Description

Technical Field

[0002] Lifting platforms are widely used in medical equipment. For example, when the medical equipment is a medical imaging system, radiation from a radiation source is directed toward an object to be detected, which is usually a patient in a medical diagnosis application. A portion of the radiation passes through the object to be detected and is received by a detector, which generates an output signal based on the amount or intensity of radiation received by the detector. The output information is processed to generate a medical image that can be displayed for inspection.

[0003] For the supine scanning method, usually, the object to be detected needs to lie on a lifting platform in a supine position. The lifting platform includes a base and a support platform arranged on the upper side of the base. A support assembly is arranged between the base and the support platform, and the support assembly drives the support platform to move so as to move the object to be detected located on the support platform to a desired position.

[0033] In an embodiment of the present application, the lifting platform can be applied to various devices. The device includes, for example, medical equipment, or industrial equipment. Taking medical equipment as an example, the medical equipment includes, for example, equipment related to various medical imaging scenarios. The medical imaging scenarios include, but are not limited to, magnetic resonance imaging (MRI), computed tomography (CT), ultrasound imaging, X-ray imaging, positron emission tomography (PET), single photon emission computed tomography (SPECT), PET / CT, PET / MR or any other suitable medical imaging scenarios.

[0034] In the embodiments of the present application, the lifting platform and medical equipment of the present application are exemplarily described by taking the CT scene as an example. Those skilled in the art will understand that the present application is also applicable to other radiation imaging systems or imaging systems based on other high-frequency electromagnetic energy.

[0035] Figure 1 FIG. 1 is a schematic diagram of a CT system for CT imaging according to an embodiment of the present application. Figure 1 As shown, the CT system 100 is used to image a scan object 112 (eg, a patient, an inanimate object, an implant, a stent and / or a contrast agent present in the body, etc.).

[0036] The CT system 100 includes a lifting platform 101. A scanning object 112 lies on the lifting platform 101. The lifting platform 101 drives the object 112 to move, for example, along Figure 1 At least one of the coordinate axes X, Y, and Z in the image is displaced.

[0037] The CT system 100 includes a gantry 102. An X-ray source 104 is mounted on the gantry 102 and is used to emit an X-ray beam 106 for imaging a scan object 112. Specifically, the X-ray source 104 is used to project the X-ray beam 106 toward a detector assembly 108 positioned on the opposite side of the gantry 102.

[0038] In some embodiments, the X-ray source 104 emits a fan-shaped / conical beam of rays, which is collimated into an XYZ plane located in a Cartesian coordinate system, i.e., an imaging plane. The X-ray beam passes through the scanned object 112 and is attenuated by the scanned object 112 before being projected onto the detector assembly 108. Therefore, the intensity of the rays received on the detector assembly 108 depends on the attenuation degree of the rays by the scanned object 112. The detector assembly 108 may include a plurality of detector units forming an array, each of which detects a signal representing the intensity of the corresponding beam of rays. The signals detected by each detector unit may be used as distributed projection data (or image data) for subsequent processing.

[0039] In some embodiments, the CT system 100 further includes an image reconstructor 110, which is used to receive the projection data and perform image reconstruction to obtain a volume image of the scanned object 112, which may specifically include a three-dimensional volume image or an image corresponding to one or more two-dimensional slices of the scanned object 112. The reconstructed image may be transmitted to a processing device and stored in a large-capacity memory coupled to the processing device.

[0040] Figure 2 is another schematic diagram of a CT system for CT imaging according to an embodiment of the present application. Figure 2 The CT system 200 shown is Figure 1 The CT system 100 shown is similar. Figure 2 As shown, the CT system 200 is used to scan an object 204 (eg Figure 1 The scanned object 112) is imaged.

[0041] The CT system 200 includes a detector assembly 108, which includes a plurality of detector units 202 that collectively detect an X-ray beam 106 that passes through a scanned object 204 to acquire corresponding projection data. In one example, the detector assembly includes a plurality of rows of detector units 202 that can be used to acquire projection data corresponding to a plurality of slices. The detector units 202 can be energy integrating detectors, photon counting detectors, energy discriminating detectors, or any other suitable radiation detectors. The detector units 202 can employ scintillators and generate analog signals, and the detector units 202 can also be direct conversion detectors (i.e., detectors that do not employ scintillation), such as detectors based on silicon strips or other semiconductor materials, which generate measurable signals when the semiconductor sensors themselves are exposed to X-rays.

