Description

Technical Field

[0001] This invention relates to the field of electronic weighing equipment technology, and in particular to an electronic scale support mechanism that allows for rapid locking and disengagement. Background Technology

[0002] An electronic scale is a modern weighing instrument based on force sensor technology that converts the weight signal of an object into an electrical signal and processes it to achieve accurate weight display. It is widely used in many scenarios such as home kitchens, commercial retail, industrial production, and logistics warehousing. It mainly consists of a load-bearing unit (such as a weighing pan or platform), a weighing sensor, a signal processing unit, a display unit, and a support unit (such as a support leg mechanism).

[0003] The main support legs of the electronic scale are in direct contact with the ground and are prone to wear, deformation or damage after long-term use. By quickly separating them from the base, the damaged support legs can be replaced directly without disassembling the entire scale body.

[0004] In existing technologies, when quickly locking and disengaging the feet of electronic scales, the main feet are rigidly connected directly to the base. This usually requires the use of tools such as screwdrivers to remove the bolts, making it impossible to achieve quick separation and locking. Furthermore, the fixed feet do not have a storage function. When not in use, the feet protrude from the bottom of the base, not only taking up extra storage space but also being prone to structural damage during handling or stacking due to bumps. After disassembly, the feet usually need to be stored separately, making them easy to lose, and it is impossible to directly store the feet on the base.

[0005] Therefore, it is necessary to provide an electronic scale support leg mechanism that allows for rapid locking and disengagement to solve the aforementioned technical problems. Summary of the Invention

[0006] The technical problem solved by this invention is to provide an electronic scale support leg mechanism that can quickly lock and automatically eject the main support leg without tools, flip and store the main support leg, and has high flexibility in quick locking and separation.

[0007] To solve the above-mentioned technical problems, the present invention provides a fast locking and disengaging electronic scale support mechanism, comprising: a base, a weighing pan, and four main support legs.

[0010] Preferably, any set of ejection components includes a limiting seat, a top plate, and a second spring. The limiting seat is fixedly installed on the top inner wall of the mounting groove, the top plate is slidably installed in the limiting seat, and the bottom of the top plate is in contact with the top of the I-shaped support plate. The second spring is disposed in the limiting seat, and the two ends of the second spring are fixedly connected to the limiting seat and the top plate, respectively.

[0011] Preferably, the base has four third slots and a lifting support device, which includes four sets of auxiliary leg support components and a hidden pulley assembly.

[0012] Preferably, any set of the secondary leg support components includes a secondary support leg, a first gear, a third rack, a second gear, and a second rack. The secondary support leg is slidably installed in the third groove. The inner wall of one side of the third groove is provided with a mounting communication port, which communicates with the first groove. A gear shaft is rotatably installed in the mounting communication port. The first gear and the second gear are both fixedly installed on the outer wall of the gear shaft. The second rack is fixedly installed on the outer wall of one side of the main support leg, and the second gear meshes with the second rack. The third rack is fixedly installed on the outer wall of one side of the second rack, and the first gear meshes with the third rack.

[0013] Furthermore, the auxiliary support leg and the main support leg are each provided with an assembly groove on the side that is close to each other, and the second rack and the third rack are respectively fixedly installed in the two assembly grooves.

[0014] Preferably, the concealed pulley assembly includes four rollers, two first racks, a fixed shaft, a lever, and an arc-shaped bracket. Each of the four third slots has a hidden groove on its inner wall near the second slot, and the hidden groove communicates with the second slot. Each of the four auxiliary legs has a rotating shaft rotatably mounted inside, and one end of each of the four rotating shafts extends into the hidden groove and is fixedly mounted with a third gear.

[0016] Furthermore, each of the four auxiliary support legs has an insert groove at its bottom, and the roller, rotating shaft, and roller seat are all disposed within the insert groove.

