Description

Technical Field

[0001] This utility model relates to the field of lift technology, specifically a lift base assembly with quick assembly and disassembly function. Background Technology

[0002] Scissor lifts, as key equipment in the automotive repair industry, are widely used in various repair shops, 4S stores, and tire service locations to provide necessary lifting support for vehicle chassis operations. With the increasing demands of modern repair shops for space utilization, equipment layout flexibility, and cross-workstation scheduling efficiency, lifting equipment needs to possess greater mobility and adaptability. Especially in scenarios such as temporary work areas, multi-brand repair centers, and teaching demonstration environments, the equipment must be able to be quickly repositioned or stored according to operational needs.

[0003] According to CN210065046U, a multi-functional scissor lift base fixing device is disclosed. This technology discloses a structure including a lift base and a positioning post; the positioning post penetrates the lift base and includes an adjusting component, a locking component, and a clamping component. The adjusting component includes a connecting rod, a guide hole that passes through a bolt head and the connecting rod, and a through hole communicating with the guide hole. A support column is provided on the through hole. The locking component includes a guide rod, a first support rod, two second support rods, and a baffle. The guide rod is installed in the guide hole and connected to the baffle via the first support rod. Two second support rods are fixed on the first support rod. A first telescopic spring is connected to the first support rod and a limiting component. A second telescopic spring is provided on the baffle. The clamping component includes a connecting cylinder and two limiting fans. This technology has the technical effect of improving the stability of the lift base and the safety during operation through the structural design of the adjusting component, clamping component, and locking component, and is also convenient for installation and disassembly.

[0004] The aforementioned scissor lifts are fixed to the foundation with anchor bolts, which means that the equipment position cannot be adjusted once installed. This makes it difficult to meet the needs of modern maintenance workshops for flexible equipment layout, efficient cross-workstation scheduling, and rapid deployment of temporary work sites, severely limiting the equipment's usage scenarios and space utilization. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lift base assembly with quick assembly and disassembly functions. Through a foot-operated unlocking mechanism, it utilizes spring force to achieve automatic locking, enabling the scissor lift to be quickly installed or disassembled. This allows for operation by a single person, significantly improving the efficiency of equipment movement and deployment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lift base assembly with quick assembly and disassembly function, comprising a scissor lift, wherein the scissor lift is provided with a base mechanism for realizing the quick assembly and disassembly of the lift, the base mechanism comprising:

[0007] The connecting components include connectors fixed at the four corners of the bottom of the scissor lift, and the connectors have locking holes inside.

[0008] The fixed assembly includes a base frame located below the scissor lift. The base frame has cavities at both the front and rear ends. Connecting holes are provided on the left and right sides of the upper end of the cavities. A shaft is rotatably installed between the front and rear ends of the base frame. A first gear is fixed at both the front and rear ends of the shaft. A balance bar is fixed at both the upper and lower ends inside the cavities. A slider is slidably installed on the balance bar. A lock head is fixed at the outer end of the slider and matches the lock hole. A first rack is fixed at the inner end of the slider. A spring is installed on the balance bar.

[0009] The drive assembly is mounted on the fixed assembly and is used to drive the insertion and separation of the lock head and the keyhole.

[0010] Preferably, the drive assembly includes a reinforcing frame fixed between the left and right ends of the base frame, a second rack is laterally slidably installed inside the reinforcing frame, a guide rod is fixed to the right end of the second rack, and a second gear is fixed in the middle of the shaft and meshes with the second rack for transmission.

[0011] Preferably, the drive assembly further includes a housing fixed to the outer wall of the right end of the bottom frame, a guide plate is longitudinally slidably installed inside the housing, the guide plate has an inclined groove inside, and the guide plate is slidably connected to the guide rod through the inclined groove, and a foot pedal is fixed at the upper end of the guide plate.

[0012] Preferably, the first gear meshes with the first racks on the upper and lower sides to form a synchronous reverse transmission structure.

