DETAILED DESCRIPTION

[0031] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9As shown, a lifting work platform comprises a flat plate 1, the lower end of the flat plate 1 is rotatably connected with a bracket 2, one end of the bracket 2 is rotatably connected to the lower end of the flat plate 1 through a connecting pin, and the other end of the bracket 2 is slidably arranged on the lower end of the flat plate 1 through a pulley, one side of the lower end of the bracket 2 is fixedly connected with a first arc frame 3, and the other side of the lower end of the bracket 2 is fixedly connected with a second arc frame 4, the first arc frame 3 and the pulley are arranged on the same bracket 2, and the second arc frame 4 is fixedly connected with a wheel group, the outer end of the upper end of the bracket 2 is fixedly connected with a fixed plate 7, the end surface of the fixed plate 7 is fixedly connected with a plurality of fixed seats 8, a sleeve 9 is rotatably connected to the fixed seat 8, and a gas spring 10 is slidably connected in the sleeve 9, the output end of the gas spring 10 is rotatably connected to the lower end of the flat plate 1, and the end of the gas spring 10 is connected with a locking wire 11, and the outer side surface of the flat plate 1 is fixedly connected with a corresponding number of toggle switches 12, and the toggle switches 12 are fixedly connected to the locking wire 11, one end of the flat plate 1 is rotatably provided with an extension mechanism, and the other end of the flat plate 1 is provided with an adjustable clamping mechanism; When using the lifting work platform, first, according to the weight of the vehicle placed on the flat plate 1, the gas spring 10 is controlled to open accordingly. When the toggle switch 12 turns on the gas spring 10, the flat plate 1 is pushed upward by the corresponding gas spring 10 when it rises, which can save labor. The gas spring 10 that has not been opened is set in a sliding manner with the sleeve 9, so the gas spring 10 as a whole expands and contracts in the sleeve 9 as the flat plate 1 rises and falls. The toggle switch 12 pulls the lock line 11 outward to open the gas spring 10. This is an existing known technology and will not be introduced in detail here. When the bracket 2 rises and falls with the flat plate 1, it stretches and folds. When the bracket 2 is folded, the lower end arcs of the first arc frame 3 and the second arc frame 4 produce a rolling effect with the ground, and the second arc frame 4 can be folded more smoothly by relying on the wheel set. When the first arc frame 3 slides, it produces an effect of resisting the ground, so that it can be stable in place without moving. At the same time, the placement area of ​​the flat plate 1 can be extended by the extension mechanism at the end of the flat plate 1.

[0033] like Figure 6As shown, the extension mechanism includes an extension plate 13, a fixing rod 14 is fixedly connected to the inner side of the end of the flat plate 1, the extension plate 13 is rotatably connected to the fixing rod 14, movable grooves 15 are provided on both sides of the extension plate 13, a hanging rod 16 is movably provided in the movable groove 15, a tension spring 17 is hung between the hanging rod 16 and the fixing rod 14, a hanging groove 18 is provided at the outer end of the flat plate 1, and the hanging rod 16 is matched with the hanging groove 18; the extension plate 13 at the outer end of the flat plate 1 rotates by relying on the fixing rod 14, and when the extension plate 13 rotates upward, the hanging rod 16 slides over the lower end of the end of the flat plate 1 to move upward The outer side moves in the movable groove 15, and the hanging rod 16 is pulled by the tension spring 17. When the end surface of the extension plate 13 is horizontal with the end surface of the flat plate 1, the tension spring 17 pulls the hanging rod 16 into the hanging groove 18, and the extension plate 13 is restricted from rotating downward by the hanging groove 18. When the extension plate 13 is folded downward, the hanging rod 16 is pulled outward, and the hanging rod 16 is separated from the hanging groove 18 to fold the extension plate 13 downward. A guide wheel is rotatably connected to the outer end of the extension plate 13. When the outer end of the extension plate 13 contacts the ground, it is convenient to push the vehicle in, and a slope is provided to facilitate the vehicle to get on and off.

