Fig. 1 is a schematic structural diagram of an ultra-thin scissor lift, which includes two ultra-thin scissor lifts 100, as shown in fig. 1, and two or more ultra-thin scissor lifts 100 are often provided for lifting a lifting object such as a car waiting for lifting in an actual lifting operation, and the detailed description is given only for the structure of one of the ultra-thin scissor lifts 100, and it should be understood that the exemplary illustration is not a limitation of the present invention.

In detail, as shown in fig. 1, the ultra-thin scissor lift 100 includes a support platform 110, a base 120, a support assembly 130 connecting the support platform 110 and the base 120, and a driving assembly 140 disposed between the support assemblies 130. The supporting component 130 is formed by a plurality of components coupled together in a scissors-like shape, for example, and the driving component 140 includes a first driving member 141 and a second driving member 142, and the lower ends of the first driving member 141 and the second driving member 142 are coupled to the base 120. The ultra-thin scissor lift 100 further comprises a locking structure 150, wherein the locking structure 150 is disposed between the first driving member 141 and the second driving member 142.

Fig. 2 is a schematic cross-sectional view of the ultra-thin scissor lift 100, and as shown in fig. 2, the locking structure 150 includes a locking mechanism 151, a stopping mechanism 152 and a force applying mechanism 153, specifically, an upper end of the locking mechanism 151 is coupled to the support assembly 130, a lower end of the stopping mechanism 152 is coupled to the base 120, and in fact, a lower end of the stopping mechanism 152, a lower end of the first driving member 141 and a lower end of the second driving member 142 are coaxially and commonly coupled to the base 120. The biasing mechanism 153 is disposed at the other end of the locking mechanism 151 (i.e., the opposite end that is pivotally coupled to one end of the support assembly 130), the locking mechanism 151 is disposed with a locking member 1510, the latching mechanism 152 is disposed with a plurality of catch members 1520, and the locking member 1510 is engageable with at least a portion of the catch members 1520 of the catch mechanism 152 at a plurality of predetermined catch positions, such as any one of a top lift position and a bottom lift position, to prevent the lift from further sliding down the catch positions and thereby increase the reliability of the lift even if the drive assembly fails.

Fig. 3 is a schematic view of a structure of one angle of the locking mechanism 151, fig. 4 is a schematic view of a structure of another angle of the locking mechanism 151, as shown in fig. 3 and fig. 4, in this embodiment, the locking mechanism 151 includes a first locking member 1511, a second locking member 1512, and a reinforcing rib 1513 connecting the first locking member 1511 and the second locking member 1512, at least one locking member 1510 is respectively provided on the first locking member 1511 and the second locking member 1512, the locking member 1510 is, for example, a tooth, and the first locking member 1511 and the second locking member 1512 are racks having at least one tooth, it can be understood that, if the concave portion between the tooth and the tooth in the rack is opened to form a through hole, the first locking member 1511 and the second locking member 1512 are through hole tracks having at least one through hole, the locking member 1510 is a through hole in the through hole tracks, and if the locking member 1510 is a through hole track, the thickness of the locking mechanism 151 can be further reduced, thereby providing the possibility of further lowering the overall depth of the lift to the ground position.

Fig. 5 is a schematic structural diagram of the stop mechanism 152, and as shown in fig. 5, the stop mechanism 152 includes a first stop 1521 and a second stop 1522 corresponding to the first locking member 1511 and the second locking member 1512, respectively, and further includes a sliding slot 1523 corresponding to the reinforcing rib 1513 and formed between the first stop 1521 and the second stop 1522, a plurality of stop members 1520 are disposed on the sides of the first stop 1521 and the second stop 1522 facing the locking mechanism 151, respectively, the first stop 1521 and the second stop 152 are, for example, racks with teeth, and the stop members 1520 are teeth on the racks, it can be understood that the teeth on the racks extend obliquely upward in the moving direction of the locking mechanism 151, and the engagement between the locking member 1510 and the stop members 1520 can be the engagement between the teeth or the engagement between through holes and the teeth. Generally, the number of the locking members 1510 is less than that of the stopping members 1520, for example, when the locking member 151 is a tooth, the number of the teeth on the first locking member 1511 and the second locking member 1512 is less than the corresponding number of the teeth on the first stopping member 1521 and the second stopping member 1522, and when the locking member 151 is a through hole, the number of the through holes on the first locking member 1511 and the second locking member 1512 is less than the corresponding number of the teeth on the first stopping member 1521 and the second stopping member 1522, so as to reduce the probability of unlocking failure and improve the stability and reliability of the unlocking function.

Referring again to fig. 2 and 4, the reinforcing ribs 1513 are configured to protrude from the locking member 1510 at least partially within the slots 1523, such that when the lift support platform 110 is retracted to the lowest ground position, the reinforcing ribs 1513 are substantially completely received within the slots 1523; as the lifter lifts, the reinforcing rib 1513 moves obliquely upward following the lock mechanism 150, and partially exits the slide groove 1523 in the extending direction of the slide groove 1523. During the lifting process of the lifting machine, the reinforcing ribs 1513 are still at least partially accommodated in the sliding grooves 1523, so that the first locking members 1511 and the second locking members 1512 can be guided to move continuously along a predetermined direction, i.e. the direction in which the first stopping members 1521 and the second stopping members 1522 extend, without deviation, and therefore the locking members 1510 of the first locking members 1511 and the second locking members 1512 are ensured to be accurately engaged with the partial stopping members 1520 of the first stopping members 1521 and the second stopping members 1522 at the predetermined stopping positions, respectively, and no lateral deviation occurs. It is envisioned that without the guidance of the ribs 1513, the locking members 1510 of the first and

