[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0027] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0028] Example 1

[0029] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a component elevator, which includes a carrying unit 1, and the carrying unit 1 includes two parallel support rods 11; wherein, the top of the support rod 11 is provided with a first through hole 111, two fixed cylinders 113 symmetrically arranged at the bottom of the support rod 11, and a connecting groove 112 for connecting the first through hole 111 and the two fixed cylinders 113, and two symmetrical placement grooves 114 are provided inside the support rod 11.

[0030] The carrying unit 1 provides a supporting foundation for the device and also supports the installation of other components. The setting of the support rod 11 provides support for the device, and the first through hole 111 can be connected to the transmission unit 4. The transmission unit 4 can compress the gas in the first through hole 111, and the pressure is transmitted to the fixed cylinder 113 through the action of the connecting groove 112, thereby achieving the squeezing of the telescopic support leg 17.

[0031] The telescopic support leg 17 and the fixed cylinder 113 are connected by a piston, and the two can slide tightly together. A sealing ring can also be set at the position of the outer ring of the top of the telescopic support leg 17 and the base of the inner wall of the fixed cylinder 113 to enhance the sealing between the two.

[0032] The arrangement of the placement groove 114 can provide installation conditions for the turntable 5 .

[0033] The transmission unit 4 is installed above the support rod 11 and is connected to the first through hole 111;

[0034] Through the setting of the transmission unit 4, when the power unit 2 drives the supporting unit 3 to move, it can also drive the transmission unit 4 to operate. During the operation, the gas in the transmission unit 4 will be compressed, and the movement of the telescopic support leg 17 will be realized through the communication between the first through hole 111, the connecting groove 112 and the fixed cylinder 113.

[0035] The turntable 5 rotates and is placed in the groove 114, and the connection between the turntable 5 and the placement groove 114 is sealed.

[0036] By rotating the turntable 5, the operating state of the device can be changed. Elastic sealing pads are provided on both sides of the turntable 5, which can ensure that any part of the side of the turntable 5 can fit tightly with the placement groove 114 to ensure sealing, while also ensuring that the turntable 5 can rotate in the placement groove 114.

[0037] Example 2

[0038] Reference Figures 2 to 9 , which is the second embodiment of the present invention, is different from the first embodiment in that it also includes two support rods 11 fixedly connected by a connecting plate 12, rollers 16 are installed at both ends of the bottom of the support rods 11, and a telescopic support foot 17 is slidably provided in the fixed cylinder 113.

[0039] The connection of the connecting plate 12 ensures the supporting strength of the entire device. Multiple connecting plates 12 can also be set, and the specific setting can be based on actual conditions. No specific limitation is made here. The setting of the roller 16 facilitates the movement of the device, and it is convenient to move the device to the bottom of the object to be lifted. When not in use, it is also convenient to move the device to an area that does not hinder the staff.

[0040] Specifically, a U-shaped plate 13 is symmetrically fixedly connected to the top of the connecting plate 12 , a mounting plate 14 is fixedly connected to the top of the U-shaped plate 13 , and a second through hole 15 is opened in the mounting plate 14 corresponding to the center of the opening of the U-shaped plate 13 .

[0041] By setting the U-shaped plate 13 and the mounting plate 14, the power unit 2 is provided with installation conditions, and the movement of the supporting unit 3 is limited to ensure stable movement under the drive of the power unit 2. The height of the U-shaped plate 13 can be set according to actual usage. The height of the U-shaped plate 13 is the height at which objects can be lifted. The second through hole 15 is set to allow the sleeve 41 to slide therein, ensuring the normal operation of the transmission unit 4.

[0042] Specifically, the transmission unit 4 includes a sleeve 41 disposed above the mounting plate 14 , a piston rod 42 sliding inside the sleeve 41 , and a connecting pipe 44 fixed to the top end of the sleeve 41 .

[0043] Furthermore, one end of the piston rod 42 passing through the second through hole 15 and located in the U-shaped plate 13 is fixedly connected to the movable plate 43 , and one end of the connecting pipe 44 is communicated with the first through hole 111 .