[0042] In some embodiments, the CT system 200 further includes a beam limiter assembly 220, which can be positioned in the propagation direction of the X-ray source 104 and adjacent to the X-ray source, and the beam limiter assembly 220 can limit the shape and / or range of the high-intensity region of the X-ray beam 106 to limit the X-ray exposure of the portion outside the region of interest of the scanned object 204. Specifically, the beam limiter assembly 220 can be installed between the X-ray source 104 and the scanned object 204 and positioned close to the X-ray source 104. The beam limiter assembly 220 can include one or more blades (or baffles), the one or more blades forming an opening, the one or more blades being used to block a portion of the X-rays, and the opening being used to pass another portion of the rays, thereby limiting the shape and / or range of the projected X-ray beam.

[0043] In some embodiments, the CT system 200 may further include a collimator (not shown), which may be disposed between the scanned object 204 and the detector assembly 208 and adjacent to the detector assembly 208. The collimator is generally made of a material that blocks or absorbs X-rays, so that the X-rays reflected or deflected by the scanned object 204 can be blocked by the collimator to prevent them from being projected to the detector assembly 208. On the contrary, the X-rays 106 traveling in a relatively straight path from the X-ray source 104 to the detector assembly 208 are not blocked by the collimator 222 and can be projected to the detector assembly 208.

[0044] In some embodiments, the CT system 200 further includes a control mechanism 208, which may include an X-ray controller 210 and a gantry motor controller 212. During a scan to acquire projection data, the X-ray controller 210 is used to control the operation of the X-ray source 104 (e.g., providing power and timing signals to the X-ray source 104, and determining / tracking the focus / focal spot position of the X-ray source), and the gantry motor controller 212 is used to control the gantry 102 and components mounted thereon to rotate around the scanned object 112 at an appropriate speed based on imaging requirements, so that the angle / position at which the X-ray beam 106 intersects the scanned object 112 is constantly changing. The projection data acquired by the detector assembly 108 at each angle is called a view, and a scan performed on the scanned object 112 includes a set of views obtained at different angles during one rotation of the X-ray source 104 and the detector assembly 108 around the scanned object 112.

[0045] In some embodiments, the control mechanism 208 further includes a lift motor controller 215, which can further control the lift 228 (eg, Figure 1 Specifically, the lifting platform motor controller 215 can move the lifting platform 228 so that the scanning object 204 on the lifting platform 228 moves completely or partially through Figure 1 The opening of the gantry 102 is opened to position the scan object 204 in a scan area defined by the gantry 102 to acquire projection data corresponding to the scan object 204.

[0046] In some embodiments, the control mechanism 208 further includes a beam limiter assembly controller 213, which is used to control the operation of the beam limiter assembly 220. For example, the movement of one or more blades of the beam limiter assembly 220 (or the beam limiter assembly 300 described below) can be controlled to adjust the position or width of the opening. In some embodiments, such adjustment can be performed based on the result of the X-ray controller 210 tracking the focus of the X-ray source.

[0047] The detector array composed of the detector units 202 includes a full shadow area for receiving full shadow data and a penumbra area for receiving penumbra data. When the X-ray source 104 emits an X-ray beam 106 at different focal spot positions, the full shadow area can receive the X-ray beams at all focal spot positions, while the penumbra area may only receive the X-ray beams emitted at a portion of the focal spot positions. In some embodiments, the full shadow area is usually formed into a regular array (e.g., a rectangle) to adapt to the shape of the X-ray beam limited by, for example, a beam limiter assembly 220 having a square opening. In order to track the focal spot position, it is necessary to set an additional small number of detectors at the edge portion outside the regular array to form the above-mentioned penumbra area, so that an irregular shape is formed as a whole, and the design cost is relatively high.

[0048] In some embodiments, the CT system 200 further includes a data acquisition system (DAS) 214 for sampling and digitizing data received by the detector unit 202 to convert it into projection data. The data sampled and digitized by the DAS 214 is transmitted to a processing device 216 as further described herein.

[0049] The processing device 216 may include a computer device. In one example, the processing device 216 stores data in a storage device or mass storage 218, or the data sampled and digitized by the DAS 214 is directly transferred to the mass storage 218. For example, the storage device 218 may include a hard drive, a floppy drive, a compact disk-read / write (CD-R / W) drive, a digital versatile disk (DVD) drive, a flash drive, and / or a solid-state storage drive, etc. An associated display 232 allows an operator to observe reconstructed images and other data from the processing device. The display 232 may also allow an operator to select a region of interest and / or request patient information via a graphical user interface for subsequent processing.