[0017] Compared with related technologies, the electronic scale support leg mechanism for quick locking and disengagement provided by the present invention has the following beneficial effects:

[0018] This invention provides a fast locking and disengaging electronic scale support mechanism. Through the cooperation of two sets of locking and disengaging components, four sets of ejection components, and internal parts, it achieves rapid locking and convenient disengagement between the main support leg and the base. The locking and disengaging components, via a turntable and hinge rod, drive the abutment rod to slide along the groove. Combined with the engagement of multi-position locking rods and locking shafts, fast locking and disengagement can be achieved simply by turning a knob, without the need for tools or bolts. The ejection components, aided by the elastic extension of a second spring, push the top plate against the I-shaped support plate. After unlocking, the I-shaped support plate and the main support leg are automatically ejected from the second recess, eliminating the need for manual disassembly and making operation simple and efficient. Simultaneously, the I-shaped support plate can be flipped over and re-embedded into the base, completing the storage of the main support leg. This significantly reduces the space occupied by the electronic scale when not in use, improving the mechanism's storage convenience and space utilization.

[0019] Through the cooperation of four sets of auxiliary leg support components and internal components, the auxiliary leg support components drive the first and second gears on the gear shaft through the second rack when the main support leg is raised and lowered, which in turn drives the third rack to drive the auxiliary support leg to rise and fall synchronously along the third groove. When the main support leg is retracted, the auxiliary support leg automatically moves down to contact the ground to form support, avoiding direct contact between the base and the ground and causing wear, while enhancing the stability of the electronic scale when it is placed. When the main support leg is unfolded for use, the auxiliary support leg automatically retracts into the third groove without affecting the normal weighing function of the main support leg.

[0020] Through the cooperation of the concealed pulley assembly and its internal components, the concealed pulley assembly, through the meshing of the slide rod, the first rack and the third gear inside the secondary support leg, combined with the operation of the lever and the arc-shaped bracket, can drive the rollers to flip and unfold from the mounting groove at the bottom of the secondary support leg when the electronic scale is stored in the main support leg and the secondary support leg. This enables convenient movement of the electronic scale without manual handling, reducing the labor intensity during movement. When movement is not required, the rollers can be hidden in the mounting groove without affecting the support stability of the secondary support leg, improving the flexibility of use and the range of applicable scenarios of the electronic scale.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] First embodiment:

[0041] Please refer to the following: Figures 1-9 In the first embodiment of the present invention, the fast-locking and disengaging electronic scale support mechanism includes: a base 2, a weighing pan 1, and four main support legs 3. The weighing pan 1 is disposed on top of the base 2, and the four main support legs 3 are disposed below the base 2. The bottom of the base 2 is provided with a second recess 13, and an I-shaped support plate 5 is disposed within the second recess 13. The four main support legs 3 are fixedly installed on the bottom of the I-shaped support plate 5. The top of the second recess 13 is provided with four first recesses 10. The first recesses 10 are precisely fitted to the main support legs 3 and play a positioning and guiding role when the main support legs 3 are stored, preventing the main support legs 3 from shaking or shifting. The size matches the main support legs 3, and the first recesses 10 can fully accommodate the main support legs 3, reducing the overall volume of the electronic scale when it is not in use. To improve space utilization, the four first slots 10 are respectively adapted to the four main support legs 3. After separating the I-shaped support plate 5 from the base 2, the I-shaped support plate 5 is flipped so that the four main support legs 3 face the top. The I-shaped support plate 5 is then inserted into the second slot 13 again, and the four main support legs 3 are respectively inserted into the four first slots 10. This allows for the storage of the I-shaped support plate 5 and the four main support legs 3. The top of the second slot 13 is also provided with a mounting slot 14. A rotating rod 12 is rotatably installed in the mounting slot 14. One end of the rotating rod 12 extends to the outside of the base 2 and is fixedly installed with a knob 4. Two sets of locking and separating components are provided on the rotating rod 12 and inside the I-shaped support plate 5. Four sets of ejection components are provided in the mounting slot 14.

