[0013] Figure 2 This is a partial structural schematic diagram of the present invention. Detailed Implementation
[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0016] Example 1
[0017] See Figure 1 and Figure 2 As shown, the elevator guide rail involved in this embodiment includes a guide rail body 100 that extends vertically and has a "U"-shaped cross-section. Mounting plates 1 are respectively provided on the left and right sides of the guide rail body 100. The guide rail body 100 includes two side guide plates 2 arranged symmetrically on the left and right, and a front guide plate 3 connecting the two side guide plates. A row of screw holes 4 arranged at intervals along the length direction is opened on the front guide plate 3. Screws 5 are inserted into the screw holes 4. Graphite column adjusting blocks 6 are threadedly connected to the screws 5 and are disposed between the two side guide plates. The graphite column adjusting blocks 6 extend along the length direction of the guide rail body 100. The surface of the graphite column adjusting block 6 facing the side guide plate has an active guide slope 601. The surface of the side guide plate 2 facing the graphite column adjusting block has a driven guide slope 201. Graphite column filling holes 7 are opened on the side guide plate 2. A lubricating graphite column 8 with one end protruding from the opening and abutting against the graphite column adjusting block is embedded in the graphite column filling hole 7.
[0018] Furthermore, the screw 5 is fitted with an elastic element 9, one end of which abuts against the front guide plate and the other end against the graphite column adjustment block. The elastic element 9 is a compression spring.
[0019] Furthermore, the mounting plate 1 has mounting holes 11.
[0020] In this embodiment, the lubricating graphite column 8, which protrudes slightly from the graphite column filling hole 7, is worn down by the guide shoe that slides relative to it, forming graphite powder that fills the space between the guide rail and the guide shoe for continuous lubrication. After a relatively long period of relative sliding, the graphite powder is somewhat worn away. By further tightening the screw 5, the graphite column adjusting block 6 is moved closer to the front guide plate 3, until the active guide slope 601 moves towards the driven guide slope 201, thereby squeezing the lubricating graphite column 8 to increase the size of the lubricating graphite column 8 in the elongated graphite column filling hole 7, thus achieving a longer continuous lubrication effect.
[0021] The mounting hole 11 is used to fix and install the elevator guide rail.
[0022] Example 2
[0023] See Figure 1 and Figure 2 As shown, the elevator guide rail involved in this embodiment is further configured, based on embodiment 1, with the front guide plate 3 having a recess 10 for the screw rotating head to be embedded in.
[0024] In this embodiment, the recess 10 is used as a screw head for embedding the screw 5, so that the screw head does not protrude from the front end face of the front guide plate 3, thus avoiding interference with the guide shoe that slides relative to the guide rail.
[0025] The elevator guide rail involved in this utility model uses lubricating graphite columns as the self-lubricating function of the guide rail surface, which provides continuous lubrication and a long lubrication time; and by adjusting the length of the lubricating graphite columns extending out of the orifice, the lubrication time can be extended, resulting in a long service life, complete overall functions, and strong practicality.