[0050] In some embodiments, the CT system 200 further includes an operator console 234, which is operably coupled to the processing device 216, and the processing device 216 can receive instructions and parameters input by the operator through the operator console 234. The operator console has some form of operator interface, such as a keyboard, a mouse, a voice-activated controller, or any other suitable input device.

[0051] In addition, the processing device 216 is used to send commands or parameters to one or more of the DAS 214, the X-ray controller 210, the gantry motor controller 212, the beam limiter assembly controller 213, and the elevator motor controller 215 to control system operations, such as data acquisition and / or processing. The processing device 216 can control system operations based on operator input.

[0052] In some embodiments, the processing device 216 may calculate parameters (e.g., Z ratio) for tracking the focus of the X-ray source 104 based on the penumbra data and the full shadow data in the data received from the DAS, and send the parameters to the X-ray controller 210, and the X-ray controller 210 tracks the focus position of the X-ray source 104 based on the received parameters (e.g., Z ratio). The processing device 216 may also receive the result of the focus tracking from the X-ray controller 210, and send it to the beam limiter assembly controller 213, so as to be able to control the operation of the beam limiter assembly 220 (or the beam limiter assembly 300) based on the current focus position.

[0053] In some embodiments, the CT system 200 includes an image reconstructor 230, which is used to receive projection data from the DAS 214 and perform image reconstruction, and the reconstructed image can be transmitted to the processing device 216 to generate patient information for diagnosis and evaluation. The processing device 216 is used to store the reconstructed image and patient information in a large-capacity memory 218. In some embodiments, the processing device 216 can transmit the reconstructed image to a display 232, which can be communicatively coupled to the processing device 216 and / or the image reconstructor 230.

[0054] The above only describes an example of a CT system suitable for applying the embodiments of the present application. Those skilled in the art will recognize that the embodiments of the present application can also be applied to any imaging system or device based on other radiation or high-frequency electromagnetic energy.

[0055] Figure 3 Schematic diagram of a lifting platform according to an embodiment of the present application. Figure 3 As shown, the lifting platform 300 includes a base 301 , a support platform 302 , a support assembly 303 , a locking assembly 304 , and a locking state switching member 305 .

[0056] like Figure 3 As shown, the support platform 302 is disposed on the upper side of the base 301. The support assembly 303 connects the support platform 302 and the base 301, and drives the support platform 302 to rise and fall.

[0057] The locking assembly 304 includes a main body 3041 connected to the supporting assembly 303, and a blocking member 3042 movably mounted on the main body 3041. The blocking member 3042 blocks the movement of the supporting assembly 303 when it moves to a first position against the base 301.

[0058] The locking state switching member 305 is detachably connected to the locking assembly 304. When the locking state switching member 305 is removed from the locking assembly 304, the blocking member 3042 moves to the first position.

[0059] According to the above embodiment, a locking assembly 304 capable of preventing the movement of the supporting assembly 303 of the lifting platform 300 and a locking state switching member 305 detachably connected to the locking assembly 304 are provided in the lifting platform 300. When the locking state switching member 305 is removed from the locking assembly 304, the locking assembly 304 prevents the movement of the supporting assembly 303. Thus, the user only needs to remove the locking state switching member 305 from the locking assembly 304 to lock the lifting platform 300, that is, the lifting platform 300 is locked by a removal operation rather than an installation operation. Thus, the locking operation can be simplified, which helps to avoid safety problems.

[0060] In some embodiments, Figure 3 As shown, the lifting platform 300 may further include a component shielding member 306 for repair. The component shielding member 306 for repair covers or shields at least a portion of the component to be repaired of the lifting platform 300. The locking state switching member 305 is used to release the component shielding member 306 from covering or shielding the component to be repaired.

