Background

With the development of electronic technology and internet technology, the production of certificates can be performed on self-service equipment, which comprises a certificate making module, a certificate printing module and a display module, so that the weight of the whole equipment is increased, and the equipment is inconvenient to carry or move.

The bottom of the existing printing terminal cabinet is moved by mounting universal wheels, when the cabinet is kept stand, the weight of the cabinet is completely borne by four universal wheels, and the universal wheels can be damaged due to large weighing.

The diameter ratio of the gear H76 to the gear G74 is larger than 1, so that the length of the lifting rod B77 at the rear side of the cabinet body 1 is larger than that of the lifting rod A at the front side of the cabinet body 1, and therefore, the moments born by the front person and the rear person when the front person and the rear person lift the cabinet body 1 which is light in front and heavy in back are balanced.

The structure in the cabinet body 1 of the invention does not interfere with the automatic door 15, the certificate making module 16 and the certificate printing module 18.

The working process of the invention is as follows: in the initial state, the cabinet 1 is still on the ground, and the four support rods 59 are pressed against the ground. The slide bar 23 extends to the limit state in the guide sleeve A20, the spring A22 is in the stretching state, the limiting rod A30 is inserted into the limiting groove A24 on the corresponding slide bar 23, the spring B32 is in the stretching state, and the trigger plate 34 is positioned in front of the universal wheel 19 and keeps a certain distance with the ground. The pull rod 83 is located in the U-shaped groove 5, the volute spring 40 is in a compressed state, the limiting rod B43 is not inserted into the limiting groove B42 on the corresponding guide rod 41 and abuts against the side face of the corresponding guide rod 41, and the spring C46 is in a compressed state. The limiting rod C52 is inserted into the corresponding limiting groove C56 on the pushing handle 55, the spring D53 is in a compressed state, and the pull rope 50 is in a stretched state. The lifting rod A73 is completely contracted in the corresponding sliding groove F14, the lifting rod B77 is completely contracted in the corresponding sliding groove D11, the sharp-angled end of the limiting rod D80 is inserted into the tooth groove 78 on the lifting rod B77, and the spring E81 is in a compressed state.

When the cabinet needs to be lifted to a higher position where the cabinet cannot be reached by translation, firstly, the lifting rod B77 slides out of the corresponding sliding groove D11 for a certain length by pulling the pull ring 79 at the tail end of any one lifting rod B77, the lifting rod B77 drives another gear H76 and two gears G74 to synchronously rotate through the corresponding gear H76 and the rotating shaft E75, the two lifting rods B77 synchronously slide out of the corresponding sliding grooves D11, and the two lifting rods a73 synchronously slide out of the corresponding sliding grooves F14 for a certain length.

When the lifting rod B77 slides out of the sliding groove D11, the corresponding limiting rod D80 jumps back and forth under the action of the tooth groove 78 on the lifting rod B77 and the corresponding spring E81 without hindering the movement of the lifting rod B77 sliding out of the sliding groove D11, when the lifting rod B77 slides out for a certain length, the tip end of the limiting rod D80 is inserted into the tooth groove 78 under the action of the spring E81 to limit the contraction of the lifting rod B77 into the sliding groove D11, the lifting rod A73 and the lifting rod B77 are guaranteed not to contract into the cabinet body 1 due to the shaking of the cabinet in the lifting process of the cabinet, and the cabinet is further guaranteed to be effectively lifted through the lifting rod A73 and the lifting rod B77.

When the cabinet is lifted to a target position at a higher place, the pull rings 79 at the ends of the two spacing rods D80 are pulled, the pull rings 79 drive the tips of the corresponding spacing rods D80 to be separated from the tooth grooves 78 on the side walls of the corresponding lifting rods B77, the contraction limitation of the lifting rods B77 to the sliding grooves D11 is released, and the springs E81 are further compressed. The lifting rod B77 is pushed into the sliding groove D11, and the lifting rod B77 drives the other lifting rod B77 and the two lifting rods A73 to complete contraction through a series of transmission. Then, the pulling force on the stopper rod D80 is removed, and the stopper rod D80 is reinserted into the tooth groove 78 on the lifting rod B77 under the restoring action of the corresponding spring E81 and fixes the position of the lifting rod B77 in the sliding groove D11, so that the operation of lifting the cabinet to a higher position is finished.

