Description

Technical Field

[0001] This utility model belongs to the field of laboratory cart technology, and specifically relates to a special cart for chemical laboratories. Background Technology

[0002] In chemical laboratories, experimental operations often involve the frequent handling of various reagents, instruments, and samples. In order to improve experimental efficiency, ensure experimental safety, and reduce potential safety hazards (such as liquid spillage, container damage, cross-contamination, etc.) that may be caused by human handling, the demand for specialized transportation vehicles is increasing.

[0003] In the existing technology (application number CN212500521U, patent title: A Laboratory-Specific Trolley), the multi-layered placement of medicines and experimental equipment significantly increases the overall storage capacity of the trolley, reducing the need for laboratory personnel to move back and forth to retrieve medicines or equipment, thus improving their work efficiency. However, in implementing this technical solution, the inventors discovered at least the following problems in the existing technology:

[0004] Traditional laboratory carts are typically designed as two-tiered flatbed carts with railings and four wheels for manual pushing. Because the lower tier is low, users need to frequently bend over or squat to retrieve items, making the operation less intuitive and resulting in low retrieval efficiency. This is especially true in scenarios involving frequent moving and changing of experimental materials, which seriously affects the overall efficiency of the experimental process. Retrieving items while bent over or squatting can easily lead to accidental touches or slips due to unstable posture or obstructed vision, which can cause experimental equipment to fall, break, or even cause chemical leaks, contamination, or personal injury accidents.

[0005] Therefore, a special trolley for chemical laboratories needs to be designed to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model proposes a special trolley for chemical laboratories, which can avoid the problem that users need to frequently bend over or squat down when picking up and putting down items due to the low position of the lower compartment.

[0007] The technical solution of this utility model is:

[0008] This utility model proposes a special trolley for chemical laboratories, including a support trolley, a control panel fixedly connected to the side wall of the support trolley, and a trolley handle fixedly connected to the top of the support trolley, and further comprising:

[0009] A motor is fixedly connected to the bottom of the carrying trolley, and a threaded rod is fixedly connected to the output end of the motor. A dual-axis slide plate is threadedly connected to the outer wall of the threaded rod, and a slide rail is slidably connected to the outer wall of the dual-axis slide plate. The bottom of the slide rail is fixedly connected to the inner wall of the bottom of the carrying trolley.

[0010] Preferably, the outer wall of the dual-axis slide plate is rotatably connected to a parallel rod one, and the end of the parallel rod one away from the dual-axis slide plate is rotatably connected to a hinge seat one. The top of the hinge seat one is fixedly connected to a lower load-bearing carriage. The outer wall of the dual-axis slide plate is rotatably connected to a parallel rod two, and the end of the parallel rod two away from the dual-axis slide plate is fixedly connected to a hinge seat two. The top of the hinge seat two is fixedly connected to the bottom of the lower load-bearing carriage.

[0011] Preferably, a guide plate is fixedly connected to the bottom inner wall of the carrying trolley, an L-shaped guide groove is provided on the side wall of the guide plate, a guide rod is slidably connected to the inner wall of the L-shaped guide groove, and one end of the guide rod is fixedly connected to the side wall of the lower carrying compartment.

[0012] Preferably, the inner side of the carrying trolley is fixedly connected to a guide rail, the side wall of the guide rail is slidably connected to a sliding groove plate, the side wall of the sliding groove plate is fixedly connected to an upper carrying carriage, the bottom of the upper carrying carriage is fixedly connected to a connecting plate, the side wall of the connecting plate is fixedly connected to an electric telescopic rod, and the electric telescopic rod is fixedly connected to the top of the carrying trolley.

[0013] Preferably, the bottom of the carrying trolley is fixedly connected to casters, the bottom of the carrying trolley is fixedly connected to a drive wheel, the central shaft of the drive wheel is fixedly connected to a drive shaft, the outer wall of the drive shaft is fixedly connected to a driven bevel gear, and the side wall of the driven bevel gear is meshed with a drive bevel gear.