[0044] When the power unit 2 drives the supporting unit 3 to move, the supporting unit 3 drives the piston rod 42 to move through the moving plate 43. During the movement, the end of the piston rod 42 located in the sleeve 41 fits tightly against the inner wall of the sleeve 41 to form a seal. When the piston rod 42 is moved, the gas in the sleeve 41 is squeezed, and the squeezing force is transmitted to the connecting groove 112 through the connecting pipe 44, and finally transmitted to the telescopic support leg 17, pushing the telescopic support leg 17 out to support the entire device.

[0045] A sealing ring may be added to the portion where the piston rod 42 contacts the inner wall of the sleeve 41 to enhance the sealing performance of the portion.

[0046] Specifically, a third through hole 51 and a groove 52 are defined on the turntable 5 . The size of the third through hole 51 is the same as that of the communicating groove 112 . The groove 52 is located on one side close to the middle of the support rod 11 .

[0047] The turntable 5 is arranged in the placement groove 114, and the upper part of the turntable 5 and the part located on the side of the support rod 11 away from the connecting plate 12 both penetrate the support rod 11, but due to treatment such as sealing gaskets, no leakage will occur. The sealing here is an existing technology and will not be elaborated on.

[0048] The turntable 5 can provide three states as follows:

[0049] State 1: If Figure 7As shown, at this time, the third through hole 51 and the connecting groove 112 are located on the same axis. At this time, when the piston rod 42 moves, the gas will pass through the connecting groove 112 through the third through hole 51 to push the telescopic support leg 17, thereby limiting the device while lifting the heavy object, so that it will not move, ensuring the safety of the staff during maintenance or other operations. In addition, the sides of the turntable 5 are sealed with the placement groove 114, so there will be no leakage, which is suitable for normal operation.

[0050] State 2: When the telescopic legs 17 are lifted up, the turntable 5 is rotated. The state after rotation is as follows: Figure 8 As shown, at this time, the third through hole 51 is separated from the connecting groove 112, and the turntable 5 now isolates the connecting groove 112. After isolation, the position from the connecting groove 112 to the fixed cylinder 113 is in a closed state. In the closed state, the stability of the telescopic support leg 17 can be ensured and it will not move. Both ends of the connecting groove 112 in the middle are connected to the groove 52, and the groove 52 is connected to the outside world in order to change the pressure inside the connecting groove 112. At this time, while ensuring the stable support of the telescopic support leg 17, the supporting unit 3 can also be moved. This is suitable for the situation where the supporting unit 3 needs to be moved after the telescopic support leg 17 is stably supported.

[0051] Furthermore, when rotating, due to the sealing conditions, the force used for rotation is relatively large, and a jack can be opened on the outer ring of the turntable 5 to insert a rod, which can reduce the force used by the staff and ensure normal manual operation.

[0052] State 3: Continue to rotate the turntable 5 to reach Figure 9 The state shown can completely isolate the connecting groove 112. At this time, both sides of the isolation of the connecting groove 112 are sealed. First, the same as state two, it can ensure the stability of the telescopic support leg 17; second, it can also be sealed with the sleeve 41. At this time, the heavy object placed on the supporting unit 3 is fixed by the action of the power unit 2. The power unit 2 is subjected to a large force, and the blocking of the connecting groove 112 can give the piston rod 42 a stable force to ensure that it does not move. It can also generate a certain pulling force on the supporting unit 3 to reduce the force exerted on the power unit 2. Compared with state one, state one can also be achieved, but because the connecting plate 12 is connected, the telescopic support leg 17 is supported, and the gravity exerted on the supporting unit 3 will act on the power unit 2, which greatly increases the force on the power unit 2 and may reduce the service life of the power unit 2. It is suitable for static and non-operational situations.

[0053] For the above three states, a mark can be made on the outer ring of the turntable 5. When the mark is rotated to a suitable position corresponding to the support rod 11, it indicates that the state switching is completed.

[0054] After the device is used, the state can be adjusted by rotating the dial 5 and turning on the power unit 2 to adjust the device to the initial state so as not to affect the next use.