[0034] like Fig. 9 As shown, the adjustable clamping mechanism includes a butt plate 22, which is rotatably connected to the edge of the flat plate 1 through a hinge, a first clamping tube 23 is fixedly connected to one side of the butt plate 22, and a fixed tube 24 is fixedly connected to the other side of the butt plate 22, a rack 25 is fixedly connected to the upper ends of the first clamping tube 23 and the fixed tube 24, a moving seat 31 is slidably sleeved on the rack 25, a second clamping tube 27 is fixedly connected to the lower end of the moving seat 31, and the second clamping tube 27 is arranged to correspond to the position of the first clamping tube 23, a rocking seat 26 is rotatably connected to the upper end of the moving seat 31, a crank 30 is fixedly connected to the upper end of the rocking seat 26, a pawl 29 is rotatably connected to the rocking seat 26 through a torsion spring, a ratchet 28 is rotatably connected to the moving seat 31, the pawl 29 is matched and meshed with the ratchet 28, and the inside of the side of the moving seat 31 is connected by a torsion spring. The force spring is rotatably connected to the limit card 32; the support plate 22 is rotated through the hinge. When a battery vehicle or a motorcycle is placed on the flat plate 1, the support plate 22 is rotated upward to place the wheel between the first clamping tube 23 and the second clamping tube 27. The rocking seat 26 is rocked by shaking the crank handle 30. When the rocking seat 26 swings, the pawl 29 is driven to swing. The pawl 29 does not touch the ratchet 28 in the forward direction on the ratchet 28. When the rocking seat 26 is pressed downward, the pawl 29 presses the ratchet 28 downward, and the ratchet 28 engages with the rack 25, thereby driving the second clamping tube 27 at the lower end of the moving seat 31 to approach the wheel, and the wheel is clamped by the first clamping tube 23 and the second clamping tube 27. The rotation angle of the support plate 22 can be adjusted according to the position of the vehicle tire, so that the direction of the front wheel of the vehicle can be fixed, providing a stable clamping support effect.

When the bracket 2 is folded up and down, the rollers 6 on both sides can provide a sliding effect, thereby facilitating the folding of the bracket 2.

[0036] like Figure 2 As shown, the arc sections of the first arc frame 3 and the second arc frame 4 are arranged tangent to the ground. When the bracket 2 is folded, the first arc frame 3 and the second arc frame 4 slide more smoothly with the ground. The tangent arrangement with the ground can prevent the bracket 2 from getting stuck when folded.

[0037] like Figure 4 and Figure 5 As shown, the outer side surface of the first arc frame 3 is fixedly connected to the first connecting seat 33, and the hook 34 is rotatably connected to the first connecting seat 33 through a connecting pin. The end of the hook 34 is fixedly connected to the inside of the hook 34. The outer side surface of the corresponding position of the tablet 1 is fixedly connected to the second connecting seat 36, and the locking hook 38 is rotatably connected to the second connecting seat 36. The outer end of the second connecting seat 36 is rotatably connected to the turning handle 37, and the turning handle 37 is matched with the locking hook 38 and fixedly connected. When the tablet 1 and the bracket 2 are folded when not in use, the tablet 1 and the first arc frame 3 and the second arc frame 4 are close. At this time, when the locking hook 38 in the second connecting seat 36 on the outer side of the tablet 1 is close to the hook 34, the locking hook 38 and the hook 34 are engaged with each other. At this time, rotating the turning handle 37 180 degrees can drive the locking hook 38 to pull the hook 34 in the direction of rotation of the turning handle 37, and the locking hook 38 is matched with the locking rod 35. In this way, the tablet 1 and the bracket 2 can be locked to provide a safe inactive placement.

[0038] like Figure 1 and Figure 2 As shown, the upper end surface of the flat plate 1 is provided with expansion holes 19, and the expansion holes 19 are symmetrically distributed on the upper end of the flat plate 1 and are arranged in multiple groups, wherein expansion plates 20 are placed on two expansion holes 19, and the lower ends of the expansion plates 20 are fixedly connected with mounting pins 21, and the mounting pins 21 are matched with the expansion holes 19; multiple groups of expansion holes 19 are symmetrically provided on both sides of the flat plate 1, and two adjacent expansion holes 19 can fix one expansion plate 20, and the mounting pin 21 at the lower end of the expansion plate 20 is inserted into the expansion hole 19 and slides, and the mounting pin 21 is inserted into the smaller end of the expansion hole 19 for snap connection, so that the expansion plate 20 can be fixed.

[0039] like Figure 2 As shown, the expansion hole 19 is arranged obliquely inward; the expansion hole 19 arranged obliquely inward can make the expansion board 20 more firmly inserted, providing a more secure installation for the expansion board 20.

[0040] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention.