[0014] Preferably, a drive motor is fixedly connected to the side wall of the drive bevel gear, the top of the drive motor is fixedly connected to the bottom of the carrying trolley, and a storage battery is fixedly connected to the bottom of the carrying trolley.

[0015] This utility model has the following advantages and effects compared with the prior art:

[0016] 1. This chemical laboratory trolley initially slides the guide rod in the horizontal section of the L-shaped guide groove. Subsequently, the lower support carriage and the guide rod continue to move into the vertical section, guiding the lower support carriage to rise along the L-shaped guide groove. The L-shaped guide groove applies a constraint force to the guide rod, realizing the transition from horizontal displacement of the lower support carriage to vertical lifting. This allows the lower support carriage to be aligned with the upper support carriage in space, forming a double-layer synchronous operating platform. This effectively solves the inconvenience caused by the lower carriage being too low in traditional double-layer trolleys, requiring frequent bending or squatting to retrieve and place items. It facilitates the user to complete the storage and retrieval of items within the same visual and action area, especially during high-frequency handling, sample replacement, or multi-step experimental preparation, thereby improving the overall operational efficiency of the laboratory.

[0017] 2. This chemical laboratory trolley, after placing the special glassware holder, firstly, the control panel sends a reset command to the motor and electric telescopic rod, driving the threaded rod to rotate in the opposite direction, causing the lower carrying carriage to descend synchronously and return to its initial position. The electric telescopic rod then resets the upper carrying carriage, ensuring compactness and stability during transportation. Subsequently, the staff operates the control panel to further send motion control signals to the drive motor. The output shaft of the drive motor drives the drive bevel gear to rotate, and through meshing, transmits power to the driven bevel gear, thus transmitting power to the drive wheel to achieve the overall forward or backward movement of the trolley.

[0053] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0054] Example 1:

[0055] like Figures 1-6 As shown, this utility model provides a special trolley for chemical laboratories, including a carrying trolley 101, a control panel 102 fixedly connected to the side wall of the carrying trolley 101, and a trolley handle 103 fixedly connected to the top of the carrying trolley 101. The trolley handle 103 can control the movement direction of the device, and also includes:

[0056] A motor 201 is fixedly connected to the bottom of the carrying trolley 101. A threaded rod 202 is fixedly connected to the output end of the motor 201. A dual-axis slide plate 203 is threadedly connected to the outer wall of the threaded rod 202. A slide rail 204 is slidably connected to the outer wall of the dual-axis slide plate 203. The bottom of the slide rail 204 is fixedly connected to the inner wall of the bottom of the carrying trolley 101. A parallel rod 205 is rotatably connected to the outer wall of the dual-axis slide plate 203. A hinge seat 206 is rotatably connected to the end of the parallel rod 205 away from the dual-axis slide plate 203. The top of the hinge seat 206 is fixedly connected to... The lower support carriage 209 has a parallel rod 207 rotatably connected to the outer wall of the dual-axis slide plate 203. The end of the parallel rod 207 away from the dual-axis slide plate 203 is fixedly connected to the hinge seat 208. The top of the hinge seat 208 is fixedly connected to the bottom of the lower support carriage 209. This arrangement is such that when the motor 201 starts and drives the threaded rod 202 connected to its output shaft to rotate, it drives the dual-axis slide plate 203 to move linearly in the direction of the motor 201. The movement of the dual-axis slide plate 203 further pushes the parallel rod 205 and the parallel rod 207.

[0057] A guide plate 21 is fixedly connected to the bottom inner wall of the carrying trolley 101. An L-shaped guide groove 22 is provided on the side wall of the guide plate 21. A guide rod 23 is slidably connected to the inner wall of the L-shaped guide groove 22. One end of the guide rod 23 is fixedly connected to the side wall of the lower carrying carriage 209. This arrangement is so that the guide rod 23 can slide in the L-shaped guide groove 22 and move according to the groove trajectory of the L-shaped guide groove 22.

