The hole near the screw 503 of the connecting surface 502 movably connects with a hole plug 504. The number of hole plugs 504 is several and longitudinally distributed around the protruding end 101. The rubber plate 5 is fixedly installed on the guide rail body 1 through the screw 503. The inner arc surface of the hook-shaped end 403 movably connects with a mounting sleeve 6. The two side end surfaces of the mounting sleeve 6 are provided with ball joint ends 601. The two sides of the mounting sleeve 6 are provided with elastic arms 602, which are placed on both sides of the rubber plate 5. The inner arc surface of the mounting sleeve 6 is provided with a scouring pad 7, one side end surface of which is fitted to one side of the guide rail body 1. The outer arc surfaces of the two ball joint ends 601 are movably connected to the inner arc surface of the hook-shaped end 403
[0030] Meanwhile, the guide rail connecting piece 2 realizes significant improvement of wear resistance in dynamic cooperation with the convex end 101, and the rubber plate surface 5 is sleeved on the convex end 101, on the one hand, the rubber plate surface 5 can generate extrusion force after being installed in place due to its good elastic characteristics, further enhancing the close fitting degree between the concave surfaces 102 of the guide rail pressing plates 4, and eliminating the potential loose gap to the greatest extent, preventing dust and impurities from invading the key parts, and ensuring the cleanliness of the internal environment of the guide rail system.
[0031] On the other hand, when the guide rail connecting piece 2 reciprocates up and down along the convex end 101, the rubber plate surface 5 buffers and disperses the friction force that would be directly applied to the guide rail pressing plate 4, greatly reducing the wear rate of the guide rail pressing plate 4 and greatly prolonging the service life of the guide rail pressing plate 4, and it is worth mentioning that the outer arc surface of the rubber plate surface 5 is provided with a wear-resistant layer, which is made of advanced wear-resistant materials and processes, and has excellent anti-friction performance, so as to avoid the risk of falling off of the wear-resistant layer due to vibration during daily operation of the elevator, and to maintain a stable, efficient and low-wear operation state for a long time, thereby significantly reducing the maintenance frequency and cost, and the gapless cooperation between the hole plug 504 and the guide rail main body 1 can effectively prevent the invasion of foreign matters and prevent the damage of the sliding block, thereby prolonging the service life.
[0032] In order to ensure that the elastic arms 602 can stably abut each other in the hook-shaped end 403, the elastic arms 602 are squeezed by each other to generate an acting force, so as to make the guide rail pressing plate 4 and the concave surface 102 more closely connected, thereby effectively enhancing the stability of the overall structure, and at the same time, the hundred-watt cloth 7 is installed at the rear end of the installation kit 6, so that when the guide rail connecting piece 2 slides back and forth on the guide rail, the hundred-watt cloth 7 can fully play its cleaning effect and timely and effectively remove the dust attached to the guide rail.
[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