[0013] Preferably, the spring is located between the first rack and the inner wall of the cavity, and is used to provide a preload force for the slider to drive the lock head into the lock hole.

[0014] Preferably, the guide rod is slidably engaged with the reinforcing frame to limit the movement trajectory of the second rack.

[0015] Beneficial effects

[0016] This invention provides a lift base assembly with quick assembly and disassembly capabilities. Compared with the prior art, it has the following advantages:

[0017] 1. When installing a scissor lift, align the connector at its bottom with the connecting hole on the base frame and lower it. Under the preload of the spring, the locking head automatically inserts into the locking hole of the connector to complete the locking and fixing. When it is necessary to unlock, the drive assembly drives the shaft to rotate, which drives the first gear fixed at both ends to rotate synchronously. The first gear meshes with the first racks on the upper and lower sides, pushing the two sliders to slide towards each other along the balance bar. This overcomes the spring force and causes the locking head to exit from the locking hole, thus releasing the scissor lift. This achieves quick assembly and disassembly of the scissor lift and the base mechanism, improving the efficiency of equipment movement and deployment.

[0018] 2. When the operator steps down on the foot pedal, the guide plate slides longitudinally within the housing. At this time, the inclined groove inside the guide plate moves relative to the guide rod fixed on the second rack. Through the guiding action of the inclined groove, the longitudinal linear motion is converted into lateral linear motion, thereby pushing the guide rod to move the second rack laterally. This causes the second rack to mesh with the second gear fixed in the middle of the shaft, converting the linear motion into rotational motion and causing the shaft to rotate synchronously. The operator can free their hands with a simple foot pedal action. While stepping down on the foot pedal to release the lock, the hands can immediately perform the separation or docking operation of the scissor lift and the base mechanism, which not only greatly improves the efficiency of disassembly and assembly operations, but also allows for quick disassembly and assembly that can be completed by one person.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a lift base assembly with quick assembly and disassembly function, including a scissor lift 1, a base mechanism 2 provided on the scissor lift 1 for realizing quick assembly and disassembly of the lift, the base mechanism 2 including:

[0027] The connecting component 21 includes connectors 211 fixed at the four corners of the bottom of the scissor lift 1, and the connectors 211 have locking holes 212 inside.

[0028] The fixed component 22 includes a base frame 221 located below the scissor lift 1. The base frame 221 has cavities 222 inside both the front and rear ends. The upper left and right sides of the cavity 222 have connecting holes 223. A shaft 224 is rotatably installed between the front and rear ends of the base frame 221. A first gear 225 is fixed at both the front and rear ends of the shaft 224. A balance bar 226 is fixed at both the upper and lower ends inside the cavity 222. A slider 227 is slidably installed on the balance bar 226. A lock head 228 is fixed at the outer end of the slider 227 and is adapted to the lock hole 212. A first rack 229 is fixed at the inner end of the slider 227. A spring 2210 is installed on the balance bar 226.

[0029] The drive component 23 is mounted on the fixed component 22 and is used to drive the insertion and separation of the lock head 228 and the lock hole 212.

[0030] In this embodiment, when the scissor lift 1 needs to be installed, its bottom connector 211 is aligned with the connector hole 223 on the base frame 221 and lowered. Under the preload of the spring 2210, the lock head 228 automatically inserts into the lock hole 212 of the connector 211 to complete the locking and fixing. When it is necessary to unlock, the drive assembly 23 drives the shaft 224 to rotate, which drives the first gear 225 fixed at both ends to rotate synchronously. The first gear 225 meshes with the first racks 229 on the upper and lower sides, pushing the two sliders 227 to slide towards each other along the balance bar 226, overcoming the elastic force of the spring 2210 and causing the lock head 228 to exit from the lock hole 212, thus releasing the scissor lift 1. This realizes the quick assembly and disassembly of the scissor lift 1 and the base mechanism 2, improving the efficiency of equipment movement and deployment.