[0042] Each locking and separating assembly includes two abutment rods 16, a turntable 20, two multi-position locking rods 22, and a movable rod 8. The turntable 20 is fixedly installed on the outer wall of the rotating rod 12. The inner walls on both sides of the mounting groove 14 are provided with sliding grooves 21, which are connected to the first recess 10. The two abutment rods 16 are slidably installed in the two sliding grooves 21. One end of two hinge rods 19 is rotatably installed on the turntable 20, and the other end of the two hinge rods 19 is rotatably installed on one end of the two abutment rods 16 respectively. Iron blocks 15 are fixedly installed on the ends of the two abutment rods 16 that are far apart from each other. Two main support legs are also included. 3. Each side of the two plates has a slot, and each slot contains a magnet 23. Two multi-position locking rods 22 are fixedly installed at the bottom of the two abutment rods 16. The top of the I-shaped support plate 5 has a strip groove, and the movable rod 8 is set in the strip groove. The top of the strip groove has a maintenance plate for limiting the movable rod 8. Two U-shaped fixing seats 7 are fixedly installed on the top of the movable rod 8. The two U-shaped fixing seats 7 extend out of the strip groove and are fixedly installed with locking shafts 6. One end of multiple first springs 9 is fixedly installed on the top of the movable rod 8, and the other end of the multiple first springs 9 is fixedly attached to the maintenance plate. The fixed connection and locking separation assembly, via the turntable 20 and hinge rod 19, drives the abutment rod 16 to slide along the slide groove 21. Combined with the engagement of the multi-position locking rod 22 and the locking shaft 6, the locking and separation can be quickly achieved by simply turning the knob 4, without the need for tools or bolts. When it is necessary to separate the main support leg 3 from the base 2, the knob 4 on the outside of the base 2 is rotated clockwise. The knob 4 drives the rotating rod 12 and the turntable 20 fixed on the rotating rod 12 to rotate together. The turntable 20 drives the two abutment rods 16 to slide along the slide groove 21 towards each other via the hinge rod 19. During the sliding process, the bottom of the abutment rod 16 The multi-position locking lever 22 slides together with the abutment lever 16. When the locking shaft 6 passes through multiple arc-shaped grooves in sequence, it will drive the movable lever 8 to compress the first spring 9 and move upward until the locking shaft 6 moves out of the arc-shaped groove at the top of the multi-position locking lever 22, thereby disassembling the main support leg 3. When quick locking is required, turn the knob 4 counterclockwise, and the two abutment levers 16 slide along the slide groove 21 in a direction away from each other. The multi-position locking lever 22 drives the locking shaft 6 to rise through the inclined surface, and the movable lever 8 compresses the first spring 9 and moves upward until the locking shaft 6 is engaged in the arc-shaped groove at the top of the multi-position locking lever 22, thereby achieving quick locking.

[0043] The top of the multi-position locking lever 22 is provided with multiple arc-shaped grooves. The outer wall of the locking shaft 6 is adapted to the multiple arc-shaped grooves. The end of the multi-position locking lever 22 near the iron block 15 is provided with an inclined surface. The inclined surface at the end near the iron block 15 can automatically lift the locking shaft 6 when the abutment rod 16 moves, avoiding rigid collision between the locking shaft 6 and the end of the abutment rod 16, and improving the smoothness of the structural transmission.

[0044] Each set of ejection components includes a limiting seat 18, a top plate 11, and a second spring 17. The limiting seat 18 is fixedly installed on the top inner wall of the mounting groove 14. The top plate 11 is slidably installed in the limiting seat 18, and the bottom of the top plate 11 contacts the top of the I-shaped support plate 5. The second spring 17 is set in the limiting seat 18, and the two ends of the second spring 17 are fixedly connected to the limiting seat 18 and the top plate 11, respectively. After the main support leg 3 is disassembled, the second spring 17 in the limiting seat 18 extends elastically, pushing the top plate 11 downward to press the I-shaped support plate 5, and simultaneously ejecting the I-shaped support plate 5 and the four main support legs 3 at the bottom out of the second recess 13, realizing the rapid separation of the I-shaped support plate 5 from the base 2. The ejection component pushes the top plate 11 to press the I-shaped support plate 5 with the elastic extension of the second spring 17. After unlocking, it can automatically eject the I-shaped support plate 5 and the main support legs 3 out of the second recess 13 without the need for manual additional force to disassemble, making the operation simple and efficient.