[0061] According to the above structure, the shielding member 306 of the component to be repaired is used to cover or shield the component to be repaired, wherein the locking state switching member 305 is required to release the covering or shielding of the component to be repaired by the shielding member 306 of the component to be repaired. That is to say, if the user wants to repair the component to be repaired, it is necessary to first release the covering or shielding of the component to be repaired by the shielding member 306 of the component to be repaired; if the covering or shielding is to be released, it is necessary to first remove the locking state switching member 305 from the locking assembly 304. As mentioned above, after the locking state switching member 305 is removed, the locking assembly 304 locks the lifting platform 300, thereby preventing the support platform 302 from unexpected displacement or decline. Therefore, through the above structure, the lifting platform 300 can be reliably locked before the component to be repaired, thereby realizing the poka-yoke function, providing reliable safety protection, and effectively avoiding safety problems.

[0062] In some embodiments, Figure 3 As shown, the component to be repaired of the lifting platform 300 may be a driving component 307 for driving the support component 303 to move. Thus, before the driving component 307 is repaired or replaced, it can be ensured that the lifting platform 300 is in a locked state, so that the support platform 302 will not suddenly drop due to the repair or removal of the driving component 307. The present application is not limited thereto, and the component to be repaired may also be other components of the lifting platform 300.

[0063] The driving component 307 is, for example, a cylinder, a hydraulic cylinder, a linear actuator, or a ball screw.

[0064] like Figure 3 As shown, the support assembly 303 can be in the form of a scissor arm. For example, the support assembly 303 includes a first arm 3031 and a second arm 3032 arranged crosswise, and a shaft 3033 connecting the first arm 3031 and the second arm 3032. The first arm 3031 and the second arm 3032 can rotate around the shaft 3033.

[0065] The upper ends of the first arm 3031 and the second arm 3032 are connected to the support platform 302, and the lower ends of the first arm 3031 and the second arm 3032 are connected to the base 301 and the driving component 307. The driving component 307 drives the lower end of at least one of the first arm 3031 and the second arm 3032 to move, and adjusts the height of the upper end of the first arm 3031 and the upper end of the second arm 3032 by adjusting the distance between the lower end of the first arm 3031 and the lower end of the second arm 3032, thereby adjusting the height of the support platform 302.

[0066] The above is merely an exemplary description of the manner in which the driving assembly 307 drives the supporting assembly 303 , wherein the driving assembly 307 may also drive the supporting assembly 303 in other manners, and the present application does not impose any specific limitation on this.

[0067] In some embodiments, the component to be repaired shielding member 306 may be any structure capable of covering or shielding the component to be repaired. For example, the component to be repaired shielding member 306 may be a shell, thereby reliably covering or shielding the component to be repaired.

[0068] Figure 4 Schematic diagram of a partial structure of a lifting platform according to an embodiment of the present application. Figure 4 As shown, the lifting platform 300 may further include a fixing member 308. The fixing member 308 is connected to the component shielding member 306 to fix the component shielding member 306 to cover or shield at least a part of the component to be repaired.

[0069] like Figure 4 As shown, the fixing member 308 can be any structure capable of fixing the cover member 306 of the component to be repaired. For example, the fixing member 308 can be a screw, and the cover member 306 of the component to be repaired can be a shell, a through hole matching the screw is provided on the shell, and a hole matching the screw is provided at a specified position of the base 301, and the screw is provided in the hole of the base 301 through the through hole, so that the cover member 306 of the component to be repaired can be fixed at a position covering or shielding at least a part of the component to be repaired. The present application is not limited to this, and the fixing member 308 can also fix the cover member 306 of the component to be repaired in other ways.

[0070] In some embodiments, the locking state switching member 305 is used to release the connection between the fixing member 308 and the repaired component shielding member 306. For example, the locking state switching member 305 can be a tool that matches the fixing member 308. For example, the fixing member 308 is a screw, and the locking state switching member 305 is a wrench.

[0071] Figure 5 is another schematic diagram of the partial structure of the lifting platform of the embodiment of the present application. Figure 4 and Figure 5 As shown, the locking state switching member 305 ( Figure 5 The number of the fixing member 308 (shown in FIG. 1 ) may be one or more. Figure 4 The number of (shown in ) can be one or more. Among them, one locking state switching component 305 can correspond to one fixing component 308 (referred to as one-to-one), that is, one locking state switching component 305 can be used to release the connection between the corresponding fixing component 308 and the shielding component 306 of the component to be repaired; or, multiple locking state switching components 305 can correspond to one fixing component 308 (referred to as many-to-one), that is, it is necessary to use the multiple locking state switching components 305 to work together to release the connection between the corresponding fixing component 308 and the shielding component 306 of the component to be repaired; or, one locking state switching component 305 can correspond to multiple fixing components 308 (referred to as one-to-many), that is, the one locking state switching component 305 can release the connection between the corresponding multiple fixing components 308 and the shielding component 306 of the component to be repaired; or, multiple locking state switching components 305 can correspond to multiple fixing components 308 (referred to as many-to-many), that is, the multiple locking state switching components 305 can work together to release the connection between the corresponding multiple fixing components 308 and the shielding component 306 of the component to be repaired.