[0031] Specifically, the drive assembly 23 includes a reinforcing frame 231 fixed between the left and right ends of the bottom frame 221. A second rack 232 is laterally slidably installed inside the reinforcing frame 231. A guide rod 233 is fixed to the right end of the second rack 232. A second gear 234 is fixed in the middle of the shaft 224 and meshes with the second rack 232 for transmission.

[0032] In this embodiment, when the operator steps down on the foot pedal 237, the guide plate 236 slides longitudinally within the housing 235. At this time, the inclined groove inside the guide plate 236 moves relative to the guide rod 233 fixed on the second rack 232. The longitudinal linear motion is converted into lateral linear motion through the guiding effect of the inclined groove, thereby pushing the guide rod 233 to move the second rack 232 laterally. The second rack 232 then meshes with the second gear 234 fixed in the middle of the shaft 224, converting the linear motion into rotational motion and causing the shaft 224 to rotate synchronously.

[0033] Specifically, the drive assembly 23 also includes a housing 235 fixed to the outer wall of the right end of the bottom frame 221. A guide plate 236 is longitudinally slidably installed inside the housing 235. An inclined groove is opened inside the guide plate 236, and the guide plate 236 is slidably connected to the guide rod 233 through the inclined groove. A foot pedal 237 is fixed to the upper end of the guide plate 236.

[0034] In this embodiment, the operator can free their hands simultaneously through a simple foot pedal action. While stepping on the foot pedal 237 to unlock, the hands can immediately perform the separation or docking operation between the scissor lift 1 and the base mechanism 2, which not only greatly improves the efficiency of disassembly and assembly operations, but also allows for quick disassembly and assembly that can be completed by one person.

[0035] Specifically, the first gear 225 meshes with the first racks 229 on the upper and lower sides to form a synchronous reverse transmission structure.

[0036] In this embodiment, when the shaft 224 rotates under the drive of the drive assembly 23, the first gear 225 fixed at both ends of it rotates synchronously. Through meshing transmission with the first racks 229 on the upper and lower sides, it drives the two sliders 227 to move in completely synchronous but opposite directions along the balance bar 226. This ensures that the two locking heads 228 can extend or retract simultaneously and at equal distances, so that the locking force on both sides of the connector 211 is completely symmetrical and balanced.

[0037] Specifically, the spring 2210 is located between the first rack 229 and the inner wall of the cavity 222, and is used to provide the slider 227 with a preload force to drive the lock head 228 into the lock hole 212.

[0038] Specifically, the guide rod 233 and the reinforcing frame 231 slide together to limit the movement trajectory of the second rack 232.

[0039] The working principle and usage process of this utility model are as follows: First, when the operator steps down on the foot pedal 237, the guide plate 236 slides longitudinally within the housing 235. At this time, the inclined groove inside the guide plate 236 moves relative to the guide rod 233 fixed on the second rack 232. Through the guiding effect of the inclined groove, the longitudinal linear motion is converted into the lateral linear motion, thereby pushing the guide rod 233 to move the second rack 232 laterally. The second rack 232 then meshes with the second gear 234 fixed in the middle of the shaft 224, converting the linear motion into rotational motion and causing the shaft 224 to rotate synchronously.

[0040] When the scissor lift 1 needs to be installed, its bottom connector 211 is aligned with the connector hole 223 on the base frame 221 and lowered. Under the preload of the spring 2210, the locking head 228 automatically inserts into the locking hole 212 of the connector 211 to complete the locking. When it is necessary to unlock, the drive assembly 23 drives the shaft 224 to rotate, which drives the first gear 225 fixed at both ends to rotate synchronously. The first gear 225 meshes with the first racks 229 on the upper and lower sides, pushing the two sliders 227 to slide towards each other along the balance bar 226. This overcomes the elastic force of the spring 2210 and causes the locking head 228 to exit from the locking hole 212, thus releasing the scissor lift 1. This achieves quick assembly and disassembly of the scissor lift 1 and the base mechanism 2, improving the efficiency of equipment movement and deployment.