When the cabinet needs to be horizontally moved to another place on the ground where the cabinet is located, the rotating shaft D71 is rotated by a hexagonal wrench, the rotating shaft D71 drives the rotating shaft C68 to rotate through the gear F70 and the gear E69, the rotating shaft C68 drives the two gears D67 to synchronously rotate, the two gears D67 respectively drive the corresponding gear B64 on the rear side of the cabinet to rotate, the gear B64 on the rear side of the cabinet drives the gear B64 on the front side of the cabinet to rotate through the corresponding gear C65 and the rotating shaft B66, and therefore synchronous rotation of the four gears B64 is achieved.

Each gear B64 drives the corresponding internal thread sleeve 62 to rotate relative to the corresponding seat sleeve 61 through the corresponding ring sleeve B63, and the internal thread sleeve 62 drives the corresponding support rod 59 to retract towards the inside of the cabinet body 1 away from the ground through the corresponding screw 60, so that the four support rods 59 synchronously retract towards the inside of the cabinet body 1. When the four support rods 59 are completely retracted into the corresponding slide grooves a7, the four support rods 59 release the auxiliary support of the universal wheel 19 without interfering with the ground projection, and then, the rotation of the rotating shaft D71 is stopped.

Then, the pull rod 83 is pulled out of the U-groove 5 at the front side of the cabinet 1, and the two scroll springs 40 are further compressed while the pull rod 83 swings out of the U-groove 5 around the corresponding round pin 37. Then, one person pulls the pull rod 83, the other person pushes the push handle 55 at the rear side of the cabinet 1, the two persons push and pull the device horizontally to the destination, when two trigger plates 34 or one trigger plate 34 in front meet with the protrusion of the ground, the trigger plate 34 drives the corresponding trigger rod 33 to slide obliquely upward in the sliding groove G25 of the slide bar 23 under the action of the protrusion of the ground, the vertical part of the trigger rod 33 slides upward in the sliding groove I31 on the corresponding limit rod a30 and simultaneously drives the limit rod a30 to slide horizontally in the corresponding guide sleeve C29, the limit rod a30 quickly separates from the limit groove a24 on the slide bar 23 and releases the contraction limit of the slide bar 23 into the corresponding guide sleeve a20, the spring B32 is further stretched, and the slide bar 23 contracts to the limit in the guide sleeve a20 instantly under the pulling of the corresponding spring a 22. The momentary retraction of the slide bar 23 into the guide sleeve a20 causes the pull rod 83 to momentarily collapse under the pull of a person in front of the pulling force, thereby alerting the person pulling the pull rod 83 in front of the pulling force that there is a bump in the ground and that the castor 19 is about to hit the bump in the ground.

Meanwhile, the two limit rods A30 respectively pull the corresponding limit rods C52 through the pull ropes 50 to move, the limit rods C52 are separated from the limit grooves C56 on the push handle 55 instantly and limit the push handle 55 is removed, the spring D53 on the limit rods C52 is further compressed, the push handle 55 is pushed by one person at the back to instantly slide in the cabinet body 1 to a smaller extent, the push handle 55 is enabled to lose the limit of the two limit rods C52 and instantly disappear to flash under the push of one person at the back, and therefore the ground of one person at the back is reminded to have a bulge and meet with the front universal wheel 19.

Two persons who obtain the warning stop the push-and-pull to the cabinet body 1 immediately this moment for cabinet body 1 stop motion, thereby guarantee that cabinet body 1 can not take place to topple over because of the place ahead universal wheel 19 bumps with ground.

Then, the pull rod 83 is continuously swung downwards by a certain extent around the round pin 37, the pull rod 83 drives the two guide rods 41 to slide by a certain extent around the round pin 37 in the corresponding guide sleeve B26, the volute spring 40 is further compressed, the limit groove B42 on the guide rod 41 is just opposite to the corresponding limit rod B43, and the escape inclined plane end of the limit rod B43 is instantly inserted into the limit groove B42 under the action of the corresponding spring C46 and limits the upward swing of the pull rod 83 around the round pin 37.

Then, the pull rod 83 is lifted upwards, the pull rod 83 lifts the front side of the cabinet body 1 by a certain range, so that the two front universal wheels 19 are lifted and raised above the ground, the pull rod 83 is pulled forwards, the pull rod 83 drives the cabinet body 1 to move forwards continuously, so that the two front universal wheels 19 cross the ground, the front side of the cabinet body 1 is put down, the two front universal wheels 19 of the cabinet body 1 cross the ground and abut against the ground, the pull rod 83 is pulled forwards continuously, the pull rod 83 drives the cabinet body 1 to move forwards continuously, the two rear universal wheels 19 of the cabinet body 1 cross the ground and raise under the continuous push and pull of the front and rear two people, and therefore the cabinet body 1 is raised above the ground.

