[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figs. 1-3 In this embodiment of the utility model, a sliding rail for lifting equipment includes a crossbeam 1, a threaded rod 2 penetrating the top of the crossbeam 1, a fixing block 3 for limiting the fixed rail 4 sleeved on the outer wall of the threaded rod 2, a fixed rail 4 being provided at the bottom of the crossbeam 1 and above the fixing block 3, and a positioning mechanism 5 provided on the crossbeam 1 and the fixed rail 4 for pre-connecting the crossbeam 1 and the fixed rail 4.
[0028] Positioning mechanism 5 includes a limiting unit and a reset unit;
[0029] The limiting unit is used to provide a limit for the pre-connection of the crossbeam 1 and the fixed rail 4;
[0030] The reset unit is used to provide a directional elastic thrust to the limiting unit;
[0031] The reset unit includes a positioning rod 502, a movable rod 503, and a spring 505;
[0032] The positioning rod 502 is fixed inside the crossbeam 1 and is used to guide the axial movement of the movable rod 503.
[0033] The movable rod 503 is slidably sleeved on the outer wall of the positioning rod 502, and the movable rod 503 is used to guide the movement of the limiting block 504;
[0034] The two ends of the spring 505 are respectively attached to the inner wall of the crossbeam 1 and the outer wall of the movable rod 503. The spring 505 is used to provide the movable rod 503 with an elastic thrust in one direction at all times.
[0035] The limiting unit includes a guide groove 501 and a limiting block 504;
[0036] The guide groove 501 is formed in the inner cavity of the fixed rail 4, and the guide groove 501 is used to limit the entry of the limit block 504;
[0037] The limiting block 504 is fixed to the bottom end of the movable rod 503. The limiting block 504 is used to cooperate with the guiding groove 501 to complete the pre-connection of the cross beam 1 and the fixed rail 4.
[0038] In this embodiment: When using this device, the bottom ends of the fixed rail 4 and the cross beam 1 are butted. During the butting process, the guiding groove 501 formed on the fixed rail 4 is butted with the limiting block 504 at the bottom end of the cross beam 1. Since the inclined surface at the bottom end of the limiting block 504 coincides with the top cross plate of the notch of the guiding groove 501, the limiting block 504 will move axially under the extrusion force. The limiting block 504 will drive the movable rod 503 to move axially along the outer wall of the positioning rod 502. The moving movable rod 503 will exert an extrusion elastic force on the spring 505 until the inclined surface of the limiting block 504 completely enters the inside of the guiding groove 501. Then, the limiting block 504 will also be clamped into the inside of the guiding groove 501 under the elastic force of the spring 505, completing the pre-connection of the cross beam 1 and the fixed rail 4, facilitating the adjustment of the distance of the fixed rail 4, and keeping the protruding length of one end of the fixed rail 4 at 500 millimeters. After that, the fixed rail 4 can be fixed by using the threaded rod 2 and the fixing block 3, reducing the operation steps of manually supporting the fixed rail 4, facilitating the rapid connection of the cross beam 1 and the fixed rail 4, and further improving the work efficiency.
[0039] Please refer specifically to Figs. 1-3 , the outer wall bottom end of the limiting block 504 is in an inclined state. The inclined surface of the limiting block 504 coincides with the outer wall of the top socket of the guiding groove 501. The cross section of the guiding groove 501 is integrally in a "convex" shape structure. The outer wall of the positioning rod 502 is integrally in a "T" shape structure. The outer wall of the positioning rod 502 matches the inner wall of the movable rod 503. A chute for the axial movement of the movable rod 503 is formed inside the cross beam 1.
[0040] In this embodiment: Through this structure, it can be clamped into the notch of the guiding groove 501 under the action of the limiting block 504. Since the cross section of the guiding groove 501 is in a "convex" shape structure, when the limiting block 504 enters the inside of the guiding groove 501, the smaller entry port of the guiding groove 501 will exert an extrusion thrust on the limiting block 504.
[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
