[0003] In traditional sled conveyor line systems, the sled's support legs are generally fixed and cannot be adjusted. If different workpieces share one sled, multiple supports will appear, which will appear extremely messy and increase production costs. Manual adjustments may also be required, which will result in a waste of manpower, and the adjustment accuracy cannot be guaranteed, reducing the use effect. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-3 As shown: A slide with adjustable support legs includes an overall frame 1, the overall frame 1 includes two frame side beams 101 that are parallel and spaced apart, a support frame is fixedly installed at the middle position of the two frame side beams 101, and a plurality of adjustable support legs 103 are provided on the support frame. The overall structure of the adjustable support leg 103 includes a sliding support leg 1031, a limiting block 1032 is fixedly installed on the upper end of the sliding support leg 1031, and the lower end of the sliding support leg 1031 is slidably installed on the support frame through a sliding assembly, and a positioning locking device 104 for locking the position of the sliding support leg 1031 is provided on one side of the sliding assembly.

[0025] The support frame includes a support beam 106, which is fixedly installed at the upper middle position of the two frame side beams 101. The support beam 106 and the frame side beam 101 are arranged vertically, and both ends of the support beam 106 extend to the outside of the two frame side beams 101 away from each other on one side.

[0026] A group of connecting beams are fixedly installed on both sides of the supporting beam 106 between the two frame side beams 101. Each group of connecting beams includes two parallel and spaced connecting beams 107. The connecting beams 107 and the frame side beams 101 are arranged perpendicularly, and the two ends of the connecting beams 107 are fixedly connected to the frame side beams 101 respectively.

[0027] A mounting beam 108 is fixedly installed between two adjacent connecting beams 107 . The mounting beam 108 and the connecting beams 107 are arranged perpendicularly, and both ends of the mounting beam 108 are fixedly connected to the corresponding connecting beams 107 .

[0028] In this embodiment, the support beam 106 and the frame side beam 101 , the connection beam 107 and the frame side beam 101 , and the installation beam 108 and the corresponding connection beam 107 are fixedly connected by welding or bolts.

[0029] In this embodiment, there are four adjustable support legs 103, and the four adjustable support legs 103 are respectively a first adjustable support leg, a second adjustable support leg, a third adjustable support leg and a fourth adjustable support leg. The first adjustable support leg and the second adjustable support leg are respectively fixedly mounted on the support beam 106 near its two ends; the third adjustable support leg and the fourth adjustable support leg are respectively fixedly mounted on two mounting beams 108.

[0030] A plurality of supporting blocks 102 are fixedly mounted on the supporting cross beam 106 and the connecting beam 107 , and the upper end surfaces of the supporting blocks 102 are flat.

[0031] The frame side beam 101 is provided with lifting rings 105 near both ends thereof, and the lifting rings 105 are integrally connected to the frame side beam 101 .

[0032] The sliding assembly includes a sliding block 1033 fixedly mounted on the lower end of the sliding support leg 1031. The sliding block 1033 is slidably mounted on a sliding rail 1034. The sliding rail 1034 is arranged along the sliding direction of the sliding support leg 1031. A mounting plate 1035 is fixedly mounted on the lower end of the sliding rail 1034.

[0033] With this design, the cooperation between the sliding block 1033 and the sliding rail 1034 can support the sliding support leg 1031 to slide, thereby adjusting the position of the sliding support leg 1031 and facilitating use.

[0034] In this embodiment, the mounting plate 1035 of the adjustable support leg 103 is fixedly mounted on the corresponding support beam 106 and the mounting beam 108, respectively, and the adjustable support leg 103 can be slidably mounted on the corresponding support beam 106 and the mounting beam 108 through the cooperation of the sliding block 1033 and the sliding rail 1034, which facilitates assembly and installation.

[0035] The positioning and locking device 104 includes a positioning block 1041 , which is fixedly mounted on one side of the mounting plate 1035 . The positioning block 1041 and the slide rail 1034 are arranged in parallel.

[0036] A plurality of positioning grooves 1042 are formed on the outer surface of the positioning block 1041 , and the plurality of positioning grooves 1042 are arranged at intervals.

[0037] In this embodiment, the opening position of the positioning slot 1042 corresponds to the parking position of the sliding support leg 1031 .

[0038] A mounting bracket 1043 is fixedly mounted on one side of the sliding support leg 1031 , a hinge shaft 1045 is fixedly mounted in the middle of the mounting bracket 1043 , and a swing arm 1044 is rotatably connected to the hinge shaft 1045 .

[0039] The swing arm 1044 is hinged to the mounting frame 1043 via a hinge shaft 1045 , which facilitates assembly and installation.

[0040] The hinge shaft 1045 is sleeved with a torsion spring 1046 , and both ends of the torsion spring 1046 are respectively connected to the mounting bracket 1043 and the swing arm 1044 .

[0041] The upper end of the swing arm 1044 is provided with a pressing surface, and the lower end of the swing arm 1044 is located on one side of the positioning block 1041 and is integrally connected with a positioning block 1047 , which is engaged with the positioning slot 1042 .

[0042] With this design, in the initial state, the torsion spring 1046 outputs elastic force to push the swing arm 1044 to rotate along the hinge shaft 1045. At this time, the positioning block 1047 at the lower end of the swing arm 1044 is engaged in the corresponding positioning groove 1042. The position of the sliding support leg 1031 can be limited by the engagement of the positioning block 1047 with the positioning groove 1042, which is convenient for use.

[0043] When the pressing surface at the upper end of the swing arm 1044 is pressed, and the pressing force is greater than the elastic force of the torsion spring 1046, the pressing force on the swing arm 1044 overcomes the elastic force of the torsion spring 1046 to cause the swing arm 1044 to rotate along the hinge shaft 1045. At this time, the swing arm 1044 drives the positioning block 1047 to swing to the side away from the positioning slot 1042, thereby causing the positioning block 1047 to disengage from the positioning slot 1042 for easy use.

[0044] At this time, by applying a moving force to the sliding support leg 1031, the sliding support leg 1031 can be driven to move on the slide rail 1034 to adjust the position of the sliding support leg 1031. After the adjustment is completed, the pressing pressure on the upper end of the swing arm 1044 is released. At this time, the torsion spring 1046 outputs elastic force to push the swing arm 1044 to swing, so that the positioning block 1047 is engaged with the corresponding positioning slot 1042, and the position of the sliding support leg 1031 can be limited again.

[0045] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of this utility model.