[0072] In some embodiments, Figure 5 As shown, the locking assembly 304 may include one or more blocking members 3042. When the locking assembly 304 includes multiple blocking members 3042 and the number of the locking state switching members 305 is multiple, when one locking state switching member 305 is removed from the locking assembly 304, at least one blocking member 3042 moves to the first position against the base 301. Thus, when the locking state switching member 305 is removed, the locking assembly 304 can reliably abut against the base 301, so that the lifting platform 300 can be reliably locked.

[0073] The following is a specific example to illustrate the corresponding relationship between the plurality of blocking members 3042, the plurality of locking state switching members 305 and the plurality of fixing members 308. Figure 5 As shown, the locking state switching member 305 includes a first locking state switching member 305-1 and a second locking state switching member 305-2; Figure 4As shown, the fixing member 308 includes a first fixing member 308-1 and a second fixing member 308-2. The first locking state switching member 305-1 is used to release the connection between the first fixing member 308-1 and the shielding member 306 of the component to be repaired, and the second locking state switching member 305-2 is used to release the connection between the second fixing member 308-2 and the shielding member 306 of the component to be repaired. In other words, the first locking state switching member 305-1 and the second locking state switching member 305-2 need to release the first fixing member 308-1 and the second fixing member 308-2 respectively before the shielding member 306 of the component to be repaired can be released from covering or shielding the component to be repaired. Therefore, it is possible to avoid the accidental removal of the shielding member 306 of the component to be repaired.

[0074] like Figure 5 As shown, the locking assembly 304 includes a first blocking member 3042-1 and a second blocking member 3042-2. The first blocking member 3042-1 is movably mounted on the first main body 3041-1, and the second blocking member 3042-2 is movably mounted on the second main body 3041-2. When the first locking state switching member 305-1 is removed from the locking assembly 304, the first blocking member 304-1 abuts against the base 301, and when the second locking state switching member 305-2 is removed from the locking assembly 304, the second blocking member 304-2 abuts against the base 301.

[0075] In some embodiments, the first fixing member 308-1 and the second fixing member 308-2 can be screws with different head diameters. For example, the first fixing member 308-1 is a screw with a head diameter of 4 mm, and the second fixing member 308-2 is a screw with a head diameter of 5 mm. The first locking state switching member 305-1 and the second locking state switching member 305-2 are wrenches that match the sizes of the first fixing member 308-1 and the second fixing member 308-2, respectively.

[0076] In some embodiments, the first body portion 3041-1 and the second body portion 3041-2 are respectively connected to different positions of the lower end of the support assembly 303, for example, they are respectively connected to both sides of a direction perpendicular to the moving direction of the lower end of the support assembly 303 (for example, the front-to-back direction). Thus, the movement of the support assembly 303 can be blocked at both sides of the support assembly 303, thereby improving the reliability of locking.

[0077] like Figure 5 As shown, the base 301 can be provided with a plurality of grooves E along the moving direction of the lower end of the supporting assembly 303 , and the blocking member 304 can be engaged with any groove E. Thus, no matter where the lower end of the supporting assembly 303 is located, the lifting platform 300 can be locked by the locking assembly 304 .

[0078] The structure of the locking assembly is exemplarily described below with reference to the accompanying drawings. Figure 6a and Figure 6b is a schematic diagram of a locking assembly and a locking state switching member according to an embodiment of the present application, Figure 7 is a schematic diagram of a locking assembly according to an embodiment of the present application. Figure 6a and Figure 6b As shown, the main body 3041 of the locking assembly 304 is provided with a through hole A, which extends along the moving direction of the blocking member 3042 and is used to accommodate at least a portion of the blocking member 3042.

[0079] In some embodiments, when the locking state switching member 305 is connected to the locking assembly 304, the blocking member 3042 moves to a second position that does not abut against the base 301. Figure 6a As shown, the second position is, for example, a position where the lower end (second end) of the blocking member 3042 is received in the through hole A.