second locking members

1511, 1512 may be misaligned relative to the first and

second stops

1521, 152, resulting in the locking members 1510 not being properly engaged with the stop members 1520, which may significantly reduce the safety of the lift. Similarly, when the locking member 1510 and the stopping member 1520 are disengaged during the lowering of the lift, the reinforcing ribs 1513 are still at least partially located in the sliding slots 1523 for guiding the first locking member 1511 and the second locking member 1512 to move along the predetermined direction, i.e., the direction in which the first stopping member 1521 and the second stopping member 1522 extend, without lateral deviation.

Referring again to fig. 2 and 4, the force applying mechanism 153 is secured to the other end of the locking mechanism 151 (i.e., the opposite end that is journaled to one end of the support assembly 130) by a generally L-shaped connector 154. The first side of the connecting member 154 is fixed to the locking mechanism 151, the second side of the connecting member 154 can be accommodated in the sliding slot 1523, and the force application mechanism 153 is fixedly installed on the second side of the connecting member 154 and can be partially accommodated in the sliding slot 1523. The force applying mechanism 153 is, for example, an air cylinder, a groove 15130 (as shown in fig. 3) is opened on the surface of the reinforcing rib 1513 facing the chute 1523, one section of the air pipe 1531 for supplying air to the air cylinder is accommodated in the groove, specifically, as shown in fig. 6, fig. 6 is a schematic diagram of routing of the air pipe, one end of the air pipe 1531 is connected to the air cylinder, the other end of the air pipe 1531 is connected to a gas source (not shown), the air pipe 1531 is laid along the constituent mechanism of the support assembly 130 from the gas source, extends into the groove 15130 of the reinforcing rib 1513, and finally leads to the air cylinder along the.

Referring again to fig. 1, the scissor lift 100 of the present embodiment further includes a control unit 160, and the control unit 160 can control whether the force applying mechanism 153 generates an acting force. For example, it is known that when the scissor lift 100 is in a predetermined stop position, the locking member 1510 engages with the stop member 1520, so that even if the driving assembly fails, the scissor lift 100 is prevented from further sliding down from the stop position, thereby improving the reliability of the scissor lift, and when the scissor lift 100 is lowered down from the predetermined stop position, the control unit 160 sends a control signal to control the force mechanism 153 to generate a force, so that the engagement between the locking member 1510 and the stop member 1520 is released, and the scissor lift 100 starts to be lowered. Specifically, for example, a control signal is sent to start ventilation of the cylinder, gas is initially introduced into the cylinder from a gas source, a piston rod of the cylinder applies a force to the opposing runner 1523, the runner 1523 and the piston rod interact to force the locking mechanism 151 and the stop mechanism 152 apart from each other, and the engagement of the locking member 1510 with the stop member 1520 is released, so that the lift starts to descend under its own weight.

In this embodiment, as shown in fig. 1 and 2, the ultra-thin scissor lift 100 further comprises a power assisting mechanism 170, and the power assisting mechanism 170 is used for assisting the driving assembly 140 to lift in the initial stage of the lifting of the lift 100 from the lowest position retracted to the ground. Specifically, the power assisting mechanism 170 is coupled to the supporting element 130, the upper end of the locking structure 150 and the upper end of the driving element 140 are both coupled to one end of the power assisting mechanism 170, and the locking structure 150 and the driving element 140 are coupled to the supporting element 130 via the power assisting mechanism 170.

In the present embodiment, the first driving member 141 and the second driving member 142 are oil cylinders, and it is understood that the first driving member 141 and the second driving member 142 may be other types of power mechanisms.

To more clearly understand the present invention, the following description simply illustrates the working process of the present invention.

The rising process: when the lifting button is operated, hydraulic oil is pumped out from the hydraulic oil pump and is respectively supplied to the oil cylinders, the piston rods of the driving oil cylinders and the locking mechanism move obliquely upwards together, the air cylinders do not work in the process, the locking members can be automatically engaged with the stop members by means of the gravity of the locking members, and the engagement between the locking members and the stop members is released by means of the driving of the oil cylinders in the whole lifting process, so that the lifting of the lifting machine is not influenced.

Lifting and static stage: the lifting machine stops at a preset stopping position under the driving action of the oil cylinder, the air cylinder still does not work at the moment, the locking member is still engaged with the stopping member by means of the self weight of the locking mechanism, and even if the oil cylinder has faults such as oil leakage in the process, the lifting machine can be prevented from further sliding downwards from the stopping position due to the engagement of the locking member and the stopping member, so that the reliability of the lifting machine is improved.

A descending stage: the hydraulic oil pressure returns to the tank under the action of the self weight of the lifter, and the lifter descends. For improving the security, avoid the maloperation to lead to removing of locking member and locking member, the embodiment of the utility model provides an in set up and continuously trigger the control key, the cylinder just works, in case stop triggering, the mode that the cylinder stopped working promptly.

In the whole operation process of the lifting machine, the cylinder starts to work only when a signal for ventilating the cylinder is triggered, the locking member and the stopping member are disengaged, and the locking member and the stopping member are always engaged at other times, so that the safety performance of the lifting machine is greatly improved.