[0055] Furthermore, if there is air in the sleeve 41, the connecting pipe 44, and the communicating groove 112, the above steps can be performed; if there is hydraulic liquid in the sleeve 41, the connecting pipe 44, and the communicating groove 112, then the sealing of the device also meets the conditions, but it is necessary to further set a liquid storage tank at the position of the upper opening of the turntable 5 at the support rod 11, so that the hydraulic liquid can flow in or out at will without affecting the normal operation of the device.

[0056] When in use, the supporting unit 3 is first driven to move by the power unit 2, and the supporting unit 3 drives the piston rod 42 to move through the moving plate 43. When moving, since the end of the piston rod 42 in the sleeve 41 is tightly fitted with the inner wall of the sleeve 41 to form a seal, when the piston rod 42 is moved, the gas in the sleeve 41 will be squeezed, and the squeezing force will be transmitted to the connecting groove 112 through the connecting pipe 44, and finally transmitted to the telescopic support leg 17, pushing the telescopic support leg 17 out to support the entire device. During the process, the turntable 5 can be rotated as needed to switch between the three states.

[0057] Example 3

[0058] Reference Figures 2 and 3 , which is the third embodiment of the present invention, is based on the previous two embodiments and further includes a power unit 2, which includes a motor 21 installed on the top of the mounting plate 14, and the output end of the motor 21 is fixedly connected to a threaded rod 22, and one end of the threaded rod 22 rotates on the top of the connecting plate 12.

[0059] The motor 21 provides power for the device. The motor 21 drives the threaded rod 22 to rotate, which can drive the supporting unit 3 to move, ensuring the lifting and lowering of the object.

[0060] Specifically, it also includes a supporting unit 3, which includes two brackets 31 symmetrically arranged on both sides of the U-shaped plate 13. The two brackets 31 are fixedly connected by an internal threaded plate 33 and a connecting block 32, and the internal threaded plate 33 is threadedly matched with the threaded rod 22.

[0061] Furthermore, a fixing block 34 is provided on the inner side of the bracket 31 . An arcuate groove 35 is formed at one end of the fixing block 34 . The arcuate groove 35 is in sliding engagement with the piston rod 42 .

[0062] Furthermore, the fixing block 34 and the connecting block 32 are both disposed in the U-shaped plate 13 , and the movable plate 43 is located between the fixing block 34 and the connecting block 32 .

[0063] The two symmetrically arranged brackets 31 can lift two objects at the same time, and can also lift larger and easily foldable objects. Lifting both sides at the same time can also prevent one side from tipping over due to excessive weight, causing damage to the object.

[0064] By setting the connecting block 32 and the internal thread plate 33, the connection strength between the two brackets 31 is increased, and the two brackets 31 and the connecting block 32 and the internal thread plate 33 are detachable, which is convenient for installation and disassembly between devices, and also convenient for replacement or maintenance of components therein.

[0065] The internal threaded plate 33 can be threadedly matched with the threaded rod 22. When the motor 21 drives the threaded rod 22 to rotate, it can drive the internal threaded plate 33 to move upward or downward, and the fixed block 34 and the connecting block 32 slide in the U-shaped plate 13. While sliding, they can drive the piston rod 42 to move through the movable plate 43. The arc groove 35 also provides conditions for the placement of the piston rod 42.

[0066] When in use, the motor 21 is turned on to drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, it can drive the internal threaded plate 33 to move. When the internal threaded plate 33 moves, it drives the supporting unit 3 to move, thereby driving the piston rod 42 to move, ensuring the normal operation of the device.

[0067] In summary, when in use, first move the device to the device to be lifted, then move the motor 21 to drive the threaded rod 22 to rotate, thereby driving the bracket 31 to lift the object, and through the transmission effect of the transmission unit 4 and the support rod 11, drive the telescopic support leg 17 to move downward. When the object is lifted to the moving height and the telescopic support leg 17 is not in contact with the ground, turn off the motor 21. By pushing the device, the object can be moved. After moving to the appropriate position, turn on the motor 21 and continue to drive the bracket 31 to move until the telescopic support leg 17 lifts the device. Turn off the motor 21, and then control the rotation of the turntable 5 as needed, switching between three states to ensure stability during use.

[0068] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