[0080] Accordingly, if Figure 7 As shown, the first position where the blocking member 3042 abuts against the base 301 may be a position where the lower end (second end) 3042-B of the blocking member 3042 is exposed from the main body 3041. In the first position, the upper end (first end) 3042-A of the blocking member 3042 may abut against the main body 3041 to prevent the blocking member 3042 from sliding out of the through hole A. The present application is not limited thereto, and other structures may be used to prevent the blocking member 3042 from sliding out of the through hole A.

[0081] In some embodiments, Figure 6a and Figure 6b As shown, when the locking state switching member 305 is connected to the locking assembly 304, the locking state switching member 305 is engaged with the blocking member 3042. Thus, the blocking member 3042 can be kept in the second position where it does not abut against the base 301.

[0082] In some embodiments, Figure 6b As shown, the blocking member 3042 may include a snap-fit ​​portion 3042-C that snaps into the locking state switching member 305. The snap-fit ​​portion 3042-C may be a groove disposed on the surface of the blocking member 3042 or a hole disposed in the blocking member 3042.

[0083] Taking the engaging portion 3042-C as a groove as an example, the groove can extend along the circumference of the blocking member 3042. For example, the groove can be set within the entire circumference of the blocking member 3042. Therefore, no matter at which spin angle the blocking member 3042 is accommodated in the through hole A, a part of the groove can be engaged with the locking state switching member 305, which facilitates the installation and manufacture of the blocking member 3042.

[0084] The present application is not limited thereto, and the groove may also be provided within a partial range of the circumference of the blocking member 3042. In this case, the blocking member 3042 needs to be accommodated in the through hole A at a predetermined rotation angle so that the groove is located at a position capable of engaging with the locking state switching member 305.

[0085] In some embodiments, a mark can be set on the blocking member 3042 to identify the spin angle of the blocking member 3042, or the blocking member 3042 and the through hole A can be set to a non-axisymmetric shape to ensure that the blocking member 3042 is always accommodated in the through hole A at a specified spin angle.

[0086] The position of the groove in the up-down direction of the blocking member 3042 may be such that when the locking state switching member 305 is engaged with the groove, the lower end of the blocking member 3042 does not abut against the base 301 .

[0087] Taking the engaging portion 3042-C as a hole portion as an example, the hole portion may be a through hole penetrating the blocking member 3042, wherein the extending direction of the through hole is different from the moving direction of the blocking member 3042. For example, the extending direction of the through hole is perpendicular to the moving direction of the blocking member 3042. The present application is not limited thereto, and the hole portion may also be a hole with a bottom provided in the blocking member 3042.

[0088] In the case where the engaging portion 3042-C is a hole, the blocking member 3042 needs to be accommodated in the through hole A at a specified rotation angle so that the hole is located at a position capable of engaging with the locking state switching member 305. Similar to the form in which the engaging portion 3042-C is a groove, the rotation angle of the blocking member 3042 can be marked or guaranteed in the aforementioned manner.

[0089] The position of the hole in the up-down direction of the blocking member 3042 may be such that when the locking state switching member 305 is engaged with the hole, the lower end of the blocking member 3042 does not abut against the base 301 .

[0090] In some embodiments, the main body 3041 may be provided with a second hole portion, which extends in a direction different from the moving direction of the blocking member 3042 and is used to accommodate the locking state switching member 305 .

[0091] When the locking state switching member 305 is located in the second hole portion and the blocking member 3042 is located in the second position, the locking state switching member 305 is engaged with the blocking member 3042 .

[0092] The present application is not limited thereto, and the second hole portion may not be provided in the main body 3041. For example, when the locking state switching member 305 abuts against the end (e.g., the upper end) of the main body 3041 away from the base and the blocking member 3042 is located in the second position, the locking state switching member 305 engages with the blocking member 3042. That is, when the locking state switching member 305 is located on the upper end surface of the main body 3041, the locking state switching member 305 engages with the blocking member 3042 to keep the blocking member 3042 in the second position where it does not abut against the base 301.

[0093] In some embodiments, Figure 6a and Figure 6b As shown, a groove C may be provided on the side of the main body 3041, and the groove C may be used to accommodate the portion of the locking state switching member 305 located outside the second hole portion, so as to prevent the locking state switching member 305 from interfering with other components of the lifting platform 300. For example, the locking state switching member 305 is an L-shaped wrench, wherein the first rod of the L-shaped wrench is accommodated in the second hole portion, and the second rod is accommodated in the groove C.