[0045] In this embodiment:

[0046] When it is necessary to detach the main support leg 3 from the base 2, rotate the knob 4 on the outside of the base 2 clockwise. The knob 4 drives the rotating rod 12 and the turntable 20 fixed on the rotating rod 12 to rotate together. The turntable 20 drives the two abutment rods 16 to slide along the slide groove 21 towards each other through the hinge rod 19. During the sliding process, the multi-position locking rod 22 at the bottom of the abutment rod 16 slides together with the abutment rod 16. When the locking shaft 6 passes through multiple arc-shaped grooves in sequence, it will drive the movable rod 8 to compress the first spring 9 and move it upward until the locking shaft 6 moves out of the arc-shaped groove at the top of the multi-position locking rod 22 in sequence, thus realizing the separation of the main support leg 3. During disassembly, the second spring 17 inside the limiting seat 18 extends elastically, pushing the top plate 11 downward to press the I-shaped support plate 5, and simultaneously pushing the I-shaped support plate 5 and the four main support legs 3 at the bottom out of the second groove 13, realizing the rapid separation of the I-shaped support plate 5 from the base 2. When rapid locking is required, turn the knob 4 counterclockwise, and the two abutment rods 16 slide along the slide groove 21 in a direction away from each other. The multi-position locking rod 22 drives the locking shaft 6 to rise through the inclined surface, and the movable rod 8 compresses the first spring 9 to move upward until the locking shaft 6 is inserted into the arc-shaped groove at the top of the multi-position locking rod 22, realizing rapid locking.

[0047] After separation, flip the I-shaped support plate 5 so that the four main support legs 3 face the top, and then insert the I-shaped support plate 5 into the second groove 13 again. The four main support legs 3 are respectively inserted into the four first grooves 10. At this time, rotate the knob 4 counterclockwise. The knob 4 drives the rotating rod 12 and the turntable 20 fixed on the rotating rod 12 to rotate together. Through the hinge rod 19, the two abutment rods 16 are driven to slide along the slide groove 21 in a direction away from each other. At this time, the iron block 15 is inserted into the slot, and the magnet 23 attracts the iron block 15, thus completing the storage of the I-shaped support plate 5 and the four main support legs 3.

[0048] Second embodiment:

[0049] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] Please refer to the following: Figures 10-17 In the fast locking and disengaging electronic scale support mechanism provided in this embodiment, the base 2 is provided with four third slots 29, and the base 2 is provided with a lifting support device, which includes four sets of auxiliary leg support components and a hidden pulley assembly.

[0051] Each set of auxiliary leg support components includes an auxiliary leg 33, a first gear 36, a third rack 40, a second gear 37, and a second rack 32. The auxiliary leg 33 is slidably installed in the third groove 29. A mounting connection port is provided on one inner wall of the third groove 29, communicating with the first groove 10. A gear shaft is rotatably installed within the mounting connection port. The first gear 36 and the second gear 37 are both fixedly installed on the outer wall of the gear shaft. The second rack 32 is fixedly installed on one outer wall of the main leg 3, and the second gear 37 meshes with the second rack 32. The third rack 40 is fixedly installed on the second… On one side of the outer wall of the rack 32, the first gear 36 meshes with the third rack 40. When the main support leg 3 is raised or lowered, the second rack 32 drives the first gear 36 and the second gear 37 on the gear shaft to move together, driving the third rack 40 to drive the auxiliary support leg 33 to move up and down synchronously along the third groove 29. When the main support leg 3 is retracted, the auxiliary support leg 33 automatically moves down to contact the ground to form support, avoiding the base 2 from directly contacting the ground and causing wear, while enhancing the stability of the electronic scale when it is placed. When the main support leg 3 is unfolded for use, the auxiliary support leg 33 automatically retracts into the third groove 29, without affecting the normal weighing function of the main support leg 3.

[0052] The auxiliary support leg 33 and the main support leg 3 are respectively provided with assembly slots on the side that are close to each other, and the second rack 32 and the third rack 40 are respectively fixedly installed in the two assembly slots.

