Detailed implementation manners
[0022] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.
[0023] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the elevator guide rail connector, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.
[0024] As Figure 1-3 shown, a corrosion-resistant elevator guide rail connector includes a main body 2 for connecting the ends of two guide rails 1. Both the main body 2 and the guide rail 1 are provided with bolt holes 101 for passing through bolt assemblies. A base 3 is provided between the main body 2 and the guide rail 1. The base 3 is detachably connected with a sealing cover 4. The base 3 and the sealing cover 4 enclose a sealed space for accommodating the main body 2. The base 3 is provided with a sealing member, and the bolt assembly passes through the sealing member.
[0025] The connector is usually used for fixing when the ends of two guide rails 1 are butted. Bolt holes 101 are provided on both the guide rail 1 and the main body 2 of the connector. When the guide rails 1 are butted, after aligning the bolt holes 101 on the guide rail 1 with the bolt holes 101 on the main body 2, they are fixed by a bolt assembly. The bolt assembly includes a bolt 501 and a nut 502. After the bolt 501 passes through the bolt hole 101, it is threadedly connected with the nut 502 to complete the fastening between the guide rail 1 and the main body 2.
[0026] A base 3 is provided between the main body 2 of the above-mentioned connector and the guide rail 1. The base 3 can be made of nylon material. The nylon material has excellent mechanical properties, wear resistance, and corrosion resistance. Through the base 3, the mutual wear between the main body 2 and the guide rail 1 can be reduced, so as to maintain the reliable and stable connection of the connector to the guide rail 1 and improve the safety of elevator operation; by sealing the connector inside with the base 3 and the sealing cover 4, the corrosion rate of the connector can be slowed down, thereby prolonging the service life of the connector. While ensuring the stable operation of the elevator, the maintenance cost of the elevator can be reduced; and the base and the sealing cover 4 can also partially seal the bolt assembly inside, thereby reducing the corrosion of the bolt assembly. During the maintenance of the elevator, the bolt assembly is more convenient to disassemble and assemble, improving the convenience of elevator maintenance.
[0027] A further improvement is that, as Figure 5As shown, a recessed portion 304 matching the main body 2 is provided on the side of the base 3 adjacent to the main body 2, and the main body 2 is disposed inside the recessed portion 304. The recessed portion 304 is used to accommodate the main body 2 and at the same time play a role in limiting the main body 2. In this way, the connection stability between the base 3 and the main body 2 can be improved, ensuring a stable and reliable connection between the connecting member and the guide rail 1, and further improving the running stability of the elevator.
[0028] A further improvement is that, as Figure 5 shown, the seal includes a lining sleeve 303 integrally formed with the base 3 and a sealing washer 503 provided at the end of the lining sleeve 303. The bolt assembly passes through the lining sleeve 303. The lining sleeve 303 is provided for passing through the bolt assembly, enabling the stud assembly to fix the guide rail 1, the main body 2 and the base 3 to each other; the sealing washer 503 is used for sealing between the base 3 and the bolt assembly, thereby ensuring the sealing effect of the base 3 and the sealing cover 4 on the main body 1; the sealing washer 503 can be a rubber pad, and rubber has a certain anti-slip effect and elasticity. Through the sealing washer 503, the bolt assembly can be prevented from loosening, and further the connection stability between the guide rail 1 and the connecting member can be improved.
[0029] A further improvement is that, as Figure 3 shown, the lining sleeve 303 is coaxially arranged with the bolt hole 101 and extends into the bolt hole 101 on the main body 2 and the guide rail 1. After the lining sleeve 303 extends into the stud hole 101, the lining sleeve 303 can separate the bolt assembly from the inner wall of the threaded hole 101, reducing the gap between the two, thereby improving the connection stability of the bolt assembly to the main body 2 and the guide rail 1. At the same time, it can also reduce the mutual wear between the bolt assembly and the threaded hole 101, extend the service life of the connecting member and the bolt assembly, and reduce the operating cost of the elevator.
[0030] A further improvement is that, as Figure 2 and 3 shown, the length of the lining sleeve 303 is the same as the length of the bolt hole 101, the inner diameter of the sealing washer 503 is smaller than the inner diameter of the lining sleeve 303, and the outer diameter of the sealing washer 503 is larger than the outer diameter of the bolt hole. The lining sleeve 303 covers the entire inner wall of the bolt hole 101, which can better reduce the wear between the bolt assembly and the bolt hole 101. The sealing washer 503 can completely cover the end of the bolt hole 101 and the lining sleeve 303, and can be tightly connected to the head of the bolt 501 and the nut 502, thereby improving the sealing effect of the sealing washer 503 on the bolt hole 101 and the lining sleeve 303, and finally improving the protection effect of the sealing cover 4 and the base 3 on the main body 2 and extending the service life of the main body 2.
[0031] A further improvement is that an anti-slip layer is provided on the side of the base 3 adjacent to the guide rail 1. The anti-slip layer can be a rubber layer, which can reduce the relative sliding between the base 3 and the guide rail 1 and improve the stability of the elevator 1.
[0032] A further improvement is that, as Figure 4 and 5 shown, the sealing cover 4 is a transparent plastic bag. An elastic sealing ring 401 is circumferentially arranged at the opening of the sealing cover 4, and a circular groove 302 for accommodating the elastic sealing ring 401 is circumferentially formed around the base 3; circular self - sealing strips 301 that match each other are circumferentially arranged around the base 3 and at the opening of the sealing cover 4. The sealing cover 4 is set as a transparent plastic bag, which can reduce the operation and maintenance costs of the elevator while achieving a good protection effect. The elastic sealing ring 401 is a rubber ring, which is connected to the circular groove 302, and its position can be limited by the circular groove 302, improving the stability of their connection. Moreover, the elasticity of the elastic sealing ring 401 enables it to closely fit the inner wall of the circular groove 302, enhancing the sealing effect. And the connection method between the circular groove 302 and the elastic sealing ring 401 can improve the convenience of disassembling and assembling the sealing cover 4, thereby enhancing the convenience of elevator maintenance; the self - sealing strip 301 usually includes a pair of sealing surfaces that can be pressed or fitted together with each other. When the packaging bag is closed, these two sealing surfaces will closely fit together to form an effective sealing barrier. This sealing structure can ensure that the items in the packaging bag are not contaminated by the outside during storage and transportation. Through the setting of the self - sealing strip 301, the stability of the connection between the sealing cover 4 and the base 3 can be improved, and at the same time, the sealing effect between the two can be further enhanced.
[0033] The base 3 is made of nylon material, and the sealing cover 4 is a transparent plastic bag. The two cooperate to achieve a sealing effect on the connecting piece, slow down the corrosion rate of the connecting piece, and extend the service life of the connecting piece; during the regular maintenance of the elevator, the sealing cover 4 or the base 3 can be regularly replaced. Compared with replacing the connecting piece, the cost of replacing the sealing cover 4 is lower, so that while ensuring the safe and stable operation of the elevator, the use cost of the elevator can be reduced.
[0034] It can be understood that the present utility model is described through some embodiments.