When the two universal wheels 19 on the rear side of the cabinet body 1 meet with the ground bulge, the cabinet body 1 cannot topple over due to the fact that the gravity center of the cabinet body 1 already crosses the ground bulge and is supported by the two universal wheels 19 on the front side.

When the cabinet body 1 is moved to a destination place, the pull rod 83 is pressed down, the pull rod 83 drives the two slide rods 23 to slide downwards to the limit positions outside the corresponding guide sleeves A20 through the two guide rods 41 and the guide sleeves B26, the springs A22 in the slide rods 23 are stretched to the initial state, meanwhile, the push handle 55 is horizontally pulled to the initial state outside the cabinet body 1, and the limit grooves C56 on the push handle 55 are opposite to the corresponding limit rods C52 again.

In the process that the sliding rod 23 slides out of the guide sleeve A20, the sliding rod 23 drives the vertical part of the trigger rod 33 to vertically move towards each other in the sliding groove I31 of the corresponding limiting rod A30. When the sliding rod 23 slides in the guide sleeve a20 to an initial state, the limiting groove a24 on the sliding rod 23 is opposite to the limiting rod a30 again, the limiting rod a30 is inserted into the limiting groove a24 instantly under the reset action of the corresponding spring B32 and limits the sliding of the sliding rod 23 in the guide sleeve a20, the pull rope 50 connecting the limiting rod a30 and the limiting rod C52 is loosened, the limiting rod C52 is inserted into the limiting groove C56 on the push handle 55 instantly under the reset action of the corresponding spring D53 and limits the sliding of the push handle 55 into the cabinet 1, and the pull rope 50 is stretched straight again. The limiting rod A30 drives the trigger rod 33 to reset relative to the slide rod 23 in the process of being inserted into the limiting groove A24 on the slide rod 23, and the trigger rod 33 drives the trigger plate 34 to reset and restore the relative state with the universal wheel 19.

Then, the two shift levers 45 are shifted oppositely, the two shift levers 45 respectively drive the corresponding limiting rods B43 to separate from the limiting grooves B42 on the corresponding guide rods 41 and release the sliding limitation of the guide rods 41 in the guide sleeves B26, and the spring C46 is further compressed. The pull rod 83 swings around the round pin 37 to the U-shaped groove 5 at the front side of the cabinet 1 under the reset action of the two scroll springs 40, then the acting force on the two shift levers 45 is removed, and the two limit rods C52 instantly abut against the side walls of the corresponding guide rods 41 respectively under the reset action of the corresponding springs C46.

By reversely rotating the rotating shaft D71 with a hexagonal wrench, the rotating shaft D71 drives the four supporting rods 59 to abut against the ground again through a series of transmissions, so that the four supporting rods 59 assist the four universal wheels 19 to effectively support the cabinet 1 again. At this point, the horizontal movement of the cabinet 1 is finished.

In conclusion, the beneficial effects of the invention are as follows: the four support rods 59 are driven by rotating the rotating shaft D71 to assist the four universal wheels 19 to effectively support the standing cabinet, so that the universal wheels 19 are prevented from being damaged due to the fact that the cabinet is too heavy.

During the movement of the invention, which is pushed and pulled by two persons in tandem, the trigger plate 34 of the invention interacts with the ground projection before the universal wheel 19 meets the ground projection, so that the contraction limitation of the sliding rod 23 on the guide sleeve A20 and the sliding limitation of the limiting rod C52 on the grip are released, so that the pull rod 83 instantaneously swings downwards by a certain extent around the round pin 37 on the slide rod 23 under the pulling of a person in front, meanwhile, the push handle 55 is pushed by the person behind to contract into the cabinet to a certain extent, so that the force of pushing and pulling of the front and the back people is instantaneously reduced to generate the shimmering caused by the instantaneous force dissipation, thereby reminding the front and rear persons that if the universal wheels 19 are continuously moved forward and the equipment is touched with the ground bulge, and then remind two people to stop pushing and pulling equipment and lift up equipment through pull rod 83 and cross the arch, avoid equipment to remove the in-process because of universal wheel 19 touches the arch and takes place to empty.

When the device needs to be lifted for carrying, the two lifting rods are pulled to slide out through the pull ring 79, and simultaneously the two lifting rods A73 synchronously slide out, so that the device is lifted in a way of lifting the bridal sedan chair. Compared with the traditional mode of lifting the equipment through the equipment side wall groove, the bridal sedan chair type lifting equipment is more convenient to lift and provides a force application point for lifting the equipment by more people.