[0094] In some embodiments, Figure 6a and Figure 6b As shown, the locking assembly 304 may further include a limiting portion 3043 , which is used to limit the locking state switching member 305 when the locking state switching member 305 is connected to the locking assembly 304 to prevent the locking state switching member 305 from sliding out of the locking assembly 304 .

[0095] like Figure 6a and Figure 6b As shown, the limiting portion 3043 can be arranged at the edge of the groove C, and at least a portion of the limiting portion 3043 covers the opening of the groove C, thereby reliably preventing the locking state switching member 305 from sliding out.

[0096] The limiting portion 3043 can be in various forms. For example, the limiting portion 4043 can include a screw and a blocking sheet. The screw passes through the through hole of the blocking sheet and is installed on the edge of the groove C. At least a portion of the blocking sheet extends to the opening of the groove C.

[0097] The present application is not limited thereto, and the locking assembly 304 may also not include a limiting portion. For example, the locking state switching member 305 and the engaging portion 3042-C of the blocking member 3042 may be provided with matching threads, etc., so that the locking state switching member 305 can be prevented from sliding out by the threads.

[0098] In some embodiments, in order to enable the blocking member 3041 to reliably abut against the base 301, an elastic component may be provided in the locking assembly 304. The elastic component may be accommodated in the through hole A and is used to apply a force to the blocking member 3041 to move the blocking member 3041 toward the base 301.

[0099] Figure 8 is another schematic diagram of the locking assembly of an embodiment of the present application, Fig. 9 is another schematic diagram of the locking assembly and the locking state switching member of the embodiment of the present application. Figure 8 and Fig. 9 sectional views of the elastic component 309 in different states are shown respectively. Figure 8 and Fig. 9 As shown, the elastic component 309 is disposed inside the blocking member 3042 .

[0100] like Figures 7 to 9 As shown, the first end 3042-A of the blocking member 3042 away from the base 301 is provided with a first hole portion D. The locking assembly 304 further includes a guide member 3010. One end (e.g., the upper end) of the guide member 3010 is fixedly connected to the main body 3041, and the other end (e.g., the lower end) is located in the first hole portion D, and the blocking member 3042 can move along the guide member 3010.

[0101] like Figure 8 and Fig. 9 As shown, the elastic member 309 is received in the first hole portion D, one end (e.g., the lower end) of the elastic member 309 abuts against the bottom of the first hole portion D, and the other end (e.g., the upper end) abuts against the guide member 3010. Thus, when the locking state switching member 305 is engaged with the blocking member 3042, the blocking member 3042 is located at the second position, the distance between the first hole portion D and the guide member 3010 is reduced, and the elastic member 309 is in the first compressed state; after the locking state switching member 305 is removed from the locking assembly 304, the blocking member 3042 moves from the second position to the first position under the action of the elastic member 309 and gravity, the distance between the first hole portion D and the guide member 3010 is increased, and the elastic member 309 is in the natural state or the second compressed state, wherein the compression degree of the second compressed state is lower than the compression degree of the first compressed state.

[0102] above Figures 8 to 9 The structure in which the elastic component 309 is arranged inside the blocking member 3042 is shown. The present application is not limited thereto, and the elastic component 309 may also be arranged on the outer peripheral side of the blocking member 3042.

[0103] Fig.10 Schematic diagram of a locking assembly according to an embodiment of the present application. Fig.10As shown, the elastic component 309 is arranged on the outer peripheral side of the blocking member 3042. The upper end of the elastic component 309 abuts against the main body 3041, and the lower end abuts against the blocking member 3042. Therefore, when the locking state switching member 305 is engaged with the blocking member 3042, the blocking member 3042 is located in the second position, and the elastic component 309 is in the third compressed state; after the locking state switching member 305 is removed from the locking assembly 304, the blocking member 3042 moves from the second position to the first position under the action of the elastic component 309 and gravity, and the elastic component 309 is in the natural state or the fourth compressed state, wherein the compression degree of the fourth compressed state is lower than that of the third compressed state.

Thus, the user only needs to remove the locking state switching member from the locking assembly to lock the lifting platform, that is, the lifting platform is locked by a removal operation rather than an installation operation. Thus, the locking operation can be simplified, which helps to avoid safety problems.