[0053] The concealed pulley assembly includes four rollers 35, two first racks 24, a fixed shaft 25, a lever 28, and an arc-shaped bracket 26. Each of the four third grooves 29 has a hidden groove 39 on its inner wall near the second groove 13, and the hidden groove 39 communicates with the second groove 13. Each of the four auxiliary support legs 33 has a rotating shaft 34 rotatably mounted inside it, and one end of each of the four rotating shafts 34 extends into the hidden groove 39 and is fixedly mounted with a third gear 38. Roller seats are fixedly mounted on the outer walls of each of the four rotating shafts 34. The four rollers 35 are rotatably mounted in the four roller seats. Sliding rods 31 are slidably mounted on both outer walls of the I-shaped support plate 5. The two first racks 24 are fixedly mounted on the outer walls of the two sliding rods 31 on their opposite sides. One end of each slide rod 31 extends to the outside of the I-shaped support plate 5. The two ends of the fixed shaft 25 are respectively fixedly connected to the two slide rods 31. The lever 28 is rotatably installed on one side of the outer wall of the base 2. A guide rod 30 is slidably installed inside the lever 28. The bottom end of the guide rod 30 extends to the outside of the lever 28. The arc-shaped bracket 26 is fixedly installed at the bottom end of the guide rod 30. Through the meshing of the slide rod 31, the first rack 24 and the third gear 38 in the secondary support leg 33, combined with the operation of the lever 28 and the arc-shaped bracket 26, when the electronic scale is stored in the main support leg 3 and the secondary support leg 33 for support, the drive roller 35 can be flipped and unfolded from the embedded groove at the bottom of the secondary support leg 33, realizing the convenient movement of the electronic scale without manual handling, reducing the labor intensity during movement.

[0054] One end of a third spring 27 is fixedly installed on the top of the arc-shaped card holder 26, and the other end of the third spring 27 is fixedly connected to the lever 28. The third spring 27 is sleeved on the outside of the guide rod 30.

[0055] The bottom of each of the four auxiliary support legs 33 is provided with an insert groove. The rollers 35, the rotating shaft 34 and the roller seat are all set in the insert groove. When there is no need to move, the rollers 35 can be hidden in the insert groove without affecting the support stability of the auxiliary support legs 33, thereby improving the flexibility of use and the range of applicable scenarios of the electronic scale.

[0056] In this embodiment:

[0057] When the main support leg 3 is inserted into the first groove 10 and the second groove 13 together with the I-shaped support plate 5, the second rack 32 on one side of the main support leg 3 moves upward synchronously. At this time, it meshes with the second gear 37 and drives the second gear 37 to rotate. The second gear 37 drives the coaxial first gear 36 to rotate through the gear shaft. The first gear 36 drives the third rack 40 meshing with it to move downward, pushing the auxiliary support leg 33 to slide downward along the third groove 29 until the bottom of the auxiliary support leg 33 contacts the ground, forming a temporary fulcrum support, improving the placement stability of the electronic scale, and avoiding damage to the base 2 caused by placing it directly on the ground.

[0058] When the main support leg 3 slides down out of the first groove 10, the second rack 32 moves down accordingly. Through the reverse transmission of the gear set, it drives the third rack 40 to move up, pulling the auxiliary support leg 33 to slide up along the third groove 29 until it is completely stored in the third groove 29, thus completing the hiding of the auxiliary support leg 33.

[0059] When the I-shaped support plate 5 is flipped and embedded into the second groove 13, the arc-shaped bracket 26 will be locked on the outer wall of the fixed shaft 25. When it is necessary to move the electronic scale after the main support leg 3 is stored, push the lever 28 towards the weighing pan 1. The arc-shaped bracket 26 will pull the two sliding rods 31 outward and drive the first rack 24 to move along with it. When the secondary support leg 33 is lowered, the third gear 38 will mesh with the first rack 24. When the secondary support leg 33 is raised, the third gear 38 will no longer mesh with the first rack 24. When the first rack 24 moves, it will drive the third gear 38 and the rotating shaft 34 to rotate synchronously, causing the roller seat to rotate counterclockwise and extend the roller 35 out of the mounting groove until the roller 35 rotates out of the mounting groove at the bottom of the secondary support leg 33 and contacts the ground. Release the lever 28 to realize the flipping and unfolding of the roller 35, and realize the convenient movement of the electronic scale through the roller 35.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