[0058] A guide rail 301 is fixedly connected to the inner side of the carrying trolley 101. A sliding groove plate 302 is slidably connected to the side wall of the guide rail 301. An upper carrying carriage 303 is fixedly connected to the side wall of the sliding groove plate 302. A slot 24 is opened on the inner side of the lower carrying carriage 209 and the upper carrying carriage 303. A connecting plate 304 is fixedly connected to the bottom of the upper carrying carriage 303. An electric telescopic rod 305 is fixedly connected to the side wall of the connecting plate 304. The electric telescopic rod 305 is a silent mini electric push rod SY-A04A. The electric telescopic rod 305 is fixedly connected to the top of the carrying trolley 101. This arrangement is so that the output end of the electric telescopic rod 305 drives the connecting plate 304 to move and drives the upper carrying carriage 303 to move horizontally along the guide rail 301 through the sliding groove plate 302, thus completing the horizontal displacement action of the upper carrying carriage 303.

[0059] The bottom of the carrying trolley 101 is fixedly connected to casters 401 and drive wheels 402. A drive shaft 403 is fixedly connected to the central shaft of the drive wheels 402. A driven bevel gear 404 is fixedly connected to the outer wall of the drive shaft 403. A drive bevel gear 405 is meshed with the side wall of the driven bevel gear 404. A drive motor 406 is fixedly connected to the side wall of the drive bevel gear 405. The top of the drive motor 406 is fixedly connected to the bottom of the carrying trolley 101. This arrangement is so that the output shaft of the drive motor 406 drives the drive bevel gear 405 to rotate, and transmits power to the driven bevel gear 404 through meshing, and then transmits power to the drive wheels 402 to realize the forward or backward movement of the trolley as a whole. A battery 407 is fixedly connected to the bottom of the carrying trolley 101.

[0060] Working principle: When a special utensil holder needs to be placed on the device, the control panel 102 first activates the electric telescopic rod 305. Its output end drives the connecting plate 304 to extend axially, causing the upper support carriage 303 to move outward along the guide rail 301 via the sliding groove plate 302, completing the horizontal displacement of the upper support carriage 303. At the same time, the motor 201 starts and drives the threaded rod 202 connected to its output shaft to rotate, thereby driving the dual-axis slide plate 203 to move linearly in the direction of the motor 201. The movement of the dual-axis slide plate 203 further pushes the parallel rod 1 205 and the parallel rod 207. The guide rod 23 slides in the L-shaped guide groove 22 and moves according to the groove trajectory of the L-shaped guide groove 22: In the initial stage, the guide rod 23 slides in the L-shaped guide groove 22. The lower support carriage 209 slides in the horizontal section of the L-shaped guide groove 22, and then the guide rod 23 continues to move into the vertical section, guiding the lower support carriage 209 to rise along the L-shaped guide groove 22. The L-shaped guide groove 22 applies a constraint force to the guide rod 23, realizing the motion conversion from the horizontal displacement of the lower support carriage 209 to the vertical lifting, so that the lower support carriage 209 is aligned with the upper support carriage 303 in space, forming a double-layer synchronous operation platform. This effectively solves the problem of inconvenience caused by the lower carriage being too low in traditional double-layer trolleys and the need to frequently bend over or squat to pick up and put down items. Then, a special utensil bracket can be accurately embedded into the slots 24 located on the lower support carriage 209 and the upper support carriage 303 to achieve quick positioning and fixation.

[0061] After placing the special container holder, the control panel 102 first sends a reset command to the motor 201 and the electric telescopic rod 305, driving the threaded rod 202 to rotate in the opposite direction, causing the lower carrying carriage 209 to descend synchronously and return to its initial position. The electric telescopic rod 305 then resets the upper carrying carriage 303, ensuring compactness and stability during transportation. Subsequently, the operator operates the control panel 102 to send motion control signals to the drive motor 406. The output shaft of the drive motor 406 drives the drive bevel gear 405 to rotate, and through meshing, transmits power to the driven bevel gear 404, thereby transmitting power to the drive wheel 402 to realize the overall forward or backward movement of the trolley.

[0062] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
